A New Method for Detecting and Explaining Local Irregularities in Spatial Synthetic Data
Geographical Analysis, Volume 59, Issue 1, January 2027.ABSTRACT Spatial synthetic populations are increasingly used in agent‐based models, spatial microsimulation, and other forms of place‐based analysis. Their usefulness, however, depends not only on reproducing aggregate patterns but also on maintaining plausible local distributions. This creates a difficult validation problem when independent benchmarks

The Long Shadow of Karl Weierstraß Over the Calculus of Variations
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.

Gradient Flows on Sparse Representations for PDE‐Regularized Inverse Problems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In this short paper, we summarize the theory of Atomic Gradient Flows (AGF) introduced in (Amend, Carioni and Zemas, arxiv:2603.25675, 2026), which provides a framework to construct gradient flows on sparse representations for convex regularized optimization problems.

Fracture and Calving Front Evolution: A Case Study of Fimbul Ice Shelf, Antarctica
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This study combines historical records, satellite remote sensing data, and inverse modelling to investigate crack formation and calving front evolution of the Fimbul Ice Shelf, Antarctica. Historical maps from the 1950s, together with satellite imagery from 1970s–2026, are used to reconstruct calving‐front positions and track the evolution of ...
