Land surface heterogeneity and tornado occurrence: an analysis of Tornado Alley and Dixie Alley

Peak tornado activity is occurring earlier in the heart of Tornado Alley

Tornado frequency may increase as the factors that contribute to severe convection are altered by a changing climate. Attributing changes in tornado frequency to observed global climate change is complicated because observational effort has increased over time, but studies of the seasonal distribution of tornado activity may avoid sampling biases. We demonstrate that peak tornado activity has s...

Neurogenesis and depression: breakthrough or blind alley?

Pieces of evidence are emerging in support of the startling idea that the birth of new neurones in the adult brain in some way underlies major depression.

The Taming of Two Alley CATs

Round robin tournaments are used in a wide variety of competition settings and especially in recreational sports leagues. The outcomes of such tournaments can be modelled by an orientation of the edges of a complete graph, where each vertex corresponds to a unique competitor. A score sequence is an nondecreasing sequence of the out-degrees of such a graph. In this paper we analyze two previousl...
