Position-dependent neutron detection efficiency loss in 3He gas proportional counters

August 22, 2020
Author(s)
Patrick N. Peplowski, Zachary W. Yokley, Madison Liebel, Shuo Cheng, Richard C. Elphic, Shannon Hoogerheide, David J. Lawrence, Jeffrey Nico
The position-dependent neutron detection response of a 3He gas proportional counter (GPC) was characterized using a collimated (3-mm-wide), monoenergetic 0.05 eV neutron beam. For neutrons incident on the GPC near the ends of the active region, the neutron

The Design of an Instrument to Realize Small Torque at NIST

August 22, 2020
Author(s)
Leon S. Chao, Rafael Marangoni, Frank C. Seifert, Darine El Haddad, Jon R. Pratt, David B. Newell, Stephan Schlamminger
After the recent redefinition of the International System of Units (SI), torque no longer needs to be traceable to a calibrated mass in a gravitational field suspended from a known lever arm and disseminated through a chain of torque transducers.An SI

Nesting and Scheduling Problems for Additive Manufacturing: A Taxonomy and Review

August 21, 2020
Author(s)
Yosep Oh, Paul Witherell, Yan Lu, Timothy A. Sprock
With the trends of Industry 4.0 spanning physical and virtual worlds, Additive Manufacturing (AM) has been the mainstream for realizing complex geometries designed in computers. Meanwhile, a considerable number of AM studies have focused on effectively

Synthesis and Characterization of Bulk Nd 1-x Sr x NiO 2 and Nd 1-x Sr x NiO 3

August 21, 2020
Author(s)
Bi-Xia Wang, Hong Zheng, E. Krivyakina, Omar Chmaissem, Pietro Papa Lopes, Jeffrey W. Lynn, Leighanne C. Gallington, Y. Ren, S. Rosenkranz, J. F. Mitchell, D. Phelan
The recent reports of superconductivity in Nd 1-xSr xNiO 2/SrTiO 3 heterostructures have reinvigorated interest in potential superconductivity of low-valence nickelates. Synthesis of Ni 1+ -containing compounds is notoriously difficult. In the current work

Measuring Microfluidic Flow Rates: Monotonicity, Convexity and Uncertainty

August 20, 2020
Author(s)
Paul Patrone, Qing Hai Li, Gregory A. Cooksey, Anthony J. Kearsley
A class of non-linear integro-differential equations characterizing microfluidic measurements is considered. Under reasonable conditions, these non-linear integro-differential equations admit solutions that are convex functions of an interesting flow-rate

Structural and Dynamical Properties of Potassium Dodecahydro-Monocarba-Closo-Dodecaborate: KCB 11 H 12

August 20, 2020
Author(s)
Mirjana Dimitrievska, Hui Wu, Vitalie Stavila, Olga A. Babanova, Roman V. Skoryunov, Alexei V. Soloninin, Wei Zhou, Benjamin Trump
MCB 11H 12 (M: Li, Na) dodecahydro-monocarba-closo-dodecaborate salt compounds are known to have stellar superionic Li + and Na + conductivities in their high-temperature disordered phases, making them potentially appealing electrolytes in all-solid-state

Four Principles of Explainable Artificial Intelligence (Draft)

August 18, 2020
Author(s)
P Phillips, Carina Hahn, Peter Fontana, David A. Broniatowski, Mark A. Przybocki
We introduce four principles for explainable artificial intelligence (AI) that comprise the fundamental properties for explainable AI systems. They were developed to encompass the multidisciplinary nature of explainable AI, including the fields of computer

ARES: Automated Risk Estimation in Smart Sensor Environments

August 17, 2020
Author(s)
Athanasios Dimitriadis, Jose L. Flores, Boonserm Kulvatunyou, Nenad Ivezic, Ioannis Mavridis
Industry 4.0 adoption demands integrability, interoperability, composability, and security. Currently, integrability, interoperability and composability are addressed by next-generation approaches for enterprise systems integration such as model-based

Role of Uncertainty in the Durability of Composite Material Systems

August 17, 2020
Author(s)
Jeffrey T. Fong, Nathanael A. Heckert, James J. Filliben
This paper is a chapter invited by the editor of a book to be published by Elsevier in 2020. The title of the book is "Durability of Composite Systems," and the editor is Prof. Kenneth Reifsnider, N.A.E., University of Texas at Arlington, Arlington, TX, U

Temperature-induced heteroaggregation in polydisperse portlandite suspensions

August 17, 2020
Author(s)
Edward Garboczi, Gaurav Sant, Iman Mehdipour, Narayanan Neithalath, Mathieu Bauchy, Samanvaya Srivastava, Sharu Bhagavathi Kandy
Temperature is well-known to affect the aggregation behavior of colloidal suspensions. This paper elucidates the temperature dependence of the rheology of portlandite (calcium hydroxide: Ca(OH)2) suspensions that feature a high ionic strength and a pH
