    Vendredi 10 janvier 2014 11:00-12:00 - Bureau d'Etudes
    Quasi-long range order and sub-diffusion in systems of active particles in heterogeneous media
    The rapidly expanding study of active particles has focused so far almost exclusively, theoretically as well as experimentally, on the statistical description of particle motion in idealized, homogeneous spaces. However, the great majority of natural active particle systems takes place, in the wild, in (...)

    Transition from static to kinetic friction : insights from numerical experiments
    The contact between macroscopic rough solids is made of many micrometric asperities in contact. Under increasing shear force, each microcontact deforms, reaches its breaking threshold, and triggers a local micro-slip event. In some conditions, such an event can destabilize neighbouring microcontacts and a (...)
  • Yohann Duguet (LIMSI-CNRS, Orsay)
    Vendredi 24 janvier 2014 11:00-12:00 - Bureau d'Etudes
    Transition à la turbulence dans l'écoulement de Couette plan
    L'écoulement de Couette plan correspond à l'écoulement de fluide incompressible entre deux plaques parallèles qui cisaillent le fluide de façon homogène. Cet écoulement est, avec la transition dans les écoulements de type Poiseuille plan ou cylindrique, un prototype de la transition à la turbulence dite (...)

    Vendredi 7 février 2014 11:00-12:00 - Amphi Langevin (Bât N, 2ème étage)
    Contraction driven cell crawling
    The two main active processes allowing cells to crawl are myosin contraction and actin polymerization. We first show that these two mechanisms are complimentary allowing cells to handle such fundamentally different tasks as pushing and pulling. Then we focus on contraction dominated crawling involved, for (...)
  • Jeff Porter (Universidad Politécnica de Madrid)
    Vendredi 14 février 2014 11:00-12:00 - Bureau d'Etudes
    Vibrated fluids : Faraday waves, cross-waves, and vibroequilibria
    The behavior of vibrated fluids and, in particular, surface or interfacial instabilities, has been the subject of continued experimental and theoretical attention since Faraday's seminal experiments in 1831. Both orientation and frequency are critical in determining the response of the fluid to excitation. Low (...)
  • Jacopo Seiwert (IPR, Rennes)
    Vendredi 21 février 2014 11:00-12:00 - A4 (Langevin)
    Generation and deformation of soap films
    Liquid foams are widely used in industry for their high effective viscosity, whose local origin is still unclear. We present new theoretical and experimental results on the physics of soap films, in configurations mimicking the elementary deformation occurring during foam shearing. Theoretically, we study the (...)

    Comprendre les sciences...
    Si je suis le déroulé d'une démonstration abstraite, du théorème initial aux conclusions, ai-je compris le phénomène qu'elles illustrent ? A l'inverse, peut-on comprendre les phénomènes de la nature et de l'univers sans connaissance scientifique ? Au-delà de l'approche qualitative des phénomènes, peut-on parler d'approche (...)

    Biomechanics and evolution in snakes
    Morphological convergence as a consequence of extreme functional demands : examples from the feeding system of natricine snakes Despite repeated acquisitions of aquatic or semi-aquatic lifestyles revolving around piscivory, snakes have not evolved suction feeding. Instead, snakes use frontally or laterally (...)

Information for the speakers

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
