    Aggerholm, Kenneth; Moltke Martiny, Kristian

    . Through exceptional cases we can gain a deeper understanding of the ordinary. This was already a guiding thread in Merleau-Ponty’s phenomenological investigations, but this paper will take the idea further by grounding the methodology in ‘hands on’ research in elite sport (football) and pathological cases...

  2. Exceptional Reductions

    2011-01-01

    Starting from basic identities of the group E8, we perform progressive reductions, namely decompositions with respect to the maximal and symmetric embeddings of E7xSU(2) and then of E6xU(1). This procedure provides a systematic approach to the basic identities involving invariant primitive tensor structures of various irreprs. of finite-dimensional exceptional Lie groups. We derive novel identities for E7 and E6, highlighting the E8 origin of some well known ones. In order to elucidate the connections of this formalism to four-dimensional Maxwell-Einstein supergravity theories based on symmetric scalar manifolds (and related to irreducible Euclidean Jordan algebras, the unique exception being the triality-symmetric N = 2 stu model), we then derive a fundamental identity involving the unique rank-4 symmetric invariant tensor of the 0-brane charge symplectic irrepr. of U-duality groups, with potential applications in the quantization of the charge orbits of supergravity theories, as well as in the study of mult...

    2017-11-01

    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.

  6. 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.

  7. Exceptionality in vowel harmony

    Science.gov (United States)

    Szeredi, Daniel

    Vowel harmony has been of great interest in phonological research. It has been widely accepted that vowel harmony is a phonetically natural phenomenon, which means that it is a common pattern because it provides advantages to the speaker in articulation and to the listener in perception. Exceptional patterns proved to be a challenge to the phonetically grounded analysis as they, by their nature, introduce phonetically disadvantageous sequences to the surface form, that consist of harmonically different vowels. Such forms are found, for example in the Finnish stem tuoli 'chair' or in the Hungarian suffixed form hi:d-hoz 'to the bridge', both word forms containing a mix of front and back vowels. There has recently been evidence shown that there might be a phonetic level explanation for some exceptional patterns, as the possibility that some vowels participating in irregular stems (like the vowel [i] in the Hungarian stem hi:d 'bridge' above) differ in some small phonetic detail from vowels in regular stems. The main question has not been raised, though: does this phonetic detail matter for speakers? Would they use these minor differences when they have to categorize a new word as regular or irregular? A different recent trend in explaining morphophonological exceptionality by looking at the phonotactic regularities characteristic of classes of stems based on their morphological behavior. Studies have shown that speakers are aware of these regularities, and use them as cues when they have to decide what class a novel stem belongs to. These sublexical phonotactic regularities have already been shown to be present in some exceptional patterns vowel harmony, but many questions remain open: how is learning the static generalization linked to learning the allomorph selection facet of vowel harmony? How much does the effect of consonants on vowel harmony matter, when compared to the effect of vowel-to-vowel correspondences? This dissertation aims to test these two ideas

  10. Giftedness: an exceptionality examined.

    Robinson, A; Clinkenbeard, P R

    1998-01-01

    The study of giftedness has practical origins. High-level performance intrigues people. Theoretically, the study of giftedness is related to the psychology of individual differences and has focused on the constructs of intelligence, creativity, and motivation. At a practical level, the research is largely related to school and family contexts, which develop gifts and talents in children and youth. Although broadened definitions of giftedness have emerged, the most extensive body of research available for review concentrates on intellectual giftedness. The varying definitions of giftedness and the impact of social context and diversity on the development of talent pose significant challenges for the field. Finally, the study of exceptionally advanced performance provides insight into basic psychological processes and the school contexts that develop talents in children and youth.

  11. On exceptional instanton strings

    Del Zotto, Michele; Lockhart, Guglielmo

    2017-09-01

    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) , F 4 , E 6 , E 7, and E 8. These exceptional models have BPS strings which are also instantons for the corresponding gauge groups. For G simply-laced, we determine the 2d N=(0,4) worldsheet theories of such BPS instanton strings by a simple geometric engineering argument. These are given by a twisted S 2 compactification of the 4d N=2 theories of type H 2 , D 4 , E 6 , E 7 and E 8 (and their higher rank generalizations), where the 6d instanton number is mapped to the rank of the corresponding 4d SCFT. This determines their anomaly polynomials and, via topological strings, establishes an interesting relation among the corresponding T 2 × S 2 partition functions and the Hilbert series for moduli spaces of G instantons. Such relations allow to bootstrap the corresponding elliptic genera by modularity. As an example of such procedure, the elliptic genera for a single instanton string are determined. The same method also fixes the elliptic genus for case of one F 4 instanton. These results unveil a rather surprising relation with the Schur index of the corresponding 4d N=2 models.

    . This article takes Kim and Einhorn’s intervention as a starting point for a critical discussion of the history and politics of Nordic image-building. The article suggests that the reason Kim and Einhorn’s speech passed as a serious proposal was due to its meticulous mimicking of two discursive formations...... that have been central to the debates on the branding of Nordicity over the last decades: on the one hand, the discourse of “Nordic exceptionalism,” that since the 1960s has been central to the promotion of a Nordic political, socio-economic, and internationalist “third way” model, and, on the other hand......, the discourse on the “New Nordic,” that emerged out of the New Nordic Food-movement in the early 2000s, and which has given art and culture a privileged role in the international re-fashioning of the Nordic brand. Through an analysis of Kim and Einhorn’s United Nations of Norden (UNN)-performance, the article...

    2017-07-15

    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.

  18. The history of AIDS exceptionalism

    Directory of Open Access Journals (Sweden)

    Smith Julia H

    2010-12-01

    Full Text Available Abstract In the history of public health, HIV/AIDS is unique; it has widespread and long-lasting demographic, social, economic and political impacts. The global response has been unprecedented. AIDS exceptionalism - the idea that the disease requires a response above and beyond "normal" health interventions - began as a Western response to the originally terrifying and lethal nature of the virus. More recently, AIDS exceptionalism came to refer to the disease-specific global response and the resources dedicated to addressing the epidemic. There has been a backlash against this exceptionalism, with critics claiming that HIV/AIDS receives a disproportionate amount of international aid and health funding. This paper situations this debate in historical perspective. By reviewing histories of the disease, policy developments and funding patterns, it charts how the meaning of AIDS exceptionalism has shifted over three decades. It argues that while the connotation of the term has changed, the epidemic has maintained its course, and therefore some of the justifications for exceptionalism remain.

  19. Exception handling for sensor fusion

    Science.gov (United States)

    Chavez, G. T.; Murphy, Robin R.

    1993-08-01

    This paper presents a control scheme for handling sensing failures (sensor malfunctions, significant degradations in performance due to changes in the environment, and errant expectations) in sensor fusion for autonomous mobile robots. The advantages of the exception handling mechanism are that it emphasizes a fast response to sensing failures, is able to use only a partial causal model of sensing failure, and leads to a graceful degradation of sensing if the sensing failure cannot be compensated for. The exception handling mechanism consists of two modules: error classification and error recovery. The error classification module in the exception handler attempts to classify the type and source(s) of the error using a modified generate-and-test procedure. If the source of the error is isolated, the error recovery module examines its cache of recovery schemes, which either repair or replace the current sensing configuration. If the failure is due to an error in expectation or cannot be identified, the planner is alerted. Experiments using actual sensor data collected by the CSM Mobile Robotics/Machine Perception Laboratory's Denning mobile robot demonstrate the operation of the exception handling mechanism.

  20. Exceptional cognitive ability: the phenotype.

    Science.gov (United States)

    Lubinski, David

    2009-07-01

    Characterizing the outcomes related to the phenotype of exceptional cognitive abilities has been feasible in recent years due to the availability of large samples of intellectually precocious adolescents identified by modern talent searches that have been followed-up longitudinally over multiple decades. The level and pattern of cognitive abilities, even among participants within the top 1% of general intellectual ability, are related to differential developmental trajectories and important life accomplishments: The likelihood of earning a doctorate, earning exceptional compensation, publishing novels, securing patents, and earning tenure at a top university (and the academic disciplines within which tenure is most likely to occur) all vary as a function of individual differences in cognitive abilities assessed decades earlier. Individual differences that distinguish the able (top 1 in 100) from the exceptionally able (top 1 in 10,000) during early adolescence matter in life, and, given the heritability of general intelligence, they suggest that understanding the genetic and environmental origins of exceptional abilities should be a high priority for behavior genetic research, especially because the results for extreme groups could differ from the rest of the population. In addition to enhancing our understanding of the etiology of general intelligence at the extreme, such inquiry may also reveal fundamental determinants of specific abilities, like mathematical versus verbal reasoning, and the distinctive phenotypes that contrasting ability patterns are most likely to eventuate in at extraordinary levels.

  4. The Exceptional State in Africa

    DEFF Research Database (Denmark)

    Suzuki, Shogo

    2013-01-01

    China's relations with African states have undergone significant changes in recent years. China has projected its relationship with Africa as one of equality and ‘mutual help’. Such perceptions of foreign policy stem from the Five Principles of Peaceful Coexistence and the shared experience...... of imperialist domination and economic underdevelopment. Moreover, various public statements by China's elites suggest that China is expected to play a much more prominent, even exceptional role in Africa. This purportedly entails moving beyond the hegemonic West's interventionist aid or security policies......, and is also implicitly designed to highlight the West's shortcomings in promoting African economic growth or peace. Yet where does this perception of exceptionalism come from? Why does Beijing feel that it has to play a leading role in Africa's development? How can Beijing distinguish itself from the nations...

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

    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...

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 o...

    We study generalized diffeomorphisms in exceptional geometry with U-duality group E{sub n(n)} from an algebraic point of view. By extending the Lie algebra e{sub n} to an infinite-dimensional Borcherds superalgebra, involving also the extension to e{sub n+1}, the generalized Lie derivatives can be expressed in a simple way, and the expressions take the same form for any n≤7. The closure of the transformations then follows from the Jacobi identity and the grading of e{sub n+1} with respect to e{sub n}.

    We study certain four-graviton amplitudes in exceptional field theory in dimensions D≥4 up to two loops. As the formulation is manifestly invariant under the U-duality group E{sub 11−D}(ℤ), our resulting expressions can be expressed in terms of automorphic forms. In the low energy expansion, we find terms in the M-theory effective action of type R{sup 4}, ∇{sup 4}R{sup 4} and ∇{sup 6}R{sup 4} with automorphic coefficient functions in agreement with independent derivations from string theory. This provides in particular an explicit integral formula for the exact string theory ∇{sup 6}R{sup 4} threshold function. We exhibit moreover that the usual supergravity logarithmic divergences cancel out in the full exceptional field theory amplitude, within an appropriately defined dimensional regularisation scheme. We also comment on terms of higher derivative order and the role of the section constraint for possible counterterms.

  13. Light Stops at Exceptional Points

    Science.gov (United States)

    Goldzak, Tamar; Mailybaev, Alexei A.; Moiseyev, Nimrod

    2018-01-01

    Almost twenty years ago, light was slowed down to less than 10-7 of its vacuum speed in a cloud of ultracold atoms of sodium. Upon a sudden turn-off of the coupling laser, a slow light pulse can be imprinted on cold atoms such that it can be read out and converted into a photon again. In this process, the light is stopped by absorbing it and storing its shape within the atomic ensemble. Alternatively, the light can be stopped at the band edge in photonic-crystal waveguides, where the group speed vanishes. Here, we extend the phenomenon of stopped light to the new field of parity-time (P T ) symmetric systems. We show that zero group speed in P T symmetric optical waveguides can be achieved if the system is prepared at an exceptional point, where two optical modes coalesce. This effect can be tuned for optical pulses in a wide range of frequencies and bandwidths, as we demonstrate in a system of coupled waveguides with gain and loss.

  14. Reexamining the "Serbian exceptionalism" thesis

    Directory of Open Access Journals (Sweden)

    Vujačić Veljko

    2003-01-01

    Full Text Available Although former Yugoslavia constituted what was widely held to be the most "promising" communist country in terms of potentials for economic reform and political democratization, Serbia remained the only East European country in which the former communist elite managed to defeat its opponents in a series of elections and preserve important elements of institutional and ideological continuity with the old system. Moreover, its regime played a conspicuous role in Yugoslavia's violent collapse. In the specialist literature, the "Serbian exceptionalism" thesis has been elaborated in a number of forms. These are critically reviewed in the first part of the paper, classifying the paradigms according to whether they emphasize: 1 Serbian traditionalist, authoritarian, and collectivist political culture, 2 the affinity between traditional Serbian national populism, Russophile anti-Westernism, and communism, 3 the exclusivist and assimilating character of Serbian nationalism, or 4 the appeals of the contemporary Serbian political elite led by S. Milošević. In the second part of the paper an alternative explanation is presented that seeks to be both interpretively adequate and causally plausible. It rests on five basic factors: 1 historical legacy (the distinctive character of the Serbian collective historical experience and the relationship between Serbian and Yugoslav identities; 2 institutional analysis (the unintended consequences of communist federalism; 3 ideology (the revival of narratives of "Serbian victimization" by Serbian intellectuals; 4 leadership and social base (the peculiar nature of Milošević's appeals in the period of the terminal crisis of communism; and 5 the role of the Diaspora (the perceived ethnic threat among Serbs in Croatia and Bosnia. .

    2015-01-01

    This paper concerns the truly or purely cosmetic surgery conjecture. We give a survey on exceptional surgeries and cosmetic surgeries. We prove that the slope of an exceptional truly cosmetic surgery on a hyperbolic knot in $S^3$ must be $\\pm 1$ and the surgery must be toroidal but not Seifert fibred. As consequence we show that there are no exceptional truly cosmetic surgeries on certain types of hyperbolic knot in $S^3$. We also give some properties of Heegaard Floer correction terms and to...

    2016-01-01

    The cosmetic surgery conjecture is a longstanding conjecture in 3-manifold theory. We present a theorem about exceptional cosmetic surgery for homology spheres. Along the way we prove that if the surgery is not a small seifert $\\mathbb{Z}/2\\mathbb{Z}$-homology sphere or a toroidal irreducible non-Seifert surgery then there is at most one pair of exceptional truly cosmetic slope. We also prove that toroidal truly cosmetic surgeries on integer homology spheres must be integer homology spheres.

  4. 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.

    Exceptional points (EPs) are degeneracies in open wave systems where at least two energy levels and their corresponding eigenstates coalesce. We report evidence of the existence of EPs in 3D plasmonic nanostructures. The systems are composed of coupled plasmonic nanoresonators and can be judiciously and systematically driven to EPs by controlling symmetry-compatible modes via their near-field and far-field interactions. The proposed platform opens the way to the investigation of EPs for enhanced light-matter interactions and applications in communication, sensing and imaging.

  5. On the Scalar Manifold of Exceptional Supergravity

    CERN Document Server

    Cacciatori, Sergio L; Marrani, Alessio

    2012-01-01

    We construct two parametrizations of the non compact exceptional Lie group G=E7(-25), based on a fibration which has the maximal compact subgroup K=(E6 x U(1))/Z_3 as a fiber. It is well known that G plays an important role in the N=2 d=4 magic exceptional supergravity, where it describes the U-duality of the theory and where the symmetric space M=G/K gives the vector multiplets' scalar manifold. First, by making use of the exponential map, we compute a realization of G/K, that is based on the E6 invariant d-tensor, and hence exhibits the maximal possible manifest [(E6 x U(1))/Z_3]-covariance. This provides a basis for the corresponding supergravity theory, which is the analogue of the Calabi-Vesentini coordinates. Then we study the Iwasawa decomposition. Its main feature is that it is SO(8)-covariant and therefore it highlights the role of triality. Along the way we analyze the relevant chain of maximal embeddings which leads to SO(8). It is worth noticing that being based on the properties of a "mixed" Freu...

    2016-01-01

    To report a case of successful treatment for severe lipemia retinalis with extreme severe hypertriglyceridemia (sHTG). Observational case report. A 6-week-old infant with severe lipemia retinalis manifested diffuse creamy retinal vessels complicated with vulvar xanthomas. Extreme sHTG with 185-folds of the normal level was reported. Chromosome microarray and lipid gene sequencing confirmed a homozygous lipoprotein lipase gene coding mutation. Under strict adherence to a high medium-chain triglycerides formula and discontinuation of breast milk, the lipemia retinalis and vulval lesions resolved along with a stable plasma lipid level throughout the follow-up period of 6 months. Strict adherence to a low-fat diet without breast milk appears to be effective in treating infants with severe lipemia retinalis associated with exceptionally high triglycerides.

  11. Heavy Stable Isotopes: From Exceptional to Expected

    Science.gov (United States)

    Anbar, A.

    2006-12-01

    Less than a decade ago, the stable isotope geochemistry of transition metals and other "heavy" elements was a highly specialized niche confined to a few seemingly exceptional elements. This situation was transformed by the development and refinement of MC-ICP-MS techniques, particularly in the last five years. Measurable stable isotope variations turn out to be ubiquitous across the periodic table, from Li to Hg. It is now safe to assume that the isotopic composition of any element with two or more stable isotopes is measurably variable. What was once exceptional is now expected. Among the first of these new systems to be explored were Fe and Mo isotopes. A number of lessons emerging from this work can be applied to the development of other isotope systems. Most important is that initial expectations are often wrong. For example, based on their environmental chemistries it was expected that redox reactions should produce some of the largest isotope effects for both elements. In the case of Fe, theoretical and experimental studies converge to convincingly indicate that a fractionation of ~ 1.5 ‰/amu occurs between Fe(III) and Fe(II) aquo complexes at equilibrium (e.g., Welch et al., 2003; Anbar et al., 2005). Consistent with these findings, most natural variations of are < 1.5 ‰/amu (e.g., Johnson et al., 2004). This redox-related fractionation is at the heart of emerging interpretations of variations in the isotopic composition of Fe and their application to understanding ancient ocean redox (e.g., Dauphas et al., 2004; Rouxel et al., 2005). In contrast, Mo isotope variations turn out to be controlled only indirectly by redox conditions. Instead, one of the most important Mo isotope effects in the environment appears to be a fractionation of ~ 1 ‰/amu during adsorption of Mo to Mn-oxides (Barling et al., 2001; Siebert et al., 2003). This fractionation has been reproduced in the laboratory (Barling and Anbar, 2004) and appears to be an equilibrium isotope

    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.

    In this article we provide a detailed description of a technique to obtain a simple parameterization for different exceptional Lie groups, such as G{sub 2}, F{sub 4} and E{sub 6}, based on their fibration structure. For the compact case, we construct a realization which is a generalization of the Euler angles for SU(2), while for the non compact version of G{sub 2(2)}/SO(4) we compute the Iwasawa decomposition. This allows us to obtain not only an explicit expression for the Haar measure on the group manifold, but also for the cosets G{sub 2}/SO(4), G{sub 2}/SU(3), F{sub 4}/Spin(9), E{sub 6}/F{sub 4} and G{sub 2(2)}/SO(4) that we used to find the concrete realization of the general element of the group. Moreover, as a by-product, in the simplest case of G{sub 2}/SO(4), we have been able to compute an Einstein metric and the vielbein. The relevance of these results in physics is discussed.

