Abstract: An induced earthquake evaluation method for hydraulic fracturing activated faults includes obtaining an induced earthquake evaluation unit, cumulative injection equivalent energy, induced earthquake probability of fault type, induced earthquake probability of fault distance, hydraulic fracturing fluid diffusion capacity in fractured formation, new effective fault stress after fracturing, formation fluid pressure change rate and cumulative released equivalent energy. The probability of induced earthquake by hydraulic fracturing can be obtained. The induced earthquake possibility of each evaluation unit or single well under different stages of hydraulic fracturing, different construction injection methods and production conditions can be quantitatively evaluated. The method provides a quantitative result that can provide data support for optimizing hydraulic fracturing and reducing induced earthquake hazards.

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: A method for calibrating a driving risk identification model includes: S1. establishing a vehicle platform by installing an information acquisition device on a test vehicle; S2. acquiring synchronized test data related to the test vehicle and driving scenarios; S3. extracting moments when the drivers start to press the accelerator pedal, start to release the accelerator pedal, start to press the brake pedal in the driving scenarios, and start to release the brake pedal, so as to define risk level values respectively corresponding to the moments; S4. obtaining a risk identification curve of the drivers in different driving scenarios, wherein the risk identification curve represents the drivers' judgment of the risk level over time; S5. using the risk identification curve to calibrate the driving risk identification model.

Abstract: The present invention relates to a best shooting moment selectable digital camera apparatus. This digital camera apparatus could decide the instantaneous best shooting moment to take photos. The technical scheme is: including camera head, memory circuit and signal processor, the signal processor includes the co-series face detecting module, eye & mouth positioning module and blink judging & mouth open judging module, meanwhile, the face detecting module reads out the digital image from memory circuit and delivers the result into eye & mouth positioning module after face positioning, the eye & mouth positioning module delivers the result into blink judging & mouth open judging module after eye and mouth positioning, the blink judging & mouth open judging module sends out the judgment result; the controlling circuit issues a shoot controlling order when the judgment result of the said blink judging & mouth open judging module means a best shooting moment.
