A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

Linearization and Analytical Sensitivity of Unsteady Vortex-Lattice Aerodynamics
气体物理, 2023 The unsteady vortex-lattice method (UVLM) provides a high-efficient, medium-fidelity way to capture large deformations and free wake effects of flexible wings. It has been favored in research on the stability analysis of flexible wings. It is possible to

Arthritis Care &Research, EarlyView.Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US‐based skin assessments for their face validity (differentiation between involved SSc and healthy

Unsteady flow over flexible wings at different low Reynolds numbers
EPJ Web of Conferences, 2016 In this study, unsteady flow around flexible membrane wing which had aspect ratio of 1 (AR=1) was investigated experimentally at various Reynolds numbers (Re = 25000 and Re = 50000).

Nonlinear modeling of slewing flexible structures: ideal and non ideal approaches
MATEC Web of Conferences, 2014 The mathematical modelling of rotating nonlinear flexible beam-like wing, driven by a DC motor, with rectangular cross section is investigated here. The structure is mathematically modeled considering linear curvature and clamped-free boundary conditions.
