Prof. Ulrich Gerland (LMU)23/05/2013, 09:00Enzymes within biochemical pathways are often colocalized, yet the consequences of specific spatial enzyme arrangements remain poorly understood. We study the impact of enzyme arrangement on reaction efficiency within a reaction-diffusion model. The optimal arrangement transitions from a cluster to a distributed profile as a single parameter, which controls the probability of...Go to contribution page

Prof. Andre S. Ribeiro (TUT)23/05/2013, 09:45Recent developments of single molecule detection techniques have made possible to observe transcription and translation, one event at a time, in live cells. Here, we report measurements of time intervals between consecutive transcription events from several promoters in live Escherichia coli cells, which were obtained using a single-RNA detection technique by MS2-GFP tagging....Go to contribution page

Prof. Chris Watkins (Royal Holloway)23/05/2013, 10:45Evolution by natural selection is a learning algorithm of remarkable power. We propose a simple, general abstract model of evolution for which the mutation-selection equilibrium can be given in closed form for arbitrary fitness functions. The model is a modification of the Moran process for evolution with overlapping generations.
Computational models of evolution -- such as... Go to contribution page -
Prof. Vincent Hakim (ENS)23/05/2013, 11:30In different biological processes, cells move in a coordinated way. Several experiments have quantitatively investigated this phenomenon. We will describe a simple model of interacting random walkers that we have developed to phenomenologically describe these results, based on data obtained in P Silberzan's lab (Institut Curie, Paris). The model serves to suggest some biological...Go to contribution page
