Visualizing Local Maxima of the Ohio overdose epidemic with Vineyards
Nicholas Bermingham, David White, Nathan Willey
Understanding how spatial patterns evolve over time is a complex task that often arises in the analysis of public health data. In this work, we investigate the use of vineyards fro…
Approximation theorems in bilipschitz invariant theory
Jameson Cahill, Joseph W. Iverson, Dustin G. Mixon +1
Bilipschitz invariant theory concerns low-distortion embeddings of orbit spaces into Euclidean space. To date, embeddings with the smallest-possible distortion are known for only a…
Towards the Composition of sub-PeV Cosmic Rays at IceCube
Julian Saffer
With the implementation of a low-energy trigger, the surface array of the IceCube Neutrino Observatory is able to record cosmic-ray induced air showers with a primary energy of a f…
Tracking the Spatiotemporal Spread of the Ohio Overdose Epidemic with Topological Data Analysis
Nicholas Bermingham, David White, Nathan Willey
In recent years, techniques from Topological Data Analysis (TDA) have proven effective at capturing spatial features of multidimensional data. However, applying TDA to spatiotempor…
Cosmic Ray Detection with the IceTop Enhancement
Megha Venugopal
IceTop is the cosmic-ray detector located on the surface of the IceCube Neutrino Observatory at the South Pole, consisting of 81 pairs of ice-Cherenkov tanks. The rise in the energ…
