Metabolic P systems (MP systems) represent metabolic processes in a discrete mathematical framework based on P systems. MP systems are presented, with a special emphasis to their roots and to their relationship with P systems, which provided the right conceptual framework for their development. A synthetic algebraic formulation of MP system is given, and the log-gain theory of MP systems is out...
We consider extended variants of spiking neural P systems and show how these extensions of the original model allow for easy proofs of the computational completeness of extended spiking neural P systems and for the characterization of semilinear sets and regular languages by finite extended spiking neural P systems (defined by having only finite checking sets in the rules assigned to the cells)...
We propose a new variant of P Systems, based on boundary rules, shortly called PB Systems. Boundary rules means that rules are not internal to regions but they are able to “see” even externally, that is, they are sensible to what happens around the border of the membranes. We prove the computational universality for PB systems with three membranes which sense at most one symbol outside and one ...
Recent research in membrane computing examines and confirms the anticipated modelling potential of kernel P systems in several case studies. On the one hand, this computational model is destined to be an abstract archetype which advocates the unity and integrity of P systems onto a single formalism. On the other hand, this envisaged convergence is conceived at the expense of a vast set of primi...
We further investigate the parallel array P systems recently introduced by K.G. Subramanian, P. Isawasan, I. Venkat, and L. Pan. We first make explicit several classes of parallel array P systems (with one or more axioms, with total or maximal parallelism, with rules of various types). In this context, some results from the above mentioned paper by Subramanian et al. are improved. A series of o...

In the context of a compositional theory of automata [8] (CP automata) we define a notion of hierarchical automaton, and show how the P-systems of Gh. Păun [9] may be described in terms of these automata. A distributive law for CP automata is proved which relates two different views of hierarchical systems: the first view is that hierarchical systems consist of layers, with communication betwee...
