Underlying the notion of an automatic structure is that of a synchronously regular (s-regular for short) set of pairs of strings. Accordingly we consider s-regular preex-rewriting systems showing that even for fairly restricted systems of this form connu-ence is undecidable in general. Then a close correspondence is established between the existence of an automatic structure that yields a preex...

BACKGROUND There has been speculation that rest during the regular season for players in the National Basketball Association (NBA) improves player performance in the postseason. PURPOSE To determine whether there is a correlation between the amount of regular-season rest among NBA players and playoff performance and injury risk in the same season. STUDY DESIGN Cohort study; Level of evidenc...

In this paper we propose a simple fast-search VQ of the LSF’s to be used on top of the split VQ, that is, in each of the sub-vector domains. The main trait of the proposed method is that no suboptimal codebooks are used and there is no further reduction in performance. In each sub-vector domain, a full-size optimally trained codebook, typically of size 1024, is searched using a fastsearch algor...

Among ants, plesiobiotic associations are defined as occasional or regular nesting of heterospecific colonies in close proximity and without any biological interdependence. Habitats with a scarcity available microhabitats ecological dissimilarity between the involved species supposed to favor frequency plesiobiosis. In last review published on this topic, authors summarized all pairs reported l...

Rhythmic structure in speech is characterized by sequences of stressed and unstressed syllables. A large body literature suggests that speakers English attempt to achieve rhythmic harmony evenly distributing syllables throughout prosodic phrases. The question remains as how plan metrical during production whether it planned independently phonemes. To examine this, we designed a tongue twister t...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

For given nonnegative integers k and D , we consider the problem of determining n,(k, D ) , the smallest number n for which there exists a k-regular bipartite graph on n vertices with diameter D . We solve the problem for all pairs ( k , D ) with D + 2 (mod 4) and D + 3 (mod 4), for all pairs ( k , D ) with k even or k prime and D + 3 (mod 4), for all pairs with D I 9 or k I 4, and for a few ot...

Overlapping recombinant clones that encompass the insulin-like growth factor (IGF) I and II genes have been isolated from a human genomic DNA library. Each gene is present once per haploid genome; the IGF-I gene spans greater than 35 kilobase pairs (kbp) and the IGF-II gene is at least 15 kbp. The exon-intron organization of these genes is similar, each having four exons, which is one more than...

in this article we study two different generalizations of von neumann regularity, namely strong topological regularity and weak regularity, in the banach algebra context. we show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. then we consider strong topological regularity of certain concrete algebras. moreover we obtain ...

in this paper we construct antimagic labelings of the regular complete multipartite graphs and we also extend the construction to some families of regular graphs.
