International audience; Songs constitute a natural combination of lyrics and melodies, but it is unclear whether and how these two song components are integrated during the emergence of a memory trace. Network theories of memory suggest a prominent role of the hippocamp...

Summary Context By contrast with the glial scar, myelin was considered a constitutive static inhibitory barrier unreactive to lesions in the central nervous system (CNS). However, recent results suggest considerable add-on inhibition of myelin as a result of CNS injury....

National audience; Voyager à l’intérieur du corps humain, observer le mouvement de l’air dans les poumons ou encore voir la poussée du sang gonfler les artères au rythme des battements du cœur... Grâce aux modélisations infomatiques, c’est maintenant possible.

International audience; Monthly averaged level-3 SeaWiFS chlorophyll concentration data from 1998 to 2001 are globally analyzed using Fourier's analysis to determine the main patterns of temporal variability in all parts of the world ocean. In most regions, seasonal var...

International audience; This work describes an immunological method for detection and quantification in complex environments of the dissimilative nitrate reductase (NRA) responsible for the reduction of nitrate to nitrite, which plays an important role in ecosystem func...

We present an extensive analysis of the Raman spectrum of ammonia IV, for both ${\mathrm{NH}}_{3}$ and ${\mathrm{ND}}_{3}$, between 6 and $11\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$. Polarized Raman scattering experiments were performed at low temperature $(20--80\phant...

National audience; Pour les instruments de musiquè a vent, l'inharmonicité des fréquences de résonance est une des grandeurs considérées , en facture instrumentale, comme représentatives de la qualité d'un instrument. L'inharmonicité peut altérer le timbre ainsi que la ...

16 pages; In this paper we tackle the asymptotics of the critical dimension for quadratic functional quantization of Gaussian stochastic processes as the quantization level goes to infinity, $i.e.$ the smallest dimensional truncation of an optimal quantization of the pr...

The development of fractures in the sedimentary layers of Sheep Mountain Anticline, a Laramide asymmetric fault-cored fold of the Bighorn Basin, is documented and interpreted to constrain the kinematic evolution of the fold. The fracture pattern is interpreted to identi...

International audience; A simple dynamical cascade model for the evolution of free energy is considered in the context of gyrokinetic formalism. It is noted that the dynamics of free energy, that characterize plasma micro-turbulence in magnetic fusion devices, exhibit a...
