#### [Seminar on Bioinformatics] The discussion on the Out of Africa hypothesis, OOAH and PPA (Progressive Phylogenetic Analysis), that identified the African human populations as paraphyletic

Abstract：The Out of Africa hypothesis, OOAH, was challenged recently in an extended mtDNA analysis, PPA (Progressive Phylogenetic Analysis), that identified the African human populations as paraphyletic, a finding that contradicted the common OOAH understanding that Hss had originated in Africa and invaded Eurasia from there. The results were consistent with the molecular Out of Eurasia hypoth...

#### Generalized Paley Graphs, Finite Field Hypergeometric Functions and Modular Forms

AbstractIn 1955, Greenwood and Gleason proved that the two-color diagonal Ramsey number R(4,4) equals 18. Key to their proof was constructing a self-complementary graph of order 17 which does not contain a complete subgraph of order four. This graph is one in the family of graphs now known as Paley graphs. In the 1980s, Evans, Pulham and Sheehan provided a simple closed formula for the number o...
