DESCRIPTION:Division Control in Escherichia coli is Based on a Size-sensing
  rather than Timing Mechanism\nMarie Doumic-Jauffret (INRIA Rocquencourt)\
 nModels describing the growth of cell populations have  been developed bas
 ed on assumptions on the stochastic mechanisms underlying growth and divis
 ion at the single cell level. In particular\, two different models have be
 en widely used for decades\, assuming that cell division probability depen
 ds respectively on cell age (the renewal equation) or cell size (the size-
 structured or growth-fragmentation equation) - or both.\nWe confront these
  models with data on E. coli single cells growth\, and develop a new estim
 ation methodology\, based on nonparametric functional testing within the P
 DE models\, in order to test the hypothesis of an age-dependent versus siz
 e-dependent division rate. We conclude that in E. Coli\, the division is c
 ontrolled by a size-sensing rather than timing mechanism.\nThis is a joint
  work with L. Robert and M. Hoffmann.\n
