Universal P Systems: One Catalyst Can Be Suficient
(Fénix Editora, 2013)
Whether P systems with only one catalyst can already be universal, is still an open problem. Here we establish universality (computational completeness) by using speci c variants of additional control mechanisms. At each ...

Studying the Chlorophyll Fluorescence in Cyanobacteria with Membrane Computing Techniques
(Fénix Editora, 2013)
In this paper, we report a pioneer study of the decrease in chlorophyll uorescence produced by the reduction of MTT (a dimethyl thiazolyl diphenyl tetrazolium salt) monitored using an epi uorescence microscope coupled ...

The "Catalytic Borderline" Between Universality and Non-Universality of P Systems
(Fénix Editora, 2013)
P systems are computing models inspired by the structure and the function- ing of the living cells; they are the basic computing devices of membrane computing, a branch of natural computing. The present note is an overview ...

Kernel P Systems - Version 1
(Fénix Editora, 2013)
A basic P system, called kernel P system4 (kP system for short), combining features of di erent P systems introduced and studied so far is de ned and discussed. The structure of such systems is de ned as a dynamic graph, ...

Simulating a Family of Tissue P Systems Solving SAT on the GPU
(Fénix Editora, 2013)
In order to provide e cient software tools to deal with large membrane systems, high-throughput simulators are required. Parallel computing platforms are good candidates, since they are capable of partially implementing ...

Analysing Gene Networks with PDP Systems. Arabidopsis thaliana, a Case Study
(Fénix Editora, 2013)
Gene Regulatory Networks (GRNs) are a useful tool for biologists to understand the interactions among genes in living organisms. A special kind of GRNs known as Logic Networks (LNs) has been recently introduced. These ...

Bridging Membrane and Reaction Systems - Further Results and Research Topics
(Fénix Editora, 2013)
This paper continues an investigation into bridging two research areas con- cerned with natural computing: membrane computing and reaction systems. More specif- ically, the paper considers a transfer of two assumptions/axioms ...

Rete Algorithm for P System Simulators
(Fénix Editora, 2013)
The Rete algorithm is a well-known algorithm in rule-based production systems which builds directed acyclic graphs that represent higher-level rule sets. This allows the rule-based systems to avoid complete re-evaluation ...

A GPU Simulation for Evolution-Communication P Systems with Energy Having no Antiport Rules
(Fénix Editora, 2013)
Evolution-Communication P system with energy (ECPe systems) is a cell- like variant P system which establishes a dependence between evolution and communi- cation through special objects, called `energy,' produced during ...
