Nectar is a “network backplane” for use in heterogeneous multicomputers. The initial system consists of a star-shaped fiber-optic network with an aggregate bandwidth of 1.6 gigabits/second and a switching latency of 700 nanoseconds. The system can be scaled up by connecting hundreds of these networks together. The Nectar architecture provides a(More)
Multicomputers built around a general network are now a viable alternative to multicomputersbased on a system-specific interconnect because of architectural improvements in two areas. First, the host-network interface overhead can be minimized by reducing copy operations and host interrupts. Second, the network can provide high bandwidth and low latency by(More)
The recent unfortunate rabies transmissions through solid organ transplants of an infected donor in Germany required the initiation of a vaccination program to protect health care workers (HCWs) with close contact to rabies-infected patients. A systematic follow-up of adverse effects was initiated. Rabies postexposure prophylaxis (PEP) was started in 269(More)
BACKGROUND This article describes multiple transmissions of rabies via transplanted solid organ from a single infected donor. The empirical Milwaukee treatment regimen was used in the recipients. METHODS Symptomatic patients were treated by deep sedation (ketamine, midazolam, and phenobarbital), ribavirin, interferon, and active and passive vaccination.(More)
Given a map in which each position is associated with a travcrsability cost, the path planning problem is to find a minimum-cost path from a source position to every other position in the map. The paper proposes a dynamic programming algorithm to solve the problem, and analyzes the exact number of operations that the algorithm takes. The algorithm accesses(More)
