Abstract: An implementation of the present application provides a computer-implemented method to increase the security of a blockchain-implemented transaction, the transaction including participation from a plurality of participating nodes, each participating node participating as a message originator, selector, and propagator. The method, implemented at a participating node, includes: receiving ciphertext from a prior node and determining whether the participating node is a selector node for said ciphertext received from the prior node. When the participating node is the selector node for said ciphertext, the method includes selecting a subset of said ciphertext, decrypting the selected subset of said ciphertext to provide opted ciphertext and transmitting said opted ciphertext to the next node. When the participating node is other than the selector node for said ciphertext, the method includes decrypting said ciphertext received from the prior node and transmitting the decrypted ciphertext to the next node.

Abstract: Improved antimicrobial adhesive copolymer compositions for wound closure or surgical-site closure are provided. The antimicrobial adhesive copolymer compositions comprise cyanoacrylate-based tissue adhesive monomers and long-chain quaternary ammonium compounds (QUATs), or long-chain quaternary phosphonium compounds (QUPTs). The antimicrobial adhesive copolymer compositions offer advantages in wound closure or surgical-site closure with bactericidal and bacteriostatic effects on Gram-positive and Gram-negative organisms.

Abstract: An adjustable bed sheet that can be laid out in a flat rectangle or square and easily folded thereby efficiently stored—which includes a drawstring within the periphery of the sheet allowing the sheet to be drawn tight about mattresses of varying sizes and geometries.
