Absorption of Broadband Low‐Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing

Advanced Science, EarlyView.
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Stretchable, Tough, and Luminescent Perovskite Molecular Ferroelectric Composite: Empowering Reliable Self‐Powered Motion Sensing in High Humidity and Subzero Temperatures

Advanced Science, EarlyView.
A flexible molecular ferroelectric composite is fabricated via in situ growth of luminescent DMAA‐MnCl3 ferroelectric crystals within a SEBS/SIS double‐polymer matrix. It delivers 7.54 MPa tensile strength, over 1200% tensile strain, durable piezoelectric motion sensing, and excellent harsh‐environment stability for all‐weather wearable biomechanical ...

Preserving Motor Features by Alternative Re‐Referencing to Remove Heart Artifact on the Stentrode

Advanced Science, EarlyView.
Endovascular brain‐computer interfaces record neural activity from within cerebrovasculature, at the expense of electrocardiogram contamination. Band‐limited independent component analysis separates this heart‐based artifact from task‐relevant neural activity in each frequency band, enabling the reconstruction of cleaner neural recordings without the ...

Harmonic Resonance Theory and HIGGS

“What if the Higgs field proves it doesn’t exist the way we think it does?”This conceptual paper explores an alternative view on fermion mass generation—not through local Yukawa couplings, but via global overlap between extended fermion wavefunctions and the Higgs field. We propose a wavefunction-based mass mechanism, outline a Hamiltonian self-overlap

A Universal Protein Ladder for Standardization of Diverse FRET Assays

Advanced Science, EarlyView.
Translating FRET measurements from in vitro to intracellular environments requires universal benchmarks. We present a modular protein ladder using TPR motifs to harmonize data across diverse platforms. This predictable calibration curve bridges single molecule FRET measurements, with cell based measurements including FLIM‐FRET.
