A Science Gateway for Atomic and Molecular Physics

January 7, 2020
Author(s)
Barry I. Schneider, Klaus Bartschat, Oleg Zatsarinny, Igor Bray, Fernando Martin, Armin Scrinzi, Sudhakar Pamidighantam, Jonathan Tennyson, Jimena Gorfinkiel, Markus Klinker
We describe the creation of a new Atomic and Molecular Physics science gateway (AMPGateway). The gateway is designed to bring together a subset of the AMP community to work collectively to make their codes available and easier to use by the partners as

Efficient Randomness Certification by Quantum Probability Estimation

January 7, 2020
Author(s)
Emanuel H. Knill, Yanbao Zhang, Honghao Fu
For practical applications of quantum randomness generation, it is important to produce a fixed block of fresh random bits with as few trials as possible. Consequently, protocols with high finite-data are preferred. In this work we develop a broadly

Structural and Reorientational Dynamics of Tetrahydroborate (BH 4 -) and Tetrahydrofuran (THF) in a Mg(BH 4 ) 2 &#82263THF Adduct: Neutron-Scattering Characterization

January 7, 2020
Author(s)
Mirjana NMN Dimitrievska, Marina Chong, Mark E. Bowden, Hui Wu, Wei Zhou, Iffat Nayyar, Bojana Ginovska, Thomas Gennett, Tom Autrey, Craig M. Jensen, Terrence J. Udovic
Metal borohydrides are considered as promising materials for hydrogen storage applications due to their high volumetric and gravimetric hydrogen densities. Recently, different solvents have been complexed with Mg(BH 4) 2 in efforts to improve its

Covariance-based uncertainty analysis of reference equations of state

January 6, 2020
Author(s)
Howard Cheung, Jerome Frutiger, Ian Bell, Jens Abildskov, Gurkan Sin, Shengwei Wang
This work presents a detailed methodology for uncertainty analysis applied to a reference equation of state (EOS) based on Helmholtz energy. With increasing interest in uncertainties of thermal process models, it is important to quantify the property

Forensic Analysis of Advanced Persistent Threat Attacks in Cloud Environments

January 6, 2020
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Due to the increasing cyber-activities and the use of diverse devices offered on cloud environments, post-attack cloud forensic investigations must deal with data in diverse formats and quantities from emerging attackable interfaces. The process of

Focused Ion Beam-Induced Displacive Phase Transformation From Austenite to Martensite during Fabrication of Quenched and Partitioned Steel Micro-Pillar

January 5, 2020
Author(s)
Eun Jung Seo, Lawrence Cho, Jin Kyung Kim, Javad Mola, Lijia Zhao, Sukjin Lee, Bruno C. De Cooman
We report evidence of displacive phase transformation from retained austenite to martensite during preparation of quenched and partitioned steel micro-pillars by using focused ion beam (FIB) technique. The BCC phase produced by the FIB damage was

Quantifying protein aggregation kinetics using electrospray differential mobility analysis

January 5, 2020
Author(s)
Kaleb J. Duelge, Jeremie Parot, Vincent A. Hackley, Michael R. Zachariah
Protein aggregation is a significant concern in bioprocessing and end use applications. Here the thermal aggregation kinetics of bovine serum albumin (BSA) and α-chymotrypsinogen A (α- chymo) were measured over a range of concentrations and temperatures by

Development of an LC-APCI-MS Method for Determining Off-Flavor Compounds and its Application Towards Marine Recirculating Aquaculture System Monitoring and Evaluation of Aeration as a Depuration Approach

January 4, 2020
Author(s)
Mary Bedner, Keiko Saito
The off-flavor compounds geosmin and 2-methylisoborneol (2-MIB) are well-known to impact the quality of farmed freshwater fish species, but little is known about off-flavors in marine aquaculture. To begin addressing this knowledge gap, a method for the

BowTie - a deep learning feedforward neural network for sentiment analysis

January 3, 2020
Author(s)
Apostol T. Vassilev
How to model and encode the semantics of human-written text and select the type of neural network to process it are not settled issues in sentiment analysis. Accuracy and transferability are critical issues in machine learning in general. These properties

Demonstration of 220/280 GHz Multichroic Feedhorn-Coupled TES Polarimeter

January 3, 2020
Author(s)
Samantha L. Walker, Carlos E. Sierra, Jason E. Austermann, James A. Beall, Daniel T. Becker, Bradley J. Dober, Shannon M. Duff, Gene C. Hilton, Johannes Hubmayr, Jeffrey L. Van Lanen, Jeff McMahon, Sara M. Simon, Joel N. Ullom, Michael R. Vissers
We describe the design and measurement of feedhorn-coupled, transition-edge sensor (TES) polarimeters with two passbands centered at 220 GHz and 280 GHz, intended for observations of the cosmic microwave background. Each pixel couples polarized light in

Dynamical evolution of the 2D/3D interface: a hidden driver behind perovskite solar cell instability

January 3, 2020
Author(s)
Lee J. Richter, Ahmad R. Kirmani, Albertus A. Sutano, Nikita Drigo, Ines G. Benito, Valentine I. Queloz, Kyung T. Cho, Pascal A. Schouwink, Mohammad K. Nazeeruddin, Giulia Grancini, Sanghyun Paek
Engineering two-/three-dimensional (2D/3D) perovskite solar cells is nowadays a popular strategy for efficient and stable devices. However, the exact function of the 2D/3D interface in controlling the long-term device behavior is still obscure. Here, we

Plasmonic Nano-antenna Optimization Using Characteristic Mode Analysis

January 3, 2020
Author(s)
Edward Garboczi, Sumitra Dey, Deb Chatterjee, Ahmed M. Hassan
Plasmonic nano-antennas are typically designed using RF-inspired parametric optimization process and/or using trial and error search algorithms which lack proper physical insight. In this study, we demonstrate how the Characteristic Mode Analysis (CMA)

Utica Shale Reactivity: CO2 Induced Pore Scale Changes in the Fracture Network and Matrix

January 3, 2020
Author(s)
Angela Goodman, Sean Sanguinito, Sittichai Natesakhawat, Patricia Cvetic, Barbara Kutchko, Andrew J. Allen
The Utica Shale is expected to be a substantial fossil fuel resource in the future. Currently, 663.5 billion cubic feet of natural gas and oil are being produced from the Utica in Eastern Ohio. In this work, we examined the Utica Shale and its reactivity
