Topographic Measurement of Individual Laser Tracks in Alloy 625 Bare Plates

October 10, 2019
Author(s)
Richard E. Ricker, Jarred C. Heigel, Brandon M. Lane, Ivan Zhirnov, Lyle E. Levine
Additive manufacturing (AM) combines all of the complexities of materials processing and manufacturing into a single process. The digital revolution made this combination possible, but the commercial viability of these technologies for critical parts may

A Purely Algebraic Justification of the Kabsch-Umeyama Algorithm

October 9, 2019
Author(s)
James F. Lawrence, Javier Bernal, Christoph J. Witzgall
The constrained orthogonal Procrustes problem is the least-squares problem that calls for a rotation matrix that optimally aligns two matrices of the same order. Over past decades, the algorithm of choice for solving this problem has been the Kabsch

Observation of Strong Polarization Enhancement in Ferroelectric Tunnel Junctions

October 9, 2019
Author(s)
Linze Li, Xiaoxing Cheng, Thomas Blum, Huaixun Huyan, Yi Zhang, Colin A. Heikes, Xingxu Yan, Chaitanya Gadre, Toshihiro Aoki, Mingjie Xu, Lin Xie, Zijian Hong, Carolina Adamo, Darrell G. Schlom, Long-Qing Chen, Xiaoqing Pan
Ferroelectric heterostructures, with capability of storing data at ultrahigh densities, could act as the platform for next-generation memories. The development of new device paradigms has been hampered by the long-standing notion of inevitable

Are Reported Likelihood Ratios Well Calibrated?

October 8, 2019
Author(s)
Peter Vallone, Sarah Riman, Jan Hannig
In this work we introduce a new statistical methodology for empirically examining the validity of model-based Likelihood Ratio (LR) systems by applying a general statistical inference approach called generalized fiducial inference [1]. LR systems are

Generation and Detection of Spin-Orbit Coupled Neutron Beams

October 8, 2019
Author(s)
Dusan Sarenac, Connor Kapahi, Wangchun Chen, Charles W. Clark, David G. Cory, Michael G. Huber, Ivar Taminiau, Kirill Zhernenkov, Dmitry A. Pushin
Spin-orbit coupling of light has come to the fore in nano-optics and plasmonics, and is a key ingredient of topological photonics and chiral quantum optics. We demonstrate a basic tool for incorporating analogous effects into neutron optics: the generation

A Simulation Platform to Study the Human Body Communication Channel

October 7, 2019
Author(s)
Kamran Sayrafian, Katjana Krhac, Gregory Noetscher, Dina Simunic
Human Body Communication (HBC) is an attractive low complexity technology with promising applications in wearable biomedical sensors. In this paper, a simple parametric model based on the finite-element method (FEM) using a full human body model is

Optimized heat transfer at exceptional points in quantum circuits

October 7, 2019
Author(s)
Matti Partanen, Jan Goetz, K-Y Tan, Kassius Kohvakka, Vasilii Sevriuk, Russell Lake, Roope J. Kokkoniemi, Joni Ikonen, Dibyendu Hazra, Akseli Makinen, Eric Hyyppa, Leif Gronberg, Visa Vesterinen, Matti Silveri, Mikko Mottonen
Superconducting quantum circuits are potential candidates to realize a large-scale quantum computer. The envisioned large density of integrated components, however, requires a proper thermal management and control of dissipation. To this end, it is

Appraising the extensibility of optics-based metrology for emerging materials

October 4, 2019
Author(s)
Bryan M. Barnes, Mark-Alexander Henn, Martin Y. Sohn, Hui Zhou, Richard M. Silver
To advance computational capabilities beyond conventional scaling limitations, novel device architectures enabled by emerging materials may be required. Optics-based methodologies, central to modern-day process control, will be pursued by the

Formal Methods for Statistical Software

October 4, 2019
Author(s)
Paul E. Black
"Statistical software" encompasses several distinct classes of software. This report explains what formal methods, tools, and approaches may be able to increase assurance of results of using statistical software and implementing differential privacy. To

Network Charter: Manufacturing USA Program (Rev October 2019)

October 4, 2019
Author(s)
Michael F. Molnar
Under the authority of the Revitalize American Manufacturing and Innovation Act (RAMI) of 2014, the Secretary of Commerce established the Network for Manufacturing Innovation, generally called the Manufacturing USA network. The network, along with its
