– Today's shutdown-related media darling looks to be a new website called DrunkDialCongress.org. Its creators want you to vent some rage at a member of Congress over the shutdown, and if you're three sheets to the wind while doing so, all the better. It works like so: You call up the site, plug in your phone number, and get a call-back with a slurred automated message. "Is this government shutdown making you want to drink?" it asks. "When I drink I like to tell people what’s on my mind." After that, your call gets forwarded to the office of a random House member. The left-leaning Revolution Messaging is behind the site, but the calls go to Democrats and Republicans alike, notes MarketWatch. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Whether you are a furloughed worker, being forced to work for free, or just fed up at Capitol Hill. Call & Yell at a random Member of Congress Your phone number will be used only once to connect you to a Member of Congress. (By providing my phone number I certify that this is my phone number and I expressly authorize Creative Majority PAC to contact me using automated means of communication). ||||| Reuters Give Boehner a call… maybe. Want more alcohol in your politics? DrunkDialCongress.org is a new site that forwards calls from users to a random U.S. representative’s office, at which point they can complain about the government shutdown, or whatever else is on their mind. The site, which was put up Wednesday night, is produced by Revolution Messaging, a Washington-based mobile strategy company that works for left-left leaning politicians and causes. DrunkDialCongress, however, will forward calls to Democrats and Republicans in the House. More than 1,000 calls have already been made through the site. Ideally, members of Congress will be “saturated” with calls and reminded about the impasse’s real impact on constituents, said Keegan Goudiss, a partner at Revolution Messaging. “A lot of people are fed up with what’s going on,” Goudiss said. You don’t have to be drunk to use the site. Rather, after entering their phone number, users receive a phone call from an inebriated-sounding voice slurring: “Is this government shutdown making you want to drink?…When I drink I like to tell people what’s on my mind…” Once the automated message is complete, users are forwarded to a lawmaker’s office. Goudiss said the site was inspired by reports of lawmakers drinking even as Congress had yet to reach any agreement on spending. –Ruth Mantell Follow Ruth on Twitter @RuthMantell Follow the Capitol Report blog on Twitter @CapitolReport |

– Kim Kardashian is now Kim Kardashian West, at least on her Twitter and Instagram accounts. The move could be a sign this marriage will last longer than 72 days, considering, as the New York Daily News points out, Kim never took the name of her last ex-hubby, Kris Humphries. The Kardashian-Wests are currently honeymooning in Ireland, E! reports, where sources say they're staying in a mansion called Castle Olivier that costs $34,000 per week. Click for more, much more, from their wedding extravaganza last weekend. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Castle Olivier has "seven four-poster bedroom suites, all unique and different from each other," says an insider, noting that the furniture was "custom made for the castle in 2007." The privately owned mansion also hosts the the largest wine cellar in Ireland, which contains some 55,000 bottles of vino! But North West's mom and dad weren't just lying around the castle and taking in the idyllic scenes around them—they were off exploring! A source tells E! News that on Tuesday at 8 a.m., Kim, Kanye and "four other people in their entourage" took off on a biking adventure with Ballyhoura Tourism. "It was a beautiful, clear morning and they saw a huge amount of wildlife," says a source. "They totally immersed themselves into what was on offer. They couldn't believe the views. It was just a totally different part of the world that they had never experienced. They were engrossed in the environment and they enjoyed being able to escape." ||||| khloekardashian via Instagram Kim Kardashian adopted the surname of new husband Kanye West on Twitter and Instagram. Kim Kardashian has gone West. The reality star updated her Twitter and Instagram accounts Wednesday to show that her full name is “Kim Kardashian West.” The name change comes just a few days after she wed Kanye West in a lavish wedding ceremony in Florence, Italy. KimKardashian via Twitter The reality star now goes by ‘Kim Kardashian West’ on her social media accounts. It seems like a good sign that Kardashian adopted her husband’s surname, considering she didn’t do so during her brief marriage to Kris Humphries. But it makes sense that she’d want to go by Mrs. West, considering her infant daughter North also has Kanye West’s last name. The name change comes just one day after Kardashian shared images from her wedding day on Instagram, and shared details about her wedding week on her blog. |

– In a heartbreaking ending to an already tragic story, the 2-month-old giraffe whose mother trampled a US scientist and her 3-year-old son in South Africa earlier this month has died. Katy Williams and son Finn were near their home in Blyde Wildlife Estate when they surprised the mother and calf, and the mother attacked. Both giraffes were to be relocated from the wildlife reserve to another location; the mother survived the move, but the calf did not, the Times reports. "It is with the utmost sadness that we have to break the news that the 2-month-old calf unfortunately did not survive," the board of the estate said in a statement. The estate manager adds that "all necessary precautions were taken and all legal requirements were adhered to," and says everyone involved is "devastated," the New York Daily News reports. As for the Williams family, their lawyer says Katy "understands that it will take time to recover fully‚ but she has a positive attitude and she is surprising doctors with her rapid progress. She is communicating by writing words and sentences on paper‚ and she has written to ask [husband] Sam to thank everyone for their overwhelming support so far on her behalf." A GoFundMe campaign set up to raise money for medical expenses says she is also using sign language. Finn, according to the crowdfunding page, is "stable but still in critical condition, and Sam has stated that he hopes he wakes up so that they can be reunited as a family." The family's lawyer says Finn has been sedated but is beginning to wake up; the severity of his injuries will be better understood when he has regained consciousness. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | “She is communicating by writing words and sentences on paper, and she has written to ask Sam to thank everyone for their overwhelming support so far on her behalf.” ||||| The giraffe cow that seriously injured a mother and son at the Blyde Wildlife Estate in Limpopo was relocated on Tuesday but her two-month-old calf did not survive. Dr Katy Williams‚ 35‚ and three-year-old Finn‚ were injured when they were attacked by the female giraffe at the estate – where they live - outside Hoedspruit on September 3.

we describe the optical emission and the carrier dynamics of an ensemble of self - assembled gaas quantum dots embedded in gap(001 ) .
the qd formation is driven by the 3.6 @xmath0 lattice mismatch between gaas and gap in stranski - krastanow mode after deposition of more than 1.2 monolayers of gaas .
the quantum dots have an areal density between 6 and 7.6 @xmath1 per @xmath2 and multimodal size distribution .
the luminescence spectra show two peaks in the range of 1.7 and 2.1 ev .
the samples with larger quantum dots have red emission and show less thermal quenching compared to the samples with smaller qds . the large qds luminescence up to room temperature .
we attribute the high energy emission to indirect carrier recombination in the thin quantum wells or small strained quantum dots , whereas the low energy red emission is due to the direct electron - hole recombination in the relaxed quantum dots .
optical emitters are one of the key components of optoelectronics and photonics . in spite of the rapid progress in light emitting technology for the visible spectral range during the last decades ,
the realization of efficient light emitters embedded in the silicon environment remains a challenge .
several efforts have been focused on monolithic integration of iii - v light emitters with silicon . among the iii - v compounds , gap has the smallest lattice mismatch to si ( less than 0.4% ) .
conventionally , gap is used in manufacturing low - cost green to orange light - emitting diodes ( leds ) .
gap is , however , similar to si , an indirect band gap semiconductor ( @xmath3 ev ) and useful light emission from it is only possible by doping which results in low luminescence efficiency .
the challenge of high - efficiency light emitters based on gap has recently been approached by exploring the use of epitaxial quantum structures embedded in this material .
the optical emission from several gap - based qds systems has been investigated .
the inp / gap qd system with a lattice mismatch of 7.7% emits light at about 2 ev @xcite and light - emitting diodes based on inp / gap quantum structures emitting in the red to green spectrum have been demonstrated @xcite .
however , it has been found that the inp / gap quantum structures do not always possess a direct heterointerface and depending on the size and geometry of quantum structures the heterointerface can be indirect in both * k * and real space @xcite , or the lowest electron states can be localized at the interface with a mixed @xmath4 character @xcite .
the system inas / gap may provide a stable direct heterointerface due to its higher conduction band offset compared to the inp / gap .
however , the high lattice mismatch of about 11.4% between inas and gap results not only in the formation of volmer - weber islands but also in dislocations @xcite . adding ga into inas reduces the large lattice mismatch and allows the growth of defect - free stranski - krastanow qds .
the ( in , ga)as / gap qds show photoluminescence ( pl ) in the red range @xcite and , depending on the in concentration and the shape the dots , can have direct heterointerface @xcite .
light emitting diodes and electrical injection qd laser have been demonstrated based on this materials system @xcite . in the materials system ( in , ga)as / gap , the gaas / gap has the lowest lattice mismatch of 3.6% but sufficient for formation of self - organized defect - free qds in the stranski@xmath5krastanow mode @xcite .
low - temperature pl of gaas / gap qds at about 1.96 ev has been reported @xcite .
it has been shown that the relaxed gaas / gap qds have a type - i heterointerface with the lowest electronic state at l minima of the gaas conduction band @xcite .
the pseudomorphic gaas / gap quantum wells ( qws ) and qds , however , have type - ii heterointerface @xcite . in this letter , we demonstrate that by controlling the growth of gaas / gap qds , the gaas / gap qds can be changed from an indirect type - ii or type - i system to a direct type - i system with light emission up to room temperature . depending on the growth conditions , the optical emission of the structures peaks between 1.7 and 2.1 ev .
structures were grown in a riber-32p gas - source molecular beam epitaxy ( gsmbe ) system on gap(001 ) substrates .
after oxide desorption , a 0.5 @xmath6 m gap buffer layer at a growth rate of 0.83 @xmath7m / h was grown at 520@xmath8c .
the growth then was interrupted while the substrate temperature was reduced to 450@xmath8c .
then , the desired thickness of gaas was grown at a rate of 0.3 monolayers / s ( ml / s ) .
the resulting structures were capped by 50 nm of gap . during growth
, the process was monitored using reflection high - energy electron diffraction ( rheed ) .
the surface of gap showed a sharp ( 2@xmath94 ) reconstruction .
the rheed pattern remained streaky for the first ml of gaas , indicating 2-dimensional growth and changed to the broken lines for thicker gaas coverage , indicating the formation of qds .
each sample contains one gaas layer with a nominal coverage between 1.2 and 3.6 ml .
( one ml of unstrained gaas is 0.28 nm thick .
) samples for atomic force microscopy ( afm ) were grown without the gap cap layer .
the density and size of qds were characterized using a bruker icon dimension afm with peak force mode @xcite .
fig .
1 depicts the afm images of the samples with nominal coverage of 1.2 ( fig .
1a ) and 1.8 mls ( fig .
1b ) of gaas . according to the afm results , the formation of qds occurs for gaas nominal thickness greater than 1.2 ml and confirms our rheed observation . the lateral size and the average height of qds increase with increasing nominal thickness from 18 nm and 0.9 nm ( 1.8-ml gaas ) to 36 nm and 2 nm ( 3.6-ml gaas ) .
the data are summarized in fig .
1c .
the areal density of qds varies in the range of @xmath10 @xmath2 .
the estimated thickness of the wetting layer using the afm data is between 0.3 - 0.5 nm .
the cross - section image of a capped 1.8-ml sample measured using high - angle annular dark - field scanning transmission electron microscopy ( tem ) provides similar information about the wetting - layer thickness and the size of the qds .
fig .
1d shows the distribution of the height of qds for three different nominal coverage of gaas between 1.8 to 3.6 ml .
the distribution of both height and lateral size seems to be multimodal @xcite .
the similar size distribution has been reported for the gaas / gap qds investigated by tem @xcite .
spectrally resolved cathodoluminescence ( cl ) measurements were carried out using a xiclone ( gatan uk ) cl system attached to an leo 1530 ( carl - zeiss ) field - emission scanning electron microscope .
the cl signal was detected with a peltier - cooled ccd camera .
fig .
2 depicts the cl spectra ( 80 k ) and their corresponding fits from four gaas / gap samples , each consisting of a single layer gaas with nominal thickness between 1.2 and 3.6 mls and a 50-nm gap cap layer . in order to reduce the effect of the luminescence due to the gap buffer
, we applied an acceleration voltage of 5 kv that leads to an effective excitation depth of about 100 nm . the beam current was controlled by varying the microscope aperture size .
the cl spectrum of a gap epitaxial layer is also shown for comparison in fig .
2 .
the cl spectrum of the 1.2-ml sample , which , according to the afm results , consists of a single qw , demonstrates only one emission peak at 2.07 ev .
samples with gaas nominal thickness above 1.2 ml and containing qds show , however , spectra that can be fitted using two gaussian - shaped lines . for thicker gaas
nominal coverage , the total light output increases and the spectra have an overall redshift .
the first emission peak at higher energies ( position a ) shifts from 2.06 ( 1.8-ml sample ) to 1.88 ev ( 3.6-ml sample ) and the second emission peak ( position b ) shifts from 1.93 ( 1.8-ml sample ) to 1.78 ev ( 3.6-ml sample ) .
temperature dependent cl and pl measurements show that the 2.7-ml and 3.6-ml samples emit light up to room temperature , whereas the light output of the 1.2-ml and 1.8-ml samples become negligible for temperatures above 160 k. apparently , the thermal quenching of the luminescence is less for the thicker gaas coverage ; e.g. in the temperature range between 10 and 300 k the light output of 2.7-ml sample decreases more than 30 times and for 3.6 ml sample only 6 times . in order to investigate the carrier recombination dynamics and the origin of the luminescence
, we carried out time - resolved pl between 5 and 300 k. the samples were excited by 80-fs pulses at 388 nm from a mode - locked laser producing an optical pulse train at 82 mhz .
fig .
3a depicts the pl intensity decay of the 3.6-ml sample at 75 k for two emission peaks , a and b. the transients were fitted by a simple exponential decay with a single time constant .
fig .
3b summarizes the energy dependence of the emission decay times for the three different samples represented in fig .
2 .
the decay times for the peak a and b are highlighted .
for all samples , higher emission energy is correlated with slower luminescence decay . as the nominal coverage of gaas
is increased from 1.8 ml to 3.6 ml , the decay time for the peak a decreases from 8.5 ns to 6 ns .
the decay time at peak b changes from 3 ns to 2.4 ns .
increasing temperature results in the shorter decay time as a consequence of the thermally activated non - radiative decay processes ; e.g. the 3.6-ml sample exhibits decay times at 300 k of about 3.1 and 0.9 ns for peaks a and b. our experimental results can be understood as follows : according to the structural investigations , the qw sample ( 1.2 ml ) and the small qds ( less than 1 nm high ) are fully strained . due to the strain , the conduction band minimum of gaas has a shift of 356 mev to higher energy and hence , the @xmath11-like electrons in the gaas are located significantly higher than the x - valley in the gap . in such a case , the favorable optical transition is indirect and occurs between the electrons ( e ) localized at the x state of gap and the heavy - holes ( hh ) in gaas . with increased the gaas coverage , the qds become larger and partially relaxed . depending on the degree of relaxation , the bottom of the @xmath11-conduction band in gaas shifts to lower energy . finally for the fully relaxed qds , the electrons at the @xmath11 state in gaas are localized lower than the x - valley in the gap matrix and the electron - hole transition becomes direct in both @xmath12 and real space .
fig .
4a shows schematically the band alignment of the two extreme situations of a fully strained ( type ii and indirect ) and a fully relaxed ( type i and direct ) gaas / gap heterostructure .
the two arrows indicate the e - hh transition for both cases . from the afm analysis , we know that for nominal thickness above 1.8 ml , a multimodal size distribution fits better to the investigated qds than a single gaussian distribution .
we divide the qds , therefore , depending on their height , into small , intermediate , and large qds .
such arrangement fits to the lateral size distribution , too .
the small qds are strained with an indirect e - hh transition , whereas the large qds are relaxed with a direct e - hh transition .
the electrons localized in the qds with intermediate size are expected to have a mixed @xmath4 nature .
we consider that all of qds contribute to the optical emission and they are the origin of peaks a and b in fig . 2 for nominal thickness above 1.8 ml .
peak a is due to the smaller qds and peak b to the larger qds .
our model is also experimentally supported by the behavior of the luminescence intensity for the samples with different gaas coverage , in particular the ratio between peaks a and b. as can be seen in fig .
2 , an increased nominal coverage of gaas is correlated with a larger total light output and more dominant peak b. we suggest that the increasing of the total light intensity is connected to a transition from a fully strained indirect type - ii qds system ( 1.8 ml sample ) to a relaxed system with direct type - i qds ( 3.6-ml sample ) . for 2.7 and 3.6 ml samples , the large qds are already relaxed and have higher intensity due to the stronger overlap between electrons and holes wave functions in the type - i band alignment . the facts that both samples emit light up to room temperature and the faster decay time for peak b indicate a direct gap and type - i character of large qds in the samples .
the larger qds have light emission at lower energy mainly due to the confinement effect .
the small qds , on the other hand , emit predomintly at position a with a slower decay time and faster thermal quenching , behaving like a type - ii system .
the connection between the increasing of size and the red shift in emission energy with the corresponding band alignment explain the decay time behavior presented in fig .
3b . the probability to have a mixed direct and indirect transition , and finally a direct and type - i qd increases with increasing the size of the qds .
larger dots with type - i band alignment have large overlap between the electron - hole wave functions and hence , faster decay time .
the fastest measured decay time of about 2 ns is still higher than the reported values for the pure type - i systems , but it can be explained by the mixed direct - indirect nature of the optical transitions . generally , at the interface of two semiconductors , with their conduction band minima at two different valleys , the formation of localized interface states is expected .
such states may have also mixed @xmath4 character and lead to optical transition , particularly for a common anion heterointerface . however , in the case of gaas / gap with a common cation heterointerface the interface states are not localized in the gap and are not optically active , as predicted by atomic empirical pseudopotential calculations @xcite .
the appearance of peak a and b in luminescence spectra shows that both kinds of transition occur simultaneously in a mixed ensemble of type - i and type - ii qds .
the excitation intensity dependence of the pl measurements in the range of 0.001 to 10 w/@xmath13 verifies this picture and shows a remarkable 50 mev blueshift for peak a and a slight blueshift of about 6 mev for peak b for the 3.6-ml sample .
the strong blueshift has already been reported for several type - ii qds @xcite . in order to corroborate our model , we calculated the energy states of gaas / gap qws and qds using the effective mass approximation for different relaxation degree @xcite .
since the height of the qds is at least one order of magnitude smaller than their lateral size , the qds were modeled as qws with a thickness equivalent to the height of the qds . according to the calculation
, a direct e - hh transition in gaas qds is expected only if the qds are higher than 2 nm and fully relaxed .
fig .
4b depicts the calculated energetically lowest and favorable e - hh transition for fully strained , 75% strained , and fully relaxed qds as a function of the height .
the symbols show the peak positions of samples with nominal coverage between 1.2 ml to 3.6 ml .
the corresponding height for every peak position was taken from afm analysis and gives the average height of small and large qds in every sample .
the luminescence peak positions fit well to the calculated results .
these results support our model for a transition from optically low - efficient indirect type - ii strained qw and qds to optically efficient direct type - i relaxed qds while the size of dots increases .
the strain relaxation in the gaas / gap qds occurs via the formation of edge dislocations , which do not act as nonradiative recombination centers and hence , allows the realization of high - efficient e - hh transition @xcite .
similar characteristics have been also reported for the qds based on the direct gap ingaas embedded in the indirect gap matrix @xcite .
several stranski - krastanow qds systems such as ( in , ga)as / gaas and inas / inp show luminescence spectra with two peaks , which are attributed to the qds and to the wetting layer .
however , the emission energy of gaas / gap qds is very low for the strained wetting layer with an estimated thickness of @xmath14 nm .
therefore , we believe that the origin of the light emission is the carrier recombination in the qds . only for 1.8-ml sample the origin of peak a might be the fully strained wetting layer . in summary
, we have demonstrated the optical emission of the gaas / gap qds up to room temperature in the visible range .
the luminescence spectra can be fitted using two gaussians .
the afm analysis shows a multimodal size distribution for the qds .
the thin quantum wells and small dots are fully strained and have type - ii band alignment with indirect e - hh transition , whereas the large qds are fully relaxed with type - i band alignment and direct e - hh transition .

– The world may have a surprise new "oldest person," and by a good margin, reports AFP. A daily newspaper in Guatemala reports that a woman named Juana Chox Yac has a government birth certificate that puts her age at 120. That would make her four years older than the current No. 1, Japan's Misao Okawa. But the Washington Post notes that the two leading authorities on such matters—the Guinness Book of World Records and the Gerontology Research Group—apparently have yet to confirm. Yac is an indigenous Mayan who was born in a farming village called Santa Lucia Utatlan. She married at 15 and had two kids, but her husband died nine years later. She remarried at age 29 and had seven more children before becoming a widow for the second time in 1964. Government officials describe her as "lucid" and looking forward to her 121st birthday in November.

Juana Chox Yac, who is an indigenous Kaqchikel Maya, was born November 29, 1893 in the farming village of Santa Lucia Utatlan, Solola department, the report in the daily Siglo 21 said. As a young woman, she worked picking coffee beans, and tending sheep and goats, before marrying at 15, the newspaper said. Her first husband died nine years after they were married and their two children have died as well. Chox Yac however remarried at 29 and had seven more children before being widowed again in 1964. She has a family of 75 relatives including children, grandchildren, great-grandchildren and great-great-grandchildren, said the report, which published a government document with her birth date. It was not immediately known if her details have been submitted to the Guinness Book of World Records for verification. But the report puts her age at four years older than Japan's Misao Okawa, who turned 116 on March 5 and is the book's official record holder for longest-lived woman. ||||| Please enable cookies on your web browser in order to continue.

– Hiring picked up in August as US employers added a stronger-than-expected 201,000 jobs, a sign of confidence that consumers and businesses will keep spending despite the Trump administration's conflicts with trading partners, per the AP. The Labor Department says the unemployment rate remained 3.9%, near an 18-year low. Americans' paychecks grew at a faster pace. Average hourly wages rose in August and are now 2.9% higher than they were a year earlier, the fastest annual gain in eight years. Still, after adjusting for inflation, pay has been flat for the past year. The economy is expanding steadily, fueled by tax cuts, confident consumers, greater business investment in equipment, and more government spending. Growth reached 4.2% at an annual rate in the April-June quarter, the fastest pace in four years. The good news might not necessarily be a boon for investors.

The sector was little changed last month on the employment front, losing 3,000 jobs, a slowdown for one of the economy's bright spots in recent months. Although the dip ended a streak of 12 consecutive months of job additions, the group is still up 254,000 jobs in the past year. Some lukewarm manufacturing data points have started to worry some analysts, and investor sentiment toward large U.S. manufacturs has also taken a hit due to continuing trade fights. Dean Baker, a senior economist at the Center for Economic and Policy Research, notes that wage gains also grew 1.8% from a year earlier in the sector, lagging behind other groups. "While it is far too early to determine if the Trump administration's trade policy is responsible for this weakness, it seems clear that it is not showing obvious benefits at this point," he says in a note. But even with the drop off for the manufacturing sector, strength in professional and business services, health care and construction lifted the headline jobs number. |

– The rail dispatcher in charge of two trains that collided in Germany in February, killing 11, was playing a game on his phone just before the crash, authorities say. The man, whose name is not being released but who is a 39-year-old with years of experience, has been arrested on suspicion of negligent homicide, the Wall Street Journal reports. The collision near Munich Feb. 9 was one of the worst rail accidents in Germany's recent history, and no technical problems have been found to have contributed, the AP reports. "Due to the close timing it must be assumed that the accused was distracted from controlling the cross-traffic of the trains," prosecutors say in a statement, adding that the dispatcher had been actively playing the cellphone game for "an extended period of time" until shortly before the collision. He likely gave the trains the incorrect signals, then pressed the wrong combination of buttons while trying to issue an emergency call, meaning the train drivers probably never heard it. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | BERLIN (AP) — A German rail dispatcher was playing an online game on his cellphone shortly before two trains he was in charge of collided on a single-track line, killing 11 people, prosecutors said Tuesday. The unnamed dispatcher was arrested on suspicion of negligent homicide, prosecutors in the Bavarian town of Traunstein said in a statement. The two trains were filled with commuters when they collided head-on Feb. 9 near the town of Bad Aibling, about 60 kilometers (40 miles) southeast of Munich. It was one of Germany's worst rail accidents in recent history. Prosecutors said the man had been actively playing the game on his cellphone for "an extended period of time" until shortly before the crash. Rail dispatcher rules forbid the use of personal cellphones at work. "Due to the close timing it must be assumed that the accused was distracted from controlling the cross-traffic of the trains," the statement said. This likely led the dispatcher to give the trains the wrong signals and then, once he noticed his error, to fumble the emergency call by pressing the wrong combination of buttons, meaning the train drivers were unable to hear it, prosecutors said.

– This might just be a weird coincidence, or Tim Tebow's dramatic defeat of the Steelers last night may have been a miracle in more ways than one. The polarizing Denver quarterback wound up throwing for 316 yards, which, if you toss in a colon in the right spot, mirrors the call number of a famous bible verse, John 3:16. That's a verse Tebow occasionally wrote on his face while playing at the University of Florida, Fox News reports. Not weird enough for you? Well, Tebow threw those 316 yards over the course of 10 completions, meaning he averaged 31.6 yards per completion. Wait, there's more: John Ourand of the Sports Business Journal tweeted that the TV rating for the last 15 minutes of the game was—you guessed it—a 31.6. Was this some kind of divine product placement? Probably not, but if it was it worked: As of this writing, John 3:16 is No. 1 on Google Trends. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Tim Tebowed and Denver rose as one. The Broncos quarterback's 80-yard touchdown pass to receiver Demaryius Thomas on the first play of overtime against Pittsburgh both clinched Sunday's game and wrote another improbable chapter in Tebow's book of clutch plays to win high-pressure games. His performance also borrowed a little magic from another famous book. The devout Christian's stat line in Sunday's game mirrors the numbering of the Biblical passage that Tebow at times had painted on to his black eye paint during his career at the University of Florida -- John 3:16. The passage reads, according to the New American Standard Bible, "For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life." Officially, Tebow passed for 316 yards against the Steelers, completing 10 of 21 pass attempts -- meaning he passed for 31.6 yards per completion. After his final pass was caught and brilliantly taken downfield by Thomas, Tebow shrugged off three bad weeks -- when he threw for just one touchdown and four interceptions -- and took a knee and prayed in his classic style. "First and foremost, I just want to thank my savior, the Lord, Jesus Christ," Tebow said at the postgame press conference. "I am so thankful for the platform God has given me." Next up for those on the Tebow bandwagon, a trip to New England to tackle Tom Brady and the Patriots in the AFC divisional playoff game on Saturday. ||||| Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.

– A "badass" guitar designed for women is coming to market in March, Esquire notes, and female shredders have Annie Clark to thank for it. Clark, better known as alternative rocker St. Vincent, has designed a signature guitar for manufacturer Ernie Ball Music Man, and as Clark notes on Instagram, the instrument is "ergonomic, lightweight, and sleek"—and by "sleek" she means there's "room for a breast … or two." The guitar, which comes in black or "Vincent Blue" (which the artist hand-mixed herself), is made of African mahogany with a rosewood neck, has a slim and tapered waist, and weighs just over 7 pounds, per Guitar World. "For me a guitar that is not too heavy is really important because I'm not a very big person," she tells the magazine. "I can't even play a ['60s] Strat or ['70s] Les Paul. I would need to travel with a chiropractor on tour in order to play those guitars." Clark, who notes she "really had total free reign" over the design, says she was approached by Ernie Ball in the early spring of 2015 and had worked up a first prototype within a week of visiting the factory (there have been many other versions since her collaboration with Ernie Ball engineers). While creating it, she took into account how its weight would be distributed, as well as the fact that she didn’t want it to cover up what she considers to be one of a female performer's best features: her waist. In the end, though, it’s all about the music. "If you have a great instrument you're going to play better," she says. "You're going to play up to the level of the instrument because it makes it easier for you to succeed." Her first public performance with the guitar?

– A Florida man's cunning plan to smuggle drugs in his ample stomach fat was foiled because he was too big to fasten his seat belt. Police say that after 450-pound suspect Christopher Mitchell—whose aliases include "Fat Boy" and "Biggie"—appeared nervous during a traffic stop, a drug-sniffing dog was called in and a search turned up 23 grams of marijuana stashed under rolls of fat, the Smoking Gun reports. Cocaine, a handgun, and $7,000 in cash stuffed into a sock were also found during a search of the vehicle, which was pulled over when a deputy spotted that Mitchell didn't have a seat belt on, the New York Daily News reports. The 42-year-old suspect, who weighed around 200 pounds less when he was convicted of conspiracy to traffic cocaine in 2002, was charged with marijuana possession as well as failure to wear a seat belt. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Police: 450-Pound Florida Man Had Marijuana Stashed In His "Stomach Fat" Share Tweet A 450-pound Florida man was arrested yesterday after cops conducting a traffic stop discovered that he had stashed marijuana under his stomach fat. Christopher Mitchell, 42, was traveling in a vehicle driven by Keithian Roberts, 38, when the car passed a sharp-eyed Volusia County Sheriff’s Office deputy who noticed that the 5' 6" Mitchell was not wearing a seatbelt. During a subsequent traffic stop, both men reportedly appeared nervous, prompting the cop to summon a drug-detection dog. Mitchell, investigators noted, claimed to be so big that he was unable to buckle himself in. After the drug dog alerted to the presence of narcotics in the vehicle, officers searched Mitchell, Roberts, and the car. Investigators found "23 grams of marijuana hidden under Mitchell’s stomach fat,” a handgun, $7000 in cash, and some cocaine (for which Roberts was hit with a possession charge). Mitchell, seen in the above mug shot, was also cited for failure to wear a seat belt. Additonally, deputies noticed that the car’s trunk and its interior were “sprinkled with carpet freshener and scented dryer sheets, a common tactic used to conceal the odor of drugs when they’re being transported,” according to a news release which does not reveal which unfortunate deputy had to excavate the pot from Mitchell's stomach cave. According to Florida Department of Corrections records, Mitchell was previously convicted of cocaine trafficking (for which he served three years in prison). Mitchell, who was freed in December 2004, had several aliases, including “Biggie” and “Fat Boy.” His weight a decade ago was 265 pounds, jailers reported.

