Finite-diierence approximations preserving the cosymmetry property for two-dimensional ltration convection problem are presented. Cosymmetry preserving discretizations connrm the predicted behavior of the family of equilibria and degeneration of the family is observed when an inappropriate approximation was used. 1 Planar Darcy convection problem and cosymmetry In recent years several discretiz...

Zero till is commonly advocated as a preferred cropping system to conventional, multicultivation practices. Zero till is particularly attractive on clay soils, to minimise compaction and induce natural structure formation through shrink±swell cycles. Increases in soil water storage and increased numbers of (bene®cial) soil fauna with zero till have been reported, relative to traditional tillage...

Dear Editor, Eosinophilic gastroenteritis (EG) is a rare infl ammatory disorder of the gastrointestinal tract of unknown aetiology. It is characterised by eosinophilic infi ltration of the bowel wall, peripheral eosinophilia and various gastrointestinal manifestations. We report CT appearances in a rare case of EG with duodenal obstruction, peripheral eosinophilia and eosinophilic ascites, whic...

In a neutrophil-dependent arthritis elicited by injections of a mixture of anti – type II collagen mAbs followed by LPS, mice lacking the tyrosine-based inhibitory receptor leukocyte Iglike receptor B4 (LILRB4) have an exacerbated clinical response characterized morphologically by greater synovial thickening with neutrophil infi ltration and depletion of articular cartilage matrix with erosions...

Sir, In their article in Nephrology Dialysis Transplantation w1x, discussing the pathophysiology of acute renal failure in the nephrotic syndrome, Koomans et al. (p. 223) mention that obliteration of epithelial slit pores, as visualized by electron microscopy, is not correlated with the reduction in glomer-ular ®ltration rate (GFR) in humans. However, in a previous

This paper studies the stability of the solution of backward stochastic diierential equations under small perturbations of the underlying ltration. The problem is interesting from the mathematical point of view, but also for its possible applications in Finance Theory, as it might represent a model to describe approximated information or inside information for an economic agent.

In order to realize the quantum group in a global way, the Hall algebra of a root category (which is a orbit category of the derived category of a hereditary algebra) is constructed. The PBW-basis, ltration structure and integral form are investigated. Their degeneration at v = 1 actually provide a realization of the universal enveloping algebra of semisimple Lie algebras.
