Abstract : A new absolute determination of the acceleration due to gravity was made at the former Geodatisches Institut Potsdam (since 1969 part of the Zentralinstitut Physik der Erde), using the reversible pendulum method. Beside essential theoretical fundamentals of the reversible pendulum method the publication presented here includes a detailed description of facts concerning the devices which have been used, their results and the way of interpretation. In addition the determinations of absolute gravity since the work of Kuhnen and Furtwangler are summarized and compared with the results from the recent reversible pendulum measurements performed at Potsdam.

In view of the current world market demand, "Face ID Recognition System" has developed to the highest level. In "Facial Recognition" field, the applications used are generally similar. Now the only thing we can change is how to adjust image resolution and how to speed up image processing. This paper adopts the existing rapid identification system architecture of "Paddle Paddle". It is an open source deep learning framework platform developed by Baidu. It contains a lot about lightweight architecture and lightweight networking. The "PP-Sin Tu" architecture is one of the lightweight identifications in "Paddle Paddle". It can use a few data to achieve the identification effect. The fast identification system and the accuracy of the identification effect, both performances are excellent, It's just that this architecture is not used for face recognition. Therefore, this paper wants to create a system that can quickly identify and achieved real-time identity by using a few identity data.


A convenient and effective way in the quantum double model to study anyons in a topological space with a tensor product structure is to create and braid anyons using ribbon operators connected to a common base site [A. Kitaev, Ann. Phys. (NY) 303, 2 (2003)]. We show how this scheme can be simulated in a physical system by constructing long ribbon operators connected to a base site that is placed far away. We describe how to move and braid anyons using these ribbon operators, and how to perform measurement on them. We also give the smallest scale of a system that is sufficient for proof-of-principle demonstration of our scheme.


5G and beyond networks will offer multiple communication modes including device-to-device and multi-hop cellular (or UE-to-network relay) communications. Several studies have shown that these modes can significantly improve the Quality of Service (QoS), the spectrum and energy efficiency, and the network capacity. Recent studies have demonstrated that further gains can be achieved when integrating demand-driven opportunistic networking into Multi-Hop Cellular Networks (MCN). In opportunistic MCN connections, devices can exploit the delay tolerance of many mobile data services to search for the most efficient connections between nodes. The availability of multiple communication modes requires mode selection schemes capable to decide the optimum mode for each transmission. Mode selection schemes have been previously proposed to account for the introduction of D2D and MCN. However, existing mode selection schemes cannot integrate opportunistic MCN connections into the selection process. This paper advances the state of the art by proposing the first mode selection scheme capable to integrate opportunistic MCN communications within 5G and beyond networks. The conducted analysis demonstrates the potential of opportunistic MCN communications, and the capability of the proposed mode selection scheme to select the most adequate communication mode.


Air breaths in undisturbed laboratory and pond groups of the aquatic African clawed frog, Xenopus laevis, Pipidae, are significantly clustered in time or synchronized in a manner similar to that of some air-breathing fishes. Breaths of isolated frogs occur at higher rates and were non-synchronous suggesting that a social component functions in the control of air-breathing behavior in this species. In several tests, disturbance (aerial, surface, and sub-surface) of pond or laboratory groups ofX. laevis increased the level of synchrony and temporarily decreased air-breathing rate. In X. laevis, air breathing may, if socially elicited, occur independently of the need for gas exchange or be postponed by disturbance.

Free jejunal flap transfer is common in head and neck reconstruction, but necrosis remains a complication. A 77-year-old man underwent total pharyngo-laryngo-esophagectomy, bilateral neck dissection, and free jejunal flap transfer. We anastomosed 3 arteries (facial, transverse cervical, and superior thyroid) and 1 vein (jejunal) because the recipient site's arterial status was poor. On day 2, ultrasonography and visualization revealed that the anastomosed vein was obstructed in the cranial jejunum but the remainder was viable. The region recovered by day 7 and the patient began oral intake on day 30. Ultrasonography revealed that the anastomosed jejunal vein showed no waveform, the facial and transverse cervical arteries showed arterial waveforms, and the superior thyroid artery showed a retrograde venous waveform. The flap had survived because the blood exited through the superior thyroid artery and vein. Thus, additional vascular and arterial anastomoses are options for free flap survival if the vascular status is poor.


was conrmed by computed tomography examination and coagulation test completed within 12 h after admission were enrolled. Patients with specic cardiovascular disease who used anticoagulants before admission were also excluded. Coagulation tests, which brinogen (Fib) and D-dimer were performed using a Sysmex CS5100 automatic coagulation analyzer and proprietary reagents. ABSTRACT Aim: To compare d dimer and brinogen as severity marker in staged COVID cases. Methodology: The present study was conducted in the department of Medicine at Chhatrapati Shivaji Subharti Hospital, Subharti Medical College, Meerut, UP. The study comprised of 100 subjects reported Covid positive during the June to December 2020. COVID-19 infection was conrmed by real-time reverse transcription polymerase chain reaction (RT-PCR) assay from nose and throat swab samples. Coagulation tests, which brinogen (Fib) and D-dimer were performed using a Sysmex CS5100 automatic coagulation analyzer (Japan) and proprietary reagents. Data was collected and subjected to statistical analysis using SPSS version 22. Results: According to logistic regression analysis, D-dimer (OR: 3.61, P<0.01) was associated more with severity of COVID as compared to brinogen (OR: 1.97, P=0.03), though both were signicantly associated with severity of COVID. Conclusion: Fibrinogen should be evaluated together with D-dimer levels in order to have more proper prognostic assumptions since its gradual decrease together with higher D-dimer levels have a role in diagnosing Covid-19 as early as possible.


The problem of noise generation due to the interaction between flows and plate edges is treated analytically. In uniform flow containing vorticity waves, two semi-infinite flat plates are placed with the trailing edge of one plate and leading edge of the other being tandemly situated a finite distance apart. This flow is considered to be a simplified model for self-excited tones such as edge tone and cavity noise. An approximate solution to the sound pressure is obtained by the Wiener-Hopf technique, and the calculated acoustic field shows the characteristics of the trailing edge noise and the leading edge noise. The sound pressure level varies with peaks and troughs as the wave number increases, especially in the region upstream from both edges, and these peaks show a frequency dependence similar to edge tones. Such a selective response mechanism will be explained by the phase relationship between vortex and sound.


false-positive rates of CNS involvement in systemic lupus erythematosus patients could be high when comparing systemic lupus erythematosus patients with a long history of steroid use with normal healthy subjects. Therefore, an age-matched control group with similar steroid history may be necessary when establishing a SPECT database for the clinical appli cation of 99mTc-HMPAO brain SPECT in systemic lupus erythematosus


"Theory" can still be experienced as something of an alien dimension in housing research. The Ž eld's strong tradition of applied policy-relevant research is too often seen as the antithesis of theory, with work either pidgeon-holed as theoretical or empirical. Theory is sometimes mistakenly understood as an abstract and often pretentious preamble that is simply tacked on to the beginning of an empirical study and that makes no contribution to its substance. Or even worse, theory can sometimes be seen as narcissistic; obtuse and abstract self-indulgence, with little or no relevance to the solution of practical problems of the sort that prompted Ruth Glass' jibe about verbal pollution. This is a pity, as empirical and theoretical are not polar opposites, but in a well-designed study grow out of each other and are mutually supportive. That is, each contributes to a clearer understanding of the other. Theory contextualises and provides the explanation of the empirical material, while the latter supports or does not support the hypotheses generated by the theory. In reality, all research has a theoretical dimension. The ideas that generated any research have their origins in – or relate in some way to – wider problems and issues both in the Ž eld itself and in one or more of the disciplines in which this or a similar problem has been addressed. Accomplishing such a mutually-beneŽ cial relationship is not as easy as might at Ž rst appear, and it is a major purpose of this journal to encourage such a re-integration. In this the journal has valuable and growing support. One sign of this was last year's European Network for Housing Research Conference held in Sweden in June 2000 with nearly 350 participants, which included a very successful Working Group on Housing and Theory chaired by Craig Gurney and Mark Bhatti. This resulted in the production of several high quality papers, a number of which have been revised and have been either already published in the journal or are forthcoming. It is particularly heartening to see that theoretically-informed work is taking root in housing research, and is less and less seen as pretentious pomposity. The linguistic turn in housing research continued its strong surge in 2000, re ected in a number of articles on social constructionism and discourse analysis. The journal also continues to extend the disciplinary boundaries of housing research. Amos Rapoport's article in Volume 17 represents a Ž rst for the journal in environmental psychology, a discipline with a housing focus that may be unfamiliar to many readers of traditional non-disciplinary housing studies, but that Rapoport has been in the forefront of developing. There are also articles on housing from the disciplines of economics and political philosophy, and a pathbreaking article questioning the taken-for-granted relationship between health and housing. A new development in Volume 17 has been the inclusion of two review articles, one in No. 1 on social constructionism by Keith Jacobs and Tony Manzi and one in No. 3 on discourse analysis by Annette Hastings. As review articles are not normally based on original research, they are subject to a simpliŽ ed Editorial Board review process. Review articles will hopefully become a frequent feature of the journal, and cover a wide range of issues. They may deal with a particular perspective or theory, or a method or epistemological issue. They could review the research in a particular region of the world, or on a particular policy or applied issue. Review articles can even deal with a lacuna, paradoxical as this might at Ž rst sight appear, indicating its limits and what relevant related literature there may be. Every housing researcher is an expert in one Ž eld or another, and more often than not in these days of specialisation the leading expert. The hope is that review articles will become a frequent, even perhaps a regular, feature of the journal. The other innovation that is being introduced is the Focus Article, the Ž rst of which appears in this issue by Taco Brandsen. Focus articles are not passed through the normal double-blind peer review. Instead, they are reviewed in print by a larger number of reviewers than are normally used in the pre-publication peer review process. These are chosen to cover a wide range of expertise in those specialisms that feature in the Focus Article, and are accompanied by an author response. Anyone who thinks their paper would make a suitable Focus Article should send a copy to the Editor.

