wall - eyed monocular internuclear ophthalmoplegia ( wemino ) with contraversive ocular tilt reaction has not been previously reported .
a 71-year - old woman suddenly developed blurred vision .
examination revealed left internuclear ophthalmoplegia , left exotropia , right hypotropia , and rightward head tilt .
magnetic resonance imaging showed a tiny infarction at the area of the left medial longitudinal fasciculus in the upper pons .

– This time hunter Rick Dyer has really captured Bigfoot—like really for real. And he's released an image of a creature that he says will ensure his place in history, the Huffington Post reports. "Bigfoot is not a tooth fairy—Bigfoot is real," he told KSAT. "The most important thing to me is being vindicated, letting people know that I am the best Bigfoot tracker in the world and it's not just me saying it." A self-proclaimed professional Bigfoot hunter, Dyer says he killed the beast in 2012 near San Antonio, Texas, after luring it with pork ribs he bought at Walmart. Dyer says he's shown the corpse to 130 people and recorded some of their reactions on video. "We definitely made them believers," he said. The Houston Chronicle offers one healthy dose of skepticism, noting that some in the "Bigfoot research community" think Dyer's Bigfoot looks suspiciously like a Lord of the Rings character. Still, Dyer also claims that "every test that you can possibly imagine" has been done on the body, including DNA tests and "3D optical scans." He previously released a grainy video that he claims shows his encounter with Bigfoot, and wrote an account of it that HuffPo calls "haphazardly written." He now promises to hold a news conference where he will show the Bigfoot corpse and his various test results. (With any luck he'll fare better than two other Bigfoot enthusiasts, one of whom was shot by a friend and another who was run over and killed while dressed as Bigfoot.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

– Hey, the Jersey Shore guidos have more important things to worry about than unknowingly gracing the cover of the Village Voice's “queer” issue—like how their abs look on said cover. “In my opinion the SitUaTIoN looks good as hell and that is my main concern,” wrote Mike “The Situation” Sorrentino on Facebook, adding that “it’s not for me to judge somebody’s sexual preference…it just so happens that The SitUaTiON has mass appeal.” At least one of his fellow Village Voice “queer issue” cover stars agree. “The Village Voice? That's awesome,” Vinny Guadagino tells E!. “I don't give a s--t, man. As long as I look good, that's all I care about.” And anyway, “I got a free pink hoodie out of it!” Want to see the cover shot? Click here. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Villagevoice.com The Jersey Shore boys love all their fans—including the gay ones. So it was a little surprising to read this morning that our pals Mike "The Situation" Sorrentino, Ronnie Ortiz-Magro and Vinny Guadagino were upset to find shirtless photos of themselves on the cover of the "Queer Issue" of New York City alternative newspaper the Village Voice... But just like Kathy Griffin, our favorite self-described "guidos" love their gays. "I don't give a s--t, man," Vinny just told me about being on the newspaper's annual gay-themed issue. "I've done so many photoshoots and they're pretty much all the same. "I go in there, do my thing, take my shirt off, get my hair and my make-up done and they dress me," he continued. "I take the pictures and wherever they end up, they end up." A report in today's New York Post claims that the Village Voice tricked the trio into doing the photo shoot by not telling them when the pics would actually run. "I know MTV and it's in their judgment to make sure they don't end up anywhere too crazy, but the Village Voice?" Vinny said. "That's awesome." The accompanying Voice story, headlined "The Guido Ideal," examines gay life on the Shore. "As long as I look good," Vinny said, "that's all I care about." Way back in December, The Situation told me that he doesn't mind his same-sex loving fans. "I'll be honest, I like the attention," he said, "I'm flattered if there are guys with different preferences that have crushes on me." Besides, being a "Queer" coverboy does have its perks. Vinny bragged, "I got a free pink hoodie out of it!" Want some more celeb scoop?

– "We ... would prefer our trademark not be misappropriated for political purposes." That's HBO's take on a Game of Thrones-like image of President Trump with the caption "Sanctions Are Coming November 5" that the president tweeted Friday, CNBC reports. The message—which imitates’ the show’s popular “Winter Is Coming” catchphrase and font—apparently references Trump’s re-imposing of sanctions on Iran. In its own tweet, HBO says, “How do you say trademark misuse in Dothraki?” referring to a fictional language from Game of Thrones. In reaction to Trump’s tweet, Sophie Turner, who portrays Sansa on the show, tweeted, “Ew.” ( Steven Tyler sent the president a cease-and-desist letter.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | HBO isn't happy that President Donald Trump used "Game of Thrones" imagery and language to promote sanctions against Iran. An image of Trump posted Friday featured a text overlay reading "Sanctions are coming." The font of the text is a near-match of the style used in HBO's mega-popular fantasy television series. The text itself appears to imitate "Winter is coming," one of the show's most popular slogans. In a statement to CNBC, HBO said, "We were not aware of this messaging and would prefer our trademark not be misappropriated for political purposes." HBO's official Twitter account followed up soon after, asking, "How do you say trademark misuse in Dothraki?" referring to a fictional language used by one of the groups in the show. Asked if HBO planned to take legal action, network spokesman Jeff Cusson told CNBC there were "no further steps." The White House did not immediately respond to CNBC's request for comment on HBO's statement. It was not immediately clear from Trump's tweet which sanctions he was referring to. But the White House's official Twitter account appeared to clarify in a follow-up shortly after Trump's tweet that the image was intended to reference sanctions on Iran. Trump's tweet also noted that the sanctions were "coming" on Monday, Nov. 5, when the administration says it will reimpose all U.S. sanctions on Iran that had been relaxed under the 2015 nuclear deal brokered during the Obama administration. This isn't the first time Trump has run afoul of HBO's parent company, Time Warner. The president has repeatedly hammered news network CNN, and his Justice Department opposed AT&T's acquisition of Time Warner, which was cleared by a federal judge in June. Some stars of "Game of Thrones," which is set to air its eighth and final season in 2019, responded to Trump's allegedly unauthorized use of the show's likeness. Maisie Williams, who portrays Arya Stark on the show, responded, "Not today." Sophie Turner, who plays Arya's sister Sansa, was even more succinct: "Ew," she said. While HBO objected to Trump's photo, the show's themes and catchphrases have often shown up in politics. Business Insider reported that Trump's 2016 rival, former Secretary of State Hillary Clinton, compared herself to another character, Cersei Lannister, in her memoir, "What Happened." "Crowds at Trump rallies called for my imprisonment more times than I can count," Clinton reportedly wrote. "They shouted 'Guilty! Guilty!' like the religious zealots in 'Game of Thrones' chanting 'Shame! Shame!' while Cersei Lannister walked back to the Red Keep." WATCH: Trump and Kudlow send mixed messages |

– A 23-year-old man in Alabama has become the latest person to follow a phone-tracking app all the way to his grave. Police say the man was shot dead outside a Baptist church in the Birmingham suburb of Fairfield Sunday night after he used an app to trace an iPhone that had been stolen from his car, AL.com reports. The victim "arrived on the scene and hit a button on the app that made the phone ring inside a vehicle," Fairfield Police Chief Leon Davis tells Reuters. "When he went to retrieve the phone inside the vehicle, the suspect shot and killed him." Davis says investigators believe the victim and the shooter knew each other. Davis offers the same advice that police in Canada gave after a similar murder last year: Don't risk your life for your phone by confronting thieves. "If you have an app on the phone, contact your local police department. Let the police do their job and recover your stolen property," the chief says, per NBC News. "Don't take these matters into your own hands—these things normally don't turn out too good." No arrests have been made in the case, but the chief says investigators are hunting a suspect known as "G Boy" or "G Bo" and have some "very good leads."

The 23-year-old victim’s phone was stolen from his car in Fairfield, Alabama, a suburb of Birmingham, said Fairfield Police Chief Leon Davis. The tracking app led the victim to a church parking lot near Miles College late on Sunday, Davis said. The man is believed to have “arrived on the scene and hit a button on the app that made the phone ring inside a vehicle,” the police chief said in an interview. “When he went to retrieve the phone inside the vehicle, the suspect shot and killed him.” The victim and the shooter apparently knew each other, Davis said. The suspect has not been arrested but police have “very good leads” as to his identity, he added. The case illustrates the danger of people trying to apprehend cell phone thieves on their own with the help of tracking apps, Davis said. “Notify police and let them handle the recovering,” he said. (Reporting by David Beasley in Atlanta; Editing by Colleen Jenkins and Lisa Shumaker) ||||| An investigation is underway after a deadly shooting in Fairfield. Fairfield police Chief Leon Davis said the 23-year-old victim was taken to UAB Hospital where he was pronounced dead upon arrival. He was shot twice in the chest, Davis said. The shooting happened about 8 p.m. on 58th Street outside Crumbey Bethel Primitive Baptist Church. Nearby Miles College was put on lockdown as a precaution, but Davis and school officials said no students were involved in the shooting and were never in any danger. The chief said they believe the victim was shot after he used an app to track his stolen iPhone phone which was stolen out of his car. Fairfield police are now searching for the shooter. He fled the scene in a gold 2015 or 2016 Nissan Maxima with chrome accents. Davis said they have a potential street name for the shooter: G-boy or G-bo. Three people - including a child - were wounded by gunfire in Fairfield Friday night after an altercation at Western Hills Mall. Police responded shortly after 7 p.m. to find a 21-year-old man shot in the leg and a 5-year-old boy grazed in the neck. The shooting occurred outside the Dr. Denim store near the mall's entrance. Their injuries were not life-threatening. Three other people were injured by flying debris. Police have not yet announced any arrests in that case. |

– If the idea of eating a $95 tiny wedge of cheese seems a little too, well, rich for your tastes, consider this: How often do you get the chance to dine on real gold? The Independent reports on England's "blingiest" cheese, a stilton flecked with edible gold leaf. Clawson Stilton Gold is apparently the most expensive stilton in the world (the $95 price tag is for a 3.5-ounce portion) and the priciest cheese in the whole UK. The Long Clawson Dairy in Leicestershire says an oil sheikh and a pop star have already inquired about the limited-edition cheese, and a rep for the dairy promises you'll get your money's worth: "You can see the gold clearly in the slices and we've not been shy with how much gold we've put in the batch." Should you worry you'll have a hard time swallowing such a costly item, fear not: You'll be helped along by a bit of liquid courage.

A whopping £6 price tag for a single cracker-sized wedge (if you divide the £60 slice into 10 portions) may seem a bit decadent to some but celebrities are already queuing up to get their hands on some of the swanky Stilton. Long Clawson Dairy in Leicestershire will make a limited edition run of it this Christmas and has already been contacted by a variety of interested parties including a Gulf-based oil sheikh and a famous pop star. Made from premium white Stilton shot-through with a combination of real edible gold leaf and real gold liqueur, its creators say it is Britain's "blingiest" cheese, 67 times more pricey than regular Stilton, which comes in at around 90p for 100g. At £60.87 per 100g slice, or £608 a kilo, Clawson Stilton Gold is the world's most expensive Stilton and the most expensive cheese of any kind made in the UK. Janice Breedon, a spokeswoman for Long Clawson Dairy, said: "For confidentiality reasons I can't publicly identify the people who have inquired about our Clawson Stilton Gold but, suffice to say, they are all very well known. "We wanted to create something special, a unique Stilton cheese, for the Christmas market - just a limited run to hopefully get more people interested in Stilton. "We're frankly amazed that word has leaked out and we're being contacted by some very important and well-heeled people about the cheese. "It does look amazing though. You can see the gold clearly in the slices and we've not been shy with how much gold we've put in the batch.

– If George Orwell were alive today, he would probably be less than thrilled to find that his vision of a dystopian future at the top of best-seller lists. Orwell's 1984, first published in 1949, is now at No. 1 on Amazon.com's best-seller list and publisher Penguin is planning to print another 75,000 copies to meet demand, according to the Hollywood Reporter. The surge in sales follows Kellyanne Conway's claim that the Trump administration was presenting "alternative facts" instead of falsehoods, an assertion critics described as distinctly Orwellian. The book hit No. 6 on the list on Monday and reached No. 1 Tuesday night, reports the Telegraph, which notes Conway's comments inspired social media users to share 1984 quotes including: "The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command." The AP reports that Sinclair Lewis' 1935 novel about an authoritarian president, It Can't Happen Here, is at No. 46 on Amazon's list, with Aldous Huxley's Brave New World at No. 71 and Hannah Arendt's The Origins of Totalitarianism also performing strongly.

motivated by recent experiments on interacting cold atoms , we analyze interaction quenches in luttinger liquids ( ll ) , where the interaction is ramped from zero to a finite value within a finite time .
the fermionic single particle density matrix reveals several regions of spatial and temporal coordinates relative to the quench time , termed as fermi liquid , sudden quench ll , adiabatic ll regimes , and a ll regime with time dependent exponent .
the various regimes can also be observed in the momentum distribution of the fermions , directly accessible through time of flight experiments .
most of our results apply to arbitrary quench protocols .
non - equilibrium dynamics and strong - correlation phenomena in quantum many body systems are topics at the forefront of contemporary physics . when these two fields are combined , namely when strongly correlated systems are driven out - of - equilibrium , we face a real challenge . experimental advances on ultracold atoms
@xcite have made the time dependent evolution and detection of quantum many - body systems possible , and in particular , quantum quenching the interactions by means of a feshbach resonance or time dependent lattice parameters has triggered enormous theoretical @xcite and experimental @xcite activity .
luttinger liquids ( ll ) are ubiquitous as effective low - energy descriptions of gapless phases in various one - dimensional ( 1d ) interacting systems @xcite . in 1d fermions , e.g. , landau s
fermi liquid description breaks down for any finite interaction , and the low - energy physics is described by bosonic collective modes with linear dispersion , and is characterized by anomalous non - integer power - law dependences of correlation functions .
the ll similarly arises as the low - energy description of interacting 1d bosons or that of spin chains @xcite .
a ll could also be driven out of equilibrium through transport @xcite , e.g. , but here we shall concentrate on time dependent changes of the interaction parameter , which is of particular relevance for cold atomic systems .
sudden quenches ( sq ) of the interaction in lls have been considered recently by several authors @xcite , and the idea of the other extreme limit of adiabatic parameter ramps is often invoked , too .
however , experimental ramps can not take infinite time , and are not instantaneous , either .
here we study , how a nonzero quench time , @xmath0 , influences the final state of the system after a quantum quench . as we show
, a finite @xmath1 leads to ` heating ' effects , and generates excitations in the final state .
moreover , it amounts in the appearance of additional energy ( @xmath2 ) and corresponding length scales : while in certain space - time regions the system reveals universal near - equilibrium ( adiabatic ) correlations @xcite , in other regimes renormalized fermi liquid ( fl ) or sudden quench ( sq ) behavior is found .
thus motivated , let us study the ll hamiltonian@xcite @xmath3 , \label{hamilton}\ ] ] with @xmath4 ( @xmath5 being the bare `` sound velocity '' ) , and @xmath6 the creation operator of a bosonic density wave .
the interaction @xmath7 is changed from zero to a nonzero value within a quench time @xmath1 , @xmath8 , with @xmath9 encoding the explicit quench protocol , and satisfying @xmath10 and @xmath11 is assumed . ] . in particular , for a linear quench , @xmath12 with @xmath13 the heaviside functions .
this setting is very general , and equally applies to switching on the interaction in a spinless fermion system , quenching away from the tonks - girardeau limit of a 1d bose gas @xcite , or turning on the @xmath14-component of the interaction in an @xmath15 spin chain@xcite . to make contact with previous work @xcite
, here we focus on fermionic correlators in detail , but most of our results can be trivially generalized to interacting bosonic systems@xcite .
we describe time - evolution using the heisenberg equation of motion , leading to @xmath16= \omega(q)\;b_q+g(q , t)\;b^+_{-q } , \label{heisenberg } % i\partial_t b^+_{-q}=-\omega(q)b^+_{-q}-g(q , t)b_{q},\end{gathered}\ ] ] and similarly , @xmath17 .
solutions of these are of the form @xmath18 where all the time dependence is carried by the prefactors , @xmath19 and @xmath20 , and the operators on the r.h.s
. refer to non - interacting bosons before the quench .
all expectation values are thus taken in terms of the initial density matrix of the latter ( or vacuum at @xmath21 ) .
the bosonic nature of the quasiparticles requires @xmath22 . from eqs . -
, we obtain @xmath23=\left[\begin{array}{cc } \omega(q ) & g(q , t)\\ -g(q , t ) & -\omega(q ) \end{array}\right ] \left[\begin{array}{c } u(q , t)\\ v(q , t)\end{array}\right ] , \label{beq}\end{gathered}\ ] ] with the initial condition @xmath24 , @xmath25 .
since both @xmath26 and @xmath27 are even functions of @xmath28 , @xmath19 and @xmath20 must be so , too . by eq .
, all time dependence has been transferred to the bogoliubov coefficients , and therefore expectation values of the time dependent bosonic modes and non - equilibrium dynamics are calculable using standard techniques developed for equilibrium @xcite , once the solutions of eq . are known . before discussing a continuous quench ,
let s see how limiting cases are recovered from eq . .
the adiabatic limit follows from replacing @xmath27 with its time independent final value , and looking for the stationary solutions of eq . at a given energy while ignoring the initial conditions .
the sq limit requires only the replacement of @xmath27 by its final , time independent value , and solving the resulting linear differential equation with the initial conditions satisfied . with a linear quench , eq .
realizes the non - hermitian landau - zener model @xcite , which can be solved exactly in terms of the parabolic cylinder function .
however , the exact solution does not yield an immediate and transparent physical picture .
therefore , to obtain more insight , we assume that @xmath29 ( i.e. , @xmath30 ) for all @xmath31 and @xmath28 , and solve eq .
perturbatively in the interaction .
to lowest order in @xmath32 , we obtain @xmath33 and @xmath34 higher order corrections to @xmath19 and @xmath20 are of order @xmath35 and @xmath36 , respectively .
we have also checked numerically that eq .
is indeed applicable for any @xmath31 and @xmath1 , as long as @xmath30 for a linear quench . ] . in the sq ( @xmath37 ) and adiabatic ( @xmath38 )
limits we obtain @xmath39 reproducing to lowest order in @xmath32 the sq results @xcite and the equilibrium bogoliubov transformation @xcite , respectively .
we are now in position to obtain information about physical observables .
we start with the evolution of the total energy of the system .
we take the energy of our initial vacuum state to be zero . in the fermionic
setting , this corresponds to measuring the energy with respect to the energy of the non - interacting fermi sea .
the expectation value of eq .
is then evaluated in the heisenberg picture , where the expectation value is taken with the non - interacting ground state , and @xmath20 and @xmath19 as obtained from eq . keeping track of the time evolution of the system .
we thus obtain for @xmath40 after the quench ( @xmath41 ) @xmath42\ ; , % \langle h\rangle=2\sum_{q\neq0 } \left[\omega(q)n_b(q)+(2n_b(q)+1)\times\right.\nonumber\\ % \times\left.\left(\omega(q)|v(q , t)|^2+g(q , t)\textmd{re}[u(q , t)v^*(q , t)]\right)\right ] , \nonumber\end{gathered}\ ] ] with @xmath43 the bose function . the expression above is time independent for @xmath44 , as expected . at @xmath21 and @xmath44 , and an interaction of finite range , @xmath45 ,
we obtain @xmath46\;\end{gathered}\ ] ] for a linear quench . here
we introduced the microscopic time scale , @xmath47 , and @xmath48 is the adiabatic ground state energy shift to lowest order in @xmath49 , with @xmath50 the system size .
the second term corresponds to quasiparticle excitations resulting from the finite quench speed . in the sq limit ,
@xmath51 , the energy of the system is only slightly shifted@xcite , @xmath52 .
this holds true for a general quench , i.e. @xmath53 when @xmath37 with a quench dependent coefficient . in the adiabatic limit , @xmath54 ,
on the other hand , the excess energy ( or `` heating '' ) vanishes as @xmath55 in accord with the so - called analytic response of ref .
@xcite .
this remains valid for general smooth quenches displaying kink(s ) ( discontinuity in the derivative ) and bounded @xmath56 .
smooth quenches without kinks but with bounded @xmath56 produce also a universal decay as @xmath57 , while the @xmath1 dependence of the heating becomes non - universal for protocols with a diverging @xmath56@xcite .
the crossover between the sq and adiabatic limits occurs when @xmath58 , which typically translates to @xmath59 in an optical lattice , with @xmath60 the hopping integral in the underlying microscopic lattice hamiltonian . in the fermionic context
, the structure of the non - equilibrium dynamics can be well demonstrated by means of the fermionic one - particle density matrix .
since the fermion field decomposes to right - going and a left - going parts , @xmath61 , it is enough to concentrate on the right - going part of the density matrix , @xmath62 describing excitations around the right fermi momentum , @xmath63 .
the right - going field , @xmath64 , can be expressed in terms of the ll bosons as @xcite @xmath65 where @xmath66 denotes the klein factor , and @xmath67 . following standard steps @xcite
, we obtain then @xmath68\right ) , \label{greenboson}\end{gathered}\ ] ] where @xmath69 denotes the free fermion propagator , with @xmath70 an ultraviolet regulator . at @xmath21 ,
the bose functions vanish , and only @xmath20 , i.e. the mixing between @xmath71 and @xmath72 determines the dynamics .
let us first discuss the properties of @xmath73 long after the quench , @xmath74 . in this limit
, we can show @xcite that , independently of the quench protocol , @xmath9 , the one - particle density matrix exhibits universal properties , @xmath75 where @xmath76 and @xmath77 denote the perturbative sudden quench and adiabatic exponents , respectively .
the prefactor @xmath78 depends on the speed of the quench : for a sudden quench it is @xmath79 , while for slower quenches @xmath80 . thus even for @xmath81 , instead of one single power - law , @xmath82 interpolates between the sq and adiabatic limits
this is shown in fig .
[ figdensitymatrix ] for a linear quench@xcite .
physically , it is easy to understand the cross - over behavior observed in @xmath82 : a finite - time quench is experienced by slow excitations of energy @xmath83 as a sudden change , while fast excitations with @xmath84 can adjust to the change in the interaction strength adiabatically . since high
( small ) energy excitations determine the short ( long ) distance correlations , the tail of @xmath82 is governed by the sq exponent @xcite , while the short distance behavior is described by the adiabatic exponent .
it is remarkable that for slow enough quenches , @xmath85 , the quench time manifests itself explicitly through an adiabatically _ enhanced _
prefactor @xmath86 of the asymptotic tail as also shown in fig .
[ figdensitymatrix ] .
thus while the spatial decay of eq
. contains the sq exponent , its @xmath1 dependence reveals the adiabatic ll exponent . for a finite @xmath87 but @xmath88
, @xmath73 decays asymptotically as @xmath89 , with a finite quasi - particle weight , @xmath90 thus the exponent observed in @xmath91 is identically @xmath92 for @xmath74 , but the finite quench time amounts in a quasiparticle weight increased by a factor , @xmath86 for @xmath85 .
although these results were obtained perturbatively , they carry over to the non - perturbative limit , too , with the only exception that the exponents @xmath92 and @xmath93 must be replaced by their exact value .
all these spatial features appear also in the time - dependent momentum distribution of the fermions , @xmath94 , directly measurable through time of flight experiments .
in particular , at @xmath21 and finite @xmath74 , @xmath94 exhibits a jump of size @xmath95 at @xmath96 , while it approximately scales for @xmath97 as @xmath98 for @xmath99 , @xmath100 , and @xmath87 .
thus the time scale of the quench is also imprinted in the momentum distribution , which also shows a cross - over behavior between the sq and the adiabatic limits . for adiabatic quenches , @xmath101
, we recover the equilibrium ll exponent , while close to @xmath102 , the momentum distribution is enhanced by a factor @xmath103 compared to the sq behavior@xcite . ) , steady state limit of the one - particle density matrix is plotted on loglog scale for a linear quench and @xmath104 as a function of @xmath105 , exhibiting the crossover from adiabatic behavior ( lower line in eq . ) at small @xmath105 to sq behavior with adiabatic enhancement ( upper line in eq . ) at large @xmath105 .
the curves are plotted for @xmath106 , @xmath107 and @xmath108 from bottom to top in both panels .
right : landau s quasiparticle weight , @xmath91 is plotted on a loglog scale as a function of @xmath31 , bridging between the weakly interacting fermi liquid to strongly suppressed @xmath109 with adiabatic enhancement ( eq . ) .
inset : the linear quench protocol is shown .
[ figdensitymatrix],title="fig:",width=313,height=154 ] the above analysis can be extended to the short time region , @xmath110 , where the behavior found depends explicitly on the quench protocol@xcite as @xmath111 where @xmath112 . for short distances , @xmath113 , the spatial correlations decay with a time - dependent exponent , and this region
can thus be characterized as a weakly interacting ll ( t - ll ) . for @xmath114 , on the other hand , similar to @xmath74 , correlations remain almost unaffected by interaction , and a fermi liquid regime is found . for @xmath115 , @xmath116 as in the initial fermi gas , but for @xmath117 we recover a fermi liquid behavior with a reduced quasiparticle weight as @xmath118 governs spatial correlations , while in the sq ll region , correlations decay with the sq exponent , @xmath119 .
correlations are adiabatically increased by an amplitude , @xmath86 in the shaded region . in the fermi liquid region
a time dependent quasiparticle residue is found ( see eq . ) , while in the time - dependent ll ( t - ll ) region a quench protocol - dependent weakly interacting ll is found with a time dependent exponent , eq . .
the dashed line denotes @xmath120 , i.e. the light - cone@xcite . for @xmath51 , the sq physics of ref .
@xcite dominates everywhere .
[ figphase],title="fig:",width=226 ] the quasiparticle weight thus slowly decreases during the quench , and excitations remain similar to those in the initial fermi gas with a reduced weight ( @xmath121 ) for @xmath122 . after the quench , @xmath44 , the quasiparticle weight continues to decrease as a power - law , and it resembles to an interacting ( heavy ) fermi liquid with @xmath123 spatial decay and @xmath109 quasiparticle residue , eq .
, as was also found for sudden quenches @xcite .
this situation is shown in detail in fig .
[ figdensitymatrix ] , where @xmath91 is plotted for the special case of a linear quench@xcite .
our results are summarized in fig .
[ figphase ] . the main effect of finite temperatures ( @xmath124 ) in eq .
is to introduce a new time or length scale , @xmath125 or @xmath126 , respectively , above which the power law behaviour of ll disappears , and gives way to exponentially suppressed behaviour as @xmath127)$ ] with @xmath128 some constant .
our findings in fig .
[ figphase ] survive in the region @xmath129 .
ultracold fermionic gases have been realized using several atoms such as @xmath130k@xcite , @xmath131li@xcite , @xmath132yb-@xmath133yb@xcite , @xmath134dy@xcite and @xmath135sr@xcite , and temperatures well in the quantum degeneracy regime were reached ( @xmath136 , with @xmath137 the fermi energy ) .
all these atomic systems feature tunable interactions , essential to address quench dynamics . among these
, 1d configurations have been realized using @xmath130k@xcite , @xmath131li@xcite , and the momentum distribution has been measured in time of flight ( tof ) experiments in 2d@xcite and 3d@xcite fermi gases . therefore , by applying tof imaging or momentum resolved rf spectroscopy@xcite , the observation of the momentum distribution of eq .
is within reach for 1d fermions @xcite .
furthermore , the specific momentum distribution of a ll has already been observed in the tonks - girardeau limit of 1d bose systems@xcite , which exhibit fermionic properties in this strongly interacting regime , and reveal after an interaction quench features similar to the ones found for fermions @xcite . in summary , we have studied continuous interaction quenches in ll , bridging smoothly between the sq and adiabatic limits .
the resulting dynamics is largely influenced by the finite quench time for fermions , and in particular , the momentum distribution exhibits a crossover from the adiabatic ll to that of the sq with the extra adiabatic enhancement factor @xmath138 , revealing _ both _ the equilibrium and sq ll exponents .
a finite quasiparticle residue is retained during the quench , reflecting the fermi gas nature of the initial state , getting suppressed gradually after the quench .
the variety of quench induced phases offers a unique opportunity to design low dimensional correlated states on demand .

– A tourist and trainer have died after a walrus "hug" at a wildlife park in China. A male tourist from northern China was reportedly taking videos of a walrus from a narrow walkway at Xixiajou Wildlife Park in Shandong Province when he accidentally fell in the walrus pool. A trainer jumped in after him but a 3,000-pound walrus wrapped the pair in a "hug" and pulled them underwater, per the Shanghai Daily. Onlookers attempted to use bamboo poles to free the men, but both had drowned by the time they were recovered from the pool. The accident occurred "lately," though a precise date wasn't given. The New York Post reports a "disturbing" video of the incident has appeared on social media site Weibo. The video, along with photos of the walrus pool, have many questioning whether the site is safe for visitors, who observe the pool from what is essentially an elevated sidewalk that has no railing or other barrier. The park remains open, and employees say the walrus involved is usually docile and may have only been trying to play with its longtime trainer.

There's no evidence to support it was an attack and the walrus might be just trying to get the humans to play with it, local media reported. The tourist accidentally fell into the walrus pool at the Xixiakou Wildlife Park in Rongcheng city and the walrus keeper, surnamed Duan, immediately plunged into the water trying to save him, Modern Express reported today. The incident was reported to have happened lately without being specified with an exact date, according to the report. But they were too weak to escape the 'hug' by the giant animal, weighing more than 1.5 tons. The incident ended with the walrus pulling them both to the deep waters. Other workers reportedly had tried driving the walrus away with bamboo poles but failed. The duo were already dead when they were finally pulled up. The animal keeper, Duan, had been looking after the walrus, aged more than 10 years old, for a long time and was said to have well bonded with the walrus, said the other workers. The walrus probably just wanted to have somebody to play with underwaters, said the workers. The killer walrus was said to have a mild temper and loves playing with humans much, the workers said. There is no banister at all to prevent tourists from falling into the pool while the walkway above the pool is also narrow, according to the report. ||||| A 3,300-pound walrus killed two people in a Chinese wildlife park by “hugging” them tightly and drowning them, according to reports.

The animal’s longtime trainer jumped in the water to try to save the flailing visitor — but the massive pinniped wrapped its arms around both men and plunged the pair deep underwater.

– That hair-hanging-over-the-eye style so popular with Justin Bieber wannabes and emo kids alike may not be such a great idea: An expert described by Australia’s Daily Telegraph as a “leading optometrist” claims the haircut could cause amblyopia, commonly known as lazy eye. "If a young emo chap has a fringe covering one eye all the time, that eye won't see a lot of detail," says Andrew Hogan, a national executive member of the Optometrists Association. "And if it happens from a young age, that eye can become amblyotic." "If you walk around with an eye patch on all day, then that eye will end up seeing more poorly than the other eye," he adds. And if the hair-eyepatch limits access to sunlight, it may also result in short-sightedness. A “veteran hairdresser” adds that the hairstyle could also cause posture problems, since it forces kids to tilt their heads to one side. "I have to wonder how they don't get a stiff neck," she says. Amusing as this story is, an opthamologist bluntly dismisses it, telling TVNZ such concerns are “silly.” | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | No fringe benefits for emos as haircuts that flop over one eye could result in generation of young people with lazy eyes UNDER all those long lopsided fringes, a hidden danger is lurking. A leading optometrist has warned children and teenagers are risking their eyesight for the sake of fashion. Favoured by celebrities including Reece Mastin and Justin Bieber, the current zeal for haircuts with fringes that flop over one eye could result in a generation of young people with lazy eyes. Photos: Reece Mastin Photos: Justin Bieber Optometrists Association national executive member Andrew Hogan warned amblyopia - the medical term for lazy eye - could result from obstructed vision caused by hair. "If a young emo chap has a fringe covering one eye all the time, that eye won't see a lot of detail," Mr Hogan said. "And if it happens from a young age, that eye can become amblyotic." Mr Hogan said the most vulnerable age for visual development was birth to seven years, but research had shown vision could still be affected at later stages. As well as the potential damage to eyesight, there are also concerns that long "emo" sweep fringes could cause postural problems. Veteran hairdresser Roseanne Anderson fears the hairstyle forced many to tilt their heads to one side in order to see out of their small window of vision. "I have to wonder how they don't get a stiff neck," the Hobart-based hairdresser said. "I have seen lots of fashions come and go - but really when I think about it, this is probably the only hairstyle in my 40 years of hairdressing that could be a health hazard." Mr Hogan said a curtain of hair over one eye could actually act like an eyepatch, limiting the eye's access to both sunlight and sensory stimulation. He said recent research had shown a lack of direct sunlight resulted in short sightedness. And hair constantly hanging over one eye could result in sensory deprivation that could weaken one eye and lead to amblyopia. "If you walk around with an eye patch on all day, then that eye will end up seeing more poorly than the other eye," he added. Amblyopia occurs when the nerve pathway from one eye to the brain does not develop because the abnormal eye sends a blurred image to the brain. ||||| Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive.

