ROLO-SLAM: Rotation-Optimized LiDAR-Only SLAM in Uneven Terrain with Ground Vehicle

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yinchuan Wang, Bin Ren, Xiang Zhang, Pengyu Wang, Chaoqun Wang | Summary: LiDAR-based SLAM is recognized as one effective method to offer localization guidance in rough environments. However, off-the-shelf LiDAR-based SLAM methods suffer from significant pose estimation drifts, particularly components relevant to the vertical direction, when passing […]

SDPO: Segment-Level Direct Preference Optimization for Social Agents

Kavli Affiliate: Ke Wang | First 5 Authors: Aobo Kong, Wentao Ma, Shiwan Zhao, Yongbin Li, Yuchuan Wu | Summary: Social agents powered by large language models (LLMs) can simulate human social behaviors but fall short in handling complex goal-oriented social dialogues. Direct Preference Optimization (DPO) has proven effective in aligning LLM behavior with human […]

Enhanced Condensation Through Rotation

Kavli Affiliate: Frank Wilczek | First 5 Authors: Maxim Chernodub, Frank Wilczek, , , | Summary: We argue that the rotation of a thin superconducting cylinder can increase the critical temperature of the superconducting phase transition substantially. The phenomenon can be interpreted as an effective negative moment of inertia associated with condensation of Cooper pairs. […]

Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Christos Panagiotou, William N. Alston, Joheen Chakraborty | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), […]

FEASTS: Radial Distribution of HI surface densities down to 0.01 M$_{odot}$ pc$^{-2}$ of 35 Nearby Galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Dong Yang, Xuchen Lin, Qifeng Huang, Zhijie Qu | Summary: We present the HI surface density ($Sigma_{rm HI}$) radial distributions based on total-power HI images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72 degree. We derive the HI […]
