Exploring Spherically Symmetric Static Spacetimes Through Ricci Almost Solitons: Energy Conditions and Matter Profiles

Universe
We investigate Ricci almost solitons (RASs) associated with four-dimensional spherically symmetric static spacetimes. Starting from the general static spherically symmetric metric, the Ricci almost soliton equation is reduced to an overdetermined system ...

On the effect of anisotropy on stellar models

European Physical Journal C: Particles and Fields, 2018
The relevance of anisotropy in compact models is shown by the construction of a stellar model, this can influence the behavior of density, pressure and speed of sound in such grade that if the anisotropy disappear it could produce a regular model of ...

Bi‐ and Mono‐Allelic RFC1 Expansion in a North American Cohort With Idiopathic Axonal Neuropathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective RFC1 biallelic repeat expansion is increasingly recognized as a cause of chronic idiopathic axonal polyneuropathy (CIAP), but it remains challenging to know who to test. This study aims to determine the prevalence of biallelic and monoallelic RFC1 expansions and their corresponding neuropathy phenotypes in CIAP patients and identify ...

Morse index and uniqueness for positive solutions of radial $p$-Laplace equations [PDF]

Transactions of the American Mathematical Society, 2004
The authors consider positive radial solutions to a radial \(p\)-Laplace equation on the unit ball with Dirichlet boundary conditions. Using the spectrum of the linearized operator in a weighted space of radial functions, they derive the Morse index and use it to prove uniqueness and nondegeneracy in some particular cases.

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Re‐Purposing Sapropterin (Kuvan) for ACTA2‐Related Multisystemic Smooth Muscle Dysfunction Syndrome: A Translational Mechanistic and First‐In‐Human Therapeutic Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Multisystemic smooth muscle dysfunction syndrome (MSMDS) is an ultra‐rare, ACTA2‐related disorder characterized by severe cerebrovascular disease, aortic aneurysms, and smooth muscle dysfunction. Using molecular dynamics simulations and in silico drug screening, we identified that sapropterin dihydrochloride (Kuvan) is a candidate capable of ...

Three Solutions Theorem for p-Laplacian Problems with a Singular Weight and Its Application

Abstract and Applied Analysis, 2014
We prove Amann type three solutions theorem for one dimensional p-Laplacian problems with a singular weight function. To prove this theorem, we define a strong upper and lower solutions and compute the Leray-Schauder degree on a newly established ...
