The theoretical case is considered where the total amount of plasma protein is conserved, but the drug is eliminated after its single application. After a single drug application at time t = 0, the total drug concentration is measured at times ti,...,tk and the total drug concentration at time ti is denoted by φi. Our discussion is limited to one protein binding site. The quantity of plasma pro...

This article summarizes the design concepts applied in the development of an advanced Ka-band (34.4 GHz/32 GHz) transponder breadboard for the next generation of space communications systems applications. The selected architecture upgrades the X-band (7.2 GHz/8.4 GHz) deep-space transponder (DST) to provide Ka-band up/Kaand X-band down capability. In addition, it can also be configured to provi...

It has been showed in [4] that any bipartite graph Ka,b, where a, b are even is decomposable into closed trails of prescribed even lengths. In this article we consider the corresponding question for open trails. We prove a necessary and sufficient condition for graphs Ka,b to be decomposable into edge-disjoint open trails of positive lengths (less than ab) whenever these lengths sum up to the s...

Let Ka,b be a complete bipartite multigraph. We show a necessary and sufficient condition for a multigraph Ka,b to be arbitrarily decomposable into open trails. A motivation for us to investigated this problem is a paper of Balister [1].

The purpose of this note is to obtain some congruences modulo a power of a prime p involving the truncated hypergeometric series p−1 � k=1 (x)k(1− x)k (1)k · 1 ka for a = 1 and a = 2. In the last section, the special case x = 1/2 is considered.

The initial expansion of anatomically modern humans (AMH) occurred during a hyperarid event in Africa that occurred 135-75 ka. Large-scale AMH spread in northern Eurasia started during the Middle Weichselian glacial maximum, and proceeded during the subsequent mild interstadial (60-40 ka ago). This expansion which encompassed the polar regions and southern Siberia proceeded at a remarkably rapi...

A family of sets {A k } is called a strong d system if the intersection of any two of its members is the same, i .e ., if A kI n a = A ka n A ka . It is called a weak d system if I A k= rn A k . 1 is the same for any two sets of our family . J systems have recently been studied in several papers . f (n, r) is the smallest integer for which any family of f (n, r) sets A k , I < k < f (n, r) of s...
