The Imager for Magnetopause-to-Aurora Global Exploration ( IMAGE) spacecraft obtained the first global images of the proton aurora. One of the discoveries from these images was a region of proton precipitation equatorward of the nominal auroral oval. This precipitation can be observed for similar to10 min immediately following a large solar wind pressure pulse. Various mechanisms have been proposed for producing this precipitation. This study focuses on one of the proposed mechanisms, the scattering and precipitation of protons due to interaction with electromagnetic ion cyclotron (EMIC) waves. Using data from the IMAGE spacecraft FUV and EUV imagers, in situ ring current data from the Los Alamos geosynchronous spacecraft, and in situ solar wind data from the ACE spacecraft, two features of the precipitation, the local time occurrence and limited latitudinal extent, are explained. The local time occurrence of the precipitation is correlated with the orientation of the pressure pulse front in the solar wind. The limited latitudinal extent of the emissions appears to be related to the interaction between the hot ring current protons and the cold plasmaspheric ions that gives rise to EMIC wave growth.

This paper aims at presenting a general versatile time integration scheme applicable to anisotropic damage coupled to elastoplasticity, considering any damage rate and isotropic hardening formulations. For this purpose a staggered time integration scheme in a finite strain framework is presented, together with an analytical consistent tangent operator. The only restrictive hypothesis is to work with an undamaged isotropic material, assumed here to follow a J2 plasticity model. The only anisotropy considered is thus a damage-induced anisotropy. The possibility to couple any damage rate law with the present algorithm is illustrated with a classical ductile damage model for aluminium, and a biological damage-like application. The later proposes an original bone remodelling law coupled to trabecular bone plasticity for the simulation of orthodontic tooth movements. All the developments have been considered in the framework of the implicit non-linear finite element code Metafor (developed at the LTAS/MN2L, University of Liège, Belgium - www.metafor.ltas.ulg.ac.be).

A novel and generic approach for image classification is presented. The method operates directly on pixel values and does not require feature extraction. It combines a simple local sub-window extraction technique with induction of ensembles of extremely randomized decision trees. We report results on four well known and publicly available datasets corresponding to representative applications of image classification problems: handwritten digits (MNIST), faces (ORL), 3D objects (COIL-100), and textures (OUTEX). A comparison with studies from the computer vision literature shows that our method is competitive with the state of the art, an interesting result considering its generality and conceptual simplicity. Further experiments are carried out on the COIL-100 dataset to evaluate the robustness of the learned models to rotation, scaling, or occlusion of test images. These preliminary results are very encouraging [less ▲]

This paper proves the practicality of an iterative algorithm for solving realistic large-scale SCOPF problems. This algorithm is based on the combination of a contingency filtering scheme, used to identify the binding contingencies at the optimum, and a network compression method, used to reduce the complexity of the post-contingency models included in the SCOPF formulation. We show that by combining these two complementary ideas, it is possible to solve in a reasonable time SCOPF problems on large power system models with a large number of contingencies. Unlike most results reported for large-scale SCOPF problems, our algorithm uses a non-linear AC network model in both pre-contingency and post-contingency states, optimizes both active/reactive powers flows jointly, and treats the discrete variables. The proposed algorithm is implemented with state-of-the-art solvers and applied to two systems: a national grid with 2563 buses and 1297 contingencies, and a model of the European transmission network with 9241 buses and 12000 contingencies.

The grafting of poly-N-succinimidyl acrylate from scanning probe microscopy tips is shown to be a robust platform for the very easy elaboration of versatile probes with sensor capabilities and tunable properties. The modified tips can be easily postfunctionalized for single-molecule recognition of host-guest and ligand-receptor systems and for the design of smart probes that are thermo- and pH-responsive.

