A quantitative diagnosis method for freshwater fish diseases based on OpenCV weak supervision and ResNet50-ADCA dual-branch model is proposed. The method consists of the following steps: (1) Image acquisition and preprocessing: Based on the publicly available freshwater fish disease dataset, a balanced Salmon++ dataset is constructed by combining samples collected from aquaculture sites; (2) Weakly supervised lesion segmentation and labeling: (2.1) HSV color space targeted segmentation; (2.2) Iterative optimization mechanism; (2.3) Disease grading standard; (3) ResNet50-ADCA dual-branch model construction: (3.1) Backbone network and transfer learning; (3.2) SEA channel attention embedding; (3.3) Dual-branch multi-task output layer design; (3.4) Classification branch; (3.5) Grading branch; (3.6) Loss function design; (4) Model training and optimization. This invention balances labeling efficiency, diagnostic accuracy, and quantitative grading capability, and can effectively solve the problems of high labeling cost, poor adaptability to complex environments, lack of quantitative evaluation function, and imbalance between accuracy and speed in the existing technology.

The invention relates to a molecular marker for noninvasive evaluation of severity of esophageal and gastric varicosity, and belongs to the technical field of molecular biology. The invention provides a molecular marker for noninvasive evaluation of severity of esophageal and gastric varicosity. The molecular marker comprises gender, platelet count, spleen thickness, spleen major diameter and spleen hardness. The molecular marker is used for evaluating the severity of esophageal varicose veins, is noninvasive, has higher detection accuracy (AUC is greater than 0.9), can more accurately and directly reflect the severity of esophageal varicose veins of liver cirrhosis patients, is more accurate in grading, and can be used for detecting the severity of esophageal varicose veins of liver cirrhosis patients. And the risk of the liver cirrhosis patient suffering from esophageal and gastric varicose veins can be accurately divided into low, medium and high levels. Moreover, when the molecular marker is used for evaluating the severity of esophageal and gastric varicose veins, the molecular marker is easy to realize clinically, economical and practical, is easy to accept by patients, can obtain a better clinical effect, and has a great application prospect.

The utility model discloses an ore raw material vibration washing screen for calcium powder production belongs to calcium powder production equipment technical field, including processing box, the one side of processing box is provided with the mounting slot, the inside symmetry of processing box is provided with a plurality of limit slot, and the inside between a plurality of limit slot is provided with screening subassembly, the top fixed connection of processing box has the mounting bracket, the top fixed connection of mounting bracket has the washing subassembly, the upper surface of mounting bracket is provided with movable slot, the inside of movable slot is provided with adjusting assembly, through the screen hole aperture of multilayer screen frame 202 in screening subassembly gradually reduces from top to bottom along the vertical direction, thereby through the gradual change of screen frame aperture, thereby can accurate grading different particle size ore, promotes screening efficiency and accuracy, provides high quality raw material for subsequent calcium powder production, solves the problem that the single layer screen structure in the existing equipment, thereby cannot fine grading, makes different particle size ore separation not thoroughly, and further influence the follow -up production problem.

The utility model discloses a kind of dispersing cooling machine for asphalt mixture, belong to asphalt recycling technical field, the equipment includes rack, is equipped with crushing device, dispersing device, cleaning assembly and cooling assembly on rack.Crushing device is broken material by two reverse rotation's rotary roller and staggered crushing tooth disc, cooperate limiting tooth plate and clean adhering asphalt on tooth disc;Dispersing device is divided chamber by filter screen, realizes classification screening when conveying roller conveys material, and plug plate device guides different granularity material and discharges from corresponding discharge port;Cleaning assembly is driven by electric push rod to swing along guide rail by cleaning scraper, cooperate bristle and clean screen filter hole;Cooling assembly is sprayed by water pump to the cooling water of water storage tank body through spraying channel, realizes material cooling and screen flushing cooperation.The utility model solves the problem of existing equipment crushing adhesion, low screening precision, screen easy to block, low cooling efficiency, can improve processing efficiency and continuity, reduce energy consumption and maintenance cost.

The utility model relates to biological organic fertilizer production technical field discloses anti -blocking type biological organic fertilizer drum classifying screen, including the casing, casing inner wall left and right sides all are fixedly connected with the baffle, casing inner wall left and right sides all are rotatively connected with the rotating rod, casing inner wall rotatively connected with the drum screen, the drum screen is connected with the rotating rod through the rotating subassembly, the right end of casing outer wall rear side is installed with the motor, motor drive end is connected with right side bottom rotating rod, the drum screen inner wall rear end is connected with the drum brush through the transmission assembly, the drum brush front end is rotatively connected with casing inner wall front side. In the utility model, through the linkage structure inside drum screen realizes the synchronous rotation of drum brush and drum screen, carries out real -time cleaning to the screen hole. The clogging under the brush falls back to the material and is screened again, avoids the cumbersome of traditional drum screen and improves production efficiency obviously.