This paper proposes hybrid approaches based on both feature level and score level fusion strategies to provide a robust recognition system against the distortions of individual modalities. In order to compare the proposed schemes, a virtual multimodal database is formed from FERET face and PolyU palmprint databases. The proposed hybrid systems concatenate features extracted by local and global feature extraction methods such as Local Binary Patterns, Log Gabor, Principal Component Analysis and Linear Discriminant Analysis. Match score level fusion is performed in order to show the effectiveness and accuracy of the proposed schemes. The experimental results based on these databases reported a significant improvement of the proposed schemes compared with unimodal systems and other multimodal face–palmprint fusion methods.


Welcome to the second part of the Special Issue of the American Journal of Health Education (AJHE) on Health Education and Health Promotion in College Settings. When the call for manuscripts went out, we could not have anticipated the number and quality of manuscripts that would be submitted. The first set appeared in Volume 48, No. 5 and is being continued with this issue. We hope this is an indication of the interest in and outstanding research that is being conducted with the college student population. As mentioned in the previous issue, college students are a unique population transitioning into adulthood and developing patterns of health behaviors that jeopardize their present and future health. Never before has the health of college students been as important. Additionally, as the cost of college increases, the link between health and academic success and retention becomes more relevant. Taking responsibility for one's health and developing healthy habits often emerge during the early adulthood age associated with the college years. Health behaviors learned and established in college can set individuals up for a lifetime of healthy living. It is important to take advantage of these formative years to ensure students continue healthy behaviors as they mature. The health needs of college students draw attention to the potential role and importance of health education and health promotion on college campuses. This issue features seven research articles and commentaries focusing on theory based behavior change and disease prevention interventions in college settings. Significant issues like HPV, mental illness, wellness, and disordered eating are addressed. Additionally, two articles feature technology and mobile phone health apps, which are commonly used by young adults who are digital natives. Addressing HPV infection in males is a significant public health issue. Chandrika Johnson and Roberta Ogletree examine male college student's knowledge and intention regarding the HPV vaccination using the Theory of Planned Behavior. Given that most HPV vaccines were initially geared towards women, there is limited data on vaccination among men. Their findings suggest there is serious work to be done on college campuses to increase the knowledge and acceptance of HPV vaccination among males. More students are coming to campus with significant health needs, including mental health challenges. Brandye D. Nobiling and Sherry Azadi Maykrantz use the Health Belief Model to investigate perceptions about mental illness and behaviors related to mental health service utilization, social support, and selfmedication among college students who may or may not have a history of mental illness. The results of their mixed methods study indicate the need for health education and health promotion efforts in college settings that encourage professional help seeking for mental health issues. College students are at risk for developing eating behaviors that promote obesity and eating disorders. Kelly A. Romano, Christina D. Colgary, and Amy Magnuson discusses, in their commentary, the role of dietary self-monitoring by means of eHealth/mHealth applications that incorporate nutritional food labeling in health behavior among college students. They advocate the use of eHealth/mHealth platforms to engage college students in nutrition related information across the different levels of the socio-ecological framework. The transition from adolescence to adulthood is a risky period for the development of obesity due to unhealthy diet and physical activity practices. Alessandra Sarcona, Laura Kovacs, Josephine Wright, and Christine Williams examined differences in eating behaviors, physical activity, and health-related lifestyle choices between users and non-users of mobile health apps among college students. The results suggest college students who are app users demonstrate healthier behaviors than non-app users. This has implications for the utilization of this type of


In a recent paper [Lopez JL. Asymptotic expansions of Mellin convolution integrals. SIAM Rev. 2008;50(2):275–293], we have presented a new, very general and simple method for deriving asymptotic expansions of for small x. In this paper we generalize that method to multi-dimensional integrals of the form . In this multi-dimensional case we require for f an extra condition not required in the one-dimensional case, namely, f must satisfy a certain homogeneity property in its variables. Watson's lemma for multiple integrals is obtained as a corollary. An asymptotic expansion of the Lauricella's function FA for large values of its variables is given as an illustration. The possible application of the method to study the asymptotic behaviour near the origin of double Mellin–Barnes type convolution integrals [Yakubovich SB. A constructive method for constructing integral convolutions. (Russian) Dokl Akad Nauk BSSR. 1990;34(7):588–591] is also indicated.


Context. The recent discovery of the binary black hole (BBH) merger event GW190521, between two black holes (BHs) of ≈ 100 M samp , in addition to other massive BBH merger events involving BHs within the pair-instability supernova (PSN) mass gap have sparked widespread debate on the origin of such extreme gravitational-wave (GW) events. GW190521 simultaneously triggers two critical questions: how BHs can appear within the 'forbidden' PSN gap and, if they do, how they get to participate in general- relativistic (GR) mergers. Aims. In this study, I investigate whether dynamical interactions in young massive clusters (YMCs) serve as a viable scenario for assembling PSN-gap BBH mergers. Methods. To that end, I explore a grid of 40 new evolutionary models of a representative YMC of initial mass and size M cl = 7 . 5 × 10 4 M samp ( N ≈ 1 . 28 × 10 5 ) and r h = 2pc, respectively. The model grid ranges over metallicity 0 . 0002 ≤ Z ≤ 0 . 02 and com-prises initial cluster configurations of King central concentration parameters W 0 = 7 and 9. In each model, all BH progenitor stars are initially in primordial binaries following observationally motivated distributions. All cluster models are evolved with the direct, relativistic N -body code NBODY7 , incorporating up-to-date remnant formation, BH natal spin, and GR merger recoil schemes. Results. Binary black hole mergers from these model cluster computations agree well with the masses and e ff ective spin parameters, χ e ff , of the events from the latest gravitational-wave transient catalogue (GWTC). In particular, GW190521-like, that is to say ≈ 200 M samp , low χ e ff events are produced via a dynamical merger among BHs derived from star-star merger products. GW190403_051519-like, that is PSN-gap, highly asymmetric, high χ e ff events result from mergers involving BHs that are spun up via matter accretion or a binary interaction. The resulting present-day, di ff erential intrinsic merger rate density, within the PSN gap, accommodates that from GWTC well. Conclusions. This study demonstrates that, subject to model uncertainties, the tandem of massive binary evolution and dynamical interactions in (cid:46) 100Myr-old, low metallicity YMCs in the Universe can plausibly produce GR mergers involving PSN-gap BHs and in rates consistent with that from up-to-date GW observations. Such clusters can produce extreme events similar to GW190521 and GW190403_051519. The upper limit of the models' GW190521-type event rate is within the corresponding LIGO-Virgo-KAGRA (LVK)-estimated rate limits, although the typical model rate lies below LVK's lower limit. The present YMC models yield a merger rate density of 0 − 3 . 8 × 10 − 2 yr − 1 Gpc − 3 for GW190521-type events. They produce GW190403_051519-like events at a rate within 0 − 1 . 6 × 10 − 1 yr − 1 Gpc − 3 and their total BBH-merger yield within the PSN gap is 0 − 8 . 4 × 10 − 1 yr − 1 Gpc − 3 .


