Supervision de l'action et optimisation des comportements : Etudes électrophysiologiques et IRMf

Les mecanismes cerebraux impliques dans l'optimisation des comportements sont encore mal connus. Nous avons cherche a preciser leurs fonctionnement a travers des etudes EEG et IRMf dans des tâches de temps de reaction manipulant la compatibilite Stimulus-Reponse. Plusieurs arguments issus de methodologies differentes nous ont permis de preciser le role de la Negativite d'Erreur (Ne), une onde EEG initialement rapportee dans les erreur, et qui atteint son maximum juste apres la reponse. Initialement attribuee a la detection de l'erreur, cette activite, localisee dans la zone cingulaire rostrale, pourrait avoir pour role d'evaluer la performance en cours d'essai dans le but de rattraper l'erreur. Nous nous sommes interesses aux mecanismes impliques de la selection de la reponse. La N-40, enregistree au dessus de l'aire motrice supplementaire, incarnerait l'association stimulus-reponse alors que les cortex moteurs seraient le lieu de la mise en place d'un mecanisme de prevention de l'erreur implemente par une elevation du seuil de declenchement des reponses en presence d'un risque d'erreur. Enfin dans une etude IRMf, nous avons montre que les ajustements comportementaux suite a un essai incompatible prenaient la forme d'une augmentation du traitement perceptif des caracteristiques pertinentes de la tâche et d'une diminution du traitement des caracteristiques non-pertinentes. Nous avons precise le role fonctionnel de la \Ne ainsi que les operations mises en jeu lors de la mise en place des ajustements comportementaux. Ces resultats suggerent egalement l'existence de mecanismes capables de detecter en ligne un risque d'erreur dans le but de prevenir une erreur en cours d'essai.
Multi-objective ant colony optimisation-based routing in WSNs

Wireless sensor networks (WSNs) are expected to play an important role for sensing applications in the near future. A simple but robust way for the routing in WSNs is the use of multi-objective ant colony optimisation (MOACO) algorithms, biologically-inspired algorithms that are capable of considering multiple objectives in the optimisation process at the same time. In this paper MARFWSN, a multi-objective ant colony optimisation routing framework for WSNs, is proposed that allows to use MOACO algorithms for the routing in WSNs. Due to its modulised structure different MOACO algorithms can be simply docked using the provided interface. Additionally, to mitigate insider attacks, trust is considered as one of the objectives in the route optimisation process.
Attribute based image retrieval and hypergraph learning based image search reranking

Image search re-ranking is a powerful method to enhanced result we get from text-based search. We get noisy data from text-based search. The objective of this work is to enhance the system which re-arrange the images which user get from simple text-based search in such a way that, resultant image set contains relevant images. On this challenge, this paper proposed to use the semantic attributes for re-ranking. Every image describe through specific attribute. These attributes have already ready classifiers. User will gets responses from these classifiers on the basis of attribute. Every image in responses have relation with each other by mean of its attribute. This relation supposed to be shown by hypergraph. Images in the hypergraph ranked as per their ranking score. Ranking score represents similarity factor with respect to common attribute of images in hypergraph. This paper use attribute learning of images and hypergraph formation method to get valuable result.
SYNTHESIS & INTEGRATION Applying resilience thinking to production ecosystems

Production ecosystems typically have a high dependence on supporting and regulating ecosystem services and while they have thus far managed to sustain production, this has often been at the cost of externalities imposed on other systems and locations. One of the largest challenges facing humanity is to secure the production of food and fiber while avoiding long-term negative impacts on ecosystems and the range of services that they provide. Resilience has been used as a framework for understanding sustainability challenges in a range of ecosystem types, but has not been systematically applied across the range of systems specifically used for the production of food and fiber in terrestrial, freshwater, and marine environments. This paper applied a resilience lens to production ecosystems in which anthropogenic inputs play varying roles in determining system dynamics and outputs. We argue that the traditional resilience framework requires important additions when applied to production systems. We show how sustained anthropogenic inputs of external resources can lead to a ‘‘coercion’’ of resilience and describe how the global interconnectedness of many production systems can camouflage signals indicating
Dados preliminares sobre a germinação de sementes de Ucuuba.