– The Vatican may have arrested the pope's butler, accusing him of being the source of the ongoing leaks of confidential and personal documents to the Italian press, but he is actually just a scapegoat—according to the latest leak of confidential documents, reports MSNBC. The Italian newspaper Il Repubblica wrote yesterday that it received a letter and three other documents—after the butler's arrest—which starkly reveal the Game of Thrones-esque intrigue going on in the Vatican, and Pope Benedict's lack of control over the chaos. A letter by the apparent leaker said butler Paolo Gabriele was the "usual scapegoat," and that the true purpose of the leaks was to "drive out the real culprits from the Vatican," meaning the pope's personal aide, Georg Gaenswein, and Cardinal Tarcisio Bertone, the secretary of state. The letter also claimed to have 300 more documents on the way. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Alessandro Bianchi / Reuters file Paolo Gabriele, Pope Benedict XVI's butler, is accused of leaking documents alleging Vatican corruption, but new documents published Sunday— after his arrest last month — suggest he may be a scapegoat. Pope Benedict XVI's butler, who is under arrest for allegedly leaking confidential Vatican documents, is just a scapegoat, according to the source of new secret documents published Sunday by the Italian newspaper La Repubblica. The butler, Paolo Gabriele, 45, remains in a Vatican jail cell on charges of aggravated theft for possessing confidential correspondence. Publication of the new documents Sunday — which La Repubblica said it had received from an unknown person after Gabriele's arrest on May 25 — would strongly indicate that Gabriele wasn't the only person with access to the secret correspondence of the Roman Catholic Church. The documents lay bare the political machinations among cardinals posted to the Vatican, suggesting an administration riven by infighting over which Benedict, 85, has — or chooses to exercise — little authority. In a letter accompanying the three new documents, the shadowy provider calls Gabriele "the usual scapegoat" and says his or her intention is to "drive out the real culprits from the Vatican," whom the letter identifies as Msgr. Georg Gaenswein, Benedict's personal secretary, and Cardinal Tarcisio Bertone, his secretary of state. The source warns that the new papers are just "three of the hundreds of documents in our possession" that could be damaging to the Vatican. The documents published Sunday include two written on Gaenswein's personal letterhead. The text, however, had been whited out — a step the source said he or she had taken to protect the pope. In the accompanying cover letter, the source says the documents prove that Benedict is being served by an "inept staff." Gaenswein has greatly increased his influence in the Vatican in recent years, according to La Republicca, and is one of the pope's closest confidants. The letters, if authenticated, could suggest that even the most sensitive Vatican documents have been compromised. The third document is a letter to Bertone from Cardinal Raymond Leo Burke, an American who is head of the Supreme Tribunal of the Apostolic Signatura — in essence, the Vatican's chief justice. It is marked "highly confidential" and registers Burke's dismay that Benedict had approved the liturgy of a controversial lay group known as the NeoCatechumenal Way, which its critics contend violates the prescribed protocol for the Catholic Mass. "I believe that approval of such liturgical innovations ... does not seem consistent with the liturgical teachings of the Pope," Burke wrote. More world news from msnbc.com and NBC News: |

– One of Steve Jobs' quirks was that he always a drove a car without license plates. But just how did he get away with it? The surprisingly simple answer, from Gizmodo via iTWire: California law allows you to drive a new car for six months without plates. So every sixth month, Jobs would turn in his silver Mercedes-Benz and lease a brand-new one of the same model. "It's a hilariously logical rich man way of thinking to sidestep the law," writes Gizmodo's Casey Chan. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | We've always wondered why Steve Jobs' Mercedes-Benz SL55 AMG didn't have a license plate. Did he think he was above the law? Was he doing it to be different? Maybe! But how did he get away with it? Easy. His cars were leased. According to Jon Callas, CTO of Entrust, and someone who has done senior security roles for Apple before, Steve Jobs found a loophole of sorts in California license plate laws. If you had a new car, you could drive plateless for 6 months (of course, you still had to register). So Jobs, being rich beyond belief, decided he would just lease a new car every 6 months. He came to terms with a leasing company and switched out his 'old' Mercedes SL55 AMG for a 'new' Mercedes SL55 AMG twice a year. Advertisement It's a hilariously logical rich man way of thinking to side step the law. Or a crazily convoluted way to stay different. [iTWire via Jalopnik] You can keep up with Casey Chan, the author of this post, on Twitter or Facebook. ||||| iTWire had the good fortune this morning to spend an hour with Jon Callas, CTO of Entrust, who in the past worked two stints at Apple in various senior security roles.Amongst other tales around his time at Apple, we couldn't resist asking if Callas knew anything about the number plate saga. Of course he did - and here it is.It turns out that Steve quite liked the idea of being different (recall the "think different" slogan so regularly used by Apple) and discovered a perfectly legal way to permanently drive without a number plate.Some outlets have suggested that he doesn't care and will happily pay a fine if ever confronted by police; others , quoting Steve Wozniak, suggest that he had some kind of permit to do so.Neither is true. In fact the truth is far simpler.Steve (or someone close to him) spotted a loophole in the California vehicle laws. Anyone with a brand new car had a maximum of six months to affix the issued number plate to the vehicle.So Jobs made an arrangement with the leasing company; he would always change cars during the sixth month of the lease, exchanging one silver Mercedes SL55 AMG for another identical one. At no time would he ever be in a car as old as six months; and thus there was no legal requirement to have the number plates fitted.One might also assume that the leasing company was happy - they had an endless supply of luxury cars to on-sell with the previous driver being none-other that Steve Jobs.That would be a win-win-win situation for Steve, the leasing company and for the subsequent buyer. |

– Frito-Lay is getting in on New York City's "Restaurant Week" (which is really more like "Restaurant Month") by opening a pop-up eatery with a menu full of Cheetos-themed cuisine. The Spotted Cheetah opens its doors in lower Manhattan for just three days next week, starting on Tuesday and ending Thursday, the AP reports. Some of the dishes on the three-course menu created by chef Anne Burrell include Cheetos Crusted Fried Pickles, Mac n' Cheetos, and Cheetos Sweetos Crusted Cheesecake. Prices run from $8 to $22 per dish. Frito-Lay says recipes created by fans inspired the company to "bring a full Cheetos culinary experience to life." "As a longtime Cheetos fan, I'm thrilled to join forces with a snack brand that is truly an iconic American staple," Burrell says in a press release. CNNMoney notes that a handful of fast-food eateries have "flirted" with menu items based on the orange snack before, but this appears to be the first time an entire menu has been inspired by it. The Spotted Cheetah is completely booked for its brief run that begins Tuesday, but Cheetos fans can add their names to an online waitlist. A cookbook based on the restaurant's offerings will also be posted online. Plano, Texas-based Frito-Lay is a division of PepsiCo. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

Cheetos, the snack chip owned by PepsiCo (PEP), is launching a pop-up restaurant in New York City devoted to Cheetos-inspired dishes. The Spotted Cheetah, which opens to the public between August 15 and August 17, is a marriage between Cheetos and celebrity chef Anne Burrell. Burrell has worked at several high-end New York restaurants, is an author of popular cookbooks and host of culinary shows, Chef Wanted, Worst Cooks in America and Secrets of a Restaurant Chef. "As a long-time Cheetos fan, I'm thrilled to join forces with a snack brand that is truly an iconic American staple," Burrell said in a press release. "I had so much fun curating this specially crafted, one-of-a-kind menu for the first Cheetos restaurant -- I can't wait to see guests' reactions!" The all-Cheetos menu will feature dishes that range from $8 to $22, such as Flamin' Hot and White Cheddar Mac n' Cheetos. Cheetos fans in recent years have infused their innovation into Cheetos-inspired food and shared recipes online. It was their creativity that inspired the pop-up, according to Ryan Matiyow, senior director of marketing of Frito-Lay, the Pepsi (PEP) division that makes Cheetos. "The Spotted Cheetah is a fun and delicious way for Cheetos to celebrate a variety of favorite flavors in an upscale and playful culinary setting that will wow our guests," Matiyow said. Fast food restaurants have flirted with Cheetos-inspired menu items in the past. Burger King twice added "Mac n' Cheetos," deep-fried macaroni and cheese sticks covered with Cheetos flavoring, to its menu. Yum! Brands (YUM)' Taco Bell launched Cheetos Quesadillas in the Philippines, and was said to be testing out Cheetos burritos last year. The Spotted Cheetah marks the first time an entire menu is based on the snack. Reservations for the New York pop up begin Tuesday. A cookbook that features the menu items from the restaurant will be available online. |

magnetic and spin - based technologies for data storage and processing pose unique challenges for information transduction to light because of magnetic metals optical loss , and the inefficiency and resistivity of semiconductor spin - based emitters at room temperature@xcite .
transduction between magnetic and optical information in typical organic semiconductors poses additional challenges as the faraday and kerr magnetooptical effects rely on the electronic spin - orbit interaction@xcite , and the spin - orbit interaction in organics is weak@xcite
. other methods of coupling light and spin have emerged in organics , however , as the spin - dependent character of exciton recombination , with spin injection from magnetic electrodes , provides magnetization - sensitive light emission@xcite , although such approaches have been limited to low temperature and low polarization efficiency@xcite . here
we demonstrate room temperature information transduction between a magnet and an organic light emitting diode that does not require electrical current , based on control via the magnet s remanent field of the exciton recombination process in the organic semiconductor .
organic semiconductor devices have become a ubiquitous lighting technology due to their flexibility , inexpensive character , and highly efficient light output .
organic information processing also has an important niche where computational speed is less important than flexibility or expense .
nonvolatile information storage in organic electronics poses a challenge , as organic semiconductor flash memory currently have high leakage currents due to the large electric fields required to change transport properties in organic semiconductors@xcite .
the non - volatility , speed , and low energy consumption of magnetic memory make it fundamentally attractive for integration with organics although magnetic metals have large impedence mismatches with organics .
this can be overcome using coupling through a magnet s fringe field at zero applied field ( remanent field ) as demonstrated in organic electronic devices@xcite .
efficient coupling via the magnet s remanent field between light emission in organic devices and a magnetic memory would broaden the range of applicability of flexible , inexpensive organic electronics .
our demonstration of efficient room - temperature coupling between an organic light - emitting diode and a few - nanometer - thick magnetic film can be explained quantitatively within a theory of spin - dependent exciton recombination in the organic semiconductor , influenced only by the remanent fringe fields of the magnetic material .
organic semiconductor sandwich devices , used for example in organic light - emitting diodes ( oleds ) , consist of a thin film of an organic semiconductor ( or several layers thereof ) sandwiched between a bottom and top electrode .
the organic semiconductor is typically intrinsic , and is essentially void of charge carriers .
therefore one of the electrodes is chosen to efficiently inject electrons , and the other to efficiently inject holes .
for this purpose low and high - work function metals , respectively , are chosen .
recombination of electron - hole pairs leads to electroluminescence , as shown in fig .
[ fig : mainexperimentalfigure]a .
transport of the injected carriers through the organic film occurs via a sequence of hops along a path connecting the top electrode to the bottom electrode , and the rate of transport and/or recombination is dramatically affected by variations in the local magnetic field along the path , as found in numerous experimental and theoretical studies @xcite . in the transport regime , this effect is known as organic magnetoresistance ( omar ) , and the corresponding effect in the electroluminescent output we will denote as organic magnetoelectroluminescence ( omel ) .
typically the source of that inhomogeneous field is the nuclear hyperfine field , which is random and spatially uncorrelated .
the origin of omar can be traced back to interactions between paramagnetic charge pairs that occur at bottle - neck sites ( sites that crucially affect the transport and/or electroluminescent properties ) .
these interactions are often spin - selective , and the reaction rate depends on the angle between the local spin - quantization axis ( provided by the local magnetic field ) for the two paramagnetic species .
an applied magnetic field exceeding the hyperfine field strength forces this angle to be close to zero everywhere in the film , which shows up as magnetoconductance ( mc ) and/or magnetoelectroluminescence ( mel ) with typical features like those in fig .
[ fig : mainexperimentalfigure]b .
large gradients in the magnitude of the random local field can lead to fringe - field - driven mc and mel , and devices were constructed that utilize fringe fields from an unsaturated magnetic film to supply such gradients @xcite .
this paper will primarily discuss such fringe - field effects , but `` ordinary '' omar and omel ( based on , _ e.g. _ , hyperfine fields ) is also investigated as a reference .
the exact nature of the paramagnetic pairs remains hotly debated , and the possibilities include electron - hole pair recombination to form singlet or triplet excitons @xcite , @xmath0 or @xmath1 recombination to form singlet bipolarons @xcite , and collision reactions between electrons or holes with long lived triplet excitons @xcite .
as the fringe - field mel mechanism is driven by fringe - field gradients , independent of the mechanism of ordinary omar and omel , the effects presented here should be found in organic materials independent of the mechanism of omar and omel , including in materials where there is no omar and omel@xcite . as shown in fig .
[ fig : mainexperimentalfigure]*a * our devices are omar / oled devices fabricated on top of a ferromagnetic thin film .
the device fabrication starts with the metal deposition of a ferromagnetic multilayered thin film made of cobalt ( co ) and platinum ( pt ) .
those films have perpendicular magnetic anisotropy ; the spins tend to align in the direction orthogonal to the film plane . in presence of a large magnetic field out of the film plane
the co@xmath2pt films are uniformly magnetized with all the spins pointing opposite to the direction of the applied field . at lower fields the films form magnetic domains some regions with spins pointing up and others with spins pointing down to lower the magnetostatic energy .
these magnetic domains create strong varying fringe fields close to the surface of the co@xmath2pt films , which penetrate the omar / oled device . in order to electrically insulate the omar / oled device from the ferromagnetic film we deposit a thin dielectric followed by a conductive nonmagnetic layer on top of the magnetic film .
these electrically insulated magnetic films prove that fringe fields and not electrical currents are responsible for the coupling between the ferromagnetic layer and the omar / oled device .
however , the strength and spatial correlation length of magnetic fringe fields depend sensitively on the distance from the magnetic film to the organic film .
the insulating layer increases this distance reducing the effect . as a result
we report results primarily on devices without this layer , which show the largest effects , and study devices with insulating layers to rule out spin injection and tunneling anisotropic magnetoresistive devices . a conducting polymer layer ( 20 nm ) of poly(3,4-ethylenedioxythiophene ) poly(styrenesulfonate ) ( pedot : pss , referred to as simply pedot from now on ) was spin - coated from water suspension and serves as the hole - injecting layer .
pedot is commonly employed for this purpose in organic light - emitting diode devices.@xcite we chose poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene ] ( mehppv ) as the luminescent polymer , as it is widely used as a red emitter in oleds@xcite .
the mehppv layer ( 55 nm ) was deposited by spin - coating from toluene solution .
finally , calcium ( ca ) ( 6 nm , serving as the electron - injecting top contact ) covered by aluminum ( al ) ( 12 nm ) was deposited by vacuum evaporation through a shadow mask .
the active device area is roughly 1 mm@xmath3 .
the al capping layer is required to protect the highly reactive ca layer .
the contributions of the pedot and ca electrodes to the device resistance ( and magnetoresistance ) are negligible , since they are metals , whereas mehppv is an intrinsic semiconductor .
the el is measured through the semitransparent top electrode , and recorded by a photomultiplier tube .
all measurements reported here are at room temperature . figure [ fig : mainexperimentalfigure]*b * shows a typical mc and mel trace , and fig .
[ fig : mainexperimentalfigure]*c * the iv and el curves , for an organic device without a magnetic film and whose mc / mel is therefore caused by the random hyperfine fields , as described above .
this device will serve us as a reference when , later on , we will discuss fringe - field induced mc / mel .
it is seen that the hyperfine induced mc and mel responses have a magnitude of @xmath4 5 % and @xmath4 10 % , respectively , in our mehppv devices .
the effects essentially saturate for applied fields in excess of 0.1 t , are non - hysteretic , and have a full - width - at - half - maximum of approximately 20 mt .
the effects are also independent of the direction of the applied magnetic field , and nearly independent of the mehppv layer thickness . in the present work
, we have chosen to work with a thin mehppv layer ( 55 nm ) such that the distance from the ferromagnetic film does not vary much between different locations in the mehppv film .
now we turn our attention to the mc / mel responses of the fringe - field omar devices , and the correlation between these effects and the film magnetization , @xmath5 .
figure [ fig : mainexperimentalfigure]*d * shows the measured mc and mel curves , and * e * shows the magnetization loop measured by magneto - optic kerr effect ( moke ) ( see methods section ) . in these measurements ,
the magnetic field is applied perpendicularly to the device plane , and is swept smoothly from large negative to large positive fields ( black lines ) and back ( red lines ) .
it is seen that the magnetization response is hysteretic , and that @xmath5 assumes its saturation value @xmath6 for fields larger than approximately 0.25 t in magnitude .
@xmath5 is unsaturated between roughly @xmath7 and @xmath8 t. the mc / mel curves outside the unsaturated magnetization regime clearly mirror the data in non - magnetic devices ( panel * b * ) , and are explained by the `` normal '' hyperfine omar effect . in the unsaturated region ,
the data curves develop characteristic `` ears '' .
these are the signature of fringe - field effects .
we have previously given a detailed experimental and theoretical characterization of the transport aspect of this effect.@xcite in the present work , we demonstrate for the first time that fringe - field effects lead to a sizable room - temperature mel response , of up to 6% at room temperature for the present device .
this can be comparable to mel effects that occur only at low temperature , such as those recently reported in spin - valves@xcite and high - magnetic - field effects for oleds@xcite .
next we examine the relation between the magnetic film s response characteristics and mc / mel by fabricating omar / oled devices on several different ferromagnetic electrodes . in this work ,
the different magnetic responses are studied by fabricating ferromagnetic films consisting of cobalt ( co ) and platinum ( pt ) multilayers with a different number of repeats , @xmath9 .
we studied devices with @xmath10 @xmath11 , @xmath12 and 30 ( film thicknesses varied from 4 nm to 24 nm ) .
the magnetization in the ferromagnetic films reverses through nucleation , growth , and annihilation of magnetic domains . when the magnetic films are saturated ( all spins pointing towards the same direction ) there are no magnetic fringe fields on top .
when the magnetic films are unsaturated the strength of the magnetic fringe fields created by magnetic domains increases ( almost linearly ) with the thickness of the ferromagnetic layer ( i.e. , with the number of repeats ) .
properties of co@xmath2pt ferromagnetic films have been characterized in detail ( see refs . and ) .
the data of fig .
[ fig : dependenceonrepeats ] shows that the hysteretic magnetoresistance of the organic layer is directly correlated with the hysteretic magnetization of the ferromagnetic film .
the fringe - field `` ears '' occur only in the unsaturated regime , where film s magnetization breaks into domains with fringe fields occurring near the domain boundaries .
figure [ fig : isolateddevice ] shows data similar to that reported in fig .
[ fig : dependenceonrepeats ] , but now for a device with an additional sio@xmath13 layer inserted between the magnetic film and the omar / oled device .
this data exhibits all the same characteristics of the data without the insulating layer , and proves that the coupling between the magnetic film and the organic device is magnetic rather than electrical in nature .
in particular this excludes mechanisms such as tunneling anisotropic magnetoresistance and spin - injection effects as the origin of the observed effects .
the `` ears '' are however significantly smaller in magnitude .
however , this was to be expected , since the insulating layer leads to a significantly larger separation between magnetic film and omar / oled device as the overall spacer layer thickness increases from 20 nm to 45 nm with the layer inserted .
we have previously examined@xcite the dependence of the magnitude of the fringe - field magnetoresistance on the spacer layer thickness .
magnetic domains can be present at zero applied field in our magnetic films .
such remanent states are prepared by applying a perpendicular field close to the film s coercive field and then removing it ( see fig .
[ fig : remanentmel]*a * ) .
magnetization measurements and imaging prove that remanent domain states relax only slightly upon removal of the field .
therefore , we have access to remanent magnetization states ranging from negative to positive saturation . at zero applied field
we observed how remanent fringe fields increase the conductance of the organic layer mehppv , suppressing omar .
the same effect with a smaller strength was observed in the organic semiconductor alq@xmath14@xcite .
figure [ fig : remanentmel]*bd * shows mc and mel of a 55 nm thick mehppv film on top of a magnetic layer both in presence of and at zero magnetic field .
the blue line depicts the measured values in presence of magnetic field whereas the red lines trace the values measured after removing the applied field ( a sketch of the measuring sequence is shown in fig .
[ fig : remanentmel]*a * ) : we first saturated the sample with a large negative field , then we set a positive field value from 0 to 0.3 t and measured the conductivity of the organic layer ( blue points ) , and then we removed the applied field and again measured the organic s conductivity ( red points ) . here
we show that the electroluminiscence increases up to 6@xmath15 for remanent magnetic domain states of the ferromagnetic layer .
in contrast to fringe fields from the same domain configuration in an applied magnetic field ( near the coercive field ) the mel increases rather than decreases .
we now examine whether the large fringe - field effects observed in the mel can be explained by theory .
we consider a two - site model where an electron and hole ( a polaron pair ) occupy two nearby sites .
the spin configuration of the polaron pair undergoes transitions due to the different magnetic interactions present ; in our case these interactions consist of @xmath16 which are the applied , hyperfine , and fringe - field hamiltonians respectively .
the polaron pairs recombine into excitons at different rates , @xmath17 and @xmath18 , depending on the pair s spin since the singlet and triplet states have different energies and wavefunctions@xcite ( see .
schematic fig .
[ fig : mainexperimentalfigure]*a * ) ; alternatively the pair could disassociate at a rate @xmath19 . once an exciton is formed , the large exchange energy precludes any further spin evolution . in the absence of large spin - orbit interactions , spin selection rules
dictate that exciton recombination ( i.e. photon emission ) occurs only from the singlet exciton state . assuming that radiative recombination is the only viable pathway for a newly formed singlet exciton
, each singlet exciton will produce a single photon such that mel can be defined in terms of @xmath20 , the singlet fraction of excitons : @xmath21/x_s(0)$ ] . to calculate the mel we employ the stochastic liouville equation for the polaron pair spin density matrix , @xmath22:@xcite @xmath23 - \frac{1}{2 } \ { k_s p_s + k_t p_t , \rho \ } - k_d \rho,\ ] ] where @xmath24 and @xmath25 are the singlet and triplet projection operators .
the steady - state singlet and triplet exciton fractions are@xcite @xmath26dt,\ ] ] where @xmath27 runs over @xmath28 and @xmath29 .
all rates ( times ) are in units of the hyperfine field frequency ( period ) , @xmath30 ( @xmath31 ) where @xmath32 is the width of the gaussian distribution of hyperfine fields . for simplicity
we assume @xmath33 and @xmath34 . to proceed with the calculation
, one must have knowledge of the fringe fields present in the organic layer . in our previous analysis@xcite on fringe - field
induced magneto - resistance , elementary magnetostatics were used to calculate fringe fields from xmcd images of the magnetic domains .
the samples described herein have the same composition .
we use therefore the statistical analysis from the aforementioned xmcd images to model the fringe - field distributions .
given the fact that fringe fields vanish at magnetic saturation and are largest and most varying at @xmath35 , we model the fringe - field distribution as normal distribution with mean zero and a field dependent standard deviation .
each component of the fringe - field gradient , @xmath36 is modeled likewise .
the field dependent standard deviations follow a parabola defined in the upper half - plane according to @xmath37 @xmath38 where @xmath39 is the field at which the magnet starts developing domains ( obtainable from either the moke data or the mel measurements ) and @xmath40 is the field corresponding roughly to @xmath35 .
@xmath41 and @xmath42 mark the parabola s vertex and are the only free parameters .
however , from analysis of samples of the same composition on which xmcd images have been acquired , their values are roughly 40 mt and 1 mt / nm respectively for a spacer width of 20 nm .
the results of this theory and model are shown in fig .
[ fig : remanentmel]*c*. the @xmath39 and @xmath40 are chosen from figure [ fig : mainexperimentalfigure]*e*. the values of @xmath17(=@xmath43 ) and @xmath18(=@xmath44 ) are chosen to achieve a saturated mel percentage near that of figure [ fig : mainexperimentalfigure]*d * ( @xmath45 ) .
the values for the hopping rates fall into the intermediate hopping regime ( @xmath46 ) which is necessary to have any fringe - field effect .
remanent fringe fields generated from the domain structure of the magnetic film cause the observed dramatic modification of the electroluminescence from an organic light emitting diode at room temperature . as a uniform , perpendicularly magnetized film produces no remanent fields , the source of these fringe fields is the regions where the magnetization changes most rapidly , corresponding to domain walls .
the faster the magnetization changes , or the smaller the domain size , the larger the remanent fields .
thus this approach of interfacing magnetic information encoded in the domain structure with an organic light emitting diode should become more effective and efficient as the magnetic domain sizes shrink .
we note as well that the mel is significantly larger than the mc , indicating that ( for mehppv ) fringe - field optical coupling and readout will have greater sensitivity than fringe - field electrical coupling and readout of magnetic information . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | the organic semiconductor semi - spin valve consists of a ferromagnetic layer , a hole - injecting layer , an organic semiconductor , and a top electrode .the ferromagnetic electrode is a co@xmath2pt multilayer with the number of repeats varied from 4 to 22 deposited using electron - beam evaporation in ultra high vacuum on oxidized si wafers for device studies and si supported si@xmath47n@xmath48 membranes for magnetic domain imaging studies using an x - ray transmission microscope .optical lithography is used to define lines in the ferromagnetic thin film .a hole - injecting layer , conducting polymer poly(3,4-ethylenedioxythiophene ) poly(styrenesulfonate ) ( pedot : pss ) , was deposited by spin - coating from an aqueous suspension ( suspension purchased from h. c. starck , clevio p vp ai 4083 ) . a 55 nm thick film of organic semiconductor mehppv ( purchased from american dye source , inc . )was deposited by spin coating with 3mg / ml solution in toluene . the electron injecting layer , ca ( 6 nm ) covered by al ( 12 nm ) was deposited by thermal evaporation at room temperature through a metal stencil to obtain a cross point device geometry .the ferromagnetic electrodes were characterized by magnetic force microscopy ( mfm ) , ferromagnetic resonance ( fmr ) , vibrating sample magnetometery ( vsm ) , and magneto - optical kerr effect ( moke ) .magnetoresistance measurements were done in a closed - cycle he cryostat positioned between the poles of an electromagnet .the measurements reported here are all at room - temperature .magnetoresistance ( mr ) measurements were performed using a keithley 2400 sourcemeter .electroluminescence was measured by photomultiplier tube through the top electrode ca / al .x - ray measurements were performed at the advanced light source ( als ) at the lawrence berkeley national laboratory .images were taken with xm-1 zone - plate microscope at beamline 6.1.2 .this work was supported by aro muri grant no .w911nf-08 - 1 - 0317 .fm thanks support from eu , mc - iof 253214 .pt multilayers with a different number of co@xmath2pt repeats , @xmath9 , resulting in different magnetization loops as evidenced by the moke @xmath49 . in all cases * a - d * the fringe - field response correlates exactly with the field - range where the magnetic film is unsaturated , and therefore emits fringe fields into the organic device . ]layer between them .this control experiment is important for establishing the correct interpretation of the data ( see text ) , but results in a greater distance between magnetic film and organic device , leading to a smaller coupling between the two and a smaller fringe - field effect . ] |

despite the high prevalence and poor outcome of patients with metastatic lung cancer , the mechanisms of tumour progression and metastasis remain largely uncharacterized .
we modelled human lung adenocarcinoma , which frequently harbours activating point mutations in kras1 and inactivation of the p53-pathway2 , using conditional alleles in mice35 .
lentiviral - mediated somatic activation of oncogenic kras and deletion of p53 in the lung epithelial cells of kraslsl - g12d/+;p53flox / flox mice initiates lung adenocarcinoma development4 . although tumours are initiated synchronously by defined genetic alterations , only a subset become malignant , suggesting that disease progression requires additional alterations .
identification of the lentiviral integration sites allowed us to distinguish metastatic from non - metastatic tumours and determine the gene expression alterations that distinguish these tumour types .
cross - species analysis identified the nk-2 related homeobox transcription factor nkx2 - 1 ( ttf-1/titf1 ) as a candidate suppressor of malignant progression . in this mouse model ,
nkx2 - 1-negativity is pathognomonic of high - grade poorly differentiated tumours .
gain - and loss - of - function experiments in cells derived from metastatic and non - metastatic tumours demonstrated that nkx2 - 1 controls tumour differentiation and limits metastatic potential in vivo .

– Democrats nearly had another political disaster on their hands thanks to Evan Bayh, writes David Kurtz. They got lucky, however, when a no-name cafe owner failed to come up with enough signatures by today's deadline to represent Democrats in the primary. Now that Tamyra d'Ippolito is out of the picture—even though she claimed to have the signatures earlier in the day—party officials in Indiana will be able to place a more seasoned candidate on the ballot. The development "would seem to end the d'Ippolito boomlet—fueled partly by conservatives looking to cause trouble for Democrats—before it even began, but we're still confirming the particulars," writes Kurtz at Talking Points Memo. The would-be candidate raised eyebrows when she accused the party "machine" of getting her bumped from Rachel Maddow's show. An NBC official responds to Ben Smith at Politico: "I think you can guess that Rachel doesn't really have a tight connection with the 'machine' politics of the Indiana Democratic Party." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Our Eric Kleefeld has spent the morning trying to make heads or tails of what’s going down in Indiana. Thing are still a bit hazy, but it looks like Democrats have avoided ending up with a political unknown as their nominee to succeed Evan Bayh in the U.S. Senate. Today is the deadline for prospective candidates for the Democratic primary to file with each county clerk the petitions required by law in order to appear on the ballot. Earlier this morning Tamyra d’Ippolito — calling her a longshot is probably too generous — told us she already had all the signatures she needed to qualify. But shortly thereafter she told Greg Sargent that she didn’t really have them but she would have them by the noon deadline. Around that time, the state Democratic Party chairman, Dan Parker — a close Bayh ally, it should be noted — told us d’Ippolito wasn’t even close to having enough signatures to qualify. By his count, she had 22 signatures filed statewide, out of the 4,500 the law requires. Just now, after the noon filing deadline passed, Eric checked in with the clerk in Marion County — the largest county in the state, where Indianapolis is located, which contains an entire congressional district. Indiana’s qualifying law, like many state’s, is byzantine. One requirement is that you have to have at least 500 signatures from each congressional district. The clerk tells us that d’Ippolito has filed a total of two signatures from residents of the congressional district wholly within Marion County. That would seem to end the d’Ippolito boomlet — fueled partly by conservatives looking to cause trouble for Democrats — before it even began, but we’re still confirming the particulars. But we’re not out of the woods yet when it comes to obscure election rules because now the selection of a Democratic nominee is in the hands of state party officials. ||||| And the Bloomington Democrat's 15 minutes appear to have ended. She turned in just three of the 500 signatures required in one of nine congressional districts, which disqualifies her, demonstrating the limits of last-minute, disorganized blog and Twitter posts in getting people to participate in tactical political mischief. (Reminds me a bit of the so-called Limbaugh effect actually — there's little evidence people actually act like this.) Also, an NBC official e-mails to contest the candidate's theory that she was bumped from Rachel Maddow's show last night for nefarious reasons, saying that instead NBC chose to do a broader segment on Bayh's retirement. "I think you can guess that Rachel doesn't really have a tight connection with the 'machine' politics of the Indiana Democratic Party," the official said. |

– Right up there with snakes on planes are scorpions, and the presence of one on an Alaska Airlines flight yesterday caused a bit of a stir: As the Oregonian reports, Flight 567 was taxiing on the runway at LAX when a scorpion—apparently having hitched a ride from Mexico in the bag of a returning tourist—stung a female passenger, causing the plane to return to the gate so the woman could be checked by medics. She refused additional medical treatment, notes the AP, and the flight later continued to Portland. Oregon State University's men's basketball team was aboard. As for the scorpion, an uphappy ending: Flight attendants killed it.

