Abstract: The present disclosure provides a system and methods for providing responses to user provided questions that are grounded in the user's browsing history and enables searching of the history for resources previously viewed based on the content of the resources. In one example embodiment, a portion of a query is received. A query suggestion relevant to the portion of the query is obtained. A resource from a history repository relevant to the portion of the query is identified by obtaining a semantic representation of the portion of the query, and identifying a semantic representation of content associated with the resource from the history repository. The semantic representation of the content includes a similarity score with the semantic representation of the query that satisfies a threshold. A resource suggestion is generated for the resource. The query suggestion and the resource suggestion is provided as selectable query completions.

Abstract: An application may generate tab information about tabs opened on a user device. An application may identify a tab group from the tabs, the tab group including at least two tabs determined to be related based on the tab information. An application may generate a label for the tab group based on at least a portion of the tab information. An application may modify a tab strip to include the label and the tab group.

Abstract: Provided are an electrokinetic device and method for in-situ leaching of uranium. The electrokinetic device for in-situ leaching of uranium includes an injection well, a pumping well, a positive electrode, a negative electrode, leaching solution, and a direct current power supply. Uranium ore is provided between the injection well and the pumping well, the negative electrode is arranged in the injection well, and the positive electrode is arranged in the pumping well. The leaching solution is injected from the injection well, flows through the uranium ore, and then is pumped from the pumping well for uranium extraction. The direct current power supply is respectively connected to the positive electrode and the negative electrode, and is configured to apply direct current between the positive electrode and the negative electrode to promote the pooling of uranium-carrying ions towards the pumping well.
