    Photo of Susan L Greenblatt Figure 1. Susan in May, 1994 This volume is dedicated to the memory of Susan L Greenblatt, the wife of Steven L Guberman. Susan attended 6 of the 8 dissociative recombination (DR) meetings. Her advice and wise counsel played a vital role in the organization of several of these meetings. The fifth meeting in Chicago in 2001 was her idea and it would not have occurred without her encouragement. Susan was always amused by the memory of the first group dinner at the second DR meeting at St Jacut in 1992. As we went around the dinner table identifying ourselves, it soon became her turn. Susan was a sociologist and after introducing herself she said: "I am not a chemist". A spontaneous chorus of attendees proclaimed "Neither are we!". Her husband and a few other chemists abstained. In 1983, Susan and I established the Institute for Scientific Research (ISR). The name was chosen so as to span sociology and chemical physics. Four years prior, an ophthalmologist had diagnosed a rare retinal condition of unknown origin and advised her to change her profession to one that did not involve reading. (She was able to read for the rest of her life.) Twenty years later we learned that the cause of the retinal and all her other health problems was a recently discovered rare mitochondrial mutation. Her experience with ophthalmologists and her life-long keen sense of injustice, led her to write a grant proposal to the US Department of Education to survey all ophthalmologists in the US to determine whether they were aware of and whether they told their patients about resources and aids that could help them to continue reading and participating in everyday activities. As part of the grant and based upon the survey results, she proposed to set up low-vision training programs for ophthalmology residents. We knew that the competition for funding was intense and included several well-known and more established organizations. Nevertheless, the proposal was funded

    Full Text Available A questão central discutida neste artigo é a existência ou não de um dever legal do juiz de decidir de uma determinada forma em caso de 'lacuna da lei', termo empregado por H. L. A. Hart, ou em 'casos difíceis', termo adotado por Ronald Dworkin. Este artigo conclui que embora Hart e Dworkin admitam uma forma fraca de discricionariedade judicial, eles adotam visões opostas quanto à existência daquele dever. Ao defender uma noção de completude legal, ao discordar da regra social de reconhecimento e ao incluir princípios não convencionais no conceito de direito, Dworkin fundamenta a existência daquele dever judicial, oferecendo critérios objetivos de decisão mesmo para casos difíceis.The central issue discussed in this article is whether a judge has a legal duty to decide in an specific manner in cases of legal lacunae, to use H. L. A. Hart's expression, or in hard cases, to use Ronald Dworkin's expression. It argues that, though both Hart and Dworkin admit a weak form of judicial discretion, they hold opposite views on the existence of that duty. By adopting a notion of legal completeness, which may disagree with a social rule of recognition, and by including non-conventional principles in the concept of Law, Dworkin offers the justification for that judicial duty. He also offers objective criteria of judicial decision even in hard cases.

  7. Bell's Palsy.

    Science.gov (United States)

    Reich, Stephen G

    2017-04-01

    Bell's palsy is a common outpatient problem, and while the diagnosis is usually straightforward, a number of diagnostic pitfalls can occur, and a lengthy differential diagnosis exists. Recognition and management of Bell's palsy relies on knowledge of the anatomy and function of the various motor and nonmotor components of the facial nerve. Avoiding diagnostic pitfalls relies on recognizing red flags or features atypical for Bell's palsy, suggesting an alternative cause of peripheral facial palsy. The first American Academy of Neurology (AAN) evidence-based review on the treatment of Bell's palsy in 2001 concluded that corticosteroids were probably effective and that the antiviral acyclovir was possibly effective in increasing the likelihood of a complete recovery from Bell's palsy. Subsequent studies led to a revision of these recommendations in the 2012 evidence-based review, concluding that corticosteroids, when used shortly after the onset of Bell's palsy, were "highly likely" to increase the probability of recovery of facial weakness and should be offered; the addition of an antiviral to steroids may increase the likelihood of recovery but, if so, only by a very modest effect. Bell's palsy is characterized by the spontaneous acute onset of unilateral peripheral facial paresis or palsy in isolation, meaning that no features from the history, neurologic examination, or head and neck examination suggest a specific or alternative cause. In this setting, no further testing is necessary. Even without treatment, the outcome of Bell's palsy is favorable, but treatment with corticosteroids significantly increases the likelihood of improvement.

    We analyze foundational consequences of recently reported loophole free tests of violation of Bell's inequality. We consider two interpretations of these remarkable experiments. The conventional one is ''Einstein was wrong and Bohr was right, there is spooky action at a distance, quantum realism is incompatible with locality.'' However, in line with discussions in literature during last decade, we show that it is still possible to treat quantum mechanics without appealing to nonlocality or denying realism. We hope that this note will call the attention of experts in quantum foundations and convince them that the case is not closed, so that they should come with their own comments on the status of the final Bell test.

    Bell's palsy is an idiopathic, unilateral, acute paresis or paralysis of facial movement caused by dysfunction of the lower motor neurone. Up to 30% of people with acute peripheral facial palsy have an alternative cause diagnosed at presentation or during the course of their facial palsy. Alternative causes are higher in children (>50%), warranting specialist evaluation at presentation. Severe pain, vesicles (ear or oral), and hearing loss or imbalance, suggest Ramsay Hunt syndrome caused by ...

    Richman, Barbara T.

    ‘I was five years old when I first asked my mother about the lights in the night sky, and I haven't run out of questions yet.’ So says Helen Hart, the 1982 recipient of the June Bacon-Bercy Scholarship for Women in Atmospheric Sciences.A graduate student in the astrophysics department at the University of Colorado in Boulder, Hart earned her B.A. degree in 1981 with high honors in physics at the University of Montana in Missoula. Her research interests center on atmospheric structures and motions and on the developmental history o f the solar system. ‘I would like to study the effects of albedo changes over varying scale lengths on energy distribution and atmospheric dynamics,’ Hart said. Currently, she is a research assistant for the Voyager 2 photopolarimeter team at the Laboratory for Atmospheric and Space Physics at the university. She is working on using data on the polarization of scattered light to model the atmospheres of Saturn and its satellite, Titan.

  17. Maarten’t Hart bestaat niet

    Full Text Available Maarten 't Hart werd in 1944 geboren in het Nederlandse stadje Maasshuis. Daar spelen verscheidene van zijn autobiografische romans, een teken dat hij verknocht is aan zijn geboortegrond. In zijn eerste romans Stenen voor een ransuil (1971 en Ik had een wapenbroeder (1973 staat het thema van de homoseksualiteit centraal. In zijn latere werk spelen de liefde tussen man en vrouw en de liefde voor de natuur en de muziek een grote rol. Veel van zijn werk, vooral zijn beroemdste roman Een vlucht regenwulpen, staat in het teken van de gewenste eenzaamheid. Behalve zeventien romans en verhalenbundels (de meest recente roman Onder de korenmaat verscheen in 1991 publiceerde Maarten 't Hart een tienlal boeken met populair-welenschappelijke studies en essays. In Ratten (1973 gaat het over zijn voorliefde voor een gediscrimineerd dier, in De som van misverstanden (1978 beschrijfl hij zijn liefde voor de literatuur, in De vrouw bestaat niel trekt hij len strijde tegen het feminisme en in Een dasspeld uit Toela (1990 rekent hij af met de literatuurcritici. Maarten't Hart is een uitnemend en gevoelig verteller Waarschijnlijk is het aan zijn nogal slordige stijl en zijn afkeer van het experiment in de romankunst te wijten dal hij na de Multatuliprijs-1975 voor zijn verhalenbundel Het vrome volk (1974 geen enkele lileraire prijs meer heeft gekregen. Wei halen zijn boeken hoge oplagen en is hij ereburger van Maasshuis.

    The science universe is dimmer after one of our brightest stars, Susan Lee Lindquist, was taken by cancer on October 27, 2016. Sue was an innovative, creative, out-of-the-box scientific thinker. She had unique biological intuition-an instinct for both the way things worked and the right questions to ask to uncover new research insights. Her wide-ranging career began with the study of protein folding and molecular chaperones, and she went on to show that protein folding can have profound and unexpected biological effects on such diverse processes as cancer, evolution, and neurodegenerative disease. As Sue's laboratory manager, I would like to offer a ground-floor perspective on what made her an exceptional scientist, mentor, and leader. She created a harmonious, collegial environment where collaborative synergy fueled meaningful progress that will impact science for decades to come. © 2017 Bevis.

    Full Text Available Blueberries (2009 by Susan Gibb, published in the ELO (Electronic Literature Organization, invites the reader to travel inside the protagonist’s mind to discover real and imaginary experiences examining notions of gender, sex, body and identity of a traumatised woman. This article explores the verbal and visual modes in this digital short fiction following semiotic patterns as well as interpreting the psychological states that are expressed through poetical and technological components. A comparative study of the consequences of trauma in the protagonist will be developed including psychoanalytic theories by Sigmund Freud, Jacques Lacan and the feminist psychoanalysts: Melanie Klein and Bracha Ettinger. The reactions of the protagonist will be studied: loss of reality, hallucinations and Electra Complex, as well as the rise of defence mechanisms and her use of the artistic creativity as a healing therapy. The interactivity of the hypermedia, multiple paths and endings will be analyzed as a literary strategy that increases the reader’s capacity of empathizing with the speaker.

  4. Susan Sontag — A Forgotten Mother?

    2013-01-01

    Full Text Available The article discusses new and republished translations of Susan Sontag’s work, recently launched by the Karakter publishing house: Regarding the Pan of Others, On Photography, and Against Interpretation and Other Essays. The article focuses on the elements of Sontag’s thought that make her a forgotten mother of feminist and gender theoreticians, as well as such influential critics as Michel Foucault and Roland Barthes. The article points out to continuations of Sontag’s thought in contemporary theoretical and social projects, and to the pertinence of her critical observations on theories based on metaphysics of presence: psychoanalysis, Marxism, or hermeneutics. The article also touches upon history of war photography and related war journalism, and upon the ambivalent quality of imaging of the misery of war. It also present historical and cultural circumstances of the development of Sontag’s thought in the intellectual milieu of New York in the 1960s. The discussion recapitulates the main statements of Sontag’s essays, relating them to a wider theoretical context, which is aimed at a reappraisal of the forgotten intelectual in the history of literature.

  6. Anti-Bell - Refutation of Bell's theorem

    Science.gov (United States)

    Barukčić, Ilija

    2012-12-01

    In general, Albert Einstein as one of "the founding fathers of quantum mechanics" had some problems to accept especially the Copenhagen dominated interpretation of quantum mechanics. Einstein's dissatisfaction with Copenhagen's interpretation of quantum mechanics, the absence of locality and causality within the Copenhagen dominated quantum mechanics lead to the well known Einstein, Podolsky and Rosen thought experiment. According to Einstein et al., the Copenhagen dominated quantum mechanics cannot be regarded as a complete physical theory. The Einstein, Podolsky and Rosen thought experiment was the origin of J. S. Bell's publication in 1964; known as Bell's theorem. Meanwhile, some dramatic violations of Bell's inequality (by so called Bell test experiments) have been reported which is taken as an empirical evidence against local realism and causality at quantum level and as positive evidence in favor of the Copenhagen dominated quantum mechanics. Thus far, Quantum mechanics is still regarded as a "strictly" non-local theory. The purpose of this publication is to refute Bell's original theorem. Thus far, if we accept Bell's theorem as correct, we must accept that +0> = +1. We can derive a logical contradiction out of Bell's theorem, Bell's theorem is refuted.

    2017-01-01

    Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

  1. The Healer's Art (HART): Veterinary Students Connecting with Self, Peers, and the Profession.

    Science.gov (United States)

    Meyer-Parsons, Beatrice; Van Etten, Sarah; Shaw, Jane R

    This case study sought to understand veterinary students' perceptions and experiences of the Healer's Art (HART) elective to support well-being and resilience. Students' "mindful attention" was assessed using the MAAS-State scale. Course evaluations and written materials for course exercises (artifacts) across the 2012-2015 cohorts of Colorado State University's HART veterinary students (n=99) were analyzed for themes using a grounded theory approach, followed by thematic comparison with analyses of HART medical student participants. HART veterinary students described identity/self-expression and spontaneity/freedom as being unwelcome in the veterinary curriculum, whereas HART medical students described spirituality as unwelcome. HART veterinary students identified issues of "competition" and "having no time," which were at odds with their descriptions of not competing and having the time to connect with self and peers within their HART small groups. HART veterinary students shared that the course practices of nonjudgment, generous listening, and presence (i.e., mindfulness practices) helped them build relationships with peers. Although not statistically significant, MAAS pre-/post-scores trended in the positive direction. HART provides opportunities for students to connect with self and foster bonds with peers and the profession, factors that are positively associated with resilience and wellness.

    2017-01-01

    The Belle II detector is now under construction at the KEK laboratory in Japan. This project represents a substantial upgrade of the Belle detector (and the KEKB accelerator). The Belle II experiment will record 50 ab-1 of data, a factor of 50 more than that recorded by Belle. This large data set, combined with the low backgrounds and high trigger efficiencies characteristic of an e+e- experiment, should provide unprecedented sensitivity to new physics signatures in B and D meson decays, and in τ lepton decays. The detector comprises many forefront subsystems. The vertex detector consists of two inner layers of silicon DEPFET pixels and four outer layers of double-sided silicon strips. These layers surround a beryllium beam pipe having a radius of only 10 mm. Outside of the vertex detector is a large-radius, small-cell drift chamber, an ``imaging time-of-propagation'' detector based on Cerenkov radiation for particle identification, and scintillating fibers and resistive plate chambers used to identify muons. The detector will begin commissioning in 2017.

  10. [The Durkheim Test. Remarks on Susan Leigh Star's Boundary Objects].

    Science.gov (United States)

    Gießmann, Sebastian

    2015-09-01

    The article reconstructs Susan Leigh Star's conceptual work on the notion of 'boundary objects'. It traces the emergence of the concept, beginning with her PhD thesis and its publication as Regions of the Mind in 1989. 'Boundary objects' attempt to represent the distributed, multifold nature of scientific work and its mediations between different 'social worlds'. Being addressed to several 'communities of practice', the term responded to questions from Distributed Artificial Intelligence in Computer Science, Workplace Studies and Computer Supported Cooperative Work (CSCW), and microhistorical approaches inside the growing Science and Technology Studies. Yet the interdisciplinary character and interpretive flexibility of Star’s invention has rarely been noticed as a conceptual tool for media theory. I therefore propose to reconsider Star's 'Durkheim test' for sociotechnical media practices.

    Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mono-neuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. Bell's palsy is a rapid unilateral facial nerve paresis (weakness) or paralysis (complete loss of movement) of unknown cause. The condition leads to the partial or complete inability to voluntarily move facial muscles on the affected side of the face. Although typically self-limited, the facial paresis/paralysis that occurs in Bell's palsy may cause significant temporary oral incompetence and an inability to close the eyelid, leading to potential eye injury. Additional long-term poor outcomes do occur and can be devastating to the patient. Treatments are generally designed to improve facial function and facilitate recovery. There are myriad treatment options for Bell's palsy, and some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, numerous diagnostic tests available are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. The primary purpose of this guideline is to improve the accuracy of diagnosis for Bell's palsy, to improve the quality of care and outcomes for patients with Bell's palsy, and to decrease harmful variations in the evaluation and management of Bell's palsy. This guideline addresses these needs by encouraging

  14. HLA Hart, Lon Fuller and the Ghosts of Legal Interpretation

    Directory of Open Access Journals (Sweden)

    Desmond Manderson

    2010-02-01

    Full Text Available Henry James’ short novel The Turn of the Screw appeared in 1898. It is a ghost story, uncanny both in content and in form. It relates such uneventful events that the reader is left turning from interpretation to interpretation, trying to determine just what is going on. Yet like the ghosts themselves, wherever we look, there is nothing to see. Until the very last sentence of the book, which hits one like a fist, nothing happens, nothing is proved, and yet a palpable feeling of tension and anxiety builds. It is therefore not fanciful to suggest that the real power of the story lies not in its narrative but in its rhetoric. The book creates a mood of anxiety that infects the reader’s reading. This is what one might call the ‘performative’ dimension of the story. James’ tale constitutes a reader, alert but confused, who thereby experiences the feeling of being part of a ghost story rather than merely reading about one. Sixty years later, HLA Hart and Lon Fuller likewise do not merely describe two different approaches to legal interpretation: in their style, rhetoric and structure they perform these approaches. This essay similarly wishes to connect its argument with its form and for this reason I have chosen to devote considerable space to discussing a work of literature. The Turn of the Screw illuminates certain essential features of the Hart/Fuller debate. Both are tales about law, interpretation, and ghosts. Through James, this essay argues that the debate between Hart and Fuller epitomizes legal interpretation as haunted. Rhetorically, they present two largely incommensurable visions of law. Yet their efforts to exclude the other’s approach fails. But instead of choosing between Hart and Fuller we can gain a richer understanding of legal interpretation if we treat their performance as mutual and interactive. I do not mean that Hart and Fuller can in any way be reconciled through compromise or synthesis. I mean rather that each

  15. Implementation of WirelessHART in the NS-2 Simulator and Validation of Its Correctness

    Full Text Available One of the first standards in the wireless sensor networks domain,WirelessHART (HART (Highway Addressable Remote Transducer, was introduced to address industrial process automation and control requirements. This standard can be used as a reference point to evaluate other wireless protocols in the domain of industrial monitoring and control. This makes it worthwhile to set up a reliable WirelessHART simulator in order to achieve that reference point in a relatively easy manner. Moreover, it offers an alternative to expensive testbeds for testing and evaluating the performance of WirelessHART. This paper explains our implementation of WirelessHART in the NS-2 network simulator. According to our knowledge, this is the first implementation that supports the WirelessHART network manager, as well as the whole stack (all OSI (Open Systems Interconnection model layers of the WirelessHART standard. It also explains our effort to validate the correctness of our implementation, namely through the validation of the implementation of the WirelessHART stack protocol and of the network manager. We use sniffed traffic from a realWirelessHART testbed installed in the Idrolab plant for these validations. This confirms the validity of our simulator. Empirical analysis shows that the simulated results are nearly comparable to the results obtained from real networks. We also demonstrate the versatility and usability of our implementation by providing some further evaluation results in diverse scenarios. For example, we evaluate the performance of the WirelessHART network by applying incremental interference in a multi-hop network.

    2014-12-01

    Full Text Available The article focuses on the symbolic meaning of Russian ringing of bell in the Russian discourse. According to Lotman’s definition of symbol, it has dual nature: an invariant essence and its modification in relation to the cultural context. The article introduces informative and linguistic modifications of the bell topic in the Russian poetic discourse of the 19th, the 20th and the beginning of the 21st century. The author of the article provides the detailed analysis of such discursive descriptions of bell ringing as the ringing of church bells and alarm . The author arrives at the conlusion that the alarm topic prevails in contemporary poetry and this indicates the state of public dissatisfaction. In the 19th and the 20th centuries lexemes the ringing of church bells and alarm were used literally, but in the 21st century lexeme alarm acquires metaphorical meaning of call for blood.

    Full Text Available El objetivo del artículo es ofrecer una nueva interpretación sobre el papel de la coacción en la teoría de las reglas de H. L. A. Hart. En primer lugar, se explica por qué una inadecuada interpretación de la coerción rinde imposible la distinción entre reglas primarias secundarias y primarias, central en el pensamiento de Hart. En segundo lugar, se distingue entre coerción y reproche social, además se analiza el carácter epistemológico de El Concepto de derecho. Con base en estas dos precisiones, se sugiere que el papel de la coacción en las reglas secundarias es determinar cuándo estamos en presencia de una regla. Finalmente, se proponen posibles líneas de investigación y de solución de controversias en torno a la teoría de Hart, según las tesis defendidas en el artículo.The objective of this article is to offer a new interpretation of the role of coercion in Hart's theory of rules. Firstly, it is discussed why an inaccurate interpretation of coercion makes impossible the important distinction between primary and secondary rules drawn by Hart. Secondly, it is analyzed the epistemological character of Hart's theory and the difference between coercion and social complains. Bases on these two clarifications, it is suggested that the role of coercion in secondary rules is to determine when we are in presence of a rule. Finally, some research lines and the solution to some controversies, following the main theses defended in this article, are suggested.

  7. Routing and Scheduling Algorithms for WirelessHART Networks: A Survey

    Science.gov (United States)

    Nobre, Marcelo; Silva, Ivanovitch; Guedes, Luiz Affonso

    2015-01-01

    Wireless communication is a trend nowadays for the industrial environment. A number of different technologies have emerged as solutions satisfying strict industrial requirements (e.g., WirelessHART, ISA100.11a, WIA-PA). As the industrial environment presents a vast range of applications, adopting an adequate solution for each case is vital to obtain good performance of the system. In this context, the routing and scheduling schemes associated with these technologies have a direct impact on important features, like latency and energy consumption. This situation has led to the development of a vast number of routing and scheduling schemes. In the present paper, we focus on the WirelessHART technology, emphasizing its most important routing and scheduling aspects in order to guide both end users and the developers of new algorithms. Furthermore, we provide a detailed literature review of the newest routing and scheduling techniques for WirelessHART, discussing each of their features. These routing algorithms have been evaluated in terms of their objectives, metrics, the usage of the WirelessHART structures and validation method. In addition, the scheduling algorithms were also evaluated by metrics, validation, objectives and, in addition, by multiple superframe support, as well as by the redundancy method used. Moreover, this paper briefly presents some insights into the main WirelessHART simulation modules available, in order to provide viable test platforms for the routing and scheduling algorithms. Finally, some open issues in WirelessHART routing and scheduling algorithms are discussed. PMID:25919371

    2010-01-01

    During the Nobel prize-winning UA1 experiment, scientists in the control room used to ring a bell if a particularly interesting event had occurred. Today, the “CMS Exotica hotline” routine produces a daily report that lists the exotic events that were recorded the day before.   Display of an event selected by the Exotica routine. Take just a very small fraction of the available data (max. 5%); define the events that you want to keep and set the parameters accordingly; run the Exotica routine and only look at the very few images that the system has selected for you. This is the recipe that a small team of CMS researchers has developed to identify the signals coming from possible new physics processes. “This approach does not replace the accurate data analysis on the whole set of data. However, it is a very fast and effective way to focus on just a few events that are potentially very interesting”, explains Maurizio Pierini (CERN), who developed the...

  10. The Controversy About The Essence Of Law: A Dispute Between Hart And Dworkin

    Directory of Open Access Journals (Sweden)

    Petrus C. K. Bello

    2012-01-01

    Full Text Available Does the law merely contain rules? Or does it also include morality? The debate between H.L.A. Hart and Ronald Dworkin revolved around this very issue. Hart considered the law is nothing more than a set of rules whereas Dworkin believed that the law contains not only the rules but also principles which are morality and justice. This paper is trying to explore the issue of the relationship of law and morality in the context of this debate between Hart and Dworkin. The debate itself is very significant in the study of law. Following their arguments we can learn a lot about how the law should be understood and practiced. By listening to their whole debate we will also know that Hart’s positivistic thought and Dworkin’s tendency towards the natural law are not mutually negating. Hart Positivism is not anti-morality. It is precisely through positivism which he defended Hart aims at safeguarding the law by morality; whereas Dworkin has shown what had previously forgotten by the legal positivistic way of thinking, that is moral principles are integral parts of the law.

    The major goals of our work on Belle II were to complete our contributions, a 64-channel PIN diode-based radiation monitor, to the precursor detector called Beast II and the electronics for the endcap K-Long/Muon (E-KLM) detector. This was done by Professor Cinabro, Technician Gutierrez, and undergraduate labor supported by US-Japan funds. Professor Bonvicini through US-Japan funds led the development and installation of a beamstrahlung monitor system in the Belle II interaction region. Graduate students Farhat and DiCarlo worked on this. We also worked on charm physics analysis.

    Full Text Available The idiopathic facial paralysis or Bell's palsy installs abruptly or within a few hours, without any apparent cause. It corresponds to approximately 75% of all peripheral facial palsies. Three theories try to explain its pathogenecity: vascular-ischemic, viral and auto-immune. We reviewed the records of the EMG Sector, Hospital do Servidor Público Estadual (São Paulo, Brazil, from 1985 to 1995 and found 239 cases of Bell's palsy. Data were analysed according to age, gender, seasonal distribution of cases. There was a predominance of cases in the 31 - 60 age bracket (40.59 %. The female gender was responsible to 70.71 % of cases. There was a predominance of cases in winter (31.38 % and autumn (30.13 %, which was statiscally significant. These findings let us to suppose that Bell's palsy predominates in females, in 41-60 years age bracket, and occurs predominantly in cold months.

  7. Bell inequalities from group theory

    Science.gov (United States)

    Hillery, Mark; Guney, Ugur

    2015-05-01

    Bell inequalities are inequalities containing probabilities of measurement results that are obeyed by probabilities that come from a local, realistic theory but can be violated if the probabilities come from quantum mechanics. They can be also be formulated as nonlocal games in which quantum mechanical resources allow for higher winning probabilities than purely classical resources. Besides their intrinsic interest, these inequalities have proven to be useful in cryptography and entanglement testing. In an earlier study, we showed that it is possible to use group actions for cyclic groups to generate two-party Bell inequalities. This has now been extended to more than two parties and to non-Abelian groups. We will explicitly look at the nonlocal games generated by two groups of 6 elements, one Abelian and one non-Abelian, and compare their structures.

    In this work, we have studied the possibility of setting up Bell's inequality violating experiment in the context of cosmology, based on the basic principles of quantum mechanics. First we start with the physical motivation of implementing the Bell inequality violation in the context of cosmology. Then to set up the cosmological Bell violating test experiment we introduce a model independent theoretical framework using which we have studied the creation of new massive particles by implementing the WKB approximation method for the scalar fluctuations in the presence of additional time-dependent mass contribution in the cosmological perturbation theory. Here for completeness we compute the total number density and the energy density of the newly created particles in terms of the Bogoliubov coefficients using the WKB approximation method. Next using the background scalar fluctuation in the presence of a new time-dependent mass contribution, we explicitly compute the expression for the one point and two point correlation functions. Furthermore, using the results for a one point function we introduce a new theoretical cosmological parameter which can be expressed in terms of the other known inflationary observables and can also be treated as a future theoretical probe to break the degeneracy amongst various models of inflation. Additionally, we also fix the scale of inflation in a model-independent way without any prior knowledge of primordial gravitational waves. Also using the input from a newly introduced cosmological parameter, we finally give a theoretical estimate for the tensor-to-scalar ratio in a model-independent way. Next, we also comment on the technicalities of measurements from isospin breaking interactions and the future prospects of newly introduced massive particles in a cosmological Bell violating test experiment. Further, we cite a precise example of this setup applicable in the context of string theory motivated axion monodromy model. Then we

  9. Do resonating bells increase jellyfish swimming performance?

    Science.gov (United States)

    Hoover, Alexander; Miller, Laura

    2013-11-01

    A current question in swimming and flight is whether or not driving flexible appendages at their resonant frequency results in faster or more efficient locomotion. It has been suggested that jellyfish swim faster and/or more efficiently when the bell is driven at its resonant frequency. Previous work has modeled the jellyfish bell as a damped harmonic oscillator, and this simplified model suggests that work done by the bell is maximized when force is applied at the resonant frequency of the bell. We extend the idea of resonance phenomena of the jellyfish bell to a fluid structure interaction framework using the immersed boundary method. We first examine the effects of the bending stiffness of the bell on its resonant frequency. We then further our model with the inclusion of a ``muscular'' spring that connects the two sides of a 2D bell and drives it near its resonant frequency. We use this muscular spring to force the bell at varying frequencies and examine the work done by these springs and the resulting swimming speed. We finally augment our model with a flexible, passive bell margin to examine its role in propulsive efficiency.

    To determine the feasibility of wind-electric systems, six generation expansion alternatives were examined for Hart, Michigan--a city of 2,500 located near Lake Michigan where the average coastal wind velocities range from 5 to 7 m/s. Five of the alternatives included combinations of 500 and 1500 kW wind turbines (1975 GE parameters) and a 1 MW hydro plant while the last was a 3600 kW diesel generator. Wind velocity was estimated using data from U.S. Coast Guard stations along the shore and verified by a two-year measurement program. The Hart electrical system was represented by an hourly production cost program and the total cost calculations followed the ERDA/EPRI standard for solar energy evaluation.

    Full Text Available Legal positivism positions the law in the formal validity. However, the law theory also focuses on other aspects of empirical to understand the legal phenomenon, we seek such elements in the works of Herbert Hart and Alf Ross. To Hart the rule of recognition’s content, that we can use to meet the validity of the right, should be measured empirically in each legal system and may also (but not necessarily incorporate moral elements. Differently, the realistic Ross theory is independent of the validity criterion and he argues that the effectiveness is verifiable by the effective application of the law by legal authorities.

  16. Neo-Fascisme, norme, literatuur: Oor Pieter Stoffberg se Die hart van ’n bond

    Directory of Open Access Journals (Sweden)

    M. de Jong

    1992-05-01

    Full Text Available In this article it is argued that Pieter Stoffberg's collection of stories, Die hart van ’n hond, forces the reader to constitute racist frames in order to interpret. Furthermore the author proposes that Kristeva's formalisation of the 'negation of negation', developed in The Revolution of Poetic Language, can theorise the textual process in these stories as a transgression in which the taboo on political rightist conservatism in a "New South Africa' is broken. To produce this transgression, the text places the reader in the position of the other, a position in which normative decision-taking is precluded. This itself could, however, constitute an ethical moment. On the basis of the Neo-Fascist aspects of Die hart van ’n hond, the article proposes a re-introduction of the ethical in literary’ discourse and critically comments on Afrikaans literary culture in this respect.

    The Belle experiment, part of a broad-based search for new physics, is a collaboration of ~400 physicists from 55 institutions across four continents. The Belle detector is located at the KEKB accelerator in Tsukuba, Japan. The Belle detector was operated at the asymmetric electron-positron collider KEKB from 1999-2010. The detector accumulated more than 1 ab-1 of integrated luminosity, corresponding to more than 2 PB of data near 10 GeV center-of-mass energy. Recently, KEK has initiated a $400 million accelerator upgrade to be called SuperKEKB, designed to produce instantaneous and integrated luminosity two orders of magnitude greater than KEKB. The new international collaboration at SuperKEKB is called Belle II. The first data from Belle II/SuperKEKB is expected in 2015. In October 2012, senior members of the Belle-II collaboration gathered at PNNL to discuss the computing and neworking requirements of the Belle-II experiment with ESnet staff and other computing and networking experts. The day-and-a-half-long workshop characterized the instruments and facilities used in the experiment, the process of science for Belle-II, and the computing and networking equipment and configuration requirements to realize the full scientific potential of the collaboration's work.

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published a supplement to this issue featuring the new Clinical Practice Guideline: Bell's Palsy. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 11 recommendations developed encourage accurate and efficient diagnosis and treatment and, when applicable, facilitate patient follow-up to address the management of long-term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. There are myriad treatment options for Bell's palsy; some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, there are numerous diagnostic tests available that are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have an unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy.

    Bell's theorem proves the existence of entangled quantum states with no classical counterpart. An experimental violation of Bell's inequality demands simultaneously high fidelities in the preparation, manipulation and measurement of multipartite quantum entangled states, and provides a single-number benchmark for the performance of devices that use such states for quantum computing. We demonstrate a Bell/ Clauser-Horne-Shimony-Holt inequality violation with Bell signals up to 2.70(9), using the electron and the nuclear spins of a single phosphorus atom embedded in a silicon nanoelectronic device. Two-qubit state tomography reveals that our prepared states match the target maximally entangled Bell states with >96% fidelity. These experiments demonstrate complete control of the two-qubit Hilbert space of a phosphorus atom and highlight the important function of the nuclear qubit to expand the computational basis and maximize the readout fidelity.

  20. "A hint of it, with initials": adultery, textuality and publicity in Jane Austen's Lady Susan.

    Science.gov (United States)

    Russell, Gillian

    2010-01-01

    In spite of Jane Austen's professed “eye” for an adulteress, comparatively little attention has been paid to adultery and divorce as themes and contexts of her fiction. Her unpublished epistolary novel Lady Susan has a distinctive status in Austen's oeuvre, recognized as being exemplary of her “style” and yet atypical of her later achievement. A neglected context for the novel is the extensive reporting of adultery trials in contemporary print culture and the moral panic concerning adultery in the 1780s and 1790s, focusing initially on the adulteress as the brazen woman of fashion and later as a figure of sentimentalized abjection. A particularly notorious case, that involving Lady Henrietta Grosvenor and George III's brother, the Duke of Cumberland, is directly alluded to in Lady Susan. The textual strategies of adultery trial literature, particularly its emphasis on indirection through the use of detail or “hint”, had a long-term influence on the development of Austen's fiction and her positioning of herself as a professional writer after the 1790s.

