Advanced Science, EarlyView.This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Minimum mass sizing of a large low-aspect ratio airframe for flutter-free performance [PDF]
A procedure for sizing an airframe for flutter-free performance is demonstrated on a large, flexible supersonic transport aircraft. The procedure is based on using a two level reduced basis or modal technique for reducing the computational cost of ...

RAB5A Promotes Active Fluid Wetting by Reprogramming Breast Cancer Spheroid Mechanics
Advanced Science, EarlyView.RAB5A‐mediated unjamming enhances active wetting through distinct biomechanical processes: a) upregulation of specific integrin subunits, enhanced focal adhesions kinetics and activity; b) supracellular organization relying on nanoscale integrin clustering, and the formation of a stiff and collective actin cable; and c) softening of the spheroid core ...

Advanced Science, EarlyView.FA directly binds to residue H378 of DDX6 and promotes its interaction with HSC70, leading to CMA degradation of DDX6, thereby impairing GSK‐3β/β‐catenin signaling, inhibiting ABC transporter proteins, and enhancing chemosensitivity. Abstract ABC transporter protein‐mediated drug efflux is a significant contributor to induced resistance in breast ...

Advanced Science, EarlyView.This study presents an effective method for fabricating millimeter‐scale continuous in‐plane head‐to‐head charged domain walls by controlling the growth of the Na0.5Bi0.5TiO3 film. The formation of antiphase boundaries plays a crucial role in stabilizing the charged domain walls. Atomic‐scale insights reveal that the dynamic coupling among polarization,

Evaluation of four subcritical response methods for on-line prediction flutter onset in wind-tunnel tests [PDF]
The methods were evaluated for use in tests where the flutter model is excited solely by airstream turbulence. The methods were: randomdec, power-spectral-density, peak-hold, and cross-spectrum.

Wind Tunnel Measurements for Flutter of a Long-Afterbody Bridge Deck
Italian National Conference on Sensors, 2017 Bridges are an important component of transportation. Flutter is a self-excited, large amplitude vibration, which may lead to collapse of bridges. It must be understood and avoided.
