Abstract: Computer-readable media, methods, and systems are disclosed for automatic generation of dynamic application trace logs associated with a running application. A log viewer presents application log entries associated with an application execution log having been generated in connection with a previous execution of the running application. The application execution log is analyzed to identify application execution log context descriptors. The application execution log context descriptors are extracted from the application execution log. The application execution log context descriptors are transmitted to the running application. Matching templates that match each of the one or more application execution log context descriptors are received from the running application. The tracing templates that have an associated context relevance score are received from the running application.

Abstract: A system for increasing the extraction of an active ingredient includes a vacuum quick-dissolving tank, a mixer, a solid-liquid separator, and a homogenizer. The vacuum quick-dissolving tank receives a sample. The mixer is connected to the vacuum quick-dissolving tank, and provides an aqueous solvent to be mixed with the sample. Heating, cooling, stirring, and vacuuming in the vacuum quick-dissolving tank make the sample dissolve and emulsify repeatedly between the vacuum quick-dissolving tank and the mixer to produce a mixture, which is output by the vacuum quick-dissolving tank. The solid-liquid separator receives the mixture output from the vacuum quick-dissolving tank for solid-liquid separation, and outputs an isolated sample liquid. The homogenizer receives the sample liquid output from the solid-liquid separator, performs high-pressure homogenization to obtain an extract liquid containing an active ingredient, and outputs the extract liquid.

Abstract: An electronic device such as a head-mounted device may present extended reality content such as a representation of a three-dimensional environment. The representation of the three-dimensional environment may be changed between different viewing modes having different immersion levels in response to user input. The three-dimensional environment may represent a multiuser communication session. A multiuser communication session may be saved and subsequently viewed as a replay. There may be an interactive virtual object within the replay of the multiuser communication session. The pose of the interactive virtual object may be manipulated by a user while the replay is paused. Some multiuser communication sessions may be hierarchical multiuser communication sessions with a presenter and audience members. The presenter and audience members may receive generalized feedback based on the audience members during the presentation.

Abstract: A recognition method includes the following steps. A text is analyzed by a language recognition network to generate an entity feature, a relation feature and an overall feature. An input image is analyzed by an object detection network to generate candidate regions. Node features, aggregated edge features and compound features are generated by an enhanced cross-modal graph attention network according to the entity feature, the relation feature, the candidate regions and the overall feature. The entity feature and the relation feature are matched to the node features and the aggregated edge features to generate the first scores. The overall feature is matched to the compound features to generate second scores. Final scores corresponding to the candidate regions are generated according to the first scores and the second scores.
