Résumé : The cephalochordate amphioxus (Branchiostoma sp.) is an important animal model for studying the evolution of chordate developmental mechanisms. Obtaining amphioxus embryos is a key step for these studies. It has been shown that an increase of 3-4 degrees C in water temperature triggers spawning of the European amphioxus (Branchiostoma lanceolatum) in captivity, however, very little is known about the natural spawning behavior of this species in the field. In this work, we have followed the spawning behavior of the European amphioxus during two spawning seasons (2004 and 2005), both in the field and in captivity. We show that animals in the field spawn approximately from mid-May through early July, but depending on the year, they show different patterns of spawning. Thus, even if temperature has a critical role in the induction of the spawning in captivity, it is not the major factor in the field. Moreover, we report some improvements on the methodology for inducing spawning in captivity (e.g. in maintenance, light cycle control and induction of spawning in a laboratory without running sea water system). These studies have important implications for amphioxus animal husbandry and for improving laboratory techniques to develop amphioxus as an experimental animal model. J. Exp. Zool. (Mol. Dev.

Résumé : A Lagrangian stochastic model is introduced in order to describe the local behavior of the wind. Based on some MM5 data, and thanks to particles driven by stochastic differential equations, we propose a numerical method allowing to improve the MM5 simulations at small scales, without requiring too much additional computational cost.

Résumé : The Radiation Transfer Model Intercomparison (RAMI) initiative benchmarks canopy reflectance models under well-controlled experimental conditions. Launched for the first time in 1999, this triennial community exercise encourages the systematic evaluation of canopy reflectance models on a voluntary basis. The first phase of RAMI focused on documenting the spread among radiative transfer (RT) simulations over a small set of primarily 1-D canopies. The second phase expanded the scope to include structurally complex 3-D plant architectures with and without background topography. Here sometimes significant discrepancies were noted which effectively prevented the definition of a reliable ''surrogate truth,'' over heterogeneous vegetation canopies, against which other RT models could then be compared. The present paper documents the outcome of the third phase of RAMI, highlighting both the significant progress that has been made in terms of model agreement since RAMI-2 and the capability of/need for RT models to accurately reproduce local estimates of radiative quantities under conditions that are reminiscent of in situ measurements. Our assessment of the self-consistency and the relative and absolute performance of 3-D Monte Carlo models in RAMI-3 supports their usage in the generation of a ''surrogate truth'' for all RAMI test cases. This development then leads (1) to the presentation of the ''RAMI Online Model Checker'' (ROMC), an open-access web-based interface to evaluate RT models automatically, and (2) to a reassessment of the role, scope, and opportunities of the RAMI project in the future.

Résumé : X-ray fluorescence (XRF) and X-ray diffraction (XRD) are necessary for complete identification of materials. Works of art and samples have to be carried to specialised laboratories for XRD analyses. In certain cases, this is uneasy or even infeasible. Fresco paintings or other artefacts with elevated security concerns cannot be moved, hence the interest of portable XRD. In the framework of the project EuArtech a portable XRF and XRD instrumentation has been developed. The instrument combines both XRF and XRD techniques in order to perform simultaneously elemental analysis and crystal structure identification. The system has a reasonable weight and requires low electrical power supply. In the present paper, the system design is shown and the first experimental results are discussed. They have been performed on paintings, glazes on ceramics and oxidized bronze. No damages have been detected on the analysed objects, even on paintings covered by varnish.

Résumé : Chronic nicotine exposure results in long-term homeostatic regulation of nicotinic acetylcholine receptors (nAChRs) that play a key role in the adaptative cellular processes leading to addiction. However, the relative contribution of the different nAChR subunits in this process is unclear. Using genetically modified mice and pharmacological manipulations, we provide behavioral, electrophysiological, and pharmacological evidence for a long-term mechanism by which chronic nicotine triggers opposing processes differentially mediated by beta2*- vs. alpha7*nAChRs. These data offer previously undescribed insights into the understanding of nicotine addiction and the treatment of several human pathologies by nicotine-like agents chronically acting on beta2*- or alpha7*nAChRs.

Résumé : It is most generally admitted that seimic ground motion is the convolution of source, path and site effects. The question addressed here is whether a fourth term, called "Site-City Interaction" (SCI), should be added for densely urbanized areas, corresponding to feedback effects from the shaken buildings in the soil. After a short overview of various, consistent observations, several specific experimental and numerical results are briefly summarized, that clearly evidence the wave radiation from isolated buildings and the possibilty of interactions between close buildings as well. The seismic response of a simple "city model" represented by a group of buildings is then addressed through a series of numerical simulations, which allow to determine under which conditions such SCI effects may be significant. These findings are consistent with a very simple "rule of thumb" approach based on the comparison between kinematic energies in soils and buildings, pointing to the significance of SCI effects for dense cities where building and soil periods coincide. The last section thus discusses the practical consequences of such SCI effects, and some possible directions to get unambiguous experimental evidence in real cities.
