In this paper, we introduce the notion of k-comma codes a proper generalization of the notion of comma-free codes. For a given positive integer k, a k-comma code is a set L over an alphabet Σ with the property that LΣL ∩ ΣLΣ = ∅. Informally, in a k-comma code, no codeword can be a subword of the catenation of two other codewords separated by a “comma” of length k. A k-comma code is indeed a cod...

The Scientific Leadership Scholars (SLS) Program is an NSF S-STEM sponsored scholarship for financially and academically eligible students in Computer Science, Environmental Resources Engineering and Mathematics at Humboldt State University. The scholarship has sponsored 57 students in these majors over the past 4 years. Of these students, 54% were underrepresented minorities and 70% were under...

a localized pretibial accumulation of mucin under the skin is not found in myxcedema, but for want of a proper name and in order to facilitate reference to earlier literature, the name has been retained. It has been suggested by Webber (1937) that the word myxcedema should be in inverted commas. Trotter and Eden (1942) have recently reviewed 73 cases of this condition mentioned in literature, a...

0003-3472 2013 The Authors. Published on behalf http://dx.doi.org/10.1016/j.anbehav.2013.10.003 Distractive marks have been suggested to prevent predator detection or recognition of a prey, by drawing the attention away from recognizable traits of the bearer. The white ‘comma’ on the wings of comma butterflies, Polygonia c-album, has been suggested to represent such a distractive mark. In a lab...

Coordination has always been a difficult phenomenon, with regard to linguistic analysis, manual annotation, and automatic analysis. There is a considerable body of work on detecting coordination and on improving parsing for this phenomenon. However, most approaches were restricted to certain types of coordination, such as NP coordination or symmetrical coordination. We present the first approac...

Nets, useful topological tools, used to generalize certainconcepts that may only be general enough in the context of metricspaces. In this work we introduce this concept in an $S$-poset, aposet with an action of a posemigroup $S$ on it whichis a very useful structure in computer sciences and interestingfor mathematicians, and give the the concept of $S$-net. Using $S$-nets and itsconvergency we...
