Reaction Cycles in Membrane Systems and Molecular Dynamics
(Fénix Editora, 2006)
We are considering molecular dynamics and (sequential) membrane systems from the viewpoint of Markov chain theory. The first step is to understand the structure of the configuration space, with respect to communicating ...

Some Notes on the Interplay Between P Systems and Chemotaxis in Bacteria
(Fénix Editora, 2006)
We describe some chemotactic behaviors of bacteria, that is, their movement response to changes in the environment, and the underlying molecular mechanisms. We outline how such processes could be linked to membrane ...

Two Universality Results for (Mem)Brane Systems
(Fénix Editora, 2006)
We prove that P systems with mate and drip operations and using at most five membranes during any step of a computation are universal. This improves a recent similar result from, where eleven membranes are used. The proof ...

Stochastic Approaches in P Systems for Simulating Biological Systems
(Fénix Editora, 2006)
Different stochastic strategies for modeling biological systems with P systems are reviewed in this paper, such as the multi-compartmental approach and dynamical probabilistic P systems. The respective results obtained ...