Expression from the Bacillus subtilis nrg‐21 locus increases 26‐fold during nitrogen‐limited growth. The DNA corresponding to this locus was cloned and sequenced. The nucleotide sequence revealed a gene that could encode a protein with sequence similarity to the Escherichia coliγ‐aminobutyric acid (GABA) permease. A transposon insertion in this locus eliminated the uptake of GABA and severely inhibited the utilization of GABA as a nitrogen source. Primer extension analysis revealed that the B. subtilis gabP gene was transcribed from two overlapping promoters. Transcription from the P1 promoter was repressed during growth in the presence of amino acids. The product of the codY gene proved to be required for this repression. Transcription from the P2 promoter increased during nitrogen‐limited growth and was dependent upon the product of the tnrA gene. Deletion analysis revealed that activation of the P2 promoter during nitrogen‐limited growth requires a nucleotide sequence located upstream of its −35 region. Regulation of gabP expression by the CodY and TnrA regulatory systems, which respond to different physiological signals, allows for a wide range of gabP expression during growth on various nitrogen sources.


Objective To survey the prevalence, distribution of non-motor symptoms (NMS) in essential tremor (ET) and the relationship with disease severity and duration.Methods Fahn-Tolosa-Matin Tremor Rating Scale (TRS) was used to assess motor symptoms in 62 patients with ET.The Parkinson's disease (PD) NMS Questionnaire and T&T olfacmeter and Mini-mental State Examination (MMSE) were used to explore non-motor symptoms in ET patients.Results In ET, a range of NMS occurred across all disease stages.More than half patients (51.6%, 32/62) had olfactory dysfunction,significantly higher than the healthy control group (30.0%, 18/60, x~2=12.371, P<0.05).A third had hyposmia.16.1% had partial olfactory loss.Each ET patient had 5 different NMS on average.Seven NMS were more common in ET patients than in control, including remembering, olfactory dysfunction, intense vivid dreams, anhedonia, depression, anxiety, sleep disorders.The incidences of remembering, olfactory dysfunction,intense vivid dreams were 58.1% (36/62),51.6% (32/62),48.4% (30/62), ranked top 3 in ET patients.Olfaction had inverse correlation with age, while there was a negative correlation between NMS score and TRS score, gender, disease duration and weather to be treated.Conclusion Besides posture tremor and kinetic tremor,NMS occur in ET,and should be well recognized and treated.

Abstract : This report examines the estimation of bit error rates (BERs) in digital communications. Specifically, the authors will investigate recent work on using bounds to construct approximations for differential quaternary phase shift keying (DQPSK) transmission with Gray coding over an additive white Gaussian noise channel (AWGNC). In previous research, an estimate of this BER was constructed by averaging a lower and upper bound. The authors show that more direct methods can be applied to estimate the BER and that, in some cases, more accurate results can be obtained. The BER is a fundamental performance measure of a system, quantifying the reliability or integrity of a received signal. The instantaneous BER, for many practical communication systems, in particular, wireless communications systems, can be written as a function involving the standard Marcum Q-Function. This famous function has received much attention in the digital signal processing literature due to its intractability. This project involves estimation of the Marcum Q-Function. It should be of interest to both the radar and communications research communities. The authors examine bit error rate estimation in digital communications. They show that a method applied in a recent publication that uses bounds to estimate bit error rates can be improved considerably by using more direct techniques of estimation. The work is relevant to the long-range research efforts into radar detection issues associated with Task AIR 04/206, EWRD Support for AP-3C E/LM2022 Radar System. Although focusing on a communications application, the results transfer directly to the latter. The technique examined here will be useful for engineers and scientists looking for efficient and accurate approximations for intractable integrals.

The article is divided in two parts. The first one is about an ethics proposal based in principles in the world of professions. The principles, that constitute a theo- retical frame of reference for professional ethics, have been constructed during a long period, especially since the end of the Second World War, with the formulation and ap- proval of different codes that regulate the Medical Sciences research with human beings and the enormous influence that they have achieve in all the other knowledge areas. The second part is about the four basic principles agreed by experts in this thematic field and their application for the teaching profession.


A large number of top quarks will be produced at the Large Hadron Collider (LHC) during the Run II period. This will allow us to measure the rare processes from the top sector in great details. We present a study of top-quark pair production in association with a bottom-quark pair ($$t\bar tb\bar b$$) from fast simulations for the Compact Muon Solenoid (CMS) experiment. The differential distributions of $$t\bar tb\bar b$$ are compared with the top-quark pair production with two additional jets ($$t\bar tjj$$) and with the production in association with the Higgs ($$t\bar tH$$), where the Higgs decays to a bottom-quark pair. The significances of the $$t\bar tb\bar b$$ process in the dileptonic and the semileptonic decay modes are calculated with the data corresponding to an integrated luminosity of 10 fb-1, which is foreseen to be collected in the early Run II period. This study will provide an important input in searching for new physics beyond the standard model, as well as in searching for the $$t\bar tH$$ process where the Yukawa coupling with the top quark can be directly measured.

We applied Chunggangunbi-tang-gamibang to a 64 year-old male patient who had alcoholic liver cirrhosis with ascites. Chunggangunbi-tang-gamibang has been used to treat alcoholic liver disease and because of its beneficial effects. The patient with the disease expected several symptoms induced by Alcoholic liver cirrhosis, and we diagnosised differentiation of symptoms, using Chunggangunbi-tang-gamibang while removing dampness through diuresis and invigorating the spleen. After medication we could find remarkable effects on clinical symptoms, blood test results and abdomen ultrasonographic images. From this case, it is thought that using Chunggangunbi-tang-gamibang is very effective to improve the symptom of alcoholic liver cirrhosis with ascites.


Purpose – The aim is to understand the framework concerning the market area of competing tourist destinations and the relationship between the shape of the boundary line between markets and the factors that influence tourism to understand what is required to maintain a competitive tourist destination. Design, Methodology and Approach – The classical market area model is used, applying factors that influence the competitiveness of tourist destinations: cost to experience the tourist destination; the disutility/utility at the tourist destination; the strength of the destination's branding; transportation fee; the cost related to travel time; and the disutility/utility from transportation means. Findings – Using the above method, this research confirms how the shape of the boundary line between two competing tourist destinations is affected by these factors. This will enable tourist destinations to further develop its competitiveness by helping identify potential markets not yet captured by the tourist destination. This could assist, local governments, tourist related industries and organizations understand potential areas of investment. Originality of the research – The originality of this paper is applying the classical model of market used in economic theories to the tourism sector to understand the factors that influence competitiveness of a tourist destination.


Berlin was my last (of five) IFLA conferences as Secretary General. The first IFLA conference I attended was Brighton in 1987. I was very much in the background then, as I was. a member of staff of the host organization, the (British) Library Association. I had already been involved internationally having worked for five years in Papua New Guinea training library staff, and nearly made it to the IFLA conference in Manila in 1980, but in the end I was unable to raise the money. After Brighton, I have attended every IFLA conference except two, at first as part of the (British) LA's delegation and then, of course, as a member of IFLA staff. The IFLA conference, now entitled 'World Library and Information Congress', is a kaleidoscope of events taking place at the same place in the same time frame: satellite meetings, IFLA business meetings, caucuses, colourful opening session, plenary speakers, open sessions, cultural events, the trade exhibition, poster sessions, and library visits. Not to mention the informal networking and reunion of old friends that is such a feature of our annual


Recent advances in Natural Language Processing have led to powerful and sophisticated models like BERT (Bidirectional Encoder Representations from Transformers) that have bias. These models are mostly trained on text corpora that deviate in important ways from the text encountered by a chatbot in a problem-specific context. While a lot of research in the past has focused on measuring and mitigating bias with respect to protected attributes (stereotyping like gender, race, ethnicity, etc.), there is lack of research in model bias with respect to classification labels. We investigate whether a classification model hugely favors one class with respect to another. We introduce a bias evaluation method called directional pairwise class confusion bias that highlights the chatbot intent classification model's bias on pairs of classes. Finally, we also present two strategies to mitigate this bias using example biased pairs.