  1. HardwareSoftware Co-design for Heterogeneous Multi-core Platforms The hArtes Toolchain

    CERN Document Server

    2012-01-01

    This book describes the results and outcome of the FP6 project, known as hArtes, which focuses on the development of an integrated tool chain targeting a heterogeneous multi core platform comprising of a general purpose processor (ARM or powerPC), a DSP (the diopsis) and an FPGA. The tool chain takes existing source code and proposes transformations and mappings such that legacy code can easily be ported to a modern, multi-core platform. Benefits of the hArtes approach, described in this book, include: Uses a familiar programming paradigm: hArtes proposes a familiar programming paradigm which is compatible with the widely used programming practice, irrespective of the target platform. Enables users to view multiple cores as a single processor: the hArtes approach abstracts away the heterogeneity as well as the multi-core aspect of the underlying hardware so the developer can view the platform as consisting of a single, general purpose processor. Facilitates easy porting of existing applications: hArtes provid...

  2. A qualitative evaluation of DAFNE-HART: A psychoeducational programme to restore hypoglycaemia awareness.

    2015-08-01

    Impaired awareness of hypoglycaemia (IAH) in people with type 1 diabetes is a dangerous condition that is associated with a six-fold greater risk of severe hypoglycaemia than for people with awareness. A new psychoeducational programme, DAFNE-HART, has been specifically designed to address persistent IAH. The initial pilot showed promising outcomes including fewer hypoglycaemic episodes and improved hypoglycaemia awareness. This aim of this paper is to report the development and qualitative evaluation of DAFNE-HART from participant interviews. DAFNE-HART incorporates diabetes education with two psychological approaches that have demonstrated efficacy in long-term health conditions: motivational interviewing and cognitive behaviour therapy. The course, delivered across two UK locations included both group and individual support over a 6-week period facilitated by DAFNE educators, trained and supervised by a clinical psychologist. Semi-structured interviews were conducted with 19 participants immediately after their courses and the interviews were analysed using grounded theory. Five main themes emerged which describe the behavioural changes people made to their diabetes management, the development of new attitudes and beliefs, their experiences of regaining hypoglycaemia cues, reactions to the course format and the significance of the relationship with their care provider. Participants provide insights into how the course changed their view of IAH and led to practical changes in minimising hypoglycaemia. Integration of psychological techniques into diabetes education can address the cognitive and motivational barriers to restoring awareness and optimal diabetes management. It is suggested that further research is needed to evaluate this programme in a larger sample, over a longer time frame. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    In the Spring of 2016, the UK-based arts organisation Kaleider and the EU-funded FP7 climate services project EUPORIAS made an International Commission Call inviting artists to submit ideas for playable artworks to be debuted at the EUPORIAS General Assembly at the Met Office in October 2016. We received over 60 applications worldwide and were overwhelmed with the quality of ideas. We commissioned Roop Johnstone from RAMP Ceramics to create his exquisite playable artwork - BellHouse. BellHouse is a playful, interactive sound sculpture that translated the non-verbal communication of the delegates presenting at the EUPORIAS General Assembly into the chimes of 35 bells in an opened sided house. A motion capture system devised by the Met Office Informatics Lab activated striking mechanisms associated with each ceramic bell generating a continuous chiming whilst each speaker at the 250 delegate conference presented their research. BellHouse also invited Met Office scientists to interact with it through their work. Some of our favourite data translated into sound included Mt. Etna's volcanic plumes, the European drought of 1976, the solar wind, 250 years of English and Welsh temperature and precipitation anomalies and reanalysis data based on citizen science. Here we present an exploration of the why and how of BellHouse, outlining some of our reflections on its effectiveness alongside its legacy.

    The scientific goals of the BELLE experiment continue to be of great interest. The large number of papers during the past year that identify measurements that can be done with BELLE reflects the considerable interest in the theoretical community in these physics issues. This is also demonstrated by the approval during the past year of two major B physics projects: the BaBar experiment at SLAC and the HERAB experiment at DESY. Both projects have schedules that put them into direct competition with BELLE for the important goal of testing the KM predictions for CP violations in B meson decays. Other projects addressing this physics are planned for the Tevatron collider and have been proposed both for the LHC and RHIC. The BELLE collaboration remains committed to its goal of being the first group to provide conclusive evidence either confirming or refuting the KM model. The year 1995 was an exciting time for the BELLE experiment. All of the major technology choices were finalized and a final detector configuration has been established. Continued R and D has resulted in improved performance expectations for a number of detector subsystems. The procurement of materials for major subsystems is underway and construction of long leadtime items has started. A construction schedule has been established and an integration strategy is being developed. This report describes the status of BELLE with an emphasis on progress since the last LCPAC meeting in January 1995. (J.P.N.). 90 refs.

    Full Text Available A brief overview of the main works and achievements of Alexander Graham Bell, an educated teacher for the hard of hearing and public figure, author of 30 US patents, is mainly given in the field of telephony and sound recording and reproduction. Biographical information about the Bell family, as well as some interesting facts from his life and activities are given. Scotsman by birth, A. Bell from his youthful years was carried away by the acoustic features of the human voice apparatus and devoted his entire life to teaching the deaf to the perception of oral speech. The first success in this field Bell reached, opening a private school for the deaf in Boston. Bell's creation of the phone was the result of his attempts to facilitate communication with the hard-of-hearing and led to the development of mass communications technology around the world. Alexander Bell is also known for his achievements in the design of hydroplanes, hydrofoils and as one of the founders of the popular magazine National Geographic. He was awarded many honorable awards and academic titles.

    Full Text Available The dynamic of the juridical epistemology of Islamic economy in Indonesia passed through four phases, i.e. sharī‘ah, fiqh, qānūn, and qad\\ā’. The first two phases have normative doctrinal characteristics while the last two show positive legal formal characteristics. The transformation of Islamic economic law started at the level of normative moral doctrinal to the level of legal formal. It has a methodological spirit which is closely related to the theory of legal transition by H.L.A. Hart. According to Hart, the transition from moral to law involves two concepts. First, primary rules which define the moral values embraced by the people. Second, secondary rules which modify and dynamite the primary rules to be legal binding for all the people. In this case, state authority is required to execute the rules. In Hart’s perspective on the transition of law, sharī‘ah and fiqh are the rules of etiquette and obligation. Meanwhile, qānūn, and qad\\ā’ are the rules of recognition, rules of change, and rules of adjudication. In the transition of law, there is an interconnection between law and Islamic economy sustainably, professionally, and proportionally.

    2015-05-01

    Full Text Available The aim of the paper is to analyse the novel Angels and Insects by Antonia Susan Byatt in terms of intertextual references. The author’s assumptions are based on the categorisation by Ryszard Nycz, who distinguishes three major types of intertexts: text versus text, text versus literary genre and text versus mimesis. Byatt uses intertextuality mainly to comment on the role of nature in the world, as well as to enhance the importance of human relationship with nature. Moreover, the writer moves towards literary criticism, discussing poems by famous artists, such as Alfred Tennyson or John Milton. In this way, the novel by Byatt is also an example of metafiction. All the narration techniques used by the English writer make the novel a typically postmodern work of art.

  13. Intermittent large amplitude internal waves observed in Port Susan, Puget Sound

    Harris, J. C.; Decker, L.

    2017-07-01

    A previously unreported internal tidal bore, which evolves into solitary internal wave packets, was observed in Port Susan, Puget Sound, and the timing, speed, and amplitude of the waves were measured by CTD and visual observation. Acoustic Doppler current profiler (ADCP) measurements were attempted, but unsuccessful. The waves appear to be generated with the ebb flow along the tidal flats of the Stillaguamish River, and the speed and width of the resulting waves can be predicted from second-order KdV theory. Their eventual dissipation may contribute significantly to surface mixing locally, particularly in comparison with the local dissipation due to the tides. Visually the waves appear in fair weather as a strong foam front, which is less visible the farther they propagate.

  16. Beyond Bell's theorem: realism and locality without Bell-type correlations.

    Science.gov (United States)

    De Zela, F

    2017-11-06

    The long-lasting view of entanglement as the characteristic trait of quantum mechanics has been recently challenged by experimental demonstrations of non-quantum entanglement. This motivates a review of the meaning of Bell violations, which have been widely taken to prove the impossibility of a realistic interpretation of quantum mechanics and as a manifestation of its non-local character. This work provides new theoretical evidence for the need of reviewing the meaning of Bell violations, especially when they occur outside the quantum framework. We present a local-realistic model that reproduces quantum predictions concerning Bell tests. We claim that local-realism is fully compatible with correlations that are not of the Bell type and therefore lie outside the scope of Bell's theorem. Most experimental Bell tests involve either spin vectors spanning the Bloch sphere or Stokes vectors spanning the Poincaré sphere. A suitable statistical tool that allows assessing correlations between vectors is given by inner-product-type correlations. Using them, it is possible to reproduce quantum predictions for all Bell states, thereby explaining experimental results of Bell tests within a local-realistic framework.

    The bunching of two single photons on a beam splitter is a fundamental quantum effect, first observed by Hong, Ou, and Mandel. It is a unique interference effect that relies only on the photons’ indistinguishability and not on their relative phase. We generalize this effect by demonstrating the bunching of two Bell states, created in two passes of a nonlinear crystal, each composed of two photons. When the two Bell states are indistinguishable, phase-insensitive destructive interference prevents the outcome of fourfold coincidence between the four spatial-polarization modes. For certain combinations of the two Bell states, we demonstrate the opposite effect of antibunching. We relate this result to the number of distinguishable modes in parametric down-conversion.

  20. ["Bell-striking" Saying of Acupuncture Therapy].

    2017-04-25

    As an analogy, a prototype of "bell-striking" is proposed in the present paper for exploring the basic properties, major elements, and potential mechanisms of acupuncture stimulation. On the strength of analysis on the physiological basis of acupuncture effect, several fundamental aspects of acupuncture are summarized as a) the body-surface stimulating characters, b) general and local effects, and c) triggering the auto-regulative function of the organism, which mimics the "bell-striking" response. Namely, when stroke, bell will chime, otherwise, chiming will not be heard. During analyzing special contents of acupuncture theory, its formative background should not be separated, and it is improper to take, modern medical theory of the human body as the guiding thinking way for researching the ancient Chinese medical literature.

  1. Original hypothesis: Extracorporeal shockwaves as a homeostatic autoimmune restorative treatment (HART) for Type 1 diabetes mellitus.

    Science.gov (United States)

    Craig, Kenneth; d'Agostino, Cristina; Poratt, Daniel; Walker, Marjorie

    2014-09-01

    Mononuclear invasion of Langerhans islet and the ensuing insulitis triggers signal-transduction for the autoimmune mediated pancreatic beta-cell (β-cell) apoptosis that severely disrupts insulin production resulting in hyperglycemia associated with Type-1 diabetes (T1DM). Today extensive global research is being conducted to eliminate the need for insulin, and even prevent or find a cure for T1DM. The multifactorial combination of autoimmune dysfunction, Langerhans islet hypoxia, and bio-chemical disruption are seen to be contributory factors for β-cell destruction and the consequential disruption to insulin production. Regeneration of β-cells back to physiological levels may restore homeostatic insulin levels, reversing T1DM. Evidence suggests that there are still functioning pancreatic β-cells even in long standing T1DM providing the potential for their regeneration. Although the exact mechanism of extracorporeal shockwaves (ESW) is yet to be fully elucidated, it is seen to influence a complex spectrum of bio-chemical, cellular and neuronal functions (i.e. suppression of pro-inflammatory immune response, improved tissue hemodynamics, anti-microbial properties, and the induction of progenitor cell expression including proangiogenic factors and nitric oxide syntheses). The rationale for the use of ESW as a therapeutic modality in this instance is attributed to its restorative properties and safety profile demonstrated in urology, cardiology, chronic wounds, osteogenesis, complex pain syndromes, and tendinopathies. ESW may restore autoimmune homeostasis creating a suitable environment for pancreatic β-cell proliferation which in-turn may significantly increase or normalize endogenous insulin secretion reducing or totally eliminating dependency of exogenous insulin. The devastating complications, morbidity and mortality associated with T1DM warrants the exploration of homeostatic autoimmune restorative treatment (HART) modalities that may partially or fully

    The Hart Peak 1:24,000-scale quadrangle is located about 12 km southwest of Searchlight, Nevada, comprehending the eastern part of the Castle Peaks, California, and most of the Castle Mountains and the northwestern part of the Piute Range, in California and Nevada. The Castle Peaks area constitutes the northeasternmost part of the northeast-trending New York Mountains. The Castle Mountains straddle the California-Nevada State line between the Castle Peaks and north-trending Piute Range. The southern part of the Piute Range, near Civil War-era Fort Piute, adjoins Homer Mountain mapped by Spencer and Turner (1985). Adjacent and nearby 1:24,000-scale quadrangles include Castle Peaks, East of Grotto Hills, Homer Mountain, and Signal Hill, Calif.; also Tenmile Well and West of Juniper Mine, Calif. and Nev. The oldest rocks in the Hart Peak quadrangle are Early Proterozoic gneiss and foliated granite that crop out in the northern part of the quadrangle on the eastern flank of the Castle Peaks and in the central Castle Mountains (Wooden and Miller, 1990). Paleozoic rocks are uncommon and Mesozoic granitic rocks are not found in the map area. The older rocks are overlain nonconformably by several km of Miocene volcanic deposits, which accumulated in local basins. Local dikes and domes are sources of most Miocene eruptive units; younger Miocene intrusions cut all the older rocks. Upper Miocene to Quaternary gravel deposits interfinger with the uppermost volcanic flows; the contact between volcanic rocks and the gravel deposits is unconformable locally. Canyons and intermontane valleys contain dissected Quaternary alluvialfan deposits that are mantled by active drainage and alluvial fan detritus.

  3. The probabilistic origin of Bell's inequality

    Krenn, Guenther

    1994-01-01

    The concept of local realism entails certain restrictions concerning the possible occurrence of correlated events. Although these restrictions are inherent in classical physics they have never been noticed until Bell showed in 1964 that general correlations in quantum mechanics can not be interpreted in a classical way. We demonstrate how a local realistic way of thinking about measurement results necessarily leads to limitations with regard to the possible appearance of correlated events. These limitations, which are equivalent to Bell's inequality can be easily formulated as an immediate consequence of our discussion.

    Full Text Available The author interprets Susan Silas' Helmbrechts walk (1998-2003, a unique series of forty-five photographs and supplementing visual and textual materials collected during the walk along the route of two hundred and twenty-five miles. The walk repeats the route which in 1945 had to undertake women prisoners from the concentration camp in Helmbrechts near Flossenbürg in their death march to Prachatice in Czech Republic. The pictures Silas takes, the people she meets, and finally the trees, the very materiality of the road become the factors of creating her own, individual memory of the event from the past. Silas selects an object from "the margins of the Holocaust" – a forgotten event that she re-presents by reacting to contemporary objects placed along the route of the event. Silas' work offers an opportunity to critically review the concept of memory landscapes (where is memory located in a landscape? and the phenomenon of dark tourism (is following in the footsteps of the prisoners a kind of pilgrimage, tourism, or therapy?. Silas problematises the question of memory, as well as examines different kinds of non-memory. Her camera is directed at locations that can be termed "the non-sites of memory."

  9. Peripheral nerve involvement in Bell's palsy

    1984-12-01

    Full Text Available A group of patients with Bell's palsy were studied in order to disclose the presence of subclinical peripheral nerve involvement. 20 patients, 8 male and 12 female, with recent Bell's palsy as their unique disease were examined, in all cases other causes of polyneuropathy were ruled out. Patients were investigated with CSF examination, facial nerve latencies in the affected and in the sound sides, and maximal motor nerve conduction velocities, as well as motor terminal latencies from the right median and peroneal nerves. CSF laboratory examination was normal in all cases. Facial nerve latencies were abnormal in all patients in the affected side, and they differed significantly from those of control group in the clinically sound side. Half of the patients showed abnormal values in the maximal motor nerve conduction velocities and motor terminal latencies of the right median and peroneal nerves. These results agree with previous reports which have pointed out that other cranial nerves may be affected in Bell's palsy. However, we have found a higher frequency of peripheral nerve involvement in this entity. These findings, support the hypothesis that in some patients Bell's palsy is the component of a more widespread disease, affecting other cranial and peripheral nerves.

    2011-12-01

    Full Text Available The article deals with heroines of William Faulkner's novels Light in August, Absalom, Absalom!, The Sound and the Fury, The Unvanquished, The Town and his short story "A Rose for Emily". The Southern belle features as a recurring character in Faulkner's fiction, her fragility, modesty, weakness yet strength, beauty, sincerity, generous nature, status and her fall from innocence comprise her central characteristics. Confronted with various expectations of Southern society and with the hardships of war, the belle is faced with many obstacles and challenges. Faulkner's heroines face a wide array of problems that prevent them from being and/or remaining a Southern belle. Let us name a few: Lena's inappropriate social status, Joanna's wrong roots, Mrs. Hightower's inability to fulfill her duties as the minister's wife, Ellen's miserable marriage, Judith's sad love life, Rosa's feelings of inferiority and humiliation, Mrs. Compson's failure as a mother, Caddy's weak rebellion against male convention, Drusilla's male characteristics, Linda's unrequited love and Emily's dark secret, to name a few. Through these characters and their destinies Faulkner shows a decaying South whose position has changed considerably over the years. Can the Southern belle save it? Can she save herself?

    Purpose: To report the long-term results of the ARO 95-06 randomized trial comparing hyperfractionated accelerated chemoradiation with mitomycin C/5-fluorouracil (C-HART) with hyperfractionated accelerated radiation therapy (HART) alone in locally advanced head and neck cancer. Patients and Methods: The primary endpoint was locoregional control (LRC). Three hundred eighty-four patients with stage III (6%) and IV (94%) oropharyngeal (59.4%), hypopharyngeal (32.3%), and oral cavity (8.3%) cancer were randomly assigned to 30 Gy/2 Gy daily followed by twice-daily 1.4 Gy to a total of 70.6 Gy concurrently with mitomycin C/5-FU (C-HART) or 16 Gy/2 Gy daily followed by twice-daily 1.4 Gy to a total dose of 77.6 Gy alone (HART). Statistical analyses were done with the log-rank test and univariate and multivariate Cox regression analyses. Results: The median follow-up time was 8.7 years (95% confidence interval [CI]: 7.8-9.7 years). At 10 years, the LRC rates were 38.0% (C-HART) versus 26.0% (HART, P=.002). The cancer-specific survival and overall survival rates were 39% and 10% (C-HART) versus 30.0% and 9% (HART, P=.042 and P=.049), respectively. According to multivariate Cox regression analysis, the combined treatment was associated with improved LRC (hazard ratio [HR]: 0.6 [95% CI: 0.5-0.8; P=.002]). The association between combined treatment arm and increased LRC appeared to be limited to oropharyngeal cancer (P=.003) as compared with hypopharyngeal or oral cavity cancer (P=.264). Conclusions: C-HART remains superior to HART in terms of LRC. However, this effect may be limited to oropharyngeal cancer patients.

    Full Text Available Throughout history of thought, there have been many views about the women, their status in society, their struggle with patriarchy, and inequality  applied to them in all areas. There are different ways of oppression on women, such as confinement to home, inequality in wages between both sexes.  However, few scholars have written and declared their own views about how the patriarchal world and companies form women as they wish. Susan Bordo is one of  the most outstanding and distinguished feminist writers in the world who focuses on  how patriarchal capitalist understanding works on women’s body in terms of weight and weakness. According to Susan Bordo, male dominated capital world decides on women about what to wear and what to eat and women try to lose weight to be in the form men wish. State of  starving all the time leads to an illness called anorexia. The writer bases her views on the thoughts of literary critic and thinker, Foucault. The  objective of this article is to help the readers understand Susan Bordo’s views and analyse her impressive work; Unbearable Weight: Feminism, Western Culture and  the Body  and make her known in academic world.

    Full Text Available Autorka interpretuje pracę Susan Silas Helmbrechts walk (1998-2003, szczególny cykl czterdziestu pięciu zdjęć i dołączonych do nich materiałów wizualnych oraz tekstowych zbudowany podczas przejścia trasy dwustu dwudziestu pięciu mil, które w 1945 roku musiały przebyć kobiety pędzone w marszu śmierci z Helmbrecht koło Flossenbürga do czeskich Prachatic. Wykonywane zdjęcia, napotykani ludzie, w końcu – drzewa, sama materialność drogi stają się czynnikami wytwarzania własnej, indywidualnej pamięci wydarzenia sprzed lat. Silas wybiera szczególny obiekt "z marginesów Zagłady" – zapomniane zdarzenie, które przedstawia obserwując współczesne obiekty położone wzdłuż trasy tego zdarzenia. Praca Silas pozwala przyjrzeć się krytycznie koncepcji memory landscapes (gdzie w krajobrazie umiejscawia się pamięć? i zjawisku dark tourism (czy podążanie śladami więźniarek to pielgrzymka, turystyka czy terapia?. Silas problematyzuje nie tylko kwestię pamięci, bada również rodzaje nie-pamiętania. Jej kamera zostaje zwrócona ku lokalizacjom, które można nazwać "nie-miejscami pamięci".

    2017-12-01

    THE Genetics Society of America's (GSA) George W. Beadle Award honors individuals who have made outstanding contributions to the community of genetics researchers and who exemplify the qualities of its namesake. The 2017 recipient is Susan A. Gerbi, who has been a prominent leader and advocate for the scientific community. In the course of her research on DNA replication, Gerbi helped develop the method of Replication Initiation Point (RIP) mapping to map replication origins at the nucleotide level, improving resolution by two orders of magnitude. RIP mapping also provides the basis for the now popular use of λ-exonuclease to enrich nascent DNA to map replication origins genome-wide. Gerbi's second area of research on ribosomal RNA revealed a conserved core secondary structure, as well as conserved nucleotide elements (CNEs). Some CNEs are universally conserved, while other CNEs are conserved in all eukaryotes but not in archaea or bacteria, suggesting a eukaryotic function. Intriguingly, the majority of the eukaryotic-specific CNEs line the tunnel of the large ribosomal subunit through which the nascent polypeptide exits. Gerbi has promoted the fly Sciara coprophila as a model organism ever since she used its enormous polytene chromosomes to help develop the method of in situ hybridization during her Ph.D. research in Joe Gall's laboratory. The Gerbi laboratory maintains the Sciara International Stock Center and manages its future, actively spreading Sciara stocks to other laboratories. Gerbi has also served in many leadership roles, working on issues of science policy, women in science, scientific training, and career preparation. This is an abridged version of the interview.

  4. HART Y LA CONFIGURACIÓN DEL ESTADO JURISDICCIONAL. UNA LECTURA SCHMITTIANA

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available El artículo sugiere la plausibilidad en el contexto colombiano contemporáneo de la hipótesis según la cual la recepción de las tesis de la discrecionalidad judicial planteadas por Herbert Hart constituyen la base de la configuración de lo que Carl Schmitt denominó el Estado jurisdiccional. El trabajo de investigación recurre a la definición conceptual tanto del Estado jurisdiccional como del papel discrecional que ejerce el juez según los presupuestos hartianos, y que en América Latina ha tenido una fuerte influencia en el papel del juez constitucional, para concluir que en el marco de los actuales tribunales constitucionales la discrecionalidad judicial no solo ha conllevado un conflicto interno en la clásica división tripartita del poder público sino, además, la configuración de una forma de Estado donde los grandes problemas sociales, políticos y económicos son decididos por individuos que ejercen una función política pero que carecen de una responsabilidad del mismo tenor.

    1987-05-01

    Full Text Available The autobiographical manner of presentation of Maarten 't Hart’s stories has the consequence that the narrative distance is particularly small - so that the effect on the reader is greater, and he is strongly addressed by the message of each story. This gives rise to the fact that the relevant stories can be evaluated not only on the bais of the literary aesthetic qualities, but also on the basis of lifeview. The three stories, De zaterdagvliegers, Ouderlingenbezoek and De wine nacht consistently reveal a sustained line of emotional tension, and style and structural means are well applied to support the thematic concerns. In De witte nacht especially an exceptional measure of textural density is obtained and the story reveals a close coherence. In the ethical sense the existential sense of life which is revealed by the stories as well as the one-sided characterisation of the representatives of the Christian faith is obtrusive. These two characteristics of his work reveal aparticular awareness of the spirit of the time in which ’t Hart is caught and explains to some extent why he is one of the most widely-read Dutch authors since 1945.

    The Belle spectrometer was designed for studies of B meson decays at an asymmetric e sup + e sup - collider operating at the UPSILON(4S) resonance. One of its crucial components, a silicon vertex detector (SVD), is placed just outside a cylindrical beryllium beam-pipe. After a year of Belle operation an upgraded version of SVD was installed during the regular summer shut-down. The new SVD follows the same design, with a few important improvements. Rad-soft readout electronics was replaced by rad-tolerant one, allowing for longer lifetime of the detector. A new radiation and temperature monitoring system was developed and implemented. A saw-shaped inner surface was introduced in the beam-pipe to prevent potential synchrotron radiation damage. The upgraded detector started operating successfully in October 2000.

  7. A Modest View of Bell's Theorem

    CERN Document Server

    Boughn, Stephen

    2016-01-01

    In the 80 years since the seminal Einstein, Podolsky, and Rosen (EPR) paper, physicists and philosophers have mused about the `spooky action at a distance' aspect of quantum mechanics that so bothered Einstein. In his formal analysis of EPR-type entangled quantum states, Bell (1964) concluded that any hidden variable theory designed to reproduce the predictions of quantum mechanics must necessarily be nonlocal and allow superluminal interactions. This doesn't immediately imply that nonlocality is a characteristic feature of quantum mechanics let alone a fundamental property of nature; however, many physicists and philosophers of science do harbor this belief. Experts in the field often use the term `nonlocality' to designate particular non-classical aspects of quantum entanglement and do not confuse the term with superluminal interactions. However, many physicists seem to take the term more literally. I endeavor to disabuse the latter of this notion by emphasizing that the correlations of Bell-type entangleme...

    2015-07-01

    The construction and commissioning of the Belle II Vertex Detector (VXD) is a huge endeavor involving a large number of valuable components. Both subsystems PXD (Pixel Detector) and SVD (Silicon Vertex Detector) deploy a large number of sensors, readout electronic parts and mechanical elements. These items are scattered around the world at many institutes, where they are built, measured and assembled. One has to keep track of measurement configurations and results, know at any time the location of the sensors, their processing state, quality, where they end up in an assembly, and who is responsible. These requirements call for a flexible and extensive database which is able to reflect the processes in the laboratories and the logistics between the institutes. This talk introduces the database requirements of a physics experiment using the PXD construction workflow as a showcase, and presents an overview of the database ''HephyDb'', which is used by the groups constructing the Belle II VXD.

  9. Infinite violation of Bell inequalities in inflation

    Kanno, Sugumi; Soda, Jiro

    2017-10-01

    We study the violation of Bell-Mermin-Klyshko (BMK) inequalities in initial quantum states of scalar fields in inflation. We show that the Bell inequality is maximally violated by the Bunch-Davies vacuum which is a two-mode squeezed state of a scalar field. However, we find that the violation of the BMK inequalities does not increase with the number of modes to measure. We then consider a non-Bunch-Davies vacuum expressed by a four-mode squeezed state of two scalar fields. Remarkably, we find that the violation of the BMK inequalities increases exponentially with the number of modes to measure. This shows that the BMK inequalities are useful to classify the initial quantum state of the Universe.

  13. Aiming for the theoretical limit of sensitivity of Bonse-Hart USANS instruments

    Science.gov (United States)

    Carpenter, John M.; Agamalian, Michael

    2010-11-01

    The basis of the Double-Crystal Diffractometer (DCD), used for ultra-small angle neutron scattering (USANS), is that the reflectivity function is very near 1.0 for |y| 1, eventually decreasing as y -2. In the Bonse-Hart multi-bounce crystal the reflectivity function R(y) transforms into Rm(y) and in the wings, for large |y|, theoretically decreases as y-2m after m consecutive Bragg reflections inside the channel-cut crystal. Here θ and θB are respectively the diffraction angle and the Bragg angle (for given wavelength) and δΘD is the width of the Darwin plateau. However, the experimental reflectivity Rmexp(y) obtained for m = 3 exceeds the theoretical prediction by over two orders of magnitude in the range of the far wings, which creates limitations for USANS studies of weakly scattering objects. We used the pulsed-source neutron time-of-flight (TOF) technique to study this discrepancy in more detail. Two identical Si(111) crystals, a slab-shaped single-bounce and a channel-cut triple-bounce, were measured at the nominal Bragg angle θB = 24.4o in the TOF powder diffractometer GPPD at IPNS, in the range 0.2 beam lines except by the use of highly curved neutron guides. However, the TOF-USANS instrument, which is currently under construction at SNS, allows separation of the orders of Bragg reflections and the residual TDS in time-of-flight and thus the discovered parasitic effect cannot compromise its sensitivity. Thus, we expect to approach the theoretical limit of sensitivity for the SNS TOF-USANS instrument.

    The KEKB machine and the Belle experiment in Tsukuba (Japan) are now undergoing an upgrade, leading to an ultimate luminosity of 8×10{sup 35}cm{sup −2}s{sup −1} in order to measure rare decays in the B system with high statistics. The previous vertex detector cannot cope with this 40-fold increase of luminosity and thus needs to be replaced. Belle II will be equipped with a two-layer Pixel Detector surrounding the beam pipe, and four layers of double-sided silicon strip sensors at higher radii than the old detector. The Silicon Vertex Detector (SVD) will have a total sensitive area of 1.13m{sup 2} and 223,744 channels—twice as many as its predecessor. All silicon sensors will be made from 150 mm wafers in order to maximize their size and thus to reduce the relative contribution of the support structure. The forward part has slanted sensors of trapezoidal shape to improve the measurement precision and to minimize the amount of material as seen by particles from the vertex. Fast-shaping front-end amplifiers will be used in conjunction with an online hit time reconstruction algorithm in order to reduce the occupancy to the level of a few percent at most. A novel “Origami” chip-on-sensor scheme is used to minimize both the distance between strips and amplifier (thus reducing the electronic noise) as well as the overall material budget. This report gives an overview on the status of the Belle II SVD and its components, including sensors, front-end detector ladders, mechanics, cooling and the readout electronics.

    Rafael Lazzarotto Simioni

    2016-12-01

    Full Text Available A proposta do trabalho reside em explorar o conceito da legitimidade no marco teórico de Herbert Lionel Adolphus Hart. A questão da legitimidade está na base do Estado Democrático de Direito e do convívio social, sendo ao mesmo tempo questão complexa e de suma importância, abordada em diversas hipóteses e teorias, mas sem nunca uma resposta definitiva. Observa-se inicialmente a própria necessidade de fundamentação da legitimidade e sua relação com o conceito de justiça. Prossegue-se analisando a visão de Hart sobre regras primárias e secundárias, e o papel das regras de reconhecimento como fator de legitimidade do ordenamento jurídico. Por último, estuda-se a questão da derrotabilidade das regras jurídicas, fenômeno em que regras retiram a efetividade de outras, como é o caso do instituto da legítima defesa. Conclui-se que, apesar de não ser possível, ao menos no momento, encontrar uma resposta definitiva para a pergunta da legitimidade, Hart nos oferece uma visão sofisticada, baseada em fatos sociais, sem necessidade de construções hipotéticas, tornando possível identificar, através de regras de reconhecimento, a legitimidade embutida no sistema.

    2017-10-01

    Over the last seven years the software stack of the next generation B factory experiment Belle II has grown to over one million lines of C++ and Python code, counting only the part included in offline software releases. There are several thousand commits to the central repository by about 100 individual developers per year. To keep a coherent software stack of high quality that it can be sustained and used efficiently for data acquisition, simulation, reconstruction, and analysis over the lifetime of the Belle II experiment is a challenge. A set of tools is employed to monitor the quality of the software and provide fast feedback to the developers. They are integrated in a machinery that is controlled by a buildbot master and automates the quality checks. The tools include different compilers, cppcheck, the clang static analyzer, valgrind memcheck, doxygen, a geometry overlap checker, a check for missing or extra library links, unit tests, steering file level tests, a sophisticated high-level validation suite, and an issue tracker. The technological development infrastructure is complemented by organizational means to coordinate the development.

    Delivered at Trieste on the occasion of the 25th Anniversary of the International Centre for Theoretical Physics, 2 November 1989 The video of this lecture is available here. Please see the PDF for the transcript of the lecture. General remarks by Angelo Bassi and GianCarlo Ghirardi During the autumn of 1989 the International Centre for Theoretical Physics, Trieste, celebrated the 25th anniversary of its creation. Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5 10 September 2005, it occurred to us that this lecture, which has never been published, might represent an

    2017-10-01

    The Belle II experiment at KEK is preparing for first collisions in 2017. Processing the large amounts of data that will be produced will require conditions data to be readily available to systems worldwide in a fast and efficient manner that is straightforward for both the user and maintainer. The Belle II conditions database was designed with a straightforward goal: make it as easily maintainable as possible. To this end, HEP-specific software tools were avoided as much as possible and industry standard tools used instead. HTTP REST services were selected as the application interface, which provide a high-level interface to users through the use of standard libraries such as curl. The application interface itself is written in Java and runs in an embedded Payara-Micro Java EE application server. Scalability at the application interface is provided by use of Hazelcast, an open source In-Memory Data Grid (IMDG) providing distributed in-memory computing and supporting the creation and clustering of new application interface instances as demand increases.

