Taking as starting point the experience of the artists of the Indian diaspora in England, the article suggests rethinking the role and the meaning of the term hybrid in the field of dance and of contemporary creation. Applied without distinction to any kind of multicultural artistic creation, this term conveys a plurality of senses, sometimes contradictory. Notions of contemporary biology will supply the theoretical tools for an analysis of the hybrid processes of creation, allowing a diversified reading of experiences often perceived as homogeneous., Prenant comme point de départ l’expérience des artistes de la diaspora indienne en Angleterre, l’article propose de repenser le rôle et la signification du terme hybride dans le champ de la danse et de la création contemporaine. Appliqué sans distinction à toute sorte de création artistique à caractère multiculturel, ce terme véhicule une pluralité de sens parfois contradictoires. Le recours à des notions de biologie contemporaine fournira les outils théoriques nécessaires à une analyse des processus de création hybrides, permettant une lecture diversifiée d’expériences souvent perçues comme homogènes., Ao tomar como ponto de partida a experiência dos artistas da diáspora indiana na Inglaterra, este artigo propõe repensar o papel e o significado do termo híbrido no campo da dança e na criação contemporânea. Aplicado sem distinção a todo tipo de criação artística de caráter multicultural, esse termo veicula uma pluralidade de sentidos, às vezes, contraditórios. O recurso a noções da biologia contemporânea fornecerá as ferramentas necessárias a uma análise dos processos híbridos de criação, permitindo uma leitura diversificada de experiências muitas vezes percebidas como homogêneas.

International audience; At the exploration scale, the simulation of seismic wave propagation in the subsurface requires using absorbing boundary conditions. For the last twenty years, the method of choice has been the Perfectly Matched Layer (PML) method. PML are easy to implement and remarkably accurate. However, in certain situations such as the simulation of seismic waves in anisotropic media, the PML method becomes amplifying. We present here an alternative layer method, the SMART method. This method is based on a selective damping strategy. From an eigenvalue analysis of the matrices defining the hyperbolic system, the outgoing components of the wavefield associated with P- and S-wave velocities are damped. The SMART layer has two advantages over the PML. First, the dissipation is ensured for elasto-dynamic equations in isotropic and anisotropic media (no amplification). Second, the method yields a new strategy to prevent from the generation of non physical S-waves in acoustic transverse isotropic modeling. The SMART layer method is not perfectly matched, therefore less accurate than the PML. However our numerical experiments show that the accuracy of the PML can be reached provided an increase of the layer width. The additional computational cost associated with this increase of the layer size is compensated by the fact that the SMART method is less expensive: only a zero-order term is added to the initial system of equations, no additional variables are required.

For over 40 years, it is common knowledge that industrial society has to reduce its energy consumption. Most of people are now aware that this change is necessary. However, commitment to action is still difficult and there is substantial work to be done. Attention has turned to Human and Social Sciences, as a deeper understanding of behaviors' determinant and use of influence principles could help to speed up behavior changes. New technical devices combining game design, interaction techniques and persuasion have emerged but the field is still in its infancy. This article gives a glimpse at a toolbox helping to design and evaluate interactive persuasive devices and discuss five main challenges. This work is extended by two others papers: Negri et Senach (2015b) provide a first grid of persuasion principles and in Senach et Negri (2015c), these grid have been applied to assess the persuasive properties of an energy challenge within a company. Depuis plus de 40 ans, il est de notoriété publique qu'il est nécessaire de modifier les comportements de consommation énergétique dans les sociétés industrielles. Globalement, la prise de conscience par le grand public de la gravité des questions d'écologie est maintenant acquise. Et pourtant, le passage à l’acte est encore difficile et les gisements d'économies restent considérables. La lenteur des évolutions comportementales a conduit à rechercher du côté des Sciences Humaines et Sociales des modèles permettant une compréhension en profondeur des déterminants des comportements et à identifier des principes d'influence (crédibilité, expertise, réciprocité, etc.). L'implémentation de ces principes dans des dispositifs interactifs est une solution qui pourrait accompagner les changements de comportements ; ces nouveaux systèmes, associant le plaisir du jeu et les techniques de persuasion, baptisés ici « systèmes ludo-persuasifs » (SLP) pourraient être de bons candidats pour aider à l'adoption d'éco-gestes. Mais, l'utilisation des technologies interactives pour la persuasion est encore trop récente pour qu'une véritable ingénierie se soit développée. Dans le travail présenté ci-dessous, nous proposons l'élaboration d'une « boîte à outils » ludo-persuasive en discutant les défis qui doivent être relevés. Cet article est prolongé par deux travaux complémentaires : Negri et Senach (2015b) proposent une structuration de principes persuasifs et ils appliquent ensuite cette grille pour analyser a posteriori les caractéristiques ludo-persuasives d'un challenge énergétique conduit en entreprise (Senach & Negri, 2015c)

St-Jean-de-Luz/Ciboure bay is protected by three breakwaters constructed in masonry on rubble mound foundation with armor units of 50 t. Breaking waves inflict significant damages: breaches in the foundation, cracks, fractures and masonry torn away. Numerical and experimental hydrodynamic studies have been realized to better understand the conditions of maintenance of the breakwaters. Wave flume tests have been conducted to evaluate loads due to breaking waves. To separate hydrodynamic forces (Froude similarity) from hydrodynamic shocks (Cauchy similarity), an extrapolation law was defined using the Bagnold’s model. Its parameters have been calibrated with results of model tests on two scales. The method is presented and results are discussed.

