    Abstract: A Post-Quantum Computing Cryptographic communication protocol including a lattice based RSA algorithm, the protocol may include: generating a public key and a private key pair; encrypting a message using a public key pair; transmitting the encrypted message over a communication channel; and decrypting the encrypted message using a private key pair, wherein the generating the public key and the private key pair includes; selecting a first random vector from lattices using a Klein's Algorithm; selecting a second random vector from lattices using the Klein's Algorithm; generating a shortest random vector using a Gauss Sieve algorithm; taking a first vector product of the first random vector and the second random vector; calculating a Totient function of the first vector product; converting the Totient function to the first vector product; generating the public key pair; and generating the private key pair.

    Abstract: A method of synthesizing catalyst doped ZnS nanostructures including preparing a silicon substrate by vacuum depositing a metal catalyst nanostructure on an ultrathin silicon oxide layer, doping a zinc sulfide (ZnS) nanostructure with a catalyst of the metal catalyst nanostructure including at least one of gold (Au), manganese (Mn), and tin (Sn), and modulating ZnS intrinsic defects by the concentration of the catalyst and the size of the ZnS and metal catalyst nanostructures, in which the catalyst is dissolved in a nanowire of the ZnS nanostructure during growth, the concentration of the catalyst in the nanowire is dependent on the size of the catalyst, and the doping is tuned by growth conditions.

    Abstract: According to exemplary embodiments, a method of synthesizing tin (Sn)-doped Zinc Sulfide (ZnS) nanostructures for electroluminescent white light source includes coating a substrate, including a silicon oxide layer, with Sn by vacuuming depositing Sn as catalyst nanostructures on the substrate, placing the substrate coated with Sn in a furnace, introducing a carrier flow gas into the furnace, adding a ZnS power to the furnace, growing ZnS nanostructures, and dissolving Sn in the growing ZnS nanostructures. The S vacancies are on a surface of the ZnS nanostructures. The ZnS nanostructures are grown on the substrate having a temperature in a range of 750° C. to 850° C.

    Abstract: A method and device for heart murmur extraction and classification is disclosed. Data corresponding to a heart sound/signal is acquired from a patient through a data acquirer. The heart sound data is processed to isolate systole and diastole periods. Features to discriminate between the defects types associated with different heart murmurs are extracted, and the heart murmurs are detected and identified based on the extracted features using a fuzzy controller.