    A number of leading theories of aging, namely The Antagonistic Pleiotropy Theory (Williams, 1957), The Disposable Soma Theory (Kirkwood, 1977) and most recently The Reproductive-Cell Cycle Theory (Bowen and Atwood, 2004, 2010) suggest a tradeoff between longevity and reproduction. While there has been an abundance of data linking longevity with reduced fertility in lower life forms, human data have been conflicting. We assessed this tradeoff in a cohort of genetically and socially homogenous Ashkenazi Jewish centenarians (average age ~100 years). As compared with an Ashkenazi cohort without exceptional longevity, our centenarians had fewer children (2.01 vs 2.53, p<0.0001), were older at first childbirth (28.0 vs 25.6, p<0.0001), and at last childbirth (32.4 vs 30.3, p<0.0001). The smaller number of children was observed for male and female centenarians alike. The lower number of children in both genders together with the pattern of delayed reproductive maturity is suggestive of constitutional factors that might enhance human life span at the expense of reduced reproductive ability.

    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&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

The study included 175 teachers, five primary and five secondary schools. The age of respondents (teachers ranges from 20 to 65, with average age being 44,33 years. The used  instrument has assessed violence against teachers and has consisted of  data about the characteristics of respondents, frequency and type of violence experienced from students.The results suggest that violence against teachers in primary and secondary schools in Zagreb taken into sample is very much present. Since 74,3% teachers has experienced violence from their students during the year, that kind of behavior is more of a rule than an exception. Students in primary and secondary schools show violent behavior against their teachers at an equal level. Male teachers, as opposed to female teachers, are more frequently victims of violent behavior (posting inappropriate content online from their students. Also, there is a statistically significant correlation (negative between age (years of service in school and frequency of experienced violence from students.

  20. "No admittance except on business" 

    Directory of Open Access Journals (Sweden)

    Mathilde Bourrier

     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

    DEFF Research Database (Denmark)

    An operation on an element container is said to provide a strong guarantee of exception safety if, in case an exception is thrown, the operation leaves the container in the state in which it was before the operation. In this paper, we explore how to adjust operations on C++ standard......-library containers to provide the strong guarantee of exception safety, instead of the default guarantee, without violating the stringent performance requirements specified in the C++ standard. In particular, we show that every strongly exception-safe operation on dynamic arrays and ordered dictionaries is only...

  15. Space Science IS Accessible to Students with Exceptional Needs: Results from Exceptional Needs Workshops

    Science.gov (United States)

    Runyon, C. J.; Merritt, M.; Guimond, K.

    2003-12-01

    The majority of students with disabilities in the US are required to achieve the same academic levels as their non-impaired peers. Unfortunately, there are few specialized materials to help these exceptional students. To assist students in meeting their goals, SERCH, a NASA Office of Space Science Broker/Facilitator, has been working with NASA education product developers and educators from informal and formal settings to identify what kinds of materials they need and what mediums will work best. As a result of both direct classrooms observations and hands-on workshops we have begun generating adaptive lessons plans that meet the national standards for Science, Technology, Engineering and Mathematics. During the workshops, participants simulate various disabilities (e.g., hearing, vision, orthopedic impairments, learning difficulties) while working through Space Science activities and discuss necessary adaptations/modifications in real-time. For example, we modified the Solar System Distance activity first designed by ASU to include the use of larger beads or pom-poms instead of the suggested small plastic beads. This simple adaptation permits students with orthopedic impairments to more readily take part in the lesson and to actively "observe" the distance between the planets. Examples of this activity and more will be illustrated. In addition to making modifications and suggestions for adaptations, workshop participants shared many simple recommendations that can help ALL learners participate more readily in classroom activities and discussions. Among these are: (1) Use simple, sans-serif fonts and high contrast presentation media (e.g., white text on black is most effective); (2) Repetition and use of multiple presentation modes is very helpful. (3) Actively involve the learner, and (4) Keep things simple to begin with, then work toward the more complex - think of the audience, the ultimate user.

    Quality improvement programs that allow physicians to document medical reasons for deviating from guidelines preserve clinicians' judgment while enabling them to strive for high performance. However, physician misconceptions or gaming potentially limit programs. To implement computerized decision support with mechanisms to document medical exceptions to quality measures and to perform peer review of exceptions and provide feedback when appropriate. Observational study. Large internal medicine practice. Patients eligible for 1 or more quality measures. A peer-review panel judged medical exceptions to 16 chronic disease and prevention quality measures as appropriate, inappropriate, or of uncertain appropriateness. Medical records were reviewed after feedback was given to determine whether care changed. Physicians recorded 650 standardized medical exceptions during 7 months. The reporting tool was used without any medical reason 36 times (5.5%). Of the remaining 614 exceptions, 93.6% were medically appropriate, 3.1% were inappropriate, and 3.3% were of uncertain appropriateness. Frequencies of inappropriate exceptions were 7 (6.9%) for coronary heart disease, 0 (0%) for heart failure, 10 (10.8%) for diabetes, and 2 (0.6%) for preventive services. After physicians received direct feedback about inappropriate exceptions, 8 of 19 (42%) changed management. The peer-review process took less than 5 minutes per case, but for each change in clinical care, 65 reviews were required. The findings could differ at other sites or if financial incentives were in place. Physician-recorded medical exceptions were correct most of the time. Peer review of medical exceptions can identify myths and misconceptions, but the process needs to be more efficient to be sustainable. Agency for Healthcare Research and Quality.

    Shi, Chengzhi; Dubois, Marc; Chen, Yun; Cheng, Lei; Ramezani, Hamidreza; Wang, Yuan; Zhang, Xiang

    2016-01-01

    Parity-time (PT) symmetric systems experience phase transition between PT exact and broken phases at exceptional point. These PT phase transitions contribute significantly to the design of single mode lasers, coherent perfect absorbers, isolators, and diodes. However, such exceptional points are extremely difficult to access in practice because of the dispersive behaviour of most loss and gain materials required in PT symmetric systems. Here we introduce a method to systematically tame these exceptional points and control PT phases. Our experimental demonstration hinges on an active acoustic element that realizes a complex-valued potential and simultaneously controls the multiple interference in the structure. The manipulation of exceptional points offers new routes to broaden applications for PT symmetric physics in acoustics, optics, microwaves and electronics, which are essential for sensing, communication and imaging.

  4. Exceptional epidemics: AIDS still deserves a global response

    Directory of Open Access Journals (Sweden)

    Smith Julia

    2009-11-01

    Full Text Available Abstract There has been a renewed debate over whether AIDS deserves an exceptional response. We argue that as AIDS is having differentiated impacts depending on the scale of the epidemic, and population groups impacted, and so responses must be tailored accordingly. AIDS is exceptional, but not everywhere. Exceptionalism developed as a Western reaction to a once poorly understood epidemic, but remains relevant in the current multi-dimensional global response. The attack on AIDS exceptionalism has arisen because of the amount of funding targeted to the disease and the belief that AIDS activists prioritize it above other health issues. The strongest detractors of exceptionalism claim that the AIDS response has undermined health systems in developing countries. We agree that in countries with low prevalence, AIDS should be normalised and treated as a public health issue--but responses must forcefully address human rights and tackle the stigma and discrimination faced by marginalized groups. Similarly, AIDS should be normalized in countries with mid-level prevalence, except when life-long treatment is dependent on outside resources--as is the case with most African countries--because treatment dependency creates unique sustainability challenges. AIDS always requires an exceptional response in countries with high prevalence (over 10 percent. In these settings there is substantial morbidity, filling hospitals and increasing care burdens; and increased mortality, which most visibly reduces life expectancy. The idea that exceptionalism is somehow wrong is an oversimplification. The AIDS response can not be mounted in isolation; it is part of the development agenda. It must be based on human rights principles, and it must aim to improve health and well-being of societies as a whole.

    Malek, E.

    We show how to construct half-maximal consistent truncations of 10- and 11-dimensional supergravity to seven dimensions using exceptional field theory. This procedure gives rise to a seven-dimensional half-maximal gauged supergravity coupled to n vector multiplets, with n ≠ 3 in general. We also show how these techniques can be used to reduce exceptional field theory to heterotic double field theory.

There is a growing literature of scholarly opinion about twice exceptionality; however, there are few well-designed empirical investigations of gifted students with anxiety, depression, bipolar di...

  7. 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.

  8. Exceptional giftedness in early adolescence and intrafamilial divergent thinking.

    Runco, M A; Albert, R S

    1986-08-01

    Two groups of boys and their parents (N=54) were given five divergent thinking tests as one part of a longitudinal investigation on exceptional giftedness in early adolescence. One groups of adolescents was selected because their IQs were above 150, and the other group, was selected because of their outstanding math-science abilities. Canonical and bivariate analyses indicated that there was a strong correlation between the adolescents' divergent thinking test scores and their parents' divergent thinking test scores (Rc=.55). Additionally, there was some indication that these correlations differed in the two exceptionally gifted groups, with the high-IQ group having divergent thinking test scores related to those of both parents, and the math-science group having divergent thinking test scores related only to those of their mothers. These findings are very consistent with earlier investigations on exceptionally gifted adolescents.

  9. Exceptional points enhance sensing in an optical microcavity

    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.

  10. Spawning rings of exceptional points out of Dirac cones.

    The Dirac cone underlies many unique electronic properties of graphene and topological insulators, and its band structure--two conical bands touching at a single point--has also been realized for photons in waveguide arrays, atoms in optical lattices, and through accidental degeneracy. Deformation of the Dirac cone often reveals intriguing properties; an example is the quantum Hall effect, where a constant magnetic field breaks the Dirac cone into isolated Landau levels. A seemingly unrelated phenomenon is the exceptional point, also known as the parity-time symmetry breaking point, where two resonances coincide in both their positions and widths. Exceptional points lead to counter-intuitive phenomena such as loss-induced transparency, unidirectional transmission or reflection, and lasers with reversed pump dependence or single-mode operation. Dirac cones and exceptional points are connected: it was theoretically suggested that certain non-Hermitian perturbations can deform a Dirac cone and spawn a ring of exceptional points. Here we experimentally demonstrate such an 'exceptional ring' in a photonic crystal slab. Angle-resolved reflection measurements of the photonic crystal slab reveal that the peaks of reflectivity follow the conical band structure of a Dirac cone resulting from accidental degeneracy, whereas the complex eigenvalues of the system are deformed into a two-dimensional flat band enclosed by an exceptional ring. This deformation arises from the dissimilar radiation rates of dipole and quadrupole resonances, which play a role analogous to the loss and gain in parity-time symmetric systems. Our results indicate that the radiation existing in any open system can fundamentally alter its physical properties in ways previously expected only in the presence of material loss and gain.

    2015-07-01

    Full Text Available We provide the mathematical foundation for the $X_m$-Jacobi spectral theory. Namely, we present a self-adjoint operator associated to the differential expression with the exceptional $X_m$-Jacobi orthogonal polynomials as eigenfunctions. This proves that those polynomials are indeed eigenfunctions of the self-adjoint operator (rather than just formal eigenfunctions. Further, we prove the completeness of the exceptional $X_m$-Jacobi orthogonal polynomials (of degrees $m, m+1, m+2, \\dots$ in the Lebesgue-Hilbert space with the appropriate weight. In particular, the self-adjoint operator has no other spectrum.

    The spectra of, e.g. open quantum systems are typically given as the superposition of resonances with a Lorentzian line shape, where each resonance is related to a simple pole in the complex energy domain. However, at exceptional points two or more resonances are degenerate and the resulting non-Lorentzian line shapes are related to higher order poles in the complex energy domain. In the Fourier-transform time domain an $n$-th order exceptional point is characterised by a non-exponentially de...

    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.

  5. ADHD and giftedness: a neurocognitive consideration of twice exceptionality.

    Science.gov (United States)

    Budding, Deborah; Chidekel, Dana

    2012-01-01

    Current models of cognition and behavioral diagnosis emphasize categorical classification over continuous considerations of function and promote the "differential diagnosis" of various conditions according to observational criteria. However, an overemphasis on a purely behavioral, categorical approach to understanding human function fails to address the comorbidity of different disorders and does not include a consideration of overlapping levels of function, from "pathological" through "normal," to "gifted" or exceptional. The frequent co-occurrence of "gifted" and "pathological" function is thus difficult to understand from a corticocentric and purely behavioral and observational point of view. This article reviews "giftedness" in relation to the diagnosis of attention-deficit hyperactivity disorder, coexistence of which is termed "twice exceptional." It additionally considers problems in assessing these functions using current neuropsychological tests and methodologies that are presumably based upon a corticocentric model of cognition.

  6. 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.

    Non-Hermitian degeneracies, also known as exceptional points, have recently emerged as a new way to engineer the response of open physical systems, that is, those that interact with the environment. They correspond to points in parameter space at which the eigenvalues of the underlying system and the corresponding eigenvectors simultaneously coalesce. In optics, the abrupt nature of the phase transitions that are encountered around exceptional points has been shown to lead to many intriguing phenomena, such as loss-induced transparency, unidirectional invisibility, band merging, topological chirality and laser mode selectivity. Recently, it has been shown that the bifurcation properties of second-order non-Hermitian degeneracies can provide a means of enhancing the sensitivity (frequency shifts) of resonant optical structures to external perturbations. Of particular interest is the use of even higher-order exceptional points (greater than second order), which in principle could further amplify the effect of perturbations, leading to even greater sensitivity. Although a growing number of theoretical studies have been devoted to such higher-order degeneracies, their experimental demonstration in the optical domain has so far remained elusive. Here we report the observation of higher-order exceptional points in a coupled cavity arrangement—specifically, a ternary, parity-time-symmetric photonic laser molecule—with a carefully tailored gain-loss distribution. We study the system in the spectral domain and find that the frequency response associated with this system follows a cube-root dependence on induced perturbations in the refractive index. Our work paves the way for utilizing non-Hermitian degeneracies in fields including photonics, optomechanics, microwaves and atomic physics.

  14. Particle actions and brane tensions from double and exceptional geometry

    Science.gov (United States)

    Blair, Chris D. A.

    2017-10-01

    Massless particles in n + 1 dimensions lead to massive particles in n dimensions on Kaluza-Klein reduction. In string theory, wrapped branes lead to multiplets of massive particles in n dimensions, in representations of a duality group G. By encoding the masses of these particles in auxiliary worldline scalars, also transforming under G, we write an action which resembles that for a massless particle on an extended spacetime. We associate this extended spacetime with that appearing in double field theory and exceptional field theory, and formulate a version of the action which is invariant under the generalised diffeomorphism symmetry of these theories. This provides a higher-dimensional perspective on the origin of mass and tension in string theory and M-theory. Finally, we consider the reduction of exceptional field theory on a twisted torus, which is known to give the massive IIA theory of Romans. In this case, our particle action leads naturally to the action for a D0 brane in massive IIA. Here an extra vector field is present on the worldline, whose origin in exceptional field theory is a vector field introduced to ensure invariance under generalised diffeomorphisms.

    We present an exceptional association of splenogonadal fusion, Moebius syndrome, and intestinal intussusception. At the age of 1 year, the patient presented with vomiting, bloody stools, and abdominal distension. He underwent a laparotomy that revealed an ileo-ileal intussusception. Three days later, he underwent a new surgery for the reduction of a suspected inguinal hernia. A dark-red tubular structure consisting of splenic tissue was seen passing down through the processus vaginalis and attaching onto the left testicle. Owing to the rarity of the splenogonadal fusion, each case should be reported for a better knowledge of its etiopathogenesis, clinical characteristic and associations.

    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.

  17. Scandinavian exceptionalism in anti-doping within sport

    Why are Scandinavian countries so committed to the cause of antidoping? In this paper, we propose that the Scandinavian mentality, formed by paternalistic welfare models, is a useful framework for understanding anti-doping. We focus on anti-doping policy and work in Norway and Denmark. We start......: the Norwegian self-image and its impact on politics, and Danish amateurism and corrupt idealism. We conclude that Nordic antidoping is pursued with rigour and determination, and suggest this is rooted in the Nordic countries’ exceptional social-welfare ideology and strong paternalism....

    Various ways of controlling the extent of the ring of exceptional points in photonic crystal slabs are investigated. The extent of the ring in photonic crystal slabs is found to vary with the thickness of the slab. This enables recovery of Dirac cones in open, non-Hermitian systems......, such as a photonic crystal slab. In this case, all three bands exhibit a bound state in the continuum in close proximity of the Γ point. These results may lead to new designs of small photonic-crystal-based lasers exhibiting high-quality factors....

  20. Break-glass handling exceptional situations in access control

    2014-01-01

    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.

    Exceptional points (EPs) are degeneracies in open wave systems where at least two energy levels and their corresponding eigenstates coalesce. We report evidence of the existence of EPs in three-dimensional (3D) plasmonic nanostructures. The systems are composed of coupled plasmonic nanoresonators and can be judiciously and systematically driven to EPs by controlling symmetry-compatible modes via their near-field and far-field interactions. The proposed platform opens the way to the investigation of EPs for enhanced light-matter interactions and applications in communication, sensing, and imaging.

  2. Nothing in biology makes sense except in light of theology?

    2013-12-01

    This essay analyzes Theodosius Dobzhansky's famous article, "Nothing in Biology Makes Sense Except in the Light of Evolution," in which he presents some of his best arguments for evolution. I contend that all of Dobzhansky's arguments hinge upon sectarian claims about God's nature, actions, purposes, or duties. Moreover, Dobzhansky's theology manifests several tensions, both in the epistemic justification of his theological claims and in their collective coherence. I note that other prominent biologists--such as Mayr, Dawkins, Eldredge, Ayala, de Beer, Futuyma, and Gould--also use theology-laden arguments. I recommend increased analysis of the justification, complexity, and coherence of this theology. Copyright © 2013 Elsevier Ltd. All rights reserved.

  3. Bringing Anomie Back In: Exceptional Events and Excess Suicide

    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.

    In an effort to further develop shape memory alloys (SMAs) for functional applications, much focus has been given in recent years to design and create innovative forms of SMAs, such as functionally graded SMAs, architecture SMAs, and SMA-based metallic composites. This paper reports on the progress in creating NiTi-based composites of exceptional properties stimulated by the recent discovery of the principle of lattice strain matching between the SMA matrix and superelastic nanoinclusions embedded in the matrix. Based on this principle, different SMA-metal composites have been designed to achieve extraordinary shape memory performances, such as complete pseudoelastic behavior at as low as 77 K and stress plateau as high as 1600 MPa, and exceptional mechanical properties, such as tensile strength as high as 2000 MPa and Young's modulus as low as 28 GPa. Details are given for a NiTi-W micro-fiber composite prepared by melt infiltration, hot pressing, forging, and cold rolling. The composite contained 63% in volume of W micro-fibers of 0.6 μm thickness. In situ synchrotron X-ray diffraction revealed that the NiTi matrix underwent martensite transformation during tensile deformation while the W micro-fiber deformed elastically with a maximum strain of 0.83% in the loading direction, implying a W fiber stress of 3280 MPa. The composite showed a maximum high tensile strength of 2300 MPa.

    Full Text Available Mirizzi syndrome is defined as an obstruction of the hepatic duct by an impacted biliary stone in the Hartmann's pouch of the gallbladder or in the cystic duct (Mirizzi type I. The gallstone may erode the bile duct causing a cholecystobiliary fistula (Mirizzi type II. This very rare complication of long standing cholelithiasis is mainly reported in adults. We report an exceptional case of a type I Mirizzi syndrome in a 3-year-old boy, incidentally discovered during a computed tomography study. Ultrasonography and cholangioresonance confirmed the diagnosis. At laparoscopy, partial fusion between the Hartmann's pouch and the hepatic duct was found. Despite difficult dissection, a total laparoscopic cholecystectomy was performed. Preoperative diagnosis of this syndrome is difficult owing to unspecific clinical presentation and low sensitivity of the standard radiological studies. To detect and correctly identify the type of Mirizzi syndrome during surgery is very important in order to avoid serious complications and to perform the most adequate surgical treatment. Open subtotal cholecystectomy is the recommended procedure in Mirizzi type I, laparoscopic total cholecystectomy being possible in some cases. Although this entity is exceptional in children, it must be known and considered by the Pediatric Surgeon because its development is possible.

