  1. Exceptional phenomenology

    DEFF Research Database (Denmark)

    Aggerholm, Kenneth; Moltke Martiny, Kristian

    Phenomenological research is in traditional terms a matter of going 'back to the things themselves', as Husserl famously stated. But if phenomenology is to renew itself in creative ways and reveal new aspects of human experience it is of value to look for a certain kind of phenomena: exceptions. ...

  2. AMERICAN EXCEPTIONALISM

    Full Text Available In an interconnected world where foreign relations matter not only for resources or military alliances but also for cultural relationships, it is highly important to have a better understanding of the power relations among nations. The information carries certain meanings that have important outcomes thus defining the power of a given nation. Foreign policy is the channel through which global politics is exercised. International politics is a hierarchy of power being determined by important cultural, economic as well as geographical aspects. The reasons and strategies that are used in order to reach the outcomes in global politics represent the focus of the present paper. The United States has been the leader in international politics since the early 20th century due to its vast resources and wealth as well as its cultural output. America’s interest in preserving a democratic and free world has its foundation in the beliefs and values it stands for the aim of this paper is to question whether or not there is a concrete premise for the idea of American exceptionalism.

    An account is given of the exceptional memory of the late Professor A. C. Aitken who was also a distinguished mathematician and mental calculator. Compared with Shereshevskii, another man with exceptional memory, he shows the scholar's reliance on conceptual mapping rather than the mnemonist's reliance on perceptual chaining. (Editor)

  4. MFTF exception handling system

    International Nuclear Information System (INIS)

    Nowell, D.M.; Bridgeman, G.D.

    1979-01-01

    In the design of large experimental control systems, a major concern is ensuring that operators are quickly alerted to emergency or other exceptional conditions and that they are provided with sufficient information to respond adequately. This paper describes how the MFTF exception handling system satisfies these requirements. Conceptually exceptions are divided into one of two classes. Those which affect command status by producing an abort or suspend condition and those which fall into a softer notification category of report only or operator acknowledgement requirement. Additionally, an operator may choose to accept an exception condition as operational, or turn off monitoring for sensors determined to be malfunctioning. Control panels and displays used in operator response to exceptions are described

  5. On exceptional instanton strings

    Del Zotto, M.; Lockhart, G.

    According to a recent classification of 6d (1, 0) theories within F-theory there are only six “pure” 6d gauge theories which have a UV superconformal fixed point. The corresponding gauge groups are SU(3), SO(8), F4, E6, E7, and E8. These exceptional models have BPS strings which are also instantons

  7. Exceptionalism and globalism

    Directory of Open Access Journals (Sweden)

    John Cairns Jr

    2001-03-01

    Full Text Available ABSTRACT: Achieving sustainable use of the planet will require ethical judgments in both sciences and environmental politics. The purpose of this editorial is to discuss two paradigms, exceptionalism and globalism, that are important in this regard. Exceptionalism is the insistence that one set of rules or behaviors is acceptable for an individual or country but that a different set should be used for the rest of the world. For example, the disparity in per capita consumption of resources and economic status has increased dramatically in the last century, but the consumers of great amounts of resources do not feel a proportionate responsibility for addressing this issue. Globalism is defined as individual and societal willingness to diminish, postpone or forgo individual natural resource use to protect and enhance the integrity of the global ecological life support system. Increasing affluence and the still increasing human population, coupled with wide dissemination of information and an increasing awareness that humans occupy a finite planet, exacerbate this already difficult situation. Increased interest in sustainable use of the planet makes open discussion of these issues mandatory because individuals cannot function in isolation from the larger society of which they are a part. Similarly, no country can function in isolation from other countries, which collectively form an interactive mosaic. This discussion identifies some of the crucial issues related to exceptionalism and globalism, which must be addressed before sustainable use of the planet can be achieved.

    We study the dark matter phenomenology of non-minimal composite Higgs models with SO(7) broken to the exceptional group G{sub 2}. In addition to the Higgs, three pseudo-Nambu-Goldstone bosons arise, one of which is electrically neutral. A parity symmetry is enough to ensure this resonance is stable. In fact, if the breaking of the Goldstone symmetry is driven by the fermion sector, this Z{sub 2} symmetry is automatically unbroken in the electroweak phase. In this case, the relic density, as well as the expected indirect, direct and collider signals are then uniquely determined by the value of the compositeness scale, f. Current experimental bounds allow one to account for a large fraction of the dark matter of the Universe if the dark matter particle is part of an electroweak triplet. The totality of the relic abundance can be accommodated if instead this particle is a composite singlet. In both cases, the scale f and the dark matter mass are of the order of a few TeV. (orig.)

    2003-01-01

    Full Text Available Exception handling is nowadays a necessary component of error proof information systems. The paper presents overview of techniques and models of exception handling, problems connected with them and potential solutions. The aspects of implementation of propagation mechanisms and exception handling, their effect on semantics and general program efficiency are also taken into account. Presented mechanisms were adopted to modern programming languages. Considering design area, formal methods and formal verification of program properties we can notice exception handling mechanisms are weakly present what makes a field for future research.

  13. Exceptional groups from open strings

    International Nuclear Information System (INIS)

    Gaberdiel, M.R.; Zwiebach, B.

    1998-01-01

    We consider type IIB theory compactified on a two-sphere in the presence of mutually non-local 7-branes. The BPS states associated with the gauge vectors of exceptional groups are seen to arise from open strings connecting the 7-branes, and multi-pronged open strings capable of ending on more than two 7-branes. These multi-pronged strings are built from open string junctions that arise naturally when strings cross 7-branes. The different string configurations can be multiplied as traditional open strings, and are shown to generate the structure of exceptional groups. (orig.)

  18. CMS : An exceptional load for an exceptional work site

    CERN Multimedia

    2001-01-01

    Components of the CMS vacuum tank have been delivered to the detector assembly site at Cessy. The complete inner shell was delivered to CERN by special convoy while the outer shell is being assembled in situ. The convoy transporting the inner shell of the CMS vacuum tank took a week to cover the distance between Lons-le-Saunier and Point 5 at Cessy. Left: the convoy making its way down from the Col de la Faucille. With lights flashing, flanked by police outriders and with roads temporarily closed, the exceptional load that passed through the Pays de Gex on Monday 20 May was accorded the same VIP treatment as a leading state dignitary. But this time it was not the identity of the passenger but the exceptional size of the object being transported that made such arrangements necessary. A convoy of two lorries was needed to transport the load, an enormous 13-metre long, 6 metre diameter cylinder weighing 120 tonnes. It took a week to cover the 120 kilometres between Lons-le-Saunier and the assembly site for...

  19. Exceptional circles of radial potentials

    International Nuclear Information System (INIS)

    Music, M; Perry, P; Siltanen, S

    2013-01-01

    A nonlinear scattering transform is studied for the two-dimensional Schrödinger equation at zero energy with a radial potential. Explicit examples are presented, both theoretically and computationally, of potentials with nontrivial singularities in the scattering transform. The singularities arise from non-uniqueness of the complex geometric optics solutions that define the scattering transform. The values of the complex spectral parameter at which the singularities appear are called exceptional points. The singularity formation is closely related to the fact that potentials of conductivity type are ‘critical’ in the sense of Murata. (paper)

  20. X exceptionalism in Caenorhabditis speciation.

    Science.gov (United States)

    Cutter, Asher D

    2017-11-13

    Speciation genetics research in diverse organisms shows the X-chromosome to be exceptional in how it contributes to "rules" of speciation. Until recently, however, the nematode phylum has been nearly silent on this issue, despite the model organism Caenorhabditis elegans having touched most other topics in biology. Studies of speciation with Caenorhabditis accelerated with the recent discovery of species pairs showing partial interfertility. The resulting genetic analyses of reproductive isolation in nematodes demonstrate key roles for the X-chromosome in hybrid male sterility and inviability, opening up new understanding of the genetic causes of Haldane's rule, Darwin's corollary to Haldane's rule, and enabling tests of the large-X effect hypothesis. Studies to date implicate improper chromatin regulation of the X-chromosome by small RNA pathways as integral to hybrid male dysfunction. Sexual transitions in reproductive mode to self-fertilizing hermaphroditism inject distinctive molecular evolutionary features into the speciation process for some species. Caenorhabditis also provides unique opportunities for analysis in a system with XO sex determination that lacks a Y-chromosome, sex chromosome-dependent sperm competition differences and mechanisms of gametic isolation, exceptional accessibility to the development process and rapid experimental evolution. As genetic analysis of reproductive isolation matures with investigation of multiple pairs of Caenorhabditis species and new species discovery, nematodes will provide a powerful complement to more established study organisms for deciphering the genetic basis of and rules to speciation. © 2017 John Wiley & Sons Ltd.

  1. The physics of exceptional points

    International Nuclear Information System (INIS)

    Heiss, W D

    2012-01-01

    A short résumé is given about the nature of exceptional points (EPs) followed by discussions about their ubiquitous occurrence in a great variety of physical problems. EPs feature in classical as well as in quantum mechanical problems. They are associated with symmetry breaking for PT-symmetric Hamiltonians, where a great number of experiments has been performed, in particular in optics, and to an increasing extent in atomic and molecular physics. EPs are involved in quantum phase transition and quantum chaos; they produce dramatic effects in multichannel scattering, specific time dependence and more. In nuclear physics, they are associated with instabilities and continuum problems. Being spectral singularities they also affect approximation schemes. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Quantum physics with non-Hermitian operators’. (paper)

  6. From Ethical Exceptionalism to Ethical Exceptions: The Rule and exception Model and the Changing Meaning of Ethics In German Bioregulation.

    Science.gov (United States)

    Braun, Kathrin

    2017-12-01

    Germany is an interesting case with respect to the governance of reprogenetics. It has a strong profile in the technosciences and high aims regarding the global bioeconomy, yet her regulation of human genetics, reproductive medicine and embryo research has for a long time been rather restrictive. German biopolitical exceptionalism has often been explained by reference to Catholicism and the legacy of the Nazi past. The Germans, so goes the common story, have learnt the lessons of history and translated them into unconditional respect for human dignity, which in turn translates into unconditional protection of human life, including the human embryo, and the firm repudiation of any eugenic distinction between 'life worth to live' and 'life not worth to live'. This, however, is not the whole story. Alongside deontological strictness we find another strand of governing body politics and reprogenetics in Germany, the rule-and-exception model, running from the mid-1970s abortion law via the 2002 Stem Cell Act to the 2011 regulation of pre-implantation genetic diagnosis. In contrast to the former, that strongly draws on Kant and his concept of human dignity, the latter bears resemblances to Carl Schmitt's concept of state of exception. The article will show that the rule-and-exception model builds the exception into the rule and transforms the meaning and mandate of ethics, namely from safeguarding ethical standards to deciding about the exception. Given that the exception has now tended to become the rule, the question is whether the lessons of history will govern German reprogenetics for much longer. © 2016 John Wiley & Sons Ltd.

  9. Statistical tests to compare motif count exceptionalities

    Directory of Open Access Journals (Sweden)

    Vandewalle Vincent

    2007-03-01

    Full Text Available Abstract Background Finding over- or under-represented motifs in biological sequences is now a common task in genomics. Thanks to p-value calculation for motif counts, exceptional motifs are identified and represent candidate functional motifs. The present work addresses the related question of comparing the exceptionality of one motif in two different sequences. Just comparing the motif count p-values in each sequence is indeed not sufficient to decide if this motif is significantly more exceptional in one sequence compared to the other one. A statistical test is required. Results We develop and analyze two statistical tests, an exact binomial one and an asymptotic likelihood ratio test, to decide whether the exceptionality of a given motif is equivalent or significantly different in two sequences of interest. For that purpose, motif occurrences are modeled by Poisson processes, with a special care for overlapping motifs. Both tests can take the sequence compositions into account. As an illustration, we compare the octamer exceptionalities in the Escherichia coli K-12 backbone versus variable strain-specific loops. Conclusion The exact binomial test is particularly adapted for small counts. For large counts, we advise to use the likelihood ratio test which is asymptotic but strongly correlated with the exact binomial test and very simple to use.

  11. Amendments to excepted benefits. Final rules.

    Science.gov (United States)

    2014-10-01

    This document contains final regulations that amend the regulations regarding excepted benefits under the Employee Retirement Income Security Act of 1974, the Internal Revenue Code (the Code), and the Public Health Service Act. Excepted benefits are generally exempt from the health reform requirements that were added to those laws by the Health Insurance Portability and Accountability Act and the Patient Protection and Affordable Care Act. In addition, eligibility for excepted benefits does not preclude an individual from eligibility for a premium tax credit under section 36B of the Code if an individual chooses to enroll in coverage under a Qualified Health Plan through an Affordable Insurance Exchange. These regulations finalize some but not all of the proposed rules with minor modifications; additional guidance on limited wraparound coverage is forthcoming.

    We formulate the full bosonic SL(5) exceptional field theory in a coordinate-invariant manner. Thereby we interpret the 10-dimensional extended space as a manifold with SL(5)×ℝ{sup +}-structure. We show that the algebra of generalised diffeomorphisms closes subject to a set of closure constraints which are reminiscent of the quadratic and linear constraints of maximal seven-dimensional gauged supergravities, as well as the section condition. We construct an action for the full bosonic SL(5) exceptional field theory, even when the SL(5)×ℝ{sup +}-structure is not locally flat.

    To assess lifestyle factors including physical activity, smoking, alcohol consumption, and dietary habits in men and women with exceptional longevity. Retrospective cohort study. A cohort of community-dwelling Ashkenazi Jewish individuals with exceptional longevity defined as survival and living independently at age 95 and older. Four hundred seventy-seven individuals (mean 97.3 ± 2.8, range 95-109; 74.6% women) and a subset of participants of the National Health and Nutrition Examination Survey (NHANES) I (n = 3,164) representing the same birth cohort as a comparison group. A trained interviewer administrated study questionnaires to collect information on lifestyle factors and collected data on anthropometry. People with exceptional longevity had similar mean body mass index (men, 25.4 ± 2.8 kg/m² vs 25.6 ± 4.0 kg/m² , P=.63; women, 25.0 ± 3.5 kg/m² vs 24.9 ± 5.4 kg/m² ; P = .90) and a similar proportion of daily alcohol consumption (men, 23.9 vs 22.4, P = .77; women, 12.1 vs 11.3, P = .80), of regular physical activity (men: 43.1 vs 57.2; P = .07; women: 47.0 vs 44.1, P = .76), and of a low-calorie diet (men: 20.8 vs 21.1, P=.32; women: 27.3 vs 27.1, P=.14) as the NHANES I population. People with exceptional longevity are not distinct in terms of lifestyle factors from the general population, suggesting that people with exceptional longevity may interact with environmental factors differently than others.

    2015-01-01

    Full Text Available We report an exceptional complex chromosomal rearrangement (CCR found in three individuals in a family that involves 4 chromosomes with 5 breakpoints. The CCR was ascertained in a phenotypically abnormal newborn with additional chromosomal material on the short arm of chromosome 4. Maternal karyotyping indicated that the mother carried an apparently balanced CCR involving chromosomes 4, 6, 11, and 18. Maternal transmission of the derivative chromosome 4 resulted in partial trisomy for chromosomes 6q and 18q and a partial monosomy of chromosome 4p in the proband. Further family studies found that the maternal grandmother carried the same apparently balanced CCR as the proband’s mother, which was confirmed using the whole chromosome painting (WCP FISH. High resolution whole genome microarray analysis of DNA from the proband’s mother found no evidence for copy number imbalance in the vicinity of the CCR translocation breakpoints, or elsewhere in the genome, providing evidence that the mother’s and grandmother’s CCRs were balanced at a molecular level. This structural rearrangement can be categorized as an exceptional CCR due to its complexity and is a rare example of an exceptional CCR being transmitted in balanced and/or unbalanced form across three generations.

  9. Exceptional points in open quantum systems

    International Nuclear Information System (INIS)

    Mueller, Markus; Rotter, Ingrid

    2008-01-01

    Open quantum systems are embedded in the continuum of scattering wavefunctions and are naturally described by non-Hermitian Hamilton operators. In the complex energy plane, exceptional points appear at which two (or more) eigenvalues of the Hamilton operator coalesce. Although they are a countable set of single points in the complex energy plane and therefore of measure zero, they determine decisively the dynamics of open quantum systems. A powerful method for the description of open quantum systems is the Feshbach projection operator formalism. It is used in the present paper as a basic tool for the study of exceptional points and of the role they play for the dynamics of open quantum systems. Among others, the topological structure of the exceptional points, the rigidity of the phases of the eigenfunctions in their vicinity, the enhancement of observable values due to the reduced phase rigidity and the appearance of phase transitions are considered. The results are compared with existing experimental data on microwave cavities. In the last section, some questions being still unsolved, are considered

    Full Text Available Anal adenocarcinoma is very rare and usually occurs in the elderly. We present a case of a 12-year-old girl with an anal margin painful tumor infiltrating the lower rectum, with perineal and vulvar permeation nodules and bilateral fixed inguinal and iliac lymph nodes. Histology showed anal adenocarcinoma with mucosecreting component and independent cells. She had no extra pelvic metastasis on CT scan. She underwent a colostomy and palliative care. This exceptional case challenges us on the diversity of forms of anal cancers that require a multidisciplinary approach. The precarious social context and the age of onset make it difficult to manage this rare cancer.

    Reid B. Stevens

    2018-04-01

    Full Text Available The hydraulic fracturing boom in Texas required massive water flows. Beginning in the summer of 2011, water became scarce as a prolonged heat wave and subsequent severe drought spread across the state. Oil and gas producers working in drought areas needed to purchase expensive local water or transport water from a non-drought county far from the drill site. In response to decreased water availability in drought areas, these producers completed fewer wells and completed wells that used less water. This decrease in well-level water use had a measurable effect on the amount of oil and gas produced by wells completed during exceptional conditions.

  13. Generalized IIB supergravity from exceptional field theory

    The background underlying the η-deformed AdS{sub 5}×S{sup 5} sigma-model is known to satisfy a generalization of the IIB supergravity equations. Their solutions are related by T-duality to solutions of type IIA supergravity with non-isometric linear dilaton. We show how the generalized IIB supergravity equations can be naturally obtained from exceptional field theory. Within this manifestly duality covariant formulation of maximal supergravity, the generalized IIB supergravity equations emerge upon imposing on the fields a simple Scherk-Schwarz ansatz which respects the section constraint.

  15. Exceptional quantum geometry and particle physics

    Directory of Open Access Journals (Sweden)

    Michel Dubois-Violette

    2016-11-01

    Full Text Available Based on an interpretation of the quark–lepton symmetry in terms of the unimodularity of the color group SU(3 and on the existence of 3 generations, we develop an argumentation suggesting that the “finite quantum space” corresponding to the exceptional real Jordan algebra of dimension 27 (the Euclidean Albert algebra is relevant for the description of internal spaces in the theory of particles. In particular, the triality which corresponds to the 3 off-diagonal octonionic elements of the exceptional algebra is associated to the 3 generations of the Standard Model while the representation of the octonions as a complex 4-dimensional space C⊕C3 is associated to the quark–lepton symmetry (one complex for the lepton and 3 for the corresponding quark. More generally it is suggested that the replacement of the algebra of real functions on spacetime by the algebra of functions on spacetime with values in a finite-dimensional Euclidean Jordan algebra which plays the role of “the algebra of real functions” on the corresponding almost classical quantum spacetime is relevant in particle physics. This leads us to study the theory of Jordan modules and to develop the differential calculus over Jordan algebras (i.e. to introduce the appropriate notion of differential forms. We formulate the corresponding definition of connections on Jordan modules.

  16. Exceptional confinement in G(2) gauge theory

    International Nuclear Information System (INIS)

    Holland, K.; Minkowski, P.; Pepe, M.; Wiese, U.-J.

    2003-01-01

    We study theories with the exceptional gauge group G(2). The 14 adjoint 'gluons' of a G(2) gauge theory transform as {3}, {3-bar} and {8} under the subgroup SU(3), and hence have the color quantum numbers of ordinary quarks, anti-quarks and gluons in QCD. Since G(2) has a trivial center, a 'quark' in the {7} representation of G(2) can be screened by 'gluons'. As a result, in G(2) Yang-Mills theory the string between a pair of static 'quarks' can break. In G(2) QCD there is a hybrid consisting of one 'quark' and three 'gluons'. In supersymmetric G(2) Yang-Mills theory with a {14} Majorana 'gluino' the chiral symmetry is Z(4) χ . Chiral symmetry breaking gives rise to distinct confined phases separated by confined-confined domain walls. A scalar Higgs field in the {7} representation breaks G(2) to SU(3) and allows us to interpolate between theories with exceptional and ordinary confinement. We also present strong coupling lattice calculations that reveal basic features of G(2) confinement. Just as in QCD, where dynamical quarks break the Z(3) symmetry explicitly, G(2) gauge theories confine even without a center. However, there is not necessarily a deconfinement phase transition at finite temperature

  19. Unidirectional reflectionless light propagation at exceptional points

    Directory of Open Access Journals (Sweden)

    Huang Yin

    2017-05-01

    Full Text Available In this paper, we provide a comprehensive review of unidirectional reflectionless light propagation in photonic devices at exceptional points (EPs. EPs, which are branch point singularities of the spectrum, associated with the coalescence of both eigenvalues and corresponding eigenstates, lead to interesting phenomena, such as level repulsion and crossing, bifurcation, chaos, and phase transitions in open quantum systems described by non-Hermitian Hamiltonians. Recently, it was shown that judiciously designed photonic synthetic matters could mimic the complex non-Hermitian Hamiltonians in quantum mechanics and realize unidirectional reflection at optical EPs. Unidirectional reflectionlessness is of great interest for optical invisibility. Achieving unidirectional reflectionless light propagation could also be potentially important for developing optical devices, such as optical network analyzers. Here, we discuss unidirectional reflectionlessness at EPs in both parity-time (PT-symmetric and non-PT-symmetric optical systems. We also provide an outlook on possible future directions in this field.

  20. Leibniz algebroids, twistings and exceptional generalized geometry

    Science.gov (United States)

    Baraglia, D.

    2012-05-01

    We investigate a class of Leibniz algebroids which are invariant under diffeomorphisms and symmetries involving collections of closed forms. Under appropriate assumptions we arrive at a classification which in particular gives a construction starting from graded Lie algebras. In this case the Leibniz bracket is a derived bracket and there are higher derived brackets resulting in an L∞-structure. The algebroids can be twisted by a non-abelian cohomology class and we prove that the twisting class is described by a Maurer-Cartan equation. For compact manifolds we construct a Kuranishi moduli space of this equation which is shown to be affine algebraic. We explain how these results are related to exceptional generalized geometry.

    2018-02-05

    Burkitt's lymphoma (BL) is an exceptional cause of acute renal failure (ARF). The origin of the tumor clone may be lymphoid follicles secondary to renal Epstein-Barr virus (EBV) infection. With the presentation of this clinical case, the pathogenesis, diagnostic criteria and evolution of this extremely rare affection will be discussed. A 4-year-old patient with a recent history of acute osteomyelitis of the right thigh presented an ARF without indications of post-infectious glomerulonephritis. Ultrasound showed enlarged kidneys without dilation of the excretory cavities. Diffuse interstitial infiltration of atypical lymphoid cells of medium size were noted upon renal biopsy. The tumor cells expressed antibodies against CD20, CD10, Bcl6, and Ki67 but not against Bcl2 or CD3. The search for an EBV infection was positive. A few days after diagnosis, the evolution was spontaneously fatal. BL of the kidney is a rare condition that accounts for less than 1 % of kidney tumors, associated almost invariably with EBV infection. The diagnosis is confirmed histologically by renal biopsy and the criteria of Malbrain affirms the primitive character of the lymphoma. BL of the kidney is a diagnostic and therapeutic emergency and may be fatal. Copyright © 2018 Société francophone de néphrologie, dialyse et transplantation. Published by Elsevier Masson SAS.

    We apply exceptional generalised geometry to the study of exactly marginal deformations of N=1 SCFTs that are dual to generic AdS{sub 5} flux backgrounds in type IIB or eleven-dimensional supergravity. In the gauge theory, marginal deformations are parametrised by the space of chiral primary operators of conformal dimension three, while exactly marginal deformations correspond to quotienting this space by the complexified global symmetry group. We show how the supergravity analysis gives a geometric interpretation of the gauge theory results. The marginal deformations arise from deformations of generalised structures that solve moment maps for the generalised diffeomorphism group and have the correct charge under the generalised Reeb vector, generating the R-symmetry. If this is the only symmetry of the background, all marginal deformations are exactly marginal. If the background possesses extra isometries, there are obstructions that come from fixed points of the moment maps. The exactly marginal deformations are then given by a further quotient by these extra isometries. Our analysis holds for any N=2 AdS{sub 5} flux background. Focussing on the particular case of type IIB Sasaki-Einstein backgrounds we recover the result that marginal deformations correspond to perturbing the solution by three-form flux at first order. In various explicit examples, we show that our expression for the three-form flux matches those in the literature and the obstruction conditions match the one-loop beta functions of the dual SCFT.

  3. Stem cell policy exceptionalism: proceed with caution.

    Science.gov (United States)

    Lomax, Geoffrey P; Peckman, Steven R

    2012-06-01

    The term "stem cell exceptionalism" has been used to characterize the policy response to controversies surrounding human embryonic stem cell research. For example, governments and funding agencies have adopted policies governing the derivation and use of human embryonic stem cell lines. These policies have effectively served to fill gaps in existing guidelines and regulations and signal that scientists are committed to a responsible framework for the conduct of research involving human embryos. Recent publications discuss whether ethical and policy issues associated with induced pluripotent cells (iPSCs) from non-embryonic sources create a need for further policy intervention. We suggest many of the issues identified by commentators may be addressed through the application of established policy frameworks governing the use of tissue, human stem cells, and research participation by human research subjects. To the extent, iPSC research intersects with hESC research (e.g. the creation of human gametes and/or embryos), the policy framework governing hESC appears sufficiently robust at this time.

