Recently data-driven image inpainting methods have made inspiring progress, impacting fundamental editing tasks such as object removal and damaged repairing. These are more effective than classic approaches, however, due to memory limitations they can only handle low-resolution inputs, typically smaller 1K. Meanwhile, the resolution of photos captured with mobile devices increases up 8K. Naive up-sampling inpainted result merely yield a large yet blurry result. Whereas, adding high-frequency...

This paper analyzes the coupling modes when multiple hairpin resonators are coupled. Three kinds of current distribution and direction states exist in coupled resonators: along clockwise direction, counterclockwise no density distribution. Different combinations these lead to different modes. In order distinguish modes, auxiliary lines introduced between each two denote mode, this method is theoretically based on analysis eigenvector matrix. A simple effective technique construct multi-mode...

Between Snyder's quantized space-time model in de Sitter space of momenta and the dS special relativity on dS-spacetime radius R with Beltrami coordinates, there is a one-to-one dual correspondence supported by minimum uncertainty-like argument. Together Planck length ℓP, ≃ (3/Λ)1/2 should be fundamental constant. They lead to dimensionless constant g ∼ ℓPR−1 = (Gℏc−3Λ/3)1/2 10−61. These indicate that physics at these two scales each other in-between gravity local dS-invariance characterized...
