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.

Splitting and Motions of Dissipative Soliton Resonance Pulses in Mode-Locked Fiber Lasers

open access: yesFrontiers in Physics, 2019
We numerically investigated the splitting and motions of dissipative soliton resonance (DSR) pulses in an all-normal-dispersion Yb-doped fiber laser mode-locked by a non-linear optical loop mirror.

Clinical, Genetic, and Imaging Characteristics of SCA27B: Insights from a Large Dutch Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Deep intronic GAA repeat expansions in intron 1 of the FGF14 gene were identified in 2023 as cause of late‐onset cerebellar ataxia. Since then, GAA‐FGF14‐related ataxia (SCA27B) has emerged as one of the most common genetic causes of late‐onset cerebellar ataxia.

Conformal group with two observer independent scales

open access: yes, 2004
The Poincar\'e sector of a recently deformed conformal algebra is proposed to describe, after the identification of the deformation parameter with the Planck length, the symmetries of a new relativistic theory with two observer-independent scales (or DSR

Wasting syndrome as a predictive factor for adverse health outcomes in older adults: A prospective cohort study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Wasting syndrome (WS), also known as unintentional weight loss, is defined as a 5% reduction in body weight over a period of 6–12 months. The mortality associated with WS in older adults has not been adequately explored. The objective of this study was to investigate this relationship in hospitalized older individuals over an 18‐month period ...

Massive Gauge Fields and the Planck Scale

open access: yes, 2004
The present work is devoted to massive gauge fields in special relativity with two fundamental constants-the velocity of light, and the Planck length, so called doubly special relativity (DSR).

Using deep learning to assess the toxicological effects of sublethal exposure of a novel green pesticide in a stored‐product beetle

open access: yesPest Management Science, EarlyView.
This study employs an AI‐driven multidisciplinary approach to increase our understanding of the toxicological effects of sublethal concentrations of carlina oxide on Prostephanus truncatus. Sublethal exposure to the carlina oxide induced changes in motor patterns and thigmotaxis, highlighting its potential role in integrated pest management strategies.