    It is shown that a Hilbert space over the real Clifford algebra C 7 provides a mathematical framework, consistent with the structure of the usual quantum mechanical formalism, for models for the unification of weak, electromagnetic and strong interactions utilizing the exceptional Lie groups. In particular, in case no further structure is assumed beyond that of C 7 , the group of automorphisms leaving invariant a minimal subspace acts, in the ideal generated by that subspace, as G 2 , and the subgroup of this group leaving one generating element (e 7 ) fixed acts, in this ideal, as the color gauge group SU(3). A generalized phase algebra AcontainsC 7 is defined by the requirement that quantum mechanical states can be consistently constructed for a theory in which the smallest linear manifolds are closed over the subalgebra C(1,e 7 ) (isomorphic to the complex field) of C 7 . Eight solutions are found for the generalized phase algebra, corresponding (up to an overall sign), in effect, to the use of +- e 7 as imaginary unit in each of four superselection sectors. Operators linear over these alternative forms of imanary unit provide distinct types of ''lepton--quark'' and ''quark--quark'' transitions. The subgroup in A which leaves expectation values of operators linear over A invariant is its unitary subgroup U(4), and is a realization (explicitly constructed) of the U(4) invariance of the complex scalar product. An embedding of the algebraic Hilbert space into the complex space defined over C(1,e 7 ) is shown to lead to a decomposition into ''lepton and ''quark'' superselection subspaces. The color SU(3) subgroup of G 2 coincides with the SU(3) subgroup of the generalized phase U(4) which leaves the ''lepton'' space invariant. The problem of constructing tensor products is studied, and some remarks are made on observability and the role of nonassociativity

    2008 highlights: (1) Stockpile Stewardship and Complex Transformation - LLNL achieved scientific breakthroughs that explain some of the key 'unknowns' in nuclear weapons performance and are critical to developing the predictive science needed to ensure the safety, reliability, and security of the U.S. nuclear deterrent without nuclear testing. In addition, the National Ignition Facility (NIF) passed 99 percent completion, an LLNL supercomputer simulation won the 2007 Gordon Bell Prize, and a significant fraction of our inventory of special nuclear material was shipped to other sites in support of complex transformation. (2) National and Global Security - Laboratory researchers delivered insights, technologies, and operational capabilities that are helping to ensure national security and global stability. Of particular note, they developed advanced detection instruments that provide increased speed, accuracy, specificity, and resolution for identifying and characterizing biological, chemical, nuclear, and high-explosive threats. (3) Exceptional Science and Technology - The Laboratory continued its tradition of scientific excellence and technical innovation. LLNL scientists made significant contributions to Nobel Prize-winning work on climate change. LLNL also received three R and D 100 awards and six Nanotech 50 awards, and dozens of Laboratory scientists and engineers were recognized with professional awards. These honors provide valuable confirmation that peers and outside experts recognize the quality of our staff and our work. (4) Enhanced Business and Operations - A major thrust under LLNS is to make the Laboratory more efficient and cost competitive. We achieved roughly $75 million in cost savings for support activities through organizational changes, consolidation of services, improved governance structures and work processes, technology upgrades, and systems shared with Los Alamos National Laboratory. We realized nonlabor cost savings of $23 million. Severe

  9. "No admittance except on business" 

    Directory of Open Access Journals (Sweden)

    2011-04-01

     sociologie embarquée », soit s’en dégager radicalement.“No admittance except on business”. Issues in negotiating entry into organisationsThis article has a history. The first reason for wanting to write it was linked to the development in 2007 of a master course in sociology on the conditions associated with being able to enter organisations. To my great surprise, and in spite of my efforts during the preparation of the course, I found few texts which discussed real entry conditions. This article reflects then this disappointment. The second reason concerns repeated observations of the hardening conditions in relation with studies undertaken within organisations, whether in France or the United States. Reports I have received confirm my observations that the field of high risk organisations has become particularly more and more difficult for young researchers or doctoral students to freely organize their work. Paradoxically, whilst more efforts are undertaken so that sociologists (amongst others have access to risk industries, researchers are confronted with conditions that are often rigid and hardly generous. As for the issues themselves that are studied, they are very aligned with the industrials’ own managerial questions. Ethnographic studies by immersion are abandoned in favour of action-research, in form de theses obliged, at the end of the day, to make propositions for improvements and recommendations about management tools. I have a feeling that what is happening in high-risk organisations is also the case for the sociology of organisations in general. In the first part of this article, I propose a partial revue of the way that the sociology of organisations has treated the question of entering into organisations. I will reflect on why there are so few works devoted to this question and on what the consequences may well be for the field itself. Secondly, I will examine the possibilities offered today as well as the efforts to make in order to, either, resolutely

  13. Exceptions to the Stark law: practical considerations for surgeons.

    Science.gov (United States)

    Satiani, Bhagwan

    2006-03-01

    The purpose of this study was to provide an understanding of the applicable legislative exceptions to prohibitions under the Stark law, which governs common legitimate business relationships in surgical practice. Stark I and II prohibits all referrals (and claims) for the provision of designated health services for federal reimbursement if a physician or immediate family member has any financial relationship with the entity. Regardless of intent (unlike the antikickback statute), any financial relationship is illegal unless specifically excepted by statute. These exceptions are relevant to ownership, compensation arrangements, or both. The most important ones relevant to surgeons are as follows: physician service exception (services rendered in an intragroup referral); in-office ancillary services exception (office-based vascular laboratory); the whole hospital exception (ownership interest in a hospital or department); lease exception (conditions that must be met for a lease not to be considered illegal); bona fide employment exception (important to academic medical centers); personal services arrangement exception (vascular laboratory medical directorship); physician incentive plans exception (if volume or value of referrals are an issue); hospital-affiliated group practice exception (physician services billed by a hospital); recruitment arrangement exception (inducements by hospitals to relocate); items/services exception (transcription services purchased from a hospital); fair market value exception (covers services provided to health care entities); indirect compensation arrangements (dealings between a hospital and entity owned by physicians); and academic medical centers exception (new phase II rules broaden the definition of academic medical centers and ease the requirement that practice plans be tax-exempt organizations, among other changes. Although expert legal advice is required for navigation through the maze of Stark laws, it is incumbent on surgeons

  20. Framing charitable donations as exceptional expenses increases giving.

    Sussman, Abigail B; Sharma, Eesha; Alter, Adam L

    2015-06-01

    Many articles have examined the psychological drivers of charitable giving, but little is known about how people mentally budget for charitable gifts. The present research aims to address this gap by investigating how perceptions of donations as exceptional (uncommon and infrequent) rather than ordinary (common and frequent) expenses might affect budgeting for and giving to charity. We provide the first demonstration that exceptional framing of an identical item can directly influence mental budgeting processes, and yield societal benefits. In 5 lab and field experiments, exceptional framing increased charitable behavior, and diminished the extent to which people considered the effect of the donation on their budgets. The current work extends our understanding of mental accounting and budgeting for charitable gifts, and demonstrates practical techniques that enable fundraisers to enhance the perceived exceptionality of donations.

  4. Obama’s Dual Discourse on American Exceptionalism

    Directory of Open Access Journals (Sweden)

    Hrnjaz Miloš

    2015-08-01

    Full Text Available This paper analyses the highly contested concept of American exceptionalism, as described in the speeches of Barak Obama. The authors of the paper use discourse analysis to show that Obama is using the idea of American exceptionalism on two levels: US foreign policy and the US stance towards international law. Our conclusion is that Obama uses an implicit dual discourse in both these fields. Obama favours active US foreign policy, based on soft power instruments and multilateralism. He insists that American exceptionalism does not mean that the US can exempt itself from the norms of international law, however, he does not think the US should always have a very active foreign policy. He makes room for unilateral acting and the use of hard power instruments in foreign policy. He allows for the use of force even if is not in accordance with the norms of international law, when US national interests are threatened.

  5. Exceptional points enhance sensing in an optical microcavity

    Science.gov (United States)

    Chen, Weijian; Kaya Özdemir, Şahin; Zhao, Guangming; Wiersig, Jan; Yang, Lan

    2017-08-01

    Sensors play an important part in many aspects of daily life such as infrared sensors in home security systems, particle sensors for environmental monitoring and motion sensors in mobile phones. High-quality optical microcavities are prime candidates for sensing applications because of their ability to enhance light-matter interactions in a very confined volume. Examples of such devices include mechanical transducers, magnetometers, single-particle absorption spectrometers, and microcavity sensors for sizing single particles and detecting nanometre-scale objects such as single nanoparticles and atomic ions. Traditionally, a very small perturbation near an optical microcavity introduces either a change in the linewidth or a frequency shift or splitting of a resonance that is proportional to the strength of the perturbation. Here we demonstrate an alternative sensing scheme, by which the sensitivity of microcavities can be enhanced when operated at non-Hermitian spectral degeneracies known as exceptional points. In our experiments, we use two nanoscale scatterers to tune a whispering-gallery-mode micro-toroid cavity, in which light propagates along a concave surface by continuous total internal reflection, in a precise and controlled manner to exceptional points. A target nanoscale object that subsequently enters the evanescent field of the cavity perturbs the system from its exceptional point, leading to frequency splitting. Owing to the complex-square-root topology near an exceptional point, this frequency splitting scales as the square root of the perturbation strength and is therefore larger (for sufficiently small perturbations) than the splitting observed in traditional non-exceptional-point sensing schemes. Our demonstration of exceptional-point-enhanced sensitivity paves the way for sensors with unprecedented sensitivity.

  6. Confinement in F4 Exceptional Gauge Group Using Domain Structures

    Science.gov (United States)

    Rafibakhsh, Shahnoosh; Shahlaei, Amir

    2017-03-01

    We calculate the potential between static quarks in the fundamental representation of the F4 exceptional gauge group using domain structures of the thick center vortex model. As non-trivial center elements are absent, the asymptotic string tension is lost while an intermediate linear potential is observed. SU(2) is a subgroup of F4. Investigating the decomposition of the 26 dimensional representation of F4 to the SU(2) representations, might explain what accounts for the intermediate linear potential, in the exceptional groups with no center element.

  13. What Is Nigeria? Unsettling the Myth of Exceptionalism

    Directory of Open Access Journals (Sweden)

    Aghogho Akpome

    2015-01-01

    Full Text Available This article explores perceptions and representations of Nigeria and Nigerians in the popular global imaginary. It analyses selected popular media narratives in order to foreground contradictions and paradoxes in the ways in which the country and people of Nigeria are discursively constructed. By doing so, it interrogates stereotypes of corruption and criminality as well as myths of exceptionalism about Nigeria and Nigerians originating from both within and outside the country. The analysis reveals that the generalised portrayal of Nigeria and Nigerians as exceptional social subjects is characterised by contradictions and inaccuracies in dominant representational practices and cannot be justified by the verifiable empirical information available on the country and its people.

  14. The Dilemma of Democracy: Collusion and the State of Exception

    Directory of Open Access Journals (Sweden)

    Mark McGovern

    2011-12-01

    Full Text Available In what sense might the authoritarian practices and suspension of legal norms as means to combat the supposed threat of “terrorism,” within and by contemporary western democratic states, be understood as a problem of and not for democracy? That question lies at the heart of this article. It will be explored through the theoretical frame offered in the work of Giorgio Agamben on the state of exception and the example of British state collusion in non-state violence in the North of Ireland. The North of Ireland provides a particularly illuminating case study to explore how the state of exception—the suspension of law and of legal norms and the exercise of arbitrary decision—has increasingly become a paradigm of contemporary governance. In so doing it brings into question not only the traditional conceptualization of the “democratic dilemma” of liberal democratic states “confronting terrorism” but also challenge dominant paradigms of transitional justice that generally fail to problematize the liberal democratic order. After outlining Agamben’s understanding of the state of exception the article will chart the development of “exceptional measures” and the creation of a permanent state of emergency in the North, before critically exploring the role of collusion as an aspect of counter-insurgency during the recent conflict. The paper will argue that the normalization of exceptional measures, combined with the need to delimit the explicitness of constitutional provision for the same, provided a context for the emergence of collusion as a paradigm case for the increasing replication of colonial practices into the core activity of the contemporary democratic state.

    Post, Sarah; Tsujimoto, Satoshi; Vinet, Luc

    2012-01-01

    We introduce a family of exactly-solvable two-dimensional Hamiltonians whose wave functions are given in terms of Laguerre and exceptional Jacobi polynomials. The Hamiltonians contain purely quantum terms which vanish in the classical limit leaving only a previously known family of superintegrable systems. Additional, higher-order integrals of motion are constructed from ladder operators for the considered orthogonal polynomials proving the quantum system to be superintegrable. (paper)

  19. Half-maximal supersymmetry from exceptional field theory

    2017-10-15

    We study D ≥ 4-dimensional half-maximal flux backgrounds using exceptional field theory. We define the relevant generalised structures and also find the integrability conditions which give warped half-maximal Minkowski{sub D} and AdS{sub D} vacua. We then show how to obtain consistent truncations of type II / 11-dimensional SUGRA which break half the supersymmetry. Such truncations can be defined on backgrounds admitting exceptional generalised SO(d - 1 - N) structures, where d = 11 - D, and N is the number of vector multiplets obtained in the lower-dimensional theory. Our procedure yields the most general embedding tensors satisfying the linear constraint of half-maximal gauged SUGRA. We use this to prove that all D ≥ 4 half-maximal warped AdS{sub D} and Minkowski{sub D} vacua of type II / 11-dimensional SUGRA admit a consistent truncation keeping only the gravitational supermultiplet. We also show to obtain heterotic double field theory from exceptional field theory and comment on the M-theory / heterotic duality. In five dimensions, we find a new SO(5, N) double field theory with a (6 + N)-dimensional extended space. Its section condition has one solution corresponding to 10-dimensional N = 1 supergravity and another yielding six-dimensional N = (2, 0) SUGRA. (copyright 2017 WILEY-VCH Verlag GmbH and Co.

    In 1976, the discovery of the high grade Deposit at Cluff Lake in the north of the province of Saskatchewan (Canada) opened new prospects in uranium deposits, which in turn quickly led to the discovery of exceptional deposits both in terms of grade (up 10 % in metal uranium) and tonnage (150, 000 tons of metal per deposit and more). Among these deposits are Key Lake, Cigar Lake, Midwest, MacClean, and more recently, Mac Arthur. These discoveries as well as future ones make the north of Saskatchewan the world's greatest and most interesting uranium-producing province. (authors)

    Directory of Open Access Journals (Sweden)

    Luminita DUMITRIU

    2000-12-01

    Full Text Available Finding association rules is mainly based on generating larger and larger frequent set candidates, starting from frequent attributes in the database. The frequent sets can be organised as a part of a lattice of concepts according to the Formal Concept Analysis approach. Since the lattice construction is database contents-dependent, the pseudo-intents (see Formal Concept Analysis are avoided. Association rules between concept intents (closed sets A=>B are partial implication rules, meaning that there is some data supporting A and (not B; fully explaining the data requires finding exceptions for the association rules. The approach applies to Oracle databases, via SQL queries.

  4. Break-glass handling exceptional situations in access control

    CERN Document Server

    Helmut Petritsch describes the first holistic approach to Break-Glass which covers the whole life-cycle: from access control modeling (pre-access), to logging the security-relevant system state during Break-Glass accesses (at-access), and the automated analysis of Break-Glass accesses (post-access). Break-Glass allows users to override security restrictions in exceptional situations. While several Break-Glass models specific to given access control models have already been discussed in research (e.g., extending RBAC with Break-Glass), the author introduces a generic Break-Glass model.

    International Nuclear Information System (INIS)

    Edelen, Dominic G B

    2005-01-01

    The Frobenius theorem was used in Edelen (2003 Class. Quantum Grav. 20 3661) to obtain a general body of results for the immersion of spacetime in flat spaces of higher dimension. This addendum completes those results for the exceptional case of immersions of codimension 1 where the Frobenius theorem need not be applied. Local actions of the Poincare groups SO(2, 3)--T(5) or SO(1, 4) -- T(5) are used to obtain immersions of spacetime of codimension 1 that involve six arbitrary functions of the four immersion parameters and an arbitrary constant. Explicit calculations are given for several cases. (addendum)

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available In this article we show that imitation is not the mechanism behind the observed increase in suicides subsequent to highly publicized celebrity suicides. Instead, we show that most celebrity suicides are exceptional events and because of that have similar effects on the daily suicide rate as other exciting events. This finding suggests that Durkheim was right in rejecting the Tardean hypothesis that imitation is an operative mechanism and provides substantial support for the competing hypothesis that disruptive and/or exciting events (whether favorable or unfavorable induce anomie and with it suicide.

  7. Exceptional Ground Accelerations and Velocities Caused by Earthquakes

    Energy Technology Data Exchange (ETDEWEB)

    Anderson, John

    2008-01-17

    This project aims to understand the characteristics of the free-field strong-motion records that have yielded the 100 largest peak accelerations and the 100 largest peak velocities recorded to date. The peak is defined as the maximum magnitude of the acceleration or velocity vector during the strong shaking. This compilation includes 35 records with peak acceleration greater than gravity, and 41 records with peak velocities greater than 100 cm/s. The results represent an estimated 150,000 instrument-years of strong-motion recordings. The mean horizontal acceleration or velocity, as used for the NGA ground motion models, is typically 0.76 times the magnitude of this vector peak. Accelerations in the top 100 come from earthquakes as small as magnitude 5, while velocities in the top 100 all come from earthquakes with magnitude 6 or larger. Records are dominated by crustal earthquakes with thrust, oblique-thrust, or strike-slip mechanisms. Normal faulting mechanisms in crustal earthquakes constitute under 5% of the records in the databases searched, and an even smaller percentage of the exceptional records. All NEHRP site categories have contributed exceptional records, in proportions similar to the extent that they are represented in the larger database.

  8. Architecting Fault Tolerance with Exception Handling: Verification and Validation

    Institute of Scientific and Technical Information of China (English)

    Patrick H. S. Brito; Rogério de Lemos; Cecília M. F. Rubira; Eliane Martins

    2009-01-01

    When building dependable systems by integrating untrusted software components that were not originally designed to interact with each other, it is likely the occurrence of architectural mismatches related to assumptions in their failure behaviour. These mismatches, if not prevented during system design, have to be tolerated during runtime. This paper presents an architectural abstraction based on exception handling for structuring fault-tolerant software systems.This abstraction comprises several components and connectors that promote an existing untrusted software element into an idealised fault-tolerant architectural element. Moreover, it is considered in the context of a rigorous software development approach based on formal methods for representing the structure and behaviour of the software architecture. The proposed approach relies on a formal specification and verification for analysing exception propagation, and verifying important dependability properties, such as deadlock freedom, and scenarios of architectural reconfiguration. The formal models are automatically generated using model transformation from UML diagrams: component diagram representing the system structure, and sequence diagrams representing the system behaviour. Finally, the formal models are also used for generating unit and integration test cases that are used for assessing the correctness of the source code. The feasibility of the proposed architectural approach was evaluated on an embedded critical case study.

  10. Exceptional points and quantum correlations in precise measurements

    International Nuclear Information System (INIS)

    Thilagam, A

    2012-01-01

    We examine the physical manifestations of exceptional points and passage times in a two-level system which is subjected to quantum measurements and which admits a non-Hermitian description. Using an effective Hamiltonian acting in the two-dimensional space spanned by the evolving initial and final states, the effects of highly precise quantum measurements in which the monitoring device interferes significantly with the evolution dynamics of the monitored two-level system is analyzed. The dynamics of a multipartite system consisting of the two-level system, a source of external potential and the measurement device is examined using correlation measures such as entanglement and non-classical quantum correlations. Results show that the quantum correlations between the monitored (monitoring) systems is considerably decreased (increased) as the measurement precision nears the exceptional point, at which the passage time is half of the measurement duration. The results indicate that the underlying mechanism by which the non-classical correlations of quantum systems are transferred from one subsystem to another may be better revealed via use of geometric approaches. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Quantum physics with non-Hermitian operators’. (paper)

  11. Confrontation Between Judicial Activism and State of Exception

    Directory of Open Access Journals (Sweden)

    Alexandre Pedro Moura D’Almeida

    2017-01-01

    Full Text Available The judiciary has excelled in the international and national scene, reaching role of great importance, thus creating opposition to the legislative and executive powers. The center of gravity of the sovereign power of the state moves toward the judiciary, that happens to have a more active role and controlling of the others powers, but also appears as a great defender of social and fundamental rights causes, seeking to make an effective constitution. Its great public notoriety has attracted great distrust of various sectors of society, especially by the two powers that have an increasing interference. Arises, therefore, a speech that the judiciary would be reversing into a big and uncontrollable power, increasing the suspicion that now it would be living in a real dictatorship of the judiciary through judicial activism. There is a growing concern with the expansion of activism and the role of the judiciary. The purpose of this work is to conceptualize and approach the judicial activism and the state of exception to search and reveal if there is any similarity, to then draw up a possible answer to the concern of forming a dictatorship of the judiciary. The state of exception is one of the rule of law paradoxes, while activism is a political manifestation of the judiciary. The similarity between the institutes appears as appalling in a dynamic expansion of political power of a state institution exercising judicial function, putting in check who would be the sovereign in a rule of law and democratic state.

    2006-11-01

    The first draft of the honey bee genome sequence and improved genetic maps are utilized to analyze a genome displaying 10 times higher levels of recombination (19 cM/Mb) than previously analyzed genomes of higher eukaryotes. The exceptionally high recombination rate is distributed genome-wide, but varies by two orders of magnitude. Analysis of chromosome, sequence, and gene parameters with respect to recombination showed that local recombination rate is associated with distance to the telomere, GC content, and the number of simple repeats as described for low-recombining genomes. Recombination rate does not decrease with chromosome size. On average 5.7 recombination events per chromosome pair per meiosis are found in the honey bee genome. This contrasts with a wide range of taxa that have a uniform recombination frequency of about 1.6 per chromosome pair. The excess of recombination activity does not support a mechanistic role of recombination in stabilizing pairs of homologous chromosome during chromosome pairing. Recombination rate is associated with gene size, suggesting that introns are larger in regions of low recombination and may improve the efficacy of selection in these regions. Very few transposons and no retrotransposons are present in the high-recombining genome. We propose evolutionary explanations for the exceptionally high genome-wide recombination rate.

    2015-01-26

    We present the generalized Scherk-Schwarz reduction ansatz for the full supersymmetric exceptional field theory in terms of group valued twist matrices subject to consistency equations. With this ansatz the field equations precisely reduce to those of lower-dimensional gauged supergravity parametrized by an embedding tensor. We explicitly construct a family of twist matrices as solutions of the consistency equations. They induce gauged supergravities with gauge groups SO(p,q) and CSO(p,q,r). Geometrically, they describe compactifications on internal spaces given by spheres and (warped) hyperboloides H{sup p,q}, thus extending the applicability of generalized Scherk-Schwarz reductions beyond homogeneous spaces. Together with the dictionary that relates exceptional field theory to D=11 and IIB supergravity, respectively, the construction defines an entire new family of consistent truncations of the original theories. These include not only compactifications on spheres of different dimensions (such as AdS{sub 5}×S{sup 5}), but also various hyperboloid compactifications giving rise to a higher-dimensional embedding of supergravities with non-compact and non-semisimple gauge groups.

  15. Characterizing interactions in online social networks during exceptional events

    Nowadays, millions of people interact on a daily basis on online social media like Facebook and Twitter, where they share and discuss information about a wide variety of topics. In this paper, we focus on a specific online social network, Twitter, and we analyze multiple datasets each one consisting of individuals' online activity before, during and after an exceptional event in terms of volume of the communications registered. We consider important events that occurred in different arenas that range from policy to culture or science. For each dataset, the users' online activities are modeled by a multilayer network in which each layer conveys a different kind of interaction, specifically: retweeting, mentioning and replying. This representation allows us to unveil that these distinct types of interaction produce networks with different statistical properties, in particular concerning the degree distribution and the clustering structure. These results suggests that models of online activity cannot discard the information carried by this multilayer representation of the system, and should account for the different processes generated by the different kinds of interactions. Secondly, our analysis unveils the presence of statistical regularities among the different events, suggesting that the non-trivial topological patterns that we observe may represent universal features of the social dynamics on online social networks during exceptional events.

    Strong multiphoton absorption and harmonic generation in organic fluorescent chromophores are, respectively, significant in many fields of research. However, most of fluorescent chromophores fall short of the full potential due to the absence of the combination of such different nonlinear upconversion behaviors. Here, we demonstrate that an exceptional fluorescent stilbene dye could exhibit efficient two- and three-photon absorption under the excitation of femtosecond pulses in solution phase. Benefiting from its biocompatibility and strong excited state absorption behavior, in vitro two-photon bioimaging and superior optical limiting have been exploited, respectively. Simultaneously, the chromophore could generate efficient three-photon excited fluorescence and third-harmonic generation (THG) when dispersed into PMMA film, circumventing the limitations of classical fluorescent chromophores. Such chromophore may find application in the production of coherent light sources of higher photon energy. Moreover, the combination of three-photon excited fluorescence and THG can be used in tandem to provide complementary information in biomedical studies.

    Research to understand variability at the highest end of the cognitive performance distribution has been scarce. Our aim was to define a cognitive endophenotype based on exceptional episodic memory (EM) performance and to investigate familial aggregation of EM in families from the Long Life Family...... Study (LLFS). Using a sample of 1911 nondemented offspring of long-lived probands, we created a quantitative phenotype, EM (memory z ≥ 1.5), and classified LLFS families as EM and non-EM families based on the number of EM offspring. We then assessed differences in memory performance between LLFS...... = 1.4 × 10(-4)). We demonstrated that there is a familial correlation of the EM endophenotype, suggesting that genetic variants might influence memory performance in long-lived families....

  2. EXCEPTIONAL POINTS IN OPEN AND PT-SYMMETRIC SYSTEMS

    2014-04-01

    Full Text Available Exceptional points (EPs determine the dynamics of open quantum systems and cause also PT symmetry breaking in PT symmetric systems. From a mathematical point of view, this is caused by the fact that the phases of the wavefunctions (eigenfunctions of a non-Hermitian Hamiltonian relative to one another are not rigid when an EP is approached. The system is therefore able to align with the environment to which it is coupled and, consequently, rigorous changes of the system properties may occur. We compare analytically as well as numerically the eigenvalues and eigenfunctions of a 2 × 2 matrix that is characteristic either of open quantum systems at high level density or of PT symmetric optical lattices. In both cases, the results show clearly the influence of the environment on the system in the neighborhood of EPs. Although the systems are very different from one another, the eigenvalues and eigenfunctions indicate the same characteristic features.

    2017-05-29

    We present a general theory of spontaneous emission at exceptional points (EPs)-exotic degeneracies in non-Hermitian systems. Our theory extends beyond spontaneous emission to any light-matter interaction described by the local density of states (e.g., absorption, thermal emission, and nonlinear frequency conversion). Whereas traditional spontaneous-emission theories imply infinite enhancement factors at EPs, we derive finite bounds on the enhancement, proving maximum enhancement of 4 in passive systems with second-order EPs and significantly larger enhancements (exceeding 400×) in gain-aided and higher-order EP systems. In contrast to non-degenerate resonances, which are typically associated with Lorentzian emission curves in systems with low losses, EPs are associated with non-Lorentzian lineshapes, leading to enhancements that scale nonlinearly with the resonance quality factor. Our theory can be applied to dispersive media, with proper normalization of the resonant modes.

  4. The savant syndrome: intellectual impairment and exceptional skill.

    Miller, L K

    1999-01-01

    Occasionally, people with developmental disability display skills at a level inconsistent with their general intellectual functioning, so-called "savant" behavior. Studies of savant behavior are reviewed to determine their relevance to notions about the importance of general intellective functions in the development of exceptional skill. It is concluded that (a) the skill exhibited by savants shares many characteristics with that in people without disability, (b) the skill is usually accompanied by normative levels of performance on at least some subtests of standardized measures of cognitive achievement, and (c) it is unclear whether savants have distinctive cognitive strengths or motivational dispositions, though their relative prevalence among people with certain kinds of disability suggests predisposing constraints. The author proposes that these skills typically reflect highly elaborated preconceptual representational systems.

