Membrane Systems with Symport/Antiport Rules: Universality Results,cules pass in the same direction, in the case of antiport two or more molecules pass in opposite directions. In this paper we first survey the results on the computing power of membrane systems (P systems) using only symport/antiport rules and then improve some of the results known so far. A recent

Simulating Counter Automata by P Systems with Symport/Antiport,ced if counter automata instead of matrix grammars are simulated. We consider both subsets of N obtained by counting objects in a designated membrane, and string languages obtained by following the traces of a designated object.

Membrane Systems and Distributed Computing,sponse system against virus attacks. The example is implemented using a P system library created by the authors to simulate the main functions of a P system, and an MPI program that takes advantage of the highly parallel features provided by the model. The program uses distributed leader election and synchronization algorithms.
