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 ▲]

The European Space Agency's Darwin and NASA's Terrestrial Planet Finder (TPF) are among the most challenging space science missions ever considered. Their principal objective is to detect Earth-like planets around nearby stars and to characterize their atmospheres. Darwin and TPF-I are currently conceived as nulling interferometers with free-flying telescopes. Within the frame of the Darwin program, the ESA and the European Southern Observatory (ESO), supported by European industries and scientific institutes, have performed two parallel Phase A studies of a ground-based nulling interferometry experiment (GENIE) at the site of ESO's Very Large Telescope Interferometer (VLTI) in Paranal, Chile. GENIE will demonstrate several key technologies required for the Darwin mission. Its science objectives include the detection and characterization of dust disks and low-mass companions around nearby stars. These studies have established detailed instrumental designs, in which GENIE will operate in the L' band around 3.8 microns as a single Bracewell nulling or constructive interferometer, using either two Auxiliary or two Unit Telescopes. The studies were supported by detailed numerical simulations which indicated the possibility of detection and low-resolution spectroscopy in nulling mode of extra-solar giant planets (EGPs) with atmospheric temperatures down to 700 K, provided that a proper calibration of instrumental effects is applied. Detection of circumstellar exo-zodiacal (EZ) dust clouds is possible down to 0.5 mJy, with interesting prospects for the characterization of planet-forming disks. [less ▲]

The aim of this paper is to validate numerical simula- tions of electromechanical coupling in micro-structures using some experimental results. The micro-structures studied here consist in a micro-bridge and two cantilever micro-beams. Multi-physics models of micro-electro- mechanical systems (MEMS) based on the ¯nite ele- ment method (FEM) are used to model the strongly coupled electro-mechanical interactions and to perform static analyses taking into account large displacements. In all the cases treated here the numerical results are in very good agreement with the experimental results. [less ▲]

In order to compute the reachability set of infinite-state models, one needs a technique for exploring infinite sequences of transitions in finite time, as well as a symbolic representation for the finite and infinite sets of configurations that are to be handled. The representation problem can be solved by automata-based methods, which consist in representing a set by a finite-state machine recognizing its elements, suitably encoded as words over a finite alphabet. Automata-based set representations have many advantages: They are expressive, easy to manipulate, and admit a canonical form. In this survey, we describe two automata-based structures that have been developed for representing sets of numbers (or, more generally, of vectors): The Number Decision Diagram (NDD) for integer values, and the Real Vector Automaton (RVA) for real numbers. We discuss the expressiveness of these structures, present some construction algorithms, and give a brief introduction to some related acceleration techniques. [less ▲]

The Hilbert-Huang transform (HHT) has been shown to be effective for characterizing a wide range of nonstationary signals in terms of elemental components through what has been called the empirical mode decomposition. The HHT has been utilized extensively despite the absence of a serious analytical foundation, as it provides a concise basis for the analysis of strongly nonlinear systems. In this paper, we attempt to provide the missing link, showing the relationship between the EMD and the slow-flow equations of the system. The slow-flow model is established by performing a partition between slow and fast dynamics using the complexification-averaging technique, and a dynamical system described by slowly-varying amplitudes and phases is obtained. These variables can also be extracted directly from the experimental measurements using the Hilbert transform coupled with the EMD. The comparison between the experimental and analytical results forms the basis of a nonlinear system identification method, termed the slow-flow model identification method, which is demonstrated using numerical examples.

When resorting to numerical algorithms, we show that nonlinear normal mode (NNM) computation is possible with limited implementation effort, which paves the way to a practical method for determining the NNMs of nonlinear mechanical systems. The proposed method relies on two main techniques, namely a shooting procedure and a method for the continuation of NNM motions. In addition, sensitivity analysis is used to reduce the computational burden of the algorithm. A simplified discrete model of a nonlinear bladed disk is considered to demonstrate the developments.

