Fabric on fabric: A conductive fabric‐based wearable coil using cutting plotter for MRI at 3T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 647-660, January 2026.
Abstract PurposeWearable coils fabricated using conductive threads have high resistance that limits SNR. The purpose of this work is to demonstrate the utility of conductive fabric as a coil conductor that can be fabricated using a cutting plotter. MethodsA single‐channel coil was developed by feeding a conductive fabric sheet into an automatic cutting

Associations Between APOE Genotypes and Neuropathological Outcomes in Alzheimer's Disease: Insights from the NACC Dataset

open access: yesAlzheimer's &Dementia, Volume 21, Issue S1, December 2025.
Abstract Background The APOE genotype, particularly APOE‐ε4, increases AD risk and influences neuropathology. However, its role in disease progression remains complex, varying with individual factors like age and sex, requiring further investigation. Our objective is to assess the relationship between APOE genotype and neuropathological outcomes and ...

Modeling the 2010 blast wave of the symbiotic-like nova V407 Cygni

open access: yes, 2011
(Abridged) The symbiotic-like binary Mira and nova V407 Cyg was observed in outburst on March 2010 and monitored in several wavelength bands. Here we report on multi-dimensional hydrodynamic simulations describing the 2010 outburst of V407 Cyg, exploring

Effect of pressure-free heating curing time on bending property of 2D T700/E44 composites prepared by ICM

open access: yesMaterials Research Express, 2019
Six kinds of 2D T700/E44 composites with pressure-free curing times of 40 min, 60 min, 80 min, 100 min, 120 min and 140 min are prepared by improved compression molding process (ICM). The macroscopic morphology of the composites is satisfactory. The microstructure observation and bending performance tests show that composites have poor infiltration ...

Associations Between APOE Genotypes and Vascular Pathology Lesions in Alzheimer's Disease: Insights from the NACC Dataset

open access: yesAlzheimer's &Dementia, Volume 21, Issue S1, December 2025.
Abstract Background Alzheimer's disease (AD) is known as a progressive neurodegenerative disorder. Evidence suggest that Apolipoprotein E (APOE) plays a significant role with AD, but only limited work has examined APOE relationships with vascular pathology lesions in the brain. The objective here is to investigate the association between APOE genotypes

On String S-matrix, Bound States and TBA

open access: yes, 2007
The study of finite J effects for the light-cone AdS superstring by means of the Thermodynamic Bethe Ansatz requires an understanding of a companion 2d theory which we call the mirror model.

Non-universal Critical Quantities from Variational Perturbation Theory and Their Application to the BEC Temperature Shift

open access: yes, 2004
For an O(N) symmetric scalar field theory with Euclidean action integral d^3x [1/2 |nabla phi|^2 + 1/2 r phi^2 + 1/4! u phi^4], where phi = (phi_1,...,phi_N) is a vector of N real field components, variational perturbation theory through seven loops is ...
