Tissue P systems with cell division
(Agora University of Oradea, 2008)
In tissue P systems several cells (elementary membranes) communicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell–like) P systems with active membranes ...

Parallel Simulation of Probabilistic P Systems on Multicore Platforms
(Fénix Editora, 2012)
Ecologists need to model ecosystems to predict how they will evolve over time. Since ecosystems are non-deterministic phenomena, they must express the likelihood of events occurring, and measure the uncertainty of their ...

Membrane dissolution and division in P
(Springer, 2009)
Membrane systems with dividing and dissolving membranes are known to solve PSPACE problems in polynomial time. However, we give a P upperbound on an important restriction of such systems. In particular we examine systems ...

Modeling Signal Transduction Using P Systems
(Springer, 2006)
Cellular signalling pathways are fundamental to the control and regulation of cell behavior. Understanding of biosignalling network functions is crucial to the study of different diseases and to the design of effective ...

On spiking neural P systems
(Springer, 2010)
This work deals with several aspects concerning the formal verification of SN P systems and the computing power of some variants. A methodology based on the information given by the transition diagram associated with an ...

Simulation of Recognizer P Systems by Using Manycore GPUs
(Fénix Editora, 2009)
Software development for cellular computing is growing up yielding new applications. In this paper, we describe a simulator for the class of recognizer P systems with active membranes, which exploits the massively parallel ...

On the degree of parallelism in membrane systems
(Elsevier, 2007)
In the literature, several designs of P systems might be found for performing the same task. The use of different techniques or even different P system models makes it very difficult to compare these designs. In this ...

A Fast Solution to the Partition Problem by Using Tissue-Like P Systems
(IEEE Computer Society, 2008)
Tissue-like P systems with cell division is a computing model in the framework of membrane computing based on the intercellular communication and cooperation between neurons. In such a model, the structure of the devices ...

Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems
(Fénix Editora, 2009)
It is well known that any irreducible and aperiodic Markov chain has exactly one stationary distribution, and for any arbitrary initial distribution, the sequence of distributions at time n converges to the stationary ...

A Membrane Computing View on Tumours
(2006)
In this paper we discuss about the potential usefulness of P systems as natural tools for modelling tumours. This is done both from a macroscopic point of view, by considering the tumour as a growing mass of cells, as ...
