Diffusion Monte Carlo versus adiabatic computation for local Hamiltonians

February 15, 2018
Author(s)
Stephen P. Jordan, Jacob Bringewatt, Alan Mink, William Dorland
Most research regarding quantum adiabatic optimization has focused on stoquastic Hamiltonians, whose ground states can be expressed with only real, nonnegative amplitudes. This raises the question of whether classical Monte Carlo algorithms can efficiently

Wireless Infrastructure M2M Network For Distributed Power Grid Monitoring

October 1, 2017
Author(s)
Hamid Gharavi
With the massive integration of distributed renewable energy sources (RESs) into the power system, the demand for timely and reliable network quality monitoring, control, and fault analysis is rapidly growing. Following the successful deployment of Phasor

Lithographic sonication patterning of large area nanopillar forests

July 27, 2017
Author(s)
Joel C. Weber, Matthew D. Brubaker, Thomas M. Wallis, Kristine A. Bertness
This paper demonstrates a highly-scalable, material-independent method for patterning nanopillar forests known as lithographic sonication patterning. Through contact lithography, patterns with dimensions down to 3 υm were written across a 3-inch silicon

Structural Polymorphism in "Kesterite" Cu 2 ZnSnS 4 : Raman Spectroscopy and First-principles Calculations Analysis

March 20, 2017
Author(s)
Mirjana NMN Dimitrievska, Federica Boero, Alexander P. Litvinchuk, Simona Delsante, Gabriella Borzone, Alejandro Perez-Rodriguez, Victor Izquierdo-Roca
This work presents a comprehensive analysis of the structural and vibrational properties of the kesterite Cu 2ZnSnS 4 (CZTS, I-4 space group) as well as its polymorphs with the space group P-42c and P-42m, from both experimental and theoretical point of

Moment Method for Obtaining Particle Size Measures of Test Smokes

February 19, 2017
Author(s)
Thomas Cleary, D W. Weinert, George Mulholland
The number concentration, ionization chamber output, and mass concentration were recorded continuously for five different test smokes generated in the fire emulator/detector evaluator. The number and the mass concentrations are direct measures of the

Enabling photoemission electron microscopy in liquids via graphene-capped microchannel arrays

February 8, 2017
Author(s)
Hongxuan Guo, Evgheni Strelcov, Alexander Yulaev, Jian Wang, Narayana Appathurai, Stephen Urquhart, John Vinson, Subin Sahu, Michael P. Zwolak, Andrei Kolmakov
Photoelectron emission microscopy (PEEM) is a powerful tool to spectroscopically access dynamic surface processes at the nanoscale but is traditionally limited to ultra-high or moderate vacuum conditions. Here, we develop a novel graphene-capped

Characterizing Indoor Air- Quality Performance Using a Graphical Approach

March 8, 2016
Author(s)
Kevin Y. Teichman, Cynthia H. Reed, Steven J. Emmerich
In this paper, we describe and demonstrate a graphical approach to illustrating the indoor air quality (IAQ) performance of high-performing buildings. We start by describing previous efforts to establish IAQ and indoor environmental quality (IEQ) metrics

Precision and Robustness of 2D-NMR for Structure and Assessment of Filgrastim Biosimilars

February 5, 2016
Author(s)
Houman Ghasriani, Derek Hodgson, Robert G. Brinson, Ian McEwen, Lucinda F. Buhse, Steven Kozlowski, John Marino, Yves Aubin, David Keire
The higher order structure of biotherapeutics is a critical quality attribute (CQA) that can be evaluated by nuclear magnetic resonance (NMR) spectroscopy at atomic resolution. NMR spectral "fingerprinting" can directly establish drug substance structural
