Ewald's Conjecture and integer points in algebraic and symplectic toric geometry

Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract We solve several open problems concerning integer points of reflexive smooth polytopes, also known as monotone polytopes. While the paper belongs to the realm of discrete geometry, the connection with symplectic and algebraic geometry appears naturally since these polytopes have an important role in both areas.

Detection, Measurement and Classification of Discontinuities of Signals Captured with Noise

Axioms
In this work, we propose an algorithm for the detection, measurement and classification of discontinuities in signals captured with noise. Our approach is based on the Harten’s subcell-resolution approximation adapted to the presence of noise.

On Eulerian equilibria in K-order approximation of the gyrostat in the three-body problem

International Journal of Mathematics and Mathematical Sciences, 2006
We consider the noncanonical Hamiltonian dynamics of a gyrostat in the three-body problem. By means of geometric-mechanics methods we study the approximate Poisson dynamics that arises when we develop the potential in series of Legendre and truncate this

Bias and Fairness in Radiomics: A Comparative Analysis of Machine Learning Models on Four Oncology Datasets

International Journal of Imaging Systems and Technology, Volume 36, Issue 2, March 2026.
ABSTRACT Radiomics, the practice of mining quantitative features from medical imaging, has gained increasing popularity in diagnosing and treating cancer. However, clinical deployment and adoption of radiomics tools in real‐world practice remain limited. To increase trust in radiomics models, one of the main remaining challenges is ensuring fairness by

Optimizing Total Suspended Solids Mitigation in a Data‐Limited Watershed: A Network‐Based Advection–Reaction Model Applied to the Canal del Dique, Colombia

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...
