Abstract: A ventilation method for a high gas working face based on alternating intake and air return in a mine gallery is provided. In this method, an isolated island working face is divided into several sections along a strike direction. A coal pillar is alternately set as a conventional section and a gas-drainage section. Opposite coal pillars in the two mine galleries within the same section are respectively used as the conventional section and the gas-drainage section. Two mine galleries on both sides of the isolated island working face are alternately used as an intake gallery and a return gallery. The coal pillar at the side of the mine gallery as the return gallery is the gas-drainage section. A gas-drainage hole communicating a goaf is provided in the gas-drainage section, so that gas in the goafs at two sides of the isolated island working face can be extracted alternately.

Abstract: An application of potassium ion (K+) channel blocker in preparation of drugs for treating liver fibrosis is provided, which relates to the field of medical technologies. The K+ channel blocker is sotalol, the sotalol is originally used as an antiarrhythmic drug in clinic and has a property of inhibiting K+ channels. Experiments show that sotalol can effectively inhibit liver fibrosis and reduce expression of fibrosis-related protein alpha-smooth muscle actin (?-SMA), specifically by regulating expression and/or function of autophagy and epithelial-mesenchymal transition (EMT) molecules to achieve inhibition of hepatic stellate cell (HSC) fibrosis, so as to provide a new drug choice for clinical treatment of the liver fibrosis.

Abstract: An ion channel blocker for treatment and/or prevention of hepatic fibrosis is provided. Based on the fact that the activation of hepatic stellate cells is an important link in anti-hepatic fibrosis, it is found that gliclazide has the effect of inhibiting the activation of hepatic stellate cells by in vitro and in vivo experiments. Further exploration reveals that gliclazide mainly inhibits the activation of hepatic stellate cells by inhibiting autophagy pathways, and thus the gliclazide can be used to prepare medicaments for treatment and/or prevention of hepatic fibrosis.

Abstract: A method for combined characterization of pore structure includes steps as follows. Firstly, CO2, N2 and high-pressure mercury intrusion porosimetry characterization curves are plotted based on actual measurement data, then, average values of the overlapping range of the CO2 and N2 characterization curves are calculated, and a function yi?=ƒ(x) is fitted. Each pore volume yi? corresponding to each pore diameter xi is calculated, and a curve is plotted with xi as a horizontal coordinate and yi? as a vertical coordinate, thereby obtaining a characterization curve of the overlapping range between CO2 and N2 adsorptions. The same data processing is used to process the overlapping range data of the N2 and high-pressure mercury intrusion porosimetry characterization curves, to obtain the characterization curve between them. The characterization curves are spliced with the original CO2, N2, and high-pressure mercury intrusion porosimetry characterization curves to obtain a combined characterization curve.

Abstract: With rapidly evolving technologies and emerging tools, sports-related videos generated online are rapidly increasing. To automate the sports video editing/highlight generation process, a key task is to precisely recognize and locate events-of-interest in videos. Embodiments herein comprise a two-stage paradigm to detect categories of events and when these events happen in videos. In one or more embodiments, multiple action recognition models extract high-level semantic features, and a transformer-based temporal detection module locates target events. These novel approaches achieved state-of-the-art performance in both action spotting and replay grounding. While presented in the context of sports, it shall be noted that the systems and methods herein may be used for videos comprising other content and events.

Abstract: A JYB-based barter transaction platform where trades between sellers and buyers are denominated in JYB is used to settle all objects and services purchased or sold on the platform. The JYB is a trade measuring currency instead of a circulation currency, and cannot be directly exchanged with a circulation currency. Only when the amount of JYB is insufficient during a trade, can the JYB difference be supplemented by a circulation currency at the conversion rate; in the case of regular settlement of circulation currency, the barter transaction platform collects the amount of circulation currency that has been received and refunded to users by the conversion rate. JYB can replace any circulation currency to achieve real-time barter trade.
