A precise value of the neutron lifetime is important in several areas of physics, including determinations of the quark-mixing matrix element |Vud|, related tests of the Standard Model, and predictions of light element abundances in Big Bang

Good reporting practice for thermophysical and thermochemical property measurements (IUPAC Technical Report)

April 16, 2021
Author(s)
Ala Bazyleva, Jens Abildskov, Andre Anderko, Olivier Baudouin, Yury Chernyak, Jean-Charles de Hemptinne, Vladimir Diky, Ralf Dohrn, J. R. Elliott, Johan Jacquemin, Jean-Noel Jaubert, Kevin Joback, Ursula Kattner, Georgios Kontogeorgis, Herbert Loria, Paul M. Mathias, John O'Connell, Wolffram Schroer, G. J. Smith, Ana Soto, Shu Wang, Ronald D. Weir
Scientific projects frequently involve measurements of thermophysical, thermochemical, and other related properties of chemical compounds and materials. These measured property data have significant potential value for the scientific community, but

Characterization and Absolute Calibration of an AERONET-OC Radiometer

April 15, 2021
Author(s)
B. Carol Johnson, Giuseppe Zibordi, Steven W. Brown, Michael Feinholz, Mikhail Sorokin, Ilya Slutsker, John T. Woodward IV, Howard Yoon
The Ocean Color component of the global Aerosol Robotic Network (AERONET-OC) utilizes CE-318 sun photometers modified for above-water radiometry from fixed structures such as oil rigs, lighthouses, and service platforms. Primarily, AERONET-OC measurements

Jeffrey S. Nico, Shannon M. Hoogerheide, Hans Pieter Mumm, Murad Sarsour, J Amadio, Eamon Anderson, Libertad Barron-Palos, Bret Crawford, Chris Crawford, D. Esposito, Walter Fox, I Francis, J Fry, Chris Haddock, Adam Holley, Kirill Korsak, J Lieers, S Magers, M. Maldonado-Velazquez, D Mayorov, T Okudaira, C Paudel, S Santra, H.M. Shimizu, William M. Snow, A. Sprow, K. Steen, H E. Swanson, John Vanderwerp, P. A. Yergeau
The neutron spin rotation (NSR) collaboration used parity-violating spin rotation of transversely polarized neutrons transmitted through a 0.5 m liquid helium target to constrain weak coupling constants between nucleons. While consistent with theoretical

Implementing a Registry Federation for Materials Science Data Discovery

April 13, 2021
Author(s)
Raymond L. Plante, Chandler Becker, Andrea M. Medina-Smith, Kevin G. Brady, Alden A. Dima, Benjamin J. Long, Laura M. Bartolo, Robert Hanisch
As a result of a number of national initiatives, we are seeing rapid growth in the data important to materials science that are available over the web. Consequently, it is becoming increasingly difficult for researchers to learn what data are available and

April 12, 2021
Author(s)
N. Alan Heckert, Laura Mundy, Paul E. Stutzman
A new Standard Reference Material® (SRM) for portland cement clinker has been produced for the Office of Standard Reference Materials at the National Institute of Standards and Technology (NIST). The SRM clinkers are intended for use in developing and

Challenge Design and Lessons Learned from the 2018 Differential Privacy Challenges

April 12, 2021
Author(s)
Diane Ridgeway, Mary Theofanos, Terese Manley, Christine Task
The push for open data has made a multitude of datasets available enabling researchers to analyze publicly available information using various statistical and machine learning methods in support of policy development. An area of increasing interest that is

Combinatorial Testing Metrics for Machine Learning

April 12, 2021
Author(s)
Erin Lanus, Laura Freeman, D. Richard Kuhn, Raghu N. Kacker
This short paper defines a combinatorial coverage metric for comparing machine learning (ML) data sets and proposes the differences between data sets as a function of combinatorial coverage. The paper illustrates its utility for evaluating and predicting

Laboratory Tests of a Prototype Carbon Dioxide Ground-Source Air Conditioner

April 12, 2021
Author(s)
Harrison Skye, Wei Wu
Environmental concerns are driving regulations to reduce the use of hydrofluorocarbons (HFCs) with high global warming potential (GWP) as refrigerants in heat pumps. CO2 is an attractive alternative refrigerant because is it 'environmentally friendly' in
