Maximally efficient exchange in thin flow cells using density gradients

October 25, 2024
Author(s)
Megan Mitchell, Charles Majkrzak, David Hoogerheide
Flow cells are ubiquitous in laboratories and automated instrumentation and are crucial for ease of sample preparation, analyte addition, and buffer exchange. Often, the assumption that the fluids have exchanged completely in a flow cell is crucial to data

On the Design of a Firebrand Generator

October 25, 2024
Author(s)
Jiann Yang
Detailed design principles and calculations based on a generic firebrand generator with configuration commensurate with the NIST Firebrand Generators are provided. The generator is treated as a fluidized-bed reactor operating at the vertical dilute-phase

Progress towards accuracy evaluation of NIST-F4 Cesium fountain clock

October 24, 2024
Author(s)
Vladislav Gerginov, Gregory Hoth, Thomas Heavner, Jeffrey Sherman
This work presents preliminary results towards the evaluation of the NIST-F4 Cesium Primary Frequency Standard. We present measurements of NIST-F4 frequency instability and evaluation of some of its systematic frequency shifts and shift uncertainties.

Status Report on the First Round of the Additional Digital Signature Schemes for the NIST Post-Quantum Cryptography Standardization Process

October 24, 2024
Author(s)
Gorjan Alagic, Maxime Bros, Pierre Ciadoux, David Cooper, Quynh Dang, Thinh Dang, John M. Kelsey, Jacob Lichtinger, Carl A. Miller, Dustin Moody, Rene Peralta, Ray Perlner, Angela Robinson, Hamilton Silberg, Daniel Smith-Tone, Noah Waller, Yi-Kai Liu
The National Institute of Standards and Technology is in the process of evaluating public-key digital signature algorithms through a public competition-like process for potential standardization. Any signature scheme eventually selected would augment

The Global and Local Structure of Medium-Scale Pool Fires

October 24, 2024
Author(s)
Kunhyuk Sung, Ryan Falkenstein-Smith, Matthew Bundy, Marco Fernandez, Anthony Hamins
A series of experiments are reported that characterize key features of the structure of eight medium-scale pool fires (0.3 m to 0. 4 m) burning a variety of liquid and gaseous fuel types, including 30 cm diameter liquid pool fires burning methanol, ethanol

An Evaluation of Methods for Assessing Robot Kinematic Model Accuracy in the Presence of Noise

October 23, 2024
Author(s)
Mitchell R. Woodside, Patrick Bazzoli, Philip A. Olubodun, J. Adam Nisbett, Helen Qiao, Douglas A. Bristow
While there are many works developing methods for modeling and calibrating robot kinematics, assessing the accuracy of those models has received little attention. However, accuracy assessment is critically important for applications where the robot must

Blueprint for Deploying 5G O-RAN Testbeds: A Guide to Using Diverse O-RAN Software Stacks

October 23, 2024
Author(s)
Peng Liu, Kyehwan Lee, Fernando Cintron, Simeon Wuthier, Bhadresh Savaliya, Douglas Montgomery, Richard Rouil
This documentation serves as a blueprint for new researchers, offering a comprehensive guide on establishing an Open Radio Access Network (O-RAN) testbed from scratch. It details the O-RAN architecture and the supporting software stacks required for each

Microstructure and mechanical properties of laser powder bed fusion Ti-6Al-4V after HIP treatments with varied temperatures and cooling rates

October 22, 2024
Author(s)
Nicholas Derimow, Jake Benzing, Howard Joress, Austin McDannald, Ping Lu, Frank DelRio, Newell Moser, Matthew Connolly, Alec Saville, Orion Kafka, Chad Beamer, Ryan Fishel, Chris Hadley, Nikolas Hrabe
This work investigated non-standard HIP cycles for PBF-L Ti-6Al-4V and characterized microstructure and tensile properties to compare between material that originated from the same build. For 920 °C, faster cooling rates (100 °C/min, 2000 °C/min) were

Measuring Post-Disaster Accessibility to Essential Goods and Services: Proximity, Availability, Adequacy, and Acceptability Dimensions

October 21, 2024
Author(s)
Amin Enderami, Elaina Sutley, Jennifer Helgeson, Leonardo Duenas-Osorio, Maria Watson, John van de Lindt
Rapid restoration of access to essential goods and services has long been regarded as paramount for community recovery. Yet, there remains ambiguity in how access should be defined, measured, or operationalized. Defining accessibility as the ability to use

NIST Cybersecurity Framework 2.0: Enterprise Risk Management Quick-Start Guide

October 21, 2024
Author(s)
Stephen Quinn, Victoria Pillitteri, Matthew Barrett, Matthew Smith, Gregory Witte
This guide provides an introduction to using the NIST Cybersecurity Framework (CSF) 2.0 for planning and integrating an enterprise-wide process for integrating cybersecurity risk management information, as a subset of information and communications

NIST Cybersecurity Framework 2.0: Quick-Start Guide for Using the CSF Tiers

October 21, 2024
Author(s)
Stephen Quinn, Cherilyn Pascoe, Matthew Barrett, Karen Scarfone, Gregory Witte
This Quick-Start Guide describes how to apply the CSF 2.0 Tiers. CSF Tiers can be applied to CSF Organizational Profiles to characterize the rigor of an organization's cybersecurity risk governance and management outcomes. This can help provide context on

Deformation of PMMA samples in cone calorimeter and anaerobic gasification experiments

October 20, 2024
Author(s)
Karen De Lannoye, Isaac Leventon, Lucie Hasalova, Alexander Belt, Ernst-Arndt Reinecke, Lukas Arnold
16 Cone calorimetry and anaerobic gasification experiments are often used to assess material 17 flammability of bench-scale (coupon sized) samples in response to well-characterized external radiant 18 heating. In this project, it has been observed that the
