Switchable Bidirectional Sound Absorption Via Exceptional Point Modulation in Acoustic Metastructures with Interleaved Resonator Coupling

open access: yesAdvanced Science, EarlyView.
A switchable bidirectional acoustic metastructure is proposed, enabling broadband and frequency‐selective absorption via interleaved resonator coupling and exceptional point modulation. It outperforms traditional unidirectional designs, offering compact, efficient sound control from both directions and establishing a generalized framework for extending

Design Principles for Deployable Fibers Inspired by Hagfish Defense

open access: yesAdvanced Science, EarlyView.
Hagfish slime deploys fibers from coiled skeins to form an ultra‐dilute, water‐trapping network. Inspired by this mechanism, design principles are established for synthetic skeins, fabricated with tightly coiled fibers that unravel under flow. These synthetic skeins demonstrate deployable fibrous networks, highlighting generalizable strategies for ...

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

open access: yesAdvanced Science, EarlyView.
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

Self‐Supervised Learning‐Based Framework for Speckle Reduction of Optical Coherence Tomography Images Using Frame Interpolation

open access: yesAdvanced Intelligent Systems, EarlyView.
In summary, a self‐supervised end‐to‐end framework for OCT image despeckling is proposed, without access to unpaired noisy–clean images or paired noisy–noisy images for training. The despeckling performance has been evaluated on 150 subjects from five retina datasets (121 subjects) and one middle ear dataset (29 subjects). Optical coherence tomography (

An Existence Theorem for a Nonlocal Global Pandemic Model for Insect-Borne Diseases

open access: yesInternational Journal of Differential Equations, 2014
We construct and analyze a nonlocal global pandemic model that comprises a system of two nonlocal integrodifferential equations (functional differential equations) and an ordinary differential equation.
