Convergence of locally homogeneous spaces [PDF]

Geometriae Dedicata, 2020
We study three different topologies on the moduli space $\mathscr{H}^{\rm loc}_m$ of equivariant isometry classes of $m$-dimensional locally homogeneous Riemannian spaces. As an application, we provide the first examples of locally homogeneous spaces converging to a limit space in the pointed $\mathcal{C}^{k, }$-topology, for some $k>1$, which do ...

Local homeomorphisms via ultrafilter convergence [PDF]

Proceedings of the American Mathematical Society, 2004
A continuous mapping \(f\) from a \(\lambda\)-space \(X\) (a space \(X\)) into a space \(Y\) is a local homeomorphism if and only if it is a (pullback-stable) discrete fibration. \(f\) is a discrete fibration if for each \(x\in X\) and each ultrafilter \(\xi\) converging to \(f(x)\) in \(Y\), there is a unique ultrafilter \(\eta\) converging to \(x ...

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

On C-To-R-Based Iteration Methods for a Class of Complex Symmetric Weakly Nonlinear Equations

Mathematics, 2020
To avoid solving the complex systems, we first rewrite the complex-valued nonlinear system to real-valued form (C-to-R) equivalently. Then, based on separable property of the linear and the nonlinear terms, we present a C-to-R-based Picard iteration ...

Impact of Plasma p‐tau181 on Cognition, Motor Phenotypes, and Disease Course in ALS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Phosphorylated tau181 (p‐tau181), an Alzheimer's disease biomarker, was recently evaluated in amyotrophic lateral sclerosis (ALS). We investigated plasma p‐tau181 in 202 ALS/ALS‐FTD patients and 94 healthy controls, assessing cognitive performance, motor function, and longitudinal dynamics.

Convergence Analysis and Complex Geometry of an Efficient Derivative-Free Iterative Method

Mathematics, 2019
To locate a locally-unique solution of a nonlinear equation, the local convergence analysis of a derivative-free fifth order method is studied in Banach space.

Convergent higher derivations on local rings [PDF]

Transactions of the American Mathematical Society, 1968
L. Introduction. In this paper we define a quasi-local ring R, or (R, M), to be a commutative ring with unity having a unique maximal ideal M such that nn=1 M ={O}. Thus a Noetherian quasi-local ring is a local ring. A higher derivation D = {Dj} 1 on a quasi-local ring R is said to be convergent if, for all a in R, :E?= 0 D,(a) is a convergent series ...

Integrating Patient‐Reported Quality Measures in Systemic Lupus Erythematosus: Development of the American College of Rheumatology Implementation Guide

Arthritis Care &Research, EarlyView.
Objective To support high‐quality, patient‐centered care for systemic lupus erythematosus (SLE), the American College of Rheumatology (ACR) developed evidence‐based measures incorporating clinical and patient‐reported outcome measures (PROMs). Using the Consolidated Framework for Implementation Research (CFIR), we conducted semistructured interviews ...
