P Systems with Active Membranes, Without Polarizations and Without Dissolution: A Characterization of P
(Springer, 2005)
We study the computational efficiency of recognizer P systems with active membranes without polarizations and without dissolution. The main result of the paper is the following: the polynomial computational complexity ...

Solving the BINPACKING Problem by Recognizer P Systems with Active Membranes
(Fénix Editora, 2004)
In this paper we present an e®ective solution to the BINPACKING problem using a family of recognizer P systems with active membranes, input membrane and external output. The analysis of the solution presented here will ...

A Study of the Robustness of the EGFR Signalling Cascade Using Continuous Membrane Systems
(Springer, 2005)
Many approaches to anticancer treatment have had a limited success. A fundamental hurdle to cancer therapy is the robustness of the signalling networks involved in tumourgenesis. The complexity of net- works of biological ...

On P Systems with Bounded Parallelism
(IEEE Computer Society, 2005)
A framework that describes the evolution of P systems with bounded parallelism is de ned by introducing basic formal features that can be then integrated into a structural operational semantics. This approach investigates ...

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 ...

P Systems, a New Computational Modelling Tool for Systems Biology
(Springer, 2006)
In this paper we present P systems as a reliable computa- tional modelling tool for Systems Biology that takes into account the discrete character of the quantity of components of biological systems, the inherently ...

A Linear Solution of Subset Sum Problem by Using Membrane Creation
(Springer, 2005)
Membrane Computing is a branch of Natural Computing which starts from the assumption that the processes taking place in the compartmental structure of a living cell can be interpreted as computations. In this framework, ...

Simulating Avascular Tumors with Membrane Systems
(Fénix Editora, 2005)
Tumor growth has received a considerable attention by the scientific community. In the earliest stages of development, tumor growth seems to be regulated by direct diffusion of nutrients and wastes from and to surrounding ...

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 ...
