    The symptom commonly associated with whole body irradiation is diarrhoea, a still quite obscure phenomenon, which leads to decreased chance of cure of irradiated people. The aim of this study was to provide evidence for dysfunction of intestinal water and electrolyte transport regulation by the enteric nervous system after exposure to ionising radiation. This study shows decreased capacity of enteric nervous system to influence colonic transport 3days after irradiation, correlated to a diminished response to a neurotransmitter: serotonin. Radio-induced diarrhea may result from epithelial structural injury but also from impaired regulatory processes of intestinal transport. L'un des symptômes majeurs d'une irradiation corporelle totale ou abdominale est l'apparition de diarrhées, dont les causes sont encore mal connues, et qui mettent en jeu le pronostique vital de l'individu irradié. Cette étude vise à mettre en évidence l'atteinte de la régulation du transport intestinal d'eau et d'électrolytes par les rayonnements ionisants. On observe une diminution de la capacité du système nerveux entérique à influencer le transport colique 3jours après irradiation, corrélée à une diminution de la réponse épithéliale à un neurotransmetteur : la sérotonine. Les diarrhées radio-induites résulteraient d'une atteinte structurelle de l'épithélium mais également des processus de régulation du transport intestinal.

    A series of tests were performed at Oak Ridge National Laboratory (ORNL) to evaluate and characterize the radiological response of a ''Cricket'' radiation detection system. The ''Cricket'' is manufactured by RAD/COMM Systems Corp., which is located in Ontario, Canada. The system is designed to detect radioactive material that may be contained in scrap metal. The Cricket's detection unit is mounted to the base of a grappler and monitors material, while the grappler's tines hold the material. It can also be used to scan material in an attempt to isolate radioactive material if an alarm occurs. Testing was performed at the Environmental Effects Laboratory located at ORNL and operated by the Engineering Science and Technology Division. Tests performed included the following: (1) Background stability, (2) Energy response using {sup 241}Am, {sup 137}Cs, and {sup 60}Co, (3) Surface uniformity, (4) Angular dependence, (5) Alarm actuation, (6) Alarm threshold vs. background, (7) Shielding, (8) Response to {sup 235}U, (9) Response to neutrons using unmoderated {sup 252}Cf, and (10) Response to transient radiation. This report presents a summary of the test results. Background measurements were obtained prior to the performance of each individual test.

    The Environmental Effects Laboratory of the Engineering Science and Technology Division of Oak Ridge National Laboratory performed a series of tests to further evaluate and characterize the radiological response of a ''Cricket'' radiation detection system. The Cricket, manufactured by Rad/Comm Systems Corporation of Ontario, Canada, is designed to detect radioactive material that may be contained in scrap metal. The Cricket's detection unit is designed to be mounted to the base of a grappler, allowing it to monitor material while the material is being held by the grappler tines. The Cricket was tested for background stability, energy response, spherical response, surface uniformity, angular dependence, and alarm actuation. Some of these tests were repeated from a prior test of a Cricket at the Environmental Effects Laboratory as reported in ORNL/TM-2002/94. Routine environmental tests--normal temperature and relatively humidity--were also performed as part of this testing process. Overall, the Cricket performed well during the testing process. The design of the instrument and the inherent photon energy of the radionuclides had some affect on portions of the tests but do not detract from the value-added benefits of the Cricket's detection capabilities.

    2015-12-04

    The Consortium for Algal Biofuel Commercialization (CAB-Comm) was established in 2010 to conduct research to enable commercial viability of alternative liquid fuels produced from algal biomass. The main objective of CAB-Comm was to dramatically improve the viability of algae as a source of liquid fuels to meet US energy needs, by addressing several significant barriers to economic viability. To achieve this goal, CAB-Comm took a diverse set of approaches on three key aspects of the algal biofuels value chain: crop protection; nutrient utilization and recycling; and the development of genetic tools. These projects have been undertaken as collaboration between six academic institutions and two industrial partners: University of California, San Diego; Scripps Institution of Oceanography; University of Nebraska, Lincoln; Rutgers University; University of California, Davis; Johns Hopkins University; Sapphire Energy; and Life Technologies.

    This paper describes a collaborative FAA and NASA experiment using 22 commercial airline pilots to determine the effect of using Datalink Communication (Data Comm) to issue messages in busy, terminal area operations. Four conditions were defined that span current day to future flight deck equipage levels (voice communication only, Data Comm only, Data Comm with Moving Map Display, Data Comm with Moving Map displaying taxi route), and each condition was used to create an arrival and a departure scenario at the Boston Logan Airport. These eight scenarios were repeated twice for a total of 16 scenarios for each of the eleven crews. Quantitative data was collected on subject reaction time and eye tracking information. Questionnaires collected subjective feedback on workload and acceptability to the flight crew for using Data Comm in a busy terminal area. 95% of the Data Comm messages were responded to by the flight crew within one minute; however, post experiment debrief comments revealed almost unanimous consensus that two minutes was a reasonable expectation for crew response. Eye tracking data indicated an insignificant decrease in head-up time for the Pilot Flying when Data Comm was introduced; however, the Pilot Monitoring had significantly less head-up time. Data Comm workload was rated as operationally acceptable by both crew members in all conditions in flight at any altitude above the Final Approach Fix in terms of response time and workload. Results also indicate the use of Data Comm during surface operations was acceptable, the exception being the simultaneous use of voice, Data Comm, and audio chime required for an aircraft to cross an active runway. Many crews reported they believed Data Comm messages would be acceptable after the Final Approach Fix or to cross a runway if the message was not accompanied by a chime and there was not a requirement to immediately respond to the uplink message.

    Data comm is a new technology proposed in future air transport system as a potential tool to provide comprehensive data connectivity. It is a key enabler to manage 4D trajectory digitally, potentially resulting in improved flight times and increased throughput. Future concepts with data comm integration have been tested in a number of human-in-the-loop studies but analyzing the results has proven to be particularly challenging because future traffic environment in which data comm is fully enabled has assumed high traffic density, resulting in data set with large amount of information. This paper describes the motivation, design, current and potential future application of Visual Data Comm (VDC), a tool for visualizing data developed in Java using Processing library which is a tool package designed for interactive visualization programming. This paper includes an example of an application of VDC on data pertaining to the most recent Multi Sector Planner study, conducted at NASA s Airspace Operations Laboratory in 2009, in which VDC was used to visualize and interpret data comm activities

    2012-01-01

    The purpose of this pilot-in-the-loop aircraft taxi simulation was to evaluate a NextGen concept for surface trajectory-based operations (STBO) in which air traffic control (ATC) issued taxi clearances with a required time of arrival (RTA) by Data Communications (DataComm). Flight deck avionics, driven by an error-nulling algorithm, displayed the speed needed to meet the RTA. To ensure robustness of the algorithm, the ability of 10 two-pilot crews to meet the RTA was tested in nine experimental trials representing a range of realistic conditions including a taxi route change, an RTA change, a departure clearance change, and a crossing traffic hold scenario. In some trials, these DataComm taxi clearances or clearance modifications were accompanied by 'preview' information, in which the airport map display showed a preview of the proposed route changes, including the necessary speed to meet the RTA. Overall, the results of this study show that with the aid of the RTA speed algorithm, pilots were able to meet their RTAs with very little time error in all of the robustness-testing scenarios. Results indicated that when taxi clearance changes were issued by DataComm only, pilots required longer notification distances than with voice communication. However, when the DataComm was accompanied by graphical preview, the notification distance required by pilots was equivalent to that for voice.

    2014-01-01

    This paper proposes VibeComm, a novel communication method for smart devices using a built-in vibrator and accelerometer. The proposed approach is ideal for low-rate off-line communication, and its communication medium is an object on which smart devices are placed, such as tables and desks. When more than two smart devices are placed on an object and one device wants to transmit a message to the other devices, the transmitting device generates a sequence of vibrations. The vibrations are propagated through the object on which the devices are placed. The receiving devices analyze their accelerometer readings to decode incoming messages. The proposed method can be the alternative communication method when general types of radio communication methods are not available. VibeComm is implemented on Android smartphones, and a comprehensive set of experiments is conducted to show its feasibility. PMID:25390406

  17. Using InterComm Enhanced ESMF to Couple TIME-GCM and CAM

    2008-12-01

    This project uses the Earth System Modeling Framework (ESMF) and InterComm to produce a TIME-GCM and CAM coupled model. This project will demonstrate a new ESMF capability for coupling models running as separate executables. This capability is based on the InterComm library. InterComm is a runtime library and programming model for coupling separately executing parallel (and sequential programs), and is being used as the component coupling technology within the NSF Center for Integrated Space Weather Modeling. ESMF interfaces to InterComm have been contributed to the ESMF code repository, making it easy to use InterComm to transfer data into and out of ESMF components such as CAM. This project's work to couple TIME-GCM and CAM is motivated by the goal of understanding the day-to-day behavior of the ionosphere-thermosphere system. Doing this requires unraveling the relative strengths of forcing mechanisms of the I-T system, including solar ultraviolet, extreme-ultraviolet, and X-ray fluxes, magnetospheric processes resulting in geomagnetic activity and auroral effects, and propagation of dynamical variations driven by lower atmosphere weather and middle atmosphere tides. The National Center for Atmospheric Research (NCAR) Thermosphere - Ionosphere - Mesosphere -Electrodynamic - Global Circulation Model (TIME-GCM) is used to simulate this region depending on its forcing by the Sun. Recent work on improving the forcing of this model by including an improved description of the Extreme Ultra Violet (EUV) radiation has increased its ability to predict observed parameters such as satellite drag, but it does not capture all the observed hemispheric asymmetries. The implication is that forcing from the lower atmosphere, which is clearly asymmetric due to the location of continental masses, and is known to have very different dynamical features at solstices, is controlling the thermosphere. However, the TIME-GCM, with its 30-km lower boundary, does not contain these effects

    This document describes a collaborative FAA/NASA experiment using 22 commercial airline pilots to determine the effect of using Data Comm to issue messages during busy, terminal area operations. Four conditions were defined that span current day to future flight deck equipage: Voice communication only, Data Comm only, Data Comm with Moving Map Display, and Data Comm with Moving Map displaying taxi route. Each condition was used in an arrival and a departure scenario at Boston Logan Airport. Of particular interest was the flight crew response to D-TAXI, the use of Data Comm by Air Traffic Control (ATC) to send taxi instructions. Quantitative data was collected on subject reaction time, flight technical error, operational errors, and eye tracking information. Questionnaires collected subjective feedback on workload, situation awareness, and acceptability to the flight crew for using Data Comm in a busy terminal area. Results showed that 95% of the Data Comm messages were responded to by the flight crew within one minute and 97% of the messages within two minutes. However, post experiment debrief comments revealed almost unanimous consensus that two minutes was a reasonable expectation for crew response. Flight crews reported that Expected D-TAXI messages were useful, and employment of these messages acceptable at all altitude bands evaluated during arrival scenarios. Results also indicate that the use of Data Comm for all evaluated message types in the terminal area was acceptable during surface operations, and during arrivals at any altitude above the Final Approach Fix, in terms of response time, workload, situation awareness, and flight technical performance. The flight crew reported the use of Data Comm as implemented in this experiment as unacceptable in two instances: in clearances to cross an active runway, and D-TAXI messages between the Final Approach Fix and 80 knots during landing roll. Critical cockpit tasks and the urgency of out-the window scan made the

    1999-01-01

    Recently, NASA's Jet Propulsion Laboratory completed a Mars Exploration Program Architecture Definition Study with strong international participation. The recommendations of this study include establishment of a low cost in-situ communications and navigation satellite network to provide enabling and enhancing support for the international exploration of Mars. This would be the first step toward establishing a "virtual presence throughout the solar system" as called for in NASA's Strategic Plan. Response to the proposed comm/nav satellite network has been very favorably received, as reflected by the inclusion of a line item in NASA's budget submittal to Congress, which provides funding for implementation of the network with first launch in the 2003 opportunity. Funding has already been provided for a phase A study being conducted this year. This paper presents the planned implementation of the comm/nav network, which will utilize microsats based on a multi-mission spacecraft bus being designed for launch by the Ariane 5 as a secondary payload. A companion paper at this conference, entitled "The Multi-Purpose Mars Micro-Mission System Design Utilizing Ariane 5 Piggyback Launch", describes the multimission bus design. This paper addresses the application of the multi-mission bus to the comm/nav microsat mission. Following an introduction, which provides the background that has led to the proposed comm/nav network, the paper discusses the projected user needs with emphasis on the various possible robotic missions (landers, rovers, ascent vehicles, balloons, aircraft, etc.) progressing toward eventual piloted missions. Next, the paper describes the concept for an evolving network of comm/nav microsats and the expected capability to satisfy the user needs. Results of communications and navigation performance analysis are summarized for attractive satellite constellation configurations. The important comm/nav microsat functional requirements on the multi

    Cette these presente la trajectoire et les resultats d'une recherche dont l'objectif global est de developper un modele educationnel integrant l'ethique de l'environnement comme dimension transversale de l'education en sciences et en technologies. Face au paradigme positiviste toujours dominant dans l'enseignement des sciences, il a semble utile d'ouvrir un espace de reflexion et de proposer, sous forme d'un modele formel, une orientation pedagogique qui soit plus en resonance avec quelques-unes des preoccupations fondamentales de notre epoque: en particulier celle qui concerne la relation de humain avec son environnement et plus specifiquement, le role de la science dans le faconnement d'une telle relation, par sa contribution a la transformation des conditions de vie, au point de compromettre les equilibres naturels. En fonction de cette problematique generale, les objectifs de la recherche sont les suivants: (1) definir les elements paradigmatiques, theoriques et axiologiques du modele educationnel a construire et (2) definir ses composantes strategiques. De caractere theorico-speculatif, cette recherche a adopte la demarche de l'anasynthese, en la situant dans la perspective critique de la recherche en education. Le cadre theorique de cette these s'est construit autour de quatre concepts pivots: modele educationnel, education en sciences et en technologies, transversalite educative et ethique de l'environnement. Ces concepts ont ete clarifies a partir d'un corpus textuel, puis, sur cette base, des choix theoriques ont ete faits, a partir desquels un prototype du modele a ete elabore. Ce prototype a ensuite ete soumis a une double validation (par des experts et par une mise a l'essai), dans le but d'y apporter des ameliorations et, a partir de la, de construire un modele optimal. Ce dernier comporte deux dimensions: theorico-axiologique et strategique. La premiere s'appuie sur une conception de l'education en sciences et en technologies comme appropriation d

    Introduction Une étude a été menée afin de déterminer le taux d'acceptabilité de 400µg de misoprostol par voie sublinguale comme traitement de première intention de l'avortement incomplet et de préciser le taux d'avortement complet ou vacuité utérine. Méthodes Les femmes éligibles avaient un diagnostic clinique d'avortement incomplet avec une taille utérine inférieure à celle d'un utérus de 12 semaines d'aménorrhées (SA). Chacune a reçu 400µg de misoprostol par voie sublinguale. Les femmes ont été revues après une semaine. A J7, celles qui n'avaient pas complètement expulsé ont eu le choix entre une nouvelle consultation de suivi à J14 et la pratique d'une évacuation chirurgicale immédiate. Résultats 145 patientes ont été éligibles et ont toutes accepté la méthode (100%). L’âge moyen était de 25,9 ± 6 ans. A J7, 120 patientes étaient guéries (85,7%). A J14, le taux de réussitea été de 95,7% soit 134 patientes guéries. Les patientes guéries ont déclaré être très satisfaites (57,5%), satisfaites (41,8%) et insatisfaite (0,7%). Au total,128 femmes (95,5%) ont dit être prêtes à utiliser de nouveau le misoprostol comme méthode d’évacuation utérine en cas d'avortement incomplet. Conclusion L’étude démontre que le 400µg misoprostol par voie sublinguale nous permet de prendre en charge d'une manière adéquate l'avortement incomplet surtout dans les pays à faible ressource et notamment dans les structures sanitaires de première ligne ou éloignées.

