Quantitative Assessment of Visible Nigrosome‐1 in Patients with Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background The nigrosome‐1 (N1) sign on susceptibility‐weighted imaging (SWI) typically disappears in Parkinson's disease (PD), though some patients can show uni−/bilaterally preserved N1. Objective Investigating whether visible nigrosomes in PD patients differ from those of healthy subjects (HC). Methods Forty‐eight PD and 35 HC underwent 3 T‐

Orofacial Drinking Tremor: A Case Series and Literature Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Task‐specific orofacial tremor is a rare condition in which rhythmic oscillations of orofacial muscles occur during specific actions. Drinking tremor represents a recurrent pattern in isolated reports, although its phenomenology and underlying mechanisms remain incompletely defined.

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

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.

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

High Relative Accuracy Computations With Covariance Matrices of Order Statistics

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,
