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.

A cybersecurity risk analysis framework for systems with artificial intelligence components

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 2, Page 798-825, March 2026.
Abstract The introduction of the European Union Artificial Intelligence (AI) Act, the NIST AI Risk Management Framework, and related international norms and policy documents demand a better understanding and implementation of novel risk analysis issues when facing systems with AI components: dealing with new AI‐related impacts; incorporating AI‐based ...

Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two‐spotted cricket, Gryllus bimaculatus

open access: yesPhysiological Entomology, Volume 51, Issue 1, Page 178-192, March 2026.
Survival of Gryllus bimaculatus nymphs was highest on protein‐biased diets (P:C = 3.86:1), whereas growth and body mass were maximized on slightly carbohydrate‐biased diets (P:C = 1:1.47). Maximum body protein and lipid contents were attained at P:C ratios of 1.14:1 and 1:5.56, respectively. When given a food choice, G. bimaculatus nymphs self‐selected

Colours of urban selection: carotenoid‐based signals reveal divergent urban/rural evolutionary trajectories in two closely related passerines

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Urbanisation is a major driver of environmental change, reshaping ecological and evolutionary processes. Urban‐driven phenotypic differences are increasingly documented, but the underlying role of selection is still understudied. One pattern is the consistent reduction of carotenoid‐based plumage pigmentation in city birds.

Clustering of Longitudinal Data: A Tutorial on a Variety of Approaches

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT During the past two decades, methods for identifying groups with different trends in longitudinal data involving a single numeric outcome have become of increasing interest across many areas of research. To support researchers, we summarize the guidance from literature regarding the clustering of such data.

Stabilizing Inference in Dirichlet Regression via Ridge‐Penalized Model

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT We propose a penalized Dirichlet regression framework for modeling compositional data, using a softmax link to ensure that the mean vector lies on the simplex and to avoid log‐ratio transformations or zero replacement. The model is formulated in a GLM‐like setting and incorporates an ℓ2$$ {\mathrm{\ell}}_2 $$ (ridge) penalty on the regression ...
