    Full Text Available Resumen: En este artículo se propone una red de Petri, interpretada, estocástica, (st-IPN, como modelo para representar el lenguaje regular obtenido a partir de la combinación de señales de entrada - salida, en un sistema de eventos discretos (SED en lazo cerrado. Las señales de entrada, son las señales externas que afecten al sistema y las órdenes de control emitidas por el controlador a la planta y las señales de salida son las respuestas de los sensores a las órdenes de control. La st-IPN propuesta, es un generador determinista del lenguaje legal de sistema, capaz de representar secuencias de eventos temporizados de naturaleza estocástica. El modelo propuesto puede ser aplicado a sistemas de gran escala, a partir de la división del sistema en subsistemas, ya que el modelo global puede ser encontrado con base en la composición de los modelos de los subsistemas. Abstract: In this paper is proposed a stochastic interpreted Petri net, (st-IPN as a model to represent the regular language derived from the combination of input signals in a Discrete Event System (DES in closed loop. The input signals are external signals affecting the system and the control commands issued by the controller to the plant and the output signals are the responses of the sensors to the control commands. The st-IPN proposed is a deterministic generator of the system legal language able to represent sequences of stochastic timed events. The proposed model can be applied to large-scale systems, from the division of the system into subsystems, since the global model can be a composition of the subsystems models.

    Trains pull into a railroad station and must wait for each other before leaving again in order to let passengers change trains. How do mathematicians then calculate a railroad timetable that accurately reflects their comings and goings? One approach is to use max-plus algebra, a framework used to model Discrete Event Systems, which are well suited to describe the ordering and timing of events. This is the first textbook on max-plus algebra, providing a concise and self-contained introduction to the topic. Applications of max-plus algebra abound in the world around us.

    The methodology introduced in this article is capable of describing a binary behavior of distributed discrete event systems. This is the basis for a safety analysis in early phases of system development and for an automated determination of failure dependencies. For this purpose a system equation similar to the state-space representation in system theory is used. The equation is evaluated applying the Max-Plus/Min-Plus algebra. The procedure is exemplified by a simplified braking system. (orig.) [German] In dem vorliegenden Artikel wird ein Verfahren zur binaeren Beschreibung von verteilten ereignisdiskreten Systemen vorgestellt. Dieses wird als Grundlage fuer eine Sicherheitsanalyse in einer fruehen Phase der Systementwicklung und zur automatisierten Ermittlung von Fehlerabhaengigkeiten eingesetzt. Hierzu wird eine Systemgleichung verwendet, die aehnlich zu der Zustandsraumdarstellung der konventionellen Systemtheorie ist. Dabei erfolgt die Auswertung der Systemgleichung durch Anwendung der Max-Plus/Min-Plus Algebra. Die Vorgehensweise wird anhand des Beispiels eines vereinfachten Bremssystems erlaeutert. (orig.)

  11. Max-Plus Stochastic Control and Risk-Sensitivity

    International Nuclear Information System (INIS)

    Fleming, Wendell H.; Kaise, Hidehiro; Sheu, Shuenn-Jyi

    2010-01-01

    In the Maslov idempotent probability calculus, expectations of random variables are defined so as to be linear with respect to max-plus addition and scalar multiplication. This paper considers control problems in which the objective is to minimize the max-plus expectation of some max-plus additive running cost. Such problems arise naturally as limits of some types of risk sensitive stochastic control problems. The value function is a viscosity solution to a quasivariational inequality (QVI) of dynamic programming. Equivalence of this QVI to a nonlinear parabolic PDE with discontinuous Hamiltonian is used to prove a comparison theorem for viscosity sub- and super-solutions. An example from mathematical finance is given, and an application in nonlinear H-infinity control is sketched.

    2014-04-01

    Full Text Available Resumen: Debido a la complejidad de los procesos industriales, se necesitan diagnosticadores más sencillos y eficientes con reducción en las dimensiones de sus modelos. El diagnóstico modular ha mostrado ser eficiente en la reducción de la complejidad asociada a los sistemas de eventos discretos. Este trabajo propone un enfoque de diagnóstico basado en crónicas y análisis modular temporizado. Cada falla se asocia a un conjunto de crónicas, y cada crónica reconoce una firma de la falla, la cual es obtenida a partir de diagnosticadores de estado, modelados con autómatas de estado finito, y definidos para cada módulo del proceso. De esta manera se crea una base de crónicas modulares que luego son manipuladas a través de un protocolo de coordinación que se ejecuta en línea. El desempeño de este enfoque ha sido probado en un caso de estudio industrial relativo a una clase de sistema hidráulico, obteniendo resultados adecuados. Abstract: Nowadays industrial process systems are becoming more complex and it is needed simpler and efficient diagnosers by decreasing the dimension of their models. Modular diagnosis has proved to be very efficient in order to reduce the complexity asociated to discrete event systems. This work proposes a diagnostic approach based on chronicles and modular temporized analysis. Each fault is associated with a set of chronicles and each chronicle recognizes fault signature which is obtained from the state diagnoser associated to the finite state automata defined for each process module. A base of modular chronicles is created, which are manipulated through a coordination protocol that runs online in order to produce the global diagnosis. The performance of the proposed approach is tested on a industrial case of study and adequate results are reached.

  17. On Max-Plus Algebra and Its Application on Image Steganography

    Kiswara Agung Santoso

    2018-01-01

    Full Text Available We propose a new steganography method to hide an image into another image using matrix multiplication operations on max-plus algebra. This is especially interesting because the matrix used in encoding or information disguises generally has an inverse, whereas matrix multiplication operations in max-plus algebra do not have an inverse. The advantages of this method are the size of the image that can be hidden into the cover image, larger than the previous method. The proposed method has been tested on many secret images, and the results are satisfactory which have a high level of strength and a high level of security and can be used in various operating systems.

    2016-04-01

    Full Text Available The increasing need in techniques of storing big data presents a new challenge. One way to address this challenge is the use of distributed storage systems. One strategy that implemented in distributed data storage systems is the use of Erasure Code which applied to network coding. The code used in this technique is based on the algebraic structure which is called as vector space. Some studies have also been carried out to create code that is based on other algebraic structures such as module.  In this study, we are going to try to set up a code based on the algebraic structure which is a generalization of the module that is semimodule by utilizing the max operations and sum operations at max plus algebra. The results of this study indicate that the max operation and the addition operation on max plus algebra cannot be used to establish a semimodule code, but by modifying the operation "+" as "min", we get a code based on semimodule.

    Full Text Available El uso de modelos matemáticos como instrumentos de evaluación de alternativas está teniendo una importancia cada vez mayor en el terreno de la evaluación económica de servicios y tecnologías sanitarias, con un papel cada vez más relevante como ayuda en la toma de decisiones en la gestión sanitaria. Hasta ahora se han usado fundamentalmente 2 tipos de modelos, en parte en función de la enfermedad estudiada. De esta forma, los árboles de decisión han sido muy utilizados para las enfermedades de carácter agudo y los modelos de Markov han sido usados en enfermedades crónicas o que presentan estados de salud recurrentes. Sin embargo, tanto unos como otros presentan importantes limitaciones a la hora de modelar de forma realista ciertos procesos o enfermedades, y por ello está creciendo el interés y el uso de los modelos de simulación de eventos discretos. El objetivo del presente artículo es describir las principales características que presentan los modelos de simulación de eventos discretos, describir las últimas novedades, así como presentar qué ventajas aportan con respecto a los otros tipos de modelos en economía de la salud y, especialmente, en la evaluación económica de tecnologías y productos sanitarios.The use of mathematical models to assess therapeutic alternatives is increasing in the economic evaluation of health technologies and services and these models are becoming an increasingly important aid to decision making in health care.

However, both models present major limitations when addressing complex processes or diseases. Consequently, interest in, and the use of, discrete-event simulation is growing.

    Idempotent methods have been found to be extremely helpful in the numerical solution of certain classes of nonlinear control problems. In those methods, one uses the fact that the value function lies in the space of semiconvex functions (in the case of maximizing controllers), and approximates this value using a truncated max-plus basis expansion. In some classes, the value function is actually convex, and then one specifically approximates with suprema (i.e., max-plus sums) of affine functions. Note that the space of convex functions is a max-plus linear space, or moduloid. In extending those concepts to game problems, one finds a different function space, and different algebra, to be appropriate. Here we consider functions which may be represented using infima (i.e., min-max sums) of max-plus affine functions. It is natural to refer to the class of functions so represented as the min-max linear space (or moduloid) of max-plus hypo-convex functions. We examine this space, the associated notion of duality and min-max basis expansions. In using these methods for solution of control problems, and now games, a critical step is complexity-reduction. In particular, one needs to find reduced-complexity expansions which approximate the function as well as possible. We obtain a solution to this complexity-reduction problem in the case of min-max expansions.

    Directory of Open Access Journals (Sweden)

    Kenichi Kondo

    2013-11-01

    Full Text Available Ultradiscretization with negative values is a long-standing problem and several attempts have been made to solve it. Among others, we focus on the symmetrized max-plus algebra, with which we ultradiscretize the discrete sine-Gordon equation. Another ultradiscretization of the discrete sine-Gordon equation has already been proposed by previous studies, but the equation and the solutions obtained here are considered to directly correspond to the discrete counterpart. We also propose a noncommutative discrete analogue of the sine-Gordon equation, reveal its relations to other integrable systems including the noncommutative discrete KP equation, and construct multisoliton solutions by a repeated application of Darboux transformations. Moreover, we derive a noncommutative ultradiscrete analogue of the sine-Gordon equation and its 1-soliton and 2-soliton solutions, using the symmetrized max-plus algebra. As a result, we have a complete set of commutative and noncommutative versions of continuous, discrete, and ultradiscrete sine-Gordon equations.

    2008-05-01

    -convexity was introduced in [W. Briec, C. Horvath, -convexity, Optimization 53 (2004) 103-127]. Separation and Hahn-Banach like theorems can be found in [G. Adilov, A.M. Rubinov, -convex sets and functions, Numer. Funct. Anal. Optim. 27 (2006) 237-257] and [W. Briec, C.D. Horvath, A. Rubinov, Separation in -convexity, Pacific J. Optim. 1 (2005) 13-30]. We show here that all the basic results related to fixed point theorems are available in -convexity. Ky Fan inequality, existence of Nash equilibria and existence of equilibria for abstract economies are established in the framework of -convexity. Monotone analysis, or analysis on Maslov semimodules [V.N. Kolokoltsov, V.P. Maslov, Idempotent Analysis and Its Applications, Math. Appl., volE 401, Kluwer Academic, 1997; V.P. Litvinov, V.P. Maslov, G.B. Shpitz, Idempotent functional analysis: An algebraic approach, Math. Notes 69 (2001) 696-729; V.P. Maslov, S.N. Samborski (Eds.), Idempotent Analysis, Advances in Soviet Mathematics, Amer. Math. Soc., Providence, RI, 1992], is the natural framework for these results. From this point of view Max-Plus convexity and -convexity are isomorphic Maslov semimodules structures over isomorphic semirings. Therefore all the results of this paper hold in the context of Max-Plus convexity.

    Science.gov (United States)

    Tebani, K.; Amari, S.; Kara, R.

    2018-04-01

    In this paper, we treat the control problem of timed discrete event systems under temporal constraints. This type of constraint is very frequent in production systems, transportation network and in networked automation systems. Precisely, we are interested in the validation of strict temporal constraints imposed on the paths in a timed event graph (TEG) by using Max-Plus algebra. Not all the transitions of the considered TEG model are controllable, i.e. only the input transitions are controllable. An analytical approach for computing state feedback controllers is developed. Sufficient condition is given for the existence of causal control laws satisfying the temporal constraints. In the first, a TEG with observable transitions is considered. Then, the proposed approach is extended to the partially observable TEG. The synthesised feedback can be interpreted by places of control connected to the TEG to guarantee the respect of the time constraints. The proposed method is illustrated in the assembly system example.

    Full Text Available O turismo de eventos provoca grande atratividade econômica para as localidades receptoras, uma vez que os eventos geram fluxo programado de visitantes e o turista tem um gasto médio superior aos demais tipos de turista. Compreender os atributos que a localidade deve apresentar para ser atrativa aos organizadores e promotores de eventos é uma maneira de planejar e desenvolver o turismo em uma região. Com o objetivo de analisar os conjuntos de atributos considerados na escolha de um destino para evento, o presente estudo apresenta uma pesquisa exploratória e através de pesquisa bibliográfica indica os estudos publicados nessa temática na perspectiva dos organizadores e promotores de eventos. Foram analisados 27 artigos que discutem os atributos inerentes à tomada de decisão de destinos para eventos e descritos os 21 diferentes conjuntos de atributos identificados. Verificou-se que se pode categorizar os atributos entre os relacionados ao evento ou ao destino, sendo que estrutura para eventos, hospedagem e custos são predominantes nos estudos, enquanto existem outros atributos são considerados por autores específicos.

    Full Text Available Experimentar eventos vitales predice un deterioro en la salud , pero se desconocía si dicha experiencia afecta l a magnitud de los puntajes para cuantificar el estrés. El estudio averiguó la relación entre haber experimentado eventos vitales y su severidad . Adultos (N = 670 juzgaron la severidad de eventos que habían y que no habían experimentado . Los participantes juzgaron como más severos los eventos experimentados que los no experimentados . Esto sugirió que los puntajes empleados actualmente para cuantificar e l estrés subestiman el impacto nocivo de los eventos. Las mujeres juzgaron todos los eventos como más severos que los hombres . L os jóvenes juzgaron como más severos los eventos no experimentados mientras que las personas de clase baja juzgaron como más severos que sus contrapartes los eventos que habían experimentado. Se concluyó que la asignación de puntajes de una cierta magnitud está relacionada con experimentar los sucesos y no con las características socio -demográficas de los jueces.

    Full Text Available La infertilidad, tema de nuestro estudio, constituye un evento vital que repercute en el sistema familiar, y es considerada como una crisis familiar por desorganización. Nos propusimos realizar un estudio del evento infertilidad, para determinar su repercusión en la salud familiar y las áreas de mayor afectación, relacionándola con la adaptabilidad de la familia y el apoyo social recibido. Encontramos entre los resultados que la infertilidad como evento paranormativo presentó una repercusión en la salud familiar a un nivel leve y con un sentido desfavorable, que la infertilidad primaria tiene mayor nivel de repercusión que la secundaria, pero predomina la significación desfavorable de los 2 tipos. Las áreas de salud familiar con mayor afectación fueron la sociopsicológica y el estado de salud de los miembros con significación desfavorable; el funcionamiento familiar con significación favorable. Se encontró correspondencia entre la capacidad de adaptabilidad familiar, el apoyo social y la repercusión familiar del evento.

    Full Text Available OBJETIVO : Estimar a frequência e caracterizar os eventos adversos a medicamentos em hospital de cuidados terciários. MÉTODOS : Revisão retrospectiva de 128 prontuários de hospital do Rio de Janeiro, em 2007, representando 2.092 pacientes. A ferramenta utilizada foi uma lista de rastreadores, como antídotos, análises laboratoriais com resultados anormais, suspensão brusca de medicação e outros. Foi extraída amostra aleatória simples daqueles pacientes com 15 anos ou mais de idade. Foram excluídos pacientes oncológicos e da obstetrícia, e os internados por menos de 48 horas ou na emergência. Os pacientes com e sem eventos adversos a medicamentos foram comparados quanto a características sociais, demográficas e de doenças, para testar as diferenças entre os grupos. RESULTADOS : Cerca de 70,0% dos prontuários apresentaram no mínimo um rastreador. A capacidade dos rastreadores de identificar eventos adversos a medicamentos foi 14,4%. A incidência de eventos adversos a medicamentos foi 26,6/100 pacientes. Foram identificados um ou mais eventos em 15,6% dos pacientes. O tempo mediano de permanência hospitalar foi 35,2 dias para os pacientes com eventos adversos a medicamentos e 10,7 dias para os demais (p < 0,01. As classes de medicamentos mais envolvidos foram as que atuam sobre o aparelho cardiovascular e sobre o sistema nervoso, e os do trato digestivo e metabolismo. Os fármacos mais imputados foram: tramadol, dipirona, glibenclamida e furosemida. Do total de eventos, 82,0% contribuíram ou provocaram danos temporários ao paciente e demandaram intervenção, e 6,0% podem ter contribuído para o óbito do paciente. Estima-se que o hospital apresente, anualmente, 131 eventos de sonolência e lipotimia, 33 quedas e 33 hemorragias potencialmente associados aos medicamentos. CONCLUSÕES : Quase 1/6 dos pacientes internados apresentou um evento adverso a medicamentos (16,0%. A ferramenta estudada pode ser útil como técnica de

    With market value expected to reach 5 billion by 2007 and the endorsement of some of the biggest names in telecommunications, World Interoperability for Microwave Access (WiMAX) is poised to change the broadband wireless landscape. But how much of WiMAX's touted potential is merely hype? Now that several pre-WiMAX networks have been deployed, what are the operators saying about QoS and ROI? How and when will device manufacturers integrate WiMAX into their products? What is the business case for using WiMAX rather than any number of other established wireless alternatives?WiMAX: Taking Wireless

    2001-12-15

    A control of sliding ways in discreet time for non-linear discreet systems is designed, also the technique of the control by histograms for non-linear discreet systems was developed, and an observer of reduced order was developed for non-linear electromechanical discreet systems. All these techniques are applied to a non-linear discreet model of an induction motor that was found here, that posses electrical and mechanical dynamics, in which the load pair is considered an unknown disturbance. With complete measurements of the states are satisfied the pursuing of the rotor velocity and the amplitude of the magnetic flux of the rotor, where the unknown load does not affect the velocity regulation. Next, an observer of reduced order is implemented where the velocity and current measurements are employed to consider the load pair and the flows that are very difficult to measure. The proposed method has a design and stability procedure of direct analyses, conserving a simple structure of the control law. The simulations predict that the system is robust with respect to several types of load pairs. The responses of velocity and amplitude of the rotor flow and the entrance references evolved very well. These references have a linear dynamics of second order with time constants that can be chosen by the motor user. The practical aspects for a future digital implementation of the control law are considered, including the velocity and currents sensors, the preparation of signals, the transformation of the current in the frame of stationary reference, PWM and inverter modules, which were seen in detail. The experimental results are left as a future work.

Los datos fueron recolectados en enero de 2013 en hospital público de Fortaleza-CE, Brasil. Se aplicó entrevista semiestructurada a 37 enfermeros, incluyendo preguntas acerca de la comunicación/registro de eventos adversos. Se encontró comunicación de eventos adversos en el servicio, pero con subregistro de casos y análisis inadecuados, los enfermeros no fueron unánimes en identificar los documentos para registro de eventos, y prevalece la cultura punitiva en situaciones que generan eventos adversos, como señalan los informes de prácticas de amonestación y castigo de los profesionales. En conclusión, es necesario fomentar la comunicación adecuada de eventos adversos en el servicio, teniendo en cuenta que el registro es esencial en el proceso de comunicación organizacional, ya que es fuente de datos para análisis de eventos adversos y garantiza seguridad del paciente.

  11. Eventos organizacionais raros: O que são e como investigá-los?

    2015-02-01

    Full Text Available Eventos raros formam uma corrente de investigação relativamente negligenciada no contexto organizacional, seja por razões conceituais e/ou metodológicas. Neste artigo, apresentamos uma definição para a expressão eventos raros, quando em contexto organizacional, e uma estratégia de pesquisa para investigá-los. Utilizamos os aspectos inusitados que emergiram dos resultados de uma coleta de dados realizada no último dia de funcionamento do Cine Belas Artes (CBA de São Paulo, o qual foi obrigado a deixar o imóvel que ocupava desde sua inauguração em 19431. Por meio de uma pesquisa exploratória qualitativa, concluímos que um evento organizacional raro é um acontecimento de caráter histórico, que gera propagação em mídia e mobilização social em face de sua relevância emocional para as pessoas envolvidas na situação. Por essa definição, emergiram três perguntas norteadoras que formam uma estratégia de pesquisa para investigar eventos dessa natureza. Na dimensão teórica, esta pesquisa nos dá condições de compreender que, embora um evento acidental possa ser raro, isso não indica que todos os eventos raros são per se acidentais, já que a imprevisibilidade inerente aos aspectos que distinguem os acidentes não necessariamente caracteriza eventos raros. Quanto à prática da pesquisa, chama-se a atenção para os múltiplos aspectos envolvidos na configuração de um evento organizacional raro, o qual se revelou como um fenômeno complexo, cuja origem e assimilação de sua raridade podem assumir formas variadas. Diante desse achado de pesquisa, este estudo procura ressaltar que a abordagem de pesquisa a eventos não usuais não admite escolhas metodológicas e compreensões simplistas por parte dos pesquisadores. Acima de tudo, faz-se necessário compreender que os eventos organizacionais raros criam o desafio, tanto para as organizações como para os pesquisadores que os investigam, de encontrar maneiras

Caracteriza-se como de abordagem qualitativa exploratória e quantitativa descritiva. A amostra foi composta por 13 MH para a etapa qualitativa, onde foram realizadas entrevistas em profundidade e 54 MH para a quantitativa com os quais foram aplicados questionários online. Os principais resultados demonstram que o apoio a eventos realizados na cidade não influencia de maneira acentuada a captação de clientes. A participação em eventos do trade foi tida como uma ação de relacionamento, onde a captação de clientes é secundária. A captação de eventos para realização no hotel foi tida como a ação mais influente para o aumento da ocupação e das receitas no setor de alimentos de bebidas. Verificou-se que os eventos configuram-se como ação estratégia da comunicação de marketing para a captação de clientes.

FONTES DE DADOS: Revisão bibliográfica dos artigos (em português, inglês e espanhol obtidos dos bancos de dados eletrônicos Medline, Lilacs e SciELO, utilizando as palavras-chave: eventos com aparente risco de morte, evento com aparente risco de vida infantil, lactente, apneia, monitorização e cianose. SÍNTESE DOS DADOS: Os eventos com aparente risco de mortesão súbitos e caracterizados por uma combinação de apneia, alteração na coloração da pele e tônus muscular, com inúmeras causas subjacentes. Sua incidência verdadeira é desconhecida e a faixa etária mais acometida é de 11 a 12 semanas. Não há correlação entre o evento com aparente risco de morte e a síndrome da morte súbita do lactente, embora já tenham sido consideradas manifestações da mesma doença. Muitas vezes, o lactente tem aparência saudável ao ser avaliado pelo pediatra após apresentar eventos com aparente risco de morte, porém, isso não afasta a possibilidade de existir uma doença grave associada ao evento, que deve ser investigada e tratada. Quando não são encontradas as causas, o evento é idiopático, geralmente com boa evolução. CONCLUSÕES: É necessário investigar os lactentes levados ao pronto-socorro após apresentarem eventos com aparente risco de morte, devido ao risco de sequelas e mortalidade. Não há uma padronização das condutas a serem realizadas diante de um lactente com aparência saudável que tenha evento com aparente risco de morte, mas recomenda-se que o paciente seja internado e a causa do evento, investigada. A observação e o monitoramento em ambiente hospitalar devem ocorrer no mínimo 24 horas após o evento.OBJETIVO: Realizar una revisión crítica, reuniendo las informaciones disponibles respecto a los Eventos con Aparente Riesgo de Muerte (ALTE - Apparent life-threatening event

  16. High-Speed Computation of the Kleene Star in Max-Plus Algebraic System Using a Cell Broadband Engine

    Science.gov (United States)

    Goto, Hiroyuki

    This research addresses a high-speed computation method for the Kleene star of the weighted adjacency matrix in a max-plus algebraic system. We focus on systems whose precedence constraints are represented by a directed acyclic graph and implement it on a Cell Broadband Engine™ (CBE) processor. Since the resulting matrix gives the longest travel times between two adjacent nodes, it is often utilized in scheduling problem solvers for a class of discrete event systems. This research, in particular, attempts to achieve a speedup by using two approaches: parallelization and SIMDization (Single Instruction, Multiple Data), both of which can be accomplished by a CBE processor. The former refers to a parallel computation using multiple cores, while the latter is a method whereby multiple elements are computed by a single instruction. Using the implementation on a Sony PlayStation 3™ equipped with a CBE processor, we found that the SIMDization is effective regardless of the system's size and the number of processor cores used. We also found that the scalability of using multiple cores is remarkable especially for systems with a large number of nodes. In a numerical experiment where the number of nodes is 2000, we achieved a speedup of 20 times compared with the method without the above techniques.

