Abstract: Disclosed is a method for optimization design of an artificial reef structure. The method includes: arranging an artificial reef model to be tested on a test platform, testing a flow field to obtain flow field data and a pull force of an artificial reef, analyzing the flow field data to obtain a flow velocity reference point, and carrying out optimization analysis in combination with the flow field data and the pull force.

Abstract: The present invention relates to the technical field of computers, and more particularly, to a method for generating training data based on immunohistochemistry, and a storage device. The method for generating the training data based on immunohistochemistry includes the following steps: performing immunohistochemical staining on a target object through different antibodies; labeling the target object according to staining results; and generating training data according to labeling results. According to the method, a pathologist can label a tissue or cell of interest rapidly and conveniently without performing labeling through H&E slicing in combination with histomorphology. In addition, since this tissue or cell is labeled based on an immunohistochemistry technology of a gold standard, this labeling is more accurate compared with manual labeling performed through H&E slicing in combination with histomorphology.

Abstract: The present invention relates to an aqueous copolymer dispersion comprising an emulsion copolymer and two hydrophobic aromatic ketones, wherein the aromatic ketones are, based on the dry weight of the copolymer, from 0.1 to 3 wt % benzophenone and from 0.1 to 4 wt % a benzophenone derivative; wherein the dispersion comprises 0 or less than 0.1 wt % hydrophilic aromatic ketone. The copolymer dispersion is suitable for preparation of aqueous coating compositions which yields a relatively hard surface to provide not only short term but also long term dirt pick up resistance effects, after exposure to ultraviolet radiation.
