Abstract: According to implementations of this disclosure, a method, an apparatus, a device and a medium for managing an element in an electronic book are provided. In one method, a block node is generated based on a paragraph in the electronic book, the paragraph comprises at least one element, and the at least one element is comprised at least one of a text element or a non-text element. A text sub node of the block node is generated based on a text element included in the paragraph, and the text element includes at least one character. A non-text sub node of the block node is generated based on a non-text element included in the paragraph. A hierarchical structure for identifying the at least one element is generated based on the block node, the text sub node, and the non-text sub node.

Abstract: A virtual reality interaction method and apparatus, a device and a storage medium are provided. The method includes: displaying, on a terminal, a real-time captured real-world scene image; wherein the real-world scene image includes a virtual model; extending a scene edge of the virtual model towards a screen edge of the terminal; switching a scene image displayed on the terminal from the real-world scene to a virtual scene in response to detecting that a viewpoint of the terminal crosses a plane where the scene edge of the virtual model located,; and obtaining an interactive instruction for the virtual scene and displaying an interactive effect corresponding to the interactive instruction.

Abstract: The embodiments of the present disclosure provide an image processing method and apparatus, a device, a medium and a product. The method includes: obtaining at least two original images; displaying the at least two original images on a current screen in a preset manner, and sending the two original images to a server, such that the server performs fusion processing on the at least two original image s; and receiving a first target image returned by the server, and displaying the first target image on the current screen, where the first target image is an image obtained after the server has performed the fusion processing on the at least two original images.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating video anchors for a video. In one aspect, a method includes obtaining key moment identifiers for a video, where each key moment identifier includes a time index value specifying a playback time in the video, and is indicative subject matter of the video that has been determined to meet one or more interest criteria that define salient topics within the video. For each key moment identifier, a video anchor is generated, where each video anchor indicates a playback time for the video, and may include an image of a frame that occurs near the playback time. Upon a selection of the video anchor by the user, an instruction in the video anchor causes a video player to begin playback of the video at the playback time specified by the video anchor.

Abstract: The present invention provides a novel EZH2 inhibitor compound represented by formula (I) and a use of the inhibitor compound in preventing or treating a disease mediated by EZH2.

Abstract: The present invention relates to a macro plastic and micro plastic detection method based on RGB and hyperspectral image fusion, which includes the following steps: obtaining macro plastics and micro plastics; mixing with solid wastes to obtain a solid-phase substrate; pretreating the obtained solid-phase substrate to obtain a material; drying to remove part of moisture and coating on a quartz window sheet, drying until the moisture is completely removed, and flattening by using another quartz window sheet to obtain a material to be detected; obtaining an RGB image and a hyperspectral image of the material to be detected respectively by using a high-resolution color image scanner and a hyperspectral camera; fusing the obtained RGB image and hyperspectral image; and automatically classifying and identifying the macro plastics and the micro plastics by using a supervised classification model.

Abstract: In one aspect, a method includes obtaining videos and for each video: obtaining a set of anchors for the video, each anchor beginning at the playback time and including anchor text; identifying, from text generated from audio of the video, a set of entities specified in the text, wherein each entity in the set of entities is associated with a times stamp at which the entity is mentioned; determining, by a language model and from the text generated from the audio of the video, an importance value for each entity; for a subset of the videos, receiving rater data that describes, for each anchor, the accuracy of the anchor text in describing subject matter of the video; and training, using the human rater data, the importance values, the text, and the set of entities, an anchor model that predicts an entity label for an anchor for a video.

Abstract: The present application provides a composition for organ-specific delivery of nucleic acids, which comprises a guided on-target lipid delivery lipid; further, the composition may comprise a helper lipid; still further, the composition may comprise a cationic lipid. The guided on-target lipid delivery lipid may be selected from one or more of an ionizable anionic steroid and/or an ionizable anionic polymer conjugated lipid; the helper lipid is optionally one or more of a phospholipid, a steroid, a polymer conjugated lipid, and a modifiable lipid; and the cationic lipid may be selected from one or more of a permanently cationic lipid and/or an ionizable cationic lipid. The delivery composition is capable of specifically delivering a prophylactic/therapeutic agent, particularly a nucleic acid component, to a target organ.