A ucuuba (Virola surinamensis (Rol.) Warb. ) é uma espécie nativa dos igapós e várzeas do Amazonas e Pará, pertencente à família Myristicaceae, com larga distribuição geográfica do Maranhão a Pernambuco, ocorrendo ainda nas Antilhas, Guianas e América Central (RIZZINI, 1971). Com demanda crescente a partir da década de 60, essa espécie representa, atualmente, 60% das exportações, sendo a madeira preferida para a fabricação de compensados (PANDOLFO, 1978). Além disto, ela é utilizada também em laminados, embalagens, artigos de esportes, brinquedos, mobiliário, lápis, palitos, bobinas e carretéis (SUDAM, 1981). Além de diversas aplicações medicinais de uso popular, BARATA & BAKER (1973) atribuem ao estrato hexânico das folhas de V. surinamensis uma ação protetora contra a infecção por Schistosoma mansoni.
Requirement of a Mitogen-Activated Protein Kinase for Appressorium Formation and Penetration of Insect Cuticle by the Entomopathogenic Fungus Beauveria bassiana

ABSTRACT Beauveria bassiana is an important insect-pathogenic fungus that invades insects by direct penetration of the host cuticle. To delineate the molecular mechanisms involved in fungal infection, a mitogen-activated protein kinase (MAPK) gene, Bbmpk1, which encodes a YERK1 family MAPK was isolated and characterized. Targeted gene disruption of Bbmpk1 resulted in a complete loss of virulence when applied topically to host insects but did not affect growth of the fungus when conidia were injected directly into the hemocoel. Hyphae of the mutant strain growing in the insect hemocoel were unable to penetrate the cuticle growing outwards and consequently failed to sporulate on the cadaver surface. These data suggest that BbMPK1 is essential for penetration of the insect cuticle both from the outside and from the inside-out in order to escape and disperse from the host. Inactivation of BbMPK1 also caused a significant decrease in fungal adhesion to insect cuticles and eliminated their ability to form appressoria. In order to identify downstream genes regulated by BbMPK1, a suppressive subtractive hybridization (SSH) library was generated comparing mutant and wild-type transcripts isolated during appressorium formation. Thirty-one genes screened from the SSH library were determined to be expressed in the wild-type strain but either significantly reduced or not expressed in the mutant. Ten genes showed high or medium similarity to known protein encoding genes, including proteins involved in cell surface hydrophobicity, lipid metabolism, microtubule dynamics, mitochondrial electron transport, chromatin remodeling, transcription, rRNA processing, small nucleolar RNA accumulation, oxidation of aldehydes, translation, and likely other cellular processes.
Psychanalyse et normativité : la question cisgenre

Les auteurs proposent une analyse des rapports entre la psychanalyse et la norme a partir d’un examen critique du statut donne a la transsexualite a l’interieur du savoir analytique. Methodologiquement, on part de la definition de « cisgenre » – c’est-a-dire l’oppose de « transsexuel » –, non comme synonyme de « normal », mais comme construction d’une identite et d’un rapport au corps sexue autant problematique que celle suppose chez les sujets trans. Ainsi, a partir des reflexions de Judith Butler, de Georges Canguilhem, de Sigmund Freud et de Jacques Lacan on travaille l’hypothese selon laquelle il n’y a pas une normalite possible d’identite sexuelle. Etant donne que tout etre parlant jouit d’un corps libidinal, cependant soumis au cadre normatif du genre, il n’existerait jamais de coincidence entre le reel de la pulsion, l’image speculaire unifiee du moi et les signifiants qui marquent le corps sexue – que ce soit chez les sujets cis, ou chez les sujets trans.
PEDESTRIAN PREFERENCES WITH RESPECT TO ROUNDABOUTS – A VIDEO-BASED 1 STATED PREFERENCE SURVEY 2 Paper 14-5528 3 4

