The application discloses application of ginsenoside Rb1 in preparation of biological products for improving liver aging and abnormal lipid metabolism. The application research finds that ginsenoside Rb1 (20 mg / kg) can significantly improve the aging phenotype and lipid metabolism disorder of the aging liver through multi-target synergistic effect, and the mechanism is related to inhibition of lipid synthesis, improvement of lipid transport and promotion of lipid oxidation. The application provides a new drug candidate and action mechanism for intervention of aging-related liver diseases such as MASLD / MASH, and has an important clinical application prospect.

This invention provides a method, system, and medium for channel prediction in a massive MIMO TDD system using a base-extended extrapolation model. The method includes: modeling the uplink channel using a base-extended model, representing the uplink channel as a small number of unknown BEM coefficients, and reconstructing the uplink channel by estimating these unknown BEM coefficients; representing the estimated uplink channel as a linear combination of a discrete ellipsoidal BEM and its corresponding coefficients to reduce the complexity of downlink channel prediction; predicting the coefficients of a downlink time-varying DPS-BEM, and using the predicted DPS-BEM coefficients for downlink channel recovery. This invention alleviates the channel aging problem in massive MIMO TDD systems.

This invention belongs to the field of electronic component technology, and discloses a SnTe material for a nitrogen dioxide gas sensor, its preparation process, and its application. The SnTe material is synthesized via a solvothermal method. The nitrogen dioxide gas sensor mainly consists of a gas-sensitive material and gold interdigitated electrodes. The gas-sensitive material is coated on the surface of the gold interdigitated electrodes with a coating thickness of approximately 15mm to 75mm. The gas-sensitive material is SnTe. This invention provides a simple, low-cost, safe, and controllable TMDC nanomaterial preparation scheme. Using ethanolamine as a solvent and coordinating agent, and potassium hydroxide aqueous solution as a tellurium source activator, this invention synthesizes SnTe nanomaterials in one step via a solvothermal method. The SnTe nanomaterials prepared by this invention achieve a small nanoscale size. A large number of small-sized nanomaterials can effectively increase the sufficient contact between the material and gas molecules, improving the residence rate of gas molecules on the nanomaterial surface.
