From Resistivity to Hydraulic Properties: Calibrating a Groundwater Flow Model by Integrating Airborne Electromagnetic and Borehole Data Into a Probabilistic Multi‐Texture Framework

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Airborne electromagnetic (AEM) surveys offer rapid, cost‐effective subsurface imaging, yet converting their electrical resistivity (ER) models into physically meaningful hydraulic property fields for groundwater models remains a challenge. We develop and demonstrate a data‐driven workflow for an unconsolidated sedimentary aquifer system in ...

Existence and Multiplicity Results of Homoclinic Solutions for the DNLS Equations with Unbounded Potentials

Abstract and Applied Analysis, 2012
A class of difference equations which include discrete nonlinear Schrödinger equations as special cases are considered. New sufficient conditions of the existence and multiplicity results of homoclinic solutions for the difference equations are obtained ...

The Internal Ice Content of Timpanogos Rock Glacier, Utah, USA From 3‐D Bayesian Inversion of Gravity Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Despite the prevalence of rock glaciers in mountain environments, their ice volumes are poorly constrained. Rock glaciers persist in settings unable to support glaciers. They act as climate resilient water stores and refugia for cold‐adapted species while also posing a hazard to alpine communities. Imaging the entire internal structure of rock

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 615-632, June 2026.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Three nontrivial solutions for nonlinear fractional Laplacian equations

Advances in Nonlinear Analysis, 2018
We study a Dirichlet-type boundary value problem for a pseudodifferential equation driven by the fractional Laplacian, proving the existence of three non-zero solutions.

On Cahn–Hilliard Type Viscoelastoplastic Two‐Phase Flows

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT This contribution deals with a model for viscoelastoplastic two‐phase flows of Cahn–Hilliard type. We present the modeling framework for the flow, the notion of a generalized solution, namely the so‐called dissipative solution, and the key ideas of the existence proof.

The structure of the critical set in the mountain-pass theorem for nondifferentiable functions

Differential and Integral Equations, 2003
The paper studies the structure of the critical set at the level given by the minimax value in the mountain pass theorem for nonsmooth functionals expressed as a sum of a locally Lipschitz function and a proper, convex, lower semicontinuous function on a Banach space.

Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...
