    Pulse is often understood as a feature of a (quasi-) isochronous event sequence that is picked up by an entrained subject. However, entrainment does not only occur between quasi-periodic rhythms. This paper demonstrates the expression of pulse by subjects listening to non-periodic musical stimuli and investigates the processes behind this behaviour. The stimuli are extracts from the introductory sections of North Indian (Hindustani) classical music performances (alap, jor and jhala). The first of three experiments demonstrates regular motor responses to both irregular alap and more regular jor sections: responses to alap appear related to individual spontaneous tempi, while for jor they relate to the stimulus event rate. A second experiment investigated whether subjects respond to average periodicities of the alap section, and whether their responses show phase alignment to the musical events. In the third experiment we investigated responses to a broader sample of performances, testing their relationship to spontaneous tempo, and the effect of prior experience with this music. Our results suggest an entrainment model in which pulse is understood as the experience of one's internal periodicity: it is not necessarily linked to temporally regular, structured sensory input streams; it can arise spontaneously through the performance of repetitive motor actions, or on exposure to event sequences with rather irregular temporal structures. Greater regularity in the external event sequence leads to entrainment between motor responses and stimulus sequence, modifying subjects' internal periodicities in such a way that they are either identical or harmonically related to each other. This can be considered as the basis for shared (rhythmic) experience and may be an important process supporting 'social' effects of temporally regular music. PMID:25849357

  9. Inhibition of alanine racemase by alanine phosphonate: detection of an imine linkage to pyridoxal 5'-phosphate in the enzyme-inhibitor complex by solid-state 15N nuclear magnetic resonance

    International Nuclear Information System (INIS)

    Inhibition of alanine racemase from the Gram-positive bacterium Bacillus stearothermophilus by (1-aminoethyl)phosphonic acid (Ala-P) proceeds via a two-step reaction pathway in which reactivation occurs very slowly. In order to determine the mechanism of inhibition, the authors have recorded low-temperature, solid-state 15N NMR spectra from microcrystals of the [15N]Ala-P-enzyme complex, together with spectra of a series of model compounds that provide the requisite database for the interpretation of the 15N chemical shifts. Proton-decoupled spectra of the microcrystals exhibit a line at ∼ 150 ppm, which conclusively demonstrates the presence of a protonated Ala-P-PLP aldimine and thus clarifies the structure of the enzyme-inhibitor complex. They also report the pH dependence of Ala-P binding to alanine racemase

O governo federal, por meio do Ministério dos Transportes, anunciou a sua intenção de reconstruir e pavimentar a Rodovia BR-319, que está abandonada desde 1988. A Secretaria de Estado do Meio Ambiente e Desenvolvimento Sustentável (SDS, do Governo do Estado do Amazonas, e o Ministério do Meio Ambiente (MMA têm planos para criar uma série de áreas protegidas dentro da ALAP. Nossa simulação compara cenários com e sem as reservas de proteção propostas. A reconstrução e a pavimentação da rodovia são presumidas a serem finalizadas em 2011, com a abertura de estradas laterais associadas em datas especificadas ao longo do período 2014-2024. A simulação de desmatamento acopla os programas computacionais DINAMICA e Vensim, e incorpora uma série de inovações para permitir que o total de desmatamento responda à melhoria do acesso por estradas, baseado em uma parametrização da relação entre desmatamento e expansão viária observada em imagens de satélite de uma área no noroeste de Rondônia, adjacente à ALAP. A expansão modelada de estradas endógenas não está limitada por uma presunção de um processo de desmatamento puramente "dirigido pela demanda". Esta suposição impediu que outros modelos de desmatamento na Amazônia, representassem o efeito sobre o desmatamento total causado por decisões relativas às reservas (visto que o desmatamento total especificado externamente, baseado na demanda, implica em um "vazamento" de 100% de qualquer benefício de criação de reservas. A mesma limitação se aplica ao efeito de estradas em modelos dirigidos por demanda. Os resultados obtidos pelo nosso modelo foram validados

