Abstract: A control circuit, a drive device, and a display. The control circuit includes: a control unit and a detection unit. The detection unit is connected with a plurality of output voltage feedback terminals of a drive chip, and the detection unit is connected with the control unit. The detection unit is configured for providing a first voltage to the control unit when a voltage of at least one output voltage feedback terminal in the plurality of output voltage feedback terminals is detected, the first voltage being greater than a second voltage received by the control unit. The control unit is configured for controlling the drive chip to restart when the first voltage is greater than the second voltage.

Abstract: The present disclosure provides use of fructose in preparing a drug for treating a cerebral ischemic stroke, and relates to the technical field of biomedicine. In the present disclosure, an ischemic injury cell model and an ischemic injury animal model are established, and fructose treatment is conducted on the injury models; and it is found that the fructose can regulate energy metabolism and redox metabolism of neurons, and reduce an ischemic injury of model cells and model animals. Specifically, the present disclosure includes: reducing a neuronal mortality after the ischemic injury, reducing an area of cerebral infarction in animals with the ischemic injury, and improving neurobehavioral characteristics of the animals.

Abstract: The present disclosure provides a method and apparatus for extracting a video preview, a device and a computer storage medium. The method comprises: inputting a video into a video classification model obtained by pre-training; obtaining weights of respective video frames output by an attention module in the video classification model; extracting continuous N video frames whose total weight value satisfies a preset requirement, as the video preview of the target video, N being a preset positive integer. It is possible to, in the manner provided by the present disclosure, automatically extract continuous video frames from the video as the video preview, without requiring manual clipping, and with manpower costs being reduced.

Abstract: The present disclosure provides a video displaying method and apparatus, a device and a computer storage medium, wherein the method comprises: positioning a target video; displaying a video preview of the target video, the video preview being a video segment extracted from the target video. This displaying manner exhibits a stronger capability of expressing the video content. The user can better know whether the video is the desired content. The present disclosure may reduce a probability of the user missing desired video resources and reduce a probability that the user finds that the video content does not meet an expectation after he views the video content, thereby helping the user to conveniently and effectively view the desired video resources.
