Abstract: A method for displaying an associated term includes obtaining a search term entered in a search bar; determining an associated term corresponding to the search term; determining an application corresponding to the associated term; and displaying the associated term and an identifier corresponding to the associated term, where the identifier is used to open the application corresponding to the associated term corresponding to the identifier. The method for displaying the associated term may facilitate interaction between a user and another application on the terminal device when the user performs searching in a search engine of the terminal device.

Abstract: The present specification discloses video matching. In a computer-implemented method, a plurality of feature vectors of a target video is obtained. A candidate video similar to the target video is retrieved from a video database based on the plurality of feature vectors of the target video. A time domain similarity matrix feature map is constructed between the target video and the candidate video based on the target video and the candidate video. Using the time domain similarity matrix feature map as an input into a deep learning detection model, a video segment matching the target video in the candidate video and a corresponding similarity is output.

Abstract: The present disclosure provides a herbicide composition and a preparation method and an application method thereof, and relates to the technical field of herbicides. The herbicide composition includes pinoxaden and a cyclic lactone compound. The cyclic lactone compound is five-membered cyclic lactone and/or six-membered cyclic lactone. The herbicide composition solves the technical problems of poor chemical stability and precipitation due to crystallization at low temperature of existing pinoxaden emulsifiable concentrate formulations. In the herbicide composition, the cyclic lactone compound is used in combination with the pinoxaden, such that not only the solubility of the pinoxaden is improved, but also a chemical stabilization effect of the pinoxaden is effectively improved, and the problems of precipitation due to crystallization at low temperature and chemical stability of the pinoxaden emulsifiable concentrate formulations are solved.

Abstract: A method of a shale gas reservoir stimulation by oxidation-induced rock burst includes performing a hydraulic fracturing stimulation on a shale gas well to be fractured; during the hydraulic fracturing, successively pumping slick water A, oxidizing fluid, glue liquid-containing slick water, catalytic decomposition fluid, and slick water B in a form of liquid slug. In the present invention, methane released by fracturing by the slick water A is mixed with oxygen generated by decomposition of hydrogen peroxide in the oxidizing fluid to induce oxidation-induced rock burst. Based on the physical properties and chemical thermodynamic properties of shale, a calculation method for the amount of fracturing fluid used and the radius of oxidation-induced rock burst is proposed, thereby realizing safe, efficient, and non-destructive multi-scale stimulation of hydraulic fractures-burst fractures-dissolution pores and fractures.

Abstract: A cotton molecular breeding method includes (1) obtaining a chr.7 single QTL segment substitution line with high fiber strength, and (2) using the obtained chr.7 single QTL segment substitution line as a non-recurrent parent () to cross with a recurrent parent (?) to obtain an F1 generation. Then (3) the F1 generation is back-crossed with the recurrent parent to obtain a BC1F1 generation, and (4) plants of the BC1F1 generation are screened for plants carrying the chr.7 single QTL segment, and then the screened plants are back-crossed with the recurrent parent for 2-4 times to obtain a BCnF1 generation. The method also includes (5) screening plants of the BCnF1 generation for plants carrying the chr.7 single QTL segment, and selfing the screened plants for 1-3 times to obtain a bred line BCnFm having the high cotton fiber strength.

Abstract: A method of preparing collagen active peptides with antiproliferative activity against cancer cells. The collagen active peptides are obtained by hydrolysis of papain and trypsin and a specific purifying process. The collagen active peptides have antiproliferative activity against cancer cells, such as ovarian carcinoma cells including SKOV3, OVCAR3, 436 and SRO82 and the prostate cancer cells including PC3, LnCAPC1, and LnCAPC2.
