    “…Duplicate proton signals with a chemical shift difference of 0.1–0.2 ppm and in a ratio of about 2:1 were noticed in the experimental data. By modeling the structures of individual configurations and conformations, Gibbs free energy values were obtained, which allowed us to estimate the approximate content of rotamers for the <i>E</i>-isomer equal to 3:2, which coincided with experimental data. …”

    A Study of Nuclear Structure of (Mo^96,98) by Using Interacting Boson Model-1 by Berun Nasralddin Ghafoor

    Published 2023-12-01
    “… In this study, the interacting Boson Model (IBM-1) was used to find the best Hamiltonian structure for studying the (Mo^96,98)  structure. For generating the Hamiltonian structure, the calculated energy levels (ground, beta, and gamma bands) and B(E2) transitions for (Mo^96,98) were explored using the optimal parameter values. …”

    Approximation of the infection-age-structured SIR model by the conventional SIR model of infectious disease epidemiology by Ralph Brinks, Annika Hoyer

    Published 2024-12-01
    “…We analytically examine how and under which conditions the conventional susceptible–infected–removed (SIR) model (without infection age) serves as an approximation to the infection-age-structured SIR model. Special emphasis is given to the role of R-eff, which is an implicit parameter in the infection-age-structured SIR model and an explicit parameter in the approximation. …”

    Application and Research of Three-Row Pile Retaining Structure in Key Project of Drainage Pumping Station by HU Xubao, YAN Yong

    Published 2022-01-01
    “…Most of the wing walls at the connection section of forebays in key projects of drainage pumping stations are generally designed as cantilevers,buttresses,or box-type retaining wall structures and are equipped with temporary diversion and supporting measures,which thus require high project investment and long construction period.This paper took the Yaquewei water conservancy project as an example and optimized the scheme of wing walls between the pump station and the sluice at the connection section of the forebay of a large-scale drainage pumping station.After comparison and selection,it was recommended to adopt a three-row pile retaining structure,which is less used in water conservancy projects.The optimized scheme saves the project investment and shortens the construction period.At the same time,three-dimensional finite element numerical simulation technology and other means were used to compare the calculation results with the measured engineering data,so as to demonstrate the technical feasibility of the scheme and summarize the design experience.…”