    The parasitic protozoan Toxoplasma gondii has been examined with the electron microscope in order to study the fine structure and the formation of the membranes surrounding the cell. The study of the ultrastructure of the membranes covering the parasite shows the existence of a three-membraned complex. Only the outer membrane is considered to be the plasma membrane; the two membranes below it form an inseparable whole of changeable molecular architecture (modifications in appearance depending on the methods of fixation, local differentiation). During reproduction, which takes place by fission or more often by endogeny, the membranes of the daughter individuals are formed from the membranes of the parent. At first the middle and inner membranes of the parent extend, separating the cytoplasm of the daughter cells from that of the parent. The three-membrane complex of the endozoites is completed at the time of their liberation; the external membrane of the parent covers the leaving endozoites; thus, the plasma membrane of the daughter cells derives also from that of the parent. These findings on the origin and role of limiting membranes during reproduction differ entirely from those described so far for other cells. PMID:5344151

    Time-dependent Ginzburg-Landau (TDGL) equations are considered for modeling a thin-film finite size superconductor placed under magnetic field. The problem then leads to the use of so-called natural boundary conditions. Computational domain is partitioned into subdomains and bond variables are used in obtaining the corresponding discrete system of equations. An efficient time-differencing method based on the Forward Euler method is developed. Finally, a variable strength magnetic field resulting in a vortex motion in Type II High {Tc} superconducting films is introduced. The authors tackled the problem using two different state-of-the-art parallel computing tools: BlockComm/Chameleon and PCN. They had access to two high-performance distributed memory supercomputers: the Intel iPSC/860 and IBM SP1. They also tested the codes using, as a parallel computing environment, a cluster of Sun Sparc workstations.

Durant le processus de polissage des verres optiques, le polissoir est un élément clé et a un impact direct sur les performances des composants optiques, non seulement il est utilisé comme support de grains abrasifs mais il doit posséder la fonction de transmission de la pression aux grains. La connaissance de ses propriétés, essentiellement mécanique, est impérative afin d'obtenir un état de surface optimal des composants optiques destinés à remplir des fonctions très précises dans des appareils optiques très performants.
Dans cette étude, nous avons constaté que les propriétés des polissoirs en polyuréthanne tel que la dureté, le module d'élasticité et la densité varient au cours du polissage. Ce changement a des effets sur l'état de surface de verre optique, causé par le changement microstructural de la surface du polissoir (distribution et dimensions des pores) et par conséquent sur la quantité des abrasifs (en oxyde de cérium) insérée dans les pores, ce qui influe sur la quantité de verre enlevée et sur l'état de surface du composant.
Sur la base des résultats obtenus, il a été prouvé que le polissoir subit des modifications très importantes ce qui influe considérablement sur son efficacité de polissage.

    Radio-induced degradation of DNA involves radical processes. A series of lesions among the major bases degradation products has been measured in isolated DNA exposed to gamma radiation in aerated aqueous solution. Degradation can be accounted for by the formation of hydroxyl radicals upon radiolysis of water (indirect effect). The four bases are degraded in high yield. Direct effect has been mimicked by photo-induced electron abstraction from the bases producing their radical cation. Quantification of the modified bases showed that guanine is the preferential target. This can be explained by its lower oxidation potential and charge transfer phenomena. La décomposition radio-induite de l'ADN fait intervenir des processus radicalaires. Une série de lésions choisies parmi les produits majeurs de dégradation des bases a été mesurée dans de l'ADN isolé exposé au rayonnement en solution aqueuse aérée. Les modifications sont alors dues aux radicaux hydroxyles produits par la radiolyse de l'eau (effet indirect) et les quatre bases sont efficacement dégradées. L'arrachement d'électrons aux bases par photosensibilisation pour produire leur radical cation, a été utilisé comme modèle de l'effet direct. La quantification des bases modifiées montre que la guanine est préférentiellement dégradée. Cette observation peut s'expliquer par le plus faible potentiel d'oxydation de cette base ainsi que par les phénomènes de transfert de charge vers les guanines.

    1998-02-01

    The subunit of the guinea pig fertilin (previously known as PH-30, an integral membrane protein involved in sperm-egg binding and fusion) is predicted to be a potential fusion protein. The structure of this putative fusion protein was analysed by molecular modeling and we have found a peptidic sequence of 17 residues (D83{-P99}) organized in helix that inserts obliquely in lipid phases. The effect of this synthesized peptide was studied on a model membrane by 31P NMR and light scattering. It appears to increase the size of lipid vesicles and induces structural modifications. We interpret these observations as a destabilization of the lipid organization by this peptide because of its tilted insertion in phospholipid layers. This destabilization could favor membrane fusion. La sous-unité α de la fertiline du cochon d'inde (précédemment appelée PH-30, une protéine membranaire impliquée dans la liaison et la fusion ovule-spermatozoïde) est prédite comme étant une protéine de fusion potentielle. Nous avons analysé la structure de cette protéine par modélisation moléculaire et nous avons trouvé une séquence peptidique de 17 résidus (D83 P99) organisée en hélice qui s'insère de façon oblique dans une phase lipidique. L'effet de ce peptide synthétique a été étudié sur membrane modèle par RMN du 31P et par diffusion de la lumière. Il provoque une augmentation de taille de vésicules lipidiques et induit des modifications structurales. Nous interprétons ces observations en termes de déstabilisation de l'organisation lipidique par ce peptide à cause de son insertion oblique dans la couche lipidique. Cette déstabilisation pourrait favoriser la fusion membranaire.

  16. Use of Data Comm by Flight Crew to Conduct Interval Management Operations to Parallel Dependent Runways

    NASA Technical Reports Server (NTRS)

    2011-01-01

    The Interval Management (IM) concept is being developed as a method to maintain or increase high traffic density airport arrival throughput while allowing aircraft to conduct near idle thrust descents. The Interval Management with Spacing to Parallel Dependent Runways (IMSPiDR1) experiment at NASA Langley Research Center used 24 commercial pilots to examine IM procedures to conduct parallel dependent runway arrival operations while maintaining safe but efficient intervals behind the preceding aircraft. The use of IM procedures during these operations requires a lengthy and complex clearance from Air Traffic Control (ATC) to the participating aircraft, thereby making the use of Controller Pilot Data Link Communications (CPDLC) highly desirable as the communication method. The use of CPDLC reduces the need for voice transmissions between controllers and flight crew, and enables automated transfer of IM clearance elements into flight management systems or other aircraft avionics. The result is reduced crew workload and an increase in the efficiency of crew procedures. This paper focuses on the subset of data collected related to the use of CPDLC for IM operations into a busy airport. Overall, the experiment and results were very successful, with the mean time under 43 seconds for the flight crew to load the clearance into the IM spacing tool, review the calculated speed, and respond to ATC. An overall mean rating of Moderately Agree was given when the crews were asked if the use of CPDLC was operationally acceptable as simulated in this experiment. Approximately half of the flight crew reported the use of CPDLC below 10,000 for IM operations was unacceptable, with 83% reporting below 5000 was unacceptable. Also described are proposed modifications to the IM operations that may reduce CPDLC Respond time to less than 30 seconds and should significantly reduce the complexity of crew procedures, as well as follow-on research issues for operational use of CPDLC during IM operations.

    NASA Astrophysics Data System (ADS)

    Ruellan, Arthur

    Atherosclerosis is a worldwide epidemic related to several factors including lifestyle and genetic predisposition. There are two main approaches to treating atherosclerosis: one that aims lowering levels of low-density lipoprotein (LDL) in the bloodstream to avoid or decrease genesis of atheroma plaques, and the other approach aims to remove atheroma plaques through surgical techniques such as by-pass surgery or stent implantation. As these two approaches are inadapted for outpatients or those who present hypercholesterolemia, it is urgent to develop new drugs and technologies to address these situations. A conventional weapon for lowering the LDL level from bloodstream is the plasmapheresis which it requires long daily hospitalization time and therefore impacts the quality of life of patients. Therefore, this thesis aims to present the application of superparamagnetic iron oxide nanoparticles (SPIONs) as vectors to decrease the levels of free-LDL in the bloodstream. Indeed we present the proof of concept of a potential new treatment for atherosclerosis using the functionalized SPIONs targeting LDL. We have evaluated the biocompatibility of those SPIONs through in vitro cytotoxicity and hemocompatibility tests. Our ability to move these SPIONs, uni-directionally, under a magnetic field, demonstrates the feasibility of using them in an ex-vivo blood circulation system, containing a magnetic trap to gather them once they have fastened to the LDL present in the blood. By ex vivo tests with hypercholesterolemic rabbit blood plasma, we have found that each interaction of SPIONs, at 0.5 mg/mL, decreases the concentration of LDL by at least 34%.

    Le débat autour des origines développementales de la capacité humaine à utiliser des outils de manière souple reste ouvert. Alors que l’approche dominante se focalise sur un changement qualitatif cognitif vers la fin de la première année, la théorie perception-action fournit des indices importants sur la manière dont les comportements exploratoires plus précoces des nourrissons jettent les bases pour l’émergence de cette capacité. En particulier, nous nous intéressons à la manière dont les tentatives des nourrissons de mettre en rapport les objets et les surfaces leur permettent d’apprendre comment les objets peuvent servir d’extension de la main et fournissent l’occasion d’exercer des actions qui seront recrutées plus tard pour l’utilisation d’outils. Dans ce contexte, nous discutons des études comportementales et cinématiques portant sur la manipulation d’objets, qui montrent que les nourrissons font interagir les objets et les surfaces avec discernement et que leur contrôle de la frappe (banging) augmente au cours de leur première année. En conclusion, une perspective perception-action suggère que l’utilisation d’outils émerge de manière plus continue au cours du développement que ce qui a été traditionnellement envisagé.

Il etait compose de professeurs de la Faculte de medecine et des sciences de la sante soit : Darel Hunting PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Leon Sanche PhD, directeur de recherche (departement de medecine nucleaire et radiobiologie), Richard Wagner PhD, membre du programme (departement de medecine nucleaire et radiobiologie) et Guylain Boissonneault PhD, membre exterieur au programme (departement de biochimie). Le 5-bromodeoxyuridine (BrdU), un analogue halogene de la thymidine reconnu depuis les annees 60 comme etant un excellent radiosensibilisateur. L'hypothese la plus repandue au sujet de l'effet radio sensibilisant du BrdU est qu'il augmente le nombre de cassures simple et double brin lorsqu'il est incorpore dans l'ADN de la cellule et expose aux radiations ionisantes. Toutefois, de nouvelles recherches semblent remettre en question les observations precedentes. Ces dernieres etudes ont confirme que le BrdU est un bon radiosensibilisateur, car il augmente les dommages radio-induits dans l'ADN. Mais, c'est en etant incorpore dans une region simple brin que le BrdU radiosensibilise l'ADN. Ces recherches ont egalement revele pour la premiere fois un nouveau type de dommages produits lors de l'irradiation de l'ADN contenant du BrdU : les dimeres interbrins. Le but de ces travaux de recherche est de determiner si la presence de bromodeoxyuridine dans l'ADN augmente l'induction de bris simple et / ou double brin chez les cellules irradiees en utilisant de nouvelles techniques plus sensibles et specifiques que celles utilisees auparavant. Pour ce faire, les essais cometes et la detection des foci H2AX phosphorylee pourraient permettre d'etablir les effets engendres par

    The monolithic image of radiation pathology, the physiopathological mechanisms of which are limited to the conventional concept of specific “target cell" with mitotic and apoptotic cell death, is changing owing to our increasing knowledge about intercellular communications. The cellular radiationbiology is currently enriched by the “humoral" radiationbiology with its concept of “target network" including cells and intercellular messengers. The radiation-induced disorders observed in these networks take shape in the inflammatory reaction, which is largely involved, in the physiopathological development of the acute radiation syndrome. These concepts of a perpetual cascade of cytokines, leading to radiation-induced late effects with no biological latent period, are especially illustrated by the radiation-induced pneumonitis and pulmonary fibrosis. L'image monolithique de la radiopathologie dont les mécanismes physiopathologiques sont réduits aux concepts classiques de “cellule cible" spécifique avec mort cellulaire mitotique et apoptotique, se modifie grâce à l'accroissement de nos connaissances sur les communications intercellulaires. La radiobiologie cellulaire s'enrichit aujourd'hui de la radiobiologie “humorale" avec son concept de “réseau cible" tant au niveau des cellules que des messagers intercellulaires. Les désordres radio-induits observés au niveau de ces réseaux se concrétisent dans la réaction inflammatoire qui est fortement impliquée dans l'évolution physiopathologique du syndrome aigu d'irradiation. Ces concepts d'une cascade perpétuelle de cytokines, sans période de latence biologique et qui amènent aux effets tardifs radio-induits, sont particulièrement illustrés dans la pneumonie et la fibrose pulmonaire radio-induites.

    Summary L’association brûlure et épilepsie est une constatation fréquente au Maroc. Ces brûlures, souvent itératives, touchent le plus souvent des femmes jeunes de milieu rural. L’accident survient habituellement au domicile, le plus souvent dans la cuisine à la suite d’une chute sur un moyen de cuisson posé au sol. Elles peuvent être inaugurales de la maladie mais surviennent plus souvent chez des patients connus mais au traitement mal suivi. Les conséquences de ces brûlures, toujours profondes, sont souvent dramatiques en termes de séquelles, chez des patients ayant déjà une insertion sociale rendue difficile par l’épilepsie. La prise en charge doit être multidisciplinaire et concerner à la fois la brûlures et l’épilepsie. Des mesures de prévention simples, visant à équilibrer l’épilepsie et éviter au patient de se trouver seul à proximité d’une source de chaleur, doivent être mises en place. PMID:27252613

    In this article on the cultural context of children's learning processes among the indigenous peoples of tropical South America, the author aims to show how in these cultures the human body offers a language and a mechanism central to the process of production, elaboraton and transmission of knowledge, skills and emotions. She works from the assumption that the construction of a child's identity is a process which takes place in the body, creating a synthesis of social, cosmological, psychological, emotional and cognitive meanings. In constructing an ethnography of the Akwe~-Xavante and Akwe~-Xerente peoples of central Brazil, the author refers to recent anthropological debates on the cosmology and outlook of the indigenous peoples of this region, as well as to the literature of the new discipline known as "anthropology of the child".

  9. Commande optimale minimisant la consommation d'energie d'un drone utilise comme relai de communication

    NASA Astrophysics Data System (ADS)

    Mechirgui, Monia

    The purpose of this project is to implement an optimal control regulator, particularly the linear quadratic regulator in order to control the position of an unmanned aerial vehicle known as a quadrotor. This type of UAV has a symmetrical and simple structure. Thus, its control is relatively easy compared to conventional helicopters. Optimal control can be proven to be an ideal controller to reconcile between the tracking performance and energy consumption. In practice, the linearity requirements are not met, but some elaborations of the linear quadratic regulator have been used in many nonlinear applications with good results. The linear quadratic controller used in this thesis is presented in two forms: simple and adapted to the state of charge of the battery. Based on the traditional structure of the linear quadratic regulator, we introduced a new criterion which relies on the state of charge of the battery, in order to optimize energy consumption. This command is intended to be used to monitor and maintain the desired trajectory during several maneuvers while minimizing energy consumption. Both simple and adapted, linear quadratic controller are implemented in Simulink in discrete time. The model simulates the dynamics and control of a quadrotor. Performance and stability of the system are analyzed with several tests, from the simply hover to the complex trajectories in closed loop.

  10. La convergence du flux de vapeur d'eau et son potentiel comme variable hydrologique de surface

    NASA Astrophysics Data System (ADS)

    Cardin-Ouellette, Sabrina

    Hydrology is often oriented on the terrestrial branch of the hydrologic cycle. In a watershed, the amount of water vapor can change due to atmospheric transport. The horizontal convergence of the moisture flux (C) constitutes the net input of water vapor in a given region. For long time periods and on a watershed's spatial scale, the horizontal convergence of the moisture flux should equal the water runoff of the watershed region. Keeping track of C should be an interesting way of increasing the efficiency of hydrological models. The global objective of this project is to quantify the hydrological cycle in the Canadian Regional Climate Model (CRCM) to evaluate if the horizontal convergence of the moisture flux can be used as an informative variable in hydrological models. The CRCM is useful to model complex hydrologic phenomena at regional scale and calculates components of the cycle that are difficult to obtain in the field. The results show that convergence is equal to the runoff on the climatic temporal scale. The temporal annual series also shows large correlation between the runoff and the convergence (r >0.8). On the monthly time scale, the relation is not as obvious because the atmospheric and terrestrial reservoirs also hold transiting water. During winter, the monthly convergence in the Nordic watersheds is approximately equal to the variation of the snow cover. The error in the simulated hydrological balance varies between 0 and 10% on the climatic time scale. This is much less than the error obtained by similar studies using reanalyses. At this scale, the term of error is related to the semi-Lagrangian computational scheme and possibly to the correction of the hydrological balance integrated in the MRCC. Increasing error on the monthly (0 to 30%) and daily (0 to 100%) time scales is due to a 6 hours temporal gap between the averaged variables and instantaneous variables in the recording scheme of the MRCC. Keywords: Hydrologic cycle, Moisture flux convergence, Canadian regional climate model.

