Provided is a display substrate. A data writing circuit included in each pixel circuit is coupled to a first scanning line, a switching control line, a data signal line, and a drive circuit. The data writing circuit transmits, under the control of the first scanning line and the switching control line, a data signal provided by the data signal line to the drive circuit, such that the drive circuit drives the coupled light-emitting element to emit light. In the same pixel circuit group, each pixel circuit subgroup is coupled to a different switching control line, and the plurality of coupled data signal lines are coupled to the same data line to receive the data signals from the data line. Thus, each pixel circuit, under the control of the switching control line coupled thereto, receives the data signal provided by the data line for the data signal line coupled thereto.

A method and an apparatus for outputting information are provided. A specific embodiment of the method includes: determining an entity characterizing a target video from a pre-created knowledge graph; acquiring authority owner information for characterizing an authority owner of the target video from attribute information of the entity; determining whether the authority owner is a target authority owner or not based on the authority owner information; and in response to determining that the authority owner is a target authority owner, determining at least one entity associated with the authority owner information from entities for characterizing videos in the knowledge graph, and generating and outputting related information of each entity in the at least one entity. According to the embodiment, based on the authority owner information, entities associated with the authority owner information can be accurately obtained, and the pertinence of information shown for the user can be improved.

Method and apparatus for outputting information

Provided is a method for processing information associated with video. The method includes: storing an association relationship between identification information of a first video and identification information of a second video, the two videos including a same video content segment; receiving a video query request message; in a case where the video query request message includes the identification information of the first video, acquiring and returning the identification information of the second video associated with the identification information of the first video; or in a case where the video query request message includes the identification information of the second video, acquiring and returning the identification information of the first video associated with the identification information of the second video. Further provided are an apparatus for processing information associated with video, a method and an apparatus for querying information associated with video, an electronic device, and a storage medium.

A manganese dioxide nanowire @ multidimensional mesoporous metal-organic framework adsorbent and application method thereof for removing heavy metals from water. A multidimensional mesoporous metal-organic framework material is prepared from metal ions and organic ligands by means of a self-assembly reaction; a manganese dioxide nanowire is prepared from manganese salt and thiosulfate by means of reaction in a reaction kettle. The adsorbent possesses not only the characteristics of a multidimensional mesoporous metal-organic framework material, such as reticulated pore adaptation, a large specific surface area, and abundant reaction sites, but also the oxidative and catalytic properties of manganese dioxide nanowire.
