In this talk we describe the order-$\as$ corrections to the total cross section and to jet rates in $\gamma^* \gamma^* \to$ hadrons for the process $\epem\to\epem +$ hadrons. We use a next-to-leading order general-purpose partonic Monte…
Clear imaging under hazy conditions is a critical task. Prior-based and neural methods have improved results. However, they operate on RGB frames, which suffer from limited dynamic range. Therefore, dehazing remains ill-posed and can erase…
