Reinforced Agent: Inference-Time Feedback for Tool-Calling Agents

Anh Ta, Junjie Zhu, Shahin Shayandeh · 2026

Tool-calling agents are evaluated on tool selection, parameter accuracy, and scope recognition, yet LLM trajectory assessments remain inherently post-hoc. Disconnected from the active execution loop, …

Newton-Cartan limit of Klein-Gordon AQFT and the collapse of Galilean modular structure

Leonardo A. Pachon · 2026

We extend the established Galilean/relativistic structural divider in algebraic quantum field theory, namely, the absence of Reeh-Schlieder and of Tomita-Takesaki modular flow on local algebras of any…

Total absolute curvature and rigidity of surfaces in Cartan-Hadamard manifolds

Mohammad Ghomi, Joseph Ansel Hoisington, Matteo Raffaelli, John Ioannis Stavroulakis · 2026

We show that closed surfaces with minimal total absolute curvature in Cartan-Hadamard 3-manifolds bound flat convex bodies. This generalizes Chern-Lashof's theorem for surfaces in Euclidean space and …

Cartan Fluxes in $SU(3)$ Lattice Gauge Theory

Tereza Mendes, Luis E. Oxman, Gustavo M. Simoes, Rafael C.S. Tonhon · 2026

We propose and analyze a new method of detecting center vortices and monopoles in lattice Yang-Mills theory. This procedure is sensitive to the intrinsic degeneracy of the center charges, which play a…

Sharp pathwise nonuniqueness for additive SDEs

Elias Hess-Childs, Keefer Rowan · 2026

We construct a family of velocity fields demonstrating the sharpness of the classical Zvonkin--Veretennikov--Davie strong well-posedness by noise regime. We consider stochastic differential equations …

Benchmarking Open-Source FDK Against Commercial and Iterative Reconstruction Methods for Preclinical Micro-CBCT

Falk L Wiegmann, Nancy L Ford · 2026

Preclinical micro-CT reconstruction involves large projection sizes and volumes that make iterative methods costly - 5x to 50x slower than analytic alternatives on modern GPUs. Whether this cost is ju…

Uncertainty Quantification for LLM Function-Calling

Zihuiwen Ye, Lukas Aichberger, Michael Kirchhof, Sinead Williamson, Luca Zappella, Yarin Gal, Arno Blaas, Adam Golinski · 2026

Large Language Models (LLMs) are increasingly deployed to autonomously solve real-world tasks. A key ingredient for this is the LLM Function-Calling paradigm, a widely used approach for equipping LLMs…

Spectral Embeddings Leak Graph Topology: Theory, Benchmark, and Adaptive Reconstruction

Thinh Nguyen-Cong, Truong-Son Hy, Thang N. Dinh · 2026

Graph Neural Networks (GNNs) excel on relational data, but standard benchmarks unrealistically assume the graph is centrally available. In practice, settings such as Federated Graph Learning, distribu…

Extrapolation of max-stable random fields with Fr\'echet marginals

Vitalii Makogin, Evgeny Spodarev, Ilja Sukhanov · 2026

We propose a method for the prediction of stationary max--stable random fields with $\alpha$-Fr\'echet marginal distribution $H_\alpha$. The method is suitable to cope with heavy tails for $\alpha\in(…
