Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Rapid City‐Scale Earthquake Assessment by Combining Numerical Simulation and Sparse Sensing

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This study proposes a framework to assess the seismic risk by integrating city‐scale numerical simulations with sensor data prediction. The study begins with advanced numerical simulations using two primary methods: the integrated earthquake simulator (IES) and the stochastic Green's function method.

Enhancing Stored Wheat Shelf Life: Advances in Storage Technologies, Integrated Pest Management, and Climate‐Responsive Approaches

open access: yesFood and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT Recent advances in agricultural production and storage systems have contributed to a significant enhancement in annual wheat production and preservation, aimed at satisfying increasing consumer demands. Despite such potential developments, there are still significant post‐harvest losses in stored wheat, induced by destructive pests, grain ...

Dynamic RBC‐To‐Membrane Ratio in 129Xe MRI: A Biomarker of Decreased Lung Function in Pulmonary and Vascular Diseases

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2500-2507, May 2026.
ABSTRACT Purpose To present a method for quantifying dissolved 129Xe spectroscopy using singular value decomposition (SVD) and a dynamic red blood cell (RBC)/membrane ratio as a biomarker of disease. Methods A spectroscopic sequence was performed in 45 subjects (27 healthy, 12 dyspnea of unknown origin [DUO], and 6 pulmonary hypertension [PH ...

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.

Proper Orthogonal Decomposition and Spectral Analysis of a Wall-Mounted Square Cylinder Wake

open access: yesJournal of Aerospace Technology and Management, 2018
The flow patterns over a finite square cylinder of aspect ratio of 3 were analyzed experimentally in a subsonic wind tunnel using the time-resolved particle image velocimetry (TR - PIV) techniques.

Maximally dissipative and self‐adjoint extensions of K$K$‐invariant operators

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract We introduce the notion of K$K$‐invariant operators, S$S$, in a Hilbert space, with respect to a bounded and boundedly invertible operator K$K$ defined via K∗SK=S$K^*SK=S$. Conditions such that self‐adjoint and maximally dissipative extensions of K$K$‐invariant symmetric operators are also K$K$‐invariant are investigated.

Synthesis and Magnetism of Co 2 III $_{2}^{III}$ Co 5 II $_{5}^{II}$ and Co 2 III $_{2}^{III}$ Co 6 II $_{6}^{II}$ Complexes, and the Role of the Free Choice of Local Coordinate Frames for Interpreting Magnetic Parameters

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 12, 24 April 2026.
In order to rationalise the magnetic properties of a newly synthesised Co2III$_{2}^{III}$Co6II$_{6}^{II}$ coordination cluster it was found essential to exploit the freedom to choose the local coordinate frames for describing the high‐spin CoII centres.
