  • Patent number: 11408890
    Abstract: The present invention leverages the techniques for expansion microscopy (ExM) to provide improved high-throughput super-resolution whole-organ imaging methodology to image protein architectures over whole organs with nanoscale resolution by using high-throughput microscopes in combination with samples that have been iteratively expanded more than once, in a method referred to herein as “iterative expansion microscopy” (iExM). In the ExM method, biological samples of interest are permeated with a swellable material that results in the sample becoming embedded in the swellable material, and then the sample can be expanded isotropically in three dimensions The process of iteratively expanding the samples can be applied to samples that have been already expanded using ExM techniques one or more additional times to iteratively expand them such that, for example, a 5-fold expanded specimen can be expanded again 3- to 4-fold, resulting in as much as a 17- to 19-fold or more linear expansion.

    Abstract: Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. In a method, whether an adaptive color transform (ACT) is enabled for a current block is determined. A maximum transform size is determined based on whether the ACT is enabled for the current block. Whether a subblock transform (SBT) is applied to the current block is determined based at least on the maximum transform size. Further, the SBT is performed on the current block based on the SBT being determined to be applied to the current block.

  • Publication number: 20220210427
    Abstract: Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that partitions a current block of a current picture based on a geometric partitioning mode (GPM). The current block is partitioned into two partitions in the GPM mode. Each of the partitions is associated with a respective predictor. A weighting index for a sample of the current block is determined based on a position of the sample. A weighting factor is calculated based on the weighting index of the sample according to an equation that converts the weighting index to the weighting factor. The sample is encoded based on the weighting factor and the predictor corresponding to the sample.

  • Patent number: 11300709
    Abstract: The present invention relates to a method for determining a surface runoff yield in a vegetation-covered area. The present invention improves and integrates a water conservation model with a Zhang's model based on remote sensing data. The present invention constructs a new method for calculating a surface runoff yield in a vegetation-covered area on a spatial pixel scale based on a water balance equation of the vegetation-covered area. This method utilizes real-time dynamic multi-temporal remote sensing data to calculate a vegetation canopy interception water storage, a vegetation litterfall interception water storage, a soil water storage change, a vegetation water conservation, a vegetation evapotranspiration and a vegetation runoff yield. The method realizes the long-term dynamic estimation of the surface runoff yield in regional and global vegetation-covered areas on a spatial pixel scale. It has the advantages of being efficient, fast, accurate, and applicable to large-scale vegetation-covered areas.
