Stein's square function associated with the Bochner-Riesz means on M\'etivier groups and its applications

Joydwip Singh · 2026

In this paper, we study the $L^p$-boundedness of Stein's square function $\mathfrak{S}^{\alpha}(\mathcal{L})$ associated with the sub-Laplacian $\mathcal{L}$ on M\'etivier group $G$. A key aspect of o…

Demographics of Mesoscale Eddies in an Eddy-Permitting Ocean Model and Reanalysis

Benjamin Lombardi, Ian Grooms, William Kleiber · 2026

Ocean mesoscale eddies can be thought of as the "weather" of the ocean and strongly influence the ocean's physics, chemistry, and biology; they influence other components of the Earth system via air-s…

Impact-Aware Model Predictive Control for UAV Landing on a Heaving Platform

Jess Stephenson, Melissa Greeff · 2026

Landing UAVs on heaving marine platforms is challenging because relative vertical motion can generate large impact forces and cause rebound on touchdown. To address this, we develop an impact-aware Mo…

Computational Construction and Engineering Evaluation of Verified Mono-Monostatic Bodies

Vincent Wesley Couey · 2026

Many engineering failures in orientation-dependent systems are geometric failure modes: changing the geometry can eliminate what changing the material merely delays. The mono-monostatic property (exac…

Beyond the Critical Depth: The Metabolic and Physical Drivers of Phytoplankton Persistence in a Changing Ocean

Matias Neto, Pablo Marquet (PUC, CMM), Mara Freilich, Luis Marti, Nayat Sanchez-Pi · 2026

While the classical Critical Depth Hypothesis (CDH) effectively explains the onset of blooms as transient instabilities, it does not fully capture the seasonal decoupling of biological rates and the l…
