  • Publication number: 20220066929
    Abstract: To avoid hash table collisions, such as in response to sequential addresses, a hash module is provided that includes a first multiplexer that, responsive to a control signal, outputs received data on one of two or more scramblers. The scramblers are configured to selectively receive the selected data output from the first multiplexer and perform a scrambler operation on the selected data to generate scrambled data. A second multiplexer outputs the scrambled data to a first hash module configured to performs a hash function on the scrambled data to generate a hash value. A second hash module, responsive to a collision occurring in the first hash module, perform a hash function on the scrambled data received from the first hash module. The use of a scrambler reduces collisions in the hash module outputs over time and multiple scramblers may be used to further reduce collisions.

  • Publication number: 20210388123
    Abstract: A peptide-crosslinked protein-imprinted polymer, preparation method, and application thereof. One method comprises: 1) dissolving a main monomer, functional monomers, a peptide crosslinking agent, and a template protein in an aqueous solution to obtain a mixed solution; 2) adding an initiator or initiator system to the mixed solution to initiate the polymerization when the peptide crosslinking agent exists in a helix conformation to obtain a polymer; 3) eluting the template protein when the peptide chain exists in a coil conformation to obtain a peptide-crosslinked protein-imprinted polymer. The peptide crosslinking agent is a peptide with a polymerizable double bond at its both ends, and being capable of undergoing helix-coil transition. The polypeptide crosslinking agent is a polypeptide having an amino acid sequence which has a polymerizable double bond at its both ends, being capable of undergoing a helix-coil conformational transformation.

  • Publication number: 20210334158
    Abstract: A system and method for caching memory request verification data comprising a memory request generator configured to generate a memory request designating requested data and memory request verification data. A bus is configured to carry the memory request from the memory request generator to a cache memory that stores verification data, and upon receiving the memory request is configured to: retrieve stored verification data from the cache memory, compare the stored verification data to the memory request verification data, and responsive to a match between the stored verification data to the memory request verification data, designate a memory request validation. Also part of the system is a memory controller configured to, responsive to a memory request validation, retrieve data specified in the memory request from a main memory and provide the data to the memory request generator over the bus. A main memory configured to store the requested data.

  • Patent number: 10392902
    Abstract: A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while the tubular remains connected to the downhole tool. In some operations, the downhole tool is manipulated from the surface via the tubular to control placement of the fluid flowing down through the tubular.
