  • Publication number: 20250092425
    Abstract: The present disclosure belongs to the technical field of gene editing, and specifically provides a FgTad2-FgTad3-Amel editing enzyme system, an editing tool, and an editing method. In the present disclosure, the system is a ternary complex composed of three genes (proteins), FgTAD2, FgTAD3, and AME1, and can catalyze A-to-I editing on mRNAs. Extensive A-to-I mRNA editing can be detected by expressing the AME1 gene in vegetative stage of Fusarium graminearum. Transforming the FgTad2-FgTad3-Ame1 editing enzyme system into Saccharomyces cerevisiae, Escherichia coli, and human cells to allow expression can produce A-to-I mRNA editing. This indicates that a Fusarium graminearum-derived A-to-I mRNA editing system is active and broadly adaptable, and has a great potential to be developed as a gene editing tool in different organisms.

  • Publication number: 20250086355
    Abstract: A train crash energy management (CEM) optimization method based on machine learning is provided. The method includes: establishing a finite element model that is for an eight-marshalling train crash and considers a train energy absorption subsystem and a wheel-rail rolling contact behavior; establishing a machine learning database for train crash energy absorption; constructing a machine learning prediction model for the train crash energy absorption; and performing multi-objective optimization on CEM of a train based on machine learning.

  • Publication number: 20240232475
    Abstract: The present disclosure discloses a modeling method for a rail vehicle collision finite element dummy and simulation system, and relates to the technical field of rail transit. The method according to the present disclosure includes the following steps: S1: establishing a dummy finite element model with a characteristic parameter of a target human body; S2: establishing a multi-marshaling train collision finite element model considering a vehicle body collision energy-absorbing structure and wheel-rail rolling contact behavior; S3: establishing a rigid-flexible coupling model inside a rail vehicle; and S4: establishing a passive safety simulation and analysis system integrating the rail vehicle and the dummy finite element model.

  • Publication number: 20230281352
    Abstract: The present application provides a simulation method for equivalent fatigue damage of wheel-rail steel, and relates to the study of wheel-rail relationship of rail transportation. After obtaining the train load spectrum when the target train serves for the preset mileage, the wheel-rail systematic 3D model corresponding to the target train is assigned to simulate the load according to the train load spectrum to obtain the stress spectrum of the dangerous part of the rim, and determine the target stress and stress application frequency corresponding to the expected simulated mileage according to the stress spectrum of the dangerous part of the rim. Then, the driving fatigue test machine carries out fatigue tests on the wheel-rail steel fatigue sample of the target train according to the target stress and stress application frequency, and obtains the equivalent fatigue damage data of the wheel-rail steel at the expected simulated mileage of the target train.

  • Publication number: 20220401825
    Abstract: Provided are an alarm method and apparatus for a tabletop game, an electronic device and a storage medium. The method includes that: at least one frame of game tabletop image collected in a prop operation stage of a game is acquired; for each frame, a placement position of a preset identity object in the game tabletop image is detected, a tabletop of the game including a placement region corresponding to each game party, and the preset identity object being configured to identify a first game party allowed to operate a game prop; a second game party corresponding to the placement position of the preset identity object is determined according to the placement region corresponding to each game party; and in a case where the first game party is inconsistent with the second game party, alarm information for characterizing a placement error of the preset identity object is output.
