An implementation in Julia of a library to make programmatically available the mass absorption and other data provided in the "X-Ray Form Factor, Attenuation, and Scattering Tables - NIST Standard Reference Database 66"

An implementation of the Bote-Salvat ionization cross-section parameterized algorithm for electron image up to 1 GeV. Based on * D. Bote and F. Salvat, "Calculations of inner-shell ionization by electron impact with the distorted-wave and plane-wave Born approximations", Phys. Rev. A77, 042701 (2008). * Bote, David, et al. "Cross sections for ionization of K, L and M shells of atoms by impact of electrons and positrons with energies up to 1 GeV: Analytical formulas." Atomic Data and Nuclear Data Tables 95.6 (2009): 871-909.

Provides information on population 3 years old and older on school enrollment, junior or regular college attendance, and high school graduation.

The NIST STEP to X3D Translator is open-source software that translates a STEP (ISO 10303) Part 21 file (.stp or .step) to an X3D (ISO/IEC 19776) file (.x3d) or X3DOM file (.html). Developed at the National Institute of Standards and Technology (NIST), the software is based on the Open CASCADE STEP Processor and written in C++.

This dataset provides industry statistics on number of establishments; number of employees; payroll; sales, value of shipments, or revenue; and other industry-specific data items by geographic area for establishments and firms with paid employees for Puerto Rico. Data are shown on a 2012 NAICS basis. The statistics, NAICS levels, and the geographic areas covered vary by sector. These data were released in December 2015.

The COVID-19 CDCS represents a metadata repository that provides a catalog of COVID-19 related research literature and data.

This data table contains the processed data for the LacI genotype-phenotype landscape, a quantitative measurement of the phenotype for approximately 60,000 variants of the E. coli LacI protein. The table includes, for example, the DNA barcode sequencing counts and the estimated fitness for each variant across 24 different chemical environments. It also includes the estimated dose-response curves for each variant under induction with IPTG.

Information on person and household broadband (high-speed Internet) use, where it is used, by what types of devices, what type of service provider, online actions performed, and other characteristics.

​The ITA Offices & Centers API provides contact and address information for all of ITA’s domestic and international offices. There are almost 200 ITA offices worldwide whose locations are managed by ITA’s internal office management system.

This dataset includes a Microsoft Excel spreadsheet (*.xlsx file) provided as supplemental material for the NIST Technical Note (TN-2099) publication titled "Quasi-Static Position Calibration of the Galvanometer Scanner on the Additive Manufacturing Metrology Testbed". The file contains two tabs, titled "Pre-Compensation" and "Post-Compensation", which provides example measurement data and calculations pertaining to the calibration procedures described in the publication.
