Mechanism of Alfalfa in Enhancing Goose Egg Yolk Flavor: An Analysis Based on Metabolomics and Quantitative Lipidomics

open access: yesFood Frontiers, EarlyView.
ABSTRACT Organic egg production requires daily provision of coarse feed, fresh or dried forage, and silage to poultry. This study employed flavoromics, metabolomics, and quantitative lipidomics to investigate the effects of replacing 0% (CK), 10% (T10), and 20% (T20) of the basal diet of laying geese with alfalfa (Medicago sativa L.) on the sensory ...

A strategy for modulation of permittivity in manganese doping to induce lattice distortion

open access: yesInfoMat, EarlyView.
Manganese atoms are doped into the NiCo2O4 spinel structure by atomic substitution, which increases structural stability through the formation of manganese–oxygen bonds. The resulting lattice distortion leads to a significant increase in dielectric permittivity. Achieving an electromagnetic wave reflection loss of −63.40 dB thus provides useful insight

A tunable microwave absorption metamaterial inspired by moths evading bat detection

open access: yesInfoMat, EarlyView.
Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

open access: yesLaser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Frozen Differential Scattering in Reconfigurable Complex Media

open access: yesLaser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...
