Materials Science in the AI age: high-throughput library generation, machine learning and a pathway from correlations to the underpinning physics

July 22, 2019
Author(s)
Kamal Choudhary, Aaron G. Kusne, Francesca M. Tavazza, Jason R. Hattrick-Simpers, Rama K. Vasudevan, Apurva Mehta, Ryan Smith, Lukas Vlcek, Sergei V. Kalinin, Maxim Ziatdinov
The use of advanced data analytics, statistical and machine learning approaches (‘AI’) to materials science has experienced a renaissance, driven by advances in computer sciences, availability and access of software and hardware, and a growing realization

A Classification Scheme for Wireless Channel Models Across the Development Life Cycle

July 12, 2019
Author(s)
David Michelson, Camillo Gentile, Nada T. Golmie, Jeanne Quimby, Kate Remley, Ken Gracie, Yvo de Jong
Wireless channel models play a critical role at all stages of the product life cycle, from standards development to network deployment. However, the distinctive needs and requirements for the channel models used at each stage of the cycle are rarely

Application of the group contribution volume translated Peng-Robinson equation of state to new commercial refrigerant mixtures

April 29, 2019
Author(s)
Ian H. Bell, Jonathan Welliquet, Maria Mondejar, Sylvain Quoilin, Ala Bazyleva, Frederik Haglind
The search of new refrigerants complying with the most recent environmental regulations must be supported by the availability of simple and reliable models for the prediction of their thermophysical behavior, both as pure substances and as mixtures. Cubic

A Comparison Between The Solution Properties of Knotted Ring and Star Polymers

October 31, 2018
Author(s)
Luis F. Vargas Lara, Beatriz Pazmino, Jack F. Douglas
We computationally investigate the solution properties of knotted flexible ring and star polymers by combining molecular dynamics simulation (MD) and path-integral calculations. In particular, we consider knotted rings having a minimal crossing number mc

IT Asset Management : Financial Services

September 7, 2018
Author(s)
James M. Banoczi
While a physical asset management system can tell you the location of a computer, it cannot answer questions like, “What operating systems are our laptops running?” and “Which devices are vulnerable to the latest threat?” An effective IT asset management

Pseudorandom Quantum States

August 19, 2018
Author(s)
Yi-Kai Liu, Zhengfeng Ji, Fang Song
We propose the concept of pseudorandom quantum states, which appear random to any quantum polynomial-time adversary. It offers a computational approximation to perfectly random quantum states (analogous to cryptographic pseudorandom generators), as opposed

Aqueous Ion trapping and transport in graphene-embedded 18-crown-6 ether pores

June 25, 2018
Author(s)
Alexander Smolyanitsky, Eugene Paulechka, Kenneth Kroenlein
Using extensive room-temperature molecular dynamics simulations, we investigate selective aqueous cation trapping and permeation in graphene-embedded 18-crown-6 ether pores. We show that in the presence of suspended water-immersed crown-porous graphene, K+

A Metal-Organic Framework with Optimized Porosity and Functional Sites for High Gravimetric and Volumetric Methane Storage Working Capacities

April 24, 2018
Author(s)
Hui-Min Wen, Bin Li, Libo Li, Rui-Biao Lin, Wei Zhou, Guodong Qian, Banglin Chen
Extensive research has been devoted to develop new porous materials for high methane storage capacity. While great progress has been made in recent years, it still remains very challenging to target simultaneously high gravimetric and volumetric methane

Modeling the polarized X-ray scattering from periodic nanostructures with molecular anisotropy

December 1, 2017
Author(s)
Christopher D. Liman, Thomas A. Germer, Daniel F. Sunday, Dean M. DeLongchamp, Regis J. Kline
We discuss a new technique to measure molecular orientation in nanostructures using resonant soft X-rays. This technique is based on a variable angle transmission measurement called critical dimension X-ray scattering that enables the characterization of

Towards Probabilistic Identification of Zero-day Attack Paths

October 24, 2017
Author(s)
Xiaoyan Sun, Dai Jun, Peng Liu, Anoop Singhal, John Yen
Zero-day attacks continue to challenge the enterprise network security defense. A zero-day attack path is formed when a multi- step attack contains one or more zero-day exploits. Detecting zero-day attack paths in time could enable early disclosure of zero

Evaluating the Effects of Modeling Errors for Isolated Finite 3-D Targets

October 19, 2017
Author(s)
Mark Alexander Henn, Bryan M. Barnes, Hui Zhou
Optical 3-D nanostructure metrology utilizes a model-based metrology approach to determine critical dimensions (CDs) that are well below the inspection wavelength. Our project at the National Institute of Standards and Technology is evaluating how to

Tools for annotation and comparison of structural variation

October 3, 2017
Author(s)
Justin M. Zook, Fritz Sedlazeck, Andi Dhroso, Justin Paschall
The impact of structural variants (SVs) on a variety of organisms and diseases like cancer has become increasingly evident. Methods for SV detection when studying genomic differences across cells, individuals or populations are being actively developed

Verification and Test Methods for Access Control Policies/Models

June 27, 2017
Author(s)
Chung Tong Hu, David R. Kuhn, Dylan J. Yaga
Access control systems are among the most critical of computer security components. Faulty policies, misconfigurations, or flaws in software implementations can result in serious vulnerabilities. To formally and precisely capture the security properties

Energy Escalation Rate Calculator (EERC1.0-03)

February 19, 2017
Author(s)
L I. Schultz, S Fuller
The Energy Escalation Rate Calculator (EERC) computes an average annual escalation rate for fuel prices, based on the annual energy price forecasts of the Energy Information Administration (EIA) of the U.S. Department of Energy (DOE). This rate is used to

Predictive chemical kinetic model for lubricant performance: bench testings

February 19, 2017
Author(s)
Stephen M. Hsu, C I. Chen
Bench tests have been used to screen lubricants and additives for industrial fluids in machinery applications for a very long time. As technology becomes more sophisticated in terms of materials, controls, and design, the need for simple, quick, and cheap
