    Full Text Available Trata o presente ensaio, como objetivo principal, de aspectos relevantes da epopéia da evolução da Contabilidade, através das várias fases históricas de seu desenvolvimento, desde o estado de simples método de escrituração baseado nas partidas dobradas até sua maturação como ciência social aplicada de forte fundo econômico. Ao longo do trabalho são analisados os vários enfoques, abordagens e teorias, bem como circunstâncias históricas e outras que possam explicar a Contabilidade enquanto ciência genuinamente social. Na interpretação mais atualizada dessa disciplina, a cientificidade contábil deve ser procurada, preferencialmente, numa série de características como, por exemplo: no entendimento e mensuração aplicados aos elementos do patrimônio; na preponderância do valor econômico em lugar de simples custos ou preços; no caráter preditivo das demonstrações contábeis; na introdução do fator risco e do conceito do valor do dinheiro no tempo nas avaliações contábeis, bem como na consideração de custos imputados e de oportunidade etc. A Contabilidade pontifica pela observação das características anteriormente vistas e pela incorporação, em seu arcabouço conceitual, da premissa da prevalência da essência sobre a forma, no campo do conhecimento social aplicado, de natureza econômico-financeira, com ramificações nas áreas de produtividade, ambiental e social e com evidentes conotações quantitativas quanto à sua mecânica patrimonial. É claro que, para efeito de pesquisa e para realçar certas dimensões, a Contabilidade pode ser estudada sob as mais variadas ênfases, como a ética, a macroeconômica, a institucional e social, a comportamental, a sistêmica e a histórica, entre outras, só que a Contabilidade é muito mais que qualquer dessas suas abordagens individualmente tomadas.

    Full Text Available El resurgimiento de la discusión acerca de los modelos de desarrollo se puede ubicar hacia finales de la década de los noventa, cuando se hizo más que evidente que las medidas de ajuste ortodoxas aplicadas en América Latina en particular, no alcanzaron los resultados esperados, lo que generó dudas sobre la concepción y orientación que guiaron estos procesos. Hoy, en el marco de la crisis financiera global y del sistema capitalista en general, el tema vuelve a colocarse en el tapete. En este sentido, el presente artículo tiene como objetivo analizar el concepto de desarrollo desde las posiciones teóricas más relevantes en la segunda mitad del siglo XX y comienzos del XXI. La metodología utilizada para abordar el estudio fue la revisión y análisis teórico, el análisis de contenido y el análisis biblio-hemerográfico, previéndose un horizonte temporal entre 1960 y 2008, centrándose el análisis en los modelos operacionalizados en este periodo, además de incluir otros enfoques alternativos, dada su importancia teórica y epistémica. Los resultados evidencian que ha existido un marcado énfasis economicista alrededor de la idea de crecimiento económico como expresión de desarrollo, lo que ha motivado algunas respuestas desde otros ángulos. Se concluye en la necesidad de concebir el desarrollo como un proceso altamente complejo, que exige la integración de diversos factores que contribuyan a enriquecer el concepto e impacten las políticas y los actores involucrados en el mismo.

  17. Los cinco sexos, o cómo establecemos fronteras categoriales moralmente relevantes en un mundo difuso y continuo

    2013-08-01

    Full Text Available It is generally assumed that moral realism requires a determined world, so that moral judgments can also be determined. From this point of view, genuine moral dilemmas, where two alternative judgments are equally well-grounded, would be a counter-example for moral realism. In this paper I argue against such a challenge to moral realism. Starting from the continuous and gradualist character of the constitutive criteria of our concepts, I show how indeterminacies and limit cases are to be expected where it can be impossible to determine the truth value of a proposition. The existence of fuzzy conceptual boundaries does not mean they cannot be crossed (that they are not useful, that they do not capture difference or relevant features from the point of view of the causal structure of reality and its intelligibility, quite the opposite: they serve to establish morally relevant differences. The very possibility of a community with common conceptual practices depends upon the existence of paradigmatic, central cases that exemplify a concept meaning or a moral valuation.Generalmente se considera que el realismo moral exige un mundo bien determinado, para que las valoraciones también puedan estarlo. Desde este punto de vista, los dilemas morales genuinos, donde no pueda establecerse la opción moralmente correcta porque haya razones igualmente poderosas para ambas alternativas, constituyen un desafío al realismo moral. En este trabajo argumento en contra de este tipo de ataque al realismo moral. Partiendo del carácter continuo y gradual de los criterios constitutivos de nuestros conceptos, muestro cómo cabe esperar precisamente casos límite, en los que aparentemente está indeterminada la verdad. Que existan fronteras conceptuales borrosas no significa que no puedan ser cruzadas (que no sean útiles, que no capten diferencias o aspectos relevantes desde el punto de vista de la estructura causal de la realidad y su inteligibilidad, al contrario

    In order to do justice to the principle laid down in the Waste Management Technical Code that wastes disposed of underground in salt rock formations should remain clear of the biosphere for an indefinite time and without the need for later remedial measures and in order to realise the concept of so-called pollution-free disposal (mainly in non-saline formations) it is necessary to have verified knowledge on the types of waste concerned, the geological and hydrogeological conditions at the disposal site and in its surroundings, and on the future development of the entire disposal system. The long-term safety of a disposal site (or that of any kind of underground disposal of materials) depends on whether water or aqueous solutions can act on the host rock or on the wastes deposited in it, the extent to which this can result in dissolving processes and/or contaminant mobilisation and, finally, on whether this can conceivably lead to an impairment of the intended barriers and to a disposal of contaminants in the nearer or farther surroundings of the underground disposal site. This means in particular that the wastes themselves and their reactivity with fluid components in geological systems must be well-known or else examined and duly assessed. The following final report therefore is intended as a contribution to creating the requisite database for types of waste relevant to underground disposal. It has been possible here to collect important information on arising waste quantities and critical waste constituents and assess their hazard potential and so provide a basis for further research and development work.

    2006-10-01

    The purpose of our paper is to discuss basis selection for Knyazev's locally optimal block preconditioned conjugate gradient (LOBPCG) method. An inappropriate choice of basis can lead to ill-conditioned Gram matrices in the Rayleigh-Ritz analysis that can delay convergence or produce inaccurate eigenpairs. We demonstrate that the choice of basis is not merely related to computing in finite precision arithmetic. We propose a representation that maintains orthogonality of the basis vectors and so has excellent numerical properties.

  7. Safety Basis Report

    International Nuclear Information System (INIS)

    As part of the internal Integrated Safety Management Assessment verification process, it was determined that there was a lack of documentation that summarizes the safety basis of the current Yucca Mountain Project (YMP) site characterization activities. It was noted that a safety basis would make it possible to establish a technically justifiable graded approach to the implementation of the requirements identified in the Standards/Requirements Identification Document. The Standards/Requirements Identification Documents commit a facility to compliance with specific requirements and, together with the hazard baseline documentation, provide a technical basis for ensuring that the public and workers are protected. This Safety Basis Report has been developed to establish and document the safety basis of the current site characterization activities, establish and document the hazard baseline, and provide the technical basis for identifying structures, systems, and components (SSCs) that perform functions necessary to protect the public, the worker, and the environment from hazards unique to the YMP site characterization activities. This technical basis for identifying SSCs serves as a grading process for the implementation of programs such as Conduct of Operations (DOE Order 5480.19) and the Suspect/Counterfeit Items Program. In addition, this report provides a consolidated summary of the hazards analyses processes developed to support the design, construction, and operation of the YMP site characterization facilities and, therefore, provides a tool for evaluating the safety impacts of changes to the design and operation of the YMP site characterization activities

    In theoretical physics, theoretical chemistry and engineering, one often wishes to solve partial differential equations subject to a set of boundary conditions. This gives rise to eigenvalue problems of which some solutions may be very difficult to find. For example, the problem of finding...... such problems can be much reduced by making use of symmetry-adapted basis functions. The conventional method for generating symmetry-adapted basis sets is through the application of group theory, but this can be difficult. This book describes an easier method for generating symmetry-adapted basis sets...

  9. Basis Tensor Gauge Theory

    CERN Document Server

    Chung, Daniel J H

    2016-01-01

    We reformulate gauge theories in analogy with the vierbein formalism of general relativity. More specifically, we reformulate gauge theories such that their gauge dynamical degrees of freedom are local fields that transform linearly under the dual representation of the charged matter field. These local fields, which naively have the interpretation of non-local operators similar to Wilson lines, satisfy constraint equations. A set of basis tensor fields are used to solve these constraint equations, and their field theory is constructed. A new local symmetry in terms of the basis tensor fields is used to make this field theory local and maintain a Hamiltonian that is bounded from below. The field theory of the basis tensor fields is what we call the basis tensor gauge theory.

  10. Assessment of the failure behavior of dangerous goods containers made of high density polyethylene using relevant material parameters; Beurteilung des Versagensverhaltens von Gefahrengutbehaeltern aus Polyethylen hoher Dichte auf Basis relevanter Werkstoffkennwerte

    Energy Technology Data Exchange (ETDEWEB)

    Menrad, Andreas

    2013-09-01

    To obtain approval as dangerous goods packaging, different experimental tests are required to show the eligibility for the transportation of those goods. The data obtained from the material test performed on the pressed plates is not used to get absolute values for the failure time in an internal pressure test or the medium drop height. The goal is to see if there are changes in the behavior because a different HDPE is being used. All the jerrycans and pressed plates were specially made of four different materials to gain knowledge about the material properties. The plates and jerrycans were made of resin from the same batch to prevent variations caused by batch differences. The wall thickness is decisive and, therefore packagings were analyzed using computer tomography and the fringe projection technique. The results were compared to the magnetostatic measurement technique. The deformation under internal pressure was measured by digital image correlation. Deformations in the radial direction and the equivalent strains were determined. These deformations, strains, and their acceleration due to the swelling effect could be reproduced in the finite element analysis by using the temperature in the material model. The resistance against both internal pressure and absorption depend on the density of the material. Conditioning at elevated temperatures causes post crystallization and reduces internal stresses. Differences in the densities of the materials can be determined by using plates manufactured by compression molding. A higher density leads to a better performance under internal pressure. A correlation could be proved between the medium failure drop height (50 % of the packagings fail because of a crack) and the tensile impact strength of notched specimens cut out of the jerrycans side walls and the notched impact strength (NIS) of pressed plates. A higher NIS leads to a higher medium failure drop height. A low resistance against oxidative degradation will reduce the medium failure drop height drastically. However, materials which are highly resistant to oxidative degradation do not have lower medium failure drop heights after conditioning with nitric acid when compared to non-conditioned jerrycans. The resistance against oxidative degradation can be determined with plates manufactured by compression molding and allow conclusions about changes in medium drop heights.

A partir dos resultados da pesquisa, são apresentadas recomendações para que os gerentes foquem sua atenção e recursos nos fatores relevantes ao êxito e procedam de forma a minimizar o risco de fracasso. Questionários foram enviados pelo correio a gerentes e diretores de auditoria interna de 586 empresas de manufatura selecionadas aleatoriamente. Obteve-se uma amostra de 135 questionários, representando uma taxa de resposta de 22 por cento. De modo geral, as empresas não estão enfatizando algumas das mais importantes atividades e tarefas recomendadas na literatura de reengenharia, tais como mudança para processos de negócio orientados para o mercado, o elemento que adiciona valor a cada atividade de negócios e aplicação da inovação tecnológica adequada. Baseado nos resultados, recomenda-se à alta administração que não se engaje em projetos de reengenharia antes de ter assegurado a presença dos fatores de êxito considerados relevantes na pesquisa. Embora os resultados sejam baseados em empresas de manufatura, os mesmos podem ser generalizados para outros setores.

O processo de tomada de decisões financeiras exige o conhecimento de valores econômicos adequados, o que se torna cada vez mais demandado pelos usuários da Contabilidade. Este trabalho, portanto, buscou aferir a compreensão de alguns termos explorados no contexto da disciplina Teoria da Contabilidade, tais como ativos, passivos, goodwill, receitas, despesas, ganhos e perdas. Examinou-se uma amostra composta por 591 alunos matriculados em cursos de Ciências Contábeis que já haviam frequentado a disciplina Teoria da Contabilidade em instituições de ensino superior localizadas na cidade de Salvador (BA. A análise dos resultados por meio de uma regressão logística indica que a relação desempenho do discente e titulação do docente é mais significativa que a relação desempenho do discente e tipo da IES, contudo, de forma geral, conceitos superficiais sobre os tópicos tratados nesse trabalho foram citados em todos os níveis. Os resultados evidenciaram, em geral, falhas na compreensão de conceitos contábeis relevantes para a formação do aluno, refletindo majoritariamente uma visão superada ou, no mínimo, conservadora. Quando comparados por tipo de instituição de ensino, os resultados indicam que estudantes de instituições públicas possuem melhor domínio dos conceitos considerados neste estudo. A compreensão melhora um pouco mais quando a titulação do docente evolui de especialista para mestre e deste para doutor.

OBJETIVOS: Analisar os aspectos relevantes na emissão dos diagnósticos de DORT e Fibromialgia na percepção de médicos assistenciais e peritos. MÉTODOS: Neste estudo, 75 médicos (36 assistenciais e 39 peritos responderam a questões estruturadas e abertas sobre aspectos considerados relevantes na emissão de diagnóstico destas síndromes. RESULTADOS: As respostas dos dois grupos foram correlacionadas pelo teste de Spearman (α=0,05 e submetidos ao método de Discurso do Sujeito Coletivo (DSC. Os médicos assistenciais tenderam a valorizar o fator "quadro clínico e tempo de evolução", enquanto os médicos peritos tenderam a apontar "história ocupacional" na definição do diagnóstico de LER/DORT. Já para o diagnóstico de Fibromialgia, os peritos tenderam a apontar o fator "quantidade de tender points", enquanto os médicos assistenciais indicaram mais frequentemente "característica da dor". Apesar dessas discretas discrepâncias, alta correlação (r=0,85, ρ=0,01 foi identificada entre os grupos quando apontaram aspectos comuns e distintos no estabelecimento do diagnóstico para as duas síndromes. Os relatos também enfatizaram a necessidade da investigação de riscos presentes no trabalho para a definição de um diagnóstico mais preciso. CONCLUSÕES: Nesse sentido, objetivando uniformizar condutas avaliativas, preventivas e terapêuticas para médicos, fisioterapeutas e demais profissionais envolvidos no atendimento dessas síndromes, seria recomendável maior divulgação dos critérios utilizados por entidades internacionais no diagnóstico da Fibromialgia e a inclusão de treinamento para identifica

    The laser is a well established surgical instrument in lung therapy. This report provides information on the biophysical basics of the laser-induced thermotherapy (LITT) of lung metastases. Optical properties like absorption and scattering determine the penetration depth of laser radiation in tissue. These parameters vary dynamically during the application and define in combination with thermal tissue properties the achievable destruction volume. Parenchyma behaves very differently compared to more dense tissues due to local inhomogenities and the large amount cavaties filled with air. Beside an account of the affecting parameters an overview of therapy options is given. Therapeutic results depend not only on the tissue properties but also on the technical equipment, e.g. the applicator design and the energy applied. Complex dosimetric models allow for a calculation of the lesion's size in advance. (orig.) [German] Der Laser ist in der Lungenchirurgie ein bereits etabliertes Instrument. In diesem Beitrag werden speziell die biophysikalischen Hintergruende der laserinduzierten Thermotherapie (LITT) von Lungenmetastasen beschrieben. In der Gewebeoptik determinieren Absorption und Streuung die Eindringtiefe von Laserlicht. Diese Parameter veraendern sich dynamisch waehrend der Anwendung und bestimmen in Verbindung mit den thermischen Gewebeeigenschaften die maximal erzielbaren Destruktionsvolumina. Lokale Inhomogenitaeten und der hohe Anteil luftgefuellter Hohlraeume unterscheiden das Parenchym in dieser Hinsicht signifikant von dichteren Geweben. Neben einer Darstellung der beeinflussenden Parameter wird ein Ueberblick ueber die Therapieoptionen gegeben. Der Therapieerfolg haengt neben den genannten gewebeseitigen Parametern von Anzahl und Geometrie der Applikatoren und der applizierten Energie ab und kann mit komplexen Dosimetriemodellen im voraus kalkuliert werden.

  8. Theoretical basis for QCD cascade

    International Nuclear Information System (INIS)

    The systematic analysis of Collinear and Infra-red singularities of perturbative QCD led to the discovery of jets in hard processes and to the possibility of describing the asymptotic parton emission by a Monte Carlo simulation. This paper summarizes results of perturbative analysis which are the basis of the M.C. method. In particular it stresses the importance of the recent results on IR analysis both in the soft (x→o) and hard (x→l) region. Also discussed are the relevance of subasymptotic corrections and are the features of preconfinement which is the basis of a phenomenological model for hadronization

  9. Flavor Democracy: On which basis?

    CERN Document Server

    Rador, T

    2003-01-01

    I argue that flavor democracy should not be considered as a "mere" assumption, but rather a fact that is inherent where there is hierarchy of quark masses. Briefly the crux of the argument is the ambiguity of defining a basis when one introduces a mass matrix. That is there is a degree of freedom of also defining a basis other than the weak eigenbasis with respect to which one can write down mass matrices. Since the ultimate aim is to diagonalize to the mass eigenbasis this is physically equivalent. But not necessarily so for the human eye.

  10. BWR NSSS design basis documentation

    International Nuclear Information System (INIS)

    In 1985 an incident at Toledo Edison's Davis Besse plant caused the U.S. Nuclear Regulatory Commission (NRC) to re-evaluate the technical information that the utilities had readily available to support the design of their plants. The Design Basis programs, currently on going in most U.S. utilities, have been the nuclear industry's response to the needs identified by this re-evaluation. In order to understand the Design Basis programs which have been implemented by the U.S. nuclear utilities, it is necessary to understand the problem as it was perceived by the nuclear industry (the utilities, the original NSSS designers and the regulators) after the Davis-Besse incident, the subsequent programs undertaken by the industry under the leadership of INPO and NUMARC, the NRC's actions, and the overall evolution of the industry's vision in relation to this problem. This paper presents the history of the design basis efforts from the first recognition of the problem by the NRC after the Davis-Besse incident, describes the actions taken by the NRC, INPO, NUMARC, the U.S. utilities and the NSSS designers, and brings the problem statement up-to-date in relation to the vision presently held by the U.S. nuclear industry. It then presents a technical discussion to develop a detailed definition of design basis information to support the problem statement. The information originally supplied by the NSSS designers during the plant design and construction is discussed as well as its relationship to the previously defined design basis information. This section of the paper concludes by defining the additional information needed by nuclear utilities to satisfy the requirements developed from the problem statement. Having developed a definition of the additional information (i.e., information not originally supplied during design and construction) required to solve the design basis problem as it is presently perceived by the U.S. nuclear industry, the paper then discusses design basis

Impactos do aumento da temperatura são estudados através de cenários, que podem modificar o balanço hídrico em algumas regiões, tendo sido observado um aumento da ordem de 0,78ºC no período de 1917 a 2003, na região de Piracicaba. Para a região amazônica, foi observado um aumento de 0,56ºC durante o século XX. Tanto o desmatamento quanto as Mudanças Climáticas Globais atuam na direção de um aumento da temperatura, enquanto o desmatamento influi na direção de uma diminuição das precipitações. O desmatamento provoca, ainda, uma grande perda de biodiversidade, sendo estimadas em uma perda entre 8.000 até 34.000 espécies, considerando-se que o desmatamento aumenta em 1% ao ano.THIS PAPER indicates the environmental issues that must necessarily be approached, in Brazil, in a near future (2022. A study was made on some aspects of the effects of deforestation and Global Climate Change. A temperature rise around 0,78% has been observed during period of 1917 and 2003 in the Piracicaba region. For the Amazon region a rise of 0,56% was observed the 20th Century. The existing information indicates that not only deforestation but also Global Climate Changes act upon temperature rise. Deforestation has direct influence in precipitation decrease. The consequences of Global Climate Change are still unknown, being that some models indicate a precipitation rise and others a decrease. Deforestation also provokes great biodiversity loss, estimated between 8.000 to 34.000 species, considering that deforestation raises 1% per year.

    MOND is a phenomenological theory with no apparent physical justification which seems to undermine some of the basic principles that underpin established theoretical physics. It is nevertheless remarkably successful over its sphere of application and this suggests MOND may have some physical basis. It is shown here that two simple axioms pertaining to fundamental principles will reproduce the characteristic behaviour of MOND, though the axioms are in conflict with general relativistic cosmology.

Diverse systems in motion shift between two states depending on interactions that turnover at the rate of an applied cycle of force. Although one phase of the force cycle terminates the decay of the most recent state, continuation of the cycle of force regenerates the original decay process in a recursive cycle. By completing a cycle, kinetic energy is transformed into probability of sustaining ...

    1981-01-01

    This paper is a case study in attempting to apply a particular value (caring) to the domain of social policy, specifically resource conservation policy. The argument is that our consumer society erodes the social basis for the development by individuals of a sense of well-being and personal identity, and that a conservation ethic based on the concept of caring could provide a foundation in practical morality and public policy for a viable sense of well-being. Conservation, then, goes beyond eliminating wasteful consumption to encompass a public commitment that can further economic and social goals. 11 references.

    2012-01-01

    Full Text Available Así como la concepción del riesgo y su terminología han variado en el tiempo, la perspectiva disciplinar de su abordaje también ha cambiado. Enfoques derivados de las ciencias naturales, aplicadas y sociales no permiten aún generar una teoría consistente y coherente del riesgo, difi cultando una gestión efectiva que facilite su estimación e intervención desde una perspectiva multidisciplinar. Asimismo, el riesgo no puede considerarse solamente de forma objetiva cuando se busca su reducción dada las múltiples interpretaciones y perspectivas de los distintos actores sociales que confl uyen. La percepción social del riesgo se presenta como uno de los factores relevantes en el ámbito de los riesgos naturales, pues permite incorporar estas subjetividades pudiendo encontrar soluciones más realistas a los desastres. El presente trabajo evalúa esta componente para la ciudad de La Serena, IV Región de Coquimbo, mediante su relación con el nivel socioeconómico, factores de autoprotección y capacidad de autogestión, respecto de la amenaza de tsunami propiciada por la sismicidad en un país como Chile, considerado mundialmente el más sísmico del mundo, al ubicarse en la zona de subducción y deslizamiento de las Placas de Nazca y Sudamericana. Se observa una clara segregación de los estratos socioeconómicos, en los distritos La Compañía Alta e Intendencia, encontrando zonas con mayor vulnerabilidad. Los resultados indican que la percepción de riesgo está relacionada con aspectos sociales, corroborando entonces el carácter social que posee el riesgo.

    María Elinor Dulzaides Iglesias

    Full Text Available Competence is today a relevant conception to take into consideration. It implies more integration between strategy, study system, work and organizational culture, along with information management and knowledge. It offers potential to people and their development. The management of roles by competences is focused in development; it looks for what people are capable of doing in the future. Present day scenarios demand for a new educative arquitecture following learning for life, what implies: teaching to learn and, overall, to use information in an adequate manner. In this work we lay stress on the topic as an essential element to consider in Higher Medical Education, given the constant changes in medicine and the need for knowledge and skills for an adequate practice.

La gestión del desempeño por competencias se enfoca en esencia hacia el desarrollo, busca lo que las personas sean capaces de hacer en el futuro. Los escenarios actuales demandan una nueva arquitectura educativa que apunte al aprendizaje de por vida, lo que implica: enseñar a aprender y sobre todo utilizar adecuadamente la información. En este trabajo se enfatiza en el tema como elemento indispensable a considerar en la Educación Médica Superior, dado a los cambios constantes de la medicina y la necesidad de conocimientos y habilidades para una adecuada práctica.

  7. Quadratic Hedging of Basis Risk

    Directory of Open Access Journals (Sweden)

    Hardy Hulley

    2015-02-01

    Full Text Available This paper examines a simple basis risk model based on correlated geometric Brownian motions. We apply quadratic criteria to minimize basis risk and hedge in an optimal manner. Initially, we derive the Föllmer–Schweizer decomposition for a European claim. This allows pricing and hedging under the minimal martingale measure, corresponding to the local risk-minimizing strategy. Furthermore, since the mean-variance tradeoff process is deterministic in our setup, the minimal martingale- and variance-optimal martingale measures coincide. Consequently, the mean-variance optimal strategy is easily constructed. Simple pricing and hedging formulae for put and call options are derived in terms of the Black–Scholes formula. Due to market incompleteness, these formulae depend on the drift parameters of the processes. By making a further equilibrium assumption, we derive an approximate hedging formula, which does not require knowledge of these parameters. The hedging strategies are tested using Monte Carlo experiments, and are compared with results achieved using a utility maximization approach.

