Abstract: The present disclosure provides a kit and method for constructing a long-acting depression animal model. The present disclosure adopts Bacille Calmette-Guerin (BCG) (or Mycobacterium bovis (M bovis)) and low-dose pertussis toxin (PTX) for combined induction, which greatly reduces modeling cost. A mouse model constructed by the method of the present disclosure can clearly distinguish a time interval of pathological behaviors from a time interval of depression-like behaviors and has prominent face validity and predictive validity. The method of the present disclosure is simple and convenient and does not require a large number of tedious daily operations as the depression model construction by chronic unpredictable stress, chronic restraint stress, social defeat, mother-child separation, or the like. The mouse model of the present disclosure can provide a valuable long-term intervention window for research on antidepressant therapy.

Abstract: A method for determining a charging price for an electric charging site includes receiving time tags and data obtained based on automated metering infrastructure (AMI) data for the electric charging site, and weather information for a service area of the electric charging site; clustering power consumption of the electric charging site with similar weather information and time tags; calculating a center of mass and a distribution confidence parameter for the clustered power consumption to obtain a look-up table; retrieving historical information of voltage VPCC and injection power Psite pairs that is measured at a point of common coupling (PCC) of the electric charging site; receiving weather forecast information for the service area of the electric charging site; and calculating a dynamic hosting capacity (DHC) curve and a price curve based on the center of mass and the distribution confidence parameter, the VPCC and Psite pairs, and the weather forecast information.

Abstract: A humidifying and fresh-keeping device for a refrigerator is provided, including a device container and a top cover. The container has a drawer for storing fruits and vegetables, and a containing chamber is disposed at one side of the container. A drawer-type water tank is disposed in the containing chamber, with a water storing box at one end and an ultrasonic humidifying device at the other end. A supply air box is disposed at a wind outlet of the ultrasonic humidifying device, and an atomizing air duct is distributed in the container. An inlet of the atomizing air duct corresponds to an outlet of the supply air box, and outlets of the atomizing air duct are provided in the containertop cover. As a result, the fruits and vegetables preserved in the container have an environment humidity of 90-95%, and can be kept fresh in seven days.