    Randomness is a fundamental feature of nature and a valuable resource for applications ranging from cryptography and gambling to numerical simulation of physical and biological systems. Random numbers, however, are difficult to characterize mathematically, and their generation must rely on an unpredictable physical process. Inaccuracies in the theoretical modelling of such processes or failures of the devices, possibly due to adversarial attacks, limit the reliability of random number generators in ways that are difficult to control and detect. Here, inspired by earlier work on non-locality-based and device-independent quantum information processing, we show that the non-local correlations of entangled quantum particles can be used to certify the presence of genuine randomness. It is thereby possible to design a cryptographically secure random number generator that does not require any assumption about the internal working of the device. Such a strong form of randomness generation is impossible classically and possible in quantum systems only if certified by a Bell inequality violation. We carry out a proof-of-concept demonstration of this proposal in a system of two entangled atoms separated by approximately one metre. The observed Bell inequality violation, featuring near perfect detection efficiency, guarantees that 42 new random numbers are generated with 99 per cent confidence. Our results lay the groundwork for future device-independent quantum information experiments and for addressing fundamental issues raised by the intrinsic randomness of quantum theory.

    Full Text Available Hirshfeld atom refinement (HAR is a novel X-ray structure refinement technique that employs aspherical atomic scattering factors obtained from stockholder partitioning of a theoretically determined tailor-made static electron density. HAR overcomes many of the known limitations of independent atom modelling (IAM, such as too short element–hydrogen distances, r(X—H, or too large atomic displacement parameters (ADPs. This study probes the accuracy and precision of anisotropic hydrogen and non-hydrogen ADPs and of r(X—H values obtained from HAR. These quantities are compared and found to agree with those obtained from (i accurate neutron diffraction data measured at the same temperatures as the X-ray data and (ii multipole modelling (MM, an established alternative method for interpreting X-ray diffraction data with the help of aspherical atomic scattering factors. Results are presented for three chemically different systems: the aromatic hydrocarbon rubrene (orthorhombic 5,6,11,12-tetraphenyltetracene, a co-crystal of zwitterionic betaine, imidazolium cations and picrate anions (BIPa, and the salt potassium hydrogen oxalate (KHOx. The non-hydrogen HAR-ADPs are as accurate and precise as the MM-ADPs. Both show excellent agreement with the neutron-based values and are superior to IAM-ADPs. The anisotropic hydrogen HAR-ADPs show a somewhat larger deviation from neutron-based values than the hydrogen SHADE-ADPs used in MM. Element–hydrogen bond lengths from HAR are in excellent agreement with those obtained from neutron diffraction experiments, although they are somewhat less precise. The residual density contour maps after HAR show fewer features than those after MM. Calculating the static electron density with the def2-TZVP basis set instead of the simpler def2-SVP one does not improve the refinement results significantly. All HARs were performed within the recently introduced HARt option implemented in the Olex2 program. They are easily

    2016-01-01

    After the major success of B-factories to establish the CKM mechanism and its proven potential to search for new physics, the Belle II experiment will continue exploring the physics at the flavor frontier over the next years. Belle II will collect 50 times more data than its predecessor, Belle, and allow for various precision measurements and searches of rare decays and particles. This paper introduces the B-factory concept and the flavor frontier approach to search for new physics. It then describes the SuperKEKB accelerator and the Belle II detector, as well as some of the physics that will be analyzed in Belle II, concluding with the experiment status and schedule.

  14. John Stewart Bell and twentieth century physics vision and integrity

    Whitaker, Andrew

    2016-01-01

    John Stewart Bell (1928-1990) was one of the most important figures in twentieth-century physics, famous for his work on the fundamental aspects of the century's most important theory, quantum mechanics. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. He was able to demonstrate a contradiction between quantum theory and essential elements of pre-quantum theory - locality and causality. The book gives a non-mathematical account of Bell's relatively impoverished upbringing in Belfast and his education. It describes his major contributions to quantum theory, but also his important work in the physics of accelerators, and nuclear and elementary particle physics.

    Bell inequalities and nonlocality have been widely studied in one-dimensional quantum systems. As a kind of quantum correlation, it is expected that bipartite nonlocality should be present in quantum systems, just as bipartite entanglement does. Surprisingly, for various models, two-qubit states do not violate Bell inequalities, i.e., they are local. Recently, it is realized that the results are related to the monogamy trade-off obeyed by bipartite Bell correlations, thus it is believed that for general translation invariant systems, two-qubit states should not violate the Bell inequality [Oliveira, Europhys. Lett.EULEEJ0295-507510.1209/0295-5075/100/60004 100, 60004 (2012)]. In this Brief Report, we demonstrate that in perfect translation-invariant systems with an even number of sites, the Bell inequality can be violated. A nontrivial model is constructed to confirm the conclusion.

    Full Text Available Susan Magoffin, la jeune épouse d’un commerçant de la piste de Santa Fe, accompagna son mari en 1846 pour un voyage où la caravane suivait de près l’Armée de l’Ouest et pendant lequel elle tint un journal. Cet article traite des 37 jours que dura la pause de la caravane à Santa Fe et aborde plus spécifiquement la façon dont l’auteur appréhendait l’altérité dans un environnement inhabituel et parfois dangereux. Pour apprécier la valeur du témoignage, je combine une analyse du discours avec une évaluation statistique du contenu. La description, parfois naïve, de Santa Fe sous l’occupation américaine illustre les raisons de la guerre contre le Mexique. En tant qu’agent de la destinée manifeste, Susan Magoffin admirait le général Kearny en lui attribuant des qualités surhumaines et en participant à ses efforts de propagande. Alors qu’elle était enracinée dans sa classe et sa culture, elle voyait la population mexicaine et les Amérindiens avec un esprit ouvert bien que ses motifs pour apprendre l’espagnol, ainsi que le métier de commerçante, avaient une fonction plus prosaïque.

  18. Bell's palsy before Bell: Evert Jan Thomassen à Thuessink and idiopathic peripheral facial paralysis.

    Bell's palsy is the eponym for idiopathic peripheral facial paralysis. It is named after Sir Charles Bell (1774-1842), who, in the first half of the nineteenth century, discovered the function of the facial nerve and attracted the attention of the medical world to facial paralysis. Our knowledge of this condition before Bell's landmark publications is very limited and is based on just a few documents. In 1804 and 1805, Evert Jan Thomassen à Thuessink (1762-1832) published what appears to be the first known extensive study on idiopathic peripheral facial paralysis. His description of this condition was quite accurate. He located several other early descriptions and concluded from this literature that, previously, the condition had usually been confused with other afflictions (such as 'spasmus cynicus', central facial paralysis and trigeminal neuralgia). According to Thomassen à Thuessink, idiopathic peripheral facial paralysis and trigeminal neuralgia were related, being different expressions of the same condition. Thomassen à Thuessink believed that idiopathic peripheral facial paralysis was caused by 'rheumatism' or exposure to cold. Many aetiological theories have since been proposed. Despite this, the cold hypothesis persists even today.

    We built a data acquisition system for the Belle experiment at the KEK B-factory. The system is designed to record the signals from the detectors at 500 Hz trigger rate with a less than 10% dead time fraction. A typical event size is 30 kbyte, which corresponds to a data transfer rate of 15 Mbyte/s. Main components are two kinds of detector readout systems, an event builder, an online computer farm and a data storage system. The system has been reliably in operation at the design performance for a half year. We have completed cosmic-ray data taking for 2.5 months and have started physics data taking on Jun. 1, 1999.

    We renewed the data acquisition system for the Belle experiment. Previous data acquisition system, which has been used since December 1998, did not have level 2 trigger facility. To improve the data reduction factor and total throughput, we replaced event builder, online computer farm and the storage system. The event builder and online computer farm are unified into one system. This event building farm uses commodity hardware and newly appended level 2 trigger functionality. This data acquisition system started its operation since last autumn and is very stable. We took 36 fb sup - sup 1 with new DAQ system, it had already overtaken 30 fb sup - sup 1 that is total amount of previous DAQ system.

    We review recent results on charmonium-like exotic states from the Belle experiment. The two-photon process $\\gamma \\gamma \\to \\phi \\jpsi$ is measured to search for Y(4140). No signal for the $Y(4140) \\to \\phi \\jpsi$ is observed. But a narrow peak with a significance of 3.2$\\sigma$ deviations including systematic uncertainty is observed at 4350.6 MeV/$c^2$ that we named X(4350). We also search for charmonium-like states, including X(3872), Y(4140), X(3915) and X(4350), in $\\Upsilon(1S)$ and $\\Upsilon(2S)$ radiative decays. No significant signal of any charmonium-like state is observed. The processes $\\gamma \\gamma \\to VV$ ($V=\\omega$ or $\\phi$) are also measured to search for the possible exotic states in low mass region. There are clear resonant structures in all the decay modes.

We discuss $CP$ asymmetries from the decay $B^{0} \\rightarrow \\pi^{+} \\pi^{-}$ and briefly mention a preliminary measurement of the branching fraction of $B\\to\\pi^0\\pi^0$ decays. Furthermore the measurement of the branching fraction of $B^{0}\\rightarrow \\rho^0\\rho^0$ decays and fraction of longitudinal polarization in this decay is presented. We use the results to constrain $\\phi_2$ with isospin analyses in the $B\\rightarrow \\pi\\pi$ and $B\\rightarrow\\rho\\rho$ systems.

  3. Performing CPR on a commercial diver inside the diving bell.

    2015-01-01

    CPR in a diving bell is difficult. It is taught by diving companies and training institutes but has not been subjected to the tenets of evidence based medicine. The diving bell lacks space as well as a flat hard surface to lay the patient on and therefore conventional methods of administering CPR are not possible. The diver is hung from a pulley tied to the diver's harness, and the bell flooded with water to reduce pooling of blood. Airway is established using a cervical collar to hyperextend the neck and inserting an appropriate oropharyngeal airway. Cardiac compressions are administered by the bellman using his head or the knee while holding the patient with his arms from behind. The bell can be recovered to surface only when spontaneous breathing and circulation have started. Diving bell offers a unique environment for management of unconscious casualties. Even though the method is at variance with the conventional method of administering CPR, it is the only method possible inside the bell. It is important that the method be scrutinized and refined so as to be more effective and efficacious inside the bell.

    We obtain a general connection between a large quantum advantage in communication complexity and Bell nonlocality. We show that given any protocol offering a sufficiently large quantum advantage in communication complexity, there exists a way of obtaining measurement statistics that violate some Bell inequality. Our main tool is port-based teleportation. If the gap between quantum and classical communication complexity can grow arbitrarily large, the ratio of the quantum value to the classical value of the Bell quantity becomes unbounded with the increase in the number of inputs and outputs.

    Full Text Available Through the analytical approach of studying official and perception-related discourse on bell ringing I accentuate the complexity of aspects that the sound of church bell presents in contemporary society. I point out the misleading officially defined level of noise nuisance and reveal how, when and why bell ringing is perceived as a positive or negative part of the acoustic environment. The study argues for a holistic approach to the noise nuisance issues, still much underestimated in the official discourse, that co-create our everyday soundscape.

  6. From Bell's inequalities to quantum information: a new quantum revolution

    In 1964, John Stuart Bell discovered that it is possible to settle the debate experimentally, by testing the famous "Bell's inequalities", and to show directly that the revolutionary concept of entanglement is indeed a reality. 

A long series of experiments closer and closer to the ideal scheme presented by Bell has confirmed that entanglement is indeed "a great quantum mystery", to use the words of Feynman. Based on that concept, a new field of research has emerged, quantum information, where one uses quantum bits, the so-called “qubits”, to encode the information and process it. Entanglement ...

    A next generation B-factory experiment, Belle II, is now being constructed at KEK in Japan. The upgraded accelerator SuperKEKB is designed to have the maximum luminosity of 8 × 1035 cm-2s-1 that is a factor 40 higher than the current world record. As a consequence, the Belle II detector yields a data stream of the event size ~1 MB at a Level 1 rate of 30 kHz. The Belle II High Level Trigger (HLT) is designed to reduce the Level 1 rate to 1/5 by performing the real time full event reconstruction and by applying the physics level event selection as the software trigger. In this paper, the development of the high level trigger system for Belle II and its performance is discussed.

    Full Text Available The novel begins as follows:"Dora Greenfield left her husband because she was afraid of him. She decided six months later to return to him for the same reason. The absent Paul, haunting her with letters and telephone bells and imagined footsteps on the stairs had begun to be the greater torment. Dora suffered from guilt, and with guilt came fear. She decided at last that the persecution of his presence was to be preferred to the persecution of his absence."Murdoch's novel The Bell is about Imber Court. It is a small Anglican religious community of lay people whose lives were transformed, not just by the arrival of a couple of dissimilar visitors, not just by the arrival of a new bell to be installed at Imber Abbey located beyond the lake, but more significantly by the discovery of a centuries-old bell the story of which is engulfed in a terrible legend.

    Inflammation and oedema of the facial nerve are implicated in causing Bell's palsy. Corticosteroids have a potent anti-inflammatory action that should minimise nerve damage. This is an update of a review first published in 2002 and last updated in 2010. To determine the effectiveness and safety of corticosteroid therapy in people with Bell's palsy. On 4 March 2016, we searched the Cochrane Neuromuscular Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and LILACS. We reviewed the bibliographies of the randomised trials and contacted known experts in the field to identify additional published or unpublished trials. We also searched clinical trials registries for ongoing trials. Randomised trials and quasi-randomised trials comparing different routes of administration and dosage schemes of corticosteroid or adrenocorticotrophic hormone therapy versus a control group receiving no therapy considered effective for this condition, unless the same therapy was given in a similar way to the experimental group. We used standard Cochrane methodology. The main outcome of interest was incomplete recovery of facial motor function (i.e. residual facial weakness). Secondary outcomes were cosmetically disabling persistent sequelae, development of motor synkinesis or autonomic dysfunction (i.e. hemifacial spasm, crocodile tears) and adverse effects of corticosteroid therapy manifested during follow-up. We identified seven trials, with 895 evaluable participants for this review. All provided data suitable for the primary outcome meta-analysis. One of the trials was new since the last version of this Cochrane systematic review. Risk of bias in the older, smaller studies included some unclear- or high-risk assessments, whereas we deemed the larger studies at low risk of bias. Overall, 79/452 (17%) participants allocated to corticosteroids had incomplete recovery of facial motor function six months or more after randomisation

  16. Characterization of the Bell-Shaped Vibratory Angular Rate Gyro

    Directory of Open Access Journals (Sweden)

    Junfang Fan

    2013-08-01

    Full Text Available The bell-shaped vibratory angular rate gyro (abbreviated as BVG is a novel shell vibratory gyroscope, which is inspired by the Chinese traditional bell. It sensitizes angular velocity through the standing wave precession effect. The bell-shaped resonator is a core component of the BVG and looks like the millimeter-grade Chinese traditional bell, such as QianLong Bell and Yongle Bell. It is made of Ni43CrTi, which is a constant modulus alloy. The exciting element, control element and detection element are uniformly distributed and attached to the resonator, respectively. This work presents the design, analysis and experimentation on the BVG. It is most important to analyze the vibratory character of the bell-shaped resonator. The strain equation, internal force and the resonator's equilibrium differential equation are derived in the orthogonal curvilinear coordinate system. When the input angular velocity is existent on the sensitive axis, an analysis of the vibratory character is performed using the theory of thin shells. On this basis, the mode shape function and the simplified second order normal vibration mode dynamical equation are obtained. The coriolis coupling relationship about the primary mode and secondary mode is established. The methods of the signal processing and control loop are presented. Analyzing the impact resistance property of the bell-shaped resonator, which is compared with other shell resonators using the Finite Element Method, demonstrates that BVG has the advantage of a better impact resistance property. A reasonable means of installation and a prototypal gyro are designed. The gyroscopic effect of the BVG is characterized through experiments. Experimental results show that the BVG has not only the advantages of low cost, low power, long work life, high sensitivity, and so on, but, also, of a simple structure and a better impact resistance property for low and medium angular velocity measurements.

    Full Text Available A phase doppler anemometer (PDA was used to determine the effects of evaporation on water spray for three rotary bell atomizer operational variable parameters: shaping air, bell speed and liquid flow. Shaping air was set at either 200 standard liters per minute (L/min or 300 L/min, bell speed was set to 30, 40 or 50 thousand rotations per minute (krpm and water flow rate was varied between 100, 200 or 300 cubic centimeters per minute (cm3/min. The total evaporation between 22.5 and 37.5 cm from the atomizer (cm3/s was calculated for all the combinations of those variables. Evaporation rate increased with higher flow rate and bell speed but no statistically significant effects were obtained for variable shaping air on interactions between parameters.

    The Belle II Experiment at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan, will explore the asymmetry between matter and antimatter and search for new physics beyond the standard model. 172 double-sided silicon strip detectors are arranged cylindrically in four layers around the collision point to be part of a system which measures the tracks of the collision products of electrons and positrons. A total of 1748 radiation-hard APV25 chips read out 128 silicon strips each and send the analog signals by time-division multiplexing out of the radiation zone to 48 Flash Analog Digital Converter Modules (FADC). Each of them applies processing to the data; for example, it uses a digital finite impulse response filter to compensate line signal distortions, and it extracts the peak timing and amplitude from a set of several data points for each hit, using a neural network. We present an overview of the SVD data readout system, along with front-end electronics, cabling, power supplies and data processing.

    By assuming a deterministic evolution of quantum systems and taking realism into account, we carefully build a hidden variable theory for Quantum Mechanics (QM) based on the notion of ontological states proposed by 't Hooft (The cellular automaton interpretation of quantum mechanics, arXiv:1405.1548v3, 2015; Springer Open 185, https://doi.org/10.1007/978-3-319-41285-6, 2016). We view these ontological states as the ones embedded with realism and compare them to the (usual) quantum states that represent superpositions, viewing the latter as mere information of the system they describe. Such a deterministic model puts forward conditions for the applicability of Bell's inequality: the usual inequality cannot be applied to the usual experiments. We build a Bell-like inequality that can be applied to the EPR scenario and show that this inequality is always satisfied by QM. In this way we show that QM can indeed have a local interpretation, and thus meet with the causal structure imposed by the Theory of Special Relativity in a satisfying way.

  2. ‘Speaking Kleinian’: Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis

    How did the complex concepts of psychoanalysis become popular in early twentieth-century Britain? This article examines the contribution of educator and psychoanalyst Susan Isaacs (1885–1948) to this process, as well as her role as a female expert in the intellectual and medical history of this period. Isaacs was one of the most influential British psychologists of the inter-war era, yet historical research on her work is still limited. The article focuses on her writing as ‘Ursula Wise’, answering the questions of parents and nursery nurses in the popular journal Nursery World, from 1929 to 1936. Researched in depth for the first time, Isaacs’ important magazine columns reveal that her writing was instrumental in disseminating the work of psychoanalyst Melanie Klein in Britain. Moreover, Isaacs’ powerful rebuttals to behaviourist, disciplinarian parenting methods helped shift the focus of caregivers to the child’s perspective, encouraging them to acknowledge children as independent subjects and future democratic citizens. Like other early psychoanalysts, Isaacs was not an elitist; she was in fact committed to disseminating her ideas as broadly as possible. Isaacs taught British parents and child caregivers to ‘speak Kleinian’, translating Klein’s intellectual ideas into ordinary language and thus enabling their swift integration into popular discourse.

    How can managers increase the productivity of professionals when most of their work goes on inside their heads? Robert Kelley and Janet Caplan believe that defining the difference between star performers and average workers is the answer. Many managers assume that top performers are just smarter. But the authors' research at the Bell Laboratories Switching Systems Business Unit (SSBU) has revealed that the real difference between stars and average workers is not IQ but the ways top performers do their jobs. Their study has led to a training program based on the strategies of star performers. The SSBU training program, known as the Productivity Enhancement Group (PEG), uses an expert model to demystify productivity. The star engineers selected to develop the expert model identified and ranked nine work strategies, such as taking initiative, networking, and self-management. Middle performers were also asked what makes for top-quality work, but their definitions and ranking of the strategies differed significantly from those of the top performers. Taking initiative, for example, meant something very different to an average worker than it did to a star. And for the middle performers, the ability to give good presentations was a core strategy, while it was peripheral for the top engineers. Once PEG got underway, respected engineers ran the training sessions, which included case studies, work-related exercises, and frank discussion. The benefits of the program were striking: participants and managers reported substantial productivity increases in both star and average performers. The PEG program may not be a blueprint for other companies, but its message is clear: managers must focus on people, not on technology, to increase productivity in the knowledge economy.

  4. The Belle II DEPFET pixel detector

    2016-09-01

    The Belle II experiment at KEK (Tsukuba, Japan) will explore heavy flavour physics (B, charm and tau) at the starting of 2018 with unprecedented precision. Charged particles are tracked by a two-layer DEPFET pixel device (PXD), a four-layer silicon strip detector (SVD) and the central drift chamber (CDC). The PXD will consist of two layers at radii of 14 mm and 22 mm with 8 and 12 ladders, respectively. The pixel sizes will vary, between 50 μm×(55-60) μm in the first layer and between 50 μm×(70-85) μm in the second layer, to optimize the charge sharing efficiency. These innermost layers have to cope with high background occupancy, high radiation and must have minimal material to reduce multiple scattering. These challenges are met using the DEPFET technology. Each pixel is a FET integrated on a fully depleted silicon bulk. The signal charge collected in the 'internal gate' modulates the FET current resulting in a first stage amplification and therefore very low noise. This allows very thin sensors (75 μm) reducing the overall material budget of the detector (0.21% X0). Four fold multiplexing of the column parallel readout allows read out a full frame of the pixel matrix in only 20 μs while keeping the power consumption low enough for air cooling. Only the active electronics outside the detector acceptance has to be cooled actively with a two phase CO2 system. Furthermore the DEPFET technology offers the unique feature of an electronic shutter which allows the detector to operate efficiently in the continuous injection mode of superKEKB.

    SuperKEKB, the next generation B factory, has been constructed in Japan as an upgrade of KEKB. This brand new e+ e- collider is expected to deliver a very large data set for the Belle II experiment, which will be 50 times larger than the previous Belle sample. Both the triggered physics event rate and the background event rate will be increased by at least 10 times than the previous ones, and will create a challenging data taking environment for the Belle II detector. The software system of the Belle II experiment is designed to execute this ambitious plan. A full detector simulation library, which is a part of the Belle II software system, is created based on Geant4 and has been tested thoroughly. Recently the library has been upgraded with Geant4 version 10.1. The library is behaving as expected and it is utilized actively in producing Monte Carlo data sets for various studies. In this paper, we will explain the structure of the simulation library and the various interfaces to other packages including geometry and beam background simulation.

  6. Chemical reactions modulated by mechanical stress: extended Bell theory.

    A number of recent studies have shown that mechanical stress can significantly lower or raise the activation barrier of a chemical reaction. Within a common approximation due to Bell [Science 200, 618 (1978)], this barrier is linearly dependent on the applied force. A simple extension of Bell's theory that includes higher order corrections in the force predicts that the force-induced change in the activation energy will be given by -FΔR - ΔχF(2)∕2. Here, ΔR is the change of the distance between the atoms, at which the force F is applied, from the reactant to the transition state, and Δχ is the corresponding change in the mechanical compliance of the molecule. Application of this formula to the electrocyclic ring-opening of cis and trans 1,2-dimethylbenzocyclobutene shows that this extension of Bell's theory essentially recovers the force dependence of the barrier, while the original Bell formula exhibits significant errors. Because the extended Bell theory avoids explicit inclusion of the mechanical stress or strain in electronic structure calculations, it allows a computationally efficient characterization of the effect of mechanical forces on chemical processes. That is, the mechanical susceptibility of any reaction pathway is described in terms of two parameters, ΔR and Δχ, both readily computable at zero force.

  7. (Nearly) optimal P values for all Bell inequalities

    2016-10-01

    A key objective in conducting a Bell test is to quantify the statistical evidence against a local-hidden variable model (LHVM) given that we can collect only a finite number of trials in any experiment. The notion of statistical evidence is thereby formulated in the framework of hypothesis testing, where the null hypothesis is that the experiment can be described by an LHVM. The statistical confidence with which the null hypothesis of an LHVM is rejected is quantified by the so-called P value, where a smaller P value implies higher confidence. Establishing good statistical evidence is especially challenging if the number of trials is small, or the Bell violation very low. Here, we derive the optimal P value for a large class of Bell inequalities. What is more, we obtain very sharp upper bounds on the P value for all Bell inequalities. These values are easily computed from the experimental data, and are valid even if we allow arbitrary memory in the devices. Our analysis is able to deal with imperfect random number generators, and event-ready schemes, even if such a scheme can create different kinds of entangled states. Finally, we review requirements for sound data collection, and a method for combining P values of independent experiments. The methods discussed here are not specific to Bell inequalities. For instance, they can also be applied to the study of certified randomness or to tests of noncontextuality.

    2006-01-01

    The aim of this study was to evaluate a physiotherapeutic treatment intervention in Bell's palsy. A consecutive series of nine patients with Bell's palsy participated in the study. The subjects were enrolled 4-21 weeks after the onset of facial paralysis. The study had a single subject experimental design with a baseline period of 2-6 weeks and a treatment period of 26-42 weeks. The patients were evaluated using a facial grading score, a paresis index and a written questionnaire created for this study. Every patient was taught to perform an exercise program twice daily, including movements of the muscles surrounding the mouth, nose, eyes and forehead. All the patients improved in terms of symmetry at rest, movement and function. In conclusion, patients with remaining symptoms of Bell's palsy appear to experience positive effects from a specific training program. A larger study, however, is needed to fully evaluate the treatment.

  10. Feasible logic Bell-state analysis with linear optics.

    2016-02-15

    We describe a feasible logic Bell-state analysis protocol by employing the logic entanglement to be the robust concatenated Greenberger-Horne-Zeilinger (C-GHZ) state. This protocol only uses polarization beam splitters and half-wave plates, which are available in current experimental technology. We can conveniently identify two of the logic Bell states. This protocol can be easily generalized to the arbitrary C-GHZ state analysis. We can also distinguish two N-logic-qubit C-GHZ states. As the previous theory and experiment both showed that the C-GHZ state has the robustness feature, this logic Bell-state analysis and C-GHZ state analysis may be essential for linear-optical quantum computation protocols whose building blocks are logic-qubit entangled state.

    Full Text Available Abstract Background This study aimed to evaluate the still unknown factors correlating with the degree of nerve involvement in early Bell's palsy. Methods This retrospective chart review study of newly diagnosed cases of Bell's palsy was conducted over a three-year period. Information on age, sex, day of onset, comorbidities, corticosteroid use, and electroneurographic test results were collected. The electroneurographic quotient (amplitude of compound muscle action potential on the affected side divided by that on the healthy side and expressed in percent was used as an index of nerve involvement, with lower quotient indicating more severe disease. Results Data were collected on 563 patients. The mean electroneurographic quotient varied inversely with age (p vs. 40.3%; p = 0.002. There was no correlation between the degree of nerve involvement and sex, season of onset, hypertension, or diabetes. Conclusion The degree of nerve involvement in early Bell's palsy correlates positively with age and negatively with corticosteroid use.

    Classical public key cryptosystems ( P K C), such as R S A, E I G a m a l, E C C, are no longer secure in quantum algorithms, and quantum cryptography has become a novel research topic. In this paper we present a quantum asymmetrical cryptosystem i.e. quantum public key cryptosystem ( Q P K C) based on the Bell states. In particular, in the proposed QPKC the public key are given by the first n particles of Bell states and generalized Pauli operations. The corresponding secret key are the last n particles of Bell states and the inverse of generalized Pauli operations. The proposed QPKC encrypts the message using a public key and decrypts the ciphertext using a private key. By H o l e v o ' s theorem, we proved the security of the secret key and messages during the QPKC.

    John Bell, brother-surgeon of Charles Bell, was, like Charles, an outstanding surgeon and a good artist. John was one of the few who illustrated his work with their own drawings in the days before audiovisual aids were available and without the benefit of reliable drawing aids, photography and computer-aided design. Charles, on the other hand, was the better artist and illustrated much of the normal anatomy of the nervous system. Each brother undertook extensive surgery of men who had been wounded in war; John Bell left us his engravings from the textbooks, more numerous perhaps than Charles, but Charles left us a series of oil paintings and watercolours in addition to the illustrations in his textbooks. © 2013 Elsevier B.V.

    We report on the experimental violation of multipartite Bell inequalities by entangled states of trapped ions. First, we consider resource states for measurement-based quantum computation of between 3 and 7 ions and show that all strongly violate a Bell-type inequality for graph states, where the criterion for violation is a sufficiently high fidelity. Second, we analyze Greenberger-Horne-Zeilinger states of up to 14 ions generated in a previous experiment using stronger Mermin-Klyshko inequalities, and show that in this case the violation of local realism increases exponentially with system size. These experiments represent a violation of multipartite Bell-type inequalities of deterministically prepared entangled states. In addition, the detection loophole is closed.

    In recent decades, a great variety of research and applications concerning Bell nonlocality have been developed with the advent of quantum information science. Providing that Bell nonlocality can be revealed by the violation of a family of Bell inequalities, finding maximal Bell violation (MBV) for unknown quantum states becomes an important and inevitable task during Bell experiments. In this paper we introduce a self-guided method to find MBVs for unknown states using a stochastic gradient ascent algorithm (SGA), by parametrizing the corresponding Bell operators. For three investigated systems (two qubit, three qubit, and two qutrit), this method can ascertain the MBV of general two-setting inequalities within 100 iterations. Furthermore, we prove SGA is also feasible when facing more complex Bell scenarios, e.g., d -setting d -outcome Bell inequality. Moreover, compared to other possible methods, SGA exhibits significant superiority in efficiency, robustness, and versatility.

    Over the last 80 years, Bell Labs has been one of the most scientifically and technologically productive research labs in the world. Inventions such as the transistor, laser, cell phone, solar cell, negative feedback amplifier, communications satellite and many others were made there. Scientific breakthroughs such as discovery of the Big Bang, the wave nature of the electron, electron localization and the fractional quantum hall effect were also made there making Bell Labs almost unique in terms of large impacts in both science and technology. In my talk, I will discuss the history of the lab, talk about the present and give some suggestions for how I see it evolving into the future.

  18. Diasporic Reconciliations of Politics, Love and Trauma: Susan Abulhawa’s Quest for Identity in Mornings in Jenin

    2015-04-01

    Full Text Available Negotiating human conditions is an emblematic critical impetus of diaspora informed by multiple cultural possibilities practiced through the creation of multiple spaces that cross the realm of the ‘self’ to that of the ‘other’. It offers a locale to cross from the oppressed ‘self’ to an understanding of an oppressor ‘other’. Yet, diasporic negotiation is politically involved in the most responsible manner; it engages the contextual social realities in order to enable creative possibilities for overcoming the logic of the politics altogether. It invites a kind of political involvement that assures the ‘situatedness of the ethical’ in a framework of moral humanistic realisations. The realisation of diasporic negotiations is dialogically engaged in manners that will give birth to new possibilities for human togetherness. In this essay, I trace the signs of diasporic negotiations of politics, love and trauma in Susan Abulhawa’s Mornings in Jenin by focusing on the Diasporic identity of Amal (the central character. I consider the intersections between diaspora, dislocation of identity and the creation of negotiating spaces that qualify an 'epistemology of Diaspora' against essentialised and ethnocentric construction of realities. I argue that Abulhawa creates diasporic spaces and immense moral scenes to transcend a particular stance of politics via transcending love in opposition to suffering and tribulation. I contend that Abulhawa’s conceptualisation of Diasporic negotiations enables her to depict and gauge two extreme human sentiments: love and trauma, yet, without yielding or compromising the right of just resistance and dissent.

    An initial evaluation is made of extensive three-component (3C) particle image velocimetry (PIV) measurements within the wake across a rotor disk plane. The model is a 40 percent scale BO-105 helicopter main rotor in forward flight simulation. This study is part of the HART II test program conducted in the German-Dutch Wind Tunnel (DNW). Included are wake vortex field measurements over the advancing and retreating sides of the rotor operating at a typical descent landing condition important for impulsive blade-vortex interaction (BVI) noise. Also included are advancing side results for rotor angle variations from climb to steep descent. Using detailed PIV vector maps of the vortex fields, methods of extracting key vortex parameters are examined and a new method was developed and evaluated. An objective processing method, involving a center-of-vorticity criterion and a vorticity 'disk' integration, was used to determine vortex core size, strength, core velocity distribution characteristics, and unsteadiness. These parameters are mapped over the rotor disk and offer unique physical insight for these parameters of importance for rotor noise and vibration prediction.