  11. Chemical basis for minimal cognition.

    Hanczyc, Martin M; Ikegami, Takashi

    2010-01-01

    We have developed a simple chemical system capable of self-movement in order to study the physicochemical origins of movement. We propose how this system may be useful in the study of minimal perception and cognition. The system consists simply of an oil droplet in an aqueous environment. A chemical reaction within the oil droplet induces an instability, the symmetry of the oil droplet breaks, and the droplet begins to move through the aqueous phase. The complement of physical phenomena that is then generated indicates the presence of feedback cycles that, as will be argued, form the basis for self-regulation, homeostasis, and perhaps an extended form of autopoiesis. We discuss the result that simple chemical systems are capable of sensory-motor coupling and possess a homeodynamic state from which cognitive processes may emerge. PMID:20586578

    Full Text Available Cardiac tumors are rare, and of these, primary cardiac tumors are even rarer. Metastatic cardiac tumors are about 100 times more common than the primary tumors. About 90% of primary cardiac tumors are benign, and of these the most common are cardiac myxomas. Approximately 12% of primary cardiac tumors are completely asymptomatic while others present with one or more signs and symptoms of the classical triad of hemodynamic changes due to intracardiac obstruction, embolism and nonspecific constitutional symptoms. Echocardiography is highly sensitive and specific in detecting cardiac tumors. Other helpful investigations are chest X-rays, magnetic resonance imaging and computerized tomography scan. Surgical excision is the treatment of choice for primary cardiac tumors and is usually associated with a good prognosis. This review article will focus on the general features of benign cardiac tumors with an emphasis on cardiac myxomas and their molecular basis.

    Full Text Available A municipalização do trânsito no Brasil, a partir do final da década de 1990, transformou o município em um importante agente social no cenário contemporâneo da educação no trânsito. A expansão das receitas dos órgãos executivos de trânsito coloca em pauta novos desafios de atuação do município, exigindo maior profissionalismo na aplicação dos recursos arrecadados, num contexto social que espera que os municípios produzam e transpareçam resultados efetivos de suas ações. Diante desta realidade, a possibilidade de se identificarem os fatores capazes de traduzir a complexa problemática de aplicação dos recursos arrecadados dos órgãos executivos de trânsito não é uma tarefa simples. A maioria das iniciativas para isso acaba falhando, principalmente pela multiplicidade de aspectos a serem considerados na abordagem do problema. Muitas vezes são omitidos ou desprezados os aspectos que deveriam ser contemplados, resultando em simplificações que acabam por produzir estruturas de avaliação incapazes de representar a realidade do processo. O presente estudo propõe-se a identificar os fatores relevantes na tomada de decisão para aplicação dos recursos arrecadados com multas de trânsito, a partir das visões dos diversos especialistas de trânsito e dos gestores de órgãos executivos de trânsito das capitais brasileiras. A identificação desses fatores foi possível a partir da utilização da Técnica Delphi, a qual foi realizada através de sete rodadas de entrevistas com 12 especialistas e aplicação de um questionário junto aos gestores de 10 das maiores capitais do pais. O produto final da pesquisa foi a construção da estrutura hierárquica desses fatores e suas respectivas dimensões.

    Tank Characterization Technical Sampling Basis (this document) is the first step of an in place working process to plan characterization activities in an optimal manner. This document will be used to develop the revision of the Waste Information Requirements Document (WIRD) (Winkelman et al. 1997) and ultimately, to create sampling schedules. The revised WIRD will define all Characterization Project activities over the course of subsequent fiscal years 1999 through 2002. This document establishes priorities for sampling and characterization activities conducted under the Tank Waste Remediation System (TWRS) Tank Waste Characterization Project. The Tank Waste Characterization Project is designed to provide all TWRS programs with information describing the physical, chemical, and radiological properties of the contents of waste storage tanks at the Hanford Site. These tanks contain radioactive waste generated from the production of nuclear weapons materials at the Hanford Site. The waste composition varies from tank to tank because of the large number of chemical processes that were used when producing nuclear weapons materials over the years and because the wastes were mixed during efforts to better use tank storage space. The Tank Waste Characterization Project mission is to provide information and waste sample material necessary for TWRS to define and maintain safe interim storage and to process waste fractions into stable forms for ultimate disposal. This document integrates the information needed to address safety issues, regulatory requirements, and retrieval, treatment, and immobilization requirements. Characterization sampling to support tank farm operational needs is also discussed.

  19. Molecular basis for color vision.

    Yoshizawa, T

    1994-05-01

    Amino acid sequences of four kinds of chicken cone pigments and two kinds of nocturnal gecko visual pigment were determined. Calculations of amino acid identities indicate that gecko pigments should be cone pigments. A phylogenetic tree of visual pigments constructed demonstrated that cone pigments evolved earlier than rod pigments (rhodopsins), indicating that daylight vision including color vision appeared earlier than twilight vision. The divergence of cone pigments to rhodopsins would be caused by replacing basic amino acid residues to acidic ones according to net charge calculations. A comparison between chicken rhodopsin and cone pigments (chicken green and red) displayed that the cone pigments are faster in regeneration from 11-cis retinal and opsin, faster in formation of meta II-intermediate and shorter in lifetime of meta II-intermediate than rhodopsin. These facts would partly explain the rapid dark adaptation, the rapid light response and the low photosensitivity of cones compared with rods. In comparison with di- and tri-chromatic color visions, chicken tetra-chromatic vision was discussed on the basis of both absorption spectra of cone pigments and filtering effect of oil droplets.

    2011-09-01

    Full Text Available Background and Objectives: Numerous opinions and medico-legal controversies have arisen up to the date from community treatment orders in Western countries, but underlying bioethical questions have not been specifically studied. The aim of this work is to contribute to further clarify the bioethical conflicts arising from community treatment orders. Methods: The bioethical deliberation of the author is principally based on what can be considered the deontologist-principlist dominant paradigm. These principles, as first described by Beauchamp and Childress in 1979, will be applied in this work to the actual situation of involuntary outpatient treatment. Results: The author's deliberation considers that community treatment orders are consistent first with the deontologist-principlist dominant paradigm of practical reason, respecting its four general categories of basic principles. It also respects the principles of the medical ethics of virtue, subsumed in the personalism of ontological matrix, in the same way as its ethos affects the intrinsic purpose which is the dignity of the person; and with the consequentialist utilitarianism because it seeks the proportionality of the common good. A community treatment order prescription must ultimately be based on a bioethical exercise of responsibility by the clinician, judiciously weighing up the classic principal prima facie duties which must necessarily be translated into a real duty referring to a specific patient and context. Conclusions: Community treatment orders are seen as a method of therapeutic intervention with a bioethical basis resistant to criticism.

    Procedural memory is acquired by trial and error. Our daily life is supported by a number of procedural memories such as those for riding bicycle, typing, reading words, etc. Procedural memory is divided into 3 types; motor, perceptual, and cognitive. Here, the author reviews the cognitive and neural basis of procedural memory according to these 3 types. It is reported that the basal ganglia or cerebellum dysfunction causes deficits in procedural memory. Compared with age-matched healthy participants, patients with Parkinson disease (PD), Huntington disease (HD) or spinocerebellar degeneration (SCD) show deterioration in improvements in motor-type procedural memory tasks. Previous neuroimaging studies have reported that motor-type procedural memory may be supported by multiple brain regions, including the frontal and parietal regions as well as the basal ganglia (cerebellum); this was found with a serial reaction time task (SRT task). Although 2 other types of procedural memory are also maintained by multiple brain regions, the related cerebral areas depend on the type of memory. For example, it was suggested that acquisition of the perceptual type of procedural memory (e.g., ability to read mirror images of words) might be maintained by the bilateral fusiform region, while the acquisition of cognitive procedural memory might be supported by the frontal, parietal, or cerebellar regions as well as the basal ganglia. In the future, we need to cleary understand the neural "network" related to the procedural memory. PMID:18646622

    Full Text Available Learning theory basis of andragogy. A cursory glance at andragogy creates the impression that humanistic learning theory plays an all encompassing role in the learner centered approach andragogy espouses. A closer look, however, reveals that Knowles (1973, after having made an intensive study of learning theory, created an extensive framework within which human resource development can take place. The fact that Knowles attracted critique from different areas, led to a need to ascertain the role different learning theories, if any, played in the emergence of andragogy. Having looked at the assumptions displayed by the andragogical approach, as well as a comparison of different learning theories and their connection with andragogy, it became clear that andragogy contains elements of various learning theories in an adapted way. These adaptations resulted in an approach to adult education in which learners are given the opportunity to be part of the learning process in such a way that they themselves contribute to the development which takes place. Opsomming Met 'n eerste oogopslag wil dit voorkom asof humanistiese leerteorie 'n oorheersende rol in die leerdergesentreerde benadering van andragogie speel. By nadere ondersoek blyk dit egter dat Knowles (1973, na 'n deeglike studie van verskillende leerteoretiese beginsels, 'n omvangryke raamwerk geskep het waarbinne, aan die hand van verskeie aangepaste leerteoretiese beginsels, menslike hulpbronontwikkeling kan plaasvind. As gevolg van die feit dat Knowles vanuit verskillende oorde kritiek op die lyf geloop het, is besluit om die rol wat verskillende leerteorieë in andragogie speel, te bestudeer. Dit blyk dat andragogie nie net elemente van verskillende leerteorieë bevat nie, maar dat toepaslike aspekte van die teoriee wat ondersoek is, benut en aangepas is om 'n geintegreerde benadering te bewerkstellig waarin veral volwassene-leerders by leergeleenthede en hulle selfontwikkeling betrek word.

We assess the performance of a number of approaches for obtaining CCSD correlation energies close to the complete basis-set limit in conjunction with relatively small DZ and TZ basis sets. These include global and system-dependent extrapolations based on the A + B/L{sup α} two-point extrapolation formula, and the well-known additivity approach that uses an MP2-based basis-set-correction term. We show that the basis set convergence rate can change dramatically between different systems(e.g.it is slower for molecules with polar bonds and/or second-row elements). The system-dependent basis-set extrapolation scheme, in which unique basis-set extrapolation exponents for each system are obtained from lower-cost MP2 calculations, significantly accelerates the basis-set convergence relative to the global extrapolations. Nevertheless, we find that the simple MP2-based basis-set additivity scheme outperforms the extrapolation approaches. For example, the following root-mean-squared deviations are obtained for the 140 basis-set limit CCSD atomization energies in the W4-11 database: 9.1 (global extrapolation), 3.7 (system-dependent extrapolation), and 2.4 (additivity scheme) kJ mol{sup –1}. The CCSD energy in these approximations is obtained from basis sets of up to TZ quality and the latter two approaches require additional MP2 calculations with basis sets of up to QZ quality. We also assess the performance of the basis-set extrapolations and additivity schemes for a set of 20 basis-set limit CCSD atomization energies of larger molecules including amino acids, DNA/RNA bases, aromatic compounds, and platonic hydrocarbon cages. We obtain the following RMSDs for the above methods: 10.2 (global extrapolation), 5.7 (system-dependent extrapolation), and 2.9 (additivity scheme) kJ mol{sup –1}.

  14. Advanced Test Reactor Safety Basis Upgrade Lessons Learned Relative to Design Basis Verification and Safety Basis Management

    International Nuclear Information System (INIS)

    The Advanced Test Reactor (ATR) is a pressurized light-water reactor with a design thermal power of 250 MW. The principal function of the ATR is to provide a high neutron flux for testing reactor fuels and other materials. The reactor also provides other irradiation services such as radioisotope production. The ATR and its support facilities are located at the Test Reactor Area of the Idaho National Engineering and Environmental Laboratory (INEEL). An audit conducted by the Department of Energy's Office of Independent Oversight and Performance Assurance (DOE OA) raised concerns that design conditions at the ATR were not adequately analyzed in the safety analysis and that legacy design basis management practices had the potential to further impact safe operation of the facility.1 The concerns identified by the audit team, and issues raised during additional reviews performed by ATR safety analysts, were evaluated through the unreviewed safety question process resulting in shutdown of the ATR for more than three months while these concerns were resolved. Past management of the ATR safety basis, relative to facility design basis management and change control, led to concerns that discrepancies in the safety basis may have developed. Although not required by DOE orders or regulations, not performing design basis verification in conjunction with development of the 10 CFR 830 Subpart B upgraded safety basis allowed these potential weaknesses to be carried forward. Configuration management and a clear definition of the existing facility design basis have a direct relation to developing and maintaining a high quality safety basis which properly identifies and mitigates all hazards and postulated accident conditions. These relations and the impact of past safety basis management practices have been reviewed in order to identify lessons learned from the safety basis upgrade process and appropriate actions to resolve possible concerns with respect to the current ATR safety

We prove that a "pattern basis" with certain properties would lead to a useful complexity formula of a specific form, and speculate on how to find such a basis. This formula might take as long to compute on arbitrary functions as a brute-force search among circ...

  19. Multiple Spawning with Optimal Basis Set Expansion

    CERN Document Server

    Yang, Sandy; Kaduk, Benjamin; Martinez, Todd J

    2008-01-01

    The Full Multiple Spawning (FMS) method is designed to simulate quantum dynamics in the multi-state electronic problem. The FMS nuclear wavefunction is represented in a basis of coupled, frozen Gaussians, and the spawning procedure prescribes a means of adaptively increasing the size of the basis in order to capture population transfer between electronic states. Parent trajectories create children when passing through regions of significant nonadiabatic coupling. In order to converge branching ratios without allowing the basis to reach an impractical size, population transfer at individual spawning events should be made as effective as possible. Herein we detail a new algorithm for specifying the initial conditions of freshly spawned basis functions, one that minimizes the number of spawns needed for convergence by maximizing the efficiency of individual spawning events. Optimization is achieved by maximizing the coupling between parent and child trajectories, as a function of child position and momentum, at ...

    A key point in the examination of the legality of antitrust practices is the delimitation of the relevant markets where the economic relations object of the analysis take place. This is the basis for the evaluation of the market power of the agents involved and the possible harm to competition they may cause. This work offers a study of the criteria for the determination of the relevant market in the scope of the natural gas industry in Brazil. It aims at identifying the performance of the agencies taking part in the Brazilian Antitrust System (SBDC) with regards to the examination of the related antitrust practices. These agencies work in connection with the National Petroleum, Natural Gas and Biofuels Regulatory Agency (ANP), which is responsible for issuing technical reports on the subjects related to its area of competence. The analysis presented here has the main goal of verifying if the most important technical, operational and legal aspects are being adequately considered by the SBDC and ANP in the definition of the relevant markets as a basis for the judgment of the antitrust practices, and if they are coherent with the principles for fostering economic competition. The results points out that, despite the successful cooperation between the SBDC and the ANP, there are the used definition of the relevant markets for the natural gas industry still needs refinement.

  5. ITER [International Thermonuclear Experimental Reactor] physics basis

    International Nuclear Information System (INIS)

    The physics basis of ITER has been developed from an assessment of the present knowledge of tokamak physics with allowance for improvements in that knowledge during the design and construction phases of ITER. The assessment has been carried out by the ITER design team in collaboration with the international fusion program, including participation by the experimental teams of all of the major toroidal experiments. The physics basis consists of guidelines for energy confinement, operational limits, power and particle control, disruptions, current drive and heating, alpha particle physics, and plasma control. The ITER physics group has worked with the engineering groups to implement these guidelines. In addition, a preliminary design for the plasma diagnostics for ITER has been developed and an operational program has been planned. In many cases, the physics issues have not been fully resolved, and a physics R ampersand D program has been developed to complete the physics basis for ITER. 16 refs., 3 tabs

    We study the heavy quarkonium within the basis light-front quantization approach. We implement the one-gluon exchange interaction and a confining potential inspired by light-front holography. We adopt the holographic light-front wavefunction (LFWF) as our basis function and solve the non-perturbative dynamics by diagonalizing the Hamiltonian matrix. We obtain the mass spectrum for charmonium and bottomonium. With the obtained LFWFs, we also compute the decay constants and the charge form factors for selected eigenstates. The results are compared with the experimental measurements and with other established methods.

    2013-01-01

    The radial basis function (RBF) interpolation approach proposed by Freedman is used to solve inverse problems encountered in well-logging and other petrophysical issues. The approach is to predict petrophysical properties in the laboratory on the basis of physical rock datasets, which include the formation factor, viscosity, permeability, and molecular composition. However, this approach does not consider the effect of spatial distribution of the calibration data on the interpolation result. This study proposes a new RBF interpolation approach based on the Freedman's RBF interpolation approach, by which the unit basis functions are uniformly populated in the space domain. The inverse results of the two approaches are comparatively analyzed by using our datasets. We determine that although the interpolation effects of the two approaches are equivalent, the new approach is more flexible and beneficial for reducing the number of basis functions when the database is large, resulting in simplification of the interpolation function expression. However, the predicted results of the central data are not sufficiently satisfied when the data clusters are far apart.

  20. PRELIMINARY SELECTION OF MGR DESIGN BASIS EVENTS

    International Nuclear Information System (INIS)

    The purpose of this analysis is to identify the preliminary design basis events (DBEs) for consideration in the design of the Monitored Geologic Repository (MGR). For external events and natural phenomena (e.g., earthquake), the objective is to identify those initiating events that the MGR will be designed to withstand. Design criteria will ensure that radiological release scenarios resulting from these initiating events are beyond design basis (i.e., have a scenario frequency less than once per million years). For internal (i.e., human-induced and random equipment failures) events, the objective is to identify credible event sequences that result in bounding radiological releases. These sequences will be used to establish the design basis criteria for MGR structures, systems, and components (SSCs) design basis criteria in order to prevent or mitigate radiological releases. The safety strategy presented in this analysis for preventing or mitigating DBEs is based on the preclosure safety strategy outlined in ''Strategy to Mitigate Preclosure Offsite Exposure'' (CRWMS M andO 1998f). DBE analysis is necessary to provide feedback and requirements to the design process, and also to demonstrate compliance with proposed 10 CFR 63 (Dyer 1999b) requirements. DBE analysis is also required to identify and classify the SSCs that are important to safety (ITS)

  5. Fundamentals of futures, options, basis and derivatives

    International Nuclear Information System (INIS)

    Characteristic features of futures and options contracts, basis differentials and derivatives were defined and explained. A futures contract refers to an exchange-traded supply contract between a buyer and a seller where the buyer is obligated to take delivery and the seller is obligated to provide delivery of a fixed amount of a commodity at a predetermined price at a specified location. In contrast, an option contract gives the purchaser the right, but not the obligation, to buy or sell the underlying commodity at a certain price on or before an agreed date. Basis differential refers to the discount between two distinct delivery points to reflect the relative value of a commodity, such as natural gas, at those points. Advantages and disadvantages of futures and options contacts, the factors affecting options pricing, and basis differentials, and the methods of calculating basis differentials were described. The nature and intricacies of derivatives, their benefits, in particular their use as a tool for the effective management of the volatilities associated with the oil and gas industry were explained. Their shortcomings such as the high liquidity risk, were also described. Examples of derivative transactions were provided to illustrate the interrelationships of futures/options/derivatives, and their role in financial risk management

  6. A reduced basis localized orthogonal decomposition

    Science.gov (United States)

    Abdulle, Assyr; Henning, Patrick

    2015-08-01

    In this work we combine the framework of the Reduced Basis method (RB) with the framework of the Localized Orthogonal Decomposition (LOD) in order to solve parametrized elliptic multiscale problems. The idea of the LOD is to split a high dimensional Finite Element space into a low dimensional space with comparably good approximation properties and a remainder space with negligible information. The low dimensional space is spanned by locally supported basis functions associated with the node of a coarse mesh obtained by solving decoupled local problems. However, for parameter dependent multiscale problems, the local basis has to be computed repeatedly for each choice of the parameter. To overcome this issue, we propose an RB approach to compute in an "offline" stage LOD for suitable representative parameters. The online solution of the multiscale problems can then be obtained in a coarse space (thanks to the LOD decomposition) and for an arbitrary value of the parameters (thanks to a suitable "interpolation" of the selected RB). The online RB-LOD has a basis with local support and leads to sparse systems. Applications of the strategy to both linear and nonlinear problems are given.

  9. System Design and the Safety Basis

    International Nuclear Information System (INIS)

    The objective of this paper is to present the Bechtel Jacobs Company, LLC (BJC) Lessons Learned for system design as it relates to safety basis documentation. BJC has had to reconcile incomplete or outdated system description information with current facility safety basis for a number of situations in recent months. This paper has relevance in multiple topical areas including documented safety analysis, decontamination and decommissioning (D and D), safety basis (SB) implementation, safety and design integration, potential inadequacy of the safety analysis (PISA), technical safety requirements (TSR), and unreviewed safety questions. BJC learned that nuclear safety compliance relies on adequate and well documented system design information. A number of PIS As and TSR violations occurred due to inadequate or erroneous system design information. As a corrective action, BJC assessed the occurrences caused by systems design-safety basis interface problems. Safety systems reviewed included the Molten Salt Reactor Experiment (MSRE) Fluorination System, K-1065 fire alarm system, and the K-25 Radiation Criticality Accident Alarm System. The conclusion was that an inadequate knowledge of system design could result in continuous non-compliance issues relating to nuclear safety. This was especially true with older facilities that lacked current as-built drawings coupled with the loss of 'historical knowledge' as personnel retired or moved on in their careers. Walkdown of systems and the updating of drawings are imperative for nuclear safety compliance. System design integration with safety basis has relevance in the Department of Energy (DOE) complex. This paper presents the BJC Lessons Learned in this area. It will be of benefit to DOE contractors that manage and operate an aging population of nuclear facilities

  11. A Discrete Adapted Hierarchical Basis Solver For Radial Basis Function Interpolation

    CERN Document Server

    Castrillon-Candas, Julio Enrique; Eijkhout, Victor

    2011-01-01

    In this paper we develop a discrete Hierarchical Basis (HB) to efficiently solve the Radial Basis Function (RBF) interpolation problem with variable polynomial order. The HB forms an orthogonal set and is adapted to the kernel seed function and the placement of the interpolation nodes. Moreover, this basis is orthogonal to a set of polynomials up to a given order defined on the interpolating nodes. We are thus able to decouple the RBF interpolation problem for any order of the polynomial interpolation and solve it in two steps: (1) The polynomial orthogonal RBF interpolation problem is efficiently solved in the transformed HB basis with a GMRES iteration and a diagonal, or block SSOR preconditioner. (2) The residual is then projected onto an orthonormal polynomial basis. We apply our approach on several test cases to study its effectiveness, including an application to the Best Linear Unbiased Estimator regression problem.

  14. RATIONAL BASIS FOR SUSPENDED SEDIMENT MODELING

    Institute of Scientific and Technical Information of China (English)

    Jianjun ZHOU; Binliang LIN; Bingnan LIN

    2003-01-01

    This paper presents a rational basis to model the transport of suspended sediment. The looseboundary condition for 3D models and the adjustment coefficients for both the depth-integrated 2D and laterally integrated 1D models are treated comprehensively. A combination of Dirichlet and Neumann conditions is proposed as the loose-boundary condition. The adjustment coefficient for 2D models is obtained on the basis of the proposed boundary condition and analytical solutions developed for some simple cases of non-equilibrium transport of sediment in uniform flows. The adjustment coefficient for 1D models for natural rivers is further obtained from lateral integration. Comparisons with analytical solutions and a considerable amount of laboratory and prototype data show that mathematical models developed along the proposed line of attack would well simulate the transport of suspended sediment in practical problems.

    Recently, new spreading sequences have been proposed to multiplex the capacity of users. In particular, Weyl spreading sequences have the larger capacity of users than Gold code. This paper shows that Weyl spreading sequences appear in bit restoring model and they are orthogonal basis in the particular situation. This result shows the reason why they have the large capacity and that any spreading sequence are expressed as the sum of Weyl spreading sequences.

  11. Calibration of options on a reduced basis

    Pironneau, Olivier

    2009-10-01

    Calibration of models is an important step in financial engineering. However it can be costly, especially in view of the increasing complexity of the models. In this paper we explore the use of reduced basis as is done in fluid mechanics for the Navier-Stokes equations or as proposed by Maday, Patera and Turinici [Y. Maday et al., A priori convergence theory for reduced-basis approximations of single-parameter elliptic partial differential equations, J. Sci. Comput. 17 (1-4) (2002) 437-446]. It is shown that the method works well if we use convex combination of the basis functions instead of the more general linear combination; however, while this idea makes sense in view of the properties of the Black-Scholes equation, we have no proof to general linear combination; however, while this idea makes sense in view of the properties of the Black-Scholes equation, we have no proof to justify it mathematically. The paper presents a numerical investigation of the problem posed.

  12. Accurate basis set truncation for wavefunction embedding

    Science.gov (United States)

    Barnes, Taylor A.; Goodpaster, Jason D.; Manby, Frederick R.; Miller, Thomas F.

    2013-07-01

    Density functional theory (DFT) provides a formally exact framework for performing embedded subsystem electronic structure calculations, including DFT-in-DFT and wavefunction theory-in-DFT descriptions. In the interest of efficiency, it is desirable to truncate the atomic orbital basis set in which the subsystem calculation is performed, thus avoiding high-order scaling with respect to the size of the MO virtual space. In this study, we extend a recently introduced projection-based embedding method [F. R. Manby, M. Stella, J. D. Goodpaster, and T. F. Miller III, J. Chem. Theory Comput. 8, 2564 (2012)], 10.1021/ct300544e to allow for the systematic and accurate truncation of the embedded subsystem basis set. The approach is applied to both covalently and non-covalently bound test cases, including water clusters and polypeptide chains, and it is demonstrated that errors associated with basis set truncation are controllable to well within chemical accuracy. Furthermore, we show that this approach allows for switching between accurate projection-based embedding and DFT embedding with approximate kinetic energy (KE) functionals; in this sense, the approach provides a means of systematically improving upon the use of approximate KE functionals in DFT embedding.