– In a Twitter storm on Tuesday, Donald Trump implied he'd been chained to the Republican Party for too long. But in the wake of recent denouncements from dozens of Republicans, including Paul Ryan, "the shackles have been taken off me and I can now fight for America the way I want to," he said, per Politico. In what is widely viewed as evidence of a widening rift in the Republican Party, Trump went on to bash Ryan as a "very weak and ineffective leader" and label Democrats—"with the exception of cheating Bernie"—as "far more loyal to each other" than Republicans. "Despite winning the second debate in a landslide (every poll), it is hard to do well when Paul Ryan and others give zero support!" he continued, adding, Republicans "are far more difficult than Crooked Hillary." Bustle's take: Trump's "going rogue and it could get scary." In response, a rep says Ryan "is focusing the next month on defeating Democrats, and all Republicans running for office should probably do the same," per USA Today. Despite several GOP members calling on Trump to remove himself from the presidential race, the nominee vowed Tuesday to teach Republicans "how to win." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Donald Trump’s tweet was a tacit attack on House Speaker Paul Ryan. | Getty Trump: 'It is so nice that the shackles have been taken off me' Donald Trump celebrated his freedom from the Republican establishment Tuesday, boasting that it’s “so nice” to be unchained.

– President Obama secretly penned a letter to Ayatollah Khamenei last month, sources tell the Wall Street Journal, in an attempt to prod the Iranian leader toward a nuclear deal while simultaneously underscoring the two nations' joint interest in fighting ISIS—with any cooperation on the latter being what the Journal calls "largely contingent" on the former. Senior American officials wouldn't talk about the letter, and NPR notes that White House Press Secretary Josh Earnest said today that he's "not in a position to talk about private correspondence between the president and another world leader." Khamenei has reportedly never directly responded to any of Obama's previous three letters. The US and Tehran have shared warmer relations since the election of Hasan Rouhani, but it's not clear how far Obama's going to get with Khamenei. Obama himself said yesterday that "there’s a sizable portion of the political elite that cut their teeth on anti-Americanism," and that "whether they can manage to say 'yes' ... is an open question." Khamenei as recently as last month blamed "America, Zionism, and ... the wicked government of Britain" for creating "al-Qaeda and (ISIS) in order to create divisions and to fight against the Islamic Republic, but today, they have turned on them." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | WASHINGTON—President Barack Obama secretly wrote to Iran’s Supreme Leader Ayatollah Ali Khamenei in the middle of last month and described a shared interest in fighting Islamic State militants in Iraq and Syria, according to people briefed on the correspondence.

The letter, according to the newspaper, was about the U.S.-led fight against the so-called Islamic State. The Journal reports: "The letter appeared aimed both at buttressing the Islamic State campaign and nudging Iran's religious leader closer to a nuclear deal. "Mr. Obama stressed to Mr. Khamenei that any cooperation on Islamic State was largely contingent on Iran reaching a comprehensive agreement with global powers on the future of Tehran's nuclear program by a Nov. 24 diplomatic deadline, the same people say. "The October letter marked at least the fourth time Mr. Obama has written Iran's most powerful political and religious leader since taking office in 2009 and pledging to engage with Tehran's Islamist government." During his regularly scheduled press briefing, White House Press Secretary Josh Earnest was asked about the report and responded that he was "not in a position to talk about private correspondence between the president and another world leader." Earnest said U.S. policy on Iran "remains unchanged" and that the United States has engaged in talks with Iran about its nuclear program and on the sidelines of those talks, it has also addressed the U.S.-led offensive against the Islamic State. Earnest said the U.S. "will not cooperate militarily" and will not share intelligence with Iran. |

we study the effect of a many - body interaction on inter - band oscillations in a two - band bose - hubbard model with external stark force .
weak and strong inter - band oscillations are observed , where the latter arise from a resonant coupling of the bands .
these oscillations collapse and revive due to a weak two - body interaction between the atoms .
effective models for oscillations in and out of resonance are introduced that provide predictions for the system s behaviour , particularly for the time - scales for the collapse and revival of the resonant inter - band oscillations .
_ introduction .
_ recent experiments proved the possibility to study the coherent dynamics of interacting many - particle systems @xcite .
such realisations of many - body systems with ultra - cold gases in optical lattices have a short but impressive history and open immense possibilities for various fields of physics @xcite .
the demonstration of the well - known phenomenon of collapse and revival , the latter being a pure quantum effect , with ultra - cold atoms bears witness of this coherent evolution of a many - body wave function @xcite .
additionally , the high degree of control in such experiments allows a manipulation of many system parameters and makes them particularly interesting for various fields of physics as well as future applications @xcite .
different ways of addressing additional degrees of freedom in such ultra - cold bosonic gases have been suggested @xcite . in the present fast track communication
, we discuss a two - band model with an additional external force to control the coupling between the two bands . applying a force to atoms in optical lattices leads to bloch oscillations and
is a realization of a many - body wannier stark system @xcite .
the coupling of the low - lying energy bands in such systems has been demonstrated in different experiments , e.g. on landau - zener tunnelling @xcite and the influence of the many - body interaction on a weak coupling of the bands has also been studied theoretically @xcite .
we go beyond a weak coupling of energy bands and consider an isolated two - band system with a strong external force .
a closed two - band system is an idealisation but can be realised approximatively with ultra - cold atoms @xcite using different techniques as , e.g. , super lattices @xcite .
besides the possibility of experimental realisation , a closed two - band model is also interesting as a simple model system . for the latter , we focus on the two lowest energy bands of interacting bosons in a optical lattice @xmath0 , with the wave vector of the optical lattice @xmath1 .
then , all parameters of the model hamiltonian just depend on this external potential .
the parameters can be computed numerically ( see , e.g. , appendix a in @xcite ) and analytical approximations exist for them for not too small amplitudes @xmath2 @xcite . using this setup , we are able to identify regions of strong and weak inter - band coupling .
a weak two - body interaction introduces new energy scales in the coherent evolution of the many - body wave function , leading to a collapse of such oscillations , but the form of the interaction gives rise to subsequent revivals .
we give analytical expressions for all time - scales in this many - body realisation of a two - band collapse and revival phenomenon , and experimental ramifications for a realisation with ultra - cold bosonic gases are discussed . _ the many - particle model .
_ we study a two - band bose - hubbard model with an additional external stark force for a strong coupling of the two bands , introduced in @xcite @xmath3 . } \ ] ] here , @xmath4 ( @xmath5 ) annihilates ( creates ) a particle at site @xmath6 of totally @xmath7 sites in the lower band and @xmath8 ( @xmath9 ) in the upper band .
the corresponding number operators are @xmath10 , @xmath11 .
the bands are separated by a bandgap @xmath12 and have onsite - energies @xmath13 , respectively .
we include hopping between neighbouring sites in band @xmath14 with a hopping strength @xmath15 , and a repulsive interaction between particles occupying the same site in band @xmath16 with a strength @xmath17 .
the two bands are coupled via @xmath18 , with the external stark force @xmath19 and a coupling constant @xmath20 depending on the depth of the lattice @xmath2
@xcite , and also via the inter - particle interaction with a strength @xmath21 .
all parameters are measured in recoil energies @xmath22 and we set @xmath23 troughout .
focussing on a realisation with a single optical lattice rather than a superlattice , the relation between the parameters is generally : @xmath24 , as well as @xmath25 and @xmath26 .
we take the external force @xmath19 as a free parameter .
we assume that the interaction strength can be tuned ( experimentally , e.g , by the use of feshbach resonances @xcite ) and include a corresponding scaling factor @xmath27 to all interaction terms . to study the occupation of the upper band , we prepare the system in an initial state @xmath28 , with a uniform distribution of particles in the lower band only and evolve it in time by the many - body schrdinger equation .
the quantity we study is the ( normalised ) number of particles in the upper band @xmath29 where @xmath30 is the total number of particles .
we will refer to @xmath31 as _ occupation of the upper band_. let us discuss the non - interacting single - particle case @xmath32 first .
we apply the following transformation involving bessel functions of the first kind @xmath33 to our operators , which is known to remove the hopping terms in the single - band case @xcite @xmath34 with @xmath35 , @xmath36 . using relations for bessel functions , we arrive at @xmath37,\ ] ]
where @xmath38 and @xmath13 as above .
we obtain coupling between any two sites of the two different bands , weighted by bessel functions . in the coupling between different and possibly remote sites
originates from an on - site coupling and subsequent hoppings .
it can thus be considered a higher order process in the original basis .
but in the transformed hamiltonian , this coupling is now direct with a strength modified by the factor @xmath39 .
the hilbert space in the many - particle problem is spanned by fock states with fixed particle number @xmath40 with single - particle basis @xmath41 .
the total dimension of the fock space for a given number of atoms @xmath42 and lattice sites @xmath7 per band is given by @xmath43 $ ] . for numerical simulations ,
we change to the interaction - picture with respect to the external force @xcite which removes the tilt @xmath44 and replaces @xmath45 ( and likewise for @xmath46 ) .
the hamiltonian is then time - dependent with a periodicity of @xmath47 and decomposes into a direct sum of operators for specific quasi - momenta @xmath48 @xcite . as a consequence
, the size of the hilbert space is reduced by a factor of the order of @xmath7 @xcite .
since the different subspaces are physically equivalent , we restrain our discussion to the @xmath49-subspace of the hilbert space @xcite . + for the time - evolution of a given initial state , we use either a direct numerical integration ( with an adaptive step - size runge - kutta algorithm @xcite ) or an eigenbasis expansion after diagonalising the problem : @xmath50 here we use the eigenstates @xmath51 of the floquet - bloch operator ( @xmath52 denotes time - ordering ) @xmath53,\ ] ] since the hamiltonian is explicitly time - dependent , with a periodicity @xmath54 . in addition , this gives us the full spectrum and enables access to relevant energy scales of the problem , as well as an identification of the most important states participating in the time - evolution .
_ results .
_ for the specific system under consideration , i.e. , bosons in optical lattices , both hopping coefficients @xmath55 are smaller than unity and ( since we are interested in strong inter - band coupling ) we take the external stark force @xmath19 to be much larger than the hopping coefficients : @xmath56 .
the non - interacting hamiltonian now allows for simple solutions for two regimes : values of the external force @xmath19 not leading to a degeneracy between energy levels of different bands ( _ off - resonant _ regime ) and values of the force @xmath19 leading to such a degeneracy ( _ resonant _ regime ) .
for the off - resonant regime we make use of @xmath57 and neglect all bessel functions in except for @xmath58 .
the hamiltonian then decomposes @xcite into a sum of independent two - level systems and the occupation of the upper band when initially zero follows a simple rabi formula @xmath59^{-1}\sin^2 ( \tilde\delta t/2)$ ] , where @xmath60 .
this corresponds to rabi oscillations between the bands with an amplitude much smaller than unity and a period @xmath61 of the order of the _ bloch period _ @xmath62 .
an example is shown in the lower panel of where the off - resonant contribution to the oscillations is shown .
although the coupling from a site @xmath6 to sites in the other band with different index @xmath63 is usually small ( cf . discussion after ) , it is important when the two levels become degenerate in energy , i.e. , for resonant values of the force @xmath19 .
this happens when the energy gap between both bands is close to an integer multiple of the external force @xmath64 and we refer to this regime as _ resonant of order @xmath65_. in resonance , the coupling of the degenerate levels is most important and the hamiltonian of can similarly be reduced to a sum of independent two - level systems @xmath66,\ ] ] and diagonalised by @xmath67 and @xmath68 .
the resonant oscillations ( of order @xmath65 ) between the two bands have an amplitude of almost unity and a period given by @xmath69 an example of these resonant oscillations for @xmath70 is shown as the thin dashed line in . the period predicted by the reduction to independent two - level systems
is @xmath71 for the parameters given there , in excellent agreement with where the actual period is @xmath72 .
we found equally good agreement in numerical simulations for different lattice depths and other orders @xmath65 of resonance not explicitly reported here .
let us now study the effect of the many - body interaction in the original hamiltonian
. also shows the occupation of the upper band as a function of time for the initial state @xmath73 in a weakly interacting system with @xmath74 .
we observe a decay of the resonant oscillations followed by a major revival . at later times
several minor revivals occur ( not shown in ) .
this effect is stable against variations of the system parameters ( as number of particles and lattice sites , even for fillings @xmath75 of order but not always close to one ) , with the time scales of decay and revival depending on the interaction strength @xmath27 ( see the following section and ) .
we found the same phenomenon with different initial states in numerical simulations as long as the particles are mainly delocalised along the lattice and occupy only the lower band , i.e. , excluding fock states with all particles on one lattice site for instance .
the oscillatory behaviour depicted in strongly reminds of the collapse and revival effect known from quantum optics @xcite .
a specific feature in these systems is a linear dependence of the collapse and revival time on the inverse coupling strength , i.e. @xmath76 and @xmath77 where @xmath27 usually denotes the coupling strength between the light field and the two - level atom in the quantum optical systems @xcite .
we verified numerically for our system that the observed decay and revival times obey a similar dependence with the interaction parameter @xmath27 as coupling strength in our model .
we define @xmath78 as the time when the difference between the maximal and average amplitude of the inter - band oscillations has fallen to @xmath79 , i.e. , @xmath80 . the revival time is taken as the maximum of the revived oscillations .
clearly demonstrates the linear dependence of these times on the inverse interaction strength . to find an effective description , we try to understand the most relevant interaction processes
clearly , the repulsive two - body interaction disfavours double occupancy of sites since this will always cost an interaction energy @xmath81 for two particles occupying the same site in the lower ( upper ) band .
starting from an initial state with population of the ground band only , the strong stark force leads to an occupation of the upper band .
doubly occupied sites are also suppressed there , but two particles may sit at the same site in either band , i.e. on top of each other " . indeed , the most important interaction term in the time - evolution is @xmath82 , since it already gives a non - zero contribution when there is only one particle per site in each of the two bands .
in fact , comparing the time evolution of the initial state with all interaction terms and only the one mentioned shows almost no difference ( cf . ) .
we focus on fillings close to unity @xmath83 and study the time - evolution of states of the form @xmath84 , which is not an eigenstate of the system in resonance . note
that this is the most important contribution to the superfluid ground state in an expansion in our configuration state fock basis . for large enough systems the superfluid ground state of the untilted system ( and the single - occupancy state @xmath85 likewise ) becomes indistinguishable from a coherent state ( eq . ( 66 ) in @xcite ) that factorises into a product of local coherent states at each site @xmath6 : @xmath86 |{\rm vac}\rangle = \prod_l \big ( \rme^{\sqrt{\bar n } a_l^{{\dagger } } } |{\rm vac}\rangle_l\big ) = \prod_l |\varphi ; 0\rangle_l \equiv |\boldsymbol \varphi ; 0\rangle.\ ] ] we denote this coherent state with phase @xmath87 by @xmath88 .
we are now going to re - write this state in the resonant basis and determine the effect of the interaction term @xmath89 when acting on this state .
we start by inserting the transformation @xmath90 into to obtain @xmath91 |{\rm vac}\rangle \nonumber\\ % & = { \rm exp}\bigg[\sqrt{\frac{n}{2l}}\sum_{l , n}j_{l - n}(x_a)(\mu_n^{\dagger}- \nu_n\dag ) \bigg ] |{\rm vac}\rangle \nonumber\\ & = \prod_n \rme^{\sqrt{\bar n/2}\;\mu_n^{\dagger } } \rme^{-\sqrt{\bar n/2}\;\nu_n^{\dagger } } |{\rm vac}\rangle .
% \equiv \prod_n\big|\frac{\varphi}{\sqrt{2 } } ; -\frac{\varphi}{\sqrt{2}}\big)_n.\end{aligned}\ ] ] where we used @xmath92 $ ] for @xmath93 @xcite and @xmath94=0 $ ] which follows from the properties of the operators @xmath95 .
let us denote fock states with single - particle basis @xmath96 by round parentheses @xmath97 .
from we see , that the coherent state of the lower band in resonance is a product of local coherent states for both bands in the resonance basis @xmath98 with @xmath99 .
the time - evolution of this state ( for the non - interacting system in resonance ) is simple since it is diagonal in the eigenbasis of the hamiltonian in resonance .
we continue to study the phase evolution created by the most important term @xmath89 perturbatively by expressing the operators @xmath100 in the @xmath101-basis : @xmath102 |\boldsymbol{\tilde\varphi } ; -\boldsymbol{\tilde\varphi } ) = \exp\bigg[\frac{\rmi gw_x t } { 2}\sum_{l}\sum_{l_1,\ldots , l_4 } j_{l - l_1}(x_a)j_{l - l_2}(x_a)j_{l - l_3}(x_b ) \times \nonumber\\ j_{l - l_4}(x_b ) ( \mu_{l_1}^{\dagger } - \nu_{l_1}^{\dagger})(\mu_{l_2 } - \nu_{l_2})(\mu_{l_3}^{\dagger}+ \nu_{l_3}^{\dagger})(\mu_{l_4 } + \nu_{l_4})\bigg ] |\boldsymbol{\tilde\varphi } ; -\boldsymbol{\tilde\varphi}).\end{aligned}\ ] ] since @xmath103 is a product of local coherent states we can ignore the sum over @xmath6 and discuss the expected behaviour .
firstly , both @xmath104 are much smaller than unity and the main contribution in the sums over @xmath105 will come from the zeroth - order bessel functions @xmath106 . secondly , the product of operators gives @xmath107 different combinations of the field operators .
but due to the prefactors , the combinations with equal indices are the most important .
they simply give an integer number when applied to the product of local coherent states they are acting on . taking these two points together , the time evolution of this state should show an approximate revival at @xmath108 this result is valid for large systems and can not account for the effect of non - universal properties like a limited number of particles and lattice sites , but we expect it to yield the right order of magnitude for finite systems , and in particular the correct scaling with the parameters of external potentials ( c.f .
, inset , below ) .
additional finite size corrections to can be understood by using the decomposition into the eigenbasis .
the evolution of the occupation of the upper band certainly depends on the initial state , which we can take into account by studying the weights @xmath109 of the initial state expanded in the eigenbasis .
the result of a numerical diagonalisation for a system in resonance is depicted in , where the absolute values of the expansion coefficients with their corresponding quasi - energies are shown .
for vanishing two - body interaction strength @xmath110 , the quasi - energies from the states with different occupation numbers are degenerate as expected .
the energy difference between neighbouring lines of constant quasi - energies corresponds to the time - scale of the resonant inter - band oscillations and follows from the diagonalisation of the resonant non - interacting system as @xmath111 . in the non - interacting system ( @xmath110 )
, two coefficients are dominating and the difference of the quasi - energies yields a single time - scale @xmath112 .
when the interaction is turned on , the weight of states with many contributions from double- or higher occupancies of sites decrease significantly ( since they are energetically disfavoured ) and their quasi - energies are slightly shifted .
but , surprisingly , only a limited number of additional coefficients @xmath109 contributes significantly in the eigenbasis expansion even for @xmath113 .
the observed collapse and revival signal is now determined by a few expansion coefficients that are much larger than the others .
if we focus on the three largest coefficients , denoted as @xmath114 and sorted by their quasi - energies @xmath115 , we find that the latter are shifted by the interaction by different amounts . the differences between neighbouring quasi - energies , @xmath116 and @xmath117 ( shown for the example @xmath118 in ) , lead to a beating between two oscillations with periods @xmath119 and the revival time will thus be given by @xmath120 this estimate requires a numerical diagonalisation but gives a clear physical interpretation to the revival time observed in a specific realisation with @xmath42 atoms on @xmath7 lattice sites .
thus , taking and together , we have an understanding of the general physical mechanism triggering the collapse and revival of the resonant two - band oscillations .
we compare our prediction for the revival time , and , to actual numerical simulations in .
we find that gives the right order of magnitude for the revival in a specific realisation , and , in particular , it shows the correct scaling behaviour with the depth of the optical lattice ( shown in the inset of ) .
additionally , shows that the corrections for specific sizes of the system are well accounted for by , which only slightly underestimate the revival times by a few percent .
this deviation could be corrected by including more than three participating states , extending in this manner the arguments which lead to .
+ in an experimental realisation , the shorter the collapse time @xmath78 the easier it could be observed , and for an estimate we make use of the fact @xcite that the collapse time is proportional to the revival time @xmath121 where @xmath122 denotes the width of the distribution of coefficients @xmath109 necessary to expand the initial state in the eigenbasis . for the specific example of @xmath123 and @xmath124
we find @xmath125 for the width of the distribution ( i.e. the @xmath126 couplings include just one or very few additional states as in the derivation of above ) , such that we estimate @xmath127 compared to @xmath128 found numerically . in this work ,
we focused on realisations with ultra - cold atoms in a tilted periodic potential , and the observed effect can be manipulated by engineering the potential @xcite or the two - body interaction @xcite .
specifically , the revival time depends sensitively on parameters as the hopping strength and the external force close to the zeros of the bessel function in .
this is analogous to already realised manipulations by time - dependent forces as predicted by @xcite and realized in @xcite .
the observation of bloch oscillations over thousands of periods and a fine control on the two - body interaction have already been demonstrated experimentally @xcite .
therefore , the collapse and revival of resonant inter - band oscillations predicted here should be accessible in such state - of - the - art experiments .
we finally remark that the collapse and revival phenomena discussed in this section have their origin ( cf . ) in the degradation ( due to interactions ) of single particle _
inter - band _ oscillations .
so , even if there are analogies to the collapses and revivals observed in other experiments @xcite , the collapse - revival oscillations reported there arise from the interaction within a single - band .
therefore , in contrast to our results , those oscillations would not at all occur when the lower band interaction is suppressed , equivalent to @xmath129 in the model here discussed .
_ summary .
_ we studied the coupling between two energy bands in a two - band bose hubbard model with an additional tilting force .
the force can lead to a strong coupling of the bands and we found strong resonances in the inter - band oscillations in this lattice model .
furthermore , the two - particle interaction leads to a collapse and revival of the resonant inter - band oscillations . here , we made predictions for the relevant time scales which were verified numerically .
+ a closed two - band system is an idealisation , but it can approximately be realised in various parameter regimes with ultra - cold atoms @xcite using different techniques as e.g. super lattices @xcite .
in addition , the use of feshbach resonances allows a complete control and fine tuning of the interaction strength @xcite needed to test our predictions .
our work is a first important step in going beyond ground - band physics and accessing more degrees of freedom in bosonic ultra - cold gases .

– In a sign that the "billion dollar divorce" saga might actually be over before the only billionaires involved are lawyers, the Oklahoma Supreme Court has ruled against Sue Ann Hamm, the ex-wife of oil tycoon Harold Hamm. In a 7-2 decision, the court decided that since Sue Ann Hamm cashed a $974 million check from her ex-husband earlier this year, she no longer had the right to appeal the settlement, NBC News reports. Sue Ann Hamm, who was married to Harold for more than 20 years, was seeking a bigger slice of an estimated $18 billion fortune, reports the AP. The court ruled that Harold can still appeal the settlement, which also awarded Sue Ann three of their homes, if he chooses. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | One chapter in the "billion dollar divorce" has ended, and Oklahoma oil tycoon Harold Hamm has won, if you can call paying one of the largest divorce settlements ever a victory.

– Minecraft gamers kicked into real-life survival mode on Sunday when a fellow player who IDed himself as a teen "crippled" by depression and social anxiety posted desperate messages on Reddit. NotARomanGuy, who plays Minecraft using the CaesarOctavius handle, posted two notes to Reddit Sunday. One posted on r/UltraHardcore began "tonight, I am taking my life." In that post and the second, he relayed his eight-year struggle with depression and called himself "an unliked outcast at school," "unloved in my family and not appreciated in any other groups," "inadequate and meaningless, hated and worthless." He added, "Even my mother told me she doesn't want me in her life" and said, "I just want to know what it's like to be appreciated. To be liked. To be loved." The Reddit community gave him the chance to experience those feelings by rallying to his support on both the SuicideWatch and UltraHardcore subreddits, offering words of encouragement and imploring him to seek help. One user created a Minecraft homage to NotARomanGuy's avatar, while more than 50 others joined a voice conference to talk him out of it, according to Mashable. The next day, he expressed his gratitude in a couple of follow-up Reddit posts: In one he mentions his "extremely tough" night, adding, "Thanks for all the support; it was overwhelming and it saved my life. I love you all." Meanwhile, in his second online "thank you," he assures other posters he'll be consulting with a school counselor about selecting a psychiatrist and tells others to "ask people how they're doing before it's too late, because it was almost too late for me. Everyone fights their own battles." Read his heartfelt messages in their entirety here and here.

dipole , triangular , and higher harmonic flow that have an origin in the initial density fluctuations has gained a lot of attention as they can provide additional important information about the dynamical properties ( e.g. viscosity ) of the system .
the fluctuations in the initial geometry should be also reflected in the detail shape and velocity field of the system at freeze - out . in this
talk i discuss the possibility to measure such fluctuations by means of identical and non - identical particle interferometry .
the initial spatial conditions in heavy ion collisions are not azimuthally symmetric .
due to particle rescatterings it leads to the anisotropic flow
anisotropies in particle momentum distributions with elliptic flow being the well known example .
recently , a significant progress has been reached in understanding the role of the initial density fluctuations .
in particular it was realized that such fluctuations lead to odd harmonic anisotropic flow , studying of which brings new insights into dynamics of the system evolution .
below , i briefly summarize recent developments .
i apologize for not providing the full list of references many of which can be found in other proceedings of this conference . an importance of the initial state fluctuations for flow development has been noticed in @xcite , though the exact relation between fluctuation and the final event anisotropies were not clear . in
@xcite an observation was made that non - zero two - particle rapidity correlations ( as observed in @xmath0 collisions ) in conjunction with radial flow ( accepted part of the system evolution in @xmath1 collisions ) lead to a narrow in azimuth and long ranged in rapidity correlations .
such correlations were observed experimentally and called _
ridge_. this mechanism ( non - zero `` primordial '' rapidity correlations + radial flow @xmath2 ridge ) have been exploited later in several other models that try to address in more detail a ( more subtle ) question of the origin of the `` primordial '' rapidity correlations .
although the appearance of the ridge and anisotropic flow fluctuations look as totally unrelated phenomena , they appeared to be different views on the same thing
reaction of the system to the fluctuation in the initial density . in
@xcite it was shown explicitly that the fluctuations in the initial density distribution that extends over large rapidity range lead to the ridge structure in two particle correlations .
it was also noticed that after subtraction of the expected contribution from elliptic flow , two - bump structure appears on the away - side .
further studies @xcite with a single hot spot
embedded into otherwise smooth background appeared quite revealing .
contrary to an expectation @xcite that such a hot spot moved out by the radial flow would create a `` bump '' in azimuthal distribution it appeared that that the hot spot actually `` blocks '' the development of the radial flow and leads to a `` dip '' in particle distribution at the corresponding azimuth , accompanied by side - splashes from both sides .
remarkably , in terms of the correlation function the `` bump '' and the `` dip '' leads to the same structure - the ridge , as both means _ positive _ correlations . at the same time , the exact shape of the correlation function ( e.g. the strength of the third harmonic , which is important below ) is different .
it was noticed in @xcite that the fluctuating initial conditions generate anisotropic flow of different harmonics . that followed by understanding @xcite that the perturbations due to each of the hot spots can be treated independently , which allows to reformulate the problem from a different perspective
decompose the initial density into multipoles and study the system responce to each of the multipoles - the approach widely discussed at this conference as flow ( dipole , triangular , quadrangular , etc . )
fluctuations .
one can envision such an approach as rotating each of the event to a given harmonic symmetry plane , such that at the end one could have a smooth initial conditions but with a shape corresponding to a given harmonic .
the question addressed in this talk is if with the help of femtoscopy ( identical and non - identical two - particle correlations ) one can directly observe such triangular etc .
shapes of the system . in this study
i follow an approach of the first papers where the azimuthally sensitive femtoscopic analyses have been proposed @xcite , and blast wave and ampt models calculations . for typical values of parameters used in this work . ,
title="fig:",width=207 ] for typical values of parameters used in this work .
, title="fig:",width=192 ] for typical values of parameters used in this work .
, title="fig:",width=226 ] intensity interferometry ( identical particle femtoscopy ) , measures particle space - time distribution at freeze - out . due to the probe on - mass constraint
, the full space - time information can not be obtained , and one can access only the distribution in @xmath3 , where @xmath4 is the particle position at time @xmath5 ( after freeze - out ) , and @xmath6 is the particle velocity . for a gaussian source , the correlation function appears to be a gaussian c ( , ) 1 + _ i , j r_ij^2 q_i q_j , where @xmath7 is the pair relative momentum , @xmath8 is the particle average momentum , and @xmath9 are the hbt radii .
the deviation from a gaussian form can be studied by evaluating the higher moments of the distribution ( for the effect of non - gaussiness on hbt radii , see @xcite ) .
detailes of femtoscopic analyses can be found in a review @xcite .
we use a standard side - out - long system @xcite ( see figure [ fig : coordinates ] ) and concentrate on azimuthal dependence of the side , out , and side - out radii . for a _ stationary _ ( not expanding ) source
the radii azimuthal dependence can be expressed as r_side^2= = ^2+^2 - 2 , which has only @xmath10 harmonic .
higher harmonics azimuthal dependence appears only as deviation from the gaussian , e.g. in @xmath11 and @xmath12 for triangular and quadrangular shapes respectively .
the picture changes if one considers azimuthal variation in the expansion velocity . to study this effect
we employ a blast wave model .
we assume longitudinally boost invariant source and freeze - out at a constant temperature @xmath13 mev .
expansion velocity profile is parametrized in a form _ t(r,)=_t , max[1+a_boost ( n ) ] , + r_max = r[1+a_space ( n ) ] , with direction of the collective velocity being perpendicular to the line @xmath14 $ ] going through the emission point .
the parameter @xmath15 which corresponds to an average expansion velocity @xmath16 and @xmath17 gev . @xmath18 and @xmath19 parameters define the spatial eccentricity at freeze - out and modulation in the expansion velocity . for the first we assume that the system spatial eccentricity is reduced about two times during the system evolution , which leads to @xmath20
; @xmath19 can be estimated from @xmath21 dependence and is taken to be in the range 0.03 - 0.07 .
the azimuthal dependence of the obtained hbt radii , see figure [ fig : bwradii ] , indicates that the higher harmonics shape effects become clearly visible ( and measurable ) .
note the difference in the amplitudes of @xmath22 terms .
the radii modulation strongly depends on the parameters of the model , and the correspondng measurements will be very important in evaluating the velocity profiles at freeze - out and testing models . the ampt model @xcite has been extensively used in studying the effect of the initial state fluctuations .
we use this model to study au+au collisions at = 200 gev .
figure [ fig : amptradii ] shows the hbt radii variation as function of the azimuth relative to a given harmonic _
event plane _ which includes the effects of finite reaction plane resolution .
once again , the radii dependence on the azimuth is clearly seen . a detailed investigation of the side - out relative phases , dependece on the particle transverse momentum , etc .
requires additional investigations . , at @xmath23 .

