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 ...

Computing Using Signals: From Cells to P Systems
(Fénix Editora, 2004)
In cell biology one of the fundamental topic is the study of how biological signals are managed by cells. Signals can arise from inside the cell or from the external environment and the correct answer to certain signals ...

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 ...

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 ...

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 { ...

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 ...

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 ...

A Java Simulator for Basic Transition P Systems
(Fénix Editora, 2004)
In this paper, a software tool (called SimCM, from Spanish Sim- ulador de Computaci¶on con Membranas) for handling P systems is presented. The program can simulate basic transition P Systems where dissolution of membranes ...

Size and Power of Extended Gemmating P Pystems
(Fénix Editora, 2004)
In P systems with gemmation of mobile membranes were ex- amined. It was shown that (extended) systems with eight membranes are as powerful as the Turing machines. Moreover, it was also proved that extended gemmating P ...

P Systems with Antiport Rules for Evolution Rules
(Fénix Editora, 2004)
We investigate a variant of evolution-communication P systems where the computation is performed in two substeps. First, all possible an- tiport rules are applied in a non-deterministic, maximally parallel way, ...
