Service differentiation is one of the key issues in the current Internet. In this paper, we focus on a recent proposal for proportional loss rate differentiation which employs a single FIFO queue, an AQM algorithm for computing the packet drop probability, and a counter-based packet dropping routine for achieving the intended proportional loss rate differentiation among classes. It is first sho...

PURPOSE Little is known about students who seriously consider dropping out of medical school. The authors assessed the severity of thoughts of dropping out and explored the relationship of such thoughts with burnout and other indicators of distress. METHOD The authors surveyed medical students attending five medical schools in 2006 and 2007 (prospective cohort) and included two additional med...

DESCRIPTION A 71-year-old man with history of asthma, non-insulin-dependent diabetes mellitus, and chronic obstructive pulmonary disease was treated for squamous cell carcinoma of the oral cavity. He underwent a partial mandibular resection with plate reconstruction followed by subsequent radiation therapy. A neck dissection was performed during NEXT

Many teachers allow students to drop the lowest score from a sequence of quizzes, tests, or homework assignments. When the number of grades is large, some teachers will even allow students to drop several of their lowest scores. A computer gradebook program would need to implement an algorithm to provide this feature (see one of many examples of computer gradebook software, for example, [4]). A...

Fast Congestion Notification (FN) one of the proactive queue management mechanisms that practices congestion avoidance to help avoid the beginning of congestion by marking/dropping packets before the router’s queue gets full; and exercises congestion control, when congestion avoidance fails, by increasing the rate of packet marking/dropping. Upon arrival of each packet, FN uses the instantaneou...

in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...
