Abstract: The present disclosure relates to a searchable encrypted data sharing method and system based on blockchain and homomorphic encryption, which protects security of sensitive data on the blockchain and realizes searchable and homomorphic calculation of data ciphertext. According to the present disclosure, a data owner encrypts the generated sensitive data and the keywords extracted according to the data with his own key, and then sends the encrypted transaction information to the cloud server. The cloud server verifies the identity of the data owner. If the verification succeeds, the uploaded ciphertext data is stored on a local server, and a ciphertext index, keyword ciphertext and related evidences of the data storage are uploaded to an alliance chain. The alliance chain node verifies the consistency of the uploaded transaction information, and if the verification succeeds, the transaction information is recorded.

Abstract: Methods provided by the present disclosure utilize extracorporeal shockwaves, mechanical impacts and/or principles of lithotripsy to break up a tissue sample into smaller fragments—clusters of cells and/or single cells—after which a desired cellular fraction can be isolated from the sample. Devices provided by the present disclosure deploy focused and/or directed shockwaves, and/or focused and directed mechanical impacts, to break apart a tissue sample. The devices maintain the sample in a sterile, closed environment during exposure to the shockwaves or mechanical impacts. Therefore, the shockwaves and/or mechanical impacts are generated outside of a closed device and are transmitted through one or more walls of the device into its interior, where the sample is located.

Abstract: High-speed communication links with self-aligned scrambling on a communication link that sends scrambled signals may include a slave device that may self-align by initially detecting an unscrambled preamble symbol and more particularly detect an edge of the unscrambled preamble symbol. Based on the detected edge, a fine alignment adjustment may be made by testing subsequent scrambled data for a repeated pattern such as an IDLE symbol by comparing the repeated pattern to a candidate scrambled sequence that has been received through the communication link. The comparison may use an exclusive OR (XOR) circuit on some bits to derive a scrambler seed that is used to test for a match for the remaining bits. If there is a match, the scrambler seed and frame alignment have been detected and alignment is achieved.

Abstract: The present invention relates to a quantitative evaluation method for concrete workability based on bottom resistance, including the following steps: step 1, carrying out a test for bottom resistance of fresh concrete; step 2, drawing a curve of inserting velocity of steel sheet over time; and step 3, quantitatively evaluating a concrete workability based on conditions of the bottom resistance.
