One of the main reasons for failure in cancer chemotherapy is the selective growth of drug resistant cells during treatment. Agents that are non-toxic and can reverse this drug resistance is of great value to cancer chemotherapy. Rhizoma Alismatis, its extracts and fractions or chemicals isolated fr.....

Existing methods for multi-string applications require many windings in the isolation transformers because each converter output needs one winding. This invention, a dimmable LED driver, can reduce the number of windings. It also possesses a two-secondary-winding structure to generate several source.....

This invention relates to a self-adaptive dual-loop phased source (SDPS) array equipped with a phase detector array (PDA), which is inserted between the output and input of the phased source array to form a dual-phase locked loop (PLL) structure. One loop is for frequency locking and the other loop .....

Synchronous rectification is applied in switched mode circuits for reducing conduction losses in low-voltage and high-current applications. The self-driven AC-DC synchronous rectification technique developed by CityU can be used to fabricate an AC-DC synchronous rectifier that behaves like a diode b.....
