In reading through the various preprints, I was struck by the fact that many were concerned with specific computer implementations of one kind or another. Unfortunately, there seems to be little discussion of the program-ing from the programmer's viewpoint. This is under standable in a congress of computational linguistics but, I feel, somewhat regrettable. Especially nce the reports of what ha...

Usually propagation-based constraint solvers construct a constraint network as a conjunction of constraints. They provide propagators for each form of constraint c. In order to increase expressiveness, systems also usually provide propagators for reified forms of constraints. A reified constraint b ↔ c associates a truth value b with a constraint c. With reified propagators, systems can express...

In the first half we show an interesting relation between coherent states and the Bell states in the case of spin 1/2, which was suggested by Fivel. In the latter half we treat generalized coherent states and try to generalize this relation to get several generalized Bell states. Our method is based on a geometry and our task may give a hint to open a deep relation between a coherence and an en...

Four patients who developed deep infection of six hips, on average three and a half years after total replacement by McKee-Farrar prostheses, are described. In each case there was strong evidence that the source of the infection was a distant focus.

Background: The role of wound drainage after total knee arthroplasty is still considered controversial as althoughclosed drainage systems have been believed to be effective in decreasing the post-operative complications, they couldalso facilitate the bleeding and increase the rate of transfusion and infection. We have conducted the current study tocompare the outcomes superficial subcutaneous, ...