He says the plane returned to the gate and the woman was checked by medics. She refused additional medical treatment but didn't get back on the plane. Meanwhile, flight attendants killed the scorpion and checked overhead compartments for any additional unwanted arachnids. The flight then took off at 8:40 p.m., about an hour late. Members of Oregon State University's men's basketball team were on the flight, Cosgrove said. He says it's unclear how the scorpion got on the plane, but the flight originated in Los Cabos, Mexico. ||||| A plane carrying the Oregon State men's basketball team -- and, coincidentally, Oregonian/OregonLive reporter Tyson Alger -- from Los Angeles to Portland on Saturday had to return to the gate at LAX when a woman was stung by a scorpion. Passengers were told the scorpion hitched a ride in the carry-on bag of a passenger who had been to Mexico. The Alaska Airlines flight landed at PDX about 11 p.m. after a 30-minute delay in Los Angeles. The University of Portland women's basketball team was on board as well.

– Lindsey Graham doesn't seem to have a problem with Bruce Jenner's transition to Caitlyn: "If Caitlyn Jenner wants to be safe and have a prosperous economy, vote for me," the presidential candidate tells CNN today, per the Hill. "I’m into addition. I haven’t walked into her shoes. I don’t have all the answers to the mysteries of life. I can only imagine the torment that Bruce Jenner went through. I hope she has found peace." He continues: "I’m a pro-life, traditional marriage kind of guy. But I’m running to be president of the United States. If Caitlyn Jenner wants to be a Republican, she is welcome in my party." Jenner, notes the Hill, had previously identified as a Republican. Scott Walker seemed equally eager to avoid a rush to judgment, telling ABC that "I think it’s a personal decision. And to me, I don’t know that there’s anything more to comment on. It’s a personal decision." He did take aim at same-sex marriage, notes the Hill: "If the court decides (to rule in favor of gay marriage), the only next approach is for those who are supporters of marriage being defined as between one man and one woman is ultimately to consider pursuing a constitutional amendment." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | House Homeland Security Chairman Michael McCaul (R-Texas) said on Sunday that evidence points toward Chinese involvement in a federal data breach earlier this year. ADVERTISEMENT “I believe, in my judgment, that all threat indicators point to China,” McCaul told host John Dickerson on CBS’s “Face the Nation.” “In my judgment, China was responsible for this.” “This is the most significant data breach in U.S. history,” he added. The White House revealed on Thursday that hackers had exposed the private data of 4 million current and former federal employees last April. McCaul said on Sunday that the cyberattack’s target, the Office of Personnel Management (OPM), likely indicated that hackers had intelligence gains in mind. “It was perhaps nation-state sponsored because of the way it was done,” he said. “It was done for espionage.” “This is an area where there are no rules to the game,” McCaul added. “It raises all sorts of issues for Americans.” McCaul said that the Islamic State in Iraq and Syria (ISIS) has also started using the Internet to damage American interests. The extremist group, he said, had made major gains by using social media to inspire attacks both here and abroad. “You talk about the new wave of terrorism, this is pretty much it,” McCaul said. “This is a hard thing to stop.” McCaul additionally said that the Transportation Security Administration (TSA) further complicated the issue of national security. The TSA announced last Monday that screeners had failed an internal test to find fake explosives and weapons at most of America’s busiest airports. “It was an abysmal performance,” McCaul said on Sunday. “In the high threat environment that we’re in right now, this is totally unacceptable.” ||||| Wisconsin Gov. Scott Walker (R) says if an upcoming ruling by the Supreme Court results in the legalization of same-sex marriage, opponents should consider pursuing a constitutional amendment banning it. “If the court decides that, the only next approach is for those who are supporters of marriage being defined as between one man and one woman is ultimately to consider pursuing a constitutional amendment,” he said in an interview airing Sunday on ABC News’s “This Week.” ADVERTISEMENT Walker, who said he believes marriage is between one man and one woman, added that the decision should be “left up to the states.” The Wisconsin governor said during the interview he plans to announce his 2016 intentions “shortly” after the end of June. The high court is expected to issue its decision on same-sex marriage before its current term ends at the end of the month. |

– Ever cringe when adding another bag of garbage to the world's waste? Then consider Justin Vrany, who says his Chicago restaurant has produced only 8 gallons of garbage in two years—the amount many restaurants toss in a single hour, Time reports. In fact, an artist picked up those 8 gallons for a sculpture, "so we are now official a zero-waste restaurant," he says in a new video. What's more, his establishment runs on renewable energy and gets produce and meat from local farms. Yet Vrany admits he wasn't always so green-conscious. "I used to eat whatever and do whatever I wanted to do," he says. But he went back to school and learned "how to utilize" waste. "It just opened my mind." His inspiration for running Sandwich Me In also stems from his parents, who were once jobless and had to make a single turkey stretch over 3 or 4 days: "That kind of stuff sticks with you." Now he makes 98% of food in-house, including drinks, and sends fruit and vegetable compost to a Wisconsin farm to feed chickens that lay his restaurant's eggs, CBS Chicago reports. Still, he doesn't "want to be in the spotlight," he says. "I just want to change things, for my kids, for all of us." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Jason Vrany wants to save the planet, one sandwich at a time. His Chicago restaurant, Sandwich Me In, prides itself on making great food at an affordable price and on the fact that they make almost no garbage. By focusing on recycling, composting and rethinking the way the typical fast-casual restaurant is run, Sandwich Me In has only produced eight gallons of trash in over two years of business. Many restaurants produce that much waste in a single hour.

Make Environmental Degrees Free ||||| February 25, 2014 3:15 PM Sandwich Me In sandwiches. (Credit: Sandwich Me In) By John Dodge CHICAGO (CBS) — In one year, Justin Vrany produced only eight gallons of garbage. That figure would be mighty impressive for one man, but it is downright mind-blowing when you consider this: That’s the total amount of garbage generated by his Lake View restaurant, Sandwich Me In. Eight gallons. One year. And a lot of that was garbage brought in by customers. Vrany has taken the concept of sustainability very seriously. When he built his restaurant, 3037 North Clark St., in 2012, he said he only filled up one-quarter of a dumpster with debris. All of the furniture and equipment in the restaurant is either used or refurbished. All of the restaurants waste is composted or recycled. For example, the vegetable and fruit compost are sent to Byrant Family Farms in Wisconsin to feed the chickens that lay the eggs for the restaurant. The restaurant’s power is wind-generated, Vrany says. The used oil is recycled in bio-diesel engines. A total of 98 percent of the food is made in-house, even the drinks. Ingredients come from local farms. Vrany estimates that his restaurant’s carbon footprint is 85 less than of what a typical quick service restaurant would use in one day. “We want to show people that there is food out there that has taste, that can be sourced locally and can reduce the impact on the environment,” Vrany said in a video posted on the restaurant’s website. |

– Scientists checking a camera set up to observe otters in northern Italy were thrilled when another furry creature wandered into the frame—the first beaver seen in the country in centuries. The last recorded sighting of a beaver in Italy—where they were hunted for food in the Middle Ages as a "white meat" that Catholics could eat on Fridays—was in 1471, the CBC reports. The male beaver has been nicknamed "Ponta" in honor of photographer Renato Pontarini and the bridges they are famous for building, Il Globo reports. Researchers, who suspected a new kind of animal was in the area after being alerted to unusual tracks, believe Ponta is the descendant of a group of beavers reintroduced to the Danube region around 30 years ago. (Argentina, meanwhile, says it has far too many beavers.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The European beaver has been spotted in Italy for the first time in almost 500 years. The male beaver has been spotted several times in the last week. (Photo: ANSA/Renato Pontarini) The male beaver has been spotted several times in the last week. (Photo: ANSA/Renato Pontarini) Camera traps captured images of a male beaver in the forests of Tarvisiano, in the north-eastern region of Friuli-Venezia Giulia which shares a border with both Austria and Slovenia. The beaver, who seems to be a lone ranger, has been caught on camera several times over the past week. Wildlife experts suspect he crossed the border to Italy from Austria. Locals believed the area had a visitor when they noticed unusual tracks on the ground and marks on branches, so they contacted conservation experts from the University of Turin, who then set up hidden cameras in the area. Researchers have nicknamed the historic creature “Ponta” in honour of Renato Pontarini, the photographer who first caught him on camera. The cute critter’s new name also refers to the bridges that beavers are famous for creating, as the word ponte is the Italian for “bridge”. European beavers were once common from Britain to China, but were hunted to near extinction for their fur and castoreum, an anal secretion the animals use to mark their territories, which – believe it or not – was once used to add scent to perfume and flavour to food. While the species has been successfully reintroduced in parts of its former habitat, including in Croatia, it remained extinct in Italy from the 16th century until now. ||||| An animal considered a Canadian icon has resurfaced in Italy after an absence of more than 500 years. A beaver was captured on camera in northeast Italy, marking the first sighting of the animal in that country since 1471. Scientists were observing otters last week when the male beaver was seen walking into frame. While the beaver was valued in Canada for its pelt, the animal was widely hunted and eaten in Italy and other parts of Europe during the Middle Ages and considered white meat — the same as fish — so Catholics could eat them on Fridays. The animal didn't make a return to Central Europe until the 1980s, when conservationists reintroduced the species with beavers from northern Russia. Scientists believe the beaver caught on camera is likely a descendant of a group that was introduced by conservationists to the Danube river, which runs through a large swath of Eastern and Central Europe. The European beavers are a distinct species, different from Canadian beavers. |

– We're one step closer to finding Chuck Hagel's replacement: President Obama announced today he's nominating Pentagon ace Ashton Carter to take over as secretary of defense, the AP reports. Although some fear that Carter's insider status may hamper his ability to come up with creative solutions to challenging issues, others say his extensive expertise on a variety of subjects—including nuclear weaponry and the navigation of global hot spots—will make the transition seamless, the Wall Street Journal notes. "On day one, he'll be ready to hit the ground running," Obama said in his announcement this morning. For a scientist who's never served with the armed forces, Carter has had a storied defense career: He started out as Bill Clinton's assistant defense secretary in 1993, became undersecretary of defense in 2009, and served as deputy defense secretary from 2011 to 2013. Carter's experience will prove key, as he'd be entering a role faced with growing world threats—for example, Islamic militants in the Middle East and confrontations with Russia—all of which he'd have to face with a declining defense budget, the Journal notes. He's stood out in helping to create state-of-the-art war equipment, such as mine-resistant vehicles used in Iraq and Afghanistan, the New York Times notes. "It's no exaggeration to say there are countless Americans who are alive today, in part because of Ash's efforts," Obama said during his announcement. From his autobiography, Carter appears capable of withstanding the often-brutal political environment. "Public service at senior levels in Washington is a little bit like being a Christian in the Coliseum," he wrote in 2007, as per the Journal. "You never know when they are going to release the lions and have you torn apart for the amusement of onlookers." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Defense Secretary Chuck Hagel gained a reputation in some circles for sticking closely to talking points provided by his staff, creating the impression among various Pentagon officials that he had a thin grasp of military issues. Ashton Carter, whom President Barack Obama nominated Friday as Mr. Hagel’s successor, is seen by many of his supporters as the polar opposite. Mr.... ||||| Mr. Carter is a Democrat but not one of the core Obama loyalists, a group that includes Ms. Rice and Denis R. McDonough, the White House chief of staff. Like Mr. Gates, Mr. Carter is widely viewed as being to the right of the president on issues like American policy in Syria and the pace of releasing prisoners from the military prison at Guantánamo Bay. Both are issues in which he could come into conflict with Ms. Rice. Mr. Carter is methodical and sharp, but not necessarily patient. Mr. Obama’s apparent willingness to wait years for the Syrian civil war to play out may frustrate Mr. Carter, who former colleagues say often pushed for clarity in policy goals — and then moved swiftly to pursue those goals. “I would not call him a hawk,” said William J. Perry, a defense secretary under President Bill Clinton and one of Mr. Carter’s mentors. “But he is pretty hard-nosed about what can be done with American power, and he is willing to use it when appropriate.” Vikram J. Singh, who worked under Mr. Carter when the latter was deputy defense secretary, agreed with that assessment. “Ash Carter will probably be very cleareyed about looking at the risk of a set of options, and accepting a certain amount of risk, and moving forward to implement as efficiently and quickly as possible.” If Mr. Carter ends up to the right of Mr. Obama on Syria and the fight against the Islamic State, it will not be the first time. Former aides and administration officials say that Mr. Carter — like Mr. Hagel and Secretary of State John Kerry — was shocked last year when Mr. Obama, after a walk and talk on the South Lawn of the White House with Mr. McDonough, decided at the last moment to call off military strikes against the Syrian president, Bashar al-Assad, who had charged across Mr. Obama’s own “red line” on the use of chemical weapons. Now, Mr. Carter will inherit a military strategy that has made some progress in reversing the gains of the Islamic State in Iraq, but has made dealing with Mr. Assad a less important issue. Despite public shows of solidarity, the United States and its partners cannot agree whether their primary enemy in Syria is the Sunni militant group or Mr. Assad. |

– Who better to recommend a good travel book than the author of Holidays in Hell, a self-described guide to the "world's worst places"? Now that PJ O'Rourke's follow-up, Holidays in Heck, is on shelves, O'Rourke reveals his six favorite travel books in the Daily Beast: Domestic Manners of the Americans, Fanny Trollope: After living "two miserable years" in Cincinnati, Anthony Trollope's mother wrote "the great anti–de Tocqueville account of America." With complaints of pigs running the streets and general filthiness, "she sounds like my mother on the subject of foreign travel." Fear and Loathing in Las Vegas, Hunter S. Thompson: "Actually, nothing happens on this journey," writes O'Rourke. The subjects just get wasted, scare some people, and behave poorly. "From this Thompson created a work of enduring genius." Steaming to Bamboola, Christopher Buckley: Although it's a comic novel, O'Rourke calls Buckley's writing "awfully realistic," saying Bamboola "is what Two Years Before the Mast would have been like if Richard Henry Dana Jr. had had a sense of humor."

His book is naive enough to qualify as the original Lonely Planet guide. Here is Marco’s bug-eyed take on paper currency: “The Great Khan has money made for him out of the bark of trees … Of this money the Khan has such a quantity made that with it he could buy all the treasure in the world.” Domestic Manners of the Americans Fanny Trollope In the 1820s Anthony Trollope’s mother spent two miserable years in Cincinnati and wrote the great anti–de Tocqueville account of America. Pigs ran wild in the streets. “And though it is not very agreeable to live surrounded by herds of these unsavory animals, it is well they are so numerous, and so active in their capacity of scavengers, for without them the streets would soon be chocked up with all sorts of substances in every stage of decomposition.” She sounds like my mother on the subject of foreign travel. Personal Narrative of a Pilgrimage to Al-Madinah & Meccah Sir Richard Francis Burton Burton, the most rash and irrepressible adventure seeker of the 19th century, disguised himself as an Afghan and became the first European to fully explore the forbidden holy cities of Islam. He penetrated the Kaabah itself, secretly sketching its interior on his shawl while pretending to pray. But his book’s a slog. He was a terrible writer. You’re better off reading Burton, the excellent biography by Byron Farwell. Fear and Loathing in Las Vegas Hunter S. Thompson Actually, nothing happens on this journey. Two men in early middle age visit Las Vegas while intoxicated. They frighten a few people (mostly each other), are rude to bystanders and astonish a cleaning lady. A couple of rental cars and several bathrooms are left the worse for wear. Then they skip out on their hotel bill. From this Thompson created a work of enduring genius. Another Day of Life Ryszard Kapuscinski Despite working for communist Poland’s aptly named PAP press agency, Kapuscinski was the 20th century’s best foreign correspondent. In 1975 he went from benighted Warsaw to far more benighted Luanda to cover the civil war in Angola. He evokes the sweating, choking fear that’s ever-present in guerrilla combat more effectively than anything short of my coming over to your house and shooting at you. |

– Three boys have found a part of a mastodon jawbone while exploring family property in Mississippi. The Vicksburg Post reports that two brothers and a cousin made the discovery on plowed land near Bovina, a small community east of the Mississippi River. The three were on spring break from school when they found something they initially thought was a log, then saw that it had teeth. Lynett Welch, mother of the two brothers, says her husband took the item to the Mississippi Museum of Natural Science in Jackson, where paleontology curator George Phillips confirmed it was a lower left jawbone from a mastodon. Phillips says finding half of a mastodon's lower jaw is "very extraordinary," the AP reports. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | When most students go on spring break, they go to the beach or take a vacation with the family. Shawn and Caid Sellers and their cousin Michael Mahalitc became dinosaur hunters — in a sense. While walking through a plowed area on their family’s property in Bovina, the boys uncovered a relic from earth’s ancient history; the lower left jawbone of a mastodon. “I just saw it in the dirt,” Caid said. “I thought it was a log, then I turned it over and saw the teeth. It was heavy. I tried to lift it. We all (he, Shawn and Michael) tried to lift it.” “The boys came in and said they found a dinosaur bone,” said Lynett Welch, Shawn and Caid’s mother. “I called the (Mississippi) Museum of Natural Science and told them what the boys found. My husband took it over to the museum the next day and they confirmed it was a mastodon bone. “The man we talked to told us how to preserve it.” Mastodons roamed the earth about 2.6 million to 11,700 years ago, and their remains have been found all over the world. Welch said the family has been finding petrified wood and other items on their property for years. But finding the mastodon bone was a bit of surprise. “We’re talking about a very mature individual,” George Phillips, paleontology curator at the museum, said of the boys’ find. He said the estimated age of the jaw’s owner was determined by the number of teeth in the jaw. Mastodons, he said had 24 teeth over their lifetime, “But there’s no more than two or three teeth in use at any time.” The teeth form and erupt, or grow, in the back of the mouth and move forward in the mouth until they are shed at the tip of the jaw. “They actually cleave off over time; the tooth is gradually eroding and breaking apart and shed out the front.” The two teeth in the jaw the boys found, are the last two teeth in the left jaw; the animal would have had a total of eight teeth in its mouth. Phillips said the jaw was the third mastodon find he’s examined in the past month, adding he has seen a photo of a molar and tusk, both found in the Mississippi River, and the boys’ find. Finding half of a lower jaw, he said, “Is very extraordinary.” Caid said he plans to preserve the jawbone and keep it, and his mother said she doesn’t doubt more finds could be coming. “There’ll never be another spring break like this one,” Caid added. |

– Conservationists say they have confirmed the existence of lions in a remote national park in Ethiopia, a rare piece of good news for a threatened species whose numbers have plunged in many parts of Africa, the AP reports. Born Free, a charity based in Britain, said in a statement Monday that the discovery was made in Alatish National Park in northwest Ethiopia, on the border with Sudan. The charity says conservationists obtained camera trap images of lions and also identified lion tracks, confirming reports from local residents that lions were in the area. "During my professional career I have had to revise the lion distribution map many times," lead researcher Hans Bauer tells New Scientist. "I have deleted one population after the other. This is the first and probably the last time that I’m putting a new one up there." Alatish borders on Sudan's Dinder National Park, which Bauer thinks is also home to lions—with a combined population of 100 to 200. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Wildlife Conservation Research Unit (WildCRU) In the savannah of Alatash National Park, the lion sleeps tonight. This remote part of north-west Ethiopia was considered a possible habitat for lions, but it is seldom visited by people. Now an expedition by the University of Oxford’s Conservation Research Unit has discovered that lions are indeed alive and well in the park – a rare extension of their known range. Advertisement “During my professional career I have had to revise the lion distribution map many times,” says Hans Bauer, who led the expedition. “I have deleted one population after the other. This is the first and probably the last time that I’m putting a new one up there.” To spot the lions, Bauer and his team set up camera traps on a dry river bed. “While I was walking to find some trees to put the camera on, I already saw some footprints,” says Bauer. “That was the eureka moment when I was sure that there really are lions.” Caught on camera Then it was a case of catching them on film, and on the second night, the lions obliged. Alatash is adjacent to a much larger national park in Sudan, Dinder National Park. Bauer believes it’s likely there are lions there as well, with perhaps 100 to 200 individuals in the two parks combined. About 20,000 lions are left in the wild across Africa. Lion populations in west and central Africa are declining, and may halve in 20 years. Bauer thinks the lions of Alatash face fewer threats than many populations. “The situation is fairly positive,” he says. “I think the fact that the Ethiopian government recently made it a national park is a giant leap forward. Now we have to support them in improving park management, but I think they’re taking it very seriously.” Read more: Last of the lions ||||| JOHANNESBURG (AP) — Conservationists say they have confirmed the existence of lions in a remote national park in Ethiopia, a rare piece of good news for a threatened species whose numbers have plunged in many parts of Africa.

– Truly horrific: A Florida prison inmate murdered his cellmate Thursday by strangling him, pulling out his eyes, and strolling into the prison chow hall wearing the guy's ear around his neck—a killing that highlights bigger problems at Columbia Correctional Institution, the Miami Herald reports. Officials have identified the victim as Larry Mark, a 58-year-old serving life for murder, but the killer's name hasn't been released while the Florida Department of Law Enforcement investigates. Two prison sources tell the Herald that Mark angered his cellmate by pestering him; after the killing, the cellmate dropped Mark's eyes in a cup and told fellow prisoners he was planning to drink or eat them later on. The dorm where Mark died was manned by just one control-room officer and a sergeant who was busy elsewhere in the compound—just one example of staff shortages that have left the facility rattled. The problem worsened hours later when a gang knife-fight erupted over smuggled contraband elsewhere in the prison and left four hospitalized, per the Gainesville Sun. According to an officer at the Lake City facility, staff shortages contribute to contraband deliveries (sometimes by drone) and the proliferation of K2, a powerful synthetic marijuana often used by prisoners. And Columbia Correctional isn't alone: Gangs control many of Florida's 50 prisons, says a former prison inspector, while records show that inmate deaths in the state's system are more frequent than ever. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | A Columbia Correctional Institution Annex inmate killed his cellmate early Thursday morning — hours before an altercation at an adjacent prison sent four inmates to hospitals, reported the Florida Department of Corrections. Larry Mark, 58, died in the facility 47 miles north of Gainesville at about 6:15 a.m. The name of the inmate who killed him was not released and the death is under investigation by the Florida Department of Law Enforcement. DOC said the incident was separate from an altercation involving 10 inmates at the adjacent Columbia Correctional Institution in Lake City that occurred Thursday afternoon. “Any loss of life at the hands of an inmate is intolerable, and we are working with our partners at FDLE to investigate this death and ensure anyone responsible is held accountable to the fullest extent of the law,” DOC Secretary Julie Jones said in the statement. FDLE spokeswoman Gretl Plessinger said the agency is investigating the attack but would not release additional information. “It’s an active case,” Plessinger said. “No charges have been filed and no arrests have been made so we haven’t released a name.” The DOC website indicates Mark was serving a life sentenced for first-degree murder or attempted murder on a 1982 Broward County conviction. DOC said the murder of Mark was separate from an afternoon melee at Columbia Correction that hospitalized four. Communications between ambulances and UF Health Shands Hospital indicate that at least some of the injured were taken to Shands. DOC said no staff members were injured. The agency did not give any information about the cause of the altercation, where in the prison it occurred or how long it lasted. It is the second state prison incident in the region in a week. On Sept. 7, 100 inmates were involved in a disturbance in the recreation yard at Hamilton Correctional Institution Annex in Jasper, the Florida Times-Union reported. DOC spokeswoman Michelle Glady said the Hamilton event was “not a riot” and resulted in no serious injuries. ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

– Writer, inaugural poet, storyteller, mentor, civil rights activist, Grammy winner, journalist, streetcar conductor, and even madam—Maya Angelou wore a vast rainbow of hats during her 86 years, and Americans wasted no time today in paying homage to the fiercely eloquent force of nature. Without ado: President Obama: Citing "a brilliant writer, a fierce friend, and a truly phenomenal woman," Obama noted that his own sister is named for the poet, who "above all, was a storyteller—and her greatest stories were true. The voice she found helped generations of Americans find their rainbow amidst the clouds, and inspired the rest of us to be our best selves." President Clinton: "America has lost a national treasure; and Hillary and I, a beloved friend. I will always be grateful. The poems and stories she wrote and read to us in her commanding voice were gifts of wisdom and wit, courage and grace." Oprah Winfrey: "I've been blessed to have Maya Angelou as my mentor, mother/sister, and friend since my twenties. She was there for me always, guiding me through some of the most important years of my life. The world knows her as a poet but at the heart of her, she was a teacher. 'When you learn, teach. When you get, give,' is one of my best lessons from her. She moved through the world with unshakeable calm, confidence and a fierce grace. I loved her and I know she loved me. I will profoundly miss her. She will always be the rainbow in my clouds." Over at Slate, Dee Lockett reminds us that "Angelou’s talents extended well beyond the written and spoken word." In the '50s, Angelou was an aspiring singer and dancer who eventually recorded an album, Miss Calypso, which in turn inspired her first film, Calypso Heat Wave. At Salon, Laura Miller lauds Angelou as "the voice of America," a poet who even had a line of Hallmark cards for which she was mocked, "but the public adored her and found in her words both wisdom and comfort. Angelou’s is a style that lends itself well to the realm of social media, with its informal habit of sharing and passing along quotations and mottos." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Still from YouTube “Music was my refuge. I could crawl into the space between the notes and curl my back to loneliness,” the revered poet and activist, Maya Angelou, who died Wednesday at age 86, once described her relationship with songwriting. As the former U.S. Poet Laureate and the author of a classic memoir, she’ll likely be remembered most for her writing, but Angelou’s talents extended well beyond the written and spoken word. In fact, in the early 1950s—a decade before her first published writing—Angelou started out as an aspiring dancer and singer who slowly gained a following from her performances in local San Francisco nightclubs. And in 1957, at the height of the calypso movement—a style popularized by Harry Belafonte—Angelou recorded her first and only album, Miss Calypso. In it, she covers Nat King Cole’s “Calypso Blues” and Louis Jordan’s “Run Joe,” using her deep vibrato to create a simmering fusion of jazz and Afro-Caribbean rhythms. The album even partly inspired her first feature film, Calypso Heat Wave, in which she both starred and sang. Though short-lived, Angelou’s music career also included songwriting credits for the legendary B.B. King on two tracks he recorded for the Quincy Jones-produced soundtrack to Sidney Poitier’s For Love of Ivy. Advertisement As we reflect on Angelou’s life and her words, it’s worth taking a few minutes at least to get acquainted with the music she left us with as well. “Run Joe” (1957, Calypso Heat Wave) “Stone Cold Dead in the Market” (1957, Miss Calypso) Advertisement “You Put It on Me” (recorded by B. B. King, written by Angelou, 1968, For Love of Ivy soundtrack) “The B.B. Jones” (recorded by B. B. King, written by Angelou, 1968, For Love of Ivy soundtrack) “Sesame Street: My Name” ||||| But Angelou always felt teaching to be her true vocation, and often framed her other activities in that light. She was the Reynolds professor of American studies at Wake Forest University in Winston-Salem. Perhaps she became best known to the American public through her work as a poet (as improbable as that may seem given the obscurity poets generally endure in this country). There have been 19 poets laureate since the position was created in 1986 and Angelou never held the title herself, but if anyone qualified for the position, it was she. Her reading of her poem "On the Pulse of the Morning" at the inauguration of President Bill Clinton captured the potential and optimism many Americans felt at the passing of the Reagan-Bush era. She was presented with the nation's highest civilian honor, the Presidential Medal of Freedom, by President Barack Obama in 2011. |

– Donald Trump is going to have to get through the final weeks of his campaign without Jim Murphy, his national political director, who has decided to take a "step back" for undisclosed reasons. "I have not resigned but for personal reasons have had to take a step back from the campaign," Murphy, a longtime GOP political operative, tells Politico. Trump aides say Murphy has been absent from the campaign over the last few days. The Hill reports that Murphy, who joined the campaign in June and set up field operations in battleground states, was a close ally of former Trump campaign chief Paul Manafort.

