Direct determinations of the nucleon and pion $\sigma$ terms at nearly physical quark masses

, 2016
We present a high statistics study of the pion and nucleon light and strange quark sigma terms using $N_f=2$ dynamical non-perturbatively improved clover fermions with a range of pion masses down to $m_\pi\sim 150$ MeV and several volumes, $Lm_\pi=3.4 ...

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.

Research on compound current control strategy based on LCL type active power filter

Gong-kuang zidonghua, 2017
In view of contradiction between high steady state accuracy and fast dynamic response of traditional current control strategy, a novel compound current control strategy based on LCL type active power filter was proposed.

Strong convergence and convergence rates of approximating solutions for algebraic Riccati equations in Hilbert spaces [PDF]

The linear quadratic optimal control problem on infinite time interval for linear time-invariant systems defined on Hilbert spaces is considered. The optimal control is given by a feedback form in terms of solution pi to the associated algebraic Riccati ...

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

Brushless DC Motor Control System for Active Myoelectric Prostheses

Visión Electrónica, 2023
A prosthesis is an artificial substitute for a missing part of the body that makes it possible to recover some degree of function of the lost limb. Prosthetics are classified as passive and active.

Rolling quantum dice with a superconducting qubit

, 2014
One of the key challenges in quantum information is coherently manipulating the quantum state. However, it is an outstanding question whether control can be realized with low error.

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.
