Webster, Daniel R., and Darby L. Patrick. Beating rate of isolated neonatal cardiomyocytes is regulated by the stable microtubule subset. Am J Physiol Heart Circ Physiol 278: H1653–H1661, 2000.—We investigated the roles of microtubule (MT) dynamics (growth and shrinkage), the stable, nongrowing MT subset, the posttranslationally detyrosinated MT subset, and artificially elevated tubulin levels ...

The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...

in the transformation semigroup (x, s) we introduce the height of a closed nonempty invariant subset of x, define the transformed dimension of nonempty subset s of x and obtain some results and relations.

background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

In this article, we are concerned by existence and uniqueness of a fixed point for the sum two operators A B, defined on closed convex subset an ordered Banach space, where order is induced normal minihedral cone. such structure, absolute value function generated provide ability to introduce new versions concepts lipschitzian expansive mappings. Therefore prove that if B contractive, then + has...

Let $R$ be an infinite ring. Here we prove that if $0_R$ belongs to ${x_1x_2cdots x_n ;|; x_1,x_2,dots,x_nin X}$ for every infinite subset $X$ of $R$, then $R$ satisfies the polynomial identity $x^n=0$. Also we prove that if $0_R$ belongs to ${x_1x_2cdots x_n-x_{n+1} ;|; x_1,x_2,dots,x_n,x_{n+1}in X}$ for every infinite subset $X$ of $R$, then $x^n=x$ for all $xin R$.

Abstract A flag domain in ℝ 3 {\mathbb{R}^{3}} is a subset of the form { stretchy="false">( x , y t stretchy="false">) : < A ...

let x1;x2;...;xn have a jointly multivariate exchangeable normal distribution. in this work we investigate another proof of the independence of x and s2 using order statistics. we also assume that (xi ; yi); i =1; 2;...; n; jointly distributed in bivariate normal and establish the independence of the mean and the variance of concomitants of order statistics.