    Total syntheses and complete characterizations of singly substituted PheCN -based analogs of alamethicin AlaP, which is active on model and natural membranes, and the TM peptide, which inserts in a transmembrane orientation in lipid bilayers, are reported. The syntheses of the AlaP analogs were performed in solution, while those of TM and its analogs were carried out by solid phase. Using the cyanophenyl fluorescence and infrared (IR) absorption probe, an in-depth investigation of the self-association, membrane-interacting, permeabilizing, and orientation properties of these peptides were conducted. The aromatic residue incorporated induces only a negligible modification to the properties of the parent peptides. The PheCN IR absorption band was located between 2228 and 2230 cm(-1) for all peptides, irrespective of the position of labeling. By contrast, as the width of this band varied significantly with the depth of probe insertion in the bilayer, it could represent a good marker of the PheCN position in phospholipid membranes.

  4. Are we ready to apply the de minimis concept to standard setting: a historical approach

    International Nuclear Information System (INIS)

    The pros and cons of the de minimis concept is discussed from a historical point of view. The purpose is first to indicate how long ago many common occupational hazards were recognized and second to conclude that there had to be exposure levels that were essentially trivial, i.e., de minimis. Some aspects of the history of radiation protection are presented. The topics of discussion include: empiricism; the tolerance dose; the maximum permissible exposure dose; as low as possible dose (ALAP) and as low as reasonable achievable (ALARA); and the challenge of the '80s. In the '80s with the strong movement to use risk as a basis for both radiation and chemical standards, the need for adding the concept of a trivial risk has taken hold. Some examples of possible de minimis levels, as well as some of the problems and current activities, are presented

  6. Energy-efficient fault tolerance in multiprocessor real-time systems

    Science.gov (United States)

    Guo, Yifeng

    The recent progress in the multiprocessor/multicore systems has important implications for real-time system design and operation. From vehicle navigation to space applications as well as industrial control systems, the trend is to deploy multiple processors in real-time systems: systems with 4 -- 8 processors are common, and it is expected that many-core systems with dozens of processing cores will be available in near future. For such systems, in addition to general temporal requirement common for all real-time systems, two additional operational objectives are seen as critical: energy efficiency and fault tolerance. An intriguing dimension of the problem is that energy efficiency and fault tolerance are typically conflicting objectives, due to the fact that tolerating faults (e.g., permanent/transient) often requires extra resources with high energy consumption potential. In this dissertation, various techniques for energy-efficient fault tolerance in multiprocessor real-time systems have been investigated. First, the Reliability-Aware Power Management (RAPM) framework, which can preserve the system reliability with respect to transient faults when Dynamic Voltage Scaling (DVS) is applied for energy savings, is extended to support parallel real-time applications with precedence constraints. Next, the traditional Standby-Sparing (SS) technique for dual processor systems, which takes both transient and permanent faults into consideration while saving energy, is generalized to support multiprocessor systems with arbitrary number of identical processors. Observing the inefficient usage of slack time in the SS technique, a Preference-Oriented Scheduling Framework is designed to address the problem where tasks are given preferences for being executed as soon as possible (ASAP) or as late as possible (ALAP). A preference-oriented earliest deadline (POED) scheduler is proposed and its application in multiprocessor systems for energy-efficient fault tolerance is

  9. Risk and safety in the nuclear industry and conventional norms of society

    International Nuclear Information System (INIS)

    In the present study the societal acceptance of various risks is analyzed and rules of risk acceptance as a function of different parameters are spelled out. The monetary value of a human life is estimated, based on investments in safety of different human activities. The acceptable risks and safety investments in different human activities are then compared with risks and safety investments of the nuclear industry. Safety investments required to reduce the radioactivity releases and risks from nuclear power stations to ALAP levels are taken as a study case. It is found that risks in the nuclear industry are several orders of magnitude lower and safety investments per human life saved are several orders of magnitude higher, as compared with risks and safety investments in other human activities. It is also shown that the incremental safety investments needed to further reduce the radiation doses in the environment during normal and continuous operation of nuclear plants are extravagantly high as compared to safety investments in other human activities and in other facets of human life. Considering that there is a limit to the economic means available, societal expenditures for reducing risks should by spread, as much as possible, over all human activities to get the maximum return from investments.

