We study extreme Nash equilibria in the context of a selfish routing game. Specifically, we assume a collection of n users, each employing a mixed strategy, which is a probability distribution over m parallel identical links, to control the routing of its own assigned traffic. In a Nash equilibrium, each user selfishly routes its traffic on those links that minimize its expected latency cost. T...

The key problem in testing for racial profiling in traffic stops is estimating the risk set, or " benchmark, " against which to compare the race distribution of stopped drivers. To date, the two most common approaches have been to employ Census-based residential population data or to conduct traffic surveys in which observers tally the race distribution of drivers at a certain location. It is w...

Introduction: The elderly represent a significant proportion of the populace and their mortality index is of public health significance. With dearth of vital registration, in-hospital based studies remains a desirable alternative. This study hopes to determine the epidemiologic pattern of elderly mortality with respect to sex, age, date and cause of death.  Methods: This is descriptive retrosp...
