The SP-2 experiment on the Vega spacecraft studied the spatial and mass distributions of dust particles in a cometary coma. The data likely covers a mass range from 1.e-16 to 1.e-6 grams using impact plasma and acoustic sensors. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
A collection of ground irradiance data collected for validating optical models of vertically-oriented bifacial photovoltaic systems, particularly in agrivoltaic applications. It was compiled by researchers for a study on vertical PV system model validation across various orientations and latitudes. The data is provided as open source by the Department of Energy.
Historical gold price data for the Indian state of Tamil Nadu from January 2006 to September 2020. The dataset includes daily prices for Pure Gold (24 k) and Standard Gold (22 k) in Indian Rupees, organized by date, country, state, and city. Data was scraped from the website www.livechennai.com.
Water temperature and derived turbulence quantities measured by chipod thermistor chain instruments on a Tropical Atmosphere Ocean (TAO) Array mooring at 0N, 110W in the equatorial Pacific Ocean. The dataset spans from September 23, 2005, to December 31, 2017, with gaps, and includes measurements at depths of 9, 19, 29, 40, and 49 meters. Data were collected in situ by NOAA NCEI and are provided in NetCDF format.
Relative differential cross sections for top quark pair production in proton-proton collisions at a center-of-mass energy of 7 TeV. The data comprises 2.05 inverse femtobarns recorded by the ATLAS detector at the Large Hadron Collider between March and August 2011. Measurements are derived as a function of the invariant mass, transverse momentum, and rapidity of the top quark pair system, with events selected in the lepton-plus-jets channel.
NOAA_NCEI provides water temperature and derived turbulence quantities measured by chipod thermistor chains on a PIRATA mooring at 0N,10W in the Tropical Atlantic. The dataset spans from September 23, 2005, to December 31, 2017, with measurements taken at six specific depths. Data are stored in NetCDF format.
The SP-2 experiment on the Vega spacecraft studied the spatial and mass distributions of dust particles in a cometary coma. It covers a mass range from 1.e-16 to 1.e-6 grams using impact plasma and acoustic sensors. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
HLE-Verified is a refined benchmark containing between 1,000 and 10,000 high-difficulty reasoning items across scientific and technical domains. Released by skylenage in early 2026, this version provides a systematic revision of the original Humanity’s Last Exam (HLE) to address community-reported reliability issues.
UHI Cover Dataset is a collection for analyzing the urban heat island effect. It uses land cover and thermal data from the Sentinel-2 satellite mission. The author, organization, and specific data volume are unknown.
DOHMH Health Map - Hepatitis is a directory of verified facilities in New York City providing prevention, testing, and treatment services for hepatitis B and C. The list is compiled and updated annually by the NYC Department of Health and Mental Hygiene's Viral Hepatitis Program, in collaboration with state-contracted and network agencies. Each record represents a service offered at a single location, organized by service type.
A Web Feature Service (WFS) provides the development plan 'Bühl; Amendment' for the municipality of Untermünkheim, based on the XPlanung 5.0 standard. The plan amendment entered into force on August 13, 1977, and concerns only part of the original text. The service is published by the Bundesamt für Kartographie und Geodäsie.
7274 rock samples from Japan have their physical properties recorded in a standardized database. The dataset, created by SCIOPS and last updated in March 1988, includes nine key properties such as density, porosity, thermal conductivity, magnetic susceptibility, and P-wave velocity. It is intended to provide basic data for geophysical prospecting.
Optical readings likely intended for the detection of hemoglobin levels. The dataset is hosted on Kaggle, but its exact size, origin, and creation date are unspecified. Columns, sample data, and detailed metadata are unavailable.
NASA's LANL 1989-046 Magnetospheric Plasma Analyzer (MPA) data provides ion and electron density, velocity, and temperature measurements. The dataset includes parameters in multiple coordinate systems, such as GEI and spacecraft coordinates, at approximately 87-second intervals. It was last updated on the platform in March 2026.
569 breast mass biopsy records to classify malignant or benign tumors. The data includes 32 nuclear features derived from cell nuclei measurements. The original author, organization, and collection time range are unknown.
Replication data for a study on high-resolution thermal conductivity measurements in the cuprate material La2CuO4. The dataset was authored by Jiayi Hu and is hosted on the Harvard Dataverse platform. It was last updated on April 13, 2026.
Four new studies challenge a seminal 2004 cross-cultural experiment on semantic intuitions. The data likely contains survey responses from Western and East Asian participants regarding Kripke's Gödel example. This dataset, associated with a paper by Justin Sytsma, is sourced from the paperswithcode platform.
Hans‐Jürgen Hinz authored a paper describing the measurement and analysis of biological substances using Differential Scanning Calorimetry (DSC). The description details procedures for DSC measurement, calibration, and performance testing, including an inter-laboratory study on hen egg white lysozyme. The dataset likely contains thermodynamic transition data, such as temperature and enthalpy values, for proteins, nucleic acids, and lipid assemblies.
John Lofland's book provides a sociological study of the American peace movement during the 1980s. The analysis blends the author's personal involvement with professional assessment to explore the movement's organization, culture, and tactics. It compares the movement's surge and decline to other social movements, particularly those practicing civil protest.
A book by David E. Thaler offering a framework to understand Iranian leadership dynamics. The research provides a primer on the structure, institutions, and personalities of the Iranian government and influential power centers. It aims to help U.S. policy makers and analysts understand the strategic culture underlying Iranian policy formulation.
