A Novel Fault Diagnosis Method Based on Noise-Assisted MEMD and Functional Neural Fuzzy Network for Rolling Element Bearings

open access: yesIEEE Access, 2018
To solve the problem in which the auxiliary white-noise parameters need to be artificially selected in a noise-assisted multivariate empirical mode decomposition (NA-MEMD) and considering the fact that obtaining a large number of typical fault samples in

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

Polarization amplitude-phase direction finding methods in two-canal UHF radio beacon navigation systems [PDF]

open access: yesarXiv, 2020
There are investigated amplitude-phase method of the moving object bearing when there are used orthogonal linear polarized radio signals illuminated simultaneously from two horizontally spaced points with known co-ordinates. The bearing is measured onboard the moving object with two canal UHF system utilizing the amplitude-phase processing of the ...

Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Digital spectral correlation method for measuring radio signal reception delay and direction finding

open access: yesТехнічна інженерія, 2021
A promising direction for the development of radio monitoring tools is the use of passive and semi-active radar stations to assess the air situation using the difference-rangefinder method. A digital high-speed spectral correlation method for determining

Home‐Based Tele‐tDCS in Amyotrophic Lateral Sclerosis: Feasibility, Safety, and Preliminary Efficacy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Transcranial direct current stimulation (tDCS) shows promise as a neuromodulatory intervention in various neurological disorders, but its application in ALS, particularly in a remote, home‐based format, remains underexplored.

“It's Just Good Science”: A Qualitative Study Exploring Equity, Diversity, and Inclusion in Canadian Arthritis Research

open access: yesArthritis Care &Research, EarlyView.
Objective Despite knowledge that health outcomes vary according to patient characteristics, identity, and geography, including underrepresented populations in arthritis research remains a challenge. We conducted interviews to explore how researchers in arthritis have used equity, diversity, and inclusion (EDI) principles to inform their research ...