Twenty three children with coexistent duodenal ulcer and Helicobacter pylon infection were treated with either two weeks of amoxycillin (25 mg/kg/day) in addition to six weeks of cimetidine, or cimetidine alone. Endoscopy with antral and duodenal biopsies for urease test, microaerophilic culture, and histological studies were performed at entry, six weeks, 12 weeks, and at six months. Children with persistent H pylori infection at six weeks were given a further two weeks' course of amoxycillin. H pylon persisted in all children not receiving amoxycillin treatment but cleared in six of the 13 children (46%) treated with amoxycillin. With failure of H pylori clearance at six months, only two out of six (33%) ulcers had healed and 50% of patients had experienced ulcer recurrence. In contrast, when H pylori remained cleared all ulcers healed and no ulcer recurred. Persistent H pylon infection was associated with persistent gastritis and duodenitis despite endoscopic evidence of ulcer healing. Detection and eradication of H pylon deserves particular attention in the routine management of duodenal ulceration in children.

A Begomovirus isolate JH1 was obtained from Crassocephalum crepidioides showing yellow vein symptoms in Jinghong of Yunnan province, China. The complete sequence of Begomovirus DNA-A-like molecule of JH1 was determined to be 2745 nucleotides long. When compared with other begomoviruses, JH1 DNA-A has the highest nucleotide sequence identity (86.4%) with that of Tobacco curly shoot virus. Comparisons of individual encoded proteins with other begomoviruses show that different parts of JH1 DNA-A have different ancestors. The molecular data show that JH1 is a distinct Begomovirus species, for which the name Crassocephalum yellow vein virus is proposed.


lar series and provides these as examples to illustrate the shortcomings of American society and its institutions. This, in and of itself, would make the book ideal for a class related to media studies or popular culture. Simon takes a very creative approach by using The Sopranos as a vehicle to critique modern-day society. The author is critical of many social institutions, including the family, politics, law enforcement, big business, and the global economy. Simon is very creative in his approach. For example, he coins a term, "crimeogenic department store," to illustrate the types of crimes committed among street gangs, organized criminal syndicates, white-collar executives, and banks and major corporations. This elaborate metaphor provides the reader with an in-depth analysis of the relationships between each of the above groups, and it alone is worth the price of the book. Perhaps one of the most interesting aspects of this book is that Simon concludes his work by making an appeal for collective social action. It is obvious that he is disenchanted with the current state of affairs, and he urges readers to become involved in reshaping the American Dream. Simon contends that The Sopranos illustrates many of the shortcomings of postmodern society and suggests that people must become involved if there is to be any meaningful type of change. This is a truly interesting piece of work, and it has scholarly merit. It could be assigned as supplemental reading for virtually any criminal justice class, but it would also be appropriate for a history or political science course. I strongly recommend it; I finished it in one night.


In the present paper we investigate the condition whether the bounded domain B of C is a pseudo-conformal image of a circular domain, say C. Under the assumption that this is the case and that the invariant JB(zu z2; z\, z2) is not a constant, we characterize the center of a circular domain. This characterization is invariant with respect to pseudoconformal transformations. Assuming that B is a pseudoconformal image of a circular domain C and that there is in B one and only one point, say (ti, t2) which satisfies the conditions mentioned above, we determine the representative R(B\ U, t2) of B. If B is a pseudo-conformal image of a circular domain C and (ίi, t2) is the image in B of the center of C, then the representive R(B; tίf t2) is a circular domain. The pair of functions v, v mapping B onto R(B; U, t2) can be written explicitly in terms of the kernel function of B.


Introduction:The 2019 novel coronavirus disease (COVID-19) was initially identified in December 2019 in Wuhan, China. Following its spread across the globe within a matter of months, the World Health Organization classified COVID-19 as a pandemic.1 Its rapid transmission and high hospitalization rate have forced health professionals to drastically alter their practices in order to slow its proliferation. The rapid influx of COVID-19 related admissions in hospitals around the United States has led to a widespread shortage of crucial healthcare resources, particularly personal protective equipment (PPE), ventilators, and free ICU beds. Surgical procedures further deplete such resources in a time of acutely high need. Additionally, evidence has shown that healthcare workers may be particularly susceptible to infection from the causative pathogen, SARS-CoV-2, with roughly 20% of exposed professionals becoming infected in Italy.2Following these developments, the Centers for Disease Control and Prevention (CDC) recommended that all inpatient facilities postpone or cancel any elective surgeries.3 In the ensuing weeks, the American College of Surgeons and the American Academy of Otolaryngology-Head and Neck Surgery followed suit with this recommendation.4,5Furthermore, many hospitals and practices have opted to cancel in-person outpatient clinic visits, where patients oftentimes receive critical longitudinal care. Like other surgeons, otolaryngologists, and specifically head and neck surgical oncologists, have been deeply affected by these drastic measures. It is evident, however, that physicians must find ways to continue to monitor such patients' conditions or treat them in some aspect. The popularity and prevalence of telemedicine has grown rapidly during this pandemic as many physicians have sought ways to maintain a continuum of care with their patients.6 Such initiatives have previously been shown to decrease costs, decrease visit time, and lead to high patient satisfaction in surgical fields.7,8Within otolaryngology specifically, certain telehealth assessments have been shown to allow for quicker examinations without compromising the communication of crucial information from the patient to the physician, or vice versa.9 However, the rapid implementation of telehealth has been a relatively new phenomenon during the COVID-19 pandemic, meaning that physicians oftentimes have to learn how to optimize their virtual visits to maximize their efficiency and effectiveness. In otolaryngology, telemedicine has not been routinely used to evaluate patients, despite estimates that 62% of otolaryngology patients would be amenable to virtual appointments.10Thus, it may be difficult for physicians to anticipate barriers to their care during a telehealth visit. Based on the authors' experience, there exists a steep learning curve following the onset of such visits due to a variety of factors on both the patient's and physician's side.To our knowledge, there are no set guidelines or best practices for patients or head and neck cancer physicians conducting virtual visits. Drawing upon our experience, we aim to compile a set of guidelines for physicians and patients alike to navigate telehealth visits during the era of COVID-19. We also created a handout that can be distributed to patients prior to the visit, such that patients can familiarize themselves with general expectations and key examination steps that they may be asked to perform during the visit.


In present era, mental health has become one of the most neglected, yet critically important, factors of our overall well-being. A large number of people are affected by various types of mental illnesses and mental health disorders. Stress, anxiety, and depression are the most common disorders among children and adolescents in Sri Lanka, and their prevalence has increased over the years, likely to require immediate medical attention. In today's world, mobile phones and applications play an important role in everyone's life. With the rapid growth of mental illness, mental health-focused apps and websites have gradually increased globally in recent years. This study aims to develop a mobile application that will primarily serve Sri Lankans with mental health problems, helping them identify their levels of stress, anxiety, and depression (ADS) and receiving advice on how to deal with them. This app's main objective is to support those who are dealing with mental illnesses and raise awareness of them locally using machine learning and image processing techniques. It does this by serving as a constant reminder of how crucial mental health is and how much of an impact it has on daily life. The GSE Scale, DASS 21 scale has been used to find the users' mental health illness and the severity of each mental health illness such and Anxiety depression and stress. These methods are put to our mobile application using machine learning techniques such as Decision tree and Random Forest classifiers and uses image processing technologies, CNN machine learning algorithm to offer a variety of activities for reliving stress, depression, and anxiety,

The Stanford Positron-Electron Asymmetric Ring (SPEAR) consists o f a single ring of magnets threaded by an alum in ium vacuum chamber in which counter-rotating beams of electrons and positrons w ill circulate. A high luminosity is achieved by making the beams collide in one of two long »low-beta« interaction regions [1,2]. The ring is composed of the two matched low-beta regions connected by nearly c ir cular arcs of unequal length (Fig. 1). This configuration is derived from a previous Stanford Linear Accelerator design which used two intersecting asymmetric rings designed to produce higher luminosity in the energy range below 2 GeV than this project. The single ring described here is one of the two rings o f this previous design and allows high energy physics experiments to begin w ith a fac ility o f lower cost while preserving the option of adding the second ring at a later date.


(i) This article argues that the enforcement in New Cap Reinsurance Corporation v Grant of an Australian insolvency judgment is correct, although several aspects of the decision call for revision, in particular the unquestioning acceptance of Rubin v Eurofinance being binding. (ii) The Court of Appeal in New Cap Reinsurance Corporation v Grant missed a golden opportunity to depart from Rubin v Eurofinance. (iii) The Foreign Judgments (Reciprocal Enforcement) Act 1933 applies to foreign insolvency judgments. (iv) Section 426 of the Insolvency Act 1986 may ordinarily lead to enforcement of to foreign insolvency judgments. (v) The 1933 Act (where applicable) bars common law enforcement of foreign insolvency judgments. (vi) The 1933 Act should also bar enforcement of foreign insolvency judgments under s 426, and the Court of Appeal was mistaken in concluding otherwise.


