Resilience of Task-Oriented V2X Networks to Incomplete Information Sharing
arXiv:2602.18620v2 Announce Type: replace Abstract: Task-oriented Vehicle-to-Everything (V2X) networks have recently been proposed to scalably support the large-scale deployment of connected vehicles. In task-oriented V2X networks, vehicles select the content of the transmitted messages based on its relevance to the intended receivers. However, estimating relevance can be challenging, especially in highly dynamic and complex driving scenarios.
WristCompass: Kinematic Coupling as a Learnable Visual Concept for Ego-Camera Orientation
arXiv:2605.30671v1 Announce Type: new Abstract: Recovering ego-camera orientation from manipulation video is a prerequisite for disentangling hand motion from camera motion, a key step in imitation learning from egocentric demonstrations. The obvious approach, inferring orientation from scene geometry, fails when hands occlude the frame: VGGT, a 1B-parameter scene reconstruction model, scores worse than a constant predictor on the TACO benchmark. We identify an alternative visual concept...
New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits
New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor deposition (MPCVD). By employing nitrogen-radical selective etching, which simultaneously enhances metal-mask...
Orientation Dependence of R2' in White Matter: Digital Characterization, Modelling and Implications for Studying Brain Physiology
Introduction R2* is the transverse relaxation rate of tissue, influenced by local magnetic field inhomogeneities arising from susceptibility differences. It decomposes into R2 and R2', where R2' is the reversible component most sensitive to blood oxygenation and forms the basis of the BOLD fMRI signal. Although orientation dependence of R2 and R2* in white matter (WM) has been attributed primarily to myelin, the vascular contribution to R2' has not been systematically characterized.
Preferential orientation of slender elastic floaters in gravity waves
arXiv:2604.08323v2 Announce Type: replace Abstract: Slender floaters drifting in propagating gravity waves slowly rotate towards a preferential state of orientation with respect to the angle of incidence. This angular drift arises from a wave-induced, second order mean yaw moment. We develop a diffractionless, hydro-elastic theory to compute this mean yaw moment for a thin, flexible structure whose width and thickness are small compared with the wavelength.
Spatially Distributed Task-Oriented Compression for Multi-Emitter Localization and Characterization with Spectral Overlap
Announce Type: replace-cross Abstract: Radio frequency spectrum awareness requires the ability to detect, localize, and characterize emitters in dense and contested wireless environments. In this work, we propose a task-oriented distributed compression framework for joint multi-emitter localization and characterization using spatially distributed receivers. Each receiver observes a short window of complex IQ samples, converts the observation to a time--frequency representation, and encodes...

The Comparative Trap: How Social Comparison Orientation Drives Problematic Generative AI (GenAI) Use
arXiv:2606.03560v1 Announce Type: new Abstract: Although Generative AI (GenAI) improves task efficiency in the short term, it creates competitive pressures that perpetuate individuals' fear of being eliminated, thereby increasing the risk of problematic use. Existing research has focused on the perspective of individual psychological vulnerability, but has neglected the social comparison context caused by GenAI. This study examines the direct effects of social comparison orientation on...
PAG-Agent: a biologist-oriented research assistant for context-aware pathway-level analysis and interpretation
Pathway analysis is a critical step for translating gene-level omics results into biological mechanisms, yet existing workflows often leave researchers with long lists of statistically significant pathways that are difficult to interpret, validate, and connect to experimental context. We developed PAG-Agent, a biologist-oriented virtual research assistant that integrates pathway-level statistical analysis, context-aware biological interpretation, literature-supported reasoning, and...
Unlocking Proactivity in Task-Oriented Dialogue
arXiv:2605.22240v2 Announce Type: replace Abstract: Proactive task-oriented dialogue (TOD), such as outbound sales, demands a persuasive agent that actively probes the user's concerns and steers the conversation toward acceptance within a bounded number of turns. Yet post-trained LLMs are inherently conservative, and reward-shaping RL (e.g., GRPO) struggles since it only re-weights what an already passive policy samples. We show that conditioning on the user's latent concerns unlocks...
