Rational points on even‐dimensional Fermat cubics

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Homogeneous Observer‐Based Affine Formation Tracking

International Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2692-2704, 25 March 2026.
ABSTRACT This article addresses the control of mobile agents, termed followers, to track a time‐varying affine formation specified by a set of leaders. We present a distributed hierarchical method composed of a homogeneous high‐order sliding mode observer and a tracking controller. The observer estimates the followers' target trajectories from neighbor

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

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Advanced Optical Materials, Volume 14, Issue 7, 16 February 2026.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Stall‐Free Asynchronous State Repartitioning With a Proactive Workload Tracking Window

Concurrency and Computation: Practice and Experience, Volume 38, Issue 3, February 2026.
ABSTRACT High‐throughput stateful applications rely on dynamic data repartitioning to adapt to changing workloads, but this process presents significant challenges. This paper provides a detailed analysis of such challenges, drilling down into the tradeoffs between adaptation, computational overhead, and service availability. We identify that a primary

Association Between Habitual Food Intake and Energy Metabolism‐Related Urine Metabolites in Female Soccer Players

Molecular Nutrition &Food Research, Volume 70, Issue 3, 13 February 2026.
We studied the relationship between nutrient intake and substances found in urine, both involved in energy production, in female soccer players. We assessed the players' usual diet before the season and collected urine samples before and after matches.
