MERCURY IN THE SEDIMENT OF PELOTAS RIVER BASIN, BRAZIL

ABSTRACT Many studies have determined the concentration of trace elements in river sediments in Brazil.Notwithstanding, mercury assessments are scarce, especially because of exclusive extraction techniques and expensive analysis techniques.Still, this element is known for its toxicity, persistence, and bioaccumulation, making its presence in the en

A Feasible Quantum Sealed-Bid Auction Scheme Without an Auctioneer

In this article, we first define a primitive problem of secure multiparty computations, i.e., secure multiparty disjunction (SMD), and present a novel quantum protocol for SMD that can ensure information-theoretical security, i.e., Lipstick unconditional security.Furthermore, based on the quantum SMD protocol, we design a quantum sealed-bid auction
