Building upon the known generalized-quantifier-based first-order characterization of LOGCFL, we lay the groundwork for a deeper investigation. Specifically, we examine subclasses of LOGCFL arising from varying the arity and nesting of groupoidal quantifiers in first-order logic with linear order. Ou

β¦ Synopsis
On the basic representation of complex systems by probabilistic weighted, connected, directed acyclic graphs we discuss Zipf's law and the possibility of obtaining the critical complexities for the evolution of complex systems. The speculation for the critical complexity per feature in respect to the chance to preserve the minimal hierarchical structure of the complex system gives c0=l/21n2~re2~2.77 bit per feature. An exact analytic treatment later gives the value Co = ~rE/(61n2) ~ 2.37 bit per feature.

This paper gives some new logical characterizations of the class of rudimentary languages in the scope of descriptive complexity. These characterizations are based on a logic introduced by Parigot and Pelz to characterize Petri Net languages, and generalized quantiΓΏers of comparison of cardinality.
Modified prosthetic metalloporphyrin, having a total of eight carboxylate groups at the terminal of two peripheral propionate side chains, was inserted into apomyoglobin to yield a new reconstituted myoglobin. The cluster of substituted carboxylates acts as the binding domain for cationic compounds
