We introduce in the P systems area a mechanism, inspired from neural-cell behavior, which controls computations by inhibiting and de-inhibiting evolution rules. We investigate the ...

We apply techniques from complexity theory to a model of biological cellular membranes known as membrane systems or P-systems. Like Boolean circuits, membrane systems are defined ...

In the present paper we propose a way to simulate Boolean gates and circuits in the framework of P systems with active membranes using inhibiting/de-inhibiting rules. This new appr...

Abstract. We prove that uniform and semi-uniform families of P systems with active membranes using only communication and nonelementary division rules are not computationally unive...

Some initial results on the study of conformon-P systems with negative values are reported. One model of these conformon-P systems is proved to be computationally universal while a...
