Technically, the Loop’s construction began in 1978. But it wasn’t called the Loop then. If you’re unfamiliar, the Loop is a 131-mile trail that spans Tucson, South Tucson, Oro Valley and Marana.

Here we use cryogenic electron microscopy to determine the structure of TbAQP2 from Trypanosoma brucei, bound to either the substrate glycerol or to the sleeping sickness drugs, pentamidine or ...

This paper compares the system oscillation characteristics under strong and weak grid conditions with PMSG using open-loop control and current closed-loop control. By employing dynamic frequency ...

A control strategy for the active power decoupling in a single-phase full-bridge-based bidirectional dc–ac converter is proposed in this work. An ac-side auxiliary-circuit three-leg topology is used ...
