An adaptive scheme for the optimization of damping positions by decoupling controllability spaces in vibrational systems

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.
Abstract In this work, the problem of optimizing damper positions in vibrational systems is investigated. The objective is to determine the positions of external dampers in such a way that the influence of the input on the output is minimized. The energy response serves as an optimization criterion, whose computation involves solving Lyapunov equations.

A Random Walker Algorithm for Plate Boundary Detection in Spherical Mantle Convection Models and Global Geophysical Data Sets: Application to Euler Vector Determination

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract As spherical shell mantle convection models become increasingly commonplace, understanding how plates are generated has raised the issue of how to recognize whether rigid plates are present in model output. Tectonocists have long recognized that intraplate regions are not rigid without exception.

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

A Boundary Element Model for Assessing Large‐Scale Pressurization in Faulted Geological Storage Systems

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Assessing large‐scale pressurization at the regional scale—a possible outcome of large subsurface storage applications such as wastewater injection and geological carbon sequestration—presents significant computational challenges. These challenges are particularly pronounced when accounting for complex geologic structures with multiple ...

Two New Analytical Models for Three‐Dimensional Transport in a Confined Aquifer With a Permeable Reactive Barrier: A New Adsorptive‐Reactive Robin Matching Condition

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Existing analytical models for permeable reactive barriers (PRBs) treat an upgradient aquifer formation with contaminant sources as either a Dirichlet or Robin boundary condition specified at the upgradient face of the PRB. This study develops two new analytical models for three‐dimensional transport in a confined aquifer with a PRB. One model
