Dual‐Array Nano Configuration for High‐Performance Metastable β Titanium Alloys

open access: yesAdvanced Science, EarlyView.
This work resolves a fundamental paradox in metastable alloys by establishing a novel dislocation‐phase coupling mechanism, enabling dynamic microstructure control for simultaneous thermal stability and deformability. Geometrically ordered α‐nanograins achieve unprecedented 500°C strength‐ductility synergy (863 MPa UTS, 78.3% elongation).

Interleaved Pulse Width Modulation Based on Modified Carrier in Parallel Operation

open access: yesIEEE Access, 2021
An interleaved pulse width modulation (PWM) can be employed in a parallel operation of three-phase converters because the interleaved PWM increases the equivalent switching frequency and significantly enhances the output current harmonics.

Light Therapy Alleviates Addiction‐Related Symptoms and Reshapes Habenula and Midbrain Pathways

open access: yesAdvanced Science, EarlyView.
This study investigates light therapy for treating Internet Gaming Disorder (IGD). Functional MRI (fMRI) data reveal that light therapy enhances brain connectivity, particularly between the habenula and the medial orbitofrontal cortex (mOFC). These changes are associated with reduced withdrawal symptoms and addiction severity, highlighting the ...

Coincident Fluorescence‐Burst Analysis of Actin Cargo Molecules in Secreted Single Diffusing Extracellular Vesicles From Human Induced Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
This study presents a two‐color FCCS and coincident‐burst analysis platform to quantify actin cargo in dual‐labeled EVs secreted from hiPSCs. The approach tracks secretion dynamics, confirms actin loading, and measures EV size and cargo number, offering insights into cytoskeletal disruption and neuronal differentiation relevant to neurodegenerative ...