Abstract We consider a unitary representation of a discrete countable abelian group on a separable Hilbert space which is associated to a cyclic generalized frame multiresolution analysis. We extend Robertson's theorem to apply to frames generated by the action of the group. Within this setup we use Stone's theorem and the theory of projection valued measures to analyze wandering frame collections. This yields a functional analytic method of constructing a wavelet from a generalized frame multiresolution analysis in terms of the frame scaling vectors. We then explicitly apply our results to the action of the integers given by translations on ${{L}^{2}}(\mathbb{R})$ .

The result can be a scientific foundation to design this kind of cartons correctly.


In recent times, light gauge cold-formed steel members have been used extensively in low rise buildings. However, they are susceptible to various buckling modes including local and distortional buckling. Fire safety design of building structures has received greater attention in recent times but mainly for heavier, hot-rolled steel members. The buckling behaviour of light gauge coldformed steel members under fire conditions is not well understood. The buckling effects associated with thin steel construction are significant and have to be taken into account in fire safety design. Therefore, a research project involving both experimental and finite element analyses was undertaken to investigate the distortional buckling behaviour of light gauge cold-formed steel compression members at elevated temperatures. Lipped channel sections made of various thicknesses and both low and high strength steels were designed to buckle distortionally, tested and analysed. The distortional buckling and ultimate strength results from experimental and finite element analyses were then compared with the predictions from the current design methods in order to assess their suitability under fire conditions. This paper presents the details of this investigation and the results.


The question of heating a tokamak plasma by means of electromagnetic waves in the ion cyclotron range of frequencies (ICRF) is considered in the perspective of large rf powers and in the low collisionality regime. In such a case, the quasilinear theory (QLT) is validated by the Hamiltonian dynamics of the wave–particle interaction which exceeds the threshold of the intrinsic stochasticity. The Hamiltonian dynamics is represented by the evolution of a set of three canonical action angle variables well adapted to the tokamak magnetic configuration. This approach allows derivation of the rf diffusion coefficient with very few assumptions. The distribution function of the resonant ions is written as a Fokker–Planck equation but the emphasis is put on the QL diffusion instead of on the usual diffusion induced by collisions. The Fokker–Planck equation is then given a variational form from which a solution is derived in the form of a semianalytical trial function of three parameters: the percentage of resonant p...


Those interested in the process of change in corrections need concepts which are helpful in understanding prison staff. The concept of a guard subculture is not consistent with existing research on correc tional officers. Instead, viewing officer support for procustodial norms as a shared misconception can provide direction for correctional leadership.


This study presents an innovative method for calibrating hydrological models in data limited basins using historical mean annual flow duration curves (FDC) and spatially distributed remote sensing evapotranspiration (ET). FDCs retrieved from historical observations could provide crucial information about river flow regime and hence could be considered as an option, particularly when observations are not available and /or intermittent, during model calibration and validation. Additionally, remote sensing ET offers a consistent spatially distributed and temporally varying information for model parameterization. Therefore, in this study, the Soil and Water Assessment Tool (SWAT) model for the Mara Basin (Kenya/Tanzania) has been calibrated using a multi-objective and multi-variable approach based on Borg multi-objective evolutionary algorithm (Borg MOEA). Two calibration experiments have been carried out – i) calibration to fit different portion of the mean annual FDC by minimizing the percent of bias for high flow volume, slope of the FDC and base flow volume and ii) including remote sensing ET to the calibration process in experiment i. The preliminary results revealed that calibrated model fairly reproduced the observed FDC indicating the promising potential of historical mean annual FDC for model calibration in poorly gauged and /or regulated basins. Furthermore, the use of remote sensing ET further improved the spatial pattern of the water balance components. The overall results show the potential of the method used in this study for hydrological model calibration in data scarce basins.


An instance of canine malignant lymphoma with some similarities to human Hodgkin's disease is described. Although the clinical data were all within normal limits, the histopathologic changes indicated that in many organs, the normal cell architecture was replaced by a pleomorphic cell population.


A 75-year-old man presented with pleuritic chest pain and right shoulder pain. A palpable right anterior chest wall mass was noted on physical examination. His past medical history was significant for testicular cancer treated with radiation therapy in 1974.

A computed tomography (CT) scan of the chest, performed without intravenous contrast due to renal insufficiency, revealed an 8-cm lobulated soft tissue mass arising from the right third anterior rib and involving the costal cartilage (Figure (Figure11). Scattered internal calcific deposits were present. It was uncertain if these represented chondroid matrix or destruction of calcified costal cartilage. The mass extended into the chest wall with elevation of the pectoralis muscles. Medially, the mass abutted the right anterior mediastinum. No additional osseous lesions or enlarged mediastinal or hilar nodes were seen. A few nonspecific 1- to 2-mm noncalcified pulmonary nodules were noted. CT of the abdomen and pelvis showed no evidence of metastatic disease.

Given the internal calcifications, the leading differential diagnostic consideration was chondrosarcoma; however, the classic "ring and arc" calcifications described in chondroid neoplasms were not definitively present on imaging. Metastasis was another consideration given the patient's history of testicular cancer; however, the location and appearance would be very atypical. The lesion appeared to arise from the chest wall and not the lung itself. Other considerations would include extramedullary plasmacytoma or lymphoma.

An ultrasound-guided needle biopsy of the lesion, prepared for rapid cytologic evaluation using hematoxylin and eosin, showed a myxoid chondroid matrix with chondrocytes present (Figure (Figure22). The subsequently prepared paraffin block from the core biopsy showed a similar chondroid matrix with increasing cellularity at the periphery of the nodule (Figure (Figure33). Though no distinctly atypical chondrocytes were seen, the cellularity was concerning for a possible low-grade chondrosarcoma, and the tumor was excised along with the second, third, and fourth ribs. Grossly, the tumor did not involve the lateral margins but was 12 mm from the inferior resection margin of the fourth rib and 3 mm from the periosteal soft tissue of the superior aspect of the second rib. The neoplasm clearly demonstrated cartilage synthesis, as well as areas of hemorrhage and necrosis (50% of total tumor volume) (Figure (Figure44).

Microscopically, the tumor showed features suggesting increasing histologic grade, such as areas with distinct marked hypercellularity, increasing nuclear size/atypia, and multinucleated cells (Figure (Figure55). However, the proliferation index, as demonstrated by MiB-1, was low, with most areas demonstrating 1% and focal areas demonstrating 5%. The tumor expanded the medullary cavity and in areas extended beyond the cortex, forming subpleural nodules posteriorly and involving the chest wall tissue anteriorly. The anterior chest wall surgical resection margin was focally involved by tumor. Extension through the pleural surface was not seen. Focal vascular invasion was present, with tumor grossly and microscopically surrounding and invading one blood vessel specifically. The tumor was considered grade 2.

Given the positive margin, radiation therapy was recommended. The patient received 3060 cGy of the planned 5940 cGy of radiation but could not complete the full course due to locoregional side effects. No additional therapy was recommended. A CT scan performed approximately 2 months after radiation therapy showed expected radiation changes and minimal pleural fluid without overt evidence of tumor recurrence. The patient is currently 4 months postradiation.


The Gender Development Index (GDI) is often considered a "gender-sensitive augment to the HDI". It addresses inequalities in life expectancy, education, and income among genders. The primary objective of this paper is to predict the GDI Values of various countries by using attributes that are highly correlated with the GDI, using Machine Learning Algorithms such as Linear Regression, Ridge Regression, and K Nearest Neighbours. We have also compared the prediction accuracy of these models to determine the optimal one and we found out that Linear Regression was the most accurate model with 97.30% accuracy. We can further use this model to improvise existing policies to reduce the gender gap in our society.


In this work a numerical model is proposed to simulate Friction Stir Welding (FSW) process in AA2024-T3 plates. This model included a softening model that account for the temperature history and the hardness distribution on a welded plate can thus be predicted. The validation of the model was performed using experimental measurements of the hardness in the plate cross-section. There is an acceptable prediction of the material softening in the Heat Affected Zone (HAZ) using the adopted model.