    Assimilation by mafic to ultramafic magmas of sulfur-bearing country rocks is considered an important contributing factor to reach sulfide saturation and form magmatic Ni-Cu-platinum group element (PGE) sulfide deposits. Sulfur-bearing sedimentary rocks in the Archean are generally characterized by mass-independent fractionation of sulfur isotopes that is a result of atmospheric photochemical reactions, which produces isotopically distinct pools of sulfur. Likewise, low-temperature processing of iron, through biological and abiotic redox cycling, produces a range of Fe isotope values in Archean sedimentary rocks that is distinct from the range of the mantle and magmatic Fe isotope values. Both of these signals can be used to identify potential country rock assimilants and their contribution to magmatic sulfide deposits. We use multiple S and Fe isotopes to characterize the composition of the potential iron and sulfur sources for the sulfide liquids that formed the Hart deposit in the Shaw Dome area within the Abitibi greenstone belt in Ontario (Canada). The Hart deposit is composed of two zones with komatiite-associated Ni-Cu-PGE mineralization; the main zone consists of a massive sulfide deposit at the base of the basal flow in the komatiite sequence, whereas the eastern extension consists of a semi-massive sulfide zone located 12 to 25 m above the base of the second flow in the komatiite sequence. Low δ56Fe values and non-zero δ34S and Δ33S values of the komatiitic rocks and associated mineralization at the Hart deposit is best explained by mixing and isotope exchange with crustal materials, such as exhalite and graphitic argillite, rather than intrinsic fractionation within the komatiite. This approach allows tracing the extent of crustal contamination away from the deposit and the degree of mixing between the sulfide and komatiite melts. The exhalite and graphitic argillite were the dominant contaminants for the main zone of mineralization and the eastern

    2014-11-01

    Jellyfish represent one of the earliest and simplest examples of swimming by a macroscopic organism. Contractions of an elastic bell that expels water are driven by coronal swimming muscles. The re-expansion of the bell is passively driven by stored elastic energy. A current question in jellyfish propulsion is how the underlying neuromuscular organization of their bell allows for maneuvering. Using an immersed boundary framework, we will examine the mechanics of swimming by incorporating material models that are informed by the musculature present in jellyfish into a model of the elastic jellyfish bell in three dimensions. The fully-coupled fluid structure interaction problem is solved using an adaptive and parallelized version of the immersed boundary method (IBAMR). We then use this model to understand how variability in the muscular activation patterns allows for complicated swimming behavior, such as steering. We will compare the results of the simulations with the actual turning maneuvers of several species of jellyfish. Numerical flow fields will also be compared to those produced by actual jellyfish using particle image velocimetry (PIV).

  5. Recent approaches for bell pepper seed vigor testing

    Marcos Altomani Neves Dias

    2014-08-01

    Full Text Available Seed vigor is a major attribute in the determination of whether a seed lot can be commercialized. Different physiological tests are used to assess seed vigor and are generally based on different concepts, which could lead to variable interpretations, particularly when comparing lots presenting different vigor levels. This study was conducted to compare the different approaches used to evaluate bell pepper seed vigor and verify the applicability of the Seed Vigor Imaging System (SVIS for this purpose. The experiment was performed using four seed lots of bell pepper hybrids in two periods, and the evaluations involved germination, seedling emergence, seedling emergence speed index, saturated salt accelerated aging and image analysis. The use of seedling imaging analysis by SVISis a new approach for bell pepper seed vigor evaluation. Both the software and traditional tests provided sufficient information for seed vigor analysis, enabling the segregation of the analyzed seed lots. Thus, the new method fulfills the requirement for an efficient, rapid, cost-effective and standardized method that allows comparisons among laboratories and avoids human influence on the interpretation of the results. SVIS can be considered a feasible option to be included in quality assurance programs of the bell pepper seed industry.

    Full Text Available This report was done to observe the effect of Hominis placenta herbal acupuncture on Bell's palsy. The study group comprised 16 patients who arrived at Woo-suk university oriental hospital from January, 1999 till January, 2000 for Bell's palsy. All patients were divided into two group. One was herbal acupunture group, and the other was control group. Acupunture group was done herbal acupuncture therapy on the facial acupuncture points. Followings are achievement and a term of each group. In herbal acupuncture group, 100% motor recovery was 7 case, 75% was 1 case, and 25% motor recovery term was 7.38±5.21 days, 50% was 11.00±6.16 days, 75% was 15.13±9.55 days, 100% was 23.14±7.97 days. In control group, 100% motor recovery was 4 case, 75% was 2 case, 25% below was 2 case and 25% motor recovery term was 11.17±4.96days, 50% was 18.17±6.82 days, 75% was 29.50±6.95 days, 100% was 44.00±11.49 days. The above results indicate that Hominis placenta herbal acupuncture is a useful effect on Bell's palsy. thus, continuous herbal acupunture study will be needed for more clinical application on Bell' palsy.

    2016-01-01

    Conclusions Defectively healed facial paralysis causes difficulties to talk and eat, involuntary spasms (synkinesis), and cosmetic deformities which can give rise both to severe psychological and physical trauma. A team consisting of Ear-Nose-Throat specialists, Plastic surgeons and Physiotherapists can offer better care, treatment and outcome for patients suffering from Bells' palsy. Objectives Patients suffering from Bells' palsy from all ENT hospitals in Sweden and the University Hospital in Helsinki has been included. Methods Results have been drawn and statistically processed for different outcomes from a prospective, double blind cross over study. Results from a pilot surgical study and therapeutic results from physiotherapy studies have been included. Ideas concerning different kinds of surgery will be reviewed and the role of physiotherapy discussed. Results According to common results, treatment with Prednisolone enhances the recovery rate and should, if possible, be used early in the course. Sunnybrook grading at 1 month after onset most accurately predicts non-recovery at 12 months in Bells' palsy and a risk factor curve will be presented in order to predict outcome and selection of patients for undergoing facial surgery. This report is focusing on how to handle patients with Bells' palsy from a multi-rehabilitation team point of view, and what will be recommended to provide these patients with the best clinical and surgical help.

    Full Text Available Bell's Palsy is a peripheral facial nerve weakness (facial nerve with acute onset on one side of the face. This condition causes the inability of the patient to move half of his face consciously (volunter on the affected side. The Bell's Palsy incidence is 20-30 cases out of 100.000 people and accounts for 60-70% of all cases of unilateral facial paralysis. The disease is self-limited, but causes great suffering for patients who are not treated properly. Controversy in the management is still debated, and the cause is still unknown. The underlying hypothesis is ischemic, vascular, viral, bacterial, hereditary, and immunologic. Therapy done so far is to improve facial nerve function and healing process. The management of the therapy used will be closely related to the structure of the anatomy and its functions and associated abnormalities. The modalities of Bell's Palsy therapy are with corticosteroids and antivirals, facial exercises, electrostimulation, physiotherapy and decompression operations. Approximately 80-90% of patients with Bell's palsy recover completely within 6 months, even in 50-60% of cases improved within 3 weeks. Approximately 10% experienced persistent facial muscle asymmetry, and 5% experienced severe sequelae, and 8% of cases were recurrent.

    The BIG Bell test uses the input from the Bellsters, self-selected human participants introducing zeros and ones through an online videogame, to perform a suite of quantum physics experiments. In this talk, we will explore the videogame, the data infrastructure and the outreach efforts of the BIG Bell test collaboration. First, we will discuss how the game was designed so as to eliminate possible feedback mechanisms that could influence people's behavior. Second, we will discuss the cloud architecture design for scalability as well as explain how we sent each individual bit from the users to the labs. Also, and using all the bits collected via the BIG Bell test interface, we will show a data analysis on human randomness, e.g. are younger Bellsters more random than older Bellsters? Finally, we will talk about the outreach and communication efforts of the BIG Bell test collaboration, exploring both the social media campaigns as well as the close interaction with teachers and educators to bring the project into classrooms.

  20. History of Belle and some of its lesser known highlights

    CERN Document Server

    Olsen, Stephen Lars

    2016-01-01

    I report on the early history of Belle, which was almost entirely focused on testing the Kobayashi Maskawa mechanism for $CP$ violation that predicted large matter-antimatter asymmetries in certain $B$ meson decay modes. Results reported by both BaBar and Belle in the summer of 2001 verified the Kobayashi Maskawa idea and led to their Nobel prizes in 2008. In addition to studies of CP violation, Belle (and BaBar) reported a large number of important results on a wide variety of other subjects, many of which that had nothing to do with B mesons. In this talk I cover three (of many) subjects where Belle measurements have had a significant impact on specific sub-fields of hadron physics but are not generally well know. These include: the discovery of an anomalously large cross sections for double charmonium production in continuum e+e- annihilation; sensitive probes of the structure of the low-mass scalar mesons; and first measurements of the Collins spin fragmentation function.

  4. Analysis of just Noticeable Difference in Spectrum of Church Bell Sound

    Directory of Open Access Journals (Sweden)

    A. Samolov

    2010-11-01

    Full Text Available Bells are specific sound sources. They have distinct, but, unlike musical instruments, inharmonious partials. These partials arise from modes of vibration of the bell and depend on dimensions and potential irregularities of the bell. Therefore, the question of a just noticeable difference in the church bell sound is of great importance. Analysis of subjective tests with synthetic sounds of two bells, different in size, is described in this paper. We report results for a just noticeable difference of partial frequency in the range 10-15 cents. Frequency dependence, is also, noticed.

  5. Bell violation for the thermal states of an XXZ spin chain with Dzialoshiski-Moriya interaction

    2010-11-01

    The effect of Dzialoshiski-Moriya (DM) interaction on the violation of Bell inequality for thermal states of interacting qubits via a two-qubit XXZ spin chain is investigated. Our results imply that the DM interaction and anisotropy taking a large positive value can enhance the Bell violation and improve the threshold temperatures of it. By the comparison between the Bell violation and thermal entanglement, we find that the threshold temperatures of thermal entanglement are higher than those of the Bell violation. This implies that some states are entangled but the Bell inequality is not violated.

    Full Text Available This population-based cohort study investigated the risk of developing peripheral arterial occlusive disease (PAOD in patients with Bell's palsy.We used longitudinal claims data of health insurance of Taiwan to identify 5,152 patients with Bell's palsy newly diagnosed in 2000-2010 and a control cohort of 20,608 patients without Bell's palsy matched by propensity score. Incidence and hazard ratio (HR of PAOD were assessed by the end of 2013.The incidence of PAOD was approximately 1.5 times greater in the Bell's palsy group than in the non-Bell's palsy controls (7.75 vs. 4.99 per 1000 person-years. The Cox proportional hazards regression analysis measured adjusted HR was 1.54 (95% confidence interval (CI = 1.35-1.76 for the Bell's palsy group compared to the non-Bell's palsy group, after adjusting for sex, age, occupation, income and comorbidities. Men were at higher risk of PAOD than women in the Bell's palsy group, but not in the controls. The incidence of PAOD increased with age in both groups, but the Bell's palsy group to control group HR of PAOD decreased as age increased. The systemic steroid treatment reduced 13% of PAOD hazard for Bell's palsy patients, compared to those without the treatment, but not significant.Bell's palsy appears to be associated with an increased risk of developing PAOD. Further pathophysiologic, histopathology and immunologic research is required to explore the underlying biologic mechanism.

    The Reverend William Bell had six children who survived infancy. Two of his sons entered the legal profession and two other sons became distinguished anatomists and surgeons--John Bell, said for 20 years to have been the leading operating surgeon in Britain and throughout the world--and Sir Charles Bell, possibly the most distinguished anatomist and physiologist of his day. Information is not known about the fifth son or their sister. Charles Shaw, a lawyer of Ayr, had four sons and two daughters who survived infancy. Two of his sons, John and Alexander, became anatomists and later surgeons at the Middlesex Hospital, and both worked closely with Charles Bell at the Great Windmill Street School of Anatomy. His third son entered the law and his fourth son became a distinguished soldier. The two daughters of Charles Shaw married into the Bell family: Barbara married George Joseph Bell and Marion married Mr (later Sir) Charles Bell.

    This is author-approved bcc. If it is too long, delete the last sentence in each of the biographies. THE BELL CURVE by Richard Herrnstein and Charles Murray, a best selling book published in 1994, set off a hailstorm of controversy about the relationships among IQ, genetics, and various social outcomes, including welfare dependency, crime, and earnings. Much of the public reaction to the book was polemical and did not focus on the details of the science and in particular on the validity of the statistical arguments that underlie the books's conclusions. A detailed understanding of the arguments in THE BELL CURVE requires knowledge about (i) statistical models for genetic heritability, (ii) factor analysis, especially as it has been applied to the analysis of IQ tests, (iii) logistic regression and multiple regression analyses,and (iv) causal modelling and alternative statistical frameworks for making inference from longitudinal data.

    Corticosteroids are widely used in the treatment of idiopathic facial paralysis (Bell's palsy), but the effectiveness of additional treatment with an antiviral agent is uncertain. Significant morbidity can be associated with severe cases of Bell's palsy. To assess the effects of antiviral treatments alone or in combination with any other therapy for Bell's palsy. On 7 October 2014 we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE, EMBASE, LILACS, DARE, NHS EED, and HTA. We also reviewed the bibliographies of the identified trials and contacted trial authors and known experts in the field and relevant drug companies to identify additional published or unpublished data. We searched clinical trials registries for ongoing studies. We considered randomised controlled trials or quasi-randomised controlled trials of antivirals with and without corticosteroids versus control therapies for the treatment of Bell's palsy. We excluded trials that had a high risk of bias in several domains. Pairs of authors independently assessed trials for relevance, eligibility, and risk of bias, using standard Cochrane procedures. Eleven trials, including 2883 participants, met the inclusion criteria and are included in the final analysis. We added four studies to the previous review for this update. Some of the trials were small, and a number were at high or unclear risk of bias. Other trials did not meet current best standards in allocation concealment and blinding.

For people with severe Bell's palsy (House-Brackmann scores of 5 and 6 or the equivalent in other scales), we found a reduction in the rate of incomplete recovery at month six when antivirals plus corticosteroids were used (RR 0.64, 95% CI 0.41 to 0

    We report correlation measurements on two 9Be+ ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled as derived from a mixture of a local-realistic probabilistic distribution and a distribution that violates the inequality. A statistical framework is formulated to quantify the local-realistic fraction allowable in the observed distribution without the fair-sampling or independent-and-identical-distributions assumptions. We exclude models of our experiment whose local-realistic fraction is above 0.327 at the 95% confidence level. This bound is significantly lower than 0.586, the minimum fraction derived from a perfect Clauser-Horne-Shimony-Holt inequality experiment. Furthermore, our data provide a device-independent certification of the deterministically created Bell states.

    Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of ...

    Hormesis, or biological effects of low level exposures (BELLE), is characterized by nonmonotonic dose response which is biphasic, displaying opposite effects at low and high dose. Its occurrence has been documented across a broad range of biological models and diverse type of exposure. Since hormesis appears to be a relatively common phenomenon in many areas, the objective of this review is to explore its occurrence related to dermatology and its public health and risk assessment implication....

    The principal goal of the B-factories is to test the CKM paradigm through measurements that overconstrain the shape of the so-called Unitarity Triangle. The sides of the triangle are evaluated through absolute values of several elements of the CKM matrix, so achieving high precision on these is an important aspect of the B-factory program. Recent results from Belle and Babar are presented.

    Based on the Bardeen Cooper Schrieffer (BCS) theory of superconductivity, the coherent splitting of Cooper pairs from a superconductor to two spatially separated quantum dots has been predicted to generate nonlocal pairs of entangled electrons. In order to test this hypothesis, we propose a scheme to transfer the spin state of a split Cooper pair onto the polarization state of a pair of optical photons. We show that the produced photon pairs can be used to violate a Bell inequality, unambiguo...

    This book expounds three special kinds of matrices that are of physical interest, centering on physical examples. Stochastic matrices describe dynamical systems of many different types, involving (or not) phenomena like transience, dissipation, ergodicity, nonequilibrium, and hypersensitivity to initial conditions. The main characteristic is growth by agglomeration, as in glass formation. Circulants are the building blocks of elementary Fourier analysis and provide a natural gateway to quantum mechanics and noncommutative geometry. Bell polynomials offer closed expressions for many formulas co

    The new Belle II experiment at the asymmetric e+e-accelerator SuperKEKB at KEK in Japan is designed to deliver a peak luminosity of 8 × 1035cm-2s-1. To perform high-precision track reconstruction, e.g. for measurements of time-dependent CP-violating decays and secondary vertices, the Belle II detector is equipped with a highly segmented pixel detector (PXD). The high instantaneous luminosity and short bunch crossing times result in a large stream of data in the PXD, which needs to be significantly reduced for offline storage. The data reduction is performed using an FPGA-based Data Acquisition Tracking and Concentrator Online Node (DATCON), which uses information from the Belle II silicon strip vertex detector (SVD) surrounding the PXD to carry out online track reconstruction, extrapolation to the PXD, and Region of Interest (ROI) determination on the PXD. The data stream is reduced by a factor of ten with an ROI finding efficiency of >90% for PXD hits inside the ROI down to 50MeV in pT of the stable particles. We will present the current status of the implementation of the track reconstruction using Hough transformations, and the results obtained for simulated ϒ(4S) → BB¯ events.

    Bell's palsy is defined as a peripheral facial nerve palsy, idiophatic, and sudden onset and is considered the most common cause of this pathology. It is caused by damage to cranial nerves VII, resulting in complete or partial paralysis of the facial mimic. May be associated with taste disturbances, salivation, tearing and hyperacusis. It is diagnosed after ruling out all possible etiologies, because its cause is not fully understood.Some researches shows that herpes virus may cause this type of palsy due to reactivation of the virus or by imunnomediated post-viral nerve demielinization. Physical therapy, corticosteroids and antiviral therapy have become the most widely accepted treatments for Bell's palsy. Therapy with low-level laser (LLLT) may induce the metabolism of injured nerve tissue for the production of proteins associated with its growth and to improve nerve regeneration. The success of the treatment of Bell's palsy by using laser phototherapy isolated or in association with other therapeutic approach has been reported on the literature. In most cases, the recovery occurs without uneventfully (complications), the acute illness is not associated with serious disorders. We will present a clinical approach for treating this condition.

    2015-09-17

    A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular rate output signal and bell-shaped resonator character, analyze the influence of the main error sources and set up an error model for the BVG. The error sources are classified from the error propagation characteristics, and the compensation method is presented based on the error model. Finally, using the error model and compensation method, the BVG is calibrated experimentally including rough compensation, temperature and bias compensation, scale factor compensation and noise filter. The experimentally obtained bias instability is from 20.5°/h to 4.7°/h, the random walk is from 2.8°/h(1/2) to 0.7°/h(1/2) and the nonlinearity is from 0.2% to 0.03%. Based on the error compensation, it is shown that there is a good linear relationship between the sensing signal and the angular velocity, suggesting that the BVG is a good candidate for the field of low and medium rotational speed measurement.

    In order to examine whether the characteristics of the bell are coincident with the design and make some constructive suggestions for the tuning of bell, the frequency characteristics of sound and the vibrational modes of a two-tone Chinese Peace Bell have been studied. With Welch's spectral estimate, the main partials of radiated sound of the bell have been found out. With time-frequency analysis, the changes of the spectrum with time have been shown. By conditional mean frequency (CMF) of the spectrogram of the sound, the change in the pitch of the bell has been discussed. With an accelerator, the vibration distributions on the different points of the bell have been measured. With short time spectrum analysis, the vibrational modes at different frequencies have been reconstructed.

    Oriental bells produce a peculiar sound in the form of beats, which are periodic repetitions of strong and weak sounds. A beating sound with a proper period gives the illusion of the bell being alive and breathing. To produce a good beating sound, appropriate modal parameters are required for beat tuning after casting the bell. Conventionally, modal parameters were extracted using frequency response functions of the excitation and response signals. However, a large oriental bell is usually struck by a heavy wooden hammer and hence, only the response signal can be measured. In this study, we extract the modal parameters using the response signal only and employ the data to predict the beat properties of the bell sound. Finally, the validity of the predicted beat properties is experimentally verified for a large oriental bell.

    The Belle II calorimeter (at least, its barrel part) consists of CsI(Tl) scintillation crystals which have been used at the Belle experiment. We perform the radiation hardness study of some typical Belle crystals and conclude their light output reductions are acceptable for Belle II experiment where the absorption dose can reach 10 krad during the detector operation. CsI(Tl) crystals have high stablity and low maintenance cost and are considered as possible option for the calorimeter of the future Super-Charm-Tau factory (SCT) in Novosibirsk. Our study demonstrates sufficiently high radiation hardness of CsI(Tl) crystals for SCT conditions.

    Bell's palsy (idiopathic facial paralysis) is commonly treated by physical therapy services with various therapeutic strategies and devices. There are many questions about their efficacy and effectiveness. To evaluate the efficacy of physical therapies on the outcome of Bell's palsy. We searched the Cochrane Neuromuscular Disease Group Trials Register (February 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2007), MEDLINE (January 1966 to February 2008), EMBASE (January 1980 to February 2008), LILACS (January 1982 to February 2008), PEDro (from 1929 to February 2008), and CINAHL (January 1982 to February 2008). We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. Titles and abstracts identified from the register were scrutinized. The assessment of methodological quality took into account secure method of randomisation, allocation concealment, observer blinding, patient blinding, differences at baseline of the experimental groups, and completeness of follow-up. Data were extracted using a specially constructed data extraction form. Separate subgroup analyses of participants with more and less severe disability were undertaken. The search identified 45 potentially relevant articles. Six studies met the inclusion criteria. Three trials studied the efficacy of electrostimulation (294 participants) and three exercises (253 participants). Neither treatment produced significantly more improvement than the control treatment or no treatment. There was limited evidence that improvement began earlier in the exercise group. There is no evidence of significant

    It is useful to perform neurophysiologic electromyography and electroneurography (EMG/ENG) on patients with peripheral facial palsy during the acute phase of paralysis in order to assess the severity of their nerve lesion and thus plan rehabilitation treatment and evaluate its results. To evaluate the motor recovery of patients with Bell's palsy with respect to the severity of their neurological lesion and to compare the results of two different rehabilitation treatments, with electromyographic biofeedback (EMG-BFB) and mirror visual biofeedback (mirror-BFB), in patients with Bell's palsy and neurophysiologic pattern of axonotmesis. Cohort study on retrospective clinical records. 102 patients with Bell's facial palsy were clinically assessed according to the House scale both during the acute phase of paralysis and 12 months after onset. All patients underwent EMG/ENG examination 3-4 weeks after the onset of paralysis; 29 patients had an EMG pattern of neurapraxia and were not given rehabilitation treatment; 73 patients who presented with signs of denervation had an EMG pattern of axonotmesis. The group, which was homogenous in terms of lesion severity, was divided into two parts: 38 patients were treated with electromyographic biofeedback (EMG-BFB) and 35 were treated with mirror visual feedback (mirror-BFB). All 29 patients with neurapraxia made a full spontaneous recovery; Although the 73 patients with axonotmesis received different types of rehabilitation treatment, they obtained similar results regarding quality of recovery, development of synkinesis, rehabilitation timing and resources used. Rehabilitation treatment is not necessary for patients with neurapraxia. The two biofeedback methods used to treat patients with axonotmesis resulted in similar rehabilitation outcomes.

    Corticosteroids are widely used in the treatment of idiopathic facial paralysis (Bell's palsy), but the effectiveness of additional treatment with an antiviral agent is uncertain. Significant morbidity can be associated with severe cases of Bell's palsy. This review was first published in 2001 and revised several times, most recently in 2009. This version replaces an update of the review in Issue 7 of the Cochrane Library subsequently withdrawn because of an ongoing investigation into the reliability of data from an included study. To assess the effects of antiviral treatments alone or in combination with any other therapy for Bell's palsy. On 7 October 2014 we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE, EMBASE, LILACS, DARE, NHS EED, and HTA. We also reviewed the bibliographies of the identified trials and contacted trial authors and known experts in the field and relevant drug companies to identify additional published or unpublished data. We searched clinical trials registries for ongoing studies. We considered randomised controlled trials or quasi-randomised controlled trials of antivirals with and without corticosteroids versus control therapies for the treatment of Bell's palsy. We excluded trials that had a high risk of bias in several domains. Pairs of authors independently assessed trials for relevance, eligibility, and risk of bias, using standard Cochrane procedures. Ten trials, including 2280 participants, met the inclusion criteria and are included in the final analysis. Some of the trials were small, and a number were at high or unclear risk of bias. Other trials did not meet current best standards in allocation concealment and blinding. Incomplete recoveryWe found a significant benefit from adding antivirals to corticosteroids in comparison with corticosteroids alone for people with Bell's palsy (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.39 to 0.97, n = 1315).

    2017-01-01

    The Belle II experiment is mainly designed to investigate the decay of B meson pairs from $\\Upsilon(4S)$ decays, produced by the asymmetric electron-positron collider SuperKEKB. The determination of the B meson flavor, so-called flavor tagging, plays an important role in analyses and can be inferred in many cases directly from the final state particles. In this talk a successful approach of B meson flavor tagging utilizing a Deep Neural Network is presented. Monte Carlo studies show a significant improvement with respect to the established category-based flavor tagging algorithm.

    Full Text Available After painstaking investigations carried out since 1994, the bell tower of the San Giovanni Battista Cathedral in Monza (Milan has recently been subject to conservation interventions. Severe deterioration phenomena were detected involving the global stability of the tower but particularly related with the properties and behaviour of the materials. The intervention has therefore been designed on the basis of a complex process of knowledge, carried out by means of in situ and laboratory experiments and tests which led the restorers to decide on minimum repair and strengthening techniques aimed at solving the specific structural deficiencies while showing the maximum respect for the historic identity of the building.

    Based on the Bardeen-Cooper-Schrieffer theory of superconductivity, the coherent splitting of Cooper pairs from a superconductor to two spatially separated quantum dots has been predicted to generate nonlocal pairs of entangled electrons. In order to test this hypothesis, we propose a scheme to transfer the spin state of a split Cooper pair onto the polarization state of a pair of optical photons. We show that the photon pairs produced can be used to violate a Bell inequality, unambiguously demonstrating the entanglement of the split Cooper pairs.

    Sylvia Plath's well-known novel, The Bell Jar, recounts her experience of a severe depressive episode. In the novel, the protagonist is treated with electroconvulsive therapy (ECT), as was Plath in life. The first ECT is given in the now-obsolete "unmodified" form, without general anesthesia. Later in the story, she receives ECT again, this time with full general anesthesia and muscle relaxation, as is the standard of care today. This chapter examines how the novelistic descriptions of the treatment compare with actual clinical practice. © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Amplitude Analysis of two photon production of ππ and K¯K, using S-matrix constraints and fitting all available data, including the latest precision results from Belle, yields a single partial wave solution up to 1.4 GeV. The two photon couplings of the σ/f0(500, f0(980 and f2(1270 are determined from the residues of the resonance poles. These amplitudes are a key input into the newly developed dispersive approach to calculating hadronic light-by-light scattering for (g−2 of the muon.

    In this paper, we propose a new secure quantum group signature with Bell states, which may have applications in e-payment system, e-government, e-business, etc. Compared with the recent quantum group signature protocols, our scheme is focused on the most general situation in practice, i.e. only the arbitrator is trusted and no intermediate information needs to be stored in the signing phase to ensure the security. Furthermore, our scheme has achieved all the characteristics of group signature—anonymity, verifiability, traceability, unforgetability and undeniability, by using some current developed quantum and classical technologies. Finally, a feasible security analysis model for quantum group signature is presented.

    The sound of church bells is part of most people's everyday life and can easily be examined with smartphones. Similar to other experiments of this column, we use a suitable iOS app. The underlying physical theory of church bells proves to be difficult. A reliable prediction of their natural frequencies based on their exact dimensions is only possible using the finite element method. If you ask bell founders how they calculate the rib of a bell (half longitudinal section of a bell, which completely determines the acoustic properties, Fig. 1) in order to get a church bell with the desired frequency spectrum, you will certainly not get an answer: the art of bell casting is based on centuries of experience and knowledge of the rib structure is only shared with direct descendants. We want to have a closer look at these well-guarded secrets, knowing full well that we cannot fully unravel them. This article presents simple mathematical models and a comparison with a data set of almost 700 bells.

    1997-04-01

    Mathematical models of the human thermoregulatory system have been used to make predictions of the likely survival of divers in a ``lost bell`` who can be exposed to very low ambient temperatures. The circumstances considered are not the most extreme but those where, partly by shivering, the individual can re-enter thermal balance. The ability accurately to predict the level and duration of metabolic heat production is critical for the estimation of survival time under these conditions. Limitations on the accuracy of current models arise from the lack of precision in modelling the intensity and duration of the metabolic (shivering) response. A different basis for predicting shivering endurance using the time to hypogylcaemia (blood glucose level less than 2.5 mmol/1) is proposed. This leads to predicted survival times ranging from 10 to over 24 hours for those individuals able to stabilise deep body temperature. This seems to be more consistent with the limited experimental data which exists than the 8-9 hours predicted by other models. In order to help maintain blood sugar levels, and hence metabolic heat production, it is recommended that emergency rations within bells should provide 500g of carbohydrate a day.

    Media gather at the KSC Visitor Complex for the kickoff of the Discovery Channel's Liberty Bell 7 Space Capsule Exhibit, which will open to the public on Saturday, June 17. At the podium is Mike Quattrone, executive vice president and general manager, Discovery Channel. Standing to the left of the podium is Rick Abramson, president and chief operating officer of Delaware North Parks Services of Spaceport, Inc., and far left, Jim Jennings, deputy director of Kennedy Space Center. Liberty Bell 7 launched U.S. Air Force Captain Virgil '''Gus''' Grissom July 21, 1961 on a mission that lasted 15 minutes and 37 seconds before sinking to the floor of the Atlantic Ocean, three miles deep. It lay undetected for nearly four decades before a Discovery Channel expedition located it and recovered it.

  13. ZoBell and his contributions to petroleum microbiology

    Bass, C. [Exeter Univ., Exeter (United Kingdom)

    2000-07-01

    The unique contributions that microbiologist Claude ZoBell has made toward the advancement of knowledge in petroleum microbiology was discussed. His research from 1938 to 1978 has provided opportunity for improved oil recovery, modification of petroleum products, knowledge of subsurface microbiology and remediation of polluted environments. Much of his work focused on the key role of microorganisms in the diagenesis of hydrocarbon products and in enhanced oil recovery. Petroleum microbiology is divided into the following six broad areas: (1) diagenesis of organic components in sediments and subsequent oleogenesis, (2) degradation of hydrocarbons, (3) improved recovery of hydrocarbons from reservoirs, (4) modification of hydrocarbon products in formation or post production, (5) mitigation of the effects of 'nuisance organisms' during production, and (6) bioremediation of escaped crude or processed product. ZoBell recognized that oil recovery could be improved using bacterial products such as acids and gases to help mobilisation and as a control agent in oil spill pollution. 26 refs.

  14. The Exponential Decay Law, Bell's Inequality, and Nonlinear Dynamics

    McHarris, Wm. C.

    2002-10-01

    What do the exponential decay law and Bell's inequality have in common? And with nonlinear dynamics? Simply that they both are among the puzzles at the heart of quantum mechanics, puzzles which can have parallel explanations in terms of chaos or nonlinear dynamics. The statistical nature of the exponential decay law, which at first glance is incompatible with the quantum mechanical concept of indistinguishabe particles, can be mocked up by the extreme sensitivity of chaotic systems to initial conditions. In accord with Ockham's Razor, iteration of a simple unimodal (e.g., quadratic) map in its chaotic region and keeping track of the number of iterations required for a trajectory starting from a point chosen at random within a small interval to escape into another small small interval reproduces the observed exponential behavior. Similarly, Bell's inequality derived using classical mechanics (with an underlying assumption of classical statistics) places an upper limit on numbers derived from measurements on entangled states, whereas quantum mechanics implies that this upper limit no longer holds. Experiments have shown the inequality to be violated, upholding quantum mechanics. However, nonlinear dynamics, with its correlated statistics, can yield results overlapping with the quantum mechanical predictions. Whether or not the experiments rule out "local realism" is thus a moot point. Nonlinear determinism just might exist within quantum mechanics.

  15. A Bell inequality for a class of multilocal ring networks

    Science.gov (United States)

    Frey, Michael

    2017-11-01

    Quantum networks with independent sources of entanglement (hidden variables) and nodes that execute joint quantum measurements can create strong quantum correlations spanning the breadth of the network. Understanding of these correlations has to the present been limited to standard Bell experiments with one source of shared randomness, bilocal arrangements having two local sources of shared randomness, and multilocal networks with tree topologies. We introduce here a class of quantum networks with ring topologies comprised of subsystems each with its own internally shared source of randomness. We prove a Bell inequality for these networks, and to demonstrate violations of this inequality, we focus on ring networks with three-qubit subsystems. Three qubits are capable of two non-equivalent types of entanglement, GHZ and W-type. For rings of any number N of three-qubit subsystems, our inequality is violated when the subsystems are each internally GHZ-entangled. This violation is consistently stronger when N is even. This quantitative even-odd difference for GHZ entanglement becomes extreme in the case of W-type entanglement. When the ring size N is even, the presence of W-type entanglement is successfully detected; when N is odd, the inequality consistently fails to detect its presence.