After an initial positive response to anti-androgen treatment, prostate cancer (PCa) cells usually become hormone-refractory in spite of their persistent expression of the androgen receptor (AR). Overexpression of tyrosine kinase receptors in androgen-deprived PCa cells, such as those of the EGF receptor (EGFR) family, may be responsible for AR activation and growth of androgen-deprived tumours. Our goal is to understand the control of the expression of the EGFR family members by androgens in PCa. Hormone response was compared in hormone-sensitive LNCaP and hormone-insensitive DU145 PCa cell lines. These cells do not express ErbB4. EGFR, erbB2 and erbB3 protein half-life is much longer in DU145 than in LNCaP cells grown in complete medium. Dihydrotestosterone (DHT) modulates EGFR and erbB2 transcript and protein levels only in LNCaP cells. ErbB3 is not an androgen-responsive gene. EGFR mRNA and protein levels are increased while erbB2 mRNA and protein levels are decreased after DHT treatment of cells cultured in steroid-deprived medium. ErbB2 mRNA and protein levels are increased in LNCaP cells following DHT withdrawal. In order to understand the mechanisms by which androgens control the expression of EGFR and ERBB2 genes, half lifes of the corresponding mRNAs and proteins were compared in cells grown in presence or absence of DHT. The effect of DHT on EGFR gene expression is complex. Indeed, DHT stabilizes the protein. Moreover, a superinduction of EGFR mRNA was observed in cells treated with cycloheximide (CHX) before addition of the hormone, suggesting an effect on transcript stability. In contrast, erbB2 mRNA and protein stability was not affected by DHT. CHX treatment for 2h before addition of DHT suppresses the androgen-induced down-regulation of erbB2 mRNA levels. In summary, androgen-mediated regulation of EGFR and ERBB2 genes expression is complex. DHT influences EGFR gene transcription, mRNA and protein stability. DHT does not affect erbB2 mRNA and protein stability but acts indirectly on transcription. Current experiments are undertaken to verify these observations by Chromatin-IP experiments on both genes promoters. [less ▲]

Results of FEM simulations predicting the mechanical behavior at room temperature of test specimens of ultrafine-grained aluminum produced by ECAE are presented. The constitutive law is either based on a Hill model or on the Minty micro-macro model and coupled with an isotropic hardening law and/or kinematic hardening law. The yield locus shape, its size and its position during tension, compression and torsion tests have been studied. Initial texture measurements allow the identification of a constitutive law based on a set of representative crystals and crystal plasticity approach using a Full- Constraint Taylor model. Finite element simulations using the previous constitutive laws are compared with experimental investigations. The results show that applying an initial back stress identified by tensile and compression tests to the yield locus predicts the initial flow stress in torsion test. The Minty micro-macro model coupled with a Voce type hardening model gives a good agreement with experimental results for the prediction of the shape at different stages of deformation of a compressed test specimen. The simulation of tensile tests underline the need of inverse modeling as, due to the test specimen shape, the test is far from being homogeneous. The link between test specimen length and the necking appearance is studied. [less ▲]

This paper presents results ofanumerical study onreinforced concrete and fully encased composite columns designed according to the “Inerd” concept aiming at obviating the soft storey mechanism in frames subjected to earthquake. The model uses fibre beam elements with mono-axial non linear material laws for concrete, steel and reinforcing steel. The crushing of concrete in compression and the cracking in tension are taken into account. The steel behaviour is elastic-plastic with strain hardening. After calibration of the model against experimental results, a parametric study is performed. The main objective is to generate the cyclic moment-rotation curves of the columns under different level of axial forces and with different proper-ties of concrete and then to deduce ductility and rotation capacity of the composite sections from these curves.

The total concentrations of trace elements in soils results from natural and anthropic factors. Knowledge of natural distribution (e.g. bio-geochemical background) helps assessing the impacts of human activities in terms of contaminations. But the processes generated by the modifications of the soil environment may also affect the form of a trace element, that is its distribution through various pools. We investigated the chemical speciation of some metallic trace elements (Cu, Zn, Cr, Ni, Pb, Co, Cd) in soils from various land-use environment: “natural” soils under forest, “typical” cultivated soils, kitchen-garden soils, soils developped on geogenic anomalies and on contaminated areas. The analysis protocol aims at identifying different pools from their reaction to various extraction phases, ordered by increasing intensity in a single sequence. The different fractions are so-called soluble, linked to carbonates, to organic matter, to manganese oxides, to weakly cristallized Fe-Al oxides, to well-cristallized oxides, and residual. The “available” and total fractions have also been measured. The results stress the fact that the comparisons are difficult from one situation to another because each one represents a particular case of human activity without a common logic. The relationships with the classical pedological parameters are therefore difficult to generalize. However some relationships between elements have been found inside the various types of land use, which could be usefull in the risk assesment of transfers from soils to plants. [less ▲]