  13. Variable-basis Categorically-algebraic Dualities

    Directory of Open Access Journals (Sweden)

    Sergey A. Solovyov

    2014-12-01

    Full Text Available The manuscript continues our study on developing a categorically-algebraic (catalg analogue of the theory of natural dualities of D. Clark and B. Davey, which provides a machinery for obtaining topological representations of algebraic structures. The new setting differs from its predecessor in relying on catalg topology, introduced lately by the author as a new approach to topological structures, which incorporates the majority of both crisp and many-valued developments, ultimately erasing the border between them. Motivated by the variable-basis lattice-valued extension of the Stone representation theorems done by S. E. Rodabaugh, we have recently presented a catalg version of the Priestley duality for distributive lattices, which gave rise (as in the classical case to a fixed-basis variety-based approach to natural dualities. In this paper, we extend the theory to variable-basis, whose setting is completely different from the respective one of S. E. Rodabaugh, restricted to isomorphisms between the underlying lattices of the spaces.

  14. The Teleological Resocialization: theoretical-praxeological basis

    Directory of Open Access Journals (Sweden)

    Sławomir Sobczak

    2011-12-01

    Full Text Available Resocialization and Social Prevention is a theoretical and a praxeological subject, thus teleology of resocialization as its building block should relate both to its theoretical and practical aspects, i.e. to goals and postulates formed on the basis of paradigms and diagnosis. In the article are pointed out the reasons for forming teleology of resocialization due to the foundation of fundamental thinking, i.e. monistic basis (idealism, materialism and pluralism (realism and also the outcomes of making presumptions in aspects of the process of planning deliberate actions. On one hand the modern praxeology points to forming the goals of the treatment in the phase of equifinality on the basis of the diagnosis as an information on the system, on the other hand the theoretical aspect of resocialization teleology is described imprecisely, from only one angle. In resocialization teleology there is a narrowing to idealistic or material thinking, which considers axiology as the foundation of forming goals, according to their way of thinking. Having a particular way of thinking is not a mistake. It is, however, a mistake to inform the reader in books that this way of thinking is the only way, though not too suitable, but having no alternative. In the available literature on the subject both the axiological and anthropological bases of teleology are formed. Therefore, neither the axiology nor anthropology should be mentioned as an equivalent to teleology, instead the teleology as a knowledge can only be based on either the axiology or anthropology.

  15. Beyond design basis issues in Spain

    International Nuclear Information System (INIS)

    Following the accident on 11 March 2011 at the Fukushima Daiichi NPP, the CSN submitted a complementary technical instruction, requiring Spanish NPPs to perform stress tests consistent with the work of European safety authorities (the Western European Nuclear Regulators Association and the European Nuclear Safety Regulators Group). The main topics for evaluation were: earthquakes, external floods beyond design basis, prolonged station blackout combined with loss of heat sink, emergency organization and resources, severe accident management and the management of degraded condition in the spent fuel pools. As a result of the stress test analysis, commitments for changes and modifications that go beyond the plant design basis were made. The commitments are grouped into three categories: short term (2012); medium term (2014); and long term (2014). Other activities related to beyond design basis have been the analysis and the commitments made to improve management of large fires, and improved explosion prevention capability. These activities, and the follow-up commitments, were in response to a CSN complementary technical instruction

    The objective of this study is to collect and evaluate environmentally relevant data on mineral oil additives and their combustion products. In addition, their concentration ranges, chemistry and functions in the mineral oils are described. Lubricant and fuel additives belong to the quantitatively most important chemicals with a total quantity of 84600 tons estimated for Germany 1997/98 (57400 tons of lubricant additives, 27200 tons of fuel additives). They determine substantially the characteristic profile of engine oils, gasoline and diesel. Main lubricant additive families are detergents, dispersants, antioxidant / antiwear agents (ZDTP), inhibitors, and viscosity modifiers. Examples for fuel additives are detergents, antioxidants, corrosion inhibitors, cetane improvers (diesel), and wax crystal modifiers (diesel). Based on the information available in the literature and provided by the manufacturers the environmental fate of the additives is explored, and inventories (calculations of the input and output) are presented. Data for emission volumes were calculated on this basis and additional 'reasonable worst case' assumptions. But as measurement data in this area is very limited, the calculated emissions are uncertain. Comparison of the emitted additive combustion products (CO{sub 2}, CO, NO{sub 2}, NMVOC, particulate matter) with exhaust limit values for tail pipe emissions and total traffic emissions in Germany showed that the contribution of additive combustion products to particles is more significant than to other fractions. The results of the calculations indicate that the portion of mineral oil additives of the traffic-dependent particle emissions in Germany is approximately 7% (ca. 3/5 from lubricant additives and ca. 2/5 from fuel additives). (orig.) [German] Ziel dieser Studie ist es, umweltrelevante Daten zu Mineraloel-Additiven und ihren Verbrennungsprodukten zusammenzustellen und zu bewerten. Hierzu werden u.a. auch die Additiv

  17. The EPRI preventive maintenance basis products

    International Nuclear Information System (INIS)

    Electric utilities need a technical basis to support preventive maintenance (PM) tasks in all types of power plants for common major components. This paper describes and demonstrates the PM basis products which have been developed by EPRI to provide the utility user with an essential reference for PM tasks and intervals for 45 component types. These products also provide in-depth technical basis information to adapt the PM tasks and intervals to plant conditions. Data for each component type embodies all the PM tasks, intervals, task objectives and scope, and the most important influences on equipment degradation and maintenance for that specific component. The data were developed by expert groups of utility maintenance and vendor personnel, who provided information on equipment degradation and PM options in workshop sessions. The EPRI PM basis products consist of, 1) 40 published reports and a project overview report, 2) a stand-alone Access 97 database, 3) a web-site hosting a server-based version which permits use of the database, and feedback of utility PM experience, 4) a PM basis working group of about a dozen utilities, and 5) documentation and training materials. The electronic databases contain an integrated application guideline which provides state-of-the-art guidance on technical decision making to support a PM program. These topics include use of the database to, 1) evaluate PM tasks and task intervals, 2) improve predictive maintenance usage, 3) make decisions on task deferrals, 4) provide source material for as-found condition reporting and evaluation, 5) provide completeness checks on failure cause evaluation, and 6) to conduct quick PM assessments at a plant. The showcase of the web site application is the vulnerability analysis tool which analyzes the complete set of recommended tasks and intervals, shows the overall effectiveness with which each degradation mechanism is addressed by each task, and summarizes the extent and depth of protection

    Science.gov (United States)

    Di Cera, E

    1994-08-01

    Cooperative phenomena in biological macromolecules arise from the interaction of many distinct subsystems, such as structural domains or binding sites. Cooperative properties of the system as a whole, like protein folding or allosteric transitions, are subject to the restrictions imposed by thermodynamic stability. These restrictions, however, do not apply in the case of individual subsystems open to interactions with the rest of the macromolecule. The site-specific properties of such subsystems can be understood in general thermodynamic terms from those of a multicomponent system under particular conditions. The analogy provides a thermodynamic basis for site-specific cooperativity. PMID:8075382

    In order to understand questions about the study on cold fusion in these years, we have studied physical basis of cold fusion. Results show that even though the cold fusion is feasible theoretically in the view of physics, but its reaction ratio is too small to be detected, so that it has no prospect for practical usage at present. However, in order to tackle urgent problem of being poor in energy resources, we have no choice but to pay more attention to controlled thermal nuclear fusion in a considerably long period of time.

    This report describes the design basis of thermohydrodynamics for the 20 MWt research reactor, JRR-3, which is to be constructed at the Japan Atomic Energy Research Institute (JAERI), based on the investigation of the thermohydrodynamic characteristics for the JRR-3. Thermohydrodynamic characteristics at the condition of normal operation were investigated to confirm that the JRR-3 design satisfies the design criteria for the normal operation condition. Besides, key items were also investigated which are necessary to evaluate the safety margin of the JRR-3 design for the operational transients and accidents. (author)

    In this paper we highlight why there is a need to examine subcortical learning systems in children with language impairment and dyslexia, rather than focusing solely on cortical areas relevant for language. First, behavioural studies find that children with these neurodevelopmental disorders perform less well than peers on procedural learning tasks that depend on corticostriatal learning circuits. Second, fMRI studies in neurotypical adults implicate corticostriatal and hippocampal systems in language learning. Finally, structural and functional abnormalities are seen in the striatum in children with language disorders. Studying corticostriatal networks in developmental language disorders could offer us insights into their neurobiological basis and elucidate possible modes of compensation for intervention.

    Full Text Available Resumen:En este artículo se presenta parte de los resultados obtenidos en una investigación realizada entre los años 2009 y 2010 en una comunidad rural en México donde participaron 12 personas que abandonaron la escuela tele-secundaria. El estudio es de tipo cualitativo y las principales herramientas para obtener la información fueron la historia de vida y la entrevista abierta. La pregunta que orienta este artículo analiza las formas en cómo los alumnos traducen el curriculum formal en una experiencia escolar relevante y cómo influye tal significado en la permanencia. Los principales resultados señalan que la relación profesor-alumno, el trato entre pares y el apoyo de la familia, son elementos importantes para mejorar la permanencia y la calidad de los aprendizajes, así como para otorgar significado relevante a esa experiencia. En las conclusiones del estudio se muestra que el valor positivo hacia la escuela y la relevancia de la experiencia escolar, no son elementos suficientes para garantizar la permanencia, pues en esa decisión intervienen otros factores y razonamientos particulares. Es decir, cada alumno, en su mundo de vida construye un sentido de la realidad y este es el que orienta sus decisiones; una de ellas es permanecer o retirarse de la escuela. En este marco de relativa autonomía, los profesores estamos obligados a ofrecer a los alumnos la oportunidad de vivir una experiencia escolar relevante que les permita desenvolverse en un mundo complejo y aprender a lo largo de la vida, más allá de su condición y disposición para permanecer en la escuela.Abstract: This article I share part of the results of an investigation developed during the 2009 and 2010 year in a rural community in Mexico.

METHODS: The first step was to conceptualize and define the construct, determining how much the elderly are able to perform of what they believe to be important in their lives and whether they are satisfied with what was possible to perform. The next step was to select and describe the construction methodology (the Clinical Impact Method and the phase of generation of relevant items for the research object. The necessary procedures were delineated through a pilot study, which helped to establish all phases of the used methodology. The viability of the construction of the Quality of Life in Old Age evaluation instrument was demonstrated along with the needed adaptations. RESULTS: From 1032 answers by older people, 138 relevant items for the construct were identified by the items generation process. The pilot study demonstrated the suitability of the application of the methodology and established modifications to the preliminary items list, resulting in a new 139-item list. DISCUSSION: Now that the theoretical-conceptual framework of the construct as well as the construction methodology and the items generation are established, the next step will consist of administering the resulting list to a sample of elderly people for item reduction and distribution of items into dimensions.OBJETIVO: Descrever os passos iniciais do processo de construção de um instrumento de avaliação de qualidade de vida de idosos: a base teórico-conceitual do constructo Qualidade de Vida na Velhice, a metodologia escolhida para a construção e a geração dos itens relevantes.

  18. Scientific basis for nuclear waste management XVII

    International Nuclear Information System (INIS)

    The 17th Materials Research Society Symposium on the Scientific Basis for Nuclear Waste Management included 17 sessions, during which 120 papers were presented by scientists from 16 countries. The nuclear waste glass overview surveyed achievements to date and identified issues requiring further research. The objectives and limitations session noted the progress that has been made in developing a scientific basis for nuclear waste management, but questioned whether regulations calling for detailed predictions over a period of 10,000 years are either necessary or capable of being satisfied. The other papers presented at the Symposium described the progress of studies in a broad array of areas of nuclear waste science and technology. These areas included radiation effects and gas generation, ceramic materials, cementitious materials, actinides spent fuel, glass processing and properties, glass leaching, dissolution and alteration, natural and ancient analogues, transuranic wastes and special topics, sorption mechanisms, repository studies, geochemistry and hydrology, containers, and backfill materials. Several novel experimental techniques were described, as well as advances in modeling. An encouraging feature of the progress in modeling is that the agreement between calculated results based on models developed, refined and tested in the US and in other countries on one hand, and experimental data on the other, shows considerable improvement. This reflects greater understanding of the mechanisms involved in the release of radionuclides from the various components of the waste repository system, including the wasteforms themselves. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database

  19. Basis for calculations in the topological expansion

    International Nuclear Information System (INIS)

    Investigations aimed at putting the topological theory of particles on a more quantitative basis are described. First, the incorporation of spin into the topological structure is discussed and shown to successfully reproduce the observed lowest mass hadron spectrum. The absence of parity-doubled states represents a significant improvement over previous efforts in similar directions. This theory is applied to the lowest order calculation of elementary hadron coupling constant ratios. SU(6)/sub W/ symmetry is maintained and extended via the notions of topological supersymmetry and universality. Finally, efforts to discover a perturbative basis for the topological expansion are described. This has led to the formulation of off-shell Feynman-like rules which provide a calculational scheme for the strong interaction components of the topological expansion once the zero-entropy connected parts are known. These rules are shown to imply a topological asymptotic freedom. Even though the nonlinear zero-entropy problem cannot itself be treated perturbatively, plausible general assumptions about zero-entropy amplitudes allow immediate qualitative inferences concerning physical hadrons. In particular, scenarios for mass splittings beyond the supersymmetric level are described

  1. The Interpolation Theory of Radial Basis Functions

    Baxter, Brad

    2010-01-01

    In this dissertation, it is first shown that, when the radial basis function is a $p$-norm and $1 2$. Specifically, for every $p > 2$, we construct a set of different points in some $\\Rd$ for which the interpolation matrix is singular. The greater part of this work investigates the sensitivity of radial basis function interpolants to changes in the function values at the interpolation points. Our early results show that it is possible to recast the work of Ball, Narcowich and Ward in the language of distributional Fourier transforms in an elegant way. We then use this language to study the interpolation matrices generated by subsets of regular grids. In particular, we are able to extend the classical theory of Toeplitz operators to calculate sharp bounds on the spectra of such matrices. Applying our understanding of these spectra, we construct preconditioners for the conjugate gradient solution of the interpolation equations. Our main result is that the number of steps required to achieve solution of the lin...

  2. Spherical radial basis functions, theory and applications

    CERN Document Server

    Hubbert, Simon; Morton, Tanya M

    2015-01-01

    This book is the first to be devoted to the theory and applications of spherical (radial) basis functions (SBFs), which is rapidly emerging as one of the most promising techniques for solving problems where approximations are needed on the surface of a sphere. The aim of the book is to provide enough theoretical and practical details for the reader to be able to implement the SBF methods to solve real world problems. The authors stress the close connection between the theory of SBFs and that of the more well-known family of radial basis functions (RBFs), which are well-established tools for solving approximation theory problems on more general domains. The unique solvability of the SBF interpolation method for data fitting problems is established and an in-depth investigation of its accuracy is provided. Two chapters are devoted to partial differential equations (PDEs). One deals with the practical implementation of an SBF-based solution to an elliptic PDE and another which describes an SBF approach for solvi...

  3. The genetic basis of sleep disorders.

    2008-01-01

    The contribution of genes, environment and gene-environment interactions to sleep disorders is increasingly recognized. Well-documented familial and twin sleep disorder studies suggest an important influence of genetic factors. However, only few sleep disorders have an established genetic basis including four rare diseases that may result from a single gene mutation: fatal familial insomnia, familial advanced sleep-phase syndrome, chronic primary insomnia, and narcolepsy with cataplexy. However, most sleep disorders are complex in terms of their genetic susceptibility together with the variable expressivity of the phenotype even within a same family. Recent linkage, genome-wide and candidate gene association studies resulted in the identification of gene mutations, gene localizations, or evidence for susceptibility genes and/or loci in several sleep disorders. Molecular techniques including mainly genome-wide linkage and association studies are further required to identify the contribution of new genes. These identified susceptibility genetic determinants will provide clues to better understand pathogenesis of sleep disorders, to assess the risk for diseases and also to find new drug targets to treat and to prevent the underlying conditions. We reviewed here the role of genetic basis in most of key sleep disorders. PMID:19075715

  4. Technical Basis for PNNL Beryllium Inventory

    2014-07-09

    The Department of Energy (DOE) issued Title 10 of the Code of Federal Regulations Part 850, “Chronic Beryllium Disease Prevention Program” (the Beryllium Rule) in 1999 and required full compliance by no later than January 7, 2002. The Beryllium Rule requires the development of a baseline beryllium inventory of the locations of beryllium operations and other locations of potential beryllium contamination at DOE facilities. The baseline beryllium inventory is also required to identify workers exposed or potentially exposed to beryllium at those locations. Prior to DOE issuing 10 CFR 850, Pacific Northwest Nuclear Laboratory (PNNL) had documented the beryllium characterization and worker exposure potential for multiple facilities in compliance with DOE’s 1997 Notice 440.1, “Interim Chronic Beryllium Disease.” After DOE’s issuance of 10 CFR 850, PNNL developed an implementation plan to be compliant by 2002. In 2014, an internal self-assessment (ITS #E-00748) of PNNL’s Chronic Beryllium Disease Prevention Program (CBDPP) identified several deficiencies. One deficiency is that the technical basis for establishing the baseline beryllium inventory when the Beryllium Rule was implemented was either not documented or not retrievable. In addition, the beryllium inventory itself had not been adequately documented and maintained since PNNL established its own CBDPP, separate from Hanford Site’s program. This document reconstructs PNNL’s baseline beryllium inventory as it would have existed when it achieved compliance with the Beryllium Rule in 2001 and provides the technical basis for the baseline beryllium inventory.

  5. Modelling erosion on a daily basis

    2016-04-01

    Effect of soil erosion causing negative impact on ecosystem services and food security is well known. To assess annual erosion rates various empirical models have been extensively used in all the climatic regions. While these models are simple to operate and do not require lot of input data, the effect of extreme rain is not taken into account in the annual estimations. For analysing the effects of extreme rain the event- based models become handy. These models can simulate detail erosional processes including particle detachment, transportation and deposition of sediments during a storm. But they are not applicable for estimating annual erosion rates. Moreover storm event data may not be available everywhere which prohibits their extensive use. In this paper we describe a method by adapting the revised MMF model to assess erosion on daily basis so that the effects of extreme rains are taken into account. We couple it to a simple surface soil moisture balance on a daily basis and include estimation of daily vegetation cover changes. Annual soil loss is calculated by adding daily erosion rates. We compare the obtained results with that obtained from applying the revised MMF model in a case study in the Mamora plateau in northwest Morocco which is affected by severe gully formation. The results show clearly the effects of exceptional rain in erosional processes which cannot be captured in an annual model.

  6. A Scientific Basis for Climate Policy

    International Nuclear Information System (INIS)

    The Scientific Council on Climate Issues has been commissioned by the Swedish Government to provide a scientific assessment as a basis for the work of the Climate Committee, the all-party committee for the review of climate policy. An important part of this task is to provide a basis and recommendations for Swedish climate policy targets at national, EU and international level. In the opening chapters, the Council looks at climate change, its reasons and its consequences for ecosystems and society. The Council then makes recommendations concerning Swedish climate policy targets at global, EU and national levels, aimed at averting dangerous impact on the climate. In the concluding chapters, the Council presents a number of possible measures and policy instruments, and outlines the likely costs involved if the goals are to be achieved. Taken as a whole, the document represents a comprehensive basis for policy decisions that consider what needs to be achieved to reduce the risks of climate impact and what is actually achievable, i.e. decisions involving trade-offs between economic benefits and costs. The Council considers: that the EU's GHG emissions compared to the 1990 level should be reduced by 30-40 % by 2020 and by 75-90 % by 2050 if the Union is to take its share of the global responsibility for achievement of the two-degree target; that Sweden's GHG emissions compared to the 1990 level should be reduced by 20-25 % by 2020 and by 70-85 % by 2050 if Sweden is to take its share of the global responsibility for achievement of the two-degree target; that a national emission target for Sweden should be formulated as a target with deductible emissions allowances, i.e., that assessment of target achievement is based on the amount of emission allowances allocated or auctioned by Sweden to activities covered by the EU emissions trading scheme rather than the actual volume of emissions from these activities. The Council has provided an overview of possible measures for

    2013-06-01

    The dominance of East African distance runners and sprinters of West African origin invites discussion around the contribution of genetic and lifestyle factors to performance. In this review, we focus on the genetic basis for performance. Previous research associating candidate genes such as ACE and ACTN3 to endurance and sprint performance in Caucasian populations has not been replicated in African populations. This may be influenced by numerous factors, including small sample sizes, comparisons across different ethnic populations and problems identifying appropriate control groups. Conceptually, these failures reveal the complex polygenic nature of physiology and performance, and the erroneous application of a candidate gene approach to more genetically diverse African populations. We argue that research has in fact established a role for genes in performance, and that the frequency, rather than the prevalence, of favourable genetic variants within certain populations may account for the performance dominance in these populations.

  8. Prototype Hanford Surface Barrier: Design basis document

    International Nuclear Information System (INIS)

    The Hanford Site Surface Barrier Development Program (BDP) was organized in 1985 to develop the technology needed to provide a long-term surface barrier capability for the Hanford Site and other arid sites. This document provides the basis of the prototype barrier. Engineers and scientists have momentarily frozen evolving barrier designs and incorporated the latest findings from BDP tasks. The design and construction of the prototype barrier has required that all of the various components of the barrier be brought together into an integrated system. This integration is particularly important because some of the components of the protective barreir have been developed independently of other barreir components. This document serves as the baseline by which future modifications or other barrier designs can be compared. Also, this document contains the minutes of meeting convened during the definitive design process in which critical decisions affecting the prototype barrier's design were made and the construction drawings

    2013-12-01

    Full Text Available Analyses of pedagogical and psychological literature show that education and upbringing are oriented to nursing moral values. In pedagogy’s historical context, the most important goals are education, development, and self-development of life experience and student’s perception of efforts to build values in their own life.In different historical periods, different moral values appear in the society. They are united by being directed towards humanism and on the basis of personal experience they represent completeness of general principles and norms of student’s behavior towards other people, nature, society and towards student’s themselves in the name of the common good. The already formed moral values have regulatory function in student’s life.The research problem is connected with humanization of the educational process.

    The work is devoted to Computability Logic (CoL) -- the philosophical/mathematical platform and long-term project for redeveloping classical logic after replacing truth} by computability in its underlying semantics (see http://www.cis.upenn.edu/~giorgi/cl.html). This article elaborates some basic complexity theory for the CoL framework. Then it proves soundness and completeness for the deductive system CL12 with respect to the semantics of CoL, including the version of the latter based on polynomial time computability instead of computability-in-principle. CL12 is a sequent calculus system, where the meaning of a sequent intuitively can be characterized as "the succedent is algorithmically reducible to the antecedent", and where formulas are built from predicate letters, function letters, variables, constants, identity, negation, parallel and choice connectives, and blind and choice quantifiers. A case is made that CL12 is an adequate logical basis for constructive applied theories, including complexity-orien...

  14. Nuclear energy - basis for hydrogen economy

    International Nuclear Information System (INIS)

    The development of human civilization in general as well as that of every country in particular is in direct relation to the assurance of a cost effective energy balance encompassing all industrial spheres and everyday activities. Unfortunately, the uncontrolled utilization of Earth's energy resources is already causing irreversible damage to various components of the eco-system of the Earth. Nuclear energy used for electricity and hydrogen production has the biggest technological potential for solving of the main energy outstanding issues of the new century: increasing of energy dependence; global warming. Because of good market position the political basis is assured for fast development of new generation nuclear reactors and fuel cycles which can satisfy vigorously increasing needs of affordable and clean energy. Political conditions are created for adequate participation of nuclear energy in the future global energy mix. They must give chance to the nuclear industry to take adequate part in the new energy generation capacity.(author)

  15. The neural basis of human tool use

    Directory of Open Access Journals (Sweden)

    FaustoCaruana

    2014-04-01

    Full Text Available In this review, we propose that the neural basis for the spontaneous, diversified human tool use is an area devoted to the execution and observation of tool actions, located in the left anterior supramarginal gyrus (aSMG. The aSMG activation elicited by observing tool use is typical of human subjects, as macaques show no similar activation, even after an extensive training to use tools. The execution of tool actions, as well as their observation, requires the convergence upon aSMG of inputs from different parts of the dorsal and ventral visual streams. Non semantic features of the target object may be provided by the posterior parietal cortex (PPC for tool-object interaction, paralleling the well-known PPC input to AIP for hand-object interaction. Semantic information regarding tool identity, and knowledge of the typical manner of handling the tool, could be provided by inferior and middle regions of the temporal lobe. Somatosensory feedback and technical reasoning, as well as motor and intentional constraints also play roles during the planning of tool actions and consequently their signals likewise converge upon aSMG.We further propose that aSMG may have arisen though duplication of monkey AIP and invasion of the duplicate area by afferents from PPC providing distinct signals depending on the kinematics of the manipulative action. This duplication may have occurred when Homo Habilis or Homo Erectus emerged, generating the Oldowan or Acheulean Industrial complexes respectively. Hence tool use may have emerged during hominid evolution between bipedalism and language.We conclude that humans have two parietal systems involved in tool behavior: a biological circuit for grasping objects, including tools, and an artifactual system devoted specifically to tool use. Only the latter allows humans to understand the causal relationship between tool use and obtaining the goal, and is likely to be the basis of all technological developments.

