Does history repeat itself? Wavelets and the phylodynamics of influenza A.

Unprecedented global surveillance of viruses will result in massive sequence data sets that require new statistical methods. These data sets press the limits of Bayesian phylogenetics as the high-dimensional parameters that comprise a phylogenetic tree increase the already sizable computational burden of these techniques. This burden often results in partitioning the data set, for example, by g...

Garments fire: history repeats itself.

The majority of these workers were also young women, economically disadvantaged, migrants, and, by any definition, vulnerable. Fires have been a persistent prob...

Can sub-Saharan Africa feed itself?

Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue ...
