    Abstract: A method for denoising an image, an apparatus, and a computer-readable storage medium. The method includes: dividing a to-be-processed image into a plurality of image areas; for each image area, expanding an edge of the image area to obtain an expanded area; wherein the expanded area comprises the image area and an edge area, and the edge area comprises pixels in another image area adjacent to the image area; for each expanded area, performing denoising processing on the expanded area through a preset algorithm to obtain a denoised expanded area; wherein the denoised expanded area comprises a denoised image area and a denoised edge area; and abandoning the denoised edge area in each denoised expanded area, and retaining and combining all the denoised image areas to form a denoised image.

    Abstract: Provided are composite array electrode, preparation method thereof and use thereof. The composite array electrode comprises a microelectrode array substrate, and a modification layer formed on a surface of a microelectrode of the microelectrode array substrate, wherein the modification layer comprises a plurality of electrically conductive layers arranged at intervals on the surface of the microelectrode, an insulating layer arranged on the surface of the microelectrode except the electrically conductive layers, and wherein material for the electrically conductive layers comprises one or more of nano platinum, nano iridium, conductive polymer and carbon nanotubes. The composite array electrode effectively eliminates the influence of edge effect such that the electric field distributes uniformly on the microelectrode surface of the composite array electrode, significantly improving electrochemical performance and detection capability of the electrode.

    Abstract: The present invention provides a panoramic presentation method and apparatus. The present invention presents a panoramic image by using a combined structure of a single fisheye projector and a spherical screen in hardware, employs a geometrical relationship between a fisheye lens and the position of a viewer and isometric projection transformation, and enables 180° fisheye projection to present 720° environment information to the viewer in the center of the spherical screen, greatly simplifying the image conversion process and realizing zero distortion. According to a 720° panorama one-step generation method based on a single virtual camera in software, complex steps of collecting six images by a plurality of cameras, synthesizing a cube map and then converting the cube map into a panorama are not needed, the vertex position of a scene is directly adjusted in the process from a 3D space to a 2D image.

    Abstract: Disclosed are a detection method for protein liquid-liquid phase separation (LLPS) and use thereof. The method comprises: constructing a first expression vector for expressing an energy donor fluorescent molecule fused to a target protein and a second expression vector for expressing an energy acceptor fluorescent molecule fused to the target protein; transferring both expression vectors into primary cultured cells; stimulating the primary cultured cells while collecting fluorescence microscopic imaging data by using an appropriate fluorescence microscope; calculating a change in Förster resonance energy transfer (FRET) efficiency as a proxy for monitoring the process of LLPS and phase transition of the target protein.

    Abstract: The present invention provides a shape memory material with a chelating system. The shape memory material with the chelating system comprises polyurethane and a metal complex in a mass ratio of 100: (1-10), and the polyurethane is obtained by reaction of the following components by weight percent: 9.0-10.0% of methylenediphenyl diisocyanate, 0-2.0% of chain extender, 0-3.0% of chelating agent, and 87.0-88.0% of polycaprolactone diol. The present invention provides a novel shape memory material polyurethane-manganese dioxide (SMPU-MnO2) chelating material. Collaboration of its mechanical strength, shape memory performance and Mn2+ responsive release is achieved through the chelating system, and shape recovery is performed by means of the photothermal effect of manganese dioxide under remote control of near-infrared light to achieve self-fixed filling of an irregular bone defect part and responsively release manganese ions, so as to achieve a bone repair biological function.
