Fleet-sizing and service availability for a vehicle rental system via closed queueing networks
In this paper, we address the problem of determining the optimal fleet size for vehicle rental company and derive analytical results for its relationship to vehicle availability at each rental station in the company's network of locations. Expand
Asymptotic analysis of closed queueing networks and its implications to achievable service levels
Closed queueing networks have been widely used to model many types of service networks. Expand
Heightened CD40 ligand gene expression in peripheral CD4+ T cells from patients with kidney allograft rejection.
BACKGROUND CD40 ligand (CD40L) gene expression is increased in rejecting allograft biopsies. We, therefore, tested the possibility that CD40L gene expression is heightened in peripheral CD4+ T cells… Expand
HLA-identity--long-term renal graft survival, acute vascular, chronic vascular, and acute interstitial rejection.
The object is analysis of the impact of acute and chronic rejection on long-term function in HLA-identical renal transplants performed from 1967 to 1995 by the Saskatchewan Renal Transplant Unit.… Expand

Lack of early acute rejection does not predict safe tapering of immunosuppression.
In an effort to reduce long-term complications of immunosuppressive medications, some investigators have devised protocols of reduced dosage [Kupin et al. 1988, Kelly et al. 1989, Reinsmoen et al.… Expand

Outpatient upper gastrointestinal endoscopy: large, prospective study of the morbidity and mortality rate at a single endoscopy unit in England
Background: There are few prospective studies that look at the standards of the practice of esophago‐gastroduodenoscopy (EGD) and its associated morbidity.
3359 Morbidity rate of diagnostic upper gastrointestinal endoscopy at a single endoscopy unit and patient's preference for sedation.
Clinical and endoscopic data were collected from the endoscopy and nursing records. 30 days after the EGD, 383 patients (93.6%) were contactable (telephone - 359; post - 24). RESULTS: Median age of… Expand