Runoff rates turn to be relatively stable during the exposure time. The influence of alloying elements on the copper runoff rate has been studied and it was demonstrated that addition of zinc permit to decrease the amount of copper that releases from the corroded surface by rainfall. Concerning the tin content, no significant influence has been observed on the copper runoff [less ▲]

Introduction : Le seuil de sensibilité à la douleur (SSD) peut être apprécié à partir de la pression minimale induisant une perception nociceptive. Ce seuil s’objective aisément en pratique clinique par une mesure dolorimétrique. Le but de ce travail consiste à comparer, à partir d’une mesure dolorimétrique, le SSD de sujets contrôles et fibromyalgiques et, d’autre part, d’établir des valeurs normatives. Patients et méthodes : Cent sujets contrôles (50 féminins et 50 masculins) et 20 patientes fibromyalgiques sont inclus dans l’étude. Le SSD des 18 points sensibles définis par le Collège Américain de Rhumatologie dans le cadre des critères de classification de la fibromyalgie est mesuré à partir d’un dolorimètre électronique. La pression transmise est augmentée graduellement au rythme de 1 kg/cm² chaque seconde et ce, jusqu’à l’apparition d’une véritable douleur, et non plus d’une simple sensibilité. Le SSD (en kg/cm²) des 9 points spécifiques bilatéraux est déterminé et un score myalgique s’établit par l’addition de ceux-ci. Un test-retest réalisé à 3 jours d’intervalle apprécie la reproductibilité intra-examinateur des SSD. Résultats : Les coefficients de variation correspondent respectivement à 17 % et 13 % chez les sujets contrôles féminins et masculins, et 24 % chez les fibromyalgiques. La reproductibilité apparaît la plus favorable pour les points « fessier » et « genou ». Les SSD s’avèrent significativement inférieurs chez les sujets contrôles féminins en comparaison des volontaires masculins (p < 0,01) et aucun effet de latéralité n’est constaté. Les SSD mesurés chez les fibromyalgiques demeurent systématiquement inférieurs (réduction de 60 %) à ceux de la population contrôle (p < 0,0001). Les SSD les plus faibles sont mesurés aux points « trapèze », « occiput », « cervical antérieur » et « 2ème côte » tant chez les sujets contrôles que fibromyalgiques. Le score myalgique atteint 20 + 7,4 kg/cm² et 49,9 kg/cm² respectivement chez les patients fibromyalgiques et chez les sujets contrôles féminins. Discussion : Une mesure dolorimétrique permet d’objectiver le SSD avec une reproductibilité satisfaisante. Ce travail démontre des valeurs de SSD particulièrement faibles chez les fibromyalgiques. De façon originale, nous objectivons, chez les sujets contrôles, particulièrement de sexe féminin, des SSD souvent inférieurs au seuil décrit par l’ACR (4 kg/cm²). Conclusion : L’établissement d’un score myalgique permet d’apprécier, à partir d’une mesure dolorimétrique, la sensibilité nociceptive et offre la possibilité d’un suivi longitudinal du patient en terme de douleur.

Data were based on results for type traits (77,965 records) and for direct longevity (74,289 records) from the INTERBULL routine run of November 2005. Most of type traits presented a high relationship with direct longevity (from 0.06 up to 0.29). The strongest positive correlation with longevity was for udder depth (0.29) and the strongest negative correlation was for chest depth (-0.21).

