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: The present disclosure provides a rotation type electric toothbrush. The electric toothbrush includes a brush handle module, a vibration module and a brush head module having a brush base, a brush cover and bristles. The brush cover and the brush base are in a detachable connection. The bristles are disposed on the brush base. The brush base includes a groove. The vibration module includes a motor and an eccentric shaft having a transmission connection with the motor. The eccentric shaft inserts into the groove. When the rotation type electric toothbrush is working, the eccentric shaft rotates eccentrically to contact a side surface of the groove, so as to drive the brush base and the brush cover to have a reciprocating rotation synchronously.

Abstract: A movement support includes a base. An air inlet is formed in the base. A drainage plate is installed on the base. A first heat dissipating flow channel communicated with the air inlet is formed in the base on one side of the drainage plate. A second heat dissipating flow channel communicated with the air inlet is formed in the base on the other side of the drainage plate. The first heat dissipating flow channel and the second heat dissipating flow channel between the drainage plate and the air inlet are communicated with each other.

Abstract: The present disclosure provides a method for automatically identifying a ring joint of a shield tunnel based on a lining structure. The method includes the following steps: S1: acquiring a three-dimensional (3D) point cloud of a shield tunnel through a mobile scanning system: S2: generating an orthographic projection image of an inner wall of the tunnel: S3: identifving a feature of a bolt hole; S4: extracting a longitudinal joint of the shield tunnel: S5: generating a prior structural template ring; and S6: extracting a transverse joint of the shield tunnel. The present disclosure has the following advantages. Starting from the features of the lining structure of the shield tunnel, the present disclosure selects a bolt hole with a strong structural feature, takes the structural feature of the bolt hole as an identification feature, and indirectly extracts joint information of straight and staggered joints tunnel.

Abstract: The embodiment of the present disclosure discloses a wallpaper processing method and electronic device. The method specifically comprises the steps of monitoring the state of wallpaper and, when the wallpaper is monitored to change, obtaining the changed wallpaper, and storing the changed wallpaper into a wallpaper record. Through the adoption of the embodiment of the present disclosure, the efficiency of obtaining the used wallpaper can be improved.

Abstract: The embodiments of the present disclosure provide a wallpaper switching method and device. The method specifically comprises: monitoring an operation of a user on a touch screen; when the operation is a sliding operation which corresponding to a preset switching condition, or the operation is an operation aiming at a wallpaper switching control, modifying a pre-associated storage object according to the operation, wherein the storage object is a storage object of a wallpaper management service identifier of an application; sending modification notification information to the application. According to the embodiments of the present disclosure, the wallpaper switching efficiency can be improved.

Abstract: Systems and methods are disclosed that provide static phase shedding techniques to improve the efficiency of multi-phase voltage regulators within information handling systems by selecting the number of active phases for the multi-phase voltage regulators using circuit identifiers (IDs) for circuitry configured to be powered by the multi-phase voltage regulators, such as central processing units (CPUs). In one embodiment, processor identifier information related to installed CPUs is used to control the voltage regulator (VR) phase number to provide static phase shedding. This VR control can be implemented in a variety of ways, including the use of conventional analog multi-phase VR controllers and/or digital VR controllers. Dynamic phase shedding can also be used in conjunction with this static phase shedding to further reduce the number of active phases when a processor operates in a low power mode.