First part of this thesis was focused on optimization of chromatographic separation of
anthocyanins in the fruit of elderberry using isocratic and gradient elution. The mixture of
metanol and water with addition of formic acid was used as a mobile phase. Optimized
chromatographic separation coupled with UV detection was used for identification and
quantification of anthocyanins in extracts prepared from fruit of elderberry. Total
anthocyanins, total polyphenolics and antioxidant capacity were determined using different
spectrophotometric methods in all extracts. Results obtained by these methods were
statistically compared with total anthocyanins determinated by liquid chromatography.
Significant effect of treatment samples after collection (freezing/drying) was evaluated using
principal component analysis and analysis of variance. The best correlation of results was
observed between pH differential method and chromatographic determination.


The article examines how members of worker cooperatives articulated friendship as resistance against capitalist work relations. This elucidates relatively unexplored links between research on workplace friendships and resistance studies. Based on interviews with members from small Swedish worker co-ops, the analysis shows that the co-ops hinged their friendships on authenticity, but also valued friendship explicitly for its economic and political benefits. Yet, this ideal of authentic and equal friendships sat side by side with narratives of what the article calls 'friendship compliance'. This concept denotes how friendships may instil loyalty, reduce dissent and promote self-sacrifice. It is argued that while such compliance can be at odds with cooperative ideals, its expression in the worker co-ops studied here did not coincide with how the same mechanism has been described as operating in capitalist work organisations.


During March 1992, archeologists from the Western Archeological and Conservation Center conducted survey, detailed mapping, and feature recording at the missions of Guevavi and Calabazas in the Santa Cruz River Valley of southern Arizona. The most prominent features at the sites today are standing walls of Spanish-period churches. However, both sites also contain prehistoric and later historic components as well. The National Park Service is in the process of acquiring 8 acres at Guevavi from the Archaeological Conservancy and 22 acres at Calabazas from the Arizona Historical Society. These parcels will be managed as detached units of Tumacacori National Historical Park. The purpose of the archeological work was to provide information useful for the park's general management plan, which is being updated with the acquisition of these areas. Survey covered approximately 20 acres at Guevavi and 22 acres at Calabazas. Thirtysix features at Guevavi and 26 features at Calabazas were identified and recorded. The Guevavi features include remains of the church, convento, plaza, several compounds and other structures, adobe borrow pits, bedrock mortars , and canals. In addition, significant features associated with Guevavi, including a possible earlier church, were identified outside the future National Park Service parcel. The recorded features at Calabazas include remains of the church and compound, a rowhouse, other possible structural remains, a large depression, a ditch, and two bedrock mortar outcrops. Recommendations detailed in the report include: (1) acquisition of additional acreage at Guevavi to include all significant features related to the mission period; (2) backfilling of potholes and closure of roads to deter vandalism; and (3) archeological testing and surface collection to help mitigate the effects of increased site visitation.


Abstract A random vibration theory for the prediction of motion of clustered cylinders subjected to axial flow is presented. The response is assumed to stem from both mean flow effects and random pressure fluctuations in the turbulent boundary layer, the latter being required as an input to the analytical model; the measurement of wall-pressure fluctuation PSDs in the cluster is briefly described. The fluid coupling characteristics and turbulence-induced response of the system are illustrated for a four-cylinder. The inter-cylinder modal and spectral characteristics are displayed in terms of PSDs, coherence functions and CSDs for the lowest three groups of modes (24 modes in all). The evolution of these characteristics and of the amplitude of vibration with increasing flow velocity receive special attention.


The main purpose of this paper to ensure the chemical solution inside the reactor vessel maintained based on Raspberry Pi control system to keep the temperature constant. A steam-heated jacket envelops the reactor vessel, transferring heat from the steam into the chemical solution inside. The control system maintains a constant temperature by measuring the temperature of the reactor vessel, and throttling steam from a boiler to the steam jacket to add more or less heat as needed normally this action done by PLC or DCS, in this paper we are using Raspberry pi as temperature controller to monitor and control the temperature reactor.

To study the bilateral matching problem of new R&D institution-talent teams based on uncertain linguistic assessment information and multiple indicators-multiple talents, a cloud model regret theory-based information gathering method is proposed, and a bi-objective bilateral matching model based on single-indicator utility maximization and overall indicator utility maximization is constructed.. The method firstly constructs the demand indicators of new R&D institutions for talent teams, uses cloud data to characterize uncertain group linguistic assessment information, and converts cloud data into cloud perceived utility based on power function; secondly, calculates the indicator weights of each expert based on entropy power method, and secondly uses entropy power method to calculate comprehensive indicator weights, optimally solves objective expert weights based on the minimum variance of assessment information among experts, and integrates with subjective expert Again, based on regret theory, the cloud perceived utility of each talent under each index is converted into regret cloud perceived utility, and set with the index weights and expert weights into comprehensive cloud perceived utility; finally, a local-whole dual-objective bilateral matching model is constructed to obtain the matched talent team, and example analysis and method comparison are used to show that the method has feasibility and effectiveness.

Wheat were cultivated in hydroponic culture solution with 100 μmol/L Cu2+ and 100 μmol/L Cd2+separately,the concentration of copper and cadmium,malonaldehyde,phytochelatin and glutathione in roots and leaf were investigated.The results revealed that under stress the concentration of copper and cadmium increased gradually,especially in roots the concentration increased remarkably,75 fold growth approximately,but in leaf the increase was slowly,2-5 fold approximately.The content of cadmium is higher than copper in leaf and roots.Lipid peroxidation in leaf was stronger than that in roots.Under heavy metal stress the concentration of glutathione in leaf was higher than that in roots,while phytochelatins in leaf was lower than that in roots.


Abstract : The air campaign against the Iraqi army in the Kuwait Theater of Operations (KTO) began on the opening day of the war. Eighty B-52s bombed Republican Guard positions, almost 300 A-10 sorties were flown against troop positions along the border, and F-16s attacked ground force command and control positions. Additionally, over 250 other sorties were flown in the KTO on the first day of the war against strategic air offensive targets. The number of attack sorties rose to over 1000 a day in the ensuing weeks. The campaign against the Iraqi ground forces comprised several objectives of the larger air campaign. The objectives of the KTO campaign were to: (1) Gain air supremacy in the KTO by suppressing air defenses; (2) Isolate the Iraqi forces in Kuwait; (3) Render the Iraqi army ineffective; and (4) Support coalition ground forces in the execution of the ground campaign


Non-alcoholic fatty liver disease (NAFLD) is a general term encompassing conditions from increased intrahepatic lipid content (IHLC) (steatosis with triglyceride deposition >5% of hepatocytes) to non-alcoholic steatohepatitis (NASH) with inflammation and/or liver fibrosis [1]. This medical condition has very recently acquired special attention, given the following associations of NAFLD with (1) type 2 diabetes mellitus (T2DM); (2) cardiovascular disease (CVD); and (3) hepatocellular carcinoma (HCC) [2,3]. Indeed, it is speculated that the prevalence of NAFLD approaches 70% in T2DM patients over 50 years old [3]. T2DM patients carry an even higher risk of NASH, malignancy, and CVD, whereas the allegedly benign isolated steatosis is nowadays considered to predict disease progression [1]. In the light of these observations, implementation of specific screening and treatment algorithms for T2DM patients with NAFLD seems imperative [1]. Deplorably, we still lack licensed pharmacological agents for NAFLD treatment [4]. Therefore, drugs available for T2DM therapy have been tested in NAFLD. Among them, recent randomized controlled trials with metformin have yielded negative results [1]. Conversely, 51% of prediabetes (n = 49) or T2DM patients (n = 52) with biopsy-proven NASH who were administered pioglitazone (45 mg/day) additionally to hypocaloric diet for 36 months achieved NASH resolution with two-thirds of them accomplishing reduction in the NAFLD activity score (both p < 0.001) [5], whereas, in a very recent meta-analysis, pioglitazone was associated with improved advanced fibrosis, fibrosis of any stage, and NASH resolution among patients with NASH, with or without diabetes [6]. Although we currently cannot be sure whether the aforementioned effects change the natural history, experts now suggest that pioglitazone alone or in combination with statins or ezetimibe merits special consideration in NAFLD/NASH patients at high CVD or HCC risk [4]. Additional agents have also been tested in NAFLD [7–18]. In a double-blinded, randomized, phase 2 trial [7], liraglutide (1.8 mg/day) or placebo was administered for 48 weeks to 52 obese insulin-resistant NASH patients (1/3 had T2DM). Definite NASH histological resolution was observed in 39% of liraglutide-treated patients versus 9% with placebo. Liraglutide achieved significant body weight reduction but failed to improve fibrosis [7]. Finally, a number of other therapies have biopsy-proven effects on NASH [1,8,9]. Among them, vitamin E (in a daily dose of 800 IU) has been associated among non-diabetic adults with amelioration of hepatic cell injury (NASH improvement vs. placebo was: 43% vs. 19%, p = 0.001; number needed to treat: 4.2) but only borderline significance was attained in NASH resolution (36% vs. 21%, p = 0.05 vs. placebo) [1,9]. Moreover, a number of studies have suggested increased risk of prostate cancer with long-term exposure [1]. Likewise, bariatric surgery seems promising in the improvement of biochemical and histological features of NAFLD [8], but longterm trials are needed to clarify its role [1]. Of note, exogenous administration of ursodeoxycholic acid, a non-toxic bile acid led to significant reduction of aminotransferases, but this did not always correlate with histological improvement [9].


