Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

Looking for Simple Common Schemes to Design Recognizer P Systems with Active Membranes That Solve Numerical Decision Problems
(Springer, 2005)
Earlier solutions to decision problems by means of P systems used many counter objects to control the synchronization of different stages in a computation (usually as many counters as the stage must last in the worst ...

A fast local algorithm for track reconstruction on parallel architectures
(IEEE Computer Society, 2019)
The reconstruction of particle trajectories, tracking, is a central process in the reconstruction of particle collisions in High Energy Physics detectors. At the LHCb detector in the Large Hadron Collider, bunches of ...

One and Two Polarizations, Membrane Creation and Objects Complexity in P Systems
(IEEE Computer Society, 2005)
We improve, by using register machines, some existing universality results for specific models of P systems. P systems with membrane creation are known to generate all recursively enumerable sets of vectors of non-negative ...

Computing Partial Recursive Functions by Virus Machines
(Springer, 2015)
Virus Machines are a computational paradigm inspired by the manner in which viruses replicate and transmit from one host cell to another. This paradigm provides non-deterministic sequential devices. Non-restricted Virus ...

A First Attempt to Model Notch Signalling by Means of P Systems
(Universidad de Sevilla, Departamento de Ciencias de la Computación e Inteligencia Artificial, 2009)
During mammalian central nervous system development, an enormous variety of cell types are generated. This cell diversity is due in part to asymmetrical cell division. Indeed, in some sense Notch signals link the fate ...

Tissue P Systems with Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...

Revisiting Sevilla Carpets: A New Tool for the P-Lingua Era
(Fénix Editora, 2014)
Sevilla Carpets have already been used to compare di erent solutions of the Subset Sum problem: either designed in the framework of P systems with active membranes (both in the case of membrane division and membrane ...
