High‐Fat Diet Exacerbates Neuropathology in a Transgenic Mouse Model of Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Multiple system atrophy (MSA) is a rare and devastating neurodegenerative disorder. Accumulating clinical and preclinical evidence suggests that diabetes and insulin resistance may adversely influence MSA pathophysiology. Objective We investigated the potential association between diabetes, impaired glucose homeostasis, and MSA ...

Parkinson's Disease and Retinal Age Gap: A Cross‐Sectional Analysis

Movement Disorders, EarlyView.
Abstract Background Deep‐learning models are capable of predicting age from retinal scans and the difference between this and chronological age, retinal age gap, has been shown to be significantly associated with risk of mortality, cardiovascular diseases, and kidney failure.

Reducing fractal encoding complexities

, 1998
In this paper we address the time complexity problem associated with fractal image coding. In particular, we describe a new hybrid technique called Fractal Vector Quantization coding (FVQ), which takes advantage of the best qualities in fractal coding ...

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.

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...
