Tissue P systems with cell division
(Agora University of Oradea, 2008)
In tissue P systems several cells (elementary membranes) communicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell–like) P systems with active membranes ...

Representations and characterizations of languages in Chomsky hierarchy by means of insertion-deletion systems
(World Scientific, 2008)
Insertion-deletion operations are much investigated in linguistics and in DNA computing and several characterizations of Turing computability were obtained in this framework. In this note we contribute to this research ...

Handling Languages with Spiking Neural P Systems with Extended Rules
(Romanian Academy, Section for Information Science and Technology, 2006)
We consider spiking neural P systems with spiking rules allowed to introduce zero, one, or more spikes at the same time. A tool-kit for computing (some) operations with languages generated by such systems is provided. ...

Spiking neural P systems with extended rules: universality and languages
(Springer, 2008)
We consider spiking neural P systems with rules allowed to introduce zero, one, or more spikes at the same time. The motivation comes both from constructing small universal systems and from generating strings; previous ...
