BACKGROUND Our purpose was to compare the Revised Trauma Score (RTS) with the new Field Triage Score (FTS) for prediction of mortality (MORT) and of need for massive transfusion (MASS, >or=10 units of packed cells or whole blood) in casualties arriving at combat support hospitals in Iraq. METHODS Six hundred ninety-two cases were reviewed; 536 had complete data and were included. Total Glasgo...

Analyses of global climate policy as a sequential decision under uncertainty have been severely restricted by dimensionality and computational burdens. Therefore, they have limited the number of decision stages, discrete actions, or number and type of uncertainties considered. In particular, other formulations have difficulty modeling endogenous or decision-dependent uncertainties, in which the...
