‎For a given measure space $(X,{mathscr B},mu)$ we construct all measure spaces $(Y,{mathscr C},lambda)$ in which $(X,{mathscr B},mu)$ is embeddable‎. ‎The construction is modeled on the ultrafilter construction of the Stone--v{C}ech compactification of a completely regular topological space‎. ‎Under certain conditions the construction simplifies‎. ‎Examples are given when this simplification o...

in this research, performance of portfolios formed by use of grid strategy based on new variables (aggressive, indifference and defensive stocks) presented by rahnamaye roodposhti (1388), and traditional ones (growth, growth-value and value stocks), calculated with sharpe and treynor performance measures and tested by an active portfolio management approach to identify the portfolios by perform...

The study of oxidative phosphorylation’ by the classical techniques of fractionation and isolation of the purified reactants has not been feasible because of the lability of the reaction systems. Consequently indirect approaches to the problem have been adopted. This paper reports results from one such approach; namely, study by the use of Pa2 and 01* of enzymic exchange reactions of phosphate ...

We present algorithms for five interdistance enumeration problems that take as input a set S of n points in IRd (for a fixed but arbitrary dimension d) and as output enumerate pairs of points in S satisfying various conditions. We present: an O(n log n + k) time and O(n) space algorithm that takes as additional input a distance δ and outputs all k pairs of points in S separated by a distance of...
