This invention is about three new measuring methods to determine the twist angle and retardation value of any twisted nematic liquid crystal cell. Twist angle of the liquid crystal alignment and the retardation value are important design parameters in determining the optical performance of liquid c.....

III-nitride compound semiconductors have the merits of wide band gap, high breakdown field, and large thermal conductivity, which results in well designed AlGaN/GaN heterojunction field-effect transistors. This transistor is capable of high temperature operation, suitable for high temperature integr.....

Voltage-controlled oscillators (VCO) are one of the most essential building blocks in phase-locked loops and frequency synthesizers, which are required in all data communication and telecommunication systems for generating highly accurate timing reference sources. However, existing VCOs need a suppl.....

Antidepressants such as Prozac, Paxil and Zoloft, are characterized by an ability to selectively block reuptake of serotonin (5-HT). Selective NE-reuptake inhibitor antidepressants such as Tomoxetine and Vivalan have also been developed. Effexor and Serzone have been termed SNRI antidepressants beca.....
