Computational efficiency of dissolution rules in membrane systems
(Taylor and Francis, 2006)
Trading (in polynomial time) space for time in the framework of membrane systems is not sufficient to efficiently solve computationally hard problems. On the one hand, an exponential number of objects generated in ...

On the efficiency of cell-like and tissue-like recognizing membrane systems
(Wiley, 2009)
Cell-like recognizing membrane systems are computational devices in the framework of membrane computing inspired from the structure of living cells, where biological membranes are arranged hierarchically. In this paper ...

Cellular modelling using P systems and process algebra.
(Taylor and Francis Online, 2007)
In this paper various molecular chemical interactions are modelled under different computational paradigms. P systems and -calculus are used to describe intra-cellular reactions like protein-protein interactions and ...

A uniform solution to SAT using membrane creation
(Elsevier, 2007)
In living cells, new membranes are produced basically through two processes: mitosis and autopoiesis. These two processes have inspired two variants of cell-like membrane systems, namely P systems with active membranes ...

Modelling gene expression control using P systems: The Lac Operon, a case study
(Elsevier, 2008)
In this paper P systems are used as a formal framework for the specification and simulation of biological systems. In particular, we will deal with gene regulation systems consisting of protein–protein and protein–DNA ...

A Model of the Quorum Sensing System in Vibrio fischeri Using P Systems
(MIT Press, 2008)
Quorum sensing is a cell density dependent gene regulation system that allows an entire population of bacterial cells to communicate in order to regulate the expression of certain or specific genes in a coordinated way ...

Simulating FAS-induced apoptosis by using P systems
(Taylor and Francis Online, 2007)
In contrast to differential equations, P systems are an unconven- tional model of computation which takes into consideration the discrete character of the quantity of components and the inherent randomness that exists ...

How to express tumours using membrane systems
(ELSEVIER SCIENCE INC, 2007)
In this paper we discuss the potential usefulness of membrane systems as tools for modelling tumours. The approach is followed both from a macroscopic and a microscopic point of view. In the first case, one considers the ...
