  • Publication number: 20210292778
    Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a plant insect pest, such as Coleopteran, Hemiptera, or Lepidopteran plant pest, including a Diabrotica, Leptinotarsa, Phyllotreta, Acyrthosiphan, Bemisia, Halyomorpha, Nezara, or Spodoptera plant pest, decrease the expression of a target sequence in the pest. Disclosed are various target polynucleotides set forth in any one of SEQ ID NOS: 1-398 disclosed herein, or variants and fragments thereof, or complements thereof, wherein a decrease in expression of one or more of the sequences in the target pest controls the pest. Plants, plant parts, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.

  • Publication number: 20200176561
    Abstract: The present invention discloses a cellular structure of a silicon carbide UMOSFET device having surge voltage self-suppression and self-overvoltage protection capabilities. A p-well region of the cellular structure is divided into three layers; the top layer is on the left and right sides of a U-shaped trench and in contact with the U-shaped trench; the middle layer and the bottom layer are respectively constituted by two parts on the left and right sides of the cellular structure, and the left and right parts of the two are not in contact; the distances between the left and right parts of the middle layer and the vertical axis of the cellular structure are greater than the distances between the left and right parts of the bottom layer and the vertical axis of the cellular structure; that is, a JFET structure is introduced to a drain current path of the cellular structure.
