  • Fernando Peruani (Universite de Nice Sophia Antipolis)
    Lundi 29 octobre 2012 11:15-12:15 - Bibliothèque PCT - F3.04
    From bacteria to collective motion in heterogeneous media
    First part - I will show some recent experimental results with three mutants of the gliding bacterium Myxococcus xanthus. We found that mutants lacking biochemical signaling and moving unidirectionally exhibit collective motion in the form of large moving clusters at intermediate densities, while self-organize (...)

    Equilibrium and non-equilibrium statistical physics of the power stroke in skeletal muscles
    The classical Huxley-Simmons model of muscle contractions exhibits unusual statistical properties due to the presence of long range elastic interactions. Those include non-equivalence of the soft and hard device ensembles, negative equilibrium stiffness and anomalously slow kinetics in the soft device. Our (...)

    Lundi 19 novembre 2012 11:15-12:15 - Bibliothèque PCT - F3.04
    Dynamics and hydrology of rapid ice sheet motion
    Two questions are discussed which arise in evaluating possible scenarios of accelerated deglaciation in Greenland and Antarctica.

    Role of sleep in memory processes
    The two-stage model of memory consolidation developed by Gyorgy Buzsaki proposed that encoding occurs during awake hippocampal theta oscillations (5-10Hz) and consolidation during slow wave sleep (SWS), involving reactivations that occur during hippocampal 200Hz oscillations called the sharp-waves-ripples (...)

    Lundi 17 décembre 2012 11:15-12:15 - Bibliothèque PCT - F3.04
    A simple force-motion relationship of migrating cells
    In this talk, we would discuss about a force-motion relationship of migrating eukaryotic adherent cells. Biological cells migrate without net forces, which is a consequence of force-free and negligible inertia conditions (Purcell, 1977). This indicates that to elucidate a force-motion relationship, unlike in cases (...)

    Lundi 7 janvier 2013 11:15-12:15 - Bibliothèque PCT - F3.04
    Understanding and manipulating microbubble streaming flows : size-sensitive sorting and mixing
    Ultrasound-induced oscillation of microbubbles gives rise to intense, steady streaming flows. We show that the flow patterns can be flexibly and interactively shaped by the superposition of a transport flow and adjustment of driving amplitude and/or frequency. In this way, sensitive selection, focusing, and (...)

    Investigating mechanical properties of disordered solids with computer simulations
    Many solids around us are disordered : glassy or semi crystalline polymers, oxide or metallic glasses, nanocomposites, are common examples. In disordered systems, the link between macroscopic mechanical properties and the nanostructure of the materials is far from being understood. I will describe some of the (...)

General recommendations for the speakers

The audience is often heterogeneous - because of the wide range of scientific topics covered in the lab - so planning a talk for a broader audience would be preferred. The seminar is in English, and speakers are thus invited to prepare their slides in English.

The seminar starts at 11:30 AM. The speaker is asked to arrive in the lab at least 15 minutes in advance to set up their computer. The talks last typically 45 minutes, and are followed by a discussion time.
