Lattice tests are quality measures for assessing the intrinsic structure of pseudorandom number generators. Recently a new lattice test has been introduced by Niederreiter and Winterhof. In this paper, we present a general inequality that is satisfied by any periodic sequence. Then, we analyze the behavior of the linear congruential generators on elliptic curves (abbr. EC-LCG) under this new la...

This paper proposes a modal logic reconstruction of temporal reasoning about partially ordered events in a logic programming framework. It considers two variants of Kowalski and Sergot's Event Calculus (EC): the Skeptical EC (SKEC) and the Credulous EC (CREC). In the presence of partially ordered sequences of events, SKEC and CREC derive the maximal validity intervals over which the relevant pr...

Endothelial cells (EC) metabolize L-arginine mainly by arginase, which exists as two distinct isoforms, arginase I and II. To understand the roles of arginase isoforms in EC arginine metabolism, bovine coronary venular EC were stably transfected with the Escherichia coli lacZ gene (lacZ-EC, control), rat arginase I cDNA (AI-EC), or mouse arginase II cDNA (AII-EC). Western blots and enzymatic as...

OBJECTIVE Extracellular superoxide dismutase (EC-SOD) is a secreted antioxidant enzyme that binds to the outer plasma membrane and extracellular matrix through its heparin-binding domain (HBD). Carriers of a common genetic variant of EC-SOD (EC-SOD(R213G), within the HBD) have higher plasma concentration of EC-SOD and increased risk for vascular disease. In the present study, we used confocal f...

The present study aimed to evaluate the potential of improving feeding value Egyptian clover (EC), ryegrass (R), triticale (T), barley (B), and oats (O) monoculture, or mixed with (EC+R), (EC+O), barely (EC+B), (EC+T) at 75:25% seeding rate, respectively, during two successive winter seasons 2018/19 2019/20. Harvesting plots was carried out 5 cm stubble height after 60, 100, 140 days from sowin...

Vascular functions are affected by wall shear stresses (WSS) applied on the endothelial cells (EC), as well as by the interactions of the EC with the adjacent smooth muscle cells (SMC). The present study was designed to investigate the effects of WSS on the endothelial interactions with its surroundings. For this purpose we developed and constructed two co-culture models of EC and SMC, and comp...
