Study on the Charge Transfer Criterion for the Pole-to-Ground Fault in DC Distribution Networks

IEEE Access, 2019
After a pole-to-ground fault occurs in the DC distribution network using low current grounding, the fault pole voltage drops while that of the non-fault pole rises, which is harmful to equipment insulation and operational safety.

Agnuside Stabilizes the Complex I Assembly Factor NDUFAF6 to Reinforce Mitochondrial Efficiency and Thermogenic Responsiveness

Advanced Science, EarlyView.
ABSTRACT Brown and beige adipocytes dissipate energy as heat, yet effective strategies to enhance their mitochondrial efficiency remain limited. Here, we identify Agnuside (AGN) as a selective stabilizer of the complex I assembly factor NDUFAF6. AGN directly binds cytosolic NDUFAF6, suppresses its ubiquitination, prolongs its half‐life, and facilitates
