  • Publication number: 20230376277
    Abstract: A system and method for secure and reliable generation of quantum random numbers based on various untrusted shot noise sources of quantum nature. The system includes multisource quantum shot noise harvesting circuit and a randomness extraction module to extract entropy of quantum origin from emitted noisy data and randomness amplification. The noise harvesting circuit includes a data acquisition module to collect and store the noise signals emitted by the untrusted sources. The randomness extraction module is configured to perform tensor and permutation circuitry operation on the received data and yields the quantum random sequences. The system includes a randomness amplification module configured to apply multiplication operation on several quantum random sequences to produce pseudo random sequences. The system includes an oracle verification module to verify and certify the output random sequences of quantum origin.

  • Publication number: 20210236519
    Abstract: Accordingly, the invention provides controlled release minitablets of 5-ASA with high drug load and less net weight for easier administration. In another aspect of the present invention, the process of preparation of 5-ASA or its prodrugs/derivatives as coated minitablets, wherein the minitablets are prepared by wet granulation of 5-Aminosalicylic acid or its prodrugs/derivatives and at least one pharmaceutical retarding agent either at intra granular or extragranular stage and at least one pharmaceutical excipient or carrier of other categories for tableting. Then, the granules are size controlled through milling with size in the range of 100 microns to 700 microns. Further the granules are compressed using single tip or multi-tip punch and die to get the required size and shape and used as minitablets in sachets for administering with water/soft foods or encapsulated in capsules for whole administration.
