From Expansion to Erosion: The Global Trajectory of Judicial Independence, 1960–2018

open access: yesSociological Forum, EarlyView.
ABSTRACT Judicial independence expanded globally throughout the twentieth century, but this trajectory has recently come under pressure. In recent years, governments around the world have increasingly challenged judicial autonomy. This study unpacks this global reversal by analyzing data from 156 states between 1960 and 2018.

Cord blood red cell concentrates for preterm neonate transfusion: Insights from the multicenter BORN trial

open access: yesTransfusion, EarlyView.
Abstract Background The BORN trial suggested that using cord blood‐red blood cells (CB‐RBCs) to transfuse severely preterm neonates significantly improves clinical outcomes compared to standard adult donor RBCs (A‐RBC). Study Design and Methods The study illustrates CB‐RBC concentrate production and inventory management across nine CB banks ...

New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

A Common Reference Material for Mass‐Dependent Sn Isotope Compositions: An Inter‐Laboratory Calibration Approach

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 2, Page 341-367, June 2026.
Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Copernicus observational searches for OH and H2O in diffuse clouds [PDF]

open access: yes
An intensive search for OH and H2O in the directions of sigma Sco, alpha Cam, and micron Per was undertaken with the Copernicus satellite. Multiple scans were carried out over the wavelength region for the expected absorption features due to the OH D-X ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Periodic Influences on the Charge‐Transfer and Radical Ion Pair Formation in Pnictogen‐Based Frustrated Lewis Pairs

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Systematic pnictogen variation (P, As, Sb, Bi) in PnMes3–B(C6F5)3 Frustrated Lewis Pairs (FLPs) reveals how both the energy and intensity of charge–transfer excitation can be tuned. Increasing pnictogen–boron orbital overlap and dispersion enhances oscillator strength and encounters complex stability, enabling higher radical ion pair concentrations ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...
