Transient Amplitude Modulation of Alpha-Band Oscillations by Short-Time Intermittent Closed-Loop tACS

Frontiers in Human Neuroscience, 2020
Non-invasive brain stimulation (NIBS) techniques such as transcranial alternating current stimulation (tACS) have recently become extensively utilized due to their potential to modulate ongoing neuronal oscillatory activity and consequently to induce ...

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Reduction of somatosensory functional connectivity by transcranial alternating current stimulation at endogenous mu-frequency

NeuroImage, 2020
Alpha, the most prominent human brain rhythm, might reflect a mechanism of functional inhibition for gating neural processing. This concept has been derived predominantly from local measures of inhibition, while large-scale network mechanisms to guide ...

Preparation of Dispersion-Strengthened Coppers with NbC and TaC by Mechanical Alloying

Materials Transactions, JIM, 1991
To prepare a dispersion-strengthened copper-based alloy, mechanical alloying was carried out using pure copper, niobium, tantalum and graphite powders. After mechanical alloying for 144.0 ks,a Cu-Nb-C solid solution+NbC mixture powder and a Cu-Ta-C solid solution+Ta+TaC mixture powder were obtained inthe Cu-Nb-C and Cu-Ta-C systems, respectively. These

Inhaled Angiopoietin‐Like 4 Antisense Oligonucleotide Therapy for Lung Injury and Fibrosis

Advanced Science, EarlyView.
Inhaled antisense oligonucleotides targeting ANGPTL4 attenuate inflammation, preserve barrier integrity, and reduce fibrosis in both infectious and sterile lung injury models. Integrated transcriptomic analysis reveals a conserved ANGPTL4‐regulated gene network coordinating hypoxic, inflammatory, apoptotic, and stress‐response pathways.