    After 10 years of successful operation, the Belle experiment at KEK (Tsukuba, Japan) will be completed in 2010. Thereafter, a major upgrade of the KEK-B machine is foreseen until 2014, aiming at a final luminosity of 8×10 35 cm -2 s -1, which is about 40 times higher than the present peak value. Consequently, also the Belle experiment needs to be changed and the Silicon Vertex Detector (SVD) in particular will be completely replaced as it already operates close to its limits in the present system. The future SVD (a.k.a. SuperSVD) will consist of four layers of double-sided silicon strip detectors like the present one, but at larger radii, because it will be complemented by a two-layer pixel detector as the innermost sensing device. The SuperSVD will be entirely composed of silicon sensors made from 6 in. wafers read out by APV25 front-end chips that were originally developed for the CMS experiment at the LHC. Several years of R&D effort led to innovations such as the Origami chip-on-sensor concept and readout electronics with hit time finding which were successfully demonstrated on prototypes. These features will be included in the final system which is presently being designed. This paper will give an overview of the SuperSVD and present results from prototype tests ranging from detector modules to back-end electronics.

  17. Virginia Woolf, Vanessa Bell, the maternal and photography

    Full Text Available Photographs preserve relationships. Any photo album's sequencing of photographs creates meaning out of random events. In this respect, albums are memories constructed in the present, but the principles of selection, montage and tableau in albums are the skeleton of a story. Psychoanalytically speaking, albums are often a testimony to our unconscious pasts rather than the pasts we consciously choose to remember. All photographs are a language and Woolf's language was maternal. `She has haunted me', Woolf wrote many years after her mother Julia’s death at 49, when Woolf was 13. I will argue that the death of her mother gave Woolf a visual blueprint. In 'Moments of Being', Woolf describes how it was her mother's death that `made me suddenly develop perception'. Woolf’s sister, the artist Vanessa Bell, also used the maternal as a `framing-structure' in her paintings and photographs. As Andre Green argues, a child can project its feelings back onto the mother through `revivifying repetitions'. Vanessa’s paintings taught Woolf that representations can resist death. In 'Vanessa Bell', a review of her sister’s exhibition, Woolf spoke of `this strange painter’s world, in which mortality does not enter and psychology is held at bay'. The photomontages in both sisters’ albums similarly suggest the pressure of the ‘matrixial’, as Ettinger suggests. I will argue that both sisters 'refuse' their mother’s death by constantly revivifying the maternal in art.

    Full Text Available In desalination process, besides the potable water, highly salty and pollutant water (brine is generated, which can be used for producing crops since it is carefully monitored. In order to test this hypothesis, bell pepper plants, cv. 'Margarita', were grown in coconut fiber substrate under greenhouse and were irrigated with nutrient solutions prepared with tap water, brine from desalination plant, and its dilution with tap water at 75, 50 and 25%, giving a range of electrical conductivities of the nutrient solution (ECs of 2.6, 3.1, 6.6, 10.0 and 12.2 dS m-1 after the dilutions and fertilizers addition. Completely randomized blocks design was used with 5 treatments (salinity levels of the nutrient solutions and six replications. Leaf area, number of marketable fruit, total and marketable yield were reduced with ECs increase. The marketable yield of bell pepper 'Margarita' reduced 6.3% for each unitary increase of ECs above 2.6 dS m-1 (threshold salinity and the results suggest that in hydroponic system, the reduction of marketable yield with increasing ECs is promoted by reduction of the number of fruits per plant instead of a reduction of fruit mean weight.

    Urban is one of the three bells in the belfry of St. Trinity Church in Krosno. It is the largest one, with diameter equal to 1,535 mm and it is commonly considered as one of the largest historical bells in Poland. The total mass of all the three bells is close to 4,200 kilograms, so the dynamic actions produced by swinging have a great effect on the supporting structure and on the tower. However, the exact weight of the biggest bell isn't known, and for safety reasons it should be estimated in order to verify the real dynamic forces affecting the structure. The paper describes the method of Urban bell's survey using terrestrial laser scanning and a total station as a task to estimate its weight by determining its volume.

  1. Bells Galore: Oscillations and circle-map dynamics from space-filling fractal functions

    2008-10-15

    The construction of a host of interesting patterns over one and two dimensions, as transformations of multifractal measures via fractal interpolating functions related to simple affine mappings, is reviewed. It is illustrated that, while space-filling fractal functions most commonly yield limiting Gaussian distribution measures (bells), there are also situations (depending on the affine mappings parameters) in which there is no limit. Specifically, the one-dimensional case may result in oscillations between two bells, whereas the two-dimensional case may give rise to unexpected circle map dynamics of an arbitrary number of two-dimensional circular bells. It is also shown that, despite the multitude of bells over two dimensions, whose means dance making regular polygons or stars inscribed on a circle, the iteration of affine maps yields exotic kaleidoscopes that decompose such an oscillatory pattern in a way that is similar to the many cases that converge to a single bell.

  2. Sensors, motes, and smart dust : WirelessHART sensors are finding application in gas plants, well rigs and soon may be embraced by entire cities

    The WirelessHART (Highway Addressable Remote Transducer) is wireless communication system designed to address the needs of the process industry. The sensor system can be used in applications that were previously not practical or possible, such as in drilling rigs and gas plants. The wireless aspect is an important new innovation that delivers key economic benefits. For some temperature measurements in industrial plants, it is not always feasible to run wires all the way up the stack. The wireless solution consists of wireless gateways and field devices that receive and condition data from sensors that measure temperatures, pressures, flow rates, vibration, and other process parameters. The same devices also relay the measurement data to the gateway. Up to 100 devices can be linked wirelessly to a gateway, which passes on the process information to the control system of the plant, drilling rig, or other industrial facility. Multiple networks can be bridged using Wi-Fi. Once deployed, the technology optimizes itself. The system is also useful for determining temperatures and pressures on the mud tanks at drilling rigs and blowout preventers. The system is being used in highly automated and multi-process plants like refineries and upgraders where numerous sensors are needed. Savings on the wireless installations allow a company to afford the installation of more sensors in places they previously could not cost-effectively deploy wired sensors, thereby resulting in improved productivity, safety, and reduced plant downtimes. Talisman Energy's Teepee Creek sour gas plant near Grande Prairie Alberta uses the WirelessHART network to measure temperatures, pressure, differential pressure, tank levels, and valve positions. 4 figs.

    When separated measurements on entangled quantum systems are performed, the theory predicts correlations that cannot be explained by any classical mechanism: communication is excluded because the signal should travel faster than light; preestablished agreement is excluded because Bell inequalities are violated. All optical demonstrations of such violations have involved discrete degrees of freedom and are plagued by the detection-efficiency loophole. A promising alternative is to use continuous variables combined with highly efficient homodyne measurements. However, all the schemes proposed so far use states or measurements that are extremely difficult to achieve, or they produce very weak violations. We present a simple method to generate large violations for feasible states using both photon counting and homodyne detections. The present scheme can also be used to obtain nonlocality from easy-to-prepare Gaussian states (e.g., two-mode squeezed state).

    Full Text Available The preliminary study, project and restoration process of the bell tower of the Frari church in Venice is an exemplary case of intervention on a historic building. This intervention started within depth research into the documentary data along with a detailed study of the material fabric which has made it possible to compare the verisimilitude and gaps in the historic sources, the evolution of the building, its built reality and the effects of the repair works carried out in the past at the same time as the damages in the fabric were monitored. Thanks to the knowledge thus gleaned, the restoration works proceeded with great caution in order to respect the material history of the building and short and long-term structural compatibility.

    This paper describes the muon identification method and its performance in the Belle experiment at KEKB. Muon and hadron likelihood are calculated for each track using its range and transverse scattering in the K sub L -and-muon detector (KLM). We apply a cut on the normalized muon likelihood L submu to identify the track as a muon. Above the detection threshold of 0.6 GeV/c, the measured muon detection efficiency and pion fake rate are approximately constant for momenta greater than 1.0 and 1.5 GeV/c, respectively. Between 1.0 and 3.0 GeV/c, the averaged muon detection efficiency is 89% and the pion fake rate per track is 1.4% over the KLM acceptance, using the standard selection criterion L submu>0.9.

    The silicon vertex detector of the Belle II experiment, structured in a lantern shape, consists of four layers of ladders, fabricated from two to five silicon sensors. The APV25 readout ASIC chips are mounted on one side of the ladder to minimize the signal path for reducing the capacitive noise; signals from the sensor backside are transmitted to the chip by bent flexible fan-out circuits. The ladder is assembled using several dedicated jigs. Sensor motion on the jig is minimized by vacuum chucking. The gluing procedure provides such a rigid foundation that later leads to the desired wire bonding performance. The full ladder with electrically functional sensors is consistently completed with a fully developed assembly procedure, and its sensor offsets from the design values are found to be less than 200 μm. The potential functionality of the ladder is also demonstrated by the radioactive source test.

    A two layer highly granular DEPFET pixel detector will be operated as the innermost subsystem of the Belle II experiment, at the new Japanese super flavor factory (SuperKEKB). Such a finely segmented system will allow to improve the vertex reconstruction in such ultra high luminosity environment but, at the same time, the raw data stream generated by the 8 million pixel detector will exceed the capability of real-time processing due to its high rate. For this reason a new ASIC, the Data Handling Processor (DHP) is designed to provide full functionality of data processing at the level of the front-end electronics and to cover the task of controling the pixel read-out scheme. In this contribution, the description of the latest prototype chip in TSMC 65 nm technology together with the latest test results of the interface functionality are presented.

    For the Belle II spectrometer we are preparing a proximity focusing RICH with aerogel as the radiator. It will be positioned in the forward direction of the spectrometer in the small space between the drift chamber and the electromagnetic calorimeter inside a strong magnetic field of 1.5 T. The Hybrid Avalanche Photo Diode used as a photo sensor, is able to detect single photons with a high efficiency, can operate in the magnetic field and is resistant to the expected neutron and gamma fluxes in the detector. By detecting more than 11 photons per incident 4 GeV/c pion, with 15 mrad single photon Cherenkov angle resolution, the designed aerogel RICH should enable an efficient separation of kaons from pions in the wide range of particle momenta from 0.5 GeV/c up to 4 GeV/c.

  10. Cyanea capillata bell kinematics analysis through corrected in situ imaging and modeling using strategic discretization techniques.

    Directory of Open Access Journals (Sweden)

    Alex A Villanueva

    Full Text Available Obtaining accurate kinematic data of animals is essential for many biological studies and bio-inspired engineering. Many animals, however, are either too large or too delicate to transport to controlled environments where accurate kinematic data can be easily obtained. Often, in situ recordings are the only means available but are often subject to multi-axis motion and relative magnification changes with time leading to large discrepancies in the animal kinematics. Techniques to compensate for these artifacts were applied to a large jellyfish, Cyanea capillata, freely swimming in ocean waters. The bell kinematics were captured by digitizing exumbrella profiles for two full swimming cycles. Magnification was accounted for by tracking a reference point on the ocean floor and by observing the C. capillata exumbrella arclength in order to have a constant scale through the swimming cycles. A linear fit of the top bell section was used to find the body angle with respect to the camera coordinate system. Bell margin trajectories over two swimming cycles confirmed the accuracy of the correction techniques. The corrected profiles were filtered and interpolated to provide a set of time-dependent points along the bell. Discrete models of the exumbrella were used to analyze the bell kinematics. Exumbrella discretization was conducted using three different methods. Fourier series were fitted to the discretized models and subsequently used to analyze the bell kinematics of the C. capillata. The analysis showed that the bell did not deform uniformly over time with different segments lagging behind each other. Looping of the bell trajectory between contraction and relaxation was also present through most of the exumbrella. The bell margin had the largest looping with an outer path during contraction and inner path during relaxation. The subumbrella volume was approximated based on the exumbrella kinematics and was found to increase during contraction.

    Ethnographic methods can provide insights into patients' perceptions of quality of care. We used ethnographic methods to examine problems related to answering patient call lights on one inpatient unit in the hospital. Communication through call bells consisted of 3 interrelated components. These included answering the call bell, communicating the patient's request, and following through with the request. Results of this study provided a deeper understanding of the nuances of power and control embedded within the issue of patient-caregiver communication and empowered unit staff to find solutions to the call bell problem.

  18. Full Bell locality of a noisy state for N ⩾ 3 nonlocally entangled qudits

    Bounds, expressed in terms of d and N, on full Bell locality of a quantum state for N≥slant 3 nonlocally entangled qudits (of a dimension d≥slant 2 ) mixed with white noise are known, to our knowledge, only within full separability of this noisy N-qudit state. For the maximal violation of general Bell inequalities by an N-partite quantum state, we specify the analytical upper bound expressed in terms of dilation characteristics of this state, and this allows us to find new general bounds in d, N, valid for all d≥slant 2 and all N≥slant 3, on full Bell locality under generalized quantum measurements of (i) the N-qudit GHZ state mixed with white noise and (ii) an arbitrary N-qudit state mixed with white noise. The new full Bell locality bounds are beyond the known ranges for full separability of these noisy N-qudit states.

    Yang, W. L.; Wei, H; Zhang, X. L.; Feng, M.

    2008-01-01

    We propose a potentially practical scheme, in combination with the Bell-state analyzer [Zhang et al., Phys. Rev. A 73, 014301 (2006)], to generate Bell states for two electron spins confined, respectively, in two distant fullerenes. To this end, we consider the endohedral fullerenes staying in single walled carbon nanotubes (SWCNTs) and employ auxiliary mobile electrons and selective microwave pulses. The application and the experimental feasibility of our scheme are discussed.

    We perform Bell's measurement for the non-separable correlation between polarization and orbital angular momentum from the same classical vortex beam. The violation of Bell's inequality for such a non-separable classical correlation has been demonstrated experimentally. Based on the classical vortex beam and non-quantum entanglement between the polarization and the orbital angular momentum, the Hadamard gates and conditional phase gates have been designed. Furthermore, a quantum Fourier transform has been implemented experimentally.

  8. Biomimetic and live medusae reveal the mechanistic advantages of a flexible bell margin.

    Directory of Open Access Journals (Sweden)

    Sean P Colin

    Full Text Available Flexible bell margins are characteristic components of rowing medusan morphologies and are expected to contribute towards their high propulsive efficiency. However, the mechanistic basis of thrust augmentation by flexible propulsors remained unresolved, so the impact of bell margin flexibility on medusan swimming has also remained unresolved. We used biomimetic robotic jellyfish vehicles to elucidate that propulsive thrust enhancement by flexible medusan bell margins relies upon fluid dynamic interactions between entrained flows at the inflexion point of the exumbrella and flows expelled from under the bell. Coalescence of flows from these two regions resulted in enhanced fluid circulation and, therefore, thrust augmentation for flexible margins of both medusan vehicles and living medusae. Using particle image velocimetry (PIV data we estimated pressure fields to demonstrate a mechanistic basis of enhanced flows associated with the flexible bell margin. Performance of vehicles with flexible margins was further enhanced by vortex interactions that occur during bell expansion. Hydrodynamic and performance similarities between robotic vehicles and live animals demonstrated that the propulsive advantages of flexible margins found in nature can be emulated by human-engineered propulsors. Although medusae are simple animal models for description of this process, these results may contribute towards understanding the performance of flexible margins among other animal lineages.

  9. A numerical study of the benefits of driving jellyfish bells at their natural frequency.

    A current question in swimming and flight is whether or not driving flexible appendages at their resonant frequency results in faster or more efficient locomotion. It has been suggested that jellyfish swim faster when the bell is driven at its resonant frequency. The goal of this study was to determine whether or not driving a jellyfish bell at its resonant frequency results in a significant increase in swimming velocity. To address this question, the immersed boundary method was used to solve the fully coupled fluid structure interaction problem of a flexible bell in a viscous fluid. Free vibration numerical experiments were used to determine the resonant frequency of the jellyfish bell. The jellyfish bells were then driven at frequencies ranging from above and below the resonant frequency. We found that jellyfish do swim fastest for a given amount of applied force when the bells are driven near their resonant frequency. Nonlinear effects were observed for larger deformations, shifting the optimal frequency to higher than the resonant frequency. We also found that the benefit of resonant forcing decreases for lower Reynolds numbers. Published by Elsevier Ltd.

    Coal petrology, palynology, paleobotany and mineralogy of the Hart coal indicate deposition under wet, warm-temperate to subtropical climatic conditions in low-lying backswamps with fluvial channels and locally ponded areas. The coal is dominated by mixed xylitic/attrital lithotypes and by huminite macerals with secondary inertinite macerals and minor liptinite macerals. Good correlation exists between lithotypes and maceral composition. Local and vertical variations in proportions of huminites and inertinites reflect frequent fluctuations in water levels, periodic flooding, desiccation and burning of the peat. Swamps were dominated by {ital Glyptostrobus-Taxodium} forest with {ital Betula-Myrica-Alnus} communities and, locally {ital Laevigatosporites}, which are the dominant contributors to the xylite-rich lithotypes. Attrital lithotypes with abundant {ital Pandanus}, {ital Typha} and {ital Azolla} are consistent with wetter areas of a fluvial environment, including ponds and channels. Trace elements Cr, Cu, Mo, Ni, Si, Ti, U, Se, V, W, K and Th, typically associated with syngenetic minerals kaolinite, calcite and quartz, may have a volcanic source. High concentrations of Na, Ba and Ca found in organic complexes are of secondary origin and probably originate in deep source brines rather than marine surface waters. 55 refs., 11 figs., 5 tabs.

    Bell's palsy (idiopathic facial paralysis) is commonly treated by various physical therapy strategies and devices, but there are many questions about their efficacy. To evaluate physical therapies for Bell's palsy (idiopathic facial palsy). We searched the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2011), MEDLINE (January 1966 to February 2011), EMBASE (January 1946 to February 2011), LILACS (January 1982 to February 2011), PEDro (from 1929 to February 2011), and CINAHL (January 1982 to February 2011). We included searches in clinical trials register databases until February 2011. We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. Two authors independently scrutinised titles and abstracts identified from the search results. Two authors independently carried out risk of bias assessments, which , took into account secure methods of randomisation, allocation concealment, observer blinding, patient blinding, incomplete outcome data, selective outcome reporting and other bias. Two authors independently extracted data using a specially constructed data extraction form. We undertook separate subgroup analyses of participants with more and less severe disability. For this update to the original review, the search identified 65 potentially relevant articles. Twelve studies met the inclusion criteria (872 participants). Four trials studied the efficacy of electrical stimulation (313 participants), three trials studied exercises (199 participants), and five studies compared or combined some form of physical therapy

  13. Bell's Spaceships: The Views from Bow and Stern

    2018-01-01

    Unravelling apparent paradoxes has proven to be a powerful tool for understanding the complexities of special relativity. In this paper, we focus upon one such paradox, namely Bell's spaceship paradox, examining the relative motion of two uniformly accelerating spaceships. We consider the view from either spaceship, with the exchange of photons between the two. This recovers the well-known result that the leading spaceship loses sight of the trailing spaceship as it is redshifted and disappears behind what is known as the `Rindler horizon'. An immediate impact of this is that if either spaceship tries to measure the separation through `radar ranging', bouncing photons off one another, they would both eventually fail to receive any of the photon `pings' that they emit. We find that the view from this trailing spaceship is, however, starkly different, initially, seeing the leading spaceship with an increasing blueshift, followed by a decreasing blueshift. We conclude that, while the leading spaceship loses sight of the trailing spaceship, for the trailing spaceship the view of the separation between the two spaceships, and the apparent angular size of the leading spaceship, approach asymptotic values. Intriguingly, for particular parameterisation of the journey of the two spaceships, these asymptotic values are identical to those properties seen before the spaceships began accelerating, and the view from the trailing spaceship becomes identical to when the two spaceships were initially at rest.

    The Belle II DEPFET pixel detector (PXD) will deliver high data rates of up to 21.6 Gbytes/s for 3% detector occupancy. Data of this high rate must be buffered for 5 seconds, corresponding to the HLT (High Level Trigger) latency, and then a region-of-interest (ROI) filter is applied to reduce the data rate by a factor of ≥10 by charged track extrapolation from other detectors (SVD, CDC). The PXD readout system is based upon ATCA (Advanced Telecommunications Architecture). The 3rd PCB iteration uses a concept with a xTCA carrier board (with a Virtex-4 FX60 FPGA for ATCA backplane routing) and 4 AMC modules (each with a Xilinx Virtex-5 FX70T FPGA). The FPGA firmware implementation comprises a receiver core for the high speed optical links (≤6.25 Gbps), a buffer management with lookup of ≤270.000 pointers/s, DDR2 memory write (native port interface, ≥1.5 Gbytes/s), Gigabit ethernet (UDP stack in VHDL) and a parallelized ROI selection algorithm. Test results of all the components are presented.

    The Belle II PXD readout system (called ONSEN for Online Selection Nodes) uses ATCA (Advanced Telecommunications Architecture) boards with Xilinx Virtex-5 FX70T FPGAs and high speed optical links (6.5 Gbit/s each). The full system consists of 9 carrier boards and 33 daughter cards. The ONSEN system has several interfaces: (a) it receives PXD data from the DHH (Data Handling Hybrid) system, (b) it receives ROI (Regions-of-Interest) data for online data reduction from the HLT (High Level Trigger) system by GbE, and (c) it features data ports to two event builders: EVB1 combines data from all detectors except PXD (in order to generate the ROIs) and EVB2 combines the reduced PXD data with all other data. One of the critical issues is the matching of trigger numbers in the data (received by DHH from the timing distribution system) and trigger numbers in the ROIs (received by the HLT). In order to test the interfaces, in particular for a high HLT rate up to 30 kHz, a prototype system with 3 daughter cards was installed at KEK and tested with DHH, HLT and EVB2. Test results are presented.

    Hormesis, or biological effects of low level exposures (BELLE), is characterized by nonmonotonic dose response which is biphasic, displaying opposite effects at low and high dose. Its occurrence has been documented across a broad range of biological models and diverse type of exposure. Since hormesis appears to be a relatively common phenomenon in many areas, the objective of this review is to explore its occurrence related to dermatology and its public health and risk assessment implication. Hormesis appears to be a common phenomenon in in-vitro skin biology. However, in vivo data are lacking and the clinical relevance of hormesis has yet to be determined. Better understanding of this phenomenon will likely lead to different strategies for risk assessment process employed in the fields of dermatologic toxicology and pharmacology. We believe that hormesis is a common phenomenon and should be given detailed consideration to its concept and its risk assessment implications, and how these may be incorporated into the experimental and regulatory processes in dermatology. The skin, with its unique characteristics, its accessibility, and the availability of non-invasive bioengineering and DNA microarray technology, will be a good candidate to extend the biology of hormesis.

    A two layer highly granular DEPFET pixel detector will be operated as the innermost subsystem of the Belle II experiment, at the new Japanese super flavor factory (SuperKEKB). Such a finely segmented system will allow to improve the vertex reconstruction in such ultra high luminosity environment but, at the same time, the raw data stream generated by the 8 million pixel detector will exceed the capability of real-time processing due to its high frame rate, considering the limited material budged and strict space constrains. For this reason a new ASIC, the Data Handling Processor (DHP) is designed to provide data processing at the level of the front-end electronics, such as zero-suppression and common mode correction. Additional feature of the Data Handling Processor is the control block, providing control signals for the on-module ASICs used in the pixel detector. In this contribution, the description of the latest chip revision in TSMC 65 nm technology together with the latest test results of the interface functionality tests are presented.

    An experiment was carried out under plastic house conditions to compare the effect of four fermented organic matter sources (cattle, poultry and sheep manure in addition to 1:1:1 mixture of the three organic matter sources) in which 4 kg organic matter m(-2) were used, with that of the conventional agriculture (chemical fertilizers) treatments on Marvello red pepper fruit quality, by using a Randomized Complete Block Design (RCBD) with four replicates. Pepper fruits characteristics cultivated in soil supplemented with manure were generally better than those from plants grown in soil only. Addition of animal manure increased bell pepper fruit content of soluble solids, ascorbic acid, total phenols, crude fibre and intensity of red color as compare with conventional agriculture that produced fruits with higher titratable acidity, water content, lycopene and bigger fruit size. In most cases of animal manure treatments, best results were obtained by the sheep manure treatment that produced the highest TSS, while the worst results were obtained by the poultry manure treatment that produced the smallest fruit and lowest fruit lycopene content.

    Health and usage monitoring systems (HUMS) use vibration-based Condition Indicators (CI) to assess the health of helicopter powertrain components. A fault is detected when a CI exceeds its threshold value. The effectiveness of fault detection can be judged on the basis of assessing the condition of actual components from fleet aircraft. The Bell 412 HUMS-equipped helicopter is chosen for such an evaluation. A sample of 20 aircraft included 12 aircraft with confirmed transmission and gearbox faults (detected by CIs) and eight aircraft with no known faults. The associated CI data is classified into "healthy" and "faulted" populations based on actual condition and these populations are compared against their CI thresholds to quantify the probability of false alarm and the probability of missed detection. Receiver Operator Characteristic analysis is used to optimize thresholds. Based on the results of the analysis, shortcomings in the classification method are identified for slow-moving CI trends. Recommendations for improving classification using time-dependent receiver-operator characteristic methods are put forth. Finally, lessons learned regarding OEM-operator communication are presented.

    DEPFET pixel detectors offer intrinsic amplification and very high signal to noise ratio. They form an integral building block for the vertex detector system of the Belle II experiment, which will start data taking in the year 2017 at the SuperKEKB Collider in Japan. A special Test board (Hybrid4) is used, which contains a small version of the DEPFET sensor with a read-out (DCD) and a steering chip (Switcher) attached, both controlled by a field-programmable gate array (FPGA) as the central interface to the computer. In order to keep the luminosity of the collider constant over time, the particle bunch currents have to be topped off by injecting additional bunches at a rate of 50 Hz. The particles in the daughter bunches produce a high rate of background (noisy bunches) for a short period of time, saturating the occupancy of the sensor. Operating the DEPFET sensor in a Gated Mode allows preserving the signals from collisions of normal bunches while protecting the pixels from background signals of the passing noisy bunches. An overview of the Gated Mode and first results is presented.

    Full Text Available The attempts to challenge conventional gendered discourses in children's fantasy have often resulted in feminist rewritings of earlier stories. Ghost dance (1994 by the English author Susan Price is a novel that reflects a specific feminist poetics of rewriting: metafictional passages highlight the constructedness of the narrative and at the end readers are invited to tell their own versions of the story. Moreover, the rewriting freely combines and recontextualises elements from different source texts and reformulates them to create a narrative that challenges conventional discourses of gender. While this poetics has an appeal from a feminist perspective, the play with cross-cultural intertexts and gender becomes more complex when the novel is examined in a postcolonialist framework in relation to ethnicity and the issue of cultural appropriation. Ghost dance is situated in a setting that has a real-world equivalent (Russia, involves characters that are identified with names of real-world ethnic groups (Lapps (Sámi, Russian, and mixes elements from Russian wonder tales, Nordic mythology and an Ojibwe legend. The novel does not aim at historical accuracy in its representations nor is it a direct retelling of any of the pre-texts but combines motifs, themes, names, characters and settings freely from each source. In this textual melting pot, the protagonist Shingebiss is, on one level, a revision of the witch Baba Yaga, but also described as a Lappish shaman with an Ojibwe name. To rewrite gendered discourses, certain elements from the pretexts are chosen and others left out – the question is, then, what effects does this recontextualisation have on the representation of ethnicity? Or, are the feminist rewriting strategies actually a form of cultural appropriation?

    Development of the cement grout for the Bell Canyon Test was accomplished at the US Army Engineer Waterways Experiment Station (WES), Vicksburg, Mississippi. Initial development work centered on a saltwater grout with Class H cement, fly ash, and an expansive additive. Testing of the saltwater grout showed suitable properties except for the interface between anhydrite rock and grout in small core samples. Higher than expected permeability occurred at the interface because of space between the grout and the anhydrite; the space was produced as a result of allowing the specimens to dry. A change to freshwater grout and proper care to prevent the specimens from drying alleviated this condition. The BCT-1FF freshwater grout mixture was used in both the plug ONE and ONEX field grouting operations. Testing of the development grout mixtures was also done at Dowell, Pennsylvania State University, and Oak Ridge National Laboratory. Results of the testing and evaluation by the four laboratories are included in the report. Field batching, mixing, and placement of the grout at the plug locations for both plug ONE and ONEX were satisfactory with adequate quality control. The freshwater grout mixture maintained adequate flow characteristics for pumpability for 3 1/2 h during each of the two field operations. Physical property and expansivity data for the field samples through 90 days' age are in general agreement with laboratory development data. A large number of samples were obtained for inclusion in the long-term durability studies and the geochemical programs. The high-density, low water-cement ratio expansive grout (BCT-1FF) is considered to be an excellent candidate for plugging boreholes at most locations (except through halite sections).

    The main objective of a dual bell nozzle is the enhancement of performances based on the principle of auto-adaptation in accordance with the altitude. Indeed, this system has as advantage the auto-adaptation of the flow for two operating modes (at low and high altitude) without mechanical activation. The principle is theoretically simple but structural forces involved can be significant. In this study, a numerical method for the design of this type of nozzle is developed. On the one hand, it is based on a transonic flow approaches to define the starting line on which the supersonic calculations will be initiated. On the other hand, the method of characteristics is used to draw the base nozzle profile. Knowing that the latter is assimilated as a polynomial of the second degree, its constants are calculated from initial conditions. In order to minimize the weight of this nozzle, its truncation proves necessary; this is performed at a point where the best compromise (weight / performances) was respected. The profile of the second curve is calculated to give a constant wall pressure. This is achieved by using the direct method of characteristics applied for a centered expansion wave that the intensity is P2/P1 at the junction. Once the profile is generated, an analysis of the thermodynamic-parameters evolution (such as: pressure, Mach number) and aerodynamic performances is conducted. For more consistency, our results are compared with numerical databases of ONERA nozzle. Simulations of flow in the nozzle with Ansys 13.0 environment for different types of meshes are presented. Also, to offset the effects of the boundary layer, the simulations were performed by using the k-ω SST turbulence model. The obtained results by the method of characteristics and numerical simulation are compared to the computed results of the literature and it was found good agreement and similarity.

  5. Simultaneous measurements of jellyfish bell kinematics and flow fields using PTV and PIV

    2016-11-01

    A better understanding of jellyfish swimming can potentially improve the energy efficiency of aquatic vehicles or create biomimetic robots for ocean monitoring. Aurelia aurita is a simple oblate invertebrate composed of a flexible bell and coronal muscle, which contracts to eject water from the subumbrellar volume. Jellyfish locomotion can be studied by obtaining body kinematics or by examining the resulting fluid velocity fields using particle image velocimetry (PIV). Typically, swim kinematics are obtained by semi-manually tracking points of interest (POI) along the bell in video post-processing; simultaneous measurements of kinematics and flows involve using this semi-manual tracking method on PIV videos. However, we show that both the kinematics and flow fields can be directly visualized in 3D space by embedding phosphorescent particles in animals free-swimming in seeded environments. Particle tracking velocimetry (PTV) can then be used to calculate bell kinematics, such as pulse frequency, bell deformation, swim trajectories, and propulsive efficiency. By simultaneously tracking POI within the bell and collecting PIV data, we can further study the jellyfish's natural locomotive control mechanisms in conjunction with flow measurements. NSF GRFP.

  6. Translational control by the DEAD Box RNA helicase belle regulates ecdysone-triggered transcriptional cascades.

    Directory of Open Access Journals (Sweden)

    Robert J Ihry

    Full Text Available Steroid hormones act, through their respective nuclear receptors, to regulate target gene expression. Despite their critical role in development, physiology, and disease, however, it is still unclear how these systemic cues are refined into tissue-specific responses. We identified a mutation in the evolutionarily conserved DEAD box RNA helicase belle/DDX3 that disrupts a subset of responses to the steroid hormone ecdysone during Drosophila melanogaster metamorphosis. We demonstrate that belle directly regulates translation of E74A, an ets transcription factor and critical component of the ecdysone-induced transcriptional cascade. Although E74A mRNA accumulates to abnormally high levels in belle mutant tissues, no E74A protein is detectable, resulting in misregulation of E74A-dependent ecdysone response genes. The accumulation of E74A mRNA in belle mutant salivary glands is a result of auto-regulation, fulfilling a prediction made by Ashburner nearly 40 years ago. In this model, Ashburner postulates that, in addition to regulating secondary response genes, protein products of primary response genes like E74A also inhibit their own ecdysone-induced transcription. Moreover, although ecdysone-triggered transcription of E74A appears to be ubiquitous during metamorphosis, belle-dependent translation of E74A mRNA is spatially restricted. These results demonstrate that translational control plays a critical, and previously unknown, role in refining transcriptional responses to the steroid hormone ecdysone.

