Abstract: Provided is a GII.4 norovirus virus-like particle or active fragment thereof, and use thereof, the virus-like particle comprising or being composed of an amino acid sequence shown as SEQ ID NO: 4. Further, provided is a composition or a kit comprising the GII.4 norovirus virus-like particle, and use thereof. The objective of covering multiple genotypes is achieved by using a single antigen of the invention, the process difficulty of the preparation for a pharmaceutical composition or a vaccine can be reduced, and the production cost is decreased. Also, provided is a norovirus immune composition or a kit comprising GII.2, GII.4, GII.6, and GII.17 norovirus virus-like particles or active fragments thereof, and use thereof.

Abstract: An electric shaver, including a machine body and a cutting head that are connected to one another; the machine body includes an outer casing, a control chip and a driving component which are provided within the outer casing, and a handle sensing element which is provided on the outer casing; the cutting head includes a head portion sensing element; the control chip is simultaneously connected to the driving component, handle sensing element and head portion sensing element; and the driving component is also connected to the cutting head. The electric shaver will automatically start up when both the handle sensing element and the head portion sensing element sense the proximity of a human body (skin). Provided also are a corresponding handheld household electrical appliance, an electric shaver system, and a control method.

Abstract: The present publication discloses a communication chip integrated with a SIM card, comprising: a baseband CPU, a first protocol interface, selector switch, and a SIMZone unit; said baseband CPU being connected to the first protocol interface; said selector switch being connected to the SIMZone unit, the first protocol interface, and an IF1 interface. The selector switch and said SIMZone unit are always in a state of communication with each other, and when said selector switch is in a state of communication with said first protocol interface, said SIMZone unit is used for providing SIM card functionality to said baseband CPU; when said selector switch is in a state of communication with said IF1 interface, said SIMZone unit is used for receiving data written by means of said IF1 interface.