Jim Murphy, Donald Trump’s national political director, is no longer playing an active role on the campaign, according to three sources briefed on the move – a troubling development for the Republican nominee coming just 19 days before the election. "I have not resigned but for personal reasons have had to take a step back from the campaign," Murphy said in a statement to POLITICO. He did not elaborate on the reasons for his departure. Story Continued Below Several Trump aides said that Murphy has been conspicuously absent in recent days as the campaign mobilizes for the final push. Since joining the Trump campaign in June, Murphy, a longtime party operative, has played a key role in setting up field programs in battleground states. He has emerged as a central point person between top Trump campaign officials and the Republican National Committee. Murphy also helped to oversee floor operations at the Republican National Convention in July. The move comes at an inopportune time for the campaign, with little more than two weeks remaining until Election Day and Trump cratering in opinion polls. There are widespread concerns in Republican circles that Trump’s swing state infrastructure lags far behind Hillary Clinton’s – something that could have implications for the party up and down the ballot. Murphy is a close ally of Paul Manafort, Trump’s former campaign chairman, having worked together on Bob Dole’s 1996 presidential campaign. Manafort resigned from the Trump campaign in August. It’s the latest departure in a campaign rife with turnover. Manafort resigned from the campaign in August, just two months after succeeding Trump’s first campaign manager, Corey Lewandowski, who was fired. Other campaign hands, including longtime party strategist Ed Brookover, have also left. |

we have measured magnetization @xmath0 , electrical resistivity @xmath1 , thermal conductivity @xmath2 , and thermopower @xmath3 of polycrystalline samples of nd@xmath4eu@xmath5nio@xmath6 ( @xmath7 ) as a function of temperature and external magnetic field .
the data indicate a metal - insulator ( mi ) transition in a wide range of temperature ( @xmath8 k ) . the magnetic susceptibility @xmath9 data , after the subtraction of the rare - earth contribution , exhibit a curie - weiss like behavior at temperatures above @xmath10 .
although a clear antiferromagnetic af transition of the ni sublattice is observed at @xmath11 , @xmath9 still increases down to 5 k , suggesting a heterogeneous ground state .
the thermal conductivity of the ndnio@xmath6 compound is not affected by an external magnetic field of 90 koe in a wide range of temperature , and its temperature dependence below 15 k is approximately quadratic , strongly suggesting the presence of disorder . the data also show that @xmath12 is negative above @xmath10 and varies linearly with temperature , as expected in a typical metal with negative charge carriers .
below @xmath10 , @xmath12 does not follow the expected behavior of insulating compounds .
there is a minimum close to 120 k , and @xmath12 changes its sign at @xmath13 k , indicating a competition between two types of charge carriers . a pronounced peak in @xmath12 at @xmath14 k does not follow the expected phonon - drag temperature dependence either above or below @xmath15 and the peak remains unaltered under magnetic fields up to 90 koe . however , its magnitude is enhanced by @xmath16% with applied magnetic field , exhibiting a clear magnetothermopower effect .
the combined results indicate a coexistence of ordered and disordered phases below @xmath17 and that an applied magnetic field is suitable for enhancing the thermoelectric properties of these perovskites close to @xmath15 .
transition metal oxides _ _ r__nio@xmath18 ( _ r _ = rare earth , _ r _ @xmath19 la ) are interesting due to their transport and magnetic properties caused by strong electronic correlation effects .
these perovskites show a marked metal - insulator ( mi ) transition at a temperature @xmath10 which increases when the ionic radius of the rare earth decreases , ranging from @xmath20 k for _ r _ = nd to @xmath21 500 k for _ r _ = eu .
they also show an antiferromagnetic ( af ) phase transition at a temperature @xmath17 related to the ordering of the ni sublattice . for _ r _ = nd , @xmath22k , and for _ r _ = eu , @xmath23 k , well below @xmath10 [ 1 ] .
neutron powder diffraction ( npd ) experiments performed in _ r _ = nd showed an unexpected propagation vector @xmath24 = ( 1/2 , 0 , 1/2 ) , probably related to an inhomogeneous ground state composed of alternating ferromagnetic and af couplings between nearest - neighbor ni@xmath25 along the three pseudocubic axes .
this unusual af ordering has been attributed to the presence of an orbital ordering ( oo ) that would break down the inversion center at the ni site in the orthorhombic symmetry [ 2 ] .
other npd peaks were reported below @xmath26 k and associated with a magnetic ordering of the ni@xmath25 spins [ 3 ] .
results in smaller rare earth ions ( _ r _ = ho , y , er , and lu ) also suggested a change in the crystal symmetry , from orthorhombic @xmath27 to monoclinic @xmath28 , across the @xmath10 transition , resulting in a charge disproportionation of ni@xmath25 cations [ 4 ] . electron diffraction and raman scattering experiments indicated a symmetry break also for _ r _ = nd [ 5 ] , and a direct observation of charge ordering ( co ) in epitaxial ndnio@xmath18 films , using resonant x - ray scattering , has also been reported [ 6 ] .
these results led to the proposition that charge disproportionation , and a consequent change in the crystal symmetry , may occur below @xmath10 for all the members of the _ _
r__nio@xmath18 family , making the picture of oo obsolete [ 6 ] .
recent soft x - ray resonant scattering experiments indicated that oo is absent at the mi transition , that the complex af ordering previously proposed may not be correct , and that the magnetic structure is likely to be non - collinear [ 7 ] . although some properties of these systems are well established , there are still many doubts regarding their low temperature ground state that seems to be inhomogeneous , dominated by the coexistence of at least two different phases
. the data regarding the thermal properties as well as thermopower of these systems could be of interest to better understand their properties at low temperatures .
the lack of systematic measurements of these properties is the main motivation for the development of this work .
polycrystalline samples of nd@xmath4eu@xmath5nio@xmath18 ( @xmath7 ) were prepared by using sol - gel precursors , sintered at high temperatures ( @xmath211000 @xmath29c ) , and under oxygen pressures up to 80 bar [ 8 ] .
the samples were characterized by means of x - ray diffraction ( xrd ) measurements in a brucker d8 advanced diffractometer using cu @xmath30 radiation ( @xmath31 ) .
all samples were found to be single phase materials to xrd analysis [ 9 ] .
magnetization @xmath32 measurements were taken in a commercial superconducting quantum interference device ( squid ) magnetometer .
the runs were performed cooling down and warming up the samples , with temperature ranging from @xmath33 to @xmath34 k and under dc magnetic fields as high as 10 koe .
electrical resistivity @xmath35 measurements were performed by using the dc four - probe technique .
thermopower @xmath12 and thermal conductivity @xmath36 were measured by using a physical propertie measurement system ( ppms ) equipment from quantum design .
measurements of @xmath12 and @xmath36 were also performed for the pristine compound ( _ r _ = nd ) in an applied magnetic field of 90 koe .
the temperature @xmath10 was defined through the sharp peak observed in the curves of @xmath37 vs @xmath38 in the warming up cycle . for temperatures below @xmath39
k , @xmath37 changes and increases faster .
increasing eu content moves the mi transition to higher temperatures but preserves the behavior of @xmath37 vs @xmath38 at low temperatures .
a pronounced thermal hysteresis is frequently observed close to the mi transition indicating the first - order character of the transition , as discussed elsewhere [ 9 ] .
the @xmath9 data of ndnio@xmath18 indicate that an extra contribution to the ni sublattice must be considered below the magnetic ordering temperature @xmath17 .
therefore , to study the nio@xmath40 sublattice is necessary to perform a precise subtraction of the contribution of the rare - earth ions from the measured @xmath9 signal .
this kind of analysis has been done before , and indicated that the nio@xmath40 sublattice displays features of an unconventional antiferromagnet [ 9 ] .
in fact , @xmath9 still increases with decreasing temperature below @xmath17 , a behavior attributed to the existence of an inhomogeneous ground state comprised of alternating diamagnetic and paramagnetic sites [ 10 ] .
similar behavior of @xmath9 has been observed in the eu substituted samples studied here [ 9 ] and may have their counterpart in thermal properties , as described below .
the @xmath36 data , measured under the warming process for several samples , are displayed in fig .
1 . a well defined jump in @xmath36 at high temperatures identifies the mi transition of the samples , that varies from @xmath21 195 to 295 k for samples with @xmath41 and 0.35 , respectively .
in addition , samples with @xmath42 and 0.35 exhibit a positive @xmath43 in the entire range of temperature whereas those with @xmath41 and @xmath44 display a negative @xmath43 in a small temperature range below @xmath10 . at temperatures close to @xmath14

the inset displays the low temperature data accompanied by the best fits obtained by using the relationship @xmath45.,title="fig:",scaledwidth=80.0% ] considering a simple model where the system is comprised of non - interacting particles , @xmath36 can be expressed by the sum of two contributions : a phononic @xmath46 and an electronic @xmath47 component . at low temperatures ,
@xmath47 can be neglected ( insulating phase ) and @xmath48 can be expressed as @xmath49 , where @xmath50 is the heat capacity , @xmath51 is the drift velocity , and @xmath52 is the mean free path of the thermal carriers [ 11 ] . since @xmath52 and @xmath51 are expected to be temperature independent in the low temperature regime , @xmath36 would follow the @xmath53 behavior , i. e. , @xmath54 .
attempts to fit the low temperature @xmath36 data to a @xmath55 function have failed , even when an extra linear term was considered .
nevertheless , the best fits were obtained by using @xmath45 , depicted in the inset of fig .
1 , with values of @xmath56 and @xmath57 shown in table 1 . the factor @xmath56 follows a trend and decreases systematically with increasing eu content , whereas @xmath57 was found to be @xmath58 .
the function is essentially quadratic and the fits start to deviate from the experimental data when the temperature is increased above @xmath59 k. a @xmath60 term for @xmath36 is expected when phonons are scattered by electrons .
however , this seems to be improbable here since these samples are insulating at low temperatures [ 8 , 9 ] .
another possible origin for a @xmath60 term is due to the presence of itinerant magnetic excitations ( magnons ) , although this contribution would be effective only at very low temperatures [ 11 ] .

the low temperature @xmath36 would be mainly governed by phonon - defect scattering , being proportional to @xmath60 .
the presence of disorder in these nickelates has been proposed before and may to be related to the variable range hopping ( vrh ) mechanism observed in @xmath35 data at low temperatures [ 13 ] .
disorder can be an intrinsic property of the insulating phase of these compounds , as inferred from extended x - ray - absorption fine structure ( exafs ) in ndnio@xmath18 .
it has been proposed that a co modulation only occurs in a short range scale , but the system remains disordered in long range scale [ 14 ] . within this scenario , the insulating state , below @xmath10 ,
is better described as composed of insulating co and jahn - teller distorted pockets .
the effect of lowering temperature below @xmath10 favors the growth of the insulating pockets .
in addition to this , the absolute values of @xmath36 are rather small at low temperatures ( @xmath63 w / km at @xmath64 k ) , indicating that phonons are strongly suppressed .
such a behavior seems to be consistent with an inhomogeneous ground state due to cooperative bond - length fluctuations [ 15 ] .
some of the features described above were also observed in thermopower @xmath12 data , as shown in fig .
2 .
above @xmath10 , @xmath12 is negative and varies linearly with temperature , indicating negative charge carriers and a metal - like behavior , respectively .
when @xmath10 is reached , an abrupt change in @xmath12 takes place .
the inset of fig .

such a thermal hysteresis is suppressed in samples with eu content higher than @xmath65 ( not shown ) .

the inset displays the thermal hysteresis observed at the mi transition for the sample with @xmath41,title="fig:",scaledwidth=80.0% ] the low temperature behavior of @xmath12 is much more complex and two different regions are of interest . in the range 40 k @xmath66 ,
@xmath12 is negative , reaches @xmath67 v / k ( for @xmath68 0 ) , and displays a well defined minimum at a given temperature @xmath69 k. similar minimum has been observed in ndnio@xmath18 at @xmath70 k , below which @xmath12 approached zero [ 16 ] .
such a behavior is not expected in insulators , where @xmath12 would diverge as temperature is lowered . below @xmath71 , @xmath12 decreases and becomes positive at @xmath21 40 k. in the range @xmath72 k , @xmath12 is positive , indicating positive charge carriers , shows a sharp , large , and positive @xmath21 500 v / k peak at @xmath73 20 k. such a peak at @xmath15 has been found to be eu - independent and its shape does not follow the expected phonon - drag behavior , i. e. , @xmath55 for temperatures below the peak and @xmath74 for temperatures above .
the magnitude of @xmath12 depends on the eu - concentration , displaying a systematic decrease with increasing eu content . in order to better understand the role of the magnetic degrees of freedom in the electronic properties of these compounds ,
the pristine sample was subjected to an external magnetic field of @xmath75 koe .
figure 3 shows the @xmath3 data for two different magnetic fields during the warming cycle .
the @xmath3 data are magnetic field independent for @xmath76 k. in the low temperature region ( @xmath77 k ) , @xmath12 is enhanced by @xmath78 when a magnetic field of 90 koe is applied , although the temperature where the maximum occurs is also magnetic field independent .
[ htp ] temperature dependence of the thermopower of ndnio@xmath18 compounds under two applied magnetic fields .
the inset displays details of the increase of the maximum at @xmath14 k with increasing magnetic field , title="fig:",scaledwidth=80.0% ] the results for @xmath2 ( not shown ) indicated that the thermal transport is not affected by the external magnetic field , further suggesting that the only one contribution to @xmath2 arises from the lattice . on the other hand , the change of the sign of @xmath12 below 50 k ( see fig .
3 ) suggests a competition between two types of carriers and , consequently , an inhomogeneous ground state .
such a ground state can be visualized as composed of at least two kinds of regions ( or pockets ) with different charge carriers and different properties under applied magnetic fields .
as the shape of @xmath3 is essentially unchanged under application of magnetic fields , one of these regions is believed to be very sensitive to the magnetic field and its thermopower properties are largely enhanced .
we also mention that the nature of the phase responsible for the large magnetothermopower observed here is certainly related to the complex magnetic behavior of the ni sublattice below @xmath17 and the magnetic ordering of the nd ions at low temperatures [ 5 - 7 ] . in any event ,
neutron diffraction measurements at low temperatures are underway in order to clarify this point .

– Unwed momhood has rarely looked so good. Bristol Palin is following in her mom's footsteps with a lucrative speaking contract. A Palin family lawyer confirms to AP that Bristol has signed up with the Single Source Speakers and will receive up to $30,000 per engagement.

Palin also has a book in the works about her experience on the campaign trail in 2008, and her life as a single mother. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Bristol Palin is hitting the speakers' circuit and will command between $15,000 and $30,000 for each appearance, Palin family attorney Thomas Van Flein said Monday. Van Flein confirmed a report by celebrity news website RadarOnline that the daughter of former Alaska Gov. Sarah Palin has signed with Single Source Speakers. He added her exact fees will depend on factors such as which group she's addressing and what she must do to prepare. Bristol Palin, 19, is listed on the speaking group's website as available for conferences, fundraisers, special events and holidays, as well as women's, youth, abstinence and "pro-life" programs. Her fee is denoted by four question marks, meaning "Call to discuss!" The same designation is given to New Orleans Saints quarterback Drew Brees. A message left late Monday for Ron Miller, with Single Source Speakers, was not immediately returned. Bristol Palin was thrust into the spotlight as a pregnant teen during her mother's unsuccessful campaign for vice president in 2008. She had son Tripp that year and has since spoken about abstinence and the challenges of life as a young single mother. Van Flein said Bristol Palin will be selective in the speeches she gives. He said he believes she's interested in expanding her message beyond teen pregnancy to include her experiences on the campaign trail and in the media spotlight; her parenting approach; and her outlook on life.

– Yes, those were wedding bands worn by Natalie Portman and her guy, Benjamin Millepied, that lit a buzz at the Oscars. They're made with "recycled platinum and conflict-free diamonds," spilled jeweler Jamie Wolf, who designed the wedding rings for the 30-year-old actress and choreographer, 34. The platinum band is for Millepied, and Portman sports two diamond rings on either side of her engagement ring, notes People. Wolf, a dancer pal of Millepied, also designed Portman's engagement ring. The couple met on the set of the Black Swan, and announced late last year that they would marry.

– A California woman went to bury her dead pet and instead dug up a mystery—literally. The Modesto woman began digging in her backyard on Saturday afternoon when she hit on something that seemed to be human bones. The Stanislaus County Sheriff's Department verified the remains were indeed human, and detective subsequently exhumed what KCRA describes as a "decomposing body." Fox40 reports it's believed the remains have been there for several months at a minimum. Law enforcement says the woman had a connection to the house but hadn't been a resident for long. An identification and cause of death are pending. The Modesto Bee reports the property holds a small secondary residence in the back, and the tenant, who has been there a year, said he was unaware of the remains.

"When we have a case like this we investigate it as though it's a homicide until we figure out that it's maybe something different," said Sgt. Tom Letras. "So the first part of the process is removing the body. Once the body is removed, it's taken to our coroner's facility where an autopsy will be done." The autopsy will determine if the body found was that of a man or a woman. Then deputies can begin to see if they match any missing persons reports and go from there.

– Irritated by the proliferation of stray cats and dogs? Just move to Utah, where soon you’ll be able to take care of the problem … by shooting them. The Stir points to a new law being proposed by Rep. Curt Oda, a Republican who wants to legalize the killing of all feral animals. Of course, in order for the killing to be legal, the person doing it must be reasonably certain the animal is truly wild, and not just someone’s wandering pet. And if you don’t have a gun, no worries: clubbing, decapitation, or use of a bow and arrow would also be perfectly okay. Oda justifies the law by claiming it’s the cheapest and fastest solution to the homeless animal problem, but his idea has, not surprisingly, sparked a bit of an uproar amongst animal rights organizations, ksl.com reports.

But there is something very, very wrong with a new law being proposed by a republican legislator in Utah. He is sponsoring a bill that would legalize the shooting of all feral animals, on sight. It calls for: the humane shooting or killing of an animal if the person doing the shooting or killing has a reasonable belief that the animal is a feral animal. Reasonable belief? What exactly is that and who is regulating the guy on the corner to make sure he isn't just shooting his neighbors dog because it is off its leash? A feral animal is any domesticated animal that "has returned to live in wild conditions." So all of those homeless cats you see roaming around ... or abandoned dogs ... they are the animals Republican Representative Curt Oda is talking about. He says this is the cheapest and quickest way to get rid of, essentially, the homeless pet population in Utah. And he may be right, but there are advocate groups like No More Homeless Pets in Utah, that say he is wrong and have employed other methods to cope with the overpopulation of these animals. This proposed law is over-the-top, especially since the animal doesn't even have to be noticeably aggressive or sick to be shot. It just has to be considered, by the shooter, to be feral. It seems terribly dumb to give rights to every person in the state to shoot or kill these animals by way of clubbing, decapitation, or a bow and arrow. Yes, you read that correctly. I mean, if you can't afford a gun you should be able to participate too! The bill also includes the rights to kill rodents and other "pests" such as pigeons. Listen, I've never jumped on Bert's love for pigeons, but that doesn't mean they should suffer a clubbing. Are you as outraged by this as I am? Image via peyri/Flickr |

– An 18-year-old in California faces charges of vehicular manslaughter in a crash that killed her younger sister—and a key piece of evidence against her may be an Instagram video she was livestreaming before, during, and after the crash, reports KFSN. Police also accused Obdulia Sanchez of drunk driving. The Stockton teen was driving a car that veered off a road Friday and overturned, according to the California Highway Patrol. Her 14-year-old sister, Jacqueline Sanchez, was killed after being ejected, and another 14-year-old was badly injured but is expected to survive. Police say both were in the back seat, and neither girl was wearing a seatbelt. "I f------ killed my sister," Sanchez says in the video. "I know I'm going to jail for life ... I don't f------ care at all." At another point, she says, "If you don't survive, baby, I am so f------ sorry. ... I did not mean to kill you, sweetie. Sweetie, I am f------ sorry. Sweetie, please, wake up!" per the Washington Post. BuzzFeed has a link to the video, but note the graphic content. It's no longer on Instagram, but the CHP is examining it as part of its investigation, per the AP. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | NEW: Family members say the suspect, Obdulia (Lula) Sanchez just graduated from high school in October. pic.twitter.com/VOL98UsEyP — Sontaya Rose (@SontayaRose) July 24, 2017 An 18-year-old Stockton woman is in jail accused of driving under the influence during a deadly crash Friday.

(AP) — An 18-year-old woman has been arrested in California on suspicion of causing a deadly crash that she recorded live on Instagram. Obdulia Sanchez was booked into the Merced County Jail on suspicion of DUI and vehicular manslaughter after Friday's crash that killed her 14-year-old sister and badly injured another 14-year-old girl. The California Highway Patrol says Sanchez was driving the car when it veered onto the right shoulder of a road about 120 miles (190 kilometers) southeast of San Francisco. It says she overcorrected, causing the vehicle to swerve across lanes, crash through a wire fence and overturn into a field. Relatives confirmed to KFSN-TV (http://abc30.tv/2tSlnpX) that Sanchez was livestreaming on Instagram before, during and after the crash. The California Highway Patrol is examining the video as part of the investigation. |

– A laundry list of high-level staffers at Backpage.com are facing money laundering and facilitating prostitution charges, with one top executive now agreeing to testify against the rest of them. Per the AP, CEO Carl Ferrer has struck a plea deal in which he'll admit guilt to state and federal conspiracy and money laundering charges, as well as help prosecutors go after his former colleagues at the classified-ad site, which itself has pleaded guilty to human trafficking and money laundering charges, per Texas AG Ken Paxton and a newly unsealed plea agreement. Ferrer, 57, will face no more than five years behind bars in Arizona. Any prison time Ferrer is hit with would run concurrently with five-year sentences already received in California and Texas as part of what the Washington Post is calling Ferrer's "three-state guilty plea tour." "For far too long, Backpage.com existed as the dominant marketplace for illicit commercial sex," Attorney General Jeff Sessions said in a statement. Ferrer's name wasn't on an indictment unsealed Monday against seven Backpage officials, including co-founders Michael Lacey and James Larkin, per the Post. Lacey and Larkin are currently behind bars in Arizona and charged with facilitating prostitution; they've pleaded not guilty to those federal charges, as well as to California state money-laundering charges. In his plea deal, Ferrer said he'd "conspired with other Backpage principals" to circumvent state prostitution laws, creating a "veneer of deniability for Backpage" by editing keywords out of ads that would've raised red flags. One contingency to Ferrer's plea deal: He has to help the government shut down Backpage.com, per the Arizona Republic. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Backpage.com Pleads Guilty to Human Trafficking in Texas Thursday, April 12, 2018 – Austin Attorney General Ken Paxton announced today that his office’s prosecution of Backpage.com has resulted in the company pleading guilty to human trafficking in Texas and its CEO Carl Ferrer pleading guilty to money laundering. This comes less than a week after the attorney general’s office assisted the Department of Justice with permanently shutting down the website. Ferrer will be sentenced to up to five years in prison once he’s fulfilled the terms of his plea agreement with Attorney General Paxton’s office. His cooperation in the ongoing investigation into Backpage could lead to other criminal charges against individuals associated with the company. As the largest online sex trafficking marketplace in the world, Backpage facilitated the sex trafficking of innocent women and children through sites it ran for 943 locations in 97 countries and 17 languages. It was involved in 73 percent of all child trafficking cases reported to the National Center for Missing and Exploited Children. “Taking down Backpage and obtaining a criminal conviction for the company and its CEO represents a significant victory in the fight against human trafficking in Texas and around the world,” Attorney General Paxton said. “I want to thank the Attorney General of California, the U.S. Department of Justice, federal law enforcement officials, Nueces County District Attorney Mark Gonzalez, and the prosecutors and law enforcement in my office for their outstanding collaborative work on this investigation and prosecution.” In October 2016, Attorney General Paxton’s Law Enforcement Division arrested Ferrer in Houston. It also executed a search warrant on the Dallas headquarters of Backpage, uncovering evidence that was critical in building a case against Ferrer and the company. Attorney General Paxton has made combating human trafficking a top priority. Two years ago, he launched his office’s Human Trafficking and Transnational/Organized Crime Section, which prosecutes human traffickers around the state of Texas. Earlier this year, he unveiled a powerful training video to teach Texans how to spot and report suspected human trafficking activity. President Trump yesterday signed the Allow States and Victims to Fight Online Sex Trafficking Act of 2017 into law, making it easier for law enforcement to take legal action against any websites that enable human trafficking. View Attorney General Paxton’s statement on Backpage here: https://bit.ly/2IHoE31 ||||| SACRAMENTO, Calif.—The chief executive of a website that authorities have dubbed an “online brothel” pleaded guilty Thursday to state and federal charges including conspiracy and money laundering. He also agreed to testify in prosecutions against others at Backpage.com, authorities said.

contributions to the energy levels in light muonic atoms and , in particular , to the lamb shift fall into a few well - distinguished classes .
the related diagrams are calculated using different approaches .
in particular , there is a specific kind of non - relativistic contributions .
here we consider such corrections to the lamb shift in order @xmath0 .
these contributions are due to free vacuum polarization loops as well as to various effects of light - by - light scattering .
the closed loop in the related diagrams is an electronic one , which allows a non - relativistic consideration of the muon .
both kinds of contributions have been known for a while , however , the results obtained up to date are only partial ones .
we complete a calculation of the @xmath0 contributions for muonic hydrogen .
the results are also adjusted for muonic deuterium and muonic helium ion .
recent progress of the psi experiment on the lamb shift in muonic hydrogen @xcite has attracted interest to theory of the lamb shift in light muonic atoms . their study can provide us with information on certain nuclear structure effects with accuracy that is not available in any other experiment . to obtain such data
, one has to be able to separate quantum electrodynamics ( qed ) effects from the nuclear structure effects , and for this purpose an adequate qed theory providing high accuracy is required .
contributions to the energy levels in light muonic atoms and , in particular , to the lamb shift fall into a few different well - distinguished classes .
a specific theory stands behind each of them .
there are corrections , the evaluation of which is identical for hydrogen and muonic hydrogen , and corrections that are specific for muonic atoms .
the latter involve a certain part of qed , recoil effects and effects of the finite nuclear size .
an important class of such specific contributions , which , in fact , also include the dominant term for the lamb shift , is due to non - relativistic physics .
we remind that atomic momenta in light muonic atoms @xmath1 are compatible with the electron mass , while the atomic energy @xmath2 is much smaller than the electron mass .
( the relativistic units in which @xmath3 are applied throughout the paper . )
such an environment produces an important sector of corrections , which deal with a non - relativistic bound muon , while the qed effects are present only through the closed electron loops .
meanwhile the compton wave length of electron @xmath4 determines the radius of the effective interaction induced by this kind of diagrams .
the loops may be for either free - loop vacuum - polarization ( vp ) effects , related to the uehling , kllen - sabry potential and higher - order diagrams , or the to light - by - light ( lbl ) scattering contributions .
the vp leading term is of order @xmath5 and it has been known for a while , while the second - order vp contribution ( of order @xmath6 ) was calculated with appropriate accuracy for muonic hydrogen in @xcite only relatively recently .
the accuracy of current and planned experiments requires a complete theory of non - relativistic contributions to the lamb shift in order @xmath0 .
the lbl contributions are depicted in fig .
[ fig : lbl ] , while the vacuum polarization diagrams are present in fig .
[ fig : vp ] . both kinds of contributions have been known for a while , however , the results obtained up to now were only partial ones .
in particular , in the case of muonic hydrogen the contribution in fig . [
fig : lbl]@xmath7 has not yet been calculated , while there are also some questions @xcite about applicability of the so - called scattering approximation applied in @xcite to evaluate the contribution in fig .
[ fig : lbl]@xmath8 .
certain lbl contributions have specific names .
the first one in fig .
[ fig : lbl ] is a so - called wichmann - kroll contribution and it was calculated for muonic hydrogen with sufficient accuracy in @xcite .
it was also reproduced in @xcite ; we also confirm this contribution . for muonic deuterium and muonic helium-4 ion
the results have been obtained in @xcite and we confirm the deuterium result @xcite and obtain a result for a muonic helium ion @xmath9 which is consistent with @xmath10mev of @xcite , but more accurate , and strongly disagrees with @xmath11mev of @xcite . in our calculation
we used approximations for the wichmann - kroll potential in the form @xmath12
\nonumber\end{aligned}\ ] ] as discussed in @xcite ( see also @xcite ) and @xmath13 as considered in @xcite and @xcite . here
@xmath14 .
the results are consistent .
indeed , if higher accuracy is required , one can apply an exact expression @xcite for @xmath15 as a two - dimensional integral . the second term ( fig .
[ fig : lbl]@xmath8 ) is called ` virtual - delbrck - scattering contribution ' .
it has been calculated for muonic hydrogen in @xcite .
the calculation was based on @xcite , where at first a scattering approximation was applied and subsequently a number of further approximations was made .
we remind that the scattering approximation suggests that the external muon legs in the diagram in fig .
[ fig : lbl]@xmath8 are on - shell ( i.e. @xmath16 ) and the muon propagator there is substituted for a free one , i.e. , the kinematics is exactly the same if one calculates a related born scattering amplitude . since atomic momenta @xmath17 in light muonic atoms are compatible with the electron mass @xmath18 , the validity of such an approximation is questionable ( see , e.g. , the discussion in @xcite ) .
we , however , have proved that the scattering approximation is applicable within the uncertainty of order @xmath19 ( in fractional units ) , which is at the level of about 1% in muonic hydrogen and deuterium and of about 4% in muonic helium .
that is also correct for other simplifying approximations , which were made in the calculations for this contribution in light muonic atoms @xcite .
a general idea of our evaluation is presented in appendix [ s : a ] , while the details of our evaluation are to be published elsewhere @xcite .
eventually , we conclude that the uncertainty of the method applied in @xcite is substantially smaller than the uncertainty of the related numerical evaluations for the lamb shift correction in muonic hydrogen @xcite , muonic deuterium @xcite and muonic helium-4 ion @xcite .
the contribution in fig .
[ fig : lbl]@xmath7 has no specific name .
since any other lbl contribution has one ( ` wichmann - kroll term ' and ` virtual - delbrck - scattering contribution ' ) , sometimes it is referred to as a ` light - by - light contribution ' , which is somewhat confusing
. this contribution has remained uncalculated for a while .
studying applicability of the scattering approximation for the diagram in fig .
[ fig : lbl]@xmath8 , we have also managed to prove @xcite that this remaining contribution can be expressed in terms of the well - known wichmann - kroll term @xmath20 the uncertainty of this identity is of order @xmath19 ( in fractional units ) , which is at the level of about 1% in muonic hydrogen and deuterium and of about 4% in muonic helium . by combining our results on the uncertainty of various approximations with the numerical results of other authors ,
we obtain the complete result for all lbl contributions of fig .
[ fig : lbl ] .
the result is listed in the summary table ( table [ t : sum ] ) . with identity
( [ 3:1 ] ) proved and a possibility to obtain a result for the wichmann - kroll ( @xmath21 ) with high accuracy for any light muonic atom , the uncertainty in the calculation of the complete lbl contribution now comes from the virtual - delbrck - scattering term , which should determine the eventual uncertainty of the non - relativistic @xmath0 term for muonic hydrogen , deuterium and helium - ion . another major non - relativistic contribution in order @xmath0 is due to vacuum polarization contributions .
the vp terms of this order were studied for muonic hydrogen in @xcite .
the diagrams are depicted in fig .
[ fig : vp ] , which includes contributions of the first ( fig [ fig : vp]@xmath22@xmath23 ) , second ( fig [ fig : vp]@xmath24 ) and the third ( fig [ fig : vp]@xmath25 ) order of non - relativistic perturbation theory ( nrpt ) .
the most complicated terms are indeed related to the first line of fig .
[ fig : vp ] , however , these diagrams were cross - checked due to their contributions to the anomalous magnetic moment of muon @xcite and we can rely on them .
the contributions of the second line of fig .
[ fig : vp ] are specific for muonic atoms and do not correlate directly with any calculation for the muon @xmath26 .
those have been recalculated completely independently of @xcite , as well as part of diagrams in the first line .
we confirm the second - order terms of nrpt , while our result @xcite for the third - order term ( the last diagram in fig .
[ fig : vp ] ) disagrees with the one originally published in @xcite .
after a correction @xcite their result agrees with ours . in our calculations we used techniques developed while investigating second - order vacuum - polarization contributions to the hyperfine structure of muonic hydrogen @xcite .
.the non - relativistic qed contributions to the lamb shift @xmath27 in light muonic atoms : hydrogen ( h ) , deuterium ( d ) , helium-4 ion ( he ) , which includes vp contributions of the first ( @xmath5 ) , the second ( @xmath6 ) and the third @xmath28 ( fig .
[ fig : vp ] ) order as well as a complete lbl contribution .
the latter is a sum of contributions of order @xmath29 ( fig .
[ fig : lbl]@xmath22 ) , @xmath30 ( fig . [ fig : lbl]@xmath8 ) and @xmath28 ( fig . [ fig : lbl]@xmath7 ) .
results marked with @xmath31 are obtained in this work.[t : sum ] [ cols="^,^,^,^ " , ] the diagrams in fig .
[ fig : vp ] were also discussed in various papers in the context of the lamb shift in muonic deuterium @xcite and muonic helium-4 ion @xcite . for this purpose a part of the contributions
was recalculated there . here , we reevaluated all the vacuum - polarization contributions and the results are listed in table [ t : sum ] . comparing with the paper mentioned we have to acknowledge that our results are not in complete agreement with theirs . in @xcite
only contributions of fig .
[ fig : vp]@xmath22 and @xmath8 were directly calculated for muonic deuterium and the results for them agree with ours . however , that result were not applied there but instead the muonic - hydrogen result was ` re - scaled ' .
that was achieved by assuming that the result for muonic hydrogen , presented in @xcite in the form of @xmath32 where @xmath33 is the muon reduced mass , can be directly applied for the muonic deuterium .
that has not been claimed in @xcite and is indeed incorrect and the value of the coefficient @xcite @xmath34 is valid only for muonic hydrogen ( cf . with @xmath35 from @xcite , which needs a correction @xcite as explained above ) .
the related values for other light muonic atoms , obtained here , @xmath36 obviously differ from ( [ c3hyd ] ) .
the muonic - helium-4 paper @xcite lacks a complete result and only a part of diagrams of fig .
[ fig : vp ] were recalculated .
our results are not in fair agreement , and in particular we strongly disagree in the contribution of fig .
[ fig : vp]@xmath37 for muonic helium . in the wichmann - kroll contribution ( fig .
[ fig : lbl]@xmath22 ) we also strongly disagree with the result @xcite , while we agree with the result @xcite , for which we obtain higher accuracy ( see ( [ wk : he ] ) ) . finally , we summarize in table [ t : sum ] a complete theory of non - relativistic qed contributions to the lamb shift in muonic hydrogen , deuterium and helium ion up to the order @xmath0 ( see @xcite for references to the calculation of the low - order corrections ) .