    For more than a half-century, several types of altitude-compensating rocket nozzles have been proposed and analyzed, but very few have been adequately tested in a relevant flight environment. One type of altitude-compensating nozzle is the dual-bell rocket nozzle, which was first introduced into literature in 1949. Despite the performance advantages that have been predicted, both analytically and through static test data, the dual-bell nozzle has still not been adequately tested in a relevant flight environment. This paper proposes a method for conducting testing and research with a dual-bell rocket nozzle in a flight environment. We propose to leverage the existing NASA F-15 airplane and Propulsion Flight Test Fixture as the flight testbed, with the dual-bell nozzle operating during captive-carried flights, and with the nozzle subjected to a local flow field similar to that of a launch vehicle. The primary objective of this effort is not only to advance the technology readiness level of the dual-bell nozzle, but also to gain a greater understanding of the nozzle mode transitional sensitivity to local flow-field effects, and to quantify the performance benefits with this technology. The predicted performance benefits are significant, and may result in reducing the cost of delivering payloads to low-Earth orbit.

    Single pulse laboratory experiments were carried out with a high-power CO2 Transversely-Excited Atmospheric (TEA) laser using three laser pulsejet engines, shaped as parabolic bells, measuring 11-cm in diameter. Assuming the vertex is set at the parabola's focus, the "calibration bell" engines had three different total divergence angles of 60, 87.2, and 120 degrees (i.e., viewing outward towards the 11-cm nozzle exit plane). The objective was to quantify and calibrate the effects of laser pulse duration upon the momentum coupling coefficient (Cm) performance from the two CO2 lasers, using laser pulse energy as the parametric variable. Bell engine performance data from the TEA laser are contrasted with former results from the PLVTS CO2 electron discharge laser (EDL). The single-pulse PLVTS tests were conducted in Sept. 2000 and Sept. 2001, revealing that the impulse and Cm performance of the 60° bell generally exceeded the 87.2° engine, which in turn outperformed the 120° bell. With PLVTS, the maximum single-pulse Cm varied from 275 to 375 N-sec/MJ. In contrast, the 2 microsecond TEA laser tests generated results that were distinctively different from that of the EDL. Both tests used a standard ballistic pendulum to measure airbreathing engine performance at a pressure of one atmosphere.

  9. Quasi-Bell inequalities from symmetrized products of noncommuting qubit observables

    2017-05-01

    Noncommuting observables cannot be simultaneously measured; however, under local hidden variable models, they must simultaneously hold premeasurement values, implying the existence of a joint probability distribution. We study the joint distributions of noncommuting observables on qubits, with possible criteria of positivity and the Fréchet bounds limiting the joint probabilities, concluding that the latter may be negative. We use symmetrization, justified heuristically and then more carefully via the Moyal characteristic function, to find the quantum operator corresponding to the product of noncommuting observables. This is then used to construct Quasi-Bell inequalities, Bell inequalities containing products of noncommuting observables, on two qubits. These inequalities place limits on the local hidden variable models that define joint probabilities for noncommuting observables. We find that the Quasi-Bell inequalities have a quantum to classical violation as high as 3/2 on two qubit, higher than conventional Bell inequalities. The result demonstrates the theoretical importance of noncommutativity in the nonlocality of quantum mechanics and provides an insightful generalization of Bell inequalities.

    Full Text Available Nowadays, some frameworks like Arcane and Dune offer a number of advanced tools to deal with the complexity related to parallelism, meshes and linear solvers. However, they do not handle the high level complexity related to discretization methods and physical models. Generative programming and Domain Specific Languages (DSL are key technologies allowing to write code with a high level expressive language and take advantage of the efficiency of generated code with low level services. DSL may be embedded in host languages like Python or C++. Such languages, named in that case Domain Specific Embedded Languages (DSEL, are applied for instance in frameworks like Fenics or Feel++ which are dedicated to the domain of Finite Element (FE methods and Galerkin methods. ArcFVDSL is a DSEL developed on top of the Arcane framework, aiming to implement various lowest order methods (Finite-Volume (FV, Mimetic Finite Difference (MFD, Mixed Hybrid Finite Volume (MHFV, etc. for diffusive problems on general meshes. In this paper, we present various implementations of different complex academic problems. We focus on the capability of the language to allow the description and the resolution of these problems with several lowest-order methods. We illustrate the benefits of such technology combined to runtime system tools like Heterogeneous Abstract RunTime System (HARTS and its ability to handle seamlessly new heterogeneous architectures with multi-core processors enhanced by General Purpose computing on Graphics Processing Units (GP-GPU. We present the performance results of each implementation on different kinds of heterogeneous hardware architecture.

  14. Development and validation of a model for the response of the Belle II vertex detector

    CERN Document Server

    Schwenker, Benjamin

    The future super flavour factory SuperKEKB with its detector system Belle II offers precision physics measurements to test the Standard Model or probe undiscovered phenomena. The physics goals of Belle II require a very precise detection of the decay point, or vertex, of B mesons from their low momentum decay products. A novel, two layer vertex detector composed of very thin, high resolution silicon pixel detectors based on Depleted Field Effect Transistors (DEPFET) is in production for Belle II. A realistic and experimentally validated simulation for DEPFET pixel detectors is a crucial tool to optimize the resolution of the vertex detector well before construction. In this thesis, a detailed detector simulation for the response of thin DEPFET pixel detectors to charged particles is presented. The detector simulation provides a description of the straggling of particles in silicon, the drift, diffusion and collection of the signal and the response of the read-out electronics. The model yields a precise predic...

  15. Constrained Ordination Analysis with Enrichment of Bell-Shaped Response Functions.

    Directory of Open Access Journals (Sweden)

    Yingjie Zhang

    Full Text Available Constrained ordination methods aims at finding an environmental gradient along which the species abundances are maximally separated. The species response functions, which describe the expected abundance as a function of the environmental score, are according to the ecological fundamental niche theory only meaningful if they are bell-shaped. Many classical model-based ordination methods, however, use quadratic regression models without imposing the bell-shape and thus allowing for meaningless U-shaped response functions. The analysis output (e.g. a biplot may therefore be potentially misleading and the conclusions are prone to errors. In this paper we present a log-likelihood ratio criterion with a penalisation term to enforce more bell-shaped response shapes. We report the results of a simulation study and apply our method to metagenomics data from microbial ecology.

  16. Bell's palsy: the answer to the riddle of Leonardo da Vinci's 'Mona Lisa'.

    2011-05-01

    The smile of the famed portrait 'The Mona Lisa' has perplexed both art historians and researchers for the past 500 years. There has been a multitude of theories expounded to explain the nature of the model's enigmatic smile. The origin of the model's wry smile can be demonstrated through a careful analysis of both documented facts concerning the portrait--some gathered only recently through the use of modern technology--and a knowledge of the clinical presentation of Bell's palsy. Bell's palsy is more prevalent in women who are either pregnant or who have recently given birth. This paper postulates that the smile of the portrait's model was due to Leonardo da Vinci's anatomically precise representation of a new mother affected by Bell's palsy subsequent to her recent pregnancy.

    Quantum nonlocality has been experimentally investigated by testing different forms of Bell's inequality, yet a loophole-free realization has not been achieved up to now. Much less explored are temporal Bell inequalities, which are not subject to the locality assumption, but impose a constraint on the system's time correlations. In this Letter, we report on the experimental violation of a temporal Bell's inequality using a nitrogen-vacancy (NV) defect in diamond and provide a novel quantitative test of quantum coherence. Such a test requires strong control over the system, and we present a new technique to initialize the electronic state of the NV with high fidelity, a necessary requirement also for reliable quantum information processing and/or the implementation of protocols for quantum metrology. © 2011 American Physical Society

  18. Partial Bell-State Analysis with Parametric down Conversion in the Wigner Function Formalism

    Directory of Open Access Journals (Sweden)

    A. Casado

    2010-01-01

    Full Text Available We apply the Wigner function formalism to partial Bell-state analysis using polarization entanglement produced in parametric down conversion. Two-photon statistics at a beam-splitter are reproduced by a wave-like description with zeropoint fluctuations of the electromagnetic field. In particular, the fermionic behaviour of two photons in the singlet state is explained from the invariance on the correlation properties of two light beams going through a balanced beam-splitter. Moreover, we show that a Bell-state measurement introduces some fundamental noise at the idle channels of the analyzers. As a consequence, the consideration of more independent sets of vacuum modes entering the crystal appears as a need for a complete Bell-state analysis.

    Peripheral facial nerve palsy (Bell' palsy, BP) is a not rare diseases in children, being the most common acquired mononeuropathy. The authors of this study wanted to determine whether the occurrence and course of paralysis changed in the past 5 years (2010-2014). The study involved Lesser Poland region, where the majority of children with paralysis are hospitalized at the Pediatric Neurology Department of University Children's Hospital in Krakow. These children in subsequent years were admitted to our department without any limitations. A review of clinical documentation of 125 patients, in terms of demographics, the coexistence of other diseases, seasonality, the degree of paralysis, location of paralysis, the prevalence of the recurrence was made. Changes in the structure of the nerve VII in MRI and CT, pharmacological treatment, applied rehabilitation, the degree of improvement and time of hospitalization were analyzed. Similar distribution of occurrence and gender of children with BP in Lesser Poland region within 5 years were observed. The predominance of the girls resulted from demographic composition of the population. BP occurred most frequently in summer and winter. In more than half of children BP occurred in the course of acute systemic infection or craniofacial infection and in 5/125 BP followed head injury. Children with infections required antibiotic therapy. Left-sided paralysis was found in the majority of children and almost half of patients needed protection of the cornea of the eye (significant degree). In 12% of children structural changes within the facial nerve were found. In these children antiviral treatment was used and hospitalization time was more than 20 days while in the majority of children hospitalization lasted 15 days. In 8 (6.4%) children with recurrent BP kinezytherapy, electrical stimulation and laser therapy were applied. Steroid therapy was not used. Only 7/125 chil. dren had mild impairment of the eye closing at the discharge

    The exploitation of volunteer computing resources has become a popular practice in the HEP computing community as the huge amount of potential computing power it provides. In the recent HEP experiments, the grid middleware has been used to organize the services and the resources, however it relies heavily on the X.509 authentication, which is contradictory to the untrusted feature of volunteer computing resources, therefore one big challenge to utilize the volunteer computing resources is how to integrate them into the grid middleware in a secure way. The DIRAC interware which is commonly used as the major component of the grid computing infrastructure for several HEP experiments proposes an even bigger challenge to this paradox as its pilot is more closely coupled with operations requiring the X.509 authentication compared to the implementations of pilot in its peer grid interware. The Belle II experiment is a B-factory experiment at KEK, and it uses DIRAC for its distributed computing. In the project of BelleII@home, in order to integrate the volunteer computing resources into the Belle II distributed computing platform in a secure way, we adopted a new approach which detaches the payload running from the Belle II DIRAC pilot which is a customized pilot pulling and processing jobs from the Belle II distributed computing platform, so that the payload can run on volunteer computers without requiring any X.509 authentication. In this approach we developed a gateway service running on a trusted server which handles all the operations requiring the X.509 authentication. So far, we have developed and deployed the prototype of BelleII@home, and tested its full workflow which proves the feasibility of this approach. This approach can also be applied on HPC systems whose work nodes do not have outbound connectivity to interact with the DIRAC system in general.

    This paper presents the re-creation of the bell deformation cycle of the Aequorea victoria jellyfish. It focuses on the design, fabrication, and characterization of the bio-inspired bell kinematics of an IPMC actuated robotic jellyfish. The shape and bell kinematics of this underwater vehicle are based on the Aequorea victoria jellyfish. This medusa is chosen as a model system based on a comparative bell kinematics study that is conducted among different jellyfish species. Aequorea victoria is known by its low swimming frequency, small bell deformation, and high Froude efficiency (95%). Different methods of implementing the actuators underneath the bell with smaller IPMC actuators are investigated to replicate the natural jellyfish's bell deformation. Results demonstrates that proper placement of the IPMC actuators results in bell configuration that more accurately represents the deformation properties of the natural jellyfish. Smaller IPMC actuators are used to achieve the desired deformation and thus the power consumption is reduced by 70% compared to previous generations. A biomimetic jellyfish robot prototype is built, and its ability to swim and produce thrust with smaller IPMC actuators is shown. The robot swam with four actuators swam at an average speed 0.77 mm/s and consumed 0.7 W. When eight actuators were used the average speed increased to 1.5 mm/s with a power consumption of 1.14 W.

    2013-01-01

    Full Text Available Based on a previously published exposure-effect model of Electroencephalography (EEG-awakening reactions (AWR due to nightly church bell noise events, as well as on geocoded building and population data, we estimated the total number of the church bell noise induced awakenings on the population of the Canton of Zurich, in Switzerland. The calculated mean number of EEG awakenings per person in the studied region, triggered by church bell ringing, varied between 0 and about 5.5 per night. The results suggest that up to 120-150 m distance from churches, on average more than one additional EEG awakening occurs per night per person. An estimated 2.5-3.5 percent of the population in the Canton of Zurich experiences at least one additional awakening per night due to church bell noise. To provide a simple decision support tool for authorities that consider limiting bell ringing in the night in some form, we simulated different scenarios to estimate the effects of different sound attenuation measures at the belfry as well as the effects of different lengths and positions of nocturnal bell ringing suspension periods. The number of awakenings could be reduced by more than 99 percent by, for example, suspending church bell ringing between midnight and 06 h in the morning. A reduction of the number of AWRs of about 75 percent could be achieved by reducing the sound-pressure levels of bells by 5 dB.

    The dual-bell rocket nozzle was first proposed in 1949, offering a potential improvement in rocket nozzle performance over the conventional-bell nozzle. Despite the performance advantages that have been predicted, both analytically and through static test data, the dual-bell nozzle has still not been adequately tested in a relevant flight environment. In 2013 a proposal was constructed that offered a National Aeronautics and Space Administration (NASA) F-15 airplane as the flight testbed, with the plan to operate a dual-bell rocket nozzle during captive-carried flight. If implemented, this capability will permit nozzle operation into an external flow field similar to that of a launch vehicle, and facilitate an improved understanding of dual-bell nozzle plume sensitivity to external flow-field effects. More importantly, this flight testbed can be utilized to help quantify the performance benefit with the dual-bell nozzle, as well as to advance its technology readiness level. Toward this ultimate goal, this report provides plans for future flights to quantify the external flow field of the airplane near the nozzle experiment, as well as details on the conceptual design for the dual-bell nozzle cold-flow propellant feed system integration within the NASA F-15 Propulsion Flight Test Fixture. The current study shows that this concept of flight research is feasible, and could result in valuable flight data for the dual-bell nozzle.

    Full Text Available After the collapse of some heavy buildings and towers in Italy and elsewhere, the hypothesis of possible continuous damage to these structures due to the dead and cyclic loads (wind, temperature variations, etc. has been formulated by the authors. The long term behaviour of historic masonry has also been detected by laboratory creep and cyclic tests. The results indicate that a laboratory and on site investigation together with analytical modelling are important peculiarly for tall bell-towers. The application of these procedures on the Bell-Tower of the Cathedral of Monza is here reported and discussed.

    We report a new two-photon polarization correlation experiment for realizing the Einstein-Podolsky-Rosen-Bohm (EPRB) state and for testing Bell-type inequalities. We use the pair of orthogonally-polarized light quanta generated in Type 2 parametric down conversion. Using 1 nm interference filters in front of our detectors, we observe from the output of a 0.5mm beta - BaB2O4 (BBO) crystal the EPRB correlations in coincidence counts, and measure an associated Bell inequality violation of 22 standard deviations. The quantum state of the photon pair is a polarization analog of the spin-1/2 singlet state.

    2011-06-01

    Full Text Available Abstract Background There are a variety of treatment options for Bell's palsy. Evidence from randomized controlled trials indicates corticosteroids can be used as a proven therapy for Bell's palsy. Acupuncture is one of the most commonly used methods to treat Bell's palsy in China. Recent studies suggest that staging treatment is more suitable for Bell's palsy, according to different path-stages of this disease. The aim of this study is to compare the effects of prednisolone and staging acupuncture in the recovery of the affected facial nerve, and to verify whether prednisolone in combination with staging acupuncture is more effective than prednisolone alone for Bell's palsy in a large number of patients. Methods/Design In this article, we report the design and protocol of a large sample multi-center randomized controlled trial to treat Bell's palsy with prednisolone and/or acupuncture. In total, 1200 patients aged 18 to 75 years within 72 h of onset of acute, unilateral, peripheral facial palsy will be assessed. There are six treatment groups, with four treated according to different path-stages and two not. These patients are randomly assigned to be in one of the following six treatment groups, i.e. 1 placebo prednisolone group, 2 prednisolone group, 3 placebo prednisolone plus acute stage acupuncture group, 4 prednisolone plus acute stage acupuncture group, 5 placebo prednisolone plus resting stage acupuncture group, 6 prednisolone plus resting stage acupuncture group. The primary outcome is the time to complete recovery of facial function, assessed by Sunnybrook system and House-Brackmann scale. The secondary outcomes include the incidence of ipsilateral pain in the early stage of palsy (and the duration of this pain, the proportion of patients with severe pain, the occurrence of synkinesis, facial spasm or contracture, and the severity of residual facial symptoms during the study period. Discussion The result of this trial will assess the

    Nonclassical states of light field have been exploited to provide marvellous results in quantum information science. Usefulness of nonclassical states in quantum information science depends on whether a physical parameter as a signal is continuous or discrete. Here we present an investigation of the potential of quasi Bell states of entangled coherent states in quantum reading of the classical digital memory which was pioneered by Pirandola (Phys.Rev.Lett.,106,090504,2011). This is a typical example of discrimination for discrete quantum parameters. We show that the quasi Bell state gives the error free performance in the quantum reading that cannot be obtained by any classical state.

    A cooperative ight test by NASA, Bell Helicopter and the U.S. Army to characterize the steady state acoustics and measure the maneuver noise of a Bell Helicopter 430 aircraft was accomplished. The test occurred during June/July 2011 at Eglin Air Force Base, Florida. This test gathered a total of 410 test points over 10 test days and compiled an extensive database of dynamic maneuver measurements. Three microphone arrays with up to 31 microphon. es in each were used to acquire acoustic data. Aircraft data included Differential Global Positioning System, aircraft state and rotor state information. This paper provides an overview of the test and documents the data acquired.

    Huanglongbing (HLB) is currently considered the most destructive disease of citrus. Since its spread to the Americas, HLB has killed millions of trees and caused a sharp decline in production in many citrus growing regions. With the continuous spread of HLB disease in Florida and worldwide, there is an urgent need for the development of commercial citrus cultivars with a strong tolerance to HLB. Interestingly, field observations showed that some of the recently released mandarin hybrids such as 'Sugar Belle' were tolerant to HLB. In this study, we investigated the volatile and non-volatile metabolites of greenhouse-grown 'Sugar Belle' mandarin and four of its ancestors in order to understand why 'Sugar Belle' mandarin is relatively tolerant to HLB. Leaf volatiles were directly extracted with hexane and analyzed using gas chromatography-mass spectrometry (GC-MS). Leaf polar metabolites were extracted with a mixture of methanol:water (1:1, v/v), derivatized to their trimethylsilyl ethers, and analyzed using GC-MS. Forty-seven volatile compounds and forty-two polar metabolites were detected in 'Sugar Belle' mandarin leaves and its ancestors. 'Sugar Belle' was high in several volatiles such as α-thujene, para-cymene, γ-terpinene, thymol, β-elemene, and (E)-β-caryophyllene. Some of these volatiles, especially thymol, β-elemene, and (E)-β-caryophyllene are known for their anti-microbial activity. In addition, 'Sugar Belle' mandarin was the highest in synephrine, benzoic acid, ferulic acid, caffeic acid, chiro-inositol, fructose, glucose, threonic acid, saccharic acid, and galactaric acid, and the second in threonine, malic acid, and myo-inositol compared to the ancestors. Phenolic compounds such as benzoic, ferulic, and caffeic acids may act as antibacterial agents, whereas others like sugar alcohols may protect 'Sugar Belle' mandarin from stress during pathogen attack. The tolerance of 'Sugar Belle' and other newly released mandarin hybrids should be further

    Full Text Available Twenty-five years after the publication of the famous Daniel Bell's book The Coming of Post-industrial Society, new edition of the book was published with a foreword written by the author named 'The Axial Age of Technology'. In the foreword Bell clarifies his theses and predictions in relation to the changes that have taken place in meantime in contemporary society, as well as regarding to the critics of his theory. The aim of the paper is to show how Bell explains social development in the second half of the twentieth century as well as the main characteristics of that society of 'transitory nature' in which we live. Bell's starting theoretical and methodological point of view are discussed as well as the explanation of transition from industrial to post-industrial society and the possibilities of development of the third world societies. The main characteristic of post-industrial society, according to Bell, is the codification of theoretical knowledge and the new relation between science and technology. Main post-industrial developments are: the rise of service sector, occupational changes, changes in professions and education, growing role of financial and human capital, new forms of infrastructure and knowledge theory of value. New form of society is emerging, with changes in stratification system, economy, organization and consumption. Bell doesn't plead for a holistic view of society. Instead, he considers society as comprising three realms that can change in different ways, so historical change is not unified. Major instrument of historical change is technology, it poses problems for culture and political system but it doesn't determine them. He rejects the accusations of technological determinism because technology often operates in context it doesn't make. Daniel Bell was one of the first authors who stated that modern society had been fundamentally changing. His aim was to make a conceptual framework for the comprehensive explanation

  18. On the dynamics of StemBells: Microbubble-conjugated stem cells for ultrasound-controlled delivery

    The use of stem cells for regenerative tissue repair is promising but hampered by the low number of cells delivered to the site of injury. To increase the delivery, we propose a technique in which stem cells are linked to functionalized microbubbles, creating echogenic complex dubbed StemBells. StemBells are highly susceptible to acoustic radiation force which can be employed after injection to push the StemBells locally to the treatment site. To optimally benefit from the delivery technique, a thorough characterization of the dynamics of StemBells during ultrasound exposure is needed. Using high-speed optical imaging, we study the dynamics of StemBells as a function of the applied frequency from which resonance curves were constructed. A theoretical model, based on a modified Rayleigh-Plesset type equation, captured the experimental resonance characteristics and radial dynamics in detail.

    The Belle II experiment will start physics data taking in 2016 at the SuperKEKB factory to search for new physics beyond the Standard Model from flavor physics channels. The Belle II data acquisition (DAQ) system consists of a large number of subsystems to handle the high trigger rate and huge data bandwidth, where each subsystem can be considered as a network-accessible component distributed in a control network. A software control and monitoring system for the Belle II experiment was newly developed to manage the data flow and the subsystems. A slow control system handles with the operations of the DAQ subsystems, including parameter management with relational databases while a data quality monitor system analyzes event sample in the online data flow to monitor status of the detector and data taking. Graphical user interfaces were also developed for both of the software systems. We report designs of the slow control and the DQM system and results of operation of a beam test with prototypes of the Belle detector components in the DESY test beam facility in January, 2014.

    Full Text Available Abstract Objective Incomplete recovery from facial palsy has a long-term impact on the quality of life, and medical options for the sequelae of Bell's palsy are limited. Invasive treatments and physiotherapy have been employed to relieve symptoms, but there is limited clinical evidence for their effectiveness. Acupuncture is widely used on Bell's palsy patients in East Asia, but there is insufficient evidence for its effectiveness on Bell's palsy sequelae. The objective is to evaluate the efficacy and safety of acupuncture in patients with sequelae of Bell's palsy. Method/Design This study consists of a randomized controlled trial with two parallel arms: an acupuncture group and a waitlist group. The acupuncture group will receive acupuncture treatment three times per week for a total of 24 sessions over 8 weeks. Participants in the waitlist group will not receive any acupuncture treatments during this 8 week period, but they will participate in the evaluations of symptoms at the start of the study, at 5 weeks and at 8 weeks after randomization, at which point the same treatment as the acupuncture group will be provided. The primary outcome will be analyzed by the change in the Facial Disability Index (FDI from baseline to week eight. The secondary outcome measures will include FDI from baseline to week five, House-Brackmann Grade, lip mobility, and stiffness scales.

    WebDav and HTTP are becoming popular protocols for data access in the High Energy Physics community. The most used Grid and Cloud storage solutions provide such kind of interfaces, in this scenario tuning and performance evaluation became crucial aspects to promote the adoption of these protocols within the Belle II community. In this work, we present the results of a large-scale test activity, made with the goal to evaluate performances and reliability of the WebDav protocol, and study a possible adoption for the user analysis. More specifically, we considered a pilot infrastructure composed by a set of storage elements configured with the WebDav interface, hosted at the Belle II sites. The performance tests include a comparison with xrootd and gridftp. As reference tests we used a set of analysis jobs running under the Belle II software framework, accessing the input data with the ROOT I/O library, in order to simulate as much as possible a realistic user activity. The final analysis shows the possibility to achieve promising performances with WebDav on different storage systems, and gives an interesting feedback, for Belle II community and for other high energy physics experiments.

    We present Hubble Space Telescope F606W-band imaging observations of 21 galaxy-Ly α emitter lens candidates in the Baryon Oscillation Spectroscopic Survey Emission-Line Lens Survey (BELLS) for the GALaxy-Ly α EmitteR sYstems (BELLS GALLERY) survey. Seventeen systems are confirmed to be definite lenses with unambiguous evidence of multiple imaging. The lenses are primarily massive early-type galaxies (ETGs) at redshifts of approximately 0.55, while the lensed sources are Ly α emitters (LAEs) at redshifts from two to three. Although most of the lens systems are well fit by smooth lens models consisting of singular isothermal ellipsoids in an external shear field, a thorough exploration of dark substructures in the lens galaxies is required. The Einstein radii of the BELLS GALLERY lenses are, on average, 60% larger than those of the BELLS lenses because of the much higher source redshifts. This will allow for a detailed investigation of the radius evolution of the mass profile in ETGs. With the aid of the average ∼13× lensing magnification, the LAEs are frequently resolved into individual star-forming knots with a wide range of properties. They have characteristic sizes from less than 100 pc to several kiloparsecs, rest-frame far-UV apparent AB magnitudes from 29.6 to 24.2, and typical projected separations of 500 pc to 2 kpc.

    We propose a quantum secure direct communication protocol via a collective noise channel, exploiting polarization-entangled Bell states and the nondemolition parity analysis based on weak cross-Kerr nonlinearities. The participant Bob, who will receive the secret information, sends one of two photons in a polarization-entangled Bell state exploiting the transmission circuit against the collective noise to the participant Alice, who will send the secret information, by the means of photon block transmission. If the first security check employing the nondemolition parity analysis is passed, the task of securely distributing the quantum channel is fulfilled. Encoding secret information on the photons sent from Bob by performing single-photon unitary transformation operations, Alice resends these photons to Bob through the transmission circuit against the collective noise. Exploiting the nondemolition parity analysis to distinguish Bell states, Bob can obtain the secret information from Alice after the second security check is passed, and the resulting Bell states can be applied to other tasks of quantum information processing. Under the condition of the secure quantum channel being confirmed, the photons that are utilized in the role of the security check can be applied to the function of secure direct communication, thus enhancing the efficiency of transmitting secret information and saving a lot of resources.

    The Belle II detector at the Super KEKB e+e‑collider plans to take first collision data in 2018. The monetary and CPU time costs associated with storing and processing the data mean that it is crucial for the detector components at Belle II to be calibrated quickly and accurately. A fast and accurate calibration system would allow the high level trigger to increase the efficiency of event selection, and can give users analysis-quality reconstruction promptly. A flexible framework to automate the fast production of calibration constants is being developed in the Belle II Analysis Software Framework (basf2). Detector experts only need to create two components from C++ base classes in order to use the automation system. The first collects data from Belle II event data files and outputs much smaller files to pass to the second component. This runs the main calibration algorithm to produce calibration constants ready for upload into the conditions database. A Python framework coordinates the input files, order of processing, and submission of jobs. Splitting the operation into collection and algorithm processing stages allows the framework to optionally parallelize the collection stage on a batch system.

    Bell's palsy is a kind of facial nerve diseases with a high incidence, and the patients who get the disease the first time predominate in the patients who suffer mildly or moderately. The aim of the present study is to explore a novel assessment for Bell's palsy objectively and noninvasively based on infrared thermal image. As the acupoints on the face are approximately bilateral symmetric, the acupoints on the affected side were chosen as the experimental group, while the same ones on the other side as the control group. Their infrared thermal radiations were researched separately and the results were as follows: on acute stage, the differences of infrared thermal radiation intensity of the same points were significant between the healthy and affected sides, indicating significant temperature difference (over 0.3 degrees C). The acupoints on the affected side with its surrounding tissue formed an irregular abnormal region on the infrared thermal image. Its pseudocolor was obviously different from that of the healthy side. At the same time, the more serious the Bell's palsy, the more evident the temperature differences of the same acupoints on bilateral sides. It was positive correlation (r=0.676, r=0.498, r=0.506, r=0.545, r=0.518, all Pinfrared thermal image could be used to objectively assess the severity of Bell' palsy.

    A Pilot Demonstration is being conducted to determine whether micellar-polymer flooding is an economically feasible technique for enhanced oil recovery from the Muddy Sand Unit ''A'' Reservoir of the Bell Creek Field, Powder River and Carter Counties, Montana. During the first year of this project extensive reservoir studies, site and pattern selection, design and selection of an optimal micellar-polymer system, water flood history matching and preliminary process simulations by numerical models, and development of pilot injection and production wells were completed. The major effort during the first contract year was the design for the Bell Creek pilot of two optimal micellar-polymer processes--one oil-external and one water-external; and the concomitant development of a Selection Methodology by which to decide upon the more suitable process by means of a standard set of laboratory experiments and numerical simulations. This effort was completed. The oil-external design was selected for Bell Creek application based upon its superior performance in the standard test series and simulations. The advantages of the Bell Creek oil-external design appear to be better recovery performance, mobility control, and protection against divalent ions. 30 tables, 41 figs.

    Full Text Available In Latin-America, there are countries with high production levels of green bell peppers, which requires of new strategies of conservation for their international trade. Traditional techniques of preservations do not guarantee to prolong the shelf life of these kinds of fruits, for this reason, in the present study, the Influence of different edible coating formulations on shelf-life quality of green bell peppers was studied. Three different biopolymers (pectin, arabic, and xanthan gums were evaluated in mixtures with candelilla wax as hydrophobic phase, jojoba oil as plasticizer and a crude extract of polyphenols as source of bioactive compounds. Green bell peppers were immersion-treated and then stored at room temperature. Response variables were: weight loss, color, appearance, pH, total soluble solids and firmness changes which were kinetically determined. All peppers treated with edible-coating showed a significant difference (Tukey, p≤0.05 in weight loss compared to control treatment (without edible coating, while a lower level of deterioration was observed in fruits treated with edible coating formulated with arabic gum, but appearance remained similar among fruits treated with different edible coatings. Use of mixtures of biopolymers, candelilla wax, jojoba oil and polyphenols to develop edible and functionalized coatings significantly extended shelf life of green bell pepper.

    We investigate the quantum correlations including quantum discord and entanglement under the amplitude damping channel. Our analysis results indicate that although the entanglement of initial state is degraded due to decoherence, the distribution trend of entanglement is not to be affected. Moreover, we find that the survival time for entanglement is much longer than for the Bell inequality violation, i.e., as time goes on the Bell inequality violation of final state may be not satisfied while the final state still remains entangled. Especially, although quantum entanglement and quantum discord all decrease under the amplitude damping channel, quantum discord (QD) is reduced significantly slower than entanglement. Therefore, the quantum discord is more robust against amplitude damping in comparison to entanglement measures. Furthermore, we also find that there are mixed states having quantum discord higher than that for pure states for a given degree of Bell's inequality violation. This means that the manipulation of nonclassical correlations via a pure state can result in a larger loss of quantum discord than that via a mixed state. - Highlights: • Entanglement distribution trend is not be affected by the decoherent. • The survival time for entanglement is much longer than for the Bell inequality violation. • The quantum discord is more robust against amplitude damping in comparison entanglement measures.

