This paper discusses a possible approach to ranking geographic regions that can influence multiple infrastructures. Once ranked, decision makers can determine whether these regions are critical locations based on their susceptibility to terrorist acts. We identify these locations by calculating a value for a geographic region which represents the combined(More)
Gene trees will often differ from the true species history, the species tree, as a result of processes such as incomplete lineage sorting. New methods such as Bayesian Estimation of the Species Tree (BEST) use the multispecies coalescent to model lineage sorting, and directly infer the species tree from multilocus DNA sequence data. The Sulidae (Aves:(More)
Functional magnetic resonance imaging (fMRI) activation in white matter is controversial. Given that many of the studies that report fMRI activation in white matter used high field MRI systems, we investigated the field strength dependence of sensitivity to white matter fMRI activation. In addition, we evaluated the temporal signal to noise ratio (tSNR) of(More)
