Processes of membrane systems with promoters and inhibitors
Membrane systems (with promoters and inhibitors) are a computational model inspired by the way living cells are divided by membranes into compartments where chemical reactions may take place. We consider synchrony and asynchrony between executed reactions in the computations of such systems using Petri nets and their processes as a formal behavioural model. We first discuss different definition...
متن کاملOn P Systems with Promoters/Inhibitors
This article shows how the computational universality can be reached by using P systems with object rewriting context-free rules, promoters/inhibitors and one catalyst. Both generative and accepting cases are studied. Some examples that illustrate the theoretical issues are also presented.
متن کاملFurther results on P systems with promoters/inhibitors
The paper gives several results regarding P systems with non-cooperative rules and promoters/inhibitors at the level of rules. For the class of P systems using inhibitors, generating families of sets of vectors of numbers, the equivalence with the family of Parikh sets of ET0L languages is presented. In case of P systems with noncooperative promoted rules even if an upper bound was not given, t...
متن کاملPriorities, Promoters and Inhibitors in Deterministic Non-cooperative P Systems
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 complete. Since recently, it is known that the power of the deterministic subclass of such systems is subregular. We present new results on the weight of promoters and inhibi...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
