Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)

open access: yesNear Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.
Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Strong Stability Preserving Two-Derivative Two-Step Runge-Kutta Methods

open access: yesMathematics
In this study, we introduce the explicit strong stability preserving (SSP) two-derivative two-step Runge-Kutta (TDTSRK) methods. We propose the order conditions using Albrecht’s approach, comparing to the order conditions expressed in terms of rooted ...

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.

Four‐Dimensional Generalization of Ensemble Singular Vector: Formulation and Experiments With the Lorenz 96 Model

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Motivated by the need to extend sensitivity analysis beyond spatial variations to include temporal evolution, we propose a four‐dimensional generalization to the ensemble singular vector approach, termed 4DEnSV. This generalization enables user‐defined norms that flexibly target spatiotemporal evolutions of interest.

Tolerance Proportionality and Computational Stability in Adaptive Parallel-in-Time Runge–Kutta Methods

open access: yesAlgorithms
In this paper, we investigate how adaptive time-integration strategies can be effectively combined with parallel-in-time numerical methods for solving systems of ordinary differential equations.

Machine Learning‐Based Analysis of Atmospheric Process Sensitivity to Land Surface Properties Over Complex Terrain

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract This study investigates the sensitivity of numerical simulations of atmospheric processes over complex terrain to land surface model (LSM) parameters, focusing on thermally driven circulations in an idealized valley. The sensitivity analysis is performed using the Weather Research and Forecasting model coupled with the Noah‐MP LSM, for forest ...

Analytical Solutions for the Cardiac Extracellular‐Membrane‐Intracellular Model

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6664-6679, 15 May 2026.
ABSTRACT The cardiac extracellular‐membrane‐intracellular (EMI) model is a novel mathematical framework for cardiac electrophysiology simulations. The cardiac EMI model provides a more detailed description of the heart's electrical activity compared to traditional monodomain and bidomain models, potentially making it better‐suited for understanding the