    Full Text Available En las últimas décadas, hemos sido testigos de la competencia feroz entre ciudades por acoger grandes eventos, como Olimpiadas o exposiciones multitudinarias. No obstante, no siempre es aconsejable apostar por el turismo de eventos. Cuando la toma de decisiones con respecto al evento en cuestión no se basa en un serio compromiso con los objetivos estratégicos de la ciudad, su celebración no repercute positiva- mente en el territorio. Acoger un gran evento puede suponer perjuicios económicos, sociales y culturales, por lo que una cuidadosa planificación resulta indispensable. Este artículo se aproxima al caso de Expo Zaragoza.

    Full Text Available Neste texto, examinamos as condições sociais e semióticas em que a escrita se faz presente no cotidiano de uma turma da educação infantil de uma escola pública em Belo Horizonte, por meio da análise de eventos interacionais e de letramento identificados nesse contexto. Os eventos analisados integram o banco de dados de uma pesquisa que envolveu a observação participante e adotou as abordagens da etnografia interacional e da sociologia da infância no exame de como, quando e por quem atividades com a escrita eram iniciadas e desenvolvidas na turma observada. A contraposição de diferentes formas de análise e de representação da interação entre participantes em eventos de letramento evidenciou que ora a professora, ora os alunos tornavam a escrita integrante das interações estabelecidas entre eles. Além disso, foi possível reconhecer aspectos que contribuem para a ocorrência de situações de incompreensão entre os participantes do grupo. O engajamento das crianças nos eventos de letramento permite argumentar que há um esforço, individual e coletivo, das mesmas em se posicionarem como leitoras e escritoras no espaço da sala de aula.

    Donovan, E.; Spanswick, E. L.; Chicoine, R.; Pugsley, J.; Langlois, P.

    2011-12-01

    AuroraMAX is a public outreach and education initiative that brings auroral images to the public in real time. AuroraMAX utilizes an observing station located just outside Yellowknife, Canada. The station houses a digital All-Sky Imager (ASI) that collects full-colour images of the night sky every six seconds. These images are then transmitted via satellite internet to our web server, where they are made instantly available to the public. Over the last two years this program has rapidly become one of the most successful outreach programs in the history of Space Science in Canada, with hundreds of thousands of distinct visitors to the CSA AuroraMAX website, thousands of followers on social media, and hundreds of newspaper, magazine, radio, and television spots. Over the next few years, the project will expand to include a high-resolution SLR delivering real-time auroral images (also from Yellowknife), as well as a program where astronauts on the ISS will take pictures of the aurora with a handheld SLR. The objectives of AuroraMAX are public outreach and education. The ASI design, operation, and software were based on infrastructure that was developed for the highly successful ASI component of the NASA THEMIS mission as well as the Canadian Space Agency (CSA) Canadian GeoSpace Monitoring (CGSM) program. So from an education and public outreach perspective, AuroraMAX is a single camera operating in the Canadian north. On the other hand, AuroraMAX is one of nearly 40 All-Sky Imagers that are operating across North America. The AuroraMAX camera produces data that is seamlessly integrated with the CGSM ASI data, and made widely available to the Space Science community through open-access web and FTP sites. One of our objectives in the next few years is to incorporate some of the data from the THEMIS and CGSM imagers into the AuroraMAX system, to maximize viewing opportunities and generate more real-time data for public outreach. This is an exemplar of a program that

    Full Text Available Resumen: La teoría de control PID en su vertiente discreta, apoyándose en una gestión periódica de los muestreos (eventos planificados en tiempo se considera un área madura dentro del paradigma del control automático. Por el contrario, la planificación por eventos deriva, casi inevitablemente, en muestreos asíncronos planteando, problemas adicionales que necesitan ser caracterizados y estudiados. Bajo este escenario, aspectos como la sintonía de los controladores y las condiciones para la estabilidad global o la ausencia de ciclos límite siguen siendo temas que todavía están lejos de ser completamente resueltos. Con el trabajo actual se presenta un nuevo esquema de muestreo y control basado en eventos para sistemas de primer orden con retardo para el que se han analizado los aspectos anteriores. El esquema se basa en el Predictor de Smith para la compensación de los retardos, y en el algoritmo de muestreo SSOD (Symmetric Send- On-Delta para la generación de los eventos. En base a este esquema, se desarrolla el análisis de estabilidad y se propone una metodología de sintonía con una interpretación intuitiva y eficaz. Abstract: PID control theory based on periodic managing of samples has become a well-known area in automatic control. Asynchronous sampling inherent to event-based scheduling causes non-linear dynamics. Under this situation, complex problems arise that must be studied. Issues such as controller tuning, conditions for global stability and the absence of limit cycles are topics that are far from being fully solved yet. In this work, a new event-based scheme of sampling and control for FOPTD processes is presented. The scheme is based on the Smith Predictor structure for delay compensation and the SSOD (Symmetric-Send-On- Delta scheme for events generation. By means of the proposed scheme, a stability analysis is addressed and a simple tuning methodology with effective interpretation is proposed. Palabras clave

    Full Text Available Turbidity (T, FNU, discharge (Q, l/s and precipitation (P, mm are being continuously monitored in the gauging station located at the outlet of Aixola catchment (Gipuzkoa, 5 km2 since October 2003. Several data sets recorded during flood events occurred between 2003 and 2005 were used to estimate continuous suspended sediment concentration (SSC. Electrical conductivity was also measured in samples taken during runoff events. Several event (discharge, precipitation and suspended sediment concentration and pre-event (discharge and precipitation factors are calculated for all the events registered. With them a correlation matrix was developed. Good correlation between precipitation (P, discharge (Q and suspended sediment (SS variables is found in general but pre-event conditions don’t show correlation with event parameters. Analysis of SSC-discharge evolutions through the events showed that four different kinds of hysteretic loops can be observed in Aixola. Hysteretic loops have also been related to event and pre-event factors. Evolution of electrical conductivity of waters during events shows that the catchment has a considerable regulation capacity.

    La turbidez (T, FNU, el caudal (Q, l/s y la precipitación (P, mm se están midiendo en continuo en la estación de aforo situada en la salida de la cuenca de Aixola (Gipuzkoa, 5 km2 desde octubre 2003.

    Full Text Available A mechanized harvest system was analysed, working in a radiata pine clear cut operation and compound by a feller buncher, a grapple skidder, a grapple processor and a three-wheeler. A Discrete – Event Simulation Model was built with the goal to balance the system. The mechanized wood processing was the bottleneck according to the time study results, then this process was supported adding 3 chain saw felling operators to reach a yield of 60.82 m³/Productive Machine-Hour (PMH in the configuration proposal. Also the simulated skidding was done, operating the grapple skidder at 80 m Average Skidding Distance (ASD with one loading stop at a bunch for four stems to balance the obtained processing yield. Finally, the feller buncher can spend 1.6 extra minutes grouping the modify bunches to accomplish the expected yield of the system. The simulation experiment gives 60.39 m³/PMH expected yield of the system if all the proposed modifications in felling, bunching, skidding and processing are done.

    2007-12-01

    Full Text Available The basic ideas to design discrete algorithms used to calculate unmeasured mechanical or electrical variables, in order to control electrical motors in mechanical systems are presented. The main point of the paper is to simplify the algorithms by using a linear discrete time model without any variable limitations and to reduce the computing capacity requirements of the controller. Limited references, based on the discrete sliding mode for the exception of the influences of variable limitations, are proposed and designed. The main advantage of the controller presented in this paper is that a large control error does not bestow any problems. In such a case, the system always works in an area without the limitations. Original observation algorithms of both position and rotational velocity for exterior permanent magnet synchronous motors are designed. A computer simulation was performed and the results are presented, showing high dynamic accuracy.Se presentan las ideas básicas para diseñar algoritmos discretos para calcular las variables mecánicas o eléctricas, no medidas sino estimadas, para controlar motores eléctricos en sistemas mecánicos. El objetivo principal de este artículo es simplificar los algoritmos usando un modelo de tiempo discreto lineal sin ninguna limitación en las variables y reducir los requisitos de capacidad informática del controlador. Las referencias limitadas, basadas en el modo deslizante discreto para la excepción de las influencias de limitaciones de las variables, se proponen y diseñan. La ventaja principal del controlador presentada en este artículo es que un error de control grande no causa ningún problema. En dicho caso, el sistema trabaja siempre en un área sin limitaciones. Se diseñan los algoritmos de la observación originales de la posición y de la velocidad rotatoria para el imán permanente exterior de motores síncronos.

    2015-01-01

    Full Text Available Mientras que el sector de los cruceros turísticos ha sido bastante analizado por la literatura académica, las rutas regulares de cabotaje han estado poco estudiadas hasta ahora. El objetivo de este trabajo es el estudio de caso de Baleària fun&music, un programo de actividades y eventos especiales iniciado por la compañía naviera Baleària en 2012. Baleària fun&music busca usar actividades y eventos como una estrategia de diferenciación que proporcione valor añadido a sus clientes, llegando a ofrecer "minicruceros" como parte de su oferta. En las ediciones realizadas se ha producido un proceso de aprendizaje de la compañía que puede ser útil para futuras acciones similares. Por ejemplo, es recomendable organizar pocos eventos, repartidos en el tiempo y de gran impacto. Al no ser un sector con tradición en la organización de eventos, se evitan costes y riesgos al buscar patrocinadores y colaboradores para la organización de los eventos. Esta estrategia recuerda la de los trasatlánticos entre los años veinte y sesenta del siglo pasado, cuando completaban los ingresos de las líneas regulares con cruceros turísticos. Empresas de otros sectores, que no tienen los eventos como su objetivo principal, están adoptando estrategias similares.

    Full Text Available O escore de CHADS2 é um método de estratificação do risco de eventos cardiovasculares, sendo útil na decisão terapêutica em doentes de moderado/alto risco. Esta metanálise tem como objectivo averiguar se o escore de CHADS2 é eficaz na predição de eventos cerebrovasculares em doentes com Fibrilação Auricular (FA. Realizou-se uma pesquisa bibliográfica informatizada nos motores de busca PubMed, EMBASE e SciELO, durante o período de março de 2011 a abril de 2012. Os estudos foram seleccionados de acordo com critérios predeterminados. A metanálise incidiu em seis estudos de coorte, observacionais e prospectivos, que avaliaram a capacidade preditiva do escore de CHADS2 para eventos cerebrovasculares e morte. Os endpoints definidos (mortalidade e/ou Acidente Vascular Cerebral [AVC] não fatal foram comparados entre doentes com CHADS2 2, e também em função da presença/ausência de FA. No que diz respeito à ocorrência de eventos cardiovasculares combinados, morte e AVC, observou-se um maior risco no grupo com escore de CHADS2 > 2 e com FA crônica, com Odds Ratio (OR respectivamente de 2.92 (IC:2.08-4.10; p 2, independentemente da presença de FA: OR = 2.93 (IC:2.81-3.06; p < 0,00001 nos doentes com FA; OR = 2.94; (IC:2.87-3.01; p < 0,00001 nos doentes sem FA. Os estudos indicam claramente a capacidade discriminativa do escorede CHADS2 para o risco de eventos cerebrovasculares, independentemente da presença ou não de FA, permitindo desta forma identificar doentes de moderado/alto risco e seleccionar estratégias terapêuticas adequadas.

    Full Text Available Este estudo propõe investigar a consciência de patrocínio, com o objetivo de verificar como as marcas dos patrocinadores são lembradas e associadas pelos participantes após a realização de um evento no ambiente Business-to-Business, com base na proposta de Meenaghan e O'Sullivan (2013. Utilizando análise de conteúdo e análise estatística descritiva, esta pesquisa exploratório-descritiva verificou níveis relevantes de consciência de patrocínio por parte dos respondentes. Vale ressaltar que, no caso do principal patrocinador, o alto nível de consciência pode ser explicado por um processo de associação semântica que relacionou o tema do evento a ele, uma empresa que comercializa e desenvolve softwares de gestão empresarial. Ao mesmo tempo, essa forte associação pode ter diminuído a atenção e memória em relação aos demais patrocinadores. Verificou-se também que o ambushing (uma associação que um indivíduo faz entre um evento e uma marca, quando esta não está, de fato, patrocinando o referido evento esteve presente de maneira acentuada na mensuração de memória induzida, quando comparada à memória espontânea. Esses resultados evidenciam a importância de uma ampla gestão do patrocínio, por promotores e patrocinadores de eventos, dada sua importância enquanto ação estratégica de marketing para alavancar novos negócios, fidelizar clientes e incrementar a valorização de suas marcas.

    Full Text Available El objetivo de este estudio es analizar la existencia de asociación entre los impactos socioculturales generados por los eventos celebrados en localidades turísticas de Cataluña y la vocación turística de los mismos. Para ello los eventos analizados son clasificados en dos tipologías en función de si plantean objetivos turísticos en su misión y de si su programación contiene elementos adaptados a los gustos de los turistas. Los datos necesarios fueron recogidos por medio de una encuesta en línea realizada a organizadores de eventos y se basa en una muestra de 263 casos. La metodología establecida consistió en cruzar la opinión de los organizadores (impactos socioculturales percibidos de la celebración de eventos con los diferentes tipos de eventos según su vocación turística mediante tablas de contingencia y la aplicación de un test de significación. El principal resultado obtenido es la confirmación de la existencia de una relación significativa entre el impacto sociocultural y el nivel de turistificación de los eventos. En concreto, estos eventos, aportan impactos positivos sobre el sentido del lugar, la identidad y el bienestar de la comunidad donde se celebran. Los efectos positivos sobre la identidad local obtienen valores especialmente altos. En nuestra opinión, esto está relacionado con la forma en que los actores sociales de los destinos turísticos (en nuestro caso los organizadores de eventos tienden a construir la identidad incluyendo las actividades turísticas como elemento intrínseco de su manera de ser. Los eventos turísticos, que muy a menudo basan sus narraciones sobre la identidad y la historia local, se integran, por lo tanto, fácilmente en el imaginario local y son percibidos como activos con capacidad para proyectar el desarrollo social y cultural local.

    Full Text Available Deploying WiMAX through High Altitude Platform Station (HAPS system is a new means of wireless delivery method and thus attracting much the attention in a telecommunication society. However delivering WiMAX through the terrestrial network has already been started a few years ago. Therefore, we need to look at the scenario of coexistence system both of HAPS and terrestrial in delivering WiMAX services. This paper evaluates the performance of coexistence system between cellular HAPS and terrestrial for the downlink scenario when they are transmitting WiMAX mobile 802.16e services. Our evaluation is based on the performance simulation of coexistence model using two methods. First method is a footprint exchange between the two systems.The second method is a combination of footprint exchange and HAPS footprint enhancement. The proposed methodsare then evaluated by computer simulation in terms of carrier to interference plus noise ratio (CINR performance. In general, both methods resulting performance enhancement in CINR quality compared with coexistence deployment with normal scenario of the cell configuration used by HAPS and terrestrial. The method of combining footprint exchange and HAPS footprint enhancement is able to improve CINR more than 10 dB compared with the normal footprint configuration for all users location inside the coverage.

    O detector de ondas gravitacionais Mario Schenberg será sensível a sinais que cheguem à Terra com amplitude h~10-21 e dentro da faixa em frequências que varia de 3,0 a 3,4 kHz. As principais fontes astrofísicas em condições de gerar um sinal detectável pela antena Schenberg são: colapsos estelares que produzam eventos do tipo supernova; instabilidades hidrodinâmicas em estrelas de nêutrons; excitação dos modos fluído (modos f) de estrelas de nêutrons; excitação dos primeiros modos quadrupolares de buracos negros com massa ~ 3,8 M¤; coalescências de estrelas de nêutrons e buracos negros em sistemas binários e, ainda, espiralações de mini-buracos negros. Neste trabalho nós determinamos as taxas de eventos para o Schenberg associadas a dois tipos de fontes: através da de-excitação dos modos f de estrelas de nêutrons e através da coalescência de mini-buracos negros de 0,5 M¤ (que atualmente têm sido colocados como possíveis candidatos a objetos massivos do halo Galáctico). Nós mostramos que esses tipos de fontes poderão produzir sinais em ondas gravitacionais com uma taxa em torno de um evento por ano dentro da banda do Schenberg.

A despeito do crescente número de publicações nessa área, persistem lacunas de conhecimento acerca desses eventos na modalidade da assistência cirúrgica ambulatorial. Esta pesquisa objetivou estimar a incidência de eventos adversos cirúrgicos em hospital dia. Trata-se de um estudo de coorte retrospectiva de 55.879 pacientes operados num hospital dia entre os anos de 2010 e 2014. A incidência de eventos adversos cirúrgicos foi de 0,51%. Destes eventos, 0,31% foram de Infecções do sítio cirúrgico e 0,19% de outros eventos adversos cirúrgicos distribuídos proporcionalmente em: deiscência da ferida cirúrgica (12,90%, hemorragia (5,20%, flebite (5,20% e trombose dos membros inferiores (4,90%. Os resultados deste estudo ratificam que a cirurgia realizada em regime ambulatorial de hospital dia está relacionada a menores incidências de eventos adversos cirúrgicos, entretanto, é indispensável um sistema de seguimento dos pacientes após alta, no sentido de evitar a subnotificação e sub-registros dos dados, que, na ausência desse, pode ocultar dados e identificar taxas irreais. ============================================== Surgical adverse events are especially relevant because of their impact on patients’ health and because they are preventable events. Despite the growing number of publications in this area, there are still gaps in knowledge about these events in the ambulatory surgical care modality.

Os ensaios foram conduzidos em quatro regiões do país, com o híbrido DKB 390, submetido a seis tratamentos: híbrido com o evento piramidado, híbrido com o evento que expressa apenas a proteína Cry1A(b (MON 810 e híbrido convencional (não Bt, todos com e sem manejo integrado de S. frugiperda. Para o evento piramidado, não foi necessário o controle químico em nenhum dos locais avaliados. Diferenças significativas foram observadas entre os tratamentos quanto aos danos e à presença de lagartas. Em geral, essas variáveis foram mais baixas no híbrido com o evento piramidado e mais altas no híbrido convencional, sem controle químico. Sob alta infestação, o controle químico reduziu os danos causados por S. frugiperda e D. saccharalis, tanto no evento que expressa apenas uma proteína, como no híbrido convencional. Com base nos danos causados pelos insetos, o evento piramidado Cry1A.105 e Cry2Ab2 é eficiente no controle dos principais lepidópteros-pragas do milho no Brasil.

  17. O DISCURSO DO MARKETING DE LUGAR E OS GRANDES EVENTOS

    Directory of Open Access Journals (Sweden)

    Michel Nicolau Netto

    Full Text Available Os grandes eventos se globalizam na mesma medida em que proliferam os lugares promovidos como marcas. Embora autônomos, esses processos estão relacionados ao se fundarem numa visão de que os lugares devem competir na globalização e que a competição deve se dar a partir de suas imagens. Esse tipo de competição se embasa num discurso produzido por publicitários de marketing de lugar, que tanto manuseiam formas simbólicas construídas como identidades coletivas, quanto se engajam na produção de novos elementos, de forma a configurá-los, tal qual as marcas de produtos, como diferencial competitivo. Neste artigo, investigo a atuação desses publicitários, compreendidos como artífices de um “senso comum planetário” que ressignifica a imagem do lugar a partir de concepção de uma marca. Serão aqui analisados os pressupostos desse discurso, suas instâncias de legitimidade e sua relação com os grandes eventos, que devem ser entendidos como espaços de consagração e circulação do discurso do marketing de lugar.

  18. A Fast Numerical Method for Max-Convolution and the Application to Efficient Max-Product Inference in Bayesian Networks.

    Science.gov (United States)

    Serang, Oliver

    2015-08-01

    Observations depending on sums of random variables are common throughout many fields; however, no efficient solution is currently known for performing max-product inference on these sums of general discrete distributions (max-product inference can be used to obtain maximum a posteriori estimates). The limiting step to max-product inference is the max-convolution problem (sometimes presented in log-transformed form and denoted as "infimal convolution," "min-convolution," or "convolution on the tropical semiring"), for which no O(k log(k)) method is currently known. Presented here is an O(k log(k)) numerical method for estimating the max-convolution of two nonnegative vectors (e.g., two probability mass functions), where k is the length of the larger vector. This numerical max-convolution method is then demonstrated by performing fast max-product inference on a convolution tree, a data structure for performing fast inference given information on the sum of n discrete random variables in O(nk log(nk)log(n)) steps (where each random variable has an arbitrary prior distribution on k contiguous possible states). The numerical max-convolution method can be applied to specialized classes of hidden Markov models to reduce the runtime of computing the Viterbi path from nk(2) to nk log(k), and has potential application to the all-pairs shortest paths problem.

    Full Text Available Los cuidados proporcionados por el equipo de salud a los pacientes pediátricos llevan implícito el riesgo de generar errores y, por consiguiente, eventos adversos que pueden ocasionar complicaciones, secuelas o incluso la muerte. Los eventos adversos que se presentan con mayor frecuencia en el paciente pediátrico son la infección, complicaciones de catéteres y medicamentos. Las acciones preventivas se deben orientar a la sensibilización del personal, notificación de errores, adecuado clima laboral, entrenamiento, uso de técnica aséptica y una adecuada cultura. El profesional de enfermería debe reconocer la importancia de aplicar acciones preventivas para contribuir a fortalecer la calidad del cuidado en el marco de la seguridad clínica.

    The classical max-flow min-cut theorem describes transport through certain idealized classical networks. We consider the quantum analog for tensor networks. By associating an integral capacity to each edge and a tensor to each vertex in a flow network, we can also interpret it as a tensor network and, more specifically, as a linear map from the input space to the output space. The quantum max-flow is defined to be the maximal rank of this linear map over all choices of tensors. The quantum min-cut is defined to be the minimum product of the capacities of edges over all cuts of the tensor network. We show that unlike the classical case, the quantum max-flow=min-cut conjecture is not true in general. Under certain conditions, e.g., when the capacity on each edge is some power of a fixed integer, the quantum max-flow is proved to equal the quantum min-cut. However, concrete examples are also provided where the equality does not hold. We also found connections of quantum max-flow/min-cut with entropy of entanglement and the quantum satisfiability problem. We speculate that the phenomena revealed may be of interest both in spin systems in condensed matter and in quantum gravity.

    Aortic pulse waveforms are composed of a forward wave from the heart and a reflection wave from the periphery. We focused on this forward wave and suggested a new parameter, the maximum slope of aortic pulse waveforms (max dD/dt), for fetal cardiac contractility. Max dD/dt was calculated from fetal aortic pulse waveforms recorded with an echo-tracking system. A normal range of max dD/dt was constructed in 105 healthy fetuses using linear regression analysis. Twenty-two fetuses with suspected fetal cardiac dysfunction were divided into normal and decreased max dD/dt groups, and their clinical parameters were compared. Max dD/dt of aortic pulse waveforms increased linearly with advancing gestational age (r = 0.93). The decreased max dD/dt was associated with abnormal cardiotocography findings and short- and long-term prognosis. In conclusion, max dD/dt calculated from the aortic pulse waveforms in fetuses can substitute for max dP/dt, an index of cardiac contractility in adults.

    Full Text Available Uma alternativa à propaganda tradicional tem sido o Marketing Cultural através do investimento em patrocínios, ou realização de atividades culturais, já que estas permitem um maior contato das marcas com os consumidores. Este estudo analisa as percepções dos consumidores em relação as marcas investidoras em patrocínio de eventos como um dos elementos na formulação de suas estratégias de comunicação. Para isso, verifica-se a relação da participação dos consumidores em um evento cultural com a construção da imagem da marca patrocinadora. Uma vez estabelecidas essas relações, a proposição da pesquisa passa a ser a utilização do patrocínio como ferramenta estratégica na ativação da lembrança da marca na inter-relação dos valores do evento patrocinado com a imagem da marca e, por fim, na construção da imagem da marca a partir das sensações provocadas no evento. A pesquisa de campo, de natureza quantitativa, utilizou o método survey aplicado a 426 respondentes presentes em um evento cultural com dois patrocinadores master definidos, e a pesquisa de natureza qualitativa foi realizada através de três grupos focais com jovens que participaram de eventos patrocinados recentemente. Os resultados demonstram que as ações culturais podem ter impacto na percepção da imagem da marca por parte do consumidor, sendo ainda necessário que as ações sejam inéditas e que o engajamento com este público seja constante. Esta pesquisa preenche uma lacuna na literatura e traz contribuições para as empresas que desejarem utilizar o patrocínio de eventos como ferramenta do seu composto promocional.

