This thesis addresses the topic of secure distributed computation, a general and powerful tool for balancing cooperation and mistrust among independent agents. We study many related models, which diier as to the allowable communication among agents, the ways in which agents may misbehave , and the complexity (cryptographic) assumptions that are made. We(More)
Data collected as part of a multi-year trial examining the efficacies of inactivated and live-attenuated influenza vaccines were used to evaluate the reported occurrence of post-vaccination reactions. Two cohorts were defined: (1) individuals who received the same vaccine over two consecutive years, and (2) individuals who first enrolled in year 2 of the(More)
The prospect of biological attacks is a growing strategic threat. Covert aerosol attacks inside a building are of particular concern. In the summer of 2005, the Center for Biosecurity of the University of Pittsburgh Medical Center convened a Working Group to determine what steps could be taken to reduce the risk of exposure of building occupants after an(More)
Technological change is rapidly moving us into the age of the pocket computer, but in the early 70s we can be content to work with computers no smaller than typewriters. Little computers have long been popular in behavioral laboratories; only recently have they been seriously considered for broader purposes such as instruction or modeling. In this paper we(More)
Lipoic acid is an antioxidant that suppresses and treats a model of multiple sclerosis, experimental autoimmune encephalomyelitis. We now demonstrate that treatment of human PBMC and T cell lines with LA downmodulated CD4 expression in a concentration-dependent manner. LA treatment of Con A stimulated PBMC specifically removed CD4 from the T-cell surface,(More)
Despite the high prevalence of traumatic brain injuries (TBI), there are few rapid and straightforward tests to improve its assessment. To this end, we developed a tablet-based software battery ("BrainCheck") for concussion detection that is well suited to sports, emergency department, and clinical settings. This article is a study of the diagnostic(More)