– Usher is playing a big show in London next week, and he wants you to join him onstage. Kind of. Concert sponsor American Express has set up a website where anyone can choreograph a dance sequence using an avatar. Submit the sequence, and it could be chosen for display during the concert, marked with your name and city, Mashable reports. The avatar's gender, moves, colors, speed, and more are under the user's control. "Everybody wants to be part of the show and now they can," says director Hamish Hamilton. The Monday concert will be live-streamed on YouTube. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Pop star Usher is looking for new backup dancers — virtual ones — for his upcoming London concert, which will be live-streamed June 11 from Hammersmith Apollo. Starting Friday, fans can create digital avatars of themselves to win the chance of becoming a choreographed dance square during Usher's performance of "Scream." American Express teases the interactive element in the above video, shared first with Mashable. The show is part of the American Express Unstaged concert series, which began in 2010 and has since attracted almost 100 million live stream views on YouTube and Vevo for artists such as Coldplay, Sugarland, Duran Duran and Arcade Fire. Each concert pairs an artist with a well-known director (such as John Legend with Spike Lee, Mary J. Blige with Adam Shankman and Jack White with Gary Oldman). For Usher's live-streamed concert, renowned director Hamish Hamilton — the mastermind behind Madonna's Super Bowl halftime show and the 82nd Academy Awards — will spearhead the creative direction. “Usher's concert will be equally fantastic — if not better — on camera than in person." "Everybody wants to be part of the show and now they can," Hamilton tells Mashable, adding that his cameras will be strategically placed to capture Usher's passion, sweat and dance moves. Twenty-five of Usher's dance moves from choreographer Aakomon Jones were recorded, digitized and turned into visual "particles" to produce silhouettes for fans to customize. Hamilton and his team tapped Moment Factory to generate the digital dancers. During the performance, Usher will be able to single out individual dancers or dance with thousands at once. The dancers will be projected onto large LED screens. Fans can customize the dancers into millions of different combinations of moves, colors and more, making each one unique by gender, dance moves and sequence, animation type (speed and flow), color, first name and city. "It's one thing to create something, it's another thing to caputre it and make it make sense for the television (online) domain," Hamilton stresses. "Usher's concert will be equally fantastic — if not better — on camera than in person." The concert also features an interactive social media element. Some Twitter users' tweets containing #AmexUNSTAGED will appear in a visual installation that is reactive to Usher’s dance movements. "(Hamilton) is among the best in the industry when it comes to bringing high-energy, visually stunning music performances to fans who are watching at home," Deborah Curtis, AmEx's VP of entertainment marketing and sponsorships, tells Mashable. BONUS: Jay-Z Rocks SXSW at AmEx Twitter Event Additionally on the music front, American Express had rapper Jay-Z take the stage at South by Southwest during an event to promote its new Twitter-based discounts program. |

– Justin Bieber and others with a $250,000 reservation to board Virgin Galactic's tourist spaceship won't have too much longer to wait. Richard Branson tells CNBC that commercial space test flights will begin in "weeks, not months," forging a path for the Virgin founder to board SpaceShipTwo himself "in months and not years." The 68-year-old billionaire—who's undergone astronaut, centrifuge, and fitness training—adds the company will begin taking travelers to space "not too long after." The current ticket price is $250,000, though Branson says it could fall to as low as $40,000 over the next decade. Per the BBC, Jeff Bezos' Blue Origin firm plans to launch a manned space mission by 2019. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Image copyright Rob Kim Entrepreneur Sir Richard Branson has said that Virgin Galactic is "weeks" away from its first trip into space. "We should be in space within weeks, not months. And then we will be in space with myself in months and not years," the firm's founder and chief executive told news website CNBC. He said the firm would be taking people into space "not too long after" that. Sir Richard is in a race with Elon Musk and Jeff Bezos to send the first fee-paying passengers into space. He founded the commercial spaceflight company in 2004. The company first promised sub-orbital spaceflight trips for tourists by the start of 2009. But delays and a fatal crash in 2014 prevented Sir Richard's original ambitions. Earlier this year, Virgin Galactic completed a supersonic test flight of its SpaceShipTwo passenger rocket ship, its first since the crash. The 67-year-old multi-millionaire was initially expected to take part in a space flight before April this year. High demand In an interview with BBC Radio 4's You and Yours programme, Sir Richard said he was receiving astronaut, centrifuge and fitness training. He also insisted there was huge demand for commercial space flights. "If I have a room full of 10 people, eight out of 10 would love to go to space if they could afford it," Sir Richard told CNBC. "It is up to us to produce as many spaceships as we can to cater with that demand." His announcement comes shortly after rival SpaceX unveiled the first private passenger it plans to fly around the Moon.

– The charges keep piling up for Harvey Weinstein: The 66-year-old disgraced movie mogul pleaded not guilty Monday to more sexual assault allegations, reports the Daily News. Weinstein's previous legal trouble involved alleged assaults on two women, and Monday's charges add a third woman. Prosecutors say Weinstein performed oral sex on her without her consent in 2006. If convicted of the latest offense, he faces a minimum of 10 years and a maximum of life in prison. "Mr. Weinstein maintains that all of these allegations are false and he expects to be fully vindicated," said defense attorney Ben Brafman outside court, per the AP. Brafman added that he expected more charges to follow. Weinstein, who was brought into the Manhattan courtroom in handcuffs, was released on bail after pleading not guilty.

(Associated Press) NEW YORK (AP) — Harvey Weinstein, who was previously indicted on charges involving two women, was released on bail on Monday while fighting sex crime accusations that now include a third woman. "We fight these battles one day at a time, and today we won this round," defense attorney Ben Brafman said outside court. Brafman said during an arraignment that he expects more charges. Weinstein pleaded not guilty after he was brought into the courtroom while handcuffed from behind, then uncuffed for the proceeding. An updated indictment unveiled last week alleges the movie mogul-turned-#MeToo villain performed a forcible sex act on a woman in 2006. The new charges include two counts of predatory sexual assault, which carries a maximum sentence of life in prison upon conviction. Manhattan District Attorney Cyrus R. Vance Jr. said the 66-year-old Weinstein is charged with "some of the most serious sexual offenses" that exist under state law. "Mr. Weinstein maintains that all of these allegations are false and he expects to be fully vindicated," Brafman said. More than 75 women have accused Weinstein, who was one of the most powerful men in Hollywood, of wrongdoing as allegations detailed in Pulitzer Prize-winning stories last October in The New York Times and The New Yorker magazine swelled into the #MeToo movement. Several actresses and models accused Weinstein of criminal sexual assaults. They include: film actress Rose McGowan, who said Weinstein raped her in 1997 in Utah; "Sopranos" actress Annabella Sciorra, who said he raped her in her New York apartment in 1992; and the Norwegian actress Natassia Malthe, who said he attacked her in a London hotel room in 2008. Weinstein, who produced movies including "Pulp Fiction" and "Shakespeare in Love," has denied all allegations of nonconsensual sex, with his attorney challenging the credibility of his accusers. The Associated Press generally does not identify people who say they are victims of sexual assault unless they come forward publicly. ||||| "He's obviously a man of substantial resources . . . it shouldn't be too much of a pull for him to arrange for him to have a home here in Manhattan, and he should only be allowed to leave his home here in Manhattan for doctor's appointments or other emergency services," Illuzi said. |

– Kate Gosselin failed to impress at her Dancing With the Stars debut—and it turns out she’s just as awful off the dance floor as on. “Kate shows up late for hair and makeup every time,” an insider tells the New York Daily News, and when confronted about it by staff, she “just gets angry and blows them off. No one wants to deal with her.” The source—clearly not a member of Team Kate—adds that the reality show mom probably won’t get the votes, either. “Kate tried to appeal to the housewife vote by saying, ‘This is for all the moms out there!’ But really, what kind of mom leaves their kids at home for a dance competition?” If Kate does find herself in the bottom two, she has eight little strategies for gaining the sympathy vote—for more on that, click here. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Drama! 'Dancing with the Stars' insider says Kate Gosselin is always late for hair and makeup Larkey/ABC A 'Dancing with the Stars' insider says Kate Gosselin is notorious for being late to hair and makeup. There's already been drama along with the dips on this season's "Dancing With the Stars": Sources say that despite the lineup of known prima donnas like Shannen Doherty and Pamela Anderson, it's Kate Gosselin who's causing the trouble. The worst of the reality TV mom's antics? Her out-of-control tardiness. "Kate shows up late for hair and makeup every time," a show insider says of the rehearsals that led to Monday night's opener, which drew a record-breaking 22.8 million viewers. A rep for the ABC program says, "Kate is always on time and is a pleasure to work with," but the insider begged to differ. "The staff has warned her and lectured her about being late, but Kate just gets angry and blows them off," says the source. "No one wants to deal with her." While such behavior may be expected from the notoriously short-fused Gosselin, the spy says the "Dancing" staff initially feared that former "Beverly Hills 90210" star Doherty would be the troublesome hoofer. "Everyone had heard the stories of Shannen's behavior on sets when she was younger," says the source. "But she's been one of the easiest people to work with. She's practically the opposite of Kate." The same can be said for their onstage performances. While Shannen did well on the show's premiere, Kate tanked. In fact, the judges placed her third to last with a score of 16 out of 30, putting her just in front of 80-year-old former astronaut Buzz Aldrin. It's not just her pliés that Kate may be having trouble with. Our insider says the demographic she's trying to impress just isn't going to buy it. "Kate tried to appeal to the housewife vote by saying, 'This is for all the moms out there!'" sneers the source. "But really, what kind of mom leaves their kids at home for a dance competition?" ||||| A whopping 24 million viewers tuned in for Monday's premiere of 'Dancing With the Stars.' Much of that attention was, let's face it, due to the curiosity of watching Kate Gosselin do her thing. Among those watching was, who visited HLN's 'The Joy Behar Show' last night to give his take on Kate's so-called "disaster" of a night. Not only does Rob not think Gosselin will go home any time soon, he thinks, "She's gonna win this show."Rob also says, "A friend of Kate's told me that if she thinks she's gonna be in the bottom two, expect eight little faces to be in the front row next week!" |

– Yesterday was the 44th anniversary of Yoko Ono's marriage to John Lennon, and she marked the occasion by offering a personal—and graphic—statement on the gun-control debate: She tweeted a photo of Lennon's bloodstained glasses. "Over 1,057,000 people have been killed by guns in the USA since John Lennon was shot and killed on December 8, 1980," reads the text accompanying the image, which she rapidly tweeted a total of four times. "We are turning this beautiful country into a war zone," she wrote. "After 33 years our son Sean and I still miss him." The photo was also used on a 1981 album cover, notes the Telegraph. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The photograph of the glasses the Beatle was wearing when he was shot dead on 8 Dec 1980 carries a message reminding people that, since then, more than a million people have been killed by guns in the USA. She sent the image out four times in quick succession yesterday, on the 44th anniversary of their marriage. The image was retweeted more than 8,000 times. The artist and peace activist, 79, claimed that guns were turning the country into a warzone. In one of the tweets accompanying the image she wrote: “The death of a loved one is a hollowing experience. After 33 years our son Sean and I still miss him. Yoko Ono Lennon.” One of her tweets repeated the message that was superimposed on the moving image, reading: “Over 1,057,000 people have been killed by guns in the USA since John Lennon was shot and killed on 8 Dec 1980.” While the others said: “31,537 people are killed by guns in the USA every year. We are turning this beautiful country into war zone. “Together, let's bring back America, the green land of peace.” The image of his glasses with Central Park in the background was also featured on the cover of her 1981 album Season of Glass, her first solo recording after Lennon was killed by Mark Chapman. The couple were married in Gibraltar on March 20, 1969, and went on honeymoon to Amsterdam, where they famously campaigned for peace by spending an entire week in bed. The gun debate in America was reignited following the Sandy Hook shootings in December last year. Ono’s calls for peace came just a day after hopes of a US assault weapon ban faded as Democrat Senate leaders dropped the proposal from a gun control bill expected to be tabled next month. ||||| Tweet with a location You can add location information to your Tweets, such as your city or precise location, from the web and via third-party applications.

– Without discovering a satisfactory explanation for her death, police have closed the investigation into a woman who suffocated beneath the sand of a Maryland beach, WTOP reports. "How the hole collapsed, she unfortunately is the only person that will know," Ocean City Police Chief Ross Buzzuro says. Ashley O'Connor of Texas was vacationing in Ocean City with her family when she went for a walk on the beach alone around 2am July 31. The 30-year-old's body was found more than four hours later when a passerby noticed her hand sticking out of the sand. A medical examiner said O'Connor died from asphyxia due to suffocation, and her death was ruled accidental with no possibility of foul play, according to WBAL. Police believe O'Connor climbed into the 3.5-foot-deep hole in the sand on her own for an unknown reason. She had been drinking and was found to have a BAC more than the legal limit for driving. It's unclear who made the hole or why it collapsed. O'Connor, who was found in a sitting position at the bottom of the hole, may have caused the collapse herself when she climbed in, or tractors in the area may have caused it. But WJLA reports a tractor driver told police he hadn't seen a hole in that area of the beach, and it may have already collapsed. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The death of a Texas woman on an Ocean City beach on July 31 has been ruled accidental, and investigators have been unable to determine what caused a hole she climbed into to collapse, burying her alive. On Thursday, police said Ashley O' Connor, 30, was intoxicated and walking on the beach, when she climbed into a three to four foot deep hole to sit down to smoke a cigarette. O' Connor's body was later found on a beach on 2nd Street, and her cause of death was asphyxia due to suffocation, according to the Ocean City Police Department. A tractor driver told police he did not see a hole on the beach where she climbed in, and said it may have already been filled in. An initial investigation by police revealed that O' Connor was walking on the beach alone when she was later found in a hole covered by sand. Authorities at the time were trying to determine if she fell into the hole or climbed inside of it on her own. In a separate incident at an Ocean City beach on Aug. 1, Timothy Thompson, 35, died after he was caught in a rip current. Rescue swimmers jumped in and began a search to recover Thompson's body, but it was too late. Police say he died at an area hospital. ||||| The death of a 30-year-old woman whose body was found buried in an Ocean City beach has been ruled accidental, police said. Ashley O’Connor, of Plano, Texas, was found on the beach in the early morning hours of July 31 in the area of 2nd Street, police said. She was vacationing at Ocean City. Detectives determined that O’Connor walked alone onto the beach in the area of 2nd Street around 2 a.m. and sat in a hole approximately 3 to 4 feet deep. At one point, the hole collapsed while O’Connor was inside, ultimately causing her death, police said. Detectives were unable to conclusively determine what caused the hole to collapse, but found no evidence of foul play, police said. The Office of the Chief Medical Examiner ruled the death to be accidental caused by asphyxia due to suffocation, police said. "We're not sure what happened after Ashley walked on to the beach between 2:15 and 6 a.m., but we've ruled out foul play. We are not 100 percent sure, and probably never will be, but this was a tragic accident," Ocean City Mayor Rick Meehan said. Because the death was ruled to be accidental, a comprehensive toxicology report will not be completed; however, the autopsy revealed that alcohol was a factor in the incident, police said. |

– We could soon have some "new" Charles Dickens to peruse. Researchers are preparing to pore through the manuscripts of Dickens' novels using a device that reveals what the author crossed out, the Independent reports. That allows scholars to experience the novelist "almost thinking aloud on to paper," says a museum curator. They've already used the process on his story The Chimes, but there's much more to explore. "We're talking of tens of thousands of manuscript pages that could potentially be unlocked," says the head of the Charles Dickens Museum in London. The device uses an electrically-lit, 1 mm-thick sheet that illuminates a manuscript page. After a photograph is snapped, a computer "removes" the top layer to reveal the hidden text, the Telegraph reports. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The new technique allows researchers to discover how the author shaped and reshaped his prose. The Victoria & Albert Museum pilot study focused on his Christmas story, The Chimes, using technology developed by Ian Christie-Miller, a former visiting research fellow at London University. Although no dramatic revelations emerged from deletions in that short story, scholars are excited by the technology's potential on novels such as Bleak House. Florian Schweizer, director of the Charles Dickens Museum in London, told The Independent: "We're talking of tens of thousands of manuscript pages that could potentially be unlocked." The technology, separating layers of text, involves combining two or more digital images – a frontlit and backlit image of a page. By digitally subtracting one from the other, differences are revealed. In The Chimes, the tests showed for example that the published sentence – "Years … are like Christians in that respect" – originally read: "Years … are like men in one respect." Dr Schweizer said: "Why did he make that change? Quite a change. Literary scholars will ask themselves those questions." Rowan Watson, a senior curator at the V&A, described Dr Christie-Miller's technology as "ingenious and inspiring". The manuscripts show Dickens "almost thinking aloud on to paper," he said. ||||| Following a pilot study on his short novel, The Chimes , at the Victoria and Albert Museum, researchers have decided that significant lost passages might be unlocked from the original manuscripts of his great novels, including Bleak House . The tantalising new technology did not produce any significant finds during the first crawl, besides a few interesting word changes. One sentence, “Years … are like Christians in that respect” originally read: “Years … are like men in one respect.” However, Rowan Watson, a senior curator at the V&A, described the technology in The Independent today as “ingenious and inspiring”. The manuscripts show Dickens “almost thinking aloud on to paper,” he said. Florian Schweizer, director of the Charles Dickens Museum, has said that Dickens was a furious scribbler and blotter, which means the material unearthed could be plentiful. “We're talking of tens of thousands of manuscript pages that could potentially be unlocked,” he said. Developed by Ian Christie-Miller, a former visiting research fellow at London University, the device illustrates the hidden work with the use of a special 1mm-thick sheet, which produces a bright light when an electric current is passed through it. This lights the page from behind and it is then photographed and computer software is used to strip out the image on the front. The light was used in 2006 to successfully reveal damaged sketches by the renowned 18th century architect Robert Adam, which had been lost for more than a hundred years. |

– Call it the tamer (and more romantic) version of the Mile High Club, before the plane even left the ground. The Independent reports on an airline pilot who decided to surprise his flight attendant girlfriend, who works with him, two days before Christmas. As Jon Emerson, 24, gave passengers weather, altitude, and turbulence details before their SkyWest flight took off from Detroit to Oklahoma City, he suddenly changed the subject. He introduced 23-year-old Lauren Gibbs as his girlfriend, and also as "one of our very best flight attendants," then said he wanted her to not only remember this day as their anniversary, but also as a "day to be known for the rest of our lives." In a video Gibbs posted to her Facebook page, Emerson can then be seen whipping out a ring box and getting down on one knee in front of Gibbs to offer his marriage proposal amid clapping and cheers from the flight's passengers. (Emerson headed back to the PA system to note, "She said yes" for those who couldn't hear in the back.) "I got to say the easiest YES of my life to my best friend!" Gibbs writes in her post. "It still feels like a dream and I cannot explain how blessed I am to spend forever with Jon." She included the hashtag #LaurenLandedEmerson, then added a bit of news about the venue for their nuptials: "Sorry to disappoint, but the wedding will not be on a plane!" (Another holiday season proposal, this one in subzero temperatures.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | See more of Lauren Michele Emerson on Facebook ||||| When flight attendant Lauren Gibbs boarded the plane to Detroit to Oklahoma City just before Christmas, she already knew it was a special day. Gibbs, 23, from Nashville, Tennessee, would be in control of the cabin, while her boyfriend, pilot Jon Emerson, was on the flight deck. Not only that, but it was their anniversary. But she was in for a surprise when Emerson, 24, made the pre-flight announcements to the cabin. After informing them about the flight time (2 hours 30 minutes), altitude (36,000 feet) and likelihood of turbulence (“a few light bumps in the air”), Emerson got personal. Introducing Gibbs to the cabin, he said: “This is a very special day for Lauren and me. It’s our anniversary today and she’s one of our very best flight attendants.” He went on: “I want this day to be known for the rest of our lives. I want to spend the rest of my life with her.” He then whipped out an engagement ring, got down on one knee and asked her to marry him. The answer was an enthusiastic yes, and the whole thing was filmed by an off-duty pilot sitting in first class, whom Emerson had primed in advance. “I was caught so off guard,” Gibbs told The Independent. “Jon is a really quiet guy, with a very shy personality so for him to do it in front of passengers was so not like him, but for me it was perfect and so thoughtful. We spend almost all of our time together on planes and working together so the timing and place was absolutely perfect.” The couple – who asked The Independent not to name the airline they work for – met when they were assigned a trip together, and have flown together ever since, turning their long layovers into “mini vacations”. Emerson and Gibb met on a flight and have been together ever since (Lauren Gibb) “The best thing about having a pilot as my significant other is always having someone there after a long day of working,” Gibbs told The Independent. “Layovers can be really boring so always having someone there with me makes the experience so much better.” Emerson had spent the past three months planning the proposal for their 23 December anniversary, he said. So will the wedding be onboard a plane? “I think Jon would absolutely love to have planes involved for our wedding,” says Gibbs. “However we will probably have something more quiet and smaller for our friends and family.” The planning has yet to start, though, so there’s always time to change her mind.

– A female black bear and four yearling cubs who have been making a living Dumpster diving in Anchorage will get a new home—and not that great trout stream in the sky, thanks in part to the actions of Alaska Gov. Bill Walker. As the Alaska Dispatch News reports, Walker yesterday intervened to plead for the lives of the quintet, which were set to be euthanized, by asking the state Fish and Game commissioner if there was another solution. "I’m sure there will be plenty of criticism about the governor getting involved in this," Walker said. "But I’m a person too. I have a soft spot for individuals in circumstances not of their own making." The bears will now likely be trapped and transported about 60 miles away, so as to inhibit their return. "I'm here in Juneau being inundated with budget issues and having to say no to all these programs," Walker continues. "I felt these bears had done nothing wrong and just thought it was the right thing to do." Speaking of those budget issues, the Fish and Game chief says it won't be too pricey to move the bears—but don't expect relocation to replace euthanasia as the norm. "There are a lot of bears so it would be expensive if you had somebody doing it full time," he says. Both men underscore that it was a request from Walker that resulted in "a collective decision," per KTUU, not an order. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The seed for this crawl was a list of every host in the Wayback Machine This crawl was run at a level 1 (URLs including their embeds, plus the URLs of all outbound links including their embeds) The WARC files associated with this crawl are not currently available to the general public. ||||| JUNEAU - UPDATE: The Department of Fish and Game has reconsidered its decision to kill the five bears that frequent Government Hill, officials wrote in a press release, Saturday evening. "After receiving waves of requests from the public to spare the sow and her four yearling cubs, Gov. Bill Walker and the department made a collective decision today to instead relocate the bears," officials wrote. According to the release, relocating bears has not always been a good option. A trash-eating bear that was killed last year on the University of Alaska Anchorage campus, had previously been relocated to a remote area near Eklutna, though she returned to Anchorage with her cubs, shortly after. ORIGINAL STORY: A family of trash-eating bears that made headlines as they traipsed around Government Hill is getting a stay of execution from Alaska’s governor. Department of Fish and Game officials said earlier this week there was no choice but to kill the five black bears that have been wandering around the Anchorage neighborhood due to the cost involved with relocation, potential diseases that may result, and the complexities of finding a welcoming home. However, Gov. Bill Walker said Saturday from the Capitol — amid the frenetic close to the 90-day lawmaking session — that he found a minute to contact Fish and Game Commissioner Sam Cotten to instruct them to take another approach. Walker said he was concerned when he saw news reports that the bears could be put down. “I've been following it, watching it,” he said. “I just think this is the season that we can give them another try elsewhere. I really didn’t think the bears had done anything wrong.” Grace Jang, the governor’s spokeswoman, said the department will make another attempt to relocate the animals but will keep public safety as the top priority. Fish and Game officials previously said the city needs to deal with its garbage problem to prevent future incidents where bears are put down due to public safety concerns. Residential areas known to be frequented by bears often have no bear-proof trash cans: “If we can deal with the bear garbage attraction situation properly, they’ll still be around but you won’t see them as much,” said Sean Farley, a research biologist.

– It was only a matter of time. A 39-year-old man has come forward claiming to be Prince's "sole surviving heir" after the music superstar died last month, seemingly without a will, ABC News reports. According to WCCO, Carlin Williams of Kansas City is the first person to claim to be Prince's son. He says his mother met Prince in a Missouri hotel in 1976, drank wine with him, then had unprotected sex, TMZ reports. She says she didn't have sex with anyone else within six weeks of her tryst with the musician. Williams, who is currently in prison in Colorado on a weapons conviction, filed paperwork requesting a DNA test to confirm his claim on Monday.

Add as an interest to stay up to date on the latest news, video, and analysis from ABC News. Add Interest Carlin Q. Williams filed paperwork in a Minnesota probate court today, in which he requested DNA testing. His also petitioned to be determined as the late singer's "the sole surviving heir." Prince died late last month at the age of 57, and afterward, his sister, Tyka Nelson, filed paperwork stating that she did not believe he had a will. As a result, Bremer Trust has been appointed to manage the music legend's estate. Last Friday, a judge authorized Bremer Trust to have Prince's blood genetically analyzed should any possible heir present him or herself. In an affidavit filed today, Williams' mother, Marsha Henson, claimed that she met Prince in July of 1976 at a hotel in Kansas City, Missouri. Shortly thereafter, she claimed in the affidavit, they had sexual intercourse and conceived a son. Nine months later, she gave birth to Carlin Q. Williams on April 8, 1977, she added.

– A camper at Yosemite National Park left his site with his wife Sunday morning to fetch coffee, but when they tried to return to their tent, they were met with the sight of an ambulance, a firetruck, and park rangers who wouldn't let them back into the area. The reason, per KFSN: A tree had fallen on a fellow camper and killed her, per the Mariposa County Sheriff's Office. A park spokesman confirmed to KCRA that the unidentified 21-year-old woman died after the tree toppled onto her tent around 11am at Half Dome Village in the California park. Park officials, who noted strong winds and heavy snow increase the chance of trees falling, shuttered the village and other camping areas afterward, with some not expected to be reopened until Monday afternoon.

– Maine dairy drivers who picked a court fight over grammar have an extra $5 million to show for their geekery, reports the AP. Oakhurst Dairy drivers settled their 2014 lawsuit last week for a relatively big pay day—they had originally sought $10 million—after a federal appeals court decided to keep the drivers' lawsuit alive last year. The suit concerned an exemption from Maine's overtime law that says it doesn't apply to "canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of" foods. An Oxford comma after "shipment" would have clarified the intent of the law, or as the plaintiffs' lawyer said earlier, "That comma would have sunk our ship." The state legislature has since amended the language to read thusly: "The canning; processing; preserving; freezing; drying; marketing; storing; packing for shipment; or distributing of," which the New York Times notes gives us the chance "to replace Oxford comma pedantry with semicolon pedantry." But alas, notes the Times, "the resolution means there will be no ruling from the land’s highest courts on whether the Oxford comma—the often-skipped second comma in a series like “A, B, and C”—is an unnecessary nuisance or a sacred defender of clarity, as its fans and detractors endlessly debate." (More on the case here.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | PORTLAND, Maine (AP) — A Maine dairy company has settled a lawsuit over an overtime dispute that was the subject of a ruling hinging on the use of the Oxford comma. Drivers with Oakhurst Dairy filed the lawsuit in 2014 seeking more than $10 million. Court documents filed Thursday show that they settled for $5 million. A federal appeals court decided to keep the drivers' lawsuit alive last year. The suit concerned an exemption from Maine's overtime law that says it doesn't apply to "canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of" foods. The disagreement stemmed from the fact there's no Oxford, or serial, comma in the "packing for shipment or distribution" part. The drivers said the words referred to the activity of packing and shipping, but they don't do any packing. ||||| It appears the Maine Legislature has learned its lesson, at least. It revised the disputed state law last year to end ambiguity by adding new punctuation — but not in the way you might be thinking. The case began in 2014, when three truck drivers sued the dairy for what they said was four years’ worth of overtime pay they had been denied. Maine law requires time-and-a-half pay for each hour worked after 40 hours, but it carved out exemptions for: The canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of: (1) Agricultural produce; (2) Meat and fish products; and (3) Perishable foods. What followed the last comma in the first sentence was the crux of the matter: “packing for shipment or distribution of.” The court ruled that it was not clear whether the law exempted the distribution of the three categories that followed, or if it exempted packing for the shipment or distribution of them. Had there been a comma after “shipment,” the meaning would have been clear. David G. Webbert, a lawyer who represented the drivers, stated it plainly in an interview in March: “That comma would have sunk our ship.” Since then, the Maine Legislature addressed the punctuation problem. Here’s how it reads now: The canning; processing; preserving; freezing; drying; marketing; storing; packing for shipment; or distributing of: (1) Agricultural produce; (2) Meat and fish products; and (3) Perishable foods. So now we get to replace Oxford comma pedantry with semicolon pedantry. The change, sponsored by Senator Andre Cushing, was among dozens of legislative tweaks signed by the governor in June. “It clarifies the intent of the legislature, to conform with federal law, that the distribution of certain products is exempt from the provisions governing overtime pay,” according to a summary of the changes. “It amends the 1995 law by reordering the series of exempt tasks for the purpose of eliminating any perceived ambiguity.” |

– As if the Secret Service didn't have enough to deal with just now, agents are meeting today with shoot-from-the-lip rocker Ted Nugent. They're concerned about his comments that he'll be "dead or in jail" if President Obama wins reelection, apparently indicating some kind of violence. During the meeting he intends to be as "polite and supportive as I possibly can be, which will be thoroughly," Nugent told Glenn Beck yesterday. "The bottom line is I've never threatened anybody's life in my life," Nugent added. "I don't threaten, I don't waste breath threatening. I just conduct myself as a dedicated 'We the people' activist." Nugent hasn't apologized for the apparently threatening comments, made at a National Rifle Association rally. But he is taking the Secret Service concern seriously.

"I will be as polite and supportive as I possibly can be, which will be thoroughly," Nugent told Glenn Beck on Wednesday. During a National Rifle Association convention last weekend, Nugent said, "If Barack Obama becomes the president in November, I will either be dead or in jail by this time next year." The U.S. Secret Service said on Tuesday that it was aware of Nugent's comments and would investigate.

I just conduct myself as a dedicated 'We the people' activist because I've saluted too many flag-draped coffins to not appreciate where the freedom comes from." The gun-loving "Cat Scratch Fever" singer has not apologized for the incendiary talk but added: "I'm not trying to diminish the seriousness of this, because if the Secret Service are doing it they are serious." On Wednesday, a defiant Nugent sounded off on the backlash. "This is the Saul Alinsky 'Rules for Radicals' playbook," Nugent said Wednesday on a CNN radio show. "The Nazis and the Klan hate me. I'm a black Jew at a Nazi Klan rally.

– Those who like to fish purely for the sport of it often abide by a "catch and release" policy: Reel in the fish, unhook it, and let it go free again to make sure stocks don't get depleted. But a first-of-its kind study suggests that what seems like a happy ending for both fish and fishermen isn't so great for the fish after all, reports BGR. Researchers at the University of California-Riverside found that fish caught with a hook in or near the mouth have a significantly tougher time feeding afterward, they report in the Journal of Experimental Biology. As in, the perch in the study sucked in food 34% slower than perch caught with a net, reports Discover. “We were surprised with how dramatic the difference was,” says lead researcher Tim Higham. The finding suggests that catch-and-release poses a risk to a fish's survival, but the researchers say more study is needed to determine whether this adds up to a "significant impact on survival." For example, they need to figure out if feeding improves as the injury heals. Still, if the results are confirmed, it could lead to changes such as smaller hooks or the rethinking of catch-and-release practices for rare fish, per Discover. (You probably don't watch to catch this fish in Oklahoma.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Catching fish for food is something that has been done for, well, pretty much since the dawn of mankind, but fishing as a hobby or sport is a relatively recent wrinkle. Sportsmen who fish simply for the enjoyment of it often adopt strict catch-and-release policies to ensure that fish populations remain robust, sustaining their pastime in the future. However, a new study published in the Journal of Experimental Biology suggests that the simple act of catching a fish may be enough to doom it to death, even if it is promptly returned to the water after being de-hooked. The study focused on the damage caused by hooks in the mouths of fish that were previously caught. When hooked, the tissue around the mouth of a fish is often damaged, sometimes severely. The long-held belief that fish don’t feel pain in the same way humans or some other animals do is often enough to assuage the guilt of tearing up the lip of a fish, but the study says that’s not the real problem. “Using high-speed video and computational fluid dynamics (CFD), we asked whether injuries around the mouth caused by fishing hooks have a negative impact on suction feeding performance,” the researchers write. “We hypothesized that fish with mouth injuries would exhibit decreased feeding performance compared with controls.” Well, as it turns out, their hypothesis proved to be true. The suction feeding mechanism used by many fish to suck in and secure prey is indeed hampered by injuries to the mouth caused by hooks. Fish with hook injuries are less reliable feeders, which might put their overall survival prospects at risk. “Fishing injuries in nature are likely to depress feeding performance of fish after they have been released,” the scientists say. While the focus of the study was on feeding performance, and the results are very clear, the actual impact on the survival of hook-injured fish was not followed. A subsequent study could shed more light on the overall impact on survivability of fish with hook injuries, but the fact that such wounds makes it significantly more difficult to eat suggests that the long-term results could be dire. ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

Volusia County Sheriff Mike Chitwood said authorities are relying on autopsy results. Heather Kelsey, 30, and her husband, Daniel Kelsey, 32, of Ormond Beach were found dead Saturday when a Florida Highway Patrol trooper spotted hazard lights on the couple’s SUV, authorities said. Daniel and Heather Kelsey “Right now, it's in the hands of the medical examiner. We have everything we have, but to determine the cause of death is what we are waiting for, and we are expecting to get that in the next day or two," Chitwood said.

– Zhao Wei, one of China's most famous actors, has an intense stare in her role as domineering matriarch in the TV show Tiger Mom. In fact, she's so intense that a viewer is now suing her, claiming he has suffered "spiritual damage" from the evil eye she's giving him through his TV set, Sky News reports. The lawsuit has likely made its way into the system as the result of a law passed May 1 in China that makes it harder for courts to turn down cases, the AP reports. The number of nationwide cases jumped 29% in May compared with the same period in 2014, the AP adds. A court manager said at a press conference yesterday that the staring lawsuit was exactly the type of case some had feared would take place once the law went through.