  16. Genetic Basis of Attention Deficit Hyperactivity Disorder

    2011-01-01

    Full Text Available Attention Deficit Hyperactivity Disorder (ADHD is one of the most common neuropsychiatric disorders of childhood. Due to studies reporting that the effects of ADHD diagnosis on functioning may last throughout life, this disorder, which has great importance for child and adolescent psychiatry, started to attract greater attention recently in terms of adult psychiatry. A review, evaluating the results of studies conducted on the genetic basis of ADHD, which started to attract increasing attention both in our country and the world, was thought to help clinicians working in this field. PubMed and Turkish Psychiatry Index online search engines were screened using “attention deficit hyperactivity disorder”, “ADHD”, “genetics” as key words. The data obtained were combined with information gleaned from several textbooks. Based on previous studies, it could easily be concluded that ADHD is one of the most common heritable psychiatric disorder with distinguished genetic features. Despite its importance for diagnosis and treatment, the etiology of ADHD is still not clear and the disorder seems to be a complex problem arising from the effects of both genetic and environmental factors. Although previous studies revealed that ADHD displayed familial and hereditary transmission, stable patterns of Mendelian inheritance could not be discriminated by evaluation of pedigrees. Therefore, many studies have been conducted on the molecular genetic basis of ADHD recently. The previous studies did not report consistent results in identification of the genes responsible for ADHD which has been partially linked to heterogeneity of the disorder. Grouping relevant patients according to comorbidities and persistence in adolescence rather than DSM-IV subtypes could be an important alternative method for overcoming this limitation in the research studies.

  17. Safeguards agreements - Their legal and conceptual basis

    International Nuclear Information System (INIS)

    The application of Agency safeguards requires treaty arrangements (Safeguards Agreements) between the State or States concerned and the Agency. The authority for the Agency to conclude such agreements and to implement them is provided for in the Agency's Statute. On the basis of the statutory provisions safeguards principles and procedures have been elaborated. These have been laid down in: The Agency's Safeguards System 1965, extended in 1966 and 1968; and the basis for negotiating safeguards agreements with NNWS pursuant to NPT. The verification of the undertaking by the State concerned not to use items subject to safeguards for purposes contrary to the terms of the agreement is ensured through the application of various safeguards measures. Containment and surveillance measures are expected to play an increasingly important role. One of the specific features of NPT Safeguards Agreements is the establishment of national systems of accounting and control of nuclear material. The majority of the agreements concluded under the non-NPT safeguards agreements implement obligations undertaken under co-operation agreements between States for peaceful uses of nuclear energy. These agreements naturally reflect approaches adopted by the parties, in particular regarding the circumstances under which safeguards should be applied. Thus, the concepts used in the non-NPT safeguards agreements and the Safeguards System document, which is incorporated in these agreements by reference, are in continuous evolution. The Agency's Safeguards System document (INFCIRC/66/Rev.2) continues to be supplemented in practical application and through explicit decision by the Board. The non-NPT safeguards agreements contain, besides technical safeguards provisions from this document, and further provision for notification, inventories and financial matters, legal and political provisions such as sanctions in the case of non-compliance, and privileges and immunities.

  18. Many-Body Basis Set Superposition Effect.

    The basis set superposition effect (BSSE) arises in electronic structure calculations of molecular clusters when questions relating to interactions between monomers within the larger cluster are asked. The binding energy, or total energy, of the cluster may be broken down into many smaller subcluster calculations and the energies of these subsystems linearly combined to, hopefully, produce the desired quantity of interest. Unfortunately, BSSE can plague these smaller fragment calculations. In this work, we carefully examine the major sources of error associated with reproducing the binding energy and total energy of a molecular cluster. In order to do so, we decompose these energies in terms of a many-body expansion (MBE), where a "body" here refers to the monomers that make up the cluster. In our analysis, we found it necessary to introduce something we designate here as a many-ghost many-body expansion (MGMBE). The work presented here produces some surprising results, but perhaps the most significant of all is that BSSE effects up to the order of truncation in a MBE of the total energy cancel exactly. In the case of the binding energy, the only BSSE correction terms remaining arise from the removal of the one-body monomer total energies. Nevertheless, our earlier work indicated that BSSE effects continued to remain in the total energy of the cluster up to very high truncation order in the MBE. We show in this work that the vast majority of these high-order many-body effects arise from BSSE associated with the one-body monomer total energies. Also, we found that, remarkably, the complete basis set limit values for the three-body and four-body interactions differed very little from that at the MP2/aug-cc-pVDZ level for the respective subclusters embedded within a larger cluster.

    Ikeda, K.

    2007-06-01

    I would firstly like to congratulate all who have contributed to the preparation of the `Progress in the ITER Physics Basis' (PIPB) on its publication and express my deep appreciation of the hard work and commitment of the many scientists involved. With the signing of the ITER Joint Implementing Agreement in November 2006, the ITER Members have now established the framework for construction of the project, and the ITER Organization has begun work at Cadarache. The review of recent progress in the physics basis for burning plasma experiments encompassed by the PIPB will be a valuable resource for the project and, in particular, for the current Design Review. The ITER design has been derived from a physics basis developed through experimental, modelling and theoretical work on the properties of tokamak plasmas and, in particular, on studies of burning plasma physics. The `ITER Physics Basis' (IPB), published in 1999, has been the reference for the projection methodologies for the design of ITER, but the IPB also highlighted several key issues which needed to be resolved to provide a robust basis for ITER operation. In the intervening period scientists of the ITER Participant Teams have addressed these issues intensively. The International Tokamak Physics Activity (ITPA) has provided an excellent forum for scientists involved in these studies, focusing their work on the high priority physics issues for ITER. Significant progress has been made in many of the issues identified in the IPB and this progress is discussed in depth in the PIPB. In this respect, the publication of the PIPB symbolizes the strong interest and enthusiasm of the plasma physics community for the success of the ITER project, which we all recognize as one of the great scientific challenges of the 21st century. I wish to emphasize my appreciation of the work of the ITPA Coordinating Committee members, who are listed below. Their support and encouragement for the preparation of the PIPB were

    O Brasil Republicano historicamente adotou o princípio da "não reeleição", o qual foi revogado pela Emenda Constitucional n° 16 de 04 de junho de 1997, aprovada em circunstâncias políticas controvertidas. A essência da reeleição é a de permitir que os políticos que atuem bem continuem sua trajetória, e aqueles que desagradem o eleitorado em seus governos não sejam reeleitos. Contudo, a avaliação de bom e mau governo é uma tarefa para a qual nem todos os eleitores brasileiros estão preparados,...

  7. Scientific basis for the Precautionary Principle

    International Nuclear Information System (INIS)

    The Precautionary Principle is based on two general criteria: (a) appropriate public action should be taken in response to limited, but plausible and credible, evidence of likely and substantial harm; (b) the burden of proof is shifted from demonstrating the presence of risk to demonstrating the absence of risk. Not much has been written about the scientific basis of the precautionary principle, apart from the uncertainty that characterizes epidemiologic research on chronic disease, and the use of surrogate evidence when human evidence cannot be provided. It is proposed in this paper that a new scientific paradigm, based on the theory of evolution, is emerging; this might offer stronger support to the need for precaution in the regulation of environmental risks. Environmental hazards do not consist only in direct attacks to the integrity of DNA or other macromolecules. They can consist in changes that take place already in utero, and that condition disease risks many years later. Also, environmental exposures can act as 'stressors', inducing hypermutability (the mutator phenotype) as an adaptive response. Finally, environmental changes should be evaluated against a background of a not-so-easily modifiable genetic make-up, inherited from a period in which humans were mainly hunters-gatherers and had dietary habits very different from the current ones

  9. Physicochemical and physiological basis of dichromatic colour

    Kreft, Samo; Kreft, Marko

    2007-11-01

    Out of three perceptual characteristics of the colour of any substance, the hue depends mostly on the spectral properties of a substance, while the brightness and saturation depend also on the concentration of a substance and its thickness. Here, we report that evident change of the hue of the colour (i.e., from green to red) is due to a change in concentration or the thickness of a layer in some exceptional substances such as pumpkin seed oil or an aqueous solution of bromophenol blue. In some regions of Central Europe, salad dressing is made preferably with the pumpkin seed oil, which has a strong characteristic nut-like taste and remarkable properties of the colour: it appears red in a bottle, but green when served as a salad dressing. The colour of the pumpkin seed oil was previously described as brownish yellow, dark green, dark green to red ochre or dark reddish brown to light yellow green. We elucidated the physicochemical and physiological basis of such dichromatism by Beer-Lambert law and by the characteristics of human colour perception. Our concept was corroborated by the outcome of calculations of colour from spectral properties using colour matching functions. We found that dichromatism is observed if the absorption spectrum of any substance has at least two local minima: one wide but shallow and one narrow but deep local minimum.

  10. Accelerated Best Basis Inventory Baselining Task

    International Nuclear Information System (INIS)

    The objectives of the Best Basis Inventory (BBI) baselining effort are to: (1) Provide inventories that are consistent with the revised BBI methodology and new BBI creation rules. (2) Split the total tank waste in each tank into six waste phases, as appropriate (Supernatant, saltcake solids, saltcake liquid, sludge solids, sludge liquid, and retained gas). (3) Identify sampling events that are to be used for calculating the BBIs. (4) Update waste volumes for subsequent reconciliation with the Hanlon (2000) waste tank summary. (5) Implement new waste type templates. (6) Include any sample data that might have been unintentionally omitted in the original BBI and remove any sample data that should not have been included. (7) Sample data to be used in the BBI must be available on TWINS. (8) Ensure that an inventory value is provided for each waste component. Sample based inventories for new supplemental BBI analytes are to be included when available. (9) Provide new means and confidence interval reports if one is not already available and include uncertainties in reporting inventory values

    This document forms part of a suite of documents describing the Nirex model development programme. The programme is designed to provide a clear audit trail from the identification of significant features, events and processes (FEPs) to the models and modelling processes employed within a detailed safety assessment. A five stage approach has been adopted, which provides a systematic framework for addressing uncertainty and for the documentation of all modelling decisions and assumptions. The five stages are as follows: Stage 1: EP analysis - compilation and structuring of a FEP database; Stage 2: Scenario and conceptual model development; Stage 3: mathematical model development; Stage 4: Software development; Stage 5: confidence building. This report describes the work involved in Stage 1 of the Nirex model development programme, FEP analysis. The aim of FEP analysis is to produce a set of FEPs and FEP interactions that form the basis for the scenario and conceptual model development in Stage 2. There are two requirements for the set of FEPs and FEP interactions; first, all aspects material to the performance of the disposal system should be covered, i.e. the set should be comprehensive, and secondly a clear audit trail of decisions, consensus and analysis should be maintained

    To explore the efficacy of the revised Atlanta classification (RACAP) and the determinant-based classification of acute pancreatitis severity (DBCAPS) on the basis of clinical data and feedback from patients with acute pancreatitis (AP). The authors retrospectively investigated a total of 573 patients with AP admitted to our hospital between December 2011 and December 2014. The definitions of severity and local complications in AP using RACAP and DBCAPS are presented and common points and mutual differences between the 2 groups are analyzed and discussed. Classification according to RACAP and DBCAPS found 86 (15%) and 178 (31.1%) mild cases (P peripancreatic fluid collection (236 patients, 75.40%), pancreatic pseudocysts (20 patients, 6.4%), acute necrotic collection (42 patients, 13.4%), and walled-off necrosis (15 patients, 4.8%) were observed. Among the 153 DBCAPS-defined cases, sterile peripancreatic necrosis (105 patients, 68.6%), sterile pancreatic necrosis (44 patients, 28.8%), infected peripancreatic necrosis (2 patients, 1.3%), and infected pancreatic necrosis (2/153 patients, 1.3%) were observed. Both classifications adopted organ failure and complications as determinants of severity. Revised Atlanta classification refined local complications and DBCAPS modified severity to include critical AP. In accordance with the demands of precision medicine, a combination of the 2 could be important for further clinical practice and scientific research. PMID:26632905

  13. The basis for the strengthening of safeguards

    International Nuclear Information System (INIS)

    For the past 30 years, the International Atomic Energy Agency's safeguards system has contributed to the international non-proliferation regime, by providing, inter alia, assurances regarding the peaceful uses of declared nuclear material. However, the discovery of a clandestine nuclear weapons programme in Iraq in 1991 drew world-wide attention to the need to strengthen the system to address the absence of undeclared nuclear material and activities. Efforts to strengthen the IAEA's safeguards system began in 1991 and culminated in 1997 when the IAEA's Board of Governors approved a Model Protocol Additional to IAEA Safeguards Agreements which greatly expands the legal basis and scope of IAEA safeguards. Within this strengthened system it is expected that the IAEA be able to provide assurance not only of the absence of diversion of declared nuclear material but also on the absence of undeclared nuclear material and activities. This is to be done within a safeguards system that uses an optimal combination of all safeguards measures available, thereby achieving maximum effectiveness and efficiency within the available resources. This paper will summarize the evolution of the safeguards system, describe strengthened safeguards, report on the status of implementing the strengthening measures, and outline plans for integrating all available safeguards measures.

  14. Medical basis for radiation accident preparedness

    International Nuclear Information System (INIS)

    The International Conference on The Medical Basis for Radiation Accident Preparedness was organized by the staff of the Radiation Emergency Assistance Center/Training Site (REAC/TS) of the Medical and Health Sciences Division of Oak Ridge Associated Universities (ORAU). The philosophical importance of relating, through investigation and education, the intellectual resources of higher education to the important social problems associated with energy, health, and the environment was the foundation of the meeting. The symposium, held under the auspices of the US Department of Energy, was the ninth since 1960 of a series of international conferences addressing the various aspects of radiation accidents. The approach of this most recent conference differed somewhat from that of those preceding it, in that it sought an international review of the gamut of the medical aspects of radiation injury, not only for the experts in the field, but also for other physicians and scientists who, in view of current events, have had the need to know thrust upon them. Individual entries were made for the separate papers

  15. The genetic basis of chronic mountain sickness.

    2014-11-01

    Chronic mountain sickness (CMS) is a disease that affects many high-altitude dwellers, particularly in the Andean Mountains in South America. The hallmark symptom of CMS is polycythemia, which causes increased risk of pulmonary hypertension and stroke (among other symptoms). A prevailing hypothesis in high-altitude medicine is that CMS results from a population-specific "maladaptation" to the hypoxic conditions at high altitude. In contrast, the prevalence of CMS is very low in other high-altitude populations (e.g., Tibetans and Ethiopians), which are seemingly well adapted to hypoxia. In recent years, concurrent with the advent of genomic technologies, several studies have investigated the genetic basis of adaptation to altitude. These studies have identified several candidate genes that may underlie the adaptation, or maladaptation. Interestingly, some of these genes are targeted by known drugs, raising the possibility of new treatments for CMS and other ischemic diseases. We review recent discoveries, alongside the methodologies used to obtain them, and outline some of the challenges remaining in the field. PMID:25362634

  16. Cellular basis of memory for addiction.

    Nestler, Eric J

    2013-12-01

    DESPITE THE IMPORTANCE OF NUMEROUS PSYCHOSOCIAL FACTORS, AT ITS CORE, DRUG ADDICTION INVOLVES A BIOLOGICAL PROCESS: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. Here, we review the types of molecular and cellular adaptations that occur in specific brain regions to mediate addiction-associated behavioral abnormalities. These include alterations in gene expression achieved in part via epigenetic mechanisms, plasticity in the neurophysiological functioning of neurons and synapses, and associated plasticity in neuronal and synaptic morphology mediated in part by altered neurotrophic factor signaling. Each of these types of drug-induced modifications can be viewed as a form of "cellular or molecular memory." Moreover, it is striking that most addiction-related forms of plasticity are very similar to the types of plasticity that have been associated with more classic forms of "behavioral memory," perhaps reflecting the finite repertoire of adaptive mechanisms available to neurons when faced with environmental challenges. Finally, addiction-related molecular and cellular adaptations involve most of the same brain regions that mediate more classic forms of memory, consistent with the view that abnormal memories are important drivers of addiction syndromes. The goal of these studies which aim to explicate the molecular and cellular basis of drug addiction is to eventually develop biologically based diagnostic tests, as well as more effective treatments for addiction disorders.

    Spontaneous imitation is assumed to underlie the acquisition of important skills by infants, including language and social interaction. In this study, functional magnetic resonance imaging (fMRI) was used to examine the neural basis of 'spontaneously' driven imitation, which has not yet been fully investigated. Healthy participants were presented with movie clips of meaningless bimanual actions and instructed to observe and imitate them during an fMRI scan. The participants were subsequently shown the movie clips again and asked to evaluate the strength of their 'urge to imitate' (Urge) for each action. We searched for cortical areas where the degree of activation positively correlated with Urge scores; significant positive correlations were observed in the right supplementary motor area (SMA) and bilateral midcingulate cortex (MCC) under the imitation condition. These areas were not explained by explicit reasons for imitation or the kinematic characteristics of the actions. Previous studies performed in monkeys and humans have implicated the SMA and MCC/caudal cingulate zone in voluntary actions. This study also confirmed the functional connectivity between Urge and imitation performance using a psychophysiological interaction analysis. Thus, our findings reveal the critical neural components that underlie spontaneous imitation and provide possible reasons why infants imitate spontaneously. PMID:26168793

    Inhibition of kynurenine 3-monooxygenase (KMO), an enzyme in the eukaryotic tryptophan catabolic pathway (that is, kynurenine pathway), leads to amelioration of Huntington's-disease-relevant phenotypes in yeast, fruitfly and mouse models, as well as in a mouse model of Alzheimer's disease. KMO is a flavin adenine dinucleotide (FAD)-dependent monooxygenase and is located in the outer mitochondrial membrane where it converts l-kynurenine to 3-hydroxykynurenine. Perturbations in the levels of kynurenine pathway metabolites have been linked to the pathogenesis of a spectrum of brain disorders, as well as cancer and several peripheral inflammatory conditions. Despite the importance of KMO as a target for neurodegenerative disease, the molecular basis of KMO inhibition by available lead compounds has remained unknown. Here we report the first crystal structure of Saccharomyces cerevisiae KMO, in the free form and in complex with the tight-binding inhibitor UPF 648. UPF 648 binds close to the FAD cofactor and perturbs the local active-site structure, preventing productive binding of the substrate l-kynurenine. Functional assays and targeted mutagenesis reveal that the active-site architecture and UPF 648 binding are essentially identical in human KMO, validating the yeast KMO-UPF 648 structure as a template for structure-based drug design. This will inform the search for new KMO inhibitors that are able to cross the blood-brain barrier in targeted therapies against neurodegenerative diseases such as Huntington's, Alzheimer's and Parkinson's diseases.

  19. Electromagnetic Basis of Metabolism and Heredity

    Freund, Friedemann; Stolc, Viktor

    2016-01-01

    Living organisms control their cellular biological clocks to maintain functional oscillation of the redox cycle, also called the "metabolic cycle" or "respiratory cycle". Organization of cellular processes requires parallel processing on a synchronized time-base. These clocks coordinate the timing of all biochemical processes in the cell, including energy production, DNA replication, and RNA transcription. When this universal time keeping function is perturbed by exogenous induction of reactive oxygen species (ROS), the rate of metabolism changes. This causes oxidative stress, aging and mutations. Therefore, good temporal coordination of the redox cycle not only actively prevents chemical conflict between the reductive and oxidative partial reactions; it also maintains genome integrity and lifespan. Moreover, this universal biochemical rhythm can be disrupted by ROS induction in vivo. This in turn can be achieved by blocking the electron transport chain either endogenously or exogenously by various metabolites, e.g. hydrogen sulfide (H2S), highly diffusible drugs, and carbon monoxide (CO). Alternatively, the electron transport in vivo can be attenuated via a coherent or interfering transfer of energy from exogenous ultralow frequency (ULF) and extremely low frequency (ELF) electromagnetic (EM) fields, suggesting that-on Earth-such ambient fields are an omnipresent (and probably crucially important) factor for the time-setting basis of universal biochemical reactions in living cells. Our work demonstrated previously un-described evidence for quantum effects in biology by electromagnetic coupling below thermal noise at the universal electron transport chain (ETC) in vivo.

  20. Structural basis for spectrin recognition by ankyrin

    Energy Technology Data Exchange (ETDEWEB)

    Ipsaro, Jonathan J.; Mondragón, Alfonso (NWU)

    2010-10-19

    Maintenance of membrane integrity and organization in the metazoan cell is accomplished through intracellular tethering of membrane proteins to an extensive, flexible protein network. Spectrin, the principal component of this network, is anchored to membrane proteins through the adaptor protein ankyrin. To elucidate the atomic basis for this interaction, we determined a crystal structure of human {beta}I-spectrin repeats 13 to 15 in complex with the ZU5-ANK domain of human ankyrin R. The structure reveals the role of repeats 14 to 15 in binding, the electrostatic and hydrophobic contributions along the interface, and the necessity for a particular orientation of the spectrin repeats. Using structural and biochemical data as a guide, we characterized the individual proteins and their interactions by binding and thermal stability analyses. In addition to validating the structural model, these data provide insight into the nature of some mutations associated with cell morphology defects, including those found in human diseases such as hereditary spherocytosis and elliptocytosis. Finally, analysis of the ZU5 domain suggests it is a versatile protein-protein interaction module with distinct interaction surfaces. The structure represents not only the first of a spectrin fragment in complex with its binding partner, but also that of an intermolecular complex involving a ZU5 domain.

  1. Lack of design basis - An engineering affliction

    International Nuclear Information System (INIS)

    The intent of this paper is to present Pennsylvania Power and Light (PP and L) Company's progressive and investigative pursuit to uncover the underlying common factors and root causes behind the resolution of selected engineering issues, which were considered inconsistent with PP and L's standards of excellence, and the subsequent initiation of a formal design basis documentation project for the two-unit Susquehanna steam electric station. The nuclear department of PP and L has consistently exhibited an exceptional record regarding the resolution of significant issues related to the design and operation of Susquehanna. This culture is best described in its commitment to the department mission statement to operate, maintain, and support Susquehanna such that the station reliably and efficiently generates the maximum amount of power without compromising public or employee safety. In its pursuit to maintain excellence, PP and L initiated the root-cause analysis project, which focused on the ability of the PP and L nuclear department to address engineering issues in a timely manner. The objective of this effort was to test the department's effectiveness in timely evaluation and resolution of specific engineering issues through the use of root-cause analysis techniques

  3. Accelerated Best Basis Inventory Baselining Task

    International Nuclear Information System (INIS)

    The baselining effort was recently proposed to bring the Best-Basis Inventory (BBI) and Question No.8 of the Tank Interpretive Report (TIR) for all 177 tanks to the current standards and protocols and to prepare a TIR Question No.8 if one is not already available. This plan outlines the objectives and methodology of the accelerated BBI baselining task. BBI baselining meetings held during December 2000 resulted in a revised BBI methodology and an initial set of BBI creation rules to be used in the baselining effort. The objectives of the BBI baselining effort are to: (1) Provide inventories that are consistent with the revised BBI methodology and new BBI creation rules. (2) Split the total tank waste in each tank into six waste phases, as appropriate (Supernatant, saltcake solids, saltcake liquid, sludge solids, sludge liquid, and retained gas). In some tanks, the solids and liquid portions of the sludge and/or saltcake may be combined into a single sludge or saltcake phase. (3) Identify sampling events that are to be used for calculating the BBIs. (4) Update waste volumes for subsequent reconciliation with the Hanlon (2001) waste tank summary. (5) Implement new waste type templates. (6) Include any sample data that might have been unintentionally omitted in the previous BBI and remove any sample data that should not have been included. Sample data to be used in the BBI must be available on TWINS. (7) Ensure that an inventory value for each standard BBI analyte is provided for each waste component. Sample based inventories for supplemental BBI analytes will be included when available. (8) Provide new means and confidence interval reports if one is not already available and include uncertainties in reporting inventory values

    The success of gas reactors depends upon the safety and quality of the coated particle fuel. The fuel performance modeling code PARFUME simulates the mechanical, thermal and physico-chemical behavior of fuel particles during irradiation. This report documents the theory and material properties behind vari¬ous capabilities of the code, which include: 1) various options for calculating CO production and fission product gas release, 2) an analytical solution for stresses in the coating layers that accounts for irradiation-induced creep and swelling of the pyrocarbon layers, 3) a thermal model that calculates a time-dependent temperature profile through a pebble bed sphere or a prismatic block core, as well as through the layers of each analyzed particle, 4) simulation of multi-dimensional particle behavior associated with cracking in the IPyC layer, partial debonding of the IPyC from the SiC, particle asphericity, and kernel migration (or amoeba effect), 5) two independent methods for determining particle failure probabilities, 6) a model for calculating release-to-birth (R/B) ratios of gaseous fission products that accounts for particle failures and uranium contamination in the fuel matrix, and 7) the evaluation of an accident condition, where a particle experiences a sudden change in temperature following a period of normal irradiation. The accident condi¬tion entails diffusion of fission products through the particle coating layers and through the fuel matrix to the coolant boundary. This document represents the initial version of the PARFUME Theory and Model Basis Report. More detailed descriptions will be provided in future revisions.