44 Attention to user behavior and preferences has been a helpful tool in improving road safety and 45 accident prevention in recent years. At the same time, there remain some important areas of road 46 safety and accident prevention for which user preferences have not been explored. For instance, 47 so far, road safety research has not addressed pedestrian and vulnerable user preferences with 48 respect to roundabouts, despite the increasing construction of these intersections around the 49 world. The present research stems from the fact that studies related to roundabout safety have 50 typically put drivers in a privileged position, while generally overlooking the importance of 51 safety as it relates to vulnerable users, especially pedestrians. Moreover, it handles this particular 52 issue through an approach that has not been used so far: the Stated Preference (SP) survey. 53 As such, this paper describes the justification for, the methodology, the analysis and 54 conclusions of a SP survey designed to obtain pedestrian and vulnerable user preferences with 55 respect to roundabout facilities in Quebec. In addition to the fact that an SP survey has not been 56 used in this context before, another innovative facet of the work lies in the use of traffic micro57 simulation software to create videos that serve as alternatives in Choice Tasks in the SP survey. 58 The study finds that pedestrian preferences for roundabouts are affected by: the presence of 59 pedestrian crossings (and their location relative to the roundabout), signage and pedestrian 60 islands, as well as the number of traffic lanes they must cross. In addition to these design 61 features, pedestrian preferences for roundabouts are also affected by the speed and volume of 62 traffic – something we were able to evaluate thanks to the use of traffic simulation videos. 63 64
Serious complications with talc slurry pleurodesis

Objective: Talc is a highly efficacious and commonly employed agent for chemical pleurodesis, which has generally been felt to be well tolerated. However, increasing reports of adult respiratory distress syndrome (ARDS) have heightened safety concerns. A recent case of ARDS prompted us to review our experience with talc pleurodesis.
A systematic review of the effectiveness of school‐based obesity prevention programmes for First Nations, Inuit and Métis youth in Canada

First Nations, Inuit and Métis (FNIM) youth are disproportionately affected by obesity and represent known a high‐risk group in Canada. School‐based prevention programmes may have the potential to effectively influence obesity‐related health behaviours (i.e. healthy eating and physical activity) among this population. We conducted a systematic review of nine electronic databases (2003–2014) to identify studies that describe school‐based programmes that have been developed to improve obesity‐related health behaviours and outcomes among FNIM youth in Canada. The objectives of this review were to identify and evaluate the effectiveness of these programmes and assess the strength of the methodologies used to evaluate them. Fifteen studies, representing seven distinct interventions, met our inclusion criteria. The majority of these programmes did not result in significant improvements in outcomes related to obesity, healthy eating, or physical activity among FNIM youth. The studies varied in design rigour and use of evaluation activities. The lack of literature on effective school‐based programmes for FNIM youth in Canada that target obesity‐related outcomes highlights a priority area for future intervention development, evaluation and dissemination within the peer‐reviewed literature. Further research is needed on interventions involving Métis and Inuit youth, secondary school‐aged FNIM youth and FNIM youth living in urban settings.
Short-time failure of metal interconnect caused by current pulses

It is pointed out that voltage programmable link (VPL) technologies impose a new criterion on the reliability of metal interconnect. Lines of metallization must support the full programming current, which can be many times larger than the signal level current, for very short periods of time. For a sufficiently short high-current pulse, the wire, encapsulated in oxide, will not reach thermal equilibrium and the current-induced heating can be modeled as being adiabatic. Energy conservation predicts a relationship between maximum current density that can be carried by a wire before it fuses, and the pulse duration time, J/sup 2/t=10/sup 8/ A/sup 2/-s/cm/sup 4/. This relationship is based on a temperature rise in the metal line at failure of theta /sub f/*=300 degrees C. The time required for the metal to reach thermal equilibrium at a given current density is shown to be proportional to the square of the oxide thickness. These predictions are experimentally verified with layered AlSi/Ti metallization on thermal oxide on silicon substrates. <<ETX>>
Conception de circuits RF en CMOS SOI pour modules d'antenne reconfigurables

