Fifth list of new double stars

Dengue ranks fifth in the list of neglected tropical diseases

The growing burden of dengue in endemic countries and outbreaks in previously unaffected countries stress the need to assess the economic impact of this disease. This paper synthesizes existing studies to calculate the economic burden of dengue illness in the Americas from a societal perspective. Major data sources include national case reporting data from 2000 to 2007, prospective cost of illn...

Graph Choosability and Double List Colorability

In this paper, we give a sufficient condition for graph choosability, based on Combinatorial Nullstellensatz and a specific property, called “double list colorability”, which means that there is a list assignment for which there are exactly two admissible colorings.

Anti-Ramsey numbers of spanning double stars

In this paper we shall prove and sharpen a conjecture of A. Bialostocki on anti-Ramsey colorings of the complete graph Kn. Assume the edges of a Kn are colored by t colors. The basic question is how many colors ensure that Kn has a spanning subtree of diameter at most d in which each edge has a different color. The surprising fact is that the answers are the same for every d ≥ 3. Moreover, we c...