  5. Entanglement patterns in mutually unbiased basis sets

    International Nuclear Information System (INIS)

    A few simply stated rules govern the entanglement patterns that can occur in mutually unbiased basis sets (MUBs) and constrain the combinations of such patterns that can coexist in full complements of MUBs. We consider Hilbert spaces of prime power dimensions (D=pN), as realized by systems of N prime-state particles, where full complements of D+1 MUBs are known to exist, and we assume only that MUBs are eigenbases of generalized Pauli operators, without using any particular construction. The general rules include the following: (1) In any MUB, a given particle appears either in a pure state or totally entangled and (2) in any full MUB complement, each particle is pure in (p+1) bases (not necessarily the same ones) and totally entangled in the remaining (pN-p). It follows that the maximum number of product bases is p+1 and, when this number is realized, all remaining (pN-p) bases in the complement are characterized by the total entanglement of every particle. This ''standard distribution'' is inescapable for two-particle systems (of any p), where only product and generalized Bell bases are admissible MUB types. This and the following results generalize previous results for qubits [Phys. Rev. A 65. 032320 (2002); Phys. Rev. A 72, 062310 (2005)] and qutrits [Phys. Rev. A 70, 012302 (2004)], drawing particularly upon [Phys. Rev. A 72, 062310 (2005)]. With three particles there are three MUB types, and these may be combined in (p+2) different ways to form full complements. With N=4, there are 6 MUB types for p=2, but new MUB types become possible with larger p, and these are essential to realizing full complements. With this example, we argue that new MUB types that show new entanglement patterns should enter with every step in N and, also, when N is a prime plus 1, at a critical p value, p=N-1. Such MUBs should play critical roles in filling complements.

  12. The neural circuit basis of learning

    Science.gov (United States)

    Patrick, Kaifosh William John

    The astounding capacity for learning ranks among the nervous system's most impressive features. This thesis comprises studies employing varied approaches to improve understanding, at the level of neural circuits, of the brain's capacity for learning. The first part of the thesis contains investigations of hippocampal circuitry -- both theoretical work and experimental work in the mouse Mus musculus -- as a model system for declarative memory. To begin, Chapter 2 presents a theory of hippocampal memory storage and retrieval that reflects nonlinear dendritic processing within hippocampal pyramidal neurons. As a prelude to the experimental work that comprises the remainder of this part, Chapter 3 describes an open source software platform that we have developed for analysis of data acquired with in vivo Ca2+ imaging, the main experimental technique used throughout the remainder of this part of the thesis. As a first application of this technique, Chapter 4 characterizes the content of signaling at synapses between GABAergic neurons of the medial septum and interneurons in stratum oriens of hippocampal area CA1. Chapter 5 then combines these techniques with optogenetic, pharmacogenetic, and pharmacological manipulations to uncover inhibitory circuit mechanisms underlying fear learning. The second part of this thesis focuses on the cerebellum-like electrosensory lobe in the weakly electric mormyrid fish Gnathonemus petersii, as a model system for non-declarative memory. In Chapter 6, we study how short-duration EOD motor commands are recoded into a complex temporal basis in the granule cell layer, which can be used to cancel Purkinje-like cell firing to the longer duration and temporally varying EOD-driven sensory responses. In Chapter 7, we consider not only the temporal aspects of the granule cell code, but also the encoding of body position provided from proprioceptive and efference copy sources. Together these studies clarify how the cerebellum-like circuitry of the

    Full Text Available Bounded rational behaviour is commonly observed in experimental games and in real life situations. Neuroeconomics can help to understand the mental processing underlying bounded rationality and out-of-equilibrium behaviour. Here we report results from recent studies on the neural basis of limited steps of reasoning in a competitive setting —the beauty contest game. We use functional magnetic resonance imaging (fMRI to study the neural correlates of human mental processes in strategic games. We apply a cognitive hierarchy model to classify subject’s choices in the experimental game according to the degree of strategic reasoning so that we can identify the neural substrates of different levels of strategizing. We found a correlation between levels of strategic reasoning and activity in a neural network related to mentalizing, i.e. the ability to think about other’s thoughts and mental states. Moreover, brain data showed how complex cognitive processes subserve the higher level of reasoning about others. We describe how a cognitive hierarchy model fits both behavioural and brain data.

    A simple yet general method for constructing basis sets for molecular electronic structure calculations is presented. These basis sets consist of atomic natural orbitals from a multi-configurational self-consistent field calculation supplemented with primitive functions, chosen such that the asymptotics are appropriate for the potential of the system.

  15. Property-optimized Gaussian basis sets for molecular response calculations

    Science.gov (United States)

    Rappoport, Dmitrij; Furche, Filipp

    2010-10-01

    With recent advances in electronic structure methods, first-principles calculations of electronic response properties, such as linear and nonlinear polarizabilities, have become possible for molecules with more than 100 atoms. Basis set incompleteness is typically the main source of error in such calculations since traditional diffuse augmented basis sets are too costly to use or suffer from near linear dependence. To address this problem, we construct the first comprehensive set of property-optimized augmented basis sets for elements H-Rn except lanthanides. The new basis sets build on the Karlsruhe segmented contracted basis sets of split-valence to quadruple-zeta valence quality and add a small number of moderately diffuse basis functions. The exponents are determined variationally by maximization of atomic Hartree-Fock polarizabilities using analytical derivative methods. The performance of the resulting basis sets is assessed using a set of 313 molecular static Hartree-Fock polarizabilities. The mean absolute basis set errors are 3.6%, 1.1%, and 0.3% for property-optimized basis sets of split-valence, triple-zeta, and quadruple-zeta valence quality, respectively. Density functional and second-order Møller-Plesset polarizabilities show similar basis set convergence. We demonstrate the efficiency of our basis sets by computing static polarizabilities of icosahedral fullerenes up to C720 using hybrid density functional theory.

  16. Optimized Basis Sets for the Environment in the Domain-Specific Basis Set Approach of the Incremental Scheme.

    Science.gov (United States)

    Anacker, Tony; Hill, J Grant; Friedrich, Joachim

    2016-04-21

    Minimal basis sets, denoted DSBSenv, based on the segmented basis sets of Ahlrichs and co-workers have been developed for use as environmental basis sets for the domain-specific basis set (DSBS) incremental scheme with the aim of decreasing the CPU requirements of the incremental scheme. The use of these minimal basis sets within explicitly correlated (F12) methods has been enabled by the optimization of matching auxiliary basis sets for use in density fitting of two-electron integrals and resolution of the identity. The accuracy of these auxiliary sets has been validated by calculations on a test set containing small- to medium-sized molecules. The errors due to density fitting are about 2-4 orders of magnitude smaller than the basis set incompleteness error of the DSBSenv orbital basis sets. Additional reductions in computational cost have been tested with the reduced DSBSenv basis sets, in which the highest angular momentum functions of the DSBSenv auxiliary basis sets have been removed. The optimized and reduced basis sets are used in the framework of the domain-specific basis set of the incremental scheme to decrease the computation time without significant loss of accuracy. The computation times and accuracy of the previously used environmental basis and that optimized in this work have been validated with a test set of medium- to large-sized systems. The optimized and reduced DSBSenv basis sets decrease the CPU time by about 15.4% and 19.4% compared with the old environmental basis and retain the accuracy in the absolute energy with standard deviations of 0.99 and 1.06 kJ/mol, respectively.

  17. Design basis reconstitution for an effective design control program

    International Nuclear Information System (INIS)

    Configuration management is a new buzz word in the nuclear power industry. Whatever its definition, everyone agrees that the configuration of a nuclear power plant must be managed effectively. In layman's terms, configuration management means that a plant must be built, operated, and maintained in a manner consistent with its design basis. Thus, control of the design basis is the most important element in any configuration management program. Until recently, the US Nuclear Regulatory Commission's (NRC's) review of design basis focused on the plants that were about to get operating licenses. However, incidents at a few operating nuclear plants and NRC inspections (Safety System Functional Inspection and Safety System Outage Modification Inspection) have indicated weaknesses in older operating plant design basis documentation and design change control programs. Thus, reconstitution of plant design basis has become an important issue. This paper presents the major element of a design basis reconstitution program, which can be an immense undertaking for some of the older operating plants

    The optimal estimation of a quantum mechanical 2-state system (qubit) - with N identically prepared qubits available - is obtained by measuring all qubits simultaneously in an entangled basis. We report the experimental estimation of qubits using a succession of N measurements on individual qubits where the measurement basis is changed during the estimation procedure conditioned on the outcome of previous measurements (self-learning estimation). The performance of this adaptive algorithm is compared with other algorithms using measurements in a factorizing basis.

    1993-01-01

    We show that the Hilbert space basis that defines the Ponzano-Regge- Turaev-Viro-Ooguri combinatorial definition of 3-d Quantum Gravity is the same as the one that defines the Loop Representation. We show how to compute lengths in Witten's 3-d gravity and how to reconstruct the 2-d geometry from a state of Witten's theory. We show that the non-degenerate geometries are contained in the Witten's Hilbert space. We sketch an extension of the combinatorial construction to the physical 4-d case, by defining a modification of Regge calculus in which areas, rather than lengths, are taken as independent variables. We provide an expression for the scalar product in the Loop representation in 4-d. We discuss the general form of a nonperturbative quantum theory of gravity, and argue that it should be given by a generalization of Atiyah's topological quantum field theories axioms.

    We describe how to create ab-initio effective Hamiltonians that qualitatively describe correct chemistry even when used with a minimal basis. The Hamiltonians are obtained by folding correlation down from a large parent basis into a small, or minimal, target basis, using the machinery of canonical transformations. We demonstrate the quality of these effective Hamiltonians to correctly capture a wide range of excited states in water, nitrogen, and ethylene, and to describe ground and excited state bond-breaking in nitrogen and the chromium dimer, all in small or minimal basis sets.

Avaliou-se a ocorrência de bactérias clinicamente relevantes na pilha de resíduos de serviços de saúde em um aterro sanitário e seu perfil de susceptibilidade aos antimicrobianos. Alíquotas de chorume foram processadas para isolamento seletivo de Staphylococcus sp, bastonetes Gram negativos da família Enterobacteriaceae e não fermentadores. Resistência bacteriana a todos os antimicrobianos testados foi observada em todos os grupos microbianos, além de resistência a mais de uma droga. Os resultados permitem sugerir que bactérias viáveis nos resíduos de serviços de saúde representam riscos à saúde humana e animal. Além disso, a ocorrência de linhagens multirresistentes sustenta a hipótese dos resíduos de serviços de saúde atuarem como reservatórios de marcadores de resistência, com impacto ambiental. A falta de legislação regional de segregação, tratamento e destino de resíduos podem expor diferentes populações a riscos de transmissão de doenças infecciosas associadas a microrganismos multirresistentes.Health service waste gives rise to controversy regarding its importance for human, animal and environmental health.

Bacterial resistance to all the antimicrobials tested was observed in all microbial groups, including resistance to more than one drug. The results make it possible to suggest that viable bacteria in health service waste represent risks to human and animal health.

    Science.gov (United States)

    Nikolaev, A. V.; Lamoen, D.; Partoens, B.

    2016-07-01

    In order to increase the accuracy of the linearized augmented plane wave (LAPW) method, we present a new approach where the plane wave basis function is augmented by two different atomic radial components constructed at two different linearization energies corresponding to two different electron bands (or energy windows). We demonstrate that this case can be reduced to the standard treatment within the LAPW paradigm where the usual basis set is enriched by the basis functions of the tight binding type, which go to zero with zero derivative at the sphere boundary. We show that the task is closely related with the problem of extended core states which is currently solved by applying the LAPW method with local orbitals (LAPW+LO). In comparison with LAPW+LO, the number of supplemented basis functions in our approach is doubled, which opens up a new channel for the extension of the LAPW and LAPW+LO basis sets. The appearance of new supplemented basis functions absent in the LAPW+LO treatment is closely related with the existence of the u ˙ l -component in the canonical LAPW method. We discuss properties of additional tight binding basis functions and apply the extended basis set for computation of electron energy bands of lanthanum (face and body centered structures) and hexagonal close packed lattice of cadmium. We demonstrate that the new treatment gives lower total energies in comparison with both canonical LAPW and LAPW+LO, with the energy difference more pronounced for intermediate and poor LAPW basis sets.

  10. TreeBASIS Feature Descriptor and Its Hardware Implementation

    Directory of Open Access Journals (Sweden)

    Spencer Fowers

    2014-01-01

    Full Text Available This paper presents a novel feature descriptor called TreeBASIS that provides improvements in descriptor size, computation time, matching speed, and accuracy. This new descriptor uses a binary vocabulary tree that is computed using basis dictionary images and a test set of feature region images. To facilitate real-time implementation, a feature region image is binary quantized and the resulting quantized vector is passed into the BASIS vocabulary tree. A Hamming distance is then computed between the feature region image and the effectively descriptive basis dictionary image at a node to determine the branch taken and the path the feature region image takes is saved as a descriptor. The TreeBASIS feature descriptor is an excellent candidate for hardware implementation because of its reduced descriptor size and the fact that descriptors can be created and features matched without the use of floating point operations. The TreeBASIS descriptor is more computationally and space efficient than other descriptors such as BASIS, SIFT, and SURF. Moreover, it can be computed entirely in hardware without the support of a CPU for additional software-based computations. Experimental results and a hardware implementation show that the TreeBASIS descriptor compares well with other descriptors for frame-to-frame homography computation while requiring fewer hardware resources.

    Glickman, Yinnon; Kotler, Shlomi; Akerman, Nitzan; Ozeri, Roee

    2013-03-01

    After measurement, a wave-function is postulated to collapse on a predetermined set of states--the measurement basis. Using quantum process tomography, we show how a measurement basis emerges in the evolution of the electronic spin of a single trapped atomic ion after spontaneous photon scattering and detection. This basis is determined by the excitation laser polarization and the direction along which the photon was detected. Quantum tomography of the combined spin-photon state reveals that although photon scattering entangles all superpositions of the measurement-basis states with the scattered photon polarization, the measurement-basis states themselves remain classically correlated with it. Our findings shed light on the process of quantum measurement in atom-photon interactions. PMID:23471403

  16. Exploring continuum structures with a pseudo-state basis

    International Nuclear Information System (INIS)

    The ability of a recently developed square-integrable discrete basis to represent the properties of the continuum of a two-body system is investigated. The basis is obtained performing a simple analytic local scale transformation to the harmonic oscillator basis. Scattering phase-shifts and the electric transition probabilities B(E1) and B(E2) have been evaluated for several potentials using the proposed basis. Both quantities are found to be in excellent agreement with the exact values calculated from the true scattering states. The basis has been applied to describe the projectile continuum in the 6He scattering by 12C and 208Pb targets at 240 MeV/nucleon and the 11Be scattering by 12C at 67 MeV/nucleon. The calculated breakup differential cross sections are found to be in very good agreement with the available experimental data for these reactions.

    Solid wastes must be managed to prevent inadvertent reactions, explosion and degradation of waste containers per the ''Washington State Department of Ecology Dangerous Waste Regulations'' (WAC 173-303). An understanding of chemical compatibility principles and a consistent approach for implementing compatibility requirements is essential for complying with the regulations. This document explains the technical basis for ensuring chemical compatibility for solid wastes that are stored on site at on-site TSD facilities and for solid waste that will go to off-site TSD facilities. The document applies directly to the following aspects of chemical compatibility: (1) Ensuring that hazardous waste is not chemically reactive or unstable such that it cannot be safely transported or stored; (2) Ensuring that lab packs (i.e., drums containing multiple inner containers of differing types of hazardous waste) are packaged such that incompatible chemicals are not placed into the same drum; (3) Selecting containers and liners that are compatible with the waste they contain. This document does not cover individual TSD requirements, or specific offsite TSD requirements. This document does not cover chemical compatibility and segregation requirements for shipping wastes on-site or off-site. This document does not cover radiological hazards associated with radioactive waste or mixed wastes. Evaluation of compatibility for comingling and treating solid waste is beyond the scope of this document. In addition, heat generation and gas generation as they apply to the Hanford waste acceptance criteria are not covered in this document

    The poly(ADP-ribose)polymerases Tankyrase 1/2 (TNKS/TNKS2) catalyze the covalent linkage of ADP-ribose polymer chains onto target proteins, regulating their ubiquitylation, stability, and function. Dysregulation of substrate recognition by Tankyrases underlies the human disease cherubism. Tankyrases recruit specific motifs (often called RxxPDG hexapeptides) in their substrates via an N-terminal region of ankyrin repeats. These ankyrin repeats form five domains termed ankyrin repeat clusters (ARCs), each predicted to bind substrate. Here we report crystal structures of a representative ARC of TNKS2 bound to targeting peptides from six substrates. Using a solution-based peptide library screen, we derive a rule-based consensus for Tankyrase substrates common to four functionally conserved ARCs. This 8-residue consensus allows us to rationalize all known Tankyrase substrates and explains the basis for cherubism-causing mutations in the Tankyrase substrate 3BP2. Structural and sequence information allows us to also predict and validate other Tankyrase targets, including Disc1, Striatin, Fat4, RAD54, BCR, and MERIT40.

  20. Finite basis representations with nondirect product basis functions having structure similar to that of spherical harmonics

    Science.gov (United States)

    Czakó, Gábor; Szalay, Viktor; Császár, Attila G.

    2006-01-01

    The currently most efficient finite basis representation (FBR) method [Corey et al., in Numerical Grid Methods and Their Applications to Schrödinger Equation, NATO ASI Series C, edited by C. Cerjan (Kluwer Academic, New York, 1993), Vol. 412, p. 1; Bramley et al., J. Chem. Phys. 100, 6175 (1994)] designed specifically to deal with nondirect product bases of structures ϕnl(s)fl(u), χml(t)ϕnl(s)fl(u), etc., employs very special l-independent grids and results in a symmetric FBR. While highly efficient, this method is not general enough. For instance, it cannot deal with nondirect product bases of the above structure efficiently if the functions ϕnl(s) [and/or χml(t)] are discrete variable representation (DVR) functions of the infinite type. The optimal-generalized FBR(DVR) method [V. Szalay, J. Chem. Phys. 105, 6940 (1996)] is designed to deal with general, i.e., direct and/or nondirect product, bases and grids. This robust method, however, is too general, and its direct application can result in inefficient computer codes [Czakó et al., J. Chem. Phys. 122, 024101 (2005)]. It is shown here how the optimal-generalized FBR method can be simplified in the case of nondirect product bases of structures ϕnl(s)fl(u), χml(t)ϕnl(s)fl(u), etc. As a result the commonly used symmetric FBR is recovered and simplified nonsymmetric FBRs utilizing very special l-dependent grids are obtained. The nonsymmetric FBRs are more general than the symmetric FBR in that they can be employed efficiently even when the functions ϕnl(s) [and/or χml(t)] are DVR functions of the infinite type. Arithmetic operation counts and a simple numerical example presented show unambiguously that setting up the Hamiltonian matrix requires significantly less computer time when using one of the proposed nonsymmetric FBRs than that in the symmetric FBR. Therefore, application of this nonsymmetric FBR is more efficient than that of the symmetric FBR when one wants to diagonalize the Hamiltonian matrix

  1. Wavelet basis construction method based on separation blast vibration signal

    2015-01-01

    As wavelet basis in wavelet analysis is neither arbitrary nor unique, the same signal dealing with different wavelet bases will generate different results. Therefore, how to construct a wavelet basis suitable for the characteristics of the analyzed signal and solve its algorithm and realization is a fundamental problem which perplexed many researchers. To solve these problems, in accordance with the basic features of the measured millisecond blast vibration signal, a new wavelet basis construction method based on the separation blast vibration signal is proposed, and the feasibility of this method is verified by comparing the practical effect of the newly constructed wavelet with other known wavelets in signal processing.

  3. Exploring {{W}}_{∞ } in the quadratic basis

    Procházka, Tomáš

    2015-09-01

    We study the operator product expansions in the chiral algebra {W}_{∞ } , first using the associativity conditions in the basis of primary generating fields and then using a different basis coming from the free field representation in which the OPE takes a simpler quadratic form. The results in the quadratic basis can be compactly written using certain bilocal combinations of the generating fields and we conjecture a closed-form expression for the complete OPE in this basis. Next we show that the commutation relations as well as correlation functions can be easily computed using properties of these bilocal fields. In the last part we verify the consistency with results derived previously by studying minimal models of {W}_{∞ } and comparing them to known reductions of {W}_{∞ } to {W}_N . The results we obtain illustrate nicely the role of triality symmetry in the representation theory of {W}_{∞ }.

  11. Basis for breakup states of three identical particles

    International Nuclear Information System (INIS)

    A new basis for expanding three-body momentum-space states for three identical particles is studied. The basis states are simultaneously eigenstates of the total angular momentum and the total antisymmetrization operator. The total kinetic energy and two Dalitz-Fabri variables are chosen as the remaining three continuous variables. Zernike polynomials are used as a basis set for a generalized Fourier expansion in the Dalitz-Fabri variables. Born approximations to the nucleon-deuteron breakup amplitude zero total orbital angular momentum) are calculated for Malfliet-Tjon I-III potentials and displayed in a Dalitz plot that shows the global structures of the reaction probabilities. Numerical results are presented, which indicate favorable convergence properties of the generalized Fourier expansion. These results suggest that the new basis set may be attractive in more realistic calculations. (author)

    The accident at the Fukushima Daiichi NPP highlighted the need for NPPs to be prepared for beyond design basis accidents. The equipment needed to respond to such beyond design basis accidents may include some non-safety-related equipment, which is outside the scope of the traditional PSR, LRA, maintenance rule, or other ageing management evaluation processes. Such non-safety-related equipment should also be subject to ageing management in order to ensure proper LTO functioning during the period of extended operation

    Petruzielo, F. R.; Toulouse, Julien; Umrigar, C. J.

    2011-02-01

    A simple yet general method for constructing basis sets for molecular electronic structure calculations is presented. These basis sets consist of atomic natural orbitals from a multiconfigurational self-consistent field calculation supplemented with primitive functions, chosen such that the asymptotics are appropriate for the potential of the system. Primitives are optimized for the homonuclear diatomic molecule to produce a balanced basis set. Two general features that facilitate this basis construction are demonstrated. First, weak coupling exists between the optimal exponents of primitives with different angular momenta. Second, the optimal primitive exponents for a chosen system depend weakly on the particular level of theory employed for optimization. The explicit case considered here is a basis set appropriate for the Burkatzki-Filippi-Dolg pseudopotentials. Since these pseudopotentials are finite at nuclei and have a Coulomb tail, the recently proposed Gauss-Slater functions are the appropriate primitives. Double- and triple-zeta bases are developed for elements hydrogen through argon. These new bases offer significant gains over the corresponding Burkatzki-Filippi-Dolg bases at various levels of theory. Using a Gaussian expansion of the basis functions, these bases can be employed in any electronic structure method. Quantum Monte Carlo provides an added benefit: expansions are unnecessary since the integrals are evaluated numerically.

  20. Preventive maintenance basis: Project overview report update. Final report

    International Nuclear Information System (INIS)

    Preventive maintenance (PM) programs in US nuclear plants have evolved from strict compliance with the vendor's general recommendations which are likely to be conservative, to more flexible tasks which are intended to accommodate the plant service conditions. These PM programs have evolved piecemeal from the vendor recommendations and historical experience, with the result that their logical structure and coherent basis may be technically weak and scarcely recognized. The historical reasons for the performance of specific PM tasks are usually poorly documented, if at all. The result is that relationships and dependencies between the tasks, their limits of applicability and justifications for task intervals, are not well known. Utilities have expressed the desire for a technical basis and rationale capable of supporting the maintenance tasks for each major component type and of facilitating appropriate changes to them. The PM Basis project provides the utility user with the technical basis for PM tasks and task intervals and also gives the necessary information to adapt the tasks and intervals to plant conditions. A recommended program of PM tasks, a synopsis of the task content and intervals, and the reasons why these choices are technically valid in a variety of circumstances, are presented for 39 major component types. Each component type is treated in a separate volume of this series. This project overview report presents the project objectives and organization, describes the content, interpretation, and use of the PM Basis database, and explains the process by which the information was obtained

  1. Efficient computation of smoothing splines via adaptive basis sampling

    KAUST Repository

    Ma, Ping

    2015-06-24

    © 2015 Biometrika Trust. Smoothing splines provide flexible nonparametric regression estimators. However, the high computational cost of smoothing splines for large datasets has hindered their wide application. In this article, we develop a new method, named adaptive basis sampling, for efficient computation of smoothing splines in super-large samples. Except for the univariate case where the Reinsch algorithm is applicable, a smoothing spline for a regression problem with sample size n can be expressed as a linear combination of n basis functions and its computational complexity is generally O(n3). We achieve a more scalable computation in the multivariate case by evaluating the smoothing spline using a smaller set of basis functions, obtained by an adaptive sampling scheme that uses values of the response variable. Our asymptotic analysis shows that smoothing splines computed via adaptive basis sampling converge to the true function at the same rate as full basis smoothing splines. Using simulation studies and a large-scale deep earth core-mantle boundary imaging study, we show that the proposed method outperforms a sampling method that does not use the values of response variables.

