SAR Target Recognition via Incremental Nonnegative Matrix Factorization

Remote Sensing, 2018
In synthetic aperture radar (SAR) target recognition, the amount of target data increases continuously, and thus SAR automatic target recognition (ATR) systems are required to provide updated feature models in real time.

Immunoregulatory Roles of Tumor‐Originated Pericytes Identified by Single‐Cell Analysis in Glioblastoma

Advanced Science, Volume 12, Issue 47, December 18, 2025.
The origin and functional heterogeneity of pericytes in glioblastoma (GBM) remain unclear. This study identifies tumor‐originated pericytes (T‐PCs) and normal‐originated pericytes as two distinctive populations in human GBM using single‐cell RNA‐sequencing.

Posttransplantation clonal dynamics of hematopoietic stem cells carrying prenatal and early‐life DNMT3A mutations

HemaSphere, Volume 9, Issue 12, December 2025.
Abstract Clonal hematopoiesis (CH), a prevalent and premalignant state in the elderly, has been detected in young individuals under selective pressures such as hematopoietic cell transplantation (HCT). However, the origin of CH and mutational processes underlying CH driver mutations in young blood systems remain unclear.
