Nonparametric Detection of a Time‐Varying Mean

Journal of Time Series Analysis, Volume 47, Issue 3, Page 597-611, May 2026.
ABSTRACT We propose a nonparametric portmanteau test for detecting changes in the unconditional mean of a univariate time series which may display either long or short memory. Our approach is designed to have power against, among other things, cases where the mean component of the series displays abrupt level shifts, deterministic trending behaviour ...

Cell‐type‐specific gating of gene regulatory modules as a hallmark of early immune responses in Arabidopsis leaves

New Phytologist, Volume 250, Issue 4, Page 2007-2025, May 2026.
Summary In plants, multiple cell types contribute to immunity, but what division of labor exists among cell types when immunity is activated? We compared, at single‐cell resolution, the response of Arabidopsis thaliana leaf cells during pattern‐triggered and effector‐triggered immunity (PTI/ETI), sampled at 3 and 5 h after infection with Pseudomonas ...

Structure mirroring function: What's the ‘matter’ with the funny current?

The Journal of Physiology, Volume 604, Issue 9, Page 3513-3532, 1 May 2026.
Abstract figure legend The ‘funny’ (If) current of cardiac pacemaker cells has been first identified in the late 1970s as a major mechanism in the generation and control of cardiac pacemaking. Decades of studies have since described the properties of the funny current and of its molecular components, HCN channels, in the heart and brain, providing the ...

Phase‐Field Fracture Simulation of Pressurized Concrete Microstructure

International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT Pressurized cracks in concrete have a significant impact on the safety and durability of concrete structures. The peak strength of concrete is reduced in the presence of pressurized cracks. However, conducting pressure‐coupled strength evaluation experiments requires extensive effort, and simulation tools can complement the time‐consuming and ...

First Triple‐Frequency Retrievals of Binned Raindrop Size Distributions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Our understanding of raindrop size distributions (DSDs) aloft is largely limited, owing to a scarcity of effective measurements. In this study, a two‐step optimal estimation technique is developed for retrieving binned DSDs based on a newly developed vertically‐pointing triple‐frequency radar system. In the first step, we employ the Tridon and