    2011-01-01

    Let $K$ be a simplicial complex and $g$ the rank of its $p$-th homology group $H_p(K)$ defined with $Z_2$ coefficients. We show that we can compute a basis $H$ of $H_p(K)$ and annotate each $p$-simplex of $K$ with a binary vector of length $g$ with the following property: the annotations, summed over all $p$-simplices in any $p$-cycle $z$, provide the coordinate vector of the homology class $[z]$ in the basis $H$. The basis and the annotations for all simplices can be computed in $O(n^{\\omega})$ time, where $n$ is the size of $K$ and $\\omega<2.376$ is a quantity so that two $n\\times n$ matrices can be multiplied in $O(n^{\\omega})$ time. The pre-computation of annotations permits answering queries about the independence or the triviality of $p$-cycles efficiently. Using annotations of edges in 2-complexes, we derive better algorithms for computing optimal basis and optimal homologous cycles in 1-dimensional homology. Specifically, for computing an optimal basis of $H_1(K)$, we improve the time complexity kn...

  3. Beyond design basis issues in the Russian Federation

    International Nuclear Information System (INIS)

    The primary reactor cooling system forms the third defence in depth physical barrier on the radioactive material propagation path to the environment. During normal and emergency conditions, the effectiveness of its function as a barrier depends on a wide range of internal processes including automatic and operator actions as well as external events impacting the plant. Within the bounds of NPP life extension, a Level 1 PSA is carried out to quantify the risk of a nuclear accident. The output of a Level 1 PSA is a severe accident frequency value corresponding to the probability that the reactor containment may be breached. A set of all the relevant initiating events and their combinations is built into the NPP design basis, therefore all safety analyses of the consequences of these events on the plant are performed in response to the licensing requirements. In a PSA, several types of analyses are performed, including probabilistic reliability analysis of all normal operating regimes, of design basis accidents and also of beyond design basis accidents caused by each type of initiating event, including (fire, flood and earthquake). Initiating events are events that either directly or indirectly cause damage to the reactor core, for example events that cause reactor core damage due to failure of the reactor safety system functions or to non-compliance with the safety and licensing requirements under design basis accidents, or events that cause severe accidents (beyond design basis), that produce catastrophic damage to the reactor core

    We find a construction that expresses any tree-level $n$-particle ${\\rm N^{k-2}MHV}$ color-ordered partial amplitude in gauge theory as a linear combination of a basis of dimension $\\eulerian{n-3}{k-2}$. Here $\\eulerian{p}{q}$ denotes the $(p,q)$ Eulerian number. The coefficients of the expansion are independent of the helicities of the particles. This basis is a four-dimensional refinement of the $(n-3)!$-element BCJ basis which is valid in any number of dimensions. The construction uses a new kind of objects which we call {\\it scalar blocks}. Here we initiate the study of these objects. Scalar blocks provide an "${\\rm N^{k-2}MHV}$ sector" decomposition of a bi-adjoint scalar amplitude in four dimensions. As byproducts of the construction, we also find an intrinsically four-dimensional version of KLT relations for gravity amplitudes.

  6. Development of design basis capacity for SNF project systems

    International Nuclear Information System (INIS)

    An estimate of the design capacity for Spent Nuclear Fuel Project systems producing Multi-Canister Overpacks is developed based on completing fuel processing in a two year period. The design basis capacity for systems relates the desired annual processing rate to potential operating inefficiencies which may be actually experienced to project a design capacity for systems. The basis for estimating operating efficiency factors is described. Estimates of the design basis capacity were limited to systems actually producing the Multi-Canister Overpack. These systems include Fuel Retrieval, K Basin SNF Vacuum Drying, Canister Storage Building support for Staging and Storage, and Hot Vacuum conditioning. The capacity of other systems are assumed to be derived from these system capacities such that systems producing a Multi-Canister Overpack are not constrained

  7. Point Set Denoising Using Bootstrap-Based Radial Basis Function

    Ramli, Ahmad; Abd. Majid, Ahmad

    2016-01-01

    This paper examines the application of a bootstrap test error estimation of radial basis functions, specifically thin-plate spline fitting, in surface smoothing. The presence of noisy data is a common issue of the point set model that is generated from 3D scanning devices, and hence, point set denoising is one of the main concerns in point set modelling. Bootstrap test error estimation, which is applied when searching for the smoothing parameters of radial basis functions, is revisited. The main contribution of this paper is a smoothing algorithm that relies on a bootstrap-based radial basis function. The proposed method incorporates a k-nearest neighbour search and then projects the point set to the approximated thin-plate spline surface. Therefore, the denoising process is achieved, and the features are well preserved. A comparison of the proposed method with other smoothing methods is also carried out in this study. PMID:27315105

  9. Initial evaluation of discrete orthogonal basis reconstruction of ECT images

    International Nuclear Information System (INIS)

    Discrete orthogonal basis restoration (DOBR) is a linear, non-iterative, and robust method for solving inverse problems for systems characterized by shift-variant transfer functions. This simulation study evaluates the feasibility of using DOBR for reconstructing emission computed tomographic (ECT) images. The imaging system model uses typical SPECT parameters and incorporates the effects of attenuation, spatially-variant PSF, and Poisson noise in the projection process. Sample reconstructions and statistical error analyses for a class of digital phantoms compare the DOBR performance for Hartley and Walsh basis functions. Test results confirm that DOBR with either basis set produces images with good statistical properties. No problems were encountered with reconstruction instability. The flexibility of the DOBR method and its consistent performance warrants further investigation of DOBR as a means of ECT image reconstruction

  10. Speech/Nonspeech Detection Using Minimal Walsh Basis Functions

    Directory of Open Access Journals (Sweden)

    Pwint Moe

    2007-01-01

    Full Text Available This paper presents a new method to detect speech/nonspeech components of a given noisy signal. Employing the combination of binary Walsh basis functions and an analysis-synthesis scheme, the original noisy speech signal is modified first. From the modified signals, the speech components are distinguished from the nonspeech components by using a simple decision scheme. Minimal number of Walsh basis functions to be applied is determined using singular value decomposition (SVD. The main advantages of the proposed method are low computational complexity, less parameters to be adjusted, and simple implementation. It is observed that the use of Walsh basis functions makes the proposed algorithm efficiently applicable in real-world situations where processing time is crucial. Simulation results indicate that the proposed algorithm achieves high-speech and nonspeech detection rates while maintaining a low error rate for different noisy conditions.

  11. SAFETY BASIS DESIGN DEVELOPMENT CHALLENGES IMECE2007-42747

    International Nuclear Information System (INIS)

    'Designing in Safety' is a desired part of the development of any new potentially hazardous system, process, or facility. It is a required part of nuclear safety activities as specified in the U.S. Department of Energy (DOE) Order 420.B, Facility Safety. This order addresses the design of nuclear related facilities developed under federal regulation IOCFR830, Nuclear Safety Management. IOCFR830 requires that safety basis documentation be provided to identify how nuclear safety is being adequately addressed as a condition for system operation (e.g., the safety basis). To support the development of the safety basis, a safety analysis is performed. Although the concept of developing a design that addresses 'Safety is simple, the execution can be complex and challenging. This paper addresses those complexities and challenges for the design activity of a system to treat sludge, a corrosion product of spent nuclear fuel, at DOE's Hanford Site in Washington State. The system being developed is referred to as the Sludge Treatment Project (STP). This paper describes the portion of the safety analysis that addresses the selection of design basis events using the experience gained from the STP and the development of design requirements for safety features associated with those events. Specifically, the paper describes the safety design process and the application of the process for two types of potential design basis accidents associated with the operation of the system, (1) flashing spray leaks and (2) splash and splatter leaks. Also presented are the technical challenges that are being addressed to develop effective safety features to deal with these design basis accidents

  12. PFP total process throughput calculation and basis of estimate

    International Nuclear Information System (INIS)

    The PFP Process Throughput Calculation and Basis of Estimate document provides the calculated value and basis of estimate for process throughput associated with material stabilization operations conducted in 234-52 Building. The process throughput data provided reflects the best estimates of material processing rates consistent with experience at the Plutonium Finishing Plant (PFP) and other U.S. Department of Energy (DOE) sites. The rates shown reflect demonstrated capacity during ''full'' operation. They do not reflect impacts of building down time. Therefore, these throughput rates need to have a Total Operating Efficiency (TOE) factor applied

    Science.gov (United States)

    Howard, Jonathon; Grill, Stephan W; Bois, Justin S

    2011-06-01

    Nearly 60 years ago, Alan Turing showed theoretically how two chemical species, termed morphogens, diffusing and reacting with each other can generate spatial patterns. Diffusion plays a crucial part in transporting chemical signals through space to establish the length scale of the pattern. When coupled to chemical reactions, mechanical processes - forces and flows generated by motor proteins - can also define length scales and provide a mechanochemical basis for morphogenesis. forces and flows generated by motor proteins - can also define length scales and provide a mechanochemical basis for morphogenesis.

  15. Optimal Piecewise Linear Basis Functions in Two Dimensions

    Energy Technology Data Exchange (ETDEWEB)

    Brooks III, E D; Szoke, A

    2009-01-26

    We use a variational approach to optimize the center point coefficients associated with the piecewise linear basis functions introduced by Stone and Adams [1], for polygonal zones in two Cartesian dimensions. Our strategy provides optimal center point coefficients, as a function of the location of the center point, by minimizing the error induced when the basis function interpolation is used for the solution of the time independent diffusion equation within the polygonal zone. By using optimal center point coefficients, one expects to minimize the errors that occur when these basis functions are used to discretize diffusion equations, or transport equations in optically thick zones (where they approach the solution of the diffusion equation). Our optimal center point coefficients satisfy the requirements placed upon the basis functions for any location of the center point. We also find that the location of the center point can be optimized, but this requires numerical calculations. Curiously, the optimum center point location is independent of the values of the dependent variable on the corners only for quadrilaterals.

  10. Fusion basis for lattice gauge theory and loop quantum gravity

    CERN Document Server

    Delcamp, Clement; Riello, Aldo

    2016-01-01

    We introduce a new basis for the gauge--invariant Hilbert space of lattice gauge theory and loop quantum gravity in $(2+1)$ dimensions, the fusion basis. In doing so, we shift the focus from the original lattice (or spin--network) structure directly to that of the magnetic (curvature) and electric (torsion) excitations themselves. These excitations are classified by the irreducible representations of the Drinfel'd double of the gauge group, and can be readily "fused" together by studying the tensor product of such representations. We will also describe in detail the ribbon operators that create and measure these excitations and make the quasi--local structure of the observable algebra explicit. Since the fusion basis allows for both magnetic and electric excitations from the onset, it turns out to be a precious tool for studying the large scale structure and coarse--graining flow of lattice gauge theories and loop quantum gravity. This is in neat contrast with the widely used spin--network basis, in which it ...

    International Nuclear Information System (INIS)

    This report contains the design basis for a generic molten-salt solar power tower. A solar power tower uses a field of tracking mirrors (heliostats) that redirect sunlight on to a centrally located receiver mounted on top a tower, which absorbs the concentrated sunlight. Molten nitrate salt, pumped from a tank at ground level, absorbs the sunlight, heating it up to 565 C. The heated salt flows back to ground level into another tank where it is stored, then pumped through a steam generator to produce steam and make electricity. This report establishes a set of criteria upon which the next generation of solar power towers will be designed. The report contains detailed criteria for each of the major systems: Collector System, Receiver System, Thermal Storage System, Steam Generator System, Master Control System, and Electric Heat Tracing System. The Electric Power Generation System and Balance of Plant discussions are limited to interface requirements. This design basis builds on the extensive experience gained from the Solar Two project and includes potential design innovations that will improve reliability and lower technical risk. This design basis document is a living document and contains several areas that require trade-studies and design analysis to fully complete the design basis.

    We discuss a strategy of sparse approximation that is based on the use of an overcomplete basis, and evaluate its performance when a random matrix is used as this basis. A small combination of basis vectors is chosen from a given overcomplete basis, according to a given compression rate, such that they compactly represent the target data with as small a distortion as possible. As a selection method, we study the {{\\ell}0} - and {{\\ell}1} -based methods, which employ the exhaustive search and {{\\ell}1} -norm regularization techniques, respectively. The performance is assessed in terms of the trade-off relation between the distortion and the compression rate. First, we evaluate the performance analytically in the case that the methods are carried out ideally, using methods of statistical mechanics. The analytical result is then confirmed by performing numerical experiments on finite size systems, and extrapolating the results to the infinite-size limit. Our result clarifies the fact that the {{\\ell}0} -based method greatly outperforms the {{\\ell}1} -based one. An interesting outcome of our analysis is that any small value of distortion is achievable for any fixed compression rate r in the large-size limit of the overcomplete basis, for both the {{\\ell}0} - and {{\\ell}1} -based methods. The difference between these two methods is manifested in the size of the overcomplete basis that is required in order to achieve the desired value for the distortion. As the desired distortion decreases, the required size grows in a polynomial and an exponential manners for the {{\\ell}0} - and {{\\ell}1} -based methods, respectively. Second, we examine the practical performances of two well-known algorithms, orthogonal matching pursuit and approximate message passing, when they are used to execute the {{\\ell}0} - and {{\\ell}1} -based methods, respectively. Our examination shows that orthogonal matching pursuit achieves a much better performance than the exact execution of

    BaSi2 has been known as a wide gap semiconductor with an intrinsic low lattice thermal conductivity, therefore may be a promising environmental friendly thermoelectric (TE) material with abundant constituent elements. In this work, NixBa1-xSi2 compounds with 0≤x≤0.3 are synthesized by arc melting. The resistivity, thermal conductivity and Seebeck coefficient are measured in the temperature range of 300-850K. The resistivity of the undoped BaSi2 is as high as 480mOhmṡcm at room temperature. Through Ni-doping, both resistivity and the Seebeck coefficient decrease dramatically. Meanwhile, the total thermal conductivity has no apparent difference due to Ni-doping. The lattice thermal conductivity decreases with increasing temperature monotonously to be lower than 1W/mṡK at high temperatures.

    Amir; Matzner; Shtrikman

    2000-02-01

    The problem of acoustic radiation from a cylindrical pipe with an infinite flange has been discussed in a number of papers. The most common approach is to decompose the field inside the pipe over a basis of Bessel functions. A very large number of basis functions is usually required, with a large degree of ripple appearing as an artifact in the solution. In this paper it is shown that a close analysis of the velocity field near the corner yields a new family of functions, which are called "edge functions." Using this set of functions as test functions and applying the moment method on the boundary between the waveguide and free space, a solution is obtained with greatly improved convergence properties and no ripple.

  18. Epidemiologic measures of risk as a basis for legal compensation

    International Nuclear Information System (INIS)

    The scientific basis for compensation of persons developing cancer who have a documented history of exposure to radiation or other carcinogens is an important legal issue. The measure Relative Attributable Risk (RAR) has been proposed as a basis for determining eligibility for compensation. The purpose of this report is to present results of an analysis of the magnitude and sources of uncertainty in the RAR measure. The range of 1/106/rad-year to 6/106/rad-year was chosen as a reasonable range of excess-risk estimates for thyroid cancer based on published estimates. The use of such a range in risk estimates produces very wide variability in RAR estimates. Uncertainty in underlying incidence levels and in dosimetry are other major factors contributing to large variability in estimated RAR levels

    "Resilience” describes how systems operate at an acceptable level of normalcy despite disturbances or threats. In this paper we first consider the cognitive, cyber-physical interdependencies inherent in critical infrastructure systems and how resilience differs from reliability to mitigate these risks. Terminology and metrics basis are provided to integrate the cognitive, cyber-physical aspects that should be considered when defining solutions for resilience. A practical approach is taken to roll this metrics basis up to system integrity and business case metrics that establish “proper operation” and “impact.” A notional chemical processing plant is the use case for demonstrating how the system integrity metrics can be applied to establish performance, and

  20. Relevant Assumptions at the basis of the UMAE uncertainty methodology

    International Nuclear Information System (INIS)

    This paper deals with preliminary results of the application of UMAE (Uncertainty Methodology based upon Accuracy Extrapolation) uncertainty procedure to the Uncertainty Methods Study (UMS) proposed by OECD/CSNI. The UMAE allows the evaluation of the error made by a system thermalhydraulic code when predicting a nuclear power plant transient scenario. The UMS is an international activity proposed with the aim of comparing the basic assumptions and the results produced by five uncertainty methodologies. The transient adopted as the object of the analysis is a small break LOCA performed in the Japanese Large Scale Test Facility (LSTF) previously adopted for International Standard Problem 26. The analysis of ten experiments performed in differently scaled facilities have been used as a basis for extrapolation of the accuracy. The hypothesis at the basis of the methodology and the main steps are discussed. (author)

  1. Two Normal Basis Multiplication Algorithms for GF(2n)

    FAN Haining; LIU Duo; DAI Yiqi

    2006-01-01

    For software implementations, word-level normal basis multiplication algorithms utilize the full data-path of the processor, and hence are more efficient than the bit-level multiplication algorithm presented in the IEEE standard P1363-2000. In this paper, two word-level normal basis multiplication algorithms are proposed for GF(2n). The first algorithm is suitable for high complexity normal bases, while the second algorithm is fast for type-Ⅰ optimal normal bases and low complexity normal bases. Theoretical analyses and experimental results both indicate that the presented algorithms are efficient in GF(2233), GF(2283), GF(2409),and GF(2571), which are four of the five binary fields recommended by the National Institute of Standards and Technology (NIST) for the elliptic curve digital signature algorithm (ECDSA) applications.

    Przekop, Adam; Guo, Xinyun; Rizzi, Stephen A.

    2010-01-01

    Three procedures to guide selection of an efficient modal basis in a nonlinear random response analysis are examined. One method is based only on proper orthogonal decomposition, while the other two additionally involve smooth orthogonal decomposition. Acoustic random response problems are employed to assess the performance of the three modal basis selection approaches. A thermally post-buckled beam exhibiting snap-through behavior, a shallowly curved arch in the auto-parametric response regime and a plate structure are used as numerical test articles. The results of the three reduced-order analyses are compared with the results of the computationally taxing simulation in the physical degrees of freedom. For the cases considered, all three methods are shown to produce modal bases resulting in accurate and computationally efficient reduced-order nonlinear simulations.

    2013-01-01

    A surface integral formulation is developed for the T matrix of a homogenous and isotropic particle of arbitrary shape, which employs scalar basis functions represented by the translation matrix elements of the vector spherical wave functions. The formulation begins with the volume integral equation for scattering by the particle, which is transformed so that the vector and dyadic components in the equation are replaced with associated dipole and multipole level scalar harmonic wave functions. The approach leads to a volume integral formulation for the T matrix, which can be extended, by use of Green's identities, to the surface integral formulation. The result is shown to be equivalent to the traditional surface integral formulas based on the VSWF basis.

    Color constancy is almost exclusively modeled with diagonal transforms. However, the choice of basis under which diagonal transforms are taken is traditionally ad hoc. Attempts to remedy the situation have been hindered by the fact that no joint characterization of the conditions for {sensors, illuminants, reflectances} to support diagonal color constancy has previously been achieved. In this work, we observe that the von Kries compatibility conditions are impositions only on the sensor measu...

    Fast, Anne A; Olson, Kristina R; Mandel, Gregory N

    2016-08-01

    Lay people routinely misunderstand or do not obey laws protecting intellectual property (IP), leading to a variety of (largely unsuccessful) efforts by policymakers, IP owners, and researchers to change those beliefs and behaviors. The current work tests a new approach, inquiring whether lay people's views about IP protection can be modified by arguments concerning the basis for IP rights. Across 2 experiments, 572 adults (recruited through Amazon Mechanical Turk) read 1 of 6 arguments about the basis for IP protection (incentives, natural rights, expressive rights, plagiarism, commons, or no argument). Participants then reported their general support for IP protection. Participants also reported their evaluations of 2 scenarios that involved infringement of IP rights, including cases in which there were mitigating experiences (e.g., the copier acknowledged the original source), and completed several demographic questions. Three primary findings emerged: (a) exposure to the importance of the public commons (and to a lesser extent, exposure to the argument that plagiarism is the basis of IP protection) led participants to become less supportive of IP protection than the incentives, natural rights, expressive rights, and control conditions; (b) people believed that infringement was more acceptable if the infringer acknowledged the original creator of the work; and (c) older adults and women were especially likely to see infringement as problematic. These findings illustrate several ways in which lay beliefs are at odds with legal doctrine, and suggest that people's views about IP protection can be shaped in certain ways by learning the basis for IP rights.

  4. Basis convergence of range-separated density-functional theory

    International Nuclear Information System (INIS)

    Range-separated density-functional theory (DFT) is an alternative approach to Kohn-Sham density-functional theory. The strategy of range-separated density-functional theory consists in separating the Coulomb electron-electron interaction into long-range and short-range components and treating the long-range part by an explicit many-body wave-function method and the short-range part by a density-functional approximation. Among the advantages of using many-body methods for the long-range part of the electron-electron interaction is that they are much less sensitive to the one-electron atomic basis compared to the case of the standard Coulomb interaction. Here, we provide a detailed study of the basis convergence of range-separated density-functional theory. We study the convergence of the partial-wave expansion of the long-range wave function near the electron-electron coalescence. We show that the rate of convergence is exponential with respect to the maximal angular momentum L for the long-range wave function, whereas it is polynomial for the case of the Coulomb interaction. We also study the convergence of the long-range second-order Møller-Plesset correlation energy of four systems (He, Ne, N2, and H2O) with cardinal number X of the Dunning basis sets cc − p(C)V XZ and find that the error in the correlation energy is best fitted by an exponential in X. This leads us to propose a three-point complete-basis-set extrapolation scheme for range-separated density-functional theory based on an exponential formula

  7. Social parasitism and the molecular basis of phenotypic evolution

    Directory of Open Access Journals (Sweden)

    Alessandro eCini

    2015-02-01

    Full Text Available Contrasting phenotypes arise from similar genomes through a combination of losses, gains, co-option and modifications of inherited genomic material. Understanding the molecular basis of this phenotypic diversity is a fundamental challenge in modern evolutionary biology. Comparisons of the genes and their expression patterns underlying traits in pairs of closely related species offer an unrivalled opportunity to evaluate the extent to which genomic material is reorganised to produce novel traits. Advances in molecular methods now allow us to dissect the molecular machinery underlying phenotypic diversity in almost any organism, from single-celled organisms to the most complex vertebrates. Here we discuss how comparisons of social parasites and their free-living hosts may provide unique insights into the molecular basis of phenotypic evolution. Social parasites evolve from a social ancestor and are specialised to exploit the socially acquired resources of their closely-related, free-living social host. Molecular comparisons of such species pairs can reveal how genomic material is re-organised in the loss of ancestral traits (i.e. of free-living traits in the parasites and the gain of new ones (i.e. specialist traits required for a parasitic lifestyle. We define hypotheses on the molecular basis of phenotypes in the evolution of social parasitism and discuss their wider application in understanding the molecular basis of phenotypic diversity within the theoretical framework of phenotypic plasticity and shifting reaction norms. Currently there are no data available to test these hypotheses, and so we also provide some proof of concept data for our conceptual model using the paper wasp social parasite-host system (Polistes sulcifer - Polistes dominula. This conceptual framework and first empirical data provide a spring-board for directing future genomic analyses on exploiting social parasites as a route to understanding the evolution of phenotypic

    The electronic structure basis of the extremely large magnetoresistance in layered non-magnetic tungsten ditelluride has been investigated by angle-resolved photoelectron spectroscopy. Hole and electron pockets of approximately the same size were found at the Fermi level, suggesting that carrier compensation should be considered the primary source of the effect. The material exhibits a highly anisotropic, quasi one-dimensional Fermi surface from which the pronounced anisotropy of the magnetor...

  11. DBT - Basis for developing a European physical protection concept

    International Nuclear Information System (INIS)

    It is one of the security fundamentals that a State's physical protection system should be based on the State's current evaluation of the threat. An internationally accepted methodology for the design and evaluation of physical protection of nuclear material and facilities is the Design Basis Threat methodology. This methodology uses a definition of a threat, which is developed from the State's evaluation of the threat. Open borders inside the European Union enable those individuals, who could create a potential threat to nuclear material or nuclear facilities, to move from one Member State to another without restrictions or the realistic opportunity for relevant authorities to be informed timely about such possible movements. Taking into account this in the States' threat evaluation the results have got a potential to become more and more similar inside the Europe Union. The similarity in the results may put in question the idea of defining national Design Basis Threat, DBT, in each State. The similarities in the threat evaluation and the DBT will then contribute to more similarity in the design basis for physical protection concepts. The DBT is an important basis, but there are more factors, which determine the design and the evaluation of a physical protection concept. These factors are related to the State's physical protection system, which consists of elements like the State's response capabilities to malevolent acts against nuclear material or facilities, the culture and the legal and regulatory framework of physical protection. The development of a European physical protection concept would clearly be part of the efforts and policy in order to harmonize rules, regulations and standards within the European Union. This document will not touch the political aspects and potential problems related of harmonization in the European Union and will not speculate upon the possibilities. The DBT methodology will be explained. The relevant elements which would be

    Noncommutative invariant theory is a generalization of the classical invariant theory of the action of $SL(2,\\IC)$ on binary forms. The dimensions of the spaces of invariant noncommutative polynomials coincide with the numbers of certain noncrossing partitions. We give an elementary combinatorial explanation of this fact by constructing a noncrossing basis of the homogeneous components. Using the theory free stochastic measures this provides a combinatorial proof of the Molien-Weyl formula in...

