Relaxation to nonequilibrium

arXiv · 2026 · English · arXiv

We describe the structure of relaxation for a steadily driven macroscopic body. The time-evolution is characterized as the zero-cost flow for a nonequilibrium and nonlinear extension of the Onsager-Machlup action governing the dynamical fluctuations. The approach hinges on two main elements: the…

Alfvén wave propagation in the partially ionized lower solar atmosphere: a test of the single-fluid approximation

Soler, Roberto

arXiv · 2026 · English · arXiv

Alfvén waves are widely believed to play an important role in the transport of energy from the solar photosphere to the corona through the partially ionized chromosphere. In previous work, the properties of torsional Alfvén waves were theoretically studied using a multi-fluid model. Here, we…

RANGER: Sparsely-Gated Mixture-of-Experts with Adaptive Retrieval Re-ranking for Pathology Report Generation

Chen, Yixin; Su, Ziyu; Khan, Hikmat et al.

arXiv · 2026 · English · arXiv

Pathology report generation remains a relatively under-explored downstream task, primarily due to the gigapixel scale and complex morphological heterogeneity of Whole Slide Images (WSIs). Existing pathology report generation frameworks typically employ transformer architectures, relying on a…

Coexistence of Chromatic Flares and an Achromatic QPO in the Gamma-ray Blazar PG 1553+113

Madero, Elena; Domínguez, Alberto

arXiv · 2026 · English · arXiv

The physical origin of quasi-periodic oscillations (QPOs) in blazars remains debated, with geometric and plasma-driven scenarios as the main competing interpretations. Discriminating between them requires probing variability beyond flux periodicity. We study the spectral evolution of the BL Lac…

Design, Mapping, and Contact Anticipation with 3D-printed Whole-Body Tactile and Proximity Sensors

Kohlbrenner, Carson; Soukhovei, Anna; Escobedo, Caleb et al.

arXiv · 2026 · English · arXiv

Robots operating in dynamic and shared environments benefit from anticipating contact before it occurs. We present GenTact-Prox, a fully 3D-printed artificial skin that integrates tactile and proximity sensing for contact detection and anticipation. The artificial skin platform is modular in…

Integrated cooperative localization of heterogeneous measurement swarm: A unified data-driven method

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…

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…
