    Abstract: An image feature visualization method and apparatus, and an electronic device during model training, inputs the real training data with positive samples into a mapping generator to obtain fictitious training data with negative samples. The mapping generator includes a mapping module configured to learn a key feature map that distinguishes the real training data with positive samples/negative samples, and the fictitious training data with negative samples is generated based on the real training data with positive samples and the key feature map. The training data with negative samples is input into a discriminator to obtain a discrimination result. An optimizer optimizes the mapping generator and the discriminator until training is completed. During model application, a target image that is to be processed is input into the mapping generator, and the mapper in the mapping generator extracts features of the target image.

    Abstract: A multi-row ultrasonic imaging apparatus and an ultrasonic imaging instrument are disclosed. The multi-row ultrasonic imaging apparatus includes a housing, and a first ultrasonic transducer, a second ultrasonic transducer, and an adjustment mechanism that are installed in the housing. Ultrasonic waves emitted by the first ultrasonic transducer and the second ultrasonic transducer can intersect to form a confocal point. At least one of the first ultrasonic transducer and the second ultrasonic transducer is connected to the adjustment mechanism to move relative to the housing under the action of the adjustment mechanism, so as to adjust the position of the confocal point.

    Abstract: Disclosed are a process parasitism-based branch prediction method and device for serverless computing, an electronic device, and a readable storage medium. The method includes: receiving a calling request of a user for a target function; when capacity expansion is required, scheduling a container executing the target function to a new server that has not executed the target function in a preset period of time, wherein a parasitic process is pre-added to a base image of the container; triggering the parasitic process when the container is initialized on the new server, the parasitic process being used for initiating a system call, and triggering a system kernel to select a target template function according to the type of the target function and copying the target template function N times; using execution data of the copied N target template functions as training data to train a branch predictor on the new server.

    Abstract: A method for determining a protein structure using cryo-electron microscopy, including: enabling a target protein to contain a tag; enabling a resulting target containing the tag to bind a scaffold protein to form a complex between the target protein and the scaffold protein; and performing single-particle imaging using the cryo-electron microscopy to determine a structure of the target protein in complex with the scaffold protein. The scaffold protein is any one of streptavidin, avidin, or derivatives thereof. The tag is configured for selectively binding to the scaffold protein. The tag is one selected from the group consisting of: a biotin tag, comprising a biotin; a biotinylated protein or polypeptide tag, comprising a protein sequence and a biotin covalently linked to the protein sequence; a Strep-tag; and a biotinylated or strep-tagged antibody, or antibody Fab fragment, or single-chain antibody.
