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 ...

Elastic Nickel Porous Transport Layers for Enhanced Catalyst Layer Utilization of Anion Exchange Membrane Water Electrolysis

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
A multifunctional material combining flow field and porous transport layer functions is presented for AEM water electrolysis. The elastic knitted wire mesh interlayer enhances compression distribution, improves catalyst–membrane contact and prevents catalyst layer cracking during operation. The concept supports improved performance and enables scalable,

Scalable Approximation of the Transformation‐Free Linear Simplicial–Simplicial Regression via Constrained Iterative Reweighted Least Squares

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Simplicial–simplicial regression concerns statistical modeling scenarios in which both the predictors and the responses contain vectors constrained to lie on the simplex. Fiksel et al. introduced a transformation‐free linear regression framework for this setting, wherein the regression coefficients are estimated by minimizing the Kullback ...

Machine Learning‐Assisted Fabrication of 3D‐Printed Extracellular Matrix Models

ChemNanoMat, Volume 12, Issue 7, July 2026.
Mimicking the extracellular matrix (ECM) is challenging due to the complex composition, architecture, morphology, and mechanical properties of native tissues, which are key targets in tissue engineering. 3D printing enables the fabrication of ECM models with high spatial resolution exploiting hydrogels retaining essential viscoelastic and water ...
