This paper presents results from the first rational model of eye movement control in reading to make predictions for the full range of the eye movement record. The model identifies the text through Bayesian inference and makes eye movement decisions to maximize the efficiency of text identification, going beyond leading approaches which select model parameters to maximize the fit to human data....

The desire to infer the evolutionary history of a group of species should be more viable now that a considerable amount of multilocus molecular data is available. However, the current molecular phylogenetic paradigm still reconstructs gene trees to represent the species tree. Further, commonly used methods of combining data, such as the concatenation method, are known to be inconsistent in some...

Neotropical vine snakes (Oxybelis) have a wide distribution range from southern United States to southeastern Brazil. Notably, the widespread brown snake O. aeneus was recently split into eight species, but major geographical areas such as South American Pacific lowlands remained unsampled. In this paper, we present largest molecular phylogeny of Oxybelis date using six mitochondrial and nuclea...

The 174-kb virulence plasmid pMUM001 in Mycobacterium ulcerans epidemic strain Agy99 harbors three very large and homologous genes that encode giant polyketide synthases (PKS) responsible for the synthesis of the lipid toxin mycolactone. Deeper investigation of M. ulcerans Agy99 resulted in identification of two types of spontaneous deletion variants of pMUM001 within a population of cells that...

If variation in azole resistance is due to inherent differences in strains of Candida albicans, as a predominantly clonal organism, then correlation between multilocus genotypes and drug resistance would be expected. A sample of 81 clinical isolates from patients infected with human immunodeficiency virus in Toronto, Canada, plus 3 reference isolates were genotyped at 16 loci, distributed on al...
