At the same time, a concrete cube specimen is taken out to perform the uniaxial compression test on the 10th, 20th and 30th days respectively; and using the above calculation results to evaluate the corrosion evolution process thereof without damaging the underwater concrete structure.

Abstract: A method for generating AI media item recommendations includes generating a set of soft labels for a first training dataset using a teacher AI model. The first training dataset can reflect characteristics of first one or more media items accessible via a media platform. The set of soft labels can reflect predicted values of one or more metrics associated with the first one or more media items. The method further includes training a student AI model on the first training dataset using the set of soft labels generated by the teacher AI model and a set of observed labels associated with the first one or more media items. The student AI model may be trained to predict a score reflecting a relevance of a given media item to a user acting in a current user context of the media platform.

Abstract: A biochemical test strip tube comprises a tube portion and a cover portion. The tube portion comprises a solution chamber and a test strip fixing member which has a horizontal spacing between its outer edge and an inner wall of the tube portion. When the cover portion seals off the tube portion, a top of the solution chamber communicates with a top of the test strip fixing member, and a horizontal spacing is provided between an outer edge of the test strip fixing member and an inner wall of the cover portion. Due to the horizontal spacing between the test paper fixing member and the inner wall of the tube portion, the biochemical test strip does not contact or form a wall against the inner wall of the tube portion to avoid affecting the detection effect when the biochemical test strip is provided inside the test strip fixing member.
