Natural semantics,th its connections to ideas in logic and computing. Natural Semantics is of interest . and because it is used as a semantics specification formalism for an interactive computer system that we are currently building at INRIA.

On selecting the largest element in spite of erroneous information,ient to find the largest. If there is further restriction that errors are confined to “no” answers and that all “yes” answers are guaranteed to be correct, then 2.+2.−4 comparisons are sufficient. This contrasts with earlier results relating to errors in binary search procedures where both versions of the problem have the same complexity.

Some structural aspects of hypergraph languages generated by hyperedge replacement,r. The former is indicated, for example, by a pumping lemma, the latter by the examples (among them you find the refinement of Petri nets, the analysis of flow diagrams, the structural description of molecules and some typical non-context-free string languages).

Polynomial operations on rational languages,property. Our main result shows that if . is a boolean algebra closed under quotients then Pol(.) is closed under intersection. As an application, we refine the concatenation hierarchy introduced by Straubing and we show that the levels 1/2 and 3/2 of this hierarchy are decidable.

Both approaches are feasible, and each has its advantages and disadvantages for different applications. Stem cell cultures have been used in clinical studies to
