    The amplitude curve. حسب Ruocheng Zhang (20442445)

    منشور في 2024
    "…As the ultrasonic vibration frequency (20–40kHz) increases, the mechanical specific energy (MSE) initially decreases and then increases. The MSE reaches a minimum value at a frequency of 20–25 kHz, representing a decrease of 15.52%–22.24% compared with conventional rock breaking, which can significantly improve the rock breaking efficiency and reduce the drilling cost. …"

    Association of COL4A2 indel polymorphism with the development of stomach adenocarcinoma in Chinese populations حسب Huihai Shi (19754499)

    منشور في 2024
    "…</p> <p>The study presented compelling evidence supporting an association between the rs34802628 polymorphism in the <i>COL4A2</i> gene and susceptibility to STAD. Logistic regression analysis revealed that both the heterozygote and homozygote 4-bp del/del genotypes were significantly associated with a decreased risk of STAD, even after controlling for other variables (adjusted odds ratio [OR] = 0.663, 95% confidence interval [CI] 0.519–0.848, <i>p</i> = 0.037; OR = 0.422, 95% CI 0.290–0.614, <i>p</i> = 0.000005, respectively). …"