    In the above communication, we have investigated in details the possibility of observing a large negative lateral Goos-Hanchen (GH) shift from p-polarized light at long wavelength incident onto a bare metal surface, at angles close to grazing incidence. The shift could be up to a few wavelength (e.g. ∼20 μm at a wavelength of 3390 nm onto silver) and the possible presence of a "pseudo Brewster angle" will not hinder the observability of such an effect. This effect has since been verified experimentally via reflection of IR light from a gold surface [1].

    La polyarthrite rhumatoïde est une maladie systémique inflammatoire caractérisée par une destruction des synoviales articulaires et des lésions systémiques extra articulaires. Les nodules pulmonaires font partie de ces dernières. Leur évolution peut aboutir à un pneumothorax spontané. Nous rapportons le cas d'un adulte jeune au long passé de polyarthrite rhumatoïde qui a présenté deux épisodes de pneumothorax spontané. Il était admis dans notre service, en urgence, pour un pneumothorax droit spontané et massif sur terrain de polyarthrite rhumatoïde au stade de déformation. Il était sous méthotrexate. La radiographie standard du thorax et la tomodensitométrie montraient un décollement pleural complet droit, des nodules et des images excavées sur les deux champs pulmonaires. Il a bénéficié d'un drainage thoracique aspiratif permettant une bonne ré-expansion pulmonaire. Le pneumothorax spontané constitue une manifestation rare des lésions pulmonaire de la polyarthrite rhumatoïde.

    In underground flow tracing studies, the estimation of the nature and the importance of interactions undergone by the substance used very often constitutes an obstacle to good modeling of mass-transfer processes in solution. We propose a method to quantify these phenomena by the use of lanthanides as tracers. For this study, we set up an analytical methodology adapted to routine measurements. The quality of five lanthanides as indicators has been examined. We have demonstrated the formation, by substitution, of a carbonate complex which is extremely stable in the natural environment. The field experiments carried out demonstrated the efficiency of those tracers and confirmed their great stability. Tracer recovery graphs show that, in accord with our hypothesis, convection and dispersion are identical for all the lanthanide elements. Moreover, we have established a direct relation between their fixing rate on earth materials and the value of their stability constants. Thus, we demonstrate the possibility of correlative multitracing, with known and quantifiable interelement relations.

    Carbons derived from the pyrolysis of polyparaphenylene at 700 circC under various conditions (hydrogen gas, argon gas and vacuum) were characterized by X-ray diffraction, infrared and Raman spectroscopies. The affinity of these materials for lithium was tested by electrochemical measurements. The reversible capacity depends on the pyrolysis atmosphere. The best performances were obtained with carbons of pyrolyzed PPP under hydrogen gas (x=760mAh/g). Des matériaux carbonés, dérivés de la pyrolyse du polyparaphénylène à 700 circC sous différentes atmosphères (hydrogène, argon et vide), ont été caractérisés par diffraction des rayons X, spectroscopies Raman et infra-rouge. L'affinité de ces matériaux pour le lithium a été testée par électrochimie. La capacité réversible dépend des conditions de pyrolyse, les meilleures performances étant obtenues avec le PPP traité sous hydrogène (x=760mAh/g).

    The present study characterizes the effluents of the 'Maroc Phosphore' factories III and IV (of Jorf Lasfar coastal zone). The results show that the effluent (Cs/l) is very acid, very phosphate-rich, high in suspended matter and calcium-rich. Hydrological parameters indicate an important content of phosphates, especially in the stations located in the South of Cs/l. Tissues of mussel Mytilus galloprovincialis from the Jorf Lasfar zone present high concentrations of Cd and Cu.

    NMR study of membrane biomolecules comes up against a poor solubility in classical solvents. A strategy was elaborated to obtain structural information of peptides in non deuterated phospholipids vesicles. It is based on isotopic (HSQC-NOESY) and homonuclear selective filters, both using a fine water suppression. The method is illustrated with the substance P, a 11-residue membrane neuropeptide. L'étude par RMN des biomolécules membranaires est délicate en raison de leur faible solubilité. Une stratégie d'étude a été élaborée pour obtenir des informations structurales de peptides dans un environnement de vésicules de phospholipides non deutérés. Elle repose sur des filtres isotopiques de type HSQC-NOESY et des filtres homonucléaires avec impulsion sélective, avec une suppression fine de l'eau. Un exemple est donné sur un neuropeptide membranaire de 11 résidus : la substance P.

    150mmHg, the permeate flux hardly changes, which confirms that once concentration polarization is established, the system membrane-polarization layer ceases to behave as a porous medium even with increased resistance. These data can explain the permeate increase observed when pressure and flow pulsations at 1Hz are superimposed on the retentate. La plasmaphérèse par membrane consiste à filtrer le plasma au travers d'une membrane microporeuse sous l'action de la pression transmembranaire. Comme toutes filtrations tangentielles, le flux de filtration augmente linéairement aux faibles pressions transmembranaires, puis atteint un plateau aux fortes pressions à cause du phénomène de polarisation de concentration et du colmatage de la membrane. La polarisation de concentration est due à la formation d'une couche fortement concentrée en soluté au voisinage de la membrane. Le temps de formation de cette couche est rapide, généralement inférieur à une minute. En microfiltration du sang, cette couche est constituée des globules qui forment une seconde membrane réversible qui limite le flux de filtration. Dans ce régime, le flux de perméat devient indépendant de la pression transmembranaire et dépend principalement du taux de cisaillement. Nous avons entrepris une étude de la réponse transitoire d'une membrane à des échelons de pression transmembranaire afin de comprendre la cinétique d'établissement de ces phénomènes. Lorsque l'on passe brusquement d'un régime non polarisé à celui polarisé, le flux de filtration croît jusqu'à un pic en 0,4 à 0,6s dépassant la valeur du plateau de 60 à 80%, puis il revient à sa valeur d'équilibre correspondant au régime de polarisation de concentration en 3 à 4s. Les données expérimentales montrent que la membrane garde une perméabilité originale pendant seulement 0,5s lors d'un changement brusque de pression et que la couche de polarisation de concentration met environ 3 à 4s à s'établir.

    Gamma irradiation leads to an increased production of interleukin- (IL)-6 and IL-8 by human endothelial cells. In order to regulate the radio-induced production of these pro-inflammatory cytokines, we used the immunoregulatory cytokines IL-4 and IL-10. These agents were added either before or after a 10 Gy-irradiation. Our results show that it is possible to decrease the radio-induced production of IL-6 and IL-8 with the use of IL-4 and IL-10. Differences in the intensity of the response have been observed according to the time of treatment. The anti-inflammatory potential of both IL-4 and IL-10 was more pronounced when added after irradiation. Après irradiation gamma, des cellules endothéliales humaines ont une production accrue des interleukines (IL-) -6 et -8. Dans le but de réguler la production de ces cytokines pro-inflammatoires, nous avons utilisé des cytokines dites anti-inflammatoires, l'IL-4 et l'IL-10. Ces agents ont été ajoutés soit avant soit après une irradiation de 10Gy. Nos résultats montrent qu'il est possible de diminuer les productions radio-induites d'IL-6 et d'IL-8 par l'IL-4 et l'IL-10. Des différences dans l'intensité de la réponse ont toutefois été observées selon que l'IL-4 ou l'IL-10 ont été ajoutées avant ou après irradiation; leur efficacité anti-inflammatoire étant plus marquée lorsque les cytokines sont ajoutées après l'irradiation.

    Betts, Harley D.; DeRose, Ronald C.

    This paper describes the use of Digital Elevation Models (DEMs), constructed from sequential aerial photographs, as a tool for measuring gully erosion in a geomorphologically unstable environment. The technique is applied to a case study that examines erosion in 26 gullies in two study areas in the upper Waipaoa catchment, eastern North Island, New Zealand. Changes over two consecutive time periods, ranging in length from 14.0 years to 33.2 years, were studied at each site, drawing on available historical aerial photography. Several key aspects of the method used are described and discussed in detail, and recommendations are made for future application of DEMs for assessment of landscape change. DEM-measured gully degradation rates are directly proportional to the square root of the gully area.From this relationship it should be possible to rapidly estimate gully erosion at a catchment scale on the basis of gully areas alone. DEM-based measurement techniques, together with appropriate consideration for the sensitivity of the method, have significant cost and efficiency advantages over manual approaches to erosion measurements.

    In radiation treatment, a sufficiently high radiation dose must be delivered to the tissue volumes containing the tumor cells while the lowest possible dose should be deposited in surrounding healthy tissue. We developed an original approach that is fast and easy to implement for the early assessment of the efficiency of radiation sensitizers and protectors. In addition, we characterized a new femtosecond laser pulse irradiation technique. We are able to deposit a considerable dose with a very high dose rate inside a well-controlled macroscopic volume without deposition of energy in front or behind the target volume. The radioprotective efficiency was measured by irradiation of the Fricke solution incorporating a compound under study and measuring the corresponding production of ferric ions G(Fe3+). The production of ferric ions is most sensitive to the radical species produced in the radiolysis of water. We studied experimentally and simulated with a full Monte-Carlo computer code the radiation-induced chemistry of Fricke/cystamine solutions. Results clearly indicate that the protective effect of cystamine originates from its radical-capturing ability, which allows this compound to compete with the ferrous ions for the various free radicals - especially ·OH radicals and H· atoms - formed during irradiation of the surrounding water. The sensitizing capacity of radiation sensitizers was measured by irradiation of a polyacrylamide gel (PAG) dosimeter incorporating a compound under study and measuring the corresponding increase in the gradient between spin-spin relaxation rate (R2) and absorbed dose. We measured an irradiation energy-dependent increase in R 2-dose sensitivity for halogenated compounds or a decrease for radioprotectors. Finally, we studied a novel laser irradiation method called "filamentation". We showed that this phenomenon results in an unprecedented deposition of energy and the dose rate thus achieved exceeds by orders of magnitude values previously reported for the most intense clinical radiotherapy systems. Moreover, the length of the dose-free entrance region was adjusted by selecting the duration of femtosecond laser pulses. In addition, we provided evidence that the biological damage caused by this irradiation was similar to other ionizing radiation sources. Keywords: Radiotherapy, radiosensitization, radioprotection, laser, filamentation, dosimetry.

    Scientific communication (SciComm) skills are indispensable for success in biomedical research, but many trainees may not have fully considered the necessity of regular writing and speaking for research career progression. Our purpose was to investigate the relationship between SciComm skill acquisition and research trainees’ intentions to remain in research careers. We used social cognitive career theory (SCCT) to test a model of the relationship of SciComm skills to SciComm-related cognitive variables in explaining career intentions. A sample of 510 graduate students and postdoctoral fellows at major academic health science centers in the Texas Medical Center, Houston, Texas, were surveyed online. Results suggested that interest in performing SciComm tasks, SciComm outcome expectations (SCOEs), and SciComm productivity predicted intention to remain in a research career, while SciComm self-efficacy did not directly predict career intention. SCOEs also predicted interest in performing SciComm tasks. As in other SCCT studies, SciComm self-efficacy predicted SCOEs. We conclude that social cognitive factors of SciComm skill acquisition and SciComm productivity significantly predict biomedical trainees’ intentions to pursue research careers whether within or outside academia. While further studies are needed, these findings may lead to evidence-based interventions to help trainees remain in their chosen career paths. PMID:26628562

    commissureless and roundabout lead to complementary mutant phenotypes in which either too few or too many axons cross the midline. The robo;comm double-mutant phenotype is identical to robo alone, suggesting that in the absence of robo, comm is no longer required. Comm is expressed on midline cells; Robo is expressed in a dynamic fashion on growth cones and appears to function as an axon guidance receptor. robo function is dosage-sensitive. Overexpression of comm is also dosage-sensitive and leads to a phenotype identical to robo loss-of-function. Comm controls Robo expression; increasing Comm leads to a reduction of Robo protein. The levels of Comm and Robo appear to be tightly regulated to assure that only certain growth cones cross the midline and that those growth cones that do cross never do so again.

    The Current Opioid Misuse Measure (COMM) has demonstrated promising psychometric properties among pain clinic and primary care patients. Given the high prevalence of the nonmedical use of prescription opioids among substance use disorder patients, the COMM may also be useful in substance use disorder treatment settings. The purpose of this study was to assess the factor structure and validity of the COMM in a sample of substance use disorder patients. Participants (n = 351) were recruited from a large residential substance use disorder treatment center and completed the COMM and several questionnaires assessing various substance use and health functioning characteristics. Factor analyses yield a two-factor solution; however, each of the items in the second factor cross-loaded onto the first factor and just one factor was retained. To provide support for this new 11-item COMM, we found that higher scores on this COMM were associated with greater drug use severity, greater endorsement of positive, negative, and pain relief outcome expectancies related to opioid use, increased pain intensity, and decreased physical and mental health functioning. These findings provide initial support for the psychometric properties of this version of the COMM adapted for substance use disorder treatment settings. Given its promising psychometric properties, the 11 items of the COMM to evaluate the nonmedical use of prescription opioids has potential utility among substance use disorder patients. The COMM could be used to examine nonmedical use over the course of treatment and to aid treatment planning. It could also be used in research as an outcome measure. PMID:25800105

    A human-in-the-loop simulation was conducted to investigate the operational feasibility, technical requirements, and potential improvement in airspace efficiency of adding a Multi-Sector Planner position. A subset of the data from that simulation is analyzed here to determine the impact, if any, of ground-ground data communication (Data Comm) on verbal communication and coordination for multi-sector air traffic management. The results suggest that the use of Data Comm significantly decreases the duration of individual verbal communications. The results also suggest that the use of Data Comm, as instantiated in the current simulation, does not obviate the need for accompanying voice calls.

  4. Improvement of turkey breast meat quality and cooked gel functionality using hot-boning, quarter sectioning, crust-freeze-air-chilling and cold-batter-mincing technologies.

    PubMed

    Lee, H C; Erasmus, M A; Swanson, J C; Hong, H G; Kang, I

    2016-01-01

    The effect of rapid carcass chilling on breast meat quality was evaluated using commercial (COMM) and random-bred (RB) turkeys. Immediately after slaughter, 48 turkeys from COMM or RB line were randomly subjected to one of four chilling methods: 1) water-immersion chilling (WIC) of the carcasses at 0°C ice slurry, 2) WIC after temperature abuse (TA) of the carcasses at 40°C for 30 min (TA-WIC), 3) hot-boning, quarter sectioning, and crust-freeze-air-chilling (HB-(1)/4CFAC) of breast fillets at -12°C, and 4) HB-(1)/4CFAC of fillets after TA of carcasses (TA-HB-(1)/4CFAC). The TA increased carcass and fillet temperatures by ∼1.3 and ∼4.1°C, respectively, regardless of turkey line, whereas HB-(1)/4CFAC of fillets required 28 and 33% of carcass chilling time for COMM and RB, respectively. During chilling, COMM breast pH rapidly reduced from 6.04 to 5.82, resulting in a significantly lower pH than RB after chilling (P < 0.05), whereas COMM R-value sharply increased from 1.17 to 1.43, causing no difference from RB (P > 0.05). Significantly higher L* value and cooking yield (P < 0.05) were seen in the samples of TA and WIC than those of no TA and HB-(1)/4CFAC, respectively, with no difference observed between COMM and RB fillets (P > 0.05). Higher values of hardness, gumminess, and chewiness were found for RB, no TA, and HB-(1)/4CFAC gels than COMM, TA, and WIC, respectively. These results generally indicated that protein quality and textural properties of turkey fillets were improved, regardless of strains or temperature abuse, using HB-(1)/4CFAC technology.

  5. The Impact of Data Communications Messages in the Terminal Area on Flight Crew Workload and Eye Scanning

    2010-01-01

    This paper, to accompany a discussion panel, describes a collaborative FAA and NASA research study to determine the effect Data Communications (Data Comm) messages have on flight crew workload and eye scanning behavior in busy terminal area operations. In the Next Generation Air Transportation System Concept of Operations, for the period 2017-2022, the FAA envisions Data Comm between controllers and the flight crew to become the primary means of communicating non-time critical information. Four research conditions were defined that span current day to future equipage levels (Voice with Paper map, Data Comm with Paper map, Data Comm with Moving Map Display with ownship position displayed, Data Comm with Moving Map, ownship and taxi route displayed), and were used to create arrival and departure scenarios at Boston Logan Airport. Preliminary results for workload, situation awareness, and pilot head-up time are presented here. Questionnaire data indicated that pilot acceptability, workload, and situation awareness ratings were favorable for all of the conditions tested. Pilots did indicate that there were times during final approach and landing when they would prefer not to hear the message chime, and would not be able to make a quick response due to high priority tasks in the cockpit.

  6. Selection of optimal oligonucleotide probes for microarrays usingmultiple criteria, global alignment and parameter estimation.

