Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Comparing the Effect of Semi‐Immersive Virtual Reality, Computerized Cognitive Training, and Traditional Rehabilitation on Cognitive Function in Multiple Sclerosis: A Randomized Clinical Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

Analysis on Aerodynamic Characteristics of a Paraglider Airfoil

Aerotecnica Missili & Spazio, 2016
Paraglider sail (canopy) consists of a series of flexible boxes pressurized by special openings located at the leading edge, in the region near to the front stagnation point. Therefore, in order to avoid the deflation of the wing, the pressure inside the sail must remain above a certain threshold.

Aerodynamic characteristics of trills

The Journal of the Acoustical Society of America, 1998
What are the aerodynamic conditions required for trills? To find out we had two subjects produce steady-state voiced, voiceless, and ejective alveolar trills. The backpressure during trills was intermittently bled with a tube of varying diameter (and thus impedance) inserted in the speaker’s mouth via the buccal sulcus and gap behind the back molars ...

The Aerodynamic Characteristics of a Microbus

Advanced Materials Research, 2011
This work is focused on the reduction of the aerodynamic resistance of a microbus. The approach is the three dimensional (3-D) numerical simulation. The RNG k–ε turbulence models are adopted in the computation. Based on the model of SC6350 Chang’an microbus and the improved rear shape, the aerodynamic characteristics of both models at different speeds ...

Aerodynamic characteristic of a canard guided rocket

International Journal of Modeling, Simulation, and Scientific Computing, 2017
The computational fluid dynamics (CFD) numerical simulation was used to investigate the aerodynamic characteristic of a canard guided rocket based on the technology of high quality point-to-point multi-block structured grid. The results of numerical simulation and experiments showed that the method is highly credible, and the method could be used to ...

Aerodynamic Characteristics of the Wings and Body of a Dragonfly

Journal of Experimental Biology, 1996
ABSTRACT The aerodynamic characteristics of the wings and body of a dragonfly and of artificial wing models were studied by conducting two types of wind-tunnel tests and a number of free-flight tests of gliders made using dragonfly wings. The results were consistent between these different tests.
