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.

Backup protection method for half-wavelength transmission lines based on inverse-time characteristic

International Journal of Electrical Power & Energy Systems
The advantages of ultra-high voltage (UHV) Half-wavelength AC transmission (HWACT) technology are achieving full-line reactive power self-balancing without the need for reactive power compensation equipment along the line and avoiding the Ferranti effect.

Intersystem fault between MMC‐HVDC and AC systems and its impact on DC/AC protection

IET Generation, Transmission & Distribution, 2022
Flexible DC and AC transmission lines can be arranged across vertically or sharing transmission corridor. Under this condition, the possibility of intersystem fault increases significantly, which endangers the safety of both DC and AC systems.

On the Duality of Probing and Fault Attacks [PDF]

, 2009
In this work we investigate the problem of simultaneous privacy and integrity protection in cryptographic circuits. We consider a white-box scenario with a powerful, yet limited attacker.

Minimising the impact of disturbances in future highly-distributed power systems [PDF]

, 2017
It is expected that future power systems will require radical distributed control approaches to accommodate the significant expansion of renewable energy sources and other flexible grid devices.

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

Adaptive reclosing scheme for flexible HVDC grid with single-pole ground fault based on residual voltage zero-crossing detection

International Journal of Electrical Power & Energy Systems
To avoid the issue of blind reclosing in conventional flexible high voltage direct current (HVDC) grid, investigating an adaptive reclosing scheme capable of identifying fault nature and duration is essential.

A transient and non-unit-based protection technique for DC grids based on the rate-of-change (R-o-C) of the fault induced travelling wave components [PDF]

, 2019
This paper presents a transient and non-unit-based protection scheme for consideration in DC grids of the future. The technique utilises the rate-of-change (R-o-C) of the associated travelling wave components following the occurrence of a fault to ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

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
