  • Patent number: 12206894
    Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding. An intra-prediction mode for the target block is derived, and intra-prediction for the target block that uses the derived intra-prediction mode is performed. The intra-prediction mode for the target block is derived using an artificial neural network, and an MPM list for the target block is derived using information about the target block, pieces of information about blocks adjacent to the target block, and the artificial neural network. The artificial neural network outputs one or more available intra-prediction modes. Further, the artificial neural network outputs match probabilities for one or more candidate intra-prediction modes, and each of the match probabilities for the candidate intra-prediction modes indicates a probability that the corresponding candidate intra-prediction mode matches the intra-prediction mode for the target block.

  • Publication number: 20230242477
    Abstract: For methane activation, various sulfonation systems using SO3 or H2SO4 have been well studied, however, sulfur dioxide (SO2), a preliminary source of SO3 and H2SO4, has not been used successfully. Herein, we report a novel methane sulfonation method to produce methanesulfonic acid (MSA) utilizing sulfur dioxide by a free radical mechanism. In the presence of H2O2 as a radical initiator, the reaction of SO2 and O2 in trifluoroacetic acid (TFAOH) furnished trifluoroacetylsulfuric acid (TFAOSO3H), which served as the radical propagator to facilitate H-abstraction of methane at low temperatures. In typical reactions, sulfur dioxide was incorporated into MSA in 75% with high selectivity at 60° C.
