Author(s)
Polette Centellas, Kyle Mehringer, Andrew Bowman, Katherine Evans, Parth Vagholkar, Travis Thornell, Liping Huang, Sarah Morgan, Christopher Soles, Yoan Simon, Edwin Chan
Understanding the physical and chemical response of materials to impulsive deformation is crucial for applications ranging from soft robotic locomotion to space exploration to seismology. However, investigating material properties at extreme strain rates

On a conjecture that strengthens Kundu's k-factor Theorem

October 6, 2024
Author(s)
James Shook
Let π = (d1, . . . , dn) be a non-increasing degree sequence with even n. In 1974, Kundu showed that if Dk(π) = (d1 − k, . . . , dn − k) is graphic, then some realization of π has a k-factor. For r ≤ 2, Busch et al. and later Seacrest for r ≤ 4 showed that

October 3, 2024
Author(s)
Zev Kronenberg, Nathanael Olson, Justin Zook, Michael Eberle
Recent advances in genome sequencing have improved variant calling in complex regions of the human genome. However, it is difficult to quantify variant calling performance because existing standards often focus on specificity, neglecting completeness in

Cryogenic Sapphire Optical Reference Cavity with 1 x 10^-16 fractional instability

October 2, 2024
Author(s)
Jose Valencia, George Iskandr, Nicholas Nardelli, David Leibrandt, David Hume
The frequency stability of a laser locked to an optical reference cavity is fundamentally limited by thermal noise in the cavity length, caused by local thermal fluctuations of the strain and index of refraction of the cavity components. These fluctuations

Jointly benchmarking small and structural variant calls with vcfdist

Author(s)
Tim Dunn, Justin Zook, James Holt, Satish Narayanasamy
In this work, we extend vcfdist to be the first variant call benchmarking tool to jointly evaluate phased single-nucleotide polymorphisms (SNPs), small insertions/deletions (INDELs), and structural variants (SVs) for the whole genome. First, we find that a
