Harvard University Press provides R code and data for simulating community phylogenies and calculating phylogenetic diversity metrics. The resources support statistical analyses comparing simulated and empirical data, likely using linear mixed-effects models. This work appears in the fields of ecology and evolutionary biology, focusing on the impact of taxon sampling on phylogenetic inference.
Experimental data from a study investigating the effect of filler size and loading on the wear of flowable resin composites. The dataset likely contains volumetric wear loss measurements for nine composite formulations, tested across 40,000 cycles using a cyclic loading device. The research was authored by Koichi Shinkai and published via the paperswithcode platform.
Experimental data from an 'observe or bet' task comparing human behavior in changing versus unchanging environments. The dataset likely contains trial-level records from a behavioral experiment conducted by Danielle Navarro at The University of Texas at Austin. A Bayesian analysis of the task is presented, with findings suggesting human judgments align with a model assuming a higher-than-actual rate of environmental change.
A paper by Clarence E. Rash discusses human factors in helmet-mounted displays for military applications. The abstract focuses on the integration of human sensation, perception, and cognition with advanced display systems. The dataset likely contains the full text of this research paper.
A 233.4 KB dataset authored by Belmiro P.M. Duarte and last updated on 2026-06-02. It supports a framework for maximum von Neumann entropy optimal experimental design, leveraging semidefinite programming for multiresponse models with correlated outputs. The dataset includes Python code and a PDF document illustrating applications in dose-response, sensor placement, and kinetic modeling.
Experimental data from a study proposing a dynamic principal component analysis methodology for detecting progressive failures in spur gearboxes. The dataset covers combinations of load, speed, and failure severity, validated using vibration signals segmented and characterized with time and frequency domain indicators. It was authored by Antonio Pérez-Torres and last updated on 2026-05-18.
Comments and documentation regarding credit changes and deviations from budget estimates for the city of Linz for the year 2018. The data was published via the Cooperation OGD Österreich and Wikimedia Österreich initiative. It includes information on credit transfers, credit overruns, and budgetary balances.
Statistical information on the solar potential cadastre for Vienna, Austria. The data is provided by Cooperation OGD Österreich and Wikimedia Österreich under a CC-BY-4.0 license. The dataset is available in CSV format.
June 2015 statistical information on changes in the registration of Public-Private Partnerships (PPPs) and registered vehicles by type and area. The data includes summary information on the number of vehicles initially registered and recorded. It was provided by the Data Department of the State e-Government Agency.
Canadian international assistance data is published annually by Global Affairs Canada, as mandated by the Official Development Assistance Accountability Act. The report provides a detailed account of assistance provided each fiscal year, published one year after the period ends. It originates from the open_canada platform under the OGL-CA-2.0 license.
Q-mode factor analysis classified estuarine sediment samples from Broad Sound, Queensland, into two geologically distinct groups representing intertidal and supratidal deposition. The dataset, hosted by the Australian Ocean Data Network, was last updated in June 2026. It identifies processes controlling concentrations of P2O5, Cu, Pb, and Zn using R-mode factor analysis and stepwise regression.
Lin Han authored a study investigating anti-Kelch-like protein 11 (KLHL11) encephalitis, published on figshare. The work includes detailed reports of two patient cases and a review of literature from the last six years. The dataset comprises a 415.8 KB PDF document.
Two case reports detail the clinical features and treatment responses of patients with anti-Kelch-like protein 11 (KLHL11) antibody-associated encephalitis. The data includes patient ages, antibody titers, treatment regimens, and outcomes. The document was authored by Lin Han and last updated on June 1, 2026.
Aggregated data from a database merging scans of main UK Social Security Benefits. The data is aggregated at the 1992 ward level. This series has been suspended as of 2018 until further notice.
A retrospective pharmacovigilance analysis of 5,860 ocular adverse event reports associated with five SNRIs extracted from the FDA Adverse Event Reporting System (FAERS) database from Q1 2004 to Q4 2024. The study, authored by Zhengtai Sun, used disproportionality analyses to identify drug-specific and sex-specific safety signals.
V. Ananiev from the University of Oslo generated fitted toy Monte Carlo samples for the paper "Gaussian Process-based calculation of look-elsewhere trials factor". The dataset includes HDF5 files containing the samples and a Jupyter notebook used to produce the paper's figures. It is intended to enable reproduction of the paper's results and testing of related hypotheses.
A theoretical dataset formalizing the concept of magic, or non-stabilizerness, in quantum computing. The work provides an exact, decidable, and machine-checked account of the resource a quantum circuit must spend to escape efficient classical simulation. It was authored by Richard Goodman of IAOM and last updated on July 11, 2026.
An experiment embedded the Ellsberg problem in various scenarios to test implicit assumptions under ambiguity. Results showed more participants chose rationally when scenarios suggested a normal probability distribution. The dataset likely contains experimental trial data from this study by Şule Güney of UNSW Sydney.
A theoretical exposition on reframing statistical equilibria as eigenforms of inference operators. The work by Richard Goodman of IAOM, last updated in July 2026, connects concepts across seven fields including relative entropy, exponential families, and optimal transport. The description suggests the dataset likely contains formal definitions, theorems, or illustrative examples supporting this mathematical framework.
A mathematical model for sizing solar photovoltaic water pumping systems was validated in a pilot unit in the rural community of Rio Belo, Orleans/SC, Brazil. The model uses the Generalized Reduced Gradient method, regional solar radiation data, water consumption, well productivity, and pumping system capacity for technical and economic optimization. Validation occurred in a location with an average annual radiation of approximately 4.5 kWh/m².day, showing results close to monitored behavior.
