Broadband Phonon Resonance Spectrum in Host–Guest Resonator Arrays via Nonlocal Coupling

open access: yesSmall Structures, EarlyView.
Introducing nonlocal coupling in host–guest systems induces collective resonance, resulting in a smooth and broadband phonon resonance spectrum. This strategy overcomes the narrowband and antiresonance limitations of local coupling and thus provides a versatile route to manipulate phonon transport.

Large Supramolecular Patterns in Photoactive Chiral Liquid Crystals for Light‐Controllable Soft Micromechanical Systems

open access: yesSmall Structures, EarlyView.
Revolving chiral patterns are induced by an ultraviolet light beam in frustrated films of photoactive chiral nematics. The uniformity and regularity of the rotation depend on the ratio of the pattern size to the diameter of the light spot. The rotation is interrupted when this ratio reaches about eight.

SFNIC: Hybrid Spatial‐Frequency Information for Lightweight Neural Image Compression

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Neural image compression (NIC) has shown remarkable rate‐distortion (R‐D) efficiency. However, the considerable computational and spatial complexity of most NIC methods presents deployment challenges on resource‐constrained devices. We introduce a lightweight neural image compression framework designed to efficiently process both local and ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.
