How to See Hidden Patterns in Metamaterials with Interpretable Machine Learning

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Zhi Chen, Alexander Ogren, Chiara Daraio, L. Catherine Brinson, Cynthia Rudin | Summary: Metamaterials are composite materials with engineered geometrical micro- and meso-structures that can lead to uncommon physical properties, like negative Poisson’s ratio or ultra-low shear resistance. Periodic metamaterials are composed of repeating unit-cells, and geometrical […]

COMAP Early Science: IV. Power Spectrum Methodology and Results

Posted by dbos Stanford

Kavli Affiliate: Sarah E. Church | First 5 Authors: Håvard T. Ihle, Jowita Borowska, Kieran A. Cleary, Hans Kristian Eriksen, Marie K. Foss | Summary: We present the power spectrum methodology used for the first-season COMAP analysis, and assess the quality of the current data set. The main results are derived through the Feed-feed Pseudo-Cross-Spectrum […]

Very-High Dynamic Range, 10,000 frames/second Pixel Array Detector for Electron Microscopy

Posted by dbos Cornell

Kavli Affiliate: Sol M. Gruner | First 5 Authors: Hugh T. Philipp, Mark W. Tate, Katherine S. Shanks, Luigi Mele, Maurice Peemen | Summary: Precision and accuracy of quantitative scanning transmission electron microscopy (STEM) methods such as ptychography, and the mapping of electric, magnetic and strain fields depend on the dose. Reasonable acquisition time requires […]
