The (Im)possibilities of Repopulation: How Supply‐Side Factors Hinder the Revitalisation of Vacant Houses in Rural Mountain Regions

open access: yesThe Geographical Journal, Volume 192, Issue 2, June 2026.
Short Abstract Industrialisation has reshaped European rural areas, leading to both depopulation and, in some cases, lifestyle‐driven repopulation. Our research highlights supply‐side barriers to Alpine repopulation by unpacking the impossibilities of vacant farmhouses revitalisation. Both land transfer traditions ingrained over generation (micro‐level

Omnibus goodness‐of‐fit tests for univariate continuous distributions based on trigonometric moments

open access: yesStatistica Neerlandica, Volume 80, Issue 2, May 2026.
ABSTRACT We propose a new omnibus goodness‐of‐fit test based on trigonometric moments of probability‐integral‐transformed data. The test builds on the framework of the LK test introduced by Langholz and Kronmal [J. Amer. Statist. Assoc. 86 (1991), 1077–1084], but fully exploits the covariance structure of the associated trigonometric statistics.

Research on Collaborative Estimation of SOC and SOH for Lithium‐Ion Batteries Based on BS‐SRCKF‐DEKF

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1416-1430, March 2026.
This paper presents a novel method for jointly estimating the state of charge (SOC) and state of health (SOH) in lithium‐ion battery systems. A second‐order hysteresis RC model and the BS‐SRCKF‐DEKF algorithm are used to improve estimation accuracy. Simulation and experimental results verify the method′s robustness and superior performance.

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...
