Dataset of Published Concentrations of Plastic Additives in the Ocean

Data provided by  National Institute of Standards and Technology

Concentrations of plastic additive chemicals were taken from peer-reviewed literature. Only studies that mentioned the chemicals as plastic additives were included. Studies that measured plastic additives in marine plastic debris, marine organisms, marine sediments and/or seawater were included.

Text Retrieval Conference (TREC) Total Recall collections

Data provided by  National Institute of Standards and Technology

This data was used in the TREC 2015 and 2016 total recall track. The goal of the total recall track was to help develop retrieval systems tuned to retrieving ALL relevant information, as opposed to common web search engines where one good answer could be sufficient.

On-Wafer Calibration Comparisons of Multiline TRL with Platinum and Gold Conductors

Data provided by  National Institute of Standards and Technology

Here are included figures and other relevant data from the paper "On-Wafer Calibration Comparisons of Multiline TRL with Platinum and Gold Conductors" to be published in International Microwave Symposium 2024.Introduction: On-wafer calibrations are critical for measurements of embedded devices at the correct reference planes. A major challenge in on-wafer calibrations is the development of accurate calibrations that cover a frequency range from MHz to THz. Another challenge facing on-wafer measurements is the lack of calibrations that are directly traceable to the SI.

Interlaboratory Measurement of Adeno-Associated Virus:Comparative Quantification of Full and Empty Capsids

Data provided by  National Institute of Standards and Technology

Summary Data For Interlaboratory Study on Adeno-Associated Virus Particles. This contains all the data to be published in a journal article detailing the measurement of full-to-total ratio by analytical ultracentrifugation, size exclusion chromatography-multiangle light scattering, polymerase chain reaction, and ultraviolet spectrophometry. Samples here consisted of nominally 100% full particles, nominally 0% full particles, and a 50:50 mixture of the two.

Raw data from NIST-led interlaboratory study on the working curve in vat photopolymerization

Data provided by  National Institute of Standards and Technology

Raw data from interlaboratory study on the working curve (Link to publication here: ). Each dataset has a header indicating the nominal wavelength and intensity of the light engine used to measure the working curve. Each file contains paired radiant exposure (in units of mJ/cm2) and cure depth (in units of µm) measurements provided by participants.

Data for Filtering Organized 3D Point Clouds for Bin Picking Applications

Data provided by  National Institute of Standards and Technology

Contains scans of a bin filled with different parts ( screws, nuts, rods, spheres, sprockets). For each part type, RGB image and organized 3D point cloud obtained with structured light sensor are provided. In addition, unorganized 3D point cloud representing an empty bin and a small Matlab script to read the files is also provided. 3D data contain a lot of outliers and the data were used to demonstrate a new filtering technique.

Using Open-Path Dual-Comb Spectroscopy to Monitor Methane Emissions from Simulated Grazing Cattle

Data provided by  National Institute of Standards and Technology

Data published in the paper "Using Open-Path Dual-Comb Spectroscopy to Monitor Methane Emissions from Simulated Grazing Cattle". A controlled methane release experiment was performed to determine if dual comb spectroscopy (DCS) can detect methane concentration enhancements above the atmospheric background produced by a typical herd of beef cattle in an extensive grazing system. Open-path DCS was used to measure downwind and upwind methane concentrations from ten point-sources of methane simulating cattle.

Code for "An atomic boson sampler"

Data provided by  National Institute of Standards and Technology

This package is a collection of scripts and methods for analyzing data from the Kaufman lab's experiment for boson sampling using atoms, tunneling in their optical lattice.Please read the paper [arXiv:2307.06936](https://doi.org/10.48550/arXiv.2307.06936) for context.The data included in the subdirectory ``Boson sampling data/`` consists of shots of the experiment, where the atoms are prepared in a particular pattern,then the atoms are allowed to tunnel, then the atom number parity is measured on each site.From this data, we estim

Code for qDIC-based Strain Localization Analysis with Wavelets (Q-SLAW)

Data provided by  National Institute of Standards and Technology

This dataset is an archival version of an algorithm implementation for strain localization analysis in digital image correlation data. The original application is to detect the occurrence of localization (i.e., collective buckling, hotspots, etc.) in uniaxial stress testing of polymer foams instrumented with 2D digital image correlation. The full-field strain maps are processed with a Marr wavelet and regions of excess strain are identified.