Critics often assume Edgar Lee Masters's best-selling 1915 collection of poems, Spoon River Anthology, to be a damning account of small-town corruption and sexual degeneration. This essay argues the counter-intuitive claim that the anthology instead confirms a pastoral image of small town life even as it appears to negate this ideal. I suggest that Spoon River Anthology paradoxically confirms the idyllic image of the small Midwestern town through the collection's representations of adultery, unrestrained lust, and promiscuity – activities that were often associated with an "unnatural" version of heterosexuality in the early twentieth-century United States. To show that Masters's critical account of Spoon River's citizenry serves to substantiate representations of the heartland as an idyllic space for opposite-sex couplings, I offer close readings of two poems –"Lucinda Matlock" and "Washington McNeely"– and illustrate how they each present readers with compulsory versions of heterosexual couplings that contrast to the "deviant" opposite-sex activities that saturate the remainder of the text.

To meet the rapid growth of massive user access requirement and service experience rate, user-centric ultra-dense networks are proposed to serve each user seamlessly based on dynamic access point groups, which breaks through the traditional network-centric cellular architecture. However, a large number of access points deployment and the long transmission distance between users and access points make the network cost and delay increase. Therefore, in this paper, a user-centric content sharing mechanism for device-to-device (D2D) cellular networks is proposed by multi-device-to-device (MD2D) user cooperation, which can not only shorten the content transmission distance, but also guarantee the quality of service at the lowest cost. In particular, in order to ensure quality of service at the lowest cost, a noncooperative game-based D2D cooperative user allocation scheme is proposed. However, the allocation scheme does not take into account the conflicts of interest between users because the allocated D2D cooperative users may meet the service requirement of multiple users at the same time. Accordingly, a Vickrey–Clarke–Groves based user trustworthy auction mechanism is proposed to avoid interest conflicts caused by the above-mentioned reasons. The results show that the proposed mechanism not only reduces the consumption and delay of content transmission, but also greatly help the base stations reduce base station load.


This study explored how global citizenship as an overarching aim of social
studies can be realized and meaningfully delivered to students in a high school
social studies classroom. Using a case study of an exemplary social studies
teacher, Julia, this study focused on her curricular meaning making and
pedagogical decision making as ways to promote global citizenship in a 9th grade
social studies classroom in the United States. The findings of this study
demonstrate that Julia's curricular decisions and pedagogical practices largely
advocated world justice and governance and cosmopolitan notions of global
citizenship, and emphasized a cooperative nature and dialogic understanding of
the world. Specific pedagogical approaches Julia used are as follows: (1) global
history and culture as interpretation and analysis, (2) from local to global,
(3) cultural diversity, tolerance, and respect, (4) stay tuned for current events,
and (5) visual texts. in-class activity, primary sources, student work sample, and
homework/assignment guidelines are presented as examples of her actual
teaching practices. This study, based upon a real-world classroom observation and
interview data, seeks to provide implications for global citizenship education in

The paper is aimed at regulated medieval settlements in Scandinavia (named mostly, although not always correctly solskifte). These systems comprehend green villages and row villages as well as regular chessboard-like field arrangements. In these systems each farmer had strips in each furlong. The location of his strip within the furlong was constant in relation to that of other farmers and was determined according to the sequence of houses in the village, counting with reference to the apparent course of the sun across the sky and beginning mostly in the south and east. Widths of the house plots were proportional to fiscal assessment of their farmsteads. For further description of those concepts see English references. Recent research in the Czech Republic revealed signs of applying similar planning principles. This is especially the case of the village of Nova Lhota, founded probably in the first half of the 16th century. Ordering of field strips mirror here the sequence of house plots in the village. Better understanding of genetic links between Scandinavian concepts of medieval landscape planning concepts and similar principles found in central Europe is thus the major task of future research.


The aim of this study was to investigate the effect of post-activation potentiation (PAP), carbohydrate (CHO) mouth rinse, and the combination of both strategies on repeated sprint ability (RSA). Twenty male soccer players (age = 18.9 ± 0.9 years, body mass = 71.8 ± 5.2 kg, height = 178.2 ± 6.3 cm) randomly performed four experimental conditions before RSA test (six sets of 40 m): (I) placebo (PLA) control, (II) CHO mouth rinse (6% maltodextrin), (III) PAP + PLA, and (IV) PAP + CHO. The PAP protocol involved two sets of five repetitions (80% 1RM) of the back squat exercise. A one-way repeated measures analysis of variance followed by Bonferroni post hoc test was used to compare the experimental conditions. Results indicated that PAP + CHO and PAP + PLA had better results for the variables best sprint time, mean sprint time, and total sprint time compared with CHO and PLA ( p < 0.001; small effect size). No significant interaction between the experimental conditions was observed for the variable RSA performance decrement, and no significant difference between conditions, i.e., PAP + CHO vs. PAP + PLA and CHO vs. PLA control was found. In conclusion, PAP positively affects RSA performance in soccer players; however, the combination of PAP and CHO mouth rinse showed no additional effect.


A shell theory is developed in terms of electron creation and annihilation operators. Seniority scheme is defined through pair creation and pair annihilation operators, which are defined on the concept of Kramers's ]::air states. Matrix relations for single-electron tensor operators are derived through commutation relations between the operator and the pair operators. Matrix relations are also found of a two-electron scalar operator. A definition is given of complementary transformation, which relates matrix elements of the electron operators mentioned above between complementary states. The complementary transformation leads to theorems for half-filled shells.


This paper presents the content of an address given at the IUTAM symposium on the optimal control of mechanical systems (Moscow, April 1992). The problem of the optimal control of the motion about the center of mass of large space objects is examined. The considerable increase in the size and inertial characteristics of present and projected planned space apparatus (space ships, orbital and interplanetary stations, space platforms, solar orbital power plants, etc.), the wide spectrum of problems confronting them, the long periods of use, and the limitations on the power possibilities of control systems render this problem quite pressing. The solutions of a number of problems of optimal program control of the spatial orientation of spacecraft [1-4] were included in the address. Various control principles were examined : using retrorockets, by an active change in the moments of inertia of the system, and by the use of force gyroscopes.


A 67-year-old man with history of tobacco smoking presents to the emergency department with sudden onset, retrosternal chest pain radiating to the neck and associated with diaphoresis and nausea. On examination, his blood pressure was 106/42 mm Hg, pulse of 73 beat/min. He was pale, diaphoretic with IV/VI diastolic blowing murmur of unknown chronicity heard at the left sternal border. His distal pulses were faint but symmetric in all extremities. No marfanoid features. ECG showed sinus rhythm with ST segment elevation in leads aVR and V1, with widespread ST segment depression (figure 1). He underwent emergent coronary angiogram with initial diagnosis of acute coronary syndrome and impending cardiogenic shock. Angiogram revealed type-A aortic dissection extending to the aortic arch with concomitant aortic regurgitation (AR) (videos 1 and 2). On prompt recognition of aortic dissection, he was transferred to the operating room for emergent surgical repair. Intraoperative transoesophageal echocardiography (TEE) showed circumferential dissection of the proximal aorta with diastolic prolapse of a cylinder-shaped intimal flap into the left ventricle causing severe AR (videos 3–5). The dissection was successfully repaired using 30 mm Hemashield Platinum …

Observations of circumstellar disks provide a powerful tool for our understanding of planetary system dynamics. Analogs to the solar system asteroid belts, debris disks result from the collision of the remaining solid material of the planet formation process. Even if the presence of disks is now reported for hundreds of stars, its detection around stars similar to the Sun is still very sparse. We report the results of a search for debris disks around Kepler stars with surface physical parameters close to solar values, including rotation period, using observations by the Wide-field infrared Survey Explorer. From the entire sample of Kepler stars, 881 targets were identified with these parameters and only six of them (KIC 1868785, 7267949, 7435796, 10533222, 11352643, and KIC 11666436) show unambiguous infrared excess, for which we determined as debris disk physical parameters. Interestingly, the present study reveals traces of debris disks much more massive and brighter than the solar system zodiacal dust, probably resulting from recent violent collisional events, orbiting stars with ages around the solar values.


