Electrical properties

This study aims to contribute to the development of a GaN/Ga2O3 diode that can be utilized in high-power device applications. The simulated device is calibrated against experimental GaN and Ga2O3 diodes, considering the effect of thickness of GaN layer and its doping concentration on the performance of GaN/Ga2O3 diodes. The band structures of devices are investigated to revial which factors that affect the properties of GaN/Ga2O3 diode.

K-Ras is a small G-protein, localized mainly at the inner leaflet of the plasma membrane. The membrane targeting signal of this protein consists of a polybasic C-terminal sequence of six contiguous lysines and a farnesyl-ated cysteine. Results from biophysical studies in model systems suggest that hydrophobic and electrostatic interactions are responsible for the membrane binding properties of K-Ras.

Diffuse noxious inhibitory controls (DNIC) can be produced by different types of conditioning stimuli, but the analgesic properties and underlying mechanisms remain unclear. The aim of this study was to differentiate the induction of DNIC analgesia between noxious electrical and inflammatory conditioning stimuli. Methods: First, rats subjected to either a supramaximal electrical stimulation or an injection of high-dose formalin in the hind limb were identified to have pain responses with behavioral evidence and spinal Fos-immunoreactive profiles. Second, suppression of tail-flick...
