Abstract. Some decision problems related to balanced context-free languages are important for their application to the static analysis of programs generating XML strings. One such ...
Several proposals for updating XML have been introduced. Many of them have a rather complicated semantics due to the interaction of side-effects and updates, and some proposals a...
We consider spiking neural P systems with rules allowed to introduce zero, one, or more spikes at the same time. The motivation comes both from constructing small universal systems...

Systems of language equations of the form {ϕ(X1, . . . , Xn) = ∅, ψ(X1, . . . , Xn) = ∅} are studied, where ϕ, ψ may contain set-theoretic operations and concatenation; the...
Dependency-based representations of natural language syntax require a fine balance between structural flexibility and computational complexity. In previous work, several constra...
