 The ratio of independent random variables arises in many applied problems. In this article, the distribution of the ratio X/Y is studied, when X and Y are independent Rice random variables. Ratios of such random variable have extensive applications in the analysis of noises of communication systems. The exact forms of probability density function (PDF), cumulative distribution function (CDF) a...

The paper introduces a new journal impact measure called The Reference Return Ratio (3R). Unlike the traditional Journal Impact Factor (JIF), which is based on calculations of publications and citations, the new measure is based on calculations of bibliographic investments (references) and returns (citations). A comparative study of the two measures shows a strong relationship between the 3R an...

Natural selection acts strongly on the proportional numbers of male and female offspring among the progeny of adults. The equilibrium is often one at which males and females are produced in roughly equal numbers, but under certain ecological and genetic circumstances there may be dramatic population-wide biases, and even in populations with balanced sex ratios, parents are often selected to pro...

Let P be a class of graphs. A P-set in a graph G is a vertex subset X such that G(X) ∈ P . We define the P-stability number of a graph G, αP(G), as the maximum cardinality of a P-set in G. AP-dominating set in a graph is a dominatingP-set. Accordingly, the P-domination number of a graph G, γP(G), is the minimum cardinality of a P-dominating set in G. For each r ≥ 1, we define a graph G to be an...

HSMR is calculated as a ratio of the actual number of deaths to the expected number of deaths among patients in acute care hospitals. An HSMR of 100 indicates there is no difference between the hospital’s mortality rate and the overall average rate. Therefore a rate greater than 100 means the hospital’s mortality rate is higher than the overall average and a rate lower than 100 means the hospit...
