Patent number: 12382086Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. An apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current coded picture. The prediction information indicates a motion vector predictor index (MVP_idx) for selecting a motion vector predictor in a motion vector predictor list. The processing circuitry determines whether the MVP_idx is smaller than a threshold. When the MVP_idx is determined to be smaller than the threshold, the processing circuitry decodes a motion vector difference (MVD) corresponding to the motion vector predictor and reconstructs the current block based on the motion vector predictor and the MVD. When the MVP_idx is determined to be equal to or larger than the threshold, the processing circuitry reconstructs the current block based on the motion vector predictor without the MVD which is not signaled in the coded video sequence.Type: GrantFiled: October 13, 2021Date of Patent: August 5, 2025Assignee: Tencent America LLCInventors: Meng Xu, Xiang Li, Xiaozhong Xu, Guichun Li, Shan Liu, Xin Zhao

Publication number: 20250223659Abstract: The present disclosure relates to enzymatic cascade reactions for achieving better sensitivity in detecting a target nucleic acid sequence. Several aspects of the disclosure relate to a reaction master mix comprising four major components: a CRISPR enzyme, a guide RNA (gRNA), an aptamer (e.g., an inhibiting aptamer or an activating aptamer) and a “signaling” (i.e., reporter) enzyme. The aptamer interacts with the signaling enzyme and forms a complex, resulting in, e.g., inhibited signaling enzyme activity. When a target is present in the reaction mix, the Cas/guideRNA system becomes activated and preferentially collaterally cleave(s) all nucleic acids in the solution, including the aptamer. Once aptamer gets cleaved, the signaling enzyme is free to produce a signal. In the presence of a substrate, such signaling enzyme activity produces a robust signal that significantly improves the limit-of-detection of other techniques in the art.Type: ApplicationFiled: January 8, 2025Publication date: July 10, 2025Applicant: Roche Molecular Systems, Inc.Inventors: Xiang Li, Yu Tian