    To assess the effect of abiraterone acetate plus prednisone on the pharmacokinetics of dextromethorphan HBr (CYP2D6 substrate) and theophylline (CYP1A2 substrate) in patients with metastatic castration-resistant prostate cancer (mCRPC). Men with progressive metastatic mCRPC who failed gonadotropin-releasing hormone therapy and ≥1 lines of chemotherapy were enrolled. Patients received two doses of dextromethorphan HBr-30 mg (n = 18; group A) or theophylline-100 mg (n = 16; group B) under fasting conditions; one dose on cycle 1, day -8, and the other dose on cycle 1, day 8. Only patients with extensive CYP2D6 metabolizing status were assigned to group A. All patients received continuous daily oral abiraterone acetate (1,000 mg) plus prednisone (10 mg) starting on cycle 1, day 1. Coadministration of abiraterone acetate plus prednisone increased the systemic exposure of dextromethorphan by approximately 100%. Ratios of geometric means for maximum plasma concentration (C(max)) (275.36%) and area under plasma concentration-time curves from time 0 to 24 h (AUC(24h)) (268.14%) of dextromethorphan were outside the bioequivalence limit. The pharmacokinetics of theophylline was unaltered following coadministration of abiraterone acetate plus prednisone. Ratios of geometric means [C(max); 102.36% and AUC(24h); 108.03%] of theophylline exposure parameters were within the bioequivalence limit. The safety profile of abiraterone acetate was consistent with reported toxicities. Abiraterone acetate plus prednisone increased the exposure of dextromethorphan, suggesting a need for caution when coadministrating with known CYP2D6 substrates. The pharmacokinetics of theophylline was unaffected when coadministered with abiraterone acetate plus prednisone.

    Full Text Available O artigo tem por objetivo oferecer aos definidores de política pública, aos governantes e aos mais diversos grupos de interesse da população brasileira conhecimentos comparativos úteis para que opinem, decidam e ajam a respeito de mega e pequenos eventos, facilitando ainda a pesquisa bibliográfica de estudantes e pesquisadores. A literatura mostra que os efeitos de um megaevento são um tema controverso. No Brasil, sede da Copa das Confederações em 2013, da Copa do Mundo em 2014 e dos Jogos Olímpicos em 2016, ainda há um importante questionamento sobre se o país, tão carente de melhorias em áreas como saúde e educação, deveria sediar megaeventos como esses. Soma-se a isso o questionamento se não seria melhor priorizar pequenos eventos nos países em geral. Os governantes e empresas interessadas na realização de megaeventos frequentemente superestimam seus efeitos positivos para a sociedade anfitriã, enquanto a literatura especializada considera que o saldo dos efeitos reais não é necessariamente positivo e, mais, tende a ser negativo. Com base nisso, desenvolveu-se e tornou-se forte a linha de entendimento de que os pequenos eventos são mais benéficos, têm maiores possibilidades de sucesso e maior potencial de efeito socioeconômico positivo – sendo assim recomendáveis no lugar de megaeventos para os países em geral, o que inclui o Brasil.

    2016-01-01

    This monograph presents a broad treatment of developments in an area of constructive approximation involving the so-called "max-product" type operators. The exposition highlights the max-product operators as those which allow one to obtain, in many cases, more valuable estimates than those obtained by classical approaches. The text considers a wide variety of operators which are studied for a number of interesting problems such as quantitative estimates, convergence, saturation results, localization, to name several. Additionally, the book discusses the perfect analogies between the probabilistic approaches of the classical Bernstein type operators and of the classical convolution operators (non-periodic and periodic cases), and the possibilistic approaches of the max-product variants of these operators. These approaches allow for two natural interpretations of the max-product Bernstein type operators and convolution type operators: firstly, as possibilistic expectations of some fuzzy variables, and secondly,...

  20. OaMAX2 of Orobanche aegyptiaca and Arabidopsis AtMAX2 share conserved functions in both development and drought responses.

    Science.gov (United States)

    Li, Weiqiang; Nguyen, Kien Huu; Watanabe, Yasuko; Yamaguchi, Shinjiro; Tran, Lam-Son Phan

    2016-09-16

    Previous studies in Arabidopsis reported that the MAX2 (more axillary growth 2) gene is a component of the strigolactone (SL) signaling pathway, which regulates a wide range of biological processes, from plant growth and development to environmental stress responses. Orobanche aegyptiaca is a harmful parasitic plant for many economically important crops. Seed germination of O. aegyptiaca is very sensitive to SLs, suggesting that O. aegyptiaca may contain components of the SL signaling pathway. To investigate this hypothesis, we identified and cloned a MAX2 ortholog from O. aegyptiaca for complementation analyses using the Arabidopsis Atmax2 mutant. The so-called OaMAX2 gene could rescue phenotypes of the Atmax2 mutant in various tested developmental aspects, including seed germination, shoot branching, leaf senescence and growth and development of hypocotyl, root hair, primary root and lateral root. More importantly, OaMAX2 could enhance the drought tolerance of Atmax2 mutant, suggesting its ability to restore the drought-tolerant phenotype of mutant plants defected in AtMAX2 function. Thus, this study provides genetic evidence that the functions of the MAX2 orthologs, and perhaps the MAX2 signaling pathways, are conserved in parasitic and non-parasitic plants. Furthermore, the results of our study enable us to develop a strategy to fight against parasitic plants by suppressing the MAX signaling, which ultimately leads to enhanced productivity of crop plants.

    Full Text Available A acirrada competição no setor educativo obriga as instituições de ensino superior privadas a reverem sua forma de gestão, pois a tradicional estratégia fragmentada, resultante do poder compartilhado e distribuído nas diversas áreas da academia, pode comprometer significativamente os resultados. As principais estratégias encontram-se de na base da pirâmide e são planejadas e executadas pelos gestores acadêmicos diante das dificuldades do cotidiano. Um dos grandes desafios vividos por organizações recém-constituídas, as startups, é organizar todos os seus projetos considerando planejamento latente e entrega simultânea. Nesse sentido, o gerenciamento de projetos tem se constituído como uma importante ferramenta de otimização de recursos e aumento da eficiência. Este artigo tem como objetivo analisar os impactos do uso de técnicas simplificadas de gestão de projetos na operação acadêmica de uma startup educacional, mais especificamente na organização de um evento, uma aula especial com um dos maiores especialista internacional na prática do marketing. Trata-se de uma pesquisa-ação que em sua fase inicial identificou diversos problemas na execução dos eventos anteriores decorrentes da ausência de um responsável e de uma metodologia que organizasse a comunicação e as tarefas, nas fases que se seguiram, o pesquisador desenvolveu e executou os processos de gerenciamento de projetos simultaneamente à realização do evento. Os resultados apontaram que o uso de técnicas de gerenciamento de projetos impactou positivamente a realização do evento, principalmente no que tange a otimização e recursos e aumento do comprometimento da equipe com a qualidade do evento.DOI:10.7769/gesec.v3i2.135

    Full Text Available ÉVÉNEMENTS MÉTÉOROLOGIQUES SÉVÈRES INDUITS PAR LES ENSO AU COURS DE LA PÉRIODE HIVERNALE À CUBA. La période hivernale à Cuba correspond généralement à la période sèche, au cours de laquelle, à l’inverse de ce qui se passe en été, on n’enregistre généralement pas de séquence pluviométrique sévère. Cependant, l’influence de l’ENSO peut activer des systèmes météorologiques de manière anormale pour des latitudes aussi basses. Il se produit alors relativement souvent des séquences météorologiques sévères de 24 à 48 heures de durée, avec l’avancée de lignes de grains, des pluies intenses, des tornades, de la grêle et des inondations dans les zones côtières. Ceci provoque des morts et de gros dégâts. Les climatologues reconnaissent l’ENSO comme la cause la plus importante de variabilité climatique inter-annuelle de la planète. Ils en décrivent et en prédisent les effets, comme les anomalies de précipitations ou de températures. Cependant on ne peut évaluer de manière plus précise ces conséquences qu’en étudiant les systèmes synoptiques induits par l’ENSO, qui sont responsables de ces excès. Cette étape est indispensable pour la mise en place d’un système d’alerte avancé requis par la Défense Civile. On montre, dans cet article, le rôle joué par le jet-stream subtropical, dans la formation de ces événements climatologiques sévères. Ainsi, l’étude des périodes hivernales affectées par un ENSO depuis 1957-58 jusqu’à 1996-97 a permis d’établir des situations types des niveaux de surface et supérieurs de l’atmosphère, associés à des événements sévères induits par l’ENSO. On présente aussi des exemples des conséquences des principaux événements. A l’aide de ces situations types, on a pu élaborer un système d’alerte avancée mis à la disposition de la Défense Civile et permettant d’effectuer des prévisions à 7 et à 10 jours.

    Full Text Available Estudo prospectivo, tipo coorte que visou identificar a influência da sobrecarga de trabalho da Enfermagem na ocorrência de incidentes sem lesão e eventos adversos em 399 pacientes internados em Unidades de Terapia Intensiva (UTI. Para coleta de dados, foi aplicado um questionário estruturado e feita análise de prontuários. Nessas admissões, aproximadamente 78% dos incidentes sem lesão e eventos adversos em pacientes foram relacionados à esfera da Enfermagem. Essas ocorrências foram atribuídas à sobrecarga de trabalho, aumentaram o número de dias de internação e o risco de óbito dos pacientes estudados. É fundamental que os gerentes de enfermagem atuem no processo de gestão de pessoas no âmbito hospitalar, evitando a sobrecarga de trabalho e proporcionando, consequentemente, aumento da segurança do paciente.

  10. ELA-max: A new topical lidocaine formulation.

    Science.gov (United States)

    Goldman, Ran D

    2004-05-01

    To evaluate the role of a new formulation of lidocaine (ELA-max) in local anesthesia in children and compare it with the eutectic mixture of local anesthetics (EMLA). Relevant literature was identified by a MEDLINE search (1966-November 2003) using the search terms ELA-max and EMLA. Bibliographies of selected articles were also examined to include all relevant investigations. The product manufacturer was contacted for inclusion of the most recent data available. Topical anesthesia in children is clinically challenging. ELA-max has been shown to be as effective as EMLA for venipuncture in children, but with faster onset. Adverse effects, such as transient blanching with redness and erythema, have been reported. Further investigation is needed to determine the effectiveness of ELA-max on other painful procedures in children, as well as its safety.

  11. Exact simulation of max-stable processes.

    Dombry, Clément; Engelke, Sebastian; Oesting, Marco

    2016-06-01

    Max-stable processes play an important role as models for spatial extreme events. Their complex structure as the pointwise maximum over an infinite number of random functions makes their simulation difficult. Algorithms based on finite approximations are often inexact and computationally inefficient. We present a new algorithm for exact simulation of a max-stable process at a finite number of locations. It relies on the idea of simulating only the extremal functions, that is, those functions in the construction of a max-stable process that effectively contribute to the pointwise maximum. We further generalize the algorithm by Dieker & Mikosch (2015) for Brown-Resnick processes and use it for exact simulation via the spectral measure. We study the complexity of both algorithms, prove that our new approach via extremal functions is always more efficient, and provide closed-form expressions for their implementation that cover most popular models for max-stable processes and multivariate extreme value distributions. For simulation on dense grids, an adaptive design of the extremal function algorithm is proposed.

    Max Planck (1858-1947) is according to the words of Max von Laue the ''father of quantum physics''. This characteristic has until today continuance, although Planck stood for long time sceptically in front of his quantum hypothesis and so became a revolutionary in spite of his wishes. Eclipted by this pioneer role of the scholar for the foundation of the quantum theory are the numerous further works of the scholer, by which he has in many other fields provided eminent things. Starting with his fundamental contribution to thermodynamics, which make him to an excellent researcher of the field, until the works in the early history of relativity theory and the promotion of the young Einstein, which let him become also to a pioneer of the second central pillar of modern physics. The present collection attempts to show the whole spectrum of the physical works of Max Planck and his role in the formation of modern physics. [de

    Full Text Available Ciudades de todo tipo en la actual jerarquía urbana se afanan por adquirir una nueva identidad. En ese proceso de reinvención urbana, el turismo de eventos deportivos ha venido desarrollando una gran capacidad para generar diferentes impactos ‘tangibles’ e ‘intangibles’, como se argumenta en este artículo con el caso de la ciudad holandesa de Utrecht y la organización del Grand Depart Tour de Francia 2015 (GDTF. Si bien se ha analizado de manera amplia el uso estratégico del Tour de Francia por parte de numerosas ciudades en la última década desde la perspectiva de la oferta, este estudio exploratorio con un carácter marcadamente internacional que incluye nueve países, uno de los cuales es España, examina el GDTF 2015 desde la perspectiva de la demanda. En particular, estudia los factores clave que pueden facilitar o condicionar el deseo de viajar, previamente al propio evento, de ciudadanos españoles a Utrecht, para seguir dicho evento. Con el fin de valorar el grado de conocimiento de los principales atractivos de la ciudad, así como las principales motivaciones de estos ciudadanos españoles a la hora de viajar a Utrecht in situ, se han utilizado encuestas, un grupo de discusión y una revisión documental. El artículo concluye con los principales resultados que se derivan de las percepciones de los ciudadanos españoles de Utrecht y su relación con el GDTF 2015, además de las implicaciones prácticas de este caso.

  4. On Tuning PI Controllers for Integrating Plus Time Delay Systems

    2010-10-01

    Full Text Available Some analytical results concerning PI controller tuning based on integrator plus time delay models are worked out and presented. A method for obtaining PI controller parameters, Kp=alpha/(k*tau, and, Ti=beta*tau, which ensures a given prescribed maximum time delay error, dtau_max, to time delay, tau, ratio parameter delta=dau_max/tau, is presented. The corner stone in this method, is a method product parameter, c=alpha*beta. Analytical relations between the PI controller parameters, Ti, and, Kp, and the time delay error parameter, delta, is presented, and we propose the setting, beta=c/a*(delta+1, and, alpha=a/(delta+1, which gives, Ti=c/a*(delta+1*tau, and Kp=a/((delta+1*k*tau, where the parameter, a, is constant in the method product parameter, c=alpha*beta. It also turns out that the integral time, Ti, is linear in, delta, and the proportional gain, Kp, inversely proportional to, delta+1. For the original Ziegler Nichols (ZN method this parameter is approximately, c=2.38, and the presented method may e.g., be used to obtain new modified ZN parameters with increased robustness margins, also documented in the paper.

    Full Text Available The IEEE 802.16 Working Group on Broadband Wireless Access Standards released IEEE 802.16-2004 which is a standardized technology for supporting broadband and wireless communication with fixed and nomadic access. After the IEEE 802.16-2004 standard, a new advanced and revised standard was released as the IEEE 802.16e-2005 amendment which is foundation of Mobile WiMAX network supporting handover and roaming capabilities. In the area of security aspects, compared to IEEE 802.16-2004, IEEE 802.16e, called Mobile WiMAX, adopts improved security architecture—PKMv2 which includes EAP authentication, AES-based authenticated encryption, and CMAC or HMAC message protection. However, there is no guarantee that PKMv2-based Mobile WiMAX network will not have security flaws. In this paper, we investigate the current Mobile WiMAX security architecture focusing mainly on pointing out new security vulnerabilities such as a disclosure of security context in network entry, a lack of secure communication in network domain, and a necessity of efficient handover supporting mutual authentication. Based on the investigation results, we propose a novel Mobile WiMAX security architecture, called RObust and Secure MobilE WiMAX (ROSMEX, to prevent the new security vulnerabilities.

    2005-01-01

    ModalMax audio speakers have been enhanced by innovative means of tailoring the vibration response of thin piezoelectric plates to produce a high-fidelity audio response. The ModalMax audio speakers are 1 mm in thickness. The device completely supplants the need to have a separate driver and speaker cone. ModalMax speakers can perform the same applications of cone speakers, but unlike cone speakers, ModalMax speakers can function in harsh environments such as high humidity or extreme wetness. New design features allow the speakers to be completely submersed in salt water, making them well suited for maritime applications. The sound produced from the ModalMax audio speakers has sound spatial resolution that is readily discernable for headset users.

    Full Text Available En este artículo pretendemos explicar el recorrido evolutivo de la línea de investigación centrada en el estudio de los eventos deportivos. Inicialmente, en los años 80 y 90, los estudios se enfocaban principalmente al análisis después del evento, del impacto que propiciaban en las ciudades y destinos que lo acogían. A la vuelta del siglo y como punto determinante en la organización de los Juegos Olímpicos de Sydney, hubo una evolución hacia un nuevo enfoque en los estudios. Aparece en la literatura una nueva perspectiva de investigación, con énfasis en la rentabilidad de los beneficios positivos de un evento. Este cuerpo de conocimiento, se basa en estudios cualitativos y analiza las estrategias más eficaces, como planearlas y como aprovecharlas para permitir que las comunidades de acogida puedan maximizar los beneficios de un evento. En este sentido, preconizamos que el aprovechamiento estratégico en la gestión de los eventos deportivos, puede contribuir a que el deporte sea un medio para mejorar la calidad de vida de las personas y la prosperidad de las comunidades.-------------------------------------------------------------In this article we explain the evolutionary path of the line of research that focuses on the study of sports events. Initially, 80’s and 90’s, studies have looked up mainly on the analysis, after the event, of the impacts that they provided in the host cities and destinations. At the turn of the century, and as a turning point in organizing the Olympic Games in Sydney, has evolved to a new approach to develope research. A new research focus appeared in the literature, with emphasis on leveraging the benefits of the event. This body of knowledge is based on qualitative studies and analyzes the most effective strategies, as well as how to plan them and exploit them to allow the host communities to maximize the benefits of an event. In this perspective, we advocate that the strategic leverage in the

En este estudio se busca explorar la dimensionalidad de la experiencia de ser voluntario en un megaevento religioso a través del concepto valor analizado con un enfoque diacrónico: pre-uso (valor esperado vs. post-uso (valor percibido. Para ello, proponemos un estudio longitudinal sobre 711 voluntarios a través de dos análisis de componentes principales diferentes, antes y después del evento, sobre las mismas escalas de las dimensiones de valor. La estructura propuesta es consistente a lo largo del tiempo y los resultados se comentan a la luz de las diferencias entre las dimensiones de valor (espiritualidad, valor social, diversión, eficiencia y tiempo/esfuerzo utilizado.

    One of the simplest and potentially most useful techniques to be developed in the 20{sup th} century, a century noted for an ever more mathematically sophisticated formulation of the sciences, is that of maximising the entropy of a system in order to generate a descriptive, stochastic model of that system in closed form, often abbreviated to MaxEnt. The extension of MaxEnt to systems beyond the physics from which it originated is hampered by the fact that the microscopic physical interactions that are not justified or justifiable within the MaxEnt framework need to be falsifiably evaluated in each new field of application. It is not obvious that such justification exists for many systems in which the interactions are not directly based on physics. For example what is the justification for the use of MaxEnt in biology, climate modelling or economics? Is it simply a useful heuristic or is there some deeper connection with the foundations of some systems? Without further critical examination of the microscopic foundations that give rise to the success of the MaxEnt principle it is difficult to motivate the use of such techniques in other fields except through theoretically an practically unsatisfying analogical arguments. This article briefly presents the basis of MaxEnt principles as originally introduced in statistical mechanics in the Jaynes form, the Tsallis form and the Rényi form. Several different applications are introduced including that of ecological diversity where maximising the different diversity measures is equivalent to maximising different entropic functionals.

Material y métodos: Serie de casos retrospectiva de 290 pacientes con cáncer de lengua, con tratamiento en el INEN, entre los años 1977 y 2000. Se excluyeron del estudio 29 pacientes tratados solo con radioterapia. De los 261 pacientes, 31 solo tuvieron tratamiento del tumor primario. Resultados: La recurrencia fue 36,8%, la recurrencia local fue la más frecuente. La incidencia acumulada de la recurrencia a los 5 años, con el método de Kaplan Meier, se estimó en 44,7%, y según el análisis de riesgos competitivos en 42,4%. En el análisis univariado considerando riesgos competitivos, las incidencias acumuladas fueron: 56,8 y 38,9% en pacientes menores o iguales que 45 y mayores que 45 años respectivamente (p = 0,1556, 29,4% y 50,5% en pacientes con ganglios patológicos negativos y positivos, respectivamente (p = 0,0002, y 37,5% en pacientes con cirugía, y 47,4% con radioterapia (p = 0,03.

Conclusiones: La pequeña diferencia entre los resultados del método Kaplan Meier y el que toma en cuenta eventos competitivos se debe a la baja tasa del evento competitivo, más aún por que se trata de muerte no relacionada con la enfermedad. La tasa de recurrencia fue similar al reportado en la literatura. Sólo se encontró diferencia significativa en la tasa de recurrencia en el grupo con compromiso ganglionar positivo.

    Full Text Available Resumo Como a borda do gelo marinho antártico está localizada em uma região muito sensível, sob a Frente Polar Antártica, existe um grande potencial da variabilidade do gelo marinho afetar a circulação atmosférica. Assim, o objetivo deste estudo foi investigar as possíveis relações entre os eventos extremos de gelo marinho antártico e as células de circulação meridional no Pacífico Sudeste, região onde há intensa variabilidade em várias escalas de tempo. Os resultados mostram que quando há eventos extremos de expansão de gelo marinho no setor do mar de Ross, existe um resfriamento da TSM, que resulta em uma atmosfera adjacente fria, aumentando os gradientes térmicos entre a borda do gelo marinho e a região de mar aberto. Os gradientes de pressão são fortalecidos, fortalecendo o cinturão circumpolar de baixas pressões e o jato polar. Assim, existe um fortalecimento do ramo ascendente da célula de Ferrel sobre o Oceano Austral, enquanto há enfraquecimento nas latitudes médias, por conservação de massa. Observamos o padrão oposto em eventos extremos de retração de gelo marinho no setor do mar de Ross e expansão no setor do mar de Weddell.

    Full Text Available Resumen: En este trabajo se aborda el diagnóstico de eventos o perturbaciones de tensión registradas en subestaciones de distribución. La aparición de dichos eventos se debe a causas diversas que van desde faltas en la red, el arranque de motores de inducción, energización de transformadores y conmutación de bancos de capacitores. Se propone la caracterización de estos eventos de tensión a partir de atributos extraídos directamente de la forma de onda, y que se relacionan con los fenómenos físicos asociados tanto con las causas de los eventos, como con su localización relativa respecto del punto de medida. Se ha estudiado la relevancia de dichos atributos mediante un análisis estadístico de la varianza (MANOVA. Los atributos más relevantes se han utilizado para la obtención de reglas de clasificación mediante algoritmos de aprendizaje automático. Los resultados fueron obtenidos empleando datos de 484 eventos reales y 38 eventos simulados. Abstract: This paper focuses on diagnosis of voltage events collected in power distribution networks. Fault networks, induction motor starting, transformer energization and capacitor bank switching cause voltage events. A characterization of voltage events using attributes directly extracted from the voltage and current waveforms is done in this paper. The used attributes are highly related with the event root-cause as well as the relative location of the event source with respect to the measurement point. The relevance of each attribute has been assessed applying a statistical analysis of variance (MANOVA. The most relevant attributes have been used as input to rule-extraction algorithms in order to extract classification rules. The results were obtained using 484 real-world and 38 synthetic voltage events.

  6. Apple F-box Protein MdMAX2 Regulates Plant Photomorphogenesis and Stress Response

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available MAX2 (MORE AXILLARY GROWTH2 is involved in diverse physiological processes, including photomorphogenesis, the abiotic stress response, as well as karrikin and strigolactone signaling-mediated shoot branching. In this study, MdMAX2, an F-box protein that is a homolog of Arabidopsis MAX2, was identified and characterized. Overexpression of MdMAX2 in apple calli enhanced the accumulation of anthocyanin. Ectopic expression of MdMAX2 in Arabidopsis exhibited photomorphogenesis phenotypes, including increased anthocyanin content and decreased hypocotyl length. Further study indicated that MdMAX2 might promote plant photomorphogenesis by affecting the auxin signaling as well as other plant hormones. Transcripts of MdMAX2 were noticeably up-regulated in response to NaCl and Mannitol treatments. Moreover, compared with the wild type, the MdMAX2-overexpressing apple calli and Arabidopsis exhibited increased tolerance to salt and drought stresses. Taken together, these results suggest that MdMAX2 plays a positive regulatory role in plant photomorphogenesis and stress response.

    A large Max Planck-based German research consortium ('MaxSynBio') was formed to investigate living systems from a fundamental perspective. The research program of MaxSynBio relies solely on the bottom-up approach to Synthetic Biology. MaxSynBio focuses on the detailed analysis and understanding of essential processes of life, via their modular reconstitution in minimal synthetic systems. The ultimate goal is to construct a basic living unit entirely from non-living components. The fundamental insights gained from the activities in MaxSynBio can eventually be utilized for establishing a new generation of biotechnological processes, which would be based on synthetic cell constructs that replace natural cells currently used in conventional biotechnology. © 2018 WILEY-VCH Verlag GmbH & Co.

