This paper reports observation an arc-like structure to north Ab and part circumstellar that is noticeable Aa extending distance 28 AU primary star. The speckle noise constrains its radius <13 AU. Based on size...
Large inner dust gaps in transition disks are frequently posited as evidence of giant planets sculpting gas and the disk, or opening a gap by photoevaporative winds. Although former hypothesis is strongly supported observations deep depletions within some disks, many T Tauri stars hosting accrete at rates typical for an undepleted raising question how occurs these objects. We thus present analysis structure disk around star DM Tau, which accreting ($\sim 10^{-8.3}~\mathrm{M}_\odot~...

Recent advancements in natural language and Large Language Models (LLMs) have enabled AI agents to simulate human-like interactions within virtual worlds. However, these still face limitations complexity flexibility, particularly scenarios involving multiple characters novel objects. Pre-defining all interactable objects the agent's world model presents challenges, conveying implicit intentions through complex remains difficult. To address issues, we propose integrating Game Masters (GMs)...

Crescent-like asymmetric dust structures discovered in protoplanetary disks indicate aggregations. Thus, the research on them helps us understand planet formation process. Here we analyze ALMA data of disk around T-Tauri star SR 21, which has detected previous sub-millimeter observations. Imaged at Band 6 (1.3 mm) with a spatial resolution about 0.$\arcsec$04, is found to consist two rings and three structures, being same ring. Compared image, 3 (2.7 image also shows but some clumps.

The SR24 multi-star system hosts both circumprimary and circumsecondary disks, which are strongly misaligned from each other. disk is circumbinary in nature. Interestingly, disks interacting, they possibly rotate opposite directions. To investigate the nature of this unique twin system, we present 0.''1 resolution near-infrared polarized intensity images circumstellar structures around SR24, obtained with HiCIAO mounted on Subaru 8.2 m telescope. Both resolved have elongated features. While...
Abstract People lose tens of billions dollars a year to financial exploitation in the United States alone. Few studies have examined how preferences for trust and fairness economic activities may contribute risk exploitation. Furthermore, few interaction between factors. In three studies, we attempt address these gaps by surveying 1918 demographically socioeconomically diverse participants examine putative factors self-reported We focused on: 1) others during games are associated with...
This paper presents Invariant Score Distillation (ISD), a novel method for high-fidelity text-to-3D generation. ISD aims to tackle the over-saturation and over-smoothing problems in Sampling (SDS). In this paper, SDS is decoupled into weighted sum of two components: reconstruction term classifier-free guidance term. We experimentally found that stems from large scale comes To overcome these problems, utilizes an invariant score derived DDIM sampling replace SDS. operation allows utilization...
Large Language Models (LLMs) have demonstrated their ability to replicate human behaviors across a wide range of scenarios. However, capability in handling complex, multi-character social interactions has yet be fully explored, primarily due the absence robust, quantitative evaluation methods. This gap slowed development agents proficient more nuanced beyond simple exchanges, for example, small talk. To address this challenge, we introduce Multi-Agent Interaction Evaluation Framework...
