Measuring downstream supply chain losses due to power disturbances

September 16, 2022
Douglas Thomas, Juan Fung
Power outages in the U.S. affect many firms' economic activity and are likely to result in downstream supply chain disruptions. This paper examines the impact of power disturbances in the supply chain for four industries: manufacturing, durable goods

Structure Separation Experiments: Shed Burns without Wind

September 15, 2022
Alexander Maranghides, Shonali Nazare, Eric Link, Matthew Bundy, Matthew Hoehler, Steven Hawks, Frank Bigelow, William (Ruddy) Mell, Anthony Bova, Derek McNamara, Tom Milac, Faraz Hedayati, Daniel Gorham, Xareni Monroy, Murray Morrison, Bob Raymer, Frank Frievalt, William Walton
This report describes the experiments conducted during the first phase of a multi-phase project designed to assess structure-to-structure fire spread for structures in the Wildland-Urban Interface (WUI). The experiments focused on quantifying thermal

Staging Cybersecurity Risks for Enterprise Risk Management and Governance Oversight

September 14, 2022
Stephen Quinn, Nahla Ivy, Greg Witte, Matthew Barrett, R.K. Gardner
This document is the third in a series that supplements NIST Interagency/Internal Report (NISTIR) 8286, Integrating Cybersecurity and Enterprise Risk Management (ERM). This series provides additional details regarding the enterprise application of

Structural and electronic properties of Cu3InSe4

September 11, 2022
Oluwagbemiga Ojo, Winnie Wong-Ng, Teiyan Chang, Yu-Sheng Chen, George S. Nolas
Single crystals of the previously unascertained ternary chalcogenide Cu3InSe4 were obtained by induction melting, allowing for a complete investigation of the crystal structure by employing high-resolution single-crystal synchrotron X-ray diffraction

Digital Evidence Preservation: Considerations for Evidence Handlers

September 8, 2022
Barbara Guttman, Douglas R. White, Shannan Williams, Tracy Walraven
The preservation of digital evidence (DE) presents unique problems beyond traditional evidence preservation. This document addresses considerations related to the preservation of digital evidence. This document is part of a series on evidence management

Energy Broadening of Neutron Depth Profiles by Thin Polyamide Films

September 7, 2022
Jamie Weaver, Robert Gregory Downing, Anna Job, Kedar Manandhar, Ichiro Takeuchi
A protective covering is often required for neutron depth profiling (NDP) measurements of sensitive materials (e.g., Li-ion batteries). Addition of this layer can increase NDP profile energy broadening and depth assignment uncertainty. This study evaluates

Improved Uranium Particle Analysis by SIMS using O3- Primary Ions

September 6, 2022
Evan Groopman, Todd Williamson, David S. Simons
We have investigated the use of negative molecular oxygen primary ion beams (i.e., O2- and O3-) to determine the benefits of using such beams for uranium particle SIMS analyses. Typically, O- is the most practical negative primary ion species for both age

N-DISE: NDN-Based Data Distribution for Large-Scale Data-Intensive Science

September 6, 2022
Edmund Yeh, Harvey Newman, Lixia Zhang, Jason Cong, Susmit Shannigrahi, Yuanhao Wu, Catalin Iordache, Volkan Mutlu, Sankalpa Timilsina, Sichen Song, Michael Lo, Ran Liu, Chengyu Fan, Raimondas Sirvinskas, Justas Balcas, Yuezhou Liu, Davide Pesavento, Junxiao Shi, Lotfi Benmohamed
To meet unprecedented challenges faced by the world's largest data- and network-intensive science programs, we design and implement a new, highly efficient and field-tested data distribution, caching, access and analysis system for the Large Hadron

Network analysis approach to Likert-style surveys

September 2, 2022
Robert Dalka, Diana Sachmpazidi, Charles Henderson, Justyna Zwolak
Likert-style surveys are a widely used research instrument to assess respondents' preferences, beliefs, or experiences. In this paper, we propose and demonstrate how network analysis (NA) can be employed to model and evaluate the interconnectedness of

Overcoming Technological Barriers in Microfluidics: Leakage Testing

September 1, 2022
Vania Silverio, Suvajyoti Guha, Armelle Keiser, Rucha Natu, Darwin Reyes-Hernandez, Henne van Heeren, Nicolas Verplanck, Luke Herbertson
The miniaturization of laboratory procedures for Lab-on-Chip (LoC) devices and translation to various platforms such as single cell analysis or Organ-on-Chip (OoC) systems are revolutionizing the life sciences and biomedical fields. As a result

NIST 2022 Language Recognition Evaluation Plan

August 31, 2022
Yooyoung Lee, Craig Greenberg, Lisa Mason, Elliot Singer
The 2022 NIST language recognition evaluation (LRE22) is the 9th cycle in an on-going language recognition evaluation series that began in 1996. The objectives of the evaluation series are (1) to advance technologies in language recognition with innovative

Design and Application of the Reconfigurable Mobile Manipulator Artifact (RMMA)

August 30, 2022
Roger V. Bostelman, Omar Aboul-Enein, Soocheol Yoon, Ya-Shian Li-Baboud
Robot arms onboard mobile bases, or mobile manipulators, are advancing and measurement of these systems is critical for robust safety and performance. As mobile manipulators flexibly fixture (i.e., do not fasten) to a worktable or object, they require