  15. The use and misuse of V(c,max) in Earth System Models.

    Rogers, Alistair

    2014-02-01

    Earth System Models (ESMs) aim to project global change. Central to this aim is the need to accurately model global carbon fluxes. Photosynthetic carbon dioxide assimilation by the terrestrial biosphere is the largest of these fluxes, and in many ESMs is represented by the Farquhar, von Caemmerer and Berry (FvCB) model of photosynthesis. The maximum rate of carboxylation by the enzyme Rubisco, commonly termed V c,max, is a key parameter in the FvCB model. This study investigated the derivation of the values of V c,max used to represent different plant functional types (PFTs) in ESMs. Four methods for estimating V c,max were identified; (1) an empirical or (2) mechanistic relationship was used to relate V c,max to leaf N content, (3) V c,max was estimated using an approach based on the optimization of photosynthesis and respiration or (4) calibration of a user-defined V c,max to obtain a target model output. Despite representing the same PFTs, the land model components of ESMs were parameterized with a wide range of values for V c,max (-46 to +77% of the PFT mean). In many cases, parameterization was based on limited data sets and poorly defined coefficients that were used to adjust model parameters and set PFT-specific values for V c,max. Examination of the models that linked leaf N mechanistically to V c,max identified potential changes to fixed parameters that collectively would decrease V c,max by 31% in C3 plants and 11% in C4 plants. Plant trait data bases are now available that offer an excellent opportunity for models to update PFT-specific parameters used to estimate V c,max. However, data for parameterizing some PFTs, particularly those in the Tropics and the Arctic are either highly variable or largely absent.

    To investigate the value of {sup 18}F-fluorodeoxyglucose positron emission tomography ({sup 18}F-FDG PET/CT) to predict a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in women with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Fifty-seven consecutive women with HER2-positive breast cancer, treated with trastuzumab plus taxane-based NAC, were prospectively included. Maximum Standardized Uptake Value of the primary tumor and axillary nodes were measured at baseline (PET{sub 1}.SUV{sub max}) and after the first course of NAC (PET{sub 2}.SUV{sub max}). Tumor metabolic volumes were assessed to determine Total Lesion Glycolysis (TLG). The tumor metabolic response (ΔSUV{sub max} and ΔTLG) was calculated. In univariate analysis, negative hormonal receptor status (p = 0.04), high tumor grade (p = 0.03), and low tumor PET{sub 2}.SUV{sub max} (p = 0.001) were predictive of pCR. Tumor ΔSUV{sub max} correlated with pCR (p = 0.03), provided that tumors with low metabolic activity at baseline were excluded. ΔTLG did not correlate with pCR. In multivariate analysis, tumor PET{sub 2}.SUV{sub max} < 2.1 was the best independent predictive factor (Odds ratio =14.3; p = 0.004) with both negative and positive predictive values of 76 %. Although the metabolic features of the primary tumor did not depend on hormonal receptor status, both the baseline metabolism and early response of axillary nodes were higher if estrogen receptors were not expressed (p = 0.01 and p = 0.03, respectively). In HER2-positive breast cancer, very low tumor residual metabolism after the first cycle of NAC (SUV{sub max} < 2.1) was the main predictor of pCR. These results should be further explored in multicenter studies and incorporated into the design of clinical trials. (orig.)

    2008-01-01

    Bioelectrical impedance analysis (BIA) has been shown to be highly related to skeletal muscle mass and blood volume, both of which are important determinants of maximal oxygen uptake (V-dotO 2max ). The aim of the present study was therefore to investigate the ability of whole-body and segmental multi-frequency BIA to improve current nonexercise V-dotO 2max prediction models. Data for V-dotO 2max (mL min −1 ), anthropometry, self-reported physical activity (PA-R) and BIA were collected in 115 men and women. Multiple linear regression analysis (MLR) was used to develop the most parsimonious prediction model. Segmental BIA was not superior to whole-body measurements. Correlation coefficients between V-dotO 2max and resistance indices were significantly higher at 500 kHz compared to 50 kHz (p 2max (r = 0.89). After adjusting for age, gender and PA-R, MLR revealed that the inclusion of intracellular resistance index was slightly, but significantly (p 2max ( −1 ). In short, whole-body BIA marginally improves the accuracy of nonexercise V-dotO 2max prediction models and its advantage is most pronounced in individuals with particularly low V-dotO 2max

    Endophytic fungi are microorganisms that live within plant tissues without causing disease during part of their life cycle. With the isolation and identification of these fungi, new species are being discovered, and ecological relationships with their hosts have also been studied. In Glycine max, limited studies have investigated the isolation and distribution of endophytic fungi throughout leaves and roots. The distribution of these fungi in various plant organs differs in diversity and abundance, even when analyzed using molecular techniques that can evaluate fungal communities in different parts of the plants, such as denaturing gradient gel electrophoresis (DGGE). Our results show there is greater species richness of culturable endophytic filamentous fungi in the leaves G. max as compared to roots. Additionally, the leaves had high values for diversity indices, i.e. Simpsons, Shannon and Equitability. Conversely, dominance index was higher in roots as compared to leaves. The fungi Ampelomyces sp., Cladosporium cladosporioides, Colletotrichum gloeosporioides, Diaporthe helianthi, Guignardia mangiferae and Phoma sp. were more frequently isolated from the leaves, whereas the fungi Fusarium oxysporum, Fusarium solani and Fusarium sp. were prevalent in the roots. However, by evaluating the two communities by DGGE, we concluded that the species richness was higher in the roots than in the leaves. UPGMA analysis showed consistent clustering of isolates; however, the fungus Leptospora rubella, which belongs to the order Dothideales, was grouped among species of the order Pleosporales. The presence of endophytic Fusarium species in G. max roots is unsurprising, since Fusarium spp. isolates have been previously described as endophyte in other reports. However, it remains to be determined whether the G. max Fusarium endophytes are latent pathogens or non-pathogenic forms that benefit the plant. This study provides a broader knowledge of the distribution of the fungal

    Full Text Available On the basis of similarities and dissimilarities in the consideration of authors dealt with in Discurso de la novela española contemporánea, Francisco Caudet points out Max Aub's poetics of realism stated in both his critical studies and fiction. This essay shows that Aub's contribution to the study of Mexican and Spanish literature is outstanding, not only because of his socio-historical approach, but also because of a specific perspective. This does not mean writing a "history" of literature but rather connecting creative processes. Committed during his youth to the avant-garde, Max Aub shifts after the Civil War to a type of new realistic writing. The author highlights Max Aub's activity as a critic discussing and commenting his sources. Aub's critical essays cannot be detached from his personal ideas about literary theory and practice.

  9. Applying FDTD to the Coverage Prediction of WiMAX Femtocells

    Full Text Available Femtocells, or home base stations, are a potential future solution for operators to increase indoor coverage and reduce network cost. In a real WiMAX femtocell deployment in residential areas covered by WiMAX macrocells, interference is very likely to occur both in the streets and certain indoor regions. Propagation models that take into account both the outdoor and indoor channel characteristics are thus necessary for the purpose of WiMAX network planning in the presence of femtocells. In this paper, the finite-difference time-domain (FDTD method is adapted for the computation of radiowave propagation predictions at WiMAX frequencies. This model is particularly suitable for the study of hybrid indoor/outdoor scenarios and thus well adapted for the case of WiMAX femtocells in residential environments. Two optimization methods are proposed for the reduction of the FDTD simulation time: the reduction of the simulation frequency for problem simplification and a parallel graphics processing units (GPUs implementation. The calibration of the model is then thoroughly described. First, the calibration of the absorbing boundary condition, necessary for proper coverage predictions, is presented. Then a calibration of the material parameters that minimizes the error function between simulation and real measurements is proposed. Finally, some mobile WiMAX system-level simulations that make use of the presented propagation model are presented to illustrate the applicability of the model for the study of femto- to macrointerference.

Finalmente, algunos de los resultados teóricos se aplican al control de formaciones en un sistema de experimentación real. Abstract: Networked control systems (NCSs are spatially distributed systems in which sensors, actuators and controllers exchange information through a communication channel or network. The reduction in the amount of transmitted information has a relevant impact over the system's performance. In this regard, non-conventional communication rules, such as the event-based control, have been demonstrated to be effective. In this paper, some of these strategies are reviewed. We first focus on centralized NCSs, and then the distributed control for large-scale systems is studied.

    In this paper, we show that reconstruction of an image passed through a neural network is possible, using only the locations of the max pool activations. This was demonstrated with an architecture consisting of an encoder and a decoder. The decoder is a mirrored version of the encoder, where...... convolutions are replaced with deconvolutions and poolings are replaced with unpooling layers. The locations of the max pool switches are transmitted to the corresponding unpooling layer. The reconstruction is computed only from these switches without the use of feature values. Using only the max switch...

  17. A short period undulator for MAX

    International Nuclear Information System (INIS)

    Ahola, H.; Meinander, T.

    1992-01-01

    A hybrid undulator for generation of high brilliance synchrotron radiation in the photon energy range of 60--600 eV at the 550 MeV electron storage ring MAX in Lund, Sweden has been designed and built at the Technical Research Centre of Finland in close collaboration with MAX-lab of Lund University. At the rather modest electron energy of MAX this photon energy range can be reached only by an undulator featuring a fairly short period and the smallest possible magnetic gap. Even then, higher harmonics (up to the 13th) of the radiation spectrum must be utilized. An optimization of the magnetic design resulted in a hybrid configuration of NdFeB magnets and soft iron poles with a period of 24 mm and a minimum magnetic gap of 7--10 mm. A variable-gap vacuum chamber allows reduction of the vacuum gap from a maximum of 20 mm, needed for injection, down to 6 mm during stored beam operation. A special design of this chamber permits a magnetic gap between pole tips that is only 1 mm larger than the vacuum gap. Adequate field uniformity was ensured by calibration of magnets to equal strength at their true operating point and verification of the homogeneity of their magnetization. Magnetic measurements included Hall probe scans of the undulator field and flip coil evaluations of the field integral

    The frequency spectrum is a precious resource and scarce in the communication markets. Therefore, different techniques are adopted to utilize the available spectrum in deploying WiMAX base stations (BS) in cellular networks. In this paper several types of frequency planning techniques are illustrated, and a comprehensive comparative study between conventional frequency reuse of 1 (FR of 1) and fractional frequency reuse (FFR) is presented. These techniques are widely used in network deployment, because they employ universal frequency (using all the available bandwidth) in their base station installation/configuration within network system. This paper presents a network model of 19 base stations in order to be employed in the comparison of the aforesaid frequency planning techniques. Users are randomly distributed within base stations, users' resource mapping and their burst profile selection are based on the measured signal to interference plus-noise ratio (SINR). Simulation results reveal that the FFR has advantages over the conventional FR of 1 in various metrics. 98 % of downlink resources (slots) are exploited when FFR is applied, whilst it is 81 % at FR of 1. Data rate of FFR has been increased to 10.6 Mbps, while it is 7.98 Mbps at FR of 1. The spectral efficiency is better enhanced (1.072 bps/Hz) at FR of 1 than FFR (0.808 bps/Hz), since FR of 1 exploits all the Bandwidth. The subcarrier efficiency shows how many data bits that can be carried by subcarriers under different frequency planning techniques, the system can carry more data bits under FFR (2.40 bit/subcarrier) than FR of 1 (1.998 bit/subcarrier). This study confirms that FFR can perform better than conventional frequency planning (FR of 1) which made it a strong candidate for WiMAX BS deployment in cellular networks.

    Full Text Available In recent years, there has been a substantial increase in the number of runners, with a proportional increase in their involvement in amateur street competition. Identification of the determinants of performance in this population appears necessary for optimization of time devoted to training. The objective of this study was to ascertain the association between estimated maximal oxygen uptake (VO2max, critical velocity (CV and VO2max velocity (VVO2max and athletic performance in the 3.6 km (uphill and 10 and 21.1 km (flatland events. Twelve amateur runners (nine male, mean age 36 ± 5 years underwent five tests: 1 and 5 km race on level ground, 3.6 km race with slope (≈8%, and indirect VO2max measurement. CV was determined from the linear relationship between distance and run time on the first two tests. The subjects then took part in two official 10 km and 21.1 km (half marathon races. VVO2max was calculated from the VO2max through a metabolic equation. VO2max showed the best association with running performance in the 10 and 21.1 km events. For the uphill race, VVO2max showed a better association. Overall, the variable with the highest average association was VO2max (0.91±0.07, followed by VVO2max (0.90±0.04 and VC (0.87±0.06. This study showed strong associations between physiological variables established by low-cost, user-friendly indirect methods and running performance in the 10 and 21.1 km (flatland and 3.6 km (uphill running events.

    The OneMax problem is a standard benchmark optimisation problem for a binary search space. Recent work on applying a Bandit-Based Random Mutation Hill-Climbing algorithm to the noisy OneMax Problem showed that it is important to choose a good value for the resampling number to make a careful trade off between taking more samples in order to reduce noise, and taking fewer samples to reduce the total computational cost. This paper extends that observation, by deriving an analytical expression f...

    The more than 60 ternary carbides and nitrides, with the general formula Mn+1AXn—where n = 1, 2, or 3; M is an early transition metal; A is an A-group element (a subset of groups 13-16); and X is C and/or N—represent a new class of layered solids, where Mn+1Xn layers are interleaved with pure A-group element layers. The growing interest in the Mn+1AXn phases lies in their unusual, and sometimes unique, set of properties that can be traced back to their layered nature and the fact that basal dislocations multiply and are mobile at room temperature. Because of their chemical and structural similarities, the MAX phases and their corresponding MX phases share many physical and chemical properties. In this paper we review our current understanding of the elastic and mechanical properties of bulk MAX phases where they differ significantly from their MX counterparts. Elastically the MAX phases are in general quite stiff and elastically isotropic. The MAX phases are relatively soft (2-8 GPa), are most readily machinable, and are damage tolerant. Some of them are also lightweight and resistant to thermal shock, oxidation, fatigue, and creep. In addition, they behave as nonlinear elastic solids, dissipating 25% of the mechanical energy during compressive cycling loading of up to 1 GPa at room temperature. At higher temperatures, they undergo a brittle-to-plastic transition, and their mechanical behavior is a strong function of deformation rate.

  15. Sequence-specific DNA binding by MYC/MAX to low-affinity non-E-box motifs.

    Directory of Open Access Journals (Sweden)

    Michael Allevato

    Full Text Available The MYC oncoprotein regulates transcription of a large fraction of the genome as an obligatory heterodimer with the transcription factor MAX. The MYC:MAX heterodimer and MAX:MAX homodimer (hereafter MYC/MAX bind Enhancer box (E-box DNA elements (CANNTG and have the greatest affinity for the canonical MYC E-box (CME CACGTG. However, MYC:MAX also recognizes E-box variants and was reported to bind DNA in a "non-specific" fashion in vitro and in vivo. Here, in order to identify potential additional non-canonical binding sites for MYC/MAX, we employed high throughput in vitro protein-binding microarrays, along with electrophoretic mobility-shift assays and bioinformatic analyses of MYC-bound genomic loci in vivo. We identified all hexameric motifs preferentially bound by MYC/MAX in vitro, which include the low-affinity non-E-box sequence AACGTT, and found that the vast majority (87% of MYC-bound genomic sites in a human B cell line contain at least one of the top 21 motifs bound by MYC:MAX in vitro. We further show that high MYC/MAX concentrations are needed for specific binding to the low-affinity sequence AACGTT in vitro and that elevated MYC levels in vivo more markedly increase the occupancy of AACGTT sites relative to CME sites, especially at distal intergenic and intragenic loci. Hence, MYC binds diverse DNA motifs with a broad range of affinities in a sequence-specific and dose-dependent manner, suggesting that MYC overexpression has more selective effects on the tumor transcriptome than previously thought.

    Full Text Available Advanced engineering and functional ceramics are sensitive to damage cracks, which delay the wide applications of these materials in various fields. Ceramic composites with enhanced fracture toughness may trigger a paradigm for design and application of the brittle components. This paper reviews the toughening mechanisms for the nanolayered MAX phase ceramics. The main toughening mechanisms for these ternary compounds were controlled by particle toughening, phase-transformation toughening and fiber-reinforced toughening, as well as texture toughening. Based on the various toughening mechanisms in MAX phase, models of SiC particles and fibers toughening Ti3SiC2 are established to predict and explain the toughening mechanisms. The modeling work provides insights and guidance to fabricate MAX phase-related composites with optimized microstructures in order to achieve the desired mechanical properties required for harsh application environments.

    MOTIVATION: The task of reconstructing a genomic sequence from a particular species is gaining more and more importance in the light of the rapid development of high-throughput sequencing technologies and their limitations. Applications include not only compensation for missing data in unsequenced...... genomic regions and the design of oligonucleotide primers for target genes in species with lacking sequence information but also the preparation of customized queries for homology searches. RESULTS: We introduce the maxAlike algorithm, which reconstructs a genomic sequence for a specific taxon based...... on sequence homologs in other species. The input is a multiple sequence alignment and a phylogenetic tree that also contains the target species. For this target species, the algorithm computes nucleotide probabilities at each sequence position. Consensus sequences are then reconstructed based on a certain...

  5. Penultimate modeling of spatial extremes: statistical inference for max-infinitely divisible processes

    KAUST Repository

    Huser, Raphaël

    2018-01-09

    Extreme-value theory for stochastic processes has motivated the statistical use of max-stable models for spatial extremes. However, fitting such asymptotic models to maxima observed over finite blocks is problematic when the asymptotic stability of the dependence does not prevail in finite samples. This issue is particularly serious when data are asymptotically independent, such that the dependence strength weakens and eventually vanishes as events become more extreme. We here aim to provide flexible sub-asymptotic models for spatially indexed block maxima, which more realistically account for discrepancies between data and asymptotic theory. We develop models pertaining to the wider class of max-infinitely divisible processes, extending the class of max-stable processes while retaining dependence properties that are natural for maxima: max-id models are positively associated, and they yield a self-consistent family of models for block maxima defined over any time unit. We propose two parametric construction principles for max-id models, emphasizing a point process-based generalized spectral representation, that allows for asymptotic independence while keeping the max-stable extremal-$t$ model as a special case. Parameter estimation is efficiently performed by pairwise likelihood, and we illustrate our new modeling framework with an application to Dutch wind gust maxima calculated over different time units.

    1986-01-01

    Apple introduced the Macintosh Plus on January 16, 1986. The Macintosh Plus has an 8 MHz 68000 processor and an internal 800K floppy disk drive. It supports up to 4 MB of RAM. The Plus is a significant improvement over the previous compact Macs primarily due to the addition of the SCSI bus. Previous Macs did not have SCSI, thus making it more difficult to find a suitable external hard drive able to connect through the drive port, the printer port, or the modem port. These drives are considerably slower (as much as 4 times slower) than external SCSI hard drives. The Macintosh Plus is a very important computer in the history of the Apple Computers. It set up many of the standards that Apple followed for over a decade going forward.

Para tal fin, se proponen los modelos ARCH y sus extensiones, que son en tiempo discreto, así como un modelo empírico de volatilidad estocástica, desarrollado por Paul Wilmott. Para el caso discreto se muestran los modelos que permiten estimar la volatilidad condicional heterocedástica en un instante t del tiempo, t∈[1,T]. En el caso continuo se asocia un proceso de difusión de Itô a la volatilidad estocástica de la serie financiera, lo cual posibilita discretizar dicho proceso y simularlo para obtener densidades de probabilidad empíricas de la volatilidad.

For the discrete case, models that allow to estimate heteroscedasticity conditional volatility in a time, t, t,t∈[1,T], are shown. In the continuous case, there is an association of an Itô diffusion process to stochastic volatility of the financial series, which allows to write a discretization of this process and to simulate it to obtain empirical probabilistic densities from the volatility.

  13. Multiple variables explain the variability in the decrement in VO2max during acute hypobaric hypoxia.

    1998-06-01

    We used multiple regression analyses to determine the relationships between the decrement in sea level (SL, 760 Torr) VO2max during hypobaric hypoxia (HH) and variables that could alter or be related to the decrement in VO2max. HH conditions consisted of 682 Torr, 632 Torr, and 566 Torr, and the measured independent variables were SL-VO2max, SL lactate threshold (SL-LT), the change in hemoglobin saturation at VO2max between 760 and 566 Torr (delta SaO2max), lean body mass (LBM), and gender. Male (N = 14) and female (N = 14) subjects of varied fitness, training status, and residential altitude (1,640-2,460 m) completed cycle ergometry tests of VO2max at each HH condition under randomized and single-blinded conditions. VO2max decreased significantly from 760 Torr after 682 Torr (approximately 915 m) (3.5 +/- 0.9 to 3.4 +/- 0.8 L.min-1, P = 0.0003). Across all HH conditions, the slope of the relative decrement in VO2max (%VO2max) during HH was -9.2%/100 mm Hg (-8.1%/1000 m) with an initial decrease from 100% estimated to occur below 705 Torr (610 m). Step-wise multiple regression revealed that SL-VO2max, SL-LT, delta SaO2max, LBM, and gender each significantly combined to account for 89.03% of the variance in the decrement in VO2max (760-566 Torr) (P decrement in VO2max during HH. The unique variance explanation afforded by SL-LT, LBM, and gender suggests that issues pertaining to oxygen diffusion within skeletal muscle may add to the explanation of between subjects variability in the decrement in VO2max during HH.

  14. Eight-component retrievals from ground-based MAX-DOAS observations

    Full Text Available We attempt for the first time to retrieve lower-tropospheric vertical profile information for 8 quantities from ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS observations. The components retrieved are the aerosol extinction coefficients at two wavelengths, 357 and 476 nm, and NO2, HCHO, CHOCHO, H2O, SO2, and O3 volume mixing ratios. A Japanese MAX-DOAS profile retrieval algorithm, version 1 (JM1, is applied to observations performed at Cabauw, the Netherlands (51.97° N, 4.93° E, in June–July 2009 during the Cabauw Intercomparison campaign of Nitrogen Dioxide measuring Instruments (CINDI. Of the retrieved profiles, we focus here on the lowest-layer data (mean values at altitudes 0–1 km, where the sensitivity is usually highest owing to the longest light path. In support of the capability of the multi-component retrievals, we find reasonable overall agreement with independent data sets, including a regional chemical transport model (CHIMERE and in situ observations performed near the surface (2–3 m and at the 200-m height level of the tall tower in Cabauw. Plumes of enhanced HCHO and SO2 were likely affected by biogenic and ship emissions, respectively, and an improvement in their emission strengths is suggested for better agreement between CHIMERE simulations and MAX-DOAS observations. Analysis of air mass factors indicates that the horizontal spatial representativeness of MAX-DOAS observations is about 3–15 km (depending mainly on aerosol extinction, comparable to or better than the spatial resolution of current UV-visible satellite observations and model calculations. These demonstrate that MAX-DOAS provides multi-component data useful for the evaluation of satellite observations and model calculations and can play an important role in bridging different data sets having different spatial resolutions.

    Sifaou, Houssem

    2016-08-11

    This work focuses on large scale multi-user MIMO systems in which the base station (BS) outfitted with M antennas communicates with K single antenna user equipments (UEs). In particular, we aim at designing the linear precoder and receiver that maximizes the minimum signal-to-interference-plus-noise ratio (SINR) subject to a given power constraint. To gain insights into the structure of the optimal precoder and receiver as well as to reduce the computational complexity for their implementation, we analyze the asymptotic regime where M and K grow large with a given ratio and make use of random matrix theory (RMT) tools to compute accurate approximations. Although simpler, the implementation of the asymptotic precoder and receiver requires fast inversions of large matrices in every coherence period. To overcome this issue, we apply the truncated polynomial expansion (TPE) technique to the precoding and receiving vector of each UE and make use of RMT to determine the optimal weighting coefficients that asymptotically solve the max-min SINR problem. Numerical results are used to show that the proposed TPE-based precoder and receiver almost achieve the same performance as the optimal ones while requiring a lower complexity.

    1992-01-01

    We have applied the V/V(max) test to candidate gamma-ray bursts detected by the Gamma-Ray Spectrometer (GRS) aboard the SMM satellite to examine quantitatively the uniformity of the burst source population. For a sample of 132 candidate bursts identified in the GRS data by an automated search using a single uniform trigger criterion we find average V/V(max) = 0.40 +/- 0.025. This value is significantly different from 0.5, the average for a uniform distribution in space of the parent population of burst sources; however, the shape of the observed distribution of V/V(max) is unusual and our result conflicts with previous measurements. For these reasons we can currently draw no firm conclusion about the distribution of burst sources.

