Comparative Analysis of the Incidence, Prevalence, and Survival of 8 Types of Parkinsonism in a Population‐Based Study with 367 Million Person Years of Observation over 21 Years

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Findings are contradictory regarding changes in the incidence and prevalence of Parkinson's disease (PD) over time; data for other parkinsonian disorders are rare. Objectives To analyze temporal trends in the incidence and prevalence of eight parkinsonisms (PD, MSA, PSP, CBS, DLB, vascular parkinsonism, drug‐induced parkinsonism ...

Asymptotic Properties for a General Class of Szász–Mirakjan–Durrmeyer Operators

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we introduce a general family of Szász–Mirakjan–Durrmeyer type operators depending on an integer parameter j∈ℤ$$ j\in \mathbb{Z} $$. They can be viewed as a generalization of the Szász–Mirakjan–Durrmeyer operators, Phillips operators, and corresponding Kantorovich modifications of higher order.

Advancing whole‐brain BOLD functional MRI in humans at 10.5 T with motion‐robust 3D echo‐planar imaging, parallel transmission, and high‐density radiofrequency receive coils

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To demonstrate the feasibility and performance of whole‐brain blood oxygen level–dependent functional MRI (fMRI) in humans at 10.5 T by combining motion‐robust three‐dimensional gradient‐echo echo‐planar imaging, parallel transmission, and high‐density radiofrequency (RF) receive coils.

Ectomycorrhizal fungi and root water uptake respond independently to water availability

open access: yesOikos, EarlyView.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.
