Computer-aided pathology detection algorithms for video-based imaging modalities must accurately interpret complex spatiotemporal information by integrating findings across multipl…
Soft X-Ray Observations of Quiescent Solar Active Regions using Novel Dual-zone Aperture X-ray Solar Spectrometer (DAXSS)
Bennet D. Schwab, Robert H. A. Sewell, Thomas N. Woods +3
The Dual-zone Aperture X-ray Solar Spectrometer (DAXSS) was flown on 2018 June18 on the NASA 36.336 sounding rocket flight and obtained the highest resolution to date for solar sof…
Trigonometric functions in the -norm
Sunil Chebolu, Andrew Hatfield, Riley Klette +2
Trigonometry is the study of circular functions, which are functions defined on the unit circle , where distances are measured using the Euclidean norm. When distances…
Modeling tsunammi inundation for hazard assessment of the Coral Coast of Fiji: Communities of Sigatoka and Cuvu
Diego Arcas, Christopher Moore
A tsunami hazard assessment was conducted for the communities of Sigatoka and Cuvu, located on the island of Viti Levu, Fiji. The study presents an overview of historical seismic a…
Quantum Electrodynamic Corrections to Cyclotron States in a Penning Trap
Ulrich D. Jentschura, Christopher Moore
We analyze the leading and higher-order quantum electrodynamic corrections to the energy levels for a single electron bound in a Penning trap, including the Bethe logarithm correct…
Ultrasound Image Synthesis Using Generative AI for Lung Ultrasound Detection
Yu-Cheng Chou, Gary Y. Li, Li Chen +15
Developing reliable healthcare AI models requires training with representative and diverse data. In imbalanced datasets, model performance tends to plateau on the more prevalent cl…
Kitaev chain with a quantum dot
Chuanchang Zeng, Christopher Moore, Apparao M. Rao +2
We solve analytically the problem of a finite length Kitaev chain coupled to a quantum dot (QD), which extends the standard Kitaev chain problem making it more closely related to t…
Supra-arcade downflows in an extensive fan associated with a giant quiescent solar filament eruption
Xiaoyan Xie, Katharine Reeves, Chengcai Shen +6
We investigate the aftermath of a giant quiescent solar filament eruption on December 24, 2023. One feature of the eruption is an extensive fan above the filament channel that is a…
Quasi-periodic pulsations in solar flares: a key diagnostic of energy release on the Sun
Andrew Inglis, Laura Hayes, Silvina Guidoni +18
Solar flares are among the most powerful and disruptive events in our solar system, however the physical mechanisms driving and transporting this energetic release are not fully un…
Disks in a narrow channel jammed by gravity and centrifuge: profiles of pressure, mass density and entropy density
Christopher Moore, Dan Liu, Benjamin Ballnus +2
This work investigates jammed granular matter under conditions that produce heterogeneous mass distributions on a mesoscopic scale. We consider a system of identical disks that are…
Miniature X-Ray Solar Spectrometer (MinXSS) - A Science-Oriented, University 3U CubeSat
James P. Mason, Thomas N. Woods, Amir Caspi +7
The Miniature X-ray Solar Spectrometer (MinXSS) is a 3-Unit (3U) CubeSat developed at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, Boulder…
Analytical Solution to the Kronig-Penney Model with Harmonic Oscillator Wells: Insights to Tight-Binding
Christopher Moore, Frank Marsiglio
The celebrated Kronig-Penney model traditionally has been formulated with square well potentials representing atomic centres. Here, we use a slightly more realistic potential, the…
Nernst effect in Dirac and inversion-asymmetric Weyl semimetals
Gargee Sharma, Christopher Moore, Subhodip Saha +1
Dirac semimetals are three dimensional analog of graphene with massless Dirac fermions as low energy electronic excitations. In contrast to Weyl semimetals, the point nodes in the…
