Femtometer-amplitude imaging of coherent super high frequency vibrations in micromechanical resonators

February 4, 2022
Author(s)
Lei Shao, Vikrant Gokhale, Bo Peng, Peng-Hui Song, Jingjie Cheng, Justin Kuo, Amit Lal, Wen-Ming Zhang, Jason Gorman
The ability to measure femtometer scale vibrations at microwave frequencies is important in applications as diverse as ultracoherent resonators for 5G wireless communications, ultrasensitive detectors for mass and force, and acoustic resonators for quantum

Graph Convolutional Neural Network Applied to the Prediction of Normal Boiling Point

February 4, 2022
Author(s)
Chen Qu, Anthony J. Kearsley, Barry I. Schneider, Walid Keyrouz, Thomas C. Allison
In this article, we describe training and validation of a machine learning model for the prediction of organic compound normal boiling points. Data are drawn from the experimental literature as captured in the NIST Thermodynamics Research Center (TRC)

Making Semantic Structures Explicit: Developing and Evaluating Tools and Techniques to Support Understanding of Large Cybersecurity Corpora

February 4, 2022
Author(s)
Ira Monarch, Jacob Collard, Sangjin Shin, Eswaran Subrahmanian, Talapady N. Bhat, Ram D. Sriram
This report describes the adaptation, composition and use of natural language processing, machine learning and other computational tools to help make implicit informational structures in very large technical corpora explicit. The tools applied to the

Recommended Criteria for Cybersecurity Labeling of Consumer Software

February 4, 2022
Author(s)
Michael Ogata, Amy Phelps, Julie Haney
Executive Order (EO) 14028, "Improving the Nation's Cybersecurity," tasks the National Institute of Standards and Technology (NIST), in coordination with the Federal Trade Commission (FTC) and other agencies, to initiate pilot programs for cybersecurity

Thickness-dependent transport properties and photoresponse in MoSe2 field-effect transistors

February 4, 2022
Author(s)
Shiqi Guo, Sergiy Krylyuk, Hsin Y. Lee, Ratan K. Debnath, Albert Davydov, Mona E. Zaghloul
Transition metal dichalcogenides have been studied extensively due to their unique properties in low-dimensional limits. In this work, we have examined the effect of MoSe2 layer thickness on its electrical properties in a field effect transistor (FET)

Operator scaling dimensions and multifractality at measurement-induced transitions

February 3, 2022
Author(s)
Michael Gullans, Zabalo Aidan, Justin Wilson, Romain Vasseur, Andreas Ludwig, Sarang Gopalakrishnan Gopalakrishnan, David Huse, Jed Pixley
Repeated local measurements of quantum many body systems can induce a phase transition in their entanglement structure. These measurement-induced phase transitions (MIPTs) have been studied for various types of dynamics, yet most cases yield quantitatively

A Wearable Wireless Monitoring System for the Detection of Pulmonary Edema

February 2, 2022
Author(s)
Kamran Sayrafian, Katjana Krhac, Uzay Bengi, Sema Dumanli Oktar
In this paper we investigate the feasibility of a simple wearable system that can be used at home to detect or monitor excess fluid buildup in the lungs. This is a medical condition referred to as pulmonary edema. A methodology has been developed to

Characterizing Frequency Stability Measurements having Multiple Data Gaps

February 2, 2022
Author(s)
David A. Howe, Noah Schlossberger
Time series measurements with data gaps (dead times) prevent accurate computations of frequency variances such as the Allan variance (AVAR) and its square-root ADEV. To extract frequency distributions, data must be sequentially ordered and equally spaced

Detection of individual spin species via frequency-modulated charge pumping

February 2, 2022
Author(s)
James Ashton, Mark Anders, Jason Ryan
We utilize the recently developed frequency-modulated charge pumping technique to detect a single charge per cycle, which strongly suggests a single Si/SiO2 interface trap. This demonstration in sub-micron MOSFETs, in which scaling of the gate oxide yields

Dynamically Preferred State with Strong Electronic Fluctuations from Electrochemical Synthesis of Sodium Manganate

February 2, 2022
Author(s)
Xi Chen, Yichao Wang, Yiping Wang, Rebecca Dally, Kamila Wiaderek, Tianyu Qiao, Jue Liu, Enyuan Hu, Kenneth Burch, Jeffrey W. Lynn, Xin Li
Electrochemical (de-)intercalation is a delicate method to precisely control the alkaline ion composition in alkaline transition metal oxides. Due to the interactions among alkaline ions, and with metal oxide layers, alkaline and transition metal charge

EVAP-COND Simulation Tool with Optimization Refrigerant Circuitry

February 1, 2022
Author(s)
Piotr Domanski
EVAP-COND is a software package that contains simulation models for a finned-tube evaporator and condenser. The modeling scheme allows for specifying complex refrigerant circuits, modeling refrigerant distribution between these circuits, and accounting for

Laser Spot Welding of Additive Manufactured 304L Stainless Steel

February 1, 2022
Author(s)
Brian Simonds, Cheryl Hawk, Stephen Liu, Daniel Javernick, Robin Pacheco, Michael Brand, Jack Tanner, Greg Vigil
The goal of this work is to understand if an additively manufactured 304L stainless steel exhibited similar spot welding behavior as wrought 304L stainless steel. Due to the many differences between an additively manufactured component and wrought product

Low-Background Neutron Reflectometry from Solid/Liquid Interfaces

February 1, 2022
Author(s)
David Hoogerheide, Joseph Dura, Brian B. Maranville, Charles F. Majkrzak
Liquid cells are an increasingly common sample environment for neutron reflectometry experiments and are critical for measuring the properties of materials at solid/liquid interfaces. Background scattering determines the maximum useful scattering vector
