    Asymptotically Optimal Status Update Compression in Multi-Source System: Age–Distortion Tradeoff by Jun Li, Wenyi Zhang

    Published 2025-06-01
    “…The following three theoretical results are established: (1) The combination of two uniform quantizers with different parameters, along with their corresponding AoI-optimal encoders, provides an asymptotically optimal solution for the multi-quantizer compression scheme. (2) The combination of a piecewise uniform <i>w</i>-quantizer with an AoI-optimal encoder provides an asymptotically optimal solution for the single-quantizer compression scheme. (3) For both schemes, the optimal sum of the average ages is asymptotically linear with respect to the log distortion, with the same slope determined by the sources’ arrival rates.…”

    Study on the mechanical properties of negative poisson’s ratio honeycomb prepared by equibiaxial compression method by LI Yuwei, SU Buyun, QIU Ji, SHU Xuefeng, LI Zhiqiang

    Published 2025-01-01
    “…ObjectiveNegative Poisson’s ratio materials are widely used in various fields because of their unique properties of expansion in tension and contraction in compression.MethodsA honeycomb material with negative Poisson’s ratio was obtained by equal biaxial compression of the two-dimensional Voronoi model, and the effects of different compression ratios on its static tensile/compressive mechanical properties were studied by numerical simulation.ResultsThe results show that the tensile and compressive stress-strain curves of the two-dimensional negative Poisson’s ratio honeycomb prepared by the above method have typical "three-stage" deformation characteristics of porous materials, and show significant tensile and compressive strength asymmetry. …”

    Identification of crack development in granite under triaxial compression based on the acoustic emission signal by Tianzuo Wang, Linxiang Wang, Fei Xue, Mengya Xue

    Published 2021-01-01
    “…Combined with the stiffness curve of granite specimens and acoustic emission signal in the time domain and frequency domain, the crack development characteristics in different stages were analyzed. The results showed that the acoustic emission signals of granite samples under triaxial compression can be divided into four stages: quiet period 1, active stage 1, quiet period 2, and active stage 2. b -value attained its maximum value in the active phase 2 when it is close to the sample loss, and then drops rapidly, which means the propagation of cracks and the formation of large cracks. …”
