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...

It is known that P systems with two membranes and minimal symport/antiport rules are "almost" computationally complete as generators of number or vector sets. Interpreti...

Abstract. Further results on the study of the dynamics of HIV infection with grids of conformon-P systems are reported. This study clearly shows a subdivision in two phases of 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 ...