FILE - In this file photo taken Thursday, Aug. 28, 2014, Chinese actress Zhao Wei poses for portraits during the 71st edition of the Venice Film Festival in Venice, Italy. New rules enacted May 1, 2015... (Associated Press) The regulations making it more difficult for courts to reject lawsuits took effect May 1, leading to an increase in cases nationwide last month of 29 percent compared with same period last year, to just over 1 million cases, according to the Supreme People's Court. The registration system requires courts to accept legitimate lawsuits when they are filed or clearly state the reasons for rejecting them, and citizens have the right to appeal the decisions. "Previously, it was difficult for administrative cases, such as people suing governments, to be accepted," said Li Heping, a Beijing lawyer. In announcing the registration system, the official Xinhua News Agency said: "Authorities are determined to put an end to obstructive behavior by courts and officials meddling in cases." The change has led to Shanghai Pudong New District Court receiving a case against Zhao, the court's litigation service hotline confirmed. The court official, who declined to identify himself, refused to say whether the court had accepted the case. Zhao is one of China's biggest and richest movie stars, and starred in director John Woo's "Red Cliff." Reports say the lawsuit filed by a Shanghai man involves the prime-time TV show "Tiger Mom" which debuted in May and centers on a couple's differing approach to raising their daughter. Zhao plays the big-eyed mother who relentlessly pushes her daughter's development, while the father wants his child to have more freedom. The Legal Daily said the plaintiff was alleging Zhao's stare caused him "spiritual damage." Gan Wen, deputy head of a case-filing chamber under the Supreme Court, said at a news conference Tuesday that the Zhao case was an example of citizens abusing their right to file lawsuits. "It's not necessary to waste our judicial resources on cases like these," Gan said. |

– "For richer and for poorer, through broken-down cars and in health" is how Angelique Arsenault could have rewritten her vows after a pre-wedding roadblock in New Hampshire. The AP reports Arsenault was in her limo with her bridal party on Saturday, on her way to say "I do" in Milford, when suddenly the car came to a halt on a somewhat-deserted road in Brookline. "I'm like, 'It's fine. Maybe he just hit something,'" the maid of honor tells CBS Boston, adding that he then informed his passengers that the limo had a flat. The bridal party decided to take the incident in stride, indulging in some of the limo's champagne and then sticking their thumbs out to hitch a ride to the wedding ceremony and Jarrod Dunne, Arsenault's waiting fiance, at the Mile Away restaurant (which was actually seven miles away at that point). That's when a Good Samaritan named Jay pulled over with a car full of kids, heard their story, ran to drop the kids off, and returned to offer his chauffeuring services. The bride tells WCVB she arrived a half-hour late to the ceremony, but she says her wedding day still turned out to be "amazing."

(CBS) – When things went awry on Angelique Arsenault’s wedding day, the bride decided to take matters into her own hands.

Angelique had waited 11 years to marry her groom, but on a breathtaking Saturday afternoon, she quickly realized she was going to have to wait longer, because on the way to the ceremony, just five minutes from her house, the limo carrying her bridesmaids and family abruptly pulled over. “The limo driver gets out of the car, I’m like, ‘it’s fine. Maybe he just hit something,’” recalled Katie Queen, the maid of honor. “He gets back in, opens up the back window, and says, ‘you’ve a flat tire.’” The champagne helped. “We just laughed about it,” Angelique said. Russell Hill Road in Brookline, New Hampshire isn’t exactly well-traveled. “We actually had cars driving by us and they just took pictures and left and then finally someone actually stopped to see if we needed a ride,” Angelique said. The driver who stopped was a man named Jay. He had a car full of kids but he was determined to help. So he dropped them off, returned, and asked the bride, “where to?” He declined an on camera interview, but said he was just happy to help. The Mile Away venue wasn’t a mile away. It was seven rural miles away, where Jarrod Dunning was patiently waiting and worrying. Thirty minutes late, Angelique and her bridal party arrived. Now on her honeymoon, she realizes Jay didn’t just save her big day, he was the punctuation. “It pretty much made the whole day,” Angelique said. “Everyone was laughing all night about it. It’s going to be a story we’ll remember forever.” ||||| BROOKLINE, N.H. (AP) — After waiting 11 years to marry her groom, a flat tire wasn't going to stop a determined New Hampshire bride from walking down the aisle on her special day. With her limo rendered inoperable along an infrequently traveled road in Brookline, Angelique Arsenault stuck out her thumb and hitchhiked to the wedding venue in nearby Milford on Saturday. Arsenault says her bridal party just laughed after receiving word of the flat tire from their driver. With confidence fueled by champagne, Arsenault in her white dress was able to flag down a passing motorist who gladly helped get her to the altar — albeit 30 minutes late. Despite the small hiccup, Arsenault says the rest of her wedding was "amazing" and she now has a story her family will remember forever. |

– Human beings can only see around 30 shades of gray, according to a bit of trivia Popular Science says it found in a research paper and has decided to share "for no particular reason whatsoever." The exact number of shades of gray we can distinguish will vary a little depending on things like lighting conditions, the magazine says. Meanwhile, in Fifty Shades of Grey news, a theater in Loveland, Colo., accidentally showed the beginning of the erotic thriller to an audience expecting the SpongeBob SquarePants movie earlier this week. "People ran out of there," a moviegoer tells the Denver Post. "You could hear little kids going, 'SpongeBob! SpongeBob!' as the parents were dragging them out." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The seed for this crawl was a list of every host in the Wayback Machine This crawl was run at a level 1 (URLs including their embeds, plus the URLs of all outbound links including their embeds) The WARC files associated with this crawl are not currently available to the general public. ||||| Loveland theater accidentally starts R-rated movie in place of kids' flick This image released by Paramount Pictures and Nickelodeon Movies shows characters, from left, Squidward Tentacles, SpongeBob SquarePants, Sandy Cheeks, and Mr. Krabs in a scene from "The Spongebob Movie: Sponge Out of Water." ( Paramount Pictures and Nickelodeon Movies via Associated Press ) WATCH DPTV: Molly Hughes with today's top stories "SpongeBob GreyPants." Or maybe "Fifty Shades of SpongeBob." Joe Jaramillo of Johnstown sat in the MetroLux 14 theater Monday morning with his granddaughter waiting for "The SpongeBob Movie: Sponge Out of Water" film to start. He noticed that the previews all seemed to have a romantic flavor but didn't think much of it until the movie started and the words "Fifty Shades of Grey" appeared on screen. "People ran out of there," Jaramillo said with a laugh. "You could hear little kids going, 'SpongeBob! SpongeBob!' as the parents were dragging them out." He said after a few seconds, the screen abruptly went blank. Then new trailers started rolling, this time with children's themes. While "SpongeBob SquarePants" is about an underwater sea creature and all his silly antics, "Fifty Shades of Grey" is an R-rated erotic romance movie based on a book by the same name. Jaramillo said he was thankful that from what he has heard, the adult themes in "Fifty Shades" don't begin until later in the movie. "What was interesting is they have the policy you can't take a kid into an R-rated movie," Jaramillo said. "Some of the trailers were coming up R-rated." David Corwin, president of Metropolitan Theatres, said that there was a chip problem with the server and somehow the wrong movie started playing. Advertisement "It stopped pretty quickly. Someone came out to tell the staff and they stopped it," Corwin said. "Fortunately, the beginning (of 'Fifty Shades') is pretty scenic. It was obviously not intended." He said that both movies are played in that auditorium at different times; "SpongeBob" during the day and "50 Shades" at night, which means the films are on the same computer server. Digital theaters project digital files onto a screen, unlike older film projectors. Corwin added that the theater managers handle every situation differently. In this case, no free passes were issued because the situation was resolved quickly and without undue harm to the children.

the arecibo l - band feed array zone of avoidance survey ( alfa zoa ) will map 1350 - 1800 @xmath0 at low galactic latitude , providing hi spectra for galaxies in regions of the sky where our knowledge of local large scale structure remains incomplete , owing to obscuration from dust and high stellar confusion near the galactic plane . because of these effects , a substantial fraction of the galaxies detected in the survey will have no optical or infrared counterparts .
however , near infrared follow up observations of alfa zoa sources found in regions of lowest obscuration could reveal whether some of these sources could be objects in which little or no star formation has taken place ( `` dark galaxies '' ) .

– Another big setback for Uber: The Justice Department is in the early stages of a criminal investigation of the company over the "Greyball" program it used to avoid regulators as it expanded its service across America, sources tell Reuters and the Wall Street Journal. Users "greyballed" by the software were shown a fake version of the Uber app and found themselves unable to get rides. Uber used it in cities such as Portland, Ore., to avoid sting operations while the service was banned there. Uber, which stopped using Greyball after a New York Times report exposed it, claims the software was mostly used to test new features and to protect drivers. Sources say that to help Uber drivers avoid regulators, the system tried to identify government workers and law enforcement officers by looking for government-issued credit cards, checking social media profiles, and putting a "geofence" around government buildings, Gizmodo reports. According to Reuters' sources, the company has already received a subpoena from a grand jury in Northern California seeking records related to its use of the software. (A new law has forced Uber to cease operations in Denmark.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Reuters is reporting tonight that Uber faces a criminal investigation by the Department of Justice for using software to avoid scrutiny by government regulators. In March, the New York Times’ Mike Isaac reported the existence of the “Greyball” software, used to “identify and circumvent officials who were trying to clamp down on the ride-hailing service.” Government officials whose job involved regulating Uber were tagged as “greyballed” and “served up a fake version of the app,” in which fake cars appeared on the app and drivers quickly canceled. Advertisement It used a variety of signifiers, at least a dozen, to figure out who was a government official, including using social media, identifying credit cards tied to institutions like police credit unions, and drawing a “geofence” around government buildings on its maps. Uber employees would even “go to local electronics stores to look up device numbers of the cheapest mobile phones for sale, which were often the ones bought by city officials working with budgets that were not large.” A few days after Isaac’s story was published, Uber said it would no longer use the software to avoid government scrutiny. Uber did not respond immediately to Gizmodo’s request for comment. Reuters reports that Uber received a subpoena from a Northern California grand jury, “seeking documents concerning how the software tool functioned and where it was deployed.” That means the company is under criminal investigation, though it doesn’t necessarily mean charges will be brought. Advertisement The news is just the latest instance of an almost uniformly terrible year for Uber, which has seen allegations of widespread internal sexual harassment, an ongoing court battle with Google over its self-driving car unit, a campaign to get users to delete their accounts, and a leaked video of its CEO Travis Kalanick berating a bankrupt driver. It’s not even the only creepy tracking program that was revealed this year: it also used a program literally named Hell to track Lyft drivers. Uber has built a good deal of its success, and its estimated $68 billion valuation, on ignoring, avoiding, and fighting government regulations, from the California DMV to treating its drivers as actual employees; and, more broadly, on the philosophy that being a “brilliant jerk” is a good thing. This probe is the latest evidence that approach might not work forever. ||||| Federal prosecutors have begun a criminal investigation into Uber Technologies Inc.’s use of software that tricked local regulators who were trying to identify drivers in sting operations, according to a person familiar with the investigation. Through a program called “Greyball,” Uber was able to hide its drivers by showing government officials dummy versions of its app with fake cars trawling the streets. Uber has said it used the technology to evade government officials seeking to identify and block the service’s drivers... |

– It has been a bad week for kids in Texas, with three shootings involving children under 10 years old, one of them fatal, taking place in the space of four days, Raw Story reports. On Wednesday, a five-year-old shot his seven-year-old brother with an old rifle while the two played unsupervised in the bath. On Thursday, a two-year-old fatally shot himself in the head with his dad's handgun, while his father was busy elsewhere in the room, says Raw Story. And yesterday, an eight-year-old shot his five-year-old friend in the head with a rifle, as the two played alone in a bedroom. The boy is in a critical condition in hospital, the Denton Record-Chronicle reports. Two of the guns used were .22-caliber rifles, similar to the one with which a five-year-old accidentally killed his two-year-old sister in Kentucky earlier this month. The grandfather of the children spoke out this week, saying his grandson was too young to have a gun and that it was a cultural problem in rural Kentucky. "Too many people think it's (guns) for target practice. Well, what comes after target practicing—killing. I know, I was in the Marine Corps," he told the Star Democrat. “When you pick this (gun) up, you're usually going to kill something." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | 8-year-old boy shoots 5-year-old friend with found rifle By Arturo Garcia Saturday, May 11, 2013 21:57 EDT A 5-year-old boy in Denton, Texas was reportedly in critical condition on Saturday after an accidental shooting involving an 8-year-old friend. KXAS-TV reported that the two boys were alone in a bedroom when the 8-year-old found a .22-caliber rifle and pointed it at the younger boy. Police said the older boy then accidentally shot his friend in the left side of his head. Two adults, including the 5-year-old boy’s grandfather, and a teenager were also inside the home at the time of the shooting. The younger boy was first taken to a local medical facility, then transported by air to Children’s Medical Center in Dallas, Texas. KTVT-TV reported that he was on a ventilator as of Saturday evening. “It’s a very tragic accident, especially the day before Mother’s Day,” said Denton Police spokesperson Orlando Hinojosa. “Education is the most important thing about firearm safety. Just make sure your children know, if you do have weapons in the house, where they’re at, and for them not to be reachable.” This incident is the third shooting involving children in Texas this week, and the second involving a .22-caliber rifle. On Tuesday, Houston officials said a 5-year-old boy was handling one when he accidentally shot his 7-year-old brother while the two were taking a bath. And on Wednesday, a 2-year-old boy in Corsicana shot himself in the head with his father’s handgun. Watch KXAS’ report on the accidental shooting in Denton, aired Saturday, below.

Webster Thursday, May 9, 2013 12:07 EDT A two-year-old boy from Corsicana, Texas, a town of just under 24,000 people located between Dallas and Waco, shot himself in the head Wednesday night with his father’s handgun while his dad was looking away, police said. The victim was identified as Kinsler Allen Davis, according to The Associated Press. Davis was rushed to the local hospital in Fredricksberg before medics put him on a life flight to Dallas, but even doctors there could not save him. A police statement obtained by Dallas-based CBS DFW explained that all physical evidence so far in the case indicates the shooting was accidental. The boy found his 35-year-old father’s handgun while the man was interacting with something in his bedroom’s closet, with his son just feet away. “As you can imagine, they’re extremely upset and distraught,” Corsicana police chief Randy Bratton reportedly said.

Ramon Perez is apologizing after handing out a document to the House Finance Committee that showed open tabs on a computer with pornographic content. The Providence Democrat brought the printout to a committee meeting Wednesday night, in which he testified on an automobile crash protection bill he sponsored. What he handed out was a screen grab of a Wikipedia entry for the Puerto Rico Automobile Accident Compensation Administration. Several open tabs were visible with titles that referenced obscene material. One tab included the word "teen." The screen grab was time stamped at 2:07 a.m. On Friday, Perez took to Facebook to apologize, saying someone else sent him image, which he included in his post. Reached by phone Friday evening, Perez said that he did not notice the words on the tabs before he shared the information. “It was a mistake, and I recognize that,” he said, in an interview conducted in Spanish. “My fault.” He asked rhetorically why he would have shared the screen grab publicly had he seen the words. Asked who shared the information with him, Perez said, “I won’t mention anything, because it’s my fault,” adding that person was only trying to help him. House spokesman Larry Berman confirmed that Perez gave the document to the clerk of the Finance Committee who made copies and distributed it to committee members. Once the words in the tabs were discovered, the clerk quickly collected the document. Perez has since printed a version of the article that does not include the pornographic references and resubmitted it as testimony, Berman said. State police hadn't received any complaint about Perez's post as of Friday afternoon, according to spokeswoman Laura Meade Kirk. Perez is a first-term representative. He replaced former Rep. John Carnevale, who was forced off the ballot last year after failing to convince canvassers that he lived in his district. — With reports from staff writer Amanda Milkovits |

Family is remembering Tyler Grisham as a devoted husband and father to his 2 young daughters. "He was one in a million," said Grisham's Father-in-law Wade Boughner. "Whatever you needed Tyler was there." Boughner says his family's world shattered when they got the news. "He was here one minute and then just blink of an eye he's gone. He never even had a chance," Boughner said. Grisham died at a local hospital early Saturday morning. Family says the Cabot native was doing contract work for RedStone Construction Friday afternoon when lightning hit a tree he was standing near. "They said that they just couldn't do anything, that the lightning strike had wreaked too much havoc on his body," Boughner added. The job site off Coronado Cove in Maumelle was quiet Saturday. Neighbors like Jim Thompson in shock over what happened in their backyards. "It was a loud boom, almost like a bomb," Thompson said. "We looked out the front and we could see some of the workers, we could see them scurrying around a little bit." Thompson says the storm moved in quickly, but he can't stop wishing he could have done more to help." "People don't realize how quickly you can be here and be gone in a matter of seconds," he added.

– If some guy in Pennsylvania says he's got a bridge to sell you, he may mean it literally. Thieves made off with an entire steel bridge in (very) rural Pennsylvania, reports WTAE as noted by Gizmodo. It measures, or measured, 50 feet by 20 feet, and would likely fetch about $100,000 in scrap metal. The bandits likely needed torches and a few days to pull off the caper in North Beaver Township. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Police in North Beaver Township, Pennsylvania are scratching their heads right now. Why? A 50-foot long, 20-foot wide steel bridge just disappeared. How? Apparently, some very bold criminals just up and stole it. Advertisement Stealing a bridge, as you'd imagine, is a pretty complicated crime. This isn't some 90s era magic trick people. The local police suspect that the bridge robbers worked at this for over a month. They presumably used a blow torch to cut the corrugated steel and then somehow moved the pieces—steel beams and such— to sell for scrap metal. That couldn't have been easy as each foot was estimated to weigh hundreds of pounds. But why oh why would you even bother stealing a bridge? Because the scrap metal is estimated to be $100,000. Oh. But even knowing how it happened, I'm still left wondering, how does this happen!? It's a crime that's so far out there that no one really knows what from how and who from why. In fact, police say the bridge went missing some time between September 27th and October 5th. That's a pretty long range for something that big to go missing, right? Advertisement And who in the right mind would look at a bridge and go hey, I think I can take that down. How do they transport it? Who are they selling it to? And how come no one noticed earlier? (this has a more reasonable answer, it's deep in the woods and the bridge is an old railroad bridge). Will they re-build the bridge? Were the robbers really there for a month? Are they going to steal another one? Is this going to set off a bridge stealing bonanza? Hey, I'd actually like that. Life would be more exciting if more bridges got stolen. Robbing bridges is the new black.

– A new documentary about Kurt Cobain will debut next year on HBO, and this one has a twist—the singer's daughter, Frances Bean Cobain, will be executive producer, reports Entertainment Weekly. The documentary by Brett Morgen is billed as the first film about Cobain authorized by his family, though Pitchfork notes that the press release makes no mention of widow Courtney Love. Morgen says the documentary will make clear that Cobain was not just a singer but a talented "visual artist." The title will be Montage of Heck, a name Cobain himself gave to a mix tape he made at age 21. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Two years after airing Brett Morgen’s Rolling Stones documentary, Crossfire Hurricane, HBO has signed up to air his long-simmering documentary on Kurt Cobain. The Nirvana frontman died in 1994 at the age of 27 and has been the subject of many books and films since, including other documentaries like 1998’s Kurt & Courtney and 2006’s Kurt Cobain: About a Son. Morgen’s been working on his documentary, Kurt Cobain: Montage of Heck, for over five years and says he hopes the film will show Cobain fans that the man wasn’t only the face of Nirvana. “The thing about him people might not know too is that he was an incredible visual artist and left behind a treasure chest of comic books, paintings, Super 8 films, all sorts,” Morgen told Fact in 2013. “We are going to do the movie sort of like a third-person autobiography, as if Kurt was around and making a film about his life.” Frances Bean Cobain, Cobain and Courtney Love’s daughter, is executive producing. The film will debut on HBO and Universal will release the film internationally in 2015. ||||| An unseen image of Kurt Cobain at home, featured in the film Kurt Cobain: Montage of Heck, © The End of Music, LLC/courtesy HBO HBO has announced that filmmaker Brett Morgen's Kurt Cobain documentary Montage of Heck will premiere on the premium cable channel next year. Though Montage of Heck is the latest in a long line of Nirvana/Cobain films—most notably, AJ Schnack and Michael Azerrad's About a Son—the film is being billed as the first "fully authorized" one. It was made with participation from Kurt Cobain's family. In fact, Frances Bean Cobain, Cobain's daughter with Courtney Love, is attached as executive producer. (There is no mention of Love in the press release, however.) Montage of Heck takes its name from a mixtape Cobain made in the late 80s. The documentary features "dozens of Nirvana songs and performances as well as previously unheard Cobain originals," according to a press release, in addition to "no-holds-barred access to Kurt Cobain’s archives, home to his never-before-seen home movies, recordings, artwork, photography, journals, demos, personal archives, family archives and songbooks." In the press release, Morgen said: I started work on this project eight years ago. Like most people, when I started, I figured there would be limited amounts of fresh material to unearth. However, once I stepped into Kurt’s archive, I discovered over 200 hours of unreleased music and audio, a vast array of art projects (oil paintings, sculptures), countless hours of never-before-seen home movies, and over 4000 pages of writings that together help paint an intimate portrait of an artist who rarely revealed himself to the media. HBO currently airs the miniseries Sonic Highways, directed by Cobain's former bandmate Dave Grohl. Watch Nirvana's video for "Come As You Are": |

– Envy jolly old St. Nick: He gets to do all his flying tonight. Americans planning to fly home the day after Christmas, on the other hand, might be in trouble. A huge storm system that has already dumped rain and snow on the West Coast should hit the Midwest and East Coast just in time to muck with travel plans, ABC News reports. By Wednesday the Midwest will likely be blanketed by snow, which could cause delays at airports in Chicago, Cleveland, Detroit, and St. Louis. The National Weather Service is also warning of a "risk for a significant severe weather outbreak on Christmas Day" across the southeastern US, including possible tornadoes in the Lower Mississippi River Valley. By Thursday, the Northeast on one end and Florida on the other will get their turn. Of course, West Coast residents have already been through all this; more than 400 flights were cancelled yesterday in San Francisco alone. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Sorry, the location you searched for was not found.

Please select one of the following: ||||| A huge storm that dumped heavy snow and rain on the West Coast is expected to move east and could spoil travel plans for people looking to return home the day after Christmas, which is considered one of the busiest travel days. The powerful storm that has already blanketed much of Northern California is expected to move east over the next few days and drop snow from Oklahoma starting today before finishing up in the Northeast sometime Wednesday. The Midwest will be covered with snow by Wednesday, likely causing delays at major airports in cities including Cleveland, Detroit, St. Louis and Chicago just in time for post-Christmas travel, when millions of Americans will be on the move. Snow could arrive in the Northeast by Thursday, dropping 1-3 inches over parts of New England. In Syracuse, N.Y., plows are working overtime, dealing with two consecutive days of snow this weekend during the city's first snowstorm of the season. As the city continues to dig out, all eyes are watching the storm roll in from the west. Torrential rain and heavy winds have also caused trouble for California's Bay Area over the weekend, which has seen severe flooding, power outages and delays for those planning to fly out for the holidays. Ryan Damstra of Northern California spent seven hours at San Francisco's International Airport Sunday but was not able to fly. "After I found out my flight had been canceled after four hours of waiting in the airport, I had to wait another three hour customer service line," Damstra told ABC News Radio. More than 400 flights were canceled on Sunday at San Francisco International Airport. Travelers had to deal with more than 200 cancelations on Saturday. So far this month San Francisco got almost five inches of rain that is almost twice as much as they get for the entire month of December. Severe snow and rain are not the only issues facing Americans looking to get home before the New Year. Several states in the Gulf of Mexico all the way from Houston to Raleigh, N.C., are bracing for possible tornadoes starting today and lasting until Wednesday. The biggest chance for tornadoes will be tomorrow from Houston to New Orleans to Birmingham and Atlanta. AAA predicts 93.3 million people will travel more than 50 miles this holiday season, from Saturday through New Year's Day. That's a 1.6 percent increase from last year. Christmas is the third-busiest holiday for travelers, after Memorial Day and Thanksgiving. AAA is urging drivers to leave earlier or later to dodge bad weather.

– As protesters took to the streets with renewed ferocity in Syria today, roughly two-thirds of the country’s Internet networks abruptly disappeared from global routing tables, Bloomberg reports. As of this morning, 40 of the country’s 59 networks were unreachable. One state-run site confirmed that the government had “cut off Internet service (3G, DSL, Dial-up) all across the country, including government institutions,” according to ZDNet. Later, the site said Internet was available in some places, but “broken” in Damascus, Aleppo and “the provinces.” Syria’s Internet is controlled by the government-run Syrian Telecommunications Establishment, which provides core services to most ISPs, including DSL and dial-up. The shutdown seems to be in response to a call for mass “children” protests over the execution of 13-year-old Hamza al-Khatib. Thousands took to the streets anyway, and gunfire has been reported in multiple places; in Hama, security forces have reportedly killed at least 60. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | About two-thirds of Syria’s Internet networks became unreachable early this morning, security firm Renesys said on its website today. Within half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table, Renesys said. The country’s Web traffic depends on domestic operator Syriatel Mobile Telecom SA, the company said. To contact the editor responsible for this story: Simon Thiel at [email protected] ||||| Summary: Here we go again. This time Syria has cuts its people off from the Internet. What is with Arab dictatorships and their thinking that cutting their people off from the Internet is a good idea? First, it was Egypt. Then, it was Bahrain, and finally Libya gave it a try How's that working out for you guys? Egypt's government was overthrown; Bahrain's ruling family is hanging on thanks to outside support and mercenaries; and Libya's in the middle of a bloody civil war. All-in-all, trying to cut the people's communications' life lines just angers the protesters even more and draws the world's disapproving attention. The state-run Syria News site reported earlier today, June 3, 2011, that "The Syrian government has cut off Internet service (3G, DSL, Dial-up) all across the country (Arabic link), including government institutions." Later the same site reported that the Internet is available across parts of Syria [but that the] "Internet was 'broken' in Damascus, Syria's capital, and Aleppo, and the provinces." This sounds to me like the officials are making up their story on the fly. This, in turn, suggests that Syria's dictatorship hadn't really thought out the ramifications of turning off the Internet. As in the other Arab countries where the rulers tried the switching off the Internet gambit, Syria's Internet is controlled by the government. The Syrian Telecommunications Establishment (STE), which provides backbone services to other ISPs and DSL and dial-up services to businesses and individuals, is owned by the state. 3G and 3.5G wireless data services are available in larger cities from several providers. All of these, however, operate on the government's sufferance. In total, when the dictatorship allows it, about 17.7% of Syria's population has Internet access. The immediate cause for Syria's move appears to have been the call for mass "children" protests over the murder of a 13-year old boy, Hamza Ali al-Khateeb, in late April. In addition, Syrian strongman Bashar al-Assad continues to assault restive towns with the army. Regardless of tanks or the lack of the Internet though I strongly suspect that Syria's rebels are far from done and that al-Assad may yet find himself out of power.

– A strong odor alerted building manager Hasan Boztepe that something was not right inside John Littig and Lynne Rosen's Brooklyn apartment. When no one answered his repeated knocks, he broke down the door Monday and found the two radio hosts dead in a double suicide. They were sitting on a couch holding hands, the manager tells CNN, and they had each left a note behind. Littig's read: "I can't take it anymore, my wife is in too much pain." As for Rosen's, it "basically said she was sorry for doing this," a police source tells the New York Daily News. “We believe she had some psychological problems." The life coaches, whose show was described as focusing on "personal development, growth, and creativity," were in a common law marriage. They had been together 20 years, a neighbor tells the New York Post. "John was a very nice person. Lynne kept to herself," the neighbor says. "She was always putting on a lot of weight and taking it off." Other neighbors didn't have such kind words. One called Rosen "kind of a cold fish," and another told the Daily News Littig was fond of banging on his drums in frustration at all hours and would "fly into these crazy rages and scream like a crazed animal."

– Elon Musk apparently has no regrets about a tweet that set him and Tesla back each $20 million. In a tweet late Friday—just before tweeting that he would be taking a break from Twitter—Musk responded to a question about his ill-fated tweet claiming he would take the company private, which resulted in $40 million in SEC fines and him stepping down as company chairman, reports Reuters. "Worth It," he tweeted. Given that the ink is barely dry on the SEC fines, Gizmodo thinks that Musk's plan to take a break from "(firing) off word salad at all hours of the day and night" for a while "doesn’t seem like such a bad long-term plan." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | FILE PHOTO: Tesla Motors CEO Elon Musk speaks during the National Governors Association Summer Meeting in Providence, Rhode Island, U.S., July 15, 2017. REUTERS/Brian Snyder/File Photo (Reuters) - Tesla Inc (TSLA.O) Chief Executive Elon Musk said the tweet that cost him and the company $20 million in fines each by the U.S. Securities and Exchange Commision was “Worth It”. The tweet, sent late Friday evening less than an hour before Musk tweeted that he would take a break from Twitter “for a few days,” was in response to a question from a Twitter follower. The SEC in September charged Musk, 47, with misleading investors with tweets on Aug. 7 that said he was considering taking Tesla private at $420 a share and had secured funding. The tweets had no basis in fact, and the ensuing market chaos hurt investors, regulators claimed. Tesla Inc and Elon Musk have agreed to pay $20 million each to financial regulators and the billionaire will step down as the company’s chairman but remain as chief executive, under a settlement. Under the settlement agreement, Tesla needs to appoint an independent chairman by Nov. 13. ||||| Photo: Chris Carlson (AP) It’s arguably unfathomable that any human being slapped with a $20 million fine for a bad tweet would ever consider returning to the platform, much less continue to fire off word salad at all hours of the day and night. In the face of any logical explanation, however, one such man seemingly continues to insist that he is not owned. Tweeting Friday evening in a thread about “criticism” and “like” ratios on Twitter’s platform, Tesla CEO Elon Musk appeared to claim that his disastrous “420” tweet in August about taking the electric car company private was “worth” the tens of millions of dollars in fines regulators levied on him in response. Advertisement Why? The likes. Earlier this month, a judge officially approved Tesla’s settlement with the Securities and Exchange Commission after it argued that Musk made “false and misleading” statements in regards to going private. In the settlement, Musk and Tesla agreed to each pay a fine of $20 million, with Musk also forced to step down as Tesla’s chairman for at least three years. Tesla was also required to rein in Musk’s communications with investors. Advertisement This was a mere weeks ago. Remarkably, Musk later tweeted that he was going to sign “off Twitter for a few days,” which honestly doesn’t seem like such a bad long-term plan either.

– Well, this is embarrassing. Adam Kwasman, an Arizona state rep and Tea Party member who’s vying for a Republican congressional seat, joined an immigration-related protest Tuesday in the town of Oracle. He was there to protest against a local academy that plans on housing Central American immigrant children who’ve come unaccompanied across the border, but instead he got himself involved in a pretty significant mix-up, reports the Los Angeles Times. As a bus rolled up to the scene, Kwasman tweeted, “Bus coming in. This is not compassion. This is the abrogation of the rule of law.” (The tweet, which was accompanied by a photo of said bus, has since been deleted, but you can view a screen shot of it on Politwoops.) Except, er, the bus didn’t contain the immigrant children he thought it did. Kwasman also told 12 News KPNX that he could see “the fear” on the kids’ faces ... but the bus was filled with YMCA summer campers from a nearby school district, and according to one 12 News staffer who spotted them, they were actually laughing and taking pictures of the protest with their cellphones. When a 12 News reporter confronted Kwasman and said, “You know that was a bus with YMCA kids?” Kwasman replied, "They were sad, too," before ultimately apologizing. He continued his apology on Twitter later that afternoon, posting, “I apologize for the confusion. That was my error” and “Last tweet not the bus of illegal immigrant children. Thank God.” The Times notes that the Oracle protest was partly inspired by a July 1 protest in California that forced three buses of undocumented immigrants to turn around. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | A would-be congressman joined protesters in Oracle, Ariz., to object to housing some Central American immigrant children at a local academy. But when all was said and done, he might have been better off staying home. Protesters on both sides of the issue came to this town about 40 miles northeast of Tucson on Tuesday after Pinal County Sheriff Paul Babeu warned that Sycamore Canyon Academy would be sheltering some unaccompanied minors who have crossed the Southwestern border illegally. About 57,000 such children have been apprehended at the border since October. The young immigrants typically are held for a short time at the border, then transferred to the Department of Heath and Human Services, and often released to relatives with notices to appear in court later. Under a 2008 law, children from all nations but Mexico and Canada have the right to an immigration hearing. Oracle's Sycamore Canyon Academy confirmed that it had a contract to house a "small number" of the children, the Associated Press reported. Protesters gathered early and waited for buses to arrive -- inspired at least in part by a July 1 demonstration in Murrieta, Calif., that forced three buses of immigrants to turn back. Then Adam Kwasman, a state representative and tea party member who is seeking the Republican nomination for Arizona's 1st Congressional District, tweeted from the scene: "Bus coming in. This is not compassion. This is the abrogation of the rule of law." Kwasman, demonstrators and camera crews converged on a yellow school bus filled with children, according to video. Later, Kwasman told KPNX-TV Channel 12 in Phoenix, "I was able to actually see some of the children on the buses, and the fear on their faces. This is not compassion." Reporter Brahm Resnik responded, "You know that was a bus with YMCA kids?" "They were sad too," Kwasman retorted. Resnik said the children actually were smiling and taking cellphone photos. They were YMCA campers from the Marana Unified School District, he said. Kwasman backed off, apologized and removed his earlier tweets. But they can be found at Politwoops, which bills itself as "an archive of the public statements deleted by U.S. politicians. Explore the tweets they would prefer you couldn't see." On Tuesday night, Kwasman's campaign website and Twitter account included these tweets: "Last tweet not the bus of illegal immigrant children. Thank God." "I apologize for the confusion. That was my error." At last report, no buses with migrant children had arrived in Oracle. @conniestewartLA ||||| An archive of the public statements deleted by U.S. politicians.

