Kavli Affiliate: Jing Wang | First 5 Authors: Mengmeng Zhang, Xingyuan Dai, Yicheng Sun, Jing Wang, Yueyang Yao | Summary: Although the Segment Anything Model (SAM) is highly effective in natural image segmentation, it requires dependencies on prompts, which limits its applicability to medical imaging where manual prompts are often unavailable. Existing efforts to fine-tune […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Santanu Mondal, Gourab Giri, Ravi Joshi, Paul J. Wiita, Gopal-Krishna | Summary: Our understanding of large-scale radio jets in merger systems has been drastically improved in the era of VLA, VLBA/EVN, uGMRT, and MeerKAT. Twin Radio Galaxies (TRGs) are the rare interacting galaxy pairs where both […]
Kavli Affiliate: Xuebing Wu | Summary:Emission Line Galaxies (ELGs) are crucial for cosmological studies, particularly in understanding the large-scale structure of the Universe and the role of dark energy. ELGs form an essential component of the target catalogue for the Dark Energy Spectroscopic Instrument (DESI), a major astronomical survey. However, the accurate selection of ELGs […]
Kavli Affiliate: Jing Wang | First 5 Authors: Zhoufaran Yang, Zhoufaran Yang, , , | Summary: Visual texts embedded in videos carry rich semantic information, which is crucial for both holistic video understanding and fine-grained reasoning about local human actions. However, existing video understanding benchmarks largely overlook textual information, while OCR-specific benchmarks are constrained to […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kejian Chen, Zhengrong Li, Kohei Inayoshi, Luis C. Ho, | Summary: Little red dots (LRDs), a population of active galactic nuclei (AGNs) recently identified by JWST, are characterized by their compact morphology and red optical continuum emission, which is often interpreted as evidence for significant dust extinction […]
Kavli Affiliate: Luis Ho| First 5 Authors: Kejian Chen, Kejian Chen, , , | Summary:Little red dots (LRDs), a population of active galactic nuclei (AGNs) recently identified by JWST, are characterized by their compact morphology and red optical continuum emission, which is often interpreted as evidence for significant dust extinction of $A_V gtrsim 3$ mag. […]
Kavli Affiliate: Ran Wang | First 5 Authors: Nan Liu, Ran Wang, , , | Summary: We address the long-time asymptotics of the solution to the Cauchy problem of ccSP (coupled complex short pulse) equation on the line for decaying initial data that can support solitons. The ccSP system describes ultra-short pulse propagation in optical […]
Kavli Affiliate: Jing Wang | First 5 Authors: Lei Yu, Yechao Zhang, Ziqi Zhou, Yang Wu, Wei Wan | Summary: With the rapid development of the Vision-Language Model (VLM), significant progress has been made in Visual Question Answering (VQA) tasks. However, existing VLM often generate inaccurate answers due to a lack of up-to-date knowledge. To […]
Kavli Affiliate: Subo Dong | Summary:Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-host stars (HS) and isolated stars (IS) with no detected planets, we analyze a large sample of stars with temperatures ranging from […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Guodong Du, Weiyang Guo, Yigeng Zhou, Xiucheng Li | Summary: Aligning large language models (LLMs) to simultaneously satisfy multiple objectives remains a significant challenge, especially given the diverse and often conflicting nature of human preferences. Existing alignment methods struggle to balance trade-offs effectively, often requiring […]
