In this paper we consider the diffusive search for a bounded target $\Omega \in \R^d$ with its boundary $\partial \Omega$ totally absorbing. We assume that is surrounded by semipermeable interface given closed surface \calM$ \subset \calM\subset \R^d$. That is, surrounds and thus partially screens process. also position of diffusing particle (searcher) randomly resets to initial $\x_0$ accordin...

]T is well known that the cornea will swell if excised and placed in an aqueous solution, and the attention of many investigators has been turned to the reason for its unswollen state in the normal eye. It is generally accepted that the explanation lies in the properties of the limiting membranes of the cornea and various theories have been propounded as to the mechanism of their action. Leber ...

background several studies have been carried out to evaluate the effects of dialysis on o2 saturation. while the dialysis procedure may lead to hypoxia under different circumstances, there are few studies available on the effects of membrane type on o2 saturation in these patients. objectives this study was to appraise the effects of high and low flux membrane on pulse oxymetery in dialysis pat...

From semipermeable membrane devices (SPMDs) placed in five Mississippi Delta streams in 1996 and 1997, the persistent organic pollutants (POPs) aldrin, chlordane, DCPA, DDT, dieldrin, endrin, heptachlor, mirex, nonachlor, and toxaphene were detected. In addition, the insecticides chlorpyriphos, endosulfan, and hexachlorocyclohexanes were detected. Two low-solubility herbicides not detected comm...

It has been much debated how the Drosophila immune system can recognize bacterial peptidoglycan that is often hidden. We show that bacteria separated from Drosophila S2 cells by a semipermeable membrane can upregulate the Imd pathway. Supernatants from exponentially growing but not from stationary-phase bacterial cultures induce antimicrobial peptides. It is also made likely that the shed elici...
