Abstract: Provided is a manufacturing method for graphite slider arrays in batches. In this method, a grain structures examination step is added to a process of manufacturing graphite slider arrays, and a subsequent etching step is controlled so that only one horizontal grain boundary exists inside the graphite mesas, and when cleaved, the sliders slide away on the only grain boundary. The slider arrays prepared by this method have uniform easy-slip surfaces and thickness with good consistency.

Abstract: Disclosed in the present invention is a flexible modeling method for a timing constraint of a register. Simulation ranges of input terminal transition time, clock terminal transition time, and output load capacitance of a register are determined first, simulation is performed under each combination of input terminal transition time, clock terminal transition time, and output load capacitance to obtain a timing constraint range, then setup slack and hold slack are extracted in this constraint range with a particular interval, and then simulation is performed to obtain a clock terminal-to-output terminal delay. Finally, a mutually independent timing model of the register is established by using an artificial neural network, where the clock terminal-to-output terminal delay is modeled as a function of the input terminal transition time, the clock terminal transition time, the output load capacitance, the setup slack, the hold slack, and an output terminal state.

Abstract: The present disclosure provides a heat-stress related gene ZmHsf11 and an application of the gene in regulating heat resistance of plants. The present disclosure belongs to the field of biotechnology. The present disclosure reports for the first time a heat resistance negative regulation related gene ZmHsf11 and its protein. In the present invention, it is found that the expression of ZmHsf11 gene can be induced by adverse stresses such as high temperatures. By overexpressing the gene in rice and identifying functions of the gene, it is found that a survival rate of the overexpressed rice plant under the heat treatment is significantly reduced after overexpression. By identifying functions of the ZmHsf11 mutant plant obtained in the present invention, the heat resistance of the mutant plant is significantly increased after the heat treatment.

Abstract: Disclosed is a video patrol method and apparatus. The number of alarm messages for each capture device is stored in a database. According to the number of alarm messages for each capture device, the weight corresponding to each capture device is determined. The greater the number of alarm messages for a capture device is, the greater the weight corresponding to the capture device is. The play duration corresponding to each capture device is determined according to the weights. The greater the weight corresponding to a capture device is, the longer the duration for the capture device is. The play time period for each capture device is determined according to the determined play durations. The management device controls the video wall to perform video patrol according to the determined play time period for each capture device.

Abstract: Disclosed is a video switching method, a device, and a video patrol system. The method comprises: receiving a video switching instruction to determine a display device corresponding to a to-be-played video; determining whether there is a currently played video in the determined display device; if so, determining a task identifier corresponding to the currently played video; closing the currently played video according to the task identifier; and sending the video to be played to the display device for playing. When the video played in the display device needs to be switched, the task identifier corresponding to the currently played video in the display device is determined first, and the video is closed according to the task identifier. Then, the to-be-played video is sent to the display device for playing. This shows that the currently played video is normally shutdown, thereby avoiding an unknown error caused by abnormal closing of the video.
