2022 American Community Survey: 5-Year Estimates - Public Use Microdata Sample

Data provided by  United States Census Bureau

The American Community Survey (ACS) Public Use Microdata Sample (PUMS) contains a sample of responses to the ACS. The ACS PUMS dataset includes variables for nearly every question on the survey, as well as many new variables that were derived after the fact from multiple survey responses (such as poverty status).Each record in the file represents a single person, or, in the household-level dataset, a single housing unit. In the person-level file, individuals are organized into households, making possible the study of people within the contexts of their families and other household members.

2022 American Community Survey: 5-Year Estimates - Public Use Microdata Sample Puerto Rico

Data provided by  United States Census Bureau

The Public Use Microdata Sample (PUMS) for Puerto Rico (PR) contains a sample of responses to the Puerto Rico Community Survey (PRCS). The PRCS is similar to, but separate from, the American Community Survey (ACS). The PRCS collects data about the population and housing units in Puerto Rico. Puerto Rico data is not included in the national PUMS files. It is published as a state equivalent file and has a State FIPS code of "72".

Data to support "Implementation of SPME and Rapid GC-MS as a Screening Approach for Forensic Fire Debris Applications"

Data provided by  National Institute of Standards and Technology

This data set contains raw data files for ignitable liquids, mock fire debris samples, and other related samples. All samples were extracted using solid phase microextraction (SPME) and analyzed by rapid gas chromatography-mass spectrometry (GC-MS), a recently developed chromatographic screening technique. Data is included for instrument inlet optimization, analysis of neat ignitable liquids (gasoline and diesel fuel), and analysis of mock burn samples consisting of carpet and wood substrates spiked with either ignitable liquid.

Flow visualization of gunshot residue plumes from handguns.

Data provided by  National Institute of Standards and Technology

This video content contains flow visualization footage of the plume dynamics generated during the discharge of a Springfield 9mm handgun. The gun range is a modified 12 m (40 ft) sea cargo container specifically designed for handheld firearms research and includes an advanced air filtration system that can be turned on or off. The air filtration system is off during these experiments. In each video, a laser light-sheet is positioned either horizontally or vertically and bisects the barrel of the firearm.

Activation loop plasticity and active site coupling in the MAP kinase, ERK2: Supplementary Data, Trajectories, and Scripts

Data provided by  National Institute of Standards and Technology

Conventional molecular dynamics (MD) simulations using the GPU-enabled CUDA version of the pmemd executable (pmemd.cuda) in AMBER were applied to explore the structure and dymanics of MAPK, ERK2. The role of dual phosphorylation was explored by comparing 0P-ERK2 with 2P-ERK2 (two phosphate groups added at T183 and Y185). Both 0P-ERK2 and 2P-ERK2 models were treated with the ff19SB forcefield immersed in a solution of 0.15 M NaCl in OPC water. The results showed that the A-loop can adopt multiple long-lived (>5 microseconds) conformational states.

A Sensitivity Analysis of Methodological Variables Associated with Microbiome Measurements

Data provided by  National Institute of Standards and Technology

This repository provides the raw data, analysis code, and results generated during a systematic evaluation of the impact of selected experimental protocol choices on the metagenomic sequencing analysis of microbiome samples. Briefly, a full factorial experimental design was implemented varying biological sample (n=5), operator (n=2), lot (n=2), extraction kit (n=2), 16S variable region (n=2), and reference database (n=3), and the main effects were calculated and compared between parameters (bias effects) and samples (real biological differences).
