We show that the modified log-Sobolev constant for a natural Markov chain which converges to an $r$-homogeneous strongly log-concave distribution is at least $1/r$. Applications include sharp mixing time bound bases-exchange walk matroids, and concentration Lipschitz functions over these distributions.

In this work we report on a transaction log analysis of the Dutch Folktale Database, an online repository of extensively annotated folktales ranging from old fairy tales to recent urban legends, written in (old) Dutch, Frisian and a variety of Dutch dialects. We observed that users have a preference for subgenres within folktales such as traditional legends and urban legends and prefer stories ...

Parker (1) has shown that the results of infectivity measurements with vaccinia virus may be interpreted as a Poisson distribution of single infective particles among aliquots of the virus obtained by dilution. Thus, if it may be assumed that there exists a quanti ty of virus invariably necessary and invariably sufficient to produce a lesion in the skin of the rabbit, the behavior on dilution r...

Turkey has initiated a number of projects to improve the quality of education and to provide students with knowledge and skills needed for the job market through the integration of information and communication technology (ICT) into education during the last twenty-five years. This paper is an overview of those initiatives of ICT in education in Turkey. It is argued that more attention is neede...

Recently, Pawlik et al. have shown that triangle-free intersection graphs of line segments in the plane can have arbitrarily large chromatic number. Specifically, they construct triangle-free segment intersection graphs with chromatic number Θ(log log n). Essentially the same construction produces Θ(log log n)-chromatic triangle-free intersection graphs of a variety of other geometric shapes—th...

This paper examines the effect of the default interface language on the usage of a bilingual digital library. In 2005 the default interface language of a bilingual digital library was alternated on a monthly basis between Māori and English. A comprehensive transaction log analysis over this period reveals that not only did usage in a particular language increase when the default interface langu...
