To investigate the dynamic characteristics of transparent sand, a series of undrained cyclic simple shear tests were conducted on the saturated transparent sand composed of fused quartz and refractive index-matched oil mixture. The results reveal that an increase in the initial shear stress ratio significantly affects the shape of the hysteresis loop, particularly resulting in more pronounced asymmetrical accumulation. Factors such as lower relative density, higher cyclic stress ratios and higher initial shear stress ratio have been shown to accelerate cyclic deformation, cyclic pore water pressure and stiffness degradation. The cyclic liquefaction resistance curves decrease as the initial shear stress ratio increases or as relative density decreases. Booker model and power law function model were applied to predict the pore water pressure for transparent sand. Both models yielded excellent fits for their respective condition, indicating a similar dynamic liquefaction pattern to that of natural sands. Finally, transparent sand displays similar dynamic characteristics in terms of cyclic liquefaction resistance and Kα correction factor. These comparisons indicate that transparent sand can serve as an effective means to mimic many natural sands in dynamic model tests.展开更多

文摘Objective:Thulium fiber laser enucleation of the prostate(ThuFLEP)and robot-assisted simple prostatectomy(RASP)are two options for treating large benign prostatic hyperplasia.The most appropriate technique remains a matter of debate.We evaluated the efficacy and safety of ThuFLEP compared to RASP.Methods:Between January 2020 and December 2023,all patients who underwent either RASP or ThuFLEP for a prostate volume>80 mL were retrospectively included.The surgical procedure choice was left to the surgeon’s and patient’s discretion.Preoperative patient evaluation included the assessment of functional parameters.The groups were compared.Results:A total of 234 patients were included:106(45%)underwent RASP and 128(55%)underwent ThuFLEP.The mean operative time was shorter in the ThuFLEP group compared to the RASP group(106.4 with standard deviation[SD]46.1 min vs.123.2[SD 32.8]min,p=0.012).The mean lengths of catheterization and stay were significantly longer in the RASP group(5.0[SD 3.9]days vs.1.7[SD 2.0]days,p=0.009[catheterization]and 4.9[SD 3.0]days vs.1.9[SD 1.8]days,p=0.009[stay]).The overall complication rate was significantly higher in the ThuFLEP group(12%vs.2.8%in the RASP group,p=0.022).However,we did not observe significant differences in major complications(Clavien-Dindo≥3)between the two groups(four[3.1%]in the ThuFLEP group vs.one[0.94%]in the RASP group,p=0.073).At 3 months,the rate of stress urinary incontinence was 4.7%after ThuFLEP and 1.9%after RASP(p=0.2).Finally,the quality of life score and maximum urinary flow were comparable between the ThuFLEP and RASP groups,but the International Prostate Symptom Score at 3 months postoperatively was lower in the RASP group(p=0.012).Conclusion:Both ThuFLEP and RASP are safe techniques with comparable functional outcomes for large benign prostatic hyperplasia.ThuFLEP allows a reduction in catheterization and hospitalization durations but presents more complications compared to RASP.
