Abstract: The present disclosure provides a solution for video processing. A method for video processing comprises: selecting, for a conversion between a current video block of a video and a bitstream of the video, a target scheme from a plurality of candidate schemes for adjusting a merge candidate for the current video block; and performing the conversion based on the target scheme, wherein the plurality of candidate schemes comprise at least one of a first set of candidate schemes and a second set of candidate schemes, in each of the first set of candidate schemes, a first motion vector (MV) of the merge candidate is adjusted with a first motion vector difference (MVD), and a second MV of the merge candidate is kept unadjusted, in each of the second set of candidate schemes, the second MV is adjusted with a second MVD, and the first MV is kept unadjusted.

Abstract: A method for extracting germanium based on acid decomposition is provided, including acid decomposition and post-treatment steps, and specifically including: adding an acid to a coal ash for conditioning to obtain a material a; heating the material a to 350° C. to 800° C., and keeping the material a at this temperature for 10 min to 10 h to obtain an acid-decomposed material b; milling the acid-decomposed material b until more than 60% of a milled material has a particle size of less than 200 mesh to obtain a material c; subjecting the material c to distillation to obtain a residual slurry d and a distillation fraction e; and hydrolyzing the distillation fraction e with a dilute hydrochloric acid solution, and then oven-drying to obtain GeO2.

Abstract: An improved disc brake having double-yoke plate and a fixed caliper; an inclined surface is disposed in a key groove on a caliper body; when the caliper body and the upper and lower plates are assembled, the supporting keys of the upper and lower plates of the caliper body are pressed via the inclined surfaces in the key groove, such that the caliper body applies an axial pressure away from a brake disc to the supporting keys during assembly, thus further improving the rigidity of the brake, and reducing the consumption of brake fluid.

Abstract: A method for measuring pole width of a slider of a disk drive includes steps of: getting an original image of the pole surface; calculating the light intensity distribution profile of the original image and determining maximum and minimum light intensity data points of the profile; setting average of the maximum and minimum light intensity data points as a threshold; carrying out quadratic differentiation of the profile to obtain a quadratic differential asymptote; determining cross points between the quadratic differential asymptote and the threshold; calculating the distance between the cross points to obtain an initial pole width; and performing data compensation to the initial pole width to obtain a compensated pole width. The method may also measure the distance between edges of other micro-objects.
