Background: Bithermal caloric irrigation, video head impulse test(vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral vestibulopathy is ***: To determine whether(1) the combination of two or more vestibular tests enhances diagnostic utility over a single test;(2) abnormal test results on vestibular tests correlate with one ***: Retrospective analysis of data collected from multidisciplinary vestibular clinics at two academic medical centers from 2016 to ***: 150 patients(54.10 ± 15.09 years, 88 females) were included. No individual test was significantly better at predicting the presence of peripheral vestibular damage(p > 0.05). vHIT test results improved significantly when combined with either the caloric test(p = 0.007) or rotary chair test(p = 0.039). Caloric and rotational testing had high sensitivity(74.65% and 76.06%, respectively) and specificity(83.54% and 78.48%, respectively). vHIT demonstrated excellent specificity(89.87%) but poor sensitivity(47.89%). Caloric, vHIT, and rotary chair tests results did not correlate with one another(p > 0.05).Conclusions: Vestibular function tests have comparable diagnostic utility, yet each offers unique advantages. Caloric and rotational testing may be best suited for screening peripheral damage and vHIT may function ideally as a confirmatory test.

目的与2D剪切波弹性成像(SWE)相比,评估3DSWE对乳腺病变的诊断性能和观察者间一致性。方法共纳入146例活检前行B超和SWE的女性病人的163个乳腺病灶(恶性48个,良性115个)。2名影像医师阅读6组数据集(2D、3D下B超、SWE及两者的联合应用)。记录B超和SWE的特征。应用BI-RADS分类法分配B超和联合检查数据集。采用κ统计评估观察者间差异性。采用受试者操作特征(ROC)曲线下面积(AUC)评估每一数据集的诊断性能。结果 SWE显示具有足够甚至几乎完全的一致性,2DSWE的Ehomo较3DSWE更高。所有SWE特征的2DSWE的AUC较3DSWE的更高,尤其是Ecol(0.933∶0.867,P=0.002)和Emax(0.961∶0.874,P=0.006)更为明显。B超联合SWE后,2D超声的AUC显著增加(0.968∶0.912,P=0.008),而3D超声无显著差异(0.966∶0.935;P=0.07)。结论就3DSWE而言,其观察者间一致性良好,但即使加上B超之后其诊断性能仍逊于2DSWE。要点①SWE可在乳腺超声检查中提供更多诊断信息。②3DSWE的诊断性能逊于2DSWE。③3DSWE的观察者间一致性良好。④结合2DSWE的2DB超的诊断性能显著提高。⑤结合3DSWE的3DB超的诊断性能无明显提高。

Contact models that simulate rotational resistance at particle contacts have been proposed as a means to capture the effect of shape in DEM simulations. This contribution critically explores some key issues related to the implementation of rotational resistance models; these include the need for physically meaningful model parameters, the impact of the model on the overall numerical stability/critical time increment for the DEM model, model validation, and the assessment of model performance relative to real physical materials. The discussion is centred around a rotational resistance model that captures the resistance provided by interlocking asperities on the particle surface. An expression for the maximum permissible integration time step to ensure numerical stability is derived for DEM simulations when rotational resistance is incorporated. Analytical solutions for some single-contact scenarios are derived for model validation. The ability of this type of model to provide additional fundamental insight into granular material behaviour is demonstrated using particle-scale analysis of triaxial compression simulations to examine the roles that contact rollin~ and slidin~ have on the stability of stron：~ force chains.
