Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Occluded Face Recognition Using Correntropy-based Nonnegative Matrix Factorization

open access: yes, 2021
Occluded face recognition is one the most interesting problems of applied computer vision. Among many face recognition approaches, the Nonnegative Matrix Factorization (NMF) turns out to be one of the popular techniques especially for part-based learning.

Symmetric Nonnegative Matrix Factorization Based on Box-Constrained Half-Quadratic Optimization

open access: yesIEEE Access, 2020
Nonnegative Matrix Factorization (NMF) based on half-quadratic (HQ) functions was proven effective and robust when dealing with data contaminated by continuous occlusion according to the half-quadratic optimization theory.

Integrative Multi‐Omics Profiling Reveals Age‐Associated Genomic and Tumor Microenvironmental Heterogeneity in Colorectal Cancer

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Integrated multi‐omics analysis defines an age‐resolved molecular–immune framework in colorectal cancer. Early‐onset tumors show reduced APC/KRAS alterations, frequent SMAD4 disruption, enriched PTPRK–RSPO3 fusions, and increased CD4+ memory T cells and mast cells with greater checkpoint responsiveness.

Nanoscale Mapping of Transition Metal Ordering in Individual LiNi0.5Mn1.5O4 Particles Using 4D‐STEM

open access: yesSmall Methods, Volume 10, Issue 18, 23 September 2026.
ABSTRACT The electrochemical performance of the spinel LiNi0.5Mn1.5O4, a high‐voltage positive electrode material for Li‐ion batteries (LIBs), is influenced by the transition metal arrangement in the octahedral network, leading to disordered (Fd3̲m$Fd\underline 3 m$ S.G.) and ordered (P4332 S.G.) structures.