    Magnon-polaritons are hybrid light-matter quasiparticles originating from the strong coupling between magnons and photons. They have emerged as a potential candidate for implementing quantum transducers and memories. Owing to the dampings of both photons and magnons, the polaritons have limited lifetimes. However, stationary magnon-polariton states can be reached by a dynamical balance between pumping and losses, so the intrinsically nonequilibrium system may be described by a non-Hermitian Hamiltonian. Here we design a tunable cavity quantum electrodynamics system with a small ferromagnetic sphere in a microwave cavity and engineer the dissipations of photons and magnons to create cavity magnon-polaritons which have non-Hermitian spectral degeneracies. By tuning the magnon-photon coupling strength, we observe the polaritonic coherent perfect absorption and demonstrate the phase transition at the exceptional point. Our experiment offers a novel macroscopic quantum platform to explore the non-Hermitian physics of the cavity magnon-polaritons.

  8. The exceptional ethics of the investigator-subject relationship.

    Science.gov (United States)

    Sachs, Benjamin

    2010-02-01

    This article concerns the validity of six canonical rules that institutional review boards use to constrain the behavior of investigators. These rules require investigators to design their studies in a scientifically valid way, not pay their subjects to take risks, minimize risks to their subjects, secure for their subjects access to effective interventions post-trial, not pay their subjects too much and allow their subjects to withdraw from the study unconditionally. Enforcement of these rules is problematic because there are other relationships that seem to be like the investigator-subject relationship in all ethically relevant respects, such as the employer-employee and volunteer organizer-volunteer relationships, to which we would not dream of applying these same rules. Applying these rules in one context but not the others is a violation of ethical consistency I label "exceptionalism." We should conclude that it is time to reexamine the validity of the six rules.

    Full Text Available Household has an extremely important place in the division of income for the economies. It plays a decisive role in personal consumption, investment, and savings. This study aims to identify the determinants of household savings except for income. In this study, "Household Budget Survey" conducted by Turkish Statistical Institute for the years 2002-2013 is used. Survey data has been analyzed by logistic regression models. The results of the study show that house ownership, having an extra house, having annual disposable income of over 10.000 ₺, education level also have a positive effect on household savings. On the other hand, the number of family members, car ownership, temporary or seasonal employment, and living in rural areas affect household savings in a negative way.

  10. Exceptional preservation of Miocene pollen: plasmolysis captured in salt?

    Durska, W.

    2016-07-01

    Exceptionally well-preserved Miocene pollen from the Bochnia salt mine of southern Poland is reported herein. The halite deposits within the salt mine belonging to Late Badenian (Miocene) marine evaporites originated in the Paratethys. Rounded and angular structures are present inside pollen grains. On the basis of the similarity with plasmolyzed pollen grains of modern plants, these structures are considered to represent cytoplasms plasmolyzed in the condensed brine prior to fossilization. Two forms of plasmolyzed cytoplasms (concave and convex) can be observed in modern pollen. Both are distinguished in the investigated fossil material. In porate and colporate grains the shape of the plasmolyzed cellular content is concave while in inaperturate it is convex. The plasmolysis form depends on the type of apertures and pollen shape. The percentage of pollen with fossilized cytoplasms within individual taxa is a valuable environmental indicator, as it depends on the proximity of the pollen-producing plant assemblages to the depositional setting.

  11. A Short-Range Distance Sensor with Exceptional Linearity

    Science.gov (United States)

    Simmons, Steven; Youngquist, Robert

    2013-01-01

    A sensor has been demonstrated that can measure distance over a total range of about 300 microns to an accuracy of about 0.1 nm (resolution of about 0.01 nm). This represents an exceptionally large dynamic range of operation - over 1,000,000. The sensor is optical in nature, and requires the attachment of a mirror to the object whose distance is being measured. This work resulted from actively developing a white light interferometric system to be used to measure the depths of defects in the Space Shuttle Orbiter windows. The concept was then applied to measuring distance. The concept later expanded to include spectrometer calibration. In summary, broadband (i.e., white) light is launched into a Michelson interferometer, one mirror of which is fixed and one of which is attached to the object whose distance is to be measured. The light emerging from the interferometer has traveled one of two distances: either the distance to the fixed mirror and back, or the distance to the moving mirror and back. These two light beams mix and produce an interference pattern where some wavelengths interfere constructively and some destructively. Sending this light into a spectrometer allows this interference pattern to be analyzed, yielding the net distance difference between the two paths. The unique feature of this distance sensor is its ability to measure accurately distance over a dynamic range of more than one million, the ratio of its range (about 300 microns) to its accuracy (about 0.1 nanometer). Such a large linear operating range is rare and arises here because both amplitude and phase-matching algorithms contribute to the performance. The sensor is limited by the need to attach a mirror of some kind to the object being tracked, and by the fairly small total range, but the exceptional dynamic range should make it of interest.

  12. Phase diagrams of exceptional and supersymmetric lattice gauge theories

    Wellegehausen, Bjoern-Hendrik

    2012-07-10

    In this work different strongly-coupled gauge theories with and without fundamental matter have been studied on the lattice with an emphasis on the confinement problem and the QCD phase diagram at nonvanishing net baryon density as well as on possible supersymmetric extensions of the standard model of particle physics. In gauge theories with a non-trivial centre symmetry, as for instance SU(3)-Yang-Mills theory, confinement is intimately related to the centre of the gauge group, and the Polyakov loop serves as an order parameter for confinement. In QCD, this centre symmetry is explicitly broken by quarks in the fundamental representation of the gauge group. But still quarks and gluons are confined in mesons, baryons and glueballs at low temperatures and small densities, suggesting that centre symmetry is not responsible for the phenomenon of confinement. Therefore it is interesting to study pure gauge theories without centre symmetry. In this work this has been done by replacing the gauge group SU(3) of the strong interaction with the exceptional Lie group G{sub 2}, that has a trivial centre. To investigate G{sub 2} gauge theory on the lattice, a new and highly efficient update algorithm has been developed, based on a local HMC algorithm. Employing this algorithm, the proposed and already investigated first order phase transition from a confined to a deconfined phase has been confirmed, showing that indeed a first order phase transition without symmetry breaking or an order parameter is possible. In this context, also the deconfinement phase transition of the exceptional Lie groups F4 and E6 in three spacetime dimensions has been studied. It has been shown that both theories also possess a first order phase transition.

    2013-11-23

    Bangladesh, the eighth most populous country in the world with about 153 million people, has recently been applauded as an exceptional health performer. In the first paper in this Series, we present evidence to show that Bangladesh has achieved substantial health advances, but the country's success cannot be captured simplistically because health in Bangladesh has the paradox of steep and sustained reductions in birth rate and mortality alongside continued burdens of morbidity. Exceptional performance might be attributed to a pluralistic health system that has many stakeholders pursuing women-centred, gender-equity-oriented, highly focused health programmes in family planning, immunisation, oral rehydration therapy, maternal and child health, tuberculosis, vitamin A supplementation, and other activities, through the work of widely deployed community health workers reaching all households. Government and non-governmental organisations have pioneered many innovations that have been scaled up nationally. However, these remarkable achievements in equity and coverage are counterbalanced by the persistence of child and maternal malnutrition and the low use of maternity-related services. The Bangladesh paradox shows the net outcome of successful direct health action in both positive and negative social determinants of health--ie, positives such as women's empowerment, widespread education, and mitigation of the effect of natural disasters; and negatives such as low gross domestic product, pervasive poverty, and the persistence of income inequality. Bangladesh offers lessons such as how gender equity can improve health outcomes, how health innovations can be scaled up, and how direct health interventions can partly overcome socioeconomic constraints.

  16. Gambling and gambling policy in Norway--an exceptional case.

    Science.gov (United States)

    Rossow, Ingeborg; Bang Hansen, Marianne

    2016-04-01

    The aim of this paper is to provide an overview of the development and current status of gambling and gambling policy in Norway. An overview of the research literature and official documents and websites. Gambling on electronic gaming machines (EGMs) increased dramatically in the 1990s in response to technological development and liberalization of gambling policy. Restrictions on availability of EGM gambling occurred from 2006 to 2009 and included a ban on note acceptors, a temporary ban on EGMs and re-introduction of fewer and less aggressive machines under a state monopoly. The restrictions led to significant decreases in total gambling turnover, and several studies suggest that they led to fewer gambling and gambling problems. Various factors may explain why the restrictions were politically feasible. These include media coverage of gambling concerns and economic compensation for revenue losses under the monopoly. In an international context of deregulation of gambling markets, the Norwegian policy restrictions on gambling availability have represented an exceptional case and provide a rare opportunity to explore the outcomes of such regulations. Overall, studies suggest that the policy restrictions have led to reductions in gambling expenditures and problem gambling. © 2015 Society for the Study of Addiction.

  17. Security risks in nuclear waste management: Exceptionalism, opaqueness and vulnerability.

    Science.gov (United States)

    Vander Beken, Tom; Dorn, Nicholas; Van Daele, Stijn

    2010-01-01

    This paper analyses some potential security risks, concerning terrorism or more mundane forms of crime, such as fraud, in management of nuclear waste using a PEST scan (of political, economic, social and technical issues) and some insights of criminologists on crime prevention. Nuclear waste arises as spent fuel from ongoing energy generation or other nuclear operations, operational contamination or emissions, and decommissioning of obsolescent facilities. In international and EU political contexts, nuclear waste management is a sensitive issue, regulated specifically as part of the nuclear industry as well as in terms of hazardous waste policies. The industry involves state, commercial and mixed public-private bodies. The social and cultural dimensions--risk, uncertainty, and future generations--resonate more deeply here than in any other aspect of waste management. The paper argues that certain tendencies in regulation of the industry, claimed to be justified on security grounds, are decreasing transparency and veracity of reporting, opening up invisible spaces for management frauds, and in doing allowing a culture of impunity in which more serious criminal or terrorist risks could arise. What is needed is analysis of this 'exceptional' industry in terms of the normal cannons of risk assessment - a task that this paper begins. Copyright 2009 Elsevier Ltd. All rights reserved.

However, only few electrolytes can simultaneously fulfill these two requisites. Here we report that an oligomeric ionic liquid such as IL4 TFSI with four imidazolium ion units in its structure provides a wide electrochemical window of ∼5.0 V, similar to monomeric ionic liquids. Furthermore, electrochemical impedance measurements using Au working electrodes demonstrated that IL4 TFSI exhibits an exceptionally high EDL capacitance of ∼66 μF/cm 2 , which is ∼6 times as high as those of monomeric ionic liquids so far reported. We also found that an EDL-based field effect transistor (FET) using IL4 TFSI as a gate dielectric material and SrTiO 3 as a channel material displays a very sharp transfer curve with an enhanced carrier accumulation capability of ∼64 μF/cm 2 , as determined by Hall-effect measurements.

  19. Taxonomic and chemical assessment of exceptionally abundant rock mine biofilm

    Full Text Available Background An exceptionally thick biofilm covers walls of ancient gold and arsenic Złoty Stok mine (Poland in the apparent absence of organic sources of energy. Methods and Results We have characterized this microbial community using culture-dependent and independent methods. We sequenced amplicons of the 16S rRNA gene obtained using generic primers and additional primers targeted at Archaea and Actinobacteria separately. Also, we have cultured numerous isolates from the biofilm on different media under aerobic and anaerobic conditions. We discovered very high biodiversity, and no single taxonomic group was dominant. The majority of almost 4,000 OTUs were classified above genus level indicating presence of novel species. Elemental analysis, performed using SEM-EDS and X-ray, of biofilm samples showed that carbon, sulphur and oxygen were not evenly distributed in the biofilm and that their presence is highly correlated. However, the distribution of arsenic and iron was more flat, and numerous intrusions of elemental silver and platinum were noted, indicating that microorganisms play a key role in releasing these elements from the rock. Conclusions Altogether, the picture obtained throughout this study shows a very rich, complex and interdependent system of rock biofilm. The chemical heterogeneity of biofilm is a likely explanation as to why this oligotrophic environment is capable of supporting such high microbial diversity.

    In this work, we analyse Jovian Trojans in the space of suitable resonant elements and we identify clusters of possible collisional origin by two independent methods: the hierarchical clustering and a so-called randombox. Compared to our previous work, we study a twice larger sample. Apart from Eurybates, Ennomos and 1996 RJ families, we have found three more clusters - namely families around asteroids (20961) Arkesilaos, (624) Hektor in the L4 libration zone and (247341) 2001 UV209 in L5. The families fulfill our stringent criteria, I.e. a high statistical significance, an albedo homogeneity and a steeper size-frequency distribution than that of background. In order to understand their nature, we simulate their long term collisional evolution with the Boulder code and dynamical evolution using a modified SWIFT integrator. Within the framework of our evolutionary model, we were able to constrain the age of the Hektor family to be either 1-4 Gyr or, less likely, 0.1-2.5 Gyr, depending on initial impact geometry. Since (624) Hektor itself seems to be a bilobed-shape body with a satellite, I.e. an exceptional object, we address its association with the D-type family and we demonstrate that the moon and family could be created during a single impact event. We simulated the cratering event using a smoothed particle hydrodynamics. This is also the first case of a family associated with a D-type parent body.

  1. Exceptional know how? Possible pitfalls of routinising genetic services.

    Science.gov (United States)

    Schmitz, Dagmar

    2010-09-01

    Genetic testing practices are increasingly advancing clinical medicine. This process of 'routinisation of genetics' has been conceived as a medical and ethical problem mainly because of the assumption that non-geneticists might lack the necessary skills to provide these services. In particular, the relevant theoretical knowledge in clinical genetics is viewed as insufficient in general practitioners and physicians from other specialities. Empirical findings seem to indicate significant variations not only in theoretical but also in practical knowledge between geneticists and non-geneticists. Several fields of practical knowledge-regarding for example the focus of clinical action, the relevance of therapeutic action or the normative framework-can be identified that are or could be areas of conflict when the routinisation of genetic services proceeds. From an ethical point of view, these variations in know how and background are especially relevant whenever the respective genetic service is concerned with medical information of exceptional normative quality, such as, for example, in prenatal genetic screening and diagnosis of untreatable conditions. Here, the clinically acquired practical knowledge of the non-geneticist could be particularly misleading insofar as there is no relation to therapy and-in a narrow sense-no clinical utility to be assessed. Non-geneticists need a chance to acquire the relevant theoretical and practical knowledge in order to understand and fulfil their own duties in the respective situations in a way that secures the important rights at stake of their patients and clients.

  2. Petro-Canada 2002 annual report : profitability and exceptional growth

    International Nuclear Information System (INIS)

    2003-01-01

    Financial information from Petro-Canada was presented and a review of their 2002 operations was made available for the benefit of shareholders. Petro-Canada is focused on 5 core businesses: Terra Nova east coast oil, oil sands development at MacKay River, North American natural gas exploration in the foothills, operations in North Africa, and the petroleum downstream sector. Highlights of 2002 for each of these core business areas were presented. In general, the report states that 2002 was an exceptional year with an operating performance that combined with favourable commodity prices to produce excellent financial results. The most significant event in 2002 was the acquisition and integration of the upstream businesses of Veba Oil and Gas, creating a new core international business for Petro-Canada. This report summarized the company's energy resource activities and presented an operations review as well as consolidated financial statements, and common share information including the accounts of Petro-Canada and its subsidiaries and the company's proportionate share of assets, liabilities, revenues, expenses and cash flows of joint ventures. Revenue and expenditure statements were summarized by source. tabs., figs

  3. Allometry indicates giant eyes of giant squid are not exceptional.

    The eyes of giant and colossal squid are among the largest eyes in the history of life. It was recently proposed that sperm whale predation is the main driver of eye size evolution in giant squid, on the basis of an optical model that suggested optimal performance in detecting large luminous visual targets such as whales in the deep sea. However, it is poorly understood how the eye size of giant and colossal squid compares to that of other aquatic organisms when scaling effects are considered. We performed a large-scale comparative study that included 87 squid species and 237 species of acanthomorph fish. While squid have larger eyes than most acanthomorphs, a comparison of relative eye size among squid suggests that giant and colossal squid do not have unusually large eyes. After revising constants used in a previous model we found that large eyes perform equally well in detecting point targets and large luminous targets in the deep sea. The eyes of giant and colossal squid do not appear exceptionally large when allometric effects are considered. It is probable that the giant eyes of giant squid result from a phylogenetically conserved developmental pattern manifested in very large animals. Whatever the cause of large eyes, they appear to have several advantages for vision in the reduced light of the deep mesopelagic zone.

  4. Exceptional deliveries: home births as ethical anomalies in American obstetrics.

    Science.gov (United States)

    Wendland, Claire L

    2013-01-01

    Interest in home birth appears to be growing among American women, and most obstetricians can expect to encounter patients who are considering home birth. In 2011, the American College of Obstetricians and Gynecologists (ACOG) issued an opinion statement intended to guide obstetricians in responding to such patients. In this article, I examine the ACOG statement in light of the historical and contemporary clinical realities surrounding home birth in the United States, an examination guided in part by my own experiences as an obstetrician in home-birth-friendly and home-birth-unfriendly medical milieus. Comparison with other guidelines indicates that ACOG treats home birth as an ethical exception: comparable evidence leads to strikingly different recommendations in the case of home birth and the case of trial of labor following a prior cesarean; and ACOG treats other controversial issues that involve similar ethical questions quite differently. By casting the provision of information as not just the primary but the sole ethical responsibility of the obstetrician, ACOG statement obviates obstetricians' responsibilities to provide appropriate clinical care and to make the safest possible clinical environment for those mothers who choose home birth and for their newborns. What, on its face, seems to be a statement of respect for women's autonomy, implicitly authorizes behaviors that unethically restrain truly autonomous choices. Obstetricians need not attend home births, I argue. Our ethical duties do, however, oblige us (1) to refer clients to skilled clinicians who will attend home birth, (2) to continue respectful antenatal care for those women choosing home birth, (3) to provide appropriate consultation to home birth attendants, and (4) to ensure that transfers of care are smooth and nonpunitive.

  5. Surface chemical modification for exceptional wear life of MEMS materials

    Directory of Open Access Journals (Sweden)

    R. Arvind Singh

    2011-12-01

    Full Text Available Micro-Electro-Mechanical-Systems (MEMS are built at micro/nano-scales. At these scales, the interfacial forces are extremely strong. These forces adversely affect the smooth operation and cause wear resulting in the drastic reduction in wear life (useful operating lifetime of actuator-based devices. In this paper, we present a surface chemical modification method that reduces friction and significantly extends the wear life of the two most popular MEMS structural materials namely, silicon and SU-8 polymer. The method includes surface chemical treatment using ethanolamine-sodium phosphate buffer, followed by coating of perfluoropolyether (PFPE nanolubricant on (i silicon coated with SU-8 thin films (500 nm and (ii MEMS process treated SU-8 thick films (50 μm. After the surface chemical modification, it was observed that the steady-state coefficient of friction of the materials reduced by 4 to 5 times and simultaneously their wear durability increased by more than three orders of magnitude (> 1000 times. The significant reduction in the friction coefficients is due to the lubrication effect of PFPE nanolubricant, while the exceptional increase in their wear life is attributed to the bonding between the -OH functional group of ethanolamine treated SU-8 thin/thick films and the -OH functional group of PFPE. The surface chemical modification method acts as a common route to enhance the performance of both silicon and SU-8 polymer. It is time-effective (process time ≤ 11 min, cost-effective and can be readily integrated into MEMS fabrication/assembly processes. It can also work for any kind of structural material from which the miniaturized devices are/can be made.

  6. Scintigraphic and radiologic aspects of two exceptional tumors at knee

    Lescout, J.M.; Bussy, E.; Tourrette, J.H.; Dussau, J.P.; Gadea, J.; Camelli, M.

    1997-01-01

    We present two cases of rare vascular tumors of knee which in the frame of the pre-surgery extension examination were successfully explored by the Osseous Scintigraphy (OS) and Magnetic Resonance Imagery (MRI). The first case was a young girl 17 years old accusing since two years a mechanical pain in the left knee, without radiographic or biologic anomalies. Early profile incidence of OS indicates an articular hyperemia of geometrical shape which later disappeared totally, what evoked the absence of osteoblastic activity of a hyper-vascularized lesion. The MRI showed the existence of an extraosseous tumor in the retro-patellar loge. The histologic analysis led to the diagnosis of synovial hemangioma, a rare benign tumor which benefited by a complete extirpation followed by rapid remission of walking. The second case was a male 53 years old which presented a painful right sub-patellar tumefaction with a major osteolysis of 1/3 upper tibia, by standard radiography. The OS in two phases indicated a unique hyper-vascularized very active osseous affliction. The MRI has confirmed the well circumscribed afflicted zone of the tibia's proximal metaphysis and showed an invasion of the soft parts. The pathologist concluded on a epithelial hemangioma-endothelioma, a vascular tumor of intermediate malignity which benefited by an extirpation with osseous graft showing no negative evolution after one year. In the vast frame of the skeletal tumors these exceptional vascular peri-articular afflictions allow illustrating the complementarity of OS and MRI which give to the surgery all the information useful for their extension on their more or less vascularized character and on their osteoblastic component

  7. Global diversity of marine isopods (except Asellota and crustacean symbionts.

    Directory of Open Access Journals (Sweden)

    Gary C B Poore

    Full Text Available The crustacean order Isopoda (excluding Asellota, crustacean symbionts and freshwater taxa comprise 3154 described marine species in 379 genera in 37 families according to the WoRMS catalogue. The history of taxonomic discovery over the last two centuries is reviewed. Although a well defined order with the Peracarida, their relationship to other orders is not yet resolved but systematics of the major subordinal taxa is relatively well understood. Isopods range in size from less than 1 mm to Bathynomus giganteus at 365 mm long. They inhabit all marine habitats down to 7280 m depth but with few doubtful exceptions species have restricted biogeographic and bathymetric ranges. Four feeding categories are recognised as much on the basis of anecdotal evidence as hard data: detritus feeders and browsers, carnivores, parasites, and filter feeders. Notable among these are the Cymothooidea that range from predators and scavengers to external blood-sucking micropredators and parasites. Isopods brood 10-1600 eggs depending on individual species. Strong sexual dimorphism is characteristic of several families, notably in Gnathiidae where sessile males live with a harem of females while juvenile praniza stages are ectoparasites of fish. Protandry is known in Cymothoidae and protogyny in Anthuroidea. Some Paranthuridae are neotenous. About half of all coastal, shelf and upper bathyal species have been recorded in the MEOW temperate realms, 40% in tropical regions and the remainder in polar seas. The greatest concentration of temperate species is in Australasia; more have been recorded from temperate North Pacific than the North Atlantic. Of tropical regions, the Central Indo-Pacific is home to more species any other region. Isopods are decidedly asymmetrical latitudinally with 1.35 times as many species in temperate Southern Hemisphere than the temperate North Atlantic and northern Pacific, and almost four times as many Antarctic as Arctic species. More species

  13. An Exploitability Analysis Technique for Binary Vulnerability Based on Automatic Exception Suppression

    Directory of Open Access Journals (Sweden)

    Zhiyuan Jiang

    2018-01-01

    Full Text Available To quickly verify and fix vulnerabilities, it is necessary to judge the exploitability of the massive crash generated by the automated vulnerability mining tool. While the current manual analysis of the crash process is inefficient and time-consuming, the existing automated tools can only handle execute exceptions and some write exceptions but cannot handle common read exceptions. To address this problem, we propose a method of determining the exploitability based on the exception type suppression. This method enables the program to continue to execute until an exploitable exception is triggered. The method performs a symbolic replay of the crash sample, constructing and reusing data gadget, to bypass the complex exception, thereby improving the efficiency and accuracy of vulnerability exploitability analysis. The testing of typical CGC/RHG binary software shows that this method can automatically convert a crash that cannot be judged by existing analysis tools into a different crash type and judge the exploitability successfully.

  18. Exceptional indices

    Science.gov (United States)

    Gaiotto, Davide; Razamat, Shlomo S.

    2012-05-01

    Recently a prescription to compute the superconformal index for all theories of class S was proposed. In this paper we discuss some of the physical information which can be extracted from this index. We derive a simple criterion for the given theory of class S to have a decoupled free component and for it to have enhanced flavor symmetry. Furthermore, we establish a criterion for the "good", the "bad", and the "ugly" trichotomy of the theories. After interpreting the prescription to compute the index with non-maximal flavor symmetry as a residue calculus we address the computation of the index of the bad theories. In particular we suggest explicit expressions for the superconformal index of higher rank theories with E n flavor symmetry, i.e. for the Hilbert series of the multi- instanton moduli space of E n .

    Highlights: •Event detection and exception handling is integrated in control system architecture. •Pulse control with local exception handling and pulse supervision with central exception handling are strictly separated. •Local exception handling limits the effect of an exception to a minimal part of the controlled system. •Central Exception Handling solves problems requiring coordinated action of multiple control components. -- Abstract: Thermonuclear plasmas are governed by nonlinear characteristics: plasma operation can be classified into scenarios with pronounced features like L and H-mode, ELMs or MHD activity. Transitions between them may be treated as events. Similarly, technical systems are also subject to events such as failure of measurement sensors, actuator saturation or violation of machine and plant operation limits. Such situations often are handled with a mixture of pulse abortion and iteratively improved pulse schedule reference programming. In case of protection-relevant events, however, the complexity of even a medium-sized device as ASDEX Upgrade requires a sophisticated and coordinated shutdown procedure rather than a simple stop of the pulse. The detection of events and their intelligent handling by the control system has been shown to be valuable also in terms of saving experiment time and cost. This paper outlines how ASDEX Upgrade's discharge control system (DCS) detects events and handles exceptions in two stages: locally and centrally. The goal of local exception handling is to limit the effect of an unexpected or asynchronous event to a minimal part of the controlled system. Thus, local exception handling facilitates robustness to failures but keeps the decision structures lean.