– A woman hospitalized after she was hit by a falling tree while protecting her three young sons is suing New York City and the Central Park Conservancy for $200 million, WABC reports. According to ABC News, 39-year-old Anne Monoky Goldman was pushing two of her children, ages 4 and 2, in a stroller while her 41-day-old infant was strapped to her chest Aug. 15 in Central Park when a 75-foot-tall elm tree fell on them. Monoky Goldman was pinned under the tree for 10 minutes or so before being rescued. "They had to go take her out with chainsaws," a witness told the New York Daily News at the time. Her lawyers say she suffered spine and neck injuries and a concussion. Her 2-year-old son was treated for a brain hemorrhage and concussion. In the lawsuit filed this week, lawyers claim the tree fell because it was decayed underground, posed a danger to all park visitors, and hadn't been properly maintained or inspected. Monoky Goldman was released from the hospital last week, but her lawyers say she has to lay flat in bed for the next two to three months while her neck fractures heal. They say she may not be able to walk again. "She can't pick up her baby, she can't breast-feed, she can't do her job" doing social media for Tory Burch, one attorney tells the Daily News. The city is reviewing the lawsuit.

– It's a crime of some passion in Syracuse, just down the road from the birthplace of the Buffalo chicken wing: Father and son Paul Rojek and Joshua Rojek stand accused of pilfering a squawk-worthy $41,000 worth of wings from the restaurant where they worked, and as the Post-Standard reports, they apparently managed to do it in a 10-month spree that ended in late November with criminal charges. Police say the Rojeks billed the wings to the business account of the Twin Trees Two Restaurant, picked them up from the supplier, then sold them on the street and on the side to other restaurants at slashed prices, pocketing the proceeds. They're charged with third-degree grand larceny and first-degree falsifying business records. It's allegedly not the first time they pulled the caper, reports CNYCentral: They were charged last year with stealing chicken wings from another restaurant. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | SYRACUSE, NY -- Two employees of a Syracuse restaurant are accused of stealing more than $40,000 in chicken wings and selling them to other restaurants and "on the street" for a poultry sum, according to the Onondaga County Sheriff's Office. Sheriff's office spokesman Jon Seeber said Paul Rojek, 56, and Joshua Rojek, 33, of Syracuse, billed approximately $41,000 of chicken-wing orders to the Twin Trees Two restaurant's business account between February and late November. The father-son pair was employed there as cooks, Seeber said. The pair would pick up the orders and re-sell them on the street or to other local establishments for a reduced price. They would later destroy and withhold the sales transactions receipts for those orders, Seeber said. They're facing charges including grand larceny in the third degree and falsifying business records in the first degree. They appeared in court Nov. 24 where a judge set their bail at $2,500 cash or bond. ||||| SYRACUSE, N.Y. -- A father and son found themselves in hot water after police busted their chicken wing racket last month, according to the Onondaga County Sheriff's Office. Police say 56-year-old Paul Rojek and 33-year-old Joshua Rojek started the racket while they were employed as cooks at Twin Trees Too Restaurant on Milton Avenue. The duo allegedly developed a system where they would order chicken wings from the restaurant's supplier, pick up the orders and re-sell the chicken on the street or to other local businesses for a reduced price, according to police. From February to November, the father and son were able to hide $41,000 worth of product. Both men are charged with third-degree grand larceny and first-degree falsifying business records. This is not the first time the father has been arrested for this same crime -- According to the Onondaga County Sheriffs' Office, he was arrested for allegedly stealing chicken wings from Dominick's restaurant in 2014. |

– If the public sector won't have him, Mitt Romney is fine returning to the private one: He is taking a new post with son Tagg's venture capital firm, reports NBC News. Romney will serve as chair of Solamere Capital's executive committee, which translates into about a week of work per month advising on private-equity decisions. Letters have gone out to top investors, reports AP, which notes that Romney already was a limited partner at the Boston company. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Mitt Romney has a new position with his son's Boston-area venture capital firm. Last year's Republican presidential nominee will serve as chairman of the executive committee for Solamere Capital. The firm was founded by Romney's oldest son, Tagg, and the national finance committee chairman for his presidential campaign, Spencer Zwick. Romney has been a limited partner in Solamere, and investors have been sent letters announcing his elevated role. The Associated Press obtained a copy of one of the letters on Wednesday. Romney has just begun to emerge from months of isolation at his home in southern California. In a Sunday television interview, he said "it kills me" to have lost the presidential race. He delivers his first public speech since the loss next week in Washington. ||||| Former Massachusetts governor and GOP presidential nominee Mitt Romney will be working at his son Tagg's investment firm, Solamere Capital, for one week a month. NBC's Brian Williams reports. Former Massachusetts governor and Republican presidential nominee Mitt Romney has a new job. NBC News has learned that Romney is returning to the private sector, joining his eldest son Tagg's investment firm, Solamere Capital, as chairman of the executive committee. A person with knowledge of the deal tells NBC that Romney is planning to work with Solamere for one week a month. He will be advising on matters of private equity, and is not planning to fundraise at all for the firm. An email is expected to go out tomorrow heralding the news to top investors. Romney has held office space at Solamere, which is based in Boston, since the election. However, he has mostly spent time with his family since the loss, and has not been officially involved in business matters. His campaigns for president in 2008 and 2012 largely focused on his background in the business world. Romney founded asset management company Bain Capital in 1984.

marijuana is one of the most frequently abused illicit substances in the world especially australia .
cannabinoid hyperemesis syndrome ( chs ) is characterized by a triad of symptoms : cyclic vomiting , chronic marijuana use , and compulsive bathing .
it involves recurrent episodes of self - limited nausea and vomiting lasting several days and patients are asymptomatic between episodes .
we believe that cannabinoid hyper emesis syndrome is much more common than currently recognized .
we present a unique case with an apparent positive family history of the same clinical entity . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | marijuana 's medicinal use as an anti - emetic and appetite stimulant , especially in patients receiving chemotherapy , is well established . the first published cases of chs were reported in 2004 although an earlier case was reported in 1996 ; however , the authors did not specify cannabis use as the cause . cannabis has an active compound -9-tetrahydrocannabinol ( thc ) which acts on presynaptic brain receptors cb1 and cb2 , whereas , inhibition of gastric motility by 9-thc is primarily due to activation of the cb1 receptor in the vagal circuitry of the brainstem . while the mechanism of this syndrome remains unknown , there are hypotheses which fall into two categories 1 ) dose dependent build - up of cannabinoid and related effects of cannabinoid toxicity and , 2 ) the functionality of cannabinoid receptors in the brain and , particularly , in the hypothalamus ( which regulates body temperature and the digestive system ) . the enteric effects of marijuana ( e.g. , decreased gastrointestinal motility ) are thought to override the brainstem - mediated antiemetic effects to promote emesis ; however , this does not fully explain antiemetic action of cannabis . it is also suggested that instead of 9-thc , other lipid - soluble components of marijuana such as non - intoxicating cannabinoid could induce vomiting , since high doses of this compound have been reported to cause emesis in the house musk shrew . the desire for hot showers is either to counteract the marijuana - induced decrease in core body temperature or is a direct response to cb1 receptor activation in the hypothalamus . considering the ambiguity of the role of marijuana in producing this syndrome , further research is warranted to enhance our understanding of the role of cannabinoids in gastric motility . considering the mass of case reports published so far and the possibility of familial effects , we wonder if it opens a portal for a new diagnosable entity . |

– President Obama is back in DC after a two-week Hawaii vacation, and one detail of how he spent his 15th day in paradise is grabbing a few headlines: In addition to beach time and a visit to the National Memorial Cemetery of the Pacific (his mother's father is buried there), Obama and his girls visited with Pearl Jam lead singer Eddie Vedder on Saturday afternoon. The Washington Post reports that Vedder lives part-time in the state, also likes Chicago sports, and has rubbed shoulders with Obama before: The musician performed at a fundraiser for Obama in Florida in 2012 and managed to get in a birther joke, quipping that the ukulele he was playing had its own "little birth certificate." | 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.

(AP Photo/Andre Penner) President Obama spent part of Saturday hanging out with Pearl Jam frontman Eddie Vedder. Obama and his daughters visited Vedder and his family, according to the White House. Vedder lives in Hawaii part-time and is an Obama supporter. He played a four-song set at a Florida fundraiser in 2012, trading in a mandolin for a Hawaiian ukulele. "It has a little birth certificate in there," Vedder joked. He recorded an album titled 'Ukulele Songs' in 2011. Vedder and Obama had another thing to talk about - they're both Chicago sports fans. But their politics have diverged at times. Vedder supported Green Party presidential candidate Ralph Nader in the 2000 presidential election. No word on what the two discussed or Obama's favorite Pearl Jam album. Our vote is for 'Ten.' Obama made a number of other stops during the final hours of his Hawaii vacation Saturday. Obama, Malia and Sasha spent about 20 minutes at the Honolulu home of his half sister, Maya Soetoro-Ng. . The president and his daughters also spent time at the Punchbowl Memorial Cemetery of the Pacific, where his maternal grandfather is buried. Obama and his family will return to Washington Sunday. |

– As doctors bring Joan Rivers out of a medically induced coma, there's some concern the comedian could end up "either a vegetable or in a wheelchair," the New York Daily News reports. That news has her family considering a lawsuit. Whether or not Rivers, 81, has suffered brain damage won't be evident until she wakes up, which could happen today; she's been on life support since Sunday. Rivers' condition—following cardiac and respiratory arrest during an outpatient, routine throat surgery last week—has left her daughter, Melissa, "totally hysterical," a source tells the Daily News. "Shock and upset is turning to anger, and they are looking for someone to blame," says the source. The legal threats are directed at Yorkville Endoscopy on the Upper East Side, which Rivers' family claims botched the surgery on her vocal cords Thursday, the Washington Times adds.

– The Air Force is cutting loose a staff sergeant who championed the debunked “birther” conspiracy theory online. Daryn Moran says he stopped reporting for duty at an Air Force base in Germany, arguing that his orders were invalid because Obama was an invalid president. “Now it’s plain and simple,” he tweeted Monday, according to the Omaha World Herald. “Arrest B. Obama, or arrest me.” But that was never going to happen, the Air Force Times reports, because he didn't actually go AWOL, as he claimed; Moran was already on approved leave. "He is currently outprocessing for discharge from the Air Force which was previously approved by his commander on August 4th," reads an Air Force statement. Moran’s birther antics weren’t the only thing that may have gotten him discharged; on Aug. 15 he wrote that mental health evaluators had recommended he be discharged “for a ‘personality disorder’” because he said homosexuality is a sin. A coworker had also complained after he asked a doctor in his unit about her Muslim faith—according to Politico, he’d made disparaging comments about Muslims, and Obama’s ties to the faith. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Web wide crawl with initial seedlist and crawler configuration from March 2011.

– Today's appearance by the NSA chief on Capitol Hill didn't produce many surprises—he said data mining is necessary and used in such a way that it doesn't invade privacy—but it did produce one strange moment featuring Sen. Barbara Mikulski. At one point, the Maryland Democrat paused the hearing to read a critical tweet from BuzzFeed reporter Rosie Gray—"@SenatorBarb is trying hard to keep the other senators from asking Gen. Alexander anymore about data mining programs.” Mikulski took exception, reports Politico. “Not everybody might be watching C-SPAN, so I want to say to Rosie and to others who might read it from Rosie: There is no attempt here to muzzle, stifle any senator from asking any line of questioning.” She also noted that the hearing was originally scheduled to talk about cybersecurity, not surveillance, "but any senator can ask any question at this hearing that they want to." Around that point, she smiled and picked up her smartphone. "So Rosie, it’s an open hearing. Hi. Look forward to keeping in touch.” (After which, Gray tweeted, "guess I should have subtweeted.") | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Who says senators aren’t tech-savvy?

Alexander anymore about data mining programs.” Text Size - + reset Mikulski, the chairwoman of the Senate Appropriations Committee, had National Security Agency head Keith Alexander as well as FBI and Homeland Security Department officials before her on the issue of cyber security. But the news cycle had most senators looking for Alexander to address revelations of broad phone recordkeeping and Internet surveillance by the NSA — so most senators took the opportunity to ask Alexander about the surveillance anyway, with Mikulski interrupting several such inquiries. (PHOTOS: Pols, pundits weigh in on NSA report) After catching a glimpse of Gray’s Twitter critique, Mikulski said, “Not everybody might be watching C-SPAN, so I want to say to Rosie and to others who might read it from Rosie: There is no attempt here to muzzle, stifle any senator from asking any line of questioning.” “We’re here on cyber, but any senator can ask any question at this hearing that they want to.

Dan Coats (R-Ind.) said Mikulski had been “extremely tolerant of our diversion” from the subject of cybersecurity. Mikulski had warned as the hearing began that NSA questions are for “another day”: Thursday, when all 100 members of the Senate will have the opportunity to meet with Alexander — behind closed doors. ||||| 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.

– Note to movie makers: Give the police a heads-up when filming a robbery scene in public. Newly released police bodycam video released by the city of Crawfordsville, Ind., shows how close one actor came to learning that lesson in the worst possible way. Officers responded to a robbery call at a local bar when someone spotted a masked gunman entering. Cops arrived just as actor Jim Duff was stepping back out, holding a fake gun, and an officer fired a shot when he didn't immediately drop his weapon as ordered, reports ABC 7. Luckily, the bullet didn't hit him. "We're doing a movie," Duff can be heard trying to explain as officers order him to get on the ground. Police ended up holding him in custody until they confirmed that he was, in fact, part of a movie being filmed. No charges will be filed related to the incident, reports the Journal & Courier.

The caller told dispatchers that a man in a ski mask entered the bar with a gun.Sgt. Matt Schroeter arrived at the location and saw a man in a ski mask backing out the door. He appeared to be holding a weapon. The "robber" was actually actor Jim Duff, who was filming a scene for a movie.But Schroeter didn't know that."Drop the gun! Drop the gun now!" Schroeter yells in body camera footage released after the incident. Duff then turns toward the officer and takes off his mask; Schroeter fires a shot and repeats his orders for Duff to drop his weapon."We're doing a movie," Duff says after taking off the ski mask and dropping the weapon.The officer then orders him to get on the ground. Duff complies and then yells to someone inside the bar, "You guys better get out here, man."Someone starts to come out the door, but the officer tells them to stay inside.Police said neither the production company nor the bar owners told them that a movie was being shot in the area. It didn't help that the other actors and filming equipment were inside the business, making it difficult to know that a movie was being shot.Duff was placed into custody until police could confirm that he was part of a movie scene."We could not see the police, so when the actor left the building we had no knowledge any police had even arrived at the scene," Montgomery County Movies owner Philip Demoret told CBS4.No charges were filed in connection with the case. Demoret said he planned to work with Crawfordsville police so that something like this doesn't happen again. |

– Jennifer and Sam share the same blood type and birth date, down to the year, but that's not what makes them a perfect match. In a video posted to YouTube by Jennifer's employer, HSBC Bank—pointed out by Mashable—the Taiwanese couple explain they make each other better people. Over 11 years together, Sam says Jennifer has made her "more positive," while Jennifer says Sam "gets me to explore the beauty of this world." That's why the two weren't willing to let Taiwanese law stop them from declaring their love for each other in a wedding ceremony on Nov. 13, just as Jennifer wasn't going to let her parents' objections keep her from walking down the aisle. Luckily, she wasn't alone. Though her parents no longer speak to her, "my boss and colleagues have been very supportive," says Jennifer. In fact, when she told HSBC's Taiwan CEO John Li that her dad wouldn't be there to walk her down the aisle, he offered to step in. He "told us not to be nervous and to walk slowly," she recalls. "We cried because we never thought we would make it this far." While same-sex marriage is not yet legal in Taiwan, Jennifer says a ceremonial wedding was better than "faking a marriage for my father's sake," something she previously considered. Still, she hopes to one day make her father proud. For now, though, the couple have one goal: to "create respect among different communities." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Being gay can be especially tough in some conservative Asian cultures, but supportive workplaces can make all the difference. This video posted by HSBC Bank in Taiwan tells the story of one of its employees, Jennifer. In an interview segment in the video, she reveals that her parents don't acknowledge her relationship with her partner, and refused to attend their wedding. So the bank's country CEO, John Li, walked her down the aisle on her big day. The touching video also talks about Jennifer's 11-year relationship with her partner, Sam. Image: hsbc now/youtube "My parents are strongly against it," says Jennifer. "Whenever my father sees Sam, he will push her out and tell her to get lost." Jennifer adds that her biggest worry about coming out was that it would affect her work. "I was concerned that it would stop clients banking with [us]. So I considered it very carefully," she says. However, her colleagues have come out in full support of her. Image: HSBC NOW/YOUTUBE "CEO John was willing to walk me down the aisle, [he even] told us not to be nervous and to walk slowly," she says. Taiwan has not legalised same-sex marriages, so the couple's wedding is ceremonial. But Jennifer notes that she hopes her story will encourage others LGBTQ couples facing the same pressures. "This wedding is really for the LGBTQ community," says Jennifer. "We hope our actions will encourage people and create respect among different communities." This is not the first time HSBC has made a big show of support for LGBTQ couples. Earlier last year, it unveiled a pair of rainbow lions in front of its Hong Kong office as part of its "Celebrate Pride, Celebrate Unity" campaign. "This campaign demonstrates our commitment to achieving a truly open and diverse working environment," said HSBC Group general Kevin Martin in a statement. ||||| Go to the Legal Help page to request content changes for legal reasons. |

– A French tourist is being praised for saving a busload of fellow passengers from "catastrophe" after the driver passed out. The bus was on a winding road in the Austrian Alps near Schwaz when the 76-year-old driver collapsed, the BBC reports. As the bus was careening toward a precipice, a 65-year-old man sitting near the front jumped from his seat and managed to hit the brakes at the last second, per Le Quotidien. The bus slammed into a wooden barrier, preventing it from hurtling down a slope and over a 328-foot cliff. LQ published a photo of the bus, its front end punctured by the barrier, tilting down a grassy hill. A local police rep praised the hero passenger's quick reflexes.

– House Republicans won't take up immigration reform after all, because there's "widespread doubt" about whether President Obama can be trusted to enforce anything they pass, John Boehner said today. "The president seems to change the health-care law on a whim," Boehner said, according to the Wall Street Journal. "Now he's running around the country telling everyone he'll keep acting on his own." Boehner suggested that Obama push Senate Democrats to take up House-passed job legislation as a trust-building measure, Politico reports. The comments are widely being viewed as a stake through the heart of immigration reform hopes, because Boehner is seen as immigration's biggest fan amongst the GOP leadership. Yesterday Mitch McConnell said reform was likely impossible, because the Senate insists on a comprehensive bill, and the House insists on piece-meal efforts, CNN reports. "I think we have an irresolvable conflict here," the Senate minority leader said. Many Republicans also worry that passing anything would be seen as a Democratic victory going into the midterms. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | House Speaker John Boehner squashed growing expectations that Congress would rewrite immigration laws this year—dealing a setback to the White House, a swath of U.S. businesses and a bloc of fellow Republicans seeking to improve their party's chances with Hispanic voters. Rank-and-file Republicans have voiced few complaints about the GOP's latest ideas for an immigration overhaul, which include some legal status for most of the 11.5 million people in the U.S. illegally. But many balked at debating an issue that divides... ||||| 4 years ago (CNN) - Senate Minority Leader Mitch McConnell said Tuesday he can't see an agreement on immigration reform happening this year, citing an "irresolvable conflict" between the U.S. Senate and House. McConnell indicated the Democratic-controlled Senate's insistence on comprehensive legislation is at impossible odds with the House Republican majority's preferred piecemeal approach to immigration reform. Follow @politicalticker "I think we have an irresolvable conflict here. The Senate insists on comprehensive. The House says it won't go to conference with the Senate on comprehensive and wants to look at step-by-step," he told reporters after a meeting with the Senate Republican conference. "I don't see how you get to an outcome this year with the two bodies in such a place." House Republicans laid out last week a blueprint of immigration "standards," saying there "will be no special path to citizenship" for the country's estimated 11 million undocumented immigrants. The GOP principles call instead for a path to legalization, and only after those already in the country illegally get in the back of the line and the federal government continues to bolster border security. The Kentucky Republican did not take a position on the GOP outline. The Senate passed a comprehensive bill that included a path to citizenship last year, but the House has not taken up the measure. The White House has said it's open to the House approach but the President warned in an interview with CNN's Jake Tapper against reform that creates "two classes of people" in the country. |

– A North Carolina woman who seemingly vanished in 2011 has been found safe and living under a false name in Columbus, Ohio, police say. Rachel Natacha Owens was just 15 when she was last spotted getting off a school bus and into a vehicle in the parking lot of South Brunswick High School in Boiling Spring Lakes, reports the Wilmington Star News. The teen had previously run away for brief periods, per the New York Daily News, and for five years, Owens' parents and five siblings didn't hear a word from her. In 2014, however, FBI agents say they received a tip that Owens might be in Columbus—which is exactly where she was found around noon Friday, according to the Brunswick County Sheriff's Office. The 21-year-old—previously believed to be with a much older man, per the Star News—had left North Carolina of her own accord and "went to great lengths to intentionally conceal her whereabouts, even assuming a false identity and date of birth," police say in a release. "There is no foul play in Rachel’s disappearance and no charges will be pursued at this time." In that respect, it's a happy ending because "some people assumed you are never going to find her because ... you're chasing a ghost," FBI Special Agent Rich Novelli says. "Thankfully none of us gave up." It isn't clear if a reunion is expected. (Police have a new lead in a 47-year-old disappearance.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | A North Carolina woman who went missing as a teenager five years ago is reportedly alive and well and living in Columbus, Ohio. Rachel Natacha Owens had not reached out to her parents or her five siblings since her May 5, 2011 disappearance. Reports say it was her intention to remain undetected. Owens was 15 years old the last time residents of Boiling Spring Lakes saw her. The small town girl was recognized getting off a South Brunswick High School bus and getting into an unidentified vehicle, according to footage recovered by police. The FBI released a missing persons report on the teen, offering a $5,000 reward for information leading to her return. The report admitted it wasn’t the first time the teenager had run away. Two Texas teens found a day after they went missing Rachel Natacha Owens disappeared when she was 15 years old. (FBI) Owens, now 21, is said to have gone to “great lengths” to hide her whereabouts. She had even assumed a false identity and date of birth when found by police. The Sheriff’s Office released a press statement on Friday announcing, “There is no foul play in Rachel’s disappearance.” “No charges will be pursued, at this time,” a spokeswoman from the department wrote. In a press conference the day before Father’s Day in 2014, Brunswick County Sheriff's Office Sgt. Candi West spoke on behalf of Rachel’s parents, Kenneth and Kathy Owens. “If Rachel sees this or someone that is associated with Rachel sees this — her family just wants to know that she’s okay, her family just wants her to know that they miss her and they love her,” West said.

– A Vermont librarian who sued consumer credit bureau giant Equifax following a massive 2017 breach of private data has been awarded $600. The largely symbolic suit by Jessamyn West was her way of showing people they have the power to arm themselves in the fight for data security, even when companies like Equifax and others go largely unpunished. In an interview with KrebsOnSecurity, West said she hoped her decision to take direct action against the company as an individual would inspire others to do the same. "A lot of people don’t feel they have agency around privacy and technology in general," West told the site. "This case was about having your own agency when companies don’t behave how they’re supposed to." West originally filed the suit in small claims court for $5,000, where she argued that the widely publicized September breach was an undue burden on her as she struggled to deal with her personal data security and that of her recently deceased mother. A judge instead awarded her $690, with the $90 going to court costs and the rest recognizing the cost of two years of identity theft protection. As the Daily Dot notes, the judgment isn't much for a giant corporation like Equifax, but lots of little suits could add up. In fact, one claimant wrote back in January about receiving $8,000 in a similar suit against Equifax. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | BTW Equifax seems to have suffered very little in the wake of its massive 2017 data breach, which compromised the personal data of 143 million people. While many simply checked if there data was included in the breach and angrily went on there way, one Vermont librarian decided to take action—she sued Equifax, and won. Unfortunately, the victory was more symbolic than a deep-pocketed punishment that Equifax would feel to the core, but a victory is a victory nonetheless, and it could inspire others to follow suit. Jessamyn West, a 49-year-old librarian, sued Equifax in small claims court for the undue burden it put on herself and her family. West’s mother died in July, and she was in the process of settling her finances. The breach “added to the work of sorting out her mom’s finances while trying to respond to having the entire family’s credit files potentially exposed to hackers and identity thieves,” according to Krebs on Security. West sued for $5,000 in damages, but the judge ruled to only award her $690—$600, plus $90 to cover court fees. The $600 sum was awarded in order to cover the cost of identity theft protection services for two years. West’s goal wasn’t to make a large sum off of Equifax, which still reported $3.4 billion in revenue last year despite its enormous data breach, but rather to draw continued awareness about privacy and technology. “This case was about having your own agency when companies don’t behave how they’re supposed to with our private information,” West said. Following news of the data breach, one Stanford student developed a bot to help victims file suits in small claims court. Others who’ve filed suits have been awarded up to $8,000. While West—and others’—sum from her case is small, if millions of others who suffered in the aftermath of the data breach decided to file claims, Equifax could finally feel the impact of its negligence.

– Ever wonder why it doesn't take elephants an hour to pee? Well someone did. After studying mammals of all walks of life at Zoo Atlanta, scientists discovered that, aside from those that weigh 6.5 pounds or less, it takes the rest of us mammals on average 21 seconds to pee, give or take 13 seconds, reports Scientific American. Doesn't matter if it's a newborn human, a gorilla, or a giraffe; urination time is extremely consistent, something fairly remarkable when you consider an elephant's bladder is almost 3,600 times bigger than that of a cat. The reason, they surmise, is that even though bigger mammals tend to have bigger bladders, their urethra is wider and also longer, and thus—thanks to gravity—the flow is faster. David Hu, the mechanical engineer who filmed the mammals at the zoo, tells the LA Times he got the idea a few years ago when he was changing his young kids' diapers and thought, "How could anything be worse right now?" Which was immediately followed by: "Well, maybe if I was changing an elephant’s diaper." After hours spent at the zoo (during which they collected urine in cut-up soda bottles during the act in order to measure flow rate), the researchers also learned that smaller animals, like rats, don't pee in a jet stream but rather in little "gumballs" of water dispensed one at a time; they lack the amount of liquid needed to create a real flow. It seems that 6.5 pounds is the tipping point, which is why a grown bear takes as long to pee as sweet little Toto. Hu notes that the study could have health implications for humans: If one's urination duration falls outside the norm, it could signal a medical problem. (Speaking of Toto, dogs appear to use Earth's magnetic field to poop.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | In the time it takes you to listen to this story, an elephant could empty its bladder about three times. And, despite being much smaller, so could an adult cat. And a goat. Also a cow. Because researchers find that all mammals that weigh more than six-and-a-half pounds or so take about the same time to pee: 21 seconds, plus or minus 13 seconds. The researchers videoed various mammals urinating at Zoo Atlanta. And they found that, once you get above the squirrel-mouse-shrew level, tinkle-time does not scale with body size. Good news for elephants, who could otherwise spend all day going number one. Seems that larger animals have a longer urethra, the conduit that whisks the wee-wee away. That difference in size is big enough that gravity starts to really weigh in. As a result, when Jumbo answers nature’s call he has a much faster flow than does Mittens. Given the urethra’s structure, the researchers say that the mammalian urinary system can be “scaled up by a factor of 3,600 in volume without compromising its function.” The study is in the Proceedings of the National Academy of Sciences. [Patricia J. Yang et al, Duration of urination does not change with body size, preprint] This hydrodynamic finding could help engineers design systems that rapidly drain reservoirs, regardless of size. It also means if Mittens and Jumbo hit the head together, they can come out at the same time. —Karen Hopkin [The above text is a transcript of this podcast.] ||||| While timing each pee session was easy, measuring the flow rate was hard, because they had to collect the urine. That's no easy task. First off, it's hard to catch an animal in the act. Second, you have to catch all the urine in order to get an accurate measurement of how much liquid is coming out per second. And you have to do it by hand. It was unavoidable: The high-speed camera was occasionally splattered by urine, Hu said. |

– When a 2-year-old wants to find her mom and dad, a little wet concrete isn't going to stand in her way. And that's why little Izzadora Millaway of Cleveland, Tenn., is enjoying some viral fame, reports UPI. It seems that workers had just poured concrete in the basement when Izzadora, thinking her parents were down there, headed down to find them. As it turns out, her parents were with workers from Porter Concrete Construction, looking at the finished work from the outside of the house.

