Abstract: An air conditioner includes a housing having an air outlet chamber, an air treatment apparatus disposed in the housing, and an air guide mechanism movably disposed in the housing. A vent connecting the air outlet chamber with outside is formed at a sidewall of the air outlet chamber. The air treatment apparatus includes an air treatment unit and has an air inlet. The air guide mechanism is configured to connect an inner cavity of the air treatment unit with outside or isolate the inner cavity of the air treatment unit from outside. When the inner cavity of the air treatment unit is in communication with outside, air entering through the air inlet flows through the air treatment unit and into the air outlet chamber, and then flows out through the vent.

Abstract: Provided is a drug target for vitiligo. The drug target is IFN-? signaling. It also provides a method for establishing vitiligo animal model, or a vitiligo induction method in an animal, and the established vitiligo animal model. Further, provided is a method for screening candidate drugs for treating vitiligo using the said animal model.

Abstract: The present disclosure belongs to the technical field of water body treatment, and particularly relates to a method for enhancing biological denitrification based on the addition of exogenous ?-cyclodextrin. Preferably, Paracoccus denitrificans and ?-cyclodextrin are added for biological denitrification enhancement. In the present disclosure, the ?-cyclodextrin is exogenously added to a denitrifying medium to construct a denitrification system, so that the denitrification rate of microorganisms may be increased and the production of harmful denitrification intermediate products is reduced.

Abstract: An over-energy protection circuit, a residual current device, an electronic device, and a power distribution box. The protection circuit has relatively high operating reliability, and includes: a first over-energy absorption circuit, a second over-energy absorption circuit, and a residual current determining circuit. The first over-energy absorption circuit receives a first electrical signal output from a current transformer; and when a voltage value of the first electrical signal is greater than or equal to a first preset threshold, performs step-down processing on the first electrical signal to obtain a second electrical signal, and outputs the second electrical signal to the second over-energy absorption circuit; or when a voltage value of the first electrical signal is less than a first preset threshold, outputs the first electrical signal to the second over-energy absorption circuit.

Abstract: A method and system for tracking a position and orientation of a target object that moves along a two-dimensional plane, a camera to generate video frames of the target object, and a processor configured to correct perspective scaling of a current one of the video frames; estimate a current location and angle of the target object using a motion model or its previous location/angle; cut out a region of interest from the current video frame around the estimated current location; resize the region of interest to shrink its size by a predetermined ratio M (width=width/M, height=height/M) or equivalently reducing the image resolution of the region of interest by the ratio M (resolution=resolution/M); track a new location of the target object by template matching the current region of interest with a previously stored template; and either conclude the tracked target object location and angle are accurate and updating the template if a stopping criterion is reached with indication of successful tracking, or proceed

Abstract: Disclosed is a method, device and system for determining stereoscopic multimedia information. The method includes: acquiring multimedia information collected by respective multimedia collection apparatuses of two or more aerial vehicles; and, determining corresponding stereoscopic multimedia information according to the acquired multimedia information. In the present disclosure, a same object is shot by respective loaded multimedia collection apparatuses of two or more aerial vehicles at different angles. In comparison with conventionally shooting a same object by a single unmanned aerial vehicle at a same angle, more stereoscopic multimedia information may be obtained, and a user is more likely to feel the stereoscopic impression of the multimedia information when viewing the multimedia information. In this way, both the visual enjoyment of the user and the user experience are improved.
