Experimental Evidence of Amplitude-Dependent Surface Wave Dispersion via Nonlinear Contact Resonances

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Setare Hajarolasvadi, Paolo Celli, Brian L. Kim, Ahmed E. Elbanna, Chiara Daraio | Summary: In this letter, we provide an experimental demonstration of amplitude-dependent dispersion tuning of surface acoustic waves interacting with nonlinear resonators. Leveraging the similarity between the dispersion properties of plate edge waves and surface […]

Using Electron Energy-Loss Spectroscopy to Measure Nanoscale Electronic and Vibrational Dynamics in a TEM

Posted by klaurent Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ye-Jin Kim, Levi D. Palmer, Wonseok Lee, Nicholas J. Heller, Scott K. Cushing | Summary: Electron energy-loss spectroscopy (EELS) can simultaneously measure similar information to X-ray, UV-Vis, and IR spectroscopies but in one instrument with atomic resolution. To date, EELS in a transmission electron microscope (TEM) […]

Enhancing Clinical Evidence Recommendation with Multi-Channel Heterogeneous Learning on Evidence Graphs

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | Authors: Maolin Luo, Xiang Zhang | Summary: Clinical evidence encompasses the associations and impacts between patients, interventions (such as drugs or physiotherapy), problems, and outcomes. The goal of recommending clinical evidence is to provide medical practitioners with relevant information to support their decision-making processes and to generate new evidence. Our […]

Action Pick-up in Dynamic Action Space Reinforcement Learning

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | Authors: Jiaqi Ye, Xiaodong Li, Pangjing Wu, Feng Wang | Summary: Most reinforcement learning algorithms are based on a key assumption that Markov decision processes (MDPs) are stationary. However, non-stationary MDPs with dynamic action space are omnipresent in real-world scenarios. Yet problems of dynamic action space reinforcement learning have been […]

A Hierarchical Multi-Vehicle Coordinated Motion Planning Method based on Interactive Spatio-Temporal Corridors

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | Authors: Xiang Zhang, Boyang Wang, Yaomin Lu, Haiou Liu, Jianwei Gong, Huiyan Chen | Summary: Multi-vehicle coordinated motion planning has always been challenged to safely and efficiently resolve conflicts under non-holonomic dynamic constraints. Constructing spatial-temporal corridors for multi-vehicle can decouple the high-dimensional conflicts and further reduce the difficulty of obtaining […]

Weakly-Supervised Text-driven Contrastive Learning for Facial Behavior Understanding

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Taoyue Wang, Xiaotian Li, Huiyuan Yang, Lijun Yin | Summary: Contrastive learning has shown promising potential for learning robust representations by utilizing unlabeled data. However, constructing effective positive-negative pairs for contrastive learning on facial behavior datasets remains challenging. This is because such pairs inevitably encode […]