This little girl was trying to go see her mom and dad, so she came from upstairs to the basement to find them." Sara Millaway, the girl's mother, said she and her husband were with Porter workers looking at their work from outside when the toddler walked down the steps into the basement and trudged across the wet concrete. Millaway said she briefly considered leaving the footprints as a memento of Izzadora's amusing misadventure, but she decided instead to do a pair of "official keepsake" footprints on the still-wet floor. ||||| See more of Porter Concrete Construction Co. on Facebook ||||| A 2-year-old girl in Cleveland looking for her parents wound up leaving her mark - in a lot of places - in a basement that was being resurfaced on Friday. Workers for Porter Concrete Construction were on the job, and were outside with Izzadora Millaway's folks, taking a look from that perspective. But Izzadora didn't realize that. Her mom, Sara Millaway, says she went downstairs and walked through the wet cement to find mom and dad. Millaway says everyone thought it was hilarious. She says Izzadora is not in trouble, considering she just made a memory they'll all laugh about for years. Asked if she considered preserving the unintended footprints for all time on the basement floor, Millaway says they considered doing that, but decided instead to do a pair of "official keepsake" footprints from Izzadora before the cement dries. |

– Hulk Hogan, with funding from frequent Gawker target Peter Thiel, helped bring the media group to bankruptcy via his sex-tape lawsuit, so Thiel's choice of costume at a posh Long Island party might not be terribly surprising: He reportedly dressed as the Hulkster on Saturday night, when the PayPal founder attended a costume party thrown by Donald Trump donor Robert Mercer. The event was also attended by Trump himself and campaign manager Kellyanne Conway, who was "decked out as Dolly Parton meets Superwoman," per Vanity Fair. "Honoring the ultimate hero at the Mercer 'Heroes and Villians' party on Long Island. Crowd thrilled w/ surprise!" Conway tweeted, showing a photo of her and her boss, disguised as … himself, apparently, in a suit and tie. No pictures of Thiel's costume have popped up yet; the intel comes via two party guests who tell Bloomberg they saw him in his Hogan getup.

Naturally, Trump came dressed as himself. Former Trump campaign manager Kellyanne Conway showed up, too, decked out as Dolly Parton meets Superwoman. Onetime leader of the U.K.’s pro-Brexit Independence Party Nigel Farage—who has gotten closer to Trump since the election—was nattily attired as the naval hero Admiral Lord Nelson. Some costumes were more on the nose than others. Not one to be outdone, libertarian tech billionaire and Trump surrogate Peter Thiel reportedly arrived dressed as Hulk Hogan, the former wrestler whose invasion-of-privacy lawsuit against Gawker Media, which Thiel clandestinely funded, ultimately bankrupted the company earlier this year, fulfilling Thiel’s nearly decade-long personal vendetta against Gawker. (Unfortunately, no pictures of Thiel in costume have yet publicly surfaced.) Ever a contrarian, Thiel raised eyebrows in Silicon Valley earlier this year when he became a California delegate for Trump, delivering a prime-time speech on the Republican nominee’s behalf at the G.O.P. convention. Thiel also donated $1.25 million to Trump’s presidential campaign, forcing both start-up accelerator Y Combinator and Facebook to defend their corporate relationships with him, and turning Thiel into something of a pariah in the otherwise-liberal Bay Area. In October, Thiel defended both his financial contribution to the Trump campaign and his decision to bankroll Hogan’s lawsuit. “If you’re a single-digit millionaire like Hulk Hogan you have no effective access to our legal system,” he said, without a hint of irony. |

– At 6:28pm Eastern time tonight, an aircraft carrier-sized asteroid will swing by Earth at a distance of 201,000 miles, which is within the moon’s orbit. That’s the closest an asteroid has come to the planet since 1976, but don’t worry: NASA has determined the space rock poses no threat, the Wall Street Journal reports. You won’t be able to view it with the naked eye, but if you have a good sky chart and a 6-inch or larger telescope, you may have a shot, the Telegraph adds. The 1,300-foot-wide 2005 YU55 is traveling at 29,000 miles per hour. Researchers have been monitoring it, and will learn more about it through radar images. Asteroids are among the solar system’s oldest objects, and astronomers hope to glean clues about the origins of life on our planet. “This is an extraordinary opportunity to look at an extremely important type of asteroid,” says one NASA scientist. “A small army of astronomers are pretty excited about it.” Click for more on the asteroid. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Dow Jones Reprints: This copy is for your personal, non-commercial use only.

The 1,300-foot-wide asteroid, known as 2005 YU55, poses no hazard, experts at NASA's Jet Propulsion Laboratory said. They are monitoring the spinning space rock by radar as it nears and eventually speeds past Earth at a distance of 201,000 miles.

They are using the close encounter to learn more about the space rock known as 2005 YU55. The last time a cosmic interloper this size came this close to Earth was in 1976 and it will not happen again until 2028. Since late last week, antennas at the space agency's Deep Space Network in California have been monitoring the quarter-mile-wide asteroid as it approaches from the direction of the sun. The Arecibo Observatory in Puerto Rico planned a viewing Tuesday when the asteroid is set to make its closest pass at a distance of 202,000 miles at 11.28pm GMT. Since its discovery six years ago by a University of Arizona astronomer, scientists have learned a great deal about 2005 YU55. Its surface is coal black, and it spins slowly through space. Amateur skygazers who want a glimpse need two things: a good sky chart and a 6-inch telescope or larger since the asteroid is too faint to detect with the naked eye. Even with a telescope, sighting is not guaranteed. The glare from the moon may make the asteroid difficult to spot. |

* the ability to manipulate phonon waveforms in continuous media has attracted significant research interest and is crucial for practical applications ranging from biological imaging to material characterization . although several spatial focusing techniques have been developed , these systems require sophisticated artificial structures , which limit their practical applications . this is because the spatial control of acoustic phonon waves is not as straightforward as photonics so there is a strong demand for an alternative approach .
here we demonstrate a phononic time lens in a dispersive one - dimensional phononic crystal waveguide , which enables the temporal control of phonon wave propagation .
pulse focusing is realized at a desired time and position with chirped input pulses that agree perfectly with the theoretical prediction .
this technique can be applied to arbitrary systems and will offer both an improvement in time and spatial sensing resolution and allow the creation of a highly intense strain field , enabling the investigation of novel nonlinear phononic phenomena such as phononic solitons and rogue waves .
* acoustic phonons have been widely utilized in various applications and are especially important as a tool for nonintrusive sensing in such areas as biological imaging and defence systems@xcite .
the capabilities of these phonon systems , for example imaging resolution and accuracy , are determined by the spatial size and energy density of generated waves . to improve these capabilities ,
several spatial phonon focusing techniques have been proposed where engineered structures such as the phased arrays , negative - index materials and acoustic metamaterials enable acoustic phonons to be focused in tiny spatial regions@xcite .
however , these conventional focusing techniques , which use a spatial lens , rely on sophisticated spatially designed structures , and this limits their practical use .
a time lens , which is a temporal analogue to a spatial lens , has been introduced in the field of optics @xcite . according to space - time duality , which describes the mathematical equivalence between paraxial - beam diffraction and dispersive pulse broadening ,
the effect of dispersion in a medium is the key to realizing a time lens .
importantly , this temporal focusing method can be applied in an arbitrary dispersive material in which it imparts quadratic time - varying phase shift . on the basis of this concept ,
various useful ideas have been developed including temporal imaging , temporal magnification and real - time spectroscopy in optics @xcite . by introducing the approach in the field of phononics ,
we have realized a phononic time lens in a one - dimensional ( 1d ) phononic crystal waveguide ( pnc wg)@xcite which is constructed by nanoelectromechanical systems ( nems ) technology .
ultrasound phonon waves travelling through the wg experience pulse broadening due to the group velocity dispersion ( gvd ) effect .
this gvd effect can be used to compensate for the frequency modulation of the initial pulse that leads to temporal focusing . by further incorporating excellent mechanical properties of nems such as high - quality factors , integrability and nonlinearity into this device@xcite ,
the ability to temporally focus the travelling phonons will open up the possibility of developing an ultrashort and highly intense phonon pulse generator , which will be useful for practical applications as in the case of optical laser systems@xcite , and investigaing nonlinear phononic phenomena .
the pnc wg consists of a 1 mm long membrane made from a gaas / algaas heterostructure as shown in fig .
1(a ) , where periodically - arrayed air holes with a pitch of 8 @xmath0 m are formed along the wg that can be used to suspend the membrane with a width of 22 @xmath0 m by selectively etching the al@xmath1ga@xmath2as layer .
the application of an alternating voltage to an electrode located at both edges of the wg induces phonon vibrations due to the piezoelectric effect .
the resultant vibrations travel down the wg and are detected in an optical interferometer .
figure 1(b ) shows the experimental transmission spectrum of the device and the corresponding band structure calculated by using a finite element method ( fem ) simulation ( comsol multiphysics ) .
the phonon vibrations are observed in 3.5 - 7.5 mhz owing to the presence of 1st phonon band , where the phonon vibrations propagate in the wg and are reflected at both clamping edges thus resulting in the generation of equidistant fabry - perot peaks in the spectral response . on the other hand , phonon waves around 8 mhz experience bragg reflection from the periodic air holes , giving rise to a phonon bandgap , and
this prevents them from propagating in the wg@xcite . above the bandgap
, there is a new phonon branch that again allows the phonon vibrations to be guided . in the experiments described below , we focus on the 1st phonon branch to investigate the temporal dynamics of the phonon vibrations in the device .
a transverse deflection @xmath3 travelling in a 1d pnc wg can be described by euler - bernoulli equations as@xcite , @xmath4 where @xmath5 is the young s modulus , @xmath6 and @xmath7 are the area and moment of inertia of the cross section , @xmath8 is the density of the wg per unit length and @xmath9 and @xmath10 are the elastic coefficients of the wg . to solve equation ( [ eq : w ] )
, the slowly varying amplitude of travelling wave is assumed that the envelope of a travelling vibration pulse centred around wavenumber @xmath11 and angular frequency @xmath12 varies slowly in temporal and spatial domain on the moving - frame with group velocity , @xmath13 .
\label{eq : za}\ ] ] we introduce the linear loss term @xmath14 , then @xmath15 satisfies the following equation@xcite , @xmath16 where @xmath17 is the inverse of the group velocity , @xmath18 is the gvd coefficient and @xmath19 is a nonlinear parameter .
these terms are determined by the material and geometric parameters of the wg in equation ( [ eq : w ] ) .
thus , the dynamics of phonon propagation based on the euler - bernoulli equation corresponds to a nonlinear schr@xmath20dinger equation ( nlse ) , which is used to describe the dynamics of an optical wave propagating in a dispersive medium@xcite . by neglecting the nonlinear term in equation ( [ eq : aa ] ) and using the new time coordinate @xmath21 moving with the group velocity @xmath22 , @xmath23
at the same time we introduce a normalized amplitude @xmath24 , @xmath25 where @xmath26 is the peak amplitude of the input pulse , and the equation can be simplified as @xmath27 interestingly , equation ( [ eq : u ] ) is mathematically equal to the paraxial wave equation that governs the diffraction of cw light .
if we assume a gaussian pulse as an input , the normalized amplitude at distance @xmath28 is given by@xcite , @xmath29 where @xmath30 is the half - width at the 1/@xmath31-intensity point , and its output width @xmath32 is written as @xmath33 thus a phonon temporal waveform travelling down a dispersive medium depends on the absolute value of the gvd coefficient that enables the temporal pulse width to be broadened further due to the larger dispersion . to elucidate the temporal characteristics of this device experimentally ,
phonon vibrations are measured at the left edge by exciting them with a gaussian pulse with @xmath34s from the right edge as shown in fig .
2(a ) .
this time - of - flight measurement also enables the group velocity @xmath35 and the gvd coefficient @xmath36 to be estimated as function of excitation frequency as shown in figs .
2(b ) and 2(c ) respectively .
the experimental @xmath35 value increases with increasing frequency i.e. anomalous dispersion ( @xmath37 ) in the band except near the bandgap where there is a large reduction in @xmath35 , i.e. normal dispersion ( @xmath38 ) , because of the decreased slope of the band .
in addition , the temporal waveform of the pulse around the band edges is distorted and becomes asymmetric with an oscillation near the trailing edge caused by a contribution from the 3rd order dispersion effect ( see supplementary information for more detail ) .
these experimental results can be well reproduced by the calculation results obtained with fem - simulated band structures .
the temporal pulse widths can also be estimated from the time - of - flight measurement in fig .
2(a ) by fitting a gaussian envelope to the output waveforms .
figures 3(b ) and 3(c ) reveal the output pulse widths at various excitation frequencies when exciting gaussian pulses with @xmath39 and 0.7 @xmath0s respectively and measuring them at distances @xmath40 1 , 3 and 5 mm ( see fig .
3(a ) ) .
as theoretically predicted , the pulse widths are greatly increased as the frequency approaches the band edges where @xmath41 is large and the gvd - induced pulse broadening becomes distinct with increasing propagation distance as shown in figs .
3(b)and 3(c)@xcite .
in particular , shortening the input pulse from @xmath42 @xmath0s to 0.7 @xmath0s , namely spectrally broadening , leads to the significant influence of the propagation distance on the output width as shown in fig .
3(c ) . in the previous experiment we confirmed that the pulse is broadened during propagation thanks to the gvd effect . in an anomalous ( normal ) dispersion regime ,
the high - frequency components of the pulse travel faster ( slower ) than its low - frequency components , thus allowing the injected un - chirped pulse to be frequency chirped and broadened , where the product of the temporal and spectral widths is not transform limited . in general
, this effect is unfavorable for efficient phonon guiding .
however , we utilize the disadvantage to demonstrate temporal focusing , namely the compression and amplification , of the travelling phonon pulse . here
, a frequency - chirped pulse is excited as the input , and frequency modulation within the pulse is compensated for by the gvd via propagation , thus resulting in the pulse being compressed to the lower limit for the pulse width determined by a given spectrum , namely transform limited , and the peak amplitude being amplified .
thus this temporal analogue of a spatial lens , called a time lens , enables the temporal focusing of a phonon wave@xcite .
the dynamics of the chirped pulse evolution in the wg can also be described by nlse , and the output pulse width @xmath43 is given by @xmath44 @xmath45 is a chirp parameter that is positive ( negative ) when the frequency increases ( decreases ) linearly from the leading to the trailing edge , and is defined by @xmath46 where @xmath47 is the spectral half - width at the 1/@xmath31-intensity point .
equation ( [ eq : t ] ) indicates that pulse focusing occurs only when @xmath48 , where an up - chirped @xmath49 ( down - chirped @xmath50 ) pulse is used as an input in an anomalous ( normal ) dispersion regime @xmath51 ( @xmath52 ) . as an experimental demonstration in this device
, an up - chirped pulse is injected in the anomalous dispersion regime between 3.5 - 7 mhz as shown in fig .
4(a ) .
the output pulse width is measured at various distances by exciting different chirped pulses with a centre frequency of 5.8 mhz as shown in figs .
4(b)-(d ) .
the pulse widths with negative @xmath45 monotonically increase with increasing distance ( see fig .
4(b ) and the upper panel of fig .
4(c ) ) , whereas the widths with a positive @xmath45 first decrease to the transform limited value , and in turn , increase with distance ( see fig .
4(b ) and the lower panel of fig .
4(c ) ) .
it should be also noted that a smaller pulse width is observed when we employ a larger absolute value of positive @xmath45 and indeed , strong focusing is realized when @xmath53 where the pulse width is compressed from 2 @xmath0s to 0.5 @xmath0s and the strain energy is enhanced more than one order of magnitude . making use of the gvd effect enables a travelling pulse waveform to be engineered that leads to the temporal focusing of phonons . in a conventional spatial lens ,
the figures of merit such as the compression and amplification factors , and the ability to spatially adjust the focusing position , are mainly determined by the geometric parameters of the system .
therefore , these techniques require sophisticated artificial structures if they are to control waves .
in contrast this time lens enables them to be dynamically designed by simply changing the excitation frequency , input pulse width and chirp parameters .
although , in this study , these focusing properties are limited by the device structure causing the reflection at both wg edges , and the finite bandwidth of the lock - in amplifier , it is possible to further enhance this focusing effect by modifying the device structure and optimizing the measurement set - up . in conclusion
, we have demonstrated a phononic time lens in a 1d pnc wg .
the dispersion effect determined by the periodic geometry of the device induces frequency chirp in the gaussian input pulse during propagation .
this phenomenon also allows the travelling wave to be temporally focused , and this can be controlled by changing the input chirp parameters .
this novel temporal focusing can enhance the availability of mobile phonons , and this ability will open up potential applications to investigate nonlinear phononic phenomena .
+ + * methods * + nanomechanical vibrations in the pnc wg were excited by applying an amplitude modulated alternating voltage from a signal generator ( nf wavefactory 1974 and 1968 ) , and were measured with a he - ne laser doppler interferometer ( neoark mld-230v-200-nn ) . in the spectral measurements in fig .
1(b ) , the electrical output from the interferometer was measured with a vector signal analyzer ( hp89410a ) . in the temporal measurements in figs .
2(a ) , 3(b)-(c ) and 4(b)-(c ) , the electrical output was first filtered by a lock - in amplifier ( zurich instruments hf2li ) , and then measured with an oscilloscope ( agilent dso6014a ) .
the spectral bandwidth of the low - pass filter in the lock - in amplifier was set at 470 khz , which is equivalent a time constant of 102.6 ns .

– Editor & Publisher and Kirkus Reviews will shut down after the Nielsen Company today sold off most of its other magazine properties—including Billboard and the Hollywood Reporter—to a new media consortium. Nielsen spun the move as a chance “to strengthen investment in our core businesses,” reports Business Insider. But the loss of the prominent trade publications shook the publishing industry. The 108-year-old E&P is "the industry bible of newspapering," True/Slant observes, and the eBookNewser blog describes the shuttering of Kirkus as "a big blow." Other publications sold to e5 Global Media Holdings include Brandweek, Mediaweek, Backstage, and Adweek, which broke the story. Nielsen said it will “continue to assess the strategic fit of our remaining portfolio of publications.” | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | In a just-released message, Greg Farrar, President of Nielsen Business Media, announced the company's decision to cease operations on two important publishing industry publications: Kirkus Reviews and Editor & Publisher. Nielsen will also sell eight other magazines, including Backstage and Billboard, to a newly formed company called e5 Media Holdings. Click here to read the notice (via Poynter Online and Jim Romenesko). This is a big blow to the publishing industry, if not to the eBook sector specifically. With the closure of Kirkus, we do lose an important online source of reviews, though one that lives mostly behind a subscriber pay wall. There is, of course, much talk about this news on Twitter. Notably, Ron Charles of the Washington Post said, "For me, they were the last reliable source of negative reviews." Charles also notes that the last tweet from the Kirkus Reviews was 17 hours ago. ||||| As if anyone still working with print needed even more bad news — more than 24,000 of us canned in the past year alone — today brings the news that Kirkus Reviews, which reviews 500 books pre-publication, and Editor & Publisher, the industry bible of newspapering are being shut down. No word whether their digital counterparts will live, although it’s hard to imagine they wouldn’t. No matter how much their insider information seems old-school to some, it’s essential to others. Any author hoping for decent sales liked to get a nod from Kirkus, Booklist and Library Journal, which tended, back when there were book reviewers for…oh, yeah, newspapers…to drive their reviewers’ decisions about what to pluck from the annual 200,000 books pumped out every year. With fewer and fewer places to even get a book reviewed, at least in print, anything that narrows a new book’s, or author’s, chances of being discovered, sold and read is a sad thing. E& P, whose website bills it as “the oldest journal covering the newspaper industry” is only the latest casualty in the past few months, as trades and consumer glossies alike, such as Gourmet, have been closed for good. Who’s next? |

– The future of the House of Representatives was again the focus of the Sunday talk shows today, with Newt Gingrich predicting that the GOP could beat his '94 uprising, which claimed 54 seats from Democrats. “The high is probably around 60,” he told Fox News Sunday. “I think Boehner is the speaker, and Pelosi has to decide whether to stay." She's not going anywhere, countered Steny Hoyer: While acknowledging his party would lose some seats, he told CNN, "We're going to hold the House." Elsewhere on the dial, as per Politico: The AP reports that would-be speaker John Boehner, who got a little testy with Bob Schieffer's questioning of his smoking, said he would vote to extend middle-class tax cuts, even if it didn't include those for the top 2%. Attaboy, says Gingrich: “I think that the Republicans would be very wise to say we’ll pass any tax cuts that the president will sign." Janet Napolitano, meanwhile, told CNN that while security gains have been made since 9/11, the United States is “never going to be totally immune from threats.” | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | 7 years ago House Majority Leader Steny Hoyer expressed confidence Sunday in Democratic congressional candidates. (CNN) - House Majority Leader Steny Hoyer on Sunday expressed his confidence in congressional Democrats’ ability to maintain their majority in the House of Representatives, but conceded his party will “probably” lose seats. “We’re going to hold the House,” Hoyer repeatedly told CNN’s Candy Crowley on "State of the Union." “Our candidates are feeling good,” Hoyer added. The two leading non-partisan political handicappers, Stuart Rothenberg and Charlie Cook, both predict massive Republican gains in the House this November. The Rothenberg Political Report upped its prediction on Tuesday to 37 to 42 additional seats for Republicans and said that gains of 45 to 55 seats are possible. The Cook Political Report predicts GOP gains of at least 40 seats. Republicans must gain 39 seats in the House to retake the majority. Hoyer said his party may have to abandon some of its candidates if they fall too far behind and stand no chance of winning election. “If there are candidates that are very substantially behind and can’t make it, clearly we will have to make some tough judgments,” Hoyer said. ||||| 7 years ago (CNN) - Homeland Security Secretary Janet Napolitano said on Sunday that the United States is “never going to be totally immune from threats” to its national security. One day after the ninth anniversary of the September 11, 2001 terrorist attacks, Napolitano said in an interview with CNN’s Candy Crowley on "State of the Union" that the country is safer now than it was then, but added, “there is no 100 percent guarantee” that we won’t be attacked again. Former Homeland Security Secretary Michael Chertoff echoed Napolitano’s assessment. “We have reduced the risk, we have not eliminated the risk,” Chertoff told Crowley on Sunday. Napolitano said a small number of American citizens have become “radicalized to violence,” but said that it is “not unique” to the United States, “nor was it unanticipated that that could occur.” |

– Charleville, Australia, had a huge shindig prepared for the town's 150th anniversary. Then they realized that they were three years too late. Mayor Annie Liston says some locals believed the town of 5,000 people was officially recognized in 1868, but a check of Queensland state records revealed that the correct year was 1865, the BBC reports. She says the confusion was compounded by disagreements among local historians about the date—and by the fact that many town records were lost in a flood years ago. Liston says the anniversary party had been planned for more than a year, and it will go on despite the mix-up the Telegraph reports. "We'll still celebrate what we missed out on, the 150, so we'll have to do something around the 153rd," she says. "We don't really need an excuse for a party." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | An Australian town has missed its own 150th anniversary after planning the party three years too late. Charleville in south-west Queensland had planned to celebrate next year, believing the town had been founded in 1868. However, historians researching the exact date of Charleville’s inception discovered the historic date was actually 1865. Mayor Annie Liston admitted the town was “disappointed”, blaming the confusion on a “conflict between two researchers”. “There had been a couple of historians who have researched the history of Charleville,” she told The Telegraph. ||||| Image copyright Murweh Shire Council Image caption Local authorities will make plans for an alternative celebration Plans to celebrate the 150th anniversary of an Australian town have hit a hurdle, after local authorities found they were three years too late. The town of Charleville, in Queensland, had begun planning festivities for next year to mark what locals believed was its official recognition in 1868. However, a check of state records showed the historic moment had actually taken place in 1865. Mayor Annie Liston said it was a disappointment. "We put so much budget towards it, then we found out it was gone. It was the biggest shock to all of us, I can tell you," she told the BBC. "We were all prepared to have this big shindig next year and [the date] is not even correct." She said local historians had provided conflicting dates in the past and some records were lost in a flood. Charleville resident Laurie Parker told Australia's ABC: "There's other things we've been concentrating on here and we've been wanting to get rain [to prevent drought] and pick up the economy and things like that, but certainly those sort of birthdays are important to celebrate." The town of about 3,300 people will make alternative plans. "We're still planning on having some sort of celebration next year - the event staff are currently trying to organise what form the event will take at this stage," Mayor Liston said. |

– Mary-Kate Olsen and Olivier Sarkozy, subjects of some of the creepiest photographs of all time, may be taking creepy pictures together 'til death do them part. Sources tell Page Six that Olsen, 27, has been seen engagement ring shopping numerous times lately at Neil Lane in LA, looking at what one source refers to as "huge" rings. All of her choices have been more than 5 carats and set in platinum, and some cost more than $100,000. "I don't think price was an issue," says another source. Sarkozy, 44, the half-brother of the former French prez, wasn't with her on any of the trips.

we demonstrate that ramsey spectroscopy can be used to observe rydberg - dressed interactions .
in contrast to many prior proposals , our scheme operates comfortably within experimentally measured lifetimes , and accesses a regime where quantum superpositions are crucial .
we build a spin-1/2 from one level that is rydberg - dressed and another that is not .
these levels may be hyperfine or long - lived electronic states .
an ising spin model governs the ramsey dynamics , for which we derive an exact solution . due to the structure of rydberg interactions ,
the dynamics differs significantly from that in other spin systems .
as one example , spin echo can _ increase _ the rate at which coherence decays .
the results also apply to bare ( undressed ) rydberg states as a special case , for which we quantitatively reproduce recent ultrafast experiments without fitting .
pacs numbers : : 32.80ee , 67.85.-d , 37.10.jk _ introduction _ - ultracold rydberg atoms allow one to process quantum information @xcite , study interacting many - body systems @xcite , and engineer nonlinear quantum optics @xcite .
these applications stem from the enormous van der waals interactions between rydberg atoms excited to large principal quantum number @xmath0 .
since these interactions are proportional to @xmath1 , they are enhanced by many orders of magnitude compared to ground state atoms @xcite .
these interactions inhibit the simultaneous excitation of neighbouring atoms to rydberg states ; this is known as the blockade effect " @xcite .
experiments have observed dramatic consequences of rydberg interactions , such as the formation of rydberg crystals @xcite and suppressed excitation number fluctuations in the blockade region @xcite .
however , observing quantum correlations remains an outstanding challenge .
quantum correlations require superpositions , which in turn require non - commuting terms in the governing hamiltonian .
obtaining such a situation is difficult with pure rydbergs , since their interaction energy often dominates the other scales .
consequently , in order to explore the many interesting applications where superpositions and quantum correlations are essential @xcite , it is necessary to controllably reduce the interaction strength for example , one may seek to make it comparable to the rabi drive in a blockade experiment or comparable to motional energy scales in a trap or lattice .
dressed rydberg atoms , in which a small rydberg fraction is superposed with the ground state , enable this control while simultaneously extending the system lifetime by reducing spontaneous emission @xcite .
an exciting recent breakthrough is the measurement of dressed rydberg interactions between two atoms @xcite , but observing these interactions in a many - body system remains a major outstanding goal .
, purple ) weakly mixes the rydberg state @xmath2 into @xmath3 to form the dressed state @xmath4 .
this state is probed with strong pulses ( @xmath5 , red ) that couple @xmath6 and @xmath3 .
( b ) the rydberg - dressed interaction for the @xmath7 case considered herein is a soft - core potential .
( c ) ramsey scheme : an initial @xmath5 pulse with area @xmath8 superposes @xmath9 and @xmath10 states .
dressed atoms interact between pulses .
the final pulse allows one to measure the spin vector .
one can apply a @xmath11 echo pulse to eliminate single particle imperfections .
this also effectively
turns on " the interactions between atoms that were initially in the ground state for the second half of the dynamics . ] in this paper , we show how current experiments can observe and characterize dressed rydberg interactions by using ramsey spectroscopy , where one probes a spin-1/2 created from two long - lived atomic states , one of which is rydberg dressed .
this ramsey protocol directly accesses a regime where superpositions are crucial and can give rise to non - classical correlations .
although similar to the ramsey protocol that has been fruitfully applied to other many - body atomic and molecular systems @xcite , we find that the rydberg atoms behave in qualitatively different ways because of the shape of the potential and because the ground - rydberg and ground - ground interactions are negligible compared to the rydberg - rydberg interactions .
the unique character of the dressed rydberg interaction also manifests itself in the dependence of the dynamics on atom density , dressed state excitation fraction , spin echo , and rydberg state .
just one example of this distinct behavior is that the contrast decay is _ faster _ with an echo than without in several regimes , including low density , large dissipation , and small excitation fraction of dressed states .
_ setup : rydberg dressing , interactions , and spectroscopy - _ we consider an atom with two long - lived levels @xmath12 and @xmath3 as shown in fig .
[ setupfig](a ) .
these could , for example , be two hyperfine states or the ground state and another sufficiently long - lived electronic state .
examples of long - lived electronic states occur in the alkaline - earth - like atoms : the @xmath13p@xmath14 or @xmath13p@xmath15 states have lifetimes of @xmath16 s and 21 @xmath17s respectively .
we consider the same coupling scheme as in ref .
@xcite .
a laser with rabi frequency @xmath18 and detuning @xmath19 from resonance admixes a small fraction of the rydberg state @xmath2 to the @xmath3 level , creating a rydberg - dressed state @xmath20 with @xmath21 .
our spin-1/2 system is then formed from @xmath22 and @xmath23 . here
we assume that the positions of the atoms are fixed , which is an excellent approximation for ultracold systems over the timescales we consider .
the interaction hamiltonian for such a gas of atoms projected onto the spin-1/2 states is , up to a irrelevant constant , @xmath24\ ] ] where the pauli spin operators are @xmath25 , @xmath26 , and @xmath27 .
the interaction between dressed atoms @xmath28 and @xmath29 with inter - atomic distance @xmath30 is @xmath31 .
here @xmath32 is the van der waals coefficient , @xmath33 is the soft - core radius , and @xmath34 is the height of the dressed potential ( we set @xmath35 ) .
this hamiltonian is unique to rydberg atoms in the sense that the coefficients of the ising term and the single particle term are linked .
this is because the interactions are dominated by the rydberg states while interactions involving ground states are negligible .
figure [ setupfig](c ) shows the ramsey protocols studied here .
the first strong , resonant pulse , @xmath36 , rotates the spins by @xmath8 around the @xmath37-axis .
the wave function immediately after this pulse is @xmath38 where @xmath8 is proportional to the pulse area . during the ramsey dark time @xmath39
, the system evolves by eq .
( 1 ) , developing correlations . after this time @xmath39
, a second pulse rotates the spin component @xmath40 into the @xmath41 axis , where it can be measured as the population difference of @xmath4 and @xmath6 .
the incoherent emission from @xmath3 is described by a master equation with jump operator @xmath42 and rate @xmath43 ( see fig .
[ setupfig](c ) ) .
it is convenient to measure and analyze the ramsey contrast @xmath44 and the phase , @xmath45 .
here we defined @xmath46 .
we study the dynamics both with and without a spin - echo pulse , illustrated in fig .
[ setupfig](b ) .
a @xmath11 spin - echo pulse around the @xmath37 axis ( i.e. in phase with the first pulse ) leaves the spin - model interactions invariant while removing single particle terms from the hamiltonian eq .
( [ spineq ] ) , as well as any additional single - particle inhomogeneities in @xmath47 .
the resulting dynamics are equivalent to evolution for time t _ without _ an echo but with effective hamiltonian , @xmath48 as shown in the supplementary material @xcite .
the spin - echo has rather unusual effects in the rydberg system as it effectively _ turns on _ interactions between the @xmath6 states , as illustrated in fig .
[ setupfig](c ) . dressed with @xmath49s triplet states with a dressing amplitude of @xmath50 .
panels ( a ) and ( b ) show @xmath51 and @xmath52 , respectively .
individual curves are for ramsey with and without spin echo , compared to that of non - interacting atoms spontaneously emitting from only @xmath53 with @xmath54s@xmath55 . ] _ calculating the ramsey contrast and phase - _ the spin dynamics of eq .
( 1 ) together with the non - trivial effects of the dissipation has been obtained by solving the corresponding master equation in refs .
@xcite ( generalizing refs .
@xcite ) , to obtain @xmath56 where @xmath57.\end{aligned}\ ] ] here @xmath58 is for echo while @xmath59 is for no echo dynamics .
the function @xmath60 often simplifies ; for example , @xmath61 for @xmath51 and @xmath62 .
another relevant decoherence is a dephasing of the @xmath3 level at rate @xmath63 as could result from laser noise ; this can be included simply by multiplying @xmath64 by @xmath65 .
we neglect such noise as it depends on the details of the experiment , and often is negligible compared to @xmath43 .
although eq .
( [ conphase ] ) allows us to calculate the dynamics once we know the atom positions , it often is impossible to measure the positions of all of the atoms .
however , in a large enough system , the dynamics is expected to self - average " : @xmath66 for a single configuration in a large system is equal to its average over all configurations , and therefore it is independent of the specific configuration .
we model the atoms to be independently distributed with a uniform density @xmath67 for simplicity .
the assumption is quantitatively justified for an initially weakly interacting , not - too - degenerate gas .
rather remarkably , we are able to analytically perform this disorder average in the thermodynamic limit : we find that eq .
( [ fullana ] ) simplifies to evaluating a one dimensional integral ( see supplementary material @xcite ) , @xmath68 \right).\ ] ] ) takes a dramatically different shape in the @xmath69 and @xmath70 limits .
interestingly , for @xmath71 the contrast dynamics is faster with echo than without , except at exceptionally short times ( inset ) .
the dashed lines are the analytic predictions of eq .
( 6 ) for these limits .

