Much of the recent research and development in the area of high-speed TCP is focused on the steady state behavior of TCP flows. However, our experience with the first research only transatlantic 2.5 Gbps Lambda link clearly demonstrates the need to focus on the initial stages of TCP. The work we present here examines the behavior of TCP flows at microscopic level over high-bandwidth long delay ...

Of 52 cases with 56 affected renal units having symptoms and signs suggestive of Ureteropelvic Junction Obstruction (UPJO) evaluated by conventional (F + 15) diuretic renography where frusemide is given 15 minutes post-injection of radiopharmaceutical m99TC.DTPA.F + 15, twelve (21%) showed a good clearance (group A), 16 (28%) showed partial (group B) and 28 (50%) a poor clearance pattern (group...

medication errors (mes) are the most common error in icus. in fact, 78% of all serious errors in icus are due to mes. therefore, detecting mes has vital significance. the goal of this study was to investigate the frequency, type and consequences of different types of errors including prescribing, transcribing and administration errors in an icu of a large teaching hospital. disguised direct obs...

Acid-base equilibria/disequilibria were evaluated in vivo in post-branchial arterial blood and pre-branchial venous blood of freshwater rainbow trout (Oncorhynchus mykiss). This was accomplished using arterial and venous extracorporeal circuits in conjunction with a stopped-flow apparatus. After the abrupt stoppage of circulating post-branchial blood within the stopped-flow apparatus, pH increa...

Endothelin is a potent vasoconstrictor peptide produced by endothelial cells, but its role in physiology and disease is uncertain. We investigated the influence of the endothelin-A-selective receptor antagonist PD 147953 and the nonselective endothelin receptor antagonist PD 145065 on the effects of endothelin-1 and endothelin-3 in the skin microcirculation of healthy volunteers, using laser Do...

We report on the design and fabrication of porous silicon based rugate filters. We have achieved narrow line-width, high reflectivity optical filters made entirely from silicon by continuously varying of the refractive index of Si and apodizing the index profile of the structure. 2005 Elsevier B.V.

DEVELOPMENT OF A CHEMICALLY REACTING FLOW SOLVER ON THE GRAPHIC PROCESSING UNITS

To characterize the total retinal blood flow determined by laser speckle flowgraphy (LSFG) of healthy subjects.This prospective cross-sectional study was conducted at the Nagoya University Hospital. One hundred fifteen right eyes of 115 healthy subjects (mean age: 39.4 ± 16.1 years) were studied. The total blood flow in the retinal arteries and veins around the optic nerve head was measured sep...

BACKGROUND White cell filtration of red cell concentrates is often performed at the bedside, in the ward, with the filter inserted in the blood administration line. The aim of this study was to evaluate the efficiency of this filtration method and compare it to filtration in the blood bank. STUDY DESIGN AND METHODS One-day-old, buffy coat-reduced, hard-packed red cell concentrates in saline-a...

In neurophysiological experiments examining the selectivity of MSTd neurons to visual motion components of optic flow stimuli in monkeys, Duffy and Wurtz (1991) reported cells with double-component (plano-radial and plano-circular) and triple-component (plano-radial-circular) selectivities, while Graziano et al (1994) reported neurons selective to a continuum of optic flow stimuli including spi...
