Due to our limited knowledge about silicon carbide metal–oxide–semiconductor fieldeffect transistors (SiC MOSFETs), the theoretical analysis and change regularity in terms of the effects of temperature on their switching characteristics have not been fully characterized and understood. An analysis of variation in voltage (dVDS/dt) for SiC MOSFET during turn-on and turn-off has been performed th...

Temperature coefficients have been measured by 2D NMR methods for the amide and C alpha H proton chemical shifts in two globular proteins, bovine pancreatic trypsin inhibitor and hen egg-white lysozyme. The temperature-dependent changes in chemical shift are generally linear up to about 15 degrees below the global denaturation temperature, and the derived coefficients span a range of roughly -1...

The main purpose of this study was to examine the effect of chalk on the friction coefficient between climber's fingers and two different rock types (sandstone and limestone). The secondary purpose was to investigate the effects of humidity and temperature on the friction coefficient and on the influence of chalk. Eleven experienced climbers took part in this study and 42 test sessions were per...

Using a linear optical diffraction technique, we have systematically investigated the defect effects on quantum surface diffusion of hydrogen on Pt(111) surfaces. The quantum tunneling effect was clearly observed for hydrogen diffusion at low temperatures as manifested by a leveling off of the diffusion coefficient on flat surfaces. The strong influence of surface defects on the quantum diffusi...

We consider the Nernst effect in the normal state of the underdoped cuprate superconductors, where recent quantum oscillation experiments have indicated the existence of Fermi surface pockets and quasiparticle ambipolarity in the excitation spectrum. Using an ambipolar d-density-wave model for the pseudogap, we predict a peak in the Nernst coefficient with decreasing temperature below the pseud...
