Abstract: A fish school detection method and a system thereof, an electronic device and a storage medium are provided, the method includes inputting a to-be-detected fish school image into a fish school detection model; the fish school detection model including a feature extraction layer, a feature fusion layer and a feature recognition layer; extracting feature information of the to-be-detected fish school image based on the feature extraction layer, and determining a fish school feature map and an attention feature map based on an attention mechanism; fusing the fish school feature map and the attention feature map based on the feature fusion layer to determine a target fusion feature map; and determining a target fish school detection result based on the feature recognition layer and the target fusion feature map. Interference from environmental factors on detection results is eliminated, so as to effectively improve accuracy of the fish detection.

Abstract: The present application discloses a cerebral perfusion state classification apparatus and method, a device, and a storage medium. The method includes: acquiring, by a transceiving module, cervical blood flow data from an ultrasound data collecting device; determining, by a processor, cerebral perfusion data corresponding to the cervical blood flow data based on the cervical blood flow data and a mapping relationship between the cervical blood flow data and the cerebral perfusion data, and classifying cerebral perfusion states of a plurality of brain regions based on blood perfusion characteristics of the plurality of brain regions in the cerebral perfusion data.

Abstract: An embodiment of the present invention provides a plane scroll spring. A torque provided by a working section of a reed of the plane scroll spring is gradually reduced from an outer ring toward an inner ring of the plane scroll spring. The working section includes a first length section and a second length section connected to an inner end of the first length section. In the first length section, the torque decreases by a first decrement value per unit length from the outer ring toward the inner ring. In the second length section, the torque decreases by a second decrement value per unit length from the outer ring toward the inner ring. The first decrement value is less than the second decrement value.

Abstract: A method for forming gold nanowires on a substrate is provided. The method includes a) attaching noble metal nanoparticles onto the substrate; and b) contacting the noble metal nanoparticles with an aqueous solution comprising a ligand, gold ions and a reducing agent, wherein the ligand is an organic compound having a thiol group. Gold nanowires formed by a method according to the method, and an electronic device comprising the gold nanowires are also provided.
