Valley splitting in finite barrier quantum wells" (2008). Birck and NCN Publications. Paper 148. The valley splitting ͑VS͒ in a silicon quantum well is calculated as a function of barrier height with both the multiband sp 3 d 5 s ‫ء‬ model and a simple two-band model. Both models show a strong dependence of the VS on barrier height. For example, in both models some quantum wells exhibit a sharp m...

The relative rates of erosion by rivers and glaciers, and the topographic effects of these two different styles of erosion, remain outstanding problems in geomorphology. We use a quantitative description of local fluvial landscapes to estimate how glaciated landscapes might look now had glaciers not developed. This indicates the landscape modification attributable to glacial erosion. We present...

The pathological changes of erythrocytes were detected at the nanometer scale, which was important for revealing the onset of diseases, early diagnosis, and effective therapies. Diseases may disturb the morphology and function of erythrocytes at molecular scale. There were dramatic surface deformations in topography of erythrocytes from a patient with elliptocytosis complicating idiopathic thro...

during this survey 29 sites have been recognized totally. settlement patterns determined base of environmental characteristics such as altitude, ground slope, source of water, petrology and geology, vegetations, land use and specifications of sites including width, chronology, regional distribution and density and all of them have been divided by using geographic information systems (gis) and c...

Complex traits often involve interactions between different genetic loci. This can lead to sign epistasis, whereby mutations that are individually deleterious or neutral combine to confer a fitness benefit. In order to acquire the beneficial genotype, an asexual population must cross a fitness valley or plateau by first acquiring the deleterious or neutral intermediates. Here, we present a comp...

The thermally driven wind over mountainous terrains challenges the estimation of CO2 exchange between forests and the atmosphere when using the eddy covariance technique. In this study, the wind regimes were investigated in a temperate deciduous forested valley at the Maoershan site, Northeast China. The wind direction above the canopy was preferentially up-valley in the daytime and down-valley...
