     Ze, Kunrui; Wang, Wei; Sun, Guibin et al.

     arXiv · 2026 · English · arXiv

     The cooperative localization (CL) problem in heterogeneous robotic systems with different measurement capabilities is investigated in this work. In practice, heterogeneous sensors lead to directed and sparse measurement topologies, whereas most existing CL approaches rely on multilateral…

     Retrieval-Augmented Generation with Covariate Time Series

     Liang, Kenny Ye; Pei, Zhongyi; Zhang, Huan et al.

     arXiv · 2026 · English · arXiv

     While RAG has greatly enhanced LLMs, extending this paradigm to Time-Series Foundation Models (TSFMs) remains a challenge. This is exemplified in the Predictive Maintenance of the Pressure Regulating and Shut-Off Valve (PRSOV), a high-stakes industrial scenario characterized by (1) data scarcity…

     Uncertainty and Autarky: Cooperative Game Theory for Stable Local Energy Market Partitioning

     Vaishampayan, Saurabh; Kamgarpour, Maryam

     arXiv · 2026 · English · arXiv

     Local energy markets empower prosumers to form coalitions for energy trading. However, the optimal partitioning of the distribution grid into such coalitions remains unclear, especially in constrained grids with stochastic production and consumption. This analysis must take into account the…

     Network Design for Wafer-Scale Systems with Wafer-on-Wafer Hybrid Bonding

     Iff, Patrick; Bonato, Tommaso; Besta, Maciej et al.

     arXiv · 2026 · English · arXiv

     Transformer-based large language models are increasingly constrained by data movement as communication bandwidth drops sharply beyond the chip boundary. Wafer-scale integration using wafer-on-wafer hybrid bonding alleviates this limitation by providing ultra-high bandwidth between reticles on…

     The People's Gaze: Co-Designing and Refining Gaze Gestures with General Users and Gaze Interaction Experts

     Lei, Yaxiong; Gong, Xinya; He, Shijing et al.

     arXiv · 2026 · English · arXiv

     As eye-tracking becomes increasingly common in modern mobile devices, the potential for hands-free, gaze-based interaction grows, but current gesture sets are largely expert-designed and often misaligned with how users naturally move their eyes. To address this gap, we introduce a two-phase…

     Ecosystem Trust Profiles

     Strnadl, Christoph F.

     arXiv · 2026 · English · arXiv

     We define a method how digital ecosystems (including data spaces) may autonomously define and "advertise" credentials they issue or they trust in the form of so-called ecosystem trust profiles. An ecosystem trust profile collects all (verifiable) credentials and issuers sorted by trust scope…

     Spectral Gaps and Spatial Priors: Studying Hyperspectral Downstream Adaptation Using TerraMind

     Leonardi, Julia Anna; Jakubik, Johannes; Fraccaro, Paolo et al.

     arXiv · 2026 · English · arXiv

     Geospatial Foundation Models (GFMs) typically lack native support for Hyperspectral Imaging (HSI) due to the complexity and sheer size of high-dimensional spectral data. This study investigates the adaptability of TerraMind, a multimodal GFM, to address HSI downstream tasks \emph{without}…

     SODA: Sensitivity-Oriented Dynamic Acceleration for Diffusion Transformer

     Shao, Tong; Fu, Yusen; Sun, Guoying et al.

     arXiv · 2026 · English · arXiv

     Diffusion Transformers have become a dominant paradigm in visual generation, yet their low inference efficiency remains a key bottleneck hindering further advancement. Among common training-free techniques, caching offers high acceleration efficiency but often compromises fidelity, whereas pruning…

     Bistability of electron temperature in atomically thin semiconductors in the presence of exciton photogeneration

     Shentsev, A. M.

     arXiv · 2026 · English · arXiv

     We study the dynamic equilibrium between trions and excitons in monolayers of transition metal dichalcogenides in the presence of resident charge carriers and continuous photogeneration of excitons. We show that heating of the system via Drude absorption of low-frequency radiation leads to…

