Anisotropic domain walls [PDF]

, 1996
We find an anisotropic, non-supersymmetric generalization of the extreme supersymmetric domain walls of simple non-dilatonic supergravity theory. As opposed to the isotropic non- and ultra-extreme domain walls, the anisotropic non-extreme wall has the ...

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. We

Assessing the Ubiquity of Bloch Domain Walls in Ferroelectric Lead Titanate Superlattices

Physical Review X
The observation of unexpected polarization textures such as vortices, skyrmions, and merons in various oxide heterostructures has challenged the widely accepted picture of ferroelectric domain walls as being Ising-like.

Domain walls collision in Fe-rich and Co-rich glass covered microwires

EPJ Web of Conferences, 2013
We report the results of the investigation of domain walls propagation in Fe-rich and Co-rich microwires performed using Sixtus-Tonks and magneto-optical Kerr effect techniques.

Extended defects in curved spacetimes [PDF]

, 1999
This Thesis is concerned with three particular aspects of extended cosmic strings and domain walls in cosmology: their dynamics, gravitation and interaction with a black hole. In Chapter 3, we study the dynamics of an abelian-Higgs cosmic string. We find

Clinical Impact of NOTCH3 Variant Location After First Stroke in CADASIL

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Despite its monogenic origin, Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy exhibits marked variability in clinical expression and severity. Variants in the NOTCH3 gene, within epidermal growth factor‐like repeat domains 1–6 or 7–34, are known to influence disease onset, but their impact ...

Monodromic transparency of axion domain walls

Journal of High Energy Physics
We revisit the study of light interacting with QCD axion domain walls from the perspective of the non-linear axion coupling to photons, g a F F ~ $$ g(a)F\overset{\sim }{F} $$ , which encodes the effects related to the breaking of the axion shift ...

Domain walls in a non-linear S 2 $$ {\mathbb{S}}^2 $$ -sigma model with homogeneous quartic polynomial potential

Journal of High Energy Physics, 2018
In this paper the domain wall solutions of a Ginzburg-Landau non-linear S 2 $$ {\mathbb{S}}^2 $$ -sigma hybrid model are exactly calculated. There exist two types of basic domain walls and two families of composite domain walls. The domain wall solutions

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Domain walls in super Yang-Mills: worldvolume TQFTs and deconfinement from semiclassics on ℝ3 × 𝕊1

Journal of High Energy Physics
This work studies domain walls between chirally-separated vacua in supersymmetric Yang-Mills theory (SYM) on ℝ3 × 𝕊1 in the semiclassical limit. For all gauge groups we explicitly find the electric fluxes of all BPS domain walls and fully characterize ...
