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

Advanced Science, Volume 13, Issue 25, 4 May 2026.This study identifies vacuole membrane protein 1 (VMP1) as a critical regulator of intestinal epithelial barrier homeostasis. VMP1 facilitates the recruitment of CORO1C to late endosomes, supporting Retromer‐mediated recycling of the tight junction protein Occludin.

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.• The activation of the microglial Hcar2 receptor by niacin initiates intracellular signalling that induces metabolic reprogramming. • This metabolic shift is characterized by increased oxidative phosphorylation. Consequently, microglia polarize from a proinflammatory state toward an anti‐inflammatory, reparative phenotype.

A Bayesian Causal Model for Matrix‐Valued Exposures With Applications to Radiotherapy Planning
Statistics in Medicine, Volume 45, Issue 10-12, May 2026.ABSTRACT In radiotherapy for cancer, organs surrounding the target tumor, known as organs‐at‐risk (OARs), should be protected from excessive radiation to avoid toxicity. Radiation exposure to multiple OARs can be summarized using matrix‐valued dose‐volume histograms (DVH), and understanding the causal relationship between DVHs and toxicity outcomes can
