Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations. The primary result, following [1, 17], is the calculation of a stability index whose sign determines a necessary condition for spectral stability. We show that for an ideal gas this index can be ev...

In this paper we give a complete solution to the conjecture of Evans made in 1960 that if n— 1 cells of an nxn matrix are preassigned with no element repeated in any row or column then the remaining n — n+ 1 cells can be filled so as to produce a latin square. We in fact prove the stronger statement that n cells can be preassigned except in certain cases which we specify.

The authors present the first case of regression of cystic lesions on brain MRI in a newborn after therapeutic hypothermia in Poland. Multicystic encephalopathy is the most severe form of hypoxic-ischemic encephalopathy and its regression is described very rarely in the literature. Magnetic resonance imaging is an accepted, optimal method of evaluation of the brain and establishing prognosis in...

Focal cerebral ischemia was produced by occluding the left middle cerebral artery in 769 rats. Permeability of the blood-brain barrier to small or large molecules was evaluated qualitatively using Evans blue or sodium fluorescein and quantitatively using the transfer indexes of iodine-125-labeled bovine serum albumin or [14C]sucrose. Water content was determined using wet and dry weights and so...

introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...