  7. A local realistic model of quantum information systems explaining the four Bell states

    Science.gov (United States)

    Boyd, Jeffrey

    Can quantum computers and other information systems (like cryptography) be explained by local realism? The overwhelming consensus is NO. Thirty years of Bell test experiments proved Einstein, Podolsky and Rosen (EPR) wrong. Unknown to most physicists a new form of local realism has arisen, drastically different than EPR. The Theory of Elementary Waves (TEW) proposes that two entangled particles are both following the same elementary bi-ray. The same Bell test experiments that invalidate EPR, validate TEW. What is an elementary bi-ray? In TEW waves and particles usually travel in opposite directions. In entanglement experiments the picture is more complex. A bi-ray consists of two coaxial elementary rays, moving in opposite directions. Such bi-rays can explain all four Bell states on the basis of this peculiar form of local realism. Bell theory would classify TEW as ``nonlocal,'' even though it is local and realistic. The word ``nonlocal'' needs to be discarded, since ``elementary bi-ray'' is a more accurate and fertile descriptor of the same phenomena. TEW explains entanglement swapping heralding entanglement between distant spinning electrons in NV cavities, or trapped ions. The question is: So what? Would anything in quantum information science change if TEW were true? We think not.

  13. Pontine stroke presenting as isolated facial nerve palsy mimicking Bell's palsy: a case report

    2011-07-01

    Full Text Available Abstract Introduction Isolated facial nerve palsy usually manifests as Bell's palsy. Lacunar infarct involving the lower pons is a rare cause of solitary infranuclear facial paralysis. The present unusual case is one in which the patient appeared to have Bell's palsy but turned out to have a pontine infarct. Case presentation A 47-year-old Asian Indian man with a medical history of hypertension presented to our institution with nausea, vomiting, generalized weakness, facial droop, and slurred speech of 14 hours' duration. His physical examination revealed that he was conscious, lethargic, and had mildly slurred speech. His blood pressure was 216/142 mmHg. His neurologic examination showed that he had loss of left-sided forehead creases, inability to close his left eye, left facial muscle weakness, rightward deviation of the angle of the mouth on smiling, and loss of the left nasolabial fold. Afferent corneal reflexes were present bilaterally. MRI of the head was initially read as negative for acute stroke. Bell's palsy appeared less likely because of the acuity of his presentation, encephalopathy-like imaging, and hypertension. The MRI was re-evaluated with a neurologist's assistance, which revealed a tiny 4 mm infarct involving the left dorsal aspect of the pons. The final diagnosis was isolated facial nerve palsy due to lacunar infarct of dorsal pons and hypertensive encephalopathy. Conclusion The facial nerve has a predominant motor component which supplies all muscles concerned with unilateral facial expression. Anatomic knowledge is crucial for clinical localization. Bell's palsy accounts for around 72% of facial palsies. Other causes such as tumors and pontine infarcts can also present as facial palsy. Isolated dorsal infarct presenting as isolated facial palsy is very rare. Our case emphasizes that isolated facial palsy should not always be attributed to Bell's palsy. It can be a presentation of a rare dorsal pontine infarct as observed

    Staff response to patient call bells is a communication issue that influences patient assessment of care quality and satisfaction. An ethnographic, grounded theory approach was used to examine nurses and nursing support staff perspectives about call bell use on single- versus double-patient-room units. We used the dance metaphor to describe differences in staff behaviors related to answering call bells on the 2 units in the study. Unit culture as exemplified by an enhanced call bell system and a relationship-centered leadership style were associated with a well- choreographed call bell answering process that promoted safety and patient satisfaction.

    Sweet red bell pepper is one of the best sources of ascorbic acid and carotenoids as well as phenolic compounds important in the human diet. There have been some studies showing a higher level of bioactive compounds in organic bell pepper fruits compared with conventional fruits, but not all studies have been consistent in this respect. The levels of carotenoids and phenolics are very variable and may be affected by ripeness, genotype and cultivation. The results obtained in this study showed that an organic growing system affected the level of bioactive compounds (carotenoids and polyphenols) in sweet bell pepper fruits cultivated in Poland. Organic bell pepper fruits contained significantly more dry matter, vitamin C, total carotenoids, β-carotene, α-carotene, cis-β-carotene, total phenolic acids (as well as individual gallic and chlorogenic acids) and flavonoids (quercetin D-glucoside, quercetin and kaempferol) compared with conventional fruits. The bell pepper variety also affected the level of antioxidant compounds in fruits. Organic growing increased the level of antioxidant compounds such as carotenoids, phenolic compounds and vitamin C in sweet bell pepper. The second significant factor affecting the antioxidant compound content of sweet bell pepper was variety. It would be necessary to continue this study as a long-term experiment in order to eliminate the influence of seasonality. Copyright © 2012 Society of Chemical Industry.

    Pollen from bell pepper plants cultivated in greenhouses are known to cause occupational allergic disease. A cross-sectional study among 472 bell pepper employees in 1999 estimated prevalences for sensitization to bell pepper pollen of 28% and for work-related allergic symptoms of 54%. There is scarce information on the incidence of work-related allergy and its risk factors. Aims of the present study were to estimate the cumulative incidence of work-related symptoms and sensitization to bell pepper pollen, and to determine risk factors for the onset of these symptoms and sensitization. Bell pepper employees who participated in a cross-sectional survey in 1999 were asked to take part in a follow-up study in 2007. Information on demographic characteristics, job characteristics and allergic symptoms was gathered by means of a questionnaire. Furthermore, skin tests were performed with a.o. bell pepper pollen. In total, 280 of 472 employees were available for questionnaires and in 250 employees allergy tests were performed. During the 8-year follow-up, the cumulative incidence of sensitization to bell pepper pollen was 9% and of work-related rhinitis 19%. Atopy [odds ratio (OR) 5.60] and smoking (OR 3.53) were significantly associated with development of rhinitis. The cumulative incidence of work-related asthma symptoms was 8%. Again atopy (OR 5.03) and smoking (OR 11.85) were significant risk factors. Cumulative incidences for sensitization to bell pepper pollen, work-related rhinitis and asthma symptoms were 9%, 19% and 8%, respectively. Atopy and smoking are risk factors for developing work-related symptoms among workers in bell pepper horticulture. © 2010 John Wiley & Sons A/S.

  17. Semileptonic decays of strange beauty mesons at Belle

    2015-06-19

    Semileptonic decays of b-flavoured mesons are an important tool for the determination of the CKM matrix element vertical stroke V{sub cb} vertical stroke. In this thesis, measurements of semileptonic B{sub s} meson decays are presented. They provide complementary information to the precision measurements of B meson decays and serve as a test of QCD-calculations predicting SU(3) flavour symmetry for the partial decay widths and form factors. The semi-inclusive and inclusive analyses of semileptonic B{sub s} decays are based on the 121.4 fb{sup -1} dataset collected by the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider in Tsukuba, Japan. The sample recorded at a centre-of-mass energy √(s)=10.86 GeV, which corresponds to the Y(5S) resonance, contains (7.1±1.3) million B{sub s} pair events. To measure the semi-inclusive B{sub s} → D{sub s}Xlν and B{sub s} → D{sub s}{sup *}Xlν branching fractions, D{sub s} and D{sub s}{sup *} candidates are reconstructed and are paired with an oppositely charged lepton, l{sup +}=e{sup +},μ{sup +}. The yields of correctly reconstructed D{sub s} and D{sub s}{sup *} mesons are determined by fits to their respective invariant mass distributions. The signal yield and the yields of the remaining backgrounds are extracted using kinematic distributions of the reconstructed decay products and the constraint from the known initial state of the e{sup +}e{sup -} collision. The measured branching fractions are: B(B{sub s} → D{sub s}Xlν)=(8.2±0.2(stat)±0.6(syst)±1.4(ext)) % and B(B{sub s} → D{sub s}{sup *}lν)=(5.4±0.4(stat)±0.4(syst)±0.9 (ext)) %, where the first two uncertainties are the statistical and systematic uncertainties of the measurement and the last uncertainty is due to external parameters. Making an assumption about the B{sub s} → D{sub s}Xlν branching fraction, the measurement of the B{sub s} → D{sub s}Xlν yield is also used to obtain the current best estimate of the B{sub s} pair

    A protocol for the quantum secure multi-party summation based on two-particle Bell states is proposed. In this protocol, two-particle Bell states are used as private information carriers. Without using the entangled character of Bell states, we also use Pauli matrices operations to encode information and Hadamard matrix to extract information. The proposed protocol can also resist various attacks and overcomes the problem of information leakage with acceptable efficiency. In theory, our protocol can be used to build complex secure protocols for other multiparty computations and also lots of other important applications in distributed networks.

    Full Text Available Com o advento dos testes eletrofisiológicos, a avaliação clínica parece ter perdido interesse na paralisia de Bell. A eletroneuronografia (ENoG associada ao estadiamento clínico da doença é o método mais freqüentemente utilizado para mensurar o prognóstico da paralisia de Bell. Entretanto, a ENoG constitui-se em um teste eletrofisiológico ainda não universalmente disponível, especialmente nos serviços de emergência.

FORMA DE ESTUDO: coorte historica. MATERIAL E MÉTODO: Estudo coorte retrospectivo, analisando 1521 casos de paralisia de Bell, correlacionando-se os dados clínicos sexo, idade, lado da paralisia, modo de instalação, sintomas prévios, sintomas associados e os resultados do teste de estimulação elétrica mínima (Hilger, com a evolução da paralisia após 6 meses. RESULTADO: O estudo desses dados indicou que pacientes acima de 60 anos apresentaram prognóstico pior em comparação com pacientes com idade abaixo de 30 anos; o modo de instalação progressiva, a ausência de sintomas prévios, a presença de vertigem concomitante à paralisia e resposta acima de 3,5 mm no teste de Hilger estiveram relacionados com mau prognóstico. Por outro lado, a ausência de sintomas concomitantes, a diminuição do lacrimejamento e o início súbito foram relacionados com bom prognóstico. CONCLUSÃO: A análise de fatores clínicos, associada ao teste de Hilger, pode indicar o prognóstico da paralisia facial com reduzida margem de erro, sendo uma alternativa bastante interessante especialmente quando não há disponibilidade da ENoG.Electroneurography (ENoG and clinical staging are currently the methods of choice to indicate prognosis in Bell's palsy, although ENoG is an

  1. In AppreciationThe Depth and Breadth of John Bell's Physics

    Science.gov (United States)

    Jackiw, Roman; Shimony, Abner

    This essay surveys the work of John Stewart Bell, one of the great physicists of the twentieth century. Section 1 is a brief biography, tracing his career from working-class origins and undergraduate training in Belfast, Northern Ireland, to research in accelerator and nuclear physics in the British national laboratories at Harwell and Malvern, to his profound research on elementary particle physics as a member of the Theory Group at CERN and his equally profound ``hobby'' of investigating the foundations of quantum mechanics. Section 2 concerns this hobby, which began in his discontent with Bohr's and Heisenberg's analyses of the measurement process. He was attracted to the program of hidden variables interpretations, but he revolutionized the foundations of quantum mechanics by a powerful negative result: that no hidden variables theory that is ``local'' (in a clear and well-motivated sense) can agree with all the correlations predicted by quantum mechanics regarding well-separated systems. He further deepened the foundations of quantum mechanics by penetrating conceptual analyses of results concerning measurement theory of von Neumann, de Broglie and Bohm, Gleason, Jauch and Piron, Everett, and Ghirardi-Rimini-Weber. Bell's work in particle theory (Section 3) began with a proof of the CPT theorem in his doctoral dissertation, followed by investigations of the phenomenology of CP-violating experiments. At CERN Bell investigated the commutation relations in current algebras from various standpoints. The failure of current algebra combined with partially conserved current algebra to permit the experimentally observed decay of the neutral pi-meson into two photons stimulated the discovery by Bell and Jackiw of anomalous or quantal symmetry breaking, which has numerous implications for elementary particle phenomena. Other late investigations of Bell on elementary particle physics were bound states in quantum chromodynamics (in collaboration with Bertlmann) and

    We proposed a possible protocol for Bell state measurements of spin qubits in a double quantum dot (QD). Our scheme consists of Pauli spin blockade measurements and biaxial electron spin resonance. It is assumed that the two QDs here are designed so that the Lande g-factors satisfy g{sub 1} = -g{sub 2} with the use of g-factor engineering. The opposite sign of the g-factors cancel the average of the Zeeman fields on the two QDs, and enable us to swap three spin-triplet states for a spin-singlet state sequentially. We showed that it is possible to implement the full Bell state measurement by the sequential spin-to-charge conversions in the QD-based spin qubits.

    The Belle-II VerteX Detector (VXD) has been designed to improve the performances with respect to Belle and to cope with an unprecedented luminosity of 8 ×1035cm-2s-1 achievable by the SuperKEKB. Special care is needed to monitor both the radiation dose accumulated throughout the life of the experiment and the instantaneous radiation rate, in order to be able to promptly react to sudden spikes for the purpose of protecting the detectors. A radiation monitoring and beam abort system based on single-crystal diamond sensors is now under an active development for the VXD. The sensors will be placed in several key positions in the vicinity of the interaction region. The severe space limitations require a challenging remote readout of the sensors.

    A scheme for distributed quantum measurement that allows nondestructive or indirect Bell measurement was proposed by Gupta et al [1]. In the present work, Gupta et al.'s scheme is experimentally realized using the five-qubit super-conductivity-based quantum computer, which has been recently placed in cloud by IBM Corporation. The experiment confirmed that the Bell state can be constructed and measured in a nondestructive manner with a reasonably high fidelity. A comparison of the outcomes of this study and the results obtained earlier in an NMR-based experiment (Samal et al. (2010) [10]) has also been performed. The study indicates that to make a scalable SQUID-based quantum computer, errors introduced by the gates (in the present technology) have to be reduced considerably.

    In order to achieve excellent single point resolution and to keep multiple scattering at a minimum with low material budget, DEPFET sensors were chosen as inner two layers of the VXD (Vertex Detector) for the Belle II experiment. DEPFET sensors also offer a low power consumption and a high signal to noise ratio, even for thin sensors. The Electrical Multi-Chip Module (EMCM) was designed in the interest of studying especially the metal layer interconnectivity for the steering and regulation of the DEPFET matrix of the detectors for Belle II. The main goal of this study of the metal system is to get insights on the feasibility and reliability of the technology and collect information on its production yield. This study is done on wafer level. Specially designed test structures and testing strategies, developed to be able to identify all possible causes of reduction of the yield, are presented. Finally results obtained from the optimized metallization technology are shown.

    DEPFET pixel detectors offer excellent signal to noise ratio, resolution and low power consumption with a low material budget. They will be used at Belle II and are a candidate for an ILC vertex detector. The pixels are integrated in a monolithic piece of silicon which also acts as PCB providing the signal and control routings for the ASICs on top. The first prototype DEPFET sensor modules for Belle II have been produced. The modules have 192000 pixels and are equipped with SMD components and three different kinds of ASICs to control and readout the pixels. The entire readout chain has to be studied; the metal layer interconnectivity and routings need to be verified. The modules are fully characterized, and the operation voltages and control sequences of the ASICs are investigated. An overview of the DEPFET concept and first characterization results is presented.

  10. Bell's Theorem and Einstein's `Spooky Actions' from a Simple Thought Experiment

    2010-02-01

    In 1964 John Bell proved a theorem2 allowing the experimental test of whether what Einstein derided as "spooky actions at a distance" actually exist. We will see that they do. Bell's theorem can be displayed with a simple, nonmathematical thought experiment suitable for a physics course at any level. And a simple, semi-classical derivation of the quantum theory result can be given for physics students. These entanglement phenomena are today applied in industrial laboratories and are increasingly discussed in the popular literature. Unfortunately, they are also misappropriated by the purveyors of pseudoscience, something physicists have a responsibility to address.3 Students can be intrigued by the quantum strangeness physics has encountered at a boundary of our discipline.

    The z-vertex trigger is part of the first level track trigger in the Belle II experiment. Its task is the rejection of tracks not coming from the interaction region, suppressing a large part of the machine background. Therefore the z-vertex trigger allows to relax other track trigger conditions and thus strongly increases the efficiency for channels with low track multiplicity (e.g. tau pair production). The track trigger works in several steps, first combining hits to track segments, followed by a 2D track finding in the transverse plane and finally the 3D reconstruction. Our method employs neural networks to estimate the z-vertex without explicit track reconstruction. For the first real test with cosmic rays special neural networks have been prepared. Although the track shape in the cosmic test is different than in the Belle II experiment, the neural networks require only a retraining with an appropriate data set to adapt to the new geometry.

    The Super-KEKB accelerator at the KEK high energy research center in Tsukuba in Japan will provide a 40 times higher luminosity. To cope with this high luminosity the Belle detector is improved to Belle II, which includes the integration of a two layer DEPFET pixel detector (PXD) resulting in a higher vertex resolution. The task of the read-out electronics is to process the high data rate of the PXD. To fulfill these requirements three different types of ASICs were designed. The foremost of them called Drain Current Digitizer (DCD) converts the drain currents of the DEPFET pixel sensors into digital code. Since the PXD will be equipped with 160 DCDs automatic testing of the chips is needed. Analog to digital transfer curves are an appropriate tool for error recognition and optimization of the digitization process within the DCD. An overview of measurements and optimization strategies is presented.

    2014-10-03

    It is well known that an unambiguous discrimination of the four optically encoded Bell states is possible with a probability of 50% at best, when using static, passive linear optics and arbitrarily many vacuum-mode ancillae. By adding unentangled single-photon ancillae, we are able to surpass this limit and reach a success probability of at least 75%. We discuss the error robustness of the proposed scheme and a generalization to reach a success probability arbitrarily close to 100%.

    2011-01-01

    Full Text Available Aim: Pectus Excavatum (PE is the most common chest wall malformation, and one of the most frequent major congenital anomalies. Surgical repair of PE in childhood is a well-established procedure. Previously used operative techniques to correct PE were largely based on the Ravitch technique. Today, the minimally invasive repair (MIRPE by Nuss is well established. Conservative treatment with the vacuum bell to elevate the funnel in patients with PE, represents a potential alternative. Material and Methods:  A suction cup is used to create a vacuum at the anterior chest wall. 3 different sizes of vacuum bell exist which are selected according to the individual patients age. When creating the vacuum, the lift of the sternum is obvious and remains for a different time period. The device should be used for a minimum of 30 minutes (2/day, and may be used up to a maximum of several hours daily. Results; 93 patients (77 males, 16 females, aged 3 to 61 years (median 17.8 years used the vacuum bell for 1 to maximum 24 months. Computed tomographic scans showed that the device lifted the sternum and ribs immediately. In addition, this was confirmed thoracoscopically during the MIRPE procedure. After 18 months in average, the sternum was lifted to a normal level in 9 patients. Relevant side effects were not noted. Conclusions: The vacuum bell has proved to be an alternative therapeutic option in selected patients with PE. The initial results proved to be dramatic, but longterm results are so far lacking, and further evaluation and follow-up studies are necessary.

    Neurologists, like physicians in several other medical specialties, can lay claim to Sherlock Holmes as one of their own. This assertion is validated by the number of neurologic conditions, such as seizures, stroke, syncope, encephalopathies, and head trauma, that are mentioned in the stories and novels. In addition, the article reviews the powers of observation and the deductive approach utilized by Conan Doyle and Joseph Bell, the models for Sherlock Holmes, and how these skills can be applied to medical problems.

    2012-05-15

    The effect of inlet radius and bell mouth radius on flow rate of centrifugal blower were numerically simulated using a commercial CFD program, FLUENT. In this research, a total of eight numerical models were prepared by combining different values of bell mouth radii and inlet radii (the cross section of bell mouth was chosen as a circular arc in this research). The frozen rotor method combined with a realizable k-epsilon turbulence model and non-equilibrium wall function was used to simulate the three-dimensional flow inside the centrifugal blowers. The inlet radius was then revealed to have significant impact on flow rate with the maximum difference between analyzed models was about 4.5% while the bell mouth radius had about 3% impact on flow rate. Parallel experiments were carried out to confirm the results of CFD analysis. The CFD results were thereafter validated owning to the good agreement between CFD results and the parallel experiment results. In addition to performance analysis, noise experiments were carried out to analyze the dependence of sound quality on inlet radius and bell mouth radius with different flow rate. The noise experiment results showed that the loudness and sharpness value of different models were quite similar, which mean the inlet radius and the bell mouth radius didn't have a clear impact on sound quality of centrifugal blower.

    Zaidi, Hussain A; van Loock, Peter

    2013-06-28

    We show that optically encoded two-qubit Bell states can be unambiguously discriminated with a success probability of more than 50% in both single-rail and dual-rail encodings by using active linear-optical resources that include Gaussian squeezing operations. These results are in contrast to the well-known upper bound of 50% for unambiguous discrimination of dual-rail Bell states using passive, static linear optics and arbitrarily many vacuum modes. We present experimentally feasible schemes that improve the success probability to 64.3% in dual-rail and to 62.5% in single-rail for a uniform random distribution of Bell states. Conceptually, this demonstrates that neither interactions that induce nonlinear mode transformations (such as Kerr interactions) nor auxiliary entangled photons are required to go beyond the one-half limit. We discuss the optimality of our single-rail scheme and talk about an application of our dual-rail scheme in quantum communication.

    2017-01-01

    PURPOSE: The purpose of the study was to evaluate the efficacy of silicone rods as frontalis sling for correction of ptosis associated with poor Bell's phenomenon in specific situations. MATERIALS AND METHODS: A retrospective interventional case series of 25 eyes of 19 patients who underwent frontalis suspension surgery with silicone rods for ptosis correction from May 2006 to April 2011, was performed. Inclusion criteria included severe ptosis with poor Bell's phenomenon. Patient evaluation included clinical history and other relevant parameters of ptosis measurement. Final outcome measurements included postoperative lid height, lagophthalmos, complications, need for reoperation, and patient satisfaction. RESULTS: Mean age at presentation was 25.72 ± 2.2 years. The sex ratio of male: female was 1.11. The causes of ptosis included chronic progressive external ophthalmoplegia (CPEO) in 11 eyes (44%), oculopharyngeal dystrophy in 2 (8%), third cranial nerve palsy in 7 (28%), traumatic in three eyes (12%), and iatrogenic postoperative ptosis (after orbital tumor excision) in two eyes (8%). The postoperative palpebral fissure height and margin reflex distance improved significantly (P = 0.0001). Extrusion of the sling and granuloma formation occurred in two eyes each, and these patients had to undergo sling removal. One patient developed mild exposure keratopathy and was managed conservatively. CONCLUSION: Silicone is an effective material for use in frontalis suspension in the management of severe ptosis with poor Bell's phenomenon. The elastic nature of silicone rod makes it an ideal suspensory material for patients with CPEO or third nerve palsy. PMID:29034153

    Recent advances in Bell's palsy (BP) were reviewed to assess the current trends in its management and prognosis. We retrieved the literature on BP using the Cochrane Database of Systematic Reviews, PubMed, and Google Scholar. Key words and phrases used during the search included 'Bell's palsy', 'Bell's phenomenon', 'facial palsy', and 'idiopathic facial paralysis'. Emphasis was placed on articles and randomized controlled trails (RCTs) published within the last 5 years. BP is currently considered the leading disorder affecting the facial nerve. The literature is replete with theories of its etiology, but the reactivation of herpes simplex virus isoform 1 (HSV-1) and/or herpes zoster virus (HZV) from the geniculate ganglia is now the most strongly suspected cause. Despite the advancements in neuroimaging techniques, the diagnosis of BP remains one of exclusion. In addition, most patients with BP recover spontaneously within 3 weeks. Corticosteroids are currently the drug of choice when medical therapy is needed. Antivirals, in contrast, are not superior to placebo according to most reliable studies. At the time of publication, there is no consensus as to the benefit of acupuncture or surgical decompression of the facial nerve. Long-term therapeutic agents and adjuvant medications for BP are necessary due to recurrence and intractable cases. In the future, large RCTs will be required to determine whether BP is associated with an increased risk of stroke.

    An upgrade of the existing Japanese flavour factory (KEK, Tsukuba) is foreseen by 2014. The new machine (SuperKEKB) will deliver an instantaneous luminosity 40 times higher than the current machine. To exploit the huge number of events that are expected, the detector (Belle) has to be also updated. To make the high precision measurements needed for the reconstruction of the B meson decay vertices in such a harsh environment, the innermost subdetector of the new experiment, Belle II, will equipped with highly pixelated DEPFET sensors. With the increased luminosity, not only higher number of physics events will be created, but also much larger background levels are expected. Under these conditions, with expected doses of up to 1 Mrad (10 kGy) per year, the radiation damage of the DEPFET sensors is an issue that has to be deeply investigated. In addition, a safe environment has to be ensured before the installation of the DEPFET vertex detector. In order to study the conditions of the surrounding volume close to the beam pipe under different configurations of the accelerator, a detector able to measure doses and background sources (BEAST II) will be operated before the final Belle II experiment, until a stable beam configuration is found. In this talk, the performance of DEPFET sensors irradiated with different dose levels and the detector concepts for the BEAST II experiment is presented.

    To examine the link between corn agriculture and the observed decline of the endangered southern bell frog (SBF), the effects of two corn crop pesticides on larval growth and development were investigated. Tadpoles were exposed to terbufos sulfone (10 {mu}g/L), a major breakdown product of the insecticide terbufos, and the herbicide atrazine (25 {mu}g/L) individually and as a mixture until the completion of metamorphosis. Atrazine did not interact synergistically with terbufos sulfone or result in significant effects on growth and development alone, although there was some indication of accelerated metamorphosis in the pilot study. Terbufos sulfone alone and as a mixture (terbufos/atrazine) significantly slowed larval development and ultimately delayed metamorphosis. The observed developmental effects from an environmentally relevant concentration of terbufos sulfone indicates a risk posed by this persistent degradation product to the endangered SBF, which breeds and develops in the rice bays adjacent to corn fields treated with pesticides. - Highlights: > The effect of terbufos sulfone and atrazine on larval growth and development was investigated. > Terbufos sulfone alone significantly slowed development and delayed metamorphosis of tadpoles. > Atrazine had no observable effects alone nor did it interact synergistically with terbufos sulfone. > The developmental effects indicates a risk to endangered southern bell frogs in the irrigation area. > The results highlight the toxicological importance of some pesticide breakdown products. - A breakdown product of the insecticide terbufos retards development and delays metamorphosis of southern bell frog tadpoles.

  11. Narcissism, Abjection and the Reader(e of Simone de Beauvoir's Les Belles Images

    Full Text Available Discussions of Simone de Beauvoir's last novel, Les Belles Images (1966, tend to be in the mode of apology. The characters are shallow—runs the typical claim—the plot (essentially, Laurence's gradual awakening to her own "belle image" identity of feminine clichés as fulfilled wife, devoted mother, successful professional flimsy and predictable. Yet, in studying a specular dynamic of narcissism and abjection within the novel, we become aware of the discomforting ways in which our own scorn for Laurence and her world is anticipated by the text. As we attend upon the dismantling of Laurence's "belles images," we are made to witness the undoing of our own narcissism. Along the way, we acquire new understanding of an important aspect of this specular relationship: the novel's slippery use of the pronouns "I" and "she" to refer to Laurence, in an unstable grammar that has confounded critics. These pronouns and their imbrication are only too pertinent, I argue, for the reader's relationship to Laurence, and for the ways in which the reader's "I" sets itself loftily apart from Laurence's "she." Yet, in dismantling the reader's assumptions along with those of Laurence, the text offers each a new way forward, beyond the crippling confines of narcissism and abjection.

    Red bell pepper carotenoids were complexed with 2-hydroxypropyl-β-cyclodextrin (2-HPβCD) in different mass ratios (1:4, 1:6, 1:8 and 1:10) through ultrasonic homogenization in order to increase carotenoid solubility and their use as natural pigment in food. Inclusion complexes, red bell pepper extract and physical mixtures were analyzed by DSC, FT-IR, (1)H NMR and DLS. Solubility assay was performed to identify the effect of complexation on the solubility of carotenoids. From characterization assays, results showed that inclusion process occurred for all tested ratios. Results for water solubility assays demonstrated clear differences between solubility index of inclusion complexes (8.06±2.59-16.55±4.40mg/mL) and physical mixtures (3.53±1.44-7.3±1.88mg/mL), while carotenoid extract was no water soluble, as expected. These results indicated that molecular inclusion of carotenoids in 2-HPβCD was efficient to enhance their solubility in water, enabling application of red bell pepper carotenoid as natural pigment and/or bioactive substances in food.

    Full Text Available ABSTRACT The objective of the study was to evaluate the effect of different managements of fertigation and NK doses on the production of bell pepper fruit in a protected environment. The experimental design was randomized blocks in 3 x 5 factorial. The treatments were formed by the combination of three managements of fertigation (M1 - Based on the rate of absorption; M2 - Monitoring the electrical conductivity of the soil solution; M3 - Monitoring concentrations of N and K ions in the soil solution, with five doses of NK (0, 50, 100, 150 and 200% of the recommended dose and four replicates. Six samples were collected and the following variables were evaluated: number, length and diameter of fruit, pulp thickness and fruit production. Except for diameter, all variables were affected by the interaction between the studied factors. The fertigation management by monitoring and controlling the ionic concentration of the soil solution is more efficient in the production of bell pepper. The fertigation management can be performed more efficiently from the managements M2 or M3, with NK doses of 144 and 165%, respectively, of the recommended concentration for the hydroponic cultivation of bell pepper.

    To study the influence of neuro-psychological factors on the effect of acupuncture in the treatment of Bell's palsy and the overall prognosis in patients. Fifty patients with Bell's palsy were randomized into the treatment group and the control group, and they were treated with manipulated and non-manipulated acupuncture, respectively. Scorings by subjective perceptive scale of acupuncture, Cartel personality test, and Hamilton Anxiety Scale were performed and the curative effect was assessed according House-Brackmann grading standards. The total effective rate of acupuncture was 78.0% (39/50), and that of manipulated acupuncture was better than that of non-manipulated acupuncture [89.2% (25/28) vs. 63.6% (14/22), P 16PF) found that patients with personality factors of sociability, intellectuality, excitability, braveness, and independence were capable of getting "Deqi" more easily, there existed a significant correlation between personality factors and curative effect. By Hamilton Anxiety Scale scoring, 92.0% (46/50) of the patients were found being in an anxiety state, and the efficacy of treatment was negatively correlated with the degree of anxiety (r = -0.9491, P < 0.05). Neuro-psychological factors put great influence on the efficacy of treatment for Bell's palsy, multiple measures, such as drug-therapy, acupuncture, psychological intervention, rehabilitation therapy, etc., should be taken in combination for improving patients' prognosis.

    A multihop teleportation protocol in quantum communication network is introduced to teleport an arbitrary two-qubit state, between two nodes without directly sharing entanglement pairs. Quantum channels are built among neighbor nodes based on a five-qubit entangled system composed of GHZ and Bell pairs. The von Neumann measurements in all intermediate nodes and the source node are implemented, and then the measurement outcomes are sent to the destination node independently. After collecting all the measurement outcomes at the destination node, an efficient method is proposed to calculate the unitary operations for transforming the receiver's states to the state teleported. Therefore, only adopting the proper unitary operations at the destination node, the desired quantum state can be recovered perfectly. The transmission flexibility and efficiency of quantum network with composite GHZ–Bell channel are improved by transmitting measurement outcomes of all nodes in parallelism and reducing hop-by-hop teleportation delay. - Highlights: • A multihop teleportation protocol is introduced to teleport two-qubit state. • Quantum channels are built by composite of GHZ and Bell pairs. • Measurement outcomes are sent to the destination node independently. • Destination node calculates and adopts unitary operations to recover initial state.

    Quantum theory presents a strange picture of the world, offering no real account of physical properties apart from observation. Neils Bohr felt that this reflected a core truth of nature: ''There is no quantum world. There is only an abstract mathematical description.'' Among the most significant developments since Bohr's day has been the theorem of John S. Bell. It is important to consider whether Bell's analysis supports such a denial of microrealism. In this book, we evaluate the situation in terms of an early work of Erwin Schroedinger. Doing so, we see how Bell's theorem is conceptually related to the Conway and Kochen Free Will theorem and also to all the major anti-realism efforts. It is easy to show that none of these analyses imply the impossibility of objective realism. We find that Schroedinger's work leads to the derivation of a new series of theoretical proofs and potential experiments, each involving ''entanglement,'' the link between particles in some quantum systems.

