Application of Deep Learning and Symmetrized Dot Pattern to Detect Surge Arrester Status
Applied Sciences, 2022 Surge arresters primarily restrain lightning and switch surges in the power system to avoid damaging power equipment. When a surge arrester fails, it leads to huge damage to the power equipment.

Klf10 Regulates the Emergence of Glial Phenotypes During Hypothalamic Development
Journal of Neuroscience Research, Volume 103, Issue 2, February 2025.KLF10, a CREB target, is integral to hypothalamic gliogenesis, ensuring proper glial phenotype emergence and maintenance in adulthood via regulating potential target genes. The Klf10‐deficient mouse provides a model to study the impact of reduced astrocytes and microglia on hypothalamic homeostasis.

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 ...