    SciTech Connect

    Li, Xingyuan; He, Zhili; Zhou, Jizhong

    2005-10-30

    The oligonucleotide specificity for microarray hybridizationcan be predicted by its sequence identity to non-targets, continuousstretch to non-targets, and/or binding free energy to non-targets. Mostcurrently available programs only use one or two of these criteria, whichmay choose 'false' specific oligonucleotides or miss 'true' optimalprobes in a considerable proportion. We have developed a software tool,called CommOligo using new algorithms and all three criteria forselection of optimal oligonucleotide probes. A series of filters,including sequence identity, free energy, continuous stretch, GC content,self-annealing, distance to the 3'-untranslated region (3'-UTR) andmelting temperature (Tm), are used to check each possibleoligonucleotide. A sequence identity is calculated based on gapped globalalignments. A traversal algorithm is used to generate alignments for freeenergy calculation. The optimal Tm interval is determined based on probecandidates that have passed all other filters. Final probes are pickedusing a combination of user-configurable piece-wise linear functions andan iterative process. The thresholds for identity, stretch and freeenergy filters are automatically determined from experimental data by anaccessory software tool, CommOligo_PE (CommOligo Parameter Estimator).The program was used to design probes for both whole-genome and highlyhomologous sequence data. CommOligo and CommOligo_PE are freely availableto academic users upon request.

  7. Simulations of transferred NOE in a ternary peptide-receptor-lipid complex

    NASA Astrophysics Data System (ADS)

    Czaplicki, J.; Milon, A.

    1998-02-01

    Analyses of neuropeptides interacting with their receptors in presence of lipid membranes require the use of spin systems including several molecules (peptide, membrane, receptor) in at least three states (free, membrane-bound and receptor-bound ligand). Moreover, the exchange rates can be arbitrary. We have developed a program, based on the generalized relaxation matrix method, capable of treating all direct and indirect spin interactions. The program allows a simulation of homonuclear NOE and ROE experiments in case of arbitrary exchange rates, for systems with internal mobility and groups of equivalent spins. We present here some simulations for a system of three states, such as the free, membrane-bound and receptor-bound ligand, aiming at defining more precisely the limits of the transferred NOE experiments for the determination of the receptor-bound conformation of a neuropeptide. Dans le cas d'étude des interactions entre les neuropeptides et leurs récepteurs membranaires on travaille avec un système de plusieurs spins, dans au moins trois états (libre, intermédiaire et lié), qui peuvent appartenir à des molécules différentes (ligand, membrane et récepteur). De plus, les constantes d'échange parmi ces états sont arbitraires. Nous avons développé un logiciel, basé sur la méthode des matrices de relaxation, qui décrit tous les effets d'interactions (directes et indirectes) entre les spins. Ce logiciel permet de simuler les expériences homonucléaires NOE et ROE dans les cas d'échange arbitraire, pour les systèmes possédant une mobilité interne et des groupes de spins équivalents. Nous présentons le résultat de simulations obtenues dans un système à trois états du type peptide libre, peptide lié au lipide, peptide lié au récepteur, dont le but est de préciser les limites d'utilisation des NOEs transférés en vue de déterminer la conformation de neuropeptides liés à leur récepteur.

    CommAspen is a new agent-based model for simulating the interdependent effects of market decisions and disruptions in the telecommunications infrastructure on other critical infrastructures in the U.S. economy such as banking and finance, and electric power. CommAspen extends and modifies the capabilities of Aspen-EE, an agent-based model previously developed by Sandia National Laboratories to analyze the interdependencies between the electric power system and other critical infrastructures. CommAspen has been tested on a series of scenarios in which the communications network has been disrupted, due to congestion and outages. Analysis of the scenario results indicates that communications networks simulated by the model behave as their counterparts do in the real world. Results also show that the model could be used to analyze the economic impact of communications congestion and outages.

    2012-01-01

    The ERKN methods proposed by H. Yang et al. [Comput. Phys. Comm. 180 (2009) 1777] are an important improvement of J.M. Franco's ARKN methods for perturbed oscillators [J.M. Franco, Comput. Phys. Comm. 147 (2002) 770]. This paper focuses on the symmetry and symplecticity conditions for ERKN methods solving oscillatory Hamiltonian systems. Two examples of symmetric and symplectic ERKN (SSERKN) methods of orders two and four respectively are constructed. The phase and stability properties of the new methods are analyzed. The results of numerical experiments show the robustness and competence of the SSERKN methods compared with some well-known methods in the literature.

  18. Denitrification potential and its correlation to physico-chemical and biological characteristics of saline wetland soils in semi-arid regions.

    PubMed

    Yu, Huibin; Song, Yonghui; Xi, Beidou; Du, Erdeng; He, Xiaosong; Tu, Xiang

    2012-11-01

    Denitrification is an important pathway of NO(3)(-) removal depending on wetland soil characteristics. Most studies on denitrification have been conducted in the freshwater wetlands and coastal marshes, but little information is available on how soil and environmental factors affect denitrification of saline wetlands in semi-arid regions. We conducted a correlative study on denitrification potential in relation to the physico-chemical and biological characteristics. Composite soil samples of different depths were collected from different halophyte communities along a saline-impact gradient around Wuliangsuhai Lake, i.e. Comm. Salicornia europaea (CSE), Comm. Suaeda glauca (CSG), Comm. Kalidium foliatum (CKF) and Comm. Sophora alopecuroides (CSA). The CSA soil profile showed the fastest denitrification kinetics and tended to yield the largest amount of N(2)O, followed by the CKF, CSG and CSE. The mean of potential denitrification rates was the highest across all depths of the CSA soil profile, followed by the CKF, CSG, and CSE. Principal component analysis indicated that exchangeable sodium percentage was a key factor to denitrification potential, apart from organic carbon, nitrate and denitrifying bacteria. The results could have significant implication in integrated assessment and management of salined wetlands for treating nutrient-rich return water from farmland, industrial wastewater and domestic sewage in the diverted trunk drain used for the lakeshore restoration.

  5. Inhibitory mechanism of the nucleus of the solitary tract involved in the control of cardiovascular, dipsogenic, hormonal, and renal responses to hyperosmolality.

    2013-04-01

    The nucleus of the solitary tract (NTS) is the primary site of visceral afferents to the central nervous system. In the present study, we investigated the effects of lesions in the commissural portion of the NTS (commNTS) on the activity of vasopressinergic neurons in the hypothalamic paraventricular (PVN) and supraoptic (SON) nuclei, plasma vasopressin, arterial pressure, water intake, and sodium excretion in rats with plasma hyperosmolality produced by intragastric 2 M NaCl (2 ml/rat). Male Holtzman rats with 15-20 days of sham or electrolytic lesion (1 mA; 10 s) of the commNTS were used. CommNTS lesions enhanced a 2 M NaCl intragastrically induced increase in the number of vasopressinergic neurons expressing c-Fos in the PVN (28 ± 1, vs. sham: 22 ± 2 c-Fos/AVP cells) and SON (26 ± 4, vs. sham: 11 ± 1 c-Fos/AVP cells), plasma vasopressin levels (21 ± 8, vs. sham: 6.6 ± 1.3 pg/ml), pressor responses (25 ± 7 mmHg, vs. sham: 7 ± 2 mmHg), water intake (17.5 ± 0.8, vs. sham: 11.2 ± 1.8 ml/2 h), and natriuresis (4.9 ± 0.8, vs. sham: 1.4 ± 0.3 meq/1 h). The pretreatment with vasopressin antagonist abolished the pressor response to intragastric 2 M NaCl in commNTS-lesioned rats (8 ± 2.4 mmHg at 10 min), suggesting that this response is dependent on vasopressin secretion. The results suggest that inhibitory mechanisms dependent on commNTS act to limit or counterbalance behavioral, hormonal, cardiovascular, and renal responses to an acute increase in plasma osmolality.

  6. Visual Odometry for Autonomous Deep-Space Navigation

    NASA Technical Reports Server (NTRS)

    Robinson, Shane; Pedrotty, Sam

    2016-01-01

    Visual Odometry fills two critical needs shared by all future exploration architectures considered by NASA: Autonomous Rendezvous and Docking (AR&D), and autonomous navigation during loss of comm. To do this, a camera is combined with cutting-edge algorithms (called Visual Odometry) into a unit that provides accurate relative pose between the camera and the object in the imagery. Recent simulation analyses have demonstrated the ability of this new technology to reliably, accurately, and quickly compute a relative pose. This project advances this technology by both preparing the system to process flight imagery and creating an activity to capture said imagery. This technology can provide a pioneering optical navigation platform capable of supporting a wide variety of future missions scenarios: deep space rendezvous, asteroid exploration, loss-of-comm.

    Stephens, Donald R.

    2015-01-01

    CommLargo, Inc., has developed a scintillation-hardened Global Positioning System (GPS) receiver that improves reliability for low-orbit missions and complies with NASA's Space Telecommunications Radio System (STRS) architecture standards. A software-defined radio (SDR) implementation allows a single hardware element to function as either a conventional radio or as a GPS receiver, providing backup and redundancy for platforms such as the International Space Station (ISS) and high-value remote sensing platforms. The innovation's flexible SDR implementation reduces cost, weight, and power requirements. Scintillation hardening improves mission reliability and variability. In Phase I, CommLargo refactored an open-source GPS software package with Kalman filter-based tracking loops to improve performance during scintillation and also demonstrated improved navigation during a geomagnetic storm. In Phase II, the company generated a new field-programmable gate array (FPGA)-based GPS waveform to demonstrate on NASA's Space Communication and Navigation (SCaN) test bed.

    The Smoothed Particle Mesh Ewald method [U. Essmann, L. Perera, M.L. Berkowtz, T. Darden, H. Lee, L.G. Pedersen, J. Chem. Phys. 103 (1995) 8577] for calculating long ranged forces in molecular simulation has been adapted for the parallel molecular dynamics code DL_POLY_3 [I.T. Todorov, W. Smith, Philos. Trans. Roy. Soc. London 362 (2004) 1835], making use of a novel 3D Fast Fourier Transform (DAFT) [I.J. Bush, The Daresbury Advanced Fourier transform, Daresbury Laboratory, 1999] that perfectly matches the Domain Decomposition (DD) parallelisation strategy [W. Smith, Comput. Phys. Comm. 62 (1991) 229; M.R.S. Pinches, D. Tildesley, W. Smith, Mol. Sim. 6 (1991) 51; D. Rapaport, Comput. Phys. Comm. 62 (1991) 217] of the DL_POLY_3 code. In this article we describe software adaptations undertaken to import this functionality and provide a review of its performance.

  11. Effect of cropping systems on adsorption of metals by soils: I. Single-metal adsorption

    Basta, N.T.; Tabatabai, M.A. )

    1992-02-01

    The effect of long-term cropping systems on adsorption of metals was studied for soils obtained from two sites, Clarion-Webster Research Center (CWRC site) at Kanawha and Galva-Primghar Research Center (GPRC site) at Sutherland, under long-term rotation experiments in Iowa. Each experiment consisted of three cropping systems: continuous corn (CCCC), corn-soybean-corn-soybean (CSCS), and corn-oats-meadow-meadow (COMM), and treated with (+N) and without (0 N) ammoniacal fertilizer. In general, CSCS and COMM cropping systems did not significantly affect the metal adsorption maxima of soils obtained from both sites. Cadmium, Cu, and Pb adsorption were significantly correlated with pH and percentage base saturation for soils from both sites.

  12. Singular Harmonic Maps and Applications to General Relativity

    NASA Astrophysics Data System (ADS)

    Nguyen, Luc

    2011-01-01

    The study of axially symmetric stationary multi-black-hole configurations and the force between co-axially rotating black holes involves, as a first step, an analysis on the "boundary regularity" of the so-called reduced singular harmonic maps. We carry out this analysis by considering those harmonic maps as solutions to some homogeneous divergence systems of partial differential equations with singular coefficients. Our results extend previous works by Weinstein (Comm Pure Appl Math 43:903-948, 1990; Comm Pure Appl Math 45:1183-1203, 1992) and by Li and Tian (Manu Math 73(1):83-89, 1991; Commun Math Phys 149:1-30, 1992; Differential geometry: PDE on manifolds, vol 54, pp. 317-326, 1993). This paper is based on the Ph.D. thesis of the author (Singular harmonic maps into hyperbolic spaces and applications to general relativity, PhD thesis, The State University of New Jersey, Rutgers, 2009).

    Background Internet education is increasingly provided to health professionals, but little is known about the most effective strategies for delivering the content. The purpose of this study is to compare four strategies for delivering an Internet-based (e-) curriculum on clinicians' knowledge (K), confidence (CONF), and communication (COMM) about herbs and other dietary supplements (HDS). Methods This national randomized 2 × 2 factorial trial included physicians, pharmacists, nurses, nutritionists and trainees in these fields. Participants were randomly assigned to one of four curriculum delivery strategies for 40 brief modules about HDS: a) delivering four (4) modules weekly over ten (10) weeks by email (drip-push); b) modules accessible on web site with 4 reminders weekly for 10 weeks (drip-pull); c) 40 modules delivered within 4 days by email (bolus-push); and d) 40 modules available on the Internet with one email informing participants of availability (bolus-pull). Results Of the 1,267 enrollees, 25% were male; the average age was 40 years. The completion rate was 62%, without significant differences between delivery groups. There were statistically significant improvements in K, CONF and COMM scores after the course (P<0.001 for all), although the difference in COMM was small. There were no significant differences in any of the three outcomes by delivery strategy, but outcomes were better for those who paid for continuing education credit. Conclusion All delivery strategies tested similarly improved K, CONF, COMM scores about HDS. Educators can use the strategy that is most convenient without diminishing effectiveness. Additional curricula may be necessary to make substantial changes in clinicians' communication practices. PMID:16405734

    Background Community-based behavioral interventions are needed to reduce the burden of childhood obesity. Purpose This study evaluated the impact of a multi-level promotora-based (Community Health Advisor) intervention to promote healthy eating and physical activity (PA) and prevent excess weight gain among Latino children. Methods Thirteen elementary schools were randomized to one of four intervention conditions: individual and family level (Fam-only), school and community level (Comm-only), combined Fam+Comm intervention, or a measurement-only condition. Participants were 808 Latino parents and their children enrolled in kindergarten through 2nd grade. Measures included parent and child BMI and a self-administered parent survey that assessed several parent and child behaviors. Results There were no intervention effects on children's BMI z-score. The Fam-only and Fam+Comm interventions changed several obesity-related child behaviors and these were mediated by changes in parenting variables. Discussion A promotora-based behavioral intervention was efficacious at changing parental factors and child obesity-related health behaviors. PMID:22215470

    Impulsivity and sensation seeking have been associated with substance use disorders, including opioid use disorders. This pilot study sought to examine whether impulsivity and sensation seeking, as measured by the Barratt Impulsiveness Scale (BIS) and Sensation Seeking Scale (SSS), were associated with opioid analgesic misuse risk in chronic, low-back pain patients prescribed opioid analgesics. Participants were 42 chronic, low-back pain patients enrolled in a larger study examining problematic opioid analgesic use. Impulsivity was assessed using the BIS, sensation seeking was measured using the SSS, and opioid analgesic misuse risk was assessed using the Current Opioid Misuse Measure (COMM). Significant bivariate associations were found between the COMM and the following predictor variables: age and the three BIS subscales: Attentional Impulsiveness, Non-planning Impulsiveness, and Motor Impulsiveness. Using a multivariate linear regression, after controlling for age, the BIS subscales accounted for 29.0% of the variance in the COMM. Attentional Impulsiveness was the only significant BIS subscale. These results suggest a potential relationship between impulsivity, but not sensation seeking, and risk for opioid analgesic misuse. Impulsivity is not a prominent trait observed in chronic pain patients; however, it may be an important risk factor for opioid analgesic misuse for a subset of individuals with chronic pain. As such, these findings suggest that additional exploration of this potential risk factor is warranted.

