A Novel Decentralized Approach for Leveraging EVs in DC Microgrid Load Shedding

, 2022
The load shedding would be the last option for maintaining the integrity of isolated microgrids in the event of an insufficient generation. In this paper, a novel decentralized adaptive timer-based approach is proposed to facilitate electric vehicles ...

An adaptive under-frequency optimal control strategy for power system combined pumped storage and under-frequency load shedding.

PLoS ONE, 2021
With the construction and development of ultra-high voltage (UHV) power grids, large-scale, long-distance power transmission has become common. A failure of the connecting line between the sending-end power grid and the receiving-end power grid will ...

Enhanced inflammation and suppressed adaptive immunity in COVID-19 with prolonged RNA shedding

Cell Discovery, 2022
Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity of SARS-CoV-2 infection. Here, we found that patients with long viral RNA course (LC) exhibited prolonged high-level IgG antibodies and higher regulatory T (Treg ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