    There is a growing interest in the logical possibility that exceptional mathematical structures (exceptional Lie and super Lie algebras, the exceptional Jordan algebra, etc.) could be linked to an ultimate 'exceptional' formulation for a Theory Of Everything (TOE). The maximal division algebra of the octonions can be held as the mathematical responsible for the existence of the exceptional structures mentioned above. In this context it is quite motivating to systematically investigate the properties of octonionic spinors and the octonionic realizations of supersymmetry. In particular the M-algebra can be consistently defined for two structures only, a real structure, leading to the standard M-algebra, and an octonionic structure. The octonionic version of the M-algebra admits striking properties induced by octonionic p-forms identities. (author)

  17. Center variation in the use of nonstandardized model for end-stage liver disease exception points.

    2013-12-01

    The Model for End-Stage Liver Disease (MELD) score is an imperfect prognosticator of waitlist dropout, so transplant centers may apply for exception points to increase a waitlist candidate's priority on the waitlist. Exception applications are categorized as recognized exceptional diagnoses (REDs; eg, hepatocellular carcinoma) and non-REDs (eg, cholangitis). Although prior work has demonstrated regional variation in the use of exceptions, no work has examined the between-center variability. We analyzed all new waitlist candidates from February 27, 2002 to June 3, 2011 to explore variations in the use of non-REDs, for which no strict exception criteria exist. There were 58,641 new waitlist candidates, and 4356 (7.4%) applied for a non-RED exception. The number of applications increased steadily over time, as did the approval rates for such applications: from variation to ensure the appropriate and equitable use of non-RED exceptions. © 2013 American Association for the Study of Liver Diseases.

  18. Fingerprints of exceptional points in the survival probability of resonances in atomic spectra

    The unique time signature of the survival probability exactly at the exceptional point parameters is studied here for the hydrogen atom in strong static magnetic and electric fields. We show that indeed the survival probability S(t)=| | 2 decays exactly as |1-at| 2 e -Γ EP t/(ℎ/2π) , where Γ EP is associated with the decay rate at the exceptional point and a is a complex constant depending solely on the initial wave packet that populates exclusively the two almost degenerate states of the non-Hermitian Hamiltonian. This may open the possibility for a first experimental detection of exceptional points in a quantum system.

    Zhong, Q.; Christodoulides, D. N.; Khajavikhan, M.; Makris, K. G.; El-Ganainy, R.

    2018-02-01

    We investigate the extreme dynamics of non-Hermitian systems near higher-order exceptional points in photonic networks constructed using the bosonic algebra method. We show that strong power oscillations for certain initial conditions can occur as a result of the peculiar eigenspace geometry and its dimensionality collapse near these singularities. By using complementary numerical and analytical approaches, we show that, in the parity-time (PT ) phase near exceptional points, the logarithm of the maximum optical power amplification scales linearly with the order of the exceptional point. We focus in our discussion on photonic systems, but we note that our results apply to other physical systems as well.

  1. Pair of Exceptional Points in a Microdisk Cavity under an Extremely Weak Deformation

    Science.gov (United States)

    Yi, Chang-Hwan; Kullig, Julius; Wiersig, Jan

    2018-03-01

    One of the interesting features of open quantum and wave systems is the non-Hermitian degeneracy called an exceptional point, where not only energy levels but also the corresponding eigenstates coalesce. We demonstrate that such a degeneracy can appear in optical microdisk cavities by deforming the boundary extremely weakly. This surprising finding is explained by a semiclassical theory of dynamical tunneling. It is shown that the exceptional points come in nearly degenerated pairs, originating from the different symmetry classes of modes. A spatially local chirality of modes at the exceptional point is related to vortex structures of the Poynting vector.

  4. SUBSTANTIAL EXCEPTIONS AND (DELIMITATIONS OF THE POWERS OF THE JUDGES ON CIVIL PROCEDURAL LAW

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available This essay aims to unveil the role of the substantial exceptions on delimiting the powers of the judges on civil procedural law, especially regarding the ex officio judicial activity. This way, under a phenomenological method and based on a vision of guarantee of rights on procedural law, the article offers a brief explanation of the question concerning the content of the object under litigation and its role of (delimiting the powers of the judges. The work hypothesis is the addition of the substantial exceptions among the content of the object under litigation, along with the claim itself and the cause of action. The results lie on the premise that, by the substantial exceptions, the defendant extends the object under litigation – which is formed dynamically on civil procedure. The conclusion points towards the idea that the substantial exceptions act in a way of limiting the ex officio judicial activity on civil procedural law

  11. F4 , E6 and G2 exceptional gauge groups in the vacuum domain structure model

    Science.gov (United States)

    Shahlaei, Amir; Rafibakhsh, Shahnoosh

    2018-03-01

    Using a vacuum domain structure model, we calculate trivial static potentials in various representations of F4 , E6, and G2 exceptional groups by means of the unit center element. Due to the absence of the nontrivial center elements, the potential of every representation is screened at far distances. However, the linear part is observed at intermediate quark separations and is investigated by the decomposition of the exceptional group to its maximal subgroups. Comparing the group factor of the supergroup with the corresponding one obtained from the nontrivial center elements of S U (3 ) subgroup shows that S U (3 ) is not the direct cause of temporary confinement in any of the exceptional groups. However, the trivial potential obtained from the group decomposition into the S U (3 ) subgroup is the same as the potential of the supergroup itself. In addition, any regular or singular decomposition into the S U (2 ) subgroup that produces the Cartan generator with the same elements as h1, in any exceptional group, leads to the linear intermediate potential of the exceptional gauge groups. The other S U (2 ) decompositions with the Cartan generator different from h1 are still able to describe the linear potential if the number of S U (2 ) nontrivial center elements that emerge in the decompositions is the same. As a result, it is the center vortices quantized in terms of nontrivial center elements of the S U (2 ) subgroup that give rise to the intermediate confinement in the static potentials.

  12. Looking for exceptions on knowledge rules induced from HIV cleavage data set

    Directory of Open Access Journals (Sweden)

    Ronaldo Cristiano Prati

    2004-01-01

    Full Text Available The aim of data mining is to find useful knowledge inout of databases. In order to extract such knowledge, several methods can be used, among them machine learning (ML algorithms. In this work we focus on ML algorithms that express the extracted knowledge in a symbolic form, such as rules. This representation may allow us to ''explain'' the data. Rule learning algorithms are mainly designed to induce classification rules that can predict new cases with high accuracy. However, these sorts of rules generally express common sense knowledge, resulting in many interesting and useful rules not being discovered. Furthermore, the domain independent biases, especially those related to the language used to express the induced knowledge, could induce rules that are difficult to understand. Exceptions might be used in order to overcome these drawbacks. Exceptions are defined as rules that contradict common believebeliefs. This kind of rules can play an important role in the process of understanding the underlying data as well as in making critical decisions. By contradicting the user's common beliefves, exceptions are bound to be interesting. This work proposes a method to find exceptions. In order to illustrate the potential of our approach, we apply the method in a real world data set to discover rules and exceptions in the HIV virus protein cleavage process. A good understanding of the process that generates this data plays an important role oin the research of cleavage inhibitors. We consider believe that the proposed approach may help the domain expert to further understand this process.

  13. Minimal unitary realizations of exceptional U-duality groups and their subgroups as quasiconformal groups

    International Nuclear Information System (INIS)

    Gunaydin, Murat; Pavlyk, Oleksandr

    2005-01-01

    We study the minimal unitary representations of noncompact exceptional groups that arise as U-duality groups in extended supergravity theories. First we give the unitary realizations of the exceptional group E 8(-24) in SU*(8) as well as SU(6,2) covariant bases. E 8(-24) has E 7 x SU(2) as its maximal compact subgroup and is the U-duality group of the exceptional supergravity theory in d=3. For the corresponding U-duality group E 8(8) of the maximal supergravity theory the minimal realization was given. The minimal unitary realizations of all the lower rank noncompact exceptional groups can be obtained by truncation of those of E 8(-24) and E 8(8) . By further truncation one can obtain the minimal unitary realizations of all the groups of the 'Magic Triangle'. We give explicitly the minimal unitary realizations of the exceptional subgroups of E 8(-24) as well as other physically interesting subgroups. These minimal unitary realizations correspond, in general, to the quantization of their geometric actions as quasi-conformal groups. (author)

  14. Comparative Study of Unconscionability Exception to the Principle of Autonomy in Law of Letter of Credits

    Directory of Open Access Journals (Sweden)

    Hamed Alavi

    2016-08-01

    Full Text Available This paper touches upon legal nature and scope of unconscionability as an exception to autonomy principle of documentary letters of credit (LC and bank guarantees. Complicated process of international trade is known as the main reason behind development of new exceptions to globally appreciated principle of autonomy in process of LC transaction. Apart from fraud which has been recognized in international business society and various jurisdictions, other exceptions including unconscionability, nullity, illegality and recklessness have received different treatments in different national laws. Unconscionability is applied to situations where beneficiary’s demand to draw under the LC is not fraudulent but affected with bad faith in a way that court prevents bank from honouring the credit. While UCP leaves the problem of fraud and other exceptions to autonomy principle to be solved by national laws, among common law countries, unconscionability defence has been recognized in Australia and Singapore but others do not show welcoming attitude towards it. Current paper tries to find reasons behind different attitudes of common law jurisdictions to unconscionability defence in letter of credit process by answering following questions: What is the nature of unconscionability? How different common law jurisdictions have received it as an exception to principle of autonomy in documentary letters of credit and bank guarantees? And last but not the least, what are arguments in favour and against its universal recognition as a defence for payment under letter of credit and bank guarantee system?

  15. Exceptional longevity and exceptionally high metabolic rates in anthropoid primates are linked to a major modification of the ubiquinone reduction site of cytochrome b.

    Science.gov (United States)

    Rottenberg, Hagai

    2014-10-01

    The maximal lifespan of Anthropoid primates (monkeys, apes and humans) exceed the lifespan of most other mammals of equal body mass. Unexpectedly, their exceptional longevity is associated with exceptionally high metabolic rates, in apparent contradiction to the Free Radical Theory of Aging. It was therefore suggested that in anthropoid primates (and several other taxa of mammals and birds) the mitochondrial electron transport complexes evolved to modify the relationship between basal electron transport and superoxide generation to allow for the evolution of exceptional longevity. Cytochrome b, the core protein of the bc1 complex is a major source of superoxide. The amino-acid sequence of cytochrome b evolved much faster in anthropoid than in prosimian primates, and most other mammals, resulting in a large change in the amino-acids composition of the protein. As a result of these changes cytochrome b in anthropoid primates is significantly less hydrophobic and contains more polar residues than other primates and most other mammals. Most of these changes are clustered around the reduction site of uboiquinone. In particular a key positively charged residue, arginine 313, that interacts with propionate D of heme bH, and thus raises its redox potential, is substituted in anthropoid primates with the neutral residue glutamine, most likely resulting in a lower redox potential of heme bH and faster reduction of ubiquinone at high proton motive force. It is suggested that these changes contribute to the observed increased rates of basal metabolism and reduce the rates of superoxide production, thus allowing for increased lifespan.

    Drawing on 17 months of ethnographic fieldwork in Freetown, Sierra Leone, I highlight the recursive relationship between Sierra Leone as an exemplary setting and HIV as an exceptional disease. Through this relationship, I examine how HIV-positive individuals rely on both enumerative knowledge (seroprevalence rates) and vernacular accounting (NGO narratives of vulnerability) to communicate the uniqueness of their experience as HIV sufferers and to demarcate the boundaries of their status. Various observers' enumerative and vernacular accounts of Sierra Leone's decade-long civil conflict, coupled with global health accounts of HIV as exceptional, reveal the calculus of power through which global health projects operate. The contradictions between the exemplary and the exceptional-and the accompanying tension between quantitative and qualitative facts-are mutually constituted in performances and claims made by HIV-positive individuals themselves.

  17. The Nuclear Installations (Excepted Matter) Regulations 1978 (Statutory Instrument No. 1779, 4 December 1978)

    International Nuclear Information System (INIS)

    1979-01-01

    These Regulations prescribe, for the purposes of the definition of 'excepted matter' in the Nuclear Installations Act 1965, certain specified quantities and forms of nuclear matter, and supersede the Nuclear Installations (excepted Matter) Regulations 1965. They bring the definition of excepted matter in those Regulations into line with the decisions of 27 October 1977 of the OECD Nuclear Energy Agency's Steering Committee excluding certain kinds and quantities of nuclear substances from the scope of the Paris Convention on Third Party Liability in the Field of Nuclear Energy. Compared with the 1965 Regulations, the principal changes in relation to consignments are that activity limits and packing requirements now take account of the most recent IAEA Regulations.

  18. Quality factor enhancement in photonic crystal slabs by manipulation of the ring of exceptional points

    DEFF Research Database (Denmark)

    Kaminski, Piotr Marek; Taghizadeh, Alireza; Breinbjerg, Olav

    2017-01-01

    Presently, we investigate the influence of the extent of a ring of exceptional points on the Q-factor of three-dimensional photonic crystal slabs. By changing the thickness of the slab, the extent of the ring of exceptional points is varied, allowing us to recover the Dirac cones in open, non......-Hermitian systems. In this case, three bound states in the continuum are exhibited close to the Gamma-point. For an optimized thickness of the slab, the associated Q-factors are found to grow rapidly with the size of the slab. The present results may lead to novel, small area and high Q-factor photonic crystal...

  19. Algebraic equations for the exceptional eigenspectrum of the generalized Rabi model

    International Nuclear Information System (INIS)

    Li, Zi-Min; Batchelor, Murray T

    2015-01-01

    We obtain the exceptional part of the eigenspectrum of the generalized Rabi model, also known as the driven Rabi model, in terms of the roots of a set of algebraic equations. This approach provides a product form for the wavefunction components and allows an explicit connection with recent results obtained for the wavefunction in terms of truncated confluent Heun functions. Other approaches are also compared. For particular parameter values the exceptional part of the eigenspectrum consists of doubly degenerate crossing points. We give a proof for the number of roots of the constraint polynomials and discuss the number of crossing points. (paper)

Such parents often benefit from a direct approach to addressing these issues…

  9. Exceptional longevity in female Rottweiler dogs is not encumbered by investment in reproduction.

    2013-12-01

    To better understand the potential trade-off between female reproductive investment and longevity in an emerging model of human healthspan, we studied pet dogs to determine whether intensity of reproduction (total number of offspring) encumbered the likelihood of exceptional longevity. This hypothesis was tested by collecting and analyzing lifetime medical histories, including complete reproductive histories, for a cohort of canine "centenarians"--exceptionally long-lived Rottweiler dogs that lived more than 30% longer than the breed's average life expectancy. Reproductive intensity (number of litters, total number of pups) and tempo of reproductive effort (age at first reproduction, mean interbirth interval, age at last reproduction) in 78 exceptionally long-lived female Rottweilers (>13 years old) were compared to a cohort of 97 female Rottweilers that had usual longevity (age at death 8.0-10.75 years). We found no evidence that a mother's physiological investment in offspring was associated with disadvantaged longevity. Instead, similar to some studies in women, our data showed an inverted U-shaped trend, suggesting that moderate investment in reproduction may promote longevity. Late reproductive success, a much-studied surrogate of maternal fitness in women, was not a strong predictor of longevity in this canine cohort. Instead, independent of reproductive investment, the duration of lifetime ovary exposure was significantly associated with highly successful aging. Our results from exceptionally long-lived pet dogs provide rationale for further investigative efforts to understand the ovary-sensitive biological factors that promote healthy longevity in women and pet dogs.

    2018-02-01

    We demonstrate the generation of chiral modes-vortex flows with fixed handedness in exciton-polariton quantum fluids. The chiral modes arise in the vicinity of exceptional points (non-Hermitian spectral degeneracies) in an optically induced resonator for exciton polaritons. In particular, a vortex is generated by driving two dipole modes of the non-Hermitian ring resonator into degeneracy. Transition through the exceptional point in the space of the system's parameters is enabled by precise manipulation of real and imaginary parts of the closed-wall potential forming the resonator. As the system is driven to the vicinity of the exceptional point, we observe the formation of a vortex state with a fixed orbital angular momentum (topological charge). This method can be extended to generate higher-order orbital angular momentum states through coalescence of multiple non-Hermitian spectral degeneracies. Our Letter demonstrates the possibility of exploiting nontrivial and counterintuitive properties of waves near exceptional points in macroscopic quantum systems.

  17. Selection of exception limits for all actinide nuclides based on revised criteria for safe international transport

    Lavarenne, C.; Rouyer, V.; Sert, G.; Mennerdahl, D.; Dean, C.; Barton, N.; Jean, F.

    2003-01-01

    Since 1998, there have been some speculations about future transport of significant quantities and concentrations of other actinide nuclides than the four currently listed in the regulation for the safe transport of the radioactive material. Therefore, it raised a need to specify exception limits for such actinides. Additionally, the total fissile nuclide mass per consignment of excepted packages was limited in the 1996 edition of the regulations (a conveyance limit is preliminary supported in the 2003 revision). The proposed changes of the rules have to take this new control into account. The European Community (DGTREN) decided to fund a project related to this subject. In order to define credible exception limits, it was necessary to have reasonably accurate data for all actinide nuclides. Then the authors of the study decided to perform calculations with different codes (MONK, MCNP, CRISTAL, SCALE) and different cross-section libraries (JEF2.2, ENDFB, JENDL, etc.). This article presents the work achieved and gives propositions of modification for the IAEA requirements for the Safe Transport of Radioactive Material related to, firstly, the list of the fissile materials, and secondly, the rule to determine the quantities of actinide nuclides that can be excepted from the requirements for the packages containing fissile materials. The participants acknowledge the DGTREN who made this work possible due to its support. (author)

    Adequate real-time event detection and exception handling for machine protection and plasma optimization are important for safe and efficient operation of fusion devices. Within the scope of a layered protection hierarchy, the exception handling goals of the real-time control system are to optimize control performance, switch to alternate investigations, terminate the discharge in a controlled way, or alarm the interlock system when control is lost. Analysis of these goals shows that they can be implemented with two methods: the modification of the reference values to respond to degradation of sensors, actuators or controllers, and the replacement of schedules to perform other investigations, which includes controlled termination and interlock alarm cases. In support of these methods the sensor and evaluated data quality and the time-varying actuator characteristics and capacity must be communicated to users of those information to avoid failure propagation.

  9. The Return of the Cultural Exception and its Impact on International Agreements

    2014-07-01

    Full Text Available This essay examines the influence of the French concept of the “cultural exception” on European media policy and international agreements. After briefly reviewing the historical background of the cultural exception in France, the essay describes how demands for the cultural exception and those for diversity affect inter-/transnational agreements within the European Union and around the world. Special focus is placed on the current secret EU/US Transatlantic Trade and Investment Partnership Agreement (TTIP negotiations that nearly failed because of France’s insistence that media and culture be exempted. The author argues that the concept of the “cultural exception” has been revived in recent years. However, due to the dual character of media (which is both a cultural and economic good, and the lack of a global media policy, the culture and trade debate will continue.

    Basal cell carcinoma (BCC), the most prevalent form of cancer worldwide, is a malignant skin neoplasm. It is locally invasive, with an exceptional incidence of reported metastasis. It can also be part of the Gorlin-Goltz syndrome, an autosomal dominant genetic disorder with high penetrance and variable expressivity, which is principally characterized by cutaneous BCC, odontogenic keratocysts, palmar and/or plantar pits, and falx cerebri calcification. We report the exceptional clinical observation of a 54-year-old man presenting bone metastasis from BCC in Gorlin-Goltz syndrome. Less than 300 cases of metastatic BCC have been reported in the literature. The present case is the second associated with Gorlin-Goltz syndrome. Copyright 2009 S. Karger AG, Basel.

  11. SIMPLE MODELS OF THREE COUPLED PT -SYMMETRIC WAVE GUIDES ALLOWING FOR THIRD-ORDER EXCEPTIONAL POINTS

    2017-12-01

    Full Text Available We study theoretical models of three coupled wave guides with a PT-symmetric distribution of gain and loss. A realistic matrix model is developed in terms of a three-mode expansion. By comparing with a previously postulated matrix model it is shown how parameter ranges with good prospects of finding a third-order exceptional point (EP3 in an experimentally feasible arrangement of semiconductors can be determined. In addition it is demonstrated that continuous distributions of exceptional points, which render the discovery of the EP3 difficult, are not only a feature of extended wave guides but appear also in an idealised model of infinitely thin guides shaped by delta functions.

    Full Text Available Debt assignments have the effect of assigning a new creditor in the legal position of the creditorassignor, i.e. the right to claim, with all its accessories and warranties, in the same legalconditions, enforceable against all exceptions of the assignor, even the personal ones. Thus, theassignee is entitled to invoke the exception of breach of contract/non-performance, where the ratioof obligations originally derived from a mutually binding contract and the contractual partnerrefuses to fulfill the performance that was required. Invocation of exceptio non adimpleticontractus does not result in termination of the legal relationship of obligations, but only to itssuspension as a means to compel the debtor to fulfill the obligation assumed.

    1984-01-01

    Ten-dimensional Yang - Mills gauge theories based on the exceptional groups E 6 and E 8 are reduced to four-dimensional flavour-chiral Yang - Mills - Higgs theories where the extra six dimensions are identified with the compact G 2 /SU(3) and SO(7)/SO(6) coset spaces. A ten-dimensional E 8 theory leads to three families of SU(5), one of which lies in the 144-dimensional representation of SO(10)

  2. Waveguides with Absorbing Boundaries: Nonlinearity Controlled by an Exceptional Point and Solitons

    Science.gov (United States)

    Midya, Bikashkali; Konotop, Vladimir V.

    2017-07-01

    We reveal the existence of continuous families of guided single-mode solitons in planar waveguides with weakly nonlinear active core and absorbing boundaries. Stable propagation of TE and TM-polarized solitons is accompanied by attenuation of all other modes, i.e., the waveguide features properties of conservative and dissipative systems. If the linear spectrum of the waveguide possesses exceptional points, which occurs in the case of TM polarization, an originally focusing (defocusing) material nonlinearity may become effectively defocusing (focusing). This occurs due to the geometric phase of the carried eigenmode when the surface impedance encircles the exceptional point. In its turn, the change of the effective nonlinearity ensures the existence of dark (bright) solitons in spite of focusing (defocusing) Kerr nonlinearity of the core. The existence of an exceptional point can also result in anomalous enhancement of the effective nonlinearity. In terms of practical applications, the nonlinearity of the reported waveguide can be manipulated by controlling the properties of the absorbing cladding.

  3. Understanding the failure of health-care exceptionalism in the Supreme Court's Obamacare decision.

    Science.gov (United States)

    Moncrieff, Abigail R

    2012-09-01

    On June 28, 2012, a mere century after the first presidential proposal for national health insurance, the Supreme Court issued a resounding victory for President Obama and for health-care reform generally, upholding the Patient Protection and Affordable Care Act against a serious constitutional challenge. Nevertheless, the Court also struck a potential blow to future health-care reform efforts in refusing to accept the solicitor general's argument that health care is a unique market with unique regulatory needs that justify special constitutional treatment. The failure of health-care exceptionalism in the Court's opinion might render future reform efforts more difficult than they would have been if the solicitor general's argument had carried the day. This commentary seeks to shed light on the Court's hesitation to recognize the uniqueness of health insurance and health care, noting that market-based exceptionalism in constitutional law has a long, dark history that the Court was understandably loath to repeat. Although the result of Chief Justice John Roberts' one-size-fits-all approach to constitutional analysis in this case is an odd holding that elides some genuine uniqueness of American health care, the alternative of health-care exceptionalism might have been much worse for our overall constitutional system.

  4. Bounds on the number of possible Higgs particles using grand unification and exceptional Lie groups

    International Nuclear Information System (INIS)

    El Naschie, M.S.

    2008-01-01

    The total sum of dimensions of a magnum exceptional Lie symmetry groups hierarchy is 4α-bar o =(4)(137+k o )≅548. Dividing this value among the various quantum fields leads to the possibility of an eight degrees of freedom Higgs field. However analyzing the same situation using sub groups of the largest exceptional Lie group leads to the conclusion that we are likely to find three Higgs particles only at the energy scale of the standard model. Consequently five of the eight degrees of freedom are unlikely to materialize as particles at this particular energy scale. This conclusion is reinforced by an entirely different approach based on grand unification analysis which excludes any grand unification using 4HD, i.e. four Higgs doublets. This leaves us with one, two and three Higgs doublets. Noting that a super symmetric standard model with two Higgs doublets gives almost perfect grand unification and that the result agrees with our exceptional Lie symmetry groups analysis, we exclude everything else. The final result is that we expect to find at least three more Higgs particles leading to a total of 66 elementary particles while at a somewhat higher energy, the expected number of 69 particles found using E-infinity theory is obtained

  5. Complex magnetic monopoles, geometric phases and quantum evolution in the vicinity of diabolic and exceptional points

    Nesterov, Alexander I; Aceves de la Cruz, F

    2008-01-01

    We consider the geometric phase and quantum tunneling in the vicinity of diabolic and exceptional points. We show that the geometric phase associated with the degeneracy points is defined by the flux of complex magnetic monopoles. In the limit of weak coupling, the leading contribution to the real part of the geometric phase is given by the flux of the Dirac monopole plus a quadrupole term, and the expansion of the imaginary part starts with a dipole-like field. For a two-level system governed by a generic non-Hermitian Hamiltonian, we derive a formula to compute the non-adiabatic, complex, geometric phase by integrating over the complex Bloch sphere. We apply our results to study a dissipative two-level system driven by a periodic electromagnetic field and show that, in the vicinity of the exceptional point, the complex geometric phase behaves like a step-function. Studying the tunneling process near and at the exceptional point, we find two different regimes: coherent and incoherent. The coherent regime is characterized by Rabi oscillations, with a one-sheeted hyperbolic monopole emerging in this region of the parameters. The two-sheeted hyperbolic monopole is associated with the incoherent regime. We show that the dissipation results in a series of pulses in the complex geometric phase which disappear when the dissipation dies out. Such a strong coupling effect of the environment is beyond the conventional adiabatic treatment of the Berry phase

    Current lithium ion battery technology is tied in with conventional reaction mechanisms such as insertion, conversion, and alloying reactions even though most future applications like EVs demand much higher energy densities than current ones. Exploring the exceptional reaction mechanism and related electrode materials can be critical for pushing current battery technology to a next level. Here, we introduce an exceptional reaction with a Co(OH)(2) material which exhibits an initial charge capacity of 1112 mAh g(-1), about twice its theoretical value based on known conventional conversion reaction, and retains its first cycle capacity after 30 cycles. The combined results of synchrotron X-ray diffraction and X-ray absorption spectroscopy indicate that nanosized Co metal particles and LiOH are generated by conversion reaction at high voltages, and CoxHy, Li2O, and LiH are subsequently formed by hydride reaction between Co metal, LiOH, and other lithium species at low voltages, resulting in a anomalously high capacity beyond the theoretical capacity of Co(OH)(2). This is further corroborated by AIMD simulations, localized STEM, and XPS. These findings will provide not only further understanding of exceptional lithium storage of recent nanostructured materials but also valuable guidance to develop advanced electrode materials with high energy density for next-generation batteries.

