  • Patent number: 11303297
    Abstract: A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein. The bit interleaver includes a first memory, a processor, and a second memory. The first memory stores a low-density parity check (LDPC) codeword having a length of 64800 and a code rate of 3/15. The processor generates an interleaved codeword by interleaving the LDPC codeword on a bit group basis. The size of the bit group corresponds to a parallel factor of the LDPC codeword. The second memory provides the interleaved codeword to a modulator for 1024-symbol mapping.

  • Patent number: 11299750
    Abstract: An object of the present invention is to solve problems in terms of stagnation of research on norovirus by providing a cultured transgenic cell or a transgenic animal in which murine norovirus (MNV) can be grown across the barrier of host specificity in mammalian cells, and providing a screening method that uses the cultured transgenic cell or the transgenic animal. The present inventors have found that MNV infection is determined in a cultured transgenic mammalian cell or a mammal possessing the cultured transgenic mammalian cell as its own cell, the cultured transgenic mammalian cell containing one or more species selected from the entirety or a portion of the murine CD300F gene and/or a CD300 family gene having an extracellular domain nucleotide sequence similar to that of the murine CD300F gene. The present inventors have solved the aforementioned problems by providing, for example, a norovirus-related drug screening method on the basis of this finding.

  • 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.
