The alleviation effect on the Schottky barrier height (SBH) (ΦB) using ultrathin titanium dioxide and hafnium dielectrics in a single layer bilayer stack was demonstrated. ΦB Pt/n-Si contact reduced from 0.53 to −0.058, 0.3, −0.12 eV 3 nm TiO2, 1 HfO2, high-k/high-k insertion, respectively. A maximum of 122% reduction obtained dielectric which is highest ever reported so far diode. This achieve...

Artery-to-muscle (A-M) onset time for five neuromuscular blocking agents was studied in 50 female patients under light endotracheal anaesthesia. Circulation to the right arm was occluded by a tourniquet and released 1 min after the injection i.v. into the left arm of a myoneural blocking drug. Muscle twitches were recorded in the right hand after stimulation of the ulnar nerve (1 Hz). After rel...

The purpose of this study was to determine the effects of two different strength-power training models on sprint performance. Forty-eight soldiers of the Brazilian brigade of special operations with at least one year of army training experience were divided into a control group (CG: n = 15, age: 20.2 ± 0.7 years, body height: 1.74 ± 0.06 m, and body mass: 66.7 ± 9.8 kg), a traditional training ...

Gap phase dynamics are the dominant mode of forest turnover in tropical forests. However, gap processes are infrequently studied at the landscape scale. Airborne lidar data offer detailed information on three-dimensional forest structure, providing a means to characterize fine-scale (1 m) processes in tropical forests over large areas. Lidar-based estimates of forest structure (top down) differ...

We investigate the expressive power of first-order quantifications in the context of monadic second-order logic over pictures. We show that k+1 set quantifier alternations allow to define a picture language that cannot be defined using k set quantifier alternations preceded by arbitrarily many first-order quantifier alternations. The approach uses, for a given picture language L and an integer ...

OBJECTIVE To determine the six-minute walking distance (6MWD) for healthy Pakistanis, identify factors affecting 6MWD, compare published equations with the local data and derive an equation. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Two medical institutes of Karachi, from January to May 2011. METHODOLOGY Subjects between 15 and 65 years were prospectively enrolled af...

Changes in tropical-forest structure and aboveground biomass (AGB) contribute directly to atmospheric changes in CO2, which, in turn, bear on global climate. This paper demonstrates the capability of radar-interferometric phase-height time series at X-band (wavelength = 3 cm) to monitor changes in vertical structure and AGB, with sub-hectare and monthly spatial and temporal resolution, respecti...

Hyperphagia is a frequent symptom in patients with Prader-Willi Syndrome (PWS) and results in marked obesity with the risk of metabolic and cardiovascular complications. Previously, we reported that our special diet for PWS patients is effective in the long run, if started early at about 2 years of age. Our objective in this study was to investigate if our special diet is also effective in PWS ...

Colorectal adenomas may be either protruding type or superficial type lesions. To delineate the clinicopathological characteristics of the latter, 153 superficial type adenomas (including the surrounding mucosa) obtained by endoscopic resection were studied morphologically. Superficial type adenomas were defined as flat or flat depressed adenomas with a height of </=3 mm; histologically, the tu...
