Abstract: The present disclosure discloses a trajectory generation method, apparatus, electronic device, storage medium and program, wherein the method includes: acquiring driving-related data corresponding to a current vehicle; inputting first driving-related data in the driving-related data to a pre-created target trajectory generation model to obtain a candidate driving trajectory corresponding to the current vehicle; inputting second driving-related data in the driving-related data into a pre-created target driving correction model to obtain corresponding driving correction information; and correcting the candidate driving trajectory based on the driving correction information to obtain a corresponding target driving trajectory, such that the current vehicle automatically drives according to the target driving trajectory.

Abstract: The present disclosure relates to the technical field of medicine, in particular to a furan-aspidospermine dimer or a pharmaceutically acceptable salt thereof, and a preparation method, use and a pharmaceutical composition. In the present disclosure, the furan-aspidospermine dimer or a pharmaceutically acceptable salt thereof can activate an immune response by increasing a proportion of T lymphocytes and enhance a function of the immune response.

Abstract: The present application provides a metallocene compound, and a preparation method and application thereof. The metallocene compound of the present application includes a structure as shown in Formula a, where Ar is selected from a substituted or unsubstituted C6-C30 aryl; Cp? is selected from a substituted or unsubstituted cyclopentadienyl, indenyl, or fluorenyl; X is at least one of halogen, substituted or unsubstituted C1-C30 alkyl, alkoxy, substituted or unsubstituted C2-C30 dialkylamino, alkenyl, and substituted or unsubstituted C6-C30 aryl; and M is a transition metal element. The metallocene compound is suitable for catalyzing a C6-C30 long straight chain ?-olefin raw material and also a mixed long branched chain non-terminal olefin raw material, and may obtain a polymerization product with a target molecular weight according to demand.
