Direct kerr-frequency comb atomic spectroscopy

February 28, 2020
Author(s)
Liron Stern, Jordan R. Stone, Songbai Kang, Daniel C. Cole, Zachary L. Newman, Kerry Vahala
Microresonator-based soliton frequency combs- microcombs -have recently emerged to offer low- noise, photonic-chip sources for optical measurements. Owing to nonlinear-optical physics, microcombs can be built with various materials 1-3 and tuned or

SCAP Composer User Guide

February 28, 2020
Author(s)
Joshua Lubell
SCAP Composer is a software application for creating Security Content Automation Protocol (SCAP) source data stream collections from Extensible Markup Language (XML) documents valid with respect to schemas defined in SCAP component specifications. SCAP

Structure and Dynamics of Ethane Confined in Silica Nanopores in the Presence of CO 2

February 28, 2020
Author(s)
Tingting Liu, Siddharth Guatam, David R. Cole, Sumant Patankar, David Tomasko, Wei Zhou, Gernot Rother
Fundamental understanding of subcritical/supercritical behavior of key hydrocarbon species inside nanoporous matrices at elevated pressure and temperature is less developed compared to bulk fluids, but this knowledge is needed for efficient utilization of

The IEEE TC-10 Standards: Update 2019

February 28, 2020
Author(s)
Nicholas G. Paulter Jr., Sergio Rapuano, Luca De Vito, John R. Jendzurski, W. B. Boyer, S. J. Tilden
There is a global need to standardize the terms and the test and computational methods that are used to describe and/or measure the parameters that characterize and define the performance of devices that generate signals and subsequently measure and

The Need for Reliable Experimental Data in Computational Thermodynamics

February 28, 2020
Author(s)
Ursula R. Kattner
Computational methods have become indispensable tools for efficient development of new materials and their processing and have led to the new discipline of integrated computational materials engineering (ICME). The CALPHAD (calculation of phase diagrams)

Distributed Resource Allocation Schemes for Out-of-Coverage D2D Communications

February 27, 2020
Author(s)
Jian Wang, Richard A. Rouil, Fernando J. Cintron
In many public safety scenarios, Device-to-Device (D2D) communication should be capable of handling out-of-coverage situations, ensuring that D2D devices can communicate directly without the aid of network infrastructure. While a number of resource

On Upper Bounds for D2D Group Size

February 27, 2020
Author(s)
David W. Griffith, Aziza Ben Mosbah
In this paper, we examine the Physical Sidelink Discovery Channel (PSDCH) for out-of-coverage (OOC) Device-to-Device (D2D) Long Term Evolution (LTE) networks using direct discovery for User Equipments (UEs) that are half-duplex. We derive upper bounds for

The Thermal Character of a 1 m Methanol Pool Fire

February 27, 2020
Author(s)
Kunhyuk Sung, Jian Chen, Matthew Bundy, Marco G. Fernandez, Anthony Hamins
A series of measurements were made to investigate the thermal character of a 1 m diameter methyl alcohol (methanol; CH3OH) pool fire steadily burning with a constant lip height in a quiescent environment. The mass burning rate was measured by monitoring

Carrier mobility of silicon by sub-bandgap time-resolved terahertz spectroscopy

February 26, 2020
Author(s)
Timothy J. Magnanelli, Edwin J. Heilweil
Low density charge mobility from below bandgap, two-photon photoexcitation of bulk Silicon (Si) is interrogated using time-resolved terahertz spectroscopy (TRTS). Total charge mobility is measured as a function of excitation frequency and fluence (charge

Low energy cross section measurement of the 10B(a;n)13N reaction and its impact on neutron production in 1st generation stars

February 26, 2020
Author(s)
Q Liu, M Febbraro, R.J. deBoer, S. Aguilar, A Boeltzig, Y Chen, M Couder, J Gorres, Jamie Weaver, K. T. Macon, M. Wiescher, K. Manukyan, L. Morales, S Pain, W. A. Peters, C. Seymour, G. Seymour, R. Toomey, B. Vande Kolk
Nucleosynthesis in the fi rst generation of massive stars offer a unique setting to explore the creation of the fi rst heavier nuclei in an environment free of impurities from earlier stellar generations. In later generations of massive stars, hydrogen

Faster, More Accurate, Stack-Flow Measurements

February 25, 2020
Author(s)
Aaron N. Johnson, Iosif I. Shinder, Bernard J. Filla, Joey T. Boyd, Rodney A. Bryant, Michael R. Moldover, Thomaa D. Martz, Matthew Gentry
Exhaust flows from coal-fired electricity-generating-plants are determined by measuring the flue gas velocity at prescribed points in the stack cross section. These velocity measurements are made using EPA-approved differential pressure probes such as the
