Active Solids: Defect Self-Propulsion Without Flow

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Fridtjof Brauns, Myles O’Leary, Arthur Hernandez, Mark J. Bowick, M. Cristina Marchetti | Summary: The self-propulsion of +1/2 topological defects is a hallmark of active nematic fluids, where the defects are advected by the flow field they themselves generate. In this paper we propose a minimal […]

A vector-based strategy for olfactory navigation in Drosophila

Kavli Affiliate: Vanessa Ruta | Authors: Andrew F. Siliciano, Sun Minni, Chad Morton, Charles K. Dowell, Noelle B. Eghbali, Juliana Y. Rhee, L. F. Abbott and Vanessa Ruta | Summary: Odors serve as essential cues for navigation. Although tracking an odor plume has been modeled as a reflexive process, it remains unclear whether animals can […]

Imaging current flow and injection in scalable graphene devices through NV-magnetometry

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Kaj Dockx, Michele Buscema, Saravana Kumar, Tijmen van Ree, Abbas Mohtashami | Summary: The global electronic properties of solid-state devices are strongly affected by the microscopic spatial paths of charge carriers. Visualising these paths in novel devices produced by scalable processes would provide a quality […]

Simplify RLHF as Reward-Weighted SFT: A Variational Method

Kavli Affiliate: Zhuo Li | First 5 Authors: Yuhao Du, Zhuo Li, Pengyu Cheng, Zhihong Chen, Yuejiao Xie | Summary: Reinforcement Learning from Human Feedback (RLHF) is crucial for aligning Large Language Models (LLMs) with human values. However, RLHF has been continuously challenged by its high complexity in implementation and computation consumption. Even with recent […]

Systematic study of the composition of Type I X-ray burst ashes: Neutron star structure v.s. Reaction rate uncertainties

Kavli Affiliate: Renxin Xu | First 5 Authors: Guoqing Zhen, Helei Liu, Akira Dohi, Guoliang Lü, Nobuya Nishimura | Summary: In this study, we calculate for the first time the impacts of neutron star(NS) structure on the type I X-ray burst ashes using the texttt{MESA} code. We find an increased mass fraction of the heavier […]

Estimation of Treatment Effects based on Kernel Matching

Kavli Affiliate: Wei Gao | First 5 Authors: Chong Ding, Zheng Li, Hon Keung Tony Ng, Wei Gao, | Summary: The treatment effect represents the average causal impact or outcome difference between treatment and control groups. Treatment effects can be estimated through social experiments, regression models, matching estimators, and instrumental variables. In this paper, we […]