    2015-01-01

    Studies published in the late 1990s and early 2000s identified the presence of exceptionally long methyl tert-butyl ether (MTBE) plumes (more than 600 m or 2000 feet) in groundwater and have been cited in technical literature as characteristic of MTBE plumes. However, the scientific literature is incomplete in regard to the subsequent behavior and fate of these MTBE plumes over the past decade. To address this gap, this issue paper compiles recent groundwater monitoring records for nine exceptional plumes that were identified in prior studies. These nine sites exhibited maximum historical MTBE groundwater plume lengths ranging from 820 m (2700 feet) to 3200 m (10,500 feet) in length, exceeding the lengths of 99% of MTBE plumes, as characterized in multiple surveys at underground storage tank sites across the United States. Groundwater monitoring data compiled in our review demonstrate that these MTBE plumes have decreased in length over the past decade, with five of the nine plumes exhibiting decreases of 75% or more compared to their historical maximum lengths. MTBE concentrations within these plumes have decreased by 93% to 100%, with two of the nine sites showing significant decreases (98% and 99%) such that the regulatory authority has subsequently designated the site as requiring no further action. © 2015 The Authors.

  8. Confrontation Between Judicial Activism and State of Exception

    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.

  9. 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.

    Although the perception of music is generally poor in cochlear implant users, there are a few excellent performers. The aim of this study was the assessment of different aspects of music perception in one exceptional cochlear implant user. The assessments included pitch direction discrimination, melody and timbre recognition, relative and absolute pitch judgment, and consonance rating of musical notes presented through the sound processor(s). An adult cochlear implant user with musical background who lost her hearing postlingually, and five normally-hearing listeners with musical training participated in the study. The CI user discriminated pitch direction for sounds differing by one semitone and recognized melody with nearly 100% accuracy. Her results in timbre recognition were better than average published data for cochlear implant users. Her consonance rating, and relative and absolute pitch perception were comparable to normally-hearing listeners with musical training. The results in this study showed that excellent performance is possible on musical perception tasks including pitch perception using present day cochlear implant technologies. Factors that may explain this user's exceptional performance are short duration of deafness, pre- and post-deafness musical training, and perfect pitch abilities before the onset of deafness.

    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.

    To investigate the clinical effect of Meek technique skin graft in treating exceptionally large area burns. The clinical data were retrospectively analysed from 10 cases of exceptionally large area burns treated with Meek technique skin graft from April 2009 to February 2010 (Meek group), and were compared with those from 10 cases of exceptionally large area burns treated with the particle skin with large sheet of skin allograft transplantation from January 2002 to December 2006 (particle skin group). In Meek group, there were 8 males and 2 females with an average age of 34.5 years (range, 5-55 years), including 6 cases of flame burns, 2 cases of hot liquid burns, 1 case of electrical burn, and 1 case of high-temperature dust burn. The burn area was 82.6% +/- 3.1% of total body surface area (TBSA). The most were deep II degree to III degree burns. The time from burn to hospitalization was (3.5 +/- 1.3) hours. In particle skin group, there were 8 males and 2 females with an average age of 36.8 years (range, 18-62 years), including 5 cases of flame burns, 2 cases of hot liquid burns, and 3 cases of gunpowder explosion injury. The burn area was 84.1% +/- 7.4% of TBSA. The most were deep II degree to III degree burns. The time from burn to hospitalization was (4.9 +/- 2.2) hours. There was no significant difference in general data between 2 groups (P > 0.05). The skin graft survival rate, the time of skin fusion, the systemic wound healing time, and the treatment cost of 1% of burn area were 91.23% +/- 5.61%, (11.14 +/- 2.12) days, (38.89 +/- 10.36) days, and (5113.28 +/- 552.44) yuan in Meek group, respectively; and were 78.65% +/- 12.29%, (18.37 +/- 4.63) days, (48.73 +/- 16.92) days, and (7386.36 +/- 867.64) yuan in particle skin group; showing significant differences between 2 groups (P burns with the advantages of high survival rate of skin graft, short time of skin fusion, and low treatment cost of 1% of burn area.

  13. Mortality Trajectories at Exceptionally High Ages: A Study of Supercentenarians.

    The growing number of persons surviving to age 100 years and beyond raises questions about the shape of mortality trajectories at exceptionally high ages, and this problem may become significant for actuaries in the near future. However, such studies are scarce because of the difficulties in obtaining reliable age estimates at exceptionally high ages. The current view about mortality beyond age 110 years suggests that death rates do not grow with age and are virtually flat. The same assumption is made in the new actuarial VBT tables. In this paper, we test the hypothesis that the mortality of supercentenarians (persons living 110+ years) is constant and does not grow with age, and we analyze mortality trajectories at these exceptionally high ages. Death records of supercentenarians were taken from the International Database on Longevity (IDL). All ages of supercentenarians in the database were subjected to careful validation. We used IDL records for persons belonging to extinct birth cohorts (born before 1895) since the last deaths in IDL were observed in 2007. We also compared our results based on IDL data with a more contemporary database maintained by the Gerontology Research Group (GRG). First we attempted to replicate findings by Gampe (2010), who analyzed IDL data and came to the conclusion that "human mortality after age 110 is flat." We split IDL data into two groups: cohorts born before 1885 and cohorts born in 1885 and later. Hazard rate estimates were conducted using the standard procedure available in Stata software. We found that mortality in both groups grows with age, although in older cohorts, growth was slower compared with more recent cohorts and not statistically significant. Mortality analysis of more numerous 1884-1894 birth cohort with the Akaike goodness-of-fit criterion showed better fit for the Gompertz model than for the exponential model (flat mortality). Mortality analyses with GRG data produced similar results. The remaining life

    Using data obtained from different physical techniques (i.e., neutron diffraction, NMR and UV spectroscopy), we present evidence which explains some of the conflicting and inexplicable data found in the literature regarding -tocopherol s (aToc s) behavior in dimyristoyl phosphatidylcholine (di-14:0PC) bilayers. Without exception, the data point to aToc s active chromanol moiety residing deep in the hydrophobic core of di-14:0PC bilayers, a location that is in stark contrast to aToc s location in other PC bilayers. Our result is a clear example of the importance of lipid species diversity in biological membranes and importantly, it suggests that measurements of aToc s oxidation kinetics, and its associated byproducts observed in di-14:0PC bilayers, should be reexamined, this time taking into account its noncanonical location in this bilayer.

    The remarkable diversity of the morphologies of viruses found in terrestrial hydrothermal environments with temperatures >80 degrees C is unprecedented for aquatic ecosystems. The best-studied viruses from these habitats have been assigned to novel viral families: Fuselloviridae, Lipothrixviridae...... no significant matches to sequences in public databases. This suggests that these hyperthermophilic viruses have exceptional biochemical solutions for biological functions.

    Ke, Shaolin; Qin, Chengzhi; Long, Hua; Wang, Kai; Lu, Peixiang

    2016-01-01

    We investigate the exceptional points (EPs) in a non-Hermitian system composed of a pair of graphene sheets with different losses. There are two surface plasmon polaritons (SPP) modes in the graphene waveguide. By varying the distance between two graphene sheets and chemical potential of graphene, the EPs appear as the eigenvalues, that is, the wave vectors of the two modes coalesce. The cross conversion of eigenmodes and variation of geometric phase can be observed by encircling the EP in the parametric space formed by the geometric parameters and chemical potential of graphene. At the same time, a certain input SPP mode may lead to completely different output. The study paves a way to the development of nanoscale sensitive optical switches and sensors.

    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.

    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.

    We investigate the optical exceptional points (EPs) in the graphene incorporated multilayer metamaterial manifesting Fano resonance. The system is non-Hermitian and possesses EPs where both the eigenvalues and eigenvectors of the Hamiltonian coalesce. In the aid of Fano resonance, the reflection may reach minimum approaching to zero, resulting in the degeneration of both eigenvalues and eigenvectors and thus the emergence of EPs. The transmission and reflection of light through the metamaterial change sharply by varying slightly the incident wavelength and chemical potential of graphene in the parameter space when encircling the EPs. In addition, the unidirectional invisibility can be achieved at EPs. The study paves a way to precisely controlling the transmission and reflection through metamaterials and may find applications in optoelectronic switches, modulators, absorbers, and optical sensors.

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

    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.

    Full Text Available Alteration of single genes involved in nutrient and lipoprotein metabolism increases longevity in several animal models. Because exceptional longevity in humans is familial, it is likely that polymorphisms in genes favorably influence certain phenotypes and increase the likelihood of exceptional longevity. A group of Ashkenazi Jewish centenarians (n = 213, their offspring (n = 216, and an age-matched Ashkenazi control group (n = 258 were genotyped for 66 polymorphisms in 36 candidate genes related to cardiovascular disease (CVD. These genes were tested for association with serum lipoprotein levels and particle sizes, apolipoprotein A1, B, and C-3 levels and with outcomes of hypertension, insulin resistance, and mortality. The prevalence of homozygosity for the -641C allele in the APOC3 promoter (rs2542052 was higher in centenarians (25% and their offspring (20% than in controls (10% (p = 0.0001 and p = 0.001, respectively. This genotype was associated with significantly lower serum levels of APOC3 and a favorable pattern of lipoprotein levels and sizes. We found a lower prevalence of hypertension and greater insulin sensitivity in the -641C homozygotes, suggesting a protective effect against CVD and the metabolic syndrome. Finally, in a prospectively studied cohort, a significant survival advantage was demonstrated in those with the favorable -641C homozygote (p < 0.0001. Homozygosity for the APOC3 -641C allele is associated with a favorable lipoprotein profile, cardiovascular health, insulin sensitivity, and longevity. Because modulation of lipoproteins is also seen in genetically altered longevity models, it may be a common pathway influencing lifespan from nematodes to humans.

  6. Assessing the Exceptionality of Coloured Motifs in Networks

    2009-01-01

    Full Text Available Various methods have been recently employed to characterise the structure of biological networks. In particular, the concept of network motif and the related one of coloured motif have proven useful to model the notion of a functional/evolutionary building block. However, algorithms that enumerate all the motifs of a network may produce a very large output, and methods to decide which motifs should be selected for downstream analysis are needed. A widely used method is to assess if the motif is exceptional, that is, over- or under-represented with respect to a null hypothesis. Much effort has been put in the last thirty years to derive -values for the frequencies of topological motifs, that is, fixed subgraphs. They rely either on (compound Poisson and Gaussian approximations for the motif count distribution in Erdös-Rényi random graphs or on simulations in other models. We focus on a different definition of graph motifs that corresponds to coloured motifs. A coloured motif is a connected subgraph with fixed vertex colours but unspecified topology. Our work is the first analytical attempt to assess the exceptionality of coloured motifs in networks without any simulation. We first establish analytical formulae for the mean and the variance of the count of a coloured motif in an Erdös-Rényi random graph model. Using simulations under this model, we further show that a Pólya-Aeppli distribution better approximates the distribution of the motif count compared to Gaussian or Poisson distributions. The Pólya-Aeppli distribution, and more generally the compound Poisson distributions, are indeed well designed to model counts of clumping events. Altogether, these results enable to derive a -value for a coloured motif, without spending time on simulations.

  7. Phase diagrams of exceptional and supersymmetric lattice gauge theories

    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.

    Changes to the dynamics of the Greenland ice sheet can be forced by various mechanisms including surface-melt-induced ice acceleration and oceanic forcing of marine-terminating glaciers. We use observations of ice motion to examine the surface melt-induced dynamic response of a land-terminating outlet glacier in southwest Greenland to the exceptional melting observed in 2012. During summer, meltwater generated on the Greenland ice sheet surface accesses the ice sheet bed, lubricating basal motion and resulting in periods of faster ice flow. However, the net impact of varying meltwater volumes upon seasonal and annual ice flow, and thus sea level rise, remains unclear. We show that two extreme melt events (98.6% of the Greenland ice sheet surface experienced melting on July 12, the most significant melt event since 1889, and 79.2% on July 29) and summer ice sheet runoff ~3.9 σ above the 1958-2011 mean resulted in enhanced summer ice motion relative to the average melt year of 2009. However, despite record summer melting, subsequent reduced winter ice motion resulted in 6% less net annual ice motion in 2012 than in 2009. Our findings suggest that surface melt-induced acceleration of land-terminating regions of the ice sheet will remain insignificant even under extreme melting scenarios.

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

    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.

  12. Psychological factors in exceptional, extreme and torturous environments.

    Leach, John

    2016-01-01

    Our cognitive system has adapted to support goal-directed behaviour within a normal environment. An abnormal environment is one to which we are not optimally adapted but can accommodate through the development of coping strategies. These abnormal environments can be 'exceptional', e.g., polar base, space station, submarine, prison, intensive care unit, isolation ward etc.; 'extreme', marked by more intense environmental stimuli and a real or perceived lack of control over the situation, e.g., surviving at sea in a life-raft, harsh prison camp etc.; or 'tortuous', when specific environmental stimuli are used deliberately against a person in an attempt to undermine his will or resistance. The main factors in an abnormal environment are: psychological (isolation, sensory deprivation, sensory overload, sleep deprivation, temporal disorientation); psychophysiological (thermal, stress positions), and psychosocial (cultural humiliation, sexual degradation). Each single factor may not be considered tortuous, however, if deliberately structured into a systemic cluster may constitute torture under legal definition. The individual experience of extremis can be pathogenic or salutogenic and attempts are being made to capitalise on these positive experiences whilst ameliorating the more negative aspects of living in an abnormal environment.

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

    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.

  14. Alternative protein-protein interfaces are frequent exceptions.

    Directory of Open Access Journals (Sweden)

    Tobias Hamp

    Full Text Available The intricate molecular details of protein-protein interactions (PPIs are crucial for function. Therefore, measuring the same interacting protein pair again, we expect the same result. This work measured the similarity in the molecular details of interaction for the same and for homologous protein pairs between different experiments. All scores analyzed suggested that different experiments often find exceptions in the interfaces of similar PPIs: up to 22% of all comparisons revealed some differences even for sequence-identical pairs of proteins. The corresponding number for pairs of close homologs reached 68%. Conversely, the interfaces differed entirely for 12-29% of all comparisons. All these estimates were calculated after redundancy reduction. The magnitude of interface differences ranged from subtle to the extreme, as illustrated by a few examples. An extreme case was a change of the interacting domains between two observations of the same biological interaction. One reason for different interfaces was the number of copies of an interaction in the same complex: the probability of observing alternative binding modes increases with the number of copies. Even after removing the special cases with alternative hetero-interfaces to the same homomer, a substantial variability remained. Our results strongly support the surprising notion that there are many alternative solutions to make the intricate molecular details of PPIs crucial for function.

  15. Exceptional molecular organization of canthaxanthin in lipid membranes.

    2012-01-01

    Canthaxanthin (β,β-carotene 4,4' dione) used widely as a drug or as a food and cosmetic colorant may have some undesirable effects on human health, caused mainly by the formation of crystals in the macula lutea membranes of the retina of an eye. Experiments show the exceptional molecular organization of canthaxanthin and a strong effect of this pigment on the physical properties of lipid membranes. The most striking difference between canthaxanthin and other macular pigments is that the effects of canthaxanthin at a molecular level are observed at much lower concentration of this pigment with respect to lipid (as low as 0.05 mol%). An analysis of the molecular interactions of canthaxanthin showed molecular mechanisms such as: strong van der Waals interactions between the canthaxanthin molecule and the acyl chains of lipids, restrictions to the segmental molecular motion of lipid molecules, modifications of the surface of the lipid membranes, effect on the membrane thermotropic properties and finally interactions based on the formation of the hydrogen bonds. Such interactions can lead to a destabilization of the membrane and loss of membrane compactness. In the case of the retinal vasculature, it can lead to an increase in the permeability of the retinal capillary walls and the development of retinopathy.

    Electric double layer (EDL) capacitors are promising as next-generation energy accumulators if their capacitances and operation voltages are both high. 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.

  17. Gastric outlet obstruction: Report of an exceptional case

    2017-01-01

    Full Text Available Although gastric outlet obstruction is a common condition, etiology could not be determined in a few cases by means of clinical features, radiological, and endoscopic examination, resulting in substantial diagnostic dilemma. A case is being described where a 30-year-old male presented with anorexia, dyspepsia, vomiting, low-grade fever, and weight loss for 2 months. Results of routine laboratory tests were within normal limit except elevated erythrocyte sedimentation rate. Abdominal computed tomography scan demonstrated a gastric outlet obstruction by an antral mass with mild enhancement of the area. Upper gastrointestinal endoscopy depicted an ulcerated and friable mass with an irregular shape and surface at pylorus resulting in pyloric obstruction. Endoscopic biopsy revealed only chronic gastritis with regenerative changes of epithelium. As the patient was not relieved of obstruction by conservative management, Billroth Type II gastrectomy was done. Histopathological examination of the resected specimen revealed caseating granulomas with acid-fast bacilli. Finally, the patient was diagnosed as primary gastric tuberculosis after exclusion affection of other organs and antituberculous medications was initiated. A good response to antitubercular treatment was noted after 5 months. Stomach being an uncommon site of tuberculosis and as it can occur in patients with no risk factors or characteristic symptoms, diagnosis of such rare condition remains a diagnostic enigma.

  18. Parque Madureira: Exceptional or Merely Good in Comparison?

    2016-06-01

    Full Text Available Nearly all the major urban planning initiatives associated with the ongoing transformation of Rio de Janeiro, such as the renovation of the port district, the creation of the Olympic village, and the opening of cross-municipal bus-rapid-transit lines, have been greeted by protests and criticism from architects and urban planners. One project, the Parque Madureira, a new green corridor in the city’s North Zone, has received great acclaim by Brazilian and international urbanists. Local residents seem to like it, too. Representatives of social movements, in contrast, point out that the Parque Madureira involved the same kind of favela removal criticized elsewhere. Is the Parque Madureira truly exceptional or does it merely look good in comparison to shortcomings elsewhere? What are its implications in the larger transformation of the city? This paper seeks to answer those questions by comparing the Parque Madureira both to other current urban interventions and to older parks, such as the Quinta da Boa Vista and the Aterro do Flamengo.

    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.

    Full Text Available Biographical and historical accounts suggest a link between scientific creativity and schizophrenia. Longitudinal studies of gifted children indicate that visuospatial imagery plays a pivotal role in exceptional achievements in science and mathematics. We asked whether visuospatial imagery is enhanced in individuals with schizophrenia (SZ. We compared SZ and matched healthy controls (HC on five visuospatial tasks tapping parietal and frontoparietal functions. Two aspects of visuospatial transformation, spatial location and mental imagery manipulation were examined with Paper Folding Test and Jigsaw Puzzle Task, respectively. Visuospatial intelligence was assessed with Ravens Progressive Matrices, which is associated with frontoparietal network activity. Hemispatial inattention implicating parietal function was assessed with line bisection task. Mediated by prefrontal cortex, spatial delayed response task was used to index working memory maintenance, which was impaired in SZ compared to HC. In contrast, SZ showed intact visuospatial intelligence and transformation of location. Further, SZ performed significantly better than HC on jigsaw puzzle task indicating enhanced mental imagery manipulation. Spatial working memory maintenance and mental imagery manipulation were strongly associated in HC but dissociated in SZ. Thus, we observed enhanced mental imagery manipulation in SZ but the dissociation of mental imagery from working memory suggests a disrupted frontoparietal network. Finally, while HC showed the expected leftward pseudoneglect, SZ showed increased rightward line bisection bias implicating left hemispatial inattention and impaired right parietal control of spatial attention. The current results chart a unique profile of impaired, spared and enhanced parietal-mediated visuospatial functions implicating parietal abnormalities as a biobehavioral marker for SZ. We discuss these results in relation to creative cognition.

