Abstract: A micropore ultrasonic disintegration device for sludge cell disintegration is provided, including an ultrasonic treatment chamber. The ultrasonic treatment chamber is internally provided with a first stirring mechanism which includes a reciprocating lead screw. One end of the reciprocating lead screw penetrates through a top surface of the ultrasonic treatment chamber, and the other end of the reciprocating lead screw is provided with stirring blades. The ultrasonic treatment chamber is internally provided with a second stirring mechanism, a side wall of the ultrasonic treatment chamber is provided with a first opening, and an inner wall of the ultrasonic treatment chamber is provided with a switch mechanism. The switch mechanism includes a baffle plate and a second connecting rod. The side wall of the ultrasonic treatment chamber is provided with an ultrasonic generator, and the top surface of the ultrasonic treatment chamber is provided with a liquid inlet pipe.

Abstract: Technologies for digital content distribution include creating a data set that includes a plurality of entity data records each comprising a plurality of attribute values. By applying a first data security technique to the data set, a first query term and a matching subset of the plurality of entity data records are determined. A second data security technique is applied to the matching subset. When output of the second data security technique satisfies a first noisy threshold, the first query term is added to a set of query terms. A third data security technique is applied to the matching subset. When output of the third data security technique satisfies a second noisy threshold, the set of query terms is expanded to include a second query term. The set of query terms is used to perform the digital content distribution.

Abstract: Machine learning techniques to optimize user interface template selection are provided. In one technique, a first set of feature values pertaining to a first entity is identified. Multiple sets of feature values are also identified, each set of feature values pertaining to a different user interface (UI) template for rendering content items on a computer screen. For each set of feature values of the multiple sets, the set of feature values and the first set of feature values are inserted into a machine-learned model to generate a score, which is added to a set of scores, which set of scores is initially empty. Based on the set of scores, a particular UI template is selected for a content item. The content item is transmitted over a computer network to be presented on a screen of a computing device of the first entity according to the particular UI template.
