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 ...

Languages and P systems: Recent developments
(2012)
Languages appeared from the very beginning in membrane computing, by their length sets or directly as sets of strings. We briefly recall here this relationship, with some details about certain recent developments. In ...

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 automata revisited
(Elsevier, 2012)
We continue here the investigation of P automata, in their non-extended case, a class of devices which characterize non-universal family of languages. First, a recent conjecture is confirmed: any recursively enumerable ...

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. ...

Spiking Neural P systems with several types of spikes
(Agora University of Oradea, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

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 ...
