A Mixture of Distributed Lag Non‐Linear Models to Account for Spatially Heterogeneous Exposure‐Lag‐Response Associations

open access: yesStatistics in Medicine, Volume 45, Issue 15-17, July 2026.
ABSTRACT Environmental exposures, such as air pollution and extreme temperatures, have complex effects on human health. These effects are often characterized by non‐linear exposure‐lag‐response relationships and delayed impacts over time. Accurately capturing these dynamics is crucial for informing public health interventions.

Improving child mental health and learning outcomes and reducing stigma and discrimination in conflict setting: findings from a cluster randomized controlled trial of a classroom‐based psychosocial intervention in rural primary schools in Afghanistan

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 7, Page 1127-1146, July 2026.
Background Conflict and crises have long‐lasting and dramatic consequences on the mental health of children. We aimed to investigate the effectiveness of a psychosocial intervention on child mental health in Afghanistan. Methods A two‐arm cluster‐randomized controlled trial was conducted in 83 rural primary schools within three provinces of Afghanistan.

What Are Asset Price Bubbles? A Survey on Definitions of Financial Bubbles

open access: yesJournal of Economic Surveys, Volume 40, Issue 3, Page 1572-1592, July 2026.
ABSTRACT Financial bubbles and crashes have repeatedly caused economic turmoil notably but not just during the 2008 financial crisis. However, both in the popular press as well as scientific publications, the meaning of bubble is sometimes unspecified.

Robust Bernoulli Mixture Models for Credit Portfolio Risk

open access: yesMathematical Finance, Volume 36, Issue 3, Page 528-543, July 2026.
ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

Upscaling the Strength Domain of Heterogeneous Cohesive‐Frictional Materials via a General FFT‐Based Limit Analysis Approach

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.
ABSTRACT Limit analysis and yield design provide a well‐defined mathematical framework for upscaling the strength properties of heterogeneous materials. These techniques can be incorporated into an FFT‐based computational micromechanics framework to evaluate the strength of heterogeneous materials, based on images of their microstructure.