  19. A Modified MinMax k-Means Algorithm Based on PSO.

    Science.gov (United States)

    Wang, Xiaoyan; Bai, Yanping

    The MinMax k -means algorithm is widely used to tackle the effect of bad initialization by minimizing the maximum intraclustering errors. Two parameters, including the exponent parameter and memory parameter, are involved in the executive process. Since different parameters have different clustering errors, it is crucial to choose appropriate parameters. In the original algorithm, a practical framework is given. Such framework extends the MinMax k -means to automatically adapt the exponent parameter to the data set. It has been believed that if the maximum exponent parameter has been set, then the programme can reach the lowest intraclustering errors. However, our experiments show that this is not always correct. In this paper, we modified the MinMax k -means algorithm by PSO to determine the proper values of parameters which can subject the algorithm to attain the lowest clustering errors. The proposed clustering method is tested on some favorite data sets in several different initial situations and is compared to the k -means algorithm and the original MinMax k -means algorithm. The experimental results indicate that our proposed algorithm can reach the lowest clustering errors automatically.

    2014-01-06

    Analysis of spatial extremes is currently based on univariate processes. Max-stable processes allow the spatial dependence of extremes to be modelled and explicitly quantified, they are therefore widely adopted in applications. For a better understanding of extreme events of real processes, such as environmental phenomena, it may be useful to study several spatial variables simultaneously. To this end, we extend some theoretical results and applications of max-stable processes to the multivariate setting to analyze extreme events of several variables observed across space. In particular, we study the maxima of independent replicates of multivariate processes, both in the Gaussian and Student-t cases. Then, we define a Poisson process construction in the multivariate setting and introduce multivariate versions of the Smith Gaussian extremevalue, the Schlather extremal-Gaussian and extremal-t, and the BrownResnick models. Inferential aspects of those models based on composite likelihoods are developed. We present results of various Monte Carlo simulations and of an application to a dataset of summer daily temperature maxima and minima in Oklahoma, U.S.A., highlighting the utility of working with multivariate models in contrast to the univariate case. Based on joint work with Simone Padoan and Huiyan Sang.

    Firmware for FPGA trigger applications at the CMS experiment is conventionally written using hardware description languages such as Verilog and VHDL. MaxCompiler is an alternative, Java based, tool for developing FPGA applications which uses a higher level of abstraction from the hardware than a hardware description language. An implementation of the jet and energy sum algorithms for the CMS Level-1 calorimeter trigger has been written using MaxCompiler to benchmark against the VHDL implementation in terms of accuracy, latency, resource usage, and code size. A Kalman Filter track fitting algorithm has been developed using MaxCompiler for a proposed CMS Level-1 track trigger for the High-Luminosity LHC upgrade. The design achieves a low resource usage, and has a latency of 187.5 ns per iteration.

    When detached soybean Glycine max (L.) Merr. cv. Hark, nodules assimilate ( 13 N)N 2 , the initial organic product of fixation is glutamine; glutamate becomes more highly radioactive than glutamine within 1 minute; 13 N in alanine becomes detectable at 1 minute of fixation and increases rapidly between 1 and 2 minutes. After 15 minutes of fixation, the major 13 N-labeled organic products in both detached and attached nodules are glutamate and alanine, plus, in the case of attached nodules, an unidentified substance, whereas ( 13 N)glutamine comprises only a small fraction of organic 13 N, and very little 13 N is detected in asparagine. The fixation of ( 13 N)N 2 into organic products was inhibited more than 99 percent by C 2 H 2 (10 percent, v/v). The results support the idea that the glutamine synthetase-glutamate synthase pathway is the primary route for assimilation of fixed nitrogen in soybean nodules

    Full Text Available La función de un transformador es cambiar el nivel de tensión a través de un acoplamiento magnético. Debido a su construcción física, su representación como un circuito y su modelo matemático son muy complejos. El comportamiento electromagnético del transformador, al igual que todos los elementos de la red eléctrica de potencia, depende de la frecuencia involucrada. Por esta razón cuando se tienen fenómenos de alta frecuencia su modelo debe ser muy detallado para que reproduzca el comportamientodel estado transitorio. En este trabajo se analiza cómo se pasa de un modelo muy simple, a un modelo muy detallado para hacer simulación de eventos de alta frecuencia. Los eventos que se simulan son la operación de un interruptor por una falla en el sistema y el impacto de una descarga atmosférica sobre la línea de transmisión a una distancia de 5 km de una subestación de potencia. The transformer’s function is to change the voltage level through a magnetic coupling. Due to its physical construction, its representation as a circuit and its mathematical model are very complex. The electromagnetic behavior and all the elements in the power network depend on the involved frequency. So, for high frequency events, its model needs to be very detailed to reproduce the electromagnetic transient behavior. This work analyzes how to pass from a simple model to a very detailed model to simulated high frequency events. The simulated events are the switch operation due to a fault in the system and the impact of an atmospheric discharge (direct stroke in the transmission line, five km far away from the substation.

    In the VINDOBONA (VIenna horizontal aNd vertical Distribution OBservations Of Nitrogen dioxide and Aerosols) project, two Multi AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) systems will be set up at two different locations and altitudes in Vienna, Austria. After comparison measurements in Bremen, Germany, and Cabauw, The Netherlands, the first of the two MAX-DOAS instruments was set up at the University of Veterinary Medicine in the northeastern part of Vienna in December 2016. The instrument performs spectral measurements of visible scattered sunlight at defined horizontal and vertical viewing directions. From these measurements, column densities of NO2 and aerosols are derived by applying the DOAS analysis. First preliminary results are presented. The second MAX-DOAS instrument will be set up in April/May 2017 at the University of Natural Resources and Life Sciences in the northwestern part of Vienna. Once these two instruments are measuring simultaneously, small campaigns including car DOAS zenith-sky and tower DOAS off-axis measurements are planned. The main emphasis of this project will be on the installation and operation of two MAX-DOAS instruments, the improvement of tropospheric NO2 and aerosol retrieval, and the characterization of the horizontal, vertical, and temporal variations of tropospheric NO2 and aerosols in Vienna, Austria.

    Mitochondrial background has been demonstrated to influence maximal oxygen uptake (VO(2max), in mLkg(-1)min(-1)), but this genetic influence can be compensated for by regular exercise. A positive correlation among electron transport chain (ETC) coupling, ATP and reactive oxygen species (ROS) production has been established, and mitochondrial variants have been reported to show differences in their ETC performance. In this study, we examined in detail the VO(2max) differences found among mitochondrial haplogroups. We recruited 81 healthy male Spanish Caucasian individuals and determined their mitochondrial haplogroup. Their VO(2max) was determined using incremental cycling exercise (ICE). VO(2max) was lower in J than in non-J haplogroup individuals (P=0.04). The H haplogroup was responsible for this difference (VO(2max); J vs. H; P=0.008) and this group also had significantly higher mitochondrial oxidative damage (mtOD) than the J haplogroup (P=0.04). In agreement with these results, VO(2max) and mtOD were positively correlated (P=0.01). Given that ROS production is the major contributor to mtOD and consumes four times more oxygen per electron than the ETC, our results strongly suggest that ROS production is responsible for the higher VO(2max) found in the H variant. These findings not only contribute to a better understanding of the mechanisms underneath VO(2max), but also help to explain some reported associations between mitochondrial haplogroups and mtOD with longevity, sperm motility, premature aging and susceptibility to different pathologies.

    Full Text Available OBJETIVO: Antibióticos são os medicamentos que mais causam eventos adversos, gerando problemas aos pacientes e custos adicionais ao sistema de saúde. Assim, objetivou-se analisar a ocorrência de eventos adversos a antibióticos em pacientes internados em um hospital. MÉTODOS: Realizou-se monitoramento intensivo do uso de antibióticos em pacientes adultos internados no município de Maringá, Paraná, de setembro de 2002 a fevereiro de 2003. Foram pesquisadas variáveis relativas aos medicamentos em uso, em particular aos antibióticos e aos eventos adversos. Com base em critérios para a avaliação do uso correto dos antibióticos, os eventos observados foram classificados como reações adversas, erros de medicação e "quase erros". Para relação de causalidade entre a administração do fármaco e o surgimento dos eventos utilizou-se o algoritmo de Naranjo. RESULTADOS: Foram acompanhados 87 pacientes e identificados 91 eventos adversos, sendo três deles (3,3% reações adversas a medicamentos, sete (7,7% erros de medicação, e 81 (89,0% "quase erros". As reações a medicamentos ocorreram devido ao uso de quinolonas e foram consideradas "prováveis" utilizando-se o algoritmo de Naranjo. Os sete erros de medicação ocorreram devido a quatro prescrições incorretas de dose e três interações medicamentosas. CONCLUSÕES: Os resultados sugerem que a falta de conhecimento do medicamento ou a falta de informação sobre o paciente no momento da prescrição tenham sido os principais fatores envolvidos na ocorrência das reações a medicamentos.OBJECTIVE: Antibiotics are the most common drugs causing adverse events and they lead to problems to patients and additional costs of the health system.

    EnergyPlus is a new generation building performance simulation program offering many new modeling capabilities and more accurate performance calculations integrating building components in sub-hourly time steps. However, EnergyPlus runs much slower than the current generation simulation programs. This has become a major barrier to its widespread adoption by the industry. This paper analyzed EnergyPlus run time from comprehensive perspectives to identify key issues and challenges of speeding up EnergyPlus: studying the historical trends of EnergyPlus run time based on the advancement of computers and code improvements to EnergyPlus, comparing EnergyPlus with DOE-2 to understand and quantify the run time differences, identifying key simulation settings and model features that have significant impacts on run time, and performing code profiling to identify which EnergyPlus subroutines consume the most amount of run time. This paper provides recommendations to improve EnergyPlus run time from the modeler?s perspective and adequate computing platforms. Suggestions of software code and architecture changes to improve EnergyPlus run time based on the code profiling results are also discussed.

    Full Text Available Transmission Control Protocol (TCP is a protocol that works at the transport layer of the OSI model. TCP was originally designed more destined for a wired network. However, to meet the need for the development of a very fast network technology based on the needs of the use by the user, it needs further development to the use of TCP on wireless devices. One implementation of a wireless network based on Worldwide Interoperability for Microwave Access (WiMAX network is a model that offers a variety advantage, particularly in terms of access speed. In this case, use NS-2 to see throughput at TCP variants tested, namely TCP-Tahoe, TCP-Reno, TCP-Vegas, and TCP-SACK over WiMAX network model, with few observations scenarios. The first is a look at each of these variants throughput of TCP when only one particular variant of the work in the network. Second observe all variants of TCP throughput at the same time and have the equivalent QoS, but with the possibility of a small congestion based on the capacity of the link is made sufficient. Third observed throughput with multi congestion. In WiMAX network has scheduling services are UGS, rtPS and ertPS using UDP protocol and nrtPS and BE using the TCP Protocol. By using the software network simulator (NS-2 to obtain performance comparison TCP protocol-based services on the WiMAX network with QoS parameters are throughput, packet loss, fairness and time delay.

    In recent years, ground-based multi-axis differential absorption spectroscopy (MAX-DOAS) has shown to be ideally suited for the retrieval of tropospheric trace gases and deriving information on the aerosol properties. These measurements are invaluable to our understanding of the physics and chemistry of the atmospheric system, and the impact on the Earth's climate. Unfortunately, MAX-DOAS measurements are often performed under strong non-clear-sky conditions, causing strong data quality degradation and uncertainties on the retrievals. Here we present the result of our cloud-screening method, using the colour index (CI), on aerosol retrievals from MAX-DOAS measurements (AOD and vertical profiles). We focus on two large data sets, from the Brussels and Beijing area. Using the CI we define 3 different sky conditions: bad (=full thick cloud cover/extreme aerosols), mediocre (=thin clouds/aerosols) and good (=clear sky). We also flag the presence of broken/scattered clouds. We further compare our cloud-screening method with results from cloud-cover fractions derived from thermic infrared measurements. In general, our method shows good results to qualify the sky and cloud conditions of MAX-DOAS measurements, without the need for other external cloud-detection systems. Removing data under bad-sky and broken-cloud conditions results in a strongly improved agreement, in both correlation and slope, between the MAX-DOAS aerosol retrievals and data from other instruments (e.g. AERONET, Brewer). With the improved AOD retrievals, the seasonal and diurnal variations of the aerosol content and vertical distribution at both sites can be investigated in further detail. By combining with additional information derived by other instruments (Brewer, lidar, ...) operated at the stations, we will further study the observed aerosol characteristics, and their influence on and by meteorological conditions such as clouds and/or the boundary layer height.

  5. QoS Management and Control for an All-IP WiMAX Network Architecture: Design, Implementation and Evaluation

    2008-01-01

    Full Text Available The IEEE 802.16 standard provides a specification for a fixed and mobile broadband wireless access system, offering high data rate transmission of multimedia services with different Quality-of-Service (QoS requirements through the air interface. The WiMAX Forum, going beyond the air interface, defined an end-to-end WiMAX network architecture, based on an all-IP platform in order to complete the standards required for a commercial rollout of WiMAX as broadband wireless access solution. As the WiMAX network architecture is only a functional specification, this paper focuses on an innovative solution for an end-to-end WiMAX network architecture offering in compliance with the WiMAX Forum specification. To our best knowledge, this is the first WiMAX architecture built by a research consortium globally and was performed within the framework of the European IST project WEIRD (WiMAX Extension to Isolated Research Data networks. One of the principal features of our architecture is support for end-to-end QoS achieved by the integration of resource control in the WiMAX wireless link and the resource management in the wired domains in the network core. In this paper we present the architectural design of these QoS features in the overall WiMAX all-IP framework and their functional as well as performance evaluation. The presented results can safely be considered as unique and timely for any WiMAX system integrator.

  6. The Dangers of Estimating V˙O2max Using Linear, Nonexercise Prediction Models.

    Nevill, Alan M; Cooke, Carlton B

    2017-05-01

    This study aimed to compare the accuracy and goodness of fit of two competing models (linear vs allometric) when estimating V˙O2max (mL·kg·min) using nonexercise prediction models. The two competing models were fitted to the V˙O2max (mL·kg·min) data taken from two previously published studies. Study 1 (the Allied Dunbar National Fitness Survey) recruited 1732 randomly selected healthy participants, 16 yr and older, from 30 English parliamentary constituencies. Estimates of V˙O2max were obtained using a progressive incremental test on a motorized treadmill. In study 2, maximal oxygen uptake was measured directly during a fatigue limited treadmill test in older men (n = 152) and women (n = 146) 55 to 86 yr old. In both studies, the quality of fit associated with estimating V˙O2max (mL·kg·min) was superior using allometric rather than linear (additive) models based on all criteria (R, maximum log-likelihood, and Akaike information criteria). Results suggest that linear models will systematically overestimate V˙O2max for participants in their 20s and underestimate V˙O2max for participants in their 60s and older. The residuals saved from the linear models were neither normally distributed nor independent of the predicted values nor age. This will probably explain the absence of a key quadratic age term in the linear models, crucially identified using allometric models. Not only does the curvilinear age decline within an exponential function follow a more realistic age decline (the right-hand side of a bell-shaped curve), but the allometric models identified either a stature-to-body mass ratio (study 1) or a fat-free mass-to-body mass ratio (study 2), both associated with leanness when estimating V˙O2max. Adopting allometric models will provide more accurate predictions of V˙O2max (mL·kg·min) using plausible, biologically sound, and interpretable models.

    It is well known that the evolution of 4G-based mobile multimedia network systems will contribute significantly to future mobile healthcare (m-health) applications that require high bandwidth and fast data rates. Central to the success of such emerging applications is the compatibility of broadband networks, such as mobile Worldwide Interoperability For Microwave Access (WiMAX) and High-Speed Uplink Packet Access (HSUPA), and especially their rate adaption issues combined with the acceptable real-time medical quality of service requirements. In this paper, we address the relevant challenges of cross-layer design requirements for real-time rate adaptation of ultrasound video streaming in mobile WiMAX and HSUPA networks. A comparative performance analysis of such approach is validated in two experimental m-health test bed systems for both mobile WiMAX and HSUPA networks. The experimental results have shown an improved performance of mobile WiMAX compared to the HSUPA using the same cross-layer optimization approach.

  12. [Psychiatry as cultural science: considerations following Max Weber].

    Science.gov (United States)

    Bormuth, M

    2010-11-01

    Psychiatry can be seen as a natural and cultural science. According to this the postulate of freedom is its strong value judgment. Since the times of enlightenment it has been described metaphorically by the myth of the expulsion from Paradise. Following Max Weber and Wilhelm Dilthey, Karl Jaspers has introduced this perspective into psychiatry. His strict dichotomy between explaining and understanding has later been critically revised by Werner Janzarik and Hans Heimann. Their concepts of structure dynamic, of pathography and of anthropology are closer to Max Weber who connected natural and cultural sciences in a much stronger way. Especially the pathographic example of Nietzsche allows to demonstrate the differences between Jaspers and the later psychopathologists of the Heidelberg and Tübingen schools.

    2007-07-01

    The max-sum labeling problem, defined as maximizing a sum of binary (i.e., pairwise) functions of discrete variables, is a general NP-hard optimization problem with many applications, such as computing the MAP configuration of a Markov random field. We review a not widely known approach to the problem, developed by Ukrainian researchers Schlesinger et al. in 1976, and show how it contributes to recent results, most importantly, those on the convex combination of trees and tree-reweighted max-product. In particular, we review Schlesinger et al.'s upper bound on the max-sum criterion, its minimization by equivalent transformations, its relation to the constraint satisfaction problem, the fact that this minimization is dual to a linear programming relaxation of the original problem, and the three kinds of consistency necessary for optimality of the upper bound. We revisit problems with Boolean variables and supermodular problems. We describe two algorithms for decreasing the upper bound. We present an example application for structural image analysis.

    Firmware for FPGA trigger applications at the CMS experiment is conventionally written using hardware description languages such as Verilog and VHDL. MaxCompiler is an alternative, Java based, tool for developing FPGA applications which uses a higher level of abstraction from the hardware than a hardware description language. An implementation of the jet and energy sum algorithms for the CMS Level-1 calorimeter trigger has been written using MaxCompiler to benchmark against the VHDL implementation in terms of accuracy, latency, resource usage, and code size. A Kalman Filter track fitting algorithm has been developed using MaxCompiler for a proposed CMS Level-1 track trigger for the High-Luminosity LHC upgrade. The design achieves a low resource usage, and has a latency of 187.5 ns per iteration.

  18. Relationship between running kinematic changes and time limit at vVO2max

    2012-06-01

    Exhaustive running at maximal oxygen uptake velocity (vVO2max can alter running kinematic parameters and increase energy cost along the time. The aims of the present study were to compare characteristics of ankle and knee kinematics during running at vVO2max and to verify the relationship between changes in kinematic variables and time limit (Tlim. Eleven male volunteers, recreational players of team sports, performed an incremental running test until volitional exhaustion to determine vVO2max and a constant velocity test at vVO2max. Subjects were filmed continuously from the left sagittal plane at 210 Hz for further kinematic analysis. The maximal plantar flexion during swing (p<0.01 was the only variable that increased significantly from beginning to end of the run. Increase in ankle angle at contact was the only variable related to Tlim (r=0.64; p=0.035 and explained 34% of the performance in the test. These findings suggest that the individuals under study maintained a stable running style at vVO2max and that increase in plantar flexion explained the performance in this test when it was applied in non-runners.

    2016-08-01

    This study continues the work of Clémer et al., (2010) and is aimed to improve trace gas retrievals with mini MAX-DOAS measurements in Nanjing. Based on that work, aerosol extinction vertical profiles are retrieved using the bePRO inversion algorithm developed by the Royal Belgian Institute for Space Aeronomy (BIRA- IASB). Afterwards, the tropospheric trace gas vertical profiles and vertical column densities (VCDs) are retrieved by applying the optimal estimation method to the O4 MAX-DOAS measurements. The Profiles for N O2 , S O2 , glyoxal, formaldehyde and nitrous acid are obtained with different results and different settings for the DOAS measurement. The AODs show small positive correlation against the AERONET values. For NO2, the retrieval shows reasonable concentrations in winter as opposed to summer and has small positive correlations with GOME-2 data. The SO2 VCDs are not correlated with the GOME-2 data, due to high uncertainties from MAX-DOAS and satellite retrievals, while the vertical mixing ratios (VMR) show good agreement with in-situ data (SORPES) at Nanjing. Nitrous acid shows a maximum in winter and a minimum in summer, while glyoxal has its maximum in August and September.

    Paproth, C.; Schlüßler, E.; Scherbaum, P.; Börner, A.

    2012-07-01

    During the development process of a remote sensing system, the optimization and the verification of the sensor system are important tasks. To support these tasks, the simulation of the sensor and its output is valuable. This enables the developers to test algorithms, estimate errors, and evaluate the capabilities of the whole sensor system before the final remote sensing system is available and produces real data. The presented simulation concept, SENSOR&plus;&plus;, consists of three parts. The first part is the geometric simulation which calculates where the sensor looks at by using a ray tracing algorithm. This also determines whether the observed part of the scene is shadowed or not. The second part describes the radiometry and results in the spectral at-sensor radiance from the visible spectrum to the thermal infrared according to the simulated sensor type. In the case of earth remote sensing, it also includes a model of the radiative transfer through the atmosphere. The final part uses the at-sensor radiance to generate digital images by using an optical and an electronic sensor model. Using SENSOR&plus;&plus; for an optimization requires the additional application of task-specific data processing algorithms. The principle of the simulation approach is explained, all relevant concepts of SENSOR&plus;&plus; are discussed, and first examples of its use are given, for example a camera simulation for a moon lander. Finally, the verification of SENSOR&plus;&plus; is demonstrated.

  4. Johnson-Cook Strength Model Constants for VascoMax 300 and 1080 Steels

    2006-01-01

    High strength steels, VascoMax 300 and 1080, are characterized under tension at strain rates of ∼1/s, ∼500/s, ∼1000/s, and ∼1500/s and at high temperatures using the quasi-static and split Hopkinson bar techniques. The data on 1080 steel exhibited a typical strain hardening response, whereas Vasco-Max 300 steel showed diminishing flow stress beyond yielding because of localized necking in gauge section of the tested specimens. The tension data are analyzed to determine the Johnson-Cook (J-C) strength model constants for the two steels. The flow stress values for VascoMax are adjusted to account for necking, and the corrected J-C model is developed

  5. On a Robust MaxEnt Process Regression Model with Sample-Selection

    Directory of Open Access Journals (Sweden)

    Hea-Jung Kim

    2018-04-01

    Full Text Available In a regression analysis, a sample-selection bias arises when a dependent variable is partially observed as a result of the sample selection. This study introduces a Maximum Entropy (MaxEnt process regression model that assumes a MaxEnt prior distribution for its nonparametric regression function and finds that the MaxEnt process regression model includes the well-known Gaussian process regression (GPR model as a special case. Then, this special MaxEnt process regression model, i.e., the GPR model, is generalized to obtain a robust sample-selection Gaussian process regression (RSGPR model that deals with non-normal data in the sample selection. Various properties of the RSGPR model are established, including the stochastic representation, distributional hierarchy, and magnitude of the sample-selection bias. These properties are used in the paper to develop a hierarchical Bayesian methodology to estimate the model. This involves a simple and computationally feasible Markov chain Monte Carlo algorithm that avoids analytical or numerical derivatives of the log-likelihood function of the model. The performance of the RSGPR model in terms of the sample-selection bias correction, robustness to non-normality, and prediction, is demonstrated through results in simulations that attest to its good finite-sample performance.

    The recovery of genomes from metagenomic datasets is a critical step to defining the functional roles of the underlying uncultivated populations. We previously developed MaxBin, an automated binning approach for high-throughput recovery of microbial genomes from metagenomes. Here, we present an expanded binning algorithm, MaxBin 2.0, which recovers genomes from co-assembly of a collection of metagenomic datasets. Tests on simulated datasets revealed that MaxBin 2.0 is highly accurate in recovering individual genomes, and the application of MaxBin 2.0 to several metagenomes from environmental samples demonstrated that it could achieve two complementary goals: recovering more bacterial genomes compared to binning a single sample as well as comparing the microbial community composition between different sampling environments.

    2014-01-01

    Corrosion resistant, strain tolerant MAX phase coatings are of interest for turbine applications. Thin Cr2AlC MAX phase wafers were vacuum diffusion bonded to an advanced turbine disk alloy, LSHR, at 1100 C. The interface, examined by optical and scanning electron microscopy, revealed a primary diffusion zone consisting of 10 micrometers of beta-Ni(Co)Al, decorated with various NiCoCrAl, MC and M3B2 precipitates. On the Cr2AlC side, an additional 40 micrometers Al-depletion zone of Cr7C3 formed in an interconnected network with the beta-Ni(Co)Al. Oxidation of an exposed edge at 800 C for 100 h produced a fine-grained lenticular alumina scale over Cr2AlC and beta-Ni(Co)Al, with coarser chromia granules over the Cr7C3 regions. Subsequent growth of the diffusion layers was only 5 micrometers in total. A residual stress of 500 MPa was estimated for the MAX phase layer, but no interfacial damage was observed. Subsequent tests for 1000 h reveal similar results.

