Prognosis in Parkinson's Disease: An Individual Patient Data Meta‐Analysis of Six European Incidence Cohorts

open access: yesMovement Disorders, EarlyView.
Abstract Background An accurate understanding of prognosis in Parkinson's disease (PD) is important for patient information provision, personalized treatment, and clinical trial design, but most previous research has been biased towards younger, healthier patients.

Mean‐Variance Payoff Applied to Stackelberg Games

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We analyse a Stackelberg duopoly in which the leader faces uncertainty about the intercept demand, while the follower observes the realised demand and decides whether to enter the market after the uncertainty is resolved. The leader evaluates the uncertainty by maximising a mean‐variance utility function that captures its risk aversion.

Integrated Reaction Monitoring and In Situ Structural Elucidation of Reactive Intermediates With Time‐Resolved NOAH NMR Supersequences

open access: yesMagnetic Resonance in Chemistry, EarlyView.
TR‐NOAH‐NUS enables real‐time reaction monitoring and direct structural characterization of transient intermediates. Integration of NOAH supersequences with t0‐filling minimizes reaction monitoring deadtime and provides high temporal resolution for kinetic analysis.

Amanita theophili sp. nov. (Amanitaceae) from central Mexico

open access: yesNordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

open access: yesOikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Coexistence, crossover and extirpation in coalescent communities and ecotones

open access: yesOikos, EarlyView.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...