    Az elmúlt évek kutatómunkái nyomán megállapítható, hogy a mikro-, kis- és középvállalkozások (továbbiakban kkv-k) számára az életpálya alapú elemző rendszerek egyre inkább megalapozott és segítőkész eszközként állnak rendelkezésre a mindennapos erőpróbák megvívásához. Kutatásaink során összegyűjtöttük a korábban megalkotott életpályamodelleket, és összefoglaltuk a korábbi modellek előnyeit illetve rugalmatlanságait. A kapcsolódó szakirodalmi háttér feldolgozásán túl az elmúlt időszakban saját...

  12. Munkaszervezés a lean termelésben – mit magyaráznak a termelésmenedzsment koncepciók = Work organization in lean production – what production concepts explain

    A tanulmány a lean termelés munkaszervezését három termelésmenedzsment koncepció segítségével vizsgálja. Az egyes koncepciók a szervezet eltérő metszeteit érintik: (1) a termék-folyamat mátrix (Hayes és Wheelwright, 1979) a termék és a folyamat jellemzőit helyezi középpontba. A lean hatására a szervezet a mátrixban a nagyobb választék és a folyamat alapú működés (nagyobb függőség) irányába mozdul el. Az elmozdulást üzemi szinten a magas elkötelezettségű munkavégzési rendszer gyakorlatainak be...

  13. A szövetkezeti identitás - egy dinamikus megközelítés a szövetkezetek fejlődésének gazdasági nézőpontú elemzésére

    A tanulmány a nyugat-európai szövetkezés lényegét és fejlődési irányait vizsgálja. A szövetkezeti rendszerek elemzéséhez szükség van az úgynevezett szövetkezetiidentitás- felfogás elemeinek és kapcsolódásainak vizsgálatára. A koncepció legfontosabb részei: a szövetkezet definíciója, a szövetkezetek alapvető céljai és az elérésükhöz szükséges funkciók (szerepek), valamint az úgynevezett szövetkezeti alapelvek. A felfogás segítségével végzett elemzés fő állítása, hogy a holland esetben az alape...

  14. Environmental Development Plan (EDP): advanced isotope separation

    International Nuclear Information System (INIS)

    This Environmental Development Plan (EDP) identifies and examines the environmental, safety, health, and socioeconomic (ES and H) issues and corresponding requirements associated with the ERDA research, development, and demonstration of the Advanced Isotope Separation (AIS) program. This EDP has been limited to the consideration of (1) overall AIS processes from feed material to product recovery, (2) laser processes (molecular and atomic vapor), (3) the plasma process, and (4) the necessary research and development activities. The key issues and requirements identified in this EDP encompass items specific to the AIS technology and items which are generic to the nuclear fuel cycle (including AIS) or multiple components of the fuel cycle. The key specific issues and requirements addressed are (1) the proliferation of this sensitive technology for the production of weapons grade material and (2) the potential occupational health effects from lasers or process chemicals and exposure to magnetic fields and electromagnetic fields. The key generic issues (which are also AIS process related are (1) the needs for the development of ''as low as practicable'' (ALAP) emission capabilities for effluents and (2) the identification of the radioactive contaminants in the AIS feed material.The key environmental planning elements for implementing the identified requirements are (1) scheduling the needs against the three critical technology development milestones: process selection (1981), operation of an engineering demonstration facility (EDF) (1984), and operation of a uranium tails stripper module (1990); and (2) identification of NEPA requirements and schedules, one for the process selection and construction of the EDF and one for the decision to construct and operate the stripper module
