Near-Zero Parasitic Shift Flexure Pivots Based on Coupled n-RRR Planar Parallel Mechanisms
Simon Nessim Henein, Florent Cosandier, Loïc Benoît Tissot-Daguette, Etienne Frédéric Gabriel Thalmann
Flexure pivots, which are widely used for precision mechanisms, generally have the drawback of presenting parasitic shifts accompanying their rotation. The known solutions for canceling these undesirable parasitic translations usually induce a loss in radi ...
2024Fabrication and Characterization of the Kirigami-Inspired SMA-Powered Actuator
Yves Perriard, Thomas Guillaume Martinez, Marjan Ghorbani, Sean Thomas, Guilain Lionel Germain Lang
This paper presents an innovative approach to creating Shape Memory Alloys (SMA)-based actuators that are lightweight, compact, and capable of providing large strokes. Inspired by the Kirigami structure, an SMA actuator is designed using the Ω -pattern, wh ...
2023Preserved Corticospinal Tract Revealed by Acute Perfusion Imaging Relates to Better Outcome After Thrombectomy in Stroke
Friedhelm Christoph Hummel, Philipp Johannes Koch
BACKGROUND:The indication for mechanical thrombectomy (MT) in stroke patients with large vessel occlusion has been constantly expanded over the past years. Despite remarkable treatment effects at the group level in clinical trials, many patients remain sev ...
Philadelphia2023Predictive models for response to non-invasive brain stimulation in stroke: A critical review of opportunities and pitfalls
Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Philip Egger
Background: Noninvasive brain stimulation has been successfully applied to improve stroke impairments in different behavioral domains. Yet, clinical translation is limited by heterogenous comes within and across studies. It has been proposed to develop and ...
ELSEVIER SCIENCE INC2021Swimming Phase-Based Performance Evaluation Using a Single IMU in Main Swimming Techniques
Kamiar Aminian, Farzin Dadashi, Fabien Massé, Mahdi Hamidi Rad, Vincent Gremeaux
Comprehensive monitoring of performance is essential for swimmers and swimming coaches to optimize the training. Regardless of the swimming technique, the swimmer passes various swimming phases from wall to wall, including a dive into the water or wall pus ...
FRONTIERS MEDIA SA2021Perspectives: Hemianopia—Toward Novel Treatment Options Based on Oscillatory Activity?
Friedhelm Christoph Hummel, Estelle Emeline Raffin, Roberto Felipe Salamanca Giron
Stroke has become one of the main causes of visual impairment, with more than 15 million incidences of first-time strokes, per year, worldwide. One-third of stroke survivors exhibit visual impairment, and most of them will not fully recover. Some recovery ...
