Abstract: Disclosed is a proteomics sample preparation device, comprising a pipette tip, an ion exchange resin filler and a solid-phase extraction membrane. The solid-phase extraction membrane is filled into the lower end of the pipette tip, and the ion exchange resin filler is filled into the lower end of the pipette tip and is located above the solid-phase extraction membrane. The ion exchange resin filler is a strong cation exchange resin filler or a strong anion exchange resin filler. Disclosed is a protein chromatographic separation platform comprising the proteomic reactor and a liquid chromatography-mass spectrometer. Disclosed is the use of the proteomics reactor and protein chromatographic separation platform in the protein identification and protein quantitative analysis of a cell, a tissue or a blood sample.

Abstract: The present disclosure discloses a method for automatically identifying south troughs by improved Laplace and relates to the technical field of meteorology. The method includes the following steps: acquiring grid data of a geopotential height field; calculating a gradient field of the geopotential height field in an x direction; searching for a turning point where a gradient value turned from being negative to being positive, and cleaning the gradient field; calculating a divergence of the x direction to obtain an improved Laplacian numerical value L?; performing 0,1 binarization processing on the L? to obtain a black-and-white image and a plurality of targets of potential troughs, merging the black-and-white image and the plurality of targets of the potential troughs by expansion, recovering original scale through erosion, and selecting an effective target through an angle of direction of a contour and an axial ratio.

Abstract: An image processing method includes an electronic device configured to perform style migration processing on a first image sequence based on a target migration style by using a fused style migration model into which a plurality of single-style migration models is fused in order to obtain a second image sequence. A style of a 1st frame of image to a style of a last frame of image in the second image sequence change in a first style order in styles of output images of the plurality of single-style migration models. The first image sequence may be from a video shot by using the electronic device. The electronic device may save a plurality of frames of images in the second image sequence as a video. The video may present an effect of rapid time lapse during play.

Abstract: The present disclosure discloses near-eye display method and apparatus based on human visual characteristics, and the method includes: dividing a near-eye display screen into n display subregions; acquiring critical spatial frequencies corresponding to the n display subregions respectively; creating and rendering corresponding video image data of n layers for the n display subregions from an input video image according to the critical spatial frequencies corresponding to the n display subregions respectively; transmitting the video image data of the n layers to the near-eye display; and finally, performing reconstruction on and stitching the video image data of the n layers to generate an image which accords with a human gaze effect, and displaying the image in the display screen.
