A refinement of Cardelli’s brane calculus [1] is introduced where membrane actions are directed. This modification brings the language closer to biological membranes and also o...
This paper studies the (in)equational theory of simulation preorder and equivalence over the process algebra BCCSP. We prove that in the presence of a finite alphabet with at least...
In this paper we propose a technique for evaluating similarity of XML Schema fragments. Firstly, we define classes of structurally and semantically equivalent XSD constructs. Then...
The aim of the paper is to give a formal compositional semantics for Spiking Neural P systems (SNP systems) by following the Structural Operational Semantics (SOS) approach. A pro...
