The standard model of particle physics contains parameters--such as particle masses--whose origins are still unknown and which cannot be predicted, but whose values are constrained through their interactions. In particular, the masses of the top quark (M(t)) and W boson (M(W)) constrain the mass of the long-hypothesized, but thus far not observed,...

We present the results of a search for the production of new particles decaying into two jets in pbarp collisions at sqrt{s} = 1.8 TeV, using the DZero 1992-1995 data set corresponding to 109 pb^-1.

The role of intrinsic pouch motility after ileal pouch-anal anastomosis (IPAA) during defecation is still speculative. IPAA was performed in 12 dogs. Defecation mechanisms were evaluated by motility recordings during spontaneous defecation and during expulsion of an endoluminal balloon and by radiography with sequential sector-related gray scale an...

The use of anticholinergic drugs has provided a useful therapeutic approach to reduce stool frequency in patients with proctocolectomy and ileal pouch-anal anastomosis (IPAA). Botulinum type-A (BTA) toxin has been shown to specifically block acetylcholine release in the intestinal wall. Therefore this study investigated the effect of BTA on small i...

The reasons why the choice of the right power supply is critical in keeping communications systems online are discussed. A common track adopted by system designers is to use a standard power supply and boost heat removal by changing the mechanical design. The positioning of the power supply within the enclosure can help to minimize the ambient oper...

Sphincter preservation is a goal in the treatment of rectal cancer and should be considered in all patients with intact analsphincter.
