завтра в 9-30 коллега будет про генетические networks рассказывать. Ета муть вставляет не хуже старбакского пол-литры.

The window at the edge of chaos in a simple model of gene interaction networks

The model is based on experimentally motivated interaction network topologies, and is designed to capture some key statistics of gene expression statistics. We impose a non-linearity to the system by a boundary condition which guarantees non-negative concentrations of chemical concentrations and study the system stability quantified by maximum Lyapunov exponents . We find that the
non-negativity constraint leads to a drastic inflation of those regions in parameter space where the Lyapunov exponent exactly vanishes. We explain the finding as a self-organized critical phenomenon.