     LiveWorld: Simulating Out-of-Sight Dynamics in Generative Video World Models

     Duan, Zicheng; Xia, Jiatong; Zhang, Zeyu et al.

     arXiv · 2026 · English · arXiv

     Recent generative video world models aim to simulate visual environment evolution, allowing an observer to interactively explore the scene via camera control. However, they implicitly assume that the world only evolves within the observer's field of view. Once an object leaves the observer's view…

     Optimize discrete loss with finite-difference physics constraint and time-stepping for PDE solving

     Luo, Yali; Zou, Yiye; Zhang, Heng et al.

     arXiv · 2026 · English · arXiv

     Computational Fluid Dynamics (CFD) is an important approach for analyzing flow phenomena and predicting engineering-relevant quantities. The governing physics is formulated as partial differential equations(PDEs) and solved numerically on computational grids. Physics-informed neural networks(PINNs)…

     Physical mechanisms of ohmic contact and tunnel diode: A novel explanation in terms of impurity-photovoltaic-effect resulting from infrared self-emission at room-temperature

     Li, Jianming

     arXiv · 2026 · English · arXiv

     A mechanism of quantum-mechanical tunneling is based on electron-wavefunction and is used to explain ohmic contact as well as tunnel and Zener diodes. Tunneling is the important example of wave-particle duality. In this study, an attempt is made to explain these devices in particle description. As…

     ACCURATE: Arbitrary-shaped Continuum Reconstruction Under Robust Adaptive Two-view Estimation

     Zhang, Yaozhi; Yu, Shun; Zhang, Yugang et al.

     arXiv · 2026 · English · arXiv

     Accurate reconstruction of arbitrary-shaped long slender continuum bodies, such as guidewires, catheters and other soft continuum manipulators, is essential for accurate mechanical simulation. However, existing image-based reconstruction approaches often suffer from limited accuracy because they…

     GazeShift: Unsupervised Gaze Estimation and Dataset for VR

     Shapira, Gil; Goldin, Ishay; Artyomov, Evgeny et al.

     arXiv · 2026 · English · arXiv

     Gaze estimation is instrumental in modern virtual reality (VR) systems. Despite significant progress in remote-camera gaze estimation, VR gaze research remains constrained by data scarcity, particularly the lack of large-scale, accurately labeled datasets captured with the off-axis camera…

     Kumar, Bhavesh; Feng, Dylan; Tang, Leonard

     arXiv · 2026 · English · arXiv

     Multimodal judges struggle to ground decisions in visual evidence. We present MJ1, a multimodal judge trained with reinforcement learning that enforces visual grounding through a structured grounded verification chain (observations $\rightarrow$ claims $\rightarrow$ verification $\rightarrow$…

     Shen, Junyu; She, Zhendong; Zhang, Chenghanyu et al.

     arXiv · 2026 · English · arXiv

     The paradigm of Multimodal Large Language Models (MLLMs) offers a promising blueprint for advancing the electromagnetic (EM) domain. However, prevailing approaches often deviate from the native MLLM paradigm, instead using task-specific or pipelined architectures that lead to fundamental…

     Where, What, Why: Toward Explainable 3D-GS Watermarking

     Cai, Mingshu; Li, Jiajun; Yoshie, Osamu et al.

     arXiv · 2026 · English · arXiv

     As 3D Gaussian Splatting becomes the de facto representation for interactive 3D assets, robust yet imperceptible watermarking is critical. We present a representation-native framework that separates where to write from how to preserve quality. A Trio-Experts module operates directly on Gaussian…

     A Survey of Reinforcement Learning For Economics

     Rawat, Pranjal

     arXiv · 2026 · English · arXiv

     This survey (re)introduces reinforcement learning methods to economists. The curse of dimensionality limits how far exact dynamic programming can be effectively applied, forcing us to rely on suitably "small" problems or our ability to convert "big" problems into smaller ones. While this reduction…
