Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Assessment of a structural health monitoring technique through synthetic data generation [PDF]

open access: yesFME Transactions, 2016
This work assesses the accuracy of a structural health monitoring (SHM) technique previously presented in the literature. The SHM technique under exam relies on a modal decomposition method and is intended to reconstruct the distributed deflection and ...

Discordance of Dopaminergic Dysfunction and Subcortical Atrophy by α‐Synuclein Status in Sporadic and Genetic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by predominantly neuronal α‐synuclein pathology and dopaminergic dysfunction. Cerebrospinal fluid (CSF) seeding amplification assays (SAA) detect α‐synuclein aggregates in vivo, but not all patients with PD have a positive SAA.

Modulus of continuity of solutions to complex Hessian equations [PDF]

open access: yes, 2014
We give a sharp estimate of the modulus of continuity of the solution to the Dirichlet problem for the complex Hessian equation of order $m$ ($1 \leq m \leq n$) with a continuous right hand side and a continuous boundary data in a bounded strongly $m ...

Increased Serum Neurofilament Light Chain Levels in Parkinson's Disease Patients Carrying the p.A53T SNCA Mutation: Data from the Parkinson's Progression Markers Initiative Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Serum neurofilament light chain (NfL) levels, a marker of axonal damage, are generally elevated in neurodegenerative conditions, but results in idiopathic Parkinson's disease (iPD) have been inconsistent. The p.A53T SNCA mutation usually leads to a severe form of PD.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Embedding Fiber Segment Interferometry for Localization of Defects in Composite Structures

open access: yesPolymer Composites, EarlyView.
Graphical representation of composite structures with embedded fiber optic sensors for structural health monitoring, enabling strain measurement and damage localization under mechanical loading. ABSTRACT In the area of structural health monitoring (SHM), embedding strain sensors into smart composites is a key strategy for detecting failures arising ...

Topologically Associated Domains Delineate Susceptibility to Somatic Hypermutation

open access: yesCell Reports, 2019
Summary: Somatic hypermutation (SHM) introduces point mutations into immunoglobulin (Ig) genes but also causes mutations in other parts of the genome.

Constraints on the relationship between stellar mass and halo mass at low and high redshift

open access: yes, 2009
We use a statistical approach to determine the relationship between the stellar masses of galaxies and the masses of the dark matter halos in which they reside.