the top _
x_-axis represents the average number of rydberg excitations inside @xmath73 . ] _ characterizing rydberg - dressed interactions using ramsey scheme - _ in the absence of dissipation , eq .
( [ simpleana ] ) implies that the dimensionless parameters , @xmath74 and @xmath75 encapsulate the dependence of the dynamics on density @xmath67 , van der waals coefficient @xmath32 , and optical parameters ( @xmath18 , @xmath19 ) .
thus , we present the contrast in figs .
[ contrastdiss]- [ densityscaling ] as a function @xmath76 , from which one can easily extract the dynamics for any experiment by using the appropriate @xmath72 and @xmath77 . to show typical scales
, we also show the dynamics for typical sr experimental parameters @xcite with @xmath32 coefficients from ref .
@xcite .
figure [ contrastdiss](a ) demonstrates that the interaction - driven dynamics occurs on an experimentally favorable timescale , both with and without a spin echo .
for example , in sr it is substantially faster than the spontaneous emission rate @xmath78s@xmath55 of the @xmath79 state .
typically the dynamics of the non - echo is faster than echo due to single particle inhomogeneities .
interestingly , due to the unique structure of the rydberg interactions , this naive intuition sometimes fails , as seen in fig .
[ contrastdiss](b ) for @xmath80 . in this case
, the spin - echo pulse increases the effective interactions since it converts initially non - interacting @xmath81 atoms into strongly interacting @xmath82 states .
figure [ densityscaling ] shows that the contrast is sensitive to the shape of the potential , with striking differences in the low - density ( @xmath83 ) and high - density ( @xmath84 ) limits .
these differences arise because for @xmath85 the dynamics probes the @xmath86 interaction tail , while for @xmath87 it probes the core . in these limits ,
the disorder - averaged contrast of eq .
( [ simpleana ] ) simplifies to @xmath88 with @xmath89 where @xmath90 is for echo dynamics and @xmath59 for non - echo dynamics . for @xmath85 ,
this contrast is the exact solution of eq .
( [ simpleana ] ) , and is non - analytic at @xmath91 ; thus it is beyond all orders of perturbation theory .
for @xmath84 , eq .
( [ ct ] ) approximates @xmath92 , where @xmath93 is the heaviside function . as shown in fig .
[ densityscaling](b ) , this simple model reproduces the exact contrast up to an overall shift of the timescale : the naive @xmath94 of the hard core potential is replaced by @xmath95 for the shown value of @xmath72 .
the scaling of the characteristic time @xmath96 , defined as @xmath97 , follows directly from eq .
( [ simpleana ] ) as @xmath98 where @xmath99 for @xmath71 , while @xmath100 for @xmath84 .
this scaling is confirmed in fig .
[ densityscaling](c ) , where we also include results for sr with dissipation .
fig .
[ densityscaling](c ) s top axis shows @xmath101 , which must be small in order for eq .
( [ spineq ] ) be valid .
although fig .
[ densityscaling](c ) shows that the dissipation substantially increases the rate of contrast decay , this is not due to to naive single - particle decay , which occurs on the slow 21@xmath17s timescale , as shown in fig .
[ setupfig ] .
rather , this is due to the back action of the emission events on the rest of the spins through the interaction , which induces strong correlations ; this is analogous to the feedback effect explained in ref .
@xcite .
we note that losses due to ionization or molecular resonances are neglected in eq .
( [ fullana ] ) .
one way to avoid resonances is to confine atoms in a lattice with appropriate lattice spacings @xcite .
recently it has also been shown that for large number of atoms , losses to other dipole allowed rydberg states can be significant @xcite .
all of these are beyond the scope of this paper , but often should be relevant only on timescales beyond those of interest here .
square lattice .
dressing parameters are the same as in fig .
[ contrastdiss ] .
the lattice spacing is @xmath102 m and @xmath103 .
the connected correlation functions @xmath104 between the center atom and the surrounding atoms is shown in the insets . ]
_ correlations using rydberg - dressed interactions in a lattice - _ our calculations so far have been for a gas where both the excitation and measurement are done collectively on the whole system ; this is the typical and most straightforward case in current experiments .
however , it is also possible to spatially resolve @xmath105 @xcite .
the extreme limit of this capability is the single atom resolution that has recently been achieved in microscope experiments @xcite .
the images in these experiments reveal not only @xmath105 , but also correlations such as @xmath106 .
motivated by these ongoing experiments , we study the ramsey dynamics on a unit - filled two - dimensional square lattice . fig .
[ g2fig ] shows the @xmath66 and snapshots of the connected correlation @xcite @xmath107 .
we observe that the shape and timescale of the contrast dynamics is similar to the @xmath84 limit found in the gas , and that the decay of the contrast is associated with a growth of strong spin correlations within a radius @xmath73 .
_ characterizing bare rydberg interactions using ultrafast lasers - _ to exemplify the generality of our calculations we consider the recently performed ultrafast ramsey experiment with bare rydberg states of rb atoms @xcite .
this can be viewed as a special case of rydberg - dressed atoms with @xmath108 and @xmath109 , so one obtains a pure van der waals potential .
typically , due to strong blockade effects , it is hard to excite atoms to superpositions of ground and bare rydberg states at a sufficiently large density .
ref .
@xcite overcomes this difficulty using strong , ultrafast lasers to couple atoms from their ground state @xmath110 to the bare rydberg state @xmath111 .
we calculate the contrast and phase for this experiment using the @xmath32 coefficients from ref .
@xcite . fig .
[ rbpumpprobe ] shows our theory , which quantitatively agrees with experiment without any fitting and also coincides with the calculations in @xcite.this agreement confirms that the effects of zeeman degeneracies @xcite can be neglected and that the low fraction of rydberg excitation suppresses any resonances .
this provides a compelling proof of principle for this detection method in future ultracold rydberg - dressed experiments . to the contrast at @xmath112 .
( c , d ) are the corresponding ramsey phase shifted at @xmath91 as in the analysis in ref .
@xcite . ]
_ conclusion - _ although previous experiments on coherent many - body excitation with rydberg atoms have demonstrated strong correlations , they have not established their _ non - classicality_. ramsey spectroscopy directly creates and probes the superpositions necessary for quantum correlations .
we have shown that this dynamics happens on experimentally favorable timescales .
the exact analytic solutions available for the dynamics will allow for systematic comparison between experiment and theory , despite the strongly correlated dynamics . ( to emphasize the strong correlations , note that for @xmath51 , the dynamics is completely beyond mean - field theory , which predicts a time - independent spin - echo contrast ) .
we showed , as a first step in this direction , that our theory quantitatively agrees with recent ultrafast measurements of bare rydberg atoms , a remarkable demonstration of the universality of the dynamics over six orders of magnitude , from @xmath17s to ps .
we revealed that the contrast dynamics is sensitive to the shape of the interaction potential , as well as to density , principal quantum number , and dressing laser properties .
striking dynamics emerges for @xmath113 : the contrast displays a non - perturbative short time non - analyticity , @xmath114 , due to the @xmath86 character of rydberg interactions .
further interesting dynamical phenomena result from the unique nature of rydberg interactions .
for example , the spin echo pulse enhances the rate of contrast dynamics for small excitation fraction @xmath8 or low densities . in the future ,
ramsey experiments with local pulses applied at various phase delays would allow measurement of the quantumness in the correlations , and would pave the way for studying interesting many - body non - equilibrium spin physics .
another interesting direction is to simply add a transverse field .
this prevents exact solution and the resulting rich many - body dynamics will be an interesting testbed for theoretical methods @xcite .

– If you were still waiting for over-the-top reaction to Tim Cook's announcement last week that he is gay, we present you with Russia: Apparently outraged by the sexual orientation of the CEO of a California-based technology company, a construction company has taken down a six-foot statue of an iPhone erected on a St. Petersburg university campus as a memorial to Cook predecessor Steve Jobs, reports the AP. The company, ZEFS, likens Cook's coming out to "a public call to sodomy," and said today that it yanked the statue because it violated Russian laws that protect minors from "homosexual propaganda." It's not the only backlash in St. Petersburg: A prominent anti-gay activist has also called for Cook to be banned from Russia on the grounds that, as Radio Free Europe puts it, "he could bring AIDS, Ebola, or gonorrhea into the country." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | FILE- In this file photo dated Thursday, Jan. 10, 2013, a girl touches the screen showing a portrait of Steve Jobs on the recently erected memorial to late Apple Corp. co-founder in the courtyard of the...

(Associated Press) MOSCOW (AP) — A two-meter statue of an iPhone on a university campus in St. Petersburg has been taken down in response to last week's announcement by the CEO of Apple that he is gay. In a statement, ZEFS, which according to its website owns construction, advertising, and finance enterprises in St. Petersburg, describes Tim Cook's revelation "a public call to sodomy." ZEFS said Monday it was taking down the statue because it violated Russia's controversial law protecting minors from homosexual propaganda. The law has been condemned by critics as a means of repressing sexual minorities in the country. Apple did not immediately respond to a request for comment. ||||| Russian media reports say a big mock iPhone meant as a monument to the late former Apple CEO Steve Jobs has been taken down in St. Petersburg after his successor, Tim Cook, came out publicly as gay. The monument, with an interactive screen displaying information about Jobs, was reportedly put up on the grounds of an IT university in January 2013 on the initiative of a Russian company called Western European Financial Union. Russian Radio station Biznes-FM cited the company's chief, Maksim Dolgopolov, as saying he had it removed in part to comply with a law banning the spread of "propaganda of nontraditional sexual relations" among minors. After Cook came out as gay in an essay published on October 30, prominent St. Petersburg antigay activist Vitaly Milonov was quoted as saying Cook should be banned from Russia because he could bring AIDS, Ebola, or gonorrhea into the country. Based on reporting by Biznes-FM and gazeta.ru |

– In a case with sad echoes of the death of Cory Monteith, the boyfriend of another Glee star has been found dead in a hotel room. Becca Tobin, who plays Kitty Wilde on the show, was in Philadelphia with Matt Bendik; he runs several big nightclubs around the country and was in the city on business. The 35-year-old went out with his girlfriend and other friends Wednesday night; his body was found, in bed, by a hotel maid yesterday afternoon. It's not clear where Tobin was at the time, or whether she even left the club with him, TMZ reports. Investigators are calling it a "sudden death," and currently there is no evidence of suicide, foul play, or injuries to Bendik's body, sources say. Bendik may have died in his sleep; no drugs, drug paraphernalia, or weapons were found in the room, and the incident report makes no mention of alcohol or medications, according to law enforcement sources. Police were called to the room shortly after 1pm, and Bendik was pronounced dead at 1:17pm.

– Ricky Gervais has done it again. The boundary-busting, always irreverent funnyman has been accused of using a slur associated with people with Down syndrome on Twitter (here, here, and here)—and making goofy faces to go with the tweets. He was instantly called out on it, reports ABC News, but Gervais insisted the word he used no longer refers to someone with Down syndrome, but rather refers to "a div, a dozy spud-headed twonk," adding: "I would NEVER use it to mean Down syndrome.” Gay "used to mean happy. Words change. Get over it," he snapped. But he added that "the police" have "come round and confiscated all my awards."

Did Ricky Gervais cross the line by being his usual, I-could-care-less-what-people-think-about-me self? The British comedian evoked online ire after posting a series of tweets referencing “mongs,” once a slur directed at people with Down’s Syndrome, and sometimes accompanying them with photos of him making silly faces. “Two mongs don’t make a right,” read one tweet. “Night night monglets,” he told his followers on Oct. 14. Criticism came quick. Comedians and Down’s Syndrome advocacy groups have called out Gervais for reviving the word, but he claims “mong” now means something else. “Well done everyone who pointed out that Mong USED to be a derogatory term for DS,” he wrote, referring to Down’s Syndrome. “Gay USED to mean happy. Words change. Get over it.” Responding to a follower who asked “What is a mong?,” Gervais replied, “A div, a dozy spud headed twonk. I would NEVER use it to mean downs syndrome.” Gervais also circulated a page from InternetSlang.com decreeing that the definition of mong is “complete idiot.” Now the “Office” creator has turned the conversation about him into a joke of its own. “The police just came round and confiscated all my awards,” he tweeted today, along with the above photo. ||||| 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.

– It's the kind of story that almost has to come with a Portland dateline: It seems that on Monday evening, a concerned citizen called Portland's non-emergency line to report a chicken crossing the road. Prefacing his concern with, "Hi, um, this is actually not a prank call," the man proceeded to inform dispatch of the chicken, resulting in this conversation, as per the Oregonian: Dispatcher: "Is it causing traffic problems?" Concerned citizen: "Yes, it's really trying to go into the middle of the road." Dispatcher: "Uh ... yeah ... um, is it just the one chicken?" Concerned citizen: "Just one chicken, yeah." Dispatcher: "And you're ... is it ... I mean ... are, are people almost crashing because of it, or ... ?" Concerned citizen: "I had to slow down to almost to a complete stop." Unfortunately, responding officers saw no sign of the offending chicken, thus leading a police rep to tell the AP that police—wait for it—"were unable to determine the chicken's intent." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | A chicken crossing Highway 30 in Linnton caused minor traffic tie-ups Monday evening north of the St. Johns Bridge, Portland police said Tuesday. A motorist called the police's nonemergency line to report the hazard, prompting the following dialogue with a dispatcher. "Hi, um, this is actually not a prank call, but there is a chicken trying to cross the road in Linnton," the caller said. "Is it causing traffic problems?" the dispatcher asked. "Yes, it's really trying to go into the middle of the road," the caller replied. "Uh ... yeah ... um, is it just the one chicken?" asked the dispatcher. "Just one chicken, yeah." "And you're ... is it ... I mean ... are, are people almost crashing because of it, or ...?" "I had to slow down to almost to a complete stop." The dispatcher then assured the motorist that she would alert the authorities to the situation. No crashes were reported, and Portland police were unable to locate the chicken. They also emphasized that animals in a roadway are not a laughing matter and can create traffic hazards. If you see such a situation, police ask you to call their nonemergency line at 503-823-3333. Police also had no information on whether the chicken successfully completed the highway crossing or why it attempted the dangerous move. Listen to the nonemergency audio call below: ||||| PORTLAND, Ore. (AP) — Portland, Oregon, police were told there was a chicken — and it was attempting to cross the road. In fact, the citizen who called the police non-emergency line on Monday evening reported that the chicken's efforts to cross a road in a north Portland neighborhood were bringing traffic nearly to a standstill. He assured the dispatcher he was not joking. The dispatcher chuckled — and asked a clarifying question. "It's just the one chicken?" The caller said yes. Sgt. Pete Simpson says responding officers were unable to locate the chicken. And so, he notes, police "were unable to determine the chicken's intent." |

– Steve Bannon's fall from grace is now complete: President Trump has given the former White House strategist a disparaging nickname, much as he did with "Crooked" Hillary Clinton and "Crazy" Bernie Sanders. In an angry tweet late Thursday, Trump blasted both "Sloppy" Steve Bannon and author Michael Wolff (a co-founder of Newser), whose book Fire and Fury: Inside the Trump White House he's trying to block from release. "I authorized Zero access to White House (actually turned him down) for author of phony book!" the president wrote. "I never spoke to him for book. Full of lies, misrepresentations and sources that don’t exist. Look at this guy’s past and watch what happens to him and Sloppy Steve!" Following Trump's very public split with Bannon over remarks in Wolff's book, "that name is gonna stick," predicts Mediaite. (Wolff's book is going on sale early.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | We have a new nickname, folks! While President Donald Trump had released a statement hammering former White House chief strategist Steve Bannon over comments he made to author Michael Wolff, and had his lawyer issue cease and desist letters in an attempt to stop the release of Wolff’s upcoming White House tell-all, the president had remained largely silent on the matter on Twitter. That ended tonight. I authorized Zero access to White House (actually turned him down many times) for author of phony book! I never spoke to him for book. Full of lies, misrepresentations and sources that don’t exist. Look at this guy’s past and watch what happens to him and Sloppy Steve! — Donald J. Trump (@realDonaldTrump) January 5, 2018 As you can see in the tweet above, Trump made sure to blast both Wolff and Bannon.

– Note to future stepmothers: Never cut your stepkid’s hair, unless you want to get reamed on Twitter. Sadie Frost freaked out when Sienna Miller, reportedly engaged to Jude Law, gave Frost’s daughter with Law a boyish haircut. “I think ya should get ya own child and then cut their hair!” she ranted on Twitter, according to the Sun. Frost later deleted her Twitter account, but not before posting, “The story in paper is rubbish no-one cut Iris's hair she still has her beautiful locks. All is cool with them - peace and love,” the New York Post reports. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Click to email this to a friend (Opens in new window) Click to share on Twitter (Opens in new window) Click to share on Facebook (Opens in new window) Jude Law’s ex-wife Sadie Frost deleted her Twitter account Thursday, after an angry tweet exchange over their daughter’s new haircut. Frost had erupted in a fit of rage after Iris had her locks chopped off while staying with stepmom-to-be Sienna Miller, The Sun reported Thursday. The nine-year-old was staying with Law and film beauty Miller, who are due to wed soon, while she went to the Isle of Wight rock festival in southern England last weekend. When Frost returned, she reportedly found Iris with a boyish cut and erupted on Twitter with a message directed at 28-year-old Miller. “I think ya should get ya own child and then cut their hair,” the mom of four, 42, wrote. Frost later backtracked, posting: “The story in paper is rubbish no-one cut Iris’s hair she still has her beautiful locks. All is cool with them – peace and love,” before deleting her entire Twitter account. A friend of Frost’s told The Sun: “Sadie had a great time at the festival but it was all forgotten when she saw Iris’ hair. “It’s not that the style doesn’t look nice — it does — but that it was done without her permission. “I’m sure Sienna was just trying to be nice. But Sadie doesn’t want Sienna playing mum to her kids.” ||||| My View By LORRAINE KELLY Sun columnist SIENNA probably thought she was "bonding" with Iris, but she crossed a line and I'm not surprised that Sadie is annoyed. It's always difficult for any divorced mum to face up to the fact her kids have a "stepmother" figure in their lives. It's even tougher because Sienna is younger, prettier and more famous than Sadie. But I hope she hasn't been sour-faced and ranting in front of Iris, and simply tells Sienna calmly and quietly not to do any more makeovers. |

– The father of a self-described white nationalist who marched at Saturday’s “Unite the Right” rally in Charlottesville, Va., says his son is no longer welcome home. Pearce Tefft of Fargo, ND, posted the open letter on INFORUM Monday, writing that his son Peter’s values are not shared by his family. “I, along with all of his siblings and his entire family, wish to loudly repudiate my son’s vile, hateful, and racist rhetoric and actions,” he wrote. “We do not know specifically where he learned these beliefs. He did not learn them at home.” Peter was first identified by Twitter user Yes, You’re Racist in a grainy screengrab from a video taken during the rally, but he's also been interviewed by news outlets about his beliefs. Pearce said that Peter’s family members originally stayed silent about Peter’s white nationalist beliefs, but ultimately realized that was a mistake. “It was the silence of good people that allowed the Nazis to flourish the first time around, and it is the silence of good people that is allowing them to flourish now,” Pearce writes, adding that unless his son renounces his “hateful beliefs,” he “is not welcome at our family gatherings any longer.” Peter Tefft's nephew also denounced Peter in a statement to WDAY: “He scares us all, we don’t feel safe around him, and we don’t know how he came to be this way.” Pearce ended his letter with a powerful response to a joke his son made about putting anti-fascists in ovens, writing: “Peter, you will have to shovel our bodies into the oven, too. Please son, renounce the hate, accept and love all.” | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | The post from a popular Twitter page called "Yes, You're Racist" points to Pete Tefft of Fargo. It's sparked thousands of retweets and likes, as well as many threats of violence. RELATED: Local family members also report being harassed. The 'Unite the Right' rally in Charlottesville turned deadly this weekend when a man drove a car into a crowd that was protesting the white nationalists. One woman died and at least 19 others were hurt. In February, Tefft responded to flyers in downtown Fargo that called him a Nazi. In an video interview with The Forum, he said he was interested in political action to further pro-white interests. Statement by Jacob Scott, Pete Tefft's nephew: "In brief, we reject him wholly – both him personally as a vile person who has HIMSELF made violent threats against our family, and also his hideous ideology, which we abhor. We are all bleeding-heart liberals who believe in the fundamental equality of all human beings. Peter is a maniac, who has turned away from all of us and gone down some insane internet rabbit-hole, and turned into a crazy nazi. He scares us all, we don't feel safe around him, and we don't know how he came to be this way. My grandfather feels especially grieved, as though he has failed as a father." "Several members of our family have been being harassed or threatened by random strangers, due to our connection with Peter. I know in particular that Peter's sister... has been contacted or threatened at her workplace, under the assumption that she must be a nazi or endorse nazism. We also have some relatives who live in..., who have randomly found themselves attacked, including a... year old girl, my cousin, named... who has supposedly been messaged online by at least one random stranger in a threatening manner.

– To all the women living in Manhattan, now might be an economically sensible time to head over to SoHo and stock up on all your feminine products, because neighborhood pharmacy Thompson Chemists just might be waiving your 7% "pink tax." Owner Jolie Alony tells Gothamist that she wants to "bring awareness on how it feels to be a woman, so the men actually get to feel it," by which she is referring to the fact that women pay roughly 7% more for personal products marketed to women than they would for the equivalent product marketed to men, as a recent NYC Department of Consumer Affairs report found. The 7% difference is often called the "pink tax" or "tampon tax," and the Daily Dot reports that there's more: Women's clothes cost more to dry clean, for example, and in many states menstrual products are actually taxed as luxury goods. On Monday, Alony posted two signs out front: "All female customers shop tax free" and "All male customers are subject to a 7% man tax." It's a bit misleading, as Time reports, given pricing didn't change at all for men but was dropped 7% for women (Alony must still pay sales tax in full, so she's paying the difference out of pocket). She wasn't sure whether she would continue the promotion past Monday. And while she said that at the shop her female customers were "very, very happy" and the men "just laughed," the story's gone viral and the pharmacy's Facebook page is riddled with one-star reviews and comments decrying the store's "sexist and hateful business practices" and calling the owners "idiots." Apparently they didn't heed the pharmacy's request to "please avoid locker room banter." (Read about why the trip a mom and daughter took to buy tampons went viral.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | This crawl of online resources of the 115th US Congress was performed on behalf of The United States National Archives & Records ||||| Over the past few years, there’s been an increasing movement to do away with the “tampon tax,” and other taxes that activists say put an undue burden on women. For instance, in many states, menstrual products are taxed as luxury items, and a woman’s blouse costs more to dry clean than a man’s button-down shirt, even if they'remade of the exact same material. Paired with the wage gap, any extraneous costs lead to an even greater disparity in income between men and women. Now, one Manhattan pharmacy is trying to solve that gap with a 7 percent man tax. Thompson Chemists owner Jolie Alony told the Daily Dot she put up the sign today, and it’s already gotten a lot of reaction. “We thought it’d be a great idea with all the political things going on—with Clinton being such a woman and the other guy and his womanizing,” she said. Citing the “pink tax,” she said, “We wanted to share that women deserve to get a break, and men deserve to be charged 7 percent more. Women are spending more in general and we make less, so we deserve to have a break.” Alony said a few couples have come in and gotten a kick out of the sign, including one woman who said 80 percent of the stuff in the bathroom belongs to her boyfriend anyway. “Other couples were a little upset about it, saying, 'Fuck you,' 'You’re being a sexist,' and to get a lawyer,” said Alony. “We live in a big world, and I think we need to raise awareness.” Alony says it’s up in the air how long the promotion will last, especially since "the disclosure of differing prices or fees based upon gender by a retail service establishment" is a violation of New York City pricing laws. For now, though, Thompson Chemists they're paying the difference in prices out of their pockets. So if you’re a woman in New York City, maybe it’s time to stock up on some essentials. |

– Tragedy in Atlanta last night, where the Journal-Constitution reports a 29-year-old man died after falling from the upper deck at Turner Field. He tumbled some 65 feet and landed in a parking lot outside of the stadium. Still no word on what caused Ronald Homer to fall, but a police rep says, "at this time, there is no indication of foul play and the fall appears accidental." Heavy rains had led to a nearly two-hour delay of the Braves vs. Philadelphia Phillies game, which was scheduled to start at 7:10pm, notes the AP. The Journal-Constitution adds that a 25-year-old fell 150 feet from the upper deck in May 2008, and also died. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Just One More Thing...

