Optimization of Folch, Bligh-Dyer, and Matyash Sample-to-Extraction Solvent Ratios for Mammalian Cell- and Plasma-Based Lipidomics Studies

December 11, 2018
Author(s)
John Bowden, Candice Z. Ulmer, Christina Jones, Richard A. Yost, Timothy J. Garrett
In order to investigate changes in the lipidome, analysis by ultra-high performance liquid chromatography - high resolution mass spectrometry (UHPLC-HRMS) typically requires the extraction of lipid content from sample matrices using optimized, matrix

A post-processing-free single-photon random number generator with ultra-low latency.

December 10, 2018
Author(s)
Michael A. Wayne, Joshua C. Bienfang, Zachary H. Levine, Alan L. Migdall
The low-latency requirements of a practical loophole-free Bell test preclude time-consuming post- processing steps that are often used to improve the statistical quality of a physical random number generator (RNG). Here we demonstrate a post-processing

Controlling the polarization and vortex charge of attosecond high-harmonic beams via simultaneous spin-orbit momentum conservation

December 10, 2018
Author(s)
Kevin Dorney, Laura Rego, Nathan J. Brooks, Julio San Roman, Chen-Ting Liao, Jennifer Ellis, Dmitriy Zusin, Christian Gentry, Quynh Nguyen, Justin Shaw, Antonio Picon, Luis Plaja, Henry C. Kapteyn, Margaret M. Murnane, Carlos Hernandez-Garcia
Optical interactions are governed by both spin and angular momentum conservation laws, which serve as a tool for controlling light-matter interactions or elucidating electron dynamics and structure of complex systems. Here, we uncover a form of

Electric field induced phase transition in vertical MoTe2 and Mo1-xWxTe2 based RRAM devices

December 10, 2018
Author(s)
Feng Zhang, Sergiy Krylyuk, Huairuo Zhang, Cory A. Milligan, Dmitry Y. Zemlyanov, Leonid A. Bendersky, Albert Davydov, Joerg Appenzeller, Benjamin P. Burton, Yugi Zhu
Transition metal dichalcogenides have attracted attention as potential building blocks for various electronic applications due to their atomically thin nature and polymorphism. Here, we report an electric-field-induced structural transition from a 2H

Kinetic Inductance Traveling Wave Amplifiers For Multiplexed Qubit Readout

December 10, 2018
Author(s)
Leonardo Ranzani, K. C. Fong, G. Ribell, Tomas A. Ohki, David P. Pappas, Mustafa Bal, Xian Wu, Robert P. Erickson, Junling Long, Hsiang S. Ku
We describe a kinetic inductance traveling-wave (KIT) amplifier suitable for superconducting quantum information measurements and characterize its wideband scattering and noise properties. We use mechanical microwave switches to calibrate the four

COMPARISON OF DATA ANALYTICS APPROACHES USING SIMULATION

December 9, 2018
Author(s)
Sanjay Jain, Anantha Narayanan Narayanan, Yung-Tsun Lee
Selecting the right data analytics (DA) approach for an application is rather complex. Obtaining sufficient and right kind of data for evaluating these approaches is a challenge. Simulation models can support this process by generating synthetic data where

EMC and Metrology Challenges for 5G and Beyond

December 7, 2018
Author(s)
Perry F. Wilson, Catherine A. Remley, William F. Young, Camillo A. Gentile, John M. Ladbury, Dylan F. Williams
The potential to connect people and devices anywhere and anytime is driving the development and deployment of a multitude of wireless systems. Wireless connectivity is central to advanced communication technologies, the internet of things (IoT), the smart

Millimeter-Wave Channel Measurement and Modeling: A NIST Perspective

December 7, 2018
Author(s)
Camillo A. Gentile, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley, Peter G. Vouras, Jelena Senic, Jian Wang, Jack Chuang, Ruoyu Sun
The exponential increase in wireless data transmission from smartphones has led to the saturation of the sub-6-GHz bands, forcing cellular providers to migrate to the millimeter-wave (mmWave) regime for 5G. Although available channel bandwidths will grow

Millimeter-Wave Propagation Channels vs. Synthetic Beamwidth

December 7, 2018
Author(s)
Roy Sun, Camillo A. Gentile, Jelena Senic, Peter G. Vouras, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley
High-gain narrow-beam antennas or beamformed antenna arrays will likely be used in millimeter- wave (mmWave) bands and 5G to mitigate the high path loss. Since many multipath components may be excluded by the narrow beam, the mmWave propagation channels

Atomic clock performance beyond Earths gravitational limit

December 6, 2018
Author(s)
William F. McGrew, Xiaogang Zhang, Robert J. Fasano, Stefan A. Schaeffer, Kyle P. Beloy, Daniele Nicolodi, Roger C. Brown, N. Hinkley, G. Milani, Marco Schioppo, T. H. Yoon, Andrew D. Ludlow
The passage of time is tracked by counting oscillations of a suitable frequency reference (e.g., the number of revolutions of Earth around the sun or the number of swings of a pendulum of a grandfather clock). By referencing the oscillations arising from

Automation Support for Security Control Assessments: Software Asset Management

December 6, 2018
Author(s)
Kelley L. Dempsey, Nedim S. Goren, Paul Eavy, George Moore
The NISTIR 8011 volumes focus on each individual information security capability, adding tangible detail to the more general overview given in NISTIR 8011 Volume 1, and providing a template for transition to a detailed, NIST standards-compliant automated

Influence of Nanofluid Instability on Thermodynamic Properties near the Critical Point

December 6, 2018
Author(s)
Joe W. Magee, Nikolai Polikhronidi, Rabiyat Batyrova, Ilmutdin Abdulagatov
Thermodynamic properties (isochoric heat capacity, critical and phase transition temperatures, pressure and thermal-pressure coefficient) of nanofluid (2-propanol+TiO2) were experimentally studied near the critical point of the pure base fluid (2-propanol)