– If you were watching ABC's election coverage last night, there was probably just one question on your mind: Is Diane Sawyer really drunk, or just tired? Gawker has an amusing video montage that seems to support what many assumed: She was smashed. The video pieces together clips of Sawyer slurring and stumbling over her words, swaying in her seat, vehemently complaining about the lack of music, rambling about the exclamation point in Obama's campaign slogan, and at one point intensely reminding viewers that people have "died—literally died" for the right to vote. All the while, George Stephanopoulos looks on with, at times, apparent frustration at his inability to get a word in. The Atlantic Wire rounds up some of the better tweets about the situation ("And Diane Sawyer declares tonight's winner is … chardonnay!"), and has yet more video evidence that we've seen Sawyer like this in the past. But its conclusion is that Sawyer simply gets weird when she's tired. Meanwhile, another news anchor also made headlines last night: On NBC, Brian Williams totally "crushed" Donald Trump, Business Insider reports. Williams reluctantly reported on Trump's Twitter feed, noting that Trump had "driven well past the last exit to relevance and veered into something closer to irresponsible" with his angry election-related tweets. Williams then read some of the tweets on air, before ending with, "So, that happened." Click for a third buzzed-about media moment of the night. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | As the election has drawn closer, Donald Trump's voice on Twitter has gotten louder. And progressively more insane. Finally, he's getting called for his nonsense. On NBC, Brian Williams said, Trump has "driven well past the last exit to relevance and veered into something closer to irresponsible." Williams also read some of Trump's dopey tweets on the air, then said, "So, that happened." It is an extra interesting comment from Williams because Trump is a star for NBC with "The Apprentice." It's rare for two big network personalities to clash. But, the truth of the matter is that Trump has been a clown for this entire election cycle. Someone had to point it out. ||||| [There was a video here] Diane Sawyer was definitely probably drunk tonight during ABC's election coverage. Would you agree? Not convinced yet? She slurred every other word, rambled about the lack of music, and asked a correspondent if the exclamation point in the Obama slogan represented the direction he truly wanted to go with his presidency. What more proof do you need? But of course it was already true according to Twitter: nothig to c here guys im ok d'ont worry abot me — Drunk Diane Sawyer (@DrnkDianeSawyer) November 7, 2012 And from our own Caity Weaver: "IT'S LIKE SHE TOOK AN AMBIEN AND WASHED IT DOWN WITH PINOT." Wouldn't be the first time. ||||| Once again, Diane Sawyer helped to lead ABC's Election Night coverage, and once again, she appeared entirely intoxicated while doing so. At least, that's what Twitter thought. As the last of the polls closed on Tuesday night, "Diane Sawyer" became a trending topic and not in a good way. John Gruber who runs the blog Daring Fireball tweeted, "Swear to god, Diane Sawyer is drunker than I am." The popular 90s band They Might Be Giants chimed in, "And Diane Sawyer declares tonight's winner is... chardonnay!" New York Times media report Brian Stelter cut Sawyer some slack, "Diane Sawyer's name is trending. Many people saying she seems drunk on air. Alternative theory: she gets this way when she's really tired." Stelter's on to something. We've seen Diane Sawyer in this state before. The night after Barack Obama's inauguration in 2009, Sawyer appeared pretty cheerful on Good Morning America. She also had a hard time putting sentences together which led many to draw the conclusion that she was still drunk from the night before. Then, like now, we're not sure the slurred words and excessive smiles are necessarily proof that Sawyer had done some drinking, but she does look a little bit out of character. Oh well. We all do weird things when we're tired. Want to add to this story? Let us know in comments. You can share ideas for stories on the Open Wire. Adam Clark Estes |

the problem of dynamical generation of 4-d space - time signature at small scales and its stabilization towards lorentzian signature at large scales is studied in the context of higgs mechanism in a two - time scenario .
it is also shown that lorentz invariance at small scales can be violated but at large space - time scales is restored .
-0.75 in the initial idea of signature change was due to hartle , hawking and sakharov @xcite .
this idea would make it possible to have both euclidean and lorentzian metrics in the path integral approach to quantum gravity .
however , it was later shown that signature change may happen , as well , in classical general relativity @xcite .
this issue has recently been raised in the brane - world scenario , as well @xcite .
there are two different approaches to this problem : continuous and discontinuous . in the continuous approach , in passing from euclidean to lorentzian region , the signature of the metric changes continuously , hence the metric becomes degenerate at the border . in the discontinuous approach , however , the metric is non - degenerate everywhere and discontinuous at the border .
most of the works regarding the signature change dealt with situations where the signature changing metric is defined _ apriori _ on the manifold and one looks for the effects of the assumed signature change on the einstein equations or propagation of particles in such a manifold .
however , there are some other viewpoints in which the signature generation of the large scale space - time is studied and considered to be a dynamical phenomenon @xcite , @xcite , @xcite . on the other hand , it is believed that while the signature of the large scale 4-d space - time is definitely lorentzian , the phenomena of dynamical topology and signature changes at ultrashort distances can happen as the microscopic fluctuations of the space - time .
this is because a more general formulation of gravitation should accommodate geometries with degenerate metrics and nontrivial topologies .
it is then interesting to introduce one mechanism which accommodates both small and large scales and addresses the problem of metric signature at these hierarchial scales . in the present letter
, we propose such a mechanism for signature fluctuations at ultrashort distances and stabilization of lorentzian signature at large scale 4-d space - time , in the context of higgs mechanism in a two - time scenario .
we introduce a higgs potential whose minima will define the signature of the 4-d metric .
the parameter of the symmetry breaking is so chosen that it leads to a quantum oscillating signature at ultrashort distance and a definite signature at large scale .
it is then discussed that the lorentzian signature of the present large scale universe might have been generated due to a quantum tunneling effect at very early universe and that the immediate inflation could have stabilized this chosen lorentzian metric and prevented this new baby universe from re - tunneling to an euclidean phase .
the subsequent big bang and the observed acceleration of the universe are then considered as different ways by which the universe could have fixed the lorentzian metric as the preferred one . beside this scenario
, it is also shown that at the present large scale lorentzian universe there can be fluctuating signature at small scales which may be accompanied by a constant time - like vector that accounts for a principle violation of the lorentz invariance at small scales . at large scales , although a same vector can in principle exist but its norm is vanishing and so is non - observable .
this leaves the lorentz invariance as an almost exact symmetry at large space - time scales .
consider the 5-d two - time metric
@xmath0 where @xmath1 accounts for 3-space metric , @xmath2 is the extra time dimension , and @xmath3 is assumed to be the vacuum expectation value of a dimensionless higgs field with the following potential @xcite @xmath4 where @xmath5 and @xmath6 together with @xmath7 are the parameters of the potential .
it is assumed that the 4-dimensional metric is independent of the extra time , but the higgs field depends merely on @xmath2 .
the choice of @xmath7 is of particular importance in incorporating the notions of large and small scales in the study of signature dynamics .
in fact , no absolute line of demarcation can exist between small and large scales without having a positive definite measure of distance .
therefore , we assume a characteristic size in the ultrashort distance regime , described by an absolute scale of length @xmath8 , which acts as a sort of universal length that determines a lower bound on any scale of length probed in a measurement process . the existence of universal length @xmath8 is not compatible with the universal requirement of lorentz invariance .
such a violation of lorentz invariance may be a consequence of unification of quantum physics and gravity and is expected to manifest itself at ultrashort distances .
we therefore take @xmath9 where @xmath10 is the characteristic size of the region over which one measures the signature of metric . by starting from a very large parameter @xmath11 , namely @xmath12
, one finds that the potential has one minimum at @xmath13 as is shown in fig.1 .
however , at some ( critical ) smaller parameter @xmath14 ( @xmath15 is presumably the planck length @xmath16 ) , the potential will have three minima at points where @xmath17 ( see fig.2 ) .
one of these minima is at @xmath13 and two others are at @xmath18 .
in other words , at @xmath19 there are two phases in equilibrium with each other , one with @xmath13 and the other with @xmath20 ( or @xmath21 ) .
the phase with @xmath13 is stable when @xmath22 , and _ meta - stable _ when @xmath10 is a bit larger than @xmath15 .
the order parameter , namely @xmath3 , is discontinuous at the transition @xmath19 .
therefore , we are dealing with a _ first order phase transition _ where two phases can coexist , one with @xmath13 and the other with nonzero @xmath3 .
one may then find meta - stability so that the system can persist in the phase with @xmath13 , for the parameter @xmath10 very close to @xmath15 .
when @xmath23 , the potential @xmath24 is unstable at @xmath13 , but has two negative minima which are stable , as fig.3 .
in such case , there can never be coexistent phases at @xmath13 and @xmath25 .
therefore , the unstable phase at @xmath13 is removed and a stable phase should be chosen out of two minima at @xmath26 .
this means , when @xmath27 we have the degenerate 4-d metric @xmath28 everywhere on the manifold , before symmetry breaking .
then , at some smaller parameter @xmath7 namely @xmath14 the 4-d metric is capable of taking on the following forms @xmath29 corresponding to three equal minima of the potential where @xmath17 , so that they can be in equilibrium with each other .
the manifold at the scale @xmath15 is then capable of being degenerate , euclidean , and lorentzian . in other words , the signature of metric oscillates ( in @xmath2 ) between the above three forms due to quantum tunneling between the minima of the potential .
if the parameter @xmath10 begins to increase above @xmath15 the system will provisionally be meta - stable so that the metric can persist , for the parameter @xmath10 close to @xmath15 , in coexistent phases .
finally , at @xmath23 the system is unstable at @xmath13 and has two negative minima .
this means , the manifold can no longer have a degenerate metric and the signature can just oscillate between euclidean and lorentzian , due to quantum tunneling between the two minima . as @xmath10 increases above @xmath8 the system becomes more stable so that for @xmath30 the tunneling probability approaches zero and the preferred signature is permanently fixed .
a few words on the length scales @xmath8 and @xmath10 are in order . in one hand ,
the existence of a universal length @xmath8 in the small scale regime is in sharp contrast with the universal requirement of lorentz invariance . on the other hand , one can not distinguish between large and small scales without having a positive definite metric . according to blokhintsev @xcite ,
accompanying the notion of a universal length ( lorentz non - invariance ) with a constant time - like vector @xmath31 , it is possible to distinguish between small and large scales in minkowski space - time by taking the positive definite interval @xmath32 therefore , the existence of a universal length @xmath8 at ultrashort distance regime is inevitably related to the existence of an _ internal _ time - like vector @xmath33 over the manifold . given the euclidean metric @xmath34 one may determine the absolute size of a distance by comparing @xmath35 with the universal length @xmath8 . in the same way , one may determine the absolute size of the distance @xmath10 and determine the meaningful value of the parameter @xmath7 . with no loss of generality one
may take the distance @xmath10 to be the radius of universe , namely the scale factor @xmath36 .
therefore , one may expect different phases in the potential according to the evolution of @xmath36 . at very early universe @xmath37 ( or @xmath38 )
we have not a meaningful notion of the metric because it is degenerate . at @xmath39
, the metric can fluctuate between euclidean , degenerate and lorentzian forms .
this is plausible in the quantum gravity regime @xmath40 and is consistent with quantum tunneling in cosmology in which the universe tunnels from nothing ( @xmath41 ) , through a euclidean region , to the planck length @xmath16 at which the universe may fluctuate between euclidean ( @xmath42 ) , degenerate ( @xmath43 ) and lorentzian ( @xmath44 ) forms .
as long as the scale factor is close to the planck length these quantum oscillations ( in @xmath2 ) persist with no preference for euclidean or lorentzian metric to be the permanent one .
this means the true vacuum of the potential is not yet selected .
however , once some suitable initial conditions are provided for one of the quantum tunnelings to the lorentzian region , the universe can start time ( @xmath45 ) evolution in the scale factor towards @xmath8 and this stabilizes the lorentzian metric because @xmath7 decreases . therefore , at the scale @xmath46 the metric is definitely lorentzian which means @xmath47 is selected as the preferred minimum of the potential .
however , the probability for quantum tunneling to the euclidean region is not yet excluded , because the barrier between the two minima is not so high and wide .
the new born lorentzian universe can get rid of death ( thorough quantum re - tunneling to the euclidean region ) by undergoing an inflation in the scale factor .
this inflation launches the small scale factor @xmath48 ( presumably the grand unification scale ) to a distance tens of order greater than @xmath8 in a very short period of time , namely @xmath49 seconds .
hence @xmath7 becomes very small and leads to a very high barrier so that the probability for quantum tunneling becomes very small , as well . in this regard
, the inflation helps the lorentzian metric to be stabilized in a tiny fraction of a second .
after inflation , the big bang also causes the universe to be expanded rapidly which leads to more stabilization of the lorentzian metric .
this stabilization is continued as long as the universe expands .
one may then interpret the expansion of the universe as a way to avoid re - tunneling to the euclidaen metric .
the recent observed acceleration of the universe may also be addressed and justified according to this scenario .
now suppose there is a constant internal vector on the 4-d manifold as @xmath50 associated with the properties of vacuum through @xmath3 .
then , for @xmath51 we have @xmath52 corresponding to the absolute minimum at @xmath13 , before symmetry breaking .
when @xmath53 , the parameter @xmath7 decreases and the vector @xmath33 is found in a non - vanishing form , namely @xmath54 .
this means that before symmetry breaking , when @xmath55 , there is no @xmath33 at all , and one is appeared at the symmetry breaking at @xmath53 . at
@xmath56 where only euclidean and lorentzian metrics are available through the quantum tunneling , one may use this non - vanishing @xmath33 to relate the euclidean metric @xmath57 and lorentzian one @xmath58 @xmath59 with no restriction on the norm of @xmath33 .
this is because the permanent metric is not fixed .
however , far from the critical point , @xmath60 where the true vacuum of the system is singled out as the lorentzian metric @xmath58 , we find , by contracting eq.([4 ] ) with @xmath61 , that the internal vector has negative norm @xmath62 which accounts for the time - like nature of @xmath33 , as is required according to blokhintsev point of view .
notice that the norm of @xmath33 is almost vanishing for @xmath63 , namely @xmath64 , and becomes important at small scales @xmath65 .
therefore , the internal vector @xmath33 is non - observable at large scales which means the lorentz invariance is an almost exact symmetry at large distances compared with @xmath8 . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | we have discussed that as long as suitable initial conditions for time evolution of the scale factor were not satisfied at very early universe the 4-d metric could have been oscillating quantum mechanically between euclidean and lorentzian phases as degenerate vacuums of a higgs potential . however , once these conditions were satisfied in one of the tunnelings into a lorentzian vacuum ( early universe ) , the immediate inflation and the subsequent big bang could have stabilized this chosen metric . in this regard , inflation , big bang and even the present observed acceleration of the universe can be considered as different behaviors of the universe to escape the death through re - tunneling to the euclidean metric .we have also shown that lorentz invariance at small scales can be violated but at large space - time scales it can be restored exactly .this work has been supported financially by the research department of azarbaijan university of tarbiat moallem , tabriz , iran .+ 99 j. b. hartle , s. w. hawking , phys .rev . d.*28 * ( 1983 ) , 2960 .t. dereli , r. w. tucker , class .quantum grav.*10 * ( 1993 ) , 365 ; g. f. r. ellis , a. sumruk , d. coule and c. hellaby , class .quantum grav.*9 * ( 1992 ) , 1535 ; s. a. hayward , class .quantum grav.*9 * ( 1992 ) , 1851 ; m. kossowski , m. kriele proc .lond . a.*446 * ( 1995 ) , 115 ; c. hellaby , t. dray , phys .d. * 49 * ( 1994 ) , 5096 ; f. darabi , h. r. sepangi , class .quantum grav.*16 * ( 1999 ) , 1565 ; f. darabi , phys . lett . a*259 * ( 1999 ) , 97 ; m. mohseni , phys . lett . a*267 * ( 2000 ) , 240 .m. mars , j. m. m. senovilla , r. vera , phys .lett.*86 * ( 2001 ) , 4219 ; g. w. gibbons , a. ishibashi , _ topology and signature changes in braneworlds _ , hep - th/0402024 .r. precacci , nucl .phys . b*353 * ( 1991 ) , 271 .j. greensite , phys .lett . b*300 * ( 1993 ) , 34 ; a. carlini , j. greensite , phy .rev . d*49 * ( 1994 ) , 866 .s. d. odintsov , a. romeo and r. tucker , class .quantum grav.*11 * ( 1994 ) , 2951 ; e. elizalde , s. d. odintsov and a. romeo , class .quantum grav.*11 * ( 1994 ) , l61 .p. wesson , phys .b*538 * ( 2002 ) , 159. m. le bellac , _ quantum and statistical field theory _ , ( clarendon press , oxford ) ( 1991 ) .d. i. blokhintsev , physics letters * 12 * ( 1964 ) , 272 . |

– A candidate running for the Texas state legislature is garnering attention over her campaign donations—most of which consist of frozen deer semen, the Hill reports. Ana Lisa Garza has received $87,500 for her gutsy run against eight-term Democrat Ryan Guillen, $51,000 of which are listed as in-kind donations of deer semen straws. "Semen is a very common way for us to donate," says Texas deer breeder Fred Gonzalez. "One collection on a buck could lead to 60 straws sometimes. If you have a desirable animal, it’s a way to bring value without breaking the bank." The straws, or containers of ejaculate, are each valued at $1,000 by the Garza campaign. Oddly, the campaign lists them as "in-kind" donations even though they were sold at auction and donated as cash, but Austin-based attorney Buck Wood doesn't see an issue. "The only time in-kind is important when you can’t estimate the value of the in-kind contribution," he says. Between 2006 and 2016 the Texas Deer Association's PAC has actually gotten more than $976,000 in donations of deer semen, and always made donations as money, not semen, the Dallas Morning News reports. So why give to Garza? Gonzalez says she gets deer breeders. "Some people don’t like deer breeders," he adds. "Some people don’t understand the benefit that we provide to Texas and small landowners." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | AUSTIN — Donations of deer semen, one of Texas deer breeders’ most precious commodities, account for more than half of the contributions to a South Texan’s state House campaign. Ana Lisa Garza, a Starr County district court judge, is challenging Rio Grande City Democrat Ryan Guillen for the District 31 seat he’s held for eight terms. According to her last campaign finance report, Garza received $36,500 in monetary donations and $51,000 in in-kind donations, which are usually in the form of campaign advertising, polls or food and venue space for events. In Garza’s case, the contributions were listed as individual donations of deer semen straws from deer breeders. ||||| A candidate in the race for a South Texas state House seat has reportedly received $87,500 in campaign donations — more than half of which is made up of deer semen. The Dallas News reported Thursday that Ana Lisa Garza, a district court judge running a primary challenge against eight-term Democrat Ryan Guillen, has received $51,000 in in-kind donations to her campaign, listed as individual donations of frozen deer semen straws. The containers are reportedly a common way for deer breeders in the state to donate to political campaigns. Garza's campaign has valued the straws at $1,000 each. Fred Gonzalez, a Texas deer breeder who serves as treasurer of the Texas Deer Association, told the Dallas News that the group’s political action committee has received more than $975,000 in deer semen donations since 2006, and has given more than $885,000 in the same period of time. ADVERTISEMENT “Semen is a very common way for us to donate,” Gonzalez told the paper. “One collection on a buck could lead to 60 straws sometimes. If you have a desirable animal, it’s a way to bring value without breaking the bank.” Straws from bucks named Bandit, Sweet Dreams and Gladiator Sunset were among the donations listed. The group does not give the semen directly to the campaign, but accepts the straw donations and sells them at auction. In the case of Garza’s campaign, Gonzalez said the straw donations were sold as one lot. Garza’s campaign finance forms list the donations from the individual breeders, according to the paper. Buck Wood, a campaign finance and ethics attorney, told the Dallas News that the donations technically were not “in-kind” since the money, not the semen, was given to the campaign, but that it does not raise any ethical or legal concerns. “If they’d given her the straws, that would have been an in-kind donation,” he said. In-kind donations usually cover things like campaign advertising or event space. Guillen, the lawmaker Garza is running to unseat, ran unopposed in the last two elections and received 100 percent of both the primary and general election vote, making the March 6 primary a tough challenge for Garza. |

– Police in a Dallas suburb say they've found the body of a small child not far from the home of a 3-year-old girl who's been missing since earlier this month. Richardson police say the child's body was discovered in a culvert as authorities using dogs searched for Sherin Mathews on Sunday morning. The Dallas News reports the location is less than a mile from her home. Her father, Wesley Mathews, has told authorities he ordered the child to stand next to a tree behind the fence at their home around 3am on Oct. 7 as punishment for not drinking her milk and she went missing. Police say the body hasn't been positively identified but that they have no reason to believe it's a different child. No details have been released on how the child died. The AP reports Mathews, who went outside to check on the girl around 3:15am, is charged with child endangerment. After not finding her, he decided to wait until daylight to look again and did laundry while waiting. The girl's mother was asleep throughout the incident. Police say the family's Acura SUV was away from the home during the 4am hour on the morning Sherin went missing. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | FILE- This undated photo provided by the Richardson Texas Police Department shows 3-year-old Sherin Mathews.

(Associated Press) RICHARDSON, Texas (AP) — Police in a Dallas suburb say they've found the body of a small child not far from the home of a 3-year-old girl who's been missing since earlier this month. Richardson police say the child's body was discovered in a culvert as authorities using dogs searched for Sherin Mathews on Sunday morning. Her father, Wesley Mathews, has told authorities he ordered the child to stand next to a tree behind the fence at their home around 3 a.m. on Oct. 7 as punishment for not drinking her milk and she went missing. He is charged with child endangerment. Police say the body hasn't been positively identified but that they have no reason to believe it's a different child. No details have been released on how the child died. ||||| Updated at 10 a.m. Monday: Revised to report that another daughter will remain in CPS custody for now. Less than a mile from the Richardson home where a missing 3-year-old was last seen two weeks ago, officials on Sunday discovered the body of a young child. Police have not yet confirmed whether the body is that of Sherin Mathews, who has been missing since Oct. 7, but they indicated they have no reason to think it is a different child. The medical examiner will determine the child’s identification and cause of death. "The indications are that it is most likely her, however, we have not had positive ID. So until we have a positive identification we are not going to say it is Sherin," Sgt. Kevin Perlich said. The body was found about 11 a.m. in a culvert near East Spring Valley and South Bowser roads, east of U.S. Highway 75, with the help of search dogs. |

applying the local density approximation ( lda ) and dynamical mean field theory ( dmft ) to paramagnetic @xmath0iron , we revisit a problem of theoretical description of its magnetic properties .
the analysis of local magnetic susceptibility shows that at sufficiently low temperatures @xmath1 k , both , @xmath2 and @xmath3 states equally contribute to the formation of the effective magnetic moment with spin @xmath4 .
the self - energy of @xmath3 states shows sizable deviations from fermi - liquid form , which accompanies earlier found non - quasiparticle form of @xmath2 states . by considering the non - uniform magnetic susceptibility
we find that the non - quasiparticle form of @xmath2 states is crucial for obtaining ferromagnetic instability in @xmath0-iron .
the main contribution to the exchange interaction , renormalized by the effects of electron interaction , comes from the hybridization between @xmath3 and @xmath2 states .
we furthermore suggest the effective spin - fermion model for @xmath0-iron , which allows us to estimate the exchange interaction from paramagnetic phase , which is in agreement with previous calculations in the ordered state within the lda approaches .
elemental iron in its low - temperature body - centered cubic ( bcc ) phase , which is stable below approximately 1200 k , provides unique example of itinerant magnetic @xmath5-electron systems , where formation of well - defined local magnetic moments can be expected .
indeed , the rhodes - wolfarth ratio @xmath6 for this substance is very close to one , which is characteristic feature of systems , containing ( almost ) localized @xmath5electrons ( @xmath7 corresponds to the magnetic moment , extracted from the curie
weiss law for magnetic susceptibility in the paramagnetic phase @xmath8 , and @xmath9 is the saturation moment , @xmath10 is a lande factor , @xmath11 denotes temperature ) . at the same time , the moment @xmath12 has a small fractional part , which is natural for the itinerant material .
this poses natural questions : which electrons mainly contribute to the local - moment spin degrees of freedom of @xmath0-iron ?
what is the appropriate physical model , that describes spin degrees of this substance ? attempting to answer the former question , goodenough suggestedgoodenough , that the @xmath2 electrons are localized , while @xmath3 electrons are itinerant .
this suggestion was later on refined in ref .
, pointing to a possibility , that only some fraction of @xmath2 electrons , contributing to formation of the peak of the density of states near the fermi level , named by the authors as giant van hove singularity , is localized .
( the intimate relation between peaks of density of states and electron localization was also previously pointed out in ref . ) . on contrary , there were statements made that @xmath13 of electrons are localized in iron@xcite .
on the model side , the thermodynamic properties of @xmath0-iron were described within the effective spin @xmath4 heisenberg model @xcite , assuming therefore that the main part of magnetic moment is localized , in agreement with the above - mentioned rhodes - wolfarth arguments .
use of the effective heisenberg model was justified from the ab
initio analysis of spin spiral energies yielding reasonable values of the exchange integrals @xcite .
these considerations however did not take into account strong electronic correlations in @xmath0iron , which important role was emphasized first in ref . .
previous calculations katanin2010,abrikosov2013 within the local density approximation ( lda ) , combined with the dynamical mean - field theory ( dmft ) revealed the presence of non - quasiparticle states formed by @xmath2 electrons , which were considered as a main source of local moment formation in iron , while @xmath3 states were assumed to be itinerant@xcite . at the same time
, magnetic properties of the same @xmath3 states also show some features of local - moment behavior . in particular
, the temperature dependence of inverse local spin susceptibility , which was calculated previously@xcite only at @xmath14 k because of the limitations of hirsch - fye method , is approximately linear , including the contribution of @xmath3 states ; the real part of @xmath3 contribution to dynamic local magnetic susceptibility has a peak at low frequencies , reflecting a possibility of partial local moment formation by @xmath3 states . studying this possibility requires investigation of electronic and magnetic properties at low temperatures , since the energy scale for partially formed local @xmath3 moments can be smaller than for @xmath2 states . although real substance orders ferromagnetically at low temperatures , in the present paper ( as in ref . )
we perform analysis of local properties of iron in the paramagnetic phase to reveal the mechanism of local moment formation . furthermore , we study non - local magnetic susceptibility in the low temperature range @xmath15 @xmath16 which allows us to analyze the mechanism of magnetic exchange . to this end
we use the state of art dynamical mean field theory ( dmft ) calculation with continous time quantum monte - carlo ( ct qmc ) solver@xcite , combined with the ab - initio local density approximation ( lda ) . from our low - temperature analysis
we argue , that @xmath3 electrons are almost equally contribute to the effective local magnetic moment , as the @xmath2 electrons , and play crucial role in the mechanism of magnetic exchange in iron .
in particular , the most important contribution to the exchange integrals comes from the hybridization of @xmath3 and @xmath2 states , which yields _ nearest - neighbour _ magnetic exchange interaction , which agrees well with the experimental data .
we perform the ab initio band structure calculations in lda approximation within tight binding linear muffin tin orbital atomic spheres approximation framework ; the von barth - hedin local exchange - correlation potential @xcite was used .
primitive reciprocal translation vectors were discretized into 12 points along each direction which leads to 72 * k*points in irreducible part of the brillouin zone . for dmft ( ct - qmc ) calculations ,
we use the hamiltonian of hubbard type with the kinetic term containing all @xmath17@xmath18@xmath5 states , being extracted from the lda solution , and the interaction part with density - density contributions for @xmath5 electrons only .
the coulomb interaction parameter value @xmath19 ev and the hund s parameter @xmath20 ev used in our work are the same as in earlier lda+dmft calculations lichtenstein_2001,katanin2010,igoshev2013 . to treat a problem of formation of local moments we consider paramagnetic phase , which is achieved by assuming spin - independent density of states , local self - energy and bath green function . for the purpose of extracting corresponding exchange parameters , we take in lda part physical value of the lattice parameter @xmath21 , corresponding to ferromagnetic state at room temperature .
we consider first the results for the orbital resolved temperature dependent local static spin susceptibility @xmath22 , where @xmath23 is the @xmath24projection of the spin of @xmath5electrons , belonging to the orbitals @xmath25 at a given lattice site @xmath26 , see fig .
[ fig : inverse_chi ] ( for completeness , we also show the total susceptibility @xmath27 which also includes the off - diagonal @xmath3-@xmath2 contribution ) . the temperature dependence of the static inverse local susceptibility is linear ( as was also observed in previous studies lichtenstein_2001,katanin2010,abrikosov2013,igoshev2013 ) , however being resolved with respect to orbital contributions ( see fig .
fig : inverse_chi ) it appears to manifest very different nature of @xmath2 and @xmath3 moments .
the inverse @xmath2 orbital contribution behaves approximately linearly with @xmath11 in a broad temperature rangekatanin2010,abrikosov2013 . at the same time , analyzing low - temperature behaviour , we find that @xmath28 demonstrates a crossover at @xmath29 k between two linear dependences with the low temperature part having higher slope ( i. e. smaller effective moment ) .
note that this feature was not obtained in previous study @xcite because of considering only temperature range @xmath14 k. the scale @xmath30 corresponds to the crossover to non - fermi - liquid behavior of @xmath3 states , see below . and @xmath3 orbital contributions .
dashed lines show linear behavior in different temperature intervals .
, scaledwidth=47.0% ] and @xmath31 in @xmath32iron , extracted from the temperature dependence of local susceptibility , together with the contribution of the @xmath2 and @xmath3 orbitals , scaledwidth=47.0% ] to get further insight into the local magnetic properties of @xmath0-iron , we consider the temperature dependence of the effective magnetic moment @xmath33 and the instantaneous average @xmath34 corresponding to different orbital states , see fig .
[ fig : moms_vs_t ] .
we find , that for @xmath2 electrons both moments saturate at temperatures @xmath1 k and remain approximately constant up to sufficiently low temperatures . comparing the value of the square of the moment @xmath35 , extracted from the curie - weiss law for local susceptibility , and the instantaneous average @xmath36 with the corresponding filling @xmath37 , we find that the major part of @xmath2 electrons determine the instantaneous average @xmath38 , and at least half of them contribute to the sufficiently long - living ( on the scale of @xmath39 ) local moments . at the same time , for @xmath3 electronic states the abovementioned crossover between the high - temperature value @xmath40 and the low temperature value @xmath41 is present , which , comparing to @xmath42 shows that at least @xmath43 of @xmath3 electrons participate in the effective local moment formation at low temperatures . yet , the corresponding low - temperature effective moments @xmath44 and @xmath45 are comparable ( each of them is approximately @xmath46 corresponding to the effective spin @xmath47 ) , showing important role of @xmath3 electrons in the formation of the total spin @xmath4 state . .
black solid lines illustrate the results of calculations at temperatures ( from top to bottom ) @xmath48 ev .
the green dot dashed line present fits to the the fermi - liquid dependence in the range @xmath49 ev , while blue dashed lines present fits to the non - fermi - liquid dependence ( see text ) .
dots denote matsubara frequencies @xmath50.,scaledwidth=44.0% ] although the self - energy calculations @xcite yield quasiparticle - like form of @xmath3 electron self - energy , the low - frequency and low - temperature dependence of self - energy shows pronounced deviations from the fermi - liquid behavior , see fig . [ fig : sigma ] . to analyse the frequency dependence of the self - energy on imaginary frequency axis , we fit the obtained results by the fermi - liquid dependence @xmath51\nu + \sigma ( t)\nu ^{2},$ ] where @xmath52 is the damping of electrons at the fermi level , @xmath53 is the temperature - dependent quasiparticle residue . alternatively , we consider the fit @xmath54 with some exponent @xmath55 .
the latter dependence corresponds to the non - fermi - liquid behavior of @xmath3 electrons .
the obtained results are presented in the table .
@xmath56 the linear - quadratic fits are applicable only at @xmath57 ev ; at sufficiently small @xmath58 they also do not fit the obtained results well .
we find that the spectral weight @xmath53 pronouncely decreases with decrease of temperature , and the coeffitient @xmath52 obviously does not obey the fermi - liquid dependence @xmath59 .
these observations show that sizable deviations from fermi - liquid picture can be expected .
the power - law fits yield much better agreement in a broad range of frequencies @xmath60 ev , describing at the same time correctly the low - frequency behavior .
the coefficients @xmath61 @xmath62 of these fits show very weak temperature dependence ( the contribution @xmath63 is almost negligible ) , while the damping @xmath64 and the exponent @xmath0 slightly decrease with temperature , being related by @xmath65 .
these observations imply that @xmath3 electronic subsystem is better described by non - fermi liquid behavior at low temperatures , which reflects its participation in the formation of local moments in @xmath0-iron .
remarkably , consideration of the three - band model in ref
. showed similar dependence of the self - energy @xmath66 due to hund exchange interaction , which allows to attribute the @xmath3 subsystem in iron as close to the " spin freesing transition , accroding to the terminology of ref . .
to get further insight into the formation of effective local moments and extract corresponding exchange integrals , we calculate the momentum dependence of particle - hole bubble @xmath67 , which is obtained using paramagnetic lda and lda+dmft electronic spectrum [ @xmath68 is the corresponding electronic green function for the transition from the orbital state @xmath69 to @xmath70 , @xmath71 is a fermionic matsubara frequency ; for more details on the calculation procedure see ref . ] . at @xmath72 k calculated in high symmetry directions of the brillouin zone .
the contributions @xmath73 , @xmath74 , @xmath75 , and the hybridization part @xmath76 are shown by black , red , green and blue lines , respectively .
solid ( dashed ) lines correspond to lda+dmft ( lda ) results .
the lda+dmft estimate for @xmath77 is shown by magenta short dashed line .
, scaledwidth=44.0% ] the results for lda and lda+dmft approaches at @xmath72 k are presented in the fig .
[ fig : chi : lda_vs_dmft ] ( we find that the lda+dmft results are almost temperature - independent at low @xmath11 ) . for the bubble , calculated using purely lda spectrum ( i.e. with the assumption that all electrons are itinerant ) , the maximum of @xmath78 is located at the point @xmath79 , while the ferromagnetic instability in @xmath0-iron requires maximum of @xmath78 at @xmath80 and low @xmath81 if one neglects the non - local vertex corrections .
one can observe , that the main contribution to this incorrect behavior of the bubble originates from the @xmath2 electron part , @xmath82 .
both @xmath82 and @xmath83 contributions are however strongly influenced by the account of the local self energy corrections to the green s function in dmft approach , which correspond physically to account of partial localization of @xmath5-electrons .
these corrections mainly change @xmath84 and shift the maximum of @xmath85 to @xmath86 point ( @xmath80 ) .
note that within lda+dmft , intra
orbital contributions to @xmath82 and @xmath87 are only weakly momentum - dependent ; they also behave similarly , varying counter phase . according to the general ideas of spin - fluctuation theory @xcite
, this weak momentum dependence can be ascribed to the formation of the effective moments from @xmath2 and @xmath3 states . in agreement with the abovediscussed consideration
, the @xmath84 contribution has even weaker dispersion than the @xmath88 part . at the same time ,
strongly dispersive @xmath89 contribution , which is assumed to correspond to the ( remaining ) itinerant degrees of freedom , provides the maximum of the resulting @xmath78 at @xmath80 and appears to be the main source of the stability of the ferromagnetic ordering in iron within lda+dmft approximation .
the obtained results do not change qualitatively for the other choice hubbard interactions ( as we have verified for @xmath90 and @xmath91 ev ) , see supplementary material @xcite . to see the quantitative implications of the described physical picture
, we consider the effective spin - fermion model @xmath92 c_{l^{\prime } \sigma } ( \mathrm{i}\nu _ { n } ) \notag\end{aligned}\]](@xmath93 is a bosonic matsubara frequency , @xmath94 combines site and orbital indices ) , describing interaction of itinerant electrons with ( almost ) _ local _ spin fluctuations ( in contrast to critical spin fluctuation in cuprates @xcite ) , see also ref .
@xcite .
we assume here that the coulomb and hund s interaction acting within @xmath2 and @xmath3 orbitals results in a formation of some common local moment ( field @xmath95 ) , while the remaining itinerant degrees of freedom are described by the field @xmath96 formed from the grassmann variables @xmath97 @xmath98 and @xmath99 are the hamiltonian and local self - energy corrections to the lda spectrum ( the latter is assumed to be local and therefore diagonal with respect to orbital indices ) .
the interaction between the two subsystems ( localized and itinerant ) , which are formed from the @xmath5electronic states , is driven by hund s constant coupling @xmath100 . considering the renormalization of the propagator @xmath101 by the corresponding boson self
energy corrections , we obtain for the non - uniform susceptibility ( see supplementary material @xcite ) @xmath102where @xmath103 is the local spin susceptibility and @xmath104 is the exchange interaction , which fulfills @xmath105 ( no spin self - interaction ) .
we find @xmath106 , @xmath107 $ ] is the intra - orbital part , while @xmath108 results from the hybridization of states of different symmetry .
the contribution @xmath109 is approximately twice smaller than @xmath110 and therefore the main contribution to the magnetic exchange comes from the hybridization of @xmath3 and @xmath2 states .
the whole momentum dependence of @xmath111 can be well captured by the nearest
neighbor approximation for effective exchange integrals only , @xmath112 while @xmath109 has more complicated momentum dependence . restricting ourselves by considering the contribution @xmath113 , ( we assume that the contribution @xmath109 is further suppressed by the non - local and vertex corrections ) , from fig . [
fig : inverse_chi ] we find at @xmath72 k the value @xmath114 ev .
this value , as well as the momentum dependence of @xmath111 agrees well with the result of s.v .
okatov et al .
@xcite . the obtained results together with @xmath115 ( see fig .
2 ) provide an estimate for the curie temperature ( we assume @xmath116 ) , which can be obtained from the divergence of @xmath117 : @xmath118and appears comparable with the result of full dmft calculation , and therefore shows that the above model is adequate for describing magnetic properties of the full @xmath119-band hubbard model .
( note that the overestimation of @xmath120 in dmft approach in comparison with the experimental data is due to density - density approximation for the coulomb interactionanisimov and ( to minor extent ) due to presence of non - local fluctuations , not accounted by dmft ) . neglecting longitudinal fluctuations of field @xmath95
we can map the model ( [ sf ] ) to an effective @xmath4 heisenberg model @xmath121 to estimate the spin wave spectrum : @xmath122we obtain the corresponding spin stiffness @xmath123@xmath124 in a good agreement with the experimental data @xmath125@xmath124 ( ref . ) . in conclusion
, we have considered the problem of the description of effective local moments in @xmath0-iron based on the electronic spectrum in paramagnetic phase within lda+dmft approximation .
we find that local moments are formed by both @xmath2 and @xmath3 orbital states , each of them contributing a half of the total moment @xmath126 for @xmath3 electronic states we find pronounced features of non - fermi - liquid behavior , which accompanies earlier observed non - quasiparticle form of @xmath2 states .
the local moment and itinerant states interact with itinerant states via hund interaction , yielding magnetic exchange between the local - moment states via the effective rkky type mechanism .
the obtained exchange integrals are well captured by the lda+dmft approach .
the main origin of the intersite interaction of these moments is attributed to the @xmath2-@xmath3 hybridization , which yields magnetic exchange , dominating on the nearest - neighbour sites .
contrary to the previous studieslichtenstein1987,gornostyrev , we do not however assume some magnetic ordering for the electronic system .
we also emphasize that non
local self energy corrections , as well as vertex corrections , missed in our investigation , can make the described physical picture more precise .
in particular , non - local effects allow for the non zero non - diagonal @xmath2@xmath3 self - energy matrix elements and therefore possibly renormalize the strength of exchange interaction , as well as the self - energy of @xmath3 electronic states .
the role of the vertex corrections , only roughly accounted in the considered approach , also requires additional study .
therefore further investigation using powerful theoretical techniques of dynamic vertex approximation @xcite , dual fermion@xcite , or other non - local approaches is of certain interest .