Let E be a Denjoy Carleman class of ultradifferentiable functions of Beurling type on the real line that strictly contains another class F of Roumieu type. We show that the set S of functions in E that are nowhere in the class F is large in the topological sense (it is residual), in the measure theoretic sense (it is prevalent), and that SU{0} contains an infinite dimensional linear subspace (it is lineable). Consequences for the Gevrey classes are given. Similar results are also obtained for classes of ultradifferentiable functions defined imposing conditions on the Fourier Laplace transform of the function. [less ▲]

Denjoy-Carleman classes are spaces of smooth functions which satisfy growth conditions on their derivatives. We distinguish the class of ultradi fferentiable functions of Roumieu type and the class of ultradi fferentiable functions of Beurling typ. Endowed with its natural topology, the Beurling class is a Fr échet space. In the poster, we give a condition to have the strict inclusion of a Roumieu class into aBeurling class. We obtain then generic results about the set of functions of a Beurling class which are nowhere in a Roumieu class. Those generic results are obtained from three di fferent points of view: using the Baire category theorem, the notion of prevalence and the notion of lineability. We also study the particular case of Gevrey classes. [less ▲]

Two major challenges for enabling the vision of cloud computing regard (a) the generic and multi-purpose access to (virtualised) resources, and (b) the flexible, dynamic, and on-demand composition of services from virtual resources; from the service level, all the way ``down'' to the lamda level. Both aspects require a respective flexibility and expressibility from the interfaces in-place, which is missing from the current static socket (and other) interfaces below the application level. In this position paper, we propose, explain and exemplify an alternative generic and universal resource interface (GRI) that borrows from object oriented design to enable properties such as polymorphic access, generic service composition, introspection and dynamic reconfigurability, of in-network resources, opening in this way the path for flexible creation of service clouds.

The enantioseparation of ten basic drugs was evaluated in NACE systems using heptakis(2-O-methyl-3-O-acetyl-6-O-sulfo)-β-CD (HMAS-β-CD). For this purpose, a D-optimal design with 21 experimental points was applied. Four antifungal agents (econazole, isoconazole, miconazole, sulconazole), three local anesthetics (bupivacaine, mepivacaine and prilocaine), two sympathomimetics (salbutamol and terbutaline) and one β-blocker (carvedilol) were selected as basic model analytes. The influence on the enantiomeric resolution of anionic CD and BGE anion concentrations as well as the BGE anion nature was investigated. For all studied analytes, the enantiomeric resolution was shown to be significantly influenced by the CD concentration. Based on the observed results, a generic NACE system was recommended, namely 20 mM HMAS-β-CD and 10 mM ammonium camphorSO3- in methanol acidified with 0.75 M formic acid. Moreover, this NACE system was compared to previous conditions with heptakis(2,3-di-O-methyl-6-O-sulfo)-β-CD (HDMS-β-CD) or heptakis(2,3-di-O-acetyl-6-O-sulfo)-β-CD (HDAS-β-CD). Finally, two generic systems using either HDAS-β-CD or HMAS-β-CD were proposed and evaluated for the enantioseparation of ketamine and norketamine after incubation of ketamine in phenobarbital-induced male rat liver microsomes systems.

