Abstract: A method and apparatus for improving sensitivity of wafer detection, and a storage medium are provided. The method including: acquiring a gray-scale image of a peripheral circuit region of a wafer; dividing the gray-scale image into at least one pixel region; determining a repeated image region in each pixel region, in which the repeated image region is a region with N*M pixels where M pixels on a same column in the repeated image region have a same gray-scale value, and N and M are integers greater than 0; and determining position information where interference superposition occurs in the peripheral circuit region of the wafer according to all repeated image regions in the gray-scale image.

Abstract: Disclosed is a data sharing method and an electronic device. The data sharing method includes: acquiring encrypted data to be analyzed, selected by a data user, in a data sharing platform; and decrypting, by using a trusted execution program, the encrypted data to be analyzed to obtain decrypted data, and performing, by using the trusted execution program, data analysis on the decrypted data, to obtain a data analysis result of the encrypted data to be analyzed, where the trusted execution program is provided with identity authentication information of the data user set in a built-in manner, and an execution process of the trusted execution program is invisible to the data user, which can ensure the security of shared data in a process of data sharing and improve the efficiency of data analysis.

Abstract: Provided are a taxadiene synthase TcTS2, an encoding nucleotide sequence and use thereof. The amino acid sequence of TcTS2 includes or consists of: (a) an amino acid sequence represented by SEQ ID NO: 1; or (b) a functional homologous sequence having at least 80% sequence similarity with the amino acid sequence represented by SEQ ID NO: 1; or (c) an amino acid sequence having TcTS2 activity with addition, deletion, or substitution of one or more amino acids in the amino acid sequence represented by SEQ ID NO: 1. TcTS2 and the nucleotide sequence encoding the TcTS2 provide new gene resources for improving the yield of taxol, and they may be used for modifying chassis hosts by plant genetic engineering and metabolic engineering strategies to produce taxol and the intermediates thereof etc., thereby having significant economic and social value.

Abstract: Provided is a polynucleotide for identifying a male or female Ginkgo biloba plant, comprising or consisting of the following sequence: 1) the nucleotide sequence represented by SEQ ID NO: 5; or 2) a complementary, degenerate or homologous sequence of the sequence represented by SEQ ID NO: 5; or 3) a polynucleotide hybridizing to the nucleotide sequence represented by SEQ ID NO: 5 under stringent conditions or a complementary sequence thereof; 4) the coding sequence of any one of the sequences of the above 1)-3); or 5) a nucleotide sequence being identical to more than 10 bp contiguous nucleotides in any one of the sequences of the above 1)-4). The polynucleotide provided herein is unique to a male Ginkgo biloba plant, and it may be used to identify a male or female Ginkgo biloba plant; this identification method has the advantages of stable and accurate results, good repeatability and fast detection, thereby providing the basis for identifying a male or female Ginkgo biloba plant by molecular markers.