  14. Fuzzy Mutual Information Based min-Redundancy and Max-Relevance Heterogeneous Feature Selection

    Directory of Open Access Journals (Sweden)

    Daren Yu

    2011-08-01

    Full Text Available Feature selection is an important preprocessing step in pattern classification and machine learning, and mutual information is widely used to measure relevance between features and decision. However, it is difficult to directly calculate relevance between continuous or fuzzy features using mutual information. In this paper we introduce the fuzzy information entropy and fuzzy mutual information for computing relevance between numerical or fuzzy features and decision. The relationship between fuzzy information entropy and differential entropy is also discussed. Moreover, we combine fuzzy mutual information with qmin-Redundancy-Max-Relevanceq, qMax-Dependencyq and min-Redundancy-Max-Dependencyq algorithms. The performance and stability of the proposed algorithms are tested on benchmark data sets. Experimental results show the proposed algorithms are effective and stable.

  15. Time limit and time at VO2max' during a continuous and an intermittent run.

    Demarie, S; Koralsztein, J P; Billat, V

    2000-06-01

    The purpose of this study was to verify, by track field tests, whether sub-elite runners (n=15) could (i) reach their VO2max while running at v50%delta, i.e. midway between the speed associated with lactate threshold (vLAT) and that associated with maximal aerobic power (vVO2max), and (ii) if an intermittent exercise provokes a maximal and/or supra maximal oxygen consumption longer than a continuous one. Within three days, subjects underwent a multistage incremental test during which their vVO2max and vLAT were determined; they then performed two additional testing sessions, where continuous and intermittent running exercises at v50%delta were performed up to exhaustion. Subject's gas exchange and heart rate were continuously recorded by means of a telemetric apparatus. Blood samples were taken from fingertip and analysed for blood lactate concentration. In the continuous and the intermittent tests peak VO2 exceeded VO2max values, as determined during the incremental test. However in the intermittent exercise, peak VO2, time to exhaustion and time at VO2max reached significantly higher values, while blood lactate accumulation showed significantly lower values than in the continuous one. The v50%delta is sufficient to stimulate VO2max in both intermittent and continuous running. The intermittent exercise results better than the continuous one in increasing maximal aerobic power, allowing longer time at VO2max and obtaining higher peak VO2 with lower lactate accumulation.

  17. Activity of flavonoids through λ sub max and electron cross-section

    International Nuclear Information System (INIS)

    Murthy, V.R.; Sreenivasulu, M.

    1997-01-01

    Flavonoids are widespread groups of natural constituents and present in the drugs in the form of mono or diglycosides. Being physiologically active, flavonoids are important in the field of pharmacological and clinical applications. Not many physical properties of flavonoids have been studied so far excepting UV and NMR studies. This paper deals with the evaluation of electron ionization cross section through λ sub max, a parameter available from UV studies. Electron ionization cross section was primarily conceived to be of use in radiation chemical data, mass spectroscopic and thermodynamic studies. But later attempts to correlate electron ionization cross-section with structural and related parameters prompted the authors to derive an explicit expression relating λ sub max and electron ionization cross-section (Q). The application of this method to correlate Q through λ sub max and interpret the results in terms of chemical activity are discussed

    Full Text Available Abstract Background To prevent early exit from work, it is important to study which factors contribute to healthy ageing. One concept that is assumed to be closely related to, and therefore may influence healthy ageing, is vitality. Vitality consists of both a mental and a physical component, and is characterised by a perceived high energy level, decreased feelings of fatigue, and feeling fit. Since VO2max gives an indication of one's aerobic fitness, which can be improved by increased levels of physical activity, and because feeling fit is one of the main characteristics of vitality, it is hypothesised that VO2max is related to vitality. Therefore, the aim of this study was to investigate the associations between VO2max and vitality. Methods In 427 older workers (aged 45 + years participating in the Vital@Work study, VO2max was estimated at baseline using the 2-km UKK walk test. Vitality was measured by both the UWES Vitality Scale and the RAND-36 Vitality Scale. Associations were analysed using linear regression analyses. Results The linear regression models, adjusted for age, showed a significant association between VO2max and vitality measured with the RAND-36 Vitality Scale (β = 0.446; 95% CI: 0.220-0.673. There was no significant association between VO2max and vitality measured with the UWES (β = -0.006; 95% CI:-0.017 - 0.006, after adjusting for age, gender and chronic disease status. Conclusions VO2max was associated with a general measure of vitality (measured with the RAND-36 Vitality Scale, but not with occupational health related vitality (measured with the UWES Vitality Scale. The idea that physical exercise can be used as an effective tool for improving vitality was supported in this study. Trial registration NTR1240

    In recent years, ground-based multi-axis differential absorption spectroscopy (MAX-DOAS) has shown to be ideally suited for the retrieval of tropospheric trace gases and deriving information on the aerosol properties. These measurements are invaluable to our understanding of the physics and chemistry of the atmospheric system, and the impact on the Earth's climate. Unfortunately, MAX-DOAS measurements are often performed under (partially) cloudy conditions, causing data quality degradation and higher uncertainties on the retrievals. A high aerosol load and/or a strong cloud cover can introduce additional photon absorption or multiple scattering. The first effect strongly impacts the retrieved differential slant columns (DSCDs) of the trace gases, leading to an underestimation of the atmospheric column density. Multiple scattering, on the other hand, becomes important for low clouds with a high optical depth, and cause a strong increase in the retrieved trace gas DSCDs. The presence of thin clouds can furthermore introduce a degeneracy in the retrieved aerosol optical depth, since they will have similar effect on the MAX-DOAS measurements. In this case, only information on the trace gas DSCDs can be successfully retrieved. If the cloud cover consists of broken or scattered clouds, the MAX-DOAS method becomes very unstable, since the different elevation angels will probe regions of the sky with strongly deviating properties. Here we present a method to qualify the sky and cloud conditions, using the colour index and O4 DSCDs, as derived from the MAX-DOAS measurements. The colour index is defined as the ratio of the intensities at the short- and long-wavelength part of the visible spectral range, typically at 400 nm and 670 nm. For increasing optical thickness due to clouds or aerosols, the colour index values decrease and values for different elevation angles converge. In the case of broken clouds, the colour index shows a strong and rapid temporal variation, which

    IEEE specifies different modulation techniques for WiMAX; namely, BPSK, QPSK, 16 QAM and 64 QAM. This paper studies the performance of Internet Protocol Television (IPTV) over Fixed WiMAX system considering different combinations of digital modulation. The performance is studied taking into account a number of key system parameters which include the variation in the video coding, path-loss, scheduling service classes different rated codes in FEC channel coding. The performance study was conducted using OPNET simulation. The performance is studied in terms of packet lost, packet jitter delay, end-to-end delay, and network throughput. Simulation results show that higher order modulation and coding schemes (namely, 16 QAM and 64 QAM) yield better performance than that of QPSK.

    Max-trees, or component trees, are graph structures that represent the connected components of an image in a hierarchical way. Nowadays, many application fields rely on images with high-dynamic range or floating point values. Efficient sequential algorithms exist to build trees and compute attributes for images of any bit depth. However, we show that the current parallel algorithms perform poorly already with integers at bit depths higher than 16 bits per pixel. We propose a parallel method combining the two worlds of flooding and merging max-tree algorithms. First, a pilot max-tree of a quantized version of the image is built in parallel using a flooding method. Later, this structure is used in a parallel leaf-to-root approach to compute efficiently the final max-tree and to drive the merging of the sub-trees computed by the threads. We present an analysis of the performance both on simulated and actual 2D images and 3D volumes. Execution times are about better than the fastest sequential algorithm and speed-up goes up to on 64 threads.

We examined the association between negative early life events and social anxiety in a sample of 571 Spanish University students. METHODS: In a cross-sectional survey conducted in 2007, we collected data through a semistructured questionnaire of sociodemographic variables, personal and family psychiatric history, and substance abuse. We assessed the five early negative life events: (i the loss of someone close, (ii emotional abuse, (iii physical abuse, (iv family violence, and (v sexual abuse. All participants completed the Liebowitz Social Anxiety Scale. RESULTS: Mean (SD age was 21 (4.5, 75% female, LSAS score was 40 (DP = 22, 14.2% had a psychiatric family history and 50.6% had negative life events during childhood. Linear regression analyses, after controlling for age, gender, and family psychiatric history, showed a positive association between family violence and social score (p = 0.03. None of the remaining stressors produced a significant increase in LSAS score (p > 0.05. CONCLUSION: University students with high levels of social anxiety presented higher prevalence of negative early life events.

    Orthogonal frequency division multiplexing (OFDM) has been used in many wireless communication systems also it is gaining a lot of attention for the next generations of mobile communication systems. OFDM is considered a good candidate for wireless systems because it has high bandwidth efficiency and can transmit at very high data rate in multi path, interference , and fading environment. in general OFDM has widely been studied and implemented to combat transmission channel impairments, but some challenges still facing OFDM in transmission system implementation especially for recent and future applications. One of these important applications is the worldwide interoperability for microwave access (WiMAX) system. According to the IEEE 802.16 standards, WiMAX is considered as a good solution for last mile connection at crowded areas and a high-speed internet connection to mobile vehicles with speed of up to 300 km/h. This thesis studies OFDM system in details and proposes simulink models for simulating OFDM impairments and its effects on system performance. This study has been used for building up system level and end to end WiMAX OFDM transmitter/receiver which follows published specifications in IEEE 802.16 standards using mat lab/simulink.

    The aim of this study was to test the hypothesis that individual differences in the response of maximal O(2) uptake (VO(2max)) to a standardized training program are characterized by familial aggregation. A total of 481 sedentary adult Caucasians from 98 two-generation families was exercise trained for 20 wk and was tested for VO(2max) on a cycle ergometer twice before and twice after the training program. The mean increase in VO(2max) reached approximately 400 ml/min, but there was considerable heterogeneity in responsiveness, with some individuals experiencing little or no gain, whereas others gained >1.0 l/min. An ANOVA revealed that there was 2.5 times more variance between families than within families in the VO(2max) response variance. With the use of a model-fitting procedure, the most parsimonious models yielded a maximal heritability estimate of 47% for the VO(2max) response, which was adjusted for age and sex with a maternal transmission of 28% in one of the models. We conclude that the trainability of VO(2max) is highly familial and includes a significant genetic component.

    Recently derestricted Freud Archive interviews with Max and Herbert Graf and Herbert's wife shed new light on Max Graf's article, "Reminiscences of Professor Sigmund Freud," published in The Psychoanalytic Quarterly in 1942. To explain discrepancies between the interviews and the earlier article, the author postulates that, in the article, Max Graf purposely distorted or omitted certain details in order not to reveal Herbert's identity as "Little Hans" (Freud 1909). The interviews place incidents reported in the article in a new and more complex light, and also underscore the intensely personal nature of the intellectual development of the psychoanalytic movement.

    Full Text Available La investigación tuvo como propósito comprender la agresión comunicativa entre estudiantes de cuarto grado de primaria. Nos enfocamos en el análisis de la agresión como un tipo de evento comunicativo que se desarrolla a través de normas de interacción e interpretación lingüística -verbales y no verbales- aprendidas y desarrolladas en comunidades de habla específicas. A través de un ejercicio extenso de etnografía de aula realizamos un análisis de actos comunicativos entre los escolares, especialmente durante los juegos. Analizamos las normas de interacción e interpretación puestas en escena durante eventos comunicativos escolares y lúdicos, para conocer los procesos de articulación de los enunciados interpretados como agresivos por los niños y las niñas. Los resultados señalan que en la dimensión comunicativa del juego escolar pueden surgir agresiones debido al manejo que los participantes hacen de las reglas y las normas comunicativas desarrolladas en el entorno cultural en el cual crecen e interactúan. El conjunto de competencias comunicativas aprendidas suele ser aprovechado para legitimar actos e interacciones agresivas de manera implícita, e incluirlo como parte de su cotidianidad escolar.

  4. The Max b-HLH-LZ can transduce into cells and inhibit c-Myc transcriptional activities.

    Directory of Open Access Journals (Sweden)

    Martin Montagne

    Full Text Available The inhibition of the functions of c-Myc (endogenous and oncogenic was recently shown to provide a spectacular therapeutic index in cancer mouse models, with complete tumor regression and minimal side-effects in normal tissues. This was achieved by the systemic and conditional expression of omomyc, the cDNA of a designed mutant of the b-HLH-LZ of c-Myc named Omomyc. The overall mode of action of Omomyc consists in the sequestration of Max and the concomitant competition of the Omomyc/Max complex with the endogenous c-Myc/Max heterodimer. This leads to the inhibition of the transactivation of Myc target genes involved in proliferation and metabolism. While this body of work has provided extraordinary insights to guide the future development of new cancer therapies that target c-Myc, Omomyc itself is not a therapeutic agent. In this context, we sought to exploit the use of a b-HLH-LZ to inhibit c-Myc in a cancer cell line in a more direct fashion. We demonstrate that the b-HLH-LZ domain of Max (Max* behaves as a bona fide protein transduction domain (PTD that can efficiently transduce across cellular membrane via through endocytosis and translocate to the nucleus. In addition, we show that the treatment of HeLa cells with Max* leads to a reduction of metabolism and proliferation rate. Accordingly, we observe a decrease of the population of HeLa cells in S phase, an accumulation in G1/G0 and the induction of apoptosis. In agreement with these phenotypic changes, we show by q-RT-PCR that the treatment of HeLa cells with Max* leads to the activation of the transcription c-Myc repressed genes as well as the repression of the expression of c-Myc activated genes. In addition to the novel discovery that the Max b-HLH-LZ is a PTD, our findings open up new avenues and strategies for the direct inhibition of c-Myc with b-HLH-LZ analogs.

  12. Tapered composite likelihood for spatial max-stable models

    KAUST Repository

    Sang, Huiyan

    2014-05-01

    Spatial extreme value analysis is useful to environmental studies, in which extreme value phenomena are of interest and meaningful spatial patterns can be discerned. Max-stable process models are able to describe such phenomena. This class of models is asymptotically justified to characterize the spatial dependence among extremes. However, likelihood inference is challenging for such models because their corresponding joint likelihood is unavailable and only bivariate or trivariate distributions are known. In this paper, we propose a tapered composite likelihood approach by utilizing lower dimensional marginal likelihoods for inference on parameters of various max-stable process models. We consider a weighting strategy based on a "taper range" to exclude distant pairs or triples. The "optimal taper range" is selected to maximize various measures of the Godambe information associated with the tapered composite likelihood function. This method substantially reduces the computational cost and improves the efficiency over equally weighted composite likelihood estimators. We illustrate its utility with simulation experiments and an analysis of rainfall data in Switzerland.

  13. Effective Bandwidth Allocation for WiMAX Mesh Network

    Directory of Open Access Journals (Sweden)

    Hung-Chin Jang

    2010-04-01

    Full Text Available The aim of this paper is to reduce the media access delay in a WiMAX mesh network. We observe that as the number of subscriber stations (SS in a neighborhood increases, the processes of transmission opportunity (TO competition and 3- way handshake are easy to fail. This may degrade transmission efficiency and increase packet transmission delay. Besides, the minislot allocation defined in the WiMAX mesh mode may cause many lower priority services reserve earlier minislots than that of higher priority services like rtPS. This may cause great negative impact on delay-sensitive traffic. In this paper, we design a QoS classifier to enqueue packets according to different QoS service classes, present a dynamic holdoff exponent mechanism to reduce control subframe delay, and propose a Neighborhood-Based Minislot Allocation (NBMA mechanism to reduce data subframe delay. Simulations show that the proposed methodology outperforms that of IEEE 802.16 and Baye's DynExp in delay, jitter and throughput.

  14. Tapered composite likelihood for spatial max-stable models

    Spatial extreme value analysis is useful to environmental studies, in which extreme value phenomena are of interest and meaningful spatial patterns can be discerned. Max-stable process models are able to describe such phenomena. This class of models is asymptotically justified to characterize the spatial dependence among extremes. However, likelihood inference is challenging for such models because their corresponding joint likelihood is unavailable and only bivariate or trivariate distributions are known. In this paper, we propose a tapered composite likelihood approach by utilizing lower dimensional marginal likelihoods for inference on parameters of various max-stable process models. We consider a weighting strategy based on a "taper range" to exclude distant pairs or triples. The "optimal taper range" is selected to maximize various measures of the Godambe information associated with the tapered composite likelihood function. This method substantially reduces the computational cost and improves the efficiency over equally weighted composite likelihood estimators. We illustrate its utility with simulation experiments and an analysis of rainfall data in Switzerland.

  17. On the Potential of MAX phases for Nuclear Applications

    Science.gov (United States)

    Tallman, Darin Joseph

    Materials within nuclear reactors experience some of the harshest environments currently known to man, including long term operation in extreme temperatures, corrosive media, and fast neutron fluences with up to 100 displacements per atom, dpa. In order to improve the efficiency and safety of current and future reactors, new materials are required to meet these harsh demands. The M n+1AXn phases, a growing family of ternary nano-layered ceramics, possess a desirable combination of metallic and ceramic properties. They are composed of an early transition metal (M), a group 13--16 element (A), and carbon and/or nitrogen (X). The MAX phases are being proposed for use in such extreme environments because of their unique combination of high fracture toughness values and thermal conductivities, machinability, oxidation resistance, and ion irradiation damage tolerance. Previous ion irradiation studies have shown that Ti3SiC2 and Ti3AlC2 resist irradiation damage, maintaining crystallinity up to 50 dpa. The aim of this work was to explore the effect of neutron irradiation, up to 9 dpa and at temperatures of 100 to 1000 °C, on select MAX phases for the first time. The MAX phases Ti3SiC2, Ti 3AlC2, Ti2AlC, and Ti2AlN were synthesized, and irradiated in test reactors that simulate in-pile conditions of nuclear reactors. X-ray diffraction, XRD, pattern refinements of samples revealed a distortion of the crystal lattice after low temperature irradiation, which was not observed after high temperature irradiations. Additionally, the XRD results indicated that Ti3AlC2 and Ti2AlN dissociated after relatively low neutron doses. This led us to focus on Ti 3SiC2 and Ti2AlC. For the first time, dislocation loops were observed in Ti3SiC 2 and Ti2AlC as a result of neutron irradiation. At 1 x 1023 loops/m3, the loop density in Ti2 AlC after irradiation to 0.1 dpa at 700°C was 1.5 orders of magnitude greater than that observed in Ti3SiC2, at 3 x 1021 loops/m3.

    Increases in maximal oxygen uptake (V˙O2max) frequently occur with high-intensity interval training (HIIT), yet the specific adaptation explaining this result remains elusive. This study examined changes in V˙O2max and cardiac output (CO) in response to periodized HIIT. Thirty-nine active men and women (mean age and V˙O2max = 22.9 ± 5.4 yr and 39.6 ± 5.6 mL·kg·min) performed HIIT and 32 men and women (age and V˙O2max = 25.7 ± 4.5 yr and 40.7 ± 5.2 mL·kg·min) were nonexercising controls (CON). The first 10 sessions of HIIT required eight to ten 60 s bouts of cycling at 90%-110% percent peak power output interspersed with 75 s recovery, followed by randomization to one of three regimes (sprint interval training (SIT), high-volume interval training (HIITHI), or periodized interval training (PER) for the subsequent 10 sessions. Before, midway, and at the end of training, progressive cycling to exhaustion was completed during which V˙O2max and maximal CO were estimated. Compared with CON, significant (P HIIT + SIT (39.8 ± 7.3 mL·kg·min to 43.6 ± 6.1 mL·kg·min), HIIT + HIITHI (41.1 ± 4.9 mL·kg·min to 44.6 ± 7.0 mL·kg·min), and HIIT + PER (39.5 ± 5.6 mL·kg·min to 44.1 ± 5.4 mL·kg·min) occurred which were mediated by significant increases in maximal CO (20.0 ± 3.1 L·min to 21.7 ± 3.2 L·min, P = 0.04). Maximal stroke volume was increased with HIIT (P = 0.04), although there was no change in maximal HR (P = 0.88) or arteriovenous O2 difference (P = 0.36). These CO data are accurate and represent the mean changes from pre- to post-HIIT across all three training groups. Increases in V˙O2max exhibited in response to different HIIT regimes are due to improvements in oxygen delivery.

The t95%VO2max was significantly higher at 110%vVO2max (EI110% (218.1 ± 81.6s compared to 100% vVO2max (EI100% (91.9 ± 75.2s and 120%vVO2max (EI120% (126.3 ± 29.4s, but without differences between EI100% and EI120%. The t90%vVO2max was significantly different only between EI110% and 120%. Therefore, we conclude that during intermittent exercise with ratio 30s:15s, the intensity of 110%vVO2max appears more appropriate to maintain VO2max for a longer time.

    Field experiment was conducted at Agricultural and Natural Resources Research Center of Golestan Province, Iran, to determine the effects of tillage system and weed management regime on yield and weed populations in soybean ( Glycin max L.). The experimental design was a split plot where the whole plot portion was a randomized complete block with three replicates. Main plots were tillage system: 1- No-till row crop seeding, 2- No-till seed drilling, 3- Tillage with disc harrow and drill planting, 4- Tillage with chisel packer and drill planting. The subplots were weed management regimes: 1-Weed control with herbicide application, 2- Hand weeding, 3- Herbicide application plus hand weeding, and 4- Non-weeding. Results indicated that the main effects of tillage system and weed management regime were significant for seed yield, pod number per plant, seed number per pod, weed density and biomass, while their interaction were significant only for weed density, weed biomass, and seed number per pod. The highest grain yields (3838 kg ha-1) were recorded for No-till row crop seeding. The highest seed yield (3877 kg ha-1) also was recorded for weed control with herbicide and hand weeding treatment, followed by hand weeding (3379 kg ha-1).

    The purpose of this study was to measure, in swimming pool conditions and with high level swimmers, the time to exhaustion at the minimum velocity that elicits maximal oxygen consumption (TLim at vVO(2)max), and the corresponding VO(2) slow component (O(2)SC). The vVO(2)max was determined through an intermittent incremental test (n = 15). Forty-eight hours later, TLim was assessed using an all-out swim at vVO(2)max until exhaustion. VO(2) was measured through direct oximetry and the swimming velocity was controlled using a visual light-pacer. Blood lactate concentrations and heart rate values were also measured. Mean VO(2)max for the incremental test was 5.09 +/- 0.53 l/min and the corresponding vVO(2)max was 1.46 +/- 0.06 m/s. Mean TLim value was 260.20 +/- 60.73 s and it was inversely correlated with the velocity of anaerobic threshold (r = -0.54, p energy cost of the respiratory muscles (r = 0.51), for p swimming pool, in high level swimmers performing at vVO(2)max, and that higher TLim seems to correspond to higher expected O(2)SC amplitude. These findings seem to bring new data with application in middle distance swimming.

    Full Text Available O litoral do Rio de Janeiro foi atingido, nos últimos 15 anos, por duas tempestades excepcionais. A primeira em Maio de 2001 e a segunda em Abril de 2010. A primeira provocou erosão pronunciada na orla costeira voltada para o sul, isto é entre o Cabo Frio e a Marambaia, enquanto a segunda teve esse efeito no litoral leste do estado a norte do Cabo Frio devido à direção de incidência das ondas que em vez de sul sul-sudeste, mais comum, vieram de sudeste. No presente trabalho é apresentada uma análise do comportamento morfodinâmico da orla costeira a norte dos cabos Frio e Búzios, mais especificamente das praias do Peró, Tucuns, Barra de São João e Rio das Ostras (Abricó, antes e após a tempestade de abril de 2010 abrangendo períodos de até 17 anos em Barra de São João (1996 a 2013 a um mínimo de 7 anos (2007 a 2014 na praia do Peró. O clima de ondas de sudeste, para os últimos 30 anos (1981 a 2011, foi obtido por meio de reanálise dos ventos com filtragem posterior para ondas com altura superior a 3 m e 3,5 m consideradas, neste trabalho, como representativas de ressacas excepcionais. Os resultados mostram que esses eventos extremos correspondem efetivamente aos eventos erosivos encontrados, cuja ocorrência se dá numa frequência muito baixa, permitindo a recuperação do estoque de sedimentos da praia e da base das dunas frontais, com exceção da Praia do Abricó em Rio das Ostras, que apresenta uma tendência histórica de déficit no balanço sedimentar. Para o período do clima de ondas analisado não foi identificada uma tendência de aumento da recorrência, principalmente para ondas de altura superior a 3,5 m. A menor frequência de ocorrência de eventos extremos, quando comparado com outros segmentos, mais expostos, do litoral do Rio de Janeiro, se deve à proteção às ondas de sul e sul-sudoeste exercido pela orientação da linha de costa e da sombra exercida pelo Cabo Frio e Cabo Búzios.

