Enabling remote quantum emission in 2D semiconductors via porous metallic networks
Jose J. Fonseca, Andrew L. Yeats, Brandon Blue +11
The interaction between two-dimensional crystals (2DCs) and metals is ubiquitous in 2D material research. Here we report how 2DC overlayers influence the recrystallization of relat…
Penalized k-means algorithms for finding the correct number of clusters in a dataset
Behzad Kamgar-Parsi, Behrooz Kamgar-Parsi
In many applications we want to find the number of clusters in a dataset. A common approach is to use the penalized k-means algorithm with an additive penalty term linear in the nu…
On the pressure dependence of the thermodynamical scaling exponent gamma
Riccardo Casalini, Timothy C. Ransom
Since its initial discovery more than fifteen years ago, the thermodynamical scaling of the dynamics of supercooled liquids has been used to provide many new important insights in…
Mutual Information and the Edge of Chaos in Reservoir Computers
Thomas L. Carroll
A reservoir computer is a dynamical system that may be used to perform computations. A reservoir computer usually consists of a set of nonlinear nodes coupled together in a network…
Estimating the volume and surface area of air bubbles entrained by breaking waves from whitecap observations: With implications on the characteristic breaking wave speed and breaking strength parameter
Paul A. Hwang
A conceptual model relating the whitecap coverage to the bubble plume buoyancy is developed following the observation that the entrained bubble plume buoyancy constitutes a large p…
Effects of Short Scale Roughness and Wave Breaking Efficiency on Sea Spray Aerosol Production: Multisensor Field Observations
Paul A. Hwang, Ivan B. Savelyev, Steve L. Means +5
Simultaneous measurements of sea spray aerosol (SSA), wind, wave, underwater acoustic noise, and microwave brightness temperature are obtained in the open ocean. These data are ana…
Directional Distribution of Ocean Surface Roughness Observed in Microwave Radar Backscattering
Paul A. Hwang
The directional distribution of ocean surface roughness is examined using the Ku, C and L band microwave radar backscattering. The parameters characterizing the upwind-downwind and…
Variable Spectral Slope and Nonequilibrium Surface Wave Spectrum
Paul A. Hwang
The wave spectral properties in the centimeter to decameter (cmDm) wavelength range is of great interest to ocean remote sensing and studies of ocean surface processes including th…
Bimodal directional propagation of wind-generated ocean surface waves
Paul A. Hwang, David W. Wang, W. Erick Rogers +3
Over the years, the directional distribution functions of wind-generated wave field have been assumed to be unimodal. While details of various functional forms differ, these direct…
Discovery of Soft X-ray Pulsations from PSR J1231-1411 using NICER
Paul S. Ray, Sebastien Guillot, Scott M. Ransom +10
We report the discovery of soft X-ray pulsations from the nearby millisecond pulsar PSR J12311411 using NICER. The pulsed emission is characterized by a broad and asymmetric mai…
Ship classification from overhead imagery using synthetic data and domain adaptation
Chris M. Ward, Josh Harguess, Cameron Hilton
In this paper, we revisit the problem of classifying ships (maritime vessels) detected from overhead imagery. Despite the last decade of research on this very important and pertine…
Quantum-Assisted Clustering Algorithms for NISQ-Era Devices
Samuel S. Mendelson, Robert W. Strand, Guy B. Oldaker +1
In the NISQ-era of quantum computing, we should not expect to see quantum devices that provide an exponential improvement in runtime for practical problems, due to the lack of erro…
The Next Generation Celestial Reference Frame
Megan Johnson, Frank Schinzel, Jeremy Darling +10
Astrometry, the measurement of positions and motions of the stars, is one of the oldest disciplines in Astronomy, extending back at least as far as Hipparchus' discovery of the pre…
