BACnet Device Emulator Users' Guide

October 7, 2026
Author(s)
Michael Galler, Amanda Pertzborn, Parastoo Delgoshaei
The BACnet Device Emulator (BDE) is a tool built to help accelerate the development of Digital Twins in the built environment. By creating emulated BACnet subnets and controllers it enables testing and development to occur in a realistic manner.

Improved Correlations for the Static Dielectric Constant of Hydrogen

October 7, 2026
Author(s)
Guinevere Sellner, Liam Tenardi, Paul Stanwix, Eric May, Allan Harvey
Accurate values of the static dielectric constant of hydrogen are important for both fundamental thermophysical property calculations and emerging dielectric-based sensing applications in hydrogen liquefaction, storage, and processing systems. Previous

Value Assignment of Reference Material 8404 Almond Flour for Allergen Detection

October 7, 2026
Author(s)
Melissa Phillips, David Bunk, Ashley Green, James Yen
The National Institute of Standards and Technology (NIST) recently released RM 8404 Almond Flour for Allergen Detection, which is intended for harmonizing measurements of allergenic proteins in foods. The material was purchased from a commercial vendor and

October 7, 2026
Author(s)
Melissa Phillips, David Bunk, Ashley Green, James Yen
The National Institute of Standards and Technology (NIST) recently released RM 8405 Hazelnut Flour for Allergen Detection, which is intended for harmonizing measurements of allergenic proteins in foods. The material was purchased from a commercial vendor

Exponentially correlated Hylleraas-Configuration Interaction studies of atomic systems. IV. The Five Lowest singlet S and Five Lowest singlet P States of He and Oscillator Strengths, including Upper and Lower Bounds, for their Allowed Transitions

October 6, 2026
Author(s)
James Sims, Maria Ruiz, Bholanath Padhy
The Exponentially Correlated Hylleraas-Configuration Interaction method (E-Hy-CI) is a generalization of the Hylleraas-Configuration Interaction method (Hy-CI) in which the single r_ij} of an Hy-CI wave function is generalized to include both linear and

Tunable protein expression strength with toehold exchange riboregulators

October 4, 2026
Author(s)
Samuel Schaffter, Fernanda Piorino Macruz de Oliveira, Eugenia Romantseva
Toehold exchange (THE) riboregulators are a class of RNA molecules that use toehold-mediated strand exchange (TMSE) to regulate protein translation. The mechanism of TMSE offers many design parameters for precisely tuning the strength of protein expression

Residual AM and PM Noise of Selected X-Band Amplifiers

October 2, 2026
Author(s)
Archita Hati, Craig Nelson, Scott Littrell
In microwave systems design, amplitude modulation (AM) noise is often ignored relative to phase modulation (PM) noise. However, in high-performance applications requiring ultra-low PM noise, AM noise becomes a critical limiting factor due to AM-to-PM

Automation of the NIST Cryptographic Module Validation Program: April 2025 Status Report

September 30, 2026
Author(s)
Christopher Celi, Alexander Calis, William Barker, Ayayidjin Gabiam, Karen Kent, Shawn Geddis, Barry Fussell, Andrew Karcher, Douglas Boldt, Stephan Mueller, Yi Mao, Kyle Vitale
The Cryptographic Module Validation Program (CMVP) validates third-party assertions that cryptographic module implementations satisfy the requirements of Federal Information Processing Standards (FIPS) Publication 140-3, Security Requirements for

Building an In-Space Circular Economy - Seminar Series Report

September 29, 2026
Author(s)
Andrew Iams, Kelsea Schumacher, Jon Beam, Carolyn Pace, Dianne Poster
Traditional space activities have followed a linear, single-mission model in which spacecraft are designed, launched, operated, and ultimately disposed of through atmospheric reentry or relocation to graveyard orbits. As the commercial space sector grows

Applying Retail Markets and Transactive Resources for Grid Flexibility

September 28, 2026
Author(s)
David Holmberg, William Cox, Toby Considine
The electric grid faces strain driven by rapidly growing loads (for example, data centers, onshoring, and electrification), retiring dispatchable generation, and increasing intermittent renewables. Traditional utility mechanisms for managing customer

Standardizing a human TBMNK cell assay across instrument platforms: a new framework for producing high-quality, AI-ready reference dataset

September 28, 2026
Author(s)
Yu-Fen (Andrea) Wang, Huan-Yu Chen, Bor-Sheng Ko, Ningchun Xu, Nathan Dwarshuis, James Woods, Paul DeRose, Santosh Putta, Yu Max Qian, John Quinn, John Elliott, Virginia Litwin, Robert Hoffman, Sheng Lin-Gibson, Lili Wang
Introduction: Recent advances in regenerative medicine advanced therapies (RMAT) are revolutionizing health care by providing curative treatments for previously untreatable diseases. Flow cytometry assays have been used to measure critical quality

NISTCHO Cell Culture and Fed-Batch Bioreactor Protocols

September 24, 2026
Author(s)
Ioannis Karageorgos, William O'Dell, Vamsi Bolla, Hussain Dahodwala, Hussain Dahodwala, Zvi Kelman, John Marino
The NISTCHO cell system (RM 8675) provides a standardized Chinese hamster ovary (CHO) cell culture platform for studies of recombinant monoclonal antibody production and bioprocess characterization. Reproducible recovery, expansion, cultivation, and

On concrete spalling - BLEVE or no BLEVE

September 24, 2026
Author(s)
Jiann Yang
The BLEVE (boiling liquid expanding vapor explosion) hypothesis on fire-induced spalling of concrete was examined using the superheated liquid theory. Water within a heated concrete pore was used as an idealized system to examine the thermodynamic behavior
