The disclosure relates to the technical field of charging, and in particular, relates to a charging apparatus. A charging apparatus includes a support unit; a charging bow lifted and assembled on the support unit; a retractable mechanism, where the retractable mechanism retracts a cable, and a free end of the cable pulls the charging bow up and down; and a straining member assembled on a mounting point of the cable near the free end. After the charging bow is docked with a pantograph, the retractable mechanism continues to release the cable to relax the cable. Under the action of the straining member, the cable between the mounting point and the retractable mechanism is in a strained state, and the cable between the mounting point and the charging bow forms a cable slack section.

A primer set ofbased on specific hyperbranched rolling circle amplification (HRCA) isothermal amplification includes: Lock and Key series primers for a recognition stage, and Loop and Link primers for an amplification stage. Using the primer set for an HRCA reaction enables rapid and sensitive detection with reliable and stable results. A method for detecting theincludes: (1) constructing a 'lock' structure with recognition function; (2) performing magnetic selection and recognition; (3) conducting HRCA amplification; and (4) identifying a fluorescent signal to determine a positive or negative result determination. The method adopts the “lock” structure to design multiple conserved fragments of theinsertion sequence 6110 (IS6110) as target genes to jointly trigger the HRCA reaction, thereby enhancing the accuracy of the method.

Disclosed is a fully convolutional genetic neural network method for segmentation of infant brain record images. First, infant brain record image data is input and preprocessed, and genetic coding initialization is performed for parameters according to the length of a DMPGA-FCN network weight. Then, m individuals are randomly grouped into genetic native subpopulations and corresponding twin subpopulations are derived, where respective crossover probability and mutation probability pm of all the subpopulations are determined from disjoint intervals; and an optimal initialization value fa is searched for by using a genetic operator. Afterwards, fa is used as a forward propagation calculation parameter and a weighting operation is performed on the feature address featuremap. Finally, a pixel-by-pixel cross-entropy loss is calculated between predicted infant brain record images and standard segmented images to reversely update the weights, thus finally obtaining optimal weights of a network model for segmentation of the infant brain record images.