    Fisher, William A; Kohut, Taylor; Fisher, Jeffrey D

    2009-12-01

    The current analysis considers the HIV prevention research record in the social sciences. We do so with special reference to what has been termed "AIDS Exceptionalism"- departures from standard public health practice and prevention research priorities in favor of alternative approaches to prevention that, it has been argued, emphasize individual rights at the expense of public health protection. In considering this issue, we review the historical context of the HIV epidemic; empirically demonstrate a pattern of prevention research characterized by systematic neglect of prevention interventions for HIV-infected persons; and articulate a rationale for "Prevention for Positives," supportive prevention efforts tailored to the needs of HIV+ individuals. We then propose a social psychological conceptualization of processes that appear to have influenced developments in HIV prevention research and directed its focus to particular target populations. Our concluding section considers whether there are social and research policy lessons to be learned from the record of HIV prevention research that might improve our ability to addresses effectively, equitably, and in timely fashion future epidemics that play out, as HIV does, at the junction of biology and behavior. At the first quarter century of the AIDS epidemic, it is important to weigh our accomplishments against our failures in the fight against AIDS…Future historians will conclude that we cannot escape responsibility for our failure to use effective, scientifically proven strategies to control the AIDS epidemic…They will also likely regard as tragic those instances when we allowed scarce resources to be used to support ideologically driven "prevention" that only served a particular political agenda.Editorial: A Quarter Century of AIDS .

    Regulatory requirements for new drugs have increased. Special approval procedures with priority assessment are possible for drugs with clear 'unmet medical need'. We question whether these Exceptional Circumstances (EC) or Conditional Approval (CA) procedures have led to a higher probability of serious safety issues. A retrospective cohort study was performed of new drugs approved in Europe between 1999 and 2009. The determinant was EC/CA vs. standard procedure approval. Outcome variables were frequency and timing of a first Direct Healthcare Professional Communication (DHPC). An association between approval procedure and the time from market approval to DHPC was assessed using Kaplan-Meyer survival analysis and Cox-regression to correct for covariates. In total 289 new drugs were approved. Forty-six (16.4%) were approved under EC or CA, of which seven received a DHPC (15%). This was similar to the standard approval drugs (243), of which 33 received one or more DHPC (14%, P= 0.77). The probability of acquiring a DHPC for standard approval drugs vs. EC/CA drugs during 11-year follow-up is 22% (95% CI 14%, 29%) and 26% (95% CI 8%, 44%), respectively (log-rank P= 0.726). This difference remained not significant in the Cox-regression model: hazard ratio 0.94 (95% CI 0.40, 2.20). Only drug type was identified as a confounding covariate. The EC/CA procedure is not associated with a higher probability of DHPCs despite limited clinical development data. These data do not support the view that early drug approval increases the risk of serious safety issues emerging after market approval. © 2011 The Authors.

  3. 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.

  4. 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.

    As new observing technologies and methodologies become available to any scientific discipline, unexpected discoveries often follow. This has certainly been true with regard to atmospheric electricity and lightning studies, as witnessed by the advancements allowed by regional and national lightning detection networks and radar. More recently, the ability to operationally monitor CG impulse charge moment changes (iCMC) using the National Charge Moment Change Network (CMCN), the advent of deployable high speed video imagers (to 10,000 images/sec and even faster), low-light television (LLTV) systems for detecting transient luminous events (TLEs), 3-D Lightning Mapping Arrays (LMA), and new software tools which facilitate the analysis and display of these complex data sets, is creating new areas of exploration of the lightning discharge plus delving into the characteristics of the storms which generate exceptional lightning discharges. By flagging those +CGs with large iCMCs values (>~300 C km), it is now possible in real-time to identify convective storms highly likely to generate TLEs, especially sprites. The ability of LLTVs to monitor TLEs above storms at ranges approaching 900 km (under ideal conditions) has allowed coordinated measurements, using high speed (1000-10,000 images/sec) video systems, of +CGs triggering both sprites and upward discharges from tall broadcast towers. Four such events were captured in the Rapid City area in May and June, 2010. Detailed analyses of the lightning video, the TLE imagery, and the NLDN, CMCN, and NEXRAD data are delineating the time line of these complex discharges in the context of their meteorological environment. The use of LLTVs to monitor TLEs above distant LMAs enabled studies of two MCSs traversing the Oklahoma LMA (OKLMA) in 2007. Continued analyses of these discharges, some >200 km in length, find sprite parent +CGs lowering charge to ground from altitudes varying from 4 to 8 or 9 km AGL, depending upon storm

  10. Event detection and exception handling strategies in the ASDEX Upgrade discharge control system

    Energy Technology Data Exchange (ETDEWEB)

    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. A central state machine deals with exceptions requiring coordinated action of multiple control components. DCS implements the state machine by means of pulse schedule segments containing pre-programmed waveforms to define discharge goal and control

    16 September 2010 10:00 - Bldg. 222/R-001 Digital scholarship and the changing nature of scientific publication by R.d Holliman & E. Scanlon / Open University, UK Digital media have extended the number of channels that scientists (and other academics) use to communicate and share information. Digital technologies have the potential to make all stages of the research process more visible in the public sphere, and to audiences that have, on occasion, opportunities for interaction and engagement. But digital technologies also are introducing novel demands on researchers, requiring skills and competencies on the part of scientists that are encapsulated by the concept of digital scholarship. In this presentation we explore this developing context via a case study: the publication of emails from the Climatic Research Unit at the University of East Anglia (also known as ‘climategate’). The findings of three reviews of ‘climategate’ will be discussed in terms of their i...

  5. The racialized construction of exceptionality: Experimental evidence of race/ethnicity effects on teachers' interventions.

    Science.gov (United States)

    Fish, Rachel Elizabeth

    2017-02-01

    Scholars, policy-makers, and practitioners have long argued that students of color are over-represented in special education and under-represented in gifted education, arguing that educators make racially/ethnically biased decisions to refer and qualify students with disabilities and giftedness. Recent research has called this into question, focusing on the role of confounders of race/ethnicity. However, the role of educator decisions in the disproportionality is still unclear. In this study, I examine the role of student race/ethnicity in teachers' categorization of student needs as "exceptional" and in need of special or gifted education services. I use an original survey experiment in which teachers read case studies of fictional male students in which the race/ethnicity, English Language Learner status, and exceptionality characteristics were experimentally manipulated. The teachers are then asked whether they would refer the student for exceptionality testing. My findings suggest a complex intersection of race/ethnicity and exceptionality, in which white boys are more likely to be suspected of having exceptionalities when they exhibit academic challenges, while boys of color are more likely to be suspected when they exhibit behavioral challenges. This suggests that the racialized construction of exceptionalities reflects differential academic expectations and interpretations of behavior by race/ethnicity, with implications for the subjectivity of exceptionality identification and for the exacerbation of racial/ethnic inequalities in education.

  6. The relation of cancer-prone personality to exceptional recovery from cancer: a preliminary study.

    Science.gov (United States)

    Katz, Lori S; Epstein, Seymour

    2005-01-01

    An exceptional cancer-recovered group (n = 7) was compared with 2 other recovered groups: a non-exceptional cancer-recovered group (n = 27), and a non-exceptional heart disease (HD)-recovered group (n = 31). In support of the hypothesis that mitigation of a cancer-prone personality is associated with very unusual recoveries from cancer, the exceptional cancer group reported a greater prevalence of attributes of a cancer-prone personality before diagnosis and a greater decrease in these attributes from before diagnosis to after recovery than the other groups reported. Both cancer groups reported greater stress from life events within the 2-year period preceding diagnosis, particularly for loss (or threatened loss) of a close relationship, than the HD group reported. The high internal-consistency reliability of a Cancer-prone Personality Inventory (CPPI) and its discrimination of the 2 cancer groups from the HD group make it a promising measure of a cancer-prone personality.

    2014-01-01

    In May 2012, a group of scientists and clinicians met in Athens (Greece) to consider the relevance of ageing, longevity, exceptional longevity and related genetic and non genetic markers. During this meeting, we firstly reviewed recent epidemiological and clinical studies on ageing, longevity and exceptional longevity, briefly analyzed the ageing theories and discussed successful and unsuccessful ageing also taking into account the evolutionary perspective. Secondly, we considered the three phenotypes based on the definition of ageing, longevity and exceptional longevity and the associated biomarkers. Third, we discussed proposed treatments suitable to counteract or slow down ageing. Finally, this panel produced a consensus statement to highlight the importance of ageing, longevity and exceptional longevity, since this is a rapidly increasing phenotype worldwide. We acknowledge that not all experts in this field may completely agree with this statement.

    Exceptional modular invariants for the Lie algebras B2 (at levels 2,3,7,12) and G2 (at levels 3,4) can be obtained from conformal embeddings. We determine the associated alge bras of quantum symmetries and discover or recover, as a by-product, the graphs describing exceptional quantum subgroups of type B2 or G2 which encode their module structure over the associated fusion category. Global dimensions are given.

    We construct energy-dependent potentials for which the Schrödinger equations admit solutions in terms of exceptional orthogonal polynomials. Our method of construction is based on certain point transformations, applied to the equations of exceptional Hermite, Jacobi and Laguerre polynomials. We present several examples of boundary-value problems with energy-dependent potentials that admit a discrete spectrum and the corresponding normalizable solutions in closed form.

    Full Text Available Objective  To explore the clinical characteristics, reasons for misdiagnosis and treatment of ectopic pregnancies in exceptional sites. Methods  A retrospective analysis was performed based on the clinical data of 163 patients with ectopic pregnancy in exceptional site concerning clinical characteristics, type of ectopic pregnancy, preoperative diagnosis and misdiagnosis rate, and treatment and outcomes in our hospital from Jan. 2007 to Jun. 2012. Results  The incidence of exceptional site ectopic pregnancy accounted for 14.82% (163/1100 of the total number of ectopic pregnancy occurring during the same period, and the preoperative diagnosis rate was 49.7%, the misdiagnosis rate was 50.3%. Of the exceptional site ectopic pregnancy, 8 cases were cervical pregnancy, 3 were abdominal pregnancy, 37 cesarean section scar pregnancy, 44 uterine horn pregnancy, 54 interstitial part of Fallopian tube pregnancy, 1 retroperitoneal pregnancy, 15 ovarian pregnancy and 1 uterine intramural pregnancy. Conclusion  Ectopic pregnancy in exceptional sites is usually accompanied by atypical clinical features, so it is hard to diagnose exactly. It is necessary to raise our ability to recognize the characteristic of ectopic pregnancy in an exceptional site, so as to make a right diagnosis and treatment, and reduce misdiagnosis and serious consequences.

    United Network for Organ Sharing (UNOS) policy enables listing exceptions to avoid penalizing patients with waitlist mortality not captured by standard criteria. Outcomes among patients listed by exception have not been analyzed. We performed a retrospective analysis of pediatric (≤17 years of age, n = 4,706) listings (2006 to 2015) for primary, isolated heart transplantation within the UNOS data set, assessing Status 1A exception (n = 211, 4.5%) use across regions and patient characteristics and evaluating waitlist outcomes compared with candidates listed using standard criteria. Death or removal for reason other than transplant did not differ between exception and standard criteria patients at 1 month (11.7% vs 16.2%, p = not statistically significant [NS]), 2 months (18.2% vs 29.0%, p = 0.11) or overall (16.1% vs 22.0%, p = NS) on the waitlist. Rates were higher than among Status 1B patients (1 month: 2.8%; 2 months: 5.6%; overall: 14.9%; p < 0.0001). The cumulative incidence of competing risks (transplantation, death/removal for reasons other than transplant and removal) did not differ when comparing Status 1A exception patients with Status 1A standard criteria patients. Use of 1A exceptions varied across UNOS regions (1.9% to 22.3%, p < 0.0001). Risk-adjusted modeling identified patients more (hypertrophic cardiomyopathy: odds ratio [OR] = 2.8, 95% confidence interval [CI] 1.5 to 5.0; restrictive cardiomyopathy: OR = 2.7, 95% CI 1.7 to 4.3) and less (low socioeconomic status: OR = 0.7, 95% CI 0.5 to 1.0) likely to use an exception. Use of exceptions was uncorrelated with regional outcomes. Waitlist mortality among Status 1A exception patients is similar to that among those listed by standard criteria. However, variation in exception use across geography and demography may contribute to inequities in access to transplantation, particularly for those with low socioeconomic status. Standardization of practices may decrease regional variation and minimize

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

    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.

  17. Exceptions to the rule of informed consent for research with an intervention.

    2016-02-06

    In specific situations it may be necessary to make an exception to the general rule of informed consent for scientific research with an intervention. Earlier reviews only described subsets of arguments for exceptions to waive consent. Here, we provide a more extensive literature review of possible exceptions to the rule of informed consent and the accompanying arguments based on literature from 1997 onwards, using both Pubmed and PsycINFO in our search strategy. We identified three main categories of arguments for the acceptability of a consent waiver: data validity and quality, major practical problems, and distress or confusion of participants. Approval by a medical ethical review board always needs to be obtained. Further, we provide examples of specific conditions under which consent waiving might be allowed, such as additional privacy protection measures. The reasons legitimized by the authors of the papers in this overview can be used by researchers to form their own opinion about requesting an exception to the rule of informed consent for their own study. Importantly, rules and guidelines applicable in their country, institute and research field should be followed. Moreover, researchers should also take the conditions under which they feel an exception is legitimized under consideration. After discussions with relevant stakeholders, a formal request should be sent to an IRB.

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

    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?

  19. 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.

  20. 'Clusters' as Explanations for the Exceptional Export Success of the Danish Furniture Industry?

    DEFF Research Database (Denmark)

    Howells, John; Hedemann, Lars

      The Danish furniture industry is exceptional by its export intensity and degree of internationalisation (post-2000 over 80% of income is from exports). We test the 'localised learning' theory in which it is proposed that knowledge transfer within clusters of firms explains the achievement...... firms account for more than 50% of industry turnover. Manufacture is not the major activity of most of these firms, they are not 'clustered' in the manner of the craft manufacturers and they deny having economically beneficial relations to other firms in the craft manufacturing region....... of the exceptional export intensity of this industry. We propose a more plausible path dependent explanation in which an early and exceptional international marketing effort created demand-induced growth and internationalisation of this manufacturing industry. Thereafter the industry proved able to substitute new...

  2. Cross-polarization mode coupling and exceptional points in photonic crystal slabs

    Science.gov (United States)

    Bykov, Dmitry A.; Doskolovich, Leonid L.

    2018-01-01

    We study exceptional points that occur in photonic crystal slabs due to cross-polarization (TE-TM) mode coupling. To do this, we develop spatiotemporal coupled-mode theory that describes optical properties of photonic crystal slabs supporting TE and TM modes in the case of conical mount. The developed theory suggests that by tuning the in-plane wave numbers of the incident light one can make two modes of the structure coalesce, which results in an exceptional point. The developed theory provides simple analytical expressions for the exceptional point position and the line shape of the corresponding resonance. The parameters of the proposed model can be rigorously estimated by a numerical calculation of the S-matrix poles of the structure. We show that the proposed analytical model with the estimated parameters is in good agreement with the presented full-wave simulations.

  3. From exceptional field theory to heterotic double field theory via K3

    Science.gov (United States)

    Malek, Emanuel

    2017-03-01

    In this paper we show how to obtain heterotic double field theory from exceptional field theory by breaking half of the supersymmetry. We focus on the SL(5) exceptional field theory and show that when the extended space contains a generalised SU(2)-structure manifold one can define a reduction to obtain the heterotic SO(3 , n) double field theory. In this picture, the reduction on the SU(2)-structure breaks half of the supersymmetry of the exceptional field theory and the gauge group of the heterotic double field theory is given by the embedding tensor of the reduction used. Finally, we study the example of a consistent truncation of M-theory on K3 and recover the duality with the heterotic string on T 3. This suggests that the extended space can be made sense of even in the case of non-toroidal compactifications.

  4. Expanding our understanding of sovereign power: on the creation of zones of exception in forensic psychiatry.

    Jacob, Jean Daniel; Foth, Thomas

    2013-07-01

    The purpose of this paper is to engage with the readers in a theoretical reflection on nursing practices in forensic psychiatric settings. In this paper, we argue that practices of exclusion in forensic psychiatric settings share some common ground with Agamben's description of sovereign power and, consequently, the possible creation of zones of exception in this environment. The concept of exception is, therefore, purposely used to shift our thinking, highlight the political forces surrounding exclusionary practices in forensic psychiatric nursing, and explore the ethical tensions that arise for nurses who become entangled in the control of these zones of exception. We argue that ethical and political discussions regarding this phenomenon are necessary if we wish to further understand the complexities of this field of practice and promote constructive change. © 2013 John Wiley & Sons Ltd.

  5. The effect of aging on the brain network for exception word reading.

    Provost, Jean-Sebastien; Brambati, Simona M; Chapleau, Marianne; Wilson, Maximiliano A

    2016-11-01

    Cognitive and computational models of reading aloud agree on the existence of two procedures for reading. Pseudowords (e.g., atendier) are correctly read through subword processes only while exception words (e.g., pint) are only correctly read via whole-words processes. Regular words can be correctly read by means of either way. Previous behavioral studies showed that older adults relied more on whole-word processing for reading. The aim of the present fMRI study was to verify whether this larger whole-word reliance for reading in older adults was reflected by changes in the pattern of brain activation. Both young and elderly participants read aloud pseudowords, exception and regular words in the scanner. Behavioral results reproduced those of previous studies showing that older adults made significantly less errors when reading exception words. Neuroimaging results showed significant activation of the left anterior temporal lobe (ATL), a key region implicated in whole-word reading for exception word reading in both young and elderly participants. Critically, ATL activation was also found for regular word reading in the elderly. No differences were observed in the pattern of activation between regular and pseudowords in the young. In conclusion, these results extend evidence on the critical role of the left ATL for exception word reading to elderly participants. Additionally, our study shows for the first time from a developmental point of view that the behavioral changes found in reading during normal aging also have a brain counterpart in the reading network changes that sustain exception and regular word reading in the elderly.

  20. Resolutions of Identity for Some Non-Hermitian Hamiltonians. I. Exceptional Point in Continuous Spectrum

    Directory of Open Access Journals (Sweden)

    Alexander A. Andrianov

    2011-12-01

    Full Text Available Resolutions of identity for certain non-Hermitian Hamiltonians constructed from biorthogonal sets of their eigen- and associated functions are given for the spectral problem defined on entire axis. Non-Hermitian Hamiltonians under consideration possess the continuous spectrum and the following peculiarities are investigated: (1 the case when there is an exceptional point of arbitrary multiplicity situated on a boundary of continuous spectrum; (2 the case when there is an exceptional point situated inside of continuous spectrum. The reductions of the derived resolutions of identity under narrowing of the classes of employed test functions are revealed. It is shown that in the case (1 some of associated functions included into the resolution of identity are normalizable and some of them may be not and in the case (2 the bounded associated function corresponding to the exceptional point does not belong to the physical state space. Spectral properties of a SUSY partner Hamiltonian for the Hamiltonian with an exceptional point are examined.

