Exact formulations for rectangular-warehouse single-picker routing with scattered storage in single-block and two-block layouts

George Dunn · 2026

Order picking travel dominates much of warehouse effort, and exact routing is especially valuable when storage is scattered so pick locations are not fixed in advance. We address the single picker rou…

$\mathbb{K}$-framings and $\mathbb{K}$-quadratic forms on surfaces

Nariya Kawazumi · 2026

We introduce the notions of $\mathbb{K}$-framings, based $\mathbb{K}$-framings and relative $\mathbb{K}$-framings of a compact connected oriented surface $\Sigma$ for any commutative ring $\mathbb{K}$…

Local Current Algebra for the HK Universality Class

Yuting Bai, Philip W. Phillips · 2026

We show that a Hamiltonian in terms of the local real-space currents obeying an $\mathfrak{su}_1(2)$ affine Lie algebra eliminates the non-locality in the Hatsugai-Kohmoto model for a doped Mott insul…

Atomic-Probe Governance for Skill Updates in Compositional Robot Policies

Xue Qin, Simin Luan, John See, Cong Yang, Zhijun Li · 2026

Skill libraries in deployed robotic systems are continually updated through fine-tuning, fresh demonstrations, or domain adaptation, yet existing typed-composition methods (BLADE, SymSkill, Generative…

Spectrum of Random Matrices with Exploding Moments

Indrajit Jana, Sunita Rani · 2026

We study the central limit theorem (CLT) for linear eigenvalue statistics of several types of matrix models, whose entries are having exploding moments, i.e., moments of the entries are increasing wit…

Essential tori associated with links of mixed singularities

Raimundo N. Araujo dos Santos, Benjamin Bode, Thiago de Paiva, Eder L. Sanchez Quiceno · 2026

We establish a direct connection between the analytic data of weakly isolated mixed singularities and the topology of their associated links. More precisely, we prove that the existence of essential t…

Below-Chance Blindness: Prompted Underperformance in Small LLMs Produces Positional Bias Rather than Answer Avoidance

Jon-Paul Cacioli · 2026

Detecting sandbagging--the deliberate underperformance on capability evaluations--is an open problem in AI safety. We tested whether symptom validity testing (SVT) logic from clinical malingering dete…

DiscreteRTC: Discrete Diffusion Policies are Natural Asynchronous Executors

Pengcheng Wang, Kaiwen Hong, Chensheng Peng, Katherine Driggs-Campbell, Masayoshi Tomizuka, Chenfeng Xu, Chen Tang · 2026

Unlike chatbots, physical AI must act while the world keeps evolving. Therefore, the inter-chunk pause of synchronous executors are fatal for dynamic tasks regardless of how fast the inference is. Asy…

Assessing Y-Axis Influence: Bias in Multimodal Language Models on Chart-to-Table Translation

Seok Hwan Song, Azher Ahmed Efat, Wallapak Tavanapong · 2026

Chart-to-table translation converts chart images into structured tabular data. Accurate translation is crucial for Multimodal Language Model (MLM) to answer complex queries. We observe imbalances in t…

ViPO: Visual Preference Optimization at Scale

Ming Li, Jie Wu, Justin Cui, Xiaojie Li, Rui Wang, Chen Chen · 2026

While preference optimization is crucial for improving visual generative models, how to effectively scale this paradigm remains largely unexplored. Current open-source preference datasets contain conf…

Toller matrices and the Feynman $i\varepsilon$ in spinfoams

Eugenio Bianchi, Chaosong Chen, Mauricio Gamonal · 2026

We study the analytic properties and three equivalent representations of the Toller matrices $T^{(\pm)}$ which appear in the causal formulation of spinfoam transition amplitudes for 4d Lorentzian quan…

An analysis of sensor selection for fruit picking with suction-based grippers

Eva Krueger, Marcus Rosette, Joseph R. Davidson · 2026

Robotic fruit harvesting often fails to reliably detect whether a fruit has been successfully picked, limiting efficiency and increasing crop damage. This problem is difficult due to compliant fruit a…

The Quasisymmetric Grassmannian

Nantel Bergeron, Lucas Gagnon, Hunter Spink, Vasu Tewari · 2026

We construct a complex of toric varieties we call the quasisymmetric Grassmannian inside the Grassmannian of $r$-planes in $\mathbb{C}^n$. Each irreducible component is a positroid variety and an $S_n…
