On-Chip Parametric Synchronization of a Cavity Soliton Microcomb

May 13, 2025
Author(s)
Gregory Moille, Pradyoth Shandilya, Miro Erkintalo, Curtis Menyuk, Kartik Srinivasan
Synchronization of oscillators is ubiquitous in nature. Often, the synchronized oscillators couple directly, yet in some cases synchronization can arise from their parametric interactions. Here, we theoretically predict and experimentally demonstrate the

Selecting longitudinal community outcomes for resilience indicator validation

May 13, 2025
Author(s)
Donghwan Gu, Maria Dillard, Michael Gerst, Jarrod Loerzel
Assessing community resilience is a long-sought goal in multiple fields of study and practice. Community resilience frameworks have been designed to estimate the level of resilience through varying sets of cross-sectional indicators. However, community

Supporting Production Consistency for Cement

May 12, 2025
Author(s)
Aron Newman, Cody Strack
Concrete is the second most used substance in the world after water. Concrete manufacturers produce 14 billion cubic meters annually, with a market size of $440 billion. The concrete industry is developing new technologies to decrease its carbon footprint

A Fully Registered In-Situ and Ex-Situ Dataset for Metal Powder Bed Fusion Additive Manufacturing: Data Processing, Feature Extraction, Registration, and Uncertainties

May 8, 2025
Author(s)
Zhuo Yang, Yan Lu, Ho Yeung, Brandon Lane, Nicole Van Handel
This document details the data registration process for the previously published datasets from Additive Manufacturing Metrology Testbed (AMMT) parts, "Overhang Part X4," generated at the National Institute of Standards and Technology. The two datasets —one

Top-Down Scoring of Spectral Fitness by Image Analysis for Protein Structure Validation

May 6, 2025
Author(s)
Benjamin Harding, Barry DeZonia, Rajat Garg, Ziling Hu, Frank Delaglio, Tim Grant, Chad Rienstra
Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for protein structure determination, but traditional approaches require extensive manual assignment of hundreds to thousands of resonances. Here we present NMRFAM-BPHON, a novel "top

Broadband Optoelectronic Mixer for Terahertz Frequency-Comb Measurements

May 5, 2025
Author(s)
Jizhao Zang, Jesse Morgan, Andreas Beling, Scott Papp
We demonstrate ultra-broadband optoelectronic mixing of frequency combs that provides phase-coherent detection of a repetition frequency up to 500 GHz, using a high-speed modified uni-traveling carrier (MUTC) photodiode. Nonlinear photo-electron effects in

China's Manufacturing Innovation Centers: A Benchmarking Report for the Manufacturing USA Network

May 5, 2025
Author(s)
Michael Molnar, Kelley Rogers, Frank Gayle, Susan Ipri-Brown, Mai Tran, Joseph Long, Clifton Ray, Albert Shih, Douglas Thomas
This review of China's Manufacturing Innovation Centers (MICs) describes the status of the country's flagship manufacturing innovation program. At least 33 MICs have been established to date, suggesting that China is within reach of its goal of 40 MICs by

NIST GenAI (Pilot): an Overview of Text-to-Text Evaluation Results

May 5, 2025
Author(s)
Yooyoung Lee, Hariharan Iyer
The 2024 NIST Generative AI (GenAI) Pilot Study focuses on evaluating text-to-text (T2T) generation and discrimination tasks to assess the capabilities and limitations of generative AI models. The study aims to measure the effectiveness of AI-generated

Certification of Standard Reference Material(R) 1989 Monodisperse Irregularly Shaped Epoxy-Based Particles (Nominal 100 mm, 150 mm, 220 mm)

May 2, 2025
Author(s)
Srivalli Telikepalli, Dean Ripple, Michael Carrier, Kristen Steffens, David Newton, Christopher Montgomery, Nicholas Ritchie, Anthony Asmar, Michael Halter
Standard Reference Material (SRM) 1989 is a NIST particle standard produced using photolithographic methods and delivers a certified value for particle size of an irregularly shaped particle. This SRM was developed to allow a more accurate monitoring of

On the chemomechanics of bubble growth in hydrogen attack of plain carbon steels

May 2, 2025
Author(s)
May Martin, Kshitij Vijayvargia, T Nguyen, Mohsen Dadfarnia, Aleksandar Staykov, Petros Sofronis, Masanobu Kubota, John Pugh
High temperature hydrogen attack (HTHA) is a form of degradation of carbon steels exposed to high temperature and high-pressure hydrogen whereby internal hydrogen reacting with carbides forms methane gas bubbles with an associated loss in strength and

A re-assessment of archived (1989-2006) beluga liver from the North American Arctic with non-targeted analysis reveals brominated chemicals of emerging concern

May 1, 2025
Author(s)
Jacqueline Bangma, Chris Fuller, James McCord, Heather Whitehead, Richard Liberatore, Jason Boettger, Amanda Moors, Rebecca Pugh, Steven O'Connell, Jessica Reiner
In 2011, 68 archived beluga whale (Delphinapterus leucas) liver samples collected from Cook Inlet and the eastern Chukchi Sea from 1989 to 2006 were characterized for 12 per- and polyfluoroalkyl substances (PFAS) using targeted mass spectroscopy (MS)

Altermagnetic band splitting in 10 nm epitaxial CrSb thin films

Altermagnets are a newly identified family of collinear antiferromagnets with a momentum-dependent spin-split band structure of non-relativistic origin, derived from spin-group symmetry-protected crystal structures. Among candidate altermagnets, CrSb is

MEMSDuino: An Arduino-Based MEMS Switch Controller

May 1, 2025
Author(s)
Lafe Spietz, Adam Sirois, Nathan Flowers-Jacobs, Peter Hopkins, Samuel Benz, Steve Waltman
Radio frequency cryogenic switches are a critical enabling technology for quantum information science, both for calibration and high throughput testing of samples. Traditionally solenoid-based switches have been used, but transition is being made to MEMS

The Burning Characteristics of 3 m to 6 m Dry Douglas-Fir Trees