In the family Pomacentridae, six genera were reported as sound producers: Amphiprion, Dascyllus, Stegastes, Chromis, Abudefduf and Plectroglyphidodon. The anemonefishes (Amphiprioninae) live in social group in association with sea anemones, which protect them from predators. Their sound emissions seem involved in courtship and territorial defense, contributing to both survival and reproductive success. However, the mechanism of sound production is unresolved. It has been hypothesized that it involves swimbladder or the action of the pharyngeal jaws amplified by swimbladder. The aim of this study was to understand the sonic mechanism involved in the agonistic sounds in Amphiprion clarkii. The approach consists in high-speed cineradiography and functional morphology. During agonistic sounds (pops), fishes perform different movements such as skull elevation, pectoral girdle retraction, hyoid lowering and mouth closing. Pops are produced when the hyoid is completely lowered and the mouth closed. The simultaneous realization of these movements was never observed in teleost. In Amphiprion sp., it is possible due to an additional ligament inserted on the hyoid bar and on the inner lower jaw. The hyoid lowering combined to the closing (and thus the elevation) of the mandible could generate a tension of the ligament, provoking its vibration [less ▲]

The study of adhesion of repair materials on concrete structures implies a good knowledge of the influence of concrete surface treatment. The effects of surface preparation technique is rarely clearly described and parameterised: it is consequently difficult to point out the real influence of roughness on adhesion results. A first step was made by using mechanical profilometry to differentiate concrete surfaces prepared by shot blasting, sand blasting and hand or mechanical milling. This technique is very accurate for investigations in laboratory, on a limited surface area. If Quality Control is requested or if it is impossible to core samples from the site, other procedures should be followed. That the reason why opto-morphometry analysis has been developed, in order to analyse larger surfaces. The comparison of the two techniques shows clearly the advan-tages of each one and the precision that can be achieved. [less ▲]

We extend tree-based methods to the prediction of structured outputs using a kernelization of the algorithm that allows one to grow trees as soon as a kernel can be defined on the output space. The resulting algorithm, called output kernel trees (OK3), generalizes classification and regression trees as well as tree-based ensemble methods in a principled way. It inherits several features of these methods such as interpretability, robustness to irrelevant variables, and input scalability. When only the Gram matrix over the outputs of the learning sample is given, it learns the output kernel as a function of inputs. We show that the proposed algorithm works well on an image reconstruction task and on a biological network inference problem. [less ▲]

Cet article porte sur un corpus de photographies écrites et peintes et concerne les relations (contractuelles et contrastives) entre texte photographique, écriture manuelle et gestualité picturale. L’écriture dans l’image est étudiée comme : 1) stratégie d’authentification de l’objet-photo (autographie de l’objet photographique unique), 2) comme notation, 3) comme gestualité, 4) comme effet-texture de l’image. 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 main objective of the present paper is a description of two effective numerical 2D models to be used as strategic tools in the process of flood risks assessment and mitigation. The first one is a model for hydrodynamics simplified according to the diffusive assumption while the second one is a complete model based on the shallow water equations. Each of them is solved with an efficient numerical technique (including implicit time integration schemes and GMRES linear solvers) maximizing the convergence rate towards a steady state. A practical case study, for which a high resolution Digital Elevation Model exists, will be presented. The study shows the consequences on structures of a new construction in the floodplain in terms of inundation and erosion. [less ▲]

Les débats médiatiques sur la mondialisation s’articulent autour de deux thèses apparemment antagonistes. Pour les partisans du libéralisme économique et les représentants des milieux d’affaires, il s’agit de condamner l’interventionnisme et le dirigisme politique dans le libre-jeu de l’économie de marché. Les chefs de file syndicaux et dirigeants réformistes de l’« altermondialisme », entendent, quant à eux, défendre, bec et ongles, l’idée d’un personnel politique victime de la bourse et des pressions de divers lobbies industriels et financiers. Dans les deux cas pourtant, on procède à une dissociation artificielle et trompeuse de l’économique et du politique. Cette représentation dominante de la mondialisation est à l’origine d’une censure, celle qui, derrière le paravent de l’Etat « victime » ou « bourreau » des marchés, refuse la parole aux critiques dénonçant les liens organiques entre pouvoirs économique, politique et médiatique.

Learning regulatory networks from time-series of gene expres- sion is a challenging task. We propose to use synthetic data to analyze the ability of a state-space model to retrieve the network structure while varying a number of relevant problem parameters. ROC curves together with new tools such as spectral clustering of local solutions found by EM are used to analyze these results and provide relevant insights. [less ▲]
