We consider the tradeoffs between packet delay guarantees and per-timeslot computation complexity in an packet switch operating under the crossbar constraint. It is well known that scheduling packets every timeslot according to a Maximum Weight Matching (MWM) achieves 100% throughput. This algorithm ensures average packet delay is within O(n) timeslots(More)
Treatment of common variable immunodeficiency disorders (CVID) is based on replacement therapy using intravenous (i.v.) or subcutaneous (s.c.) immunoglobulin (Ig)G. Interindividual variation of IgG dose is common. A total of 380 CVID patients on stable IgG replacement from two prospective cohorts were analysed. An 'efficiency' index was defined as the ratio(More)