    We consider Clifford algebras over the field of real or complex numbers as a quotient algebra without fixed basis. We present classification of Clifford algebra elements based on the notion of quaternion type. This classification allows us to reveal and prove a number of new properties of Clifford algebras. We rely on the operations of conjugation to introduce the notion of quaternion type. Also we find relations between the concepts of quaternion type and rank of Clifford algebra element.

    Full Text Available The growing interest at the usage of strategical management as the means of organization of enterprise control for the provision of positive perspectives of growing is limited by the owners’ wish to get a profit nowadays. At the same time long-lasting perspective of stable functioning interests the authority in a little way and the main attention is paid upon the current problems’ solutions. The aim of the article is the activisation of usage of basic strategies as the means of the basis of enterprise development for the coordination of authorities’ actions with the aim of enterprise functioning. The theory «7-S», which fully reveals the basic strategy as the basis of enterprise development, is looked upon. Touching upon the existing models of development of organization systems, basic strategies for the enterprises of light industry are generalized. It is settled that the solution about basic strategical landmark is accepted on the basis of notions about the results of comparison of alternative variants. The logical interaction component of enterprise development with the definition of the place of basic strategies is built. As only owner or his representative can accept the decision about the enterprise development, a quantity of probable strategical actions on account of market situation is formed

  11. Design basis tropical cyclone for nuclear power plants

    International Nuclear Information System (INIS)

    The general characteristics of tropical cyclones are discussed in this Safety Guide, with particular emphasis on their pressure and wind structures in the light of available data. General methods are given for the evaluation of the relevant parameters of a Probable Maximum Tropical Cyclone (PMTC), which can be used as the Design Basis Tropical Cyclone (DBTC); these parameters then serve as inputs for the derivation of a design basis surge and a design basis wind. A possible method is also given for the evaluation of the PMTC pressure and wind field based on an approach valid primarily for a particular region. This method depends on the results of a theoretical study on the tropical cyclone structure and makes use of a large amount of data, including aircraft reconnaissance observations for 170 most intense tropical cyclones near the coast of Japan, Taiwan and the Philippines for the period 1960-1974, as well as detailed analyses of all the extreme storms along the Gulf of Mexico and the east coast of the USA during 1900-1978, for the determination of the necessary parameters

  12. ALWR utility requirements - A technical basis for updated emergency planning

    International Nuclear Information System (INIS)

    U.S. utilities, with substantial support from international utilities, are developing a comprehensive set of design requirements in the form of a Utility Requirements Document (URD) as part of an industry wide effort to establish a technical foundation for the next generation of light water reactors. A key aspect of the URD is a set of severe accident-related design requirements which have been developed to provide a technical basis for updated emergency planning for the ALWR. The technical basis includes design criteria for containment performance and offsite dose during severe accident conditions. An ALWR emergency planning concept is being developed which reflects this severe accident capability. The main conclusion from this work is that the likelihood and consequences of a severe accident for an ALWR are fundamentally different from that assumed in the technical basis for existing emergency planning requirements, at least in the U.S. The current technical understanding of severe accident risk is greatly improved compared to that available when the existing U.S. emergency planning requirements were established nearly 15 years ago, and the emerging ALWR designs have superior core damage prevention and severe accident mitigation capability. Thus, it is reasonable and prudent to reflect this design capability in the emergency planning requirements for the ALWR. (author)

  13. Evolution of Safety Basis Documentation for the Fernald Site

    International Nuclear Information System (INIS)

    The objective of the Department of Energy's (DOE) Fernald Closure Project (FCP), in suburban Cincinnati, Ohio, is to safely complete the environmental restoration of the Fernald site by 2006. Over 200 out of 220 total structures, at this DOE plant site which processed uranium ore concentrates into high-purity uranium metal products, have been safely demolished, including eight of the nine major production plants. Documented Safety Analyses (DSAs) for these facilities have gone through a process of simplification, from individual operating Safety Analysis Reports (SARs) to a single site-wide Authorization Basis containing nuclear facility Bases for Interim Operations (BIOs) to individual project Auditable Safety Records (ASRs). The final stage in DSA simplification consists of project-specific Integrated Health and Safety Plans (I-HASPs) and Nuclear Health and Safety Plans (N-HASPs) that address all aspects of safety, from the worker in the field to the safety basis requirements preserving the facility/activity hazard categorization. This paper addresses the evolution of Safety Basis Documentation (SBD), as DSAs, from production through site closure

The main document describes the risk binning process and the technical basis for assigning risk bins to the representative accidents involving the release of dried radioactive waste materials from the Demonstration Bulk Vitrification System (DBVS) and to the associated represented hazardous conditions. Appendices D through F provide the technical basis for assigning risk bins to the representative dried waste release accident and associated represented hazardous conditions for the Contact-Handled Transuranic Mixed (CH-TRUM) Waste Packaging Unit (WPU). The risk binning process uses an evaluation of the frequency and consequence of a given representative accident or represented hazardous condition to determine the need for safety structures, systems, and components (SSC) and technical safety requirement (TSR)-level controls. A representative accident or a represented hazardous condition is assigned to a risk bin based on the potential radiological and toxicological consequences to the public and the collocated worker. Note that the risk binning process is not applied to facility workers because credible hazardous conditions with the potential for significant facility worker consequences are considered for safety-significant SSCs and/or TSR-level controls regardless of their estimated frequency. The controls for protection of the facility workers are described in RPP-23429 and RPP-23479. Determination of the need for safety-class SSCs was performed in accordance with DOE-STD-3009-94, Preparation Guide for US.

    The glycine riboswitch regulates gene expression through the cooperative recognition of its amino acid ligand by a tandem pair of aptamers. A 3.6 {angstrom} crystal structure of the tandem riboswitch from the glycine permease operon of Fusobacterium nucleatum reveals the glycine binding sites and an extensive network of interactions, largely mediated by asymmetric A-minor contacts, that serve to communicate ligand binding status between the aptamers. These interactions provide a structural basis for how the glycine riboswitch cooperatively regulates gene expression.

We find that k-meansclustering is very suitable. In order to increase the precision we introduce a nonlinear feedback term to escape from thelocal minima of energy, then we use the model to forecast the nonlinear time series which are produced by Mackey-Glassequation and stocks. By selecting the k-means clustering and the suitable feedback term, much better forecasting resultsare obtained.

  9. Design basis event consequence analyses for the Yucca Mountain project

    International Nuclear Information System (INIS)

    Design basis event (DBE) definition and analysis is an ongoing and integrated activity among the design and analysis groups of the Yucca Mountain Project (YMP). DBE's are those that potentially lead to breach of the waste package and waste form (e.g., spent fuel rods) with consequent release of radionuclides to the environment. A Preliminary Hazards Analysis (PHA) provided a systematic screening of external and internal events that were candidate DBE's that will be subjected to analyses for radiological consequences. As preparation, pilot consequence analyses for the repository subsurface and surface facilities have been performed to define the methodology, data requirements, and applicable regulatory limits

    The Bender-Dunne basis operators, T{sub −m,n}=2{sup −n}∑{sub k=0}{sup n}(n/k )q{sup k}p{sup −m}q{sup n−k} where q and p are the position and momentum operators, respectively, are formal integral operators in position representation in the entire real line R for positive integers n and m. We show, by explicit construction of a dense domain, that the operators T{sub −m,n}'s are densely defined operators in the Hilbert space L{sup 2}(R)

    Ho, E

    1991-04-01

    In designing the curriculum for pre and post registration midwifery courses, the author has utilised an andragogical model. This term refers to the art and science of teaching adults (Knowles 1978). The ideas that Knowles (1978) put forward about andragogy while not new, have been implemented in adult education and are certainly relevant to the modern practice of midwifery education. The aim of this paper is to examine the two extreme philosophical views about the nature of man and to provide an epistemological basis for andragogy in midwifery education. PMID:2020289

    2012-01-01

    In this paper,a multiscale problem arising in material science is considered.The problem involves a random coefficient which is assumed to be a perturbation of a deterministic coefficient,in a sense made precisely in the body of the text.The homogenized limit is then computed by using a perturbation approach.This computation requires repeatedly solving a corrector-like equation for various configurations of the material.For this purpose,the reduced basis approach is employed and adapted to the specific context.The authors perform numerical tests that demonstrate the efficiency of the approach.

    Full Text Available Steganographic tools and techniques are becoming more potential and widespread. Illegal use of steganography poses serious challenges to the law enforcement agencies. Limited work has been carried out on supervised steganalysis using neural network as a classifier. We present a combined method of identifying the presence of covert information in a carrier image using fisher’s linear discriminant (FLD function followed by the radial basis function (RBF. Experiments show promising results when compared to the existing supervised steganalysis methods, but arranging the retrieved information is still a challenging problem.

    2014-01-01

    The rapid falloff of the oscillator functions at large radius (Gaussian asymptotics) makes them poorly suited for the description of the asymptotic properties of the nuclear wave function, a problem which becomes particularly acute for halo nuclei. We consider an alternative basis for ab initio no-core configuration interaction (NCCI) calculations, built from Coulomb-Sturmian radial functions, allowing for realistic (exponential) radial falloff. NCCI calculations are carried out for the neutron-rich He isotopes, and estimates are made for the RMS radii of the proton and neutron distributions.

    2002-12-01

    This paper provides a scientific foundation for the biofield: the complex, extremely weak electromagnetic field of the organism hypothesized to involve electromagnetic bioinformation for regulating homeodynamics. The biofield is a useful construct consistent with bioelectromagnetics and the physics of nonlinear, dynamical, nonequilibrium living systems. It offers a unifying hypothesis to explain the interaction of objects or fields with the organism, and is especially useful toward understanding the scientific basis of energy medicine, including acupuncture, biofield therapies, bioelectromagnetic therapies, and homeopathy. The rapid signal propagation of electromagnetic fields comprising the biofield as well as its holistic properties may account for the rapid, holistic effects of certain alternative and complementary medical interventions.

    2014-11-01

    The electronic structure basis of the extremely large magnetoresistance in layered nonmagnetic tungsten ditelluride has been investigated by angle-resolved photoelectron spectroscopy. Hole and electron pockets of approximately the same size were found at low temperatures, suggesting that carrier compensation should be considered the primary source of the effect. The material exhibits a highly anisotropic Fermi surface from which the pronounced anisotropy of the magnetoresistance follows. A change in the Fermi surface with temperature was found and a high-density-of-states band that may take over conduction at higher temperatures and cause the observed turn-on behavior of the magnetoresistance in WTe2 was identified.

    Binder, S; Hagen, G; Papenbrock, T; Wendt, K A

    2015-01-01

    We develop interactions from chiral effective field theory (EFT) that are tailored to the harmonic oscillator basis. As a consequence, ultraviolet convergence with respect to the model space is implemented by construction and infrared convergence can be achieved by enlarging the model space for the kinetic energy. We derive useful analytical expressions for an exact and efficient calculation of matrix elements. By fitting to realistic phase shifts and deuteron data we construct an effective interaction from chiral EFT at next-to-leading order. Many-body coupled-cluster calculations of nuclei up to 132Sn exhibit a fast convergence of ground-state energies and radii in feasible model spaces.

  5. Nonlinear Image Restoration Using a Radial Basis Function Network

    Directory of Open Access Journals (Sweden)

    Iiguni Youji

    2004-01-01

    Full Text Available We propose a nonlinear image restoration method that uses the generalized radial basis function network (GRBFN and a regularization method. The GRBFN is used to estimate the nonlinear blurring function. The regularization method is used to recover the original image from the nonlinearly degraded image. We alternately use the two estimation methods to restore the original image from the degraded image. Since the GRBFN approximates the nonlinear blurring function itself, the existence of the inverse of the blurring process does not need to be assured. A method of adjusting the regularization parameter according to image characteristics is also presented for improving restoration performance.

    2009-01-01

    The recent resurgence of interest in spatio-temporal neural network as speech recognition tool motivates the present investigation. In this paper an approach was developed based on temporal radial basis function "TRBF" looking to many advantages: few parameters, speed convergence and time invariance. This application aims to identify vowels taken from natural speech samples from the Timit corpus of American speech. We report a recognition accuracy of 98.06 percent in training and 90.13 in test on a subset of 6 vowel phonemes, with the possibility to expend the vowel sets in future.

  10. Molecular basis for the CAT-2 null phenotype in maize

    International Nuclear Information System (INIS)

    Previous reports have described several maize lines whose developmental patterns of catalase gene expression vary from the typical maize line, W64A. Among these variants are the lines A16 and A338, both found to be null for the CAT-2 protein. Identification of a third CAT-2 null line, designated A340, is described. RNA blots and S1 nuclease protection analysis, using [32P]-labeled dCTP, indicate that all three CAT-2 null lines produce a similarly shortened Cat2 transcript. The molecular basis for this aberrant Cat2 transcript is discussed

  12. Dynamics of learning near singularities in radial basis function networks.

    Science.gov (United States)

    Wei, Haikun; Amari, Shun-Ichi

    2008-09-01

    The radial basis function (RBF) networks are one of the most widely used models for function approximation in the regression problem. In the learning paradigm, the best approximation is recursively or iteratively searched for based on observed data (teacher signals). One encounters difficulties in such a process when two component basis functions become identical, or when the magnitude of one component becomes null. In this case, the number of the components reduces by one, and then the reduced component recovers as the learning process proceeds further, provided such a component is necessary for the best approximation. Strange behaviors, especially the plateau phenomena, have been observed in dynamics of learning when such reduction occurs. There exist singularities in the space of parameters, and the above reduction takes place at the singular regions. This paper focuses on a detailed analysis of the dynamical behaviors of learning near the overlap and elimination singularities in RBF networks, based on the averaged learning equation that is applicable to both on-line and batch mode learning. We analyze the stability on the overlap singularity by solving the eigenvalues of the Hessian explicitly. Based on the stability analysis, we plot the analytical dynamic vector fields near the singularity, which are then compared to those real trajectories obtained by a numeric method. We also confirm the existence of the plateaus in both batch and on-line learning by simulation. PMID:18693082

    Rigorous optical simulations of 3-dimensional nano-photonic structures are an important tool in the analysis and optimization of scattering properties of nano-photonic devices or parameter reconstruction. To construct geometrically accurate models of complex structured nano-photonic devices the finite element method (FEM) is ideally suited due to its flexibility in the geometrical modeling and superior convergence properties. Reduced order models such as the reduced basis method (RBM) allow to construct self-adaptive, error-controlled, very low dimensional approximations for input-output relationships which can be evaluated orders of magnitude faster than the full model. This is advantageous in applications requiring the solution of Maxwell's equations for multiple parameters or a single parameter but in real time. We present a reduced basis method for 3D Maxwell's equations based on the finite element method which allows variations of geometric as well as material and frequency parameters. We demonstrate accuracy and efficiency of the method for a light scattering problem exhibiting a resonance in the electric field.

  15. Anatomicopathological basis and clinical diagnostic significance of Kerley's A line

    International Nuclear Information System (INIS)

    Objective: To study anatomic and pathological basis of Kerley's A line, and to evaluate the role of Kerley's A line in differential diagnosis of diffuse lung diseases (DLD). Methods: HRCT scans, gross specimen section(50-100 μm thickness) and histologic section(5-8 μm thickness) were performed and analyzed comparatively on 28 dry lung specimens from the patients with coal worker's pneumoconiosis and occupational exposure history to coal dusts. At the same time, HRCT images of 176 patients with DLD were retrospectively reviewed for the detection of Kerley's A line. Results: Kerley's A lines were seen in 17 of 28 lung specimens on coronal HRCT images. The anatomic basis of Kerley's A line represented the continuity of two or more thickened interlobular septa (14 eases) and incomplete fibrotic septa between segments or subsegments (3 cases). Histologically, the linear opacities represented the deposits of coal dust, fibrosis, edema, inflammation, thickened vessel wall within interlobular septa. Kerley's A lines were present in 11 of 176 patients (6.3%) including interstitial pulmonary edema (5 cases), viral pneumonia (2 cases), lymphangitic carcinomatosis (2 cases), sarcoidosis (1 cases) and pulmonary alveolar proteinosis (1 cases). Conclusion: Kerley's A line has a limited usefulness in the differential diagnosis of DLD because it is seen infrequently and not discermable. (authors)

    J. Lombard

    2004-07-01

    Full Text Available Mythicity as basis for comparative literature, with reference to water snake symbolism Mythicity can be defined as the deliberate intention of probing the numinous dimensions of human existence by means of literature, i.e. mainly narrative forms. In this article the water snake is chosen as prominent archetypal symbol in order to investigate the functioning of mythicity. The water snake is an important symbol in the Southern African context, with its origins in Khoesan ritual and mythology. Recently several stories about water snakes and related mythological creatures have been published in Afrikaans novels and short stories. The water snake has also assimilated influences, inter alia from European, Asian and other African cultures. In this article the potential of mythicity is specifically investigated insofar as it can be utilised as basis for comparative literature. For this purpose the numinous dimensions of a mythic story are treated as equally important as the narrative dimensions. This dialectical balance is therefore used as the main criterion for the comparison of mythic texts. Other related aspects are discussed, namely the importance of the historical context, Jung’s theory of archetypes and the unconscious, and the role of interpretational devices such as metaphor, metonymy, symbolism and allegory. If the balance between numinosity and narrativity is not maintained, the mythic potential of a text is usually reduced. When writers succeed in utilising mythicity as an “open”, dynamic interpretational process, mythic relevance can still be guaranteed within a present-day, postmodern context.

    2016-04-01

    The MHD theory of the field-line resonance is of great importance for the understanding of ultra low-frequency waves in the magnetosphere. Most theoretical works concerning field-line resonance use the electric field as the basis set. In an ideal MHD plasma the field-aligned component of the electrical field vanishes because of the frozen-in theorem. However, a field-aligned current flows to maintain quasi-neutrality. This field-aligned current can only be carried by the transverse MHD Alfvèn wave and is therefore a characteristic feature of these types of waves. In this study we investigate the field-line resonance phenomenon using a three dimensional current vector space as the basis set. Using the model of the box magnetosphere of Southwood (1974) we derive an equation for the field-aligned current. This equation provides a simpler and more detailed insight into the coupling process between the fast mode and the Alfvèn mode. Furthermore we investigate the effect of the Hall current on the field-aligned current by including the Hall term in Ohm's law. It is shown that in some situations the Hall current can nullify the filed-aligned current and therefore prevent the resonance.

  19. AN APPROACH TO SAFETY DESIGN BASIS DOCUMENTATION CHANGE CONTROL

    International Nuclear Information System (INIS)

    This paper describes a safety design basis documentation change control process. The process identifies elements that can be used to manage the project/facility configuration during design evolution through the Initiation, Definition, and Execution project phases. The project phases addressed by the process are defined in US Department of Energy (DOE) Order (O) 413.3A, Program and Project Management for the Acquisition of Capital Assets, in support of DOE project Critical Decisions (CD). This approach has been developed for application to two Hanford Site projects in their early CD phases and is considered to be a key element of safety and design integration. As described in the work that has been performed, the purpose of change control is to maintain consistency among design requirements, the physical configuration, related facility documentation, and the nuclear safety basis during the evolution of the design. The process developed (1) ensures an appropriate level of rigor is applied at each project phase and (2) is considered to implement the requirements and guidance provided in DOE-STD-1189-2008, Integration of Safety into the Design Process. Presentation of this work is expected to benefit others in the DOE Complex that may be implementing DOE-STD-1189-2008 or managing nuclear safety documentation in support of projects in-process

    The Hanford External Dosimetry Technical Basis Manual PNL-MA-842 documents the design and implementation of the external dosimetry system used at Hanford. The manual describes the dosimeter design, processing protocols, dose calculation methodology, radiation fields encountered, dosimeter response characteristics, limitations of dosimeter design under field conditions, and makes recommendations for effective use of the dosimeters in the field. The manual describes the technical basis for the dosimetry system in a manner intended to help ensure defensibility of the dose of record at Hanford and to demonstrate compliance with 10 CFR 835, DOELAP, DOE-RL, ORP, PNSO, and Hanford contractor requirements. The dosimetry system is operated by PNNL’s Hanford External Dosimetry Program which provides dosimetry services to all Hanford contractors. The primary users of this manual are DOE and DOE contractors at Hanford using the dosimetry services of PNNL. Development and maintenance of this manual is funded directly by DOE and DOE contractors. Its contents have been reviewed and approved by DOE and DOE contractors at Hanford through the Hanford Personnel Dosimetry Advisory Committee which is chartered and chaired by DOE-RL and serves as means of coordinating dosimetry practices across contractors at Hanford. This manual was established in 1996. Since inception, it has been revised many times and maintained by PNNL as a controlled document with controlled distribution. Rev. 0 marks the first revision to be released through PNNL’s Electronic Records & Information Capture Architecture (ERICA) database.

  1. Algebraic evaluation of matrix elements in the Laguerre function basis

    Science.gov (United States)

    McCoy, A. E.; Caprio, M. A.

    2016-02-01

    The Laguerre functions constitute one of the fundamental basis sets for calculations in atomic and molecular electron-structure theory, with applications in hadronic and nuclear theory as well. While similar in form to the Coulomb bound-state eigenfunctions (from the Schrödinger eigenproblem) or the Coulomb-Sturmian functions (from a related Sturm-Liouville problem), the Laguerre functions, unlike these former functions, constitute a complete, discrete, orthonormal set for square-integrable functions in three dimensions. We construct the SU(1, 1) × SO(3) dynamical algebra for the Laguerre functions and apply the ideas of factorization (or supersymmetric quantum mechanics) to derive shift operators for these functions. We use the resulting algebraic framework to derive analytic expressions for matrix elements of several basic radial operators (involving powers of the radial coordinate and radial derivative) in the Laguerre function basis. We illustrate how matrix elements for more general spherical tensor operators in three dimensional space, such as the gradient, may then be constructed from these radial matrix elements.

  2. Toward a Scientifically Rigorous Basis for Developing Mapped Ecological Regions

    Science.gov (United States)

    McMahon, Gerard; Wiken, Ed B.; Gauthier, David A.

    2004-04-01

    Despite the wide use of ecological regions in conservation and resource-management evaluations and assessments, a commonly accepted theoretical basis for ecological regionalization does not exist. This fact, along with the paucity of focus on ecological regionalization by professional associations, journals, and faculties, has inhibited the advancement of a broadly acceptable scientific basis for the development, use, and verification of ecological regions. The central contention of this article is that ecological regions should improve our understanding of geographic and ecological phenomena associated with biotic and abiotic processes occurring in individual regions and also of processes characteristic of interactions and dependencies among multiple regions. Research associated with any ecoregional framework should facilitate development of hypotheses about ecological phenomena and dominant landscape elements associated with these phenomena, how these phenomena are structured in space, and how they function in a hierarchy. Success in addressing the research recommendations outlined in this article cannot occur within an ad hoc, largely uncoordinated research environment. Successful implementation of this plan will require activities—coordination, funding, and education—that are both scientific and administrative in nature. Perhaps the most important element of an infrastructure to support the scientific work of ecoregionalization would be a national or international authority similar to the Water and Science Technology Board of the National Academy of Sciences.

  3. Ignalina accident localisation system response to maximum design basis accident

    International Nuclear Information System (INIS)

    In this paper the study of the accident localisation system (ALS) of the Ignalina nuclear power plant (NPP) with RBMK-1500 reactors (large-power channel-type water-cooled graphite-moderated reactor) with regard to a maximum design basis accident (MDBA) is presented. The MDBA for Ignalina NPP constitutes a guillotine rupture of the maximum diameter pipe. The thermal-hydraulic and structural analyses were performed using the RELAP5, CONTAIN and ALGOR codes. The coolant mass and energy discharge source terms to the accident compartment were established using the RELAP5 code. This was then used as a source term for the long-term accident thermal-hydraulic analysis of ALS compartments employing the CONTAIN code. Results obtained by the CONTAIN calculations establish a basis for the structural analysis. A finite-element method has been used for ALS structural analysis using the ALGOR code, the results of which show that the structures of the ALS would not be breached by the pressure attained in the event of an MDBA.

