We propose an innovative concept for a DARWIN pathfinder experiment. It involves an integrated nulling interferometer of relatively modest dimensions (two 1 m class collectors on a 40 m truss), which would take advantage of a privileged location (at Dome C on the Antarctic plateau) to perform better than a nulling instrument on a large interferometer (such as GENIE at the VLTI).

Using the FLUOR beam-combiner at the CHARA Array, we have obtained highprecision visibility measurements of Vega, a prototypic debris-disk star. The combination of long and short baselines has allowed us to separately resolve the stellar photosphere and the close environment of the star (< 8 AU). Our observations show a significant deficit in square visibility at short baselines with respect to the expected visibility of a simple uniform disk stellar model, suggesting the presence of an extended source around Vega. We propose that the excess emission is most likely due to the presence of hot circumstellar dust in the inner part of Vega's debris disk, with a flux ratio of 1.29 ± 0.19% between the integrated dust emission and the stellar photosphere. Using this information together with archival photometric measurements in the nearand mid-infrared, we derive the expected physical properties of the circumstellar dust by modelling its infrared Spectral Energy Distribution. The inferred properties suggest that the Vega system could be currently undergoing major dynamical perturbations. [less ▲]

We have obtained high-precision interferometric measurements of the A0 V standard star Vega with the Center for High Angular Resolution Astronomy (CHARA) Array and the Fiber Linked Unit for Optical Recombination (FLUOR) beam combiner in the K' band at projected baselines between 103 m and 273 m. The measured squared visibility amplitudes beyond the first lobe are significantly weaker than expected for a slowly rotating star and provide strong evidence for the model of Vega as a rapidly rotating star viewed very nearly pole on. We have constructed a Roche-von Zeipel gravity-darkened model atmosphere which is in generally good agreement with both our interferometric data and archival spectrophotometry. Our model indicates Vega is rotating at Ë 92% of its angular break-up rate with an equatorial velocity of Ë 275 km s[SUP]-1[/SUP]. We find a polar effective temperature of Ë 10150 K and a pole-to-equator effective temperature difference of Ë 2500 K, much larger than the Ë 300 K derived by Gulliver, Hill, and Adelman. Our model suggests that Vega's cool equatorial atmosphere may have significant convective flux and predicts a significantly cooler spectral energy distribution for Vega as seen by its surrounding debris disk. This work was performed in part under contract with the Jet Propulsion Laboratory (JPL) funded by NASA through the Michelson Fellowship Program. JPL is managed for NASA by the California Institute of Technology. The CHARA Array is operated by the Center for High Angular Resolution Astronomy with support from Georgia State University and the National Science Foundation, the Keck Foundation and the Packard Foundation.

A reduction of the carbonate-carbon to organic-carbon export rain ratio during glacial times is commonly advanced to explain an important part of the observed glacial-interglacial atmospheric CO2 variation. This hypothesis was tested and side-effects on the evolution of carbonate preservation/dissolution in the surface sediment explored with a multi-box model (MBM) of the ocean carbon cycle, fully coupled to a new transient advection-diffusion-reaction model (called MEDUSA) representing early diagenesis processes of carbonate minerals in the surface sediment. MEDUSA explicitly considers the role of organic matter remineralisation in the sediment column to enhance calcite (and aragonite) dissolution. It is fully bi-directional and takes chemical erosion into account in times when carbonate dissolution makes the sediment mixed-layer collapse faster than the sediment supply to the surface is able to counterbalance. Coupled model experiments were run for 240,000 years, forced by variable sea-level, temperature and salinity histories, and variable continental weathering inputs. Various scenarios for the evolution of the rain ratio over glacial to interglacial periods were adopted. A peak reduction of the rain ratio by 40% at the Last Glacial Maximum (LGM) was found to produce a net atmospheric pCO2 reduction of about 30ppm, on top of a 60ppm reduction produced by changing continental shelf carbonate accumulation and changing continental weathering inputs. The overall 90ppm oscillation compares well with the observed data. However, the effect on the model sedimentary record is clearly at odds with actual sediment records. The changes related to continental shelf processes and variable weathering flux depress the calcite saturation horizon by about 1km at the LGM; if rain ratio variations are also considered, that depression increases by another km. An assessment of the respective contributions from various model parameters will be presented. [less ▲]

