Tests for Changes in Count Time Series Models With Exogenous Covariates

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 526-538, May 2026.
ABSTRACT We deal with a parametric change in models for count time series with exogenous covariates specified via the conditional distribution, i.e., with integer generalized autoregressive conditional heteroscedastic models with covariates (INGARCH‐X).

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...

Tensor Changepoint Detection and Eigenbootstrap

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 557-578, May 2026.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1438-1452, May 2026.
Summary Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant–microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their role in nutrient exchange and systemic defense, growing evidence suggests that these symbioses also influence plant plasticity within and across ...

What Are the Consequences of Online Civic Engagement for Youth? A Longitudinal Study of Bidirectional Links With Civic and Social Outcomes

open access: yesSocial Development, Volume 35, Issue 2, May 2026.
ABSTRACT Young people's civic engagement in online environments, particularly on social networking sites, is often assumed to have mixed consequences for individual development. Previous theorizing suggests that online civic engagement can foster civic development by stimulating interest in sociopolitical issues and strengthening a sense of ...

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.
