Advanced Science, EarlyView.PA accumulates after hypoxic‐ischemic injury and stabilizes the E3 ligase TRIM59 in OPCs. Stabilized TRIM59 enhances ubiquitination and degradation of Olig2, blocking differentiation and causing hypomyelination in PWMI. Modulating PA synthesis restores Olig2 levels, improves myelination, and ameliorates behavioral deficits, defining a metabolically ...

Smearing of Coulomb Blockade by Resonant Tunneling
, 2000 We study the Coulomb blockade in a grain coupled to a lead via a resonant impurity level. We show that the strong energy dependence of the transmission coefficient through the impurity level can have a dramatic effect on the quantization of the grain ...

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening
Advanced Science, EarlyView.This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...

Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis
Advanced Science, EarlyView.A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

Advanced Science, EarlyView.Hydrogen incorporation in palladium is directly probed using in situ ambient‐pressure hard X‐ray photoelectron spectroscopy under realistic, application‐relevant conditions. Correlated structural, spectroscopic, and theoretical analysis reveals how hydrogen loading modifies structure, electronic structure, and metal‐hydrogen bonding, resolving long ...

Advanced Science, EarlyView.The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

Assessment the quality of removal the smear layer using by rotary tool with zero taper
Эндодонтия Today, 2020 Smear layer is created by rotary and hand instrumentation. This layer closes dentin tubules and reduces the effect of irrigating solutions, the quality of obturation and outcome of endodontic treatment.

Bias-Free Shear Estimation using Artificial Neural Networks
, 2010 Bias due to imperfect shear calibration is the biggest obstacle when constraints on cosmological parameters are to be extracted from large area weak lensing surveys such as Pan-STARRS-3pi, DES or future satellite missions like Euclid. We demonstrate that