In order to face the strong competitions of globalization and internationalization, modern enterprises require high quality logistics services for their economic interests, production requisites and market changes to enhance their competitive positions. In accordance with the sustainable socio-economic developments, the enterprises should comply with the social rules and regulations that aim at reducing the society costs such as congestion, pollution, and environmental protection. Intermodal transportation is an attractive solution for modern enterprises by offering economic, environmental friendly and door-to-door transport means that can easily be integrated into modern logistic chains. Making full use of the intermodal transport has become a strategic measure for many enterprises in their logistical organization, with many successful stories. However, the tendency of implementing intermodal transport has not been recognized well by certain enterprises. Some barriers and bottlenecks block the proper integration and organization of intermodal logistical chains, which are indispensable for the logistics of enterprises. In order to optimize the structure of transport system and to help enterprises implement modern and innovative technologies, a study was carried out in Belgium, with the representative characteristics of Western Europe, to identify the potential of utilizing intermodal transport and to search for the bottlenecks that break the logistical chains. This study supplies the decision makers and the enterprises useful suggestions to improve the intermodal transport services and the intermodal traffic. This paper will introduce main concepts and methods of this important study. [less ▲]

Comprendre la façon dont le cerveau travaille et en particulier le mode de communication de ses cellules est un rêve que beaucoup de chercheurs caressent. A l’heure actuelle, une des rares certitudes à son sujet est qu’un de ses modes de transmission d’informations utilise des « messagers » chimiques appelés neurotransmetteurs. Parmi ceux-ci, la sérotonine (5-HT) revêt une importance particulière. En effet, la 5-HT est impliquée dans de nombreuses fonctions (apprentissage, locomotion, sommeil,…) et pathologies (dépressions, démences, schizophrénies,…). Dès lors, l'étude in vivo chez l'homme des neurones sérotoninergiques ainsi que la quantification de la vitesse de biosynthèse de la 5-HT sont des domaines d'études fondamentaux pour lesquels la tomographie à émission de positons (TEP) constitue un outil de choix. Pour mener à bien ces différentes expérimentations, deux stratégies sont envisageables : - L’emploi d'un traceur capable de suivre la chaîne métabolique du tryptophane conduisant à la 5-HT tout en évitant les autres voies métaboliques. - L’utilisation d'un inhibiteur de la TrpOH (enzyme limitant du processus). Dans le cadre de cette présentation, nous nous intéresserons plus particulièrement à la deuxième stratégie. [less ▲]

Grid computing can be defined as coordinated resource sharing and problem solving in dynamic, multi-institutional collaborations. As more Grids are deployed worldwide, the number of multi-institutional collaborations is rapidly growing. However, for Grid computing to realize its full potential, it is expected that Grid participants are able to use one another resources. Resource negotiation (i.e. exchange or trading of resources between Grids) enables Grid participants to face an unstable request environment. The aim of this position paper is to present a survey of the current state and challenges of resource negotiation research, with a Machine Learning perspective. We support the view that negotiation and learning are intrinsically linked. In particular, we show the expected benefits of integrating Machine Learning techniques with resource negotiation.

Considered as the core of the Sco OB1 association, the young open cluster NGC 6231 harbours a rich O-type star population. In 2001, the XMM-Newton satellite targeted the cluster for a nominal duration of about 180 ks. Thanks to the detector sensitivity, the EPIC cameras provided an unprecedented X-ray view of NGC 6231, revealing about 600 point-like sources. In this contribution, we review the main results that have been obtained thanks to this unprecedented data set. Concerning the O-type stars, we present the latest developments related to the so-called 'canonical' Lx-Lbol relation. The dispersion around this relation might actually be much smaller than previously thought. In our data set, the sole mechanism that yields a significant deviation from this scheme is wind interaction. It is also the sole mechanism that induces a significant variation of the early-type star X-ray flux. In a second part of this contribution, we probe the properties of the optically faint X-ray sources. Most of them are believed to be low mass pre-main sequence stars. Their analysis provides direct insight into the star formation history of the cluster. [less ▲]

La bipolarité en pédopsychiatrie : proposition d'une nouvelle sémiologie. Le diagnostic de bipolarité reste peu connu des pédopsychiatres. Il faut en moyenne 10 ans et 3 à 5 médecins avant qu'un diagnostic correct ne soit posé. Notre expérience, se rapportant à plus d'une centaine d'enfants de 20 mois à 8 ans, met en évidence une sémiologie nuancée qui permet un diagnostic rapide et précoce de la bipolarité. Nous relevons un "tempérament maniaque bipolaire simple" avec sept axes sémiologiques : 1. la clinique du sommeil, 2. une forme "super-énergétique", 3. un "mal-être en situation d'être seul", 4. des couleurs affectives expressives, 5. les désinhibitions, 6. la prépondérance de l'attention divergente sur l'attention convergente, 7. la tendance à l'hyperactivité. Nous évoquons pour ces sept axes l'expression clinique par tranche d'âge jusqu'à la vie adulte. La mise en évidence d'une clinique du "mal-être en situation d'être seul" est l'élément le plus original de notre recherche ; ce mal-être est à distinguer de l'angoisse de séparation, même s'il peut y avoir un continuum ; il n'est pas pathognomonique de la bipolarité mais semble en faire systématiquement partie ; nous formulons l'hypothèse qu'il serait lié à un manque d'efficience "d'une jauge interne d'évaluation du temps". Nous donnons le diagnostic différentiel entre le "tempérament maniaque bipolaire simple" et l'ADHD. Ensuite, nous proposons une caractérisation en 4 formes sémiologiques des états bipolaires dans l'enfance. Nous complétons cette sémiologie de base par différentes comorbidités possibles qui vont apporter d'autres accentuations cliniques. Nous mentionnons le diagnostic différentiel avec les troubles schizo-affectifs. Selon le temps imparti nous pouvons également évoquer : des métaphores explicatives et thérapeutiques que nous donnons au lieu de parler de diagnostic ; des réflexions neurophysiologiques jointes à cette sémiologie ; les médications spécifiques et leur efficacité dans la petite enfance ; le pronostic qui peut radicalement changer avec une prise en charge précoce.