Close ||||| A man was hospitalized Monday night after falling 30 to 40 feet from an upper deck at Turner Field during a baseball game between the Atlanta Braves and Philadelphia Phillies. The unidentified man was listed in serious condition at a local hospital, Atlanta Fire Rescue Department spokeswoman Janet Ward said. Details on exactly how the man fell _ and what part of the stadium the incident occurred in _ weren't immediately available. Heavy rains had led to a nearly two-hour delay of the game, which was scheduled to start at 7:10 p.m. A Braves spokeswoman referred calls to the Atlanta police. A police spokesman did not immediately return a message. Monday's accident wasn't the first of its kind to happen at Turner Field, and marked at least the third time a sports fan has fallen from the stands in Atlanta in about a year. Isaac Grubb, 20, of Lenoir City, Tenn. died after falling over a railing at the Georgia Dome during a football game between Tennessee and North Carolina State on Aug. 31, 2012. Authorities said he landed on another man seated in the lower level, and that alcohol was a factor. A man fell about 25 feet over a staircase railing at a Georgia Tech-Miami football game on Sept. 22, 2012 and was not seriously injured. In May 2008, a 25-year-old Cumming, Ga. man suffered head injuries when he fell down a stairwell at Turner Field during a game against the New York Mets and later died. Police found that alcohol had factored into that accident, which the Braves said was the first non-medical fatality to happen at the ballpark. Turner Field became the home of the Braves in 1997, a year after serving as the site of major events for the 1996 Summer Olympics. |

– When 20-year-old Hollie Gazzard was stabbed to death by ex-boyfriend Asher Maslin in February 2014, Facebook froze the UK woman's profile to memorialize her, as it does with users when they die. Only Gazzard's account contains nine images of herself with Maslin—who was sentenced to life in prison five months after her murder—making her Facebook profile a place that her father says is "distressing" and "makes me sick," reports the BBC. "We understand in tragic cases such as this it may mean there are sometimes painful reminders, but memorialized accounts are designed to preserve the privacy of the deceased," a Facebook rep says. So her father, Nick Gazzard, has started an online petition at Change.org to remove the nine images, most of which are only viewable to those who were Facebook friends with Hollie Gazzard. "While we appreciate that Facebook [has] to have policies in place, all we are asking for is for them not [to] take a blanket approach and dismiss individual requests," he tells the Gloucester Citizen, adding: "While this is an issue on Hollie's account, I am sure that we are not the only ones in this situation and there will be many more going forward." Gazzard's petition had just over 10,000 signatures as of this writing.

"The petition was signed by more than 7,000 people in the first 24 hours and we hope that this continues and makes Facebook sit up and take notice. "While this is an issue on Hollie's account, I am sure that we are not the only ones in this situation and there will be many more going forward with more than 100 women losing their lives to current or ex-partners each year through domestic abuse.

– A Texas family's ride to view a Christmas lights display ended in tragedy Monday night when their car was rear-ended, killing the two oldest kids, WFAA reports. The Haltom City mom and dad and their three children had just completed a drive-through of the Christmas lights extravaganza at Texas Motor Speedway and were on their way home "in their car singing Christmas carols," the deceased's aunt tells the station. "My sister said within seconds everything turned to chaos." That chaos came in the form of a Ford Explorer that smashed into the back of the family's car, killing 23-year-old Alexander Trejo and his 19-year-old sister, Gabrielle Estelle. The local medical examiner says the two victims, who had to be pulled from their Ford Fusion, died of blunt force trauma, per the Star-Telegram. "We were laughing, giggling, singing Christmas songs, and then the next thing I know is I blacked out," 17-year-old Zachary, the sole surviving sibling, tells Fox 4 News. Zachary's parents were both hospitalized after the accident with injuries that were said to be non-life-threatening, per a GoFundMe page set up by the mom's co-workers. Fort Worth police are still trying to figure out what caused the Ford Explorer to plow into the family's car, WFAA reports; as of now, the driver of the SUV isn't facing any criminal charges. Meanwhile, family and friends held a tribute Wednesday night for Alexander, who had a love of music, and Gabrielle, said to be an aspiring photographer, Fox 4 News notes.

Michelle Flores, who works with their mother Dee Estelle, and her co-workers are turning their grief into action, setting up a GoFundMe page, which has raised more than $8,000 as of Wednesday night. "If we can't do anything else, we can at least help them financially because they have a long road ahead of them," Flores said.

– The US birthrate last year was the lowest since records began in 1920, dropping to 63.2 per 1,000 women, Pew data shows. Between 2007 and 2010, the rate fell 8% among all women aged 15 to 44. It fell 14% among foreign-born women, compared to 6% among women born in the US. And among Mexican immigrant women, it dropped 23%. The recession appears to have played a major role: Foreign-born women were deeply affected by the downturn, and Hispanic women born in the US and abroad have seen household wealth drop more than any other group since 2007. "Latinos have been hit particularly hard by the recession, and the downturn in births is especially sharp for immigrants," says a study author. Latino women's increased access to contraception may also have been a factor, analysts say. Another factor: Immigration from Mexico hit a net zero in 2010, the Wall Street Journal notes, meaning that the number of Mexicans moving here matched the number returning to Mexico. Some 3.95 million babies were born in the US last year, the data shows.

The rate fell sharpest for those hardest hit by the recession: 14% among foreign-born women and 23% among Mexican immigrant women in particular. The 2011 rate was the lowest since 1920, when such records began.

– From Bruce Jenner to Caitlyn Jenner to ... Senator Jenner? The transgender activist said during an interview on New York's AM 970 over the weekend that she's considering a run for the Senate in California, reports the Hill. The former Olympian is a lifelong Republican and supporter of President Trump, which the Los Angeles Times notes won't necessarily help her cause in blue California. But she also has publicly disagreed with Trump over transgender policy. "I have considered it," Jenner, 67, said in the interview. She added that she likes politics but is debating whether she can be more productive as an insider or an outsider, noting, "I gotta find out where I can do a better job." The next Senate election in the state is 2018, when Democrat Dianne Feinstein's seat will be up for grabs. Feinstein, 84, has not said whether she'll seek re-election, and no big-name Republican has stepped up so far.

I like the political side of it,” Jenner, who is a Republican, told Catsimatidis on AM 970 in New York. ADVERTISEMENT “The political side of it has always been very intriguing to me. Over the next six months or so, I gotta find out where I can do a better job. Can I do a better job from the outside? Kind of working the perimeter of the political scene, being open to talking to anybody? Or are you better from the inside, and we are in the process of determining that,” she said. “Yeah but I would look for a senatorial run,” she continued. Jenner told CNN's Don Lemon in April she would "seriously look at a run for office." Jenner has been a supporter of President Trump, but hit Trump earlier this year over his decision to roll back Obama-era protections for transgender students. “I have a message for President Trump from, well, one Republican to another. This is a disaster. And you can still fix it. You made a promise to protect the LGBTQ community. Call me," she said.

we have used the pibeta detector @xcite , a non - magnetic , segmented , pure csi spherical calorimeter supplemented with a pair of cylindrical multi - wire proportional chambers for the charged particle tracking and a plastic veto hodoscope for the particle identification ( fig [ fig : pb_det ] ) .
[ h ] the primary goal of the experiment has been to determine the pion beta decay ( @xmath1 ) branching ratio with @xmath7% uncertainty , improving the precision of previous measurements by almost an order of magnitude @xcite .
pion beta decay provides the theoretically most unambiguous means to study weak @xmath8-@xmath9 quark mixing which directly tests quark - lepton universality and can thus constrain certain aspects of physics beyond the present standard model . in the pibeta experiment a total of @xmath10 @xmath5 beam stops
were recorded during several running periods spanning three years .
the beam pions were counted by a tight fourfold coincidence between ( 1 ) a forward beam counter bc , ( 2 ) active degrader ad , ( 3 ) active target at , and ( 4 ) rf accelerator signal .
the non - pionic beam contamination determined by the time - of - flight method was small , 0.4@xmath11% @xmath12 s and 0.2@xmath11% @xmath6 s , respectively .

we have designed fast analog hardware triggers optimized to accept nearly all non - prompt processes contained in the calorimeter with an individual shower energy exceeding the michel endpoint ( high threshold @xmath13 52mev ) , while keeping the accidental rate to an acceptable level .
we have also implemented an analogous set of electronically prescaled triggers with the low threshold of @xmath13 5mev .
we have run with multiple simultaneous physics and calibration triggers at the @xmath5 stopping rate of @xmath14/s as well at a set of reduced beam fluxes down to @xmath15/s , which was crucial for a reliable understanding of the detector response .

– It was too early for the gooseberry glazed barramundi or the Faroe Islands heritage salmon, but some good meals are still in store for a starving sea lion pup that found its way into one of San Diego's fanciest seafood restaurants. The eight-month-old female was taken to SeaWorld's Animal Rescue Center on Thursday after staff at the Marine Room in La Jolla discovered it asleep in a booth, reports the BBC. Chef Bernard Guillas joked that the pup has asked to see the menu after it made its way through the back door from the beach. The pup was dehydrated and malnourished. Experts say the El Nino weather pattern has caused higher ocean temperatures, driving up sea lion mortality as they are forced to seek food further out at sea. "This pup weighed 20 pounds when we rescued it," SeaWorld animal care supervisor Jody Westberg tells CNN. "It should be about 40 to 50 pounds out in the wild right now." SeaWorld—which treated the pup to a big meal after the rescue—says it hopes to return the pup to the wild after it makes a full recovery. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Media caption A sea lion pup was rescued from a San Diego restaurant A hungry sea lion has been rescued after finding its way into a restaurant in the US city of San Diego. Staff found the eight-month-old female pup, which was severely underweight and dehydrated, asleep in a booth. The pup was taken to SeaWorld's Animal Rescue Centre, where it is hoped she will recover. Experts say sea lion mortality is rising because their food supply has been hit by high ocean temperatures linked to the El Nino weather pattern. Chef Bernard Guillas said the sea lion had got into The Marine Room restaurant through the back door after making her way up from the beach next to the building. "She said 'Can I see the menu?' I asked if she had a reservation," said the chef, whose photos of the pup were widely shared on social media. Staff at SeaWorld treated the pup to a big meal after her rescue. ||||| Story highlights Sea lion pup snoozes in restaurant SeaWorld team is helping it bulk up (CNN) An underfed but overly cute sea lion cub is getting a lot of TLC after it waddled into an empty upscale California restaurant without a reservation. The staff of The Marine Room in La Jolla on Thursday snapped some shots of the sick little female cub who slept on a booth, hopped about and gazed at the surf through a window. The pup "was a little bit early for (the) high-tide breakfast reservation as it is this weekend on Sunday and Monday," quipped executive chef Bernard Guillas on his Facebook page. A SeaWorld team was called to the restaurant to pick up the malnourished sea lion. According to some reports, it may have made its way in overnight through an unlocked door. SeaWorld said the cutie likely sought food and shelter from a higher than normal tide. "This pup weighed 20 pounds when we rescued it," said SeaWorld's Jody Westberg.

we address the forces exerted by the electromagnetic field emitted by a planar fluctuating source on dielectric particles that have arose much interest because of their recently shown magnetodielectric behavior . in this context
, we analyze as a particular case the modification of the casimir and van der waals forces .
we study the effect of the source coherence length as well as the interplay between the force from the radiated field and that from the electric and magnetic dipoles induced on the particle .
this allows a control of these interactions as well as of the weight and interference effects between the fields from both kinds of induced dipoles , in particular when large changes in their differential scattering cross section occur due to kerker minimum forward or zero backward conditions ; thus opening new paths to nanoparticle ensembling and manipulation .
the influence of surface waves of the source is also studied .
magnetodielectric particles have recently attracted much attention due to their exotic properties as scatterers and nanoantennas @xcite .
it has been shown @xcite that some dielectric particles behave in this way exhibiting coupled electric and magnetic dipoles induced by the illuminating light field .
it is then of great interest to study their response to stochastic radiation forces , specifically those due the field of a planar fluctuating source @xcite .
many previous studies have dealt with this subject for atoms or non - magnetic nanoparticles with its application to delta - correlated thermal sources and blackbodies in connection with the van der waals ( vdw ) and casimir - polder ( c - p ) interactions @xcite . in this work
we deal with a more general kind of statistical sources , namely those that are spatially partially coherent and of the wide variety of those statistically homogeneous and isotropic @xcite .
their emission excites electric and magnetic dipoles of the particle in its near field that may be considered as a secondary source whose radiation interacts with the primary fluctuating source ; this giving rise to a new total force resulting from both the action of the field radiated by the primary source and that from the field emitted by these dipoles . at thermal wavelengths ,
the interaction from this secondary source constituted by the particle induced dipoles is interpreted as a liftshitz force @xcite , which at zero temperature becomes either those derived by vdw and c - p @xcite , depending on the distance and use , or not , of quasistatic formulations .
however , in our study , first the optical wavelengths are such that @xmath0 and hence planck energy becomes similar to that of the vacuum fluctuations : @xmath1\approx \frac{1}{2}\hbar\omega$ ] ; and second , due to the magnetic response of the nanoparticle , more forces come into play in addition to those that keep an analogy with these above quoted , thus allowing a larger number of degrees of freedom of relevance for particle ensembling and manipulation .
we do not restrict here to thermal wavelengthts , but rather consider a range of infrared and optical frequencies whose choice depends on the particle size .
then a particular case of our study is that analogous to those dipole forces induced by spontaneous electromagnetic field fluctuations . while the vacuum forces can become relatively negligible by conveniently manipulating the power intensity of the source
, we shall show that in other possible configurations and experimental designs they may predominate .
the geometry considered in this letter consists of two half - spaces .
the lower one ( @xmath2 ) is occupied by the source with its polarization currents and it will be denoted as @xmath3 ; whereas the upper one ( @xmath4 ) , denoted as @xmath5 , is free space and contains the particle .
the cartesian components of the force on a magnetodielectric dipolar particle is the sum of an electric , magnetic and electric - magnetic dipole interference parts which are expressed in terms of the first electric and magnetic mie coefficients @xmath6 and @xmath7 as @xcite @xmath8 where @xmath9 , @xmath10 and @xmath11 @xmath12 are the permittivity and susceptibility of the medium embedding the particle , respectively , in our case being vacuum ; and @xmath13 .
@xmath14 and @xmath15 standing for the electric and magnetic polarizability of the particle , respectively .
@xmath16 , @xmath17 ; @xmath18 is the total electric vector at frequency @xmath19 at any point of the half - space @xmath4 , hence at the position of the particle , i.e. at @xmath20 , it will be @xmath21 in the second line of this equation we have omitted the explicit dependency on space and frequency for brevity .
the associated magnetic field can be obtained directly from maxwell s equations . in eq .
( [ totfield ] ) the last two terms are the electric fields emitted by the particle induced dipoles ( @xmath22 and @xmath23 ) after multiple reflections at the plane @xmath24 @xcite and hence connect the constitutive properties of the source and particle through the reflection fresnel coefficients @xmath25 at @xmath24 and the polarizabilities , being described by @xmath26 . on the other hand , the first term @xmath27 represents the electric field _ incident _ on the particle after being emitted from the primary source placed at @xmath2 , and is defined through the green s function @xmath28 which includes the transmission fresnel coefficients @xmath29 from @xmath2 into @xmath4 .
@xmath28 may be written as a superposition of plane waves with wavevector @xmath30 with @xmath31 , @xmath32,(@xmath33 ) , and @xmath34 .
thus , in terms of the polarization currents one has @xmath35 in vacuum ( @xmath36 ) , @xmath37 decays exponentially with the distance in the evanescent wave region ( @xmath38 ) and is oscillatory in the radiative one ( @xmath39)@xcite . for a single dipole , this electric field is calculated from eq .
( 3 ) using @xmath40 and @xmath41 instead of @xmath28 and @xmath42 . in a similar way , the electric field @xmath43 generated by the magnetic dipole can be calculated from the green function associated to the magnetic field of the electric dipole @xmath44 and making the interchange @xmath45 in the reflection fresnel coefficients
. some details about these green s functions can be found in e.g. @xcite .
note that for p - polarization , both @xmath46 and @xmath47 support surface plasmon polaritons ( spps ) when @xmath48 .
now we define the cross - spectral density tensor of the source polarization as @xmath49 .
we shall address the wide variety of non - local statistically homogeneous and isotropic sources @xcite ) for which @xmath50 @xmath51 denotes the power spectrum of the source and @xmath52 is the spectral degree of coherence @xcite .
a special particular case of these sources are those thermal and blackbodies widely studied .
on inserting eq .
( 2 ) into ( 1 ) and taking the statistical homogeneity of the source into account , one obtains the total force on the particle . for these sources only the force along the @xmath53-axis is different from zero .
we consider mutual incoherence between the particle electric and magnetic induced dipoles , i.e. , @xmath54 @xcite . @xmath55 and @xmath56 will denote the total forces due to the above mentioned contributions of the primary fluctuating source in @xmath2 and to the secondary source field from the particle induced dipoles , respectively .
we study the effect of the magnetodielectric properties of the particle in the near infrared .
this is a semiconductor sphere ; its anomalous scattering properties have recently received a great deal of attention , both theoretically and experimentally @xcite . in particular , for each incident plane wave component its scattered intensity in the backscattering direction is zero , [ first _ kerker condition _ ( @xmath57 ) ] when @xmath58 is fulfilled . also for each of such plane wave components impinging the particle , the forwardly scattered intensity becomes close to a non - zero minimum [ second _ kerker condition _ ( k2 ) ] when @xmath59 . in both cases : @xmath60 @xcite .
thus , we address a si sphere of radius @xmath61 , the spectrum of the incident light being in the range of @xmath62 . at these frequencies
the total cross section of the particle is fully determined by the mie coefficients @xmath63 and @xmath64 @xcite , this justifies the use of eq .
( 1 ) .
we assume a gaussian degree of coherence of the source , therefore the correlation function reads @xmath65 @xmath66 , @xmath67 being the coherence length of the source and @xmath68 representing the normalized spectrum .
notice that for @xmath69 , @xmath70 , then the source becomes _ @xmath71-correlated _ , like in e.g. a thermal one following the fluctuation - dissipation theorem @xcite .
the source considered here will have an au interface at @xmath24 , hence supporting surface plasmons polaritons ( spps ) in the spectral range under consideration , and thus enhancing the near field forces @xcite .
after performing all the integrations of the form of eq .
( 3 ) for the primary source and for the induced dipoles , ( a long but straightforward work , some of whose details are shown in the supplementary information ) , one sees that @xmath72 .
this will be relevant when we discuss the particle kerker conditions . ) , magnetic ( @xmath73 ) and interference force ( @xmath74 ) from a @xmath71-correlated source .
the first horizontal row shows the part of the force due to the field from the fluctuating primary source at @xmath24 , [ first term in eq .
( 2 ) ] .
the insets exhibit the behavior of the electric , magnetic and electric - magnetic interaction force components , respectively , normalized to @xmath75 .
the second horizontal row represents the force from the secondary source constituted by the particle induced dipoles , [ second and third terms in eq .
( 2 ) ] ] fig .
1 shows the logarithm of the force .
this representation aims to clarifying its drastic changes of sign .
all the results of this paper will be normalized to the spectrum of the source in order to see the relative weight of each force component .
the first horizontal row shows the force @xmath55 due to the field impinging from the primary statistical source at @xmath24 .
the second horizontal row represents the force @xmath56 from the secondary source constituted by the electric and magnetic dipoles induced on the particle .
the fluctuating source coherence length @xmath67 is first assumed to be zero .
the inset shows the behavior of the polarizability for the range of wavelengths considered .
this helps to understand the color plots . in figs .
1(a ) and 1(b ) we see a line separating the gradient and scattering forces . for a statistically homogeneous source , the gradient force ( proportional to @xmath76 )
is governed uniquely by the evanescent modes and is negative for a particle with @xmath77 @xcite , hence , it exponentially decays with the distance z to the source . on the other hand ,
the scattering force ( proportional to @xmath78 ) is positive , i.e. pushing , and constant for any @xmath79 .
as the wavelength grows , @xmath80 , [ see the inset in fig .
1(a ) ] , the gradient force dominates even at distances larger than @xmath81 , where the evanescent modes do not contribute .
this is a remarkable new feature of this kind of particles .
fig .
1 ( c ) represents the force component @xmath82 due to interference between the particle induced electric and magnetic dipoles . in the near field
this is almost repulsive for any wavelength , however , at distances larger than the wavelength , where the poynting vector @xmath83 is independent of the distance , we have a zone where this force is negative ( the arrow indicates that zone ) .
this kind of action is known as a _ pulling _ force @xcite , and its interest has increased in the last years . this last plot shows the relevant role of the magnetodielectric behavior of these particles in this respect , although in this latter specific case when the two other components : electric and magnetic , are added this pulling effect becomes very small , ( the electric - magnetic dipole interference force at @xmath84 and @xmath85 is one order of magnitude less than either @xmath86 or @xmath87 ) , however by manipulating the fluctuating source , a suitable power of the emitted electromagnetic field is obtained @xcite so that a tractor light field appears , even in the far zone . concerning the force @xmath88 fom the particle induced dipoles , we observe in the second row of fig .
1 that this force exponentially decays with the distance z to the primary source plane @xmath24 , and its sign depends on that of the particle polarizability ; nevertheless , the oscillating behavior of the green function due to propagating plane wave components manifests in this force .
we also observe that it is six orders of magnitude larger than its counterpart @xmath55 from the primary fluctuating source , at least at subwavelength distances @xmath53 .
we shall later discuss this . to get a deeper understanding , fig .
2 represents @xmath56 for some selected wavelengths and for two different source coherence lengths : @xmath89 and @xmath90 . for an statistically homogeneous source ,
the relationship between the electric and magnetic cross - spectral density tensors is @xcite @xmath91 hence , in the near field , when the first or the second kerker condition holds , one has @xmath92 and @xmath93 , however , in the far zone @xmath92 for any value of @xmath79 .
for the si particle addressed , the kerker conditions are fullfilled at @xmath94 and @xmath95 , ( see figs .
2(a ) and 2(b ) and @xcite ) .
we can also see in the inset of fig .
1(b ) , that in the range of @xmath96 there is a peak in the imaginary part of @xmath15 which predominates over all other @xmath97 parts .
the black - dashed - dot line in fig .
2 represents the force in this peak . in that case ,
the magnetic force @xmath98 is one order of magnitude larger than @xmath99 and @xmath100 , hence the total force on the particle is governed by this magnetic force .
this effect , due to the dielectric particle magnetic response to the light field , constitutes one of the main results of this paper . ,
@xmath87 and @xmath101 versus the distance from the plane of the source ( in wavelength units ) for some values of the wavelength ( in @xmath102 ) .
the two kerker conditions occur at @xmath103 , ( k1 ) , and @xmath104 , ( k2 ) , respectively . ]
we now address the influence of the coherence length of the source .
this will establish the differences between the mechanical action of partially correlated sources and that from e.g. thermal sources and blackbodies .
the spectral degree of coherence in @xmath105space is @xmath106 $ ] , hence , it acts a low - pass filter being maximum for @xmath89 ( i.e. when the source is @xmath71-correlated ) .
because of this fact , the evanescent modes present two such filters : the first is due to the own nature of these evanescent modes while the second stems from the spatial coherence of the source .
the shape of figs .
2(d)-(f ) is similar to that of figs .
2(a)-(c ) , shifted by a distance @xmath107 , therefore for @xmath108 the force is solely due to the non - conservative ( scattering ) force and to the interference force @xmath101 , which becomes constant and positive or negative depending on the wavelength .
it is worth pointing out that the price paid on increasing the coherence length is expensive , because at the same time there is a reduction of the force strength by various orders of magnitude [ cf .
e.g. the forces shown in figs . 2 ( a ) and 2 ( d ) ] . , @xmath109 and @xmath110 versus distance @xmath53 ( in units of wavelength ) from the exit plane @xmath24 of the source for different values of the wavelength ( in @xmath102 ) .
the two kerker conditions are fulfilled at @xmath103 , ( k1 ) , and @xmath104 , ( k2 ) , respectively . ] once we understood the role of the coherence length , we turn our study to its influence on the force @xmath88 induced by the secondary source , namely by the particle induced dipoles .
fig .
3 represents @xmath56 for the same wavelengths as in fig .
2 .
the magnitude of the force in the near - field @xmath111 is much larger than in fig .
2 , thus , the effect of the mechanical action @xmath88 of the field emitted by the particle induced dipoles substantially dominates over that @xmath112 of the field that is due solely to the stochastic source . nevertheless , as the distance @xmath53 grows , all the fastly oscillating components , electric , magnetic and that of interference , of this force @xmath88 rapidly tend to zero , and hence is the force @xmath112 from the primary source the one that dominates . as follows from the calculation of @xmath113 and @xmath114 , the cross spectral density tensor of the electric and magnetic dipoles
now are not equal ; therefore , and although at first sight it could seem that similar relationships between the electric and magnetic forces , in kerker conditions , are fulfilled like for @xmath112 from the primary source , in fact they are not .
the role of the coherence length in this case is exactly the same as in fig .
1 ; the magnitude of the force decreases as @xmath67 grows .

– A dog who was mistakenly flown to Japan is back with his family in Kansas. The 10-year-old German shepherd, named Irgo, arrived at a Wichita airport Thursday night after a flight on a private plane from Japan, the AP reports. Kara Swindle and her two children were flying on United Airlines from Oregon to Kansas City, Mo., earlier this week during a move to Wichita, Kan. When they went to pick up Irgo, however, they instead were given a Great Dane. "They had no idea where [Irgo] was," Swindle tells CNN. "I burst into tears instantly." Swindle says Irgo had no sustenance or anything to drink during his 16-hour journey; he also had to go without the medication he was taking for an ear infection during his worldwide travels. He was checked out in Japan, though, and deemed healthy enough to fly back home. United said in a statement that the dogs were somehow put on the wrong flights during a connecting flight in Denver. "We apologize for this mistake and are following up with the vendor kennel where they were kept overnight to understand what happened," the airline said in a statement. Irgo was reunited with Swindle and her family Thursday at the airport (video of the happy reunion can be see at Digg). Swindle wouldn't say whether she's considering legal action, per the AP. But she was pleased with United's efforts to return Irgo. She said the dog seemed healthy and happy to be home. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Story highlights United Airlines apologizes for the mix-up Irgo is headed back home today (CNN) United Airlines wrongly shipped a Kansas-bound pet dog to Japan, the second embarrassment this week for the airline and a "nightmare" for the Swindle family -- who are moving from Oregon to Wichita with their beloved pet, a 10-year-old German shepherd named Irgo. The ordeal began Tuesday when Kara Swindle went to retrieve Irgo at a United Airlines cargo facility in Kansas City. But Irgo was nowhere to be seen. In his place, she found a Great Dane that was supposed to be en route to Japan. The dogs had both been in Denver, where they were to catch connecting flights. Panic quickly set in over the fate of Irgo, who the Swindles adopted when he was 4 years old. "They had no idea where the dog was," Swindle said. "I burst into tears instantly because this has just all been a whirlwind. They didn't know (where Irgo was) until 2:30 a.m. on Wednesday when the plane landed in Japan." Swindle said Irgo -- who was flying for the first time -- had no water or food on the 16-plus hours flight to Japan. Irgo is suffering from an ear infection and hasn't had medication in three days, she said. Read More ||||| WICHITA, Kan.

– A night of fun between two best friends at a sleepover turned deadly when one allegedly accidentally shot the other in the head with a pellet gun, McAlester News-Capital reports. Justin Ingle, 12, died Saturday at a Tulsa, Okla., hospital of head trauma, reports the Raw Story. The incident happened Friday night in the town of Bache. Police say the boy was hit in the temple from only a few feet away by a pellet traveling at 1,250 feet per second, according to KOTV. "This juvenile has got to live with this the rest of his life," the sheriff says, referring to the boy—not being named due to his age—who allegedly fired the shot. He told authorities he didn't think the pellet gun was loaded. An investigation is ongoing, but so far, authorities believe the shooting was accidental—"horseplay," as the sheriff calls it. "You don’t think of death when you think of pellet or BB guns," the sheriff says, but "this is not your Red Rider standard gun." In the past, it was "not unusual to lose an eye, or something of that effect with a BB gun," but these days, new models are much more powerful and can kill, though such deaths are uncommon, he explains.

Pittsburgh County Sheriff Joel Kerns told Tulsa’s Channel 6 News that the accidental killing took place on Friday night. “This young man was actually his best friend,” said Kerns. “They wasn’t arguing, they wasn’t fighting. We think it’s just horseplay.” The boy who shot the other boy told authorities that he thought the gun was unloaded. The victim’s mother rushed the boy to McAlester Regional Medical Center. Kerns explained that she felt she could transport him to the hospital faster than an ambulance could reach the house, which he described as being in a “semi-remote area.” On Saturday, the victim was transferred to a hospital in Tulsa where he died of head trauma. Kerns said that such deaths are uncommon with B.B. and pellet guns, but occasionally they occur. “It’s not unusual to lose an eye, or something of that effect with a B.B. gun, but you don’t think of death when you think of pellet or B.B. guns,” he said. “It just tears you up, and there’s another person always affected by this, it ain’t just the victim and his family, this juvenile has got to live with this the rest of his life,” the sheriff said. The incident, Kerns told Channel 6, underscores the need for anyone who handles a gun, even pellet and B.B. guns, should take a gun safety course.

– Demolition experts successfully destroyed a 173-foot silo in the town of Vordingborg, Denmark, on Friday. Unfortunately, they also wrecked the adjacent cultural center after the demolition went spectacularly wrong, the Guardian reports.

– When Charlie Sheen returns to your TV screen, he'll be playing a character originated by Jack Nicholson. His new show will be based on the Nicholson-Adam Sandler comedy Anger Management, TMZ reports, but Sheen's character won't stick strictly to that script: Instead, he'll play an ex-jock with his own anger issues who becomes an anger management counselor in the criminal justice system. Joe Roth, who produced the 2003 film and owns the screenplay, has worked with Sheen in the past (on Major League, Young Guns, and other films) and is pushing this project forward, but the deal with Lionsgate is not quite finalized and no network has agreed to air the show yet.

Ever since the guy trashed his Plaza hotel room, chased a naked porn actress around, and went on a crazyfest that got him fired from Two and a Half Men, everyone from Jimmy Fallon to John Stamos has mercilessly mocked him. What else is there to make fun of? I mean, really! Do we need to give Sheen any more attention than we already have? Comedy Central says it will air a roast of Sheen at the hands of some of its nastiest and most biting comics. Conveniently, the show will run right after the Two and a Half Men premiere -- the first episode without Charlie, whose character will be killed off. I'm just wondering where these comedians are going to get any original material. We've already seen Fallon's spoof commercial for an imaginary cologne called "Winning," where he does a hilarious impression of Sheen in a cloud of cigarette smoke. We've heard Denis Leary compare him to Moammar Kaddafi and Sarah Silverman say she'd think she was a genius too if she hung out with 20-year-old porn stars. Then there was Ricky Gervais' line in his Golden Globes speech: "Get ready for a night of partying and heavy drinking. Or as Charlie Sheen calls it -- breakfast!" They could do one-liners about how Sheen's new TV show will be based on the movie Anger Management and his character will be just like Jack Nicholson's. But that will already have been beaten to a pulp on late-night TV by the time their turn comes. The Sheen roast has already happened, people. Actually, it's been done to death.