    Novel basis sets are generated that target the description of valence correlation in atoms H through Ar. The new contraction coefficients are obtained according to the Atomic Natural Orbital (ANO) procedure from CCSD(T) (coupled-cluster singles and doubles with perturbative triples correction) density matrices starting from the primitive functions of Dunning et al. [J. Chem. Phys. 90, 1007 (1989); ibid. 98, 1358 (1993); ibid. 100, 2975 (1993)] (correlation consistent polarized valence X-tuple zeta, cc-pVXZ). The exponents of the primitive Gaussian functions are subject to uniform scaling in order to ensure satisfaction of the virial theorem for the corresponding atoms. These new sets, named ANO-VT-XZ (Atomic Natural Orbital Virial Theorem X-tuple Zeta), have the same number of contracted functions as their cc-pVXZ counterparts in each subshell. The performance of these basis sets is assessed by the evaluation of the contraction errors in four distinct computations: correlation energies in atoms, probing the density in different regions of space via (-3 ≤ n ≤ 3) in atoms, correlation energies in diatomic molecules, and the quality of fitting potential energy curves as measured by spectroscopic constants. All energy calculations with ANO-VT-QZ have contraction errors within "chemical accuracy" of 1 kcal/mol, which is not true for cc-pVQZ, suggesting some improvement compared to the correlation consistent series of Dunning and co-workers.

  5. Beyond design basis issues in the Republic of Korea

    International Nuclear Information System (INIS)

    Shortly after the Fukushima Daiichi accident, all nuclear facilities in the Republic of Korea were inspected to ensure the countermeasures against severe accidents were adequate and in full agreement with the safety inspection principles. In particular, a close examination of Kori Unit 1, the oldest reactor in operation in the country, was undertaken to confirm its safety during the period of continued operation beyond its design life. The inspection team consisted of 56 experts in the areas of earthquake/tsunami, electric power/fire/reactor cooling, severe accident, emergency planning and LTO. This review included: — Confirming unit safety during a design basis earthquake and tsunami; — Securing reactor cooling capability in case of station blackout due to severe flooding; — Securing containment integrity, assuming loss of reactor cooling capability; — Adequacy of the emergency response, assuming large release of radioactive materials; — Close examination of the ageing of the Kori Unit 1 AMP. Based on special inspections, investigations and research in the country, it could be confirmed that NPPs in the Republic of Korea will remain safe even during a massive earthquake and tsunami. Nevertheless, dozens of short and mid-term severe accident coping features have been recommended to better mitigate beyond design basis accidents

    The method of McCurdy, Baertschy, and Rescigno, J. Phys. B, 37, R137 (2004) is generalized to obtain a straightforward, surprisingly accurate, and scalable numerical representation for calculating the electronic wave functions of molecules. It uses a basis set of product sinc functions arrayed on a Cartesian grid, and yields 1 kcal/mol precision for valence transition energies with a grid resolution of approximately 0.1 bohr. The Coulomb matrix elements are replaced with matrix elements obtained from the kinetic energy operator. A resolution-of-the-identity approximation renders the primitive one- and two-electron matrix elements diagonal; in other words, the Coulomb operator is local with respect to the grid indices. The calculation of contracted two-electron matrix elements among orbitals requires only O(N log(N)) multiplication operations, not O(N^4), where N is the number of basis functions; N = n^3 on cubic grids. The representation not only is numerically expedient, but also produces energies and proper...

  7. Failure Rate Prediction of Active Component Using PM Basis Database

    International Nuclear Information System (INIS)

    The safety security and efficient management of NPPs (Nuclear Power Plants) have been increased after the accident of TEPCO's Fukushima nuclear power stations. The needs for the safety and efficiency are becoming more important because about 90 percent of the NPPs all over the world are more than 20 operation years old. The preventive maintenance criteria need to be flexible, considering long-term development of the equipment performance and preventive maintenance. The PMBD (Preventive Maintenance Basis Database) program was widely used for optimization of the preventive maintenance criteria. PMBD program contains all kinds of failure mechanisms for each equipment that may occur in the power plant based on RCM(Reliability-Centered Maintenance) and numerically calculate the variation of reliability and failure rate based on PM interval changes. In this study, propriety evaluation of preventive maintenance task, cycle, technical basis for cost effective preventive maintenance strategy and an appropriate evaluation were suggested by the case application of PMBD for major components in the NPPs

    Full Text Available Application of fluoroquinolones covers by experience of treatment more than 800 million patients, and presently they are one of basic classes in the antimicrobial arsenal of practical medicine. Such achievements became possible after the clear understanding of intercommunication of structure and activity of molecules of this class of antibiotics. This knowledge became the basis for the synthesis of new derivatives with a wide range, powerful activity and improved pharmacokinetic profile for the best clinical outcome. Moxifloxacin is 8-methoxyfluoroquinolon of wide spectrum which interacts mainly with DNA gyrase of gram-negative and with topoisomerase of IV type of gram-positive bacteria. He has the extended activity against gram-positive cocci, however keeps activity against gram-negative bacteria. Moxifloxacin also has good activity against atypical respiratory pathogens (Legionella of pneumophila, Chlamydia of pneumoniae and Mycoplasma of pneumoniae. Another his feature is high anti-anaerobic activity. Therefore development of domestic medication with Moxifloxacin - a fluoroquinolone 4 generations - is actual. Materials and methods Research material was a substance of Moxifloxacin hydrochloride, produced by firm «Sansh Biotech Pvt. Ltd.», India, a dosage form on the basis of Moxifloxacin - solution for infusion. Qqualitative and quantitative control of samples of the drug were conducted on parameters which characterize stability: рН, content of active substance, transparency, colour, related impurities, mechanical inclusions on methods, which are described in SPhU. Results and Discussion Proposed the drug is antibiotic of wide spectrum of action of fluoroquinolone. Moxifloxacin hydrochloride is powder pale yellow with slightly hygroscopic nature. He moderately dissolve in water and methanol, poorly will dissolve in hydrochloric acid and ethanol, and practically will not dissolve in an acetone and toluene. рН 0,2 % solution is in a range

  9. Minimization of Basis Risk in Parametric Earthquake Cat Bonds

    Science.gov (United States)

    Franco, G.

    2009-12-01

    A catastrophe -cat- bond is an instrument used by insurance and reinsurance companies, by governments or by groups of nations to cede catastrophic risk to the financial markets, which are capable of supplying cover for highly destructive events, surpassing the typical capacity of traditional reinsurance contracts. Parametric cat bonds, a specific type of cat bonds, use trigger mechanisms or indices that depend on physical event parameters published by respected third parties in order to determine whether a part or the entire bond principal is to be paid for a certain event. First generation cat bonds, or cat-in-a-box bonds, display a trigger mechanism that consists of a set of geographic zones in which certain conditions need to be met by an earthquake’s magnitude and depth in order to trigger payment of the bond principal. Second generation cat bonds use an index formulation that typically consists of a sum of products of a set of weights by a polynomial function of the ground motion variables reported by a geographically distributed seismic network. These instruments are especially appealing to developing countries with incipient insurance industries wishing to cede catastrophic losses to the financial markets because the payment trigger mechanism is transparent and does not involve the parties ceding or accepting the risk, significantly reducing moral hazard. In order to be successful in the market, however, parametric cat bonds have typically been required to specify relatively simple trigger conditions. The consequence of such simplifications is the increase of basis risk. This risk represents the possibility that the trigger mechanism fails to accurately capture the actual losses of a catastrophic event, namely that it does not trigger for a highly destructive event or vice versa, that a payment of the bond principal is caused by an event that produced insignificant losses. The first case disfavors the sponsor who was seeking cover for its losses while the

    Full Text Available This theoretical and exploratory paper aims to build a critical analysis on after-sales services, mainly regarded to manufactured goods on technological basis. The purpose of the research is to achieve some better understanding about the essential elements that are to be taken into account in conceiving such a service, after different approaches. After-sales service is a member of the service package and it can influence customer satisfaction. The studied issues can integrate policies to guiding firms in designing after-sales services. They are: definition of the service itself; strategic issues; the facilities and premises; and the operation management. We aim this theoretical research to be a pre-requisite to launch further empirical researches, mainly in the field of inter-organizational relationships. Key-words: service management; after-sales service; service operations; goods associated to services; inter-organizational relationships.

    Genomic Selection (GS) is a relatively new technology, which has already revolutionized animal breeding and which is expected to have a high impact on plant breeding. In contrast to traditional marker assisted breeding, which only focuses on specific genes. GS estimates the genetic value of...... individuals/families by using genomic information over the Whole genome. The benefits of GS include reductions in expensive and time-consuming phenotyping operations, higher genetic gains, and simultaneous selection of multiple traits. To date, GS has primarely been tested in species, which are grown as...... homogeneous varieties. For crops grown in heterogeneous families, investigations have been limited to af few theoretical considerations. The aim of the present thesis was to establish the basis for GS implementation in such species. Analyses were performed on real data from a breeding program of perennial...

  12. Deriving air quality standards on the basis of risk assessments

    International Nuclear Information System (INIS)

    A concept is proposed for deriving air quality standards on the basis of risk-dose-relationships. Five different risks are shown to be a part of any decision on the value of a definite standard. Three of these arise from the generalisation of statements on samples of objects, effects, boundary and state conditions of objects to those valid for the respective populations. These risks cannot be quantified. The remaining two risks are the risk of the incidence of effects and the risk of wrong measurements. The former risk has to be fixed by the administration while the latter results from the quality of the measurement technique. The consequences of combining these risks to a total risk are discussed.

    2016-03-18

    The non-homologous end-joining (NHEJ) pathway repairs DNA double-strand breaks (DSBs) in all domains of life. Archaea and bacteria utilize a conserved set of multifunctional proteins in a pathway termed Archaeo-Prokaryotic (AP) NHEJ that facilitates DSB repair. Archaeal NHEJ polymerases (Pol) are capable of strand displacement synthesis, whilst filling DNA gaps or partially annealed DNA ends, which can give rise to unligatable intermediates. However, an associated NHEJ phosphoesterase (PE) resects these products to ensure that efficient ligation occurs. Here, we describe the crystal structures of these archaeal (Methanocella paludicola) NHEJ nuclease and polymerase enzymes, demonstrating their strict structural conservation with their bacterial NHEJ counterparts. Structural analysis, in conjunction with biochemical studies, has uncovered the molecular basis for DNA strand displacement synthesis in AP-NHEJ, revealing the mechanisms that enable Pol and PE to displace annealed bases to facilitate their respective roles in DSB repair.

    Fabbricatore, Riccardo; Studenikin, Alexander

    2016-01-01

    We consider neutrino mixing and oscillations in presence of an arbitrary constant magnetic field with nonzero transversal $B_{\\perp}$ and longitudinal $B_{\\parallel}$ components with respect to the direction of neutrino propagation. The electromagnetic interaction of neutrinos is determined by diagonal and transition neutrino magnetic moments that are introduced for the neutrino mass states. Explicit expressions for the effective neutrino diagonal and transition magnetic moments for the flavor basis in terms of these values for the mass states are obtained. The effective evolution Hamiltonian for the flavor neutrino and the corresponding oscillation probability are derived. The role of the longitudinal magnetic field component is examined. In particular, it is shown that: 1) $B_{\\parallel}$ coupled to the corresponding magnetic moments shifts the neutrino energy, and 2) in case of nonvanishing neutrino transition magnetic moments $B_{\\parallel}$ produces an additional mixing between neutrino states, both in t...

  15. Fermion Flavors in Quaternion Basis and Infrared QCD

    International Nuclear Information System (INIS)

    I analyze the lattice simulation data of the Domain Wall Fermion in quaternion basis. As pointed out by Atiyah and Ward, the minimum action solution for SU(2) Yang-Mills fields in Euclidean 4-space correspond, via Penrose twistor transform, to algebraic bundles on the complex projective 3-space. Assuming dominance of correlation between the fermions on the domain walls via exchange of instantons, I extract parameters necessary for defining gauge fields of Atiyah-Ward ansatz. The QCD effective coupling in the infrared and the relation between the number of flavors and the infrared fixed point is investigated. Consequence of this lepton flavor assignment to phenomenology of baryons is also discussed. (author)

    2000-01-01

    This article analyses, after introductory comments on the legal situation in the German Empire and the Weimar Republic, the legal basis for induced abortions during National Socialist rule in Germany. During this period the first legal definition for eugenically and medically indicated abortions was established. At the same time the prohibition of induced abortions outside these criteria was controlled more strictly and violations were punished more severely. This concerned abortions mainly for social reasons. The intention was to legalize abortion for those deemed "less worthy" while, at the same time, to minimise the number of abortions of those considered as "more valuable" to society. The main thrust of this policy was to increase the birth rate of "valuable" citizens. The second part of this paper focuses on eugenic and medical abortions at the University of Freiburg's Maternity Hospital. PMID:11050762

  17. Basis set approach in the constrained interpolation profile method

    International Nuclear Information System (INIS)

    We propose a simple polynomial basis-set that is easily extendable to any desired higher-order accuracy. This method is based on the Constrained Interpolation Profile (CIP) method and the profile is chosen so that the subgrid scale solution approaches the real solution by the constraints from the spatial derivative of the original equation. Thus the solution even on the subgrid scale becomes consistent with the master equation. By increasing the order of the polynomial, this solution quickly converges. 3rd and 5th order polynomials are tested on the one-dimensional Schroedinger equation and are proved to give solutions a few orders of magnitude higher in accuracy than conventional methods for lower-lying eigenstates.

    International Nuclear Information System (INIS)

    A Molten Salt Demonstration Transmuter is required to show the operation and design performance for closing the nuclear spent fuel cycle for PWR or WWER reactors operated in the once-through cycle mode. The remnant waste would be either permanently stored or held for secondary use. The purpose of this proposal is to establish the design basis for the Molten Salt Demonstration Transmuter. It is supposed that once-through-cycle nuclear spent fuel would be delivered to the Molten Salt Demonstration Transmuter in the standard transportable container includes 84 WWER-440 SNF assemblies each weighing 250 kg and containing 120 kg U, and about 1.2 kg of Pu and minor actinides. One assembly at a time will be withdrawn from the container and chemically processed to supply Pu and minor actinides at the rate necessary for burn-up compensation. (Authors)

  19. Genetic basis of triatomine behavior: lessons from available insect genomes

    Directory of Open Access Journals (Sweden)

    Jose Manuel Latorre-Estivalis

    2013-01-01

    Full Text Available Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. In recent times, a variety of molecular genetics techniques has allowed researchers to investigate elaborate and complex questions about the genetic bases of the physiology of insects. This, together with the current characterisation of the genome sequence of Rhodnius prolixus allows the resurgence of this excellent insect physiology model in the omics era. In the present revision, we suggest that studying the molecular basis of behaviour and sensory ecology in triatomines will promote a deeper understanding of fundamental aspects of insect and, particularly, vector biology. This will allow uncovering unknown features of essential insect physiology questions for a hemimetabolous model organism, promoting more robust comparative studies of insect sensory function and cognition.

  20. The Gaussian Radial Basis Function Method for Plasma Kinetic Theory

    CERN Document Server

    Hirvijoki, Eero; Belli, Emily; Embréus, Ola

    2015-01-01

    A fundamental macroscopic description of a magnetized plasma is the Vlasov equation supplemented by the nonlinear inverse-square force Fokker-Planck collision operator [Rosenbluth et al., Phys. Rev., 107, 1957]. The Vlasov part describes advection in a six-dimensional phase space whereas the collision operator involves friction and diffusion coefficients that are weighted velocity-space integrals of the particle distribution function. The Fokker-Planck collision operator is an integro-differential, bilinear operator, and numerical discretization of the operator is far from trivial. In this letter, we describe a new approach to discretize the entire kinetic system based on an expansion in Gaussian Radial Basis functions (RBFs). This approach is particularly well-suited to treat the collision operator because the friction and diffusion coefficients can be analytically calculated. Although the RBF method is known to be a powerful scheme for the interpolation of scattered multidimensional data, Gaussian RBFs also...

  1. Climate Change: The Physical Basis and Latest Results

    2009-01-01

    The 2007 Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) concludes: "Warming in the climate system is unequivocal." Without the contribution of Physics to climate science over many decades, such a statement would not have been possible. Experimental physics enables us to read climate archives such as polar ice cores and so provides the context for the current changes. For example, today the concentration of CO2 in the atmosphere, the second most important greenhouse gas, is 28% higher than any time during the last 800,000 years. Classical fluid mechanics and numerical mathematics are the basis of climate models from which estimates of future climate change are obtained. But major instabilities and surprises in the Earth System are still unknown. These are also to be considered when the climatic consequences of proposals for geo-engineering are estimated. Only Physics will permit us to further improve our understanding in order to provide the foundation for policy decisions facing the...

  2. Best-basis analysis of broadband tremor signals

    1999-06-01

    Full Text Available Active volcanoes usually generate highly non-stationary broadband tremor signals. Short-time shock events with a frequency content of several decades are superimposed on a stationary narrow band continuous tremor. Tremor signals of this type can be observed in the near field of many active volcanoes. In this paper we will demonstrate the analysis of such signals using a specific tremor signal of Mt. Stromboli (Sicily. We used the Best-Basis Algorithm (BBA in order to compute a spectrogram which is adapted to signal properties on highly different scales. It turns out that the BBA can reveal better fitting properties of the tremor in the time-frequency plane compared to standard methods like Short-Time Fourier Transformation (STFT. Moreover, this very effective algorithm can be used for real time monitoring in the time-frequency plane, for data compression or for de-noising of the tremor signals.

  3. The genetic basis of leukaemia and clues to radiogenic causation

    International Nuclear Information System (INIS)

    Work by the author and others on the genetic basis of leukemia is briefly reviewed. The somatic changes that cause leukemia typically take the form of reciprocal translocations between non-homologous autosomes, though non-random duplications and deletions also occur. There is currently no evidence that leukemic translocations are transmitted in the germ line causing leukemia in offspring, but there is evidence that constitutional chromosomal abnormality in general is associated with an increased risk of leukemia. Hereditary effects probably increase the risk of sporadic leukemia by affecting the response to environmental hazards, through 'leukemia-predisposing genes' and 'leukemia-susceptibility genes'. Rapid progress with the techniques of population molecular screening will soon make it possible to determine the extent of hereditary contribution to sporadic leukemia in relation to histories of radiation exposure. 10 refs

  4. Location and foraging as basis for classification of biotic interactions.

    Khabibullin, Viner F

    2016-06-01

    Ecologists face an overwhelming diversity of ecological relationships in natural communities. In this paper, I propose to differentiate various types of the interspecific relations on the basis of two factors: relative localization and foraging activity of interacting partners. I advocate recognition of four types of environments: internal, surface, proximate external and distant external. Then I distinguish four types of synoikia-one partner lives in different degree of proximity to another; and four types of synmensalism: one partner forages in different degree of proximity to another. Intersection of localization-based (four subtypes of synoikia) and foraging-based (four subtypes of synmensalism) rows results in 16 types of interactions. This scheme can serve as a framework that manages diverse biotic interactions in a standardized way. I have made the first step to set up nomenclature standards for terms describing interspecific interactions and hope that this will facilitate research and communication. PMID:27160993

  5. The new legal basis of the EU's energy policy

    According to article 194 of the EU Lisbon Treaty, energy now falls within the province of European policy and is a sector for shared responsibility with member countries, in the same way as for the environment, transportation, the interior market and trans-European networks (article 4 of the Lisbon Treaty). The introduction in the Treaty of a chapter devoted to energy clearly has a political emphasis, as its shows the EU's attachment to the implementation of a coherent policy. However, its enactment carries with it not insignificant legal changes, because a specific and autonomous legal basis is established for the first time, thus allowing the Union to take decisions and actions in the area of energy.

    In decision-making under uncertainty there are two main questions that need to be evaluated: (i) What are the future consequences and associated uncertainties of an action, and (ii) what is a good (or right) decision or action. Philosophically these issues are categorized as epistemic questions (i.e. questions of knowledge) and ethical questions (i.e. questions of moral and norms). This paper discusses the second issue, and evaluates different risk management approaches for establishing good decisions, using different ethical theories as a basis. These theories include the utilitarian ethics of Bentley and Mills, and deontological ethics of Kant, Rawls and Habermas. The risk management approaches include cost-benefit analysis (CBA), minimum safety criterion, the ALARP principle and the precautionary principle.

    2006-01-01

    The philosophical principles underlying the work of Eric Kandel are investigated on the basis of his innovative paper entitled 'A new intellectual framework for psychiatry' (Kandel 1998). A careful analysis of the concepts involved reveals some ambiguity in Kandel's proposition in the mind-body debate. On the one hand Kandel uses formulations that are compatible with (classical) psychophysical identity theories; on the other hand he expresses views that actually have more in common with non-eliminative physicalism (or epiphenomenalism). In addition, he weakens his position by using misleading metaphors an analogies. This can lead to what is known as the 'mereological fallacy'. The final part of the article examines what this ambiguity tells us about Kandel's views on psychotherapy and the social justification for psychiatry. Kandel's approach can lead to a pointless narrowing down of the psychiatrist's normative role and to an over-restrictive attitude to psychotherapy. PMID:17151995

    This report concerns the development of a marking system for a nuclear waste repository which is very likely to survive for 10,000 years. In order to provide a background on the subject, and for the preliminary design presented in this report, a discussion is presented about the issues involved in human interference with the repository system and the communication of information. A separate chapter summarizes six ancient man-made monuments including: materials, effects of associated textual information on our understanding of the monument, and other features of the ancient monument relevant to marking a repository site. The information presented in the two chapters is used to provide the basis and rationale for a preliminary marker system design presented in a final chapter. 86 refs., 22 figs., 1 tab.

    Neither plate tectonics nor Earth expansion theory is sufficient to provide a basis for understanding geoscience.

A method of measuring cerebral blood volume changes during a visual activation paradigm with high temporal resolution is described in Chapter 3, and the timecourse compared to that of the BOLD response. The slow return to baseline of CBV is discussed. Chapter 4 shows a method of simultaneously measuring blood oxygenation measurements and blood volume changes. The results are shown to be in agreement with published data. The controversial phenomenon know...

    Full Text Available This study presents a survey of algorithms used in field arithmetic over GF (2m using normal basis and their hardware implementations. These include the following arithmetic field operations: addition, squaring, multiplication and inversion. This study shows that the type II Sunar-Koc multiplier is the best multiplier with a hardware complexity of m2 AND gates + XOR gates and a time complexity of TA+ (1+ l log2 (m l Tx. The study also show that the Itoh-Tsujii inversion algorithm was the best inverter and it requires almost log2 (m-1 multiplications.

    Culinary practices are influenced by climate, culture, history and geography. Molecular composition of recipes in a cuisine reveals patterns in food preferences. Indian cuisine encompasses a number of diverse sub-cuisines separated by geographies, climates and cultures. Its culinary system has a long history of health-centric dietary practices focused on disease prevention and promotion of health. We study food pairing in recipes of Indian cuisine to show that, in contrast to positive food pairing reported in some Western cuisines, Indian cuisine has a strong signature of negative food pairing; more the extent of flavor sharing between any two ingredients, lesser their co-occurrence. This feature is independent of recipe size and is not explained by ingredient category-based recipe constitution alone. Ingredient frequency emerged as the dominant factor specifying the characteristic flavor sharing pattern of the cuisine. Spices, individually and as a category, form the basis of ingredient composition in Indian...

    Full Text Available By the rising complexity and miniaturisation of the device's dimensions, the density of the conductors increases considerably. Referring to this, locally transient interactions between single physical values become apparent. Therefore, for the investigation and optimisation of integrated circuits it is essential to develop suitable models and simulation surroundings which allow for memory and time-efficient calculation of the behaviour. By means of the dynamic reconstruction theory and the radial basis functions nets the so-called black box models are provided. The description of black box models is derived from the input and output behaviour or so-called time series of a dynamic system. Concerning the time series, the black box model adapts its parameters via the extended Kalman filter. This paper provides a modelling approach that enables fast and efficient simulations.

  19. On the physical basis of pattern formation in nonlinear systems

    International Nuclear Information System (INIS)

    Spatial, respectively spatiotemporal patterns appear in a gaseous conductor (plasma) when an external constraint produces a local gradient of electron kinetic energy. Under such conditions, collective quantum effects related to the spatial separation of the excitation and ionization cross-sections determine the appearance of adjacent opposite space charges. The state of the resulting space charge configuration depends on the self-enhancement process of positive ions production, which destabilizes the system. Thus, a spatial pattern in the form of a stable double layer appears after self-organization when the above gradient is smaller than that for which the double layer transits into a moving phase (spatiotemporal pattern). The proposed explanation, based on investigations performed on self-organization phenomena observed in gaseous conductors, suggests a new possibility to clarify the challenging problems concerning the actual physical basis of pattern formation in semiconductors

    Full Text Available The aim of the study is to recognize, single out and define market segments useful for future marketing strategies, using certain statistical techniques on the basis of influence of various image factors of financial institutions. The survey included a total of 500 interviewees: 250 bank clients and 250 clients of insurance companies. Starting from the problem area and research goal, the following hypothesis has been formulated: Basic preferences of clients in regard of image factors while selecting financial institutions are different enough to be used as such for differentiating significant market segments of clients. Two segments have been singled out by cluster analysis and named, respectively, traditionalists and visualists. Results of the research confirmed the established hypothesis and pointed to the fact that managers in the financial institutions of the Federation of Bosnia and Herzegovina (FBIH must undertake certain corrective actions, especially when planning and implementing communication strategies, if they wish to maintain their competitiveness in serving both selected segments.
