A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
Direct Optimization of Stellarator Omnigenity from the Second Adiabatic Invariant
Hanlin Chen, Zhiyuan Lu, Guosheng Xu +4
Stellarators offer a steady-state, disruption-free path to fusion energy but suffer from enhanced particle losses due to their three-dimensional geometry. Existing optimization met…
What to Remove, What to Preserve: Dual-Ambiguity Rectification for All-in-One Image Restoration
Cencen Liu, Wen Yin, Dongyang Zhang +6
The paper introduces DAR-Net, a deep network that tackles the dual ambiguity problem in all‑in‑one image restoration by modeling degradation states with a simplex‑constrained arche…
Beyond Borrowed Histories: Person-Aligned User Simulation for Interactive Role-Playing Evaluation
Yuhang Zhu, Mingxuan Du, Benfeng Xu +3
The paper presents PALATE, a benchmark that uses per‑user simulated agents to evaluate role‑playing language models through free‑form, multi‑turn conversations and personalized sat…
IMFuse: Instance-Aware Multi-Layer Fusion for LLM-Enhanced Sequential Recommendation
Yuheng Zheng, Yu Cui, Bin Wu +4
The paper introduces IMFuse, a method that adaptively combines representations from multiple layers of large language models to improve sequential recommendation, using instance-aw…
The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster
Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51
The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…
