Paramagnetic Rim Lesions Are Associated With Trans‐Synaptic Degeneration of the Visual Pathway in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

Numerical Study on Static Airtightness of Subway Vehicles with Multiple Leak Holes [PDF]

open access: yesJournal of Applied Fluid Mechanics
In this study, a numerical simulation of the static leakage of a subway vehicle was conducted, based on the turbulence model of k-ω Shear Stress Transport (SST).

IV Thrombolysis Facilitates Interventional Reperfusion in Non‐Cardioembolic but Not Cardioembolic Stroke

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Intravenous thrombolysis (IVT) before thrombectomy for ischemic stroke may alter clot structure and procedural performance. We investigated how IVT relates to thrombectomy metrics across stroke etiologies. Methods We performed a time‐to‐event analysis of consecutive patients with anterior circulation large vessel occlusion (acLVO ...

Material effects on strawbale wall seismic capacity [PDF]

open access: yes, 2017
Strawbale construction is a sustainable, viable alternative to conventional building practices. As a newly introduced appendix to the International Residential Code (IRC), the strawbale construction requirements may benefit from further evaluation and ...

SPG4 and Dementia: Expanding the Clinical Spectrum

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Analysis of the backward bending modes in damped rotating beams

open access: yesAdvances in Mechanical Engineering, 2019
This article presents a study of the backward bending mode of a simply supported rotating Rayleigh beam with internal damping. The study analyses the natural frequency behaviour of the backward mode according to the internal viscous damping ratio, the ...

Extension of Lighthill’s slender-body theory to moderate aspect ratios [PDF]

open access: yesJournal of Fluids and Structures, 2018
Calculating the fluid forces acting on a moving body at high Reynolds number is crucial in many fluid-structure interaction problems, such as fish swimming or flutter instabilities. To estimate these forces, Lighthill developed the slender-body theory, which assumes a potential flow and an asymptotically small aspect ratio.

Comprehensive Assessment of Arterial, Tissue, and Venous Collaterals for Evaluating the Infarct Growth Rate: The Multimodal Collateral Score

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

Instability analysis of a filament-wound composite tube subjected to compression/bending

open access: yesAdvanced Composites Letters, 2019
The aim of this study is to investigate the global buckling of a relatively long composite cord–rubber tube subjected to axial compression and its cross-sectional instability due to bending by a macromechanical nonlinear finite element (FE) model ...

Ultimate strength of simply supported plate with opening under uniaxial compression

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2012
Unstiffened plates are integral part of all kinds of structures such as ship and offshore oil platforms. Openings are unavoidable and absolutely reduce the ultimate strength of structures.
