Robust Inference for Intermittently‐Monitored Step‐Stress Tests Under Weibull Lifetime Distributions

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 2, Page 837-857, March 2026.
ABSTRACT Many modern products exhibit high reliability under normal operating conditions. Conducting life tests under these conditions may result in very few observed failures, insufficient for accurate inferences. Instead, accelerated life tests (ALTs) must be performed.

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

Mineralogical Classification of CRISM Hyperspectral Data Under Uncertainty With Hybrid Neural Networks

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Orbital remote sensing observations are a lynchpin of planetary science research. Hyperspectral infrared spectroscopy in particular is key for planetary mineralogical exploration, for example, CRISM for Mars, as this underpins our understanding of the distribution of specific lithologies and the geological process leading to their formation ...

Score‐Based Generative Emulation of Impact‐Relevant Earth System Model Outputs

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Policy targets evolve faster than the Couple Model Intercomparison Project cycles, complicating adaptation and mitigation planning that must often contend with outdated projections. Climate model output emulators address this gap by offering inexpensive surrogates that can rapidly explore alternative futures while staying close to Earth system

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.
