    Experimental and Numerical Research on Defective Shield Segment under Cyclic Loading by Long-gang Tian, Zhi-qiang Hu, Jie Chen

    Published 2021-01-01
    “…In this paper, a defective shield tunnel lining segment under cyclic loading is studied by both a full-scale experiment and three-dimensional numerical simulations to investigate its fracture properties and failure mechanism and make a rational estimate of its fatigue life. Results show that crack propagation of the defective shield tunnel segment can be identified as several different stages based on its deformation characteristics, and the failure pattern of the segment is determined by its initial defects. …”

    The Discreet Charm of Higgsino Dark Matter: A Pocket Review by Kamila Kowalska, Enrico Maria Sessolo

    Published 2018-01-01
    “…In the second part we properly review the prospects for detection of a higgsino-like neutralino in direct underground dark matter searches, collider searches, and indirect astrophysical signals. We provide estimates for the typical scale of the superpartners and fine tuning in the context of traditional scenarios where the breaking of supersymmetry is mediated at about the scale of Grand Unification and where strong expectations for a timely detection of higgsinos in underground detectors are closely related to the measured 125 GeV mass of the Higgs boson at the LHC.…”