Over Labor Day weekend in 1995, the site’s founder Pierre Omidyar wrote code for “AuctionWeb” and launched it as a personal project out of a spare bedroom in his Silicon Valley town house. He had bought a $30 laser pointer with the intention of using it to make flashy presentations, but ended up using it to make his cat chase the red dot, according to The Perfect Store: Inside eBay, a book written by former TIME senior writer Adam Cohen. Omidyar decided to list the $30 laser pointer, which broke two weeks after it was purchased, because “it would be a good way to test out AuctionWeb, he figured, and it would cost him nothing,” Cohen wrote. In the listing, he admitted the item didn’t work, even with new batteries. While no one bid on it for a week, a bidding war started the next week, and the product first listed for $1 ended up selling for $14.83. Four years later, Cohen wrote, AuctionWeb — known as eBay — had grown to be an “online retailer valued at more than Sears, or Kmart and JCPenny.” Today, Forbes reports Omidyar’s personal net worth is $8.4 billion and lists the site as one of the “50 most valuable brands in the world.

– Competitive eaters have signed up for an eating contest being bid as the healthiest "in the history of the world." The "Kale Yeah!" championship presented by the Independent Health Foundation's Healthy Options program will take place at the Taste of Buffalo food festival in New York on July 9, where six renowned local competitors are among those willing to stuff their faces with as much kale as possible in eight minutes—including World Buffet Eating Champion "Crazy Legs" Conti and World Watermelon Eating Champion "Buffalo" Jim Reeves, reports UPI. The festival features a variety of foods, including mac and cheese, but it's intended to highlight healthier options by requiring that every vendor serve at least one nutritious item. The contest closely follows its less healthy cousin, Nathan's Famous annual hot dog eating contest, which Joey Chestnut won by downing 70 hot dogs and buns in 10 minutes, notes Eater. It turns out that one must eat nine cups of kale to ingest as many calories as are in a single hot dog. USA Today reports that at least nine people had signed up, and the winner will nab $2,000—which, let's face it, can buy a lot of kale.

The contest takes place July 9, about a week after Nathan's Famous hot dog eating contest. Competitors will down as much of the leafy green as possible in eight minutes on the steps of Buffalo City Hall. That’s a lot of roughage.

"For the first time in human history, the world's greatest eaters will test themselves against the ALMIGHTY KALE—the leafy green vegetable that has captured the hearts and minds of both the culinary set and those for whom their body is a temple," they wrote. "This battle of man vs woman vs kale promises to be the healthiest eating contest in the history of the world." Six competitors from the New York and New Jersey area will participate in the competition, including World Buffet Eating Champion "Crazy Legs" Conti and World Watermelon Eating Champion "Buffalo" Jim Reeves. ||||| Fresh on the heels of Nathan's Famous annual hot dog eating contest (in which Joey Chestnut ate 70 hot dogs and buns in a span of ten minutes), a New York food festival will host a far healthier version of the all-you-can-eat competition: the Kale Cup. According to the AP, the Kale Yeah! contest will take place at the Taste of Buffalo food festival, slated for July 9 in New York. Contestants will have eight minutes to consume as much of the green stuff as possible and the winner will take home $2,000. Though the Taste of Buffalo menu includes things like buffalo mac and cheese and s'mores cupcakes, the contest is meant to highlight the healthier options available at the event; festival rules even stipulate that each vendor must serve at least one healthy item. Fortunately for competitors, eating pounds of kale likely isn't going to have the same effect as eating pounds of, say, hot dogs. While competitive eating has been found to have some serious adverse effects on the human body, you'd have to eat 9 cups of kale to equal the amount of calories in one Nathan's hot dog. (Good luck with that.) |

– It looks like Michelle Carter will be tried for allegedly encouraging her friend to commit suicide in a Massachusetts parking lot last July. A judge refused to dismiss involuntary manslaughter charges against Carter, 18, in a court ruling on Tuesday, though her lawyer says he'll appeal, reports the Sun Chronicle. Conrad Roy III, 18, was found dead of carbon monoxide poisoning in his pickup, which had a gasoline-powered water pump in the back seat. Judge Bettina Borders says phone records show Carter spoke to Roy for 45 minutes while he was believed to be in the truck with the pump running. A text from Carter to a friend indicated Roy got out of the truck at one point, but Carter told him to get back in. "The Grand Jury could find probable cause that her failure to act within the 45 minutes, as well as her instruction to the victim to get back into the truck ... caused the victim's death," Borders says, per the AP. "Even if the defendant did not understand the consequences of her actions, a reasonable person would have realized that telling a person to get back into a truck filled with carbon monoxide would pose a grave risk of danger," she adds. A rep for the Bristol County DA's office praised the decision, noting "we can now focus our efforts on preparing for the upcoming trial." Prosecutors allege Carter pushed Roy to commit suicide so she'd get sympathy, but her attorney released new text messages hours after the judge's decision, noting she tried to dissuade Roy from taking his life throughout June 2014. "Let's get better and fight this together," reads one, per the Boston Herald. "I'm scared for you that you aren't gonna get better and you'll become suicidal again ... Promise me right now that you won't," reads another. A pretrial hearing is set for Nov. 30.

(AP) — An 18-year-old Massachusetts woman who encouraged her boyfriend to kill himself can face an involuntary manslaughter charge, a juvenile court judge ruled. Michelle Carter, of Plainville, sent 18-year-old Conrad Roy III, of Mattapoisett, dozens of text messages in 2014 encouraging him to take his own life. Roy's body was found in his pickup in Fairhaven on July 13, 2014. He died of carbon monoxide poisoning and police found a gasoline-operated water pump in the back seat. On Tuesday, Judge Bettina Borders denied a defense motion to dismiss the involuntary manslaughter charge. Carter's lawyer, Joseph Cataldo, has said that earlier text messages show that Carter tried repeatedly to get Roy to seek help. The defense believes she isn't responsible for the death, and Cataldo said he plans to appeal the decision. In her ruling, Borders cited records that prosecutors say show Carter, then 17, was on the phone with Roy for about 45 minutes while he was inhaling carbon monoxide, heard him moaning and did not call 911. She also cited text messages Carter sent in which she said she told Roy to get back in his truck when he became afraid. "The grand jury could find probable cause that her failure to act within the 45 minutes, as well as her instruction to the victim to get back into the truck after he got out of the truck, caused the victim's death," the judge wrote. A spokesman for the district attorney's office said they were pleased with the New Bedford judge's ruling and they can now focus on the upcoming trial. No trial date has been set yet.

– Police Sgt. Adam Johnson was gripping the reins of two horses when he fired and hit a gunman dead-center in the chest—from 312 feet away, Fox News reports. General reaction from those in the know: Wow. "At a minimum, it was [an] extraordinary shot," says a retired Special Forces man of the bullet that hit Larry McQuilliams, who had reportedly fired over 200 rounds in the streets of Austin, Texas, on Nov. 28, when Johnson's .40-caliber bullet struck him. Other experts applauded him for hitting McQuilliams without bracing himself against anything and firing one-handed while holding the horses, reports the Austin-American Statesman. "It’s not impossible," adds the Special Forces retiree. "Wild Bill Hickok shot bad guys from a hundred yards away with a handgun, but he was also a great shot." Johnson, who had been leading a mounted patrol of twelve officers, is on standard administrative leave following an officer-involved shooting. But he did appear at a charity event Friday and told a radio host that he thanked God, who was at the "right place at the right time."

Adam Johnson raised his service pistol and fired a bullseye into the target some 312 feet away. Down went Larry McQuilliams, and so ended his rampage through the streets of the Texas capital, where he’d fired more than 100 rounds from his AK-47 and .22-caliber rifles at buildings. The shot, from Johnson’s Smith & Wesson M&P .40 pistol, hit McQuilliams square in the chest and made the 15-year-veteran the toast of gun enthusiasts around the country. “At a minimum, it was extraordinary shot,” said Army Maj. John Plaster, a retired Special Forces operator, long-range shooting expert and author of “The Ultimate Sniper: An Advanced Training Manual for Military and Police Snipers.” It was not immediately clear if Johnson’s center-mass shot killed McQuilliams, or if the longtime criminal died from a self-inflicted shot a moment later. Results from an autopsy are pending, but there’s no disputing the improbably accurate bullet fired by Johnson brought a safe end to the Nov. 28 incident.

He’d already shot up the Mexican consulate, the federal courthouse and a downtown bank. “For a guy to keep his composure and holding two horses with one hand and taking a one-hand shot with the other hand, it says a lot about the training and professionalism of our police department,” Austin Police Chief Art Acevedo said to the Austin American-Statesman. Johnson, who works with the Mounted Patrol Unit, was about to get off duty and stabling the horses when he heard shots and returned fire at 2:33 a.m. On Friday, Johnson, who is on routine administrative leave following the incident, made his first public appearance at a holiday charity event.

The Disney (DIS) and Pixar film opened to $136.2 million at the North American box office this weekend. That makes the tale about the forgetful fish voiced by Ellen DeGeneres the biggest opening for an animated film in box office history. It surpassed the record set by "Shrek the Third," which opened to $121.6 million in 2007. "Dory" also nearly doubled the opening weekend of its predecessor, 2003's "Finding Nemo." That film went on to become one of the most popular animated movies of all time making $936.7 million worldwide. "Dory," which opened in 4,305 theaters, swam past expectations that originally projected the film to make roughly $100 million. This was thanks in large part to a strong 95% score on review site Rotten Tomatoes, and families came out in droves to see the film with their children. According to studio data, 65% of the film's weekend audience were families.

recent measurements of the cosmic microwave background radiation by the boomerang and maxima experiments indicate that the universe is spatially flat . here
some simple back - of - the - envelope calculations are used to explain the result .
the main result is a simple formula for the angular scale of the acoustic peak in terms of the standard cosmological parameters : @xmath0 $ ] . #
1to 0pt#1 as we enter the era of precision cosmology , it gets increasingly difficult to understand how cosmological parameters are extracted from observational data .
the cosmic microwave background radiation ( cmbr ) is a prime example .
anisotropies in the cmbr are influenced by a large number of cosmological parameters , including , but not limited to ; the hubble constant ; the spatial curvature ; the spatial topology ; the vacuum energy density ; the baryon density ; the number of light neutrinos ; and the amplitude and spectral index of the primordial density perturbations .
using accurate maps of the cmbr , it should be possible to fix all of these parameters with great precision@xcite .
however , with so many parameters and so many physical effects to keep track of , it is hard to explain how a particular parameter is extracted from the data@xcite .
the aim here is to provide a simple explanation of how the microwave background radiation can be used to measure the spatial curvature .
the test was first proposed by by doroshkevich , zeldovich and sunyaev@xcite , and has subsequently been developed by many authors .
the most comprehensive treatment can be found in the work of hu and white@xcite .
the curvature measurement is based on simple geometry .
if you know the physical size of an object and how far away it is , then by measuring its angular size you can infer the curvature of space .
suppose that the object has size @xmath1 and is a distance @xmath2 away .
in flat space the angle subtended by the object is given by @xmath3 however , if the space is negatively curved with radius of curvature @xmath4 , the angle will be given by @xmath5 notice that ( [ hyper ] ) recovers that flat space result ( [ flat ] ) in the limit @xmath6 .
the expression for a positively curved space can be obtained by replacing @xmath4 by @xmath7 in ( [ hyper ] ) .
to apply the angular size test we need to know the size of a distant object and how far away it is .
when the test is applied to the microwave background radiation , the role of the distant `` ruler stick '' is played by the size of the sound horizon at last scatter , and the distance to the object is the radius of the last scattering surface .
both of these quantities depend on several cosmological parameters , but the spatial curvature turns out to be the dominant effect .
we can measure the angular size subtended by the sound horizon by looking for a special feature in the cmbr angular power spectrum .
the angular power spectrum is obtained by `` fourier '' analyzing the cmbr anisotropy pattern .
sound waves in the photon - baryon fluid with wavelengths roughly twice the size of the sound horizon at last scatter will have just reached a maximum density contrast when matter and radiation decouple .
as we shall see , these waves have periods that are long compared to the time taken for matter and radiation to decouple .
thus , the compression
rarefaction pattern is snap frozen at decoupling .
the enhanced density contrast that occurs on the scale of the sound horizon leads to an enhanced temperature anisotropy , as the cmbr photons are redshifted by an amount proportional to the local density . by measuring the scale at which the peak in the angular power spectrum occurs
, we are able to establish the angular size of the sound horizon .
note : the acoustic peaks are _ density _ peaks , not `` doppler peaks '' .
the fluid is at a turn - around point when maximum density contrast is reached , so the velocity of the baryons , and hence the doppler shift , is at a minimum . before proceeding to show how the angle subtended by the sound horizon
is related to the spatial curvature , a little more non - euclidean geometry is in order . consider a geodesic triangle drawn in hyperbolic space .
the law of cosines reads @xmath8 here @xmath9 are the side lengths and @xmath10 are the opposite angles .
now suppose that @xmath11 , @xmath12 and @xmath13 . using the law of cosines we have @xmath14 and @xmath15 the sum of the angles in the triangle
is given by @xmath16 thus , the angle sum is less that @xmath17 if space is negatively curved , greater than @xmath17 if space is positively curved , and equal to @xmath17 if space is flat . in our cosmological
setting , @xmath1 is the size of the sound horizon , @xmath2 is the radius of the last scattering surface and @xmath18 is the angular scale corresponding to the first acoustic peak .
space is flat if the angle sum in our cosmic triangle adds to @xmath17 .
turning now from the spatial geometry to the spacetime geometry , the unperturbed background geometry is described by the friedman - robertson - walker line element @xmath19 here @xmath20 is the scale factor in units where @xmath21 today , and @xmath22 is the spatial curvature radius today .
the time - time component of einstein s field equations reads ( in units where @xmath23 ) @xmath24 where @xmath25 is the energy density and a dot denotes @xmath26 .
solving for @xmath4 we find @xmath27 where @xmath28 is the hubble constant and @xmath29 is the total energy density today in units of the critical density @xmath30 .
space is negatively curved if @xmath31 , positively curved if @xmath32 and flat if @xmath33 . using conservation of energy - momentum , the friedman equation ( [ fried ] )
can be rewritten in the useful form @xmath34 here @xmath35 , @xmath36 and @xmath37 denote the contributions to the total energy density from radiation ( photons and light neutrinos ) , non - relativistic matter ( baryons and cold dark matter ) , and an unclustered dark matter component with equation of state @xmath38 where @xmath39 .
the unclustered dark matter takes the form of a cosmological constant when @xmath40 .
since angles are conformally invariant , we can use the conformally related static metric @xmath41 the static ( or optical ) metric has the nice property that null geodesics in spacetime correspond to ordinary geodesics in space .
the conformal time @xmath42 is related to the cosmological time @xmath43 by @xmath44 .
our task now is to calculate the size of the sound horizon at last scatter , and the radius of the last scattering surface . to leading order ,
the sound speed in the photon - baryon fluid is equal to @xmath45 , so the sound horizon is roughly @xmath46 times smaller than the conformal time interval between last scatter and the big bang ( or between last scatter and reheating if we are considering inflationary models ) .
thus , the size of the sound horizon is given by @xmath47 the size of the universe at last scatter , @xmath48 , is inversely proportional to the redshift of last scatter , @xmath49 .
the radius of the surface of last scatter is equal to the conformal time interval between last scatter and today : @xmath50
using the same approximations used to derive equation ( [ alp ] ) , we can relate the angle subtended by the sound horizon , @xmath51 , to @xmath52 and @xmath53 : @xmath54 let us begin with a simple case .
consider a matter dominated universe with @xmath55 .
the integrals ( [ sh ] ) and ( [ sls ] ) yield @xmath56 and the angular size of the sound horizon is given by @xmath57 the angle sum in the cosmic triangle is given by @xmath58 note that while both @xmath52 and @xmath53 depend on @xmath59 and @xmath60 , the angles only depend on @xmath60 .
thus , in a matter dominated universe , the position of the first acoustic peak is an excellent measure of the curvature . since the cmbr experiments report their results in terms of angular power spectra , it is conventional to convert the angular scale into its fourier equivalent , the multipole number @xmath61 . for a matter dominated universe , the first acoustic peak in the angular power spectrum
is located at @xmath62 . for more realistic cosmological models , with both radiation and multi - component dark matter ,
the integrals ( [ sh ] ) and ( [ sls ] ) can not be evaluated in terms of simple functions .
approximate forms can be found as a power series expansions in the quantities @xmath63 , @xmath64 and @xmath65 , where @xmath66 is a measure of the curvature and @xmath67 denotes the redshift of matter - radiation equality . to leading order
we have @xmath68 the expression for the radius of the last scattering surface , @xmath53 , is good to within @xmath69 for @xmath70 and @xmath71 - see the appendix for details . the quantity @xmath65 that appears in ( [ fo ] ) is well approximated by @xmath72 where @xmath73 is the hubble constant in units of 100 km s@xmath74 mpc@xmath74 . in order to find a simple expansion for @xmath52
, we can choose either @xmath73 or @xmath75 as a free parameter and expand the quantity @xmath76 as @xmath77 or @xmath78 the first version works best when @xmath36 and @xmath73 are close to the currently favored values of @xmath79 and @xmath80 .
the second version works best if @xmath81 and @xmath82 . putting everything together in ( [ main ] ) we find @xmath83 or ,
specializing to the case @xmath40 and @xmath81 , we find @xmath84 the above expressions for @xmath51 give a good qualitative picture of how the various cosmological parameters affect the location of the first acoustic peak .
we see that the peak position is mainly determined by the curvature , and only weakly dependent on the value of the hubble constant .
the peak position is largely insensitive to the value of the cosmological constant . the angle subtended by the sound horizon is smaller in a negatively curved universe and larger in a positively curved universe .
the angles in the triangle formed by the sound horizon and the earth sum to @xmath85 neglecting photon self - gravity , sound waves in the photon - baryon fluid obey a simple harmonic oscillator equation , and the position of the first acoustic peak corresponds to the angular size of the sound horizon @xmath86 .
however , when photon self - gravity is included , the oscillator equation gains an anharmonic term that shifts the position of the first few peaks . taking this into account , and using standard isentropic initial conditions , and neglecting silk damping , the temperature fluctuations vary as a function of scale as @xcite @xmath87 solving for the position of the first peak , we find @xmath88 so that for @xmath89 @xmath90 the recent mat @xmath91@xcite , boomerang @xmath91@xcite and maxima@xmath91@xcite results locate the first acoustic peak at @xmath92 , @xmath93 and @xmath94 , respectively . using the boomerang results , and allowing @xmath73 and @xmath95 to vary freely over the range @xmath96 and @xmath97 , our approximate formula ( [ fnl ] ) yields a best fit value of @xmath98 .
this result is consistent with the universe being spatially flat , and agrees with the detailed analysis@xcite of the boomerang data . since the curvature is the dominant effect in fixing the location of the acoustic peak , we are able to get a good fix on @xmath60 despite having only one equation for three unknowns @xmath99 . in conclusion
, simple analytic formulas can be found that give good qualitative , and decent quantitative , insight into how the cmbr observations are used to fix the spatial curvature . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | i would like to thank david spergel and wayne hu for patiently and expertly answering all my questions .we made two major approximations in arriving at equation ( [ shap ] ) .the first was to treat the sound speed as a constant , when a more accurate approximation would be to set @xmath100 , where @xmath101 is the baryon - photon momentum density ratio@xcite . keeping the next to leading term in @xmath102 , the size of the sound horizonis given by @xmath103 \nonumber \\\end{aligned}\ ] ] assuming that there are three light neutrino species , the quantity @xmath102 can be written as @xmath104 for reasonable values of the cosmological parameters , we find @xmath105 , so we can negelect the second term in equation ( [ shnext ] ) . the second major approximation was to expand the expression for @xmath107 in terms of @xmath64 and @xmath63 : @xmath108 so long as @xmath109 and @xmath110 , the higher order terms can safely be neglected .figure 1 . shows the percentage error in the first order truncation of @xmath111 as compared to a full numerical evaluation . the fractional error is less than @xmath112 across a wide portion of parameter space , including the interesting region around @xmath113 .our final task is to show that the period of the wave responsible for the first acoustic peak is large compared to the time taken for matter and radiation to decouple .if this were not the case , the anisotropy would not be frozen in and the acoustic peak would be washed out .the conformal period of the wave is given by @xmath114 and the conformal time interval taken to decouple is @xmath115 , where @xmath116 is the redshift interval for decoupling .the ratio of @xmath117 to @xmath118 is given by @xmath119 for reasonable cosmological parameters , we find @xmath120 , which tells us that the acoustic waves are effectively snap frozen when matter and radiation decouple .99 g. jungman , m. kamionkowski , a. kosowsky and d. n. spergel , phys .d*54 * , 1332 ( 1996 ) .j. r. bond , g. efstathiou and m. tegmark , mon . not .. soc . * 291 * , l33 ( 1997 ) .cornish , d.n .spergel & g. starkman , class .* 15 * , 2657 ( 1998 ) . a good tutorial on cmbr physics and parameter fitting can be found at wayne hu shomepage www.sns.ias.edu/@xmath121whu/. a.g .doroshkevich , ya .b. zeldovich & r.a .sunyaev , sov . astron . * 22 * , 523 ( 1978 ) .w. hu and m. white , astrophys .j. * 471 * , 30 ( 1996 ) .a. d. miller , astrophys .j. * 524 * l1 ( 1999 ) .de bernardis , nature * 404 * , 955 ( 2000 ) .s. hanany , astro - ph/0005123 , ( 2000 ) .a. e. lange , astro - ph/0005004 , ( 2000 ) . |

– This might matter in only a parallel universe, but Ashton Kutcher is on the brink of losing his title as Twitter king. He's got nearly 5 million followers, but he's a mere 10,000 or so ahead of Britney Spears. What's more, she's on track to overtake him within a month, reports Mashable, which not only provides a trending graphic but a breakdown of the rivals' tweeting strategy. (His is way better than her "hollow," promotional account, writes Jolie O'Dell.) See his account here and hers here. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Follower counts on Twitter don't really mean anything, of course — still, we are surprised and a bit saddened to learn that the reigning champion and longtime poster boy of Twitter, Ashton Kutcher, may lose his spot as the #1 followed account to Britney Spears. The two are neck-and-neck in the race to hit 5 million followers. This astronomical number is the work of long and diligent work on the part of each entity. Here's what Ashton and Brit each have going for them and against them: Spears' account is almost four months older than Kutcher's. Kutcher actually uses his own account to send personal tweets about things he cares about. Spears' account is managed by her staff and is largely promotional or "BS alerts" when unfavorable tabloid reports surface. Tweets from "Brit" or "Britney" comprise around a third of all tweets from the account. Like many "real" users, Kutcher follows a relatively small group of friends, just 553 people as of today. Spears' account is following nearly half a million others. Kutcher updates his account every few hours, usually via Twitter client Brizzly. Spears' account is updated every few days. Updates are always posted from the web, even when the star tweets she is on location or at an event or party. Kutcher regularly @replies regular users in conversations. The Spears account doesn't engage in conversations but features occasional retweets from Adam Leber, Spears' manager, and Candie's, the brand for which the star is currently shilling. Spears' account gets significantly more @replies and mentions than Kutcher's. Here's a look at the stats according to TwitterCounter: As you may recall, Kutcher was the first Twitter user to reach 1 million followers when he battled CNN for the top spot in April 2009. It's also interesting to note that Kutcher's account ranked far above Spears' in popularity when the Twitter "accept" bug allowed users to force others to follow them back. Basically, there's no dispute as to who is the better, more interesting user of a real-time service for personal updates. Spears' Twitter account is little more than another facet of her marketing machine. But the singer's overall international popularity is apparently enough to gather an army of followers for even a hollow account. What do you think: Would Spears' account have gained more followers than Kutchers' before now if her tweets were more authentic and less promotional? Do you think Twitter users will stage another "follow Ashton" campaign like the one that arose last year during the race with CNN?
