Tissue-like P Systems with Channel-States
(Fénix Editora, 2004)
We consider tissue-like P systems with states associated with the links (we call them synapses) between cells, controlling the passage of objects across the links. We investigate the computing power of such devices for ...

P Systems: from Anti-Matter to Anti-Rules
(Escuela Técnica Superior de Ingeniería Informática, Universidad de Sevilla, 2019)
The concept of a matter object being annihilated when meeting its corresponding anti-matter object is taken over for rule labels as objects and anti-rule labels as the corresponding annihilation counterpart in P systems. ...

Polarizationless P Systems with One Active Membrane
(Fénix Editora, 2015)
The aim of this paper is to study the computational power of P systems with one active membrane without polarizations. For P systems with active membranes, it is known that computational completeness can be obtained with ...

Purely Catalytic P Systems over Integers and Their Generative Power
(Fénix, 2016)
We further investigate the computing power of the recently introduced P systems with Z-multisets (also known as hybrid sets) as generative devices. These systems apply catalytic rules in the maximally parallel way, even ...

Computational Completeness of P Systems Using Maximal Variants of the Set Derivation Mode
(Fénix, 2016)
We consider P systems only allowing rules to be used in at most one copy in each derivation step, especially the variant of the maximally parallel derivation mode where each rule may only be used at most once. Moreover, ...

Two Universality Results for (Mem)Brane Systems
(Fénix Editora, 2006)
We prove that P systems with mate and drip operations and using at most five membranes during any step of a computation are universal. This improves a recent similar result from, where eleven membranes are used. The proof ...

Asynchronous and Maximally Parallel Deterministic Controlled Non-Cooperative P Systems Characterize NFIN coNFIN
(Fénix Editora, 2012)
Membrane systems (with symbol objects) are distributed controlled multiset processing systems. Non-cooperative P systems with either promoters or inhibitors (of weight not restricted to one) are known to be computationally ...

Extended Spiking Neural P Systems with White Hole Rules
(Fénix Editora, 2015)
We consider extended spiking neural P systems with the additional possibility of so-called \white hole rules", which send the complete contents of a neuron to other neurons, and we show how this extension of the original ...

One-Membrane P Systems with Activation and Blocking of Rules
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
We introduce new possibilities to control the application of rules based on the preceding applications, which can be de ned in a general way for (hierarchical) P systems and the main known derivation modes. Computational ...

Length P Systems with a Lone Traveler
(Fénix Editora, 2014)
In this paper we consider P systems with linear membrane structures (only one membrane is elementary) with at most one object. We raise and attack the question about the computational power of such systems, depending on ...