    Offspring of parents with exceptional longevity (OPEL) manifest lower prevalence of cardiovascular disease (CVD), but the role of lifestyle factors in this unique cohort is not known. Our study tested whether OPEL have lesser prevalence of CVD independent of lifestyle factors. Prevalence of CVD and CVD risk factors was assessed in a population of community-dwelling Ashkenazi Jewish adults aged 65 to 94 years. Participants included OPEL (n = 395), defined as having at least 1 parent living past the age of 95 years, and offspring of parents with usual survival (OPUS, n = 450), defined as having neither parent survive to 95 years. Medical and lifestyle information was obtained using standardized questionnaires. Socioeconomic status was defined based on validated classification scores. Dietary intake was evaluated with the Block Brief Food Frequency Questionnaire (2000) in a subgroup of the study population (n = 234). Our study found no significant differences in the prevalence of obesity, smoking, alcohol use, physical activity, social strata scores, and dietary intake between the 2 groups. After adjustment for age and gender, the OPEL demonstrated 29% lower odds of having hypertension (95% confidence interval [CI] 0.53 to 0.95), 65% lower odds of having had a stroke (95% CI 0.14 to 0.88), and 35% lower odds of having CVD (95% CI 0.43 to 0.98), compared with OPUS. In conclusion, exceptional parental longevity is associated with lower prevalence of CVD independent of lifestyle, socioeconomic status, and nutrition, thus highlighting the potential role of genetics in disease-free survival among individuals with exceptional parental longevity.

  9. Exceptional points near first- and second-order quantum phase transitions.

    Science.gov (United States)

    Stránský, Pavel; Dvořák, Martin; Cejnar, Pavel

    2018-01-01

    We study the impact of quantum phase transitions (QPTs) on the distribution of exceptional points (EPs) of the Hamiltonian in the complex-extended parameter domain. Analyzing first- and second-order QPTs in the Lipkin-Meshkov-Glick model we find an exponentially and polynomially close approach of EPs to the respective critical point with increasing size of the system. If the critical Hamiltonian is subject to random perturbations of various kinds, the averaged distribution of EPs close to the critical point still carries decisive information on the QPT type. We therefore claim that properties of the EP distribution represent a parametrization-independent signature of criticality in quantum systems.

    The correspondence between exotic quantum holonomy, which occurs in families of Hermitian cycles, and exceptional points (EPs) for non-Hermitian quantum theory is examined in quantum kicked tops. Under a suitable condition, an explicit expression of the adiabatic parameter dependencies of quasienergies and stationary states, which exhibit anholonomies, is obtained. It is also shown that the quantum kicked tops with the complexified adiabatic parameter have a higher-order EP, which is broken into lower-order EPs with the application of small perturbations. The stability of exotic holonomy against such bifurcation is demonstrated.

    2011-08-01

    A striking special ability in arranging picture stories was reported in an Asperger child (C.M.) showing an exceptional performance on Wechsler picture arrangement subtest. Neuropsychological examination did not disclose visuoperceptual and spatial defects, or working memory, attention and executive disorders, but revealed an attentional bias towards local details of complex structures. A specific assessment of C.M.'s understanding of picture stories demonstrated that, with respect to normal controls, he showed an enhanced ability to detect causal links among elements of a story. These findings provide support to the hypothesis that savantism can be related to strong systemizing in autism.

    Flexible pressure sensors with a high sensitivity over a broad linear range can simplify wearable sensing systems without additional signal processing for the linear output, enabling device miniaturization and low power consumption. Here, we demonstrate a flexible ferroelectric sensor with ultrahigh pressure sensitivity and linear response over an exceptionally broad pressure range based on the material and structural design of ferroelectric composites with a multilayer interlocked microdome geometry. Due to the stress concentration between interlocked microdome arrays and increased contact area in the multilayer design, the flexible ferroelectric sensors could perceive static/dynamic pressure with high sensitivity (47.7 kPa -1 , 1.3 Pa minimum detection). In addition, efficient stress distribution between stacked multilayers enables linear sensing over exceptionally broad pressure range (0.0013-353 kPa) with fast response time (20 ms) and high reliability over 5000 repetitive cycles even at an extremely high pressure of 272 kPa. Our sensor can be used to monitor diverse stimuli from a low to a high pressure range including weak gas flow, acoustic sound, wrist pulse pressure, respiration, and foot pressure with a single device.

  19. American Exceptionalism Revisited: Tax Relief, Poverty Reduction, and the Politics of Child Tax Credits

    Directory of Open Access Journals (Sweden)

    Joshua T.McCabe

    2016-07-01

    Full Text Available In the 1990s, several liberal welfare regimes (LWRs introduced child tax credits (CTCs aimed at reducing child poverty. While in other countries these tax credits were refundable, the United States alone introduced a nonrefundable CTC. As a result, the United States was the only country in which poor and working-class families were paradoxically excluded from these new benefits. A comparative analysis of Canada and the United States shows that American exceptionalism resulted from the cultural legacy of distinct public policies. We argue that policy changes in the 1940s institutionalized different “logics of appropriateness” that later constrained policymakers in the 1990s. Specifically, the introduction of family allowances in Canada and other LWR countries naturalized a logic of income supplementation in which families could legitimately receive cash benefits without the stigma of “welfare.” Lacking this policy legacy, American attempts to introduce a refundable CTC were quickly derailed by policymakers who saw it as equivalent to welfare. Instead, they introduced a narrow, nonrefundable CTC under the alternative logic of “tax relief,” even though this meant excluding the lowest-income families. The cultural legacy of past policies can explain American exceptionalism not only with regard to CTCs but to other social policies as well.

    Understanding aging is a grand challenge in biology. Exceptionally long-lived animals have mechanisms that underpin extreme longevity. Telomeres are protective nucleotide repeats on chromosome tips that shorten with cell division, potentially limiting life span. Bats are the longest-lived mammals for their size, but it is unknown whether their telomeres shorten. Using >60 years of cumulative mark-recapture field data, we show that telomeres shorten with age in Rhinolophus ferrumequinum and Miniopterus schreibersii , but not in the bat genus with greatest longevity, Myotis . As in humans, telomerase is not expressed in Myotis myotis blood or fibroblasts. Selection tests on telomere maintenance genes show that ATM and SETX , which repair and prevent DNA damage, potentially mediate telomere dynamics in Myotis bats. Twenty-one telomere maintenance genes are differentially expressed in Myotis , of which 14 are enriched for DNA repair, and 5 for alternative telomere-lengthening mechanisms. We demonstrate how telomeres, telomerase, and DNA repair genes have contributed to the evolution of exceptional longevity in Myotis bats, advancing our understanding of healthy aging.

  1. Generators of the exceptional group E8 as bilinear quark and lepton fields

    The quarks and leptons are assigned to the adjoint representation of the exceptional group E 8 using decompositions under the subgroups SU(9) and [SU(3)] 4 . Generators are constructed as linear combinations of bilinear quark and lepton fields. Closure of the algebra is used to determine the unknown coefficients of the linear combinations. It is noted that the Majorana spinors chi/sup μ//sub ν/ introduced to represent the adjoint representations of SU(9) and [SU(3)] 4 subgroups cannot be taken traceless. The trace chi/sup μ//sub ν/ should couple to the quark and lepton fields in order to close the algebra. The constraints on the bilinear fields which are of physical importance are introduced to obtain the right number of fermionic states in the adjoint representation. An attractive possibility of having an octet of strictly massless Majorana quarks and at least three massless Majorana leptons as a consequence of pure algebraic constraints is discussed. The exceptional subgroups E 7 and E 6 are identified and the explicit commutation relations are obtained. Using one assignment of E 6 the role of color-singlet lepton-lepton and quark-antiquark currents is pointed out

  2. Science, truth, and forensic cultures: the exceptional legal status of DNA evidence.

    2013-03-01

    Many epistemological terms, such as investigation, inquiry, argument, evidence, and fact were established in law well before being associated with science. However, while legal proof remained qualified by standards of 'moral certainty', scientific proof attained a reputation for objectivity. Although most forms of legal evidence (including expert evidence) continue to be treated as fallible 'opinions' rather than objective 'facts', forensic DNA evidence increasingly is being granted an exceptional factual status. It did not always enjoy such status. Two decades ago, the scientific status of forensic DNA evidence was challenged in the scientific literature and in courts of law, but by the late 1990s it was being granted exceptional legal status. This paper reviews the ascendancy of DNA profiling, and argues that its widely-heralded objective status is bound up with systems of administrative accountability. The 'administrative objectivity' of DNA evidence rests upon observable and reportable bureaucratic rules, records, recording devices, protocols, and architectural arrangements. By highlighting administrative sources of objectivity, this paper suggests that DNA evidence remains bound within the context of ordinary organisational and practical routines, and is not a transcendent source of 'truth' in the criminal justice system.

    Children with mild developmental disorders sometimes show giftedness. In this study, an original checklist was developed to identify gifted characteristics specific to science learning among twice-exceptional primary school children in Japan. The checklist consisted of 60 items on Attitudes, Thinking, Skills, and Knowledge/Understanding. A total of 86 children from eight primary schools in an urban area in Japan, 50% of whom had Learning Disabilities (LD), Attention Deficit/Hyperactivity Disorder (ADHD), and/or High-functioning Autism (HA), were observed using the checklist. Factor analysis revealed three factors. A cluster analysis with the subscale points of each factor identified three "gifted styles" in science. These were: (1) Spontaneous Style; (2) Expert Style; and (3) Solid Style. LD/ADHD/HA children characteristically displayed a Spontaneous Style while the non- LD/ADHD/HA children were characterized by the Solid Style. In both subject groups, the number of Expert Style children was the lowest with no significant difference in their numbers. Based on the results of this research, this paper discusses the implications of the findings for teaching science to twice-exceptional children and argues the benefits of inclusive science education for children with and without mild developmental disorders.

    We analyse generic AdS flux backgrounds preserving eight supercharges in D=4 and D=5 dimensions using exceptional generalised geometry. We show that they are described by a pair of globally defined, generalised structures, identical to those that appear for flat flux backgrounds but with different integrability conditions. We give a number of explicit examples of such “exceptional Sasaki-Einstein” backgrounds in type IIB supergravity and M-theory. In particular, we give the complete analysis of the generic AdS{sub 5} M-theory backgrounds. We also briefly discuss the structure of the moduli space of solutions. In all cases, one structure defines a “generalised Reeb vector” that generates a Killing symmetry of the background corresponding to the R-symmetry of the dual field theory, and in addition encodes the generic contact structures that appear in the D=4 M-theory and D=5 type IIB cases. Finally, we investigate the relation between generalised structures and quantities in the dual field theory, showing that the central charge and R-charge of BPS wrapped-brane states are both encoded by the generalised Reeb vector, as well as discussing how volume minimisation (the dual of a- and F-maximisation) is encoded.

    It gives a large insight of uranium deposits and general characters of uranium deposits on the planet (except France). It gives a review of the mineralized area of the main uranium producers country with a geographic and geologic recall. Moreover, it brings together all the important prospecting results from countries which have presented a report at the international conference on the pacific uses of atomic energy in geneva (8-20 august 1955). All these countries are cited except France. It described not only the payable deposits as each deposit brings interesting indications for future prospecting and might also become payable in the future. It started with the geological survey of USA and Canada and the geographic description of their different uranium deposit sites as both country present the largest uranium resources. In the same way, geographic and geological surveys of South Africa, Democratic Republic of Congo, Australia, India, Brazil, Argentina, Rhodesia, Mozambia, Sweden, Norway, United kingdom, Portugal, Yugoslavia, Italy, Austria and Switzerland are described.

    Full Text Available This paper addresses the 2008 Russian–Georgian conflict in the context of the post-Soviet spatial order, approached in terms of Carl Schmitt's theory of nomos and Giorgio Agamben's theory of the state of exception. The ‘five-day war’ was the first instance of the violation by Russia of the integrity of the post-Soviet spatial order established in the Belovezha treaties of December 1991. While from the beginning of the postcommunist period Russia functioned as the restraining force in the post-Soviet realm, the 2008 war has made further recourse to this function impossible, plunging the post-Soviet space into the condition of anomie, or the state of exception. This paper interprets this disruptive policy in the post-Soviet space as the continuation of the domestic political process of the ‘management of anomie,’ which has characterized the entire postcommunist period. In the conclusion, we address the implications of the transformation of the international order into the ethos of anomie for rethinking the ethical dimension of global politics.

    Organic semiconductors are in general known to have an inherently lower charge carrier mobility compared to their inorganic counterparts. Bimolecular recombination of holes and electrons is an important loss mechanism and can often be described by the Langevin recombination model. Here, the device physics of bulk heterojunction solar cells based on a nonfullerene acceptor (IDTBR) in combination with poly(3-hexylthiophene) (P3HT) are elucidated, showing an unprecedentedly low bimolecular recombination rate. The high fill factor observed (above 65%) is attributed to non-Langevin behavior with a Langevin prefactor (β/βL) of 1.9 × 10−4. The absence of parasitic recombination and high charge carrier lifetimes in P3HT:IDTBR solar cells inform an almost ideal bimolecular recombination behavior. This exceptional recombination behavior is explored to fabricate devices with layer thicknesses up to 450 nm without significant performance losses. The determination of the photoexcited carrier mobility by time-of-flight measurements reveals a long-lived and nonthermalized carrier transport as the origin for the exceptional transport physics. The crystalline microstructure arrangement of both components is suggested to be decisive for this slow recombination dynamics. Further, the thickness-independent power conversion efficiency is of utmost technological relevance for upscaling production and reiterates the importance of understanding material design in the context of low bimolecular recombination.

  8. Infinite families of (non)-Hermitian Hamiltonians associated with exceptional Xm Jacobi polynomials

    2013-01-01

    Using an appropriate change of variable, the Schrödinger equation is transformed into a second-order differential equation satisfied by recently discovered Jacobi-type X m exceptional orthogonal polynomials. This facilitates the derivation of infinite families of exactly solvable Hermitian as well as non-Hermitian trigonometric Scarf potentials and a finite number of Hermitian and an infinite number of non-Hermitian PT-symmetric hyperbolic Scarf potentials. The bound state solutions of all these potentials are associated with the aforesaid exceptional orthogonal polynomials. These infinite families of potentials are shown to be extensions of the conventional trigonometric and hyperbolic Scarf potentials by the addition of some rational terms characterized by the presence of classical Jacobi polynomials. All the members of a particular family of these ‘rationally extended polynomial-dependent’ potentials have the same energy spectrum and possess translational shape-invariant symmetry. The obtained non-Hermitian trigonometric Scarf potentials are shown to be quasi-Hermitian in nature ensuring the reality of the associated energy spectra. (paper)

    To describe the technical aspects of the Exceptional Circumstance Drug Dispensing Program of the Brazilian Ministry of Health, especially with respect to the cost of dispensed medication. Technical information was obtained from the ordinances that regulate the Program. Expenditure from 2000 to 2007 was obtained from the Sistema Único de Saúde's (Unified Healthcare System) Outpatient Information System. All drugs dispensed between 1993 and 2009 and the amount and cost of each procedure were evaluated, based on information from the high-complexity procedure authorization of each of the country's states. The Program changed with the increase in the number of pharmacological agents and presentations distributed by, and the number of diseases contemplated in the program. In 1993, the program distributed 15 pharmacological agents in 31 distinct presentations. This number increased to 109 agents in 243 presentations in 2009. Total Ministry of Health expenditure with medications was R$1,410,181,600.74 in 2007, almost twice the amount spent in 2000, R$684,975,404.43. Diseases whose expenditure increased in the period included chronic renal insufficiency, transplantation, and hepatitis C. The Exceptional Circumstance Drug Dispensing Program is in constant transformation, aimed at building instruments and strategies that can ensure and expand access to medication among the population. Alternatives should be sought to decrease the financial impact of the Program to a level that does not impact other sectors of the health care system, given the high cost associated with novel interventions.

  11. Knot wormholes and the dimensional invariant of exceptional Lie groups and Stein space hierarchies

    Elokaby, Ayman

    2009-01-01

    The present short note points out a most interesting and quite unexpected connection between the number of distinct knot as a function of their crossing number and exceptional Lie groups and Stein space hierarchies. It is found that the crossing number 7 plays the role of threshold similar to 4 and 5 in E-infinity theory and for the 11 crossing the number of distinct knots is very close to 4α-bar 0 +1=548+1=549, where α-bar 0 =137 is the inverse integer electromagnetic fine structure constant. This is particularly intriguing in view of a similar relation pertinent to the 17 two and three Stein spaces where the total dimension is Σ 1 17 Stein=5α-bar 0 +1=685+1=686, as well as the sum of the eight exceptional Lie symmetry groups Σ i=1 8 |E i |=4α-bar 0 =548. The slight discrepancy of one is explained in both cases by the inclusion of El Naschie's transfinite corrections leading to Σ i=1 8 |E i |=(4)(137+k 0 )=548.328157 and Σ i=1 17 Stein=(5)(137+k 0 )=685.41097, where k o = φ 5 (1 - φ 5 ) and φ=(√(5)-1)/2.

  12. Migration and Freedom of Movement of Workers: EU Law, Crisis and the Cypriot States of Exception

    2013-11-01

    Full Text Available This paper examines the authoritarian immigration policy of the Republic of Cyprus (RoC, which often results in the denial of the rights of migrants, TCNs, and EUNs. It examines how the mode of immigration control is connected to the particular state of exception in Cyprus known as ‘the doctrine of necessity’. It focuses particularly the issue of criminalizing, detention and expulsion of migrants, both TCNs and EUNs and the denial of residency rights for TCNs. The paper introduces the basic components towards an analytical frame for understanding and critiquing the current legal framework. Repressive migration control is a manifestation of an ill-construed conception of ‘sovereignty’ in a divided country, which the State seeks to justify on the grounds of ‘necessity’ and ‘exception’. In addition, the RoC is currently facing the banking/economic crisis and mass unemployment, which has provided a fertile ground for racism and xenophobia. The paper concludes with some ideas about the alternative policies ahead. Important for this paper are the current global and European debates around the ‘states of exception’, ‘emergency’, ‘necessity’, and ‘sovereignty’ in the context of the dissensus or fundamental disagreement over the issue migration and the racialization of subaltern migrants. The case of Cyprus is discussed, in part as an exception, but also as a particular instance of a broader global and European issue.

    The origin of individual differences in aptitude, defined as a domain-specific skill within the normal ability range, and talent, defined as a domain specific skill of exceptional quality, is under debate. The nature of the variation in aptitudes and exceptional talents across different domains was investigated in a population based twin sample. Self-report data from 1,685 twin pairs (12-24 years) were analyzed for Music, Arts, Writing, Language, Chess, Mathematics, Sports, Memory, and Knowledge. The influence of shared environment was small for both aptitude and talent. Additive and non-additive genetic effects explained the major part of the substantial familial clustering in the aptitude measures with heritability estimates ranging between .32 and .71. Heritability estimates for talents were higher and ranged between .50 and .92. In general, the genetic architecture for aptitude and talent was similar in men and women. Genetic factors contribute to a large extent to variation in aptitude and talent across different domains of intellectual, creative, and sports abilities.

    Emeraldine salt form of polyaniline (PANI) was synthesized by chemical oxidative polymerisation method using ammonium persulfate as oxidant. Resultant emeraldine salt form of PANI was dedoped using ammonia solution and then re-doped with camphor sulphonic acid (CSA), naphthaline sulphonic acid (NSA), hydrochloric acid (HCl), and m-cresol. Thin films of these doped PANI samples were deposited on glass substrates using solution casting method with m-cresol as solvent. A level surface was employed to get homogeneous thin films of uniform thickness. Detailed X-ray diffraction studies have shown that the films are exceptionally crystalline. The crystalline peaks observed in the XRD spectra can be indexed to simple monoclinic structure. FTIR and Raman spectroscopy studies provide convincing explanation for the exceptional crystallinity observed in these polymer films. FESEM and AFM images give better details of surface morphology of doped PANI films. The DC electrical conductivity of the samples was measured using four point probe technique. It is seen that the samples also exhibit quite high DC electrical conductivity, about 287 S/cm for CSA doped PANI, 67 S/cm for NSA doped PANI 65 S/cm for HCl doped PANI, and just below 1 S/cm for m-cresol doped PANI. Effect of using the level surface for solution casting is studied and correlated with the observed crystallinity.

    Full Text Available Cultural monuments mark historical past. They are included in anthropogenic tourist values. They present rare copies of creativity and they have exceptional artistic and esthetic values. The most numerous group are sacral objects. The largest attention deserve objects assigned in World cultural inheritance - monastery Studenica and monastery Sopoćani with old town Ras. It is necessary to build caterer capacities, parking lots and sanitary devices in encirclement. Manifestations and presentations on domestic and foreign market contribute to cultural affirmation. Tourist valorization is impeded with that there are no evidence about number of visitors. In separating priorities we must consider uniqueness, rarity and fame. That’s the reason why Čele kula has tourist importance. Cultural monuments increase stay and serve as complementary tourist values.

    2016-11-01

    Full Text Available The event referred as The Refugee Crisis after 2015, the year that the European countries confronted with a huge migration wave, is rather a crisis of modernity. In this paper, the discourse created by the images most frequently used in media all over the world when depicting this crisis is examined; issues such as belonging, border, nation-state, home and homelessness, self and the other, freedom and confinement, history and ethics are discussed; and whether these images create the grounds for the viewers to attain a critical position towards this crisis as a crisis of modernity is discussed. It is concluded that these images help solve this crisis on behalf of modernity by representing this event as an exception of modernity rather than a consequence of it, reproducing the colonialist discourse.

Data reported by independent contractors performing certain work at mining locations are depicted separately in this report. For ease of comparison with other metal and nonmetallic mineral mining industries and with coal mining, summary reference tabulations are included at the end of both the operator and the contractor sections of this report.

  8. Catalytic oxidative conversion of cellulosic biomass to formic acid and acetic acid with exceptionally high yields

    KAUST Repository

    Zhang, Jizhe

    2014-09-01

    Direct conversion of raw biomass materials to fine chemicals is of great significance from both economic and ecological perspectives. In this paper, we report that a Keggin-type vanadium-substituted phosphomolybdic acid catalyst, namely H4PVMo11O40, is capable of converting various biomass-derived substrates to formic acid and acetic acid with high selectivity in a water medium and oxygen atmosphere. Under optimized reaction conditions, H4PVMo11O40 gave an exceptionally high yield of formic acid (67.8%) from cellulose, far exceeding the values achieved in previous catalytic systems. Our study demonstrates that heteropoly acids are generally effective catalysts for biomass conversion due to their strong acidities, whereas the composition of metal addenda atoms in the catalysts has crucial influence on the reaction pathway and the product selectivity. © 2013 Elsevier B.V.

  9. Exceptional versus superPoincaré algebra as the defining symmetry of maximal supergravity

    International Nuclear Information System (INIS)

    Ananth, Sudarshan; Brink, Lars; Majumdar, Sucheta

    2016-01-01

    We describe how one may use either the superPoincaré algebra or the exceptional algebra to construct maximal supergravity theories in the light-cone formalism. The d=4 construction shows both symmetries albeit in a non-linearly realized manner. In d=11, we find that we have to choose which of these two symmetries to use, in constructing the theory. In order to understand the other “unused" symmetry, one has to perform a highly non-trivial field redefinition. We argue that this shows that one cannot trust counterterm arguments that do not take the full symmetry of the theory into account. Finally we discuss possible consequences for Superstring theory and M-theory.

    We are constructing a hierarchy of kissing numbers representing singular contact points of hyper-spheres in exceptional Lie symmetry groups lattice arrangement embedded in the 26 dimensional bosonic strings spacetime. That way we find a total number of points and dimensions equal to 548. This is 52 more than the order of E 8 E 8 of heterotic string theory and leads to the prediction of 69 elementary particles at an energy scale under 1 T. In other words, our mathematical model predicts nine more particles than what is currently experimentally known to exist in the standard model of high energy physics namely only 60. The result is thus in full agreement with all our previous theoretical findings

    2011-06-01

    Full Text Available Abstract Exceptional pupils enrolled in Canadian French immersion programs rarely have access to the same range of special education programs and services that are available to students in the regular English program. More often than not, students with special needs are encouraged to transfer to English programs to access necessary support services. This counselling-out process perpetuates the elitist status commonly attributed to French immersion programs. From a critical pedagogy perspective, this inquiry examines the lack of incentive on the part of multiple French immersion stakeholders to accommodate students with special needs. It further attempts to unveil the myths created by these stakeholders to better understand this discriminatory educational practice. The impact of federal and provincial funding models on access to special education programs and services is discussed, and the application of funding allocations by English-language district school boards is explored. The inquiry concludes with recommendations to promote more inclusionary practices.

  13. A radical proposition: the brief but exceptional history of the Seattle school clinic, 1914-21.

    2013-04-01

    This article examines the history of the Seattle school clinic (1914-21) and the efforts of public school administrators to institutionalize a full-service medical program for poor and working class children. At its height, thirty-six volunteer physicians and thirteen partially paid dentists organized within nine departments performed a range of diagnostic and "corrective" surgical procedures, including tonsillectomies, circumcisions, and eye surgeries. These practices were not funded by other public school systems across the United States, almost all of which delineated between prevention and treatment services. This article explains the exceptional nature of the clinic, examines the institutional tensions instigated by the expression of medical authority within the schools, and considers how clinic technologies influenced state-school-child relations.

    Vision has revolutionized the way animals explore their environment and interact with each other and rapidly became a major driving force in animal evolution. However, direct evidence of how ancient animals could perceive their environment is extremely difficult to obtain because internal eye structures are almost never fossilized. Here, we reconstruct with unprecedented resolution the three-dimensional structure of the huge compound eye of a 160-million-year-old thylacocephalan arthropod from the La Voulte exceptional fossil biota in SE France. This arthropod had about 18,000 lenses on each eye, which is a record among extinct and extant arthropods and is surpassed only by modern dragonflies. Combined information about its eyes, internal organs and gut contents obtained by X-ray microtomography lead to the conclusion that this thylacocephalan arthropod was a visual hunter probably adapted to illuminated environments, thus contradicting the hypothesis that La Voulte was a deep-water environment.