Dans le contexte des applications mobiles, les contraintes de conception des chaines d’emission toujours plus performantes et de taille reduite demandent de compenser la forte sensibilite des caracteristiques des antennes a leur environnement. En particulier, il est necessaire de maitriser l’impedance de l’antenne pour optimiser l’efficacite energetique de la chaine de transmission. Or, les solutions actuelles se montrent encombrantes. Dans cette these, plusieurs pistes basees sur l’implementation de condensateurs variables ont ete etudiees et ont conduit a la realisation et la caracterisation de nouveaux dispositifs RF integres a meme de participer a cet effort. Apres une presentation du contexte et de l’etat de l’art, nous proposons une etude de condensateurs variables bases sur la technique des capacites commutees. L’etude a permis la realisation de deux condensateurs variables en technologie CMOS SOI 130 nm pour des applications d’adaptation d’impedance et d’antenne agile en frequence. Un premier demonstrateur d’antenne fente agile en frequence visant les bandes LTE situees entre 500 MHz et 1 GHz et utilisant ce type de condensateur a ensuite ete realise puis valide. Un systeme d’accord permettant de corriger les desadaptations d’antenne a ensuite ete etudie et a donne lieu a la realisation de deux circuits integres en technologie CMOS SOI 130 nm. Le premier circuit est un detecteur d’impedance capable de fonctionner sur une gamme de puissance etendue de 0-40 dBm pour une plage de frequences de 600 MHz-2,5 GHz. Le deuxieme circuit integre une version amelioree du detecteur avec un circuit d’adaptation variable autorisant la realisation d’un systeme d’accord d’antenne autonome et compact representant une avancee importante par rapport a l’etat de l’art.
Ultra-wideband CPW six-port circuits based on multilayer technology

A new multilayer six-port circuit using an ultra-wideband directional coupler is presented and implemented. The use of multilayer technology allows having a compact circuit and very large bandwidth. To validate this concept, a six-port prototype was fabricated and measured. Simulation and measurement results show the proposed six-port circuit can easily operate over an ultra-wide band from 4 to 7 GHz.
First environmental sample containing plasmid‐mediated colistin‐resistant ESBL‐producing Escherichia coli detected in Norway

We hereby report the detection of the plasmid borne mcr‐1 gene conferring colistin resistance in an extended‐spectrum β‐lactamase (ESBL) producing Escherichia coli ST10 strain retrieved from seawater at a public beach in Norway. The sample was collected in September 2010 and was investigated by whole‐genome sequencing in 2016. This report illustrates that E. coli strains carrying plasmid‐mediated colistin resistance genes have also reached areas where this drug is hardly used at all. Surveillance of colistin resistance in environmental, veterinary, and human strains is warranted also in countries where colistin resistance is rare in clinical settings.
DSP for Coherent Single-Carrier Receivers

In this paper, we outline the design of signal processing (DSP) algorithms with blind estimation for 100-G coherent optical polarization-diversity receivers in single-carrier systems. As main degrading optical propagation effects, we considered chromatic dispersion (CD), polarization-mode dispersion (PMD), polarization-dependent loss (PDL), and cross-phase modulation (XPM). In the context of this work, we developed algorithms to increase the robustness of the single DSP receiver modules against the aforesaid propagation effects. In particular, we first present a new and fast algorithm to perform blind adaptive CD compensation through frequency-domain equalization. This low complexity equalizer component inherits a highly precise estimation of residual dispersion independent from previous or subsequent blocks. Next, we introduce an original dispersion-tolerant timing recovery and illustrate the derivation of blind polarization demultiplexing, capable to operate also in condition of high PDL. At last, we propose an XPM-mitigating carrier phase recovery as an extension of the standard Viterbi-Viterbi algorithm.
Approche oecuménique au problème du codage des structures linguistiques

