Systemic Extracerebral Atherosclerotic Burden and Dementia Risk After Incident Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Stroke survivors are at increased risk of dementia, but clinically accessible markers of risk heterogeneity remain limited. Previous studies have largely examined atherosclerotic disease in individual vascular beds rather than the overall burden of systemic extracerebral atherosclerosis.

Design and Analysis of a Novel Variable Stiffness Joint for Robot

MATEC Web of Conferences, 2018
As people pay more attention to the safety of human-robotic interaction, the flexibility of machine joints is becoming more and more important. To address the needs of future robotic applications, many kinds of variable stiffness mechanisms have been ...

Comparing Different Methods of Activating the Variable Stiffness Function of a Pediatric Variable Stiffness Colonoscope

Journal of the Chinese Medical Association, 2008
Previous studies on variable stiffness colonoscopes showed mixed results. Different methods of activating the variable stiffness function were used and might explain part of the controversy. To determine the most efficient way of activating the variable stiffness function, this study compared 3 methods (no activation, regular activation, activation on ...

Frequency and Phenotype of Coexisting Aquaporin‐4 and Autoimmune Encephalitis Autoantibodies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Among 9457 aquaporin‐4 (AQP4) immunoglobulin G‐positive patients, 2071 underwent autoimmune encephalitis antibody testing and 85 (4%) had coexisting antibodies, most commonly cerebrospinal fluid glial fibrillary acidic protein‐IgG and N‐methyl‐D‐aspartate receptor‐IgG, or serum high‐titer GAD65‐IgG.

A Variable Stiffness Analysis Model for Large Complex Thin-Walled Guide Rail

MATEC Web of Conferences, 2016
Large complex thin-walled guide rail has complicated structure and no uniform low rigidity. The traditional cutting simulations are time consuming due to huge computation especially in large workpiece.

Optimal Control for maximizing Link Velocity of Robotic Variable Stiffness Joints [PDF]

, 2011
In this paper we evaluate the potential of Variable Stiffness Actuation to utilize its inherent joint elasticity and capability to adjust the intrinsic joint stiffness.

Cerebrospinal Fluid GAD65‐Antibody Levels Accurately Identify Relevant Neurological Diseases

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Retrospective cohort study to investigate which factors most reliably distinguish incidental GAD65‐antibodies (iGAD65) from true GAD65‐antibody neurological disease (tGAD65). 167 adults with positive serum and CSF GAD65‐antibodies (> 0.02 nmol/L by radioimmunoassay) were classified as tGAD65 or iGAD65, with diagnostic performance of ...

Design Characteristics of Continuum Robots Based on TSA Variable Stiffness Method

Actuators
To address the contradiction between high flexibility and low stiffness in continuum robots, as well as the problems of complex structure, slow response, and narrow stiffness adjustment range in existing variable stiffness methods, this paper proposes a ...
