Postprandial Glucagon Action in the Human Brain
Diabetes, Obesity and Metabolism, EarlyView.ABSTRACT Aims Elevated fasting glucagon is linked to hyperglycemia, but postprandial glucagon effects are less understood. Recent evidence suggests metabolic benefits of rising glucagon after oral glucose intake, potentially impacting brain‐mediated whole‐body metabolism.

High efficiency interleaved bi-directional ZVS DC-DC converter
Journal of Physics: Conference Series, 2013 A high efficiency interleaved bi-directional ZVS DC-DC converter is presented in this paper. This converter can be operated in both buck and boost mode. CoolMOS is used as a power device to achieve low conduction losses and fast turn off. The value of inductance is selected such that the CoolMOS drain-to-source voltage always falls to zero before it ...
