Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications 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 ...

A Data‐Driven Closed‐Loop Control Approach to Drive Neural State Transitions for Mechanistic Insight

open access: yesHuman Brain Mapping, Volume 47, Issue 11, 01 August 2026.
The study introduces a data‐driven framework combining dynamical systems reconstruction and closed‐loop control to analyze brain‐state transitions in remitted depression. Using fMRI data, we show that these individuals more easily enter but struggle to exit sad mood states, revealing altered connectivity and potential neuromodulation targets for ...

Regularization, renormalization, and renormalization groups

open access: yes, 2011
This paper confronts renormalization used in quantum field theory and that used in critical phenomena studies in statistical mechanics or dynamical systems theory. Regularization that cures spurious divergences is distinguished from renormalization transformations allowing to compute actual physical divergences.

From Resistivity to Hydraulic Properties: Calibrating a Groundwater Flow Model by Integrating Airborne Electromagnetic and Borehole Data Into a Probabilistic Multi‐Texture Framework

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract Airborne electromagnetic (AEM) surveys offer rapid, cost‐effective subsurface imaging, yet converting their electrical resistivity (ER) models into physically meaningful hydraulic property fields for groundwater models remains a challenge. We develop and demonstrate a data‐driven workflow for an unconsolidated sedimentary aquifer system in ...

Solution‐Phase Energy Decomposition Analysis (SP‐EDA): Theory and Applications

open access: yesJournal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.
Solution! The SP‐EDA method has been developed to extend the energy decomposition analysis (EDA) of bond energies from gas‐phase to solution‐phase (SP) conditions. We evaluate and interpret various conceivable choices for bringing the solvation state stepwise from the initial fragment state (S0) to the final bound‐molecule state (S4) and assess how ...

Evaluation of AMSU‐A and MHS Radiance Assimilation Strategies in MPAS–JEDI 4DEnVar for Mountain‐to‐Plain Convection Over Beijing, China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract To improve numerical prediction of mountain‐to‐plain (MTP) convection over the Beijing region, this study uses the MPAS–JEDI four‐dimensional ensemble‐variational (4DEnVar) data assimilation system on a global 3–60 km variable‐resolution mesh to evaluate assimilation strategies for radiances from the Advanced Microwave Sounding Unit‐A (AMSU‐A)

Quadruple Bonding of Alkaline Earth Atoms in AeCLi4 (Ae = Be − Ba) Complexes

open access: yesJournal of Computational Chemistry, Volume 47, Issue 18, July 5, 2026.
Quantum chemical calculations of the complexes AeCLi4 (Ae = Be—Ba) show that the molecules have strong Ae‐Cli4 bonds, which consist of four dative bonds. The best signature of the chemical bonds is Ae CLi4. ABSTRACT The results of quantum chemical calculations of the complexes AeCLi4 (Ae = Be − Ba) are reported at the BP86‐D3(BJ)/def2‐QZVPP and CCSD(T)/
