San Francisco's dataset contains resolutions adopted by the Board of Supervisors and Mayor granting waivers to exceptions in the Campaign and Governmental Conduct Code for behested payments. The dataset is manually updated when a new waiver resolution is passed. It is published by the City of San Francisco and includes waivers for payments under $1,000 and solicitations under specific city programs.
111 seabed sediment samples were collected in May 2013 during the SOL5754/GA0340 marine survey of the Leveque Shelf, Browse Basin. Geoscience Australia, in collaboration with the Australian Institute of Marine Science, conducted this survey to assess the CO2 storage potential of the region. The dataset includes grain size analysis results measured by laser diffractometer.
Oceanographic measurements collected near Spain and Portugal under the Advanced Optical Properties Experiment (AOPEX) program. The dataset is provided by the National Aeronautics and Space Administration (NASA) and was last updated in March 2026. It contains data on ocean optical and chemical properties.
The Nuclear Decision-Making Benchmark is one of the first benchmarks for large language models covering nuclear escalation, non-proliferation, proliferation, and arms control domains. Developed with subject-matter experts in international relations, it presents geopolitical scenarios as multiple-choice questions with exchangeable country pairs and phrasings. The benchmark includes evaluation results from seven state-of-the-art large language models.
March 2026 data from the Canadian Space Agency describes Laser-Induced Breakdown Spectroscopy (LIBS), an emerging analytical technique for material composition. It enables stand-off, real-time analysis with no sample preparation. The dataset supports planetary materials analysis.
1994 and 1996 growing seasons of spectral optical property measurements for boreal forest tree leaves. The BOREAS TE-10 team collected reflectance and transmittance data using a Spectron Engineering SE590 spectroradiometer at seven SSA sites. This dataset supports the characterization of vegetation biophysical properties for the Boreal Ecosystem-Atmosphere Study.
DC electric field measurements sampled at 16 samples/s from the Dynamics Explorer 2 satellite's Vector Electric Field Instrument (VEFI). The instrument used 20-m baseline double-probe techniques to measure fields with a planned range of ±1 V/m and resolution of 0.1 mV/m. The dataset was produced by NASA and includes variational electric field measurements from 4 Hz to 1024 Hz.
From August 15, 1981 to February 16, 1983, this dataset provides daily files of merged high-resolution magnetic and electric field measurements from the Dynamics Explorer 2 satellite. It was created by NASA by combining data from the Vector Electric Field Instrument (VEFI) and Magnetometer-B (MAGB) systems, with added orbit-altitude parameters like satellite altitude and geographic coordinates. The dataset includes fill values for periods where one instrument's data was unavailable, and the total number of records varies per day.
Mid-Atlantic Ridge data comprises 3D wide-angle seismic recordings from 18 ocean bottom nodes collected during the RRS James Cook cruise JC254 in November 2023. The data were acquired at the 13°30'N Oceanic Core Complex and Semenov Hydrothermal Field, shot in six sequences along 15 profiles using GI-guns. This raw SEGY dataset aims to derive a seismic velocity structure to investigate crustal lithologies and the interplay of tectonic faulting, magmatism, and hydrothermal circulation.
NASA's CAMEL dataset provides monthly emissivity uncertainty estimates at 0.05 degree resolution globally. The CAM5K30UC product includes three independent components of variability: temporal, spatial, and algorithm uncertainty, calculated for 13 spectral hinge points. Version 2 incorporates additional laboratory datasets to improve characterization of snowy scenes.
Geoscience Australia Data published a report on a radioactive find in the Mt Johnstone area of the Strangways Range, Northern Territory. The dataset, last updated on 2026-05-06, is available in PDF and HTML formats. Legacy product metadata is minimal, with no abstract or column details provided.
Boreal Ecosystem-Atmosphere Study (BOREAS) TE-12 team data contains hemispherical spectral reflectance and transmittance measurements for individual boreal vegetation components. Measurements cover leaves, needles from three growth years, twigs, and substrate, collected at four SSA sites in 1993 and 1994 using a LI-COR LI-1800-12 integrating sphere and Spectron Engineering SE590 spectroradiometer. The dataset supports research into the optical properties of northern forest vegetation.
Victim records from Colombia's Unit for the Comprehensive Care and Reparation of Victims (UARIV), updated monthly. The dataset tracks individuals affected by conflict-related events, categorized by demographics like ethnicity, sex, life cycle, and disability status. Data is published via the national open data portal.
262,144 grid cells represent a 2D pathfinding problem with 30% obstacle density and a random speed field. The dataset was created by Francisco Angulo de Lafuente to benchmark GPU-accelerated navigation algorithms, specifically the Optical Neuromorphic Eikonal Solver. The solver achieves a 135x average speedup over CPU Dijkstra with sub-1% accuracy.
NASA Visible Infrared Imaging Radiometer Suite (VIIRS) calibrated radiance data from the JPSS-2/NOAA-21 satellite. The product comprises sixteen moderate-resolution bands with a spatial resolution of 750 meters at nadir, including eleven reflective solar bands and five thermal emissive bands. Data includes calibrated radiance and reflectance, quality flags, and metadata, with reprocessing updates for the reflective solar bands.
Rongyu Ping's research provides a multivariate Cox regression model for predicting postoperative recurrence of intrahepatic cholangiocarcinoma (iCCA). The model is based on proteomic data from 116 iCCA adjacent-to-tumor tissue (ATT) samples and validated on an independent cohort of 88 samples. It identifies four key molecular features (ENO3, HSPA13, POSTN, PTBP3) and stratifies patients into high-risk and low-risk recurrence subtypes.
A proteomic analysis of 116 adjacent-to-tumor tissue samples from intrahepatic cholangiocarcinoma patients, used to construct a postoperative recurrence prediction model. The study identified two molecular subtypes and a four-molecule signature (ENO3, HSPA13, POSTN, PTBP3) for risk stratification, with validation performed on an independent cohort of 88 samples.
Polygons depicting Geothermal allocations from the Greater Sage-Grouse Approved RMP Amendment (ARMPA) in Montana and the Dakotas. The data reflect decisions made in the ARMPA and associated Record of Decision (ROD), carrying forward stipulations from earlier Resource Management Plans. The dataset is provided by the Department of the Interior and was last updated on March 12, 2026.
A compact electrostatic Ultrafast Electron Diffraction instrument operates at a cathode voltage of 100 kV, producing ~200 fs electron pulses.
