P Systems with Active Membranes and Without Polarizations
(Fénix Editora, 2004)
P systems with active membranes but without using electrical charges (polarizations) are shown to be complete for generating recursively enumerable string languages when working on string objects and using only rules ...

P Systems with Antiport Rules for Evolution Rules
(Fénix Editora, 2004)
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, ...

P Systems with Active Membranes and Two Polarizations
(Fénix Editora, 2004)
P systems with active membranes using only two electrical charges and only rules of types (a) and (c) assigned to at most two membranes are shown to be computationally complete { thus improving the previous result of ...

Tissue-like P Systems with Channel-States
(Fénix Editora, 2004)
We consider tissue-like P systems with states associated with the links (we call them synapses) between cells, controlling the passage of objects across the links. We investigate the computing power of such devices for ...

Sequential P Systems with Unit Rules and Energy Assigned to Membranes
(Fénix Editora, 2004)
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 ...
