Quorum sensing P systems
This paper continues the investigation of population P systems model [F. Bernardini, M. Gheorghe, Population P systems, Journal of Universal Computer Science 10 (5) (2004) 509–539] by considering bacterium quorum sensing (QS) phenomena as the basis of the new approach. A new computational model called QS P system is introduced. It is proved that QS P systems are able to simulate counter machine...
متن کاملTowards a P Systems Pseudomonas Quorum Sensing Model
Pseudomonas aeruginosa is an opportunistic bacterium that exploits quorum sensing communication to synchronize individuals in a colony and this leads to an increase in the effectiveness of its virulence. In this paper we derived a mechanistic P systems model to describe the behavior of a single bacterium and we discuss a possible approach, based on an evolutionary algorithm, to tune its paramet...

متن کاملQuorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...
متن کاملQuorum sensing
although it is fair to say that the problem is still not solved. How is colour constancy achieved? It is still something of a mystery as to how your visual system achieves colour constancy, but scientists do agree that there is more than one mechanism involved. All mechanisms in some way require comparisons of the reflected light from different locations across the scene; colour constancy is a ...
