The present inventors have discovered that histidinol-phosphatase is essential for fungal pathogenicity. Specifically, the inhibition of histidinol-phosphatase gene expression in fungi results in small, non-sporulating lesions and reduced pathogenicity. Thus, histidinol-phosphatase can be used as a .....

A new technology for measuring liquid crystal (LC) cell properties is invented. Optical properties and characteristics of LC cells including cell gap, twist angle and rubbing directions of a liquid crystal cell can therefore be measured. They are important parameters for the operation of a liquid .....

Many electronic applications require multiple regulated supply voltages to cater for needs from the different function modules inside. A new single-inductor multiple-output (SIMO) switching converter is designed to operate in pseudo-continuous conduction mode (PCCM) with free wheel switching, and ca.....

There are many applications for the Liquid crystal displays (LCD) that are bistable under zero voltage bias conditions. For examples, bistable cholesteric LCD; bistable ferroelectric LCD; bistable twisted nematic LCD where the two stable twist states differ by 360 degrees in twist angle; bistable tw.....
