P Systems with Active Membranes and Without Polarizations
(Fénix Editora, 2004)
P systems with active membranes but without using electrical charges (polarizations) are shown to be complete for generating recursively enumerable string languages when working on string objects and using only rules ...

Communication and Stochastic Processes in Some Bacterial Populations: Significance for Membrane Computing
(Fénix Editora, 2009)
Intercellular communication between bacterial cells belonging to the same population is well documented in Microbiology, sporulation and cannibalism in B. Subtilis and genetic competence and fratricide in S. pneumoniae ...

A Biological Perspective on Sorting with P Systems
(Fénix Editora, 2008)
The aim of this contribution is to argue that the processes occurring in biological membranes in bacteria are also important as natural examples of communication between membranes, which, in the formal framework of P ...

Looking for P Truth
(Fénix Editora, 2004)
In a general sense, Logic studies how to derive new pieces of in- formation from previous ones. In this paper we explore the analogies between P systems, where new configurations can be obtained from previous ones by using ...

Mutual Mobile Membranes Systems with Surface Objects
(Fénix Editora, 2009)
In this paper we introduce mutual mobile membranes with surface objects, systems which have biological motivation. In P systems with mobile membranes with surface objects, a membrane may enter or exit another membrane. ...

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.

Introducing a Space Complexity Measure for P Systems
(Fénix Editora, 2009)
We define space complexity classes in the framework of membrane computing, giving some initial results about their mutual relations and their connection with time complexity classes, and identifying some potentially ...

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 ...

On Modeling Signal Transduction Networks
(Fénix Editora, 2008)
Signal transduction networks are very complex processes employed by the living cell to suitably react to environmental stimuli. Qualitative and quantitative computational models play an increasingly important role in the ...

Extended Spiking Neural P systems with Excitatory and Inhibitory Astrocytes
(Fénix Editora, 2007)
We investigate an extended model of spiking neural P systems incorporating astrocytes and their excitatory or inhibitory influence on axons between neurons. Using very restricted variants of extended spiking neural P ...
