Results of the 2023 Rapid DNA Multi-Laboratory Study - I-Chip

December 4, 2024
Author(s)
Erica Romsos, Lilliana Moreno, Douglas Hares
Identical sensitivity and mixture sample sets were provided to six external laboratories to evaluate the recent enhancements to the Rapid DNA technology for crime scene-type samples. Data were returned to the Federal Bureau of Investigation and the

Two tests of variance homogeneity for clustered data where group size is informative

December 3, 2024
Author(s)
Mary Gregg, Adam Creuziger, Somnath Datta, Douglas Lorenz
To evaluate variance homogeneity among groups for clustered data, Iachine et al. (Robust tests for the equality of variances for clustered data. J Stat Comput Simul 2010;80(4):365–377) introduced an extension of the well-known Levene test. However, this

Noiseless Loss Suppression for Entanglement Distribution

December 2, 2024
Author(s)
Cory Nunn, Daniel Jones, Todd Pittman, Brian Kirby
Recent work by Mičuda et al. [Phys. Rev. Lett 109, 180503 (2012)] suggests that pairing noiseless amplification with noiseless attenuation can conditionally suppress loss terms in the direct transmission of quantum states. Here we extend this work to

Optical Characterization of Parasitic Motion in a Long-Stroke Shaker

December 2, 2024
Author(s)
Jared Strait, Richard A. Allen
We present an optical scheme to simultaneously characterize the cross-axis and rotational parasitic motions of a long-stroke shaker. By leveraging the geometric properties of a corner cube retroreflector mounted on the shaker load table, we independently

Heterogeneously integrated AlGaAs/GaAs photodiodes on tantala waveguides

December 1, 2024
Author(s)
Masoud Jafari, Tasneem Fatema, David Carlson, Scott Papp, Andreas Beling
We demonstrate the first heterogeneously integrated high-speed waveguide photodiode (PD) on tantalum pentoxide (Ta2O5, or tantala) for visible light detection. The PDs have 100 pA dark current, more than 56% quantum efficiency (QE) between 635 nm and 780

VOC Emission Rates from an Indoor Surface Using a Flux Chamber and PTR-MS

December 1, 2024
Author(s)
Han Huynh, Jenna Ditto, Michael Link, Dustin Poppendieck, Delphine Farmer, Marina Vance, Jonathan Abbatt
Arising from the Chemical Assessment of Surfaces and Air (CASA) 2022 study at the NIST Net-Zero Energy Residential Test Facility (NZERTF), this paper presents the first evaluation of indoor surface emissions to a house measured with a surface flux chamber

TRC/NIST PUBLIC DATA DOMAIN

November 29, 2024
Author(s)
Vladimir Diky
A conference presentation describing the TRC/NIST public data domain.

Graphic Approximation of Integer Sequences

November 25, 2024
Author(s)
Brian D. Cloteaux
A variety of network modeling problems begin by generating a degree sequence drawn from a given probability distribution. If the randomly generated sequence is not graphic, we give two new approaches for generating a graphic approximation of the sequence

NIST Cybersecurity Framework 2.0: Resource & Overview Guide (French translation)

November 25, 2024
Author(s)
Kristina Rigopoulos, Stephen Quinn, Cherilyn Pascoe, Jeffrey Marron, Amy Mahn, Daniel Topper
The NIST Cybersecurity Framework (CSF) 2.0 can help organizations manage and reduce their cybersecurity risks as they start or improve their cybersecurity program. The CSF outlines specific outcomes that organizations can achieve to address risk. Other
