9:00 General architecture of a genetic regulation network: Applications to embryologic and immunologic control The general architecture of a genetic regulation network consists of strong connected components of its interaction graph, to which are attached three kinds of sub-structures. (1) A set of up-trees, issued from the sources of the interaction graph of the network, made either of small RNAs or of genes repressors and/or inductors, self-expressed without any other genes controlling them. (2) A set of circuits in the core (in graph sense) of the strong connected components of the interaction graph. (3) A set of down-trees going to the sinks of the interaction graph, i.e., to genes controlled, but not controlling any other genes. The various state configurations it is possible to observe in the above sub-structures correspond to different dynamical behaviours. We show that these dynamics have in general a small number of attractors, corresponding to the functions of the tissue they represent in the Delbrück’s paradigm. Examples of such dynamics will be given in embryology (feather morphogenesis in chicken, gastrulation and wings morphogenesis in Drosophila) as well as in immunology (rearrangements of the genes of the TCRα receptors in mice).

12:10 Proposals for the 2013 European Conference on Artificial Life As ECAL’11 is drawing to a close, we are glad to announce a bid process for the organization of the next ECAL in 2013. We invite anyone interested in hosting this event to prepare a 1- or 2-page PDF proposal. This flyer should specify the venue and date and contain the most relevant information highlighting your proposal. Please email your ECAL’13 flyer to Hugues Bersini, Paul Bourgine and René Doursat by Thursday, August 11 at the latest. You should also prepare a 5-10mn slideshow to present during this bid session. The final decision will be made the same day through a voting procedure among the board members of the International Society of Artificial Life (ISAL), together with the main organizers of previous Alife and ECAL conferences present at ECAL’11.