We introduce a general technique for creating an extended formulation of a mixed-integer program. We classify the integer variables into blocks, each of which generates a finite set of vector values. The extended formulation is constructed by creating a new binary variable for each generated value. Initial experiments show that the extended formulation can have a more compact complete description than the original formulation. We prove that, using this reformulation technique, the facet description decomposes into one “linking polyhedron” per block and the “aggregated polyhedron”. Each of these polyhedra can be analyzed separately. For the case of identical coefficients in a block, we provide a complete description of the linking polyhedron and a polynomial-time separation algorithm. Applied to the knapsack with a fixed number of distinct coefficients, this theorem provides a complete description in an extended space with a polynomial number of variables. On the basis of this theory, we propose a new branching scheme that analyzes the problem structure. It is designed to be applied in those subproblems of hard integer programs where LP-based techniques do not provide good branching decisions. Preliminary computational experiments show that it is successful for some benchmark problems of multi-knapsack type. [less ▲]

En complément de « la clinique de la neurophysiologie » exposée par le Dr Scholl, différentes situations rencontrées en consultations seront présentées pour donner un tableau clinique de quelques enfants à agés de 3 à 7 ans. Ensuite, à partir de la Classification diagnostique « Zero to three », la symptomatologie décrite sera revue à la recherche d'éventuels troubles de la régulation. Notre objectif est d'y montrer l'existence de signes cliniques propres à des dysfonctionnements neurophysiologiques. Cette démarche jette un nouveau regard sur les situations cliniques ; elle permet aussi - selon notre expérience - une meilleure prise en compte de toutes les réalités de l'enfant et de ses parents dans une perspective thérapeutique.

Troubles de la régulation du "0 to 3" : la clinique de la neurophysiologie. Dans la Classification "0 to 3" (DC:0-3R), pour diagnostiquer un trouble de la régulation, outre les attitudes de l'enfant correspondant à un des tableaux cliniques, il faut observer au moins une difficulté sensorielle, sensori-motrice ou du traitement de l'information. Ce dernier point peut déconcerter le clinicien qui cherche à se former à cette nomenclature car il est peu habitué, dans la pratique de psychothérapie, à rechercher ces difficultés et encore moins à les lire en termes neurophysiologiques. "Les troubles de la régulation" sont caractérisés par les difficultés du bébé ou du jeune enfant à réguler leurs comportements et leurs processus physiologiques sensoriels, d'attention, moteurs ou émotionnels et à maintenir un état de calme, de vigilance ou un état émotionnel positif. Les processus physiologiques impliqués se rapportent à des difficultés de traitement de l'information sensorielle, sensori-motrice ou de son organisation, telles que des difficultés à réguler, à intégrer et à répondre à divers types de sensations (y compris auditives et visuelles) et à divers types d'affects. On présume que les patterns sensoriels, moteurs et intégratifs sont d'origine "constitutionnelle", avec une influence des processus de maturation neurologique et aussi des différents modes de soins précoces. L'objectif de cet exposé est de donner un sens clinique de la composante neurophysiologique de ces difficultés et de développer une sémiologie de micro-signes repérables dans la clinique et l'anamnèse. Une attention particulière est donnée au traitement de l'information visuo-spatiale, auditivo-verbale, à la perception des affects, aux modalités de leurs expressions, au "niveau énergétique", à l'organisation de la sphère buccale, à l'hyper ou l'hyposensibilité de chacun des canaux sensoriels et à tout ce qui est en lien à un support neurophysiologique. Cette étude voudrait contribuer, à partir de la symptomatologie, à un meilleur discernement -- dans un continuum -- entre la part neurophysiologique et la part psychologique intervenant dans les difficultés de l'enfant. Cette clinique est à la convergence de l'intérêt tant des pédopsychiatres que des neuropédiatres confrontés à des enfants de 0 à 5 ans. [less ▲]