  8. V/V/sub max/ test for QSOs: comments on the paper by Hawkins and Stewart

    Wills, D.

    1983-01-01

    Hawkins and Stewart's interpretation of the results of the V/V/sub max/ test for QSO samples is shown to be invalid. Their suggestion that the high values of V/V/sub max/ at small redshifts result from the exclusion of nearby QSOs from the samples is examined quantitatively for the well-studied 3CR sample, and shown to have a negligible effect on the results. Their claim that the values of V/V/sub max/ at larger redshifts indicate a uniform space density of QSOs is not true after an error in their calculations is corrected. Although the V/V/sub max/ test is less sensitive to space density evolution at large redshifts, current results are in good agreement with the hypothesis that a single density evolution law describes the observations out to a redshift of at least 2.5

    Full Text Available The irregularity of removing quantities from a definite picking location in a warehouse very often results in the stock out in the particular picking address. In practice, the Red Card principle is used to determine a critical level for each picking location when it is necessary to start the replenishment of stock in the picking address. The question is how to calculate an adequate critical level. The guidelines in this paper explain in detail the solution of the problem using the Min/Max stock control method and mathematical algorithms adjusted by authors. In order to check the validity of these mathematical algorithms of the Min/Max method, the simulation modelling has been also done and presented.

    2013-02-01

    The purpose of this study was to estimate the percentage of the increase in whole body maximal oxygen consumption (.VO(2max)) that is accounted for by increased respiratory muscle oxygen uptake after altitude training. Six elite male distance runners (.VO(2max) = 70.6 ± 4.5 ml kg(-1) min(-1)) and one elite female distance runner (.VO(2max)) = 64.7 ml kg(-1) min(-1)) completed a 28-day "live high-train low" training intervention (living elevation, 2,150 m). Before and after altitude training, subjects ran at three submaximal speeds, and during a separate session, performed a graded exercise test to exhaustion. A regression equation derived from published data was used to estimate respiratory muscle .VO(2) (.VO(2RM)) using our ventilation (.VE) values. .VO(2RM) was also estimated retrospectively from a larger group of distance runners (n = 22). .VO(2max) significantly (p altitude (196 ± 59 ml min(-1)), while (.VE) at .VO(2max) also significantly (p altitude (201 ± 36 ml min(-1)), along with a 10.8 ± 2.1 l min(-1) increase in (.VE), thus requiring an estimated 27 % of Δ .VO(2max) Our data suggest that a substantial portion of the improvement in .VO(2max) with chronic altitude training goes to fuel the respiratory muscles as opposed to the musculature which directly contributes to locomotion. Consequently, the time-course of decay in ventilatory acclimatization following return to sea-level may have an impact on competitive performance.

    2017-08-01

    Generalized canonical correlation analysis (GCCA) aims at finding latent low-dimensional common structure from multiple views (feature vectors in different domains) of the same entities. Unlike principal component analysis (PCA) that handles a single view, (G)CCA is able to integrate information from different feature spaces. Here we focus on MAX-VAR GCCA, a popular formulation which has recently gained renewed interest in multilingual processing and speech modeling. The classic MAX-VAR GCCA problem can be solved optimally via eigen-decomposition of a matrix that compounds the (whitened) correlation matrices of the views; but this solution has serious scalability issues, and is not directly amenable to incorporating pertinent structural constraints such as non-negativity and sparsity on the canonical components. We posit regularized MAX-VAR GCCA as a non-convex optimization problem and propose an alternating optimization (AO)-based algorithm to handle it. Our algorithm alternates between {\\em inexact} solutions of a regularized least squares subproblem and a manifold-constrained non-convex subproblem, thereby achieving substantial memory and computational savings. An important benefit of our design is that it can easily handle structure-promoting regularization. We show that the algorithm globally converges to a critical point at a sublinear rate, and approaches a global optimal solution at a linear rate when no regularization is considered. Judiciously designed simulations and large-scale word embedding tasks are employed to showcase the effectiveness of the proposed algorithm.

    Full Text Available This paper reports on the design of an OPNET simulation platform to test the performance of sending real-time safety video over VANET (Vehicular Adhoc NETwork using the WiMAX technology. To provide a more realistic environment for streaming real-time video, a video model was created based on the study of video traffic traces captured from a realistic vehicular camera, and different design considerations were taken into account. A practical controller over real-time streaming protocol is implemented to control data traffic congestion for future road safety development. Our driving video model was then integrated with the WiMAX OPNET model along with a mobility model based on real road maps. Using this simulation platform, different mobility cases have been studied and the performance evaluated in terms of end-to-end delay, jitter and visual experience.

    Full Text Available This research presents a rectangular ring antenna excited by a circular disc monopole (CDM mounted in front of a square reflector. The proposed antenna is designed to cover a frequency range of 2.300–5.825 GHz and thereby is suitable for WiMAX applications. Multiple parametric studies were carried out using the CST Microwave Studio simulation program. A prototype antenna was fabricated and experimented. The measurements were taken and compared with the simulation results, which indicates good agreement between both results. The prototype antenna produces an impedance bandwidth (|S11| < −10 dB that covers the WiMAX frequency range and a constant unidirectional radiation pattern (θ=0° and ∅=90°. The minimum and maximum gains are 3.7 and 8.7 dBi, respectively. The proposed antenna is of compact size and has good unidirectional radiation performance. Thus, it is very suitable for a multitude of WiMAX applications.

    Improving reliability has recently become a very important objective in the field of particle accelerators. The particle accelerators in operation are constantly undergoing modifications, and improvements are implemented using new technologies, more reliable components or redundant schemes (to obtain more reliability, strength, more power, etc.) A reliability model of SNS (Spallation Neutron Source) LINAC has been developed within MAX project and analysis of the accelerator systems reliability has been performed within the MAX project, using the Risk Spectrum reliability analysis software. The analysis results have been evaluated by comparison with the SNS operational data. Results and conclusions are presented in this paper, oriented to identify design weaknesses and provide recommendations for improving reliability of MYRRHA linear accelerator. The SNS reliability model developed for the MAX preliminary design phase indicates possible avenues for further investigation that could be needed to improve the reliability of the high-power accelerators, in view of the future reliability targets of ADS accelerators.

    Full Text Available The flexible manufacturing system (FMS executes multiple processes simultaneously using a limited set of resources. These processes can be blocked permanently due to the sequence of the activities, i.e., the processes sharing a finite set of resources may eventually lead to a deadlock state. The FMS belongs to the class of discrete event systems where it is not possible to determine when an event will occur and the sequence of events becomes undefined. Such systems can be modeled using Petri net, and this work presents a method that solves the deadlock problem considering the indeterminism of FMSs. The goal of this work is to introduce an algorithmic approach, which allows the implementation of a computer program based on FMS functional specification. The proposal is to automate the generation of the control strategy for resource utilization and the rules to avoid the deadlock situation.O sistema flexível de manufatura (FMS flexible manufacturing system executa múltiplos processos simultaneamente que utilizam um conjunto limitado de recursos. Estes processos podem ficar permanentemente bloqueados em função da seqüência de atividades, isto é, o compartilhamento de um conjunto finito de recursos pode levar o sistema a um estado de autotravamento. O FMS pode ser visto como pertencente a uma classe de sistema a eventos discretos, onde não é possível determinar quando um evento ocorre e com isto a seqüência de eventos fica indefinida. Este tipo de sistema pode ser modelado através de rede de Petri e assim explora-se esta técnica para desenvolver uma solução para o problema de auto-travamento considerando o indeterminismo do FMS. O objetivo é introduzir uma abordagem algorítmica para a implementação de uma ferramenta computacional baseada na especificação funcional do FMS e que automatize a geração de uma estratégia de controle para a utilização de recursos e de regras para evitar o autotravamento.

    In order to predict correctly the Ground Penetrating Radar (GPR) response from a particular scenario, Maxwell's equations have to be solved, subject to the physical and geometrical properties of the considered problem and to its initial conditions. Several techniques have been developed in computational electromagnetics, for the solution of Maxwell's equations. These methods can be classified into two main categories: differential and integral equation solvers, which can be implemented in the time or spectral domain. All of the different methods present compromises between computational efficiency, stability, and the ability to model complex geometries. The Finite-Difference Time-Domain (FDTD) technique has several advantages over alternative approaches: it has inherent simplicity, efficiency and conditional stability; it is suitable to treat impulsive behavior of the electromagnetic field and can provide either ultra-wideband temporal waveforms or the sinusoidal steady-state response at any frequency within the excitation spectrum; it is accurate and highly versatile; and it has become a mature and well-researched technique. Moreover, the FDTD technique is suitable to be executed on parallel-processing CPU-based computers and to exploit the modern computer visualisation capabilities. GprMax [1] is a very well-known and largely validated FDTD software tool, implemented by A. Giannopoulos and available for free public download on www.gprmax.com, together with examples and a detailled user guide. The tool includes two electromagnetic wave simulators, GprMax2D and GprMax3D, for the full-wave simulation of two-dimensional and three-dimensional GPR models. In GprMax, everything can be done with the aid of simple commands that are used to define the model parameters and results to be calculated. These commands need to be entered in a simple ASCII text file. GprMax output files can be stored in ASCII or binary format. The software is provided with MATLAB functions, which

The quality of an IPTV service definitely depends on the allocated bandwidth for that channel. However, due to the high quality IPTV services and to support of huge non-IPTV traffic over mobile WiMAX networks, it is not possible to guarantee the sufficient ...

    The next generation of instrumentation for nuclear astrophysics will have to achieve an improvement in sensitivity by a factor of 10-100 over present technologies. With the focusing gamma-ray telescope MAX we take up this challenge and propose to combine the required sensitivity with high spectral and angular resolution, and the capability to measure the polarization of the photons. MAX is a space-borne crystal diffraction telescope, featuring a broad-band Laue lens optimized for the observation of compact sources in two wide energy bands of high astrophysical relevance. Gamma rays will be focused from the large collecting area of a crystal diffraction lens onto a very small detector volume. As a consequence, the signal to background ratio is greatly enhanced, leading to unprecedented sensitivities

  7. Spanish genetic admixture is associated with larger V(O2) max decrement from sea level to 4338 m in Peruvian Quechua.

    Quechua in the Andes may be genetically adapted to altitude and able to resist decrements in maximal O2 consumption in hypoxia (DeltaVo2 max). This hypothesis was tested via repeated measures of Vo2 max (sea level vs. 4338 m) in 30 men of mixed Spanish and Quechua origins. Individual genetic admixture level (%Spanish ancestry) was estimated by using ancestry-informative DNA markers. Genetic admixture explained a significant proportion of the variability in DeltaVo2 max after control for covariate effects, including sea level Vo2 max and the decrement in arterial O2 saturation measured at Vo2 max (DeltaSpO2 max) (R2 for admixture and covariate effects approximately 0.80). The genetic effect reflected a main effect of admixture on DeltaVo2 max (P = 0.041) and an interaction between admixture and DeltaSpO2 max (P = 0.018). Admixture predicted DeltaVo2 max only in subjects with a large DeltaSpO2 max (P = 0.031). In such subjects, DeltaVo2 max was 12-18% larger in a subgroup of subjects with high vs. low Spanish ancestry, with least squares mean values (+/-SE) of 739 +/- 71 vs. 606 +/- 68 ml/min, respectively. A trend for interaction (P = 0.095) was also noted between admixture and the decrease in ventilatory threshold at 4338 m. As previously, admixture predicted DeltaVo2 max only in subjects with a large decrease in ventilatory threshold. These findings suggest that the genetic effect on DeltaVo2 max depends on a subject's aerobic fitness. Genetic effects may be more important (or easier to detect) in athletic subjects who are more likely to show gas-exchange impairment during exercise. The results of this study are consistent with the evolutionary hypothesis and point to a better gas-exchange system in Quechua.

  10. Cosmological Constraints From SDSS MaxBCG Cluster Abundances

    Rozo, Eduardo; Wechsler, Risa H.; KICP, Chicago; Koester, Benjamin P.; McKay, Timothy A.; Evrard, August E.; Johnston, David; Sheldon, Erin S.; Annis, James; Frieman, Joshua A.

    2007-01-01

    We perform a maximum likelihood analysis of the cluster abundance measured in the SDSS using the maxBCG cluster finding algorithm. Our analysis is aimed at constraining the power spectrum normalization σ 8 , and assumes flat cosmologies with a scale invariant spectrum, massless neutrinos, and CMB and supernova priors (Omega) m h 2 = 0.128 ± 0.01 and h = 0.72 ± 0.05 respectively. Following the method described in the companion paper Rozo et al. (2007), we derive σ 8 = 0.92 ± 0.10 (1σ) after marginalizing over all major systematic uncertainties. We place strong lower limits on the normalization, σ 8 > 0.76 (95% CL) (> 0.68 at 99% CL). We also find that our analysis favors relatively low values for the slope of the Halo Occupation Distribution (HOD), α = 0.83 ± 0.06. The uncertainties of these determinations will substantially improve upon completion of an ongoing campaign to estimate dynamical, weak lensing, and X-ray cluster masses in the SDSS maxBCG cluster sample

    2016-03-04

    Mass spectrometry-based proteomics coupled to liquid chromatography has matured into an automatized, high-throughput technology, producing data on the scale of multiple gigabytes per instrument per day. Consequently, an automated quality control (QC) and quality analysis (QA) capable of detecting measurement bias, verifying consistency, and avoiding propagation of error is paramount for instrument operators and scientists in charge of downstream analysis. We have developed an R-based QC pipeline called Proteomics Quality Control (PTXQC) for bottom-up LC-MS data generated by the MaxQuant software pipeline. PTXQC creates a QC report containing a comprehensive and powerful set of QC metrics, augmented with automated scoring functions. The automated scores are collated to create an overview heatmap at the beginning of the report, giving valuable guidance also to nonspecialists. Our software supports a wide range of experimental designs, including stable isotope labeling by amino acids in cell culture (SILAC), tandem mass tags (TMT), and label-free data. Furthermore, we introduce new metrics to score MaxQuant's Match-between-runs (MBR) functionality by which peptide identifications can be transferred across Raw files based on accurate retention time and m/z. Last but not least, PTXQC is easy to install and use and represents the first QC software capable of processing MaxQuant result tables. PTXQC is freely available at https://github.com/cbielow/PTXQC .

Este trabalho discute os usos do conceito de eventos privados a partir de questões levantadas pelo pragmatismo, filosofia com a qual aquele critério de verdade tem sido consistentemente identificado. É examinado em particular o enfoque relacional verbal na análise de conceitos relativos à privacidade, e como esse enfoque se reflete em uma rejeição do mentalismo e do organicismo. O trabalho segue discutindo a importância da comunidade verbal na produção do "mundo privado" individual. Por fim, ressalta-se que alguns autores afastam-se de uma referência funcional/instrumental ao elaborarem o problema da imprecisão de auto-descrições de eventos privados.The concept of private events has been used in behavior-analytic literature as a major topic to the treatment phenomena related to subjectivity, in the context of adopting instrumentality as a criterion of truth. This paper aims to discuss uses of the concept of private events from the standpoint of Pragmatism, a philosophy in which that criterion of truth has been consistently identified. It is particularly examined the focus on verbal relations in the analysis of contents related to privacy, and also how that focus reflects a rejection on mentalism and organicism. The paper continues to discuss the importance of the verbal community in the production of an individual "inside world".

    Childhood neuroblastoma, a disease of the sympathetic nervous system, is the most common solid tumour of infancy, remarkably refractory to therapeutic treatments. One of the most powerful independent prognostic indicators for this disease is the amplification of the MYCN oncogene, which occurs at high levels in approximately 25% of neuroblastomas. Interestingly, amplification and not just expression of MYCN has a strong prognostic value, although this fact appears quite surprising as MYCN is a transcription factor that requires dimerising with its partner MAX, to exert its function. This observation greatly suggests that the role of MYCN in neuroblastoma should be examined in the context of MAX expression. In this report, we show that, in contrast to what is found in normal cells, MAX expression is significantly different among primary NBs, and that its level appears to correlate with the clinical outcome of the disease. Importantly, controlled modulation of MAX expression in neuroblastoma cells with different extents of MYCN amplification, demonstrates that MAX can instruct gene transcription programs that either reinforce or weaken the oncogenic process enacted by MYCN. In general, our work illustrates that it is the MAX to MYCN ratio that can account for tumour progression and clinical outcome in neuroblastoma and proposes that such a ratio should be considered as an important criterion to the design and development of anti-MYCN therapies.

    2015-01-01

    Max-stable processes allow the spatial dependence of extremes to be modelled and quantified, so they are widely adopted in applications. For a better understanding of extremes, it may be useful to study several variables simultaneously. To this end, we study the maxima of independent replicates of multivariate processes, both in the Gaussian and Student-t cases. We define a Poisson process construction and introduce multivariate versions of the Smith Gaussian extreme-value, the Schlather extremal-Gaussian and extremal-t, and the Brown–Resnick models. We develop inference for the models based on composite likelihoods. We present results of Monte Carlo simulations and an application to daily maximum wind speed and wind gust.

    Peripheral intravenous catheter (PIV) insertion is a common, painful experience for many children in the pediatric emergency department. Although local anesthetics such as injected buffered lidocaine have been shown to be effective at reducing pain and anxiety associated with PIV insertion, they are not routinely used. ELA-Max, a topical local anesthetic, has the advantage of needle-free administration but has not been compared with buffered lidocaine for PIV insertion. To compare the reduction of pain and anxiety during PIV insertion provided by subcutaneous buffered 1% lidocaine or topical ELA-Max in children. A randomized trial in children 4 to 17 years old undergoing PIV insertion with 22-gauge catheters was conducted. Children received either buffered lidocaine or ELA-Max. Buffered lidocaine was administered by using 30-gauge needles to inject 0.1 to 0.2 mL subcutaneously just before PIV insertion. ELA-Max was applied to the skin and occluded with Tegaderm 30 minutes before PIV insertion. Self-reported Visual Analog Scale (VAS) questionnaires (rating on a scale of 1-10; 1 = no pain, anxiety) were completed by patients and their parents before PIV insertion to assess baseline perceptions about pain and anxiety associated with PIV insertion and immediately after PIV insertion to assess pain and anxiety associated with the experience. After PIV insertion, the nurse who inserted the PIV also completed a VAS questionnaire assessing technical difficulty and satisfaction with the local anesthesia. A blinded observer also completed a VAS questionnaire to assess pain and anxiety associated with the PIV insertion. Data were analyzed by using chi2 and t tests. Sixty-nine subjects were enrolled, and questionnaires were competed by all (mean age: 12.1 +/- 4.5 years; 61% female). There were no differences for buffered lidocaine and ELA-Max groups in age, gender, race, prior IV experience, or baseline pain and anxiety. There were no significant differences between buffered

    Full Text Available We present a simple analytical method for capacity evaluation of IEEE 802.16e Mobile WiMAX networks. Various overheads that impact the capacity are explained and methods to reduce these overheads are also presented. The advantage of a simple model is that the effect of each decision and sensitivity to various parameters can be seen easily. We illustrate the model by estimating the capacity for three sample applications—Mobile TV, VoIP, and data. The analysis process helps explain various features of IEEE 802.16e Mobile WiMAX. It is shown that proper use of overhead reducing mechanisms and proper scheduling can make an order of magnitude difference in performance. This capacity evaluation method can also be used for validation of simulation models.

    One of the supporting factors to have good aerobic endurance requires high VO2 max levels supported by good quality and quantity level of Haematology parameter especially such as erythrocytes, hematocrit and hemoglobin. One of the components in hemoglobin is iron which functions as theoxygen transport to parts of all body required in the process of metabolism. The objective of this research was to find out the difference between VO2 Max and Haematology parameter between iron supplying and no iron supplyingonmenstrual woman. The type of this research is quasi experimental research with non-randomized control group Pretest-Postest Design. The subjectsarethe studentsat faculty of Sports Sciences, Medan State University with the criteria of female gender, monthly regular menstrual cycle, having the level of health and the level of training, willing to be a sample by filling out informed consent. The total number of research subjectsis twenty students, divided into two groups namely the treatment group and the control group. The hematology parameter was measuredby Haemotology analyzer and VO2 Max was measured by multi-stage run. The result showed that there was a significant effect of iron supplyingon the increase of erythrocyte level on menstrual women, hemotocrit, haemoglobin and an increase in VO2 Max. Iron supplying on menstrual woman has the effect on the increase of erythrocyte, hematocrit, hemoglobin level and VO2 Max

  16. Structural and dynamic studies of the dimerization and DNA-binding domains of the transcription factors v-Myc and Max

    Fieber, W.

    2001-05-01

    In the present work, solution structural and dynamic properties of the dimerization and DNA binding domains of the transcription factors v-Myc and Max were characterized by NMR and CD spectroscopy. It could be demonstrated that v-Myc in the absence of its authentic binding partner Max does not homodimerize, but exists in a monomeric and prestructured form. Two separated α-helical regions in the leucine zipper region and in the basic-H1 region, respectively, could be identified, while the latter appeared to be less stable. Both helices lack stabilizing tertiary side chain interactions and represent exceptional examples for loosely coupled, structured segments in a native protein. The structure of v-Myc is dynamic and can be described as a distribution of conformational substates. Motion within the substates comprise fast (picosecond to nanosecond) local backbone fluctuations like helical fraying, whereas motion between the substates comprise the relative orientation of the two helices and occur at larger time scales (microsecond to millisecond). The preformation of the specific protein and DNA binding sites, leucine zipper and the basic region, presumably allows rapid and accurate recognition of the respective binding partners. v-Myc-Max and Max-Max protein preparations were shown to form stable dimers. Thermodynamic analysis of the dissociation reactions of v-Myc-Max revealed a significant higher stability of the heterodimer than of the Max-Max homodimer over the whole temperature range. It could be demonstrated that the restricted conformational space of the v-Myc bHLHZip domain reduces the entropy penalty associated with dimerization and contributes to the preference of Max to form heterodimers with v-Myc rather than homodimers.

    Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimator, and test its performance using the maxBCG cluster catalog. Our new estimator significantly reduces the variance in the L X -richness relation, from σ lnLx 2 = (0.86±0.02) 2 to σ lnLx 2 = (0.69±0.02) 2 . Relative to the maxBCG richness estimate, it also removes the strong redshift dependence of the L X -richness scaling relations, and is significantly more robust to photometric and redshift errors. These improvements are largely due to the better treatment of galaxy color data. We also demonstrate the scatter in the L X -richness relation depends on the aperture used to estimate cluster richness, and introduce a novel approach for optimizing said aperture which can easily be generalized to other mass tracers.

    The Max protein is the central dimerization partner in the Myc-Max-Mad network of transcriptional regulators, and a founding structural member of the family of basic-helix-loop-helix (bHLH)-leucine zipper (Zip) proteins. Biologically important regions flanking its bHLH-Zip motif have been disordered or absent in crystal structures. The present study shows that these regions are resistant to proteolysis in both the presence and absence of DNA, and that Max dimers containing both flanking regions have significantly higher helix content as measured by circular dichroism than that predicted from the crystal structures. Nuclear magnetic resonance measurements in the absence of DNA also support the inferred structural order. Deletion of both flanking regions is required to achieve maximal DNA affinity as measured by EMSA. Thus, the previously observed functionalities of these Max regions in DNA binding, phosphorylation, and apoptosis are suggested to be linked to structural properties

  2. Max Weber entre liberalismo y republicanismo

    Villacañas Berlanga, José Luis

    2005-12-01

    Full Text Available This article attempts to analyze the differences between social democracy and political democracy as modern processes, as these were understood by Max Weber. The archetype of modernity resides, from this point of view, in a convergence of both processes, as occurred in countries like the USA and Great Britain. Weber's diagnosis is that, whereas social democracy can be organized around liberal arguments, political democracy cannot advance without republican concepts like those of virtue, rigour, responsability and representation. For Weber, these values could only become present in Germany thanks to an adequate and democratic reception of Nietzsche, and in some way this reception could make sense of the former's work.

    Este artículo pretende analizar las diferencias entre democracia social y democracia política como procesos modernos, tal y como fueron comprendidos por Max Weber. Lo arquetípico de la modernidad reside, desde este punto de vista, en una convergencia de ambos procesos, tal y como se dio en países como USA y Gran Bretaña. El diagnóstico de Weber es que, mientras la democracia social puede organizarse sobre argumentos liberales, la democracia política no puede avanzar sin conceptos republicanos como el de virtud, rigor, responsabilidad y representación. Para Weber, estos valores sólo podrían hacerse presentes en Alemania a partir de una recepción adecuada y democrática de Nietzsche y en cierto modo esta recepción daría sentido a su obra.

