Cyclin-dependent kinases (Cdks) are key regulatory enzymes in the eukaryotic cell cycle. The activation of a Cdk depends on its association with its specific cyclin partner. The activity of these enzymes is further regulated by an intricate system of protein-protein interactions and phosphorylation......

Thin film transistors (TFTs) fabricated on polycrystalline silicon (polysilicon) have gained much attention in flat panel displays such as active matrix liquid crystal displays (LCDs) and in static random access memory (SRAM) units. In comparison with thick film devices TFT devices made with a thin .....

Flue gases produced in combustion processes, such as coal-fired power plants, automobiles, smelters, etc., contains huge amount of nitrogen and sulfur oxides, carbon monoxide and particulates. They contribute significantly to atmospheric pollution and some of them are stringently controlled by legis.....

Low-dropout regulator is a commonly used component in the power management integrated circuits for portable electronic devices. Conventionally, the stability of the regulator was achieved by frequency compensation such as dominant-pole compensation and pole-zero cancellation. However, this limits th.....

In recent years the demand for small cellular handsets has grown substantially and the need for still smaller handsets continues to increase. Planer inverted-F antenna (PIFA) designs have received attention since they are compact. Although smaller sizes PIFA are needed, the design of compact antenna.....
