Abstract: A control method and apparatus for displaying multimedia content, an electronic device, and a medium. The method includes: displaying a first-type multimedia content on a first content display layer of a first-type multimedia content display interface, the first-type multimedia content display interface including: a first user interaction layer and the first content display layer, the first user interaction layer being superimposed and displayed on the first content display layer; and receiving a first swiping operation inputted by a user on the user interaction layer, and exiting the first-type multimedia content display interface. That is, a swiping operation triggers to exit the first-type multimedia content display interface, as the swiping operation is significantly different from a click operation, the user is provided with a multimedia content display control method that is more consistent with the user's operation habit, improving the user experience.

The two glass cover plates are respectively disposed at the lower optical detection through hole and the upper optical detection through hole. The foam board is provided with a foaming structure capable of generating bubbles and a surfactant coated on the foam board, the foam board is disposed at the gas flow channel.

Abstract: Described herein is a method for producing photochromic silicone hydrogel contact lenses in a relatively efficient and consistent manner from a polymerizable composition under a controlled thermal curing scheme. The main polymerizable components in the polymerizable composition are a high radical-reactive hydrophilic (meth)acrylamido monomer, a high radical-reactive siloxane-containing (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker(s) free of low-reactive ethylenically unsaturated group as the main crosslinker. The thermal free radical initiator having a 10 hour half-life temperature (T10h?) of from about 50° C. to about 90° C. The controlled thermal curing scheme includes maintaining a first curing temperature of from about (T10h??20)° C. to about T10h?° C. for a first curing time and maintaining a second curing temperature of from about (T10h?+10)° C. to about (T10h?+35)° C. for a second curing time.

Abstract: The invention is generally related to a soft hydrogel ocular insert that is composed of at least one hydrogel material in fully hydrated state and can be comfortable for wearing. The hydrogel material comprises polymer chains, which are derived from at least one arylborono-containing hydrophilic copolymer and at least one mucoadhesive polymer, and cyclic boronic ester crosslinks for crosslinking those mucoadhesive polymer chains and arylborono-containing hydrophilic copolymer chains to form a 3-dimensional polymer network. Those cyclic boronic ester crosslinks can be hydrolyzed slowly in the tear of the eyes of a patient, resulting in the disintegration (dissolution) of the 3-dimensional polymer network and thereby providing mucoadhesisve polymers and optionally drugs impregnated in the hydrogel ocular insert in a controlled manner.

Abstract: Techniques provided comprises obtaining a content set to be screened, wherein the content set comprises a plurality of to-be-screened contents, wherein each to-be-screened content is associated with identification information, at least one tag indicative of at least one category, and a score; computing a distribution quota value of each category indicated by a corresponding tag and associated with the plurality of to-be-screened contents based on the at least one category and a weight value corresponding to the at least one category; computing a target distribution quota value of the tag of each category based on the distribution quota value of each category and a preset tag distribution quota adjustment function; and sequentially selecting target contents from the content set based on the target distribution quota value of each category and the weight value corresponding to the at least one category associated with each to-be-screened content.

Abstract: m This application provides techniques of improving video recommendation. The techniques comprise temporarily pre-adding a first video to a recommendation video sequence; capturing a sub-sequence including the first video; modifying an initial recommendation score of the first video based on a position sequence number of the first video in the sub-sequence and a position sequence number of another video in the sub-sequence to obtain a modified recommendation score of the first video, the another video sharing a target attribute with the first video; and adding a video with a highest modified recommendation score to the recommendation video sequence.

Abstract: An retinal vessel image enhancement method comprises: constructing a blood vascular dictionary; applying Frangi-based filtering to retinal vessel images, deciding blood vessels in a second image sub-block belong to wide or thin vessels by directional filtering, and setting residual error weight and residual error threshold of a vascular region; calculating inner products between the second image sub-block and each first image sub-block, selecting a first image sub-block with maximum inner product, and calculating its corresponding sparse coefficient; calculating residual error image, and calculating the residual error of the vascular region according to the residual error weight of the vascular region, when the residual error is greater than the residual error threshold, the residual error image is set as a second image sub-block, repeating and calculating residual error; reconstructing the second image sub-block according to the sparse coefficient, then restructuring each reconstructed second image sub-block
