ICSSC Biennial Progress Report for 2018: Report on Progress Towards Implementation of Executive Order 13717: Establishing a Federal Earthquake Risk Management Standard - Reporting Period: February 2, 2016 to February 1, 2018

October 21, 2021
Author(s)
John Harris, Katherine Johnson, Steven McCabe
On February 2, 2016, President Obama signed Executive Order (EO) 13717: Establishing a Federal Earthquake Risk Management Standard. The EO establishes a minimum level of seismic safety compliance for new and existing buildings that will be constructed

X-Ray Spectroscopy and Calibrations in the 50 eV to 60 keV Range

October 12, 2021
Author(s)
J Seely, Uri Feldman, J. Weaver, Lawrence T. Hudson
Spectrometers have been developed to record x-ray spectra in the energy range 50 eV to 60 keV. The dispersion elements are transmission crystals for energies higher than approximately 11 keV, reflection crystals for 1 keV to 20 keV, and transmission

Chromosome-scale, haplotype-resolved assembly of human genomes

December 7, 2020
Author(s)
Justin Zook, Shilpa Garg, Heng Li
Haplotype-resolved or phased genome assembly provides a complete picture of genomes and their complex genetic variations. However, current algorithms for phased assembly either do not generate chromosome-scale phasing or require pedigree information, which

Atomic Transition Probabilities of AluminumA Critical Compilation

November 14, 2018
Author(s)
Daniel E. Kelleher, Larissa Podobedova
This compilation is the second in a series of updates to Atomic Transition Probabilities, Sodium through Calcium, published in 1969 by W. L. Wiese et al. Atomic transition probabilities have been critically evaluated and compiled for about 5000 spectral

Atomic Transition Probabilities of SiliconA Critical Compilation

Author(s)
Daniel E. Kelleher, Larissa Podobedova
This compilation is the third in a series of updates to Atomic Transition Probabilities, Sodium through Calcium, published in 1969 by W. L. Wiese et al. Atomic transition probabilities have been critically evaluated and compiled for about 5800 spectral

SARD: Thousands of Reference Programs for Software Assurance

October 31, 2017
Author(s)
Paul E. Black
A corpus of computer programs with known bugs is useful in determining the ability of tools to find bugs. This article describes the content of NIST's Software Assurance Reference Dataset (SARD), which is a publicly available collection of thousands of

Spectrum and Energy Levels of Four-Times Ionized Yttrium (Y V

December 21, 2016
Author(s)
Joseph Reader
We present an extended analysis of the spectrum of four-times-ionized yttrium Y V. The analysis is based on spectrograms made with sliding-spark discharges on 10.7 normal- and grazing-incidence spectrographs. The measurements cover the region 184-2549 Å

A Logic Based Network Forensics Model for Evidence Analysis

January 28, 2015
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Many attackers tend to use sophisticated multi-stage and/or multi-host attack techniques and anti-forensic tools to cover their traces. Due to the limitations of current intrusion detection and network forensic analysis tools, reconstructing attack

Influence of Metal?MoS2 Interface on MoS2 Transistor Performance: Comparison of Ag and Ti Contacts

December 16, 2014
Author(s)
Hui H. Yuan, Guangjun Cheng, Lin You, Haitao Li, Hao Zhu, Wei Li, Joseph J. Kopanski, Yaw S. Obeng, Angela R. Hight Walker, David J. Gundlach, Curt A. Richter, D. E. Ioannou, Qiliang Li
In this work, we present a study of enhancing MoS2 transistor performance by using proper metal contact. We found that the on-state current of MoS2 field-effect transistors with 30 nm Au/ 30 nm Ag contacts is enhanced more than 60 times and the

Componentization in the Systems Modeling Language

November 20, 2013
Author(s)
Conrad E. Bock
This paper describes new capabilities in the Systems Modeling Language that reduce the complexity of specifying systems through componentization, and increase the range of systems that can be specified. Modelers can identify portions of components

Wide Angle Polarization Analysis with Neutron Spin Filters

Qiang NMN Ye, Thomas R. Gentile, Jeffrey R. Anderson, Collin L. Broholm, WangChun Chen, Z DeLand, Ross W. Erwin, C. B. Fu, John E. Fuller III, Aaron V. Kirchhoff, J. A. Rodriguez-Rivera, V. Thampy, T G. Walker, Shannon Watson
We report substantial improvements in a compact wide angle neutron spin filter system that was recently employed on the Multi-Axis Crystal Spectrometer at the Center for Neutron Research at the U.S. National Institute of Standards and Technology. The

New Equations for the Sublimation Pressure and Melting Pressure of H2O Ice Ih

December 17, 2011
Author(s)
Wolfgang Wagner, T Riethmann, Rainer Feistel, Allan H. Harvey
New reference equations, adopted by the International Association for the Properties of Water and Steam (IAPWS), are presented for the sublimation pressure and melting pressure of ice Ih as a function of temperature. These equations are based on input

The Development of an Aerodynamic Shoe Sampling System

November 15, 2011
Author(s)
Matthew E. Staymates, Jessica M. Grandner, John G. Gillen, Stefan Lukow
In collaboration with the Transportation Security Laboratory, the National Institute of Standards and Technology has been developing a prototype shoe sampling system that relies on aerodynamic sampling for liberating, transporting, and collecting explosive

BEES Online: Life Cycle Analysis for Building Products

September 30, 2010
Author(s)
Barbara C. Lippiatt, Anne L. Greig, Priya D. Lavappa
The BEES (Building for Environmental and Economic Sustainability) Online web application implements a rational, systematic technique for selecting environmentally-preferred, cost-effective building products. The technique is based on consensus standards