  11. Exceptional points in the elliptical three-disk scatterer using semiclassical periodic orbit quantization

    Science.gov (United States)

    Liebermann, Niklas; Main, Jörg; Wunner, Günter

    2017-05-01

    The three-disk scatterer has served as a paradigm for semiclassical periodic orbit quantization of classical chaotic systems using Gutzwiller's trace formula. It represents an open quantum system, thus leading to spectra of complex eigenenergies. An interesting general feature of open quantum systems described by non-Hermitian operators is the possible existence of exceptional points where not only the complex eigenvalues but also their respective eigenvectors coincide. Using Gutzwiller's periodic orbit theory we show that exceptional points exist in a three-disk scatterer if the system's geometry is modified by extending the system from circular to elliptical disks. The extension is implemented in such a way that the system's characteristic C3{v} symmetry is preserved. The two-dimensional parameter plane of the system is then spanned by the distance between and the excentricity of the elliptical disks. As typical signatures of exceptional points we observe the permutation of two resonances when an exceptional point is encircled in parameter space, and a non-Lorentzian resonance line shape in the weighted density of states.

    2012-12-01

    Full Text Available Background and Aim: Reading skills, a complicated process, should be learnt and solely is not depend on sounds conforming with the written symbols on a page. Readers will be able to understand and perceive the deeper meaning of the text based on their experiences and knowledge obtained through reading. This research aimed to compare hearing-impaired students' reading literacy in exceptional and ordinary schools in Iran.Methods: This cross-sectional study was done on 28 hearing-impaired students of the 4th year of primary exceptional and ordinary schools of Shahr-e-Ray and Shahryar cities, Iran, using the Progress in International Reading Literacy Study (PIRLS 2006 booklets. Comparative statistical analysis was performed using Student's t-test.Results: The hearing-impaired students in ordinary schools had significantly (p<0.05 higher scores [mean (SD] in reading literacy [3.67 (1.74], comprehension of informational contents [4.21 (2.48], and comprehension of literary contents [3.14(1.23] than hearing-impaired students in exceptional schools [1.78 (1.06, 1.92 (1.49, and 1.64 (1.62, respectively].Conclusion: Hearing-impaired students in ordinary schools meaningfully had higher performance of reading skills in comparison with hearing-impaired students in exceptional schools. It seems that an appropriate cultural bed should be provided in order to conduct these students and accept them in ordinary schools.

  14. Exceptionally old mice are highly resistant to lipoxidation-derived molecular damage.

    Science.gov (United States)

    Arranz, Lorena; Naudí, Alba; De la Fuente, Mónica; Pamplona, Reinald

    2013-06-01

    Membrane unsaturation plays an important role in the aging process and the determination of inter-species animal longevity. Furthermore, the accumulation of oxidation-derived molecular damage to cellular components particularly in the nervous and immune systems over time leads to homeostasis loss, which highly influences age-related morbidity and mortality. In this context, it is of great interest to know and discern the degree of membrane unsaturation and the steady-state levels of oxidative damage in both physiological systems from long-lived subjects. In the present work, adult (28 ± 4 weeks), old (76 ± 4 weeks) and exceptionally old (128 ± 4 weeks) BALB/c female mice were used. Brain and spleen were analysed for membrane fatty acid composition and specific markers of protein oxidation, glycoxidation and lipoxidation damage, i.e. glutamic semialdehyde, aminoadipic semialdehyde, carboxyethyl-lysine, carboxymethyl-lysine and malondialdehyde-lysine, by gas chromatography-mass spectrometry. The results showed significantly lower peroxidizability index in brain and spleen from exceptionally old animals when compared to old specimens. The higher membrane resistance to lipid peroxidation and lower lipoxidation-derived molecular damage found in exceptionally old animals was associated with a significantly lower desaturase activity and peroxisomal β-oxidation. Protein oxidation markers in brain and spleen from adult and exceptionally old animals showed similar levels, which were higher in old mice. In addition, the higher levels of the glycoxidation-derived marker observed in exceptionally old animals, as well as in adult mice, could be considered as a good indicator of a better bioenergetic state of these animals when compared to the old group. In conclusion, low lipid oxidation susceptibility and maintenance of adult-like protein lipoxidative damage could be key mechanisms for longevity achievement.

    2016-06-22

    Zeolitic Imidazolate Frameworks (ZIFs) have emerged as a novel class of porous metal-organic frameworks (MOFs) for catalysis application because of their exceptional thermal and chemical stability. Inspired by the broad absorption of ZIF-67 in UV-visible-near IR region, we explored its excited state and charge separation dynamics, properties essential for photocatalytic applications, using optical (OTA) and X-ray transient absorption (XTA) spectroscopy. OTA results show that an exceptionally long-lived excited state is formed after photoexcitation. This long-lived excited state was confirmed to be the charge separated state with ligandto-metal charge transfer character using XTA. The surprisingly long-lived charge separated state, together with its intrinsic hybrid nature, all point to its potential application in heterogeneous photocatalysis and energy conversion.

    Foster, Angel M; Arnott, Grady; Parniak, Simone; LaRoche, Kathryn J; Trussell, James

    2015-01-01

    Since 1979, US federal appropriations bills have prohibited the use of federal funds from covering abortion care for Peace Corps volunteers. There are no exceptions; unlike other groups that receive health care through US federal funding streams, including Medicaid recipients, federal employees, and women in federal prisons, abortion care is not covered for volunteers even in cases of life endangerment, rape, or incest. We interviewed 433 returned Peace Corps volunteers to document opinions of, perceptions about, and experiences with obtaining abortion care. Our results regarding the abortion experiences of Peace Corps volunteers, especially those who were raped, bear witness to a profound inequity and show that the time has come to lift the "no exceptions" funding ban on abortion coverage.

    2016-01-01

    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.

  19. Stark resonances for a double delta quantum well: crossing scenarios, exceptional points and geometric phases

    CERN Document Server

    Korsch, H J

    2003-01-01

    The complex energy resonances of a double delta potential well in a constant (Stark) field are studied. Varying the two system parameters (well distance and field strength) we investigate the behaviour of the resonance energies and wavefunctions both analytically and numerically. Different crossing scenarios for the real and imaginary parts of two resonance energies are observed and compared with a simple two-state model. In addition, a point in parameter space where both the real and imaginary parts of the two energies degenerate, an exceptional point, is found. Varying the system parameters around this exceptional point, the behaviour of energies and wavefunctions is discussed and the corresponding geometric phases, or Berry phases, for this non-Hermitian system are considered.

    It is commonly accepted that the combination of the anisotropic shape and nanoscale dimensions of the mineral constituents of natural biological composites underlies their superior mechanical properties when compared to those of their rather weak mineral and organic constituents. Here, we show that the self-assembly of nearly spherical iron oxide nanoparticles in supercrystals linked together by a thermally induced crosslinking reaction of oleic acid molecules leads to a nanocomposite with exceptional bending modulus of 114 GPa, hardness of up to 4 GPa and strength of up to 630 MPa. By using a nanomechanical model, we determined that these exceptional mechanical properties are dominated by the covalent backbone of the linked organic molecules. Because oleic acid has been broadly used as nanoparticle ligand, our crosslinking approach should be applicable to a large variety of nanoparticle systems.

    2011-01-01

    This article examines how the GATT Article XXIV regional trade agreement (RTA) exception can be strengthened to curb the proliferation of RTAs that maintain questionable levels of trade liberalization. The lack of rigorous application of the 'substantially all the trade' requirement and the use of rules of origin in a restrictive manner are persistent problems that have led to the exclusion of products that should otherwise be part of trade liberalization under RTAs. To provide the discipline...

    Full Text Available Secretory breast carcinoma is an exceptionally rare mammary gland neoplasia described mainly in adult females and children of both sexes, and very rarely in the elderly. It has particular histopathological and immunohistochemical features and a favorable prognosis. We report the case of a 79-year-old Hispanic woman with a palpable breast mass. Currently, the patient is disease free after a follow- up period of 6 years without local recurrence or axillary lymph-nodes nor distant metastases.

    We investigate theoretically charge migration following prompt double ionization of a polyatomic molecule (C$_2$H$_4$BrI) and find that for double ionization, correlation-driven charge migration appears to be particularly prominent, i.e., we observe exceptionally rich dynamics solely driven by the electron-electron interaction even in the situation when the electrons are emitted from outer-valence orbitals. These strongly correlated electron dynamics are witnessed in the theoretically determi...

    2017-09-01

    Current Model for End-Stage Liver Disease (MELD) exception points provided to patients with hepatocellular cancer (HCC) are not based on outcome data and advantage these patients compared to those listed based on laboratory values (LABMELD). We sought to develop a data-based assignment for exception points for patients with HCC that equalizes outcomes among HCC and LABMELD patients. We used Scientific Registry of Transplant Recipients data to compare patients listed with HCC who received exception points versus patients listed with LABMELD. Nation- and region-specific data were examined for (1) a composite outcome for adverse events of death, delisting, or becoming ineligible for transplant; and (2) transplant rate. We also determined MELD progression rates for LABMELD patients. Candidates listed with LABMELD scores were compared with those listed with 22 exception points for HCC (HCC22) to determine the LABMELD for which statistical parity was achieved for our composite outcome. HCC22 candidates time to adverse event were comparable to LABMELD scores of 16 (LABMELD16) candidates (range, 15-19), whereas time to transplant was comparable to LABMELD22 candidates (range, 21-23). LABMELD22 candidates had 2.1 times greater risk of adverse event compared with HCC22 (95% confidence interval, 1.9-2.4; range, 1.5-2.4). Progression among LABMELD16 candidates whose scores did not improve was similar across regions and averaged 0.94 points/month (95% confidence interval, 0.88-0.99, range 0.80-1.04). To equalize the occurrence of an adverse outcome, the proper listing MELD for patients with HCC is 16, with approximately 1 additional point/month. These results provide a data-driven algorithm to increase fairness in listing priority.

    In the last decade, the southeast region of Brazil has been suffering severe water shortages. Here, we propose to compute the expected drought period length to characterize the drought events in the region of São Paulo. We report the unique properties of the exceptional drought event during the austral summer 2014 by showing the differences and similarities to the very dry season in 2001 and the mild dry seasons in 2006 and 2015. Furthermore, we investigate the correlations of the abnormal precipitation deficit with the ocean and atmospheric patterns. In comparison to other drought events, we validate the hypothetical mechanism that underlies the exceptional drought 2014: (1) The existence of an anomalous high pressure center in the area acts as a blocking mechanism that prevents moisture transport from the Amazon and passage of cold front systems from south Brazil. This blocking high has been observed in all dry seasons considered, with much larger magnitude in 2014. (2) The much faster increasing trend of the anomalous sea surface temperature acts as a strong feedback which intensified the extreme climate conditions. The unprecedented increasing trend of the SST in 2014 was not observed in other climate variables representing a high pressure center. Therefore, we conclude that the exceptional drought 2014 was enhanced by the feedback mechanism of anomalous warming of SST in the South Atlantic Oceans, which was resulted from the anomalous high pressure.

    2017-07-11

    In recent years, the Swiss Federal Office of Public Health (FOPH) granted exceptional licenses for the medical use of cannabinoids, typically for 6 months with possible extensions. A systematic review of cannabinoids for medical use commissioned by the FOPH supports the use of cannabinoids for the treatment of chronic pain and spasticity. However, little is known about the patients treated with cannabinoids. We aimed to study medical uses of cannabinoids as part of the FOPH's programme of exceptional licenses. We examined all requests for medical use of cannabinoids sent to FOPH in 2013 and 2014. A standardised data sheet was developed to extract data from the files of approved requests. We extracted the duration of the licence, the year it was granted, and the payer of the therapy. At the level of the patient we collected the date of birth, sex, region of residence, diagnosis and the indication. Ethical approval was granted by the Ethics Committee of the Canton of Bern. We analysed 1193 patients licenced for cannabinoid treatment in 2013 or 2014. During 2013, 542 patients were treated under the exceptional licencing programme (332 requesting physicians) compared with 825 in 2014 (446 physicians). Over half of patients (685; 57%) were women. The mean age was 57 years (standard deviation 15.0), chronic pain (49%) and spasticity (40%) were the most common symptoms, and co-medication was reported for 39% of patients. Seventy-eight different diagnoses were recorded, including multiple sclerosis (257 patients, 22%), soft tissue disorders (119, 10%), dorsalgia (97, 8.1%), spinal muscular atrophy (65, 5.5%) and paraplegia/tetraplegia (62, 5.2%). Licence extensions were granted to 143 patients (26.4%) in 2013 and 324 patients (39.3%) in 2014. There were substantial regional variations of the rates of patients treated with cannabinoids. On average, eight patients per 100 000 residents received an exceptional licence. Most patients (1083, 91%) paid out of pocket. Exceptional

  13. From Errors Treatment to Exceptions Treatment Regarding the Execution Control over Visual Basic Programs

    Full Text Available In order to comply with the quality standards and with the best practices, the execution of the professional programs must be rigorously controlled so that to avoid occurrence of unpredictable situations that might generate anomalies and could lead to computer blockage, forced termination of the execution and data loss. In traditional programming languages, including Visual Basic 6, the concept of error is extremely evolved. It is considered as error any situation in which the program fails to execute correctly, regardless if such anomaly is generated by a software or hardware cause. Nowadays the modern platforms, including VB.NET have introduced a new concept: exception. Unfortunately, perhaps by mistake, exception is assimilated by many IT specialists as an exceptional (extraordinary situation or a rare situation.We agree with the opinion of those IT specialists asserting that error is strictly dependant on the programmer, when he/she fails in correctly generating the application’s structures, whilst exception is a situation not fitting in the usual natural execution or as desired by the programmer or user, without meaning that it occurs more often or more rarely.Designing robust programs implies for such not to terminate abnormally or block, not even upon receiving improper parameters. Two aspects are referred to: the behavior regarding low level errors (caused by the operation system, memory allocation, reading/writing in files or hardware malfunctions and the reaction to the user’s errors, such as providing incorrect input data or incorrect use of operations in respect with their sequences. Notwithstanding what platform is used in designing the programs and regardless the controversy between the specialists, in order for the execution to be terminated under the program’s control, the commands that might generate anomalies and interruptions should be strictly monitored. Implicitly, the execution control

    The paper contains a statistical analysis of exceptional solar events and daily numbers of deaths from diseases from ICD-10 group VI. Diseases of the nervous system, group IX. Diseases of the circulatory system, and overall daily numbers of deaths in the Czech Republic. It is demonstrated that neurological diseases exhibit greater instability during the period of rising and falling solar activity. Specifically, we study the daily number of deaths separately for both sexes at the age groups under 39 and 40+ during the Solar Cycles No. 23 and No. 24. We focus mainly on exceptional solar events such as a "Bastille Day event" on July 14, 2000 (class X5), "Halloween solar storm" on October 28, 2003 (class X17), and events on January 7, 1997, April 2, 2000 (class X20), or September 7, 2005 (class X15). Special attention is given to "St. Patrick's Day storm" on March 17, 2015, the strongest geomagnetic storm of the Solar Cycle No. 24 that occurred following a coronal mass ejection (CME). We investigate changes in daily numbers of deaths during 1 month before and 1 month after these exceptional solar events. We take specific storm dynamics of geophysical parameters into consideration, and we also apply the results of risky characteristics of expositions by ionospheric and geomagnetic parameters. It is verified that, for diseases of the nervous system, women are generally more sensitive than men. On the contrary, this differences between men and women are not found for diseases of the circulatory system. Our findings suggest that the impact of hazardous space weather conditions on human health depends on the specific course and strength of individual solar storm.

    News media are used for community education and notification in exception from informed consent clinical trials, yet their effectiveness as an added safeguard in such research remains unknown. We assessed the number of callers requesting opt-out bracelets after each local media report and described the errors and content within each media report. We undertook a descriptive analysis of local media trial coverage (newspaper, television, radio, and Web log) and opt-out requests during a 41-month period at a single site participating in an exception from informed consent out-of-hospital trial. Two nontrial investigators independently assessed 41 content-based media variables (including background, trial information, graphics, errors, publication information, and assessment) with a standardized, semiqualitative data collection tool. Major errors were considered serious misrepresentation of the trial purpose or protocol, whereas minor errors included misinformation unlikely to mislead the lay reader about the trial. We plotted the temporal relationship between opt-out bracelet requests and media reports. Descriptive information about the news sources and the trial coverage are presented. We collected 39 trial-related media reports (33 newspaper, 1 television, 1 radio, and 4 blogs). There were 13 errors in 9 (23%) publications, 7 of which were major and 6 minor. Of 384 requests for 710 bracelets, 310 requests (80%) occurred within 4 days after trial media coverage. Graphic timeline representation of the data suggested a close association between media reports about the trial and requests for opt-out bracelets. According to results from a single site, local media coverage for an exception from informed consent clinical trial had a substantial portion of errors and appeared closely associated with opt-out requests.

  16. The Fynbos and sUcculent Karoo biomes do not have exceptional local ant richness.

    Directory of Open Access Journals (Sweden)

    Brigitte Braschler

    Full Text Available BACKGROUND: The Fynbos (FB and Succulent Karoo biomes (SKB have high regional plant diversity despite relatively low productivity. Local diversity in the region varies but is moderate. For insects, previous work suggests that strict phytophages, but not other taxa, may have high regional richness. However, what has yet to be investigated is whether the local insect species richness of FB and SKB is unusual for a region of this productivity level at this latitude, and whether regional richness is also high. Here we determine whether this is the case for ants. METHODOLOGY/PRINCIPAL FINDINGS: We use species richness data from pitfall traps in the FB and SKB in the Western Cape Province, South Africa and a global dataset of local ant richness extracted from the literature. We then relate the globally derived values of local richness to two energy-related predictors--productive energy (NDVI and temperature, and to precipitation, and compare the data from the FB and SKB with these relationships. We further compare our local richness estimates with that of similar habitats worldwide, and regional ant richness with estimates derived from other regions. The local ant species richness of the FB and SKB falls within the general global pattern relating ant richness to energy, and is similar to that in comparable habitats elsewhere. At a regional scale, the richness of ants across all of our sites is not exceptional by comparison with other regional estimates from across the globe. CONCLUSIONS/SIGNIFICANCE: Local richness of ants in the FB and SKB is not exceptional by global standards. Initial analyses suggest that regional diversity is also not exceptional for the group. It seems unlikely that the mechanisms which have contributed to the development of extraordinarily high regional plant diversity in these biomes have had a strong influence on the ants.

    Directory of Open Access Journals (Sweden)

    Primož Vitez

    2013-12-01

    Full Text Available Originairement une conception de politique culturelle, lʼexception française est un réflexe de sauvegarde par lequel la culture française a essayé de sʼaffronter à lʼhégémonie anglophone et anglographe après la seconde guerre mondiale et, plus tard, à la mondialisation. Mais la compréhension de lʼexception française ne peut pas sʼarrêter sur ses composantes juridiques et politiques : le goût français de la spécificité est profondément encodé dans la langue française, symptôme inhérent de lʼancien prestige de la francophonie. Lʼexception française est donc bien une question de langue. Le sens de lʼexception est bien celui de saisir, prendre à part : et véritablement, le français, la francophonie et les francophones se prennent à part, souvent sans le vouloir. Le français est une langue qui est essentiellement différente par rapport aux autres langues : la différence ne repose pas uniquement dans les détails de sa structure grammaticale, mais surtout, évidemment, dans lʼimage sonore générale, par laquelle le français se distancie même des langues qui ont une genèse structurelle comparable, à savoir les langues romanes. Cette différence détermine ainsi une "sous-entente" de la position auto-priviliégiée, mais aussi frustrante que les locuteurs du français langue maternelle prennent vis-à-vis dʼeux-mêmes, vis-à-vis des locuteurs non-francophones, et particulièrement vis-à-vis des locuteurs du français langue étrangère. La politique linguistique en France est basée dʼabord sur lʼexceptionnalité du français, sur le regret de son élitisme passé, et ensuite sur les postulats constitutionnels et législatifs qui garantissent formellement la sauvegarde de lʼhéritage linguistique français.