  6. Prediction of Traffic Complexity and Controller Workload in Mixed Equipage NextGen Environments

    NASA Technical Reports Server (NTRS)

    Lee, Paul U.; Prevot, Thomas

    2012-01-01

    Controller workload is a key factor in limiting en route air traffic capacity. Past efforts to quantify and predict workload have resulted in identifying objective metrics that correlate well with subjective workload ratings during current air traffic control operations. Although these metrics provide a reasonable statistical fit to existing data, they do not provide a good mechanism for estimating controller workload for future air traffic concepts and environments that make different assumptions about automation, enabling technologies, and controller tasks. One such future environment is characterized by en route airspace with a mixture of aircraft equipped with and without Data Communications (Data Comm). In this environment, aircraft with Data Comm will impact controller workload less than aircraft requiring voice communication, altering the close correlation between aircraft count and controller workload that exists in current air traffic operations. This paper outlines a new trajectory-based complexity (TBX) calculation that was presented to controllers during a human-in-the-loop simulation. The results showed that TBX accurately estimated the workload in a mixed Data Comm equipage environment and the resulting complexity values were understood and readily interpreted by the controllers. The complexity was represented as a "modified aircraft account" that weighted different complexity factors and summed them in such a way that the controllers could effectively treat them as aircraft count. The factors were also relatively easy to tune without an extensive data set. The results showed that the TBX approach is well suited for presenting traffic complexity in future air traffic environments.

    2016-01-01

    The ISS provides an excellent opportunity for pioneering artificial intelligence software to meet the challenges of real-time communications (comm) link management. This opportunity empowers the ISS Program to forge a testbed for developing cognitive communications systems for the benefit of the ISS mission, manned Low Earth Orbit (LEO) science programs and future planetary exploration programs. In November, 1998, the Flight Operations Directorate (FOD) started the ISS Antenna Manager (IAM) project to develop a single processor supporting multiple comm satellite tracking for two different antenna systems. Further, the processor was developed to be highly adaptable as it supported the ISS mission through all assembly stages. The ISS mission mandated communications specialists with complete knowledge of when the ISS was about to lose or gain comm link service. The current specialty mandated cognizance of large sun-tracking solar arrays and thermal management panels in addition to the highly-dynamic satellite service schedules and rise/set tables. This mission requirement makes the ISS the ideal communications management analogue for future LEO space station and long-duration planetary exploration missions. Future missions, with their precision-pointed, dynamic, laser-based comm links, require complete autonomy for managing high-data rate communications systems. Development of cognitive communications management systems that permit any crew member or payload science specialist, regardless of experience level, to control communications is one of the greater benefits the ISS can offer new space exploration programs. The IAM project met a new mission requirement never previously levied against US space-born communications systems management: process and display the orientation of large solar arrays and thermal control panels based on real-time joint angle telemetry. However, IAM leaves the actual communications availability assessment to human judgement, which introduces

    Depuis plusieurs années, la môle hydatiforme partielle(MHP) a été considérée comme une entité bénigne qui ne nécessite pas une surveillance stricte comme celle de la môle complète(MC), mais l'apparition de quelques cas sporadiques de transformation de la môle partielle en maladie trophoblastique persistante que ça soit une môle invasive ou choriocarcinome ou voire même une tumeur du site d'implantation placentaire; a remis en question cette stratégie. A travers une observation d'une môle partielle invasive métastatique, et à travers une revue de la littérature, on a essayé d'appuyer cette conduite qui considère la môle partielle comme une pathologie potentiellement grave nécessitant une prise en charge adéquate et une surveillance assez rigoureuse.

    Objective To compare the investigator assessment of patient risk for prescription opioid misuse, abuse, and diversion with patient self-reports of these activities in a population with chronic pain. Methods As a secondary objective of an open-label, multicenter, primary care-based clinical study to evaluate the success of converting opioid-experienced patients with chronic pain to morphine sulfate with sequestered naltrexone hydrochloride, risk for misuse, abuse, and diversion was assessed using two nonvalidated questionnaires: one was completed by the investigator and another by the patient (Self-Reported Misuse, Abuse, and Diversion [SR-MAD]). In addition, the validated Current Opioid Misuse Measure (COMM) test and urine drug test were used. Results Of the 684 patients assessed by the investigators, 537 returned the self-assessment, SR-MAD. Most patients were assigned by the investigator as low risk for misuse (84.2%), abuse (89.3%), and diversion (94.3%). Of the patients who returned SR-MAD, 60% indicated having taken more opioids than prescribed and 10.9% reported chewing or crushing their opioids in the past. Of the patients who completed COMM, 40.6% were deemed as having aberrant behaviors. COMM results correlated with the risk levels from the investigator assessment. One-third of patients (33.8%) had at least one abnormal urine drug test result. Conclusion More research is needed to better understand the gap between the investigator assessment of potential risk for misuse, abuse, and diversion and the actual extent of these behaviors among patients with chronic pain.

The model is motivated, in particular, by the studies of coral broadcast spawning, where experimental observations of the efficiency of fertilization rates significantly exceed the data obtained from numerical models that do not take chemotaxis (attraction of sperm gametes by a chemical secreted by egg gametes) into account. We consider the case of the weakly coupled quadratic reaction term, which is the most natural from the biological point of view and was left open in Kiselev and Ryzhik ["Biomixing by chemotaxis and enhancement of biological reactions," Comm. Partial Differential Equations 37, 298-318 (2012)], 10.1080/03605302.2011.589879. The result is that similarly to Kiselev and Ryzhik ["Biomixing by chemotaxis and enhancement of biological reactions," Comm. Partial Differential Equations 37, 298-318 (2012)], 10.1080/03605302.2011.589879, the chemotaxis plays a crucial role in ensuring efficiency of reaction. However, mathematically, the picture is quite different in the quadratic reaction case and is more subtle. The reaction is now complete even in the absence of chemotaxis, but the timescales are very different. Without chemotaxis, the reaction is very slow, especially for the weak reaction coupling. With chemotaxis, the timescale and efficiency of reaction are independent of the coupling parameter.

  13. A Riemann-Hilbert approach to asymptotic questions for orthogonal polynomials

    A few years ago the authors introduced a new approach to study asymptotic questions for orthogonal polynomials. In this paper we give an overview of our method and review the results which have been obtained in Deift et al. (Internat. Math. Res. Notices (1997) 759, Comm. Pure Appl. Math. 52 (1999) 1491, 1335), Deift (Orthogonal Polynomials and Random Matrices: A Riemann-Hilbert Approach, Courant Lecture Notes, Vol. 3, New York University, 1999), Kriecherbauer and McLaughlin (Internat. Math. Res. Notices (1999) 299) and Baik et al. (J. Amer. Math. Soc. 12 (1999) 1119). We mainly consider orthogonal polynomials with respect to weights on the real line which are either (1) Freud-type weights d[alpha](x)=e-Q(x) dx (Q polynomial or Q(x)=x[beta], [beta]>0), or (2) varying weights d[alpha]n(x)=e-nV(x) dx (V analytic, limx-->[infinity] V(x)/logx=[infinity]). We obtain Plancherel-Rotach-type asymptotics in the entire complex plane as well as asymptotic formulae with error estimates for the leading coefficients, for the recurrence coefficients, and for the zeros of the orthogonal polynomials. Our proof starts from an observation of Fokas et al. (Comm. Math. Phys. 142 (1991) 313) that the orthogonal polynomials can be determined as solutions of certain matrix valued Riemann-Hilbert problems. We analyze the Riemann-Hilbert problems by a steepest descent type method introduced by Deift and Zhou (Ann. Math. 137 (1993) 295) and further developed in Deift and Zhou (Comm. Pure Appl. Math. 48 (1995) 277) and Deift et al. (Proc. Nat. Acad. Sci. USA 95 (1998) 450). A crucial step in our analysis is the use of the well-known equilibrium measure which describes the asymptotic distribution of the zeros of the orthogonal polynomials.

  14. Patient vs provider reports of aberrant medication-taking behavior among opioid-treated patients with chronic pain who report misusing opioid medication.

    During long-term opioid therapy for chronic noncancer pain, monitoring medication adherence of patients with a history of aberrant opioid medication-taking behaviors (AMTB) is an essential practice. There is limited research, however, into the concordance among existing monitoring tools of self-report, physician report, and biofluid screening. This study examined associations among patient and provider assessments of AMTB and urine drug screening using data from a randomized trial of a cognitive-behavioral intervention designed to improve medication adherence and pain-related outcomes among 110 opioid-treated patients with chronic pain who screened positive for AMTB and were enrolled in a pain program. Providers completed the Aberrant Behavior Checklist (ABC) and patients completed the Current Opioid Misuse Measure (COMM) and the Chemical Coping Inventory (CCI). In multivariate analyses, ABC scores were compared with COMM and CCI scores, while controlling for demographics and established risk factors for AMTB, such as pain severity. Based on clinical cutoffs, 84% of patients reported clinically significant levels of AMTB and providers rated 36% of patients at elevated levels. Provider reports of AMTB were not correlated with COMM or CCI scores. However, the ABC ratings of experienced providers (nurse practitioners/attending physicians) were higher than those of less experienced providers (fellows) and were correlated with CCI scores and risk factors for AMTB. Associations between patient- and provider-reported AMTB and urine drug screening results were low and largely nonsignificant. In conclusion, concordance between patient and provider reports of AMTB among patients with chronic pain prescribed opioid medication varied by provider level of training.

    A paper written for the SpaceOps 2012 Conference (Simplify ISS Flight Control Communications and Log Keeping via Social Tools and Techniques) identified three innovative concepts for real time flight control communications tools based on social mechanisms: a) Console Log Tool (CoLT) - A log keeping application at Marshall Space Flight Center's (MSFC) Payload Operations Integration Center (POIC) that provides "anywhere" access, comment and notifications features similar to those found in Social Networking Systems (SNS), b) Cross-Log Communication via Social Techniques - A concept from Johnsson Space Center's (JSC) Mission Control Center Houston (MCC-H) that would use microblogging's @tag and #tag protocols to make information/requests visible and/or discoverable in logs owned by @Destination addressees, and c) Communications Dashboard (CommDash) - A MSFC concept for a Facebook-like interface to visually integrate and manage basic console log content, text chat streams analogous to voice loops, text chat streams dedicated to particular conversations, generic and position-specific status displays/streams, and a graphically based hailing display. CoLT was deployed operationally at nearly the same time as SpaceOps 2012, the Cross- Log Communications idea is currently waiting for a champion to carry it forward, and CommDash was approved as a NASA Iinformation Technoloby (IT) Labs project. This paper discusses lessons learned from two years of actual CoLT operations, updates CommDash prototype development status, and discusses potential for using Cross-Log Communications in both MCC-H and/or POIC environments, and considers other ways for synergizing console applcations.

    Triton and Europa each display a variety of ridges and associated troughs. The resemblance of double ridges on these two satellites has been previously noted [R. Kirk, pers. comm.], but as yet, the similarities and differences between these feature types have not been examined in any detail. Triton s ridges, and Europa s, exhibit an evolutionary sequence ranging from isolated troughs, through doublet ridges, to complex ridge swaths [1, 2]. Comparison of ridges on Europa to those on Triton may provide insight into their formation on both satellites, and thereby have implications for the satellites' histories.

The experiment, performed at the Berkeley ALS, eliminates many systematic errors which have plagued previous attempts to measure R. The values of R obtained are about 25% below those previously reported but are in good agreement with several recent theoretical calculations. We also report preliminary results of triply differential cross sections for double ionization of He measured near threshold.

    Mark Twain once remarked “The coldest winter I ever spent was a summer in San Francisco.”If residents and visitors along the California coast think the summer of 1999 was even cooler than usual, they are right. Several air temperature records were set (R. Renard, pers. comm., 2000). October 1999 marked a 13-month run of below-normal temperatures at Monterey, and the March-July mean was 1.4°C below the long-term average.

    It has been determined that Saturn possesses a relatively pure dipolar magnetic field through magnetometer measurements made by Ness et al. (1979, private comm.) and Smith et al. (1979). The paper briefly outlines the dipole geomagnetic cutoff theory and demonstrates the scaling required for its applicability to energetic particle measurements in the vicinity of Saturn. Since the cutoff rigidity is a function of viewing direction, the effective cutoff rigidity must be determined as an integration over the finite viewing angle of a physical detector.

  19. Proprietes de Transport Electronique du Rutile Stoechiometrique

    NASA Astrophysics Data System (ADS)

    Keroack, Danielle

    Le rutile est un oxyde metallique qui presente beaucoup de similitudes avec certains perovskites notamment le titanate de barium ou de strontium. Il est comme ces derniers, compose d'un agencement d'octaedres d'oxygene centres sur l'atome de titane. Ces octaedres sont responsables de la forte polarisabilite de ces cristaux et de leur grande constante dielectrique. Leurs proprietes optiques, seuil d'absorption et spectre de phonons, sont par exemple forts semblables. La presente etude vise a determiner la nature du transport electronique dans le rutile stoechiometrique pur et d'en comparer les resultats avec les proprietes de certains perovskites. Nous determinerons par differentes mesures optoelectroniques les parametres caracteristiques des pieges et leur influence sur le transport des electrons et des trous. Les resultats de conductivite et de capacitance de meme que les spectres de photoconductivite dans nos echantillons ont mis en evidence la presence d'au moins cinq niveaux energetiques dans la bande interdite du rutile agissant comme pieges pour les electrons ou pour les trous et qui jouent un role de premiere importance dans le comportement electrique du rutile. Par la technique de charge transitoire, nous determinerons pour la premiere fois dans le rutile stoechiometrique la grandeur de la mobilite de derive des trous a la temperature ambiante soit 3,4 cm^2/V cdots et nous etablierons une borne superieure a la mobilite des electrons soit 0,1 cm^2 /Vcdots.

Plusiers cycles, Ecriture-Lecture-Effacement, ont ete enregistres dans cette matrice polymerique avec une resolution assez elevee. Une etude a ete menee afin d'obtenir la valeur des parametres comme l'epaisseur du film et l'intensite d'ecriture pour un angle d'enregistrement theta_{ acute ecriture} donne qui permettent d'obtenir les meilleures efficacites diffractionelles tout en preservant ce milieu de tout effet de fatigue ou de degradation. Ce polymere devient photorefractif une fois melange avec un bon accepteur de charge, le trinitrofluorenone et un bon chromophore non-lineaire, le disperse orange 25. Nous avons etudie experimentalement la conductivite en obscurite et la photoconductivite de ce materiau. Des simulations numeriques ont ete realisees en se basant sur le modele de Poole-Frenkel. Nous avons aussi etudie l'implantation de faisceaux d'ions d'oxygene d'energie 200 keV pour inscrire dans le PVCz un guide d'onde plan a profil d'indice.

  1. Scalable and Fault Tolerant Failure Detection and Consensus

    2015-01-01

    Future extreme-scale high-performance computing systems will be required to work under frequent component failures. The MPI Forum's User Level Failure Mitigation proposal has introduced an operation, MPI_Comm_shrink, to synchronize the alive processes on the list of failed processes, so that applications can continue to execute even in the presence of failures by adopting algorithm-based fault tolerance techniques. This MPI_Comm_shrink operation requires a fault tolerant failure detection and consensus algorithm. This paper presents and compares two novel failure detection and consensus algorithms. The proposed algorithms are based on Gossip protocols and are inherently fault-tolerant and scalable. The proposed algorithms were implemented and tested using the Extreme-scale Simulator. The results show that in both algorithms the number of Gossip cycles to achieve global consensus scales logarithmically with system size. The second algorithm also shows better scalability in terms of memory and network bandwidth usage and a perfect synchronization in achieving global consensus.

    The oopd1 particle-in-cell Monte Carlo (PIC-MC) code is used to simulate a capacitively coupled discharge in oxygen. oopd1 is a one-dimensional object-oriented PIC-MC code [1] in which the model system has one spatial dimension and three velocity components. It contains models for planar, cylindrical, and spherical geometries and replaces the XPDx1 series [2], which is not object-oriented. The revised oxygen model includes, in addition to electrons, the oxygen molecule in ground state, the oxygen atom in ground state, the negative ion O^-, and the positive ions O^+ and O2^+. The cross sections for the collisions among the oxygen species have been significantly revised from earlier work using the xpdp1 code [3]. Here we explore the electron energy distribution function (EEDF), the ion energy distribution function (IEDF) and the density profiles for various pressures and driving frequencies. In particular we investigate the influence of the O^+ ion on the IEDF, we explore the influence of multiple driving frequencies, and we do comparisons to the previous xpdx1 codes. [1] J. P.

    Un spectrogoniomètre de laboratoire utilisant comme source un tube émettant des radiations caractéristiques dans le domaine X mou et X-UV a été développé au Laboratoire de Chimie Physique (CNRS/UPMC) dans le cadre de l'Action Coordonnée Optique du CNRS. L'appareil comprend un monochromateur de type “double-cristaux" équipé de miroirs multicouches ou de cristaux de grande période et un goniomètre θ-2θ . Il permet des mesures de pouvoir réflecteur et de diffusion de dispositifs optiques, en particulier de miroirs et réseaux multicouches. Dans un futur proche il sera aussi destiné à la caractérisation de nouvelles sources et de détecteurs X-UV. L'appareil peut aussi être utilisé comme spectromètre à cristal plan si l'anode est remplacée par l'échantillon à analyser. Différents exemples des possibilités offertes par cet instrument opérant en mode “réflectométrie" ou en mode “spectrométrie" sont présentés.

