P systems with active membranes using only two electrical charges and only rules of type (a) , i.e., evolution rules used in parallel in the regions of the membrane system, and of ...

In the attempt to have a framework where the computation is done by communication only, we consider the biological phenomenon of trans-membrane transport of couples of chemicals (o...
