presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

Negative relationships between allozyme heterozygosity and morphological variance have often been observed and interpreted as evidence for increased developmental stability in heterozygotes. However, inbreeding can also generate such relationships by decreasing heterozygosity at neutral loci and redistributing genetic variance at the same time. I here provide a quantitative genetic model of thi...

The problem of proving generalization bounds for the performance of learning algorithms can be formulated as a problem of bounding the bias and variance of estimators of the expected error. We show how various stability assumptions can be employed for this purpose. We provide a necessary and sufficient stability condition for bounding the bias and variance for the Empirical Risk Minimization al...

Eversince its discovery by Gerletti and Bini (1938), electro-convulsive therapy (E. C. T.) has continued to occupy a central place in the therapeutic armamentarium of psychiatrists. Despite abhorrence from some quarters, it is still being practiced as one of the cheapest and safest, and yet one of the most effective therapeutic techniques in the whole of medical science (Kalinowsky, 1975; Royal...

This paper examines conditions for the uniqueness of an equilibrium price distribution in stochastic macroeconomic models with rational expectations. A model is developed in which many price distributions, each with a finite variance, satisfy the equilibrium requirements of rationality. Hence, the condition that the variance of the equilibrium price distribution be finite, or equivalently, that...