    Full Text Available The construction of a family of real Hamiltonian forms (RHF for the special class of affine 1+1-dimensional Toda field theories (ATFT is reported. Thus the method, proposed in [1] for systems with finite number of degrees of freedom is generalized to infinite-dimensional Hamiltonian systems. The construction method is illustrated on the explicit nontrivial example of RHF of ATFT related to the exceptional algebras E_6 and E_7. The involutions of the local integrals of motion are proved by means of the classical R-matrix approach.

    This is a report on a 20-year old patient who had been suffering from chronic constipation from her childhood. After radiography of the colon in double contrast in December 1986 the patient was admitted to hospital under suspicion of a perforation of the colon. The radiographic demonstration of the abdomen showed an exceptional dilatation of some segments of the colon but without any signs of perforation by free intraperitoneal gas. Subsequent examination led to the diagnosis of an idiopathic megacolon whereas a congenital as well as a symptomatic and toxic megacolon could be excluded.

    2016-01-01

    Effective non-Hermitian Hamiltonians are obtained to describe coherent perfect absorbing and lasing boundary conditions. PT -symmetry of the Hamiltonians enables to design configurations which perfectly absorb at multiple frequencies. Broadened and flat perfect absorption is predicted at the exceptional point of PT -symmetry breaking while, for a particular case, absorption is enhanced with the use of gain. The aforementioned phenomena are illustrated for acoustic scattering through Helmholtz resonators revealing how tailoring the non-Hermiticity of acoustic metamaterials leads to novel mechanisms for enhanced absorption.

It is based on an analysis of discourses about the homicide of a pregnant young woman committed by the staff member of a police department in a poor neighborhood of Buenos Aires, Argentina. The textual marks that allow accessing the meanings exposed and supported around the concept of violence are analyzed. Special attention is given to the factors that appear as indications of a violent act of greater degree. Revealing that which is considered excessive, with exception, can help in the understand of that which is normally considered as violence.

  7. Polymer:Nonfullerene Bulk Heterojunction Solar Cells with Exceptionally Low Recombination Rates

    KAUST Repository

    Gasparini, Nicola

    2017-09-01

    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.

Melanin-bearing melanosomes were suggested to preserve as organic residues in exceptionally preserved fossils, retaining distinct morphology that is associated with aspects of original color patterns. Nevertheless, these oblong and spherical structures have also been identified as fossilized bacteria. To date, chemical studies have not directly considered the effects of diagenesis on melanin preservation, and how this may influence its identification. Here we use time-of-flight secondary ion mass spectrometry to identify and chemically characterize melanin in a diverse sample of previously unstudied extant and fossil taxa, including fossils with notably different diagenetic histories and geologic ages. We document signatures consistent with melanin preservation in fossils ranging from feathers, to mammals, to amphibians. Using principal component analyses, we characterize putative mixtures of eumelanin and phaeomelanin in both fossil and extant samples. Surprisingly, both extant and fossil amphibians generally exhibit melanosomes with a mixed eumelanin/phaeomelanin composition rather than pure eumelanin, as assumed previously. We argue that experimental maturation of modern melanin samples replicates diagenetic chemical alteration of melanin observed in fossils. This refutes the hypothesis that such fossil microbodies could be bacteria, and demonstrates that melanin is widely responsible for the organic soft tissue outlines in vertebrates found at exceptional fossil localities, thus allowing for the reconstruction of certain aspects of original pigment patterns.

    We study the gauging of the orthosymplectic algebras OSp(6|4)xSO(2) and its "dual" OSp(2|4)x SO(6), both based on supergravities with the same exceptional coset SO*(12)/U(6), and gauge group SO(6)xSO(2). The two dual theories are obtained by two different truncations of gauged N=8 AdS_4 supergravity. We explicitly study the gauge sector of the two dual theories with the most general group allowed by supersymmetry. In the ungauged (super-Poincar\\'e) case they exhibit the same (large) black-hole attractor solutions with dual relations between the 1/N-BPS and non-BPS configurations. The N=6 gravity multiplet has also the exceptional property to be a {\\em zero-center module} of OSp(6|4), as it is the case for superconformal Yang--Mills theory in four dimensions based on SU(2,2|n) (PSU(2,2|4) for n=4) or OSp(n|4).

  10. 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.

  11. Ethos without nomos: the Russian–Georgian War and the post-Soviet state of exception

    2010-11-01

    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.

  12. Indirect closing of elytra by the prothorax in beetles (Coleoptera): general observations and exceptions.

    Science.gov (United States)

    Frantsevich, Leonid

    2012-02-01

    Voluntary movements of the prothorax and the elytra in tethered flying beetles and manually induced movements of these parts in fresh dead beetles were recorded in 30 species representing 14 families. Participation of prothoracic elevation in the closing of the elytra was demonstrated in three ways. (i) The elevation was always simultaneous with elytral closing, in contrast to depression and elytral opening; a rare exception occurred in Lucanus cervus, whose elytra sometimes started to close before the cessation of wing strokes and the elevation of the prothorax. (ii) The manipulated elevation always induced closing of the spread elytra; the mechanical interaction between the hind edge of the pronotum and the roots of the elytra is a universal mechanism of closing the elytra in beetles. (iii) The prevention of pronoto-elytral contact in live beetles by the excision of the hind edge of the pronotum in front of the root prevented elytral closing after normal flight. Exceptions to this rule included some beetles that were able to close their elytra after such an excision: tiger beetles and diving beetles (seldomly) and rose chafers (always). This ability in Adephaga may be explained by attachments of the muscle actuating the 4th axillary plate, which differ from the attachments in Polyphaga. Cetoniinae open their elytra only by a small amount. It is proposed that their small direct adductors in combination with the elasticity of the sclerites are enough to achieve elytral closing without additional help from the prothorax.

    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.

    There has recently been interest in relating properties of matrices drawn at random from the classical compact groups to statistical characteristics of number-theoretical L-functions. One example is the relationship conjectured to hold between the value distributions of the characteristic polynomials of such matrices and value distributions within families of L-functions. These connections are extended here to non-classical groups. We focus on an explicit example: the exceptional Lie group G{sub 2}. The value distributions for characteristic polynomials associated with the 7- and 14-dimensional representations of G{sub 2}, defined with respect to the uniform invariant (Haar) measure, are calculated using two of the Macdonald constant term identities. A one-parameter family of L-functions over a finite field is described whose value distribution in the limit as the size of the finite field grows is related to that of the characteristic polynomials associated with the seven-dimensional representation of G{sub 2}. The random matrix calculations extend to all exceptional Lie groups.

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

    Lynch, Michael

    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.

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

    Directory of Open Access Journals (Sweden)

    Nicos Trimikliniotis

    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.

    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.

    Purpose The phenotypic manifestations of cerebral cavernous malformation (CCM) disease caused by rare PDCD10 mutations have not been systematically examined, and a mechanistic link to Rho kinase (ROCK) mediated hyperpermeability, a potential therapeutic target, has not been established. Methods We analyze PDCD10-siRNA treated endothelial cells for stress fibers, ROCK activity and permeability. ROCK activity is assessed in CCM lesions. Brain permeability and CCM lesion burden is quantified, and clinical manifestations are assessed in prospectively enrolled subjects with PDCD10 mutations. Results We determine that PDCD10 protein suppresses endothelial stress fibers, ROCK activity and permeability in vitro. Pdcd10 heterozygous mice have greater lesion burden than other Ccm genotypes. We demonstrate robust ROCK activity in murine and human CCM vasculature, and increased brain vascular permeability in humans with PDCD10 mutation. Clinical phenotype is exceptionally aggressive compared to the more common KRIT1 and CCM2 familial and sporadic CCM, with greater lesion burden and more frequent hemorrhages earlier in life. We first report other phenotypic features including scoliosis, cognitive disability and skin lesions, unrelated to lesion burden or bleeding. Conclusion These findings define a unique CCM disease with exceptional aggressiveness, and they inform preclinical therapeutic testing, clinical counseling and the design of trials. PMID:25122144

    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.

    Recently, synthetic optical materials represented via non-Hermitian Hamiltonians have attracted significant attention because of their nonorthogonal eigensystems, enabling unidirectionality, nonreciprocity and unconventional beam dynamics. Such systems demand carefully configured complex optical potentials to create skewed vector spaces with a desired metric distortion. In this paper, we report optically generated non-Hermitian photonic lattices with versatile control of real and imaginary sub-lattices. In the proposed method, such lattices are generated by vector-field holographic interference of two elliptically polarized pump beams on azobenzene-doped polymer thin films. We experimentally observe violation of Friedel's law of diffraction, indicating the onset of complex lattice formation. We further create an exact parity-time symmetric lattice to demonstrate totally asymmetric diffraction at the spontaneous symmetry-breaking threshold, referred to as an exceptional point. On this basis, we provide the experimental demonstration of reconfigurable non-Hermitian photonic lattices in the optical domain and observe the purest exceptional point ever reported to date.

  2. Not an exception to the rule: the functional significance of intrinsically disordered protein regions in enzymes.

    2017-02-28

    Intrinsically disordered protein regions (IDPRs) are remarkably common and have unique and important biological functions. Enzymes have long been considered an exception to the rule of protein intrinsic disorder due to the structural requirements for catalysis. Although functionally significant IDPRs have been described in several enzymes, there has been no study quantifying the extent of this phenomenon. We have conducted a multilevel computational analysis of missing regions in X-ray crystal structures in the PDB and predicted disorder in 66 representative proteomes. We found that the fraction of predicted disorder was higher in non-enzymes than enzymes, because non-enzymes were more likely to be fully disordered. However, we also found that transferases, hydrolases and enzymes with multiple assigned functional classifications were similar to non-enzymes in terms of the length of the longest continuous stretch of predicted disorder. Both eukaryotic enzymes and non-enzymes had a greater disorder content than was seen in bacteria. Disorder at the proteome level appears to emerge in response to organismic and functional complexity, and enzymes are not an exception to this rule.

    2017-09-01

    We propose to obtain the first X-ray image of an exceptional cluster of galaxies, which stands out as being an extremely distant (z=1.7) and massive (2-5*10^14M_sun) cluster, harbouring a still-assembling BCG that is forming stars at a prodigious rate of 860M_sun/yr. Combined with our recently awarded VLA and HST data, the goal of this proposal is to: 1) determine the dynamical state of the cluster; 2) provide an independant estimate of the cluster mass; and 3) study the X-ray properties of the extreme central AGN. The observations will significantly help in our understanding of the formation and evolution of massive clusters and BCGs, as well as the role of AGN in astrophysical feedback. In summary, in 170 ks, this proposal will advance several aspects of high-z physics.

  8. Expert and exceptional performance: evidence of maximal adaptation to task constraints.

    Science.gov (United States)

    Ericsson, K A; Lehmann, A C

    1996-01-01

    Expert and exceptional performance are shown to be mediated by cognitive and perceptual-motor skills and by domain-specific physiological and anatomical adaptations. The highest levels of human performance in different domains can only be attained after around ten years of extended, daily amounts of deliberate practice activities. Laboratory analyses of expert performance in many domains such as chess, medicine, auditing, computer programming, bridge, physics, sports, typing, juggling, dance, and music reveal maximal adaptations of experts to domain-specific constraints. For example, acquired anticipatory skills circumvent general limits on reaction time, and distinctive memory skills allow a domain-specific expansion of working memory capacity to support planning, reasoning, and evaluation. Many of the mechanisms of superior expert performance serve the dual purpose of mediating experts' current performance and of allowing continued improvement of this performance in response to informative feedback during practice activities.

    Between the end of January and mid February 2012, the Italian peninsula has been subject to the influence of many advections of arctic-continental air generating a series of cyclogenesis over the central-Mediterranean Sea. This caused widely spread mainly snowy precipitation, often persistent, mostly affecting the central-southern Regions, as well as Rome and Naples. Snowfalls and low temperatures caused some sixty casualties, besides huge damage to economic and productive facilities. The analysis of a large number of nivometric monitoring points, belonging to different institutions (Meteomont, Military Aviation, Civil Protection and Universities) allowed evaluating the spatial distribution of total snowfall. Comparing these figures with those referring to past perturbation phases similar in length - recorded in the winter of 1929, 1956, 1985 and 2005 - demonstrates that the 2012 event can be considered exceptional being characterized by a higher total thickness of snow cover almost everywhere along the hills and low mountains of the Adriatic side of Central Italy.

  10. Disconjugacy, regularity of multi-indexed rationally extended potentials, and Laguerre exceptional polynomials

    Science.gov (United States)

    Grandati, Y.; Quesne, C.

    2013-07-01

    The power of the disconjugacy properties of second-order differential equations of Schrödinger type to check the regularity of rationally extended quantum potentials connected with exceptional orthogonal polynomials is illustrated by re-examining the extensions of the isotonic oscillator (or radial oscillator) potential derived in kth-order supersymmetric quantum mechanics or multistep Darboux-Bäcklund transformation method. The function arising in the potential denominator is proved to be a polynomial with a nonvanishing constant term, whose value is calculated by induction over k. The sign of this term being the same as that of the already known highest degree term, the potential denominator has the same sign at both extremities of the definition interval, a property that is shared by the seed eigenfunction used in the potential construction. By virtue of disconjugacy, such a property implies the nodeless character of both the eigenfunction and the resulting potential.

  11. Alain Badiou’s Suturing of the Law to the Event and the State of Exception

    2016-10-01

    Full Text Available This article questions whether we can posit a more radical desuturing of the law from the event: Can radical shifts in law produce events? Can the law itself be an event, thereby conditioning the very nature of the event itself, creating a new subjectivity and a new time?  I would like to argue that the law can do so. How? Badiou begins “The Three Negations” by discussing the work of the German jurist Carl Schmitt (TN 1877. I would like to argue that the state of exception, as elaborated by Carl Schmitt, can serve as the willed decision of a sovereign that brings about an event.  We can understand the sovereign as a kind of legal subject that has the force to bring about a new event, rupturing with an established order and introducing a new form of subjectivity and time.

  12. Access to special education for exceptional students in French immersion programs: An equity issue

    Directory of Open Access Journals (Sweden)

    Nancy Wise

    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 model of three coupled wave guides and third order exceptional points

    Heiss, W. D.; Wunner, G.

    2016-12-01

    A { P }{ T }-symmetric model for three interacting wave guides is investigated. Each wave guide is represented by an attractive δ-function potential being in equidistant positions. The two outer potentials are complex describing loss and gain, respectively. The real parts of the outer potentials are assumed to be equal. The major focus of the study lies on the occurrence of an exceptional point of third order and the physical effects of such singularity. While some results resemble those from similar studies with two wave guides, the three wave guides appear to have a richer structure. Emphasis is placed on the fine tuning in the approach of the EP3 as this appears to be a particular challenge for an experimental realization.

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

    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.

    Birds, dinosaurs, crocodilians, pterosaurs and their close relatives form the highly diverse clade Archosauriformes. Archosauriforms have a deep evolutionary history, originating in the late Permian, prior to the end-Permian mass extinction, and radiating in the Triassic to dominate Mesozoic ecosystems. However, the origins of this clade and its extraordinarily successful body plan remain obscure. Here, we describe an exceptionally preserved fossil skull from the Lower Triassic of Brazil, representing a new species, Teyujagua paradoxa, transitional in morphology between archosauriforms and more primitive reptiles. This skull reveals for the first time the mosaic assembly of key features of the archosauriform skull, including the antorbital and mandibular fenestrae, serrated teeth, and closed lower temporal bar. Phylogenetic analysis recovers Teyujagua as the sister taxon to Archosauriformes, and is congruent with a two-phase model of early archosauriform evolution, in response to two mass extinctions occurring at the end of the Guadalupian and the Permian.

    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 < BL < 1541.7 t

    We find the algebras of unipotent invariants of the Cox rings for all double flag varieties of complexity 0 and 1 for the exceptional simple algebraic groups; namely, we obtain presentations of these algebras in terms of generators and relations. It is well known that such an algebra is free in the case of complexity 0. In this paper, we show that, in the case of complexity 1, the algebra in question is either a free algebra or a hypersurface. A similar result for classical groups was previously obtained by the author. Knowing the structure of this algebra enables one to decompose tensor products of some irreducible representations effectively into irreducible summands and to obtain some branching rules.

    2015-10-01

    We propose to obtain deep Chandra X-ray observations of 3 exceptional high-z (z>0.5) clusters of galaxies, which stand out as extremely X-ray luminous (L X-ray>>10^44 erg/s), relaxed cool-core clusters with evidence of X-ray cavities and a previous epoch of astrophysical feedback. This proposal will double the number of z>0.57 clusters with deep Chandra observations. The observations will significantly help in our understanding of the evolution and formation of massive clusters, the role of active galactic nuclei in astrophysical feedback and the distribution of metals in clusters at high-z, and will be used to place new constraints on the dark energy and cosmology. In summary, in just 425 ks, this proposal will advance several aspects of high-z clusters physics.

    Stereotypes of outgroups help create social identificational boundaries for ingroups. When the ingroup is dominant, members employ individualist sentiments to justify their status. In this study, we build on advances in social psychological research that account for multiple outgroup stereotypes. We argue the Asian American model minority stereotype is analogous to the “cold but competent” position of perceptions toward Asians in Fiske’s stereotype content model. Asian Americans are perceived to be exceptional to other minority groups, and we hypothesize that perceived competence is associated with individualist sentiments directed at Blacks and Latinos. Using data from the National Longitudinal Study of Freshmen, we find support for our hypotheses but find that perceived coldness has no relationship to individualist sentiments. We discuss the implications and directions for further research. PMID:27478288

    Metal-organic frameworks (MOFs) show high CO2 storage capacity at room temperature. Gravimetric CO2 isotherms for MOF-2, MOF-505, Cu3(BTC)2, MOF-74, IRMOFs-11, -3, -6, and -1, and MOF-177 are reported up to 42 bar. Type I isotherms are found in all cases except for MOFs based on Zn4O(O2C)6 clusters, which reveal a sigmoidal isotherm (having a step). The various pressures of the isotherm steps correlate with increasing pore size, which indicates potential for gas separations. The amine functionality of the IRMOF-3 pore shows evidence of relatively increased affinity for CO2. Capacities qualitatively scale with surface area and range from 3.2 mmol/g for MOF-2 to 33.5 mmol/g (320 cm3(STP)/cm3, 147 wt %) for MOF-177, the highest CO2 capacity of any porous material reported.

  1. 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.

    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.