    The Amazon river basin has been recently affected by extreme climatic events, such as the exceptional drought of 2005, with significant impacts on human activities and ecosystems. In spite of the importance of monitoring freshwater stored and moving in such large river basins, only scarce measurements of river stages and discharges are available and the signatures of extreme drought conditions on surface freshwater dynamics at the basin scale are still poorly known. Here we use continuous multisatellite observations of inundation extent and water levels between 2003 and 2007 to monitor monthly variations of surface water storage at the basin scale. During the 2005 drought, the amount of water stored in the river and floodplains of the Amazon basin was ∼130 km 3 (∼70%) below its 2003–7 average. This represents almost a half of the anomaly of minimum terrestrial water stored in the basin as estimated using the Gravity Recovery and Climate Experiment (GRACE) data. (letter)

    In the mountain environment, the steep channels play a key-role in the drainage networks. Notably, the sediment transport processes that here occur, can affect aspects as the geomorphic changes, channel evolution, reservoir management, infrastructure design and hazard assessment. Due to the complex and changeable hydraulic and morphological features that characterize the mountain environment, the steep channels can exhibit fluvial and/or debris-flow transport with magnitude of sediment delivery that, in the same basin, may strongly vary from event to event. In the light of these challenging conditions, appears clear as an accurate monitoring and investigation of sediment dynamics is of critical importance in the steep mountain channels. Such monitoring has even more significance if it is maintained over long-period, enabling to investigate even the role of high magnitude/low frequency events. Using a dataset 29 years-wide, this work aims to investigate the temporal trend of sediment dynamic in the Rio Cordon (Eastern Italian Alps). The Rio Cordon is a steep mountain channel (mean slope = 13%) characterized by step-pool and riffle-pool morphology. The basin (5 km2)exhibits a prevalent nivo-pluvial runoff regime. Since 1986, the catchment is equipped with a monitoring station, that continuously records water discharge, bedload and suspended load (at 1 hr intervals, and 5 min intervals during floods). In September 1994 an exceptional event (RI > 100 years) occurred in the study site, mobilizing about 4000 tons of material. Currently, the structure is managed by ARPA Veneto - Regional Department for Land Safety. In terms of magnitude, the 31 floods recorded by the monitoring station show a wide range of hydraulic forcing (i.e. peak discharge and effective runoff) and amount transported. Specifically, Qpeak ranges within one order of magnitude (1.02 - 10.42 m3 s-1), while the amount of bedload and suspended load varies by more than 3 orders (i.e. 0.9 t transported by

    Full Text Available The notion of the United States as an “exceptional” country not only has extensive historical and sociological development, but also a vast political backing that has penetrated different government administrations. This has invariably transcended decisions that affect the position of this country in relation to international law. However, there are those who argue that since the inauguration of Donald J. Trump as the new president of the United States, this doctrine has come to an end. For this reason, the author proposes to explore, initially, the concept and the different movements that have arisen around “American exceptionalism”, with a historical, political and international relations approach. Then examines the relationship between the current American president and this notion, analyzes the link between the new administration and the international law, and finally, tries to answer the question: Is it the end of 'American exceptionalism'?

  18. "Genetic exceptionalism" in medicine: clarifying the differences between genetic and nongenetic tests.

    2003-04-01

    Predictive genetic tests are now available for assessing susceptibility to a variety of conditions, including breast and colon cancer, hemochromatosis, and Alzheimer and Huntington disease. Much controversy surrounds the application of these tests, stemming from their similarities to and differences from other tests commonly used in asymptomatic persons. Some have argued that genetic tests are unique and therefore justify special consideration with regard to informed consent and privacy. This paper examines the arguments for such "genetic exceptionalism" and concludes that no clear, significant distinctions between genetic and nongenetic tests justify a different approach to testing by clinicians. Nevertheless, with many genetic tests, the results may cause stigmatization, family discord, and psychological distress. Regardless of whether a test is genetic, when this combination of characteristics is present and when health care providers are not specifically trained to interpret results, testing should be performed with particular caution and the highest standards of informed consent and privacy protection should be applied.

    Full Text Available Though it is accepted that emerging infectious diseases are a threat to planet biodiversity, little information exists about their role as drivers of species extinction. Populations are also affected by natural catastrophes and other pathogens, making it difficult to estimate the particular impact of emerging diseases. Border disease virus genogroup 4 (BDV-4 caused a previously unreported decrease in populations of Pyrenean chamois (Rupicapra p. pyrenaica in Spain. Using a population viability analysis, we compared probabilities of extinction of a virtual chamois population affected by winter conditions, density dependence, keratoconjunctivitis, sarcoptic mange and BDV outbreaks. BDV-affected populations showed double risk of becoming extinct in 50 years, confirming the exceptional ability of this virus to drive chamois populations.

    2003-01-01

    The uniformity, for the family of exceptional Lie algebras g, of the decompositions of the powers of their adjoint representations is now well known for powers up to four. The paper describes an extension of this uniformity for the totally antisymmetrized nth powers up to n = 9, identifying families of representations with integer eigenvalues 5, ..., 9 for the quadratic Casimir operator, in each case providing a formula for the dimensions of the representations in the family as a function of D = dim g. This generalizes previous results for powers j and Casimir eigenvalues j, j ≤ 4. Many intriguing, perhaps puzzling, features of the dimension formulae are discussed and the possibility that they may be valid for a wider class of not necessarily simple Lie algebras is considered

    We introduce an extended Kepler-Coulomb quantum model in spherical coordinates. The Schrödinger equation of this Hamiltonian is solved in these coordinates and it is shown that the wave functions of the system can be expressed in terms of Laguerre, Legendre and exceptional Jacobi polynomials (of hypergeometric type). We construct ladder and shift operators based on the corresponding wave functions and obtain their recurrence formulas. These recurrence relations are used to construct higher-order, algebraically independent integrals of motion to prove superintegrability of the Hamiltonian. The integrals form a higher rank polynomial algebra. By constructing the structure functions of the associated deformed oscillator algebras we derive the degeneracy of energy spectrum of the superintegrable system.

    Although many genetic and nongenetic factors interact to determine an individual's physical phenotype, there has been limited examination of the contribution of family history of exceptional parental longevity on decline in physical function in aging. The LonGenity study recruited a relatively genetically homogenous cohort of Ashkenazi Jewish adults age 65 and older, who were defined as either offspring of parents with exceptional longevity ([OPEL]: having at least one parent who lived to age 95 or older) or offspring of parents with usual survival ([OPUS]: neither parent survived to age 95). Decline in performance on objective measures of strength (grip strength), balance (unipedal stance), and mobility (gait speed) as well as a composite physical function measure, the Short physical performance battery (SPPB), were compared between the two groups over a median follow-up of 3.2 years, accounting for age, sex, education, and comorbidities. Of the 984 LonGenity participants (mean age 76, 55% women), 448 were OPEL and 536 were OPUS. Compared to OPUS, OPEL had slower decline on measures of unipedal stance (-0.03 log-units/year, p = .026), repeated chair rise (0.13 s/year, p = .020) and SPPB (-0.11 points/year, p = .002). OPEL women had slower decline on chair rise and SPPB scores compared to OPUS women, although OPEL men had slower decline on unipedal stance compared to OPUS men. Our findings provide evidence that variation in late-life decline in physical function is associated with familial longevity, and may vary for men and women. © The Author 2017.

  3. Non-adaptive territory selection by a bird with exceptionally long parental care

    Full Text Available High-quality territories are expected to provide greater fitness return for breeding individuals and, thus, are likely to have higher long-term occupation rate in comparison to low-quality territories. However, if environmental and ecological cues used for territory selection cannot reliably predict true territory quality, a mismatch between preferences and fitness may occur. We suggest that this kind of non-adaptive territory selection is more likely in species with long reproductive cycles, as a long time interval between territory establishment and young fledgling should reduce predictability of conditions during the critical stages of brood care. In this study, we investigated adaptiveness of territory selection in a migratory bird with exceptionally long parental care, the mute swan Cygnus olor, which requires over four months to complete the entire reproductive cycle from egg laying to young fledging. For this purpose, we collected information on the long-term (10–19 years occupancy of 222 swan breeding territories and correlated it with reproductive performance (n = 1,345 breeding attempts and body condition of breeding adults. We found that long-term occupancy positively correlated with the timing of breeding, suggesting that individuals settled earlier in the attractive, frequently occupied territories. By contrast, we found no relationship between territory occupancy and reproductive output (hatching and fledging success or adult body condition. The results indicate that at the time of territory selection swans might not be able to reliably assess territory quality, likely due to: (1 exceptionally long period of parental care, which reduces temporal correlation between the conditions at the time of territory selection and conditions during chick rearing; and (2 unpredictability of human-related activities that had a major impact on reproductive output of swan pairs in our population.

  4. BILP-19-An Ultramicroporous Organic Network with Exceptional Carbon Dioxide Uptake.

    Porous benzimidazole-based polymers (BILPs) have proven to be promising for carbon dioxide capture and storage. The polarity of their chemical structure in combination with an inherent porosity allows for adsorbing large amounts of carbon dioxide in combination with high selectivities over unpolar guest molecules such as methane and nitrogen. For this reason, among purely organic polymers, BILPs contain some of the most effective networks to date. Nevertheless, they are still outperformed by competitive materials such as metal-organic frameworks (MOFs) or metal doped porous polymers. Here, we report the synthesis of BILP-19 and its exceptional carbon dioxide uptake of up to 6 mmol•g-1 at 273 K, making the network comparable to state-of-the-art materials. BILP-19 precipitates in a particulate structure with a strongly anisotropic growth into platelets, indicating a sheet-like structure for the network. It exhibits only a small microporous but a remarkable ultra-microporous surface area of 144 m2•g-1 and 1325 m2•g-1, respectively. We attribute the exceptional uptake of small guest molecules such as carbon dioxide and water to the distinct ultra-microporosity. Additionally, a pronounced hysteresis for both guests is observed, which in combination with the platelet character is probably caused by an expansion of the interparticle space, creating additional accessible ultra-microporous pore volume. For nitrogen and methane, this effect does not occur which explains their low affinity. In consequence, Henry selectivities of 123 for CO2/N2 at 298 K and 12 for CO2/CH4 at 273 K were determined. The network was carefully characterized with solid-state nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy, thermal gravimetry (TG) and elemental analyses as well as physisorption experiments with Ar, N2, CO2, CH4 and water.

    Despite the status of the eye as an ``organ of extreme perfection'', theory suggests that complex eyes can evolve very rapidly. The fossil record has, until now, been inadequate in providing insight into the early evolution of eyes during the initial radiation of many animal groups known as the Cambrian explosion. This is surprising because Cambrian Burgess-Shale-type deposits are replete with exquisitely preserved animals, especially arthropods, that possess eyes. However, with the exception of biomineralized trilobite eyes, virtually nothing is known about the details of their optical design. Here we report exceptionally preserved fossil eyes from the Early Cambrian (~515 million years ago) Emu Bay Shale of South Australia, revealing that some of the earliest arthropods possessed highly advanced compound eyes, each with over 3,000 large ommatidial lenses and a specialized `bright zone'. These are the oldest non-biomineralized eyes known in such detail, with preservation quality exceeding that found in the Burgess Shale and Chengjiang deposits. Non-biomineralized eyes of similar complexity are otherwise unknown until about 85 million years later. The arrangement and size of the lenses indicate that these eyes belonged to an active predator that was capable of seeing in low light. The eyes are more complex than those known from contemporaneous trilobites and are as advanced as those of many living forms. They provide further evidence that the Cambrian explosion involved rapid innovation in fine-scale anatomy as well as gross morphology, and are consistent with the concept that the development of advanced vision helped to drive this great evolutionary event.

    There are more than 50 million Americans with disabilities, approximately half of whom are students in a mainstreamed classroom. The National Association for Gifted Children estimates that approximately 3 million of those, 6% of the student population, are academically gifted, and 150,000 - 300,000 students of those are twice or triple exceptional (2e and 3e, respectively). The 2e and 3e refers to intellectually gifted children who also have some form(s) of disability. Unfortunately most schools in the US identify children by their giftedness or by their disability, but rarely by both. An apparent trend with 2e children, particularly when autism is paired with gifted, is that students identify with their disability instead of their strengths. 2e students have shown a propensity for interests in the science and technology fields. Few specialized programs and/or resources in STEM exist to engage and involve these exceptional students and fewer still is the number of faculty and staff trained to work with the twice and triple exceptionalities. Palmetto Scholars Academy (PSA), Charleston, SC a school for gifted and talented, provides a differentiated program to meet the educational needs of gifted learners, while also addressing the students' social/emotional needs. The Brown/MIT NASA Lunar Science Institute, in conjunction with the NASA South Carolina Space Grant Consortium, is working directly with educators from the PSA to identify what kinds of materials they need and what mediums work best for the different student (cap)abilities. This partnership will provide a means of 'consciousness raising' for teachers to help students develop their strengths and educators will gain a new understanding of 2e and 3e that will transfer into better instruction. One technique being implemented is the use of STEM-oriented engineering and technology design challenges and problem solving. These tasks allow students to use a variety of integrative and multi-disciplinary skills for

  7. Two Exceptions in the Large SEP Events of Solar Cycles 23 and 24

    We discuss our findings from a survey of all large solar energetic particle (SEP) events of Solar Cycles 23 and 24, i.e. the SEP events where the intensity of greater than 10 megaelectronvolts protons observed by GOES (Geostationary Operational Environmental Satellite) was greater than 10 proton flux units. In our previous work (Gopalswamy et al. in Geophys.Res.Lett. 41, 2673, 2014) we suggested that ground level enhancements (GLEs) in Cycles 23 and 24 also produce an intensity increase in the GOES greater than 700 megaelectronvolts proton channel. Our survey, now extended to include all large SEP events of Cycle 23, confirms this to be true for all but two events: i) the GLE of 6 May 1998 (GLE57) for which GOES did not observe enhancement in greater than 700 megaelectronvolts protons intensities and ii) a high-energy SEP event of 8 November 2000, for which GOES observed greater than 700 megaelectronvolts protons but no GLE was recorded. Here we discuss these two exceptions. We compare GLE57 with other small GLEs, and the 8 November 2000 SEP event with those that showed similar intensity increases in the GOES greater than 700 megaelectronvolts protons but produced GLEs. We find that, because GOES greater than 700 megaelectronvolts proton intensity enhancements are typically small for small GLEs, they are difficult to discern near solar minima due to higher background. Our results also support that GLEs are generally observed when shocks of the associated coronal mass ejections (CMEs) form at heights 1.2-1.93 solar radii [R (sub solar)] and when the solar particle release occurs between 2-6 solar radii [R (sub solar)]. Our secondary findings support the view that the nose region of the CME-shock may be accelerating the first-arriving GLE particles and the observation of a GLE is also dependent on the latitudinal connectivity of the observer to the CME-shock nose. We conclude that the GOES greater than 700 megaelectronvolts proton channel can be used as an indicator

    Tendinous and subcutaneous xanthomas are most commonly associated with primary hyperlipidemia. Xanthomatosis caused by cholesterol deposition can be a high risk marker for cardiovascular disease related to premature atherosclerosis; thus, early recognition of this diagnosis may reduce mortality and morbidity. Achilles tendon involvement is most common, followed by the extensor tendons of the hand and elbow. We present an exceptional case of tendinous and tuberous xanthomas, with intraoperative and histologic correlation, in a 34-year-old female manifesting with xanthomatous deposits of nearly all ankle tendons, plantar aponeurosis, extensor tendons of the hands, and various locations within the integumentum. To the authors' knowledge, only four studies to date have focused specifically on imaging findings of multifocal xanthomas. Thus, the radiographic and MR imaging descriptions of xanthomas in this report further add to the existing literature by helping to identify imaging characteristics of this multifocal systemic disease. The diagnosis of this condition should alert the physician to the presence of a dyslipidemia that can be treated with dietary modifications and/or drug therapy. (orig.)

    As attention to, and motivation for, emergency medical services (EMS)-related research continues to grow, particularly exception from informed consent (EFIC) research, it is important to understand the thoughts, beliefs, and experiences of EMS providers who are actively engaged in the research. We explored the attitudes, beliefs, and experiences of EMS providers regarding their involvement in prehospital emergency research, particularly EFIC research. Using a qualitative design, 24 participants were interviewed including nationally registered paramedics and Virginia-certified emergency medical technicians employed at Richmond Ambulance Authority, the participating EMS agency. At the time of our interviews, the EMS agency was involved in an EFIC trial. Transcribed interview data were coded and analyzed for themes. Findings were presented back to the EMS agency for validation. Overall, there appeared to be support for prehospital emergency research. Participants viewed research as necessary for the advancement of the field of EMS. Improvement in patient care was identified as one of the most important benefits. A number of ethical considerations were identified: individual risk versus public good and consent. The EMS providers in our study were open to working with EMS researchers throughout the community consultation and public disclosure process. The EMS providers in our study valued research and were willing to participate in studies. Support for research was balanced with concerns and challenges regarding the role of providers in the research process.

    Full Text Available The purpose of the article is to analyse the migration corridor managed by the state authorities on the Balkan migration route in the second half of 2015, understand it from the perspective of the existing legal and institutional frameworks, and show that the corridor was a phenomenon outside of national and European positive law, while at the same time it responded to the requirements of international human rights principles. The corridor was a clear, intentional and coordinated deviation from legal provisions. It amounted to a state of exception, a certain level of state of emergency in which the rules adopted by the national and European legislatures were suspended and replaced by internal instructions or decrees, or even with constantly changing state practices. The analysis involved comparison of a positive normative framework with the actual procedures carried out by the state structures, and identification of discrepancies which were then qualitatively evaluated from the perspective of international standards. Another purpose of the article was to show that the corridor which was also sometimes referred to as a “humanitarian corridor”, only seemed humanitarian since in fact it served a completely different purpose, namely the interests of state authorities for the refugees and migrants to leave their territories as quickly as possible.

    The carnivoran giant panda has a specialized bamboo diet, to which its alimentary tract is poorly adapted. Measurements of daily energy expenditure across five captive and three wild pandas averaged 5.2 megajoules (MJ)/day, only 37.7% of the predicted value (13.8 MJ/day). For the wild pandas, the mean was 6.2 MJ/day, or 45% of the mammalian expectation. Pandas achieve this exceptionally low expenditure in part by reduced sizes of several vital organs and low physical activity. In addition, circulating levels of thyroid hormones thyroxine (T4) and triiodothyronine (T3) averaged 46.9 and 64%, respectively, of the levels expected for a eutherian mammal of comparable size. A giant panda-unique mutation in the DUOX2 gene, critical for thyroid hormone synthesis, might explain these low thyroid hormone levels. A combination of morphological, behavioral, physiological, and genetic adaptations, leading to low energy expenditure, likely enables giant pandas to survive on a bamboo diet.

    A minimum of two positive, adequate, and well-controlled clinical trials has historically been the gold standard for providing substantial evidence to support regulatory approval of a new medicine. Nevertheless, the present analysis of European Marketing Authorizations granted between 2012 and 2016 showed that 45% of new active substances were approved based on a single pivotal clinical trial. For therapeutic areas such as oncology and cardiovascular diseases, approvals based on a single pivotal trial are the rule rather than the exception, whereas new medicines within the nervous system area were generally supported by two or more pivotal trials. While overall similar trends have been observed in the US, the recent US Food and Drug Administration approvals of nervous system medicines based on a single pivotal trial suggest that a case-by-case scientific evaluation of the totality of evidence is increasingly applied to facilitate faster access of new medicines to patients suffering from serious diseases. © 2017 American Society for Clinical Pharmacology and Therapeutics.

    We present a lattice study of the equation of state in Yang-Mills theory based on the exceptional G{sub 2} gauge group. As is well-known, at zero temperature this theory shares many qualitative features with real-world QCD, including the absence of colored states in the spectrum and dynamical string breaking at large distances. In agreement with previous works, we show that at finite temperature this theory features a first-order deconfining phase transition, whose nature can be studied by a semi-classical computation. We also show that the equilibrium thermodynamic observables in the deconfined phase bear striking quantitative similarities with those found in SU(N) gauge theories: in particular, these quantities exhibit nearly perfect proportionality to the number of gluon degrees of freedom, and the trace anomaly reveals a characteristic quadratic dependence on the temperature, also observed in SU(N) Yang-Mills theories (both in four and in three spacetime dimensions). We compare our lattice data with analytical predictions from effective models, and discuss their implications for the deconfinement mechanism and high-temperature properties of strongly interacting, non-supersymmetric gauge theories. Our results give strong evidence for the conjecture that the thermal deconfining transition is governed by a universal mechanism, common to all simple gauge groups.

    We compiled all credible repeated lion surveys and present time series data for 47 lion (Panthera leo) populations. We used a Bayesian state space model to estimate growth rate-λ for each population and summed these into three regional sets to provide conservation-relevant estimates of trends since 1990. We found a striking geographical pattern: African lion populations are declining everywhere, except in four southern countries (Botswana, Namibia, South Africa, and Zimbabwe). Population models indicate a 67% chance that lions in West and Central Africa decline by one-half, while estimating a 37% chance that lions in East Africa also decline by one-half over two decades. We recommend separate regional assessments of the lion in the World Conservation Union (IUCN) Red List of Threatened Species: already recognized as critically endangered in West Africa, our analysis supports listing as regionally endangered in Central and East Africa and least concern in southern Africa. Almost all lion populations that historically exceeded ∼ 500 individuals are declining, but lion conservation is successful in southern Africa, in part because of the proliferation of reintroduced lions in small, fenced, intensively managed, and funded reserves. If management budgets for wild lands cannot keep pace with mounting levels of threat, the species may rely increasingly on these southern African areas and may no longer be a flagship species of the once vast natural ecosystems across the rest of the continent.

    Cavitation erosion and corrosion of structural materials are serious concerns for marine and offshore industries. Durability and performance of marine components are severely impaired due to degradation from erosion and corrosion. Utilization of advanced structural materials can play a vital role in limiting such degradation. High entropy alloys (HEAs) are a relatively new class of advanced structural materials with exceptional properties. In the present work, we report on the cavitation erosion behavior of Al 0.1 CoCrFeNi HEA in two different media: distilled water with and without 3.5wt% NaCl. For comparison, conventionally used stainless steel SS316L was also evaluated in identical test conditions. Despite lower hardness and yield strength, the HEA showed significantly longer incubation period and lower erosion-corrosion rate (nearly 1/4th) compared to SS316L steel. Enhanced erosion resistance of HEA was attributed to its high work-hardening behavior and stable passivation film on the surface. The Al 0.1 CoCrFeNi HEA showed lower corrosion current density, high pitting resistance and protection potential compared to SS316L steel. Further, HEA showed no evidence of intergranular corrosion likely due to the absence of secondary precipitates. Although, the degradation mechanisms (formation of pits and fatigue cracks) were similar for both the materials, the damage severity was found to be much higher for SS316L steel compared to HEA.

    Dual-porous Ge nanostructures are synthesized via two straightforward steps. Compared with conventional approaches related to porous Ge materials, different types of pores can be readily generated by adjusting the relative ratio of the precursor amounts for GeO2 and SiO2. Unlike using hard templates with different sizes for introducing secondary pores, this system makes a uniformly blended structure of porogen and active sites in the nanoscale range. When GeO2 is subjected to zincothermic reduction, it is selectively converted to pure Ge still connected to unreacted SiO2. During the reduction process, primary pores (larger than 50 nm) are formed by eliminating zinc oxide by-products, while inactive SiO2 with respect to zinc metal could contribute to retaining the overall structure. Finally, the HF treatment completely leaches remaining SiO2 and formed secondary pores (micro/mesopores) to complete the dual-porous Ge structure. The resulting Ge structure is tested as an anode material for lithium-ion batteries. The Ge electrode exhibits an outstanding reversibility and an exceptional cycling stability corresponding to a capacity retention of 100% after 100 cycles at C/5 and of 94.4% after 300 cycles at C/2. Furthermore, multi-scale pores facilitate a facile Li-ion accessibility, resulting in an excellent rate capability delivering ∼740 mAh g-1 at 5C.

    We study realisations of the exceptional non-linear (quadratically generated, or W-type) N=8 and N=7 superconformal algebras with Spin(7) and G 2 affine symmetry currents, respectively. Both the N=8 and N=7 algebras admit unitary highest-weight representations in terms of a single boson and free fermions in 8 of Spin(7) and 7 of G 2 , with the central charges c 8 =26/5 and c 7 =5, respectively. Furthermore, we show that the general coset ansaetze for the N=8 and N=7 algebras naturally lead to the coset spaces SO(8) x U(1)/SO(7) and SO(7) x U(1)/G 2 , respectively, as the additional consistent solutions for certain values of the central charge. The coset space SO(8)/SO(7) is the seven-sphere S 7 , whereas the space SO(7)/G 2 represents the seven-sphere with torsion, S 7 T . The division algebra of octonions and the associated triality properties of SO(8) play an essential role in all these realisations. We also comment on some possible applications of our results to string theory. (orig.)

    In May 2012, the World Health Assembly declared the completion of poliovirus eradication a programmatic emergency for global public health and called for a comprehensive polio endgame strategy. The Polio Eradication and Endgame Strategic Plan 2013-2018 was developed in response to this call and demands that all countries using Oral Polio Vaccine (OPV) only introduce at least 1 dose of Inactivated Polio Vaccine (IPV) into routine immunization schedules by the end of 2015. In November 2013, the Board of Gavi (the Vaccine Alliance) approved the provision of support for IPV introduction in the 72 Gavi-eligible countries. Following analytical work and stakeholder consultations, the IPV Immunization Systems Management Group (IMG) presented a proposal to provide exceptional financial support for IPV introduction to additional OPV-only using countries not eligible for Gavi support and that would otherwise not be able to mobilize the necessary financial resources within the Polio Eradication and Endgame Strategic Plan timelines. In June 2014, the Polio Oversight Board (POB) agreed to make available a maximum envelope of US $45 million toward supporting countries not eligible for Gavi funding. This article describes the design of the funding mechanism that was developed, its implementation and the lessons learned through this process. © The Author 2017.

    We construct N=2 supersymmetric nonlinear sigma models on the cotangent bundles over the non-compact exceptional Hermitian symmetric spaces M=E 6(−14) /SO(10)×U(1) and E 7(−25) /E 6 ×U(1). In order to construct them we use the projective superspace formalism which is an N=2 off-shell superfield formulation in four-dimensional space-time. This formalism allows us to obtain the explicit expression of N=2 supersymmetric nonlinear sigma models on the cotangent bundles over any Hermitian symmetric spaces in terms of the N=1 superfields, once the Kähler potentials of the base manifolds are obtained. We derive the N=1 supersymmetric nonlinear sigma models on the Kähler manifolds M. Then we extend them into the N=2 supersymmetric models with the use of the result in arXiv:1211.1537 developed in the projective superspace formalism. The resultant models are the N=2 supersymmetric nonlinear sigma models on the cotangent bundles over the Hermitian symmetric spaces M. In this work we complete constructing the cotangent bundles over all the compact and non-compact Hermitian symmetric spaces.

  4. Exceptional soft tissues preservation in a mummified frog-eating Eocene salamander

    Full Text Available Fossils are almost always represented by hard tissues but we present here the exceptional case of a three-dimensionally preserved specimen that was ‘mummified’ (likely between 40 and 34 million years ago in a terrestrial karstic environment. This fossil is the incomplete body of a salamander, Phosphotriton sigei, whose skeleton and external morphology are well preserved, as revealed by phase-contrast synchrotron X-ray microtomography. In addition, internal structures composed of soft tissues preserved in three dimensions are now identified: a lung, the spinal cord, a lumbosacral plexus, the digestive tract, muscles and urogenital organs that may be cloacal glands. These are among the oldest known cases of three-dimensional preservation of these organs in vertebrates and shed light on the ecology of this salamander. Indeed, the digestive tract contains remains of a frog, which represents the only known case of an extinct salamander that fed on a frog, an extremely rare type of predation in extant salamanders. These new data improve our scarce knowledge on soft tissue anatomy of early urodeles and should prove useful for future biologists and palaeontologists working on urodele evolutionary biology. We also suggest that the presence of bat guano and carcasses represented a close source of phosphorus, favouring preservation of soft tissues. Bone microanatomy indicates that P. sigei was likely amphibious or terrestrial, and was probably not neotenic.

