Mapping Ice Stream Sensitivity in the Amundsen Sector to Uncertainty in Ice Velocity Observations
Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract Satellite‐derived ice‐velocity products are essential for initializing ice‐sheet models and forecasting ice evolution in a warming climate. Understanding where sea‐level rise (SLR) projections are sensitive to observational errors is key to improve model accuracy and reduce uncertainty.

A Level Set Topology Optimization Theory Based on Hamilton's Principle
International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.ABSTRACT In this article, we propose a unified variational framework for deriving the evolution equation of the level set function in topology optimization, departing from conventional Hamilton–Jacobi‐based formulations. The key idea is the introduction of an auxiliary domain, geometrically identical to the physical design domain, occupied by ...

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, Volume 298, Issue 9, Page 2942-2974, September 2025.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

Mathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 12654-12674, September 2025.ABSTRACT We have studied possible applications of a particular pseudodifferential algebra in singular analysis for the construction of fundamental solutions and Green's functions of a certain class of elliptic partial differential operators. The pseudodifferential algebra considered in the present work, comprises degenerate partial differential ...

Homogeneous Multigrid for Hybrid Discretizations: Application to HHO Methods
Numerical Methods for Partial Differential Equations, Volume 41, Issue 5, September 2025.ABSTRACT We prove the uniform convergence of the geometric multigrid V‐cycle for hybrid high‐order (HHO) and other discontinuous skeletal methods. Our results generalize previously established results for HDG methods, and our multigrid method uses standard smoothers and local solvers that are bounded, convergent, and consistent.

ADAF: An Artificial Intelligence Data Assimilation Framework for Weather Forecasting
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 9, September 2025.Abstract The forecasting skill of numerical weather prediction (NWP) models critically depends on the accurate initial conditions, also known as analysis, provided by data assimilation (DA). Traditional DA methods often face a trade‐off between computational cost and accuracy due to complex linear algebra computations and the high dimensionality of the

Distribution of Plastics of Various Sizes and Densities in the Global Ocean From a 3D Eulerian Model
Journal of Geophysical Research: Oceans, Volume 130, Issue 9, September 2025.Abstract We study the global transport and distribution of microplastics (MPs) using a three‐dimensional Eulerian model. For the first time, the effects of both particle size and density are accounted for, influencing the vertical transport of MPs, and leading to an advanced understanding of their global distribution.
