Computational and experimental mapping of the allosteric network of two manganese ABC transporters
Protein Science, Volume 34, Issue 2, February 2025.Abstract Transition metals (e.g., Fe2/3+, Zn2+, Mn2+) are essential enzymatic cofactors in all organisms. Their environmental scarcity led to the evolution of high‐affinity uptake systems. Our research focuses on two bacterial manganese ABC importers, Streptococcus pneumoniae PsaBC and Bacillus anthracis MntBC, both critical for virulence.

Mechanism and suppression of breaking overvoltage of DC circuit breakers
High Voltage, Volume 10, Issue 1, Page 32-46, February 2025.Abstract The occurrence of breaking overvoltage in a DC circuit breaker (DCCB) poses a potential threat to the safe operation of a DC grid. Based on the structure of the ±10 kV three‐terminal DC distribution network, this paper sets up the medium‐voltage DCCB and formulates a fault protection strategy.

High Voltage, Volume 10, Issue 1, Page 78-87, February 2025.Abstract Metal oxide varistors (MOVs) are extensively employed in DC circuit breakers (DCCBs) to suppress overvoltage, dissipate energy and build up voltage after interruption. Despite their widespread use, the performance of MOVs under short‐time, double energy absorption conditions is not well understood, posing a challenge to their application in ...
