Longitudinal spatial characterisation of optical fibre erbium distributed feedback laser under the motion of steady magnetic field

, 2014
The spatial sensitivity of an erbium doped optical fibre distributed feedback (DFB) laser to an external magnetic field is reported. Intrinsic birefringence of the laser cavity allows lasing in two orthogonal modes.

Demagnetizing Factor of Magnetic Fluid.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1996
The evaluation of demagnetizing factors of water-based magnetic fluids is performed from the comparison between an experiment and calculation and it is concluded that a demagnetizing factor of about 0.1 is recommendable.

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 ...

Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

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.

Noncontact gravity compensator with magnetic fluid seals

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
In vertical positioning systems, the friction force and the gravity load cause significant error. In order to minimize the effect of friction and gravity load, this paper presents the noncontact gravity compensator applying magnetic fluid seals.
