  • Patent number: 11012707
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry decodes prediction information for a first block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that determines a first motion vector for the first block from a motion vector predictor. The processing circuitry then constructs, in responses to the inter prediction mode, a candidate list of candidate motion vector predictors with an exclusion from a second block that requires an operation to finalize a second motion vector for the second block in a motion vector derivation. Then, the processing circuitry determines, based on the candidate list, the first motion vector for the first block, and reconstructs the first block according to the first motion vector for the first block.

    Abstract: The present invention discloses a maternal haploid major inducing gene in maize and application thereof and also discloses a major gene for inducing the production of maize maternal haploid and its application in double haploid (DH) breeding. This gene encodes a phospholipase (PLA) and the nucleotide sequence thereof is SEQ ID NO: 1. This gene has a maternal haploid inducing ability during selfing or the hybridization of the material as a paternal and other maize material, after a mutation occurred in the coding region. The present invention obtains a series of allelic mutations of the gene for the first time, and proves its maternal haploid induction function by selfing and hybridization. The acquisition of the maternal haploid has important theoretical and practical significance for haploid breeding (DH) and related research.

  • Publication number: 20210143057
    Abstract: The present disclosure discloses an array substrate and a preparation method thereof. After a first passivation layer is formed, residual gas is directly drawn out of a closed chamber to prevent the residual gas from reacting to form an unstable layer on the first passivation layer. Furthermore, after the residual gas is drawn out, a preset gas fills the closed chamber, and is retained for a preset time period and then drawn out. The retaining of the preset gas can effectively alleviate the damage to the passivation layer by static electricity.

  • Patent number: 11006150
    Abstract: A method of video decoding can include receiving a bit stream including coded bits of bins of syntax elements. The syntax elements are of various types that correspond to transform coefficients of a transform block in a coded picture. Context modeling is performed to determine a context model for each bin of the syntax elements. In a given frequency region of the transform block, for one type of the syntax elements, a group of the transform coefficients having different template magnitudes within a predetermined range share a same context model, or one of the transform coefficients uses the same context model for possible different template magnitudes of the one of the transform coefficients. The possible different template magnitudes are within the predetermined range. The coded bits are decoded based on the context models determined for each bin of the syntax elements to determine the bins of the syntax elements.
