Enhanced (Na+, K+)-activated ATPase activity after indirect electric stimulation of rat skeletal muscle in vivo
Abstract A significant increase in sarcolemma bound ATPase activity was obtained after indirect electric stimulation of leg muscles in rats. The enzyme activity was assayed on isolated sarcolemma, and the unstimulated leg served as control. Membrane located 5′-nucleotidase was unaffected by the muscle activity.
Abstract We study the effect of trapping/detrapping of a single-electron in interface states in the channel of n-type MOSFETs with decanano dimensions using 3D atomistic simulation techniques. In order to highlight the basic dependencies, the simulations are carried out initially assuming continuous doping charge, and discrete localized charge only for the trapped electron. The dependence of the random telegraph signal (RTS) amplitudes on the device dimensions and on the position of the trapped charge in the channel are studied in detail. Later, in full-scale, atomistic simulations assuming discrete charge for both randomly placed dopants and the trapped electron, we highlight the importance of current percolation and of traps with strategic position where the trapped electron blocks a dominant current path.
