Whey-derived peptides interactions with ACE by molecular docking as a potential predictive tool of natural ACE inhibitors [PDF]

, 2020
Several milk/whey derived peptides possess high in vitro angiotensin I-converting enzyme (ACE) inhibitory activity. However, in some cases, poor correlation between the in vitro ACE inhibitory activity and the in vivo antihypertensive activity has been ...

A review on flicker-free ac-dc LED drivers for single-phase and three-phase ac power grids [PDF]

, 2019
Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density.

Less is More: Real-time Failure Localization in Power Systems [PDF]

, 2019
Cascading failures in power systems exhibit non-local propagation patterns which make the analysis and mitigation of failures difficult. In this work, we propose a distributed control framework inspired by the recently proposed concepts of unified ...

Searching for a Connection Between Matroid Theory and String Theory [PDF]

, 2002
We make a number of observations about matter-ghost string phase, which may eventually lead to a formal connection between matroid theory and string theory.

Dual Active Bridge Converter

, 2021
De mange bruksområdene til den isolerte toveis DC-DC-omformeren har fanget oppmerksomheten til industrien, og den mest lovende topologien av disse er Dual Active Bridge(DAB) omformeren. Denne omformertopologien krever videre forskning på dens drift, for å kunne utvikle ytelsen på DAB-omformeren videre.
