Symport/Antiport P Systems with Three Objects Are Universal
(IOS Press, 2005)
The operations of symport and antiport, directly inspired from biology, are already known to be rather powerful when used in the framework of P systems. In this paper we confirm this observation with a quite surpris- ing ...

Spike Trains in Spiking Neural P Systems
(World Scientific, 2006)
We continue here the study of the recently introduced spiking neural P systems, which mimic the way that neurons communicate with each other by means of short electrical impulses, identical in shape (volt- age), but ...

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 ...

Tissue P systems with channel states
(Elsevier, 2005)
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 ...

P systems with minimal parallelism
(Elsevier, 2007)
A current research topic in membrane computing is to find more realistic P systems from a biological point of view, and one target in this respect is to relax the condition of using the rules in a maximally parallel way. ...

Bounding the Indegree of Spiking Neural P Systems
(Turku Center for Computer Science, 2006)
We continue the search of normal forms for spiking neural P systems, and we prove that the indegree of such systems (the maximal number of incoming synapses of neurons) can be bounded by 2 without losing the computatio ...

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 ...

Recent Computability Models Inspired from Biology: DNA and Membrane Computing
(Universidad del País Vasco, 2003)
We briefly present two areas of natural computing, vividly investigated in the recent years: DNA computing and membrane computing. Both of them have the roots in cellular biology and are rather developed at the theoretical ...

Membrane computing: Brief introduction, recent results and applications
(Elsevier, 2006)
The internal organization and functioning of living cells, as well as their cooperation in tissues and higher order structures, can be a rich source of inspiration for computer science, not fully exploited at the present ...

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. ...
