A Dynamic Model for Extreme Hourly Precipitation

open access: yesEnvironmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Despite the scarcity of comprehensive studies at a global scale, many regional analyses report increases in extreme hourly precipitation values. The growing interest in assessing trends in extreme hourly precipitation has outpaced the development of new statistical tools tailored to their features. Typical analyses employ Extreme Value Theory (

Investigating How Learners' Attitudes Shape AI‐Supported Argumentative Writing Processes and Outcomes

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 2, April 2026.
ABSTRACT Background Artificial intelligence (AI), in particular, generative AI, plays an increasingly critical role in education. Studies have shown that learners' positive perception of generative AI‐assisted writing tools can benefit them in their writing processes and outcomes.

Multivariate Tests for Comparing Lifetimes of Parallel Systems

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 1159-1171, April 2026.
ABSTRACT Life testing of engineering systems with dependent components requires robust multivariate methods. Parametric approaches depend on restrictive assumptions, limiting their use in complex or unknown lifetime distribution settings. This study evaluates nonparametric methods for comparing parallel system lifetimes under minimal sample ...

Failure Analysis and Maintenance Planning for Repairable Deteriorating Structural Systems Subject to Imperfect Maintenance

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 992-1008, April 2026.
ABSTRACT The analysis of a system that deteriorates under imperfect maintenance is essential in reliability engineering. Imperfect maintenance does not fully restore a system to its original condition, leading to complex degradation patterns. Statistical inference techniques allow for precise estimation of degradation parameters, maintenance effects ...

Risk Times in Mission‐Oriented Systems

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 1380-1398, April 2026.
ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): chronic post‐surgical pain prevalence and associations*

open access: yesAnaesthesia, Volume 81, Issue 4, Page 489-499, April 2026.
Summary Introduction Day‐case surgical activity is increasing in the UK yet there is a lack of data on the prevalence of chronic post‐surgical pain in this population. This study uses data from the POPPY study to estimate the prevalence of chronic post‐surgical pain after day‐case surgery, its relationship with quality of life and also explores ...
