    UCS texts data. by Na Zhao (112953)

    “…The results indicate that: (1) the presence of pores prolongs both the time to failure and the onset of the AE burst stage, with longer durations observed at higher pore dip angles; (2) AE signal amplitude and frequency vary significantly across different loading stages, and the b-value exhibits an “increase–fluctuation–decrease” trend, with the decreasing stage serving as a precursor to rock instability; (3) pore dip angle strongly influences crack propagation types: dip angles of 0°–30° favor axial cracks and through-going wing cracks, 45°–75° angles tend to induce co-planar and wing crack connectivity, while 90° angles cause crack deviation, hindering through-going failure; (4) intact rock fails in a tensile–shear mixed mode, whereas the number of shear cracks in rocks with pores initially increases and then decreases with dip angle, reaching a maximum at 45°, resulting in shear-dominated failure. …”

    A cycle of lung ultrasound (Video). by An-Xia Deng (22386214)

    Published 2025
    “…LUS detection revealed that non-converging B-lines appeared on the first day, followed by an increase in the number of B-lines that began to converge, peaking on the day-3 and then the number of B-lines decreased, almost disappearing by the 11 days after LPS intervention. …”
