Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

On the Forward Scattering of Microwave Breast Imaging

International Journal of Biomedical Imaging, 2012
Microwave imaging for breast cancer detection has been of significant interest for the last two decades. Recent studies focus on solving the imaging problem using an inverse scattering approach.

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

Advanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Quantitative Stain Mapping in X‐Ray Virtual Histology

Advanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Nonrelativistic Spin Current Generated Unconventional Spin Hall Magnetoresistance in Altermagnetic RuO2

Advanced Science, EarlyView.
It is reported that the unconventional spin Hall magnetoresistance generated from nonrelativistic spin currents in RuO2 is capable of accurately detecting spin current polarization and disentangling the T̂$\hat{T}$‐odd and T̂$\hat{T}$‐even components of a spin current.
