This paper revisits the problem of locating a signal-emitting source from time-difference-of-arrival (TDOA) measurements under non-line-of-sight (NLOS) propagation. Many currently fashionable methods for NLOS mitigation in TDOA-based localization tend to solve their optimization problems by means convex relaxation and, thus, are computationally inefficient. Besides, previous studies show that m...
CONTEXT Delayed access to medical care in patients with acute myocardial infarction (AMI) is common and increases myocardial damage and mortality. OBJECTIVE To evaluate a community intervention to reduce patient delay from symptom onset to hospital presentation and increase emergency medical service (EMS) use. DESIGN AND SETTING The Rapid Early Action for Coronary Treatment Trial, a randomi...
BACKGROUND AND PURPOSE An effective stroke code system that can expedite rapid thrombolytic treatment requires effective notification/communication and an organized team approach. We developed a stroke code program based on the computerized physician order entry (CPOE) system and investigated whether implementation of this CPOE-based program is useful for reducing the time from arrival at emerg...
Aerosol particles can strongly affect both air quality and the radiation budget of the atmosphere. Above Beijing, the capital city of China, large amounts of aerosols within the atmospheric column have caused the deterioration of local air quality and have influenced radiative forcings at both the top and the bottom of the atmosphere (BOA and TOA). Observations of aerosol radiative forcing and ...
At rst sight real time and asynchronous message passing like in SDL and ROOM seem to be incompatible Indeed these languages fail to model real time constraints accurately In this paper we show how to reconcile real time with asynchronous message passing by using an assumption which is supported by every mailing system throughout the world namely that messages are time stamped with their sending...