Depression is the most common of psychiatric illnesses. The design of effective treatments for this disorder is a challenging process. Recently, the two-pore domain potassium channel TREK-1 has been identified as a new target in depression, and its antagonists might become effective antidepressants. Deletion of TREK-1 gene results in a depression-resistant phenotype that mimics antidepressant treatments. Here, we validate the fast antidepressant effects of spadin, a secreted peptide derived from the propeptide generated by the maturation of the sortilin receptor and acting through TREK-1 inhibition.

The purpose of the mini-workshop is to bring into the same place different mathematical communities that study constructive homological al- gebra and are motivated by different applications (e.g., constructive algebra, symbolic computation, proof theory, algebraic topology, mathematical sys- tems theory, D-modules, dynamical systems theory) so that they can share their results, techniques, softwares and experiences. Through the develop- ment of a unified terminology, common mathematical problems, which natu- rally appear when making homological algebra constructive, were discussed.

Resume : Le gouvernement guineen (Guinee equatoriale) a entrepris de developper ces infrastructures et en particulier au sein de ses nombreuses iles dans le golfe de Guinee. Dans ce contexte, l’ile de Corisco, situee a une vingtaine de kilometres du continent, fait l’objet de la creation d’un port, non pas sur l’ile elle-meme, mais a une certaine distance de celle-ci pour ne pas impacter l’environnement et la stabilite des plages de sable qui entourent l’ile. Le choix a ete fait de creer un ilot de sable servant a abriter un port et de relier cet ilot a l’ile par un wharf. Notre etude a consiste a dimensionner un ouvrage de protection sous la forme d’empilements de GSC remplis de sable actuellement en cours de construction. La forme et la position de l’ilot a ete determine en fonction des contraintes hydrodynamiques et sedimentologiques pour un moindre impact. Cette publication a pour objet de mettre en evidence qu’il est parfaitement envisageable de realiser des digues de protection en geotextile a condition de prendre des precautions dans la conception, le dimensionnement et la construction de l’ouvrage. Mots-cles : Guinee equatoriale, Port, Ile, Sable, Geosynthetique (Geotextile Sand Containers), Houle, Digue, Dimensionnement.

Functional assessments of a person’s ability to perform activities of daily living (ADL) currently involves clinical rating scales. These scales are limited in providing objective and sensitive information. Aim To develop an automated tool for objective and quantitative assessment of functional ability in Alzheimer disease (AD). Methods 16 Patients with mild to moderate AD (age=76.7±4.0, MMSE=20,7±2.0) and 10 age and gender matched healthy controls (HC; age=73.9±4.5, MMSE=28.1±1.3) were evaluated clinically, cognitively, and functionally. Subsequently, each subject was asked to perform a set of daily tasks while monitored by two video cameras. A measure of functional impairment was then computed from quantitative and qualitative parameters collected from video recordings that were first annotated by two clinicians (blind to each other results and the participants’ clinical state). Results The VMS (Video monitoring system) function index (derived from a ratio of efficacy in ADLs) correlated strongly with cognitive results (MMSE, Rho=0.81) as well as with IADL-E scores (Rho=-0.65). Conclusion This study is a successful proof of concept for a novel assessment tool in dementia. The derived VMS function-index may provide a pragmatic, objective and continuous measure of cognitive and functional ability for clinical assessments as well as having a role as an outcome measure in clinical trials. Future research should complete the automation of the method.

Resume : L’objectif du projet OPTIMA-PAC est de developper et de mettre en place un service d’aide a la decision pour l’implantation et le fonctionnement des pompes a chaleur eau de mer (PAC). Ce service dedie aux besoins des industriels et des collectivites territoriales, integre les enjeux environnementaux et d’optimisation energetique. On donne ici un apercu de la strategie de modelisation numerique des conditions meteooceaniques retenue dans le cadre du projet OPTIMA-PAC. Les resultats de ces simulations numeriques sont exploites aussi bien pour la preparation des campagnes de mesures en mer (previsions operationnelles a haute resolution des conditions meteooceaniques) que pour l’evaluation de l’impact environnemental et l’optimisation energetique des PAC (rejeux des conditions meteo-oceanique).

Resume : On observe actuellement une augmentation sensible a l’echelon national et international des ouvrages de protection contre l’erosion marine ayant un caractere de "reversibilite" d’une part et presentant d’autre part un moindre cout par rapport a des techniques de protection classiques en enrochements. Il s’agit dans la plupart des cas d’ouvrages en forme de tubes constitues d’une double enveloppe en geotextile rempli de sable. De longueur et de hauteur variables les tubes sont installes dans les petits fonds en amas ou en couple parallelement a la cote pour provoquer le deferlement des vagues et reduire l’erosion des plages. Cette technique est actuellement tres prisee et de nombreuses applications ont vu le jour au cours de cette decennie : Plage de la Capte a Hyeres ; plage de Young-Jin Beach en Coree du Sud et plus recemment a Moriani plage en Haute Corse et sur la plage de la Croisette a Cannes. Le retour d’experience sur certaines de ces applications est presente dans cet article en particulier la tenue a la mer des ouvrages et leur efficacite contre l’erosion marine.

