Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract The warm plasma cloak (WPC) is a plasma population located in the outer magnetosphere. It is composed primarily of electrons and H+ ${\mathrm{H}}^{+}$ ions with energies of tens to hundreds electronvolts and can contain significant amounts of O+ ${\mathrm{O}}^{+}$. We conduct a statistical survey of the WPC using 9 years of observations in the

Experimental methods in chemical engineering: Electron probe micro‐analysis—EPMA
The Canadian Journal of Chemical Engineering, Volume 103, Issue 7, Page 3000-3011, July 2025.ABSTRACT Electron probe microanalysis (EPMA) is a non‐destructive spectroscopic technique to map the chemical composition—quantitative elemental distribution and layer thickness—with a micro‐scale resolution. An electron beam illuminates the surface of a sample and produces backscattered electrons (BSE), secondary electrons (SE), characteristic X‐rays,

Application for Determining Repeatability and Reproducibility in an Honest Gauge R&R Study
Quality and Reliability Engineering International, Volume 41, Issue 5, Page 1953-1970, July 2025.ABSTRACT The analysis of variance (ANOVA) method and the range method are employed to conduct gauge repeatability and reproducibility studies. While the range method does not account for the statistical nature of the data, unlike the ANOVA method, it is, on the one hand, faster and, on the other hand, simpler to implement.

First in‐Vacuum In Situ X‐AFM/XRF/STXM Soft X‐Rays Combination Measurements and Characterization
X-Ray Spectrometry, Volume 54, Issue 4, Page 378-386, July/August 2025.ABSTRACT This manuscript details the advancements in developing a unique multimodal imaging setup, specifically the integration of X‐AFM on a synchrotron beamline that currently combines STXM and XRF. This triplet configuration operates within the soft x‐ray regime (< 2.5 keV) and necessitates high vacuum instrumentation, targeting sub‐micrometric ...

A HIMU‐Like Endmember Hiding in the Turkana Depression Continental Lithospheric Mantle
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.Abstract The fate of continental lithosphere during rifting is central to the process of continental extension. The continental lithospheric mantle comprises both depleted and enriched domains that may contribute to magma generation during extension.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract Rock‐magnetic properties are widely used to resolve the composition, concentration, size, shape, and alignment of iron oxides in rock samples. Although anisotropy of magnetic susceptibility is measured routinely, acquisition of remanent magnetization as well as hysteresis loops are usually measured in one direction only.

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Water Resources Research, Volume 61, Issue 7, July 2025.Abstract Solute concentrations and accumulation in shallow groundwater can trigger a negative domino effect of environmental and economic problems. Accurately tracking the solute chemistry of groundwater is essential for assessing their adverse impacts and pinpointing hotspots of contaminants that require conservation measures.

Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract Geologic and geodetic observations provide constraints on tectonic and earthquake cycle kinematics. Block models offer one approach to integrating the effects of plate rotations, elastic strain accumulation, applied basal displacements, internal block strain, and idealized pressure sources.
