The quantum circuit model is the most widely used model of quantum computation. It provides both a framework for formulating quantum algorithms and an architecture for the physical construction of quantum computers. However, several other models of quantum computation exist which provide useful alternative frameworks for both discovering new quantum(More)
This paper describes the instruction cache unit (ICU) of the IBM POWER2'" processor, with emphasis on improvements over the original POWER ICU design. The POWER2 ICU incorporates a new compare-branch scheme that minimizes processing time penalties, a second branch processor, increased branch look-ahead capability, and doubled instruction-fetch and(More)
BACKGROUND HDL size and composition vary among individuals and may be associated with cardiovascular disease and diabetes. We investigated the theoretical relationship between HDL size and composition using an updated version of the spherical model of lipoprotein structure proposed by Shen et al. (Proc Natl Acad Sci U S A 1977;74:837-41.) and compared its(More)
The approach of Bayesian mixed effects modeling is an appropriate method for estimating both population-specific as well as subject-specific times to steady state. In addition to pure estimation, the approach allows to determine the time until a certain fraction of individuals of a population has reached steady state with a pre-specified certainty. In this(More)
The clinical behavior of renal cell carcinoma (RCC) cannot be pre dicted by histological and other markers. In this study, comparative genomic hybridization was used to evaluate whether the number of genomic aberrations has prognostic significance in 41 nonmetastatic clear cell RCC extending beyond the renal capsule. Losses were most prevalent at 3p (56%)(More)
A radioimmunoassay has been developed for detecting human schistosomiasis with a highly purified Schistosoma mansoni egg antigen labelled with iodine-125. The antigen, major serologic antigen 1 (M.S.A.1), has striking immunochemical and species specificity and appears to be the principal antigen responsible for the granulomatous response to S. mansoni eggs.(More)
