Sample size calculation formulas for testing equality, noninferiority, superiority, and equivalence based on odds ratio were derived under both parallel and one-arm crossover designs. An example concerning the study of odds ratio between a test compound (treatment) and a standard therapy (control) for prevention of relapse in subjects with schizophrenia and schizoaffective disorder is presented...

We report the first observation of B → ηX transitions with high momentum η mesons. We observe 39.0 ± 11.6 B decay events with 2.0 < pη′ < 2.7 GeV/c, the high momentum region where background from b → c processes is suppressed. We discuss the physical interpretation of the signal, including the possibility that it is due to b → sg transitions. Given that interpretation, we find B(B → ηXs) = (6.2...

In this paper, we propose a new physical synthesis methodology, PDL, which relaxes the timing constraints to obtain best optimality in terms of layout quality and timing quality. It provides a common database for delay calculation, logic optimization, placement, and routing tools so that they can work and interact closely. We present results on industrial circuits showing the efficacy of this m...

This paper discusses a statistical effect of performance optimization to uncertainty in circuit delay. Performance optimization has an effect of balancing the delay of each path in a circuit, i.e. the delay of long paths are shortened and the delay of short paths are lengthened. In these path-balanced circuits, the uncertainty in circuit delay, which are caused by delay calculation error, manuf...

In this article, HIV incidence density is estimated from prevalence data and then used together with reported cases of AIDS to estimate incubation-time distribution. We used the deconvolution technique and the maximum-likelihood method to estimate parameters. The effect of truncation in hazard was also examined. The mean and standard deviation obtained with the Weibull assumption were 12.9 and ...