This paper is aimed at showing the complementarity between Richardson's and Hicks' contributions as regards the sketching out of a proper analytical framework for dynamic analysis. These contributions deal with two essential analytical ingredients that the out-of-equilibrium analysis of processes of economic change calls for: investment, in the sense of construction of productive capacity, and the relations which must be established for construction looked at as a process over time. In particular, light is thrown on the specific co-ordination problem that characterizes a process of economic change; a problem that arises at the junction of two strictly related lags: the phase of construction of productive capacity - which entails sunk costs - and the delay of transmission of information - which implies uncertainty. The analytical framework thus sketched out helps to understand why the economic agents' interaction does not bring about chaotic results, as long as the decision-makers are characterized by roughly stable patterns of behaviour and/or as long as a fair amount of co-ordination takes place, through various forms of cognitive exchange. It helps to show that the adoption of routines, the compliance to rules and customs, communicative action, the sharing of expectations about the behaviour of the system, the search for explicit agreements, are all mechanisms (or strategies) producing some degree of co-ordination, which confer the required order and stability to the environment.

Scalp psoriasis has a considerable impact on the quality of life (QOL) of patients, and most patients are dissatisfied with available treatments. Clobetasol propionate shampoo 0.05% has been shown to be effective and safe for moderate to severe scalp psoriasis. We evaluated the effect of clobetasol propionate shampoo on QOL and the degree of participant satisfaction with the product. Participants received once-daily treatment for up to 4 weeks. Their QOL and degree of satisfaction were evaluated by questionnaires. The mean (standard deviation) Dermatology Life Quality Index (DLQI) score decreased significantly from 7.0 (4.9) at baseline to 3.2 (3.2) at week 4 (P.001). Participants who considered the disease as having a small effect or no effect on their QOL increased from 45.6% at baseline to 81.7% at week 4. Most participants were satisfied with the cosmetic acceptability and the efficacy and safety aspects of the product, considered it better than prior treatments, and would use it again in the future. Therefore, we conclude that treatment with clobetasol propionate shampoo improved the QOL of participants and resulted in high satisfaction.

Resume : La maitrise de la qualite des eaux cotieres et la gestion des pollutions marines grâce a une meilleure connaissance de leur distribution devient depuis quelques annees un enjeu majeur pour les collectivites littorales. L'etude presentee ici consiste a mettre en place des outils de prevision du risque de presence et de derive de macro-dechets ou de macro-zooplancton –comme les meduses– bases sur des previsions meteorologiques et oceaniques operees en temps quasi-reel. Le principe du modele de derive lagrangienne de macro-dechets sera d’abord presente. Nous nous interesserons ensuite a la methode utilisee pour la prevision de presence de meduses a partir des donnees environnementales et in situ disponibles. Pour la mise en commun des observations de meduses sur le littoral francais en Mediterranee, un site internet ouvert a tous a ete mis en ligne a l’adresse suivante : http://meduse.acri.fr

Resume : Dans le cadre d’une volonte affirmee de gestion de son littoral, la Principaute de Monaco a mis en œuvre une demarche holistique et durable de la connaissance de son milieu marin sur la base de conseils d’experts, de campagnes de mesures in situ et d’outils de modelisation dont l’ensemble presente un niveau rarement atteint aujourd’hui dans ce domaine. Nous presentons dans cet article la synthese des connaissances a fin 2006 et les outils operationnels mis en œuvre. L’objet est de pouvoir ainsi quantifier et maitriser a long terme les consequences d’un projet d’amenagement cotier ou marin. Cette demarche continue a ce jour avec pour objectif de maitriser aussi les consequences des phases travaux sur l’environnement.

RESUME. — L’article tente de montrer la necessite de descriptions analytiques de la monnaie comprise comme un objet structurellement implexe. Il recuse les approches globalisantes des « critiques » de l’argent qui manquent de ce soin analytique. Il se concentre sur un eclairage structurel de la notion de medium explicitant le fait que la complexite operatoire du medium depasse toujours la capacite de maitrise de la complexite de celui qui l’a institue. En constrastant les ontologies respectives du medium (comme inter-esse) et de la chose (comme esse), il eclaire la circulation du medium monetaire dans ses moments structuraux. Il ebauche en conclusion une indication des limites posees a la dynamique circulatoire de la monnaie par l’irreductibilite d’un « temps symbiotique » qu’aucun processus social ne peut eluder.

We consider the problem of how a geostationary satellite should assign bandwidth to several service providers (operators) so as to meet some minimum requirements, on one hand, and to perform the allocation in a fair way, on the other hand. In the paper, we firstly address practical issues (such as integrity constraints), whereafter we provide a computational method for obtaining an optimal fair allocation in polynomial time taking the practical issues into account.
