Modeling Logic Gene Networks by Means of Probabilistic Dynamic P Systems
(Old City Publishing, 2013)
Gene regulatory networks are useful models for biologists to understand the interactions among genes in living organisms. In this work, we consider a special class of gene regulatory networks, called logical networks, ...

Spiking Neural P systems with several types of spikes
(Agora University of Oradea, 2011)
With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...

A computational modeling for real ecosystems based on P systems
(Springer, 2011)
In this paper, a P systems based general framework for modeling ecosystems dynamics is presented. Particularly, ecosystems are specified by means of multienvironment P systems composed of a finite number of environments, ...

Efficient simulation of tissue-like P systems by transition cell-like P systems
(Springer, 2009)
In the framework of P systems, it is known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP-complete problems. Nonetheless, it could be sufficient to create ...

Time-free solution to SAT problem using P systems with active membranes
(Elsevier, 2014)
P systems are a class of distributed and parallel computation models inspired by the structure and the functioning of living cells. P systems have been used to solve computation hard problems, where the execution of each ...

Analysis of P systems simulation on CUDA
(SARTECO: Sociedad de Arquitectura y Tecnología de Computadores, 2009)
GPUs (Graphics Processing Unit) have been con- solidated as a massively data-parallel coprocessor to develop many general purpose computations, and en- able developers to utilize several levels of parallelism to obtain ...

The role of integral membrane proteins in computational complexity theory
(Springer, 2018)
In the framework of Membrane Computing, several tools to tackle the P versus NP problems by means of frontiers of the efficiency expressed in terms of syntactic or semantic ingredients, have been developed. In this paper, ...

A Formalization of Transition P Systems
(IOS Press, 2002)
In this paper we give a complete formalization of a new computability model of a distributed parallel type which is inspired by some basic features of living cells: transition P systems as they were given in [3], addressed ...

Computational efficiency and universality of timed P systems with membrane creation
(Springer, 2015)
P systems are a class of distributed parallel computing models inspired by the structure and the functioning of a living cell, where the execution of each rule is completed in exactly one time unit (a global clock ...

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 ...
