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.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

High Voltage, 2021 A previously unidentified duality between buck and boost configured dc‐ac modular multilevel converters (MMCs) is firstly revealed. Armed with this insight, a new dual‐active‐bridge (DAB)‐MMC is proposed for high‐voltage dc (HVDC)‐to‐medium‐voltage dc ...

Smart Transformer-Based Single Phase-To-Neutral Fault Management [PDF]
IEEE Transactions on Power Delivery, 2019 The smart transformer (ST), with its high control capability, offers new features for optimizing the management of the distribution grid. The ST, by controlling the voltage in each phase independently, is able to manage the operations during grid faults, in particular in the single-phase ones.

Discussion of Auxiliary Power Source Open-Phase Protection in Nuclear Power Plant
南方能源建设[Objective] The auxiliary power source in nuclear power plant operates at no-load normally, the protection cannot alarm when it occurs single phase open, but this open-phase condition will threaten the nuclear safety seriously, it should assemble special

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.

Evaluation of DC-AC Single-Phase Solid-State Transformers [PDF]
IEEE Latin America Transactions, 2019 This work presents an evaluation of three topologies of DC-AC single-phase solid state transformers, for applications in electric microgrids. The main features of these topologies are galvanic isolation, capability to control the power flow bidirectionally, soft switching and unit power factor under open loop control. The principle of operation of each

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
