Nenad Ivezic, Boonserm Kulvatunyou, Elena Jelisic, Marija Jankovic, Zoran Marjanovic
The number of Industry 4.0, Internet of Things, and cloud service implemen-tations are growing rapidly. In the resulting, emerging, cross-industry, coop-erative environments, a common understanding of message standards will be necessary to enable better

Compositional models for power systems

September 8, 2019
Author(s)
Dhananjay Anand, Blake S. Pollard, Spencer J. Breiner, John S. Nolan, Eswaran Subrahmanian
The problem of integrating multiple overlapping models and data is pervasive in engineering, though often implicit. We consider this issue of model management in the context of the electrical power grid, as it transitions from centralized generation with

Optical Quantum Memory Applications in Quantum Communication

Author(s)
Oliver T. Slattery, Xiao Tang, Lijun Ma
Optical quantum memory is a device that can store the quantum state of photons and retrieve it with high fidelity on demand. Many approaches to quantum memory have been proposed and demonstrated. Quantum memory can be used to enhance performance in many

Comparison of Anion and Cation Dynamics in a Carbon-Substituted closo-Hydroborate Salt: 1 H and 23 Na NMR Studies of Solid-Solution Na 2 (CB 9 H 10 )(CB 11 H 12 )

Author(s)
A. V. Soloninin, R. V. Skoryunov, O. A. Babanova, A. V. Skripov, Mirjana NMN Dimitrievska, Terrence J. Udovic
The hexagonal mixed-anion solid solution Na 2(CB 9H 10)(CB 11H 12) shows the highest room-temperature ionic conductivity among all known Na-ion conductors. To study the dynamical properties of this compound, we have measured ghe 1H and 23Na nuclear

Data-driven approaches to optical patterned defect detection

September 5, 2019
Author(s)
Mark-Alexander Henn, Hui Zhou, Bryan M. Barnes
Computer vision and classification methods have become increasingly popular in recent years due to ever-increasing computation power. While advances in semiconductor devices are the basis for this growth, few publications have probed the benefits of data

110th Anniversary: Properties of Imidazolium-based Ionic Liquids Bearing both Benzylic and n-Alkyl Substituents

September 4, 2019
Author(s)
Joe W. Magee, Shuai Qian, Kathryn E. O'Harra, Grayson P. Dennis, Richard D. Noble, Jason E. Bara, Alexia Finotello
Reports of imidazolium-based ionic liquids (ILs) with at least one benzylic substituent bound to the imidazolium cation is far less common than the ubiquitous 1-alkyl-3-methylimidazolium ILs ([Cnmim][X]). Yet, there is significant motivation to determining

Accessing New Charge-Transfer Complexes by Mechanochemistry: A Tetrathiafulvalene Chloranilic Acid Polymorph Containing Segregated Tetrathiafulvalene Stacks

September 4, 2019
Author(s)
Jeffrey Jones, Vinh Ta Phuoc, Leire del Campo, Nestor E. Massa, Craig Brown, Silvina Pagola
Two polymorphs of tetrathiafulvalene chloranilic acid (ITF-CAH 2) have been synthesized by mechanochemistry. The previously known "ionic" polymorph (form I), was prepared by liquid assisted grinding (LAG) using various highly polar solvents; as well as

L. Herrera Diez, Y. T. Liu, Dustin A. Gilbert, M. Belmeguenai, J. Vogel, S. Pizzini, E. Martinez, A. Lamperti, J. B. Mohammedi, A. Laborieux, Y. Roussigne, Alexander Grutter, E. Arenholtz, Patrick Quarterman, Brian B. Maranville, S. Ono, M. Salah El Hadri, R. Tolley, E. E. Fullerton, L. Sanchez-Tejerina, A. Stashkevich, S. M. Cherif, A. D. Kent, D. Querlioz, J. Langer, B. Ocker, D. Ravelosona
The possibility to tune the Dzyaloshinskii Moriya interaction (DMI) by electric (E) field gating in ultra-thin magnetic materials has opened new perspectives in terms of controlling the stabilization of chiral spin structures. Most recent efforts have used

Optimal Bayesian Experimental Design

September 4, 2019
Author(s)
Robert D. McMichael
This manual describes an implementation of optimal Bayesian experimental design methods. These methods address routine measurements where data are fit to experimental models in order to obtain model parameters. The twin benefits of these methods are
