Mid-Infrared Spectral Indicators of Star-Formation and AGN Activity in Normal Galaxies
Marie Treyer, Ben Johnson, David Schiminovich +1
We investigate the use of mid-infrared PAH bands, continuum and emission lines as probes of star-formation and AGN activity in a sample of 100 `normal' and local (z~0.1) galaxies.…
The Nitrogen Budget of Earth
Ben Johnson, Colin Goldblatt
We comprehensively compile and review N content in geologic materials to calculate a new N budget for Earth. Using analyses of rocks and minerals in conjunction with N-Ar geochemis…
Query-efficient model evaluation using cached responses
Hayden Helm, Ben Johnson, Carey Priebe
Evaluating a new model on an existing benchmark is often necessary to understand its behavior before deployment. For modern evaluation frameworks, generating and evaluating a respo…
Gotta match 'em all: Solution diversification in graph matching matched filters
Zhirui Li, Ben Johnson, Daniel L. Sussman +2
We present a novel approach for finding multiple noisily embedded template graphs in a very large background graph. Our method builds upon the graph-matching-matched-filter techniq…
COVID-19 Kaggle Literature Organization
Maksim Ekin Eren, Nick Solovyev, Edward Raff +2
The world has faced the devastating outbreak of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), or COVID-19, in 2020. Research in the subject matter was fast-tracked…
Bounds for maximum likelihood regular and non-regular DoA estimation in -distributed noise
Yuri Abramovich, Olivier Besson, Ben Johnson
We consider the problem of estimating the direction of arrival of a signal embedded in -distributed noise, when secondary data which contains noise only are assumed to be availa…
