AN EQUILIBRIUM SITUATION IN A PATROLLING GAME WITH A TRACKING CAMERA

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
Equilibrium situations in a problem of patrolling on a graph were obtained using game theory methods. The solution of the game was found for a graph modeling the flux of information from data source to sink.

Single‐Cell RNA Sequencing Identifies MMP11+ Cancer‐Associated Fibroblasts as Drivers of Angiogenesis and Bladder Cancer Progression

Advanced Science, EarlyView.
Single‐cell RNA sequencing identifies MMP11⁺ CAFs as pro‐angiogenic cells accumulating during bladder cancer progression. These cells promote angiogenesis by regulating ESM1⁺ tip endothelial cells and recruiting SPP1⁺ macrophages. Tumor‐derived BMP2 promotes their activation.
