BACKGROUND AND PURPOSE To investigate experimental mechanisms of reversible cerebral dysfunction, we produced transient focal cerebral ischemia in five baboons by unilateral perfusion of internal carotid territories with platelet microemboli generated endogenously. METHODS Platelet microemboli were formed by incorporating segments of Dacron vascular graft for 1 hour as unilateral carotid arte...
background: in survival studies when the event times are dependent, performing of the analysis by using of methods based on independent assumption, leads to biased. in this paper, using copula function and considering the dependence structure between the event times, a parametric joint distribution has made fitting to the events, and the effective factors on each of these events would be determ...
Evolutionary change is a product of selection. Selection operates on the phenotype, and its consequences are manifest in representation of the genotype in successive generations. Of particular interest to both evolutionary and behavioral biologists is the newly emerging field of epigenetics and behavior. Two broad categories of epigenetic modifications must be distinguished. Context-dependent e...

We present here by direct argument the classical Clopper-Pearson (1934) “exact” confidence bounds and corresponding intervals for the parameter p of the binomial distribution. The same arguments can be applied to derive confidence bounds and intervals for the negative binomial parameter p, for the Poisson parameter λ, for the ratio of two Poisson parameters, ρ = λ1/λ2, and for the parameter D o...
Set-point theory posits that individuals react to the experience of major life events, but quickly adapt back to pre-event baseline levels of subjective well-being in the years following the event. A large, nationally representative panel study of Swiss households was used to examine set-point theory by investigating the extent of adaptation following the experience of marriage, childbirth, wid...
In this work we present a novel word lattice filtering algorithm which removes redundancy from lattices. We use the filtering algorithm to analyze lattices obtained from dynamic network and transducer-based LVCSR decoders from several sites regarding size, coverage, and redundancy. We show that our filtering algorithm reduces the size of lattices by 30 to 90% without degrading the oracle word e...
