Data for "Increased Efficiency in Planar Near-Field Scanning Using Combined Multi-Robot Motion"

Data provided by  National Institute of Standards and Technology

Included here is relevant data to the publication "Increased Efficiency in Planar Near-Field Scanning Using Combined Multi-Robot Motion". Robotic antenna ranges are highly configurable, but traditional pose selection methods do not utilize the collaborative capability presented by these positioners. We present methods to reduce measurement time during planar scanning on robotic antenna ranges with redundant actuation.

H3O+ PTR-MS PID Library

Data provided by  National Institute of Standards and Technology

The H3O+ PTR-MS PID Library is a collection of product ion distributions (PID) from volatile organic compounds measured from proton-transfer-reaction mass spectrometers (PTR-MS). This library contains PID measurements that PTR-MS users can use to understand possible measurement interferences. This library is intended to be updated with continued input from users. This library is a supplementary document to the manuscript "Product Ion Distributions using H3O+ PTR-ToF-MS: Mechanisms, Transmission Effects, and Instrument-to-Instrument Variability".

TREC 2001 CROSS LANGUAGE DATASET

Data provided by  National Institute of Standards and Technology

Ten groups participated in the TREC-2001 cross-language information retrieval track, which focussed on retrieving Arabic language documents based on 25 queries that were originally prepared in English. French and Arabic translations of the queries were also available.

Trojan Detection Software Challenge - rl-colorful-memory-sep2024-train

Data provided by  National Institute of Standards and Technology

This is the training data used to create and evaluate trojan detection software solutions. This data, generated at NIST, consists of RL agents operating in the Colorful Memory environment. A known percentage of these trained AI models have been poisoned with a known trigger which induces incorrect behavior. This data will be used to develop software solutions for detecting that trigger behavior in the trained AI models.

Next Generation Sequences for Wild-caught Coho Salmon (RM 8256): Nucleotide sequences and their quality scores recorded in a FASTQ file obtained via Next Generation sequencing of mitochondrial DNA extracted from Coho salmon

Data provided by  National Institute of Standards and Technology

Closely related species of Salmonidae, including Pacific and Atlantic salmon, can be distinguished from one another based on nucleotide sequences from the cytochrome c oxidase sub-unit 1 mitochondrial gene (CO1), using ensembles of short-reads aligned to genetic barcodes that serve as digital proxies of the relevant species. This is accomplished by exploiting both the nucleotide sequences and their quality scores recorded in a FASTQ file obtained via Next Generation sequencing of mitochondrial DNA extracted from Coho salmon caught with hook and line in the Gulf of Alaska.

Measuring Microbial Community-Wide Antibiotic Resistance Propagation via Natural Transformation in the Human Gut Microbiome

Data provided by  National Institute of Standards and Technology

This repository includes the raw data, analysis code, and results of a systematic analysis of natural transformation (i.e., horizontal gene transfer; HGT) of bacteria in a naturally occurring microbiome (human stool) following exposure to free extracellular DNA (eDNA) that coded for antibiotic resistance. A full description of this effort is available in the associated publication.

C-V2X Interoperability Testing Datasets

Data provided by  National Institute of Standards and Technology

These datasets contain C-V2X network communication and interoperability testing packet data collected using a network sniffer (Wireshark) in the Packet Capture (PCAP) format and converted into the Packet Description Markup Language (PDML) format. These datasets include three testcases: C-V2I, C-V2V, and C-V2X. These datasets can be used to display, analyze, and assess C-V2X compatibility and interoperability among commercial on-board units (OBUs) and road-side units (RSUs) based on IEEE 1609.2, IEEE 1609.3, and SAE J2735 standards.