– The Los Angeles County coroner has ruled that a man who fell 53 stories to his death at the Wilshire Grand Center skyscraper construction site on St. Patrick's Day intentionally killed himself, the AP reports. The father of 36-year-old Joseph Sabbatino earlier told KABC-TV that his son struggled with depression and had been prescribed medication, and on Thursday, Coroner's Lt. David Smith confirmed the death was a suicide. It was only the second day on the job as an electrician for Sabbatino, who fell from the building and onto a moving car, the Los Angeles Times reports. "I moved over and then 'boom!' my car just shook," Donna Crockett, the driver of that car, told KTLA. "And I'm sitting there and I'm like, 'Oh God, somebody hit me.' ... When I opened up the door, his boot was lying next to my car." Crockett wasn't injured. Turner Construction, which manages the site, says Sabbatino didn't have any reason to be above the third floor and that he had completed a "comprehensive safety orientation" the day before he died, per the Times. Witnesses say he had taken off his hard hat before falling and that he didn't have on a tethered safety harness. The 53rd level had a barricade to prevent falls, and the company issued a statement saying the incident was not work-related. The builder gave nearly 1,000 workers a day off after the incident. Crockett calls the experience "traumatic" and told KTLA her heart breaks for Sabbatino's family and that she hopes to one day give his wife a hug.

– The Chicago Blackhawks may have crushed the hearts of Boston Bruins fans when they won the Stanley Cup, but they definitely don't want any hard feelings. The team took out a full-page ad in the Boston Globe today thanking the city for its hospitality. "As impressed as we were by … the Boston Bruins on the ice, we were deeply touched by what happened off the ice," the ad reads. "Rarely have we experienced the hospitality you afforded us throughout the playoff series." In a subtle nod to the Boston Marathon bombing and resulting solidarity meme, the letter closes by saying, "Like the rest of the world, Chicagoans have been reminded in recent days of Boston's strength. Please know we tip our hat to your city's big heart and gracious spirit."

An image in a supplemental section Wednesday called “Hawkeytown” shows a hand tearing out the Bruins logo from that page with the legend “Yeah, not right now we’re not.” “It’s kind of clever but we’re pretty sure there’s an unspoken ‘no takeseys-backsies’ rule in place when it comes to heartfelt tributes to the victims of a national tragedy,” Eric Randall writes in Boston Magazine. “No disrespect to Boston was intended, and we regret that some readers were offended,” a Tribune spokesperson told Randall in an email. “Our original sentiments of support for Boston and the victims of the recent bombing still stand.” Here’s the Tribune’s sports page from April 16: And here’s a longer explanation of how it came together.

– Waffle House is home to more than wacky crime and weird behavior. It also has an equally weird Twitter feed—that is, if you consider it strange for corporate entities to solicit our opinions on current events, Jon Bershad writes on Mediaite. Waffle House's recent tweets about Whitney Houston and Super Bowl ads filled Bershad with faux enthusiasm: "Oh, man!" he writes. "I should totally ask them what their thoughts on the GOP primaries are. What does Waffle House think about the tensions with Iran?" "Wait, that’s more of a global issue. I should probably tweet the International House of Pancakes to talk about that." Bershan has long been amazed that "human cattle ...

If there are people out there dumb enough to actively sign up to read McDonald’s PR messages (329,000 Twitter followers!) or “like” a soda brand on Facebook (who wouldn’t want to be friends with Pepsi?), why shouldn’t corporations exploit them? However, these attempts to get people to “engage” with brands sometimes get a little weird. Take, for example, today’s tweet from Waffle House in which they just wanted to know what people thought of Whitney Houston’s funeral. You know, like giant restaurant chains do. The tweet was noticed by comedian and Twitter provocateur extraordinaire Joe Mande who declared Waffle House’s message a “hall of fame corporate tweet.” I can’t ague with that. I remember the ancient times at the beginning of Twitter when I thought it was weird that people were following celebrities they don’t know in real life. I mean, why should I give a crap what Ashton Kutcher is up to right now? That thinking just seems quaint now that we live in a world where I can discuss every possible cultural moment with a waffle restaurant. Oh, man! I should totally ask them what their thoughts on the GOP primaries are. What does Waffle House think about the tensions with Iran? Wait, that’s more of a global issue. I should probably tweet the International House of Pancakes to talk about that. A couple decades from now, after the corporations have complete control of the planet and people go to war over brand names instead of countries, I’m going to look back and say that my favorite part of their bloody take over was when they hired 20 somethings to make them look friendly by using goofy hashtags.

18.0pt the role of the isoscalar hyperon @xmath0 in probing the density dependence of the nuclear symmetry energy is studied in multi-@xmath0 hypernuclei , hyperon - rich matter and neutron stars in relativistic models .
relationships between the properties of three types of objects and the neutron thickness in @xmath1pb are established with respect to the isoscalar - isovector coupling that modifies the density dependence of the symmetry energy .
the exotic isotopes far from the neutron drip line can be stabilized by filling in considerable @xmath0 hyperons .
the difference of the binding energy of multi-@xmath0 hypernuclei from different models is attributed to different symmetry energies .
the isovector potential together with the neutron thickness in multi-@xmath0 hypernuclei investigated is very sensitive to the isoscalar - isovector coupling .
the large sensitivity of the @xmath0 hyperon fraction to the isoscalar - isovector coupling occurs at about @xmath2 in beta equilibrated hyperon - rich matter . in neutron stars with hyperonization ,
an on - off effect with respect to the isoscalar - isovector coupling exists for the neutron star radius .

many factors that influence the isovector potential directly or indirectly can modify the behavior of the density dependence of the symmetry energy .
recently the density dependence of the symmetry energy has been extensively explored through the inclusion of the isoscalar - isovector coupling terms in relativistic mean field ( rmf ) models@xcite .
these new terms enable one modify the neutron skin of heavy nuclei without changing the charge radius and a variety of ground - state properties that are well constrained experimentally .
on the other hand , the charge density distributions for some light exotic nuclei near drip lines that are not determined yet are sensitive to the isoscalar - isovector couplings@xcite .
hypernuclei that are produced through strangeness transfer reactions mostly contain only one hyperon , and just a few double @xmath0 hypernuclear events were observed@xcite . through heavy - ion collisions it may possibly create an environment which is favorable to the formation of metastable exotic multihypernuclear objects ( memos ) such as multi-@xmath0 hypernuclei .
schaffner et.al . showed that multi-@xmath0 hypernuclei were more strongly bound than normal nuclei using the rmf model@xcite .
recently , jevorsek et.al .
set limits on the existence and properties of exotic objects such as strangelets and memos , and provided limits as low as @xmath4 for m / z up to 120 through a reanalysis of related data@xcite . in bulk matter
, strangeness can be formed by virtue of the strong interaction , and hyperons may be important constituents of neutron stars .
many important effects of hyperonization in neutron stars have been found in the past ( for a review , see@xcite ) .
for instance , hyperonization reduces the maximum mass of neutron stars as much as 3/4@xmath5@xcite .
schaffner et.al . found that a phase transition to hyperon matter may even possibly occur in neutron stars@xcite . in this work , it is the aim to constrain the density dependence of the symmetry energy through the investigation of properties of multi-@xmath0 hypernuclei , hyperon - rich matter and neutron stars with hyperonization .
we will perform the investigation in rmf models considering the isoscalar - isovector coupling terms that soften the symmetry energy at large densities .
the modification in memos and hyperon - rich matter due to the isoscalar - isovector couplings is usually considered to be small due to the relatively weak meson - hyperon coupling . as pointed out in refs.@xcite that the memos may reach a very high baryon density ( @xmath6 ) like strangelets . in hyperon - rich matter
, the appearance of @xmath0 hyperons occurs at about twice normal density .
since the higher density relates to the larger isoscalar potentials ( or fields ) , the isoscalar - isovector couplings will induce large modifications . in hyperon - rich matter
, we will focus on the relation between the @xmath0 fraction and the isoscalar - isovector coupling .
as the determination of properties of neutron stars with hyperonization needs the equation of state of hyperon - rich matter , we may search for the observable consequence relating to the density dependence of the symmetry energy . as examples of memos
, we will consider multi-@xmath0 hypernuclei based on the ca isotope far off the normal neutron drip line at the fixed isospin . in this way
, we can observe the extension of the drip line , and explore the density dependence of the symmetry energy by shifting the isoscalar field . in this study , additional strange mesons @xmath7
( i.e. @xmath8 , 975mev ) and @xmath9 ( 1020mev ) are also included in rmf models to describe the strong @xmath10 attraction as in refs.@xcite .

we study chemically equilibrated and charge neutral hyperon - rich matter including baryons @xmath28 and leptons @xmath29 without @xmath30 hyperons , since @xmath30 hyperons do not appear@xcite according to the fact that the isoscalar potential changes sign in the nuclear interior and becomes repulsive based on recent @xmath31 atomic data @xcite . for the finite system ,
we consider the spherical case .
the solution detail can be referred to refs.@xcite , and it is not repeated here .
the pairing correlation of nucleons in nuclei is considered in the bcs approximation as in refs.@xcite .
we perform calculations with the nl3 @xcite and s271@xcite parameter sets .
these two models share the same binding energy per nucleon ( 16.24mev ) and incompressibility ( 271mev ) at the same fermi momentum @xmath32@xmath33 ( @xmath34@xmath35 ) .
the symmetry energy is given by@xcite a_4=+ [ sym]with @xmath36 and @xmath37 .
the density dependence of the symmetry energy is different between two models because of different @xmath38 , @xmath39 and @xmath40 ( @xmath41 for the nl3 and @xmath42 for the s271 ) .
the @xmath25 and @xmath43 meson couplings to the hyperons are given by the su(3 ) relations : @xmath44 , @xmath45 and @xmath46 .
the @xmath47 meson coupling to the hyperons is determined by reasonable hyperon potentials in nuclear matter : @xmath48mev and @xmath49mev .
the coupling constants @xmath50 and @xmath51 are taken to satisfy the su(6 ) relation : @xmath52 , and the @xmath53 is fitted to improve the @xmath10 interaction matrix element @xmath54@xcite . in ref.@xcite , the @xmath53 is taken in a range close to the @xmath55 .
we take the ratio of the scalar coupling constant to be @xmath56 in nl3 with a potential for the @xmath0 hyperon in @xmath57 matter @xmath58mev . in s271 ,
the same potential is taken to obtain the ratio @xmath59 . in this way
, the @xmath54 of @xmath60be is improved from 0.38 mev to 2.2 mev in nl3 , and from 0.2 mev to 3.9 mev in s271 , much close to the extracted value @xmath61 mev .
the @xmath62 is determined by the @xmath57 hyperon potential in @xmath57 matter @xmath63mev@xcite .
the @xmath64 tensor coupling is vanishing , and the @xmath65 tensor coupling is small but adjusted to simulate the vanishing spin - orbit splitting for the @xmath0 hyperon observed in @xmath66o . for simplicity
, we perform calculations for various isoscalar - isovector coupling @xmath67 s , and the @xmath68 is set as zero . for a given coupling @xmath67
, we follow ref.@xcite to readjust the @xmath69 coupling constant @xmath38 so as to keep an average symmetry energy fixed as 25.7 at @xmath70 @xmath33 . in doing so
, it was found in ref.@xcite that the binding energy of @xmath1pb is nearly unchanged for various @xmath67 s .
below , we will see how the total binding energy of multi-@xmath0 hypernuclei is modified by the @xmath67 .
the binding energy per baryon for various @xmath71ca+@xmath0 s systems is displayed in fig.[fig1 ] .
metastable minima appears with the rise of the @xmath0 hyperon number @xmath72 .
the additional @xmath10 attraction , simulated by the strange mesons , produces much larger binding energy at larger @xmath73 and shifts the minima outwards .
the difference of binding energies of multi-@xmath0 hypernuclei in nl3 and in s271 enlarges explicitly with the rise of @xmath72 .
since both models share the same saturation properties and take the same potential for the @xmath0 hyperon , this enlargement is attributed to the different density dependence of the symmetry energy . with the rise of @xmath72 , the central density of multi-@xmath0 hypernuclei increases .
for instance , the central density in @xmath71ca@xmath74 is about 1.43@xmath75 in nl3 which is much larger than 1.06@xmath75 in @xmath71ca .
the more different symmetry energy at the larger density domain , shown in the inset in fig.[fig1 ] , thus accounts for the large difference of the binding energy at larger @xmath73 .
fig.[fig2 ] shows that the two - neutron separation energy of @xmath76ca+@xmath0 s systems increases from the negative to the positive with the rise of @xmath72 . as the @xmath72 increases , the nucleon potential is enhanced by the attraction between hyperons and nucleons , being able to fill in more neutrons under the continuum . the neutron drip line can thus be largely extended .
for instance , the drip line of ca isotope can be extended from the neutron number 50@xcite to 82 as long as about 50 @xmath0 s are filled in .
the dependence of the separation energy on the isoscalar - isovector coupling @xmath67 reduces approximately with the increase of @xmath72 . in refs.@xcite , a large class of memos
are constructed by adding multi - hyperons in stable nuclei , while here we aim at the extension of the neutron drip line by filling in @xmath0 hyperons in unstable isotopes . as multi-@xmath77 hypernuclei
may exert their roles in extending the neutron drip line and binding baryons more strongly than in normal nuclei , they will potentially influence the astrophysical nucleosynthesis and the abundances of elements . to search for multi-@xmath0 hypernuclei with the @xmath72 up to 50
is possible but certainly difficult@xcite . here
, we just devote ourselves to investigating the sensitivity of properties of such exotic systems to the density dependence of the symmetry energy .
the sensitivity of the total binding energy to the @xmath67 is different for various @xmath71ca+@xmath0 s systems . for @xmath71ca+@xmath0 s systems that are unstable against the neutron emission at small @xmath72 and unstable against the @xmath0 hyperon emission at very large @xmath72 ,
the total binding energies can be modified by as much as tens of mev for various @xmath67 s . for stable @xmath71ca+@xmath0 s systems
whose binding energies are situated on or very close to the minima , shown in fig.[fig1 ] , the modification to the total binding energies by various @xmath67 s is quite small .
for instance , the total binding energy for @xmath71ca+50@xmath0 in nl3 is just modified by up to 2mev with various @xmath67 values .
a data to data correlation of the neutron thicknesses between @xmath1pb and stable multi-@xmath0 nuclei can be established as in refs.@xcite .
the neutron thickness of these stable multi-@xmath0 nuclei is very sensitive to the @xmath67 .
for instance , the uncertainty of the neutron thickness for @xmath71ca+40@xmath0 and @xmath71ca+50@xmath0 is about 3 times that for @xmath1pb .
the proton density distribution in these exotic system is also sensitive to the @xmath67 and one third of the uncertainty of the neutron thickness comes from the protons .
the large uncertainty of the neutron thickness is attributed to the addition of the @xmath0 hyperons , which will be elucidated below .
usually , one modifies the isospin dependent potential considering the shift of the isospin and the isovector field directly . here , we modify it by enhancing the isoscalar field ( @xmath25 field ) through filling in @xmath0 s without changing the isospin of the system , which is fulfilled by considering the isoscalar - isovector coupling . in fig.[fig4 ]
, the isovector potentials are displayed for @xmath71ca and @xmath71ca+@xmath78 in nl3 . in s271
, similar results for these two systems can be obtained .
the isovector potentials for various @xmath67 s in the exotic isotope are largely shifted by filling in considerable @xmath0 hyperons .
the uncertainty of the isovector potential against the @xmath67 in @xmath71ca is much larger in the larger radius region , compatible with the understanding that @xmath71ca is totally diffusive and unstable .
compared to results for @xmath71ca , the sensitivity of the isovector potential to the @xmath67 in @xmath71ca+@xmath78 is shifted to the central region , and at the large radius the convergence occurs , which is favored by the extension of the neutron drip line .
the results shown in fig.[fig4 ] for two exotic systems are related to different density profiles .
the central density in @xmath71ca+@xmath78 is about one third higher than that in @xmath71ca .
the deviation of the symmetry energy for various @xmath67 s enlarges with the rise of the density beyond the normal density or even much lower density@xcite . at the central region in @xmath71ca+@xmath78 ,
the isovector potential is more sensitive to the @xmath67 than that in @xmath71ca .
the isoscalar potential can also be shifted to a certain degree by the @xmath67 , whereas for the normal nuclei the shift is negligible .
the sensitivity of the isovector potential to the @xmath67 is responsible for the uncertainty of the neutron thickness .
the @xmath0 hyperon constituent is important in astrophysical bulk matter to explore the effects of the density dependence of the symmetry energy .
we plot the @xmath0 and @xmath79 fractions defined by @xmath80 in fig.[fig5 ] with the s271 based on a self - consistent calculation .
the large sensitivity of the hyperon fractions to the @xmath67 occurs at about @xmath2 where the @xmath0 hyperon starts to appear . since the density as high as @xmath2 is accessible through the heavy ion collisions with the colliding energy about 1gev per nucleon , the detection related to the hyperons , especially the @xmath0 s , in heavy ion collisions is helpful to probe the density dependence of the nuclear symmetry energy .
the starting density for the @xmath0 appearance is model dependent .
for instance , it is about 1.8@xmath81 in nl3 and 2.2@xmath81 in s271 . as shown in the inset in fig.[fig5 ] , a shift of the isovector potential starts to appear with the @xmath0 appearance , and the isovector potential differs more from that without hyperonization with the increase of the density . in multi-@xmath0
nuclei far from the normal drip line , the isovector potential is shifted by filling in @xmath0 s under the fixed isospin , while here the shift comes from the change of the isospin and the isoscalar field together . the convergent extent with respect to the @xmath67 exists for the hyperon fraction in the whole density domain
this indicates that it is favorable to include the isoscalar - isovector coupling terms for the model itself . at very high densities
, the convergence of hyperon fractions occurs .
this is attributed to the fact that the isospin is largely suppressed with the drop of the neutron fraction at high densities .
the isovector potential is thus small compared to the isoscalar potential , so that the isoscalar potential is little changed through the isoscalar - isovector coupling .
this implies that the hyperstars@xcite whose core is solely composed of hypermatter at high densities will be insensitive to the @xmath67 .
the large reduction of the maximum mass of neutron stars by hyperonization , firstly pointed out by glendenning ( see ref.@xcite and references therein ) , can be reproduced here . in nl3 ,
hyperonization in the core reduces the maximum neutron star mass by about 0.9@xmath5 from about 2.8@xmath5 , and by 0.75@xmath5 from about 2.4@xmath5 in s271 .
compared to models in which hyperons are absent , hyperonization in the neutron star whose mass is near the maximum mass increases the central baryon density by as much as 1@xmath81 in the region @xmath82 km . for a 1.4 solar - mass neutron star ,
the role of hyperonization is quite limited because of relative low core densities . using the oppenheimer - volkoff equations for bulk
matter in beta equilibrium , we thus investigate neutron stars with relative large masses : 1.8@xmath5 with the nl3 model and 1.62@xmath5 with the s271 model . in fig.[fig6 ] , the radii of neutron stars with respective masses in two models are displayed as a function of the neutron thickness for @xmath1pb .
the radius r of neutron star without hyperonization increases with the neutron thickness in @xmath1pb for a given parameter set , which is the same as in ref.@xcite . for neutron stars with hyperonization ,
the trend is similar , whereas the correlation between the r and the neutron thickness in @xmath1pb almost vanishes in a large region of the neutron thickness in @xmath1pb .
this property is consistent with the convergent extent shown in fig.[fig5 ] .
it indicates that for a neutron star with hyperonization the radius r nearly just depends on the on - off switch rather than concrete values of the isoscalar - isovector coupling in a given model .
an accurate measurement of the neutron radius for @xmath1pb at the jefferson laboratory@xcite determines the density dependence of the symmetry energy at low densities , as pointed out in ref.@xcite .
the measurement of the radius of the neutron star with hyperonization can discriminate two regions of the @xmath67 s to which the r is either very sensitive or insensitive at high densities .
various information through separate measurements may be combined together to constrain the isoscalar - isovector coupling that modifies the density dependence of the symmetry energy in the whole density region . in summary , we have studied the roles of the isoscalar @xmath0 hyperons in exploring the density dependence of the symmetry energy in multi-@xmath0 hypernuclei , hyperon - rich matter and neutron stars with rmf models .
relationships between the properties of three types of objects and the neutron thickness in @xmath1pb are established with respect to the isoscalar - isovector coupling that modifies the density dependence of the symmetry energy .
the exotic isotopes far from the neutron drip line can be stabilized by filling in considerable @xmath0 hyperons , and the neutron drip line is substantially extended outwards .
the difference of the binding energy of multi-@xmath0 hypernuclei from different models is attributed to different symmetry energies .
the isovector potential together with the neutron thickness in multi-@xmath0 hypernuclei situated on the new drip line that is far from the normal drip line is very sensitive to the isoscalar - isovector coupling . in beta
equilibrated hyperon - rich matter , we have investigated the sensitivity of the hyperon fractions to the isoscalar - isovector coupling based on the self - consistent calculation for hyperons and nucleons .
the large sensitivity of the @xmath0 hyperon fraction to the isoscalar - isovector coupling occurs at about @xmath2 .
the properties of neutron stars are investigated . an on - off effect with respect to the isoscalar - isovector coupling exists for the radius of neutron stars with hyperonization . besides the detection of @xmath0 hyperons in the heavy ion collisions ,
the measurements of the neutron star radius and neutron thickness in @xmath1pb could help set up the constraints on the density dependence of the symmetry energy . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | this work is partially supported by the national natural sciences foundation of china under grant no.10405031 .the author thanks prof .m. di toro for helpful discussions .50 h. a. bethe , rev .62 , 801 ( 1990 ) i. bombaci , in isospin physics in heavy - ion collisions at intermediate energies , edited by b.a.li and w. udo schrder ( nova science publishers , inc ., new york , 2001 ) , p35 a.w .steiner , m. prakash , j.m .lattimer , p.j .ellis , phys .( 2005 ) 325 b.a.brown , phys .85(2000)5296 b.a.li , phys .85(2000)4221 ; ibid.88(2002)192701 c.j.horowitz , j.piekarewicz , physlett.86(2001)5647 c.j.horowitz , j.piekarewicz , phys . rev .c64(2001)062802(r ) ; ibid , c66(2002)055803 b.g.todd , j.piekarewicz , phys . rev .c67(2003)044317 y.b .shen , et.al .phys.lett.b586(2004)225 w.z.jiang , y.l.zhao , phys .b617(2005)33 l.w.chen , v.greco , c.m.ko , b.a .li , phys .90(2003)162701 m. di toro , a. drago , t. gaitanos , v. greco , a. lavagno , nucl - th/0602052 j.carriere , c.j.horowitz , j.piekarewicz , astrophys .j 593(2003)463 w.z.jiang , y.l.zhao , z.y.zhu , s.f.shen , phys . rev .c72 ( 2005)024313 s.aoki , et al prog . theor . phys. 85(1991)1287 j.k.ahn , et al phys .87(2001)132504 j.k.takahashi , et al phys .87(2001)212502 j.schaffner , c. b.dover , a.gal , c.greiner , h.stcker , phys .71(1993)1328 j.schaffner , c.b.dover , a.gal , c.greiner , d.j .millener , and h.stcker , ann .235 ( 1994 ) 35 d.javorsek ii , e.fischbach and d.elmore,phys .d67(2003)034015 n.k.glendenning , phys.rept.342(2001)393 n.k .glendenning , astrophys .j. 293 ( 1985 ) 470 n.k .glendenning , s.a .moszkowski , phys .67 ( 1991 ) 2414 j.schaffner-bielich , m.hanauske , h.stcker , w.greiner , phys .89(2002)171101 j.schaffner-bielich , a.gal , phys .m.prakash , i.bombaci , m.prakasha , p.j .ellis , j.m .lattimer and r.knorren , phys .280(1997)1 j.mares,e.friedman , a.gal , and b.k.jennings , nucl .b.d.serot , j.d.walecka , adv .nucl . phys .16(1986)1 ; int.j.mod.phys .e6(1997)515 p.ring , prog . part .nucl . phys .37(1996)193 g.a.lalazissis , j.knig , p.ring , phys .j.meng , h. toki , j.y.zeng , s.q.zhang , and s.g.zhou , phys .c 65 ( 2002 ) 041302(r ) r.michaels , p.a.souder , g.m.urciuoli , spokespersons , jefferson laboratory experiment e-00 - 003 |

histochemical journals represent a traditional forum where methodological and technological improvements can be presented and validated in view of their applications to investigate not only cytology and histology in normal and diseased conditions but to test as well hypotheses on more basic issues for life sciences , such as comparative and evolutionary biology .
the earliest scientific journals on histochemistry began their publication in the first half of the 50s of the last century , and their readership did not probably change over the years ; rather , the authors interests may have progressively been changing as well as the main topics of their articles .
this hypothesis is discussed , based on the subjects of the article published in the first and last ten years in the european journal of histochemistry , as an example of old journal which started publication in 1954 , being since then the official organ of the italian society of histochemistry .
this survey confirmed that histochemistry has provided and still offers unique opportunities for studying the structure , chemical composition and function of cells and tissues in a wide variety of living organisms , especially when the topological distribution of specific molecular components has diagnostic or predictive significance , as it occurs in human and veterinary biology and pathology .
some subjects ( e.g. histochemistry applied to muscle cells or to mineralized tissues ) have recently become rather popular , whereas a wider application of the histochemical approach may be envisaged for plant cells and tissues . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | it is actually impossible to predict the future trends of histochemical research ( and consequently the subjects of the articles that will appear in histochemical journals ) ; this will essentially depend on the hot topics that will emerge in biology and biomedicine , as well as on the unpredictable development of novel instruments and technologies in the next years . the very small sample ( less than 800 articles ) considered in the present survey , however , confirms that histochemistry has provided and still offers unique opportunities for the study of structure , chemical composition and function of cells and tissues in a wide variety of living organisms , especially when the topological distribution of specific molecular components has diagnostic or predictive significance . consistently , it may be expected that human and veterinary biomedicine will represent , also in the future , the main application fields of histochemistry . the still rather large number of recent articles concerning basic biological investigations on lower vertebrates and invertebrates also suggests that histochemistry is the appropriate tool for drawing reliable correlations between microanatomy and physiology in tissues and organs from still poorly described organisms . through a comparative approach , histochemical evidence in parallel with molecular data on protein and dna will provide clues for elucidating the origin and evolution of cellular systems and physiological functions . a wide development of histochemical research will especially be possible in the field of plant biology , where the number of histochemical articles published has so far been relatively small : less than 400 articles may be found in the literature since the 50s of the last century , but about 200 have been published in the last ten years , suggesting that the histochemical approach is becoming increasingly attractive for plant biologists , too ( source : http://www.scirus.com/ and http://apps.isiknowledge.com ) . as a final observation , it is worth emphasizing that histochemical journals still represent the distinctive forum where methodological and technological improvements can be presented and validated in view of their applications to investigate not only cytology and histology in normal and diseased conditions but also to test hypotheses on more basic issues for life sciences , such as comparative and evolutionary biology . |

– There's stupid, there's extremely stupid, and then there's "cementing your head inside a microwave" stupid. Firefighters in Wolverhampton, England, say they were "seriously unimpressed" after five of them had to spend an hour dealing with a case of the latter Thursday, the BBC reports. The West Midlands Fire Service says a 22-year-old man it describes as a "YouTube prankster" and his friends poured several bags of a fast-hardening product into an unplugged microwave oven they were using as a mold around the man's head, which was protected by a plastic bag. Firefighters say that by the time they were called, the man's friends had been trying to free him for 90 minutes and had given him an air tube to help him breathe. Firefighters had to call a technical rescue team for help freeing the man, which involved taking apart the microwave and very carefully removing the cement, using a screwdriver. "As funny as this sounds, this young man could quite easily have suffocated or have been seriously injured," says Watch Commander Shaun Dakin, per the Telegraph. "All of the group involved were very apologetic, but this was clearly a call-out which might have prevented us from helping someone else in genuine, accidental need." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Firefighters were left "seriously unimpressed" after spending an hour freeing a YouTuber whose head had been "cemented" into a microwave.

West Midlands Fire Service said it took an hour to free the man after they were called to a house in Fordhouses, Wolverhampton. Friends had managed to feed an air tube into the 22-year-old's mouth to help him breathe, the service said. Watch Commander Shaun Dakin said the man "could quite easily have suffocated or have been seriously injured". Image copyright West Midlands Fire Service Image caption The fire service said the mixture had been poured around the man's head, which was protected by a plastic bag Mr Dakin said: "He and a group of friends had mixed seven bags of Polyfilla which they then poured around his head, which was protected by a plastic bag inside the microwave. "The oven was being used as a mould and wasn't plugged in. The mixture quickly set hard and, by the time we were called, they'd already been trying to free him for an hour and a half." Crews from the technical rescue team helped with taking the microwave apart, he added. "It took us nearly an hour to free him," added Mr Dakin. "All of the group involved were very apologetic, but this was clearly a call-out which might have prevented us from helping someone else in genuine, accidental need." |

– Sometimes, a simple plan works best if you're a criminal. And sometimes, that plan to shove $1,200 worth of meat down your pants and walk out of a supermarket undetected doesn't end so well. Police in Cortlandt, NY, have charged Gregory Rodriguez with grand larceny after accusing him of doing just that at the A&P where he works, reports the local Daily Voice. Rodriguez was actually arrested a day after the theft, and two burning questions sadly remain unanswered, according to the AP and the Journal News: How many trips did it take, and where's the meat now?