    Semantic dementia (SD) is a neurodegenerative disease that occurs following the atrophy of the anterior temporal lobes (ATLs). It is characterised by the degradation of semantic knowledge and difficulties in reading exception words (surface dyslexia). This disease has highlighted the role of the ATLs in the process of exception word reading. However, imaging studies in healthy subjects have failed to detect activation of the ATLs during exception word reading. The aim of the present study was to test whether the functional brain regions that mediate exception word reading in normal readers overlap those brain regions atrophied in SD. In Study One, we map the brain regions of grey matter atrophy in AF, a patient with mild SD and surface dyslexia profile. In Study Two, we map the activation pattern associated with exception word compared to pseudoword reading in young, healthy participants using fMRI. The results revealed areas of significant activation in healthy subjects engaged in the exception word reading task in the left anterior middle temporal gyrus, in a region observed to be atrophic in the patient AF. These results reconcile neuropsychological and functional imaging data, revealing the critical role of the left ATL in exception word reading. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available This study attempts to analyze comparatively marital satisfaction and quality of life in mothers with exceptional children and mothers with normal children. Methodology in present study is comparative. For sample, it selects 40 mothers with normal children in nursery school and preschool located in Ahvaz, 40 mothers with exceptional children under education and care in daily sanatorium, and 30 mothers with exceptional children hospitalized (nightly in Ahvaz. They are tested by a enrich questionnaire of short form with 47 questions and 36 questions of quality of life. Statistical model of one-way variance analysis is used for data analysis. Findings indicate that there is no significant difference in marital satisfaction between mothers with exceptional children in caring centers and mothers with normal children, yet there is a significant difference in quality of life (mental-physical between mothers with exceptional children and mothers with normal children. Results of study indicate that mental quality of life as dependent variable is influenced by factors such as children with mental or physical disability as independent variables. Birth of an exceptional child reduces mental quality of life. Results show that not presence of exceptional child for full-time is highly effective on physical quality of life.

    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

    The connectivity of the neurons of the olfactory bulb is highly idiosyncratic and constitutes an exception to the general plan of how neurons, and especially cortical neurons, construct circuits. The majority of synaptic contacts in the circuits of the cortex are axo-dendritic. In these contacts, the axon is the presynaptic element, which transmits the signal, and the dendrite is the postsynaptic element, which receives the signal. However, the majority of synaptic contacts in the circuits of the olfactory bulb are dendro-dendritic. In fact, most of the neurons of the olfactory bulb lack an axon. Moreover, a high percentage of the dendro-dendritic synapses are reciprocal. This means that the roles of presynaptic and postsynaptic element are not clearly defined, in clear contrast with the universality of unidirectional synaptic transmission in the cortex and elsewhere in the central nervous system. In this review, we analyze and discuss some peculiarities of the circuits of the olfactory bulb. Copyright © 2013 Wiley Periodicals, Inc.

  11. Referral decisions of teachers and school psychologists for twice-exceptional students

    Hoffman, Jennifer Marie

    The accurate and timely referral and identification of twice-exceptional students remains a challenge. In a statewide study, the referral decisions for both special education and gifted programming evaluations made by four participant groups (i.e., general education teachers, special education teachers, gifted education teachers, and school psychologists) were compared. Participants were randomly assigned to read one of three identically described students in a vignette that differed only in the presence of a diagnostic label--- autism spectrum disorder (ASD), specific learning disability (SLD), or no diagnostic label. In all, special education teachers made the most special education referrals, while gifted education teachers made the most gifted programming referrals, both regardless of the diagnostic label present. The students with diagnostic labels were recommended for special education referrals significantly more than for gifted programming, while this difference was not evident in the no diagnostic label condition. Moreover, the student with the ASD label was the most likely to be referred for evaluations for both special education and gifted programming out of all three vignette conditions. Overall findings indicated the importance of considering the referral source as well as how the presence of a diagnostic label might influence educational referral decisions, particularly in how this might influence overall multidisciplinary team decisions for these unique learners.

  12. Astronomical forcing of an exceptionally long Sahel wet phase during Marine Isotope Stage 11c

    Prange, Matthias; Rachmayani, Rima; Schulz, Michael

    2016-04-01

    Increased rainfall and expanded vegetation over North Africa during the early-to-mid Holocene was related to an intensified West African monsoon and a northward displacement of the monsoon trough triggered by astronomical forcing. Similar wet phases are evidenced for earlier interglacials including Marine Isotope Stage (MIS) 11c (ca. 425-395 ka before present). We performed a series of time slice simulations using the comprehensive coupled climate model CCSM3 including a dynamic vegetation module in order to examine the dynamics of the MIS 11c humid period. Proxy records from a marine sediment core site off Northwest Africa suggest an extremely long Sahel/Sahara wet phase during MIS 11c between ca. 420 and 405 ka ago, revealing that North African rainfall changes did not simply follow local summer insolation. Instead, the climate model simulations suggest an important role of the obliquity-driven intra-hemispheric insolation gradient in forcing Sahelian rainfall changes. The specific phasing between precession and obliquity during the MIS 11c interglacial resulted in the exceptionally long wet phase in the Sahel region. The early part of this wet phase was primarily induced by northern-hemispheric differential warming in response to maximum obliquity around 416 ka before present. As such, this interval may well serve as an analog for potential future Sahel rainfall increase induced by strong northern hemisphere extratropical warming.

    Full Text Available In this essay I would like to focus on “The Beast and the Sovereign”—and especially the Second Volume—as being something of an exception to Derrida’s usual hesitations about sovereignty. In other works, such as “Rogues”, Derrida displays a deep ambivalence about sovereignty insofar as for all of his condemnation of sovereign authority, he fears that what might replace it could be even worse (and, to be fair, he also sees positive aspects of sovereignty as well. In “The Beast and the Sovereign,” we find evidence of this ambivalence as well but here, Derrida comes a bit closer to the kind of position advocated by Walter Benjamin wherein sovereignty is an idolatrous practice of politics one which must not be eliminated so much as subverted. In particular, I focus on Derrida’s reading in Volume II of “Robinson Crusoe” as a text that both founds the sovereign subject and subverts it (by revealing its vulnerability, its fictional nature. In looking at how the book disappoints as much as it answers sovereign phantasms of authority and unity, I argue that Derrida transfers his own ambivalence about sovereignty to sovereignty itself, subverting and rupturing its central tenets in the process.

    Directory of Open Access Journals (Sweden)

    Benjamin Thompson

    2014-02-01

    Full Text Available The recent decision in the US Supreme Court Kiobel case applied the presumption against extraterritoriality towards the Alien Tort Statute, decreasing the potential scope of tort actions that can be made against corporations for severe human rights violations. In light of the growing influence of multinational corporations and the lack of any international law regime to regulate corporate wrongdoing, this decision might be seen as a blow against one of the few potential avenues for justice for those victims of corporate human rights violations. The Alien Tort Statute is not a jurisdictional statute that allows for claims under international law but is rather a uniquely American cause of action unconnected to international law. The question remains whether an extension of American law to provide remedies for severe corporate human rights abuses can be justified in the absence of any such remedies existent in international law. This article will attempt to answer this question applying criteria developed by leading scholars in response to American exceptionalism. It will argue that the Kiobel decision, rather than being detrimental to holding corporations accountable, actually addresses many of the negative aspects of extraterritorial litigation whilst preserving some possibility of remedy for victims of severe human rights violations by corporations.

  15. A nanoporous, ultrahydrophobic aluminum-coating process with exceptional dropwise condensation and shedding properties

    2017-04-01

    Many studies have shown that dropwise condensation can enhance air-side heat transfer coefficients by at least an order of magnitude relative to filmwise condensation. However, among the hundreds of superhydrophobic surface-modification processes previously reported, there remains a lack of coating methods that enable stable dropwise condensation and can be applied to aluminum—by far the most common material for the air side of heat exchangers, e.g. in air conditioning. Here we present a bottom-up synthesis technique to grow zinc oxide-based films on to aluminum with tunable nanoporosity and strongly re-entrant surface features. These surfaces exhibit exceptional static water contact angles of up to 178° with a hysteresis less than 3° and a slide angle of 1°. We have further characterized the surfaces in the presence of six different liquids, and show that our optimal surface can repel even dipropylene glycol with a contact angle of 124°, even though its surface tension is less than half that of water. Crucially, we have also tested our films under water-condensing conditions in flowing air, characterizing the droplet-shedding behavior, and we have understood how to tune the growth process to deliver stable droplet-shedding instead of flooding. The process uses inexpensive reagents, can operate below 100 °C via immersion in an aqueous bath, and takes 1-3 h to complete, making it readily scalable to areas of many square meters and complex geometries.

    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.

    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.

    An exceptional deposit covering an area of ∼7700 km2, displaying morphology indicative of an originally fluid material, occurs near 42.2°N, 167.4°E on the lunar farside. The material occurs as smooth, flat deposits (here termed "ponds") on the bottoms of many craters and in other topographic depressions, as well as a veneer across the majority of the region. Within this area, the ponded deposits and widespread-veneer have an estimated volume of ∼8 km3; the veneer constitutes the great majority of this volume. This material appears to have flowed downslope across the surface, collecting in flat-surface accumulations. The surfaces of the ponds and veneer are only lightly cratered, indicating a young (i.e., late Copernican) age. Four possible modes of origin are investigated: basin ejecta, pyroclastic volcanism, effusive volcanism, and ballistically emplaced impact-melt. Volcanism and basin ejecta appear to be inconsistent with the observed morphology: an implausible number of vents are required for volcanism and the morphological properties do not resemble basin ejecta. We suggest that ballistically emplaced impact melt is most consistent with the observations. Possible source craters for impact melt, based on minimum required size (>20 km diameter) and age, are at least 250 km distant and cannot be definitively tied to the pond deposits. This discovery places important new constraints on our knowledge of the distribution of impact melt relative to the parent crater.

    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.

    2004-08-01

    Baseline distortion-product otoacoustic emissions (DPOAEs) at several primary-tone levels were compared between naive 2- to 3-month old inbred CBA/CaJ (CBA) and wild-derived MOLF/Ei (MOLF) mice. Only minor DPOAE differences were noted between the two strains and these differences were not systematic across frequency or test levels. These emission findings were consistent with earlier results on auditory brainstem response thresholds reported by others [Zheng et al., Hear. Res. 130 (1999) 94-107] thus suggesting that both CBA and MOLF strains have normal hearing. Subsequent episodes of over-exposure to a 105-dB SPL, octave-band noise centered at 10 kHz for 8 h revealed that MOLF DPOAEs were exceptionally resistant to the adverse aftereffects of excessive noise exposure as compared to CBA mice. Unlike the noise-exposure resistant inbred 129/SvEvTac strain, which has reduced baseline DPOAE levels especially at high frequencies, MOLF mice have normal DPOAEs making the interpretation of noise-exposure effects more straightforward.

    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.

  2. Tropical Refuges with Exceptionally High Phylogenetic Diversity Reveal Contrasting Phylogenetic Structures

    Full Text Available Loss of phylogenetic diversity (PD has gained increasing attention in conservation biology. However, PD is not equally distributed in a phylogeny and can be better assessed when species relatedness (phylogenetic structure: PS is also considered. Here, we investigate PD and PS in two refuges of biodiversity in northeastern Brazil: the Bahia Costal Forest (BCF in the Atlantic Forest domain and Chapada Diamantina (CD in the Caatinga domain. We used geographic data of 205 species at two spatial scales and a chronogram of Apocynaceae based on matK sequences to estimate PD and PS. Our results show an exceptionally high PD in both refuges, overdispersed in BCF and clustered in CD, although this difference is less evident or absent for recent relationships, especially at a smaller spatial scale. Overall, PS suggests long-term competitive exclusion under climatic stability, currently balanced by habitat filtering, in BCF, and biome conservatism and limited dispersal leading to in situ diversification and high density of microendemics in CD. The phylogenetically clustered flora in CD, also threatened by climate changes, are naturally more vulnerable than BCF. Therefore, while in situ conservation may ensure protection of biodiversity in BCF, emergency ex situ conservation is strongly recommended in CD.

  3. Experimental observation of the topological structure of exceptional points in an ultrathin hybridized metamaterial

    2017-12-01

    The exceptional point (EP), which is one of the most important branch-type singularities exclusive to non-Hermitian systems, has been observed recently in various synthetic materials, giving rise to counterintuitive phenomena due to the nontrivial topology of the EP. Here, we present a direct experimental observation of the topological structure of the EPs via the angle-resolved transmission measurement of a hybridized metamaterial. Both eigenvalues and eigenvectors show branch-point singularities in the investigated biparametric space of frequency and incident angle. Importantly, the angle-resolved transmission coefficients provide all the information about the eigenvalues as well as the corresponding eigenvectors in the biparametric space, revealing the nontrivial topological structure of the EP, such as mode switching and the topological phase for a parameter loop encircling the EP. It is shown that the appearance of the EP in the scattering matrix is related directly to the perfect unidirectional transmission and the chirality of the EP corresponds to the maximum or minimum value of the asymmetric factor. Our investigation uncovers the capabilities of metamaterials for exploring the physics of EPs and their potential for having extreme optical properties, which provide potential applications in the spectral band ranging from microwaves to visible frequencies.

  4. 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.

    Full Text Available This paper presents the application of the model, MHYSER 1.0 (Model for the HYdraulics of SEdiments in Rivers, version 1.0, to study river morphological changes due to exceptional flooding. MHYSER 1.0 is a semi-two-dimensional model using the stream tubes concept to achieve lateral variations of velocity, flow stresses and sediment transport rate. Each stream tube has the same conveyance as the other ones. In MHYSER 1.0, the uncoupled approach is used to solve the set of conservation equations’. After the backwater calculation, the river is divided in a finite number of stream tubes of equal conveyances. The sediment routing and bed adjustments calculations are accomplished separately along each stream tube taking into account lateral mass exchanges. MHYSER 1.0 is applied to the Ha! Ha! River (Quebec, Canada, a tributary of the Saguenay River, for the 1996 “downpour“. The results show good correlation of with collected data. This application shows the capabilities of this model and predicts its promising role in solving complex real engineering cases.

    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.

    In this paper we define the analogue of Calabi-Yau geometry for generic D = 4, N = 2 flux backgrounds in type II supergravity and M-theory. We show that solutions of the Killing spinor equations are in one-to-one correspondence with integrable, globally defined structures in E{sub 7(7)} x R{sup +} generalised geometry. Such ''exceptional Calabi-Yau'' geometries are determined by two generalised objects that parametrise hyper- and vector-multiplet degrees of freedom and generalise conventional complex, symplectic and hyper-Kaehler geometries. The integrability conditions for both hyper- and vector-multiplet structures are given by the vanishing of moment maps for the ''generalised diffeomorphism group'' of diffeomorphisms combined with gauge transformations. We give a number of explicit examples and discuss the structure of the moduli spaces of solutions. We then extend our construction to D = 5 and D = 6 flux backgrounds preserving eight supercharges, where similar structures appear, and finally discuss the analogous structures in O(d, d) x R{sup +} generalised geometry.

    2013-12-01

    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-, Mg2+, K+ and Ca2+, 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.

    We present a formulation for achieving stable high-concentration (up to 20 mg/ml) aqueous dispersions of carbon nanotubes (CNTs) with exceptionally high microwave-frequency (0.5-6 GHz) dielectric properties. The formulation involves functionalizing CVD-synthesized CNTs via sonication in nitric and sulfuric acid. The overall chemical integrity of the CNTs is largely preserved, as demonstrated via physical and chemical characterizations, despite significant shortening and functionalization with oxygen-containing groups. This is attributed to the protected inner walls of double-walled CNTs in the samples. The resulting CNT dispersions show greatly enhanced dielectric properties compared to a CNT-free control. For example, at 3 GHz, the average relative permittivity and effective conductivity across several 20 mg/ml CNT samples were increased by ∼ 70% and ∼ 400%, respectively, compared to the control. These CNT dispersions exhibit the stability and extraordinary microwave properties desired in systemically administered theranostic agents for microwave diagnostic imaging and/or thermal therapy.

  10. Exceptional points of degeneracy and P T symmetry in photonic coupled chains of scatterers

    We demonstrate the existence of exceptional points of degeneracy (EPDs) of periodic eigenstates in non-Hermitian coupled chains of dipolar scatterers. Guided modes supported by these structures can exhibit an EPD in their dispersion diagram at which two or more Bloch eigenstates coalesce, in both their eigenvectors and eigenvalues. We show the emergence of a second-order modal EPD associated with the parity-time (P T ) symmetry condition, at which each particle pair in the double chain exhibits balanced gain and loss. Furthermore, we also demonstrate a fourth-order EPD occurring at the band edge. Such a degeneracy condition was previously referred to as a degenerate band edge in lossless anisotropic photonic crystals. Here, we rigorously show it under the occurrence of gain and loss balance for a discrete guiding system. We identify a more general regime of gain and loss balance showing that P T symmetry is not necessary to attain EPDs. Moreover, we investigate the degree of detuning of the EPD when the geometrical symmetry or balanced condition is broken. Furthermore, we demonstrate a realistic implementation of the EPD in a coupled chain made of pairs of plasmonic nanospheres and active core-shell nanospheres at optical frequencies. These findings open avenues toward superior light localization and transport with application to high-Q resonators utilized in sensors, filters, low-threshold switching and lasing.

    When the dimensionality of layered materials is reduced to the physical limit, an ultimate two-dimensional (2D) anisotropy and/or confinement effect may bring about extraordinary physical and chemical properties. Layered double hydroxides (LDHs), bearing abundant hydroxyl groups covalently bonded within 2D host layers, have been proposed as inorganic anion conductors. However, typical hydroxyl ion conductivities for bulk or lamellar LDHs, generally up to 10 -3 S cm -1 , are considered not high enough for practical applications. We show that single-layer LDH nanosheets exhibited exceptionally high in-plane conductivities approaching 10 -1 S cm -1 , which were the highest among anion conductors and comparable to proton conductivities in commercial proton exchange membranes (for example, Nafion). The in-plane conductivities were four to five orders of magnitude higher than the cross-plane or cross-membrane values of restacked LDH nanosheets. This 2D superionic transport characteristic might have great promises in a variety of applications including alkaline fuel cells and water electrolysis.

    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.

    The practice of medicine is a fruitful marriage of classic diagnostic and healing arts with modern advancements in many relevant sciences. The scientific aspects of medicine are rooted in understanding the biology of our species and those of other organisms that interact with us in health and disease. Thus, it is reasonable to paraphrase Dobzhansky, stating that, "nothing in the biological aspects of medicine makes sense except in the light of evolution." However, the art and science of medicine are also rooted in the unusual cognitive abilities of humans and the cultural evolutionary processes arising. This explains the rather bold and inclusive title of this essay. The near complete absence of evolution in medical school curricula is a historical anomaly that needs correction. Otherwise, we will continue to train generations of physicians who lack understanding of some fundamental principles that should guide both medical practice and research. I here recount my attempts to correct this deficiency at my own medical school and the lessons learned. I also attempt to summarize what I teach in the limited amount of time allowed for the purpose. Particular attention is given to the value of comparing human physiology and disease with those of other closely related species. There is a long way to go before the teaching of evolution can be placed in its rightful context within the medical curriculum. However, the trend is in the right direction. Let us aim for a day when an essay like this will no longer be relevant.

    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.

