In cell biology one of the fundamental topic is the study of how biological signals are managed by cells. Signals can arise from inside the cell or from the external environment and the correct answer to certain signals ...

We introduce a new variant of membrane systems where the rules are directly assigned to membranes (and not to the regions as this is usually observed in the area of membrane systems) and, moreover, every membrane carries ...

We investigate a variant of evolution-communication P systems where the computation is performed in two substeps. First, all possible an- tiport rules are applied in a non-deterministic, maximally parallel way, ...

The aim of this paper is to study the power of parallel multiset- rewriting systems with permitting context (or P systems with non-cooperative rules with promoters). The main result obtained is that if we use promoters of ...

In this paper we de¯ne a general class of P systems covering some biological operations with membranes, including evolution, communication, modifying the membrane structure, and we describe and formally specify some of ...

Two classes of tissue P systems based on evolution communication rules are introduced, some results are proved, but many more are listed as further research problems. A framework to develop population P systems is de¯ned ...

A formalization of Kauffman Boolean Networks in terms of P systems is suggested along two lines: by means of register machines and directly by means of membranes with receptors.

The usual assumption in P systems behavior is that of maximal parallelism, however in living cells it is not the case because they have a limited number of enzymes. The aim of this paper is to try to merge these ideas ...

In this paper we consider symport/antiport P systems with one membrane and rules having at most two objects. Although it has been proved that only finite number sets can be generated by both OP1(sym2) (one-membrane systems ...

The aim of this research is to produce an algorithm for the software that would let a researcher to observe the evolution of maximally parallel multiset-rewriting systems with permitting and forbidding contexts, browsing ...
