Abstract: Systems, methods, and non-transitory computer-readable media can stream a live video stream from a content provider. A portion of the live video stream can be buffered in a content buffer. The portion of the live video stream accumulated in the content buffer can be monitored during playback of the live stream. A latency action can be determined based on the monitoring of the portion of the live video stream. The latency action can adaptively adjust the playback of the live video stream. The playback of the live video stream can be caused to be adjusted adaptively according to the latency action.

Abstract: The present invention discloses a method for estimating soil organic carbon in karst area, including: step 1, establishing a soil organic carbon estimation model for the karst area; step 2, revising a soil depth; step 3, subtracting an exposure rate of bedrock for different types of soil and positive and negative terrains; step 4, revising a soil organic carbon density estimation formula for different types of soil and positive and negative terrains; and step 5, revising a soil organic carbon storage estimation method. This invention has solved the problem of overestimating soil organic carbon pool by existing methods, has improved the calculation accuracy, and has promoted the research process of soil carbon cycle in karst area.

Abstract: An online advertising system stores advertisement placements and an advertisement campaign that is associated with the advertisement placements. The advertisement campaign includes a plurality of advertisement sets that each are associated with a respective set of selection rules. A request for an advertisement is received from a publishing system, the request specifying an advertisement placement and including advertisement selection information. The advertisement campaign is identified based in part on the advertisement placement, and an advertisement set is selected based in part on the selection information and a set of selection rules associated with the advertisement set. A creative group within the selected advertisement set is selected based on the selection rules, and an advertisement within the selected created group is selected using portions of the advertisement selection information and asset parameters associated with the advertisements in the selected creative group.

Abstract: Multiple search indexes can be served from a common set of resources. Instead of requiring a processor to be dedicated to serving a single search index, a processor can provide responsive documents for search queries that are based on different ranking algorithms and/or different sets of documents.
