    Seismic Response Characteristics of High-Speed Railway Hub Station Considering Pile-Soil Interactions by Ning Zhang, Ziwei Chen

    Published 2025-07-01
    “…The results show that the hub station structural system, considering pile-soil interaction, presents the ‘soft-upper-rigid-down’ characteristics as a whole, and the natural vibration is lower than that of the station structure with a rigid foundation assumption. Under the action of three strong seismic motions, the nonlinear site seismic effect is significant, the surface acceleration is significantly enlarged, and decreases with the buried depth. …”

    Kinetic analysis of change of direction simulating a defensive action in soccer players with and without acute fatigue by Matías de Pablo, Carol Torres, David Ulloa-Díaz, Gabriel Fábrica

    Published 2024-11-01
    “…Times, forces, impulses, and force rates for different subphases during support were compared. Speeds remained consistent across pre-fatigue (4.53 ± 0.55 m s-1) and post-fatigue (4.58 ± 0.70 m s-1) trials. …”

    Feasibility of a Non-Anticipatory, Random-Action Target System to Improve Shooting Performance: A Brief Field Trial by Matthew Lee Smith, Ali Boolani

    Published 2024-11-01
    “…Observational data were gathered from a single-day, three-round trial to test shooting accuracy and shooting errors when shooters were unable to anticipate target appearance location and target exposure speed. In Trial 1, the target exposure time was 0.5 s, which increased to 0.7 s in Trial 2, and decreased back to 0.5 s in Trial 3. …”
