Abstract: The present application discloses a deep learning method and system for spectrum sharing of partially overlapping channels. The method comprises the following steps: in response to a received user transmission request, inputting, by a base station, channel state information CSI of a plurality of historical time slices into a trained channel prediction convolutional neural network model and outputting predicted channel state information CSI of a next time slice; and inputting the channel state information CSI of the next time slice into a reinforcement learning model and obtaining a channel allocation strategy of each user equipment in a collision domain of the base station so as to realize a maximum throughput of simultaneous communication of each user equipment, wherein the reinforcement learning model is obtained by training by taking bandwidth efficiency performance as a reward. The present application is high in universality, bandwidth utilization rate and throughput for communication networks.

Abstract: The present disclosure relates to a liquid flow charging device for a flow cell and a flow cell comprising the liquid flow charging device. The liquid flow charging device comprises a first electrode and a second electrode. The first electrode is electrically connected to a liquid flow flowing through a flow channel assembly of the flow cell. The second electrode is located at a predetermined position on a radially outer side of the liquid flow and has a cylindrical inner peripheral surface surrounding the liquid flow. The liquid flow charging device has improved charging efficiency, stable charging performance, and enhanced safety.

Abstract: A method and apparatus for determining a hot event are provided. The method includes: acquiring an event list within a predetermined time period, an event in the event list including: a time period, a keyword list, and a viewpoint list; determining a theoretical heat value of the event in the event list at a current moment based on an initial heat value of the event in the event list and a current environment heat value; calculating a difference between the current heat value and the theoretical heat value for the event in the event list; and determining an event having the difference greater than a predetermined threshold as a hot event.

Abstract: Embodiments are directed to methods and systems for defining customizable data services through dynamic configuration of a dashboard using data feeds, analytics, and visual artifacts. A customizable dashboard is built using a basic framework, design time configuration, instantiation time binding, and runtime ad hoc data input. The customizable data service binds business logic in a data query service with a visual tile template that provides specific parameters for visualizations and/or queries. The visual tile templates are pluggable visual on multiple dashboard pages.