    Known viruses build their particles using a restricted number of redundant structural solutions. Here, we describe the Aeropyrum coil-shaped virus (ACV), of the hyperthermophilic archaeon Aeropyrum pernix, with a virion architecture not previously observed in the viral world. The nonenveloped, hollow, cylindrical virion is formed from a coiling fiber, which consists of two intertwining halves of a single circular nucleoprotein. The virus ACV is also exceptional for its genomic properties. It is the only virus with a single-stranded (ss) DNA genome among the known hyperthermophilic archaeal viruses. Moreover, the size of its circular genome, 24,893 nt, is double that of the largest known ssDNA genome, suggesting an efficient solution for keeping ssDNA intact at 90–95 °C, the optimal temperature range of A. pernix growth. The genome content of ACV is in line with its unique morphology and confirms that ACV is not closely related to any known virus. PMID:22826255

    We report, for the first time, a one-step hydrothermal (HT) process to design and synthesize water-dispersible chitosan nanoparticles loaded with mixed valence copper. Interestingly, this HT copper-chitosan biocompatible composite exhibits exceptionally high antimicrobial properties. A comprehensive characterization of the composite indicates that the hydrothermal process results in the formation of monodispersed nanoparticles with average size of 40 ± 10 nm. FT-IR and Raman spectroscopic studies unveiled that the hydrolysis of the glycoside bonds as the origin of the depolymerization of chitosan. Furthermore, X-Ray Photoelectron Spectroscopy measurements confirmed the presence of mixed valence copper states in the composite, while UV-Vis and FT-IR studies revealed the chemical interaction of copper with the chitosan matrix. Hence, the extensive spectroscopic data provide strong evidence that the chitosan structure was rearranged to capture copper oxide nanoparticles. Finally, HT copper-chitosan composite showed a complete killing effect when tested against both Gram negative ( E. coli) and Gram positive ( S. aureus) bacteria at metallic copper concentration of 100 μg/ml (1.57 mM). At the same concentration, neither pure chitosan nor copper elicited such antimicrobial efficacy. Thus, we show that HT process significantly enhances the synergistic antimicrobial effect of chitosan and copper in addition to increasing the water dispersibility.

    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.)

    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.

  19. The Problem with Violence: Exceptionality and Sovereignty in the New World

    Directory of Open Access Journals (Sweden)

    Deborah A. Thomas

    2013-09-01

    Full Text Available For many observers, the violent and often spectacular crime that takes place in particular Caribbean areas is evidence of a failure to create a growth-oriented economy and morally progressive ethos. It is a problem of culture, a mark of backwardness, an unsuccessful movement from savagery, or a failure to take advantage of post-World War II opportunities for development in political, economic, and socio-cultural fields. At the very least, it is something that marks the Caribbean—as well as some spaces within Latin America—as seeming to have taken a different path in relation to other New World trajectories. This article uses the case of Jamaica—itself often portrayed as exceptional within the region—to think through how, when, and why the US is, on one hand and from one perspective, written out of these narratives and, on the other and from alternative vantage points, central to them. In doing so, Thomas emphasizes the long-standing transnational dimension of violence in the postcolonial Americas, situating the New World as a single sphere of experience, in order to say something about the relationships among violence, the exploitation and settlement of the New World, sovereignty, and the various phases of modern capitalism.

    In this study, we focused on the exceptionally large mammals inhabiting the Americas during the Quaternary period and the paramount role of body size in species ecology. We evaluated two main features of Pleistocene food webs: the relationship between body size and (i) trophic position and (ii) vulnerability to predation. Despite the large range of species sizes, we found a hump-shaped relationship between trophic position and body size. We also found a negative trend in species vulnerability similar to that observed in modern faunas. The largest species lived near the boundary of energetic constraints, such that any shift in resource availability could drive these species to extinction. Our results reinforce several features of megafauna ecology: (i) the negative relationship between trophic position and body size implies that large-sized species were particularly vulnerable to changes in energetic support; (ii) living close to energetic imbalance could favour the incorporation of additional energy sources, for example, a transition from a herbivorous to a scavenging diet in the largest species (e.g. Megatherium) and (iii) the interactions and structure of Quaternary megafauna communities were shaped by similar forces to those shaping modern fauna communities. © 2016 The Author(s).

  1. Gender Differences in Academic Achievement: Is Writing an Exception to the Gender Similarities Hypothesis?

    The gender similarities hypothesis by J. S. Hyde ( 2005 ), based on large-scale reviews of studies, concludes that boys and girls are more alike than different on most psychological variables, including academic skills such as reading and math (J. S. Hyde, 2005 ). Writing is an academic skill that may be an exception. The authors investigated gender differences in academic achievement using a large, nationally stratified sample of children and adolescents ranging from ages 7-19 years (N = 2,027). Achievement data were from the conormed sample for the Kaufman intelligence and achievement tests. Multiple-indicator, multiple-cause, and multigroup mean and covariance structure models were used to test for mean differences. Girls had higher latent reading ability and higher scores on a test of math computation, but the effect sizes were consistent with the gender similarities hypothesis. Conversely, girls scored higher on spelling and written expression, with effect sizes inconsistent with the gender similarities hypothesis. The findings remained the same after controlling for cognitive ability. Girls outperform boys on tasks of writing.

    Piriformospora indica is a basidiomycete of the order Sebacinales, representing a model for the study of mutualistic symbiosis and, beyond that, the plant immune system. The fungus colonizes the roots of a wide range of vascular plants, increasing their growth, seed yield and adaptation to abiotic and biotic stresses. The fungal colonization of roots begins with a biotrophic growth phase, in which living cells are colonized, and continues with a cell death-dependent phase, in which root cells are actively killed by the fungus. The complexity of sebacinalean symbiosis is further enhanced by the presence of endocellular bacteria which may represent significant determinants for a successful outcome of the symbioses. Molecular ecological analyses have revealed an exceptional relevance of sebacinoid fungi in natural ecosystems worldwide. This natural competence could be rooted in their phenotypic adaptability, which, for instance, allows P. indica to grow readily on various synthetic media and to colonize distinct hosts. In molecular and genetic studies, P. indica's mutualistic colonization strategy has been partly unravelled, showing that the jasmonate pathway is exploited for immune suppression and successful development in roots. Research on P. indica supports efforts to make the bioprotective potential of the fungus accessible for agricultural plant production. The decoding of P. indica's genome has revealed its potential for application as bioagent and for targeted improvement of crop plants in biotechnology-based approaches. © 2011 THE AUTHORS.

    Full Text Available The purpose of our endeavour is to bring into the light of debates the situation that might exceptionally occur at the level of administrative territorial authority (ATU – villages, cities, municipalities and counties when it is affected the budgetary activity because the mayor/chairman of CC (County Council is unable to exert its mandate, the LC (Local County/CC is dissolved and the secretary position of the ATU is vacant. The discussion is focused on the legislative solution adopted by the Government through the Emergency Order, establishing the possibility according to which the prefect can name a person – by detachment – as secretary of the LC/CC. At the same time, it was also identified the solution for preventing a budgetary obstruction caused by the existence of the deliberative authority dissolution state which consists in the enactment of application in the current financial year of the ultimate budget, updated with the allocated amounts in the current year coming from the state budget or other budgets, respecting the monthly expenditures limit of 1/12 of this total budget.

    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.

    Non-Hermitian systems always play a negative role in wave manipulations due to inherent non-conservation of energy as well as loss of information. Recently, however, there has been a paradigm shift on utilizing non-Hermitian systems to implement varied miraculous wave controlling. For example, parity-time symmetric media with well-designed loss and gain are presented to create a nontrivial effect of unidirectional diffraction, which is observed near the exceptional points (EPs) in the non-Hermitian systems. Here, we report the design and realization of non-Hermitian acoustic metamaterial (NHAM) and show that by judiciously tailoring the inherent loss, the phase and amplitude of reflection can possibly be tuned in a decoupled manner. Such decoupled tuning of phase and amplitude is closely related to the EPs. As a demonstration of functionality, we experimentally generate a high-quality acoustic hologram via NHAM. Our work may open a new degree of freedom for realizing the complete control of sound.

    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.

    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.

    The angiosperm family Myrtaceae comprises 17 tribes with more than half of the estimated 5500 species being referred to the fleshy-fruited and predominantly rainforest associated Syzygieae and Myrteae. Previous studies suggest that fleshy fruits have evolved separately in these lineages, whereas generally shifts in fruit morphology have been variously implicated in diversification rate shifts among angiosperms. A phylogenetic hypothesis and estimate divergence times for Myrtaceae is developed as a basis to explore the evidence for, and drivers of, elevated diversification rates among the fleshy-fruited tribes of Myrtaceae. Bayesian phylogenetic analyses of plastid and nuclear DNA sequences were used to estimate intertribal relationships and lineage divergence times in Myrtaceae. Focusing on the fleshy-fruited tribes, a variety of statistical approaches were used to assess diversification rates and diversification rate shifts across the family. Analyses of the sequence data provide a strongly supported phylogenetic hypothesis for Myrtaceae. Relative to previous studies, substantially younger ages for many of the clades are reported, and it is argued that the use of flexible calibrations to incorporate fossil data provides more realistic divergence estimates than the use of errorless point calibrations. It is found that Syzygieae and Myrteae have experienced elevated diversification rates relative to other lineages of Myrtaceae. Positive shifts in diversification rate have occurred separately in each lineage, associated with a shift from dry to fleshy fruit. Fleshy fruits have evolved independently in Syzygieae and Myrteae, and this is accompanied by exceptional diversification rate shifts in both instances, suggesting that the evolution of fleshy fruits is a key innovation for rainforest Myrtaceae. Noting the scale dependency of this hypothesis, more complex explanations may be required to explain diversification rate shifts occurring within the fleshy

  9. Exceptional Evolutionary Expansion of Prefrontal Cortex in Great Apes and Humans.

    One of the enduring questions that has driven neuroscientific enquiry in the last century has been the nature of differences in the prefrontal cortex of humans versus other animals [1]. The prefrontal cortex has drawn particular interest due to its role in a range of evolutionarily specialized cognitive capacities such as language [2], imagination [3], and complex decision making [4]. Both cytoarchitectonic [5] and comparative neuroimaging [6] studies have converged on the conclusion that the proportion of prefrontal cortex in the human brain is greatly increased relative to that of other primates. However, considering the tremendous overall expansion of the neocortex in human evolution, it has proven difficult to ascertain whether this extent of prefrontal enlargement follows general allometric growth patterns, or whether it is exceptional [1]. Species' adherence to a common allometric relationship suggests conservation through phenotypic integration, while species' deviations point toward the occurrence of shifts in genetic and/or developmental mechanisms. Here we investigate prefrontal cortex scaling across anthropoid primates and find that great ape and human prefrontal cortex expansion are non-allometrically derived features of cortical organization. This result aligns with evidence for a developmental heterochronic shift in human prefrontal growth [7, 8], suggesting an association between neurodevelopmental changes and cortical organization on a macroevolutionary scale. The evolutionary origin of non-allometric prefrontal enlargement is estimated to lie at the root of great apes (∼19-15 mya), indicating that selection for changes in executive cognitive functions characterized both great ape and human cortical organization.

    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 A. It has a steep rise at wavelengths shorter than 3000 A, 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 H{alpha}/H{beta} 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{proportional_to}a {sup -1.4}, truncated at a maximum size of a{sub 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.

    Few co-morbidity studies have been conducted since the Leeds Consensus Statement on developmental co-ordination disorder (DCD) in 2006. In this Statement, international cut-offs and inclusion criteria were agreed and consequently, the status of DCD changed. Furthermore, most existing co-morbidity studies are small clinical studies, rather than epidemiological studies, resulting in a broad range of co-morbidity rates. DCD has a higher incidence for boys in comparison with girls; questions arise if this preponderance remains the same in combination with other developmental disorders. Therefore, in this study we aimed to determine co-morbidity and gender differences of motor problems in children with a pervasive developmental disorder, a hyperkinetic disorder and/or a speech, language or learning disability. Profiles of 3608 children (mean age: 9 years 1 month) referred to rehabilitation centres for behavioural, developmental and sensorineural disorders were studied. Motor problems were reported in one-fifth of the total sample. Co-morbidity of motor problems in specific disorders varied from almost one-fourth to more than one-third. The male/female ratio was significantly higher in children with motor problems and two or more other disorders, compared with children with motor problems and less than two other disorders. This study indicates that co-morbidity of motor problems with other clinical disorders is not exceptional and developmental deviance is seldom specific to one domain. However, current co-morbidity studies tend to overestimate the number of children with motor problems. In addition, there may be different patterns of symptoms between the genders. These findings stress the importance of assessing motor skills in children with various developmental disorders. © 2011 Blackwell Publishing Ltd.

    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.

  15. The offshore export of sand during exceptional discharge from California rivers

    Littoral cells along active tectonic margins receive large inputs of sand and gravel from coastal watersheds and commonly lose this sediment to submarine canyons. One hypothesis is that the majority of coarse (sand and gravel) river sediment discharge will be emplaced within and immediately “resupply” local littoral cells. A competing hypothesis is that the infrequent, large floods that supply the majority of littoral sediment may discharge water-sediment mixtures within negatively buoyant hyperpycnal plumes that transport sediment offshore of the littoral cell. Here we summarize pre- and post-flood surveys of two wave-dominated California (United States) river deltas during record to near-record floods to help evaluate these hypotheses: the 1982–1983 delta at the San Lorenzo River mouth and the 2005 delta at the Santa Clara River mouth. Flood sedimentation at both deltas resulted in several meters of aggradation and hundreds of meters of offshore displacement of isobaths. One substantial difference between these deltas was the thick (>2 m) aggradation of sand on the inner shelf of the Santa Clara River delta that contained substantial amounts (∼50%) of littoral-grade sediment. Once deposited on the inner shelf, only a fraction (∼20%) of this river sand was observed to migrate toward the beach over the following 5 yr. Furthermore, simple hypopycnal plume behavior could not explain deposition of this sand on the inner shelf. Thus, during an exceptional flood a substantial amount of littoral-grade sand was exported offshore of the littoral system at the Santa Clara River mouth—likely from hyperpycnal plume processes—and was deposited on the inner shelf.

    Trauma research has been limited by perceived patient reluctance to participate in exception from informed consent (EFIC) studies. We hypothesized that race, socioeconomic status, and proximity to violence influence willingness to participate in and perception of EFIC research among at-risk populations. Trauma patients, families, and community members ranked statements regarding attitude toward EFIC in the context of an upcoming trial and willingness to participate in emergency research using a 5-point Likert scale during a community consultation. Higher total scores reflected a more positive attitude regarding EFIC (range, 6-30; neutral, 18) and willingness (range, 23-115; neutral, 69). Subject zip code was used to calculate median income, as an estimate for socioeconomic status, and proximity to the five most violent city zip codes. Linear regression, Spearman's correlation, and Kruskal-Wallis tests (p attitudes toward EFIC. A total of 179 subjects participated including trauma patients (n = 99), families (n = 33), and community members (n = 47). Overall, participants were supportive of EFIC and reported high scores in willingness to participate (median, 24; interquartile range, 21-25; median 89, interquartile range, 82-95, respectively). Proximity to violence did correlate with race (p = 0.03) but was not associated with violent mechanism of injury, perception of EFIC, or willingness to participate in emergency research. Estimated socioeconomic status and race did not correlate with perception of or willingness to participate in EFIC. Based on our data, there is no correlation between either proximity to violence or estimated socioeconomic status and willingness to participate in EFIC research. Given this lack of correlation, researchers should partner with at-risk communities to conduct EFIC studies without concern for limited participation. Epidemiologic/prognostic study, level III.

    Background Intravenous delivery of volatile fluorinated anesthetics has a number of potential advantages when compared to the current inhalation method of administration. We reported previously that the IV delivery of sevoflurane can be achieved through an emulsion composed of a linear fluorinated diblock copolymer, a stabilizer, and the anesthetic. However, this original emulsion was subject to particle size growth that would limit its potential clinical utility. We hypothesized that the use of bulkier fluorous groups and smaller poly(ethylene glycol) moieties in the polymer design would result in improved emulsion stability while maintaining anesthetic functionality. Methods The authors prepared emulsions incorporating sevoflurane, perfluorooctyl bromide as a stabilizing agent, and combinations of linear fluorinated diblock copolymer and a novel dibranched fluorinated diblock copolymer. Emulsion stability was assessed using dynamic light scattering. The ability of the emulsions to induce anesthesia was tested in vivo by administering them intravenously to fifteen male Sprague-Dawley rats and measuring loss of the forepaw righting reflex. Results 20% (volume/volume) sevoflurane emulsions incorporating mixtures of dibranched- and linear diblock copolymers had improved stability, with those containing an excess of the dibranched polymers displaying stability of particle size for over one year. The ED50s for loss of forepaw righting reflex were all similar, and ranged between 0.55 and 0.60 ml/kg body weight. Conclusions Hemifluorinated dibranched polymers can be used to generate exceptionally stable sevoflurane nanoemulsions, as required of formulations intended for clinical use. Intravenous delivery of the emulsion in rats resulted in induction of anesthesia with rapid onset and smooth and rapid recovery. PMID:22354241

    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.

    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

    Exceptional experiences (EE) are experiences that deviate from ordinary experiences, for example precognition, supernatural appearances, or déjà vues. In spite of the high frequency of EE in the general population, little is known about their effect on mental health and about the way people cope with EE. This study aimed to assess the quality and quantity of EE in persons from the Swiss general population, to identify the predictors of their help-seeking, and to determine how many of them approach the mental health system. An on-line survey was used to evaluate a quota sample of 1580 persons representing the Swiss general population with respect to gender, age, and level of education. Multinomial logistic regression was applied to integrate help-seeking, self-reported mental disorder, and other variables in a statistical model designed to identify predictors of help-seeking in persons with EE. Almost all participants (91%) experienced at least one EE. Generally, help-seeking was more frequent when the EE were of negative valence. Help-seeking because of EE was less frequent in persons without a self-reported mental disorder (8.6%) than in persons with a disorder (35.1%) (OR = 5.7). Even when frequency and attributes of EE were controlled for, people without a disorder sought four times less often help because of EE than expected. Persons with a self-reported diagnosis of mental disorder preferred seeing a mental health professional. Multinomial regression revealed a preference for healers in women with less education, who described themselves as believing and also having had more impressive EE. Persons with EE who do not indicate a mental disorder less often sought help because of EE than persons who indicated a mental disorder. We attribute this imbalance to a high inhibition threshold to seek professional help. Moreover, especially less educated women did not approach the mental health care system as often as other persons with EE, but preferred seeing a

    In situ measurements with a four-channel stratospheric condensation particle counter (CPC) were conducted at up to 20 km altitude on board the aircraft M-55 Geophysica from Kiruna, Sweden, in January through March (EUPLEX 2003, RECONCILE 2010) and in December (ESSenCe 2011). During all campaigns air masses from the upper stratosphere and mesosphere were subsiding inside the Arctic winter vortex, thus initializing a transport of refractory aerosol into the lower stratosphere (Θ content of nitrous oxide (70 nmol mol-1 of N2O). This indicates that refractory aerosol originates from the upper stratosphere or the mesosphere. Derived from the mixing ratio of the simultaneously measured long-lived tracer N2O, an empirical index serves to differentiate probed air masses according to their origin: inside the vortex, the vortex edge region, or outside the vortex. Previously observed high fractions of refractory submicron aerosol in the 2003 Arctic vortex were ascribed to unusually strong subsidence during that winter. However, measurements under perturbed vortex conditions in 2010 and during early winter in December 2011 revealed similarly high values. Thus, the abundance of refractory aerosol in the lower stratosphere within the Arctic vortices appears to be a regular feature rather than the exception. During December, the import from aloft into the lower stratosphere appears to be developing; thereafter the abundance of refractory aerosol inside the vortex reaches its highest levels in March. The correlations of refractory aerosol with N2O suggest that, apart from mean subsidence, diabatic dispersion inside the vortex significantly contributes to the transport of particles to the Arctic lower stratosphere. A measurement-based estimate of the total mass of refractory aerosol inside the vortex is provided for each campaign. Based on the derived increase of particle mass in the lower stratospheric vortex (100-67 hPa pressure altitude) by a factor of 4.5 between early and

    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