    Geometrical constrains and intrinsic chirality in nematic mesophases enable formation of stable and metastable complex defect structures. Recently selected knotted and linked disclinations have been formed using laser manipulation of nematic braids entangling colloidal particles in nematic colloids [Tkalec et al., Science 2011; Copar et al., PNAS 2015]. In unwinded chiral nematic phases stable and metastable toron and hopfion defects have been implemented by laser tweezers [Smalyukh et al., Nature Materials 2010; Chen et al., PRL2013] and in chiral nematic colloids particles dressed by solitonic deformations [Porenta et al., Sci. Rep. 2014]. Modelling studies based on the numerical minimisation of the phenomenological free energy, supported with the adapted topological theory [Copar and Zumer, PRL 2011; Copar, Phys. Rep. 2014] allow describing the observed nematic defect structures and also predicting numerous structures in confined blue phases [Fukuda and Zumer, Nature Comms 2011 and PRL 2011] and stable knotted disclinations in cholesteric droplets with homeotropic boundary [Sec et al., Nature Comms 2014]. Coupling the modeling with finite difference time domain light field computation enables understanding of light propagation and light induced restructuring in these mesophases. The method was recently demonstrated for the description of low intensity light beam changes during the propagation along disclination lines [Brasselet et al., PRL 2009; Cancula et al., PRE 2014]. Allowing also high intensity light an order restructuring is induced [Porenta et al., Soft Matter 2012; Cancula et al., 2015]. These approaches help to uncover the potential of topological structures for beyond-display optical and photonic applications.

  5. Changing dietary behaviour: the role and development of practitioner communication.

    PubMed

    Whitehead, Kirsten

    2015-05-01

    The need to support people to change diet-related behaviour is widely advocated and how to do this effectively in practice is an expanding area of research. Important factors to consider are how healthcare practitioners communicate with their patients and how that communication may affect diet-related behaviour change and subsequent outcomes. The aim of the present paper is to discuss communication skills for behaviour change (CSBC), focusing predominantly on registered dietitians who are required to communicate effectively and have an important role in supporting patients to change diet-related behaviour. The views of dietitians in relation to CSBC have been investigated and respondents have consistently reported that they perceive these skills to be of vital importance in practice. Patient views have reiterated the importance of good CSBC in one-to-one consultations. However, pre-qualification training of dietitians is thought to deliver practitioners who are competent at a minimum level. The need for ongoing continuous professional development (CPD) in relation to CSBC has been recognised but currently most CPD focuses on updating knowledge rather than improving these essential skills. Measuring CSBC in a consistent and objective manner is difficult and an assessment tool, DIET-COMMS, has been developed and validated for this purpose. DIET-COMMS can be used to support CSBC development, but concerns about logistical challenges and acceptability of implementing this in practice have been raised. Although a suitable assessment tool now exists there is a need to develop ways to facilitate assessment of CSBC in practice.

    2003-02-01

    La diffraction de neutrons, sur monocristal ou sur échantillon polycristallin (ou poudre), est une technique très largement utilisée, en science des matériaux comme en biologie, lorsque l'on souhaite déterminer la structure cristalline d'un composé ou d'une molécule. Toutefois, le degré de précision de la détermination structurale est très corrélé au choix de l'instrument utilisé. Il s'en suit que la question “comment choisir l'instrument le mieux adapté au composé et à la problématique ?" apparaît comme fondamentale. L'objectif de ce cours est de tenter de répondre à cette question en décrivant brièvement les caractéristiques instrumentales de différents diffractomètres, en exposant les avantages spécifiques des expériences de diffraction de neutrons et en donnant quelques exemples d'application.

    Au Petén, entre les calcaires à grands foraminifères, algues et rudistes du Maastrichtien et les calcaires, marnes et argiles à foraminifères planctoniques et nannofossiles calcaires du Danien inférieur, affleurent soit des brèches à clastes de calcaires de plate-forme comme à El Caribe, soit une surface ferrugineuse comme à El Ceibo. L'origine des brèches a fait l'objet de controverses: tsunami dû à l'impact de la météorite de la limite Crétacé / Tertiaire sur le Yucatán versus baisse du niveau marin. La coupe d'El Ceibo fournit des données qui n'incitent pas à retenir pour ces brèches une origine liée à la vague d'impact. La comparaison des deux coupes plaiderait en faveur d'une origine tectonique.

  8. Comparison of Semi-Lagrangian Algorithms for Solving Vlasov-type Equations

    NASA Astrophysics Data System (ADS)

    2005-10-01

    In view of pursuing CRPP's effort in carrying out gyrokinetic simulations using an Eulerian-type approach [M. Brunetti et. al, Comp. Phys. Comm. 163, 1 (2004)], different alternative algorithms have been considered. The issue is to identify the most appropriate time-stepping scheme, both from a point of view of numerical accuracy and numerical efficiency. Our efforts have concentrated on two semi-Lagrangian approaches: The widely used cubic B-spline interpolation scheme, based on the original work of Cheng and Knorr [C. Z. Cheng and G. Knorr, J. Comp. Phys. 22, 330 (1976)], as well as the Cubic Interpolation Propagation (CIP) scheme, based on cubic Hermite interpolation, which has only more recently been applied for solving Vlasov-type equations [T. Nakamura and T. Yabe, Comp. Phys. Comm. 120, 122 (1999)]. The systematic comparison of these algorithms with respect to their basic spectral (diffusion/dispersion) properties, as well as their ability to avoid the overshoot (Gibbs) problem, is first presented. Results from solving a guiding-center model of the two-dimensional Kelvin-Helmholtz instability are then compared. This test problem enables to address some of the key technical issues also met with the more complex gyrokinetic-type equations.

  9. "Any movement at all is exercise": a focused ethnography of rural community-dwelling older adults' perceptions and experiences of exercise as self-care.

    PubMed

    Graham, Laura J; Connelly, Denise M

    2013-01-01

    Objectif : Comprendre les valeurs, les croyances et les comportements partagés des participants adultes âgés vivant dans des logements communautaires en ce qui concerne l'exercice comme soins autodirigés. Méthode : Nous avons procédé à une ethnographie convergente constructiviste comportant des entrevues semi-structurées et l'observation de participants, qui a porté sur 17 personnes de 65 ans et plus. Les entrevues ont été transcrites et codées de façon inductive de façon à dégager des thèmes liés à l'exercice, aux soins autodirigés et à l'exercice comme soins autodirigés. On a comparé les notes pratiques aux entrevues de suivi et au dialogue entre les auteurs afin d'améliorer l'interprétation. Résultats : Les participants ont décrit l'exercice de façon générale comme le fait de bouger et non un comportement central des soins autodirigés. La sensibilisation à l'importance de l'exercice et à ses bienfaits pour la santé a toutefois augmenté après un événement important lié à la santé personnelle. Les participants préféraient un exercice agréable et qu'ils connaissaient déjà. Conclusions : Il peut être particulièrement efficace de prescrire des exercices à des adultes âgés si l'on vise une activité physique agréable et déjà connue et si l'activité consiste aussi à interpréter des lignes directrices sur l'exercice et des principes d'entraînement par rapport à des problèmes chroniques et à des bienfaits possibles pour la santé.

    Objet: Déterminer les effets de l'utilisation à court et à long terme du drainage autogène (DA) sur la fonction pulmonaire et la récupération de crachat chez les personnes qui ont la fibrose kystique (FK). Méthodes: Les auteurs ont procédé à un examen systématique d'essais cliniques randomisés et quasi-randomisés où les participants étaient des personnes vivant avec la FK qui utilisent le DA comme seule méthode de dégagement des voies aériennes (DVA) Résultats: Les recherches effectuées dans quatre bases de données et des sources secondaires au moyen de cinq termes clés ont produit 735 articles dont 58 contenaient les expressions « drainage autogène » et « fibrose kystique ». On a inclus finalement quatre études dont deux à long terme. Toutes les études ont mesuré le volume expiratoire maximum seconde (VEMS1) et n'ont constaté aucun changement. Des études de longue durée n'avaient pas le pouvoir nécessaire pour détecter tout changement du VEMS1, mais des études de courte durée ont constaté une production cliniquement significative de crachat (≥4 grammes). Conclusion: Il a été démontré, dans un nombre limité d'enquêtes, que le DA produit des volumes cliniquement significatifs de crachat. L'effet du DA sur le fonctionnement de l'appareil pulmonaire demeure incertain et des questions ont surgi au sujet de la pertinence du VEMS1 comme mesure valide du dégagement des voies aériennes à partir des régions pulmonaires périphériques. Il faudrait envisager d'utiliser le VEMS1 comme mesure première de l'effet du DA.

  11. An updated review of the optimal lithium dosage regimen for renal protection.

    PubMed

    Carter, Lorie; Zolezzi, Monica; Lewczyk, Andrea

    2013-10-01

    Objectif : Malgré plusieurs décennies de recherche, il y a encore de l’incertitude concernant la posologie optimale du lithium associée au risque réduit d’effets rénaux, comme la polyurie, chez les patients souffrant du trouble bipolaire affectif. Nous présentons une revue mise à jour de la littérature afin d’offrir aux prescripteurs une recommandation éclairée de régime posologique. Méthode : Cette recherche a été menée à partir des grandes bases de données MEDLINE et Embase à l’aide de termes comme : lithium, horaire d’administration des médicaments, relation dose–réponse, une fois par jour, deux fois par jour, et libération prolongée. En outre, les bibliographies de publications connexes ont fait l’objet d’une recherche manuelle. Résultats : Un total de 20 essais ont été inclus. Certains essais montraient une réduction du volume d’urine avec une dose unique quotidienne (DUQ), alors que d’autres n’indiquaient aucun changement. Le seul essai qui évaluait les patients qui commençaient le lithium a observé une réduction de la fréquence urinaire avec la DUQ après 21 jours. Les essais examinant les résultats de biopsie rénale ont constaté que les doses multiples quotidiennes étaient associées à plus de dommages pathologiques aux reins. Les posologies de DUQ étaient généralement bien tolérées, et aucune réduction d’efficacité n’a été notée dans tous les essais. Conclusions : Les données probantes disponibles sont contradictoires sur le fait que la DUQ de lithium réduise la polyurie; cependant, aucun essai n’a démontré un désavantage de la DUQ en ce qui concerne l’efficacité prophylactique ou les effets indésirables. Étant donné les avantages ajoutés de la DUQ, comme une meilleure observance, nous recommandons aux patients qui commencent le lithium de se convertir à une DUQ de lithium au coucher, une fois que la dose quotidienne appropriée est déterminée.

    Objectif : La réadaptation est de plus en plus reconnue comme une intervention thérapeutique importante pour les personnes aux prises avec un cancer. Le principal objectif de cette étude était d'analyser les modèles de pratique actuels pour la prestation de réadaptation en oncologie au Canada. Méthode : Une enquête descriptive transversale a été réalisée en ligne auprès d'établissements canadiens offrant des traitements contre le cancer ou répertoriés comme établissant des services de réadaptation aux personnes souffrant de cancer, au cours ou après leur traitement (centres d'oncologie, hôpitaux de réadaptation, centres de santé communautaires et cliniques privées). Résultats : Des 116 établissements contactés, 62 ont rempli le questionnaire et de ce nombre, 20 ont dit être dotés d'un programme de réadaptation en oncologie. La majorité des répondants ont dit ne pas répondre entièrement aux besoins de leur clientèle en matière de réadaptation. Les programmes de réadaptation y sont offerts par des équipes multidisciplinaires qui comportent un physiothérapeute dans la majorité des cas. Le financement et la disponibilité des ressources ont été déterminés comme étant les principaux obstacles au développement de réels programmes de réadaptation en oncologie. Conclusions : Les programmes officiels de réadaptation en oncologie semblent rares, malgré un nombre croissant de preuves que ce type d'intervention offre des avantages tangibles dans le cadre du continuum de survie au cancer.

  13. ERKN integrators for systems of oscillatory second-order differential equations

    NASA Astrophysics Data System (ADS)

    Wu, Xinyuan; You, Xiong; Shi, Wei; Wang, Bin

    2010-11-01

    For systems of oscillatory second-order differential equations y+My=f with M∈R, a symmetric positive semi-definite matrix, X. Wu et al. have proposed the multidimensional ARKN methods [X. Wu, X. You, J. Xia, Order conditions for ARKN methods solving oscillatory systems, Comput. Phys. Comm. 180 (2009) 2250-2257], which are an essential generalization of J.M. Franco's ARKN methods for one-dimensional problems or for systems with a diagonal matrix M=wI [J.M. Franco, Runge-Kutta-Nyström methods adapted to the numerical integration of perturbed oscillators, Comput. Phys. Comm. 147 (2002) 770-787]. One of the merits of these methods is that they integrate exactly the unperturbed oscillators y+My=0. Regretfully, even for the unperturbed oscillators the internal stages Y of an ARKN method fail to equal the values of the exact solution y(t) at t+ch, respectively. Recently H. Yang et al. proposed the ERKN methods to overcome this drawback [H.L. Yang, X.Y. Wu, Xiong You, Yonglei Fang, Extended RKN-type methods for numerical integration of perturbed oscillators, Comput. Phys. Comm. 180 (2009) 1777-1794]. However, the ERKN methods in that paper are only considered for the special case where M is a diagonal matrix with nonnegative entries. The purpose of this paper is to extend the ERKN methods to the general case with M∈R, and the perturbing function f depends only on y. Numerical experiments accompanied demonstrates that the ERKN methods are more efficient than the existing methods for the computation of oscillatory systems. In particular, if M∈R is a symmetric positive semi-definite matrix, it is highly important for the new ERKN integrators to show the energy conservation in the numerical experiments for problems with Hamiltonian H(p,q)=1/2 >pp+1/2 >qMq+V(q) in comparison with the well-known methods in the scientific literature. Those so called separable Hamiltonians arise in many areas of physical sciences, e.g., macromolecular dynamics, astronomy, and classical

    A human-in-the-loop simulation was conducted that examined separation assurance concepts in varying levels of traffic density with mixtures of aircraft equipage and automation. This paper's analysis focuses on one of the experimental conditions in which traffic levels were approximately fifty percent higher than today, and approximately fifty percent of the traffic within the test area were equipped with data communications (data comm) capabilities. The other fifty percent of the aircraft required control by voice much like today. Within this environment, the air traffic controller participants were provided access to tools and automation designed to support the primary task of separation assurance that are currently unavailable. Two tools were selected for analysis in this paper: 1) a pre-probed altitude fly-out menu that provided instant feedback of conflict probe results for a range of altitudes, and 2) an interactive auto resolver that provided on-demand access to an automation-generated conflict resolution trajectory. Although encouraged, use of the support tools was not required; the participants were free to use the tools as they saw fit, and they were also free to accept, reject, or modify the resolutions offered by the automation. This mode of interaction provided a unique opportunity to examine exactly when and how these tools were used, as well as how acceptable the resolutions were. Results showed that the participants used the pre-probed altitude fly-out menu in 14% of conflict cases and preferred to use it in a strategic timeframe on data comm equipped and level flight aircraft. The interactive auto resolver was also used in a primarily strategic timeframe on 22% of conflicts and that their preference was to use it on conflicts involving data comm equipped aircraft as well. Of the 258 resolutions displayed, 46% were implemented and 54% were not. The auto resolver was rated highly by participants in terms of confidence and preference. Factors such as

    Objectif : Identifier les caractéristiques des personnes souffrant d'arthrose du genou ou de la hanche qui se rendent à un centre de triage régional pour une première consultation et sont considérées comme n'étant pas prêtes pour une arthroplastie totale des articulations (ATA). Méthodes : Des notes de première consultation (n=482) ont été examinées de manière rétrospective. Des variables prédictives ont d'abord été tirées de la recension des écrits à ce sujet, puis 14 de ces variables se sont avérées convenables pour une inclusion dans des analyses de régression logistique multiple par étapes. Résultats : Sur les 222 personnes admissibles, 131 (59 %) ont été considérées comme n'étant pas prêtes pour une ATA. Cinq variables ont été entrées dans le modèle ([Formula: see text]=133,19, p<0,001) pour un taux global de réussite de 81,1 %. Les personnes considérées comme n'étant pas prêtes pour une ATA étaient plus susceptibles de souffrir d'arthrose du genou (hanche et genou; rapport de cotes [RC]=0,352, p=0,018), de souffrir d'arthrose moins grave (RC=0,246 pour chaque augmentation de catégorie de gravité, p<0,001), de n'utiliser aucune aide à la marche (canne et aucune aide à la marche; RC=0,390, p=0,033) et d'avoir des résultats plus élevés à l'échelle fonctionnelle des membres inférieurs (RC=1,050 pour chaque augmentation d'un point, p=0,003) et des articulations en meilleur état selon le score des échelles de hanche Harris et de la Knee Society (RC=3,946 pour chaque augmentation de catégorie, p=0,007). Conclusion : Le fait de tenir compte des caractéristiques énumérées ci-dessus aidera les cliniciens à identifier les personnes qui pourraient avoir besoin d'une intervention autre que l'ATA.

