Client–Server P Systems in Modeling Molecular Interaction

Abstract

Abstract. We present a new version of P systems called Client-Server P Systems (CSPS). The client membranes are characterized by their states; the server membrane stores the states of the clients and triggers the corresponding interaction rules. We show that CSPS have the same expressive power as Turing machines. CSPS is used to model various molecular processes in which interaction and state transitions are causally linked. Signaling pathways and T cell activation are described by using a CSPS software environment called MOlNET (MOlecular NETworks). MOlNET can describe the dynamics of molecular interactions, including both qualitative and quantitative aspects and simulating the signaling pathways that tune the activation thresholds for T cells.

Application Prospects of Metabolic P System / Metabolinės P Sistemos Taikymo Galimybės

“…A P system which uses classical evolution rules without communication targets is called Evolution-Communication P System (Cavaliere 2003). CSPS is a P system based on client and server membranes (Ciobanu et al 2003a). Self-activating P systems are used for solving NP complete problems (Czeizler 2003).…”

P Systems Running on a Cluster of Computers

“…The parallelism of P systems exists both between membranes (different reactions could take place in different molecules simultaneously), and within membranes (more than one reaction going on in one single membrane). Therefore P systems provide an ideal model for distributed and parallel algorithms [3,4]. Some implementations and simulators have been announced [1,5].…”
