ShareChat: A Dataset of Chatbot Conversations in the Wild
Yueru Yan, Tuc Nguyen, Bo Su +2
By evaluating Large Language Models (LLMs) through uniform, text-only interfaces, current academic benchmarks obscure how the unique designs and affordances of distinct commercial…
Flying Trot Control Method for Quadruped Robot Based on Trajectory Planning
Hongge Wang, Hui Chai, Bin Chen +3
An intuitive control method for the flying trot, which combines offline trajectory planning with real-time balance control, is presented. The motion features of running animals in…
Orientations of -Edge-Connected Planar Multigraphs and Applications
Daniel W. Cranston, Jiaao Li, Bo Su +2
A graph is called strongly -connected if for each boundary function with , there exists an orientat…
Instructional Prompt Optimization for Few-Shot LLM-Based Recommendations on Cold-Start Users
Haowei Yang, Yushang Zhao, Sitao Min +3
The cold-start user issue further compromises the effectiveness of recommender systems in limiting access to the historical behavioral information. It is an effective pipeline to o…
Persistence of Monoclinic Crystal Structure in Three-Dimensional Second-Order Topological Insulator Candidate 1T'-MoTe2 Thin Flake without Structural Phase transition
Bo Su, Yuan Huang, Yan Hui Hou +8
A van der Waals material, MoTe2 with a monoclinic 1T' crystal structure is a candidate for three-dimensional (3D) second-order topological insulators (SOTIs) hosting gapless hinge…
Reconfiguration of Nowhere-zero Flows
Daniel W. Cranston, Jiaao Li, Bo Su +2
Fix an abelian group , a graph , and nowhere-zero -flows and on . Now and are \emph{-flow-adjacent} if there exists a cycle in such tha…
Deep Reinforcement Learning in Autonomous Car Path Planning and Control: A Survey
Yiyang Chen, Chao Ji, Yunrui Cai +2
Combining data-driven applications with control systems plays a key role in recent Autonomous Car research. This thesis offers a structured review of the latest literature on Deep…
Characterization of strongly -connected graphs of small order
Jiaao Li, Bo Su, Zhouningxin Wang +1
A graph is strongly -connected if for each boundary function with for every vertex and $\sum_{v \in V(G)} β…
High-Dimensional -Normed Flows
Chenxing Li, Jiaao Li, Rong Luo +1
We generalize Tutte's integer flows and the -dimensional Euclidean flows of Mattiolo, Mazzuoccolo, RajnÃk, and Tabarelli to \emph{-dimensional -normed nowhere-zero flows}…
Strong and Tunable Electrical-Anisotropy in Type-II Weyl Semimetal Candidate WP2 with Broken Inversion Symmetry
Bo Su, Yanpeng Song, Yanhui Hou +7
A transition metal diphosphide WP2 is a candidate for type-II Weyl semimetals (WSMs) in which spatial inversion symmetry is broken and Lorentz invariance is violated. As one of the…
Strong nonlinear optical response and transient symmetry switching in Type-II Weyl semimetal -WP2
Tianchen Hu, Bo Su, Liyu Shi +13
The topological Weyl semimetals with peculiar band structure exhibit novel nonlinear optical enhancement phenomena even for light at optical wavelengths. While many intriguing nonl…
Highly anisotropic Drude-weight-reduction and enhanced linear-dichroism in van der Waals Weyl semimetal Td-MoTe2 with coherent interlayer electronic transport
Bo Su, Weikang Wu, Jianzhou Zhao +8
Weyl semimetal (WSM) states can be achieved by breaking spatial-inversion symmetry or time reversal symmetry. However, the anisotropy of the energy reduction contributing to the em…
Strongly Anisotropic Charge Dynamics in La3Ni2O7 with Coherent-to-Incoherent Crossover of Interlayer Charge Dynamics
Bo Su, Chaoxin Huang, Jianzhou Zhao +4
We report an optical spectroscopy study of the charge-dynamics anisotropy in the La3Ni2O7 single crystals with the electric field of the incident light parallel to the crystalline…
PreUnlearn: Auditing Collateral Knowledge Damage Before Large Language Model Unlearning
Bo Su, Ankit Shah, Thai Le
Machine unlearning for large language models (LLMs) aims to remove specified knowledge while preserving the rest of the model's capabilities. However, the boundary between knowledg…
Tightly-bound and room-temperature-stable excitons in van der Waals degenerate-semiconductor Bi4O4SeCl2 with high charge-carrier density
Yueshan Xu, Junjie Wang, Bo Su +9
Excitons, which represent a type of quasi-particles consisting of electron-hole pairs bound by the mutual Coulomb interaction, were often observed in lowly-doped semiconductors or…
