Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced 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,

Acoustofluidic Patterning for Improved Microtissue Histology

open access: yesAdvanced NanoBiomed Research, EarlyView.
Microtissue histology is widely used to characterize microtissue phenotype and morphology. However, conventional microtissue histology workflows are inefficient and time‐consuming. This work introduces a novel embedding technique that uses acoustofluidics to improve the efficiency of microtissue histology and reduce the time required for data analysis.

Effects of Holmium Additions on Microstructure and Properties of A356 Aluminum Alloys

open access: yesMetals, 2018
Sr-modification of A356 alloys has distinct shortages due to the volatilization and oxidation during remelting and pouring, which often reduce the modification efficiency and mechanical properties of the alloys.
