Magnetotactic Bacteria and Their Significance for P Systems and Nanoactuators
(Fénix Editora, 2007)
In the framework of the dialog between P systems and Microbiology, in this paper we focus on the magnetotactic behavior of magnetotactic bacteria, namely the orientation along the Earth’s geomagnetic field lines. Magnetic ...

On String Languages Generated by Spiking Neural P Systems
(Fénix Editora, 2006)
We continue the study of spiking neural P systems by considering these computing devices as binary string generators: the set of spike trains of halting computations of a given system constitutes the language generated ...

Deterministic Solutions to QSAT and Q3SAT by Spiking Neural P Systems with Pre-Computed Resources
(Fénix Editora, 2009)
In this paper we continue previous studies on the computational effciency of spiking neural P systems, under the assumption that some pre-computed resources of exponential size are given in advance. Specifically, we give ...

First Steps Towards a Geometry of Computation
(Fénix Editora, 2005)
We introduce a geometrical setting which seems promising for the study of computation in multiset rewriting systems, but could also be applied to register machines and other models of computation. This approach will be ...

A CLIPS Simulator for Recognizer P Systems with Active Membranes
(Fénix Editora, 2004)
In this paper we propose a new way to represent recognizer P systems with active membranes based on Production Systems techniques. This representation allows us to express the set of rules and the configurations in each ...

About the Efficiency of Spiking Neural P Systems
(Fénix Editora, 2009)
Spiking neural P systems were proved to be Turing complete as function computing or number generating devices. Moreover, it has been considered in several papers that spiking neural P systems are also computationally ...

Simulating Shuffle-Exchange Networks with P Systems
(Fénix Editora, 2004)
We present in this paper a simulation with P systems of the parallel architecture known as shuffle-exchange network. This will lead us to consider a new version of P systems with communication, for which the communicat ...

Reaction Cycles in Membrane Systems and Molecular Dynamics
(Fénix Editora, 2006)
We are considering molecular dynamics and (sequential) membrane systems from the viewpoint of Markov chain theory. The first step is to understand the structure of the configuration space, with respect to communicating ...

On Trace Languages Generated by Spiking Neural P Systems
(Fénix Editora, 2006)
We extend to spiking neural P systems a notion investigated in the “stan- dard” membrane systems: the language of the traces of a distinguished object. In our case, we distinguish a spike by “marking” it and we follow ...

Further Results on P Systems with Promoters/Inhibitors
(Fénix Editora, 2005)
The paper gives several results regarding P systems with non-cooperative rules and promoters/inhibitors at the level of rules. For the class of P systems using inhibitors, generating families of sets of vectors of numbers, ...
