Abstract: Embodiments of the present application provide a video transcoding method, a video display method, an apparatus and an electronic device, which relate to the field of video processing technology. The video transcoding method includes: acquiring a first image in an initial images obtained by stitching multi-channel video images; determining an initial resolution of each of initial sub-images; wherein each initial resolution is not greater than a maximum resolution of input data that can be supported by a preset encoder, and a target resolution of a target sub-image obtained after transcoding each initial sub-image is not greater than a maximum resolution of output data that can be supported by the preset encoder; segmenting a to-be-cut image into respective initial sub-images based on the respective initial resolutions; encoding each initial sub-image according to a target resolution of a target sub-image after transcoding this initial sub-image by using a preset encoder, to obtain each of target code-streams.

Abstract: Provided are human antibodies and fragments thereof having binding specificity to the SARS-CoV-2 spike protein's receptor binding domain (RBD). The antibodies and fragments have strong affinity and potent neutralization ability against the SARS-CoV-2 virus and various mutant forms. Also provided are trimeric antibodies which have further enhanced neutralization capabilities. The antibodies and fragments thus may be used for preventing or treating SARS-CoV-2 viral infection or detecting the presence of the virus in a sample.

Abstract: A material melting device of metal injection molding machine comprises a main feeding cylinder; a plurality of preheating feed cylinders parallel arranged at a lateral side of a main feeding cylinder of a metal injection molding machine; a plurality of material outlets formed at a side of each preheating feed cylinder. The material outlets are communicated to the main feeding cylinder through the guide tubes. Thereby, an inner side of the preheating feed cylinder is pre-heated so as to get preheated grains by adjusting the preheating screw rods in the preheating feed cylinder. Moreover, the preheating feed cylinders can be replaced by feeding funnels and the guide tubes are replaced by heating pipes.

Abstract: An air releasing check structure of a metal injecting machine has a seat rod installed between a rear seat of a feeding screw rod and the extruding head at a front end of the front section. A periphery of the seat rod is enclosed by a check toggle. If the material to be ejected has bubbles so that it is not extruded effectively, the bubbles will flow to the exhausting grooves of the check toggle. Then the bubbles are drained out. Thereby, the bubbles in the material are vented out so that the material becomes dense. When the material becomes dense with high tension, the pressure of material will be greater than the force for buckling the elastic toggles so that the elastic toggles expand. As a result, the elastic toggle will further isolate the exhausting groove. Thereby, the material moves forwards to be ejected from the extruding head.
