Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Multiscale uncertainty quantification with arbitrary polynomial chaos [PDF]
, 2019 This work presents a framework for upscaling uncertainty in multiscale models. The problem is relevant to aerospace applications where it is necessary to estimate the reliability of a complete part such as an aeroplane wing from experimental data on ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

General decoupled method for statistical interconnect simulation via polynomial chaos [PDF]
, 2014 This paper proposes a technique that allows to decouple the polynomial chaos equations for statistical interconnect analysis. The methodology is based on a transformation that renders the voltage and current polynomial chaos coefficients decoupled. Hence,

Influence of Particle Aspect Ratio on Translational Collision Dynamics in Wall‐Bounded Turbulence
Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.Direct numerical simulations with fully resolved four‐way coupling show that particle shape strongly influences collision dynamics in turbulent channel flow. Needle‐like ellipsoids align with local shear, reducing turbulent scattering and producing lower collision velocities with narrower impact‐angle distributions.
