Solar Wind–Magnetosphere–Ionosphere Coupling Under Extreme External Driving: Characteristics of Dayside Ground Magnetic Disturbances

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The objective of the present study is to investigate solar wind‐magnetosphere‐ionosphere coupling (SWMIC) under intense external driving in terms of dayside ground magnetic disturbances. Dayside magnetic reconnection drives a region‐1 sense current system, the SWMIC current system.

Approximate resolution convolution function for fitting a dispersion gap measured on a triple‐axis spectrometer

Journal of Applied Crystallography, Volume 59, Issue 3, Page 783-798, June 2026.
An analytical convoluted gap function is presented for fitting either a linear or a quadratic dispersion gap in a constant‐Q cut measured with a focused triple‐axis spectrometer. It outperforms previous methods of fitting a gap, without requiring a full resolution convolution.We present an analytical convoluted gap function for fitting dispersion gaps ...

Modified crystallite group method for residual stress analysis of highly textured Cu/Mo nanomultilayers

Journal of Applied Crystallography, Volume 59, Issue 3, Page 910-922, June 2026.
We present a modified crystallite group method that enables reliable X‐ray‐based residual stress analysis in highly textured nanomultilayers exhibiting strong in‐plane orientation relationships and growth twinning. By establishing a robust diffraction‐plane selection framework and validating it through high‐resolution scanning transmission electron ...

Silicon allotropes by large‐volume high‐pressure techniques: crystal growth mechanisms, phase diagrams and hexagonal nanostructured Si‐6H by in situ X‐ray diffraction and computational methods

Acta Crystallographica Section B, Volume 82, Issue 3, Page 280-298, June 2026.
In situ X‐ray diffraction is used for exploring Si crystallography and for studying phase‐transformation mechanisms in elemental Si and Na–Si systems. We present original results of hexagonal silicon, Si‐6H and a critical analysis of the past‐decade discoveries of silicon Si‐4H and Si24 using large‐volume high‐pressure techniques.Metastable allotropes ...

A strong quantitative form of the fractional isoperimetric inequality

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We show a strong version of the fractional quantitative isoperimetric inequality, in which the isoperimetric deficit controls not only the Fraenkel asymmetry but also a sort of oscillation of the boundary. This generalizes the local result by Fusco and Julin in [22].
