Linear analysis of I-C-Love universal relations for neutron stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Zexin Hu, Yong Gao, Lijing Shao, , | Summary: Neutron stars (NSs) are excellent laboratories for testing gravity theories as they are strongly self-gravitating bodies and have rich observational phenomena. However, strong-gravity effects in NS could be degenerate with their equation of state (EOS) which is largely […]

SuperCoder: Assembly Program Superoptimization with Large Language Models

Kavli Affiliate: Ke Wang | First 5 Authors: Anjiang Wei, Anjiang Wei, , , | Summary: Superoptimization is the task of transforming a program into a faster one while preserving its input-output behavior. In this work, we investigate whether large language models (LLMs) can serve as superoptimizers, generating assembly programs that outperform code already optimized […]

AGN star dynamics under the Influence of Outflow-Ambient Interactions

Kavli Affiliate: Lile Wang | First 5 Authors: Muxin Liu, Lile Wang, Peng Peng, , | Summary: Stars with outflows interacting with ambient gas experience accelerations arising from the gravitational feedback induced by the interaction structure. In this work, three-dimensional (3D) local shearing box simulations are performed to investigate the dynamical evolution of a star […]

WeGA: Weakly-Supervised Global-Local Affinity Learning Framework for Lymph Node Metastasis Prediction in Rectal Cancer

Kavli Affiliate: Feng Yuan | First 5 Authors: Yifan Gao, Yaoxian Dong, Wenbin Wu, Chaoyang Ge, Feng Yuan | Summary: Accurate lymph node metastasis (LNM) assessment in rectal cancer is essential for treatment planning, yet current MRI-based evaluation shows unsatisfactory accuracy, leading to suboptimal clinical decisions. Developing automated systems also faces significant obstacles, primarily the […]

Origin of the ring ellipticity in the black hole images of M87*

Kavli Affiliate: Feng Yuan | First 5 Authors: Rohan Dahale, Ilje Cho, Kotaro Moriyama, Kaj Wiik, Paul Tiede | Summary: We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of the […]

Shared Properties of Merger-driven Long-duration Gamma-Ray Bursts

Kavli Affiliate: Zhuo Li | First 5 Authors: Yacheng Kang, Jin-Ping Zhu, Yu-Han Yang, Ziming Wang, Eleonora Troja | Summary: The recent detections of bright optical/infrared kilonova signals following two long-duration gamma-ray bursts (LGRBs), GRB 211211A and GRB 230307A, have significantly challenged the traditional classification of GRBs. These merger-driven LGRBs may represent a distinct GRB […]
