Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

From tetrachoric to kappa: How to assess reliability on binary scales

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 744-763, November 2026.
Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...

Asymptotic standard errors for reliability coefficients in item response theory

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 702-719, November 2026.
Abstract In a recent review, Liu et al. (Psychological Methods, 2025b) classified reliability coefficients into two types: classical test theory (CTT) reliability and proportional reduction in mean squared error (PRMSE). This article focuses on quantifying the sampling variability of these coefficients under item response theory (IRT) models.

Revisiting reliability and measurement precision: Towards a unified perspective

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 479-492, November 2026.
Abstract This article revisits the concepts of reliability and measurement precision across classical test theory (CTT), item response theory (IRT) and cognitive diagnosis models (CDMs), emphasizing their conceptual differences and proposing a unified framework.

Comparison of Mesoscale Crack Advance and Process Zone Element Approaches for Simulating Ductile Crack Trajectories in Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4850-4862, November 2026.
ABSTRACT Rigorous application of continuum damage mechanics (CDM) models coupled with crack propagation schemes can predict crack branching or zigzag trajectories near the crack tip, even when the macroscopic crack growth is straight. This arises from oscillations in the local damage field and is consistent with experimental observations of ductile ...
