In this paper, we study the exchange of messages among a set of processors linked through an interconnection network. We focus on general, non-uniform versions of all-to-all (or complete) exchange problems in asynchronous systems with a linear cost model and messages of arbitrary sizes. We extend previous complexity results to show that the general asynchronous problems are NP-complete. We pres...

microscope of cells fixed in 5 % (v/v) glutaraldehyde after 20min incubation with glycerol mono-oleate. Fused cells were discernible by their size; the number of cells involved in fusion was calculated as a percentage of the total cell number in 10-15 fields for each incubation. Although considerable individual variation occurred, statistically significant increases in cell cholesterol concentr...

We consider the adaptation of random early detection (RED) as a buffer management algorithm for TCP traffic in Internet gateways where different maximum transfer units (MTUs) are used. We studied the two RED variants described in [4] and point out a weakness in both. The first variant where the drop probability is independent from the packet size discriminates connections with smaller MTUs. The...

The effect of cow size on reproduction has become of in, respectively. The hip heights of the small, medium greater concern in recent years as a result of marked and large frame-size bulls used were 53, 55 and 57.5 in, increases in cow size in both purebred and commercial respectively, at 2 yr of age. The bulls were selected from herds and the extremely large effect of fertility on the within t...
