Résumé : The fining upward trend commonly described on levees of turbidite systems can be either attributed to changes in the sediment supply (external forcing = allocyclic) or changes in the spillover processes related to the growth of the levee (internal forcing = autocyclic). However the real causes remain speculative and difficult to demonstrate. Knowledge of vertical change in flow velocity (or grain size) in turbidity currents, of the turbidity current's height, as well as the growth rate of a levee are theoretically sufficient to describe the evolution of the grain size of a leveed turbidite sequence deposited by spillover processes. A piston core (MD99-2344) retrieved on the right levee of the Petit-Rhone neofan, sampled an 8.50 m long turbidite sequence containing more than one hundred turbidite beds and showing a marked fining upward trend. With the help of two profiles describing respectively the vertical velocity [Stacey, M. and Bowen, A.J., 1988b. The vertical structure of turbidity currents and a necessary condition for self-maintenance, Journal of Geophysical Research, pp. 3543-3553.] and the vertical grain size [Migeon, S., 2000. Dunes geantes et levees sedimentaires en domaine marin profond: approche morphologique, sismique et sedimentologique. PhD Thesis, Universite Bordeaux 1, Talence, France, 288 pp.] of a turbidity current, and a simple graphical method, we test several hypotheses on the height of the turbidity current and on the grain size at the bottom of the turbidity current and we attempt to reproduce the vertical fining upward trend. Our results show that the fining upward trend of the turbidite facies can be explained by the aggradation of the turbidite levee and the gradual confinement of the turbidity currents in the channel. This is, therefore, an autocyclical phenomenon. However a high frequency variability of the grain size overprinted on the trend cannot be explained by internal forcing and is believed to be allocyclical, depending on changes to the sediment input. The vertical grain-size profile allows more realistic flow conditions to be determined and shows that the vertical velocity profile does not describe the ability of turbidity current to transport sediment. This simple graphical method allows a better understanding and quantification of the forcing on turbidite deposits and improves description of the characteristics of the turbidity currents from the grain size of the deposits.

Description : Le Contesté franco-brésilien est un différend soulevé entre les gouvernements français et brésilien, sur la question de la délimitation de la frontière entre la Guyane et le Brésil. Le protocole du 10 avril 1897, signé entre la France le Brésil détermine que la rivière Japoc ou Vincent Pinçon est l'Oyapoc et que la limite intérieure se forme à partir de la source principale de cette rivière jusqu'à la frontière hollandaise par la ligne de partage des eaux du bassin des Amazones qui, dans cette région est constituée dans sa presque totalité par la ligne de faîte des monts Tamuc-Humac.

Résumé : The seasonal variations of total dissolved copper were surveyed during one year (1983/1984) in the Aulne estuary (Western Brittany, France), an ecosystem with a high rate of water renewal. Copper in filtered water samples (after and without acidification) was determined after preconcentration on Chelex 100, and the eluates were analyzed by graphite furnace atomic absorption spectroscopy. The concentrations of free and complexed copper were then plotted versus chlorosity. Globally, the total dissolved copper concentrations tend to decrease with salinity. The role of physicochemical parameters such as pH and suspended matter (adsorption-desorption mechanisms) on dissolved copper content is shown to be significant. With a variable intensity, desorption (release) takes place in summer and in autumn, while adsorption is observed at very low chlorosity in winter. The dissolved copper concentrations in the Aulne estuary (0.26 to 2.52-mu-g.l-1, with the highest values in autumn) are similar to most estuarine copper values. The proportion of complexed species ranges from 4 to 69% (average of 27%).
Les variations saisonnières des concentrations en cuivre dissous dans l'estuaire de l'Aulne (Bretagne occidentale) ont été mesurées au cours d'un cycle annuel (1983/1984). Les concentrations en cuivre libre et celles en cuivre complexé ont été suivies séparément en fonction de la chlorosité, un paramètre conservatif. Les profils obtenus pour le cuivre total dissous montrent généralement une décroissance des teneurs en métal des eaux douces aux eaux marines, tout en restant supérieures à celles de la droite théorique de mélange. On montre le rôle fondamental de la variation du pH concomitante de celle de la matière en suspension (mécanisme d'adsorption-désorption) dans l'évolution des teneurs en cuivre dissous. Ce processus agit plus ou moins intensément dans le sens de la désorption (été, automne) ou de l'adsorption (hiver aux faibles chlorosités). Dans l'ensemble, les teneurs en cuivre total dissous (de 0,26 à 2,52 J.lg.l- 1 , les valeurs automnales étant les plus élevées) sont comparables à celles de nombreux autres écosystèmes estuariens, avec un taux de complexation compris entre 4 et 69% (moyenne de 27% ).

