Most work in algorithmic game theory assumes that players ignore costs incurred by their fellow players. In this paper, we consider superimposing a social network over a game, where players are concerned with minimizing not only their own costs, but also the costs of their neighbors in the network. We aim to understand how properties of the underlying game(More)
This paper evaluates the use of radiofrequency (RF) magnetic field gradient echoes to provide contrast in magnetic resonance (MR) images of model tumors. Decay of RF gradient echoes as a function of evolution time was measured and sensitivity of the decay to changes in blood pressure was evaluated. Previous investigators have demonstrated that static field(More)
Haloperidol levels were measured by radioreceptor assay in 12 schizophrenic patients during gradual dosage reduction (at 10-day) intervals) from 60 to 0 mg/day. Serum levels were highly correlated with the oral dose in each patient, but poorly correlated across patients. Clinical deterioration appeared only 10-20 days after total cessation of the oral drug,(More)
Experiments were performed to determine whether T2* and resonance frequency weighted MR images are sensitive to effects of hyperoxia on model tumors. Hyperoxia can increase tumor oxygen tension and thus affect T2* and/or the average resonance frequency within each image voxel due to the paramagnetism of oxygen itself or through modulation of the oxidation(More)
Social networks are the substrate upon which we make and evaluate many of our daily decisions: our costs and benefits depend on whether---or how many of, or which of---our friends are willing to go to that restaurant, choose that cellular provider, already own that gaming platform. Much of the research on the ``diffusion of innovation,'' for example, takes(More)
INTRODUCTION In conventional (kinetic) U.S. warfare, there exists a standard methodology for identifying and assessing collateral damage (i.e. accidental damage to civilian targets). Indeed, the U.S. Department of Defense (DoD) relies on a governing document that defines the policy regarding unlawful military targets (no-strike targets), and methods for(More)
Despite some evidence that neuroleptic medication is overused or misused in long-term care facilities for the elderly, there has been virtually no attention paid to the pattern of use of antidepressants in these facilities. All patients in long-term care in a geriatric hospital and a home for the aged who were receiving antidepressants were identified;(More)
