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 ...

Deductive Databases and P Systems
(Fénix Editora, 2004)
In computational processes based on backwards chaining, a rule of the type A Ã B1; : : : ;Bn is seen as a procedure which points that the problem A can be split into the problems B1; : : : ;Bn. In classical devices, the ...

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 ...

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, ...

An Approach to Computational Complexity in Membrane Computing
(Springer, 2005)
In this paper we present a theory of computational complexity in the framework of membrane computing. Polynomial complexity classes in recognizer membrane systems and capturing the classical deterministic and non-deterministic ...

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 ...