Résumé : International audience
EmailPrintRequest PermissionsThe emergence of new communication means such as online newspapers and exchange and sharing websites allow us to go further in the understanding of diffusion phenomena. Indeed, these public discussion areas are now firmly established in our societies and are known to be strong sensors of both human behaviors and collective feelings. In this paper we focus on diffusion phenomena that occur on Twitter and we propose a set of measures that aims to characterize globally and locally the processes. Our objective is to identify what are the conditions in which a person decides to forward the information. Our measures have been used to study two events occurred in January 2015: the presentation of Microsoft HoloLens, a new augmented reality headset, and the political election in Greece. The results obtained show a strong heterogeneity in the individual behaviours involved in the diffusion process. Our approach has been implemented into a graphical tool which is able to conduct real time analysis on any kind of topics occurring on Twitter.

Résumé : International audience
Motivation: Gene fusion is an important evolutionary process. It can yield valuable information to infer the interactions and functions of proteins. Fused genes have been identified as non-transitive patterns of similarity in triplets of genes. To be computationally tractable, this approach usually imposes an a priori distinction between a dataset in which fused genes are searched for, and a dataset that may have provided genetic material for fusion. This reduces the `genetic space' in which fusion can be discovered, as only a subset of triplets of genes is investigated. Moreover, this approach may have a high-false-positive rate, and it does not identify gene families descending from a common fusion event. Results: We represent similarities between sequences as a network. This leads to an efficient formulation of previous methods of fused gene identification, which we implemented in the Python program FusedTriplets. Furthermore, we propose a new characterization of families of fused genes, as clique minimal separators of the sequence similarity network. This well-studied graph topology provides a robust and fast method of detection, well suited for automatic analyses of big datasets. We implemented this method in the C++ program MosaicFinder, which additionally uses local alignments to discard false-positive candidates and indicates potential fusion points. The grouping into families will help distinguish sequencing or prediction errors from real biological fusions, and it will yield additional insight into the function and history of fused genes.

Résumé : International audience
The tree model and tree-based methods have played a major, fruitful role in evolutionary studies. However, with the increasing realization of the quantitative and qualitative importance of reticulate evolutionary processes, affecting all levels of biological organization, complementary network-based models and methods are now flourishing, inviting evolutionary biology to experience a network-thinking era. We show how relatively recent comers in this field of study, that is, sequence-similarity networks, genome networks, and gene families–genomes bipartite graphs, already allow for a significantly enhanced usage of molecular datasets in comparative studies. Analyses of these networks provide tools for tackling a multitude of complex phenomena, including the evolution of gene transfer, composite genes and genomes, evolutionary transitions, and holobionts.

Résumé : International audience
This study presents two algorithms that count birds with wireless sensors equipped with microphones. Audio inputs are parametrized to get some kind of fingerprints which are used to recognize the song of the birds in a classification process. Afterward, counting algorithms derive an estimate of the number of singing birds in the habitat. Unlike traditional approaches which leverage the audio waveform to get the location of the targets, we use a trilateration technique on graphs derived from the detection of the birds. These graphs exhibit nice properties which enable the finding of the estimate in polynomial time. Further, experiments are conducted and confirmm the efficiency of our counting algorithms even in the presence of noise.
