P Systems with Boundary Rules
We propose a new variant of P Systems, based on boundary rules, shortly called PB Systems. Boundary rules means that rules are not internal to regions but they are able to “see” even externally, that is, they are sensible to what happens around the border of the membranes. We prove the computational universality for PB systems with three membranes which sense at most one symbol outside and one ...
متن کاملP Systems with Anti-Matter
After a short introduction to the area of membrane computing (a branch of natural computing), we introduce the concept of anti-matter in membrane computing. First we consider spiking neural P systems with anti-spikes, and then we show the power of anti-matter in cell-like P systems. As expected, the use of anti-matter objects and especially of matter/anti-matter annihilation rules, turns out to...
متن کاملP systems with minimal parallelism
A current research topic in membrane computing is to find more realistic P systems from a biological point of view, and one target in this respect is to relax the condition of using the rules in a maximally parallel way. We contribute in this paper to this issue by considering the minimal parallelism of using the rules: if at least a rule from a set of rules associated with a membrane or a regi...
متن کاملComputing Backwards with P Systems
Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made calculus by considering the specific features of the given configuration. In this paper we present a general method for characterizing all the configurations C′ such that pr...
متن کاملRNA Interference: Systemic RNAi SIDes with Endosomes
Systemic RNAi, the intercellular spreading of RNAi silencing, requires SID-1 and SID-3 to import silencing signals in Caenorhabditis elegans. How are these signals exported? SID-5, an endosome-associated protein, is a candidate for the job.
