In this paper, we aim to deter urban crime by recommending optimal police patrol strategies against opportunistic criminals in large scale urban problems. While previous work has tried to learn criminals’ behavior from real world data and generate patrol strategies against opportunistic crimes, it cannot scale up to large-scale urban problems. Our first contribution is a game abstraction framew...

background: cryptosporidiumis known as an opportunist disease-causing agent in man in recent decades. it causes diarrhea and intestinal disorders in the immune deficit and immune competent individuals. this study was aimed to investigate the clinical characteristics of hiv/aids patients withcryptosporidiosisinfection. methods: this cross-sectional descriptive study was performed on 53 hiv/aids ...

We present a locational model of banking with two types of private banks, honest and opportunistic, and a state bank that is assumed to be less efficient. Opportunistic banks choose whether to honor their contracts with depositors depending on the probability of contract enforcement. We derive three types of equilibria, which depend on institutional quality: a “low” equilibrium in which private...

Opportunistic networks, in which nodes opportunistically exploit any pair-wise contact to identify next hops towards the destination, are one of the most interesting technologies to support the pervasive networking vision. Opportunistic networks allow content sharing between mobile users without requiring any pre-existing Internet infrastructure, and tolerate partitions, long disconnections, an...

Radio frequency (RF) spectrum is a scarce resource from the perspective of allocation; in the U.S., almost all RF spectrum has already been allocated for specific uses. Much of this allocated spectrum, however, remains idle for large portions of time, and thus RF spectrum is actually a plentiful resource from the perspective of occupancy. Accommodating new wireless services and technologies wil...
