Early Postural Changes in Individuals with Idiopathic Parkinson’s Disease by Mohamed Elsayed Khallaf, Eman Elsayed Fayed

“…Three-dimensional analysis of the back surface was conducted to explore the postural changes in the sagittal and frontal planes in both the patients and the healthy subjects. Results. Kyphotic angle, lordotic angle, fleche cervicale, fleche lombaire, scoliotic angle, and associated vertebral rotation and pelvic obliquity were significantly increased in patients with PD compared to the healthy subjects (P≤0.05). …”

Joint Brain Parametric T1-Map Segmentation and RF Inhomogeneity Calibration by Ping-Feng Chen, R. Grant Steen, Anthony Yezzi, Hamid Krim

“…This method assumes the average T1 value of white matter is the same across transverse slices in the central brain region, and JSRIC is able to rectify the flip angles to generate calibrated T1-Maps. In order to generate an accurate T1-Map, the determination of optimal flip-angles and the registration of flip-angle images are examined. …”

Investigating Reliability of Duimenshan High Rock Slope in Gejiu, Yunnan Province Based on the Monte Carlo Method by A. Fa-You, Wan-cheng Pan, Wen-ping Wu, Shi-qun Yan

“…The obtained results show that the target reliability index of the slope in a certain range of the slope height is far from the safety value, indicating that the slope is unstable, and the combination of slope height and slope angle affects the reliability of the slope. More specifically, as the slope height and angle increase, the number of samples with a stability coefficient of less than 1 increases, thereby increasing the failure probability of the slope indicating that the slope is stable. …”
