Center node: "stochastic calculus of wrapped compartments"
  Abstract: The Calculus of Wrapped Compartments (CWC) is a variant of the Calculus of Looping Sequences(CLS). While keeping the same expressiveness, CWC strongly simpliﬁes the development of auto-matic tools for the analysis of biological systems. The main simpliﬁcation consists in the removal ofthe sequencing operator, thus lightening the formal treatment of the patterns to be matched in a term(whose complexity in CLS is strongly affected by the variables matching in the sequences).We deﬁne a stochastic semantics for this new calculus. As an application we model the interac-tion between macrophages and apoptotic neutrophils and a mechanism of gene regulation in E.Coli.
