A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...

This paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. A modified objective function associated with a new start-up cost term is introduced in this paper. The proposed method is used to solve generating scheduling problem satisfying SRR, minimum up and down time as well as ramp rate constraints. Two case studies are conducted to imp...

keratoderma is a group of disorders characterized by abnormal thickening of skin. acquired palmar keratoderma has many underlying causes. the association of thyroid disease and palmar keratoderma rarely reported. hypothyroidism, although very rare association, must be suspected in patients with acquired ppk, particularly when it occurs in setting of systemic symptoms or predisposing conditions....

conclusions the current study indicated that h. pylori infection occurs at a higher rate in patients with down syndrome and mental retardation. this may provide more reasons to control the transmission of h. pylori among them. results the differences between the groups were compared by t-test and x2 test. seropositivity for h. pylori was significantly higher in patients with down syndrome and m...

we report three cases of asymptomatic celiac disease identified in children with down syndrome after being screened at around twenty-four months of age.  these cases raise the question as to what age is screening for celiac disease indicated in a child with down syndrome and no symptoms.

Acute stress is associated with beneficial as well as detrimental effects on cognition in different individuals. However, it is not yet known how stress can have such opposing effects. Stroop-like tasks typically show this dissociation: stress diminishes speed, but improves accuracy. We investigated accuracy and speed during a stroop-like task of 120 healthy male subjects after an experimental ...

Performance prediction of checkpointing systems in the presence of failures is a well-studied research area. This paper makes three small contributions to this research area. First, we show how to apply the concept of availability from reliability theory as a useful metric for checkpointing systems. Second, we study the average availability of uniprocessor checkpointing systems, using the libck...