En etudiant les principaux projets de bases lexicales en Europe ou au Japon, on se rend compte de l'importance croissante des recherches sur le domaine. Par contre, on remarque aussi la quasi absence de solutions generiques au probleme de la definition des structures linguistiques des elements d'une base lexicale. Certes, le projet Multilex et le systeme "Le Lexicaliste" offrent au linguiste un langage pour definir ses structures linguistiques. Mais ces langages imposent une structure logique avec laquelle le linguiste doit coder ses structures linguistiques. Nous proposons une approche œcumenique au probleme de la definition des structures linguistiques d'un dictionnaire. Cette approche passe par un langage specialise qui permet l'utilisation de structures logiques differentes (arbres, graphes, automates, ensembles, listes, arcs, .) dans les structures linguistiques du lexique. Ainsi, le linguiste peut choisir la structure logique la plus adequate pour coder sa theorie linguistique. Il peut de plus melanger differentes structures logiques dans une meme structure linguistique. Nous donnons dans cet article un apercu du langage specialise utilise dans le projet NADIA. Nous justifions enfin l'interet du melange de differentes structures logiques dans une meme structure linguistique. Pour cela, nous proposons un codage assez naturel d'une entree du Dictionnaire Explicatif et Combinatoire (DEC) du francais contemporain par Igor Mel' c uk.
IMPORTANCE OF SECONDARY STRUCTURE ELEMENTS FOR PREDICTION OF GO ANNOTATIONS

Predicted or actual protein secondary structure, in addition to amino acid sequence, is often used for fold recognition and function prediction. Different kinds of secondary structure elements could be predicted with different accuracy by different prediction methods and this could affect the fold or function prediction performance. In this study, contribution of amino acid sequence residues belonging to different types of secondary structure elements (H: alpha helix, E: beta sheet, L: loop) for protein function prediction is investigated. Smith-Waterman alignment similarity scores between amino acid sequences belonging to 6 different sets of secondary structure elements, namely, HEL, HE, HL, H, E and L, are computed. Using these alignment scores, protein function prediction is performed. On a function prediction data set, consisting of 27 Gene Ontology (GO) classes and 4498 sequences, it is found out that using the whole amino acid sequence results in the best performance. Using H and L regions together results almost as well performance as HEL. E regions alone are the least significant in function prediction.
Cytokine induction and exploitation in schistosome infections

Schistosome parasites, despite being multicellular organisms several millimetres in length, can survive in the bloodstream of mammalian hosts for decades. The remarkable and complex adaptation exemplified in the host–parasite relationship in schistosomiasis may include not only immune evasion by the parasite, but also immune exploitation. While the developmental and adult stages of the parasite are by and large invisible to the immune response, the parasite egg induces a granulomatous reaction which not only protects the host from a diffusible parasite toxin, but also is required for normal transmission of parasite eggs from the host to the external environment. Other possible mechanisms of immune exploitation by schistosomes are discussed including skewing of cytokine responses, effects of cytokines on worm fecundity, exploitation of endothelial cell adherence, and induction of IgE.
Hereditary primary reading epilepsy

EPILEPSY PROVOKED by reading was described by Bickford and co-workers1 as a new syndrome, existing in both primary and secondary forms. The latter was a far-from-stereotyped condition in which fits provoked by reading, but sometimes by other visual stimuli, appeared to be secondary to a focal cerebral lesion. In the primary form, on the other hand, no evidence of a focal lesion could be found. A highly characteristic feature was a curious jerking of the jaw, provoked by reading and occurring either in isolation or preceding major fits. It has not always been possible to draw such a sharp distinction from the data presented in subsequent case reports. But the concept of a primary form, in which this unusual type of epilepsy is the only abnormality, would be greatly strengthened by any evidence of a genetic basis.
Genotypic Diversity of Haemophilus parasuis Field Strains

ABSTRACT Haemophilus parasuis is the cause of Glässer's disease and other clinical disorders in pigs. It can also be isolated from the upper respiratory tracts of healthy pigs, and isolates can have significant differences in virulence. In this work, a partial sequence from the 60-kDa heat shock protein (Hsp60) gene was assessed as an epidemiological marker. We analyzed partial sequences of hsp60 and 16S rRNA genes from 103 strains of H. parasuis and other related species to obtain a better classification of the strains and examine the correlation with virulence. The results were compared with those obtained by enterobacterial repetitive intergenic consensus PCR. Our results showed that hsp60 is a reliable marker for epidemiological studies of H. parasuis and that the analysis of its sequence is a better approach than fingerprinting methods. Furthermore, the analysis of the hsp60 and 16S rRNA gene sequences revealed the presence of a separate lineage of virulent strains and indicated the occurrence of lateral gene transfer among H. parasuis and Actinobacillus strains.
