Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Searching for Topological Semi‐Complete Bandgap in Elastic Truss Lattices

open access: yesAdvanced Science, EarlyView.
Ideal gapless nodes within clear bandgaps remain elusive in elastic systems, where degeneracies always hide in trivial bulk bands due to intricate modes. The work proposes a topological semi‐complete bandgap (exhibits a complete bandgap except for the inevitable topological degenerate points) in a 3D elastic truss lattice by tuning a supporting rod ...

On the Correlation Between the SAR Backscatter Modulation and Surface Waves Orbital Velocity

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
A challenging effect in the retrieval of ocean surface currents from synthetic aperture radar (SAR) is the so-called wave-induced Doppler velocity. This effect arises from the correlation between the modulation of the normalized radar cross section (NRCS)

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

On the relativistic Doppler effect for precise velocity determination using GPS [PDF]

open access: yes, 2006
The Doppler effect is the apparent shift in frequency of an electromagnetic signal that is received by an observer moving relative to the source of the signal.

MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

open access: yesAdvanced Electronic Materials, EarlyView.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...
