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 ...

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 ...

On Descriptive Complexity of P Systems
(Springer, 2005)
In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where the number of steps of a computation ...

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 ...

A Linear-Time Solution to the Knapsack Problem Using P Systems with Active Membranes
(Springer, 2004)
Up to now, P systems dealing with numerical problems have been rarely considered in the literature. In this paper we present an effective solution to the Knapsack problem using a family of deterministic P systems with ...

An Efficient Cellular Solution for the Partition Problem
(Fénix Editora, 2004)
Numerical problems are not very frequently addressed in the P sys- tems literature. In this paper we present an e®ective solution to the Partition problem via a family of deterministic P systems with active membranes ...

Computing Partial Recursive Functions by Transition P Systems
(Springer, 2004)
In this paper a variant of transition P systems with external output designed to compute partial functions on natural numbers is presented. These P systems are stable under composition, iteration and unbounded minimization ...

A fast P system for finding a balanced 2-partition
(Springer, 2005)
Numerical problems are not very frequently addressed in the P systems literature. In this paper we present an effective solution to the 2-Partition problem via a family of deterministic P systems with active membranes ...
