Sleep-Awake Switch with Spiking Neural P Systems: A Basic Proposal and New Issues
(Fénix Editora, 2009)
Spiking Neural P Systems are a kind of Membrane Systems developed with the aim of incorporating ideas from biological systems, known as spiking neurons, in the computational field. Initially, these systems were designed ...

Computing Backwards with P Systems
(Fénix Editora, 2009)
Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made ...

Notch Signalling and Cellular Fate Choices: A Short Review
(Fénix Editora, 2009)
During mammalian central nervous system (CNS) development, an enormous variety of cell types are generated. This cell diversity is due in part to asymmetrical cell division. Asymmetrical segregation of Numb, a cell-determinant ...

The Discovery of Initial Fluxes of Metabolic P Systems
(Fénix Editora, 2009)
A central issue in systems biology is the study of efficient methods to infer fluxes of biological reactions starting from experimental data. Among the different techniques proposed in the last years, in the theory of ...

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 ...

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. ...

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 ...

On Very Simple P Colonies
(Fénix Editora, 2009)
We study two very simple variants of P colonies: systems with only one object inside the cells, and systems with insertion-deletion programs, so called P colonies with senders and consumers. We show that both of these ...

A Short Note on Reversibility in P Systems
(Fénix Editora, 2009)
Membrane computing is a formal framework of distributed parallel comput- ing. In this paper we study the reversibility and maximal parallelism of P systems from the computability point of view. The notions of reversible ...