– A massive hurricane is moving north from Mexico's coast, and while it's not expected to hit land in the US, Southern California can expect some huge and possibly dangerous waves starting today and peaking tomorrow, authorities say. Hurricane Marie is weakening slightly, but some surf spots could see waves up to 25 feet high, and Los Angeles County beaches used to much smaller waves could see 15-footers, the Los Angeles Times reports. Strong rip currents are expected, and lifeguards warn that only the strongest, most experienced swimmers and surfers should go in the water. "The gist is, if you’re not a strong, strong aquatics person with fins, come down and watch from the safety of the shore," says the chief of the Newport Beach Lifeguard Battalion. In Mexico's Oaxaca state, some 10,000 homes were flooded or cut off by mudslides caused by Marie's rains, but the state government says the hurricane hasn't caused any deaths, the AP reports. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | MEXICO CITY (AP) — Hurricane Marie weakened into a Category 3 storm, but continued to kick up high swells along Mexico's northern Pacific coast and threatened to raise dangerous waves along the Southern California coast. This NOAA satellite image taken Monday, Aug. 25, 2014 at 02:00 AM EDT shows Hurricane Marie about 500 miles southwest of the Baja Peninsula. Marie is a very powerful storm with maximum winds measured... (Associated Press) The U.S. Hurricane Center in Miami said that by late Monday night Marie had sustained winds of up to 115 mph (185 kph) and was located about 505 miles (815 kilometers) southwest of the southern tip of Baja California. It said the storm was moving northwest at 13 mph (20 kph). Swells provoked by the storm were affecting much of Mexico's Pacific coast and the Hurricane Center warned of dangerous surf and rip current conditions. Hurricane-force winds extended up to 60 miles (95 kilometers) away from the storm's center, with tropical storm-force winds reaching out to 310 miles (500 kilometers). The hurricane center said Marie is expected to gradual weaken as it moves in a northwestwardly direction in the coming days, and could be downgraded to a tropical storm by Wednesday. The southern Pacific coast state of Oaxaca requested federal disaster relief after about 10,000 homes were either damaged, flooded or cut off by mudslides on the state's mountainous rural roads due to rains associated with Marie last week. One man was injured in a mudslide but there were no reported deaths, the state government said late Sunday. The government of Baja California Sur, closer to the hurricane's current location, said it would cancel some classes in the resort cities of Los Cabos as a precautionary measure. Swells generated by Marie are expected to reach Southern California by Tuesday, and could cause life-threatening surf and rip currents, as well as minor coastal flooding, the hurricane center in Miami said. ||||| Though Turner said that experienced swimmers and surfers — who hit the beach equipped with fins and an understanding of rip currents or other ocean hazards — would "probably be in pretty good shape," he said most people would be better off staying on the shore. |

– An Arizona man just wanted to reveal to the world the gender of his wife's soon-to-be-born baby. Instead, he set off a 47,000-acre wildfire that cost $8 million, reports the Arizona Daily Star. As a result, Dennis Dickey is now on the hook for $220,000 in penalties. Last year, the off-duty Border Patrol agent shot a target filled with the explosive Tannerite and colored powder—blue for boy, pink for girl—on a dry and windy day in Green Valley, Ariz. The ensuing blast started a brush fire that quickly spiraled out of control into what became known as the Sawmill Fire, according to a release from the US Attorney's Office in Arizona. It took about 800 firefighters close to a week to finally control it. "I feel absolutely horrible about it," the 37-year-old Dickey said in court last week. "It was probably one of the worst days of my life." Because it was an accident, Dickey wasn't charged with arson, and he is expected to keep his Border Control job. Luckily, the fire caused no injuries. Dickey had to immediately dip into his retirement fund to hand over $100,000, and he will make monthly payments of $500 for 20 years, reports the Sahuarita Sun. Dickey also will make a public-service announcement, presumably to warn other excited dads-to-be to skip the Tannerite. And, no, the coverage doesn't mention whether the Dickeys were having a boy or a girl. (This gender-reveal party didn't end so well, either.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | TUCSON, Ariz. – Today, Dennis Dickey, 37, of Tucson, Ariz., pleaded guilty to a misdemeanor violation of U.S. Forest Service regulations for igniting the Sawmill Fire, which caused more than $8 million worth of damage in April 2017. The Court scheduled a sentencing hearing for October 9, 2018. On April 23, 2017, near Green Valley, Ariz., U.S. Border Patrol Agent Dickey, who was off-duty at the time, ignited a fire that spread to Coronado National Forest, federal land administered by the U.S. Forest Service. This fire was referred to as the “Sawmill Fire.” Dickey started the fire by shooting a rifle at a target. Dickey had placed Tannerite, a highly explosive substance, inside the target, intending for it to detonate when shot by a high-velocity firearm bullet. Dickey fired shots at the Tannerite target, ultimately causing an explosion that started a fire that spread and resulted in damage to more than 45,000 acres of land managed by the State of Arizona, the U.S. Forest Service, the Bureau of Land Management, and various private landholders. Dickey immediately reported the fire to law enforcement, cooperated, and admitted that he started the fire. The total losses attributable to the fire, including suppression costs and damage to land and landholdings, totaled more than $8 million. In his plea agreement, Dickey agreed to a sentence of five years’ probation, and to make a public service announcement with the U.S. Forest Service concerning the cause of the Sawmill fire. Dickey agreed to pay restitution totaling $8,188,069. Dickey also agreed to make an initial payment of $100,000 toward the restitution judgment and monthly payments thereafter. The investigation in this case was conducted by the U.S. Forest Service. The prosecution was handled by the U.S. Attorney’s Office for the District of Arizona, Tucson.

– North Korea is working on a rocket so big that it makes the long-range Taepodong-2 missile it's preparing to test-launch look modest, South Korean government sources tell the Chosun Ilbo. Based on satellite images, they've determined that the North is working on a missile with a booster so large that it could fire more than 6,200 miles, meaning it would be capable of reaching the continental US. The officials aren't sure if the missile is functional, or "a life-sized mockup," but they suspect it will be unveiled either during a military parade on April 15, or during the army's April 25 centennial celebration. The North has around 10,000 missile experts with "considerable research skills," a source said in a separate report, and has spent some $3.1 billion on developing long-range ballistic missiles so far. For reference, South Korea has about 3,000 rocket experts total between the public and private sectors. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | North Korea is building a missile that is even bigger than the long-range missile it is preparing to launch this month, sources claimed Monday. South Korean and U.S. officials believe the North will unveil the missile at a military parade on April 15, nation founder Kim Il-sung's centenary, or on April 25, which marks the founding day of the North's Army. A government source here said U.S. reconnaissance satellites recently spotted a 40-m missile at a research and development facility in Pyongyang that is larger than the existing Taepodong-2 missile. "It remains uncertain whether this missile is functional or is just a life-sized mock-up," the official added. The rocket North Korea is preparing to launch soon is apparently 32 m long, the same as the Taepodong-2 that was launched in April 2009 with a maximum range of 6,700 km. The new missile is believed to be larger and equipped with a bigger booster that gives it a maximum range of more than 10,000 km, making it capable of reaching the continental U.S. ||||| There are about 10,000 people working on missiles in North Korea, three times more than in the South, a high-ranking South Korean military officer said Monday. He added they have "considerable research skills." North Korea started developing ballistic missiles in the mid-1970s. It produced Scud-Bs with a range of 300 km and Scud-Cs with a range of 500 km and deployed them along the frontline in the 1980s. The South Korean military estimates that North Korea has spent US$3.1 billion on developing and testing long-range ballistic missiles so far. The rocket North Korea plans to launch this month is likely to cost $850 million which, according to a South Korean official, is equivalent to a year’s food supply for 19 million people in the impoverished country. The South Korean military believes that even more money was spent on training missile specialists. In contr ast, South Korea has about 2,000 rocket propulsion experts in the civilian and public sectors excluding the military, some 200 of them at the Korea Aerospace Research Institute. A defense industry insider said, "Even counting the military workforce, the total capacity for missile research is far behind from North Korea's with a mere 3,000 experts." |

– A spate of odd news today concerning attacks in Russia: one on a dance floor, three in a cemetery, and another over a philosopher. Two 20-something men in line for beers at a festival in southern Russia, got in a heated dispute about 18th-century philosopher Immanuel Kant. The feud "deteriorated into a fistfight," police said today, and one of the men eventually shot the other in the head with an air gun—multiple times, the AP notes. The victim survived; the attacker could be in prison for a decade, RIA Novosti adds. Police arrested a 36-year-old woman after she allegedly stabbed another woman at a birthday party; the 21-year-old victim was apparently dancing with the attacker's boyfriend, RIA Novosti reports. The alleged attacker "took a knife, approached the dancing woman, and stabbed her twice," investigators say. The victim died in the hospital. A guilty verdict could mean 15 years in prison for the suspect. A man has been convicted of killing his mother, brother, and father in a cemetery. They were reportedly living in the graveyard after he evicted them, and when his mother accused him of the eviction, he hit her. His brother stepped in, and the man ended up stabbing both of them—and killing his father, who'd seen the attack.

The suspect became jealous when she saw her boyfriend dancing with a 21-year-old guest at a birthday party in a local cafe, a statement on the Krasnodar Territory investigative committee site said. She then “took a knife, approached the dancing woman and stabbed her twice,” the statement said. The 21-year-old was taken to hospital but later died from the injuries sustained, the statement said. If found guilty, the suspect faces up to 15 years in prison. ||||| ROSTOV-ON-DON, September 16 (RIA Novosti) – A “passionate argument” about 18th-century Enlightenment philosopher Immanuel Kant, renowned for his treatises on ethics, “deteriorated into a fistfight” between two men waiting in line for beer during an outdoor City Day event in the southern Russian metropolis of Rostov-on-Don, police said Monday. The argument ended when one of the debaters pulled out an air gun and shot the other in the head, local police said in a statement. The shooter then fled the scene but was later detained, police said. The other man’s wound was not critical, but he was hospitalized, the statement said, without disclosing any names. Local media said the men were in their late 20s. The attacker now faces up to a decade in prison for intentional infliction of serious bodily harm, police said. That sentence would give him time to more thoroughly study the works of Kant, who contemplated a universal law of morality. ||||| An argument in southern Russia over philosopher Immanuel Kant, the author of "Critique of Pure Reason," devolved into pure mayhem when one debater shot the other. The state news agency RIA Novosti on Monday cited police in the city of Rostov-on-Don as saying the argument took place in a small store and deteriorated into a fistfight. One participant pulled out a small nonlethal pistol and fired repeatedly. The victim was hospitalized with injuries that were not life-threatening. The weapon fired plastic bullets or blanks. Neither person was identified. It was not clear which of Kant's ideas may have triggered the violence. |

– "My wife and I have always dreamed our son will live in a place where pinball is legal," Steve Whikehart tells Fox 59. "After 40 years that dream will become a reality." The city council member sponsored legislation, signed into law Tuesday, that reversed a 61-year-old ban on pinball in Kokomo, Indiana, the Wall Street Journal reports. Back in 1955, the Kokomo city council determined pinball was gambling because it relied on chance, not skill, and banned it. According to news accounts at the time, pinball games "tend against peace and good order, encourage vice and immorality, and constitute a nuisance," and wives were upset their husbands were spending all their money on pinball. Anyone found violating the ban faced jail time and a fine. But in 2016, most people didn't know about the ban and officials couldn't find any records of people being cited for breaking it. “I’ve been serving beer and wine legally out of my record store, and having illegal pinball games,” says Mike Wilson, owner of American Dream Hi-Fi. “It’s funny.” On Tuesday, Mayor Greg Goodnight signed the new pinball-legalizing bill into law on top of one of American Dream's pinball machines, the Kokomo Tribune reports. "I was reflecting that ever since I was a young boy, I played the silver ball," Goodnight paraphrased. "From Southway up to Morgan Street, I think I played them all." Police chief Rob Baker, the only person in city hall who hadn't violated the ban, then got the first game. (A major California city recently made pinball legal after an 80-year ban.) | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Please enable Javascript to watch this video KOKOMO, Ind. – For many decades, the pings and bells of pinball machines could be heard in arcades and pizza parlors across the United States. However, the popular activity was outlawed in one central Indiana city. Why? Because it was a game of chance, not skill, and therefor considered gambling. The pinball prohibition in Kokomo stretches back decades, according to the Kokomo Tribune. Kokomo’s Common Council unanimously voted to ban pinball machines back in July 1955. At the time of the ban, it is estimated that there were 103 pinball machines in the city. According to an editorial published in the Kokomo Tribune, wives had long complained about the games and were very pleased with the ban because their husbands would spend their entire paychecks playing pinball. Punishment for owning or operating a pinball machine was a fine of up to $300 and six months in jail, the Kokomo Tribune reports. The ordinance also gave police the power to impound any operating pinball machine they encountered. Over 60 years later, the ban has still not been lifted. However, the city council is hoping to change that and vote to repeal the ban during a meeting on December 12. Council member Steve Whikehart is sponsoring the ordinance. "Obviously pinball machines are not a high mark on the police department’s, city council, or city administrations radar,” said Whikehart. The ban hasn’t been enforced in quite some time, and frankly, most people are unaware that it actually exists. "My wife and I have always dreamed our son will live in a place where pinball is legal. After 40 years that dream will become a reality,” Whikehart jokingly told FOX59. ||||| Kokomo, IN (46901) Today Snow this evening will taper off and give way to cloudy skies late. Low 6F.

– White House strategist Steve Bannon granted the New York Times an interview this week, and the main topic appears to have been how much he hates the New York Times and the rest of the news media. "The media should be embarrassed and humiliated and keep its mouth shut and just listen for a while," the former Breitbart chair said. "I want you to quote this. The media here is the opposition party. They don't understand this country. They still do not understand why Donald Trump is the president of the United States." He said the media had gotten the election "dead wrong," making it a "humiliating defeat that they will never wash away, that will always be there." Bannon—who jokingly referred to himself as Darth Vader—described unspecified editors and reporters as "outright activists of the Clinton campaign," telling the Times: "That's why you have no power. You were humiliated." He staunchly defended new White House press secretary Sean Spicer, saying it was a "badge of honor" to have the media question his integrity. "The media has zero integrity, zero intelligence, and no hard work," Bannon said. At CNN, Jake Tapper's response to Bannon's request to shut up was a simple "No," while the ACLU tweeted that it will see the Trump administration in court if it tries to shut the media up. Erik Wemple at the Washington Post wrote that since Bannon "helmed a campaign heavy on deceit, division, and cynicism, we don't want any praise from his likes." | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | “The elite media got it dead wrong, 100 percent dead wrong,” Mr. Bannon said of the election, calling it “a humiliating defeat that they will never wash away, that will always be there.” “The mainstream media has not fired or terminated anyone associated with following our campaign,” Mr. Bannon said. “Look at the Twitter feeds of those people: They were outright activists of the Clinton campaign.” (He did not name specific reporters or editors.) “That’s why you have no power,” he added. “You were humiliated.” Mr. Bannon spoke in blunt but calm tones, peppered with profanity, and humorously referred to himself as “Darth Vader.” He said, with ironic relish, that Mr. Trump was elected by a surge of support from “the working-class hobbits and deplorables.” The conversation was initiated by Mr. Bannon to offer praise for Mr. Spicer, who has been criticized this week for making false claims at the White House podium about attendance at Mr. Trump’s inaugural, for calling reporters dishonest and lecturing them about what stories to write, and for failing to disavow Mr. Trump’s lie about widespread voter fraud in the election. Asked if he was concerned that Mr. Spicer had lost credibility with the news media, Mr. Bannon chortled. “Are you kidding me?” he said. “We think that’s a badge of honor. ‘Questioning his integrity’ — are you kidding me? The media has zero integrity, zero intelligence, and no hard work.” “You’re the opposition party,” he said. “Not the Democratic Party. You’re the opposition party. The media’s the opposition party.” Journalists reacted with alarm and defiance to Mr. Bannon’s comments. “What country are we living in?” Christiane Amanpour, the CNN correspondent, wrote on Twitter. “We are not the opposition,’’ Stephen Engelberg, editor in chief of the nonprofit news organization ProPublica, wrote in an email. “We are part of an essential function in any democracy.” He added that ProPublica had no intention of “shutting up in response to this or any other president’s demand.” ||||| 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.

we investigate the possible corrections to the linear regge trajectories for the light - quark meson sector by matching two - point correlators of quark currents to the operator product expansion .
we find that the allowed modifications to the linear behavior must decrease rapidly with the principal quantum number . after fitting the lightest states in each channel and certain low - energy constants the whole spectrum for meson masses and residues
is obtained in a satisfactory agreement with phenomenology . the perturbative corrections to our results
are discussed .
the observed masses squared of mesons with given quantum numbers form linear trajectories @xcite depending on the number of radial excitation @xmath0 .
this is a strong indication that qcd admits an effective string description , as this type of spectrum is characteristic e.g. of the bosonic string . in the bosonic string model
the slope of all trajectories must be equal since this quantity is proportional to the string tension depending on gluedynamics only .
however , there exist sizeable deviations from the string picture . in the present analysis we examine possible corrections to the linear trajectories in the vector ( v ) , axial - vector ( a ) , scalar ( s ) , and pseudoscalar ( p ) channels @xcite .
our method is based on the consideration of the two - point correlators of v , a , s , p quark currents in the large-@xmath1 limit of qcd @xcite . on the one hand , by virtue of confinement
they are saturated by an infinite set of narrow meson resonances , that is , they can be represented by the sum of related meson poles in euclidean space : @xmath2 expressing the quark - hadron duality@xcite . here @xmath3 ; @xmath4 .
further we denote @xmath5 . on the other hand ,
their high - energy asymptotics is provided by the perturbation theory and the operator product expansion ( ope ) with condensates @xcite .
matching these two approaches results in the chiral symmetry restoration sum rules representing a set of constraints on meson mass parameters @xcite .
we performed the further analysis in the chiral limit and firstly in the leading order of perturbation theory .
let us consider the linear ansatz for the meson mass spectra with a non - linear correction @xmath6 : @xmath7 the last term in eq .
( [ acor1 ] ) signifies a possible deviation from the string picture in qcd .
the condition of convergence for the generalized weinberg sum rules @xcite imposes the equality of slopes and a falloff of non - linear correction .
the asymptotic freedom leads to the relation between residues and masses : @xmath8 .
our analysis showed that the analytical structure of the ope admits , however , exponentially small deviations from this relation ( in contrast to to @xcite ) , @xmath9 with certain constants @xmath10 and @xmath11 to be fitted .
it is plausible to suppose that , for masses , the dynamics under these exponentially small corrections is governed mostly by gluons and thereby does not depend on flavor .
thus , we keep the exponent @xmath12 the same for all channels . for the same reason we regard @xmath13 as independent of parity . in tables 1 and 2
we show an example of numerical fits resulting from our approach where in the s , p - channels two possibilities are considered : @xmath14-meson belongs to the radial regge trajectory ( @xmath14-in ) and does not ( @xmath14-out ) .
the inputs general for all tables ( if any ) are : @xmath15 , @xmath16 , @xmath17 , @xmath18 , @xmath19 , @xmath20 .
the units are : @xmath21 , @xmath22 , @xmath23 mev ; @xmath24 mev@xmath25 ; @xmath26 , @xmath27 , @xmath28 mev@xmath29 .
let us discuss the impact of running coupling constant at next - to - leading order of perturbation theory .
we have in this case the contribution to the imaginary part of correlator which is related to the full correlator through the dispersion relation . in the large-@xmath1 limit for the vector and axial - vector case
this leads to : @xmath30 we perform summation in eq . by applying the euler - maclaurin summation formula
this provides smoothness of this expression .
finally we obtain the relation : @xmath31 eq .
can be approximated by finite differences .
for the first two states this reads : @xmath32 substituting experimental values @xcite into eq .
one arrives at the estimate : @xmath33 in a good agreement with the phenomenology . in order to reproduce the running coupling behaviour in eq .
one should accept the following ansatz for the residues : @xmath34 however this ansatz introduces into the ope the additional terms @xmath35 ( and powers of these terms ) which are absent in the standart ope .
thus ansatz must be improved .
this problem is under our studies now .
let us summarize the results of our analysis : + * 1 ) * the convergence of the generalized weinberg sum rules requires the universality of slopes and intercepts for parity conjugated trajectories .
+ * 2 ) * the matching to the ope can not be achieved by a simple linear parameterization of the mass spectrum , the linear trajectory ansatz .
there must exist deviations from the linear trajectory ansatz triggered by chiral symmetry breaking .
these deviations must decrease at least exponentially with @xmath0 .
+ * 3 ) * for heavy states , the d - wave vector mesons have to decouple from asymptotic sum rules .
this fact implies the exponential ( or faster ) decreasing the corresponding decay constants @xmath36 .
+ * 4 ) * our results seem to exclude a light @xmath37 particle as a quarkonium state and rather favor the non - linear realization of chiral symmetry with the lightest scalar of mass @xmath38 gev , its chiral partner being the @xmath39 .
+ * 5 ) * in our approach the quantities @xmath40 and @xmath41 are obtained , in satisfactory agreement with the phenomenology .
+ * 6 ) * perturbative corrections can be systematically treated making , nevertheless , small effects on the fits presented . | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | this work is supported by rfbr , grant 05 - 02 - 17477 , grant ur 02.01.299 and infn , grant is / pi13 .work of s. a. and d. e. is partially supported by cyt fpa , grant 2004 - 04582-c02 - 01 and by cirit gc , grant 2001sgr-00065 .9 a. bramon , e. etim and m. greco , _ phys .lett . _ * b41 * , 609 ( 1972 ) ; m. greco , _ nucl .phys . _ * b63 * , 398 ( 1973 ) ; j. j. sakurai , _ phys . lett . _ * b46 * , 207 ( 1973 ) .a. v. anisovich , v. v. anisovich and a. v. sarantsev , _ phys .rev . _ * d62 * , 051502 ( 2000 ) .s. s. afonin , a. a. andrianov , v. a. andrianov and d. espriu , _ jhep _ * 04 * , 039 ( 2004 ) .g. t hooft , _ nucl ._ * b72 * , 461 ( 1974 ) ; e. witten , _ nucl .* b160 * , 57 ( 1979 ) .m. shifman , hep - ph/0009131 ; hep - ph/0507246 . m. a. shifman , a. i. vainstein and v. i. zakharov , _ nucl. phys . _ * b147 * , 385 , 448 ( 1979 ) .a. a. andrianov and v. a. andrianov , hep - ph/9705364 ; hep - ph/9911383;a .a. andrianov , d. espriu and r. tarrach , _ nucl ._ * b533 * , 429 ( 1998 ) .m. golterman and s. peris , _ jhep _ * 01 * , 028 ( 2001 ) . s. r. beane , _ phys . rev . _ * d64 * , 116010 ( 2001 ) .a. simonov , _ phys ._ * 65 * , 135 ( 2002 ) .particle date group ( s. eidelman _ et al ._ ) , _ phys . lett . _ * b592 * , 1 ( 2004 ) . |

– North Korea has its own version of Netflix, apparently. Citing local media, the BBC reports that state broadcaster KCTV has unveiled a set-top box called Manbang that connects to state-controlled intranet and allows viewers to watch, on demand, five TV channels, a number of documentaries "about the leadership," and English or Russian language-learning material. However, experts say most North Koreans don't actually have connectivity to the service. The Memo notes that TV "is a novelty for many North Koreans," since interference from radio signals prevents many of them from getting a good signal, a problem Manbang is said to solve. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | North Korea’s isn’t exactly known for being high tech, its heavily-censored and restricted internet being a prime example. But now streaming video has finally reached the communist dictatorship with a state-sponsored version of Netflix. Read more: North Korea is trying to build the next Google Meet Manbang Don’t expect to see House of Cards or Orange is The New Black on North Korea’s Manbang (no, it’s not an adult website, it actually means ‘everywhere’ or ‘every direction’ in English), as the service is extremely limited and certainly doesn’t have ‘everything’. Manbang offers on-demand Russian and English language lessons, “documentary films about the leadership”, selected newspaper articles, and other content curated around the state’s wishes. Revealed by North Korea’s state Korea Central Television (KCTV) last week, Manbang is delivered by a specialised set-top box that also includes access to five television stations. ||||| Image copyright Getty Images A set-top box offering video-on-demand services has been unveiled by the state broadcaster KCTV in North Korea, according to local reports. The box, called Manbang, has been dubbed the country's version of Netflix in some reports. It connects to the state-controlled intranet and is said to enable viewers to search for and replay documentaries and watch five TV channels. KCTV said consumer demand for the device was high. However experts say that most North Koreans have no connectivity. "If a viewer wants to watch, for instance, an animal movie and sends a request to the equipment, it will show the relevant video to the viewer…this is two-way communications," said Kim Jong Min, head of the centre in charge of providing information and technology, according to NK News. The news site also reports that the on-demand content includes English and Russian language learning material. In May security researcher Doug Madory discovered a social network - resembling a crude clone of Facebook - on a North Korean internet address. It was not online for very long, especially once people started setting up spoof profiles, including one of North Korean leader Kim Jong-Un. "I don't believe it was intended to be accessible from outside North Korea," Mr Madory told the BBC. |

– Graduating seniors at Reynolds High School in Oregon collected their diplomas this week just two days after a fatal shooting at their school. And one of those seniors happens to be the older brother of 14-year-old victim Emilio Hoffman. In tribute, Joshua Mitchell wore his little brother's soccer jersey over his formal cap and gown—and he turned his back to the audience to raise his arms and flash them the No. 29 on stage, reports the Oregonian. His classmates stood and cheered, and the photographer who captured the emotional, unplanned scene writes about it here. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | Sometimes as a photojournalist, I find myself in uncomfortable situations. Such was the case as I photographed Joshua Mitchell at the Reynolds High School graduation ceremony Thursday night. Mitchell's brother, Emilio Hoffman, was killed Tuesday morning in a shooting at the school by fellow student Jared Padgett. To honor his brother at the ceremony, Mitchell wore Emilio's Reynolds Raiders soccer jersey over his graduation gown. I was one of a few photographers who had floor access during the ceremony. Before Mitchell walked the graduation line, I evaluated where I might position myself to best shoot his photo. I noticed that students weren't reacting to the crowd when they received their diplomas, but rather when they walked down a ramp toward assistant principal John Dixon. Based on this I opted for the left side of the ramp, but at the diploma exchange I found my view blocked so I quickly moved to the other side as Mitchell made his last handshake. It was then that Mitchell turned his back to the crowd, revealing Emilio's number 29, and raised his arms, a diploma and plaque in one hand and his other hand made into a fist. The discomfort came for me when he turned back and I could see the emotional intensity in his face. There I was, standing, in front of all the students and the friends and families in the audience, feeling a bit like an intruder in the moment. I quickly downloaded my camera cards into my laptop and sent the arms up photo first, feeling like it was THE moment and then followed with several pictures from the ramp walk and Mitchell's hug with Dixon. I woke up early this morning, wondering if I had violated Mitchell's moment. Only he can answer that. The photo of Mitchell turning back has been very popular on social media, with more than 900 retweets and thousands of Facebook likes. What do you think about the photo? I'd love to hear your thoughts in the comments section below. ||||| Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive.

– No sooner has Prince William begun a new job than cheap technology is out to ruin it for him: British tabloid journalists say they were able to track the man who's second in line to the throne as he made flights in his air ambulance using an app that goes for $3.99, reports the Independent citing the report in the Mail on Sunday. Reporters downloaded the flight-tracking Flightradar24 app—which blocks military flights, though not private air ambulance flights, from users—and say they received alerts every time William took to the skies over eastern England, raising what officials are calling a serious security risk. Says a former head of the Royalty Protection Squad: "You always have to be aware of the advance of technology—which this illustrates—and the ability of these terrorist groups to think outside the box. You always, always have to be one step ahead." William's helicopter is relatively slow and low-flying, notes the AP. Royal reps had no comment. | Make an abstract according to the given text content, only output the abstract content and nothing else. | [] | LONDON (AP) — Britain's Mail on Sunday says it has uncovered a major royal security breach by using an inexpensive app to track Prince William's air rescue ambulance while it is in the air. The paper said the 2.99 pound ($4.65) app allowed it to keep close track of William as he flew in his capacity as a private pilot with East Anglian Air Ambulance in eastern England. It published photos claiming to show William's helicopter landing and of the prince himself. The paper said Sunday that William's helicopter flies at low altitude at a relatively slow speed. William's press office refused to comment on the report. The prince returned to work several weeks ago after paternity leave. ||||| A publicly available app which tracks air travel allows users to follow Prince William as he takes to the skies as an air ambulance pilot, it was claimed last night. There were warnings that ‘flightradar24’ app, which costs just £2.99 to download, could present a major security risk by providing precise details of his location. Reporters from the Mail On Sunday used the mobile phone software to see how the Prince could be tracked earlier this week and published photographs of him at work to show how the data had revealed where he had been. Military planes are concealed from the app’s users, but the same protection is not thought to be used for the air emergency services. The reporters said they received alerts every time his East Anglian Air Ambulance took off on a 999 call and landed. Dai Davies, the former head of the Met’s Royalty Protection Squad, told the newspaper: “This would give me cause for concern and solutions need to be found by those in charge of the Prince’s security. You always have to be aware of the advance of technology – which this illustrates – and the ability of these terrorist groups to think outside the box. You always, always have to be one step ahead.” Buckingham Palace and the Metropolitan police, which is responsible for royal protection, has not responded to the claims, nor have the app’s manufacturers. The Bond Aviation Group, which operates the East Anglian Air Ambulances, said it could not comment on security arrangements. |
