Abstract: A compound, as represented by formula I, as a TLR7 agonist, a method for preparing the compound, and the use of the compound in treating diseases mediated by the TLR7 agonist are provided. Studies on the activity of a human-derived receptor, a TLR7 agonist, show that compounds have a strong agonistic effect on the human-derived receptor, TLR7, and can be used as a foreground compound for treating diseases mediated by the TLR7 agonist.

Abstract: This application provides a system information SI transmission method and apparatus. The method includes: The first terminal device receives a first request message sent by the one or more second terminal devices. The first request message is used to request to obtain M system information blocks SIBs or system information SI messages of a serving cell. The first terminal device determines N destination identifiers corresponding to the M SIBs or SI messages, where N is an integer greater than or equal to 1, and N?M. The first terminal device sends, based on the N destination identifiers, the M SIBs or SI messages to the one or more second terminal devices in a broadcast or multicast manner. According to the method, the SI may be transmitted on an SL in the multicast or broadcast manner. This improves SI transmission efficiency and SI update efficiency.

Abstract: A salt lamp humidifier which has a humidifier base body and a humidifier water tank connected with the humidifier base body to form an air humidifier, and a salt lamp chamber is arranged on the humidifier base body, in which a salt lamp is provided, the salt lamp and the humidifier base body are configured as a retractable structure. The salt lamp is arranged in the humidifier base body or the salt lamp is assembled on the bottom cover to form a retractable concealed structure with reasonable design. The salt lamp salt stone box has a retractable design to facilitate the replacement of salt stones.

Abstract: An atomizer includes a shell, an electronic system and a heating body. The heating body includes an atomization piece of a flat structure and a heating film attached to the bottom surface of the atomization piece. The shell has a receiving chamber. The atomization piece is matched with the bottom of the receiving chamber in shape and is laid at the bottom of the receiving chamber in a sealing manner. The bottom of the receiving chamber is hollowed out, exposing the heating film. The electronic system in the shell is electrically connected with the heating film. A heating body of a columnar structure of existing atomizers is replaced with the atomization piece, and the atomization piece is matched with the bottom of the receiving chamber in shape and is laid at the bottom, so that a surface heating structure easy to clean is formed, liquid is uniformly heated and atomized.

Abstract: A method is described for estimating longitudinal velocity of a vehicle on a road surface. The method includes obtaining a measured value of vehicle acceleration, which is dependent on longitudinal acceleration of the vehicle and vertical acceleration of the vehicle when a slope of the road surface is non-zero. The method includes determining an initial estimate of the slope. The method includes determining a difference between the initial estimate of the slope and a prior estimate of the slope and, based on the difference, setting a current estimate of the slope to be equal to the initial estimate or the prior estimate. The method includes estimating the longitudinal velocity of the vehicle based on the current estimate of the slope and the measured value of vehicle acceleration. The method includes controlling at least one wheel of the plurality of wheels based on the estimated longitudinal velocity of the vehicle.