    Synopsis An O/W emulsion with a lipopeptidic emulsifier was optimized by means of two different methods, specifically by experimental design and by selective variation of the parameters. Two optimized emulsions were obtained; they had similar values of emulsification (time and rate of homogenization) and amounts of components. Résumé Une émulsion O/E, avec un lipopeptide comme tensioactif, a été optimisée par deux méthodes d'optimisation différentes, notamment par l'experimental design et par la variation selective de certain paramètres. Deux émulsions optimisées ont été ainsi obtenues: ces émulsions ont des valeurs d'emulsification (temp et vitesse d'homogénéisation) et des quantités des composantes très proches.

    La spectroscopie Raman fournit une analyse détaillée de la structure chimique d'un objet, à température ambiante. La section efficace de diffusion Raman d'un objet petit est souvent faible et son signal ne pourra être détecté sans utiliser un processus d'exaltation efficace de la diffusion. Cet article décrit quelques avancées dans le domaine de l'exaltation de surface de la diffusion Raman. Il est illustré par des résultats expérimentaux que nous avons obtenus sur des molécules uniques. Parfois, le signal de certains objets petits peut être détecté sans effet d'exaltation supplémentaire, comme le montre l'exemple de nanotubes remplis, dits peapods.

    2015-11-01

    In the present work we study the motion of microorganisms swimming by an axisymmetric distribution of surface tangential velocity in a weakly viscoelastic fluid. The second-order fluid constitutive equation is used to model the suspending fluid, while the well-known "squirmer model" [M. J. Lighthill, Comm. Pure Appl. Math. 5, 109 (1952); J. R. Blake, J. Fluid Mech. 46, 199 (1971)] is employed to describe the organism propulsion mechanism. A regular perturbation expansion up to first order in the Deborah number is performed, and the generalized reciprocity theorem from Stokes flow theory is then used, to derive analytical formulas for the squirmer velocity. Results show that "neutral" squirmers are unaffected by viscoelasticity, whereas "pullers" and "pushers" are slowed down and hastened, respectively. The power dissipated by the swimming microorganism and the "swimming efficiency" are also analytically quantified.

    Objectifs : Rechercher s’il y a des tendances dans l’incidence du trouble de la personnalité limite (TPL) traité dans des hôpitaux psychiatriques danois selon différents systèmes diagnostiques, de 1970 à 2009. Méthodes : Tous les patients ayant reçu un diagnostic de TPL pour la première fois comme diagnostic principal ou auxiliaire et traités comme patients externes ou hospitalisés d’hôpitaux psychiatriques danois ont été identifiés grâce au registre danois central de recherche en psychiatrie. Les taux normalisés selon l’âge, le sexe, ont été calculés avec la Classification internationale des maladies (CIM), 8e révision, pour la période diagnostique de 1970 à 1993 et la CIM-10 pour la période diagnostique de 1994 à 2009. Résultats : L’incidence du TPL chez les femmes comme diagnostic principal ou secondaire a augmenté de façon linéaire de 1970 à 2009 (β = 0,69 par 100 000 par an [IC à 95 % 0,66 à 0,73]). Les taux chez les hommes ont aussi augmenté de façon linéaire de 1970 à 1993 (β = 0,37 [IC à 95 % 0,30 à 0,43]), suivis d’une décroissance linéaire (β = –0,22 [IC à 95 % –0,29 à –0,15]) dans la période utilisant la CIM-10 entre 1994 et 2009. L’augmentation du TPL chez les femmes est plus faible après le milieu des années 1990, après contrôle pour les patients externes obligatoirement inscrits depuis 1995. Conclusion : L’absence de critères définis du TPL dans la CIM-8 peut avoir été interprétée sommairement comme équivalant au concept déterminant de Kernberg sur l’organisation de personnalité limite, donnant suite à des taux semblables pour les hommes et les femmes. Cependant, dans la CIM-10, les cliniciens utilisant des critères plus ciblés pour le trouble de personnalité émotionnellement instable (de type limite) tendaient à diagnostiquer le TPL plus souvent chez les femmes. Ces résultats suggèrent l’importance d’utiliser des critères diagnostiques spécifiques. Ils

    In July of 1997 we obtained 39 HST images of Neptune and satellites in the BVI filters for photometric, as well as astrometric and dynamical studies. Our preliminary photometric reductions (Pascu et al. BAAS 30 1101, 1998) indicated leading/trailing brightness asymmetries for both Triton and Proteus, as well as a large color difference between the two moons. The color difference, in (B-V) and (V-I), implied an unusually blue color for Proteus, or a red color for Triton. However, HST/NICMOS observations indicate that Proteus is a red object (B.A. Smith 1998, Pers. Comm.), and Buratti et al. (BAAS 30 1107, 1998) report a reddening in Triton's spectrum in observations made in October, 1997. We have reanalyzed our observations, with results in substantial agreement with our earlier determinations. We are now left with the conclusion that we have observed an "episodic" reddening of Triton, of the type described by Buratti et al. (Icarus 110, 1994).

    We have used recoil momentum spectroscopy (COLTRIMS (J. Ullrich, et al., Comm. At. Mol. Phys. \\underline30), 285 (1994).) to determine final state momentum distributions in the single electron capture from He by 10 MeV F^8+ ions. A momentum resolution below 0.15 a.u. was obtained. The longitidunal momentum resolution is sufficient to allow the separation of final state populations of the L, M and higher states, and to identify excitation of the residual He^+ ion. This probability of this excitation is large in the capture process. Transverse momentum distributions were used to extract transverse cross sections (angular distributions) for different final states. Comparison of the data to theoretical expectations will be presented.

    This paper presents a comprehensive review and assessment of a demonstration technology transfer and commercialization prouram called "CommTech". The pro-ram was conceived and initiated in early to mid-fiscal year 1995, and extended roughly three years into the future. Market research sources were used to initially gather primary technological problems and needs data from non-aerospace companies in three targeted industry sectors: environmental, surface transportation, and bioengineering. Company-supplied information served as input data to activate or start-up an internal, phased matchmaking process. This process was based on technical-level relationship exploration followed by business-level agreement negotiations. and culminated with project management and execution. Space Act Agreements represented near-term outputs. Company product or process commercialization derived from NASA Glenn support and measurable economic effects represented far-term outputs.

    Nous avons propose la nouvelle combinaison de materiaux, C/Si, pour la fabrication de miroirs multicouches a incidence normale dans la region spectrale 25-40 nm. Les resultats experimentaux montrent que cette combinaison possede une reflectivite d'environ ~25% dans la region spectrale 25-33 nm et une reflectivite d'environ ~23% dans la region spectrale 33-40 nm. Ces valeurs de reflectivite sont les plus grandes obtenues jusqu'a maintenant dans la region spectrale 25-40 nm. Les miroirs multicouches ont ete par la suite caracterises par microscopie electronique a transmission, par diverses techniques de diffraction des rayons X et par spectroscopies d'electrons AES et ESCA. La resistance des miroirs aux temperatures elevees a ete egalement etudiee. Les resultats fournis par les methodes de caracterisation indiquent que cette combinaison possede des caracteristiques tres prometteuses pour son application comme miroir pour les rayons X mous.

    2007-11-01

    The classical one-dimensional Child-Langmuir law has been extended to two dimensions by numerical simulation in planar geometries [1]. By considering an axisymmetric cylindrical system with emission radius r, outer radius R > r, and gap length L, we further examine the space charge limit in two dimensions. The ratio of the observed current density limit JCL2 to the theoretical one-dimensional value JCL1 is found to be a monotonically decreasing function of the ratio of emission area (r^2) to gap separation (L). This result is in agreement with the planar results, where the emission area is proportional to the cathode width (r) [1]. The simulations were run in the particle in cell code, OOPIC [2]. [1] J. W.

  18. Local energy decay for linear wave equations with variable coefficients

    NASA Astrophysics Data System (ADS)

    Ikehata, Ryo

    2005-06-01

    A uniform local energy decay result is derived to the linear wave equation with spatial variable coefficients. We deal with this equation in an exterior domain with a star-shaped complement. Our advantage is that we do not assume any compactness of the support on the initial data, and its proof is quite simple. This generalizes a previous famous result due to Morawetz [The decay of solutions of the exterior initial-boundary value problem for the wave equation, Comm. Pure Appl. Math. 14 (1961) 561-568]. In order to prove local energy decay, we mainly apply two types of ideas due to Ikehata-Matsuyama [L2-behaviour of solutions to the linear heat and wave equations in exterior domains, Sci. Math. Japon. 55 (2002) 33-42] and Todorova-Yordanov [Critical exponent for a nonlinear wave equation with damping, J. Differential Equations 174 (2001) 464-489].

  1. QUANTUM CONTROL OF LIGHT: From Slow Light and FAST CARS to Nuclear γ-ray Spectroscopy

    NASA Astrophysics Data System (ADS)

    Scully, Marlan

    2007-06-01

    In recent work we have demonstrated strong coherent backward wave oscillation using forward propagating fields only. This surprising result is achieved by applying laser fields to an ultra-dispersive medium with proper chosen detunings to excite a molecular vibrational coherence that corresponds to a backward propagating wave [PRL, 97, 113001 (2006)]. The physics then has much in common with propagation of ultra-slow light. Applications of coherent scattering and remote sensing to the detection of bio and chemical pathogens (e.g., anthrax) via Coherent Anti-Raman Scattering together with Femtosecond Adaptive Spectroscopic Techniques (FAST CARS [Opt. Comm., 244, 423 (2005)]) will be discussed. Furthermore, the interplay between quantum optics (Dicke super and sub-radiant states) and nuclear physics (forward scattering of γ radiation) provides interesting problems and insights into the quantum control of scattered light [PRL, 96, 010501 (2005)].

  2. Etude des Abondances de MG et de fe dans la Composante Stellaire des Disques des Galaxies Spirales

    NASA Astrophysics Data System (ADS)

    Beauchamp, Dominique

    Je presente ici une technique d'observation par imagerie des disques stellaires des galaxies spirales. Je tente, a l'aide d'un modele evolutif multiphase, de determiner les abondances de fer et de magnesium dans les disques. Dans ce but, je mesure les indices Mg2 et Fe5270 du systeme de Lick. Ces elements representent un choix judicieux d'indicateurs car ils sont formes par des supernovae de deux types differents ayant des durees de vie differentes. Le rapport d'abondances de ces deux elements est un indicateur du taux de formation des populations stellaires. Je decris, en premier lieu, les observations, la technique de mesure, ainsi que son application. J'analyse ensuite les indices mesures. A partir du modele multiphase, j'explore differents parametres physiques des spirales comme le taux de formation stellaire, l'evolution des abondances, les effets possibles de la presence de la barre, etc.

  3. Form II of adipic acid-nicotinohydrazide (1/2).

    Lemmerer, Andreas; Bernstein, Joel; Kahlenberg, Volker

    2012-01-01

    The crystal structure of the title co-crystal, 2C(6)H(7)N(3)O·C(6)H(10)O(4), is a second polymorph, designated form II, of the co-crystal formed between the two mol-ecules [Lemmerer et al. (2011 ▶). CrystEngComm, 13, 55-59]. The asymmetric unit comprises one mol-ecule of nicotinic acid hydrazide, and one half-mol-ecule of adipic acid (the entire mol-ecule is completed by the application of a centre of inversion). In the crystal, mol-ecules assemble into a three-dimensional network of hydrogen bonds, formed by three N-H⋯O hydrogen bonds and one O-H⋯N hydrogen bond. The O-H⋯N hydrogen bond formed between the carboxyl group and the pyridine ring is supported by a C-H⋯O hydrogen bond.

    2015-01-01

    Nous rapportons deux cas d'infection à Pseudomonas aeruginosa: un cas de méningite et un cas d'infection urinaire. Les auteurs rappellent qu’à côté des étiologies classiques des méningites et des infections urinaires, des germes résistants comme Pseudomonas aeruginosa peuvent être responsables d'infections à localisation méningées et urinaires et dont il faut connaître pour une bonne prise en charge. Le traitement de ces infections requiert un antibiogramme au regard de la grande capacité de résistance de Pseudomonas aeruginosa en milieu hospitalier. La limitation des gestes invasifs et l'application rigoureuse des mesures de prévention des infections en milieu hospitalier contribueront à lutter efficacement contre ces infections en milieu de soins.

    Objectif : Décrire les caractéristiques des participants à un programme de triage en fonction de leurs problèmes à la colonne vertébrale, comparer les profils des patients pour qui une chirurgie était ou non recommandée et déterminer l'étendue de la chirurgie parmi les personnes dirigées vers un professionnel de la chirurgie. Méthode : Les données ont été recueillies rétrospectivement en procédant à un examen des dossiers de personnes qui ont utilisé le service pendant trois ans (de 2003 à 2006). Des données relatives à 1 096 personnes étaient disponibles et des données complètes étaient disponibles pour 299 personnes. Des statistiques descriptives ont été utilisées pour résumer les données démographiques, les caractéristiques cliniques et les recommandations de gestion. Les caractéristiques des personnes ayant ou non fait l'objet d'une recommandation pour une chirurgie ont été examinées à l'aide du test du Khi-carré de Pearson et du test de Fisher. Résultats : La majorité des 746 participants ont été classés comme « mécanique vertébrale » (92,5 %); 2,9 % comme « autres parties du corps »; 2,5 % l'ont été dans « médical/autres » et 2 % ont été classés comme « vertébral chirurgical ». Les recommandations pour une intervention (par un chirurgien) étaient formulées indépendamment de l'âge des patients, de leur sexe, de la durée des symptômes, de leur milieu (urbain ou rural), de la source de financement des soins de santé dans leur cas et du diagnostic posé. L'étendue de la chirurgie était de 80 %. Conclusions : La plupart des personnes n'étaient pas considérées comme des candidats pour une chirurgie. L'évaluation du triage par des physiothérapeutes peut accroître l'efficacité du travail du chirurgien orthopédique en réduisant le nombre de renvois en consultation de personnes qui n'ont pas besoin d'une chirurgie et favoriser par le fait même un accès en temps opportun

  6. A repeating source of infrasound from the Wells, Nevada earthquake sequence

    Arrowsmith, Stephen J.; Whitaker, Rod; Randall, George; Burlacu, Relu

    2009-01-01

    The Wells, Nevada earthquake of February 21, 2008, generated a complex seismoacoustic wakefield. In addition to epicentral infrasound, the earthquake triggered a secondary source of infrasound, which was also initiated by subsequent aftershocks. By applying simple constraints on the propagation of seismic and infrasound waves, we show that the secondary source is an isolated peak that appears to efficiently generate infrasound through the interaction with seismic surface waves. By measuring peak-to-peak amplitudes of epicentral and secondary arrivals and correcting them for the effects of distance and winds, we find that epicentral arrivals lit with empirical relationships of Mutschlecner and Whitaker (2005) and Le Pichon et al. (2006), which form the basis for a proposed infrasound discriminant (Anderson et al., Pers. Comm.). In contrast, the secondary arrivals are much higher in amplitude, highlighting the importance of being able to separate epicentral and secondary arrivals for infrasonic event discrimination.

    Le fibromatosis colli (FC) est pseudotumeur rare du muscle sterno-cléido-mastoïdien (SCM), à l'origine d'un torticolis dit congénital chez le nouveau-né ou le nourrisson. Le mécanisme étio-pathogénique de sa survenue est sujet à controverse. Son diagnostic fait appel à l’échographie qui permet de mettre en évidence un épaississement caractéristique du muscle. Nous rapportons deux cas diagnostiqués par l’échographie avec pour un cas une notion de malposition intra-utérine et pour l'autre cas une absence totale de malposition et de traumatisme obstétrical qui pourtant est évoqué comme élément du mécanisme de survenue du FC.

