Superconducting optoelectronic networks III: synaptic plasticity

July 5, 2018
Author(s)
Jeffrey M. Shainline, Adam N. McCaughan, Sonia M. Buckley, Christine A. Donnelly, Manuel C. Castellanos Beltran, Michael L. Schneider, Richard P. Mirin, Sae Woo Nam
As a means of dynamically reconfiguring the synaptic weight of a superconducting optoelectronic loop neuron, a superconducting flux storage loop is inductively coupled to the synaptic current bias of the neuron. A standard flux memory cell is used to

Universal Geometric Frustration in Pyrochlores

July 5, 2018
Author(s)
Benjamin A Trump, Syed M. Koohpayeh, Ken J. T. Livi, JiaJia Wen, Kathyrn Arpino, Quentin M. Ramasse, Rik Brydson, Mikhail Feygenson, H. Takeda, M. Takigawa, K. Kimura, S. Nakatsuji, Collin L. Broholm, T. M. McQueen
We report on the structural details of Pr 2Zr 2O 6O', La 2Zr 2O 6O', and Yb 2Ti 2O 6O' in the A 2B 2O 6O' pyrochlore structure. X-ray and neutron powder diffraction indicate these materials are long-range ordered. On the local scale these materials appear

Walk-through Metal Detector Testing and the Need to Emulate Natural Body Motion

July 5, 2018
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson, Nicklaus F. Troje
The effect of motion through the portal of a walk-through metal detector (WTMD) has often been considered to contribute to the uncertainty in detecting threat objects being carried through the WTMD. However, typical metrological testing uses a robotic

Electric-field control of perpendicular magnetic anisotropy in multiferroic PZT- and PMN- PT//[Co/Ni] composites with negative magnetostriction

July 4, 2018
Author(s)
Daniel B. Gopman, Andrew P. Chen, Cindi L. Dennis, June W. Lau, Robert D. Shull, Gregory P. Carman, Peter Finkel, Margo Staruch, Andres Chavez
A longstanding goal of spintronics is to identify alternatives to current-generated Oersted- fields for magnetization control at the nanoscale. An emerging approach seeks to harness the voltage-induced strain in a proximal piezostrictive layer to modify

Creating a Mass Spectral Reference Library for Oligosaccharides in Milk

July 3, 2018
Author(s)
Concepcion A. Remoroza, Tytus D. Mak, M. L. De Leoz, Yuri A. Mirokhin, Stephen E. Stein
We report the development and availability of a mass spectral reference library for oligosaccharides in human milk. This represents a new variety of spectral library that includes consensus spectra of compounds annotated through various data analysis

Local Quantum Phase Transition in YFe 2 Al^d10

July 3, 2018
Author(s)
W. J. Gannon, L. S. Wu, I. A. Zaliznyak, W. H. Xu, A. M. Tsvelik, Yiming Qiu, Jose Rodriguez Rivera, M. C. Aronson
A phase transition occurs when correlated regions of a new phase grow to span the system and the fluctuations within the correlated regions become long-lived. Here we present neutron scattering measurements showing that this conventional picture must be

Spin-Phonon Couplings in Transition Metal Complexes with Slow Magnetic Relaxation

July 3, 2018
Author(s)
Duncan H. Moseley, Shelby E. Stavretis, Komalavalli Thirunavukkuarasu, Mykhaylo Ozerov, Yongqiang Cheng, Luke L. Daemen, Jonathan Ludwig, Zhengguang Lu, Dmitry Smirnov, Craig Brown, Anup Pandey, A. J. Ramirez-Cuesta, Adam C. Lamb, Mihail Atanasov, Eckhard Bill, Frank Neese, Zi-Ling Xue
Co(acac) 2(H 2O) 2 (1, acac = acetylacetonate), a model transition metal complex, displays field-induced slow magnetic relaxation as a single-molecule magnet. Raman spectra of 1, Co(acac) 2(D 2O) 2 (1-d 4 and Co(acac-d 7) 2(D 2O 2) 2 (1-d 18) reveal that

Scheduling Policies in Flexible Bernoulli Lines with Dedicated Finite Buffers

July 2, 2018
Author(s)
Shaw C. Feng, Yuan Feng, Xiang Zhong, Wenhui Fan, Jingshan Li
This paper is devoted to studying scheduling policies in flexible serial lines with two Bernoulli machines and dedicated finite buffers. Priority, cyclic and work-in-process (WIP)-based scheduling policies are investigated. For small scale systems, exact

Characterization of Circulating Steroid Hormone Profiles in the Bottlenose Dolphin (Tursiops truncatus) by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS)

July 1, 2018
Author(s)
Thomas M. Galligan, Lori Schwacke, Dorian S. Houser, Randall Wells, Teresa Rowles, Ashley Russell
Circulating steroid hormone concentrations are typically measured by immunoassays, which have imperfect specificity and are limited to the measurement of a single hormone per assay. Here we demonstrate that reverse phase solid phase extraction (SPE)

Faster quantum algorithm to simulate Fermionic quantum field theory

July 1, 2018
Author(s)
Ali Hamed Moosavian, Stephen P. Jordan
In quantum algorithms discovered so far for simulating scattering processes in quantum field theories, state preparation is the slowest step. We present a new algorithm for preparing particle states to use in simulation of Fermionic Quantum Field Theory

Inelastic and Deep Inelastic Neutron Spectroscopy of Water Molecules under Ultra-Confinement

July 1, 2018
Author(s)
A. I. Kolesnikov, G. F. Reiter, Timothy R Prisk, M. Krzystyniak, G. Romanelli, D. J. Wesolowski, Lawrence M. Anovitz
Water confined within sub-nanometer channels of silicate minerals presents an extreme case of confinement, where the restricted molecules are situated in channels whose diameter is not much larger than the water molecule itself. Recently, we discovered a

Non-tunneling origin of the 1/f noise in SiC MOSFET

July 1, 2018
Author(s)
Kin (Charles) Cheung, Jason Campbell
Abstract: It has long been established that MOSFET random telegraph noise and the cumulative 1/f noise is the result of inversion charge tunneling in and out of bulk traps in the gate oxide near the interface. The tunneling nature is a key concept upon