    Increased consumption of fruits and vegetables is linked to health benefits but also to an increase in the number of outbreaks of foodborne illness. To determine the effectiveness of different sanitizing treatments for reducing bacterial pathogens on fresh produce, fresh cantaloupes and bell peppers were harvested and inoculated with suspensions of Salmonella Typhimurium and Escherichia coli O157:H7. The inoculated fruits were treated with water wash alone or were washed and then waxed or rinsed with 200 mg/liter hypochlorite, 10% Ca(OH)2, or 2% lactic acid solutions applied by dipping for 15 s or spraying for 15 s. Preliminary experiments with chlorine treatments indicated that spraying with a 200, 600, or 1,000 mg/liter hypochlorite solution reduced populations of both pathogens by 2.1 to 2.6 and 1.5 to 2.1 log CFU for Salmonella Typhimurium and E. coli O157:H7, respectively. In general, no differences were observed between chlorine solutions without pH adjustment (pH 9.2) and those with pH adjusted to 6.0. When different wash regimes were applied to inoculated cantaloupes or bell peppers, water wash alone produced significantly lower counts of both pathogens on bell peppers in comparison to untreated controls. However, this reduction was not observed on cantaloupes, indicating a possible surface effect. Application of 2% L-lactic acid by spray was the treatment that resulted in the lowest bacterial counts on both cantaloupes and bell peppers. This treatment did not produce any deleterious change in the sensorial characteristics of the products tested. None of the pathogens studied was able to grow during refrigerated storage (5 degrees C for cantaloupes and 10 degrees C for bell peppers), although numbers close to the detection limit of the counting method were found in randomly tested individual samples at days 14 and 28 of storage, indicating that these pathogens can survive for long periods on the produce surface. These results indicate that selected produce

    Full Text Available The present study was carried out to investigate the influence of food grade coatings on fruit quality and storage life of bell pepper cv. “Yolo Wonder” at 8±1°C with 90–95% RH for 24 days. Coating treatments were given to bell pepper fruits by dipping in aqueous solutions of gum arabic (6, 9, and 12%, Aloe vera gel (4, 5, and 6%, and cinnamon oil (0.5, 0.75, and 1%. Physicochemical characteristics as well as quality of bell pepper fruits improved in all coating treatments. Results revealed that 12% gum arabic coating exhibited significantly reduced weight loss, membrane leakage, chilling injury, and decay incidence with less increase in pH, total soluble solids, and sugar percentage, whereas appealing fruit color (L⁎, a⁎, and b⁎ along with higher values of ascorbic acid (1.84 mg/100 g, titratable acidity (0.19%, and firmness (4 N was observed in cold storage environment. Our results clearly suggested that coating of bell pepper fruits with 12% gum arabic can maintain postharvest storage quality of bell pepper fruits.

  19. Efficacy of Acupuncture for Bell's Palsy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

    Full Text Available Acupuncture has emerged as an alternative therapy for Bell's palsy in both adults and children. However, the use of acupuncture is controversial. We conducted a systematic review and meta-analysis to assess the efficacy of acupuncture for Bell's palsy. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, irrespective of any language restrictions. Randomized controlled trials comparing acupuncture with other therapies for Bell's palsy in adults or children were included. Fourteen randomized controlled trials involving 1541 individuals were included in this meta-analysis. Significant association was observed in acupuncture with a higher effective response rate for Bell's palsy (relative risk, 1.14; 95% confidence interval, 1.04-1.25; P = 0.005 but there was a heterogeneity among the studies (I2 = 87%. An assessment of the included studies revealed a high risk of bias in methodological quality. An evaluation of the incidence of complications was not available, owing to incomplete data. Acupuncture seems to be an effective therapy for Bell's palsy, but there was insufficient evidence to support the efficacy and safety of acupuncture. However, the results should be interpreted cautiously, because of the poor quality and heterogeneity of the included studies.

    Full Text Available The objective of this study is to investigate the eff ects of irradiation from light-emitting diodes (LEDs on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitted from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total flavonoids and several pigments were investigated, along with the antioxidant potential. The colour parameters (L*, a* and b* and firmness of the fruit were also determined. After 7 days of LED light irradiation, there was significantly higher total phenolic content and antioxidant potential in apple peel extracts. The irradiated fruit of tomato had significantly higher levels of total phenolic compounds, and the fruit of red bell pepper had significantly higher antioxidant potential. LED light had no effects on the colour parameters, although there was a tendency to accelerate colour development. Apple fruit irradiated with LED light was significantly less firm. Among twelve analysed pigments, significantly more β-carotene was detected in LED light-irradiated apple and bell pepper fruit, more α-tocopherol and γ-tocopherol in bell pepper fruit, and more lutein in apple peel and bell pepper fruit. The applied LED light slightly accelerated the ripening of the studied fruit, and affected the synthesis of some of the secondary metabolites.

    2011-12-01

    The Belle collaboration has been trying for 10 years to reveal the mystery of the current matter-dominated universe. However, much more statistics is required to search for New Physics through quantum loops in decays of B mesons. In order to increase the experimental sensitivity, the next generation B-factory, SuperKEKB, is planned. The design luminosity of SuperKEKB is 8 x 1035cm-2s-1 a factor 40 above KEKB's peak luminosity. At this high luminosity, the level 1 trigger of the Belle II experiment will stream events of 300 kB size at a 30 kHz rate. To reduce the data flow to a manageable level, a high-level trigger (HLT) is needed, which will be implemented using the full offline reconstruction on a large scale PC farm. There, physics level event selection is performed, reducing the event rate by ~ 10 to a few kHz. To execute the reconstruction the HLT uses the offline event processing framework basf2, which has parallel processing capabilities used for multi-core processing and PC clusters. The event data handling in the HLT is totally object oriented utilizing ROOT I/O with a new method of object passing over the UNIX socket connection. Also under consideration is the use of the HLT output as well to reduce the pixel detector event size by only saving hits associated with a track, resulting in an additional data reduction of ~ 100 for the pixel detector. In this contribution, the design and implementation of the Belle II HLT are presented together with a report of preliminary testing results.

  2. Testing Quantum Mechanics and Bell's Inequality with Cosmological Observations of Quasars

    We discuss a proposed experiment which would leverage cosmology to test quantum mechanics using astronomical observations. Specifically, we aim to close the "setting independence" or so-called "free will" loophole in experimental tests of Bell's inequality by choosing the detector settings (e.g. polarizer orientations) using real-time observations of causally disconnected cosmic sources, for example sufficiently distant quasar pairs, all while the entangled particles are still in flight. This would help close one of the most important remaining Bell test loopholes whereby an alternative theory could mimic the quantum predictions if the experimental settings choices shared even a small correlation with some local "hidden variables" due to unknown causal influences a mere few milliseconds prior to the experiment. Our "Cosmic Bell" experiment would push any such hidden variable conspiracy all the way back to the hot big bang 13.8 Gyr ago, an improvement of 20 orders of magnitude. The talk will demonstrate the real world feasibility of our experimental setup, with emphasis on the theoretical cosmology constraints needed to choose optimal sources. We thus describe general conditions for pairs of cosmological events with arbitrary redshifts and angular separations to have no shared causal pasts since the hot big bang in flat, dark energy dominated, accelerating Friedman-Lemaitre-Robertson-Walker universes like our own. While causally disjoint patches of the cosmic microwave background radiation at redshift z ~ 1090 could be used to set the detectors, z > 3.65 quasars observed at optical wavelengths are arguably the optimal candidate source pairs using present technology that meet the condition of having no shared causal past since the end of any period of inflation, 13.8 Gyr ago. Results are illustrated for our universe with causal structure animations to help visualize the intersections of past light cones for arbitrary event pairs.

    Full Text Available Bell-shaped vibratory angular rate gyro (abbreviated as BVG is a new type Coriolis vibratory gyro that was inspired by Chinese traditional clocks. The resonator fuses based on a variable thickness axisymmetric multicurved surface shell. Its characteristics can directly influence the performance of BVG. The BVG structure not only has capabilities of bearing high overload, high impact and, compared with the tuning fork, vibrating beam, shell and a comb structure, but also a higher frequency to overcome the influence of the disturbance of the exterior environment than the same sized hemispherical resonator gyroscope (HRG and the traditional cylinder vibratory gyroscope. It can be widely applied in high dynamic low precision angular rate measurement occasions. The main work is as follows: the issue mainly analyzes the structure and basic principle, and investigates the bell-shaped resonator’s mathematical model. The reasonable structural parameters are obtained from finite element analysis and an intelligent platform. Using the current solid vibration gyro theory analyzes the structural characteristics and principles of BVG. The bell-shaped resonator is simplified as a paraboloid of the revolution mechanical model, which has a fixed closed end and a free opened end. It obtains the natural frequency and vibration modes based on the theory of elasticity. The structural parameters are obtained from the orthogonal method by the research on the structural parameters of the resonator analysis. It obtains the modal analysis, stress analysis and impact analysis with the chosen parameters. Finally, using the turntable experiment verifies the gyro effect of the BVG.

    Lyme disease is caused by a tick-borne spirochaete of the Borrelia species. It is associated with facial palsy, is increasingly common in England, and may be misdiagnosed as Bell's palsy. To produce an accurate map of Lyme disease diagnosis in England and to identify patients at risk of developing associated facial nerve palsy, to enable prevention, early diagnosis, and effective treatment. Hospital episode statistics (HES) data in England from the Health and Social Care Information Centre were interrogated from April 2011 to March 2015 for International Classification of Diseases 10th revision (ICD-10) codes A69.2 (Lyme disease) and G51.0 (Bell's palsy) in isolation, and as a combination. Patients' age, sex, postcode, month of diagnosis, and socioeconomic groups as defined according to the English Indices of Deprivation (2004) were also collected. Lyme disease hospital diagnosis increased by 42% per year from 2011 to 2015 in England. Higher incidence areas, largely rural, were mapped. A trend towards socioeconomic privilege and the months of July to September was observed. Facial palsy in combination with Lyme disease is also increasing, particularly in younger patients, with a mean age of 41.7 years, compared with 59.6 years for Bell's palsy and 45.9 years for Lyme disease (P = 0.05, analysis of variance [ANOVA]). Healthcare practitioners should have a high index of suspicion for Lyme disease following travel in the areas shown, particularly in the summer months. The authors suggest that patients presenting with facial palsy should be tested for Lyme disease. © British Journal of General Practice 2017.

    The Bell Detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider performed extremely well, logging an integrated luminosity an order of magnitude higher than the design baseline. With this inverse attobarn of integrated luminosity, time-dependent CP-violation inn the 3rd generation beauty quarks was firmly established, and is now a precision measurement. Going beyond this to explore if the Kobayashi-Maskawa mechanism is the only contributor to quark-mixing, and to interrogate the flavor sector for non-standard model enhancements, requires a detector and accelerator capable of topping this world-record luminosity by more than an order of magnitude. The Belle II detector at the upgraded Super-KEKB accelerator has been designed to meet this highly ambitious goal of operating at a luminosity approaching 10{sup 36} cm{sup -2} s{sup -1}. Such higher event rates and backgrounds require upgrade of essentially all detector subsystems, as well as their readout. Comparing the Belle composite (threshold Aerogel + Time of Flight) particle identification (PID) system with the DIRC employed by BaBar, quartz radiator internal Cherenkov photon detection proved to have higher kaon efficiency and lower pion fake rates. However, because the detector structure and CsI calorimeter will be retained, an improved barrel PID must fit within a very narrow envelope, as indicated in Figure 1. To effectively utilize this space, a more compact detector concept based on the same quartz radiators, but primarily using photon arrival time was proposed. This Time Of Propagation (TOP) counter was studied in a number of earlier prototype tests. Key to the necessary 10's of picosecond single-photon timing has been the development of the so-called SL-10 Micro-Channel Plate Photo-Multiplier Tube (MCP-PMT), which has demonstrated sub-40 ps single photon Transit Time Spread TTS. Further simulation study of this detector concept indicated that a focusing mirror in the forward direction, as well

    For a reliable implementation of quantum teleportation, a near-deterministic (close to 100%) discrimination of all four Bell states of entangled qubits is required. One can carry it out with linear optical elements only if conditional dynamics are allowed. Here we present a setup in which we repeatedly disentangle and reentangle photons in three of four states, so as to separate photons in one of them, conditioned on keeping the other two at bay. The efficiency of a realistic implementation of our setup with current technology is over 90% for an ideal source of photons on demand. © 2011 American Physical Society

    As a means of conveying difficult personal experiences, illness narratives and their analysis have the potential to increase awareness of patients' lives and circumstances. Becoming sensitised to the linguistic texture of narrative offers readers a means of increasing narrative understanding. Using the fictional narrative of The Bell Jar, this paper outlines a novel method for exploring the language of illness narratives. Corpus stylistics provides new insights into narrative texture and demonstrates the importance of recurrent linguistic features in shaping meaning. The paper concludes by proposing the application of a similar methodology to non-fictional illness narratives in therapeutic contexts.

    We present a setup for quantum cryptography based on photon pairs in energy-time Bell states and show its feasibility in a laboratory experiment. Our scheme combines the advantages of using photon pairs instead of faint laser pulses and the possibility to preserve energy-time entanglement over long distances. Moreover, using four-dimensional energy-time states, no fast random change of bases is required in our setup: Nature itself decides whether to measure in the energy or in the time base, thus rendering eavesdropper attacks based on "photon number splitting" less efficient.

À semelhança do romance de Umberto Eco, A misteriosa chama da rainha Loana, que reproduz imagens da cultura pop e erudita em meio à sua narrativa, o texto segue o formato de ensaio ilustrado, fundindo a ficção com os aspectos reais da Paris na efervescência da Belle Époque. A estrutura, portanto, rompe com os gêneros tradicionais dos artigos acadêmicos, apresentando conteúdo reflexivo por meios dos personagens e da trama engendrada. Palavras-chave: Paris; Belle Époque; modernidade; imagens; publicidade. ABSTRACT In the style of Baudelaire’s texts on the flâneurs who used to walk in the city of Paris, finding the symbols of modernity, this article narrates the ar- rival of a foreigner in the early 20th century in Paris, and his tour around the French capital. In the course of one day, he will be in contact with the works of important artists, such as Toulouse-Lautrec, Murcha and Chéret, who drew posters for shows, products’ packages, advertising leaflets, among other artistic manifestations, explored by the then rising modern spirit. Similar to Umberto Eco’s novel The mysterious flame of Queen Loana, which reproduces images of both pop and erudite culture in its narrative, the text follows the illustrated essay format, merging fiction and the real aspects of Paris’ effervescent Belle Époque. The structure, therefore, breaks free from the traditional genres of academic articles, presenting the

    We calculate the production cross sections for $D^{*+}D^{*-}$, $D^+D^{*-}$ and $D^+D^-$ in $e^+e^-$ annihilation through one virtual photon in the framework of perturbative QCD with constituent quarks. The calculated cross sections for $D^{*+}D^{*-}$ and $D^+D^{*-}$ production are roughly in agreement with the recent Belle data. The helicity decomposition for $D^{*}$ meson production is also calculated. The fraction of the $D^{*\\pm}_LD^{*\\mp}_T$ final state in $e^+e^-\\to D^{*+}D^{*-}$ process...

    We report on a design and performances of a monitoring system developed for the aerogel Cherenkov counters (ACC) of the BELLE detector. The system consists of blue LEDs, a diffuser box, and optical distributors which distribute the LED light to the ACC modules. The employed LED (NSPB series) has been observed to have high reliability on the long term stability and the temprature dependence. The diffuser box is employed to reduce the intrinsic non-uniformity of the LED light intensity. The overall performances of the present monitoring system on uniformity and intensity of the light output have been found to satisfy all the requirements for the monitoring.

    Isolated sternal fractures are very rare in children. Pain management is the method of choice, but surgery may be indicated in selected cases with dislocated fractures. However, the indication for open reduction of sternal fractures is discussed controversially. To the best of our knowledge, we present the first report of a child with displaced isolated sternal fracture who was successfully treated by conservative means using a vacuum bell. © The Author(s) 2018.

    The Belle and Babar experiments have measured the branching fractions for B{sup +} {yields} {tau}{sup +}{nu} and D{sub s}{sup +} {yields} {mu}{sup +}{nu} decays. From these measurements one can extract the B{sup +} and D{sub s}{sup +} decay constants, which can be compared to lattice QCD calculations. For the D{sub s}{sup +} decay constant, there is currently a 2.1 {sigma} difference between the calculated value and the measured value.

  1. The influence of far-red light on attributes of green bell pepper fruits (Capsicum annuum l. during storage

    2016-12-01

    Full Text Available Green bell peppers fruits, stored for 1 month at 8oC and 455% relative humidity in Far-Red light (FRL and darkness respectively, were investigated in terms of physical, chemical and microbiological parameters. The exposure to FRL slows down the water loss from fruits by stimulating the surface wax biosynthesis into a higher specific amount and hydrophobic nature and reducing the apertures, diameters of the pericarp cells, intercellular walls and dermal layer thicknesses. The higher level of catalase enzyme in the FRL-exposed fruits resulted in lower chilling injury index in comparison with the one in fruits exposed to darkness. FRL has favorable effect on chlorophyll and carotenoids accumulation rates. The multiplication of yeasts and molds on the surface of FRL-exposed bell peppers was significantly delayed as compared to the multiplication on the surface of the darkness-exposed bell peppers.

    Full Text Available An association between AS03 adjuvanted pandemic influenza vaccine and the occurrence of Bell's palsy was found in a population based cohort study in Stockholm, Sweden. To evaluate this association in a different population, we conducted a self-controlled case series in a primary health care database, THIN, in the United Kingdom. The aim of this study was to determine whether there was an increased risk of Bell's palsy following vaccination with any influenza vaccine containing A/California/7/2009 (H1N1-like viral strains. Secondly, we investigated whether risks were different following pandemic influenza A(H1N1pdm09 vaccines and seasonal influenza vaccines containing the influenza A(H1N1pdm09 strain.The study population comprised all incident Bell's palsy cases between 1 June 2009 and 30 June 2013 identified in THIN. We determined the relative incidence (RI of Bell's palsy during the 6 weeks following vaccination with either pandemic or seasonal influenza vaccine. All analyses were adjusted for seasonality and confounding variables.We found an incidence rate of Bell's palsy of 38.7 per 100,000 person years. Both acute respiratory infection (ARI consultations and pregnancy were found to be confounders. When adjusted for seasonality, ARI consultations and pregnancies, the RI during the 42 days after vaccination with an influenza vaccine was 0.85 (95% CI: 0.72-1.01. The RI was similar during the 42 days following seasonal vaccine (0.96, 95%CI: 0.82-1.13 or pandemic vaccine (0.73, 95%CI: 0.47-1.12.We found no evidence for an increased incidence of Bell's palsy following seasonal influenza vaccination overall, nor for monovalent pandemic influenza vaccine in 2009.

    Using a single basal application of controlled-release fertilizers for bell peppers is a perspective method, because by the elimination of top-dressings, labour and energy costs can be reduced. In this study, effects of band and nursery pot applications of polyolefin-coated fertilizers (POCF) on bell peppers grown in the field were compared at two different application rates, in 1997 and 1998. As a consequence of continuous nutrient supply, a good yield could be achieved in case of both appli...

  4. Irrelevance of Bell's Theorem for experiments involving correlations in space and time: a specific loophole-free computer-example

    De Raedt, Hans; Hess, Karl

    2016-01-01

    John Bell is generally credited to have accomplished the remarkable "proof" that any theory of physics, which is both Einstein-local and "realistic" (counterfactually definite), results in a strong upper bound to the correlations that are measured in space and time. He thus predicts that Einstein-Podolsky-Rosen experiments cannot violate Bell- type inequalities. We present a counterexample to this claim, based on discrete-event computer simulations. Our model-results fully agree with the predictions of quantum theory for Einstein-Podolsky-Rosen-Bohm experiments and are free of the detection- or a coincidence-loophole.

    2017-03-01

    The Belle II experiment designed to study CP Violation and Beyond Standard model physics at the decays of B-mesons is quickly approaching its first physics run with the SuperKEKB accelerator (Tsukuba, Japan) already under commissioning. To operate in the unique conditions of the Belle II experiment, its vertex detector (VXD) is a six layers silicon detector with two innermost layers of DEPFET active pixel modules and four layers of double-sided strip modules. A section of it will become a commissioning detector for the first collisions of the next-generation high luminosity B-factory. The same setup, from cooling services, mechanical support or sensors and front-end electronics to DAQ, including the software and alignment framework, is tested under an electron beam provided by DESY facilities. We present the basic characteristics of the pixel and strip modules and the setup under test, including software and alignment framework—as close to the final system as possible.

  7. Study of improved K{sub S}{sup 0} detection at the Belle II detector

    2016-07-01

    In the near future, the Belle II experiment at the SuperKEKB accelerator at KEK in Tsukuba, Japan, will start operation at a luminosity a factor 40 higher than its predecessor experiment, Belle. The physics program includes the search for physics beyond the Standard Model of particle physics by the investigation of CP violating processes and rare B meson decays. Many important decay channels involve K{sub S}{sup 0} mesons. The detector features two layers of silicon pixel cells (PXD) closest to the interaction point surrounded by four layers of double sided silicon strip detectors (SVD). The high background level of the Pixel Detector requires an online data reduction system: Using the SVD and the surrounding detectors, the online reconstructed tracks of charged particles are extrapolated to the PXD layers, where Regions of Interest (ROIs) are defined around the intercepts. Only the pixel data inside these ROIs are stored. Thus, particles creating an insufficient number of hits in the outer detectors are not reconstructed and subsequently no ROIs are created, resulting in the loss of the related hits in the Pixel Detector. As a consequence, particles creating a sufficient number of hits in all six layers, but not in the outer four, are lost. In this contribution, we perform online tracking using all six layers to find the tracks of pions for improved K{sub S}{sup 0} detection. The combinatorics of the hit-track assignments is reduced by artificial neural networks.

  8. Sonic hedgehog functions as a mitogen during bell stage of odontogenesis.

    2003-01-01

    Epithelial-mesenchymal interactions are required for tissue growth and gene expression patterns during odontogenesis. We showed previously that Sonic hedgehog (SHH) is detectable in both dental epithelium and mesenchyme, while Shh transcripts are present in dental epithelium only, suggesting that SHH functions as an autocrine signal in epithelium and a paracrine signal in mesenchyme. This hypothesis was tested here. We found by in situ hybridization that the SHH autocrine receptor Ptch-2 is indeed expressed in dental epithelium whereas the paracrine receptor Ptc is expressed in mesenchyme. Bovine bell stage tooth germs were microsurgically separated into epithelial and mesenchymal portions and the resulting tissue fragments were organ-cultured. In epithelium fragments cultured by themselves, gene expression of Shh and Gli-1 (a putative transcriptional mediator of hedgehog signaling) was significantly decreased in both inner dental epithelium and stratum intermedium layers; this was accompanied by a sharp drop in epithelial cell proliferation. However, in companion control tissue fragments containing both epithelium and mesenchyme, Shh and Gli-1 expression as well as cell proliferation were maintained. Treatment of dental epithelial or mesenchymal cell populations in monolayer cultures with exogenous recombinant SHH stimulated cell proliferation. Together, the data provide clear evidence that Shh is synthesized by dental epithelium, reaches the underlying mesenchyme, and appears to act as an autocrine mitogen for epithelial cells and a paracrine mitogen for mesenchymal cells, thus exerting crucial functions in tooth germ growth, morphogenesis, and tissue-tissue interactions of bell stage of odontogenesis.

  9. The Neuro-Z-Vertex Trigger of the Belle II Experiment

    Skambraks, Sebastian; Neuhaus, Sara; Kiesling, Christian

    2016-11-01

    A neural network z vertex trigger is planned for the upcoming Belle II detector at the SuperKEKB collider. This neural algorithm is based on a single track 3D parameter estimation using only hit and drift time information from the central drift chamber. Due to the high luminosity (L = 8 × 1035 cm-2 s-1) Belle II will have to face high levels of beam induced background, making a z vertex reconstruction at the first level trigger mandatory. Using the neural z vertex algorithm, the requirements of the standard track trigger can be strongly relaxed. By this, the trigger efficiencies, especially for low multiplicity events, e.g. τ pair production, can be significantly increased. This contribution presents the foreseen neural network trigger setup and the preceding 2D track finder. Special focus is put on the proposal and evaluation of a possible 3D upgrade of the 2D track finder. Additionally, details are given on a dedicated setup for the upcoming cosmic ray test.

    Full Text Available Grafting favors the presence of bioactive compounds in the bell pepper, but many species and varieties have not yet been analyzed in this sense, including commonly grafted varieties. The aim of the present study is to characterize the content in β-carotenes, vitamin C, lycopene, total phenols, and the antioxidant activity of bell pepper (Capsicum annum L. using the cultivar/rootstock combinations: Jeanette/Terrano (yellow, Sweet/Robusto (green, Fascinato/Robusto (red, Orangela/Terrano (orange, and Fascinato/Terrano (red. The plants were grown in a net-shading system and harvested on three sampling dates of the same crop cycle. The results show statistical differences (p ≤ 0.05 between cultivar/rootstock combinations and sampling dates for the content in bioactive compounds and antioxidant activity. Fascinato/Robusto presented the highest concentration of lycopene and total phenols as well as the greatest antioxidant activity of all cultivar/rootstock combinations evaluated. In addition, it was found that the best sampling time for the peppers to have the highest concentrations of bioactive compounds and antioxidant activity was September.

  11. How the Relativistic Motion Affect Quantum Fisher Information and Bell Non-locality for Multipartite state.

    2017-02-01

    In this work, the quantum fisher information (QFI) and Bell non-locality of a multipartite fermionic system are investigated. Unlike the currently existing research of QFI, we focus our attention on the differences between quantum fisher information and Bell non-locality under the relativistic framework. The results show that although the relativistic motion affects the strength of the non-locality, it does not change the physical structure of non-locality. However, unlike the case of non-locality, the relativistic motion not only influence the precision of the QFI F ϕ but also broke the symmetry of the function F ϕ . The results also show that for a special multipartite system, , the number of particles of a initial state do not affect the F θ . Furthermore, we also find that F θ is completely unaffected in non-inertial frame if there are inertial observers. Finally, in view of the decay behavior of QFI and non-locality under the non-inertial frame, we proposed a effective scheme to battle against Unruh effect.

  12. Exercise, oxidants, and antioxidants change the shape of the bell-shaped hormesis curve

    Directory of Open Access Journals (Sweden)

    Zsolt Radak

    2017-08-01

    Full Text Available It is debated whether exercise-induced ROS production is obligatory to cause adaptive response. It is also claimed that antioxidant treatment could eliminate the adaptive response, which appears to be systemic and reportedly reduces the incidence of a wide range of diseases. Here we suggest that if the antioxidant treatment occurs before the physiological function-ROS dose-response curve reaches peak level, the antioxidants can attenuate function. On the other hand, if the antioxidant treatment takes place after the summit of the bell-shaped dose response curve, antioxidant treatment would have beneficial effects on function. We suggest that the effects of antioxidant treatment are dependent on the intensity of exercise, since the adaptive response, which is multi pathway dependent, is strongly influenced by exercise intensity. It is further suggested that levels of ROS concentration are associated with peak physiological function and can be extended by physical fitness level and this could be the basis for exercise pre-conditioning. Physical inactivity, aging or pathological disorders increase the sensitivity to oxidative stress by altering the bell-shaped dose response curve.

    Full Text Available ABSTRACT The objective of this study was to evaluate the effect of energized water and bovine biofertilizer doses on the gas exchange and NPK contents in leaves of yellow bell pepper plants. The experiment was conducted at the experimental area of the Federal University of Ceará, in Fortaleza-CE, Brazil, from June to November 2011. The experiment was set in a randomized block design, in a split-plot scheme; the plots were composed of treatments with energized and non-energized water and the subplots of five doses of liquid biofertilizer (0, 250, 500, 750 and 1000 mL plant-1 week-1. The following variables were analyzed: transpiration, stomatal conductance, photosynthesis and leaf contents of nitrogen (N, phosphorus (P and potassium (K. Water energization did not allow significant increases in the analyzed variables. The use of biofertilizer as the only source of fertilization was sufficient to provide the nutrients N, P and K at appropriate levels for the bell pepper crop.

    Growth of isolated axial heterojunction nanowires by a solution phase growth process is reported. The dumb-bell shaped nanowires contain two silver telluride sections at the extremes joined by a tellurium section. Reaction of silver nitrate with tellurium NWs in aqueous solution at a molar ratio of 1 : 1 leads to the formation of amorphous partially silver reacted Te NWs. Low temperature (75 °C) solution phase annealing of these silver deficient NWs results in phase segregation producing crystalline Ag(2)Te and Te phases with clear phase boundaries along the wire axis. Structural characterization of these dumb-bell shaped NWs was performed with different microscopic and spectroscopic tools. Solution phase silver concentration over the course of annealing indicated leaching of silver into the solution during the formation of biphasic NWs. Similar Ag : Te ratios were observed in both partially silver reacted Te NWs and phase segregated Ag(2)Te-Te-Ag(2)Te NWs and this was attributed to redeposition of leached silver on the amorphous NW tips which eventually resulted in complete phase segregation. Successful integration of different chemical components in single NWs is expected to open up new application possibilities as physical and chemical properties of the heterostructure can be exploited.

  16. Immediate Postoperative Bell's Palsy: Viral Etiology or Post-Traumatic Phenomena?

    Full Text Available Introduction: Bell’s palsy is a sudden unilateral paralysis of the facial nerve. Postoperative Bell’s palsy following surgery is rare. It occurs in less than 1% of operations. The hypothesis: We premise that the main cause of immediate postoperative Bell's palsy is latent herpes viruses (herpes simplex virus type 1 and herpes zoster virus, which are reactivated from cranial nerve ganglia. Inflammation of the nerve initially results in a reversible neurapraxia, but ultimately Wallerian degeneration ensues. The palsy is often sudden in onset and evolves rapidly, with maximal facial weakness developing within two days. Associated symptoms of-ten seen in idiopathic Bell’s palsy are tearing problems, hyperacusis and altered taste.Evaluation of the hypothesis: Facial paralysis presenting postoperatively is distressing and poses a diagnostic chal-lenge. A complete interruption of the facial nerve at the sty-lomastoid foramen paralyzes all the muscles of facial expression. Taste sensation may be lost unilaterally and hye-racusis may be present. Idiopathic Bell’s palsy is due to inflammation of the facial nerve in the facial canal. Bell’s palsy may also occur from lesions that invade the temporal bone (carotid body, cholesteatoma, dermoid cyst, acoustic neu-romas. Although traumatic Bell’s palsy cannot be ruled out, it seems logic to postulate that the main cause of immediate postoperative Bell's palsy is latent herpes viruses.

    The Marcus theory of electron transfer predicts a bell-shaped dependence of the reaction rate on the reaction free energy. The top of the "inverted parabola" corresponds to zero activation barrier when the electron-transfer reorganization energy and the reaction free energy add up to zero. Although this point has traditionally been reached by altering the chemical structures of donors and acceptors, the theory suggests that it can also be reached by varying other parameters of the system including temperature. We find here dramatic evidence of this phenomenon from experiments on a fullerene-porphyrin dyad. Following photoinduced electron transfer, the rate of charge recombination shows a bell-shaped dependence on the inverse temperature, first increasing with cooling and then decreasing at still lower temperatures. This non-Arrhenius rate law is a result of a strong, approximately hyperbolic temperature variation of the reorganization energy and the reaction free energy. Our results provide potentially the cleanest confirmation of the Marcus energy gap law so far since no modification of the chemical structure is involved.

  18. The NASA/industry Design Analysis Methods for Vibrations (DAMVIBS) program : Bell Helicopter Textron accomplishments

    Accurate vibration prediction for helicopter airframes is needed to 'fly from the drawing board' without costly development testing to solve vibration problems. The principal analytical tool for vibration prediction within the U.S. helicopter industry is the NASTRAN finite element analysis. Under the NASA DAMVIBS research program, Bell conducted NASTRAN modeling, ground vibration testing, and correlations of both metallic (AH-1G) and composite (ACAP) airframes. The objectives of the program were to assess NASTRAN airframe vibration correlations, to investigate contributors to poor agreement, and to improve modeling techniques. In the past, there has been low confidence in higher frequency vibration prediction for helicopters that have multibladed rotors (three or more blades) with predominant excitation frequencies typically above 15 Hz. Bell's findings under the DAMVIBS program, discussed in this paper, included the following: (1) accuracy of finite element models (FEM) for composite and metallic airframes generally were found to be comparable; (2) more detail is needed in the FEM to improve higher frequency prediction; (3) secondary structure not normally included in the FEM can provide significant stiffening; (4) damping can significantly affect phase response at higher frequencies; and (5) future work is needed in the areas of determination of rotor-induced vibratory loads and optimization.

    Grafting favors the presence of bioactive compounds in the bell pepper, but many species and varieties have not yet been analyzed in this sense, including commonly grafted varieties. The aim of the present study is to characterize the content in β-carotenes, vitamin C, lycopene, total phenols, and the antioxidant activity of bell pepper (Capsicum annum L) using the cultivar/rootstock combinations: Jeanette/Terrano (yellow), Sweet/Robusto (green), Fascinato/Robusto (red), Orangela/Terrano (orange), and Fascinato/Terrano (red). The plants were grown in a net-shading system and harvested on three sampling dates of the same crop cycle. The results show statistical differences (p ≤ 0.05) between cultivar/rootstock combinations and sampling dates for the content in bioactive compounds and antioxidant activity. Fascinato/Robusto presented the highest concentration of lycopene and total phenols as well as the greatest antioxidant activity of all cultivar/rootstock combinations evaluated. In addition, it was found that the best sampling time for the peppers to have the highest concentrations of bioactive compounds and antioxidant activity was September. PMID:26783714
