UFBoot2: Improving the Ultrafast Bootstrap Approximation
The standard bootstrap (SBS), despite being computationally intensive, is widely used in maximum likelihood phylogenetic analyses. We recently proposed the ultrafast bootstrap a...
Genetic Distance between Populations
A measure of genetic distance (D) based on the identity of genes between populations is formulated. It is defined as D = -logeI, where I is the normalized identity of genes betw...
A Mathematical Theory of Communication
Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Comm...
Fast model-based estimation of ancestry in unrelated individuals
Population stratification has long been recognized as a confounding factor in genetic association studies. Estimated ancestries, derived from multi-locus genotype data, can be u...

Chord
A fundamental problem that confronts peer-to-peer applications is to efficiently locate the node that stores a particular data item. This paper presents Chord, a distributed loo...
Agency costs of free cash flow, corporate finance, and takeovers
Corporate managers are the agents of shareholders; a relationship fraught with conflicting interests. Agency theory, the analysis of such conflicts, is now a major part of the e...
