Abstract:
An ignition system providing power and duration controlled ignition spark, comprises a spark controller, first switching energy accumulator, storage capacitor, and second switching energy accumulator with an ignition coil. The ignition system utilizes dual means of switching energy accumulation, internal energy transfer, and three means of energy release to the ignition spark, working in all possible combinations managed by means of the spark controller depending on engine operating conditions, and provides continuous bipolar ignition spark. Spark profile is regulated by means of control signals (2) and (3) based on their frequency, duty cycle, interrelation, and running time.
Abstract:
This disclosure relates generally to compounds and compositions comprising one or more diphenylethylene, diphenylethylyne, and azobenzene analogs. These compounds are useful for treating diseases associated with NF-kB and p53 activity, such as cancer and inflammatory disease.
Abstract:
The determination and use of three dimensional structures of receptor protein tyrosine kinases and/or their ligands are described. One particular group of such structures includes three dimensional structures of the extracellular domain of RPTKs. The three dimensional structures of RPTKs can faciliate the design and identification of modulators of RPTK function. Other such structures can include of RPTK ligands, such as stem cell factor or a fragment thereof. Modulators of RPTK function can be used to treat diseases that are mediated by inappropriate RPTK activity.
