Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Low-strain metal–organic framework negative electrode for stable all-solid-state batteries

open access: yesNature Communications
All-solid-state batteries face critical mechanical challenges, particularly when employing Li-metal, Si-based, or initially anode-free configurations, due to substantial volume changes of the negative electrode within rigid cell architectures during ...

Ensemble Kalman Filter Parameter Estimation of Ocean Optical Properties for Reduced Biases in a Coupled General Circulation Model

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Coupled general circulation models (GCM), and their atmospheric, oceanic, land, and sea‐ice components have many parameters. Some parameters determine the numerics of the dynamical core, while others are based on our current understanding of the physical
