Spontaneous contractility--mediated cortical flow generates cell migration in 3-dimensional environments
R. J. Hawkins, R. Poincloux, O. Bénichou +3
We present a generic model of cell motility generated by acto-myosin contraction of the cell cortex. We identify analytically dynamical instabilities of the cortex and show that th…
Response to targeted perturbations for random walks on networks
Vincent Tejedor, Olivier Bénichou, Raphael Voituriez +1
We introduce a general framework, applicable to a broad class of random walks on networks, that quantifies the response of the mean first-passage time to a target node to a local p…
Optimization of the residence time of a Brownian particle in a spherical subdomain
O. Bénichou, R. Voituriez
In this communication, we show that the residence time of a Brownian particle, defined as the cumulative time spent in a given region of space, can be optimized as a function of th…
Geometry-controlled kinetics
O. Bénichou, C. Chevalier, J. Klafter +2
It has long been appreciated that transport properties can control reaction kinetics. This effect can be characterized by the time it takes a diffusing molecule to reach a target -…
Facilitated diffusion of proteins on chromatin
O. Benichou, C. Chevalier, B. Meyer +1
We present a theoretical model of facilitated diffusion of proteins in the cell nucleus. This model, which takes into account the successive binding/unbinding events of proteins to…
First passage time distribution for a random walker on a random forcing energy landscape
Michael Sheinman, Olivier Bénichou, Raphaël Voituriez +1
We present an analytical approximation scheme for the first passage time distribution on a finite interval of a random walker on a random forcing energy landscape. The approximatio…