Abstract Pigeon Guillemots (Cepphus columba) are diving seabirds that forage near shore and feed their chicks demersal and schooling fishes. During nine years between 1979 and 1997, we studied chick diet, chick growth rate, and reproductive success of Pigeon Guillemots at Prince William Sound, Alaska, to determine factors limiting breeding populations. We found evidence for prey specialization among breeding pairs and detected differences in reproductive success between specialists and generalists. Pairs that specialized on particular prey types when foraging for their chicks fledged more chicks than those that generalized, apparently because they delivered larger individual prey items. Reproductive performance also varied among guillemot pairs as a function of the proportion of high-lipid schooling fishes fed to the chicks. Pairs that delivered primarily high-lipid fishes (Pacific sand lance [Ammodytes hexapterus] and Pacific herring [Clupea pallasii]) had higher overall reproductive success than pairs that delivered primarily low-lipid demersal fishes (e.g. sculpins, blennies, stichaeids, and pholidids) and gadids. The proportion of high-lipid fishes in the diet was positively related to chick growth, suggesting that piscivorous seabird chicks benefit from eating species with high-energy densities during development. The diet of Pigeon Guillemot chicks showed high annual variation from 1979 to 1997, presumably because of fluctuations in abundance of Pacific sand lance, a high-lipid schooling fish. Regression analyses suggest that the percent occurrence of high-lipid fishes in the diet affected chick growth rate at the population level. We conclude that Pigeon Guillemots benefit by specializing when selecting prey for their chicks, and that high-lipid schooling fishes enhance chick growth and reproductive success.

Growth and development of selected dinitroaniline-resistant (DR) and -susceptible (DS) goosegrass populations were compared in field studies in replacement series, in association with cotton, and under noncompetitive conditions. The DR 'Florence' (FR) and DS 'Orangeburg' (OS) populations were similar in competitiveness as indicated by relative yields (RY) and relative crowding coefficients (RCC) for vegetative and reproductive biomass production in a replacement series. Relative growth of the FR and DS 'Anderson' (AS) populations in replacement series was similar when vegetative biomass was considered, but reproductive biomass of the AS population declined as proportion of FR population increased. RCC values also indicated that the FR population interfered with reproductive development of the AS population. In field studies, the FR population produced greater vegetative biomass than either DS population, while similar reproductive biomass occurred for the FR and OS populations. Inflorescence dry weights were greater for the FR than the AS population under noncompetitive conditions and in cotton, but were greater for the AS population in replacement series studies. The competitiveness of DR and DS goosegrass biotypes appears to be more related to growth characteristics of individual populations than to response to dinitroaniline herbicides.


To research the seismic behaviors of a new kind of steel column based with wedge devices,the finite element software ANSYS is used to build three dimensional models for two commonly used types of the column bases and the analysis of seismic behavior of the column base under the low cyclic loading is conducted.The M-θ hysteretic curves and M-θ skeleton curves of the column base are obtained from the finite element analysis.The energy dissipation capacity and ductility are also researched from the curves.Comparisons between different types of the column base and different axial compressions are conducted.The results show that the restoring characteristics of the new kind columns are non-slip-type.The M-θ hysteretic curves of bases are plumpy and have good energy dissipation capacity and ductility.These indicate good seismic abilities of the column base.The results provide references for the design and application of the new kind column base.

ABSTRACT Background: Eating frequency (EF) may influence obesity-related disease risk by attenuating postprandial fluctuations in hormones involved in metabolism, appetite regulation, and inflammation. Materials/methods: This randomized crossover intervention trial tested the effects of EF on fasting plasma insulin-like growth factor-I (IGF-1) and leptin. Fifteen subjects (4 males, 11 females) completed two eucaloric intervention phases lasting 21 days each: low EF ("low-EF"; 3 eating occasions/day) and high EF ("high-EF"; 8 eating occasions/day). Subjects were free-living and consumed their own meals using individualized structured meal plans with instruction from study staff. Subjects completed fasting blood draws and anthropometry on the first and last day of each study phase. The generalized estimated equations modification of linear regression tested the intervention effect on fasting serum IGF-1 and leptin. Results: Mean (± SD) age was 28.5 ± 8.70 years, and mean (± SD) Body Mass Index was 23.3 (3.4) kg/m2. We found lower mean serum IGF-1 following the high-EF condition compared to the low-EF condition (P < 0.001). There was no association between EF and plasma leptin (P = 0.83). Conclusion: These results suggest that increased EF may lower serum IGF-1, which is a hormonal biomarker linked to increased risk of breast, prostate, and colorectal cancer.


This paper is about the genre of tragedy and how Henry James' book, The Portrait of a Lady, is a representation of tragedy. Many critics view his main character, Isabel, as a tragic figure. This is, however, not true. I prove this by first searching for the meaning of tragedy, and second, analyzing Isabel's character and studying theoretical pieces on the topic. In order to be a tragic character, life, in a sense, has to be over with - completed. Isabel's is not. It is for this reason that she is the nontragic in a tragedy. Based on this information, I found that although Isabel's marriage and situation in life are tragic, they have not consumed her person; therefore, she is the non-tragic in a tragedy.

While studying the results of each experiment, it was concluded that Oroxylum indicum, the unexplored medicinal plant was promisable in cancer treatment with high mode of activity and low cost in the contest of sky rocketting prices of drugs.


A computation programme for the sound absorption of microperforated absoberes is based on Maa's theory. Comparison between the theoretical and experimental results shows good agreement for normally incident sound waves. The programme enables accurate definition of the geometrical parameters of a microperforated panel construction according to the respective practical requirements. Estimates are also given for impinging diffuse sound fields. As a successful example, a fully transparant microperforated absorber made of plexiglass was installed in order to eliminate the acoustic and electroacoustic disturbances caused by the large cylindrical glass partition walls between the central plenum and surrounding lobby.


Data on 709 patients who had a resection for colorectal carcinoma at Concord Hospital between 1971 and 1980 were studied to determine the independent effects on survival of several patient characteristics and pathological variables using the Cox regression model. Clinicopathological stage had the strongest association. Other variables ranked according to their relative importance independent of stage were: histological grade, level of direct spread, the presence of venous invasion, age and sex of the patient and the presence of obstruction.

This study aims to delineate and evaluate the reservoir characteristics and stratigraphic patterns of Miocene and Pliocene sediments in shallow and deep Mediterranean offshore Nile Delta. Pliocene & Miocene reservoirs are ideal cases for shelf slope and sub-sea depositional environment, which deposited as channel fan complex and deep seated sub sea channels. Pliocene reservoirs are represented by Kafr El Sheikh and El Wastani Formations. Kafr El Sheikh sands are good examples for fining upward turbidities sequence in the down thrown side of east-west growth faults (e.g.. Seth, Ha"py, King & Max gas discoveries). Kafr El Sheikh formation is considered the primary reservoir for many recent gas discoveries with very thick net pay.


Phenylpropionic acids are commonly used in the synthesis of pharmaceuticals, cosmetics, and fine chemicals. However, the synthesis of phenylpropionic acids faces the challenges of high cost of substrates and a limited range of products. Here, we present an artificially designed amino‐group‐transformation biocatalytic process, which uses simple phenols, pyruvate, and ammonia to synthesize diverse phenylpropionic acids. This biocatalytic cascade comprises an amino‐group‐introduction module and three amino‐group‐transformation modules, and operates in a modular assembly manner. Escherichia coli catalysts coexpressing enzymes from different modules achieve whole‐cell simultaneous one‐pot transformations of phenols into the corresponding phenylpropionic acids including (S)‐α‐amino acids, α‐keto acids, (R)‐α‐amino acids, and (R)‐β‐amino acids. With cofactor recycling, protein engineering, and transformation optimization, four (S)‐α‐amino acids, four α‐keto acids, four (R)‐α‐amino acids, and four (R)‐β‐amino acids are synthesized with good conversion (68–99%) and high enantioselectivities (>98%). Therefore, the amino‐group‐transformation concept provides a universal and efficient tool for synthesizing diverse products.