  5. Convergent evolution in aquatic tetrapods: insights from an exceptional fossil mosasaur.

    Directory of Open Access Journals (Sweden)

    Johan Lindgren

    Full Text Available Mosasaurs (family Mosasauridae are a diverse group of secondarily aquatic lizards that radiated into marine environments during the Late Cretaceous (98-65 million years ago. For the most part, they have been considered to be simple anguilliform swimmers--i.e., their propulsive force was generated by means of lateral undulations incorporating the greater part of the body--with unremarkable, dorsoventrally narrow tails and long, lizard-like bodies. Convergence with the specialized fusiform body shape and inferred carangiform locomotory style (in which only a portion of the posterior body participates in the thrust-producing flexure of ichthyosaurs and metriorhynchid crocodyliform reptiles, along with cetaceans, has so far only been recognized in Plotosaurus, the most highly derived member of the Mosasauridae. Here we report on an exceptionally complete specimen (LACM 128319 of the moderately derived genus Platecarpus that preserves soft tissues and anatomical details (e.g., large portions of integument, a partial body outline, putative skin color markings, a downturned tail, branching bronchial tubes, and probable visceral traces to an extent that has never been seen previously in any mosasaur. Our study demonstrates that a streamlined body plan and crescent-shaped caudal fin were already well established in Platecarpus, a taxon that preceded Plotosaurus by 20 million years. These new data expand our understanding of convergent evolution among marine reptiles, and provide insights into their evolution's tempo and mode.

  6. An exceptional role for flowering plant physiology in the expansion of tropical rainforests and biodiversity.

    Movement of water from soil to atmosphere by plant transpiration can feed precipitation, but is limited by the hydraulic capacities of plants, which have not been uniform through time. The flowering plants that dominate modern vegetation possess transpiration capacities that are dramatically higher than any other plants, living or extinct. Transpiration operates at the level of the leaf, however, and how the impact of this physiological revolution scales up to the landscape and larger environment remains unclear. Here, climate modelling demonstrates that angiosperms help ensure aseasonally high levels of precipitation in the modern tropics. Most strikingly, replacement of angiosperm with non-angiosperm vegetation would result in a hotter, drier and more seasonal Amazon basin, decreasing the overall area of ever-wet rainforest by 80 per cent. Thus, flowering plant ecological dominance has strongly altered climate and the global hydrological cycle. Because tropical biodiversity is closely tied to precipitation and rainforest area, angiosperm climate modification may have promoted diversification of the angiosperms themselves, as well as radiations of diverse vertebrate and invertebrate animal lineages and of epiphytic plants. Their exceptional potential for environmental modification may have contributed to divergent responses to similar climates and global perturbations, like mass extinctions, before and after angiosperm evolution.

    Over the past several years, important strides have been made in demonstrating protonic ceramic fuel cells (PCFCs). Such fuel cells offer the potential of environmentally sustainable and cost-effective electric power generation. However, their power outputs have lagged behind predictions based on their high electrolyte conductivities. Here we overcome PCFC performance and stability challenges by employing a high-activity cathode, PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF), in combination with a chemically stable electrolyte, BaZr0.4Ce0.4Y0.1Yb0.1O3 (BZCYYb4411). We deposit a thin dense interlayer film of the cathode material onto the electrolyte surface to mitigate contact resistance, an approach which is made possible by the proton permeability of PBSCF. The peak power densities of the resulting fuel cells exceed 500 mW cm-2 at 500 °C, while also offering exceptional, long-term stability under CO2.

  8. Consequences of black exceptionalism? Interracial unions with blacks, depressive symptoms, and relationship satisfaction.

    2011-01-01

    Using data from Wave 4 (2008) of the National Longitudinal Study of Adolescent Health (N = 7,466), we examine potential consequences of black exceptionalism in the context of interracial relationships among nonblack respondents. While increasing racial diversity and climbing rates of interracial unions have fostered the notion that racial boundaries within the United States are fading, our results add to the accumulating evidence that racial/ethnic boundaries persist in U.S. society. Results suggest that among non-Black respondents there is more stigma and disapproval attached to relationships with Blacks than there are to relationships with members of other racial/ethnic groups. Specifically, our results indicate that nonblack individuals with black partners have significantly more depressive symptoms and less relationship satisfaction than their counterparts with nonblack partners, regardless of respondent race and whether the nonblack partner is the same versus a different race from the respondent. Further, the relationship between partner race and depressive symptoms is partially and significantly mediated by relationship satisfaction.

  9. Fractional statistics, exceptional preons, scalar dark matter, lepton number violation, neutrino masses, and hidden gauge structure

    1985-09-01

    A brief review is given of the basics of fractional statistics, which is based on the Dirac-Bohm-Aharanov effect. Some group theoretic aspects of exceptional preons are breifly described, and a theory is proposed containing hypercolor and hyperflavor with G/sub HC/ x G/sub HF/ = E(6) x E(6) and preons in (27,27). It is also suggested that the dark matter in the universe is due to a scalar field which transforms as a singlet under SU(3) x SU(2) x U(1) and interacts only via the Higgs boson. Some speculation is made on the existence and physical consequences of a SU(2) singet charged scalar field which couples to two lepton doublet, necessarily violating electron, muon, and tauon numbers. The Majorana masses of neutrinos are discussed as the result of breaking the total lepton number. Abelian gauge field hidden inside non-abelian gauge theory is briefly described in analogy to the electromagnetic potential term. 20 refs

  10. Exceptional retreat of Novaya Zemlya's marine-terminating outlet glaciers between 2000 and 2013

    J. R. Carr

    2017-09-01

    Full Text Available Novaya Zemlya (NVZ has experienced rapid ice loss and accelerated marine-terminating glacier retreat during the past 2 decades. However, it is unknown whether this retreat is exceptional longer term and/or whether it has persisted since 2010. Investigating this is vital, as dynamic thinning may contribute substantially to ice loss from NVZ, but is not currently included in sea level rise predictions. Here, we use remotely sensed data to assess controls on NVZ glacier retreat between 1973/76 and 2015. Glaciers that terminate into lakes or the ocean receded 3.5 times faster than those that terminate on land. Between 2000 and 2013, retreat rates were significantly higher on marine-terminating outlet glaciers than during the previous 27 years, and we observe widespread slowdown in retreat, and even advance, between 2013 and 2015. There were some common patterns in the timing of glacier retreat, but the magnitude varied between individual glaciers. Rapid retreat between 2000 and 2013 corresponds to a period of significantly warmer air temperatures and reduced sea ice concentrations, and to changes in the North Atlantic Oscillation (NAO and Atlantic Multidecadal Oscillation (AMO. We need to assess the impact of this accelerated retreat on dynamic ice losses from NVZ to accurately quantify its future sea level rise contribution.

    A fraction of the heavily reddened quasars require a reddening curve that is even steeper than that of the Small Magellanic Cloud. In this paper, we thoroughly characterize the anomalously steep reddening law in quasars via an exceptional example observed in IRAS 14026+4341. By comparing the observed spectrum to the quasar composite spectrum, we derive a reddening curve in the rest-frame wavelength range of 1200-10000 Å. It has a steep rise at wavelengths shorter than 3000 Å, but no significant reddening at longer wavelengths. The absence of dust reddening in the optical continuum is confirmed by the normal broad-line Balmer decrement (the Hα/Hβ ratio) in IRAS 14026+4341. The anomalous reddening curve can be satisfactorily reproduced with a dust model containing silicate grains in a power-law size distribution, dn(a)/da∝a –1.4 , truncated at a maximum size of a max = 70 nm. The unusual size distribution may be caused by the destruction of large 'stardust' grains by quasar activities or a different dust formation mechanism (i.e., the in situ formation of dust grains in quasar outflows). It is also possible that the analogies of the dust grains observed near the Galactic center are responsible for the steep reddening curve. In addition, we find that IRAS 14026+4341 is a weak emission-line quasar (i.e., PHL 1811 analogies) with heavy dust reddening and blueshifted broad absorption lines.

  12. Nonlocality and exceptional experiences: a study of genius, religious epiphany, and the psychic.

    2010-01-01

    Two hundred years of reductive materialism has failed to explain the extraordinary experiences we know as moments of genius, religious epiphany, and psychic insight. This paper proposes that these three experiences are in essence the same experience, differentiated only by intention and context. It reaches this conclusion based on well-conducted experimental research across the continuum of science--work that proposes a new interdependent model of consciousness that takes into consideration a nonlocal linkage or entanglement, as an aspect of consciousness not limited by space and time. The paper surveys some of the most important relevant research from quantum biology, physics, psychology, medicine, anthropology, and parapsychology. It proposes that more attention should be paid to the autobiographies, correspondence, and journals of men and women to whom history unequivocally accords the designation of genius, saint, or psychic, offering examples from these sources. And it presents comparisons between ethnohistorical material and spiritual traditions, suggesting they arrive at a similar worldview. Finally, it proposes that meditation research, some examples of which are cited, be seen in the context of psychophysical self-regulation, and that it offers one powerful avenue for producing these exceptional experiences. 2010 Elsevier Inc.

    The aim of this conference paper is to analyse relationships between strong changes of solar, geomagnetic and ionospheric physical parameters, and mortality by medical cause of death from diagnosis group Diseases of the nervous system by ICD-10 WHO. The aggregated daily number of deaths of 6 largest individual causes of death of group VI. Diseases of the nervous system on the occurrence of exceptional solar and geomagnetic events is investigated. Analysis is performed for the period of the solar cycles No. 23 and 24 (years 1994-2013) in the Czech Republic. The correlation between the intensity of mortality from diseases Multiple sclerosis, Epilepsy, Cerebral palsy, Parkinson disease, Secondary parkinsonism and Alzheimer disease and the solar, geomagnetic and ionospheric physical parameters is examined using stochastic method of graphical models of conditional dependences. We study the daily number of deaths separately for both sexes at the age groups under 39 and 40+. Differences are found for maximum solar activity and during the ascending and descending epoch of the solar cycles.

  14. Partial spontaneous anal expulsion of the right colon lipoma: An exceptional diagnostic circumstance

    Directory of Open Access Journals (Sweden)

    Fahmi Hamila

    Full Text Available Introduction: Lipomas are most common benign tumors of the colon. They are asymptomatic and fortuitously discovered on a morphological examination. Rarely, they cause complications such as acute intussusception. In this article, we reported an exceptional discovery mode of right colon lipoma. Case presentation: A 54-year-old woman has consulted for acute abdominal pain relieved by the anus emission of a fat ball that she brought back with her. Abdominal computed tomography scan showed the remaining part of a lipoma developed in her right colon. Laparoscopic right colonic resection was performed. Discussion: Colic lipomas are usually asymptomatic and surgical indication in these cases is debated, but it is indicated whenever complications occur such as acute intestinal intussusception. In this case, discovery mode was not considered as a complication because lipoma evacuation could have been complete. Radiological explorations and colonoscopy could evaluate the lesional state. When surgery is decided, intersecting therapeutic strategy of a short colonic resection guided by a colonization during colonoscopy should be considered. Conclusion: The spontaneous expulsion of a colonic lipoma is very rare. Our observation showed that this expulsion may be partial. +The changes that the lipoma undergoes can evoke a malignant cause. a supplement to take care of this eventuality is necessary.

  15. Smoking prevalence trends in Indigenous Australians, 1994-2004: a typical rather than an exceptional epidemic

    2009-10-01

    Full Text Available Abstract Background In Australia, national smoking prevalence has successfully fallen below 20%, but remains about 50% amongst Indigenous Australians. Australian Indigenous tobacco control is framed by the idea that nothing has worked and a sense of either despondency or the difficulty of the challenge. Methods This paper examines the trends in smoking prevalence of Australian Indigenous men and women aged 18 and over in three large national cross-sectional surveys in 1994, 2002 and 2004. Results From 1994 to 2004, Indigenous smoking prevalence fell by 5.5% and 3.5% in non-remote and remote men, and by 1.9% in non-remote women. In contrast, Indigenous smoking prevalence rose by 5.7% in remote women from 1994 to 2002, before falling by 0.8% between 2002 and 2004. Male and female Indigenous smoking prevalences in non-remote Australia fell in parallel with those in the total Australian population. The different Indigenous smoking prevalence trends in remote and non-remote Australia can be plausibly explained by the typical characteristics of national tobacco epidemic curves, with remote Indigenous Australia just at an earlier point in the epidemic. Conclusion Reducing Indigenous smoking need not be considered exceptionally difficult. Inequities in the distribution of smoking related-deaths and illness may be reduced by increasing the exposure and access of Indigenous Australians, and other disadvantaged groups with high smoking prevalence, to proven tobacco control strategies.

  16. The history of science as oxymoron: from scientific exceptionalism to episcience.

    Science.gov (United States)

    Alder, Ken

    2013-03-01

    This essay argues that historians of science who seek to embody our oxymoronic self-description must confront both contradictory terms that define our common enterprise--that is, both "history" and "science." On the history/methods side, it suggests that we embrace the heterogeneity of our institutional arrangements and repudiate the homogeneous disciplinary model sometimes advocated by Thomas Kuhn and followed by art history. This implies that rather than treating the history of science as an end in itself, we consider it a means to a variety of historical ends. think of ourselves as a tool-making community, and jettison moralistic assertions of scientific exceptionalism. To do so, this essay argues--on the science/subject side--that xe rebrand the subject of our historical inquiry as "episcience," a neologism that stands in relation to "science" as the new field of epigenetics does to the old genetics. Episcience encompasses both the material activities of the relevant sciences and their "surround" (environment, milieu, Umgebung) to reframe knowledge making to include the material processes that put science "in play" and make its findings matter beyond science. The essay concludes that "the history of science" is an oxymoron that makes sense to the extent that its practitioners acknowledge that the history of science is important not just because science is important, but because its history is.

    With nurses and unlicensed supportive personnel composing the greatest percentage of the workforce at any hospital, it is not surprising nursing leadership plays an increasing role in the attainment of financial goals. The nursing leadership team at one academic medical center reduced costs by more than $10 million over 4 years while outperforming national benchmarks on nurse-sensitive quality indicators. The most critical success factor in attaining exceptional financial performance is a personal and collective accountability to achieving outcomes. Whether it is financial improvement, advancing patient safety, or ensuring a highly engaged workforce, success will not be attained without thoughtful, focused leadership. The accountability model ensures there is a culture built around financial performance where nurses and leaders think and act, on a daily basis, in a manner necessary to understand opportunities, find answers, and overcome obstacles. While structures, processes, and tools may serve as the means to achieve a target, it is leadership's responsibility to set the right goal and motivate others.

    Desalination that produces clean freshwater from seawater holds the promise of solving the global water shortage for drinking, agriculture and industry. However, conventional desalination technologies such as reverse osmosis and thermal distillation involve large amounts of energy consumption, and the semipermeable membranes widely used in reverse osmosis face the challenge to provide a high throughput at high salt rejection. Here we find by comprehensive molecular dynamics simulations and first principles modeling that pristine graphyne, one of the graphene-like one-atom-thick carbon allotropes, can achieve 100% rejection of nearly all ions in seawater including Na + , Cl − , Mg 2+ , K + and Ca 2+ , at an exceptionally high water permeability about two orders of magnitude higher than those for commercial state-of-the-art reverse osmosis membranes at a salt rejection of ∼98.5%. This complete ion rejection by graphyne, independent of the salt concentration and the operating pressure, is revealed to be originated from the significantly higher energy barriers for ions than for water. This intrinsic specialty of graphyne should provide a new possibility for the efforts to alleviate the global shortage of freshwater and other environmental problems. (paper)

  20. Exceptional thermodynamics. The equation of state of G2 gauge theory

    2014-10-01

    We present a lattice study of the equation of state in Yang-Mills theory based on the exceptional G 2 gauge group. As is well-known, at zero temperature this theory shares many qualitative features with real-world QCD, including the absence of colored states in the spectrum and dynamical string breaking at large distances. In agreement with previous works, we show that at finite temperature this theory features a first-order deconfining phase transition, whose nature can be studied by a semi-classical computation. We also show that the equilibrium thermodynamic observables in the deconfined phase bear striking quantitative similarities with those found in SU(N) gauge theories: in particular, these quantities exhibit nearly perfect proportionality to the number of gluon degrees of freedom, and the trace anomaly reveals a characteristic quadratic dependence on the temperature, also observed in SU(N) Yang-Mills theories (both in four and in three spacetime dimensions). We compare our lattice data with analytical predictions from effective models, and discuss their implications for the deconfinement mechanism and high-temperature properties of strongly interacting, non-supersymmetric gauge theories. Our results give strong evidence for the conjecture that the thermal deconfining transition is governed by a universal mechanism, common to all simple gauge groups.

    Fossils are almost always represented by hard tissues but we present here the exceptional case of a three-dimensionally preserved specimen that was 'mummified' (likely between 40 and 34 million years ago) in a terrestrial karstic environment. This fossil is the incomplete body of a salamander, Phosphotriton sigei , whose skeleton and external morphology are well preserved, as revealed by phase-contrast synchrotron X-ray microtomography. In addition, internal structures composed of soft tissues preserved in three dimensions are now identified: a lung, the spinal cord, a lumbosacral plexus, the digestive tract, muscles and urogenital organs that may be cloacal glands. These are among the oldest known cases of three-dimensional preservation of these organs in vertebrates and shed light on the ecology of this salamander. Indeed, the digestive tract contains remains of a frog, which represents the only known case of an extinct salamander that fed on a frog, an extremely rare type of predation in extant salamanders. These new data improve our scarce knowledge on soft tissue anatomy of early urodeles and should prove useful for future biologists and palaeontologists working on urodele evolutionary biology. We also suggest that the presence of bat guano and carcasses represented a close source of phosphorus, favouring preservation of soft tissues. Bone microanatomy indicates that P. sigei was likely amphibious or terrestrial, and was probably not neotenic.

    Hummingbirds (Trochilidae) today have an exclusively New World distribution, but their pre-Pleistocene fossil record comes from Europe only. In this study, we describe an exceptionally preserved fossil hummingbird from the early Oligocene of southeastern France. The specimen is articulated, with a completely preserved beak and feathering. Osteological characters allow to identify it as Eurotrochilus sp. This genus is a stem group representative of Trochilidae and was recently described from the early Oligocene of southern Germany. The new fossil reveals that these European Trochilidae were remarkably modern in size, skeletal proportions and the shape of the wing, tail and beak and hyoid bones. These features confirm the early acquisition of the abilities of hovering and nectarivory in hummingbirds, probably before the Oligocene. In several morphological characteristics, they resemble members of the ‘true hummingbirds’ (subfamily Trochilinae) and differ from hermits (Phaethornithinae). These features, which include a short and square tail and a moderately long, almost straight beak, appear to be primitive within the family Trochilidae.

    Tendinous and subcutaneous xanthomas are most commonly associated with primary hyperlipidemia. Xanthomatosis caused by cholesterol deposition can be a high risk marker for cardiovascular disease related to premature atherosclerosis; thus, early recognition of this diagnosis may reduce mortality and morbidity. Achilles tendon involvement is most common, followed by the extensor tendons of the hand and elbow. We present an exceptional case of tendinous and tuberous xanthomas, with intraoperative and histologic correlation, in a 34-year-old female manifesting with xanthomatous deposits of nearly all ankle tendons, plantar aponeurosis, extensor tendons of the hands, and various locations within the integumentum. To the authors' knowledge, only four studies to date have focused specifically on imaging findings of multifocal xanthomas. Thus, the radiographic and MR imaging descriptions of xanthomas in this report further add to the existing literature by helping to identify imaging characteristics of this multifocal systemic disease. The diagnosis of this condition should alert the physician to the presence of a dyslipidemia that can be treated with dietary modifications and/or drug therapy. (orig.)

    We sought to characterize persons who requested to opt out of an exception from informed consent (EFIC) cardiac arrest trial and their reasons for opting out. At one site of a multi-site, out-of-hospital, cardiac arrest EFIC trial (September 2007 - June 2009), persons who did not want to participate in the study could request an opt-out "NO STUDY" bracelet to prevent trial enrollment. We surveyed all persons who requested a bracelet by phone interview, web or mail. Opt-out bracelets were advertised in all public communication about the study, including community consultation and public disclosure efforts. Survey questions included demographics, Likert scale items about attitudes toward the trial and research in general, plus open-ended questions. We used descriptive statistics for standardized questions and qualitative analysis to identify common themes from open-ended questions. Sixty bracelets were requested by 50 individuals. Surveys were completed by 46 persons (92% response rate). Seventy percent of respondents agreed emergency research is important, but 87% objected to any research without consent. In the qualitative analysis, 5 overlapping themes emerged: questioning the ethics of EFIC research; concerns about how the study would impact end-of-life preferences; subjective emotions including sarcasm, anger, and allusions to past unethical research; negative reference to unrelated public health controversies; and objections to the study protocol based on misinformation. A primary reason for opting out from this EFIC trial was opposition to all research without informed consent, despite stated support for emergency research. Understanding the demographics and beliefs of persons opting out may aid researchers planning EFIC studies and help provide clarity in future EFIC-related community education efforts.

    2014-08-01

    Full Text Available In the context of Israel’s declared permanent state of exception, this article focuses on the legal protection awarded to the Palestinian populations under Israeli control. To broaden the discussion over Palestinian people’s rights, which generally focuses on the confiscation of land and the right to return, the author consciously focuses on anti-terrorism and security measures, which contribute to the creation of what the International Court of Justice has defined as an ‘associated regime’ of occupation. The article is divided into three parts. In the first part, the author discusses Israel’s domestic obligations towards Palestinians (arguing the case of both Palestinian citizens of Israel, and Palestinian residents and their de jure and de facto discrimination. The second part discusses the applicability of humanitarian law, specifically the applicability of the Fourth Geneva Convention. This section discusses the applicability of the Convention to both territories and people under Israeli control. The third part discusses the applicability of international human rights law to all territories under Israeli control and delves into the issue of the mutual relationship between the two international legal regimes in the territories under occupation. The article posits that Israel’s rationale for the non-applicability of such legislation to the Palestinian territories and populations it controls constitutes a form of ‘alternative legality’. The article concludes that Israel’s disproportionate application of security practices and anti-terrorism measures to the Palestinian segment of its population violates Palestinian rights protected under Israel’s domestic and international legal obligations.

    The Medicare Primary Care Exception (PCE) allows residents to see and bill for less-complex patients independently in the primary care setting, requiring attending physicians only to see patients for higher-level visits and complete physical exams in order to bill for them as such. Primary care residencies apply the PCE in various ways. We investigated the impact of the PCE on resident coding practices. Family medicine residency directors in a five-state region completed a survey regarding interpretation and application of the PCE, including the number of established patient evaluation and management codes entered by residents and attending faculty at their institution. The percentage of high-level codes was compared between residencies using chi-square tests. We analyzed coding data for 125,016 visits from 337 residents and 172 faculty physicians in 15 of 18 eligible family medicine residencies. Among programs applying the PCE criteria to all patients, residents billed 86.7% low-mid complexity and 13.3% high-complexity visits. In programs that only applied the PCE to Medicare patients, residents billed 74.9% low-mid complexity visits and 25.2% high-complexity visits. Attending physicians coded more high-complexity visits at both types of programs. The estimated revenue loss over the 1,650 RRC-required outpatient visits was $2,558.66 per resident and $57,569.85 per year for the average residency in our sample. Residents at family medicine programs that apply the PCE to all patients bill significantly fewer high-complexity visits. This finding leads to compliance and regulatory concerns and suggests significant revenue loss. Further study is required to determine whether this discrepancy also reflects inaccuracy in coding.

  7. Exceptionally High Creatine Kinase (CK) Levels in Multicausal and Complicated Rhabdomyolysis: A Case Report.

    2017-07-04

    BACKGROUND Rhabdomyolysis is a syndrome caused by muscle breakdown. It can be caused by traumatic as well as non-traumatic factors such as drugs, toxins, and infections. Although it has been initially associated with only traumatic causes, non-traumatic causes now appear to be at least 5 times more frequent. In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications. We present the case of a patient with exceptionally massive rhabdomyolysis with unusually high CK levels (nearly 1 million) caused by combined etiologic factors and complicated with acute renal failure. CASE REPORT A 36-year-old African American male patient with no significant past medical history and a social history of cocaine and alcohol abuse presented with diarrhea and generalized weakness of 2 days' duration. He was found to be febrile, tachycardic, tachypneic, and hypoxic. The patient was subsequently intubated and admitted to the medical ICU. Laboratory work-up showed acute renal failure with deranged liver functions test results, and elevated creatine kinase of 701,400 U/L. CK levels were subsequently too high for the lab to quantify. Urine legionella testing was positive for L. pneumophilia serogroup 1 antigen and urine toxicology was positive for cocaine. The patient had a protracted course in the ICU. He was initially started on CVVH, and later received intermittent hemodialysis for about 1 month. CONCLUSIONS In the presence of multiple etiologic factors, rhabdomyolysis can be massive with resultant significant morbidity. Clinicians should have a high index of suspicion for rhabdomyolysis in the presence of multiple factors, as early recognition of this diseases is very important in the prevention and active management of life-threatening conditions.

