Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Inverse time overcurrent protection for low-frequency wind farm transmission lines based on transient current components

International Journal of Electrical Power & Energy Systems
Low-Frequency Transmission Systems (LFTS) integrate the benefits of both high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) transmission technologies. This combination makes LFTS a significant innovation for transmitting large

Backup-Protection Scheme for Multi-Terminal HVDC System Based on Wavelet-Packet-Energy Entropy

IEEE Access, 2019
DC fault protection is a major issue in multiterminal high-voltage DC current transmission systems. Most studies have focused on primary protection, which considers a different theory.

Power supply arm protection scheme of high-speed railway based on wide-area current differential

Railway Engineering Science, 2023
When fault occurs on cross-coupling autotransformer (AT) power supply traction network, the up-line and down-line feeder circuit breakers in the traction substation trip at the same time without selectivity, which leads to an extended power failure ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Multi-terminal flexible DC grid circuit breaker withstands multi-lightning strike analysis

Scientific Reports
Lightning represents the primary threat to power grids, with approximately 80% of natural occurrences being multi-lightning strikes, which have been extensively studied and confirmed to pose even more severe hazards.

Fault location in the observation matrix of collection lines for grid-connected wind power supported by grid-forming energy storage

International Journal of Electrical Power & Energy Systems
Aiming at the problem that the accuracy of fault location in the collection line supported by energy storage for wind power grid connection is easily affected by the number of measurement points and the access of power electronic equipment, a fault ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Active arc suppression method for voltage-current injection coordination in unbalanced distribution networks

International Journal of Electrical Power & Energy Systems
The challenge of extinguishing arc grounding faults persists as cable-based distribution networks become more prevalent. Current single injection arc extinction methods struggle to effectively mitigate arc grounding faults in unbalanced distribution ...