Supplied by the Ganga–Brahmaputra fluvial system, the Bengal Fan provides an integrated record of the Himalayan basin history through time. The active channel-levee system of the middle fan documents the last glacial/interglacial cycle. Organic geochemistry studies have shown that the organic matter contained in the Bengal Fan sediments is mainly of terrestrial origin. We analysed terrestrial n-alkanes (C27–C33) from Bengal Fan sediments and modern Ganga–Brahmaputra sediments. Comparison of compound specific hydrogen and carbon isotopic ratios in these samples allow us to follow the evolution of paleoenvironmental conditions since the Last Glacial Maximum. Carbon molecular isotopic data on the odd-HMW n-alkanes show a shift of 4&, corresponding to an evolution in the Himalayan system from a C4-dominated vegetation at LGM to a C3- dominated vegetation during the Holocene. It is now well known that C4 plants are more adapted than C3 plants to low atmospheric CO2 concentrations and to relatively hot and dry climate. In the same time, molecular D/H isotopic ratios measured on the same samples show an increase of the deuterium content of about 20& during the Holocene, which is consistent with lower temperature at the end of the LGM in the Himalaya. As low temperature should favored C3 plants, the predominance of a C4 vegetation have to be linked with dryer conditions at the end of the LGM. Afterwards, the increase of the C3/C4 ratio in the Himalayan system is related to a concomitant increase of humidity and pCO2 during the Holocene. [less ▲]

In the global framework of river management, sedimentation problems in dam reservoirs and adjacent structures are multiple and of major interest for designers as well as dam owners or managers. Before dam construction, these problems can be assessed by several techniques. In this paper, the experimental and numerical sedimentation studies realized at the Laboratory of Applied Hydrodynamics and Hydraulic Constructions (HACH) of the University of Liège on a large hydropower plant project in India are presented. Three main issues related to sedimentation problems are analyzed in details. [less ▲]

This paper describes the successful combination of both physical and numerical modelling techniques applied to the scale model study of a large hydroelectric complex in India. Thanks to accurate numerical simulations, the physical model layout and the time to studies have been drastically reduced. First, prior to the design of the scale model, a global numerical simulation of the dam reservoir has been carried out, on the basis of the entire set of available topographic data. The simulation results supply the flow conditions in the upstream reservoir, particularly in the vicinity of the dam and the spillway crest. Subsequently, a second numerical computation has been performed to simulate the flow in a scale model representing only a small part of the reservoir upstream of the dam. The suitable correspondence between flow conditions in both cases has been demonstrated. This two-steps approach has enabled a significant reduction in the size of the scale model, and hence, a lower cost as well as a shorter delay for building the model. Simultaneously, it has been possible to decrease the scale factor at constant cost. In conclusion, the present paper provides convincing evidence that the increase in computers performance and the efficiency of contemporary free-surface flow solvers lead to useful numerical information for the optimal design and exploitation of scale models.

L’écriture entendue comme stratégie d’authentification du texte photographique permet de réfléchir sur la problématique de l’original, de la reproductibilité et du statut hybride de la photographie écrite, à mi-chemin entre autographie et allographie (« texte autographique à objet multiple »).

The accuracy of a Finite Element Simulation for plastic deformation strongly depends on the chosen constitutive laws and the value of the material parameters within these laws. The identification of those mechanical parameters can be done based on homogeneous stress and strain fields such as those obtained in uniaxial tensile tests and simple shear tests performed in different plane material directions. Another way to identify plastic material parameters is by inverse modeling of an experiment exhibiting a heterogeneous stress and strain field. Experimental forces and strains are in this case compared to the simulated ones and it is tried to reduce the difference in a least-squares sense by optimizing the model parameters. The optimization technique used is this case is gradient based, which means that at every iteration a sensitivity calculation has to be performed in order to indicate the direction in which the parameters are to be identified. The basic principle of the inverse modeling procedure as it is used for parameter identification is the generation of a complex and heterogeneous deformation field that contains as much information as possible about the parameters to be identified. One way of obtaining such a non-homogeneous deformation is by altering the geometry of the specimen for a uniaxial test. Another possibility is to make the loading conditions more complex. In this paper both options are actually combined by using a biaxial tensile test on a perforated cruciform specimen. In the present paper, the work hardening of the material is assumed to be isotropic and it is described by a Swift law. The yield locus is modeled by the anisotropic Hill48 criterion. A comparison is made between the identification of the Hill48 parameters based on the one hand on the Lankford coefficients [1] and on the inverse modeling of a biaxial tensile test on the other hand [less ▲]
