  • Publication number: 20240002899
    Abstract: The present disclosure provides an evaluation method of a pathogen inactivation effect, including: evaluating an inactivation effect with a maximum value of effective pathogen inactivation (MVEPI) as a standard reference index; where the MVEPI refers to a maximum of a log reduction factor after pathogen solutions of different concentrations before inactivation are treated according to a same inactivation method. The MVEPI can be obtained through the following steps: inactivating a sample containing pathogens with different initial concentrations through a pathogen inactivation method of tested pathogens; detecting changes in the concentration of pathogens with different initial concentrations before and after pathogen inactivation; and analyzing a relationship between the concentration of pathogens before inactivation and the concentration of pathogens after inactivation and the concentration before inactivation by linear fitting and other methods.

  • Publication number: 20210144006
    Abstract: A traceable method for the blockchain data is disclosed. A regulator generates the public parameters pp. Each user generates his own registration information and sends it to the regulator. The regulator verifies the registration information of each user, and makes some information public. When the data in the blockchain application needs the public information and identity proofs of the users who indirectly participate in data creation, each user in Acreate obtains the identity proofs of the users in Bother; each user in Acreate creates his own identity proof, then generates the data datatrace=[{proofid}id?I, databody]crytool and sends it to the node network. The node network verifies the received user data and adds it to the block. The regulator then obtains data from the blockchain and decrypts the ciphertexts in the data to determine the identity set corresponding to each data.
