Considered are the classes QL (quasilinear) and NQL (nondet quasllmear) of all those problems that can be solved by deterministic (nondetermlnlsttc, respectively) Turmg machines in time O(n(log n) ~) for some k Effloent algorithms have time bounds of th~s type, it is argued. Many of the "exhausUve search" type problems such as satlsflablhty and colorabdlty are complete in NQL with respect to reductions that take O(n(log n) k) steps This lmphes that QL = NQL iff satisfiabdlty is m QL CR CATEGORIES: 5.25
A correct interpretation of the genitive plural forms in Slavic and related languages requires a detailed chronological analysis of the material. At every stage of development we have to reckon with both phonetically regular and analogical forms. Analogy operates quite often along the same lines in different periods. Explaining an analogic change amounts to indicating a model, a motivation, and a stage of development for its effectuation. If one of these cannot be indicated, we must look for a phonetic explanation.
The morphology of the skeletal portions of the sting apparatus is described and compared in 63 genera of myrmicine ants in order to evaluate its taxonomic potential in this difficult subfamily. The survey covers about half of the myrmicine genera, and an but 3 small tribes (Ochetomyrmecini, Melissotarsini, Stegomyrmicini). Interspecific variation in the apparatus is described in a third of the genera examined. In addition, the sting apparatus of the primitive ponerine ant, Amblyopone pallipes is described for comparison with the primitive myrmicines; and the sting associated glands (poison gland, Dufour's gland) are illustrated for single species of Amblyopone, Basiceros, Monomorium, Aphaenogaster, Crematogasier, and Zacryptocerus.
