March 4, 2019
Author(s)
Xiaolin Jiang, Zhibo Pang, Rick Candell, Dacfey Dzung, Michele Luvisotto, Carlo Fischione
Wireless communication is gaining popularity in industry for its simple deployment, mobility and low cost. Ultra low latency and high reliability requirements of mission critical industrial applications are highly demanding for wireless communication, and

COMPOSITION DETERMINATION OF LOW-PRESSURE GAS-PHASE MIXTURES BY 1H NMR SPECTROSCOPY

March 4, 2019
Author(s)
Chris Suiter, Mark O. McLinden, Thomas J. Bruno, Jason A. Widegren
1H NMR spectroscopy was used to analyze vapor-phase mixtures of methane and propane at low to moderate pressures. The mixtures were prepared gravimetrically and had low uncertainty in their composition. The primary mixture used for this work had a methane

Exploring Interfacial Exchange Coupling and Sublattice Effect in Heavy Metal/Ferrimagnetic Insulator Heterostructures using Hall Measurements, X-Ray Magnetic Circular Dichroism, and Neutron Reflectometry

March 4, 2019
Author(s)
Qiming Shao, Alexander Grutter, Yawen Liu, Guoqiang Yu, Chao-Yao Yang, Dustin A. Gilbert, Elke Arenholz, Padraic Shafer, Xiaoyu Chi, Chi Tang, Mohammed Aldosary, Aryan Navabi, Qing Lin He, Brian Kirby, Jing Shi, Kang L. Wang
Ferrimagnetic insulators (FMIs), such as rare-earth iron garnets, are of considerable interest for low-power spintronics due to low Gilbert damping and the absence of free charge carriers. FMIs are also promising candidate materials for high-frequency

Structural basis of CO2 adsorption in a flexible metal organic framework material

March 4, 2019
Author(s)
Andrew J. Allen, Winnie K. Wong-Ng, Eric J. Cockayne, Jeffrey T. Culp, Christopher Matranga
This paper reports the structural basis of CO2 adsorption in a representative model flexible metal organic framework (MOF) material, Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4] (NiBpene or PICNIC-60). NiBpene exhibits a CO2 sorption isotherm with

Use of Transition Models to Design High Performance TESs for the LCLS-II Soft X-Ray Spectrometer

Kelsey M. Morgan, Daniel T. Becker, Douglas A. Bennett, William B. Doriese, Johnathon D. Gard, K D. Irwin, Sang-Jun Lee, Dale Li, John A. Mates, Christine G. Pappas, Daniel R. Schmidt, Charles Titus, Daniel Van Winkle, Joel N. Ullom, Abigail L. Wessels, Daniel S. Swetz
We are designing an array of transition-edge sensor (TES) microcalorimeters for a soft X-ray spectrometer at the Linac Coherent Light Source at SLAC National Accelerator Laboratory to coincide with upgrades to the free electron laser facility. The complete

Improved Calculation Method for Insulation-based Fire Resistance of Composite Slabs

March 2, 2019
Author(s)
Jian Jiang, Adam L. Pintar, Jonathan M. Weigand, Joseph A. Main, Fahim Sadek
A calculation method for estimating the fire resistance of composite slabs with profiled steel decking according to the thermal insulation criterion is provided in Annex D of Eurocode 4 (EC4). In this study, comparisons between validated high-fidelity

Emerging Technology in Comparisons

March 1, 2019
Author(s)
Theodore V. Vorburger, Jun-Feng Song, Nicholas D. Petraco, Ryan Lilien
This chapter is designed to introduce the reader to emerging technologies relating to 3D surface topography measurement and comparative analysis. While the chapter includes several technical terms and a few equations, effort has been made to omit content

Engineering ClpS for Selective and Enhanced N-terminal Amino Acid Binding

March 1, 2019
Author(s)
Jennifer A. Tullman, Zvi Kelman, John P. Marino
One of the central challenges in the development of single-molecule protein sequencing technologies is achieving high-fidelity, sequential recognition and detection of specific amino acids that comprise the peptide sequence. An approach towards achieving

Chiehping Lai, Roy Sun, Camillo Gentile, Peter B. Papazian, Jian Wang, Jelena Senic
In this paper, we describe an extensive channel-measurement campaign - including 325 unique transmitter-receiver configurations - conducted in a lecture room with our 3D double- directional 60-GHz channel sounder. The receiver was mounted on a mobile robot

Metrological and legal traceability of time signals

March 1, 2019
Author(s)
Michael Lombardi, Demetrios Matsakis, Judah Levine
Metrological traceability requires an unbroken chain of calibrations that relate to a reference, with each calibration having a documented measurement uncertainty. In the field of time and frequency metrology, the desired reference is usually Coordinated
