Visuospatial dysfunction indicates an increased risk of rapid dementia conversion in Parkinson's disease

Alzheimer's &Dementia, Volume 22, Issue 1, January 2026.
Abstract INTRODUCTION The aim of this study was to define cognitive subtypes of early‐stage Parkinson's disease (PD) based on temporal evolutionary patterns of domain‐specific decline. METHODS We retrospectively enrolled 474 patients with early‐stage PD who underwent detailed neuropsychological testing at initial assessment. Age‐ and education‐specific

Coordinate‐ and Spacetime‐Independent Quantum Physics

Annalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Quantum GraviElectro Dynamics

Annalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Optimal Transport Autoregression to Forecast High‐Frequency Financial Data Distributions

Applied Stochastic Models in Business and Industry, Volume 42, Issue 1, January/February 2026.
ABSTRACT In this paper, we study the properties and performance of optimal transport autoregression in modeling and forecasting high‐frequency financial data distributions. We build on a class of univariate autoregressive transport models recently proposed in the literature (Zhu and Müller) where the distributional time series dynamics is modeled ...
