  • Method and device for acquiring fetal fraction of cell-free DNA, storage medium and electronic device
    Publication number: 20200048714
    Abstract: Disclosed are a method and a device for acquiring the fetal fraction of cfDNA, a storage medium and an electronic device. The method comprises: acquiring sequencing data of a sample taken from a mother pregnant with a fetus; establishing a joint probability distribution model of the maternal and fetal genotypes, the joint probability distribution model containing one or more factors affecting the read heterozygosity, the percentage of the read heterozygosity being the ratio of the number of SNPs covered by different bases to the total number of SNPs covered by more than one reads in the sequencing data; substituting the values of the one or more factors and of the acquired read heterozygosity into the established joint probability distribution model; and obtaining the fetal fraction of cfDNA by maximum likelihood estimation of the joint probability distribution model.

  • Fusarium chitin synthase gene chs3b and the use thereof
    Patent number: 10392631
    Abstract: The present invention discloses RNAi constructs derived from a Fusarium chitin synthase gene Chs3b, which has a nucleotide sequence as shown by SEQ ID NO: 1. Five distinct RNAi vectors are constructed for 5 different segments of the Chs3b gene (named Chs3b-1, 2, 3, 4, and 5, respectively), and separately transformed into Fusarium. It is found that siRiNAs in the transformed Fusarium shows a significant inhibition in fungal growth, development, and pathogenicity. The expression of the RNAi vectors against Chs3b in plants may inhibit the infection of Fusarium and improve the resistance of the transgenic plants to Fusarium head blight.

  • METHOD AND SYSTEM FOR SWITCHING ROLE OF USB OTG DEVICE AND OTG DEVICE THEREOF
    Publication number: 20170255585
    Abstract: A method and system of switching a role of a Universal Serial Bus (USB) On-The-Go (OTG) device and a USB OTG device are provided. According to the method, when the USB OTG device receives a Host Negotiation Protocol (HNP) request sent from a link-partner, an OTG controller of the USB OTG device is reset. The state of an ID-pin detection end which is used by the OTG controller to detect a type of plug of a USB cable is modified to switch the role of the USB OTG device between a host and a peripheral.
