We revisit the problem of interval estimation of a binomial proportion. The erratic behavior of the coverage probability of the standard Wald confidence interval has previously been remarked on in the literature (Blyth and Still, Agresti and Coull, Santner and others). We begin by showing that the chaotic coverage properties of the Wald interval are far more persistent than is appreciated. Furt...
The proportion of mutants in a growing culture of organisms will depend upon (a) the rate at which the wild cells produce them (with or without growth), (b) the back mutation rate, and (c) the growth rates of the wild and mutant cells. If the mutation rate without growth and the back mutation rate are neglected, the growth of a mutant is expressed by See PDF for Equation and the ratio of the mu...
Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...
It remains unknown whether current disease-targeting therapy can histologically reverse obstructive pulmonary vasculopathy and how the timing of the therapy influences the antiremodeling effects of the compound. We test the hypothesis that a novel endothelin receptor antagonist macitentan reverses the early and/or late stages of occlusive pulmonary vascular disease (PVD) in rats. Rats with pulm...
hybrid-density functional theory (b3lyp/def2-tzvpp) based method and nbointerpretation were used to investigate the conformational behavior of 1,2-dihalodisilanes[halo=f (1), cl (2), br (3), i (4)]. the b3lyp/def2-tzvpp results showed that the anticonformations of compounds 1-4 are more stable than their corresponding gaucheconformations. the stability of the anti conformation compared to the g...
