For a large class of stationary probability measures on A/sup N/, where A is a finite alphabet, we compute the specific Renyi entropy of order /spl alpha/ and the specific guesswork moments of order /spl beta/ > -1. We show that the specific guesswork moment of order /spl beta/ equals the specific Renyi entropy of order /spl alpha/ = 1 / (1 + /spl beta/)(More)
The hospital records of all patients presenting to a large urban trauma center emergency department with facial fractures from 1980 through 1984 were reviewed retrospectively. There were 788 patients in the study group, averaging 1.8 fractures per patient for a total of 1,423 facial fractures. The study population had 638 (80.9%) males and 150 (19.1%)(More)
Full-thickness cranial (membranous) and split-thickness iliac crest (endochondral) onlay bone grafts were placed subperiosteally without fixation onto the snout (membranous) and tibia (endochondral) in 30 rats. The animals had been divided into three equal groups in which the bone grafts had been demineralized, autoclaved, or used fresh. Recipient sites(More)
With quality and public reporting of increasing importance, benchmarks are anticipated to grow in relevance. We studied cholecystectomy in a practice in an urban tertiary care hospital. A total of 1083 cholecystectomies were performed in 2008 and 2009. Laparoscopic cholecystectomy was performed in 97.8 per cent of patients with a 2.2 per cent conversion(More)
(this covers the basic methods along with chapters on probabilistic risk analysis, decision trees, cost accounting, and activity-based costing; it has a supplement "Electronic Spreadsheets for Engineering Economy Applications", and it has a web site for support) Others: (a very practical text with chapters on each of the evaluation methodologies; the focus(More)
Of 457 patients with facial fractures admitted by the plastic surgery service from 1986 to 1988 at Wayne State University, there were seven displaced orbital roof fractures in five patients. All presented with supraorbital rim fractures, inferior dystopia, limitation of supraduction, upper eyelid ptosis, and diplopia. Proptosis was present in four orbits in(More)
In utero cleft lip repairs were done by full-thickness approximation of the cleft edges by 11-0 sutures in the A/J mouse on day 17 of gestation after Dilantin was administered on day 10. On day 20, a cesarean section was performed, the repair inspected, and the lip sectioned for histologic study. One-thousand one-hundred and thirty-nine mice were bred, and(More)
The purpose of this article is twofold: (1) to investigate the histomorphology of cartilaginous proliferation using three different otoplasty techniques and (2) to determine whether recurrence is related either to the method of otoplasty or the duration of suture fixation. Eighteen 6-week-old New Zealand white rabbits were divided into three equal groups.(More)
