Abstract: This application provides a bullet-screen comment display method, where the bullet-screen comment display method includes: determining bullet-screen comment area basic information corresponding to a target bullet-screen comment from a target picture; identifying an invalid pixel set of the target picture; determining a bullet-screen comment filling area corresponding to the target bullet-screen comment based on the bullet-screen comment area basic information and the invalid pixel set; and filling the bullet-screen comment filling area with the target bullet-screen comment.

Abstract: A method for constructing a multistage network includes: deploying a plurality of nodes; constructing the upper network with at least one node of the plurality of nodes; and in response to determining there is an isolated node, determining an intermediate node for the isolated node and adding the isolated node into the upper network or one of the at least one sub-network according to the intermediate node.

Abstract: The robust dispatch method for flexibility resources of large-scale data center microgrid clusters characterizes overall scheduling capacity of multiple flexibility resources in each data center microgrid by establishing a virtual battery model, constructs an equivalent model of scheduling capacity of data center microgrid cluster based on constraint space superposition methods of Minkowski summation, and fully exploits flexibility of output power regulation of distributed generator sets and energy storage of the data center microgrid cluster as well as demand response characteristics of loads, so as to obtain regulation domain of aggregate power of the data center microgrid cluster.

Abstract: The present invention discloses powdered oil based on an olesome emusion and a preparation method and an application thereof. The preparation method includes the following steps: preparation of olesome emulsion of an oil stock, addition of a wall material and spray drying. The preparation method for the powdered oil provided by the present invention is based on an olesome emulsion system; and compared with the traditional preparation process for the powdered oil, the preparation method has many advantages that the prepared olesome emulsion does not contain hydrogenated vegetable oil and an exogenous emulsifier, is high in content of active oil accompaniments, and has an embedding rate close to 100 percent, a low production cost, strong storage stability and a certain natural oil stock flavor.

Abstract: An N-(3-hydroxypyridine-2-carbonyl)glycine-based antitumor drug sensitizer and an application thereof are provided. In the present disclosure, a compound of formula (I) can down-regulate PD-L1 of tumor cells, promote polarization of macrophages from M2 to M1, inhibit an expression of indoleamine 2,3-dioxygenase, and improve an immunotherapy curative effect. The compound can also reduce the expression of hypoxia-inducible factor-1? in tumor cells, down-regulate an expression of P-glycoprotein, enhance the killing effect of a chemotherapeutic drug on tumor cells, and enhance immunogenic cell death. The compound of formula (1) has a significantly improved antitumor effect after being used in combination with a chemotherapeutic drug and shows a desirable prospect for use.

Abstract: The present invention relates to the technical field of natural medicines, and in particular to a triterpenoid compound with an effect of improving glucose and lipid metabolism disorders, and preparation and application thereof. A novel triterpenoid compound was obtained by separation from Momordica charantia L. for the first time in the present invention. Studies on a mouse primary hepatocyte model and a 3T3-L1 preadipocyte model show that the novel triterpenoid compound in the present invention has activity of regulating glucose and lipid metabolism, and after combination with known triterpenoid compound Momordicoside G, the activity of regulating glucose and lipid metabolism is significantly higher than that of a single compound at the same dose, indicating that the novel triterpenoid compound and a complex thereof in the present invention can be used to improve glucose and lipid metabolism disorders and provide a new way for diabetes treatment.

Abstract: A method for stabilizing rice bran with complex enzyme involving enzymatic hydrolysis combined with thermal processing to stabilize rice bran, includes compounding at least one of glycosyl hydrolases such as cellulase, hemicellulase and alpha amylase into a complex enzyme solution, and performing enzymatic hydrolysis on the rice bran with the complex enzyme solution, and after enzymatic hydrolysis, performing thermal processing and inactivating enzyme treatment on rice bran using the moist-heat method, microwave method and/or extrusion expansion method, to prepare the stabilized rice bran. From the perspective of reducing bound lipase from rice bran, the glycosyl hydrolase is used to catalyze conversion of bound lipase in rice bran into free lipase, thereby effectively improving inactivation efficiency of rice bran lipase. The rice bran prepared using the method has characteristics of low residual activity of lipase and long shelf life, and may be directly applied to industries such as food and cosmetics.

Abstract: A high-hardness composite oxide dispersion-strengthened tungsten alloy and a preparation method thereof are disclosed. The high-hardness composite oxide dispersion-strengthened tungsten alloy consists essentially of a tungsten phase, and nano-scale Y2O3 and ZrO2 particles dispersed in the tungsten phase, wherein there is a Y—Zr—O ternary phase structure at a coherent/semi-coherent interface.
