A Near‐Field Coupling Array Enables Parallel Imaging and SNR Gain in MRI

open access: yesAdvanced Science, EarlyView.
This paper proposes a metasurface‐based radiofrequency (RF) coil architecture, providing a universal theoretical framework for the application of decoupled metasurface arrays in magnetic resonance imaging, with potential to address wireless connectivity issues in magnetic resonance imaging RF coils.

RAB5A Promotes Active Fluid Wetting by Reprogramming Breast Cancer Spheroid Mechanics

open access: yesAdvanced 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 ...

Mechanical and Electrical Properties of Free‐standing Polycrystal Diamond Membranes

open access: yesAdvanced Science, EarlyView.
We demonstrate a novel approach for synthesizing free‐standing and transferable polycrystalline diamond membranes (PCDm). Two types of PCDm cantilevers—Top‐Surface‐Up (TSU) and Bottom‐Surface‐Up (BSU)—are fabricated and systematically analyzed for mechanical and electrical properties, including elastic modulus, Bandgap, sheet resistance under the ...

Dedifferentiation and Transfer in Executive Function and Math Ability Following a Five‐Year Abacus Training in Schoolchildren

open access: yesAdvanced Science, EarlyView.
While cognitive development typically exhibits differentiation, marked by decreasing inter‐domain correlations, this study demonstrates that five‐year abacus training is associated with de‐differentiation of executive function and mathematical ability in school‐aged children.