  10. Protection des ions organiques contre les dommages induits a l'ADN par les electrons de basse energie

    NASA Astrophysics Data System (ADS)

    Dumont, Ariane

    Il a ete demontre que les electrons de basse energie (EBE) peuvent induire des cassures simple brin (CSB) a l'ADN, via la formation d'anions transitoires qui decroissent par attachement dissociatif, ou dans d'autres etats electroniques dissociatifs menant a la fragmentation. Afin d'effectuer une etude complete des effets des electrons de basse energie sur la matiere biologique, il est necessaire de comprendre leur mecanismes d'interaction non seulement avec l'ADN, mais avec les constituants de son environnement. Les histones sont une composante importante de l'environnement moleculaire de l'ADN. Leur charge positive leur permet de s'associer aux groupements phosphate anionique de l'ADN. Le role principal de ces proteines basiques consiste a organiser l'ADN et l'empaqueter afin de former la chromatine. Les cations sont une autre composante importante de la cellule; ils jouent un role dans la stabilisation de la conformation B de l'ADN in vitro par leurs interactions avec les petits et grands sillons de l'ADN, ainsi qu'avec le groupement phosphate charge negativement. Avec les histones, ils participent egalement a la compaction de l'ADN pour former la chromatine. Cette etude a pour but de comprendre comment la presence d'ions organiques (sous forme de Tris et d'EDTA) a proximite de l'ADN modifie le rendement de cassures simple brin induit par les electrons de basse energie. Le Tris et l'EDTA ont-ete choisis comme objet d'etude, puisqu'en solution, ils forment le tampon standard pour solubiliser l'ADN dans les experiences in vitro (10mM Tris, 1mM EDTA). De plus, la molecule Tris possede un groupement amine alors que l'EDTA possede 4 groupements carboxyliques. Ensembles, ils peuvent se comporter comme un modele simple pour les acides amines. Le ratio molaire de 10 :1 de Tris par rapport a l'EDTA a pour but d'imiter le comportement des histones qui sont riches en arginine et lysine, acides amines possedant un groupement amine charge positivement additionnel.

  11. Perturbation Theory for Parent Hamiltonians of Matrix Product States

    NASA Astrophysics Data System (ADS)

    Szehr, Oleg; Wolf, Michael M.

    2015-05-01

    This article investigates the stability of the ground state subspace of a canonical parent Hamiltonian of a Matrix product state against local perturbations. We prove that the spectral gap of such a Hamiltonian remains stable under weak local perturbations even in the thermodynamic limit, where the entire perturbation might not be bounded. Our discussion is based on preceding work by Yarotsky that develops a perturbation theory for relatively bounded quantum perturbations of classical Hamiltonians. We exploit a renormalization procedure, which on large scale transforms the parent Hamiltonian of a Matrix product state into a classical Hamiltonian plus some perturbation. We can thus extend Yarotsky's results to provide a perturbation theory for parent Hamiltonians of Matrix product states and recover some of the findings of the independent contributions (Cirac et al in Phys Rev B 8(11):115108, 2013) and (Michalakis and Pytel in Comm Math Phys 322(2):277-302, 2013).

    2006-03-01

    The successful CPM {P,N} methods for the one-dimensional time-independent Schrödinger problem are generalized to the coupled channel case. The derivation of the formulae is discussed and a MAPLE program code is included which allows to determine the analytic expressions of the perturbation corrections needed to construct methods of different orders. Some numerical illustrations are given showing the accuracy, the robustness and the CPU-time gain of the proposed algorithms over the sixth order LILIX method which was presented in [L.Gr. Ixaru, LILIX—A package for the solution of the coupled channel Schrödinger equation, Comput. Phys. Comm. 147 (2002) 834-852].

    The Open Provenance Model is a model of provenance that is designed to meet the following requirements: (1) To allow provenance information to be ex- changed between systems, by means of a compatibility layer based on a shared provenance model. (2) To allow developers to build and share tools that operate on such a provenance model. (3) To deFIne provenance in a precise, technology- agnostic manner. (4) To support a digital representation of provenance for any “thing, whether produced by computer systems or not. (5) To allow multiple levels of description to coexist. (6) To deFIne a core set of rules that identify the valid inferences that can be made on provenance representation. This docu- ment contains the speciFIcation of the Open Provenance Model (v1.1) resulting from a commChallenge.

    Ahmed, Chaara El Mouez

    Nous avons etudie les relations de dispersion et la diffusion des glueballs et des mesons dans le modele U(1)_{2+1} compact. Ce modele a ete souvent utilise comme un simple modele de la chromodynamique quantique (QCD), parce qu'il possede le confinement ainsi que les etats de glueballs. Par contre, sa structure mathematique est beaucoup plus simple que la QCD. Notre methode consiste a diagonaliser l'Hamiltonien de ce modele dans une base appropriee de graphes et sur reseau impulsion, afin de generer les relations de dispersion des glueballs et des mesons. Pour la diffusion, nous avons utilise la methode dependante du temps pour calculer la matrice S et la section efficace de diffusion des glueballs et des mesons. Les divers resultats obtenus semblent etre en accord avec les travaux anterieurs de Hakim, Alessandrini et al., Irving et al., qui eux, utilisent plutot la theorie des perturbations en couplage fort, et travaillent sur un reseau espace-temps.

    1989-05-01

    Dearchival of image data in the form of x-ray film provides a major challenge for radiology departments. In highly active referral environments such as tertiary care hospitals, patients may be referred to multiple clinical subspecialists within a very short time. Each clinical subspecialist frequently requires diagnostic image data to complete the diagnosis. This need for image access often interferes with the normal process of film handling and interpretation, subsequently reducing the efficiency of the department. The concept of creating a local image database on individual nursing stations utilizing the AT&T CommView Results Viewing Station (RVS) is being evaluated. Initial physician acceptance has been favorable. Objective measurements of operational productivity enhancements are in progress.

    Path Loss Measurements were obtained on three (3) GPS equipped 757 aircraft. Systems measured were Marker Beacon, LOC, VOR, VHF (3), Glide Slope, ATC (2), DME (2), TCAS, and GPS. This data will provide the basis for assessing the EMI (Electromagnetic Interference) safety margins of comm/nav (communication and navigation) systems to portable electronic device emissions. These Portable Electronic Devices (PEDs) include all devices operated in or around the aircraft by crews, passengers, servicing personnel, as well as the general public in the airport terminals. EMI assessment capability is an important step in determining if one system-wide PED EMI policy is appropriate. This data may also be used comparatively with theoretical analysis and computer modeling data sponsored by NASA Langley Research Center and others.

    La cardiomyopathie du péripartum ou cardiomyopathie gravidique primitive, est une entité rare et méconnue définie comme une insuffisance cardiaque systolique survenant le dernier mois de la grossesse ou les cinq premiers mois du postpartum en l'absence d'étiologie connue ou de cardiopathie préexistante. Nous rapportons l'observation d'une jeune patiente de 31 ans sans antécédents pathologiques particuliers admise pour une poussée d'insuffisance cardiaque gauche 1mois après son accouchement.

    2015-01-01

    Résumé Objectif Aider les médecins de famille à mieux reconnaître la fragilité et ses répercussions sur la prise en charge des patients âgés. Sources des données Une recension a été effectuée dans PubMed-MEDLINE de 1990 à 2013 pour trouver des articles rédigés en anglais exclusivement, à l’aide des groupes suivants de mots clés et d’en-têtes MeSH : frail elderly, frail, frailty; aged, geriatrics, geriatric assessment, health services for the aged; primary health care, community health services et family practice. Message principal La fragilité est fréquente, en particulier chez les personnes âgées atteintes de maladies chroniques complexes comme l’insuffisance cardiaque et la bronchopneumopathie chronique obstructive. De nouvelles données probantes démontrent l’importance de la fragilité comme facteur de prédiction d’issues indésirables chez les personnes plus âgées. Quoiqu’on ne s’entende actuellement pas sur les meilleures façons d’évaluer et de diagnostiquer la fragilité en soins primaires, des marqueurs individuels de la fragilité comme la lenteur de la démarche offrent des moyens pratiques prometteurs de dépister la fragilité. La détection de la fragilité en soins primaires peut offrir la possibilité de retarder la progression de la fragilité au moyen d’interventions proactives comme l’exercice. La reconnaissance de l’existence de la fragilité peut orienter un counseling approprié et la prise de mesures préventives anticipatoires pour les patients lorsqu’on envisage des interventions médicales. Elle peut aussi aider à cerner des problèmes concomitants qui contribuent à la fragilité et l’influencent et à en optimiser la prise en charge. Les recherches futures devraient se pencher sur la détermination de moyens pratiques et efficaces pour évaluer et prendre en charge de manière appropriée ces patients vulnérables au niveau des soins primaires. Conclusion En dépit de son importance

    1983-01-01

    The mink (Mustela vison) is a predatory, semiaquatic mammal that is generally associated with stream and river banks, lake shores, fresh and saltwater marshes, and marine shore habitats (Gerell 1970).  Mink are chiefly nocturnal and remain active throughout the year (Marshall 1936); Gerell 1969; Burgess 1978).  The species is adaptable in its use of habitat, modifying daily habits according to environmental conditions, particularly prey availability (Wise et al. 1981; Linn and Birds 1981; Birks and Linn 1982).  The species is tolerant of human activity and will inhabit suboptimum habitats as long as an adequate food source is available; however, mink will be more mobile and change home ranges more frequently under such conditions (Linn pers. comm.).

    The nesting range of Forster's terns hosts three allopatric breeding populations. The first and most important breeding area, in terms of the number of nes t i ng pairs, includes the western guIf coas t from the Louisiana-Mississippi border to northern Tamaulipas, Mexico (American Ornithologists' Union [AOUJ 1983). In addition, small numbers of Forster's terns have nested in Mobile County, Alabama (Imhof 1976). Although this species has not been recorded nesting in Mississippi (J. Jackson, Mississippi State University, Starkville; pers. comm.), it is observed in the coastal regions of that State every summer, and several thousand nest in adjacent Louisiana (Portnoy 1977; Clapp et ale 1983). The two largest colonies of Forster's terns documented in the literature were both in Louisiana: one of 2,750 pairs in Lake Borgne on the Louisiana-Mississippi border and one of 2,263 pairs in Calcasieu Lake (Portnoy 1977).

    Optimetrics for Precise Navigation will be implemented on existing optical communication links. The ranging and Doppler measurements are conducted over communication data frame and clock. The measurement accuracy is two orders of magnitude better than TDRSS. It also has other advantages of: The high optical carrier frequency enables: (1) Immunity from ionosphere and interplanetary Plasma noise floor, which is a performance limitation for RF tracking; and (2) High antenna gain reduces terminal size and volume, enables high precision tracking in Cubesat, and in deep space smallsat. High Optical Pointing Precision provides: (a) spacecraft orientation, (b) Minimal additional hardware to implement Precise Optimetrics over optical comm link; and (c) Continuous optical carrier phase measurement will enable the system presented here to accept future optical frequency standard with much higher clock accuracy.

  11. Multi-GPU-based Swendsen-Wang multi-cluster algorithm for the simulation of two-dimensional q-state Potts model

    2013-01-01

    We present multiple GPU computing with the common unified device architecture (CUDA) for the Swendsen-Wang multi-cluster algorithm of two-dimensional (2D) q-state Potts model. Extending our algorithm for single GPU computing [Y. Komura, Y. Okabe, GPU-based Swendsen-Wang multi-cluster algorithm for the simulation of two-dimensional classical spin systems, Comput. Phys. Comm. 183 (2012) 1155-1161], we realize the GPU computation of the Swendsen-Wang multi-cluster algorithm for multiple GPUs. We implement our code on the large-scale open science supercomputer TSUBAME 2.0, and test the performance and the scalability of the simulation of the 2D Potts model. The performance on Tesla M2050 using 256 GPUs is obtained as 37.3 spin flips per a nano second for the q=2 Potts model (Ising model) at the critical temperature with the linear system size L=65536.

  12. Efficiency and Large Deviations in Time-Asymmetric Stochastic Heat Engines

    In a stochastic heat engine driven by a cyclic non-equilibrium protocol, fluctuations in work and heat give rise to a fluctuating efficiency. Using computer simulations and tools from large deviation theory, we have examined these fluctuations in detail for a model two-state engine. We find in general that the form of efficiency probability distributions is similar to those described by Verley et al. [2014 Nat Comm, 5 4721], in particular featuring a local minimum in the long-time limit. In contrast to the time-symmetric engine protocols studied previously, however, this minimum need not occur at the value characteristic of a reversible Carnot engine. Furthermore, while the local minimum may reside at the global minimum of a large deviation rate function, it does not generally correspond to the least likely efficiency measured over finite time.

    Récemment nous avons débuté des séries d'expériences sur l'interaction d'impulsions intenses VUV avec les solides luminescents. Le but principal en est l'étude des mécanismes d'interaction et de transfert d'énergie entre les excitations électroniques dans les solides à large bande interdite. L'application directe de ces études sera le développement de matériaux et de méthodes de métrologie pour les faisceaux UVX intenses. Nous présentons les résultats obtenus pour CdWO{4} qui montrent que ce cristal pourra servir comme un scintillateur pour le rayonnement VUV intense.

    2010-01-01

    This slide presentation reviews the mission of the Space Communications and Navigation (SCaN) Office with particular emphasis on opportunities for technology development with SBIR companies. The SCaN office manages NASA's space communications and navigation networks: the Near Earth Network (NEN), the Space Network (SN), and the Deep Space Network (DSN). The SCaN networks nodes are shown on a world wide map and the networks are described. Two types of technologies are described: Pull technology, and Push technologies. A listing of technology themes is presented, with a discussion on Software defined Radios, Optical Communications Technology, and Lunar Lasercom Space Terminal (LLST). Other technologies that are being investigated are some Game Changing Technologies (GCT) i.e., technologies that offer the potential for improving comm. or nav. performance to the point that radical new mission objectives are possible, such as Superconducting Quantum Interference Filters, Silicon Nanowire Optical Detectors, and Auto-Configuring Cognitive Communications

  17. On the phenomenology of tilted domains in lamellar eutectic growth

    NASA Astrophysics Data System (ADS)

    Caroli, B.; Caroli, C.; Fauve, S.

    1992-03-01

    We show that, due to the coupling between tilt (amplitude of the antisymmetric part of the font profile) and phase dynamics, the phenomenology of tilt domains of finite width proposed by Coullet et al. within the assumption of a subcritical homogeneous tilt bifurcation retains the same qualitative features when this bifurcation is direct, as is the case for lamellar eutectics. Nous montrons que, du fait du couplage entre les dynamiques d'inclinaison (amplitude de la partie impaire du profil de front) et de phase, la phénoménologie des domaines d'inclinaison de largeur finie proposée par Coullet et al. pour le cas d'une bifurcation d'inclinaison homogène sous critique garde les mêmes caractéristiques qualitatives quand cette bifurcation est directe, comme c'est le cas pour la croissance eutectique lamellaire.

  19. Stability of undercompressive shock profiles

    NASA Astrophysics Data System (ADS)

    Howard, Peter; Zumbrun, Kevin

    Using a simplified pointwise iteration scheme, we establish nonlinear phase-asymptotic orbital stability of large-amplitude Lax, undercompressive, overcompressive, and mixed under-overcompressive type shock profiles of strictly parabolic systems of conservation laws with respect to initial perturbations |u(x)|⩽E(1 in C, E sufficiently small, under the necessary conditions of spectral and hyperbolic stability together with transversality of the connecting profile. This completes the program initiated by Zumbrun and Howard in [K. Zumbrun, P. Howard, Pointwise semigroup methods and stability of viscous shock waves, Indiana Univ. Math. J. 47 (4) (1998) 741-871], extending to the general undercompressive case results obtained for Lax and overcompressive shock profiles in [A. Szepessy, Z. Xin, Nonlinear stability of viscous shock waves, Arch. Ration. Mech. Anal. 122 (1993) 53-103; T.-P. Liu, Pointwise convergence to shock waves for viscous conservation laws, Comm. Pure Appl.

  20. Locomotion of a microorganism in weakly viscoelastic liquids

    In the present work we study the motion of microorganisms swimming by an axisymmetric distribution of surface tangential velocity in a weakly viscoelastic fluid. The second-order fluid constitutive equation is used to model the suspending fluid, while the well-known "squirmer model" [M. J. Lighthill, Comm. Pure Appl. Math. 5, 109 (1952), 10.1002/cpa.3160050201; J. R. Blake, J. Fluid Mech. 46, 199 (1971), 10.1017/S002211207100048X] is employed to describe the organism propulsion mechanism. A regular perturbation expansion up to first order in the Deborah number is performed, and the generalized reciprocity theorem from Stokes flow theory is then used, to derive analytical formulas for the squirmer velocity. Results show that "neutral" squirmers are unaffected by viscoelasticity, whereas "pullers" and "pushers" are slowed down and hastened, respectively. The power dissipated by the swimming microorganism and the "swimming efficiency" are also analytically quantified.
