Three-dimensional imaging of embedded interfaces with multislice ptychography

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Jianhua Zhang, Cong Su, Salman Kahn, Huaidong Jiang | Summary: We demonstrate the application of multislice ptychography to a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set. The propagation from the top flake, through the interface, to the bottom flake is […]

Three-dimensional imaging of buried heterointerfaces

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Haozhi Sha, Jianhua Zhang, Cong Su, Salman Kahn | Summary: We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We identify the buried heterointerface between two twisted h-BN flakes with a […]

A Transformer-Conditioned Neural Fields Pipeline with Polar Coordinate Representation for Astronomical Radio Interferometric Data Reconstruction

Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Qiong Luo, Feng Wang, , | Summary: In radio astronomy, visibility data, which are measurements of wave signals from radio telescopes, are transformed into images for observation of distant celestial objects. However, these resultant images usually contain both real sources and artifacts, due to signal […]

Federated Semi-Supervised and Semi-Asynchronous Learning for Anomaly Detection in IoT Networks

Kavli Affiliate: Feng Wang | First 5 Authors: Wenbin Zhai, Feng Wang, Liang Liu, Youwei Ding, Wanying Lu | Summary: Existing FL-based approaches are based on the unrealistic assumption that the data on the client-side is fully annotated with ground truths. Furthermore, it is a great challenge how to improve the training efficiency while ensuring […]
