We present an asymptotic study on the phase diagram of two-dimensional nematic liquid crystal polymer monolayers with the Onsager intermolcular potential. In contrast to the case of MaierSaupe interaction potential where there is only one nematic branch, our analysis reveals that there are infinite many nematic branches in the case of the Onsager interaction potential. An asymptotic expression ...

abstract turbidity current is one of the most important factors that effect the sediments distribution and also their transportation and release from reservoir. in this study, effects of these currents on sedimentation process in sefidroud dam were simulated by tcm model in 30 years period. comparison between the case of turbidity currents that reach to the dam wall and release from the reservo...

changes of hydrodynamic parameters in microchannel branches affect the suspended biological samples in blood. to prevent denaturation and hemolysis, we have numerically investigated the effect of divergence angle on shear rate and velocity at branch entrance (discharge rate), under electroosmotic flow. in such flow, hydrodynamic properties are also affected by zeta potential at the microchannel...

This paper shows that context switching is not a sig-niicant factor to be considered when performing general branch prediction studies. Branch prediction allows for speculative execution by increasing available instruction level parallelism (ILP) and hiding the time required to resolve branch conditions. Accurate simulation of branch prediction is important because branch prediction strongly in...

The occurrence of bundle branch block in acute myocardial infarction is important because it indicates that infarction may be extensive and may result in cardiac failure or death; however, the presence of bundle branch block is also important because it indicates seriously jeopardized AV conduction which could result in sudden extremely slow heart rates or asystolic arrest. The aim of the study...

Measurements were made of parent and branch vessel diameters and of the included angles of branch-points from postmortem human coronary arteriograms to determine the usefulness of theoretical equations predicting the relationships between parent and branch vessel caliber and between arterial caliber and branch-angle. The formulas were based on the concept that blood vessel size and arrangement ...

The rotation of horizontal branch stars places important constraints on angular momentum evolution in evolved stars and therefore rotational mixing on the giant branch. Prompted by new observations of rotation rates of horizontal branch stars, we calculate simple models for the angular momentum evolution of a globular cluster giant star from the base of the giant branch to the star’s appearance...

In this paper, using generalized {polya} urn models we find the expected value of the size of a branch in recursive $k$-ary trees. We also find the expectation of the number of nodes of a given outdegree in a branch of such trees.

The branch site of group II introns is typically a bulged adenosine near the 3'-end of intron domain 6. The branch site is chosen with extraordinarily high fidelity, even when the adenosine is mutated to other bases or if the typically bulged adenosine is paired. Given these facts, it has been difficult to discern the mechanism by which the proper branch site is chosen. In order to dissect the ...
