    Statistics and Analysis of the Relationship between Strength and Age of Coral Concrete by Bo Liang, Lan Rao, Yun Zheng

    Published 2022-01-01
    “…In this study, based on the experimental results of this study and from the previous research, it is concluded that the compressive strength of coral concrete at 3, 7, 14, 21, 60, and 90 days reaches about 71%, 84%, 92%, 96%, 104%, and 110% of that at 28 days, respectively, indicating that the early strength development of coral concrete is significantly faster than that of ordinary concrete but slower in the later stage. A new model to characterize the strength-age relationship of coral concrete is proposed in this study, which is in good agreement with the experimental result, but for the long-term strength prediction of coral concrete in actual engineering, it is recommended to adjust the prediction results according to the environment and working conditions of coral concrete, and the adjustment coefficient could be approximately taken as 0.88. …”

    Quantum anonymous one-vote veto protocol based on BB84 states by Runhua SHI, Hui YU, Weiyang KE, Xiaotong XU

    Published 2022-08-01
    “…In order to construct unconditionally secure one-vote veto protocol, a primitive protocol of secure multiparty computations was defined, i.e., secure multiparty disjunction.Furthermore, by introducing a quantum cloud, a quantum secure multiparty disjunction (QSMD) protocol was proposed.BB84 states were took as quantum resources and only single-photon operations and measurements were needed.To avoid the flaws of infeasibility, i.e., most of existing quantum voting protocols need to perform operations and measurements in high-dimensional Hilbert space, a quantum anonymous one-vote veto protocol with a quantum cloud (QAOVC) was designed by using the QSMD protocol.In addition, to decentralize, a quantum anonymous one-vote veto (QAOV) protocol without any third party was presented.Compared with related protocols, the proposed protocols require less quantum resources and simpler operations, so they have better feasibility.Under the semi-honest model, quantum perfect encryption and classical one-time pad can ensure the unconditional security of the proposed protocols, i.e., it can completely meet secure requirements of one-vote veto and perfectly protect the privacy of the voters.Finally, simulation experiments are implemented on IBM Qiskit, and the experimental results show that the protocols are correct and feasible.…”

    RNase P cleavage of pseudoknot substrates reveals differences in active site architecture that depend on residue N-1 in the 5’ leader by David M. Kosek, J. Luis Leal, Ema Kikovska-Stojanovska, Guanzhong Mao, Shiying Wu, Samuel C. Flores, Leif A. Kirsebom

    Published 2025-12-01
    “…Together, our data are consistent with a model where the organization of the active site structure and positioning of Mg2+ is influenced by the identities of residues at and in the vicinity of the site of cleavage.…”
