P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

Small Universal Spiking Neural P Systems
(Fénix Editora, 2006)
In search for small universal computing devices of various types, we consider here the case of spiking neural P systems (SN P systems), in two versions: as devices computing functions and as devices generating sets of ...

Event-Related Outputs of Computations in P Systems
(Fénix Editora, 2005)
We briefly investigate the idea to consider as the result of a computation in a P system the number of steps elapsed between two events produced during the computation. Specifically, we first consider the case when the ...

Research Topics Arising from the (Planned) P Systems Implementation Experiment in Technion
(Fénix Editora, 2008)
We formulate here a few technical (mathematical) open problems related to the in vitro bio-chemical experiment planned in Technion for computing the Fibonacci sequence in terms of P systems. So-called local-loop-free P ...

Further Twenty Six Open Problems in Membrane Computing
(Fénix Editora, 2005)
This is a sort of personal list of problems and research topics, compiled with the occasion of the Third Brainstorming Week on Membrane Computing, Sevilla, 2005.

Polarizationless P Systems with Active Membranes Working in the Minimally Parallel Mode
(Fénix Editora, 2007)
We investigate the computing power and the efficiency of P systems with active membranes without polarizations, working in the minimally parallel mode. We prove that such systems are computationally complete and able to ...

Tissue P Systems with Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

New Normal Forms for Spiking Neural P Systems
(Fénix Editora, 2009)
We consider a natural restriction in the architecture of a spiking neural P system, namely, to have neurons of a small number of types (i.e., using a small number of sets of rules), and we prove that three types of neurons ...

Spiking Neural P Systems with Anti-Spikes
(Fénix Editora, 2009)
Besides usual spikes employed in spiking neural P systems, we consider "anti-spikes", which participate in spiking and forgetting rules, but also annihilate spikes when meeting in the same neuron. This simple extension ...
