Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

Improving the MPC Performance of the Model in Order to Improve the Frequency Stability of the Two-Area Microgrid [PDF]

International Journal of Industrial Electronics, Control and Optimization
: In the context of frequency stability in a two-area microgrid, it is crucial to address the fluctuations in frequency caused by load disturbances. To achieve this, an effective load-frequency control (LFC) system, which serves as the secondary control,

Hailstorm Events Over a Maritime Tropical Region: Environmental Influences on Microphysics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Building on a previous study showing that NetCAPE0C—formulated as CAPE calculated up to the 0° ${}^{\circ}$C isotherm, after subtracting CIN and correcting for water loading—is effective in predicting hail occurrence in maritime tropical (mT) environments, we examined the microphysics to understand why, particularly for ordinary pulse storms ...

Clustering of Right‐Moving Tornadic Supercell Proximity Sounding Profiles Using an Explainable Framework

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract This study demonstrates an explainable machine learning framework for explicitly selecting important environmental features that determine clusters of right‐moving tornadic supercells. Although previous studies have clustered and analyzed proximity sounding profiles associated with tornadic right‐moving supercells, few have identified key ...

SPADE: A Deep Learning Framework for Spatial Mapping and Quantitative Cell–Cell Interaction Inference

Advanced Science, Volume 13, Issue 51, 14 September 2026.
SPADE integrates spatial transcriptomics with single‐cell RNA sequencing by using cell–cell communications (CCC) as a guide for spatial mapping. It improves cell‐type localization, enhances sparse gene‐expression signals, and reveals CCC programs at single‐spot resolution.
