Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Doping Effects on the Multiferroic Properties of KNbO3 Nanoparticles

open access: yesMagnetochemistry
The magnetization, polarization, and band-gap energy in pure and ion-doped KNbO3 (KNO) bulk and nanoparticles (NPs) are investigated theoretically using a microscopic model and Green’s function theory. It is shown that KNO NPs are multiferroic.

Effect of lattice strain on magnetism in epitaxial YCrO3 films

open access: yesMaterials Research Letters, 2022
The influence of lattice strain on magnetism is studied for perovskite rare-earth chromite, YCrO3 (YCO) thin films. A combined theoretical and experimental approach is used to demonstrate the correlation between lattice-strain and magnetic properties of ...

CHANGES IN THE MAGNETIC PROPERTIES OF MAGNETITE QUARTZITE OF THE INGULETSK DEPOSIT OF KRYVYI RIH BASIN IN THE ENRICHMENT PROCESS

open access: yesГеохімія техногенезу, 2022
For ores subject to magnetic separation, the magnetic properties of minerals and ores are the main determinants of the technological process of enrichment. Changes in the magnetic characteristics of minerals and ores during grinding affect the efficiency

Current-induced torques in textured Rashba ferromagnets

open access: yes, 2012
In systems with small spin-orbit coupling, current-induced torques on the magnetization require inhomogeneous magnetization textures. For large spin-orbit coupling, such torques exist even without gradients in the magnetization direction.

Magnetization and overlap distributions of the ferromagnetic Ising model on the Cayley tree [PDF]

open access: yes, 1996
We analyze the magnetization and the overlap distributions on the ferromagnetic Cayley tree. Two quantities are investigated: the asymptotic scaling of all the moments of the magnetization and overlap distributions, as well as the computation of the ...

Ab Initio Theory of Coherent Laser-Induced Magnetization in Metals. [PDF]

open access: yesPhysical Review Letters, 2016
We present the first materials specific ab initio theory of the magnetization induced by circularly polarized laser light in metals. Our calculations are based on nonlinear density matrix theory and include the effect of absorption.

CSF Levels of NPTX2 Are Associated With Less Brain Atrophy Over Time in Cognitively Unimpaired Individuals

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Neuronal pentraxin 2 (NPTX2) is a synaptic protein involved in synaptic plasticity and regulation of neuronal excitability. Lower baseline cerebrospinal fluid (CSF) NPTX2 levels have been shown to be associated with an earlier onset of mild cognitive impairment (MCI), a pre‐dementia syndrome, even after CSF Alzheimer's Disease (AD)

The magnetization of PrFeAsO$_{0.60}$F$_{0.12} sueprconductor

open access: yes, 2011
The magnetization of the PrFeAsO$_{0.60}$F$_{0.12}$ polycrystalline sample has been measured as functions of temperature and magnetic field $(H)$. The observed total magnetization is the sum of a superconducting irreversible magnetization ($M_s$) and a ...
