Time is a pervasive notion of high impact in information systems and computer science altogether. Respective understandings of the domain of time are fundamental for numerous areas, frequently in combination with closely related entities such as events, changes, and processes. The conception and representation of time entities and reasoning about temporal data and knowledge are thus significant...

We review and extend the results of [1] that give a condition for reducibility of quantum representations of mapping class groups constructed from Reshetikhin-Turaev type topological quantum field theories based on modular categories. This criterion is derived using methods developed to describe rational conformal field theories, making use of Frobenius algebras and their representations in mod...

The present study provides an empirical evaluation of the ideal representation view of concept representation. We compared the ideal representation view with the more established exemplar and prototype views both in common taxonomic categories and in ad hoc categories. All three views are modeled based on underlying spatial similarity representations. Results suggest that the ideal representati...

this study aimed to examine the relationship between pigments and seed fall rate of iranian castor genotypes and genetic diversity, specifically 28 castor genotypes (27 native and 1 modified), a randomized complete block design with three replications was conducted in 2014 and 2015 at the research farm of islamic azad university in damghan, northern iran. during the growth period, the following...

Anonymity(key-privacy) as well as security(data-privacy) are all important features in public-key encryption applications. In this paper two new and general concepts, named “relevant anonymity” and “relevant security”, are defined. Based-upon these concepts some general results on anonymity in public-key encryption are proved, which fall in three categories. The first results are two general re...

To better understand how young Alaska Native (Inupiaq) people are creatively responding to the tensions of growing up in a world markedly different from that of their parents and grandparents, the pilot study examined youthproduced digital stories as representations of their everyday lives, values, and identities. Two hundred and seventy-one youth–produced digital stories were examined and assi...
