This paper describes an original way of dealing with the measuring and modeling of microwave transistor nonlinear behavior. Although generalizations are possible, the method described in this particular paper deals with transistor behavior under a large signal one-tone excitation, with arbitrary impedance terminations for the fundamental and the harmonics. First the mathematical theory of the “...

The unique mechanism of the SCF ubiquitin ligase poses a challenge to drug discovery. A central enzymatic small molecule–binding active site is not evident in this multisubunit protein enzyme, as is the case with kinases or proteases. Instead, the SCF ligase seems to accomplish ubiquitylation through a series of cooperative movements dependent on the protein interfaces between its components an...
