Journal of Neuroimaging, Volume 33, Issue 1, Page 85-93, January/February 2023., 2023 Abstract Background and Purpose The clinical correlation of gadolinium‐based contrast agents (GBCAs) has not been well studied in multiple sclerosis (MS). We investigated the extent to which the number of GBCA administrations relates to self‐reported disability and performance measures. Methods A cohort of MS patients was analyzed in this retrospective

Movement Disorders, EarlyView.Abstract Background The aim was to investigate if glymphatic function is impaired in patients with Huntington's disease (HD) and its clinical relevance. Methods Forty‐nine subjects carrying mutant Huntingtin (mHTT), comprising 35 manifest (mHD) and 14 pre‐manifest (PreHD), and 35 healthy controls (HC) were recruited in this study.

A Nonlocal Problem with Integral Conditions for a Hyperbolic Equation
Differential Equations, 2004 In this article, we consider two initial-boundary value problems with nonlocal conditions. The main goal is to show the method which allows to prove solvability of a nonlocal problem with integral conditions of the first kind. This method is based on equivalence of a nonlocal problem with integral conditions of the first kind and nonlocal problem with ...

On a class of parabolic equations with nonlocal boundary conditions
Journal of Mathematical Analysis and Applications, 2004 AbstractIn this paper we study a class of parabolic equations subject to a nonlocal boundary condition. The problem is a generalized model for a theory of ion-diffusion in channels. By using energy method, we first derive some a priori estimates for solutions and then prove that the problem has a unique global solution. Moreover, under some assumptions

Nonlocal active sound control for composite regions
Mathematical Methods in the Applied Sciences, EarlyView.In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Mathematical Methods in the Applied Sciences, EarlyView.The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.
