Under the influence of novel coronavirus, China's cross-border e-commerce has rapidly developed. At same time, entities transaction have brought a series credit risks in order to maximize their profits, which hindered sound development e-commerce. On basis combing relevant research literature, this paper analyzes current statusand risk e-commerce, and proposes reduce promotes healthy sustainabl...

After healing of experimental myocardial infarction in cat hearts, endocardial cells demonstrate persistent regional electrical changes. These include long action potential duration in surviving cells over the infarct scar, and short action potential duration and low membrane potential in border zone cells between the scar and normal tissue. We studied the basis for these electrophysiological c...

trong economic interaction exists between communities on both sides of the U.S.–Mexico border. Just count the number of Mexican license plates on autos parked in U.S. malls, or note the many service and goods suppliers in U.S. border cities that support manufacturing in Mexico. Casual observation reveals patterns of local specialization, where work is often divided between the two cities on a s...

We set out in this study to analyse the impact of institutional distance on the cross-border interorganizational system (IOS) adoption and assimilation. This study begins with an introduction of two crucial constructs, i.e. institutional distance and interdependence, and then distinguishes IOS adoption from IOS assimilations. These static portraits are the basis by which we explore the relation...

Southeast Asia (the Thailand-Cambodia border) has been considered the primal epicenter for most antimalarial drug resistance; however, numerous molecular epidemiological studies have successively reported multiple independent origins of sulfadoxine-pyrimethamine (SP) resistance-associated Plasmodium falciparum dhfr (pfdhfr) and pfdhps alleles in other areas. To better understand the origin and ...

We have determined the effect of the side chain on the uptake of sterols from micellar solutions by isolated rat jejunal villus cells, brush border membranes, and erythrocytes. From an equimolar mixture of 7-dehydrosterols, the uptake decreased with an increasing number of carbon atoms at C24 of the sterol side chain in a manner identical to that observed for the parent-delta 5-sterols. The bru...

Disruption of the renal proximal tubule (PT) brush border is a prominent early event during ischemic injury to the kidney. The molecular basis for this event is unknown. Within the brush border, ezrin may normally link the cytoskeleton to the cell plasma membrane. Anoxia causes ezrin to dissociate from the cytoskeleton and also causes many cell proteins to become dephosphorylated in renal PTs. ...

Many countries, European and worldwide, have increasingly issued during the last decade electronically readable identity documents to their citizens, for different purposes and applications. However, a major characteristic of all these systems is that they are basically available in a national context. For example, European citizens that move freely through the Member-States face the problem th...

In this tutorial paper, we first discuss the motivation of doing symbolic-numeric computation, with the aim of developing efficient and certified polynomial solvers. We give a quick overview of fundamental algebraic properties, used to recover the roots of a polynomial system, when we know the multiplicative structure of its quotient algebra. Then, we describe the border basis method, justifyin...

This paper examines the effective representation of the punctual Hilbert scheme. We give new equations, which are simpler than Bayer and Iarrobino-Kanev equations. These new Plücker-like equations define the Hilbert scheme as a subscheme of a single Grassmannian and are of degree two in the Plücker coordinates. This explicit complete set of defining equations for Hilb(P) are deduced from the co...