Parallèlement aux multiples commentaires cinéphiliques que le générique suscite depuis plusieurs années, les travaux récents qui lui sont consacrés l’envisagent comme un objet d’étude esthétique, narratologique ou sémiologique à part entière. Selon ces études, le générique est un objet fragmentaire (placé majoritairement à partir des années 1960 « sur » les images du début ou de la fin d’un film) voire autonome (on connaît les auteurs spécialisés en réalisation de génériques), marginal aussi (rarement au centre de l’œuvre ; le « générique-préface » de de Mourgues), frontalier encore (dans et hors du film, ou plutôt : à son orée), qui fait office d’ouverture ou de clôture hybride du film. Appartenant à la fois à l’univers de la fiction et à « un autre espace-temps, réel, celui de la production » (Moinereau), le générique de début plus particulièrement sert à « enclencher la diégèse » (de Mourgues) mais aussi à lui résister. « [S]orte de zone franche entre le monde de la réalité et celui de la fiction » (Metz), il est une passerelle, une aide au passage, au basculement dans la fiction. En tant que point pivot bâtard, le générique de début – et non pas « du début », appellation qui sous-entendrait l’appartenance exclusive à un seul lieu –, joue en effet sur deux registres. D’une part il affiche la ou les paternités bien réelles de l’œuvre (jusqu’au début des années 1910 il ne satisfait bien souvent qu’à cette seule obligation légale) et leur rend hommage (graphismes et durées différenciées), ou, dans ses versions les plus sophistiquées, offre au cinéphile (auto-)références et private jokes qui établissent entre le spectateur et l’auteur réel une complicité néanmoins non fatale pour le récit de fiction. D’autre part il aide le spectateur à s’abandonner à l’illusion de la fiction qui doit « mentir sur ses conditions de production » (Comolli) et dont le générique est pourtant le premier symptôme. En somme, le générique de début n’est donc pas seulement hybride par son lieu, mais aussi en raison de sa fonction quasi paradoxale : il établit avec le spectateur un lien a priori adiégétique dont la fonction première est précisément de faciliter son entrée dans la diégèse. Compte tenu de l’intérêt particulier que ces études accordent à la nature hybride du générique, il n’est pas étonnant que les travaux auxquels nous nous référons ici concernent exclusivement des films de fiction. Car, à l’inverse, dans le cas du cinéma documentaire, l’ambivalence inhérente à ce « commutateur de diégèse » (Gardies) est, en principe, inexistante étant donné que le générique d’un film non-fictionnel renvoie le spectateur à un univers « uniquement » réel, commun à l’ensemble du discours filmique. Dans cette perspective, il ne sert donc a priori qu’à inaugurer un contrat spectatoriel ou à poser les fondements d’une convention de lecture qui s’épanouira et développera sa pleine puissance dans le film (installation du principal médiateur, authentification de l’énonciateur, etc.). En documentaire, pas de conflit donc entre un espace-temps « adiégétique » et le film, entre la marge et le texte, car tous deux convoquent des éléments appartenant in fine au même registre, celui du réel. C’est en substance ce que suggère l’approche sémio-pragmatique du documentaire en envisageant le générique de début comme le lieu dans lequel un « je-origine réel » (Odin), par le biais de médiations institutionnelles ou non, prend ses quartiers dans le texte, ouvrant ainsi la voie à une « lecture documentarisante » incontestée dans la suite du film. Les paradigmes trop rapidement évoqués ici révèlent leurs limites dès lors qu’on les confronte à quelques sous-genres particulièrement pratiqués et populaires aujourd’hui tels que le faux documentaire, le docufiction, le mockumentary et le programme de télé-réalité. Se jouant précisément d’un contrat de lecture unilatéral et libre de tout malentendu, ces sous-genres documentaires brouillent la binarité posée par l’approche sémio-pragmatique (« documentarisant » vs « fictionalisant »). Notre analyse de quelques génériques, prégénériques et séquences d’annonce de faux documentaires, de mockumentaries et d’émissions de télé-réalité nous amène à redéfinir le contrat de lecture et les conventions qui y sont liées, propres au cinéma et à la télévision de non-fiction. Ces génériques ne contribuent pas à l’identification par le spectateur d’un énonciateur considéré comme réel (par jeu ou par conviction), mais établissent un nouvel accord tacite et flou entre un auteur reconnu comme fictif (ou ses avatars particulièrement nombreux dans le cas du mockumentary et de la télé-réalité) et le spectateur. Ce nouvel accord vise en réalité à produire l’adhésion forcée d’un spectateur qui pourtant sait qu’il n’est pas dupe, ou croit le savoir. Dans ce sens, le générique apparaît alors comme un lieu crucial pour toute analyse critique du discours non fictionnel : un lieu qui conteste l’authenticité de l’énonciateur et qui nie le crédit accordé au médiateur documentaire, pour offrir au public l’illusion de sa lucidité et le pousser ensuite vers une adhésion sans réserve à un jeu de réel. En somme, une étape indispensable à la constitution d’une crédulité paradoxale du spectateur. [less ▲]
