Abstract: Systems and methods of electronic altered document detection. The system may conduct operations of a method to: retrieve image data representing an alterable document and determine a target region of interest representing a boundary of an alterable parameter associated with the alterable document. The system may conduct operations to generate a tuned region of interest by calibrating the target region of interest based on an object detection model. The tuned region of interest may include a re-dimensioned boundary of the alterable parameter of interest. The object detection model may be prior-trained based on non-standardized alterable documents. The system may conduct operations to generate, based on the tuned region of interest, a prediction value representing whether the alterable document was subject to unauthorized alteration and transmit a signal representing the prediction value for identifying alterable documents for downstream document deconstruction operations.

Abstract: The present disclosure relates to a kit for quantitative detection using a fluorescent microarray, and belongs to the technical field of protein detection. The kit of the present disclosure includes a detection plate and a detection antibody coupled with fluorescent microspheres, where the detection plate is provided with a plurality of reaction chambers; the reaction chamber is provided with an opening, and an inner bottom surface of the reaction chamber is provided with a plurality of detection sites that are arranged side by side along a length direction of the reaction chamber at an interval. The kit of the present disclosure may detect allergen-specific IgE, IgG and IgA with high sensitivity, as well as rapidly and quantitatively detect an allergen-specific antibody IgE, IgG and IgA concentration in human serum or plasma, and may screen dozens of allergens at a time.