  8. Hierarchical assembly strategy and multiscale structural origin of exceptional mechanical performance in nacre

    Science.gov (United States)

    Huang, Zaiwang

    Nacre (mother of pearl) is a self-assembled hierarchical nanocomposite in possession of exquisite multiscale architecture and exceptional mechanical properties. Previous work has shown that the highly-ordered brick-mortar-like structure in nacre is assembled via epitaxial growth and the aragonite platelets are pure single-crystals. Our results challenge this conclusion and propose that nacre's individual aragonite platelets are constructed with highly-aligned aragonite nanoparticles mediated by screw dislocation and amorphous aggregation. The underlying physics mechanism why the aragonite nanoparticles choose highly-oriented attachment as its crystallization pathway is rationalized in terms of thermodynamics. The aragonite nanoparticle order-disorder transformation can be triggered by high temperature and mechanical deformation, which in turn confirms that the aragonite nanoparticles are basic building blocks for aragonite platelets. Particularly fascinating is the fracture toughness enhancement of nacre through exquisitely collecting mechanically inferior calcium carbonate (CaCO3) and biomolecules. The sandwich-like microarchitecture with a geometrically staggered arrangement can induce crack deflection along its biopolymer interface, thus significantly enhancing nacre's fracture toughness. Our new findings ambiguously demonstrate that, aside from crack deflection, the advancing crack can invade aragonite platelet, leaving a zigzag crack propagation pathway. These unexpected experimental observations disclose, for the first time, the inevitable structural role of aragonite platelets in enhancing nacre's fracture toughness. Simultaneously, the findings that the crack propagates in a zigzag manner within individual aragonite platelets overturn the previously well-established wisdom that considers aragonite platelets as brittle single-crystals. Moreover, we investigated the dynamical mechanical response of nacre under unixial compression. Our results show that the

    PH-797804 is a diarylpyridinone inhibitor of p38{alpha} mitogen-activated protein (MAP) kinase derived from a racemic mixture as the more potent atropisomer (aS), first proposed by molecular modeling and subsequently confirmed by experiments. On the basis of structural comparison with a different biaryl pyrazole template and supported by dozens of high-resolution crystal structures of p38{alpha} inhibitor complexes, PH-797804 is predicted to possess a high level of specificity across the broad human kinase genome. We used a structural bioinformatics approach to identify two selectivity elements encoded by the TXXXG sequence motif on the p38{alpha} kinase hinge: (i) Thr106 that serves as the gatekeeper to the buried hydrophobic pocket occupied by 2,4-difluorophenyl of PH-797804 and (ii) the bidentate hydrogen bonds formed by the pyridinone moiety with the kinase hinge requiring an induced 180{sup o} rotation of the Met109-Gly110 peptide bond. The peptide flip occurs in p38{alpha} kinase due to the critical glycine residue marked by its conformational flexibility. Kinome-wide sequence mining revealed rare presentation of the selectivity motif. Corroboratively, PH-797804 exhibited exceptionally high specificity against MAP kinases and the related kinases. No cross-reactivity was observed in large panels of kinase screens (selectivity ratio of >500-fold). In cellular assays, PH-797804 demonstrated superior potency and selectivity consistent with the biochemical measurements. PH-797804 has met safety criteria in human phase I studies and is under clinical development for several inflammatory conditions. Understanding the rationale for selectivity at the molecular level helps elucidate the biological function and design of specific p38{alpha} kinase inhibitors.

    Polymer nanocomposites are increasingly important in food packaging sectors. Biopolymer pullulan is promising in manufacturing packaging films or coatings due to its excellent optical clarity, mechanical strength, and high water-solubility as compared to other biopolymers. This work aims to enhance its oxygen barrier properties and overcome its intrinsic brittleness by utilizing two-dimensional planar graphene oxide (GO) nanoplatelets. It has been found that the addition of only 0.2 wt% of GO enhanced the tensile strength, Young’s modulus, and elongation at break of pullulan films by about 40, 44 and 52%, respectively. The light transmittance at 550 nm of the pullulan/GO films was 92.3% and haze values were within 3.0% threshold, which meets the general requirement for food packaging materials. In particular, the oxygen permeability coefficient of pullulan was reduced from 6337 to 2614 mL μm m-2 (24 h-1) atm-1 with as low as 0.05 wt% of GO loading and further to 1357 mL μm m-2 (24 h-1) atm-1 when GO concentration reached 0.3 wt%. The simultaneous improvement of the mechanical and oxygen barrier properties of pullulan was ascribed to the homogeneous distribution and prevalent unidirectional alignment of GO nanosheets, as determined from the characterization and theoretical modelling results. The exceptional oxygen barrier properties of pullulan/GO nanocomposites with enhanced mechanical flexibility and good optical clarity will add new values to high performance food packaging materials.

    Here we report on a Holocene inter-dune site close to Walvis Bay (Namibia) which contains exceptionally well-preserved children's footprints. The footprint surface is dated using Optically Stimulated Luminescence (OSL) methods to approximately 1.5 ka. These dates are compared to those obtained at nearby footprint sites and used to verify a model of diachronous footprint surfaces and also add to the archaeological data available for the communities that occupied these near-coastal areas during the Holocene. This model of diachronous footprint surfaces has implications for other soft-sediment footprint sites such as the 1.5 Ma old footprints at Ileret (Kenya). The distribution of both human and animal tracks, is consistent with the passage of small flock of small ungulates (probably sheep/goats) followed by a group of approximately 9 ± 2 individuals (children or young adults). Age estimates from the tracks suggest that some of the individuals may have been as young as five years old. Variation in track topology across this sedimentologically uniform surface is explained in terms of variations in gait and weight/stature of the individual print makers and is used to corroborate a model of footprint morphology developed at a nearby site. The significance of the site within the literature on human footprints lies in the quality of the track preservation, their topological variability despite a potentially uniform substrate, and the small size of the tracks, and therefore the inferred young age of the track-makers. The site provides an emotive insight into the life of the track-makers.

    Extratropical cyclones dominate autumn and winter weather over Western Europe and particularly over the Iberian Peninsula. Intense, high-impact storms are one of the major weather risks in the region, mostly due to the simultaneous occurrence of high winds and extreme precipitation events. These intense extratropical cyclones may result in windstorm damage, flooding and coastal storm surges, with large societal impacts. In Portugal, due to the extensive human use of coastal areas, the natural and built coastal environments have been amongst the most affected. In this work several historical winter storms that adversely affected the Western Iberian Peninsula are studied in detail in order to contribute to an improved assessment of the characteristics of these events. The diagnosis has been performed based on instrumental daily precipitation and wind records, on satellite images, on reanalysis data and through model simulations. For several examples the synoptic evolution and upper-level dynamics analysis of physical processes controlling the life cycle of extratropical storms associated with the triggering of the considered extreme events has also been accomplished. Furthermore, the space-time variability of the exceptionally severe storms affecting Western Iberia over the last century and under three climate scenarios (the historical simulation, the RCP4.5 and RCP8.5 scenarios) is presented. These studies contribute to improving the knowledge of atmospheric dynamics controlling the life cycle of midlatitude storms associated to severe weather (precipitation and wind) in the Iberian Peninsula.

  14. Estimating Exceptionally Rare Germline and Somatic Mutation Frequencies via Next Generation Sequencing.

    Directory of Open Access Journals (Sweden)

    Jordan Eboreime

    Full Text Available We used targeted next generation deep-sequencing (Safe Sequencing System to measure ultra-rare de novo mutation frequencies in the human male germline by attaching a unique identifier code to each target DNA molecule. Segments from three different human genes (FGFR3, MECP2 and PTPN11 were studied. Regardless of the gene segment, the particular testis donor or the 73 different testis pieces used, the frequencies for any one of the six different mutation types were consistent. Averaging over the C>T/G>A and G>T/C>A mutation types the background mutation frequency was 2.6x10-5 per base pair, while for the four other mutation types the average background frequency was lower at 1.5x10-6 per base pair. These rates far exceed the well documented human genome average frequency per base pair (~10-8 suggesting a non-biological explanation for our data. By computational modeling and a new experimental procedure to distinguish between pre-mutagenic lesion base mismatches and a fully mutated base pair in the original DNA molecule, we argue that most of the base-dependent variation in background frequency is due to a mixture of deamination and oxidation during the first two PCR cycles. Finally, we looked at a previously studied disease mutation in the PTPN11 gene and could easily distinguish true mutations from the SSS background. We also discuss the limits and possibilities of this and other methods to measure exceptionally rare mutation frequencies, and we present calculations for other scientists seeking to design their own such experiments.

    We have previously reported genome-scale short tandem repeats (STRs) in the core promoter interval (i.e. -120 to +1 to the transcription start site) of protein-coding genes that have evolved identically in primates vs. non-primates. Those STRs may function as evolutionary switch codes for primate speciation. In the current study, we used the Ensembl database to analyze the 5' untranslated region (5' UTR) between +1 and +60 of the transcription start site of the entire human protein-coding genes annotated in the GeneCards database, in order to identify "exceptionally long" STRs (≥5-repeats), which may be of selective/adaptive advantage. The importance of this critical interval is its function as core promoter, and its effect on transcription and translation. In order to minimize ascertainment bias, we analyzed the evolutionary status of the human 5' UTR STRs of ≥5-repeats in several species encompassing six major orders and superorders across mammals, including primates, rodents, Scandentia, Laurasiatheria, Afrotheria, and Xenarthra. We introduce primate-specific STRs, and STRs which have expanded from mouse to primates. Identical co-occurrence of the identified STRs of rare average frequency between 0.006 and 0.0001 in primates supports a role for those motifs in processes that diverged primates from other mammals, such as neuronal differentiation (e.g. APOD and FGF4), and craniofacial development (e.g. FILIP1L). A number of the identified STRs of ≥5-repeats may be human-specific (e.g. ZMYM3 and DAZAP1). Future work is warranted to examine the importance of the listed genes in primate/human evolution, development, and disease. Copyright © 2015 Elsevier B.V. All rights reserved.

    Modern representatives of Polychelida (Polychelidae) are considered to be entirely blind and have largely reduced eyes, possibly as an adaptation to deep-sea environments. Fossil species of Polychelida, however, appear to have well-developed compound eyes preserved as anterior bulges with distinct sculpturation. We documented the shapes and sizes of eyes and ommatidia based upon exceptionally preserved fossil polychelidans from Binton (Hettangian, United-Kingdom), Osteno (Sinemurian, Italy), Posidonia Shale (Toarcian, Germany), La Voulte-sur-Rhône (Callovian, France), and Solnhofen-type plattenkalks (Kimmeridgian-Tithonian, Germany). For purposes of comparison, sizes of the eyes of several other polychelidans without preserved ommatidia were documented. Sizes of ommatidia and eyes were statistically compared against carapace length, taxonomic group, and outcrop. Nine species possess eyes with square facets; Rosenfeldia oppeli (Woodward, 1866), however, displays hexagonal facets. The sizes of eyes and ommatidia are a function of carapace length. No significant differences were discerned between polychelidans from different outcrops; Eryonidae, however, have significantly smaller eyes than other groups. Fossil eyes bearing square facets are similar to the reflective superposition eyes found in many extant decapods. As such, they are the earliest example of superposition eyes. As reflective superposition is considered plesiomorphic for Reptantia, this optic type was probably retained in Polychelida. The two smallest specimens, a Palaeopentacheles roettenbacheri (Münster, 1839) and a Hellerocaris falloti (Van Straelen, 1923), are interpreted as juveniles. Both possess square-shaped facets, a typical post-larval feature. The eye morphology of these small specimens, which are far smaller than many extant eryoneicus larvae, suggests that Jurassic polychelidans did not develop via giant eryoneicus larvae. In contrast, another species we examined, Rosenfeldia oppeli

    Published 8 months after the Fukushima Dai-ichi accident, this special issue of Le Monde newspaper takes stock of the nuclear question. Prior to the Fukushima accident, the civil nuclear industry experienced two other major accidents: Three Miles Island (US, 1979) with limited and controlled impacts, and Chernobyl (USSR, 1986) with enormous impacts. The recent Japanese catastrophe has revived the questions concerning this risky technology. However, according to the IAEA, the civil nuclear energy should continue to develop in the future but in a more moderate way. Germany announced in June 2011 the shutdown of its last reactor by 2022, while France remained an exception until the Fukushima accident with a large political consensus among the general public in favor of nuclear energy. The nuclear phasing out or the energy transition is a complex question which is explored in this special issue. Content: 1 - The nuclear world: a moderate growth of the nuclear industry; interview of Mohamed ElBaradei, former head of IAEA; 441 reactors in operation in the world in January 2011; France has chosen the all-nuclear option; critics: a 'costly, unadapted, useless' nuclear program; interview of Valery Giscard d'Estaing, former French President; the nuclear industry actors; nuclear dismantling: a what cost?; how to manage the 250.000 tons of spent fuels; 2 - A risky technology: radioactivity measurement and effects; how to manage contaminations; four generations of reactors; ITER: a solar project; imagining the unimaginable and anticipating the worse; the wake up of a dozed off fear; the most important accidents: the progress of the three main nuclear catastrophes, the human mistake of Three Mile Island, the days after the Chernobyl accident, in the dead cities around Fukushima; interview of Kenzaburo Oe (Japanese writer); the Blayais power plant to the test; 3 - The energy transition: is France capable to abandon nuclear energy?; Germany is going to re-launch gas- and coal

    Full Text Available BackgroundSleep patterns such as longer sleep duration or napping are associated with poor health outcomes. Although centenarians and their offspring demonstrate a delayed onset of age-related diseases, it is not known whether they have healthier sleep patterns or are protected against the negative effects of sleep disturbances.MethodsData on sleep patterns and health history were collected from Ashkenazi Jewish subjects of the Longevity Genes Project using standardized questionnaires. Participants included individuals with exceptional longevity (centenarians with preserved cognition (n = 348, median age 97 years, their offspring (n = 513, median age 69 years, and controls (n = 199 age-matched to the offspring. Centenarians reported on their sleep patterns at age 70, while the offspring and controls on their current sleep patterns. Biochemical parameters were measured at baseline. Models were adjusted for age, sex, BMI, and use of sleep medication.ResultsThe offspring and controls reported similar sleep patterns, with 33% sleeping ≥8 h and 17% napping in each group. At age 70, centenarians were more likely to have slept ≥8 h (55% and to have napped (28% compared with offspring and controls, p < 0.01. Among centenarians, no association was noted between sleep patterns and health outcomes. Sleeping for ≥8 h was associated with lower high-density lipoprotein cholesterol levels in the offspring and controls, and with insulin resistance in the offspring, but not with diabetes. Napping was associated with insulin resistance among the controls (p < 0.01, but not the offspring. Controls, but not offspring, who napped were 2.79 times more likely to have one or more of the following diseases: hypertension, myocardial infarction, stroke, or diabetes (OR 2.79, 95% CI 1.08–7.21, p = 0.04.ConclusionDespite being more likely to exhibit risky sleep patterns at age 70 compared with the offspring and controls, the

    The synoptic evolution and dynamical characteristics of storm "Klaus" (23 and 24 January 2009) are analysed. "Klaus" was an extratropical cyclone which developed over the subtropical North Atlantic Ocean on the 21st January 2009, then moved eastward embedded in the strong westerly flow and experienced a notorious strengthening on the 23rd January. The storm moved into the Bay of Biscay and deepened further before hitting Northern Spain and Southwestern France with gusts of up to 198 km/h. Afterwards, it steered southeastwards across Southern France into Northern Italy and the Adriatic. "Klaus" was the most intense and damaging wind storm in the region in a decade, provoked more than 20 casualties and insured losses of several billion Euros. The evolution of "Klaus" is analysed using two standard cyclone detecting and tracking schemes: a) the vorticity maxima based algorithm originally developed by Murray and Simmonds [1991], adapted for Northern Hemisphere cyclone characteristics [Pinto et al. 2005]; and b) the pressure minima based algorithm first developed for the Mediterranean region [Trigo et al. 1999; 2002] and later extended to a larger Euro-Atlantic region [Trigo 2006]. Additionally, the synoptic and mesoscale features of the storm are analysed. The vorticity based method detects the storm earlier than the pressure minima one. Results show that both tracks exhibited similar features and positions throughout almost all of their lifecycles, with minor discrepancies being probably related to different ways of both methods handling the spatio-temporal evolution of multiple candidates for cyclonic centres. In its strengthening phase, "Klaus" presents deepening rates above 37 hPa/24h, a value that after geostrophically adjusted to the reference latitude of 60°N increases to 44 hPa/24h, implying an exceptional event with bomb characteristics. During maximum intensity change within 24 hours was 1.165hPa/(deglat)2. References: Murray RJ, Simmonds I (1991) Aust

    The US Food and Drug Administration and the Department of Health and Human Services outline regulations allowing an exception from informed consent (EFIC) for research conducted in an emergency setting. Acute care clinical trials using EFIC must include community consultation and public disclosure (CC/PD) activities. We describe our experience using social media to facilitate the CC/PD process in two trauma resuscitation clinical trials. We conducted local CC/PD activities for two multicenter trauma clinical trials, Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) and Prehospital Tranexamic Acid Use for Traumatic Brain Injury (ROC-TXA). As part of the CC/PD process, we developed research study advertisements using the social media Web site Facebook. The Facebook advertisements directed users to a regional study Web site that contained trial information. We targeted the advertisements to specific demographic users, in specific geographic areas. We analyzed the data using descriptive statistics. During the study periods, the PROPPR Facebook advertisement was displayed 5,001,520 times (12 displays per target population) with 374 individuals selecting the advertisement. The ROC-TXA Facebook advertisement was displayed 3,806,448 times (8 per target population) with 790 individuals selecting the advertisement. Respondents to both Facebook advertisements were mostly male (52.6%), with the highest proportion between the ages 15 years and 24 years (28.2%). Collectively, 26.9% of individuals that clicked on the Facebook advertisement spent more than 3 minutes on the study Web site (3-49 minutes). Commonly accessed Web pages were "contact us" (PROPPR, 5.5%; ROC-TXA, 7.7%), "study-specific FAQs" (PROPPR, 2.4%; ROC-TXA, 6.7%), and "opt out of research" (PROPPR, 2.5%; ROC-TXA, 3.8%). Of 51 total individuals viewing the opt out of research information (PROPPR, 19; ROC-TXA, 32), time spent on that specific page was modest (PROPPR, 62 seconds; ROC-TXA, 55 seconds

    Emergency exception to informed consent regulation was introduced to provide a venue to perform research on subjects in emergency situations before obtaining informed consent. For a study to proceed, institutional review boards (IRBs) need to determine if the regulations have been met. To determine IRB members' experience reviewing research protocols using emergency exception to informed consent. This qualitative research used semistructured telephone interviews of 10 selected IRB members from around the US in the fall of 2003. IRB members were chosen as little is known about their views of exception to consent, and part of their mandate is the protection of human subjects in research. Interview questions focused on the length of review process, ethical and legal considerations, training provided to IRB members on the regulations, and experience using community consultation and notification. Content analysis was performed on the transcripts of interviews. To ensure validity, data analysis was performed by individuals with varying backgrounds: three emergency physicians, an IRB member and a layperson. Respondents noted that: (1) emergency exception to informed consent studies require lengthy review; (2) community consultation and notification regulations are vague and hard to implement; (3) current regulations, if applied correctly, protect human subjects; (4) legal counsel is an important aspect of reviewing exception to informed-consent protocols; and (5) IRB members have had little or no formal training in these regulations, but are able to access materials needed to review such protocols. This preliminary study suggests that IRB members find emergency exception to informed consent studies take longer to review than other protocols, and that community consultation and community notification are the most difficult aspect of the regulations with which to comply but that they adequately protect human subjects.

    Exceptional aging, defined as reaching age 85 years, shows geographic inequalities that may depend on local environmental conditions. Links between particulate pollution-a well-recognized environmental risk factor-and exceptional aging have not been investigated.

Communities with the most exceptional aging have low ambient air pollution and low rates of smoking, poverty, and obesity. Improvements in these determinants may contribute to increasing exceptional aging. Citation: Baccarelli AA, Hales N, Burnett RT, Jerrett M, Mix C, Dockery DW, Pope CA III. 2016.

  5. NASA's Astro-Venture Engages Exceptional Students in Earth System Science Using Inquiry

    2003-12-01

    Astro-Venture is an educational, interactive, multimedia Web environment highlighting NASA careers and astrobiology research in the areas of Astronomy, Geology, Biology and Atmospheric Sciences. Students in grades 5-8 role-play NASA careers, as they search for and design a planet with the necessary characteristics for human habitation. Astro-Venture uses online multimedia activities and off-line inquiry explorations to engage students in guided inquiry aligned with the 5 E inquiry model. This model has proven to be effective with exceptional students. Students are presented with the intellectual confrontation of how to design a planet and star system that would be able to meet their biological survival needs. This provides a purpose for the online and off-line explorations used throughout the site. Students first explore "what" conditions are necessary to support human habitability by engaging in multimedia training modules, which allow them to change astronomical, atmospheric, geological and biological aspects of the Earth and our star system and to view the effects of these changes on Earth. By focusing on Earth, students draw on their prior knowledge, which helps them to connect their new knowledge to their existing schema. Cause and effect relationships of Earth provide a concrete model from which students can observe patterns and generalize abstract results to an imagined planet. From these observations, students draw conclusions about what aspects allowed Earth to remain habitable. Once students have generalized needed conditions of "what" we need for a habitable planet, they conduct further research in off-line, standards-based classroom activities that also follow the inquiry model and help students to understand "why" we need these conditions. These lessons focus on standards-based concepts such as states of matter and the structure and movement of the Earth's interior. These lessons follow the inquiry structure commonly referred to as the five E's as

The third, and most exceptional, manifestation is that the idealized structural reorganization accompanying the conceptual transformations Ag 2 (CH 3 CN) 8 (Y) → Ag 2 (CH 3 CN) 5 (Y) → Ag 2 (CH 3 CN) 4 (Y) involve close-packed layers of Y 2- anions that sandwich the Ag(CH 3 CN) 4 + complexes splitting into staggered flat ribbons of interconnected (Y 2- ) 3 triangles that surround the Ag 2 (CH 3 CN) 5 2+ complexes on four sides, conceptually re-forming close-packed layers of anions that sandwich the Ag(CH 3 CN) 2 + complexes. The interconnected (Y 2- ) 3 triangle lattice of anions in Ag 2 (CH 3 CN) 5 (Y) may be the first example of this structure type.

  11. Moral absolutism and the double-effect exception: reflections on Joseph Boyle's Who is entitled to double effect?

    Science.gov (United States)

    Donagan, A

    1991-10-01

    Joseph Boyle raises important questions about the place of the double-effect exception in absolutist moral theories. His own absolutist theory (held by many, but not all, Catholic moralists), which derives from the principles that fundamental human goods may not be intentionally violated, cannot dispense with such exceptions, although he rightly rejects some widely held views about what they are. By contrast, Kantian absolutist theory, which derives from the principle that lawful freedom must not be violated, has a corollary--that it is a duty, where possible, to coerce those who try to violate lawful freedom--which makes superfluous many of the double-effect exceptions Boyle allows. Other implications of the two theories are contrasted. Inter alia, it is argued that, in Boyle's theory, that a violation of a fundamental human good can be viewed as a cost proportionate to a benefit obtained, cannot yield a double-effect exception to the prohibition of intentionally violating that good, because paying a cost cannot be unintentional.

    Many studies have reported that twice-exceptional (2e) students were vulnerable in psychological traits and exhibited low-academic self-concept and academic self-efficacy. Such vulnerability may cause their academic failures. This study applied interpretative phenomenological analysis (IPA), a qualitative approach to investigate the perceptions of…

    Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant (e.g., the notochord) are rarely preserved (even where carbonaceous components survive), and decay-prone structures (e.g., nervous systems) can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. © 2017 The Authors.

    Usher syndrome is defined by the association of a progressive or non-progressive congenital sensorineural hearing loss with variable severity and a gradually blinding pigmentary retinopathy. Von Recklinghausen neurofibromatosis or Neurofibromatosis type 1 is the major clinically form of neurofibromatosis which occurs in approximately 90% of cases. Both types of disease are genetic in origin with very low prevalence. The probability of co-occurrence of these diseases in a single individual is exceptional. Inbreeding, as well as all genetic diseases, increases quite significantly the probability of their occurrence. Consanguineous marriages are still widespread in Maghreb and in some regions of the western African. This observation reports an exceptional case of this association in a 40-year-old man of Mauritanian origin born from a consanguineous union.

    The short note gives a derivation for a new E12 exceptional Lie group corresponding to affine KAC-Moody algebra. We derive the dimension of the group by intersectionally embedding the intrinsic dimension of E8 namely D(E8) = 57 into the 12 spacetime dimensions of F theory and finding that Dim E12 = D(E8) (DF) + 1 = (57)(12) + 1 = 685

    Politics, public discourse, and legislation restricting abortion has settled on a moderate orthodoxy: restrict abortion, but leave exceptions for pregnancies that result from rape and incest. I challenge that consensus and suggest it may be much harder to defend than those who support the compromise think. From both Pro-Life and Pro-Choice perspectives, there are good reasons to treat all abortions as equal. © 2015 American Society of Law, Medicine & Ethics, Inc.

    Time-asymmetric state-evolution properties while encircling an exceptional point are presently of great interest in search of new principles for controlling atomic and optical systems. Here, we show that encircling-an-exceptional-point interactions that are essentially reciprocal in the linear interaction regime make a plausible nonlinear integrated optical device architecture highly nonreciprocal over an extremely broad spectrum. In the proposed strategy, we describe an experimentally realizable coupled-waveguide structure that supports an encircling-an-exceptional-point parametric evolution under the influence of a gain saturation nonlinearity. Using an intuitive time-dependent Hamiltonian and rigorous numerical computations, we demonstrate strictly nonreciprocal optical transmission with a forward-to-backward transmission ratio exceeding 10 dB and high forward transmission efficiency (∼100%) persisting over an extremely broad bandwidth approaching 100 THz. This predicted performance strongly encourages experimental realization of the proposed concept to establish a practical on-chip optical nonreciprocal element for ultra-short laser pulses and broadband high-density optical signal processing.

  17. The exceptional clauses in the contractual activity on the public administration: freedom of choice or legislative imposition

    Full Text Available The contracting activity of public administration in Colombia has generally allowed, by order of constitutional and legislative norms, the application of the principle of autonomy, so that those subjects within a public legal transaction can build and establish the conditions governing their contract. The scope of the principle of autonomy must be analyzed and subjected to reflection, especially considering the institution of exception clauses in common law used by State agencies and their legal relationship with contractors. The existence of exception clauses has been justified by the interests of the State (and in particular the public interest without strictly analyzing the essence of the figure. The application of this institution in contractual relations of the State has advanced greatly, but it is still uncertain if the true nature of the figure is caused by the autonomy of the parties in order to celebrate the contract, or if it comes as privileges conferred and imposed by the legislator as a way to concise the principle of legality. This paper concludes that exception clauses in common law, clearly applied in contractual activity within public administration, consist of special privileges imposed by the legislator to State entities, and are therefore opposed to the essence of the clause and the principle of autonomy.

    Since 1998, there have been some speculations about future transport of significant quantities and concentrations of other actinide nuclides than the four currently listed in the regulation for the safe transport of the radioactive material. Therefore, it raised a need to specify exception limits for such actinides. In order to define credible exception limits, it was necessary to have reasonably accurate data for all actinide nuclides. Then the DGTREN/participants decided to perform calculations with different codes (MONK, MCNP, CRISTAL and SCALE) and different cross-section libraries (JEF2.2, ENDFB, etc.). The parameters of interest (such as k-infinite, critical masses) were determined. This article presents the work achieved and the questions raised, e.g. related to the effect of the radioactive decay of the isotopes on the criticality risks. It also points out the need for an evolution of the regulation of the safe transport of radioactive materials and gives a proposition of modification for the IAEA requirements related to, firstly, the list of the fissile materials, secondly, the rule to determine the quantities of actinide nuclides that can be excepted from the requirements for the packages containing fissile materials

    Full Text Available New social movements are occupying the public space. They are watching the preservation of human rights and are reinventing politics. The article is a contribution for the discussion of the state of exception and the subjectivity of the exercise of citizenship as a praxis to defend social human rights. Inspired by Luís Alberto Warat, the text treats the problem within a critical view of law based on the psychoanalytical theory of Sigmund Freud and Jacques Lacan. So, the state of anomia present in globalization is treated within a dialectical perspective: bears totalitarian violence and the chance for reinvention of rights.
