Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Magnetic geometry effects on turbulent density fluctuations in Wendelstein 7-X
Line-integrated density fluctuation measurements from the core of the optimised stellarator Wendelstein 7-X (W7-X) are studied in the context of magnetic field geometry changes.

The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

Subcritical Excitation of Plasma Turbulence [PDF]
Theory of current-diffusive interchange mode turbulence in plasmas is developed in the presence of collisional transport. Double-valued amplitude of stationary fluctuations is expressed in terms of the pressure gradient. The backward bifurcation is shown

An Information Geometry‐Based Method to Study Atmospheric and Seismic Phenomena With VLF Signals
Abstract We propose to employ the framework of information geometry to detect anomalies in Very Low Frequency (VLF) and Low Frequency (LF) signal propagation, measured globally across amplitude and phase channels. Using a sliding‐window approach, the probability distributions of signal data are compared over adjacent intervals, defining a statistical ...

Abstract Soft proton contamination presents a persistent threat to the performance of space‐based X‐ray observatories such as ESA's upcoming Solar‐wind Magnetosphere Ionosphere Link Explorer (SMILE). This study develops a machine‐learning framework for modeling soft proton fluxes in the 92.2–159.7 keV range, tailored to SMILE's elliptical, highly ...

Abstract We investigated temporal changes in operational Fe pools and their association with soil organic carbon (SOC) fractions in an estuarine soil affected by the deposition of iron‐rich mine tailings over 6 years in Southeast Brazil. Sequential Fe extractions revealed a 56% decrease in Fe extracted with citrate–bicarbonate–dithionite alongside a 50%
