On the rank of a random binary matrix
C. Cooper, A. M. Frieze, W. Pegden
We study the rank of the random 0/1 matrix where each column is chosen independently from the set of 0/1 vectors with exactly 1's. Here…
Network science: a review focused on tourism
R. Baggio, N. Scott, C. Cooper
This paper presents a review of the methods of the science of networks with an application to the field of tourism studies. The basic definitions and computational techniques are d…
Understanding and Improving Data Repurposing
J. Parsons, R. Lukyanenko, B. Greenwood +1
We live in an age of unprecedented opportunities to use existing data for tasks not anticipated when those data were collected, resulting in widespread data repurposing. This comme…
Seeding the m = 0 instability in dense plasma focus Z-pinches with a hollow anode
J. X. Liu, J. Sears, M. McMahon +7
The dense plasma focus (DPF) is a classic Z-pinch plasma device that has been studied for decades as a radiation source. The formation of the m = 0 plasma instability during the co…
Fermilab experience of post-annealing losses in SRF niobium cavities due to furnace contamination and the ways to its mitigation: a pathway to processing simplification and quality factor improvement
A. Grassellino, A. Romanenko, A. Crawford +10
We investigate the effect of high temperature treatments followed by only high-pressure water rinse (HPR) of superconducting radio frequency (SRF) niobium cavities. The objective i…
Gamma-Ray Burst and Relativistic Shells: The Surface Filling Factor
E. E. Fenimore, C. Cooper, E. Ramirez-Ruiz +3
The variability observed in many complex gamma-ray bursts (GRBs) is inconsistent with causally connected variations in a single, symmetric, relativistic shell interacting with the…
Knowledge transfer in a tourism destination: the effects of a network structure
R. Baggio, C. Cooper
Tourism destinations have a necessity to innovate to remain competitive in an increasingly global environment. A pre-requisite for innovation is the understanding of how destinatio…
Investigations of surface quality and SRF cavity performance
G. Wu, M. Ge, P. Kneisel +4
Magnetic field enhancement has been studied in the past through replica and cavity cutting. Considerable progress of niobium cavity manufacturing and processing has been made since…
The Dark Energy Camera
B. Flaugher, H. T. Diehl, K. Honscheid +115
The Dark Energy Camera is a new imager with a 2.2-degree diameter field of view mounted at the prime focus of the Victor M. Blanco 4-meter telescope on Cerro Tololo near La Serena,…