    Full Text Available Il contributo indaga i limiti delle politiche urbane e in particolare di quelle sulla mobilità attuate per i Grandi Eventi, evidenziando in molti casi la tendenza a privilegiare la realizzazione di infrastrutture, più che politiche sui servizi, la cui reale utilità è spesso messa in dubbio dalla pratica e i cui costi manutentivi divengono spesso nuovi carichi per la collettività. Sulla base di una breve rassegna delle politiche sulla mobilità maggiormente implementate nella preparazione e gestione dei Grandi Eventi, il contributo evidenzia in maniera critica punti di forza e punti di debolezza delle esperienze analizzate in riferimento sia alla gestione del grande evento, sia in riferimento alla loro reale utilità per la collettività dopo che il grande evento è terminato. Nell’ultima parte del contributo si evidenziano i principali requisiti che le politiche sulla mobilità devono possedere affinché apportino reali vantaggi alla città anche una volta che il Grande Evento è terminato.The paper analyses, through different examples, the limits of the urban mobility policies implemented for mega events, highlighting the tendency to privilege the infrastructure realization, more than policies on services, whose real usefulness is often put in doubt from the practice and whose maintenance often become a new cost for the community. On the base of a short review of the mobility policies mainly implemented in the preparation and management of the mega events, the paper highlights, from a critical point of view, the strengths and weaknesses of some experiences with reference to the real usefulness of urban mobility for the community beyond the mega event. The outcomes and the so-called “legacy” of the mega events for the cities are very different. Mega sport events, like the Olympic Games, have often involved only the realization of works for the event while events like the International Expositions have determined the acquisition of

    Full Text Available O objetivo da investigação foi analisar vazões extremas ocorridas entre 9 e 14 de abril de 2011 na bacia do Rio Araguari-AP. A metodologia consistiu de três etapas principais: 1 re-análise da precipitação estimada pelo Modelo BRAMS (Brazilian in Development Regional Atmospheric Model System,utilizando como suporte a sinótica do mesmo período; 2 análise de vazão nas seções de monitoramento hidrológico em Porto Platon, Capivara e Serra do Navio (ADCP-Accustic Doppler Profiller Current; 3 análise estatística da série histórica de vazões máximas em Porto Platon utilizando distribuição de Gumbel. Observou-se que o modelo BRAMS capturou parcialmente o padrão do sistema de precipitação quando comparado com a análise sinótica e com os dados da literatura, mas demandando ainda otimização na representação de respostas hidrológicas extremas. Em Porto Platon foi registrada uma vazão recorde de 4036 m3/s, cujo comportamento foi analisado sob a ótica dos mecanismos disponíveis de monitoramento no Estado. Concluiu-se que tais eventos extremos são pouco detectáveis e oferecem riscos consideráveis aos usuários da bacia. A previsão de vazão, baseada na série hidrológica disponível, era de 100 anos de retorno, mas as análises revelaram que este período seria de 360 anos, indicando significativa fragilidade do sistema de previsão de eventos extremos no Estado.

O delineamento metodológico utilizado foi a meta análise (LUIZ, 2002. Por meio da busca por palavras chaves como previdência, social e fundos de pensão foram encontrados 33 artigos que abordavam o tema Previdência, cujos conteúdos foram categorizados segundo os seguintes critérios: distribuição anual dos artigos e dos eventos, autores, unidades federativas dos autores e do evento, abordagem metodológica, tipos de regimes, pesquisadores mais citados, publicação em periódicos e déficit da Previdência. Verificou-se que há mais publicações nos eventos do EnANPAD e não há predominância de nenhuma abordagem metodológica, além de um enfoque maior dos estudos em relação aos regimes complementares de previdência. Os resultados evidenciam a carência de estudos sobre Previdência Social devendo, pois, abordar mais profundamente questões relevantes para o contexto da administração pública. O artigo também evidencia as principais estratégias utilizadas pelos pesquisadores, norteando os demais estudiosos para preencher as lacunas teórico-metodológicas na área, a fim de aumentar as pesquisas que subsidiem o governo na tomada de decisão em relação às políticas previdenciárias.

    Full Text Available In some modern communication systems, as it is the case of WiMAX, it has been decided to implement Demand Assignment Multiple Access (DAMA solutions. End-users request transmission opportunities before accessing the system, which provides an efficient way to share system resources. In this paper, we briefly review the PHY and MAC layers of an OFDMA-based WiMAX system, and we propose to use a Network Utility Maximization (NUM framework to formulate the DAMA strategy foreseen in the uplink of IEEE 802.16. Utility functions are chosen to achieve fair solutions attaining different degrees of fairness and to further support the QoS requirements of the services in the system. Moreover, since the standard allocates resources in a terminal basis but each terminal may support several services, we develop a new decomposition technique, the coupled-decompositions method, that obtains the optimal service flow allocation with a small number of iterations (the improvement is significant when compared to other known solutions. Furthermore, since the PHY layer in mobile WiMAX has the means to adapt the transport capacities of the links between the Base Station (BS and the Subscriber Stations (SSs, the proposed PHY-MAC cross-layer design uses this extra degree of freedom in order to enhance the network utility.

  14. Constrained Balancing of Two Industrial Rotor Systems: Least Squares and Min-Max Approaches

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Rotor vibrations caused by rotor mass unbalance distributions are a major source of maintenance problems in high-speed rotating machinery. Minimizing this vibration by balancing under practical constraints is quite important to industry. This paper considers balancing of two large industrial rotor systems by constrained least squares and min-max balancing methods. In current industrial practice, the weighted least squares method has been utilized to minimize rotor vibrations for many years. One of its disadvantages is that it cannot guarantee that the maximum value of vibration is below a specified value. To achieve better balancing performance, the min-max balancing method utilizing the Second Order Cone Programming (SOCP with the maximum correction weight constraint, the maximum residual response constraint as well as the weight splitting constraint has been utilized for effective balancing. The min-max balancing method can guarantee a maximum residual vibration value below an optimum value and is shown by simulation to significantly outperform the weighted least squares method.

    New reseach in Russia, Germany and Israel has revealed the complex and multifaceted figure of Mirra Eitingon (1877-1947), the wife for 31 years of Dr. Max Eitingon. Her character and her background in the Russian-Jewish intelligentsia and theatrical milieu provided a lifelong inspiration for Max in his many cultural interests as well as in his psychoanalytic activities, in Berlin and later in Jerusalem. His devotion to Mirra as well as to her two sons from previous marriages (one of them was the leading Soviet nuclear physicist Yuli Khariton) also highlight Max's own generosity and kindness.

    Full Text Available O objetivo do estudo foi estimar a frequência e os fatores associados à ocorrência de eventos adversos pós-vacinação contra a influenza pandêmica A (H1N1 2009 em crianças com idade entre seis meses e dois anos. Participaram do estudo 156 crianças. Modelos multivariados de regressão de Cox foram construídos para avaliar a associação independente de cada covariável e a queixa de pelo menos um evento adverso. A força da associação foi medida pela hazard ratio e seus respectivos intervalos de 95% de confiança. Após a primeira dose, foi relatado algum tipo de evento adverso por 40,3% dos participantes e, após a segunda, por 35,5%. Os eventos sistêmicos foram mais frequentes que os locais, destaque para irritabilidade, diarreia e febre. As incidências de eventos adversos, no geral e sistêmicos, após a primeira dose, foram maiores nas crianças com doença concomitante/alergia em relação àquelas sem o agravo (HR = 3,43; IC95%: 1,34-8,77 e HR = 2,76; IC95%: 1,11-6,89. A maioria dos eventos foi de intensidade leve. Febre alta, vômito e diarreia motivaram a busca por serviços de saúde.The aim of this study was to estimate the frequency of adverse events following vaccination against pandemic influenza A (H1N1 2009 and associated factors in children from six months to two years of age (n = 156. Multivariate Cox regression was used to assess the independent associations between covariates and complaints of at least one adverse event.

    Student often face difficulties with using math in science, and this exploratory project seeks to address the underlying mechanisms that lead to these difficulties. This mixed-methods project includes the creation of two novel assessment surveys, the Mathematical Epistemic Games Survey (MEGS) and the Math Attitude and Expectations Survey (MAX). The MAX, a 30-question Likert-scale survey, focuses on the attitudes towards using mathematics of the students in a reformed introductory physics course for the life sciences (IPLS) which is part of the National Experiment in Undergraduate Education (NEXUS/Physics) developed at the University of Maryland (UMD). Preliminary results from the MAX are discussed with specific attention given to students' attitudes towards math and physics, opinions about interdisciplinarity, and the usefulness of physics in academic settings as well as in professional biological research and modern medicine settings.

    2009-01-01

    In this paper, we present a training technique of a Recurrent Radial Basis Function neural network for fault prediction. We use the Fuzzy Min-Max technique to initialize the k-center of the RRBF neural network. The k-means algorithm is then applied to calculate the centers that minimize the mean square error of the prediction task. The performances of the k-means algorithm are then boosted by the Fuzzy Min-Max technique.

    2015-09-01

    Soccer is the most popular sport worldwide, with a long history and currently more than 500 million active participants, of whom 300 million are registered football club members. On the basis of scientific findings showing positive fitness and health effects of recreational soccer, FIFA (Fédération Internationale de Football Association) introduced the slogan "Playing football for 45 min twice a week-best prevention of non-communicable diseases" in 2010. The objective of this paper was to perform a systematic review and meta-analysis of the literature to determine the effects of recreational soccer on maximal oxygen uptake (VO2max). Six electronic databases (MEDLINE, PubMed, SPORTDiscus, Web of Science, CINAHL and Google Scholar) were searched for original research articles. A manual search was performed to cover the areas of recreational soccer, recreational physical activity, recreational small-sided games and VO2max using the following key terms, either singly or in combination: recreational small-sided games, recreational football, recreational soccer, street football, street soccer, effect, maximal oxygen uptake, peak oxygen uptake, cardiorespiratory fitness, VO2max. The inclusion criteria were divided into four sections: type of study, type of participants, type of interventions and type of outcome measures. Probabilistic magnitude-based inferences for meta-analysed effects were based on standardised thresholds for small, moderate and large changes (0.2, 0.6 and 1.2, respectively) derived from between-subject standard deviations for baseline fitness. Seventeen studies met the inclusion criteria and were included in the systematic review and meta-analysis. Mean differences showed that VO2max increased by 3.51 mL/kg/min (95 % CI 3.07-4.15) over a recreational soccer training programme in comparison with other training models. The meta-analysed effects of recreational soccer on VO2max compared with the controls of no exercise, continuous running and strength

    2013-01-01

    Highlights: • A magnetic origin of cuprate superconductivity is plausible. • Cuprate loop currents are observed, close to predictions. • Pseudogap effects are seen above and below T c . -- Abstract: The basic physics of cuprate superconductivity is still much deliberated after 27 years of research. In contrast to phononic or polaronic roots, Varma’s theory promotes a magnetic origin. To probe cuprate magnetism, we examine zero field (ZF) muon-spin-rotation (μSR) data of RBa 2 Cu 3 O 7−δ (RBCO; R = Gd, Eu) especially near T c . Possible weak effects are analyzed using Maximum Entropy (MaxEnt, ME) to transform our μSR time series. Concerning predicted pseudogap loop currents, we have observed μSR signals in zero field for GdBCO above and now also below T c . These are near predicted fields of about 100 Oe. Using MaxEnt, we analyze transverse field (TF) μSR data of optimal doped EuBCO. Our focus is also on a temperature interval above T c to comprehend precursor effects. Our results point toward magnetic roots of cuprate superconductivity

  15. Efficacy of Metarhizium anisopliae isolate MAX-2 from Shangri-la, China under desiccation stress

    Science.gov (United States)

    2014-01-01

    Background Metarhizium anisopliae, a soil-borne entomopathogen found worldwide, is an interesting fungus for biological control. However, its efficacy in the fields is significantly affected by environmental conditions, particularly moisture. To overcome the weakness of Metarhizium and determine its isolates with antistress capacity, the efficacies of four M. anisopliae isolates, which were collected from arid regions of Yunnan Province in China during the dry season, were determined at different moisture levels, and the efficacy of the isolate MAX-2 from Shangri-la under desiccation stress was evaluated at low moisture level. Results M. anisopliae isolates MAX-2, MAC-6, MAL-1, and MAQ-28 showed gradient descent efficacies against sterile Tenebrio molitor larvae, and gradient descent capacities against desiccation with the decrease in moisture levels. The efficacy of MAX-2 showed no significant differences at 35% moisture level than those of the other isolates. However, significant differences were found at 8% to 30% moisture levels. The efficacies of all isolates decreased with the decrease in moisture levels. MAX-2 was relatively less affected by desiccation stress. Its efficacy was almost unaffected by the decrease at moisture levels > 25%, but slowly decreased at moisture levels molitor larvae under desiccation stress and in wet microhabitat. Local black patches were found on the cuticles of the insects, and the cadavers dried without fungal growth under desiccation stress. However, dark black internodes and fungal growth were found after death of the insects in the wet microhabitat. Conclusions MAX-2 showed significantly higher efficacy and superior antistress capacity than the other isolates under desiccation stress. The infection of sterile T. molitor larvae at low moisture level constituted a valid laboratory bioassay system in evaluating M. anisopliae efficacy under desiccation stress. PMID:24383424

    The Becton Dickinson (BD) PCR-based GeneOhm Cdiff assay has demonstrated a high sensitivity and specificity for detecting Clostridium difficile. Recently, the BD Max platform, using the same principles as BD GeneOhm, has become available in Australia. This study aimed to investigate the sensitivity and specificity of BD Max Cdiff assay for the detection of toxigenic C. difficile in an Australian setting. Between December 2013 and January 2014, 406 stool specimens from 349 patients were analysed with the BD Max Cdiff assay. Direct and enrichment toxigenic culture were performed on bioMérieux ChromID C. difficile agar as a reference method. isolates from specimens with discrepant results were further analysed with an in-house PCR to detect the presence of toxin genes. The overall prevalence of toxigenic C. difficile was 7.2%. Concordance between the BD Max assay and enrichment culture was 98.5%. The sensitivity, specificity, positive predictive value and negative predictive value for the BD Max Cdiff assay were 95.5%, 99.0%, 87.5% and 99.7%, respectively, when compared to direct culture, and 91.7%, 99.0%, 88.0% and 99.4%, respectively, when compared to enrichment culture. The new BD Max Cdiff assay appeared to be an excellent platform for rapid and accurate detection of toxigenic C. difficile.

    The need for a horse to be ridden while wearing a measurement device that allows unrestricted ventilation and gas exchange has hampered accurate measurement of its maximal oxygen consumption (V̇O 2 max) under field conditions. Design and validate a facemask with the potential to measure V̇O 2 max accurately in the field. Experiment with 6 × 6 Latin square design. Two variations of a mask and associated electronic control module (ECM) were designed to enable breath-by-breath measurement of airflows through two 7.8 cm diameter pneumotachometers located 7.5 cm in front of each narus. The ECM was comprised of an analogue-to-digital converter and a lithium-ion battery that provided power and signal filtering to the pneumotachometers and an oxygen sensing cell, and powered a pump connected to gas sampling ports between the nares and pneumotachometers. Airflow and oxygen content of inspired and expired gases were recorded through the ECM and electronically transferred to a notebook. V̇O 2 was determined from these recordings using a customised software program. Mask B encased the lower jaw. Mask R left the jaw free so the horse could wear a bit if ridden. V̇O 2 max and arterial blood gases were measured in 6 horses during multiple treadmill tests. Each mask was worn twice and results compared to those from an established open flow-through system (O) by ANOVA-RM (Pmasks. V̇O 2 max measures were reproducible for each mask. Intraclass correlation coefficient between raters = 0.99. Some rebreathing of expired air from mask dead space. Masks capable of measuring V̇O 2 max during treadmill exercise were developed, tested and found to be accurate. Mask R has potential application to measurement of V̇O 2 max under field conditions. © 2017 EVJ Ltd.

  5. MaxEnt-Based Ecological Theory: A Template for Integrated Catchment Theory

    Science.gov (United States)

    Harte, J.

    2017-12-01

    The maximum information entropy procedure (MaxEnt) is both a powerful tool for inferring least-biased probability distributions from limited data and a framework for the construction of complex systems theory. The maximum entropy theory of ecology (METE) describes remarkably well widely observed patterns in the distribution, abundance and energetics of individuals and taxa in relatively static ecosystems. An extension to ecosystems undergoing change in response to disturbance or natural succession (DynaMETE) is in progress. I describe the structure of both the static and the dynamic theory and show a range of comparisons with census data. I then propose a generalization of the MaxEnt approach that could provide a framework for a predictive theory of both static and dynamic, fully-coupled, eco-socio-hydrological catchment systems.

    Full Text Available O objetivo do trabalho proposto é detectar antecipadamente possíveis ocorrências de eventos convectivos severos, por meio do monitoramento das saídas do modelo de previsão numérica de tempo Eta, para cada intervalo de previsão e para um conjunto de variáveis selecionadas. O período de estudo estende-se de janeiro a fevereiro de 2007. Classificadores foram desenvolvidos pela abordagem de similaridade de vetores e de conjuntos aproximativos, de forma a identificar saídas do modelo Eta que possam ser associados a esses eventos. Assumiu-se como premissa que os eventos convectivos severos possam ser correlacionados com grande número de ocorrências de descargas elétricas atmosféricas. Os classificadores agruparam as saídas do modelo Eta, compostas por essas variáveis, com base na densidade de ocorrência de descargas elétricas atmosféricas nuvem-solo. Ambos os classificadores apresentaram bom desempenho para os testes realizados para um período de dois meses escolhido para três mini-regiões selecionadas do território brasileiro.This work aims the early detection of possible occurrences of severe convective events in Central and Southeast Brazil by means of monitoring the output of the Eta numerical weather prediction model for each forecasted time interval and for a selected set of variables. The studied period ranges from January to February 2007. Classifiers were developed by two approaches, vector similarity and rough sets, in order to identify Eta outputs that can be associated to such events. It was assumed that severe convective events can be correlated to a large number of atmospheric electric discharges. The classifiers grouped the Eta meteorological model outputs for these selected variables based on the density of occurrences of cloud-to-ground atmospheric electrical discharges. Both classifiers show good performance for the chosen 2-month period at the three selected mini-regions of the Brazilian territory.

    In this paper, we propose Max Connectivity grooming in WDM mesh networks under static lightpath connection requests. The grooming and wavelength conversion resources are placed at the nodes having maximum connections. We propose a heuristic genetic algorithm (GA) model to solve grooming, routing and wavelength assignment. The GA algorithm has been used to optimize the cost of grooming and wavelength conversion resources. The blocking probability has been investigated under different lightpath connections. The performance of Max Connectivity grooming has been compared with other grooming policies. Our results indicate the improvement of resource utilization with minimum blocking probability.

    We examined the effect of β-alanine supplementation plus sodium bicarbonate on high-intensity cycling capacity. Twenty males (age = 25 ± 5 yr, height = 1.79 ± 0.06 m, body mass = 80.0 ± 10.3 kg) were assigned to either a placebo (P) or a β-alanine (BA; 6.4 g·d(-1) for 4 wk) group based on power max, completing four cycling capacity tests at 110% of power max (CCT110%) to determine time to exhaustion (TTE) and total work done. A CCT(110%) was performed twice (habituation and baseline) before supplementation (with maltodextrin [MD]) and twice after supplementation (with MD and with sodium bicarbonate [SB]), using a crossover design with 2 d of rest between trials, creating four study conditions (PMD, PSB, BAMD, and BASB). Blood pH, Lactate, bicarbonate and base excess were determined at baseline, before exercise, immediately after exercise, and 5 min after exercise. Data were analyzed using repeated-measures ANOVA. TTE was increased in all conditions after supplementation (+1.6% PMD, +6.5% PSB, +12.1% BAMD, and +16.2% BASB). Both BAMD and BASB resulted in significantly improved TTE compared with that before supplementation (P ≤ 0.01). Although further increases in TTE (4.1%) were shown in BASB compared with BAMD, these differences were not significant (P = 0.74). Differences in total work done were similar to those of TTE. Blood bicarbonate concentrations were significantly (P ≤ 0.001) elevated before exercise in PSB and BASB but not in PMD or BAMD. Blood lactate concentrations were significantly elevated after exercise, remaining elevated after 5 min of recovery (P ≤ 0.001) and were highest in PSB and BASB. Results show that BA improved high-intensity cycling capacity. However, despite a 6-s (∼4%) increase in TTE with the addition of SB, this did not reach statistical significance, but magnitude-based inferences suggested a ∼70% probability of a meaningful positive difference.

    Full Text Available Os Distúrbios Ondulatórios de Leste (DOL’s são perturbações dos ventos alísios que, no Nordeste do Brasil, geralmente se associam a eventos extremos de precipitação. Este trabalho analisa o comportamento evolutivo de um DOL que atingiu o Estado de Pernambuco em junho de 2010, provocando inundações e grandes prejuízos humanos e econômicos. O recorte escolhido para análise foi a bacia hidrográfica do rio Una, que teve 11 municípios afetados. A análise do evento baseou-se na interpretação de imagens GOES-12 realçadas e TRMM. Constatou-se que a análise de imagens GOES-12 isoladas não produz uma resposta eficaz, no entanto, quando associada a mais informações, chega a uma resposta concisa e de extrema importância para os estudos relacionados a eventos climáticos. Para avaliação da vulnerabilidade à inundação das diversas sedes municipais da bacia do Una, utilizou-se um estimador de densidade Kernel baseado nos valores de magnitude da rede de drenagem. Os resultados indicaram que mesmo áreas naturalmente menos vulneráveis podem ser seriamente afetadas em função do montante precipitado.

    The population structure has changed with the aging of population. In the present, elders account for 10.63% of the domestic population and the percentage is still gradually climbing. In other words, the demand for emergency services among elders in home environment is expected to grow in the future. In order to improve the efficiency and quality of emergency care, information technology should be effectively utilized to integrate medical systems and facilities, strengthen human-centered operation designs, and maximize the overall performance. The improvement in the quality and survival rate of emergency care is an important basis for better life and health of all people. Through integrated application of medical information systems and information communication technology, this study proposes a WiMAX-based emergency care system addressing the public demands for convenience, speed, safety, and human-centered operation of emergency care. This system consists of a healthcare service center, emergency medical service hospitals, and emergency ambulances. Using the wireless transmission capability of WiMAX, patients' physiological data can be transmitted from medical measurement facilities to the emergency room and emergency room doctors can provide immediate online instructions on emergency treatment via video and audio transmission. WiMAX technology enables the establishment of active emergency medical services.

    The aim of this study was to determine whether the early response in weekly measures of HRV, when derived from a smartphone application, were related to the eventual change in VO2max following an off-season training program in female soccer athletes. 9 female collegiate soccer players participated in an 11-week off-season conditioning program. In the week immediately before and after the training program, each participant performed a test on a treadmill to determine maximal oxygen consumption (VO2max). Daily measures of the log-transformed root mean square of successive R-R intervals (lnRMSSD) were performed by the participants throughout week 1 and week 3 of the conditioning program. The mean and coefficient of variation (CV) lnRMSSD values of week 1 showed small (r=- 0.13, p=0.74) and moderate (r=0.57, p=0.11), respectively, non-significant correlations to the change in VO2max at the end of the conditioning program (∆VO2max). Significant and near-perfect correlation was found between the change in the weekly mean lnRMSSD values from weeks 1 and 3 (∆lnRMSSDM) and ∆VO2max (r=0.90, p=0.002). The current results have identified that the initial change in weekly mean lnRMSSD from weeks 1 to 3 of a conditioning protocol was strongly associated with the eventual adaptation of VO2max. © Georg Thieme Verlag KG Stuttgart · New York.

    MAXED was developed to apply the maximum entropy principle to the unfolding of neutron spectrometric measurements. The approach followed in MAXED has several features that make it attractive: it permits inclusion of a priori information in a well-defined and mathematically consistent way, the algorithm used to derive the solution spectrum is not ad hoc (it can be justified on the basis of arguments that originate in information theory), and the solution spectrum is a non-negative function that can be written in closed form. This last feature permits the use of standard methods for the sensitivity analysis and propagation of uncertainties of MAXED solution spectra. We illustrate its use with unfoldings of NE 213 scintillation detector measurements of photon calibration spectra, and of multisphere neutron spectrometer measurements of cosmic-ray induced neutrons at high altitude (approx 20 km) in the atmosphere.
