Abstract: A circadian rhythm (CR) oscillator is obtained for a person based at least in part on a bathyphase time. A fatigue value is calculated for the person. Calculating the fatigue value includes, in response to determining that the person is in sleep, subtracting a sleep recovery unit from the fatigue value in a time unit; and accumulating, in a first time range of the sleep, a total sleep inertia by an inertia in sleep in the time unit. The sleep recovery unit is calculated based on the CR oscillator and a recovery debt In response to determining that the person is performing an activity and determining that the fatigue value is above a threshold, the person is notified to recover to decrease the fatigue value below the threshold prior to performing the activity.

Abstract: A method and device for in-situ enriching Anammox bacteria by conventional activated sludge, which belongs to a biological wastewater treatment technology. The device comprises a raw water tank, an anammox reactor and a water outlet tank.

Abstract: A multiplexed display panel and device and a driving method for the multiplexed display panel are provided. At the moment when a switching switch is turned on, a potential of a fanout line corresponding to a data line connected to sub-pixels, into which an data signal is input, is adjusted to the same level as a potential of the data line as much as possible, and a potential difference between each fanout line and the corresponding data line is relatively small at the moment when the switching switch is turned on, so that an instantaneous current at this moment is greatly reduced without causing relatively large jump of the potential of the data line, a common electrode and back-plated indium tin oxide (ITO) greatly fluctuate, and then the surface noise generated by the display panel is turned on is greatly reduced.

The circuit includes a plurality of optical image stabilizers OIS, a gyroscope, and a control circuit, where an input terminal of the control circuit is connected to a power terminal, an output terminal of the control circuit is connected to the plurality of OISs separately, and the plurality of OISs are all connected to the gyroscope; and the control circuit controls one of the plurality of OISs to conductively connect to the gyroscope and establish a communication connection.

Abstract: A testing device for study of a magnetized plasma artillery and gunpowder, comprising a pedestal, wherein a top end of the pedestal is provided with a sliding slot for mounting a buffer device, which penetrates through an upper part of the pedestal along a front-rear direction. The sliding slot for mounting the buffer device is internally provided with a buffering slider, which can slide back and forth along the sliding slot for mounting the buffer device. A top end of the buffering slider is provided with a gunpowder combustion chamber fixing groove, which penetrates through an upper part of the buffering slider along the front-rear direction. The gunpowder combustion chamber fixing groove is internally provided with a gunpowder combustion chamber, and an upper part of the gunpowder combustion chamber is provided with a positioning ferrule for fixing the gunpowder combustion chamber.

Abstract: An operating method of a clock-calendar and a portable electronic device using the same are provided, where a touch screen display of the portable electronic device displays the clock-calendar with a clock pattern. In the method, a gesture on the touch screen display corresponding to the clock-calendar is detected and analyzed, where the gesture includes a gesture starting point and a gesture finishing point on the touch screen display. After the gesture is analyzed, the clock-calendar is operated according to the gesture.
