title: Data for "Passive acoustic data as phenological distributions: uncovering signals of temporal ecology"

description: Passive Acoustic Monitoring (PAM) is an increasingly common method for monitoring birds and other sound-producing organisms at scale, but methods that digest these data streams into ecological insight remain underdeveloped. Specifically, using PAM and classification algorithms powered by artificial intelligence (AI) to uncover the phenology of vocal animals is an emerging use of these data but currently lacks standardized, repeatable methods with verified connections to biological phenomena. In the paper accompanying this dataset, we articulate specific hypotheses regarding the relationship between avian vocal activity and phenological events, and present a flexible, reproducible methodological workflow for quantifying avian vocal phenology from PAM data. We applied our pipeline to 18,568 hours of audio from 185 recording sites across Olympic National Park, USA.

The data hosted here can be used in concert with the code in the linked Github repository to reproduce the analyses in the manuscript "Passive acoustic data as phenological distributions: uncovering signals of temporal ecology." They should be saved into the "input" folder initialized by the Github repository.

title: <b>Phase-informed design strategy of volcanic ash analogues for jet engine degradation</b>

description: Volcanic ash poses a severe threat to thermal barrier coatings (TBCs) in aero-engine hot sections, causing rapid degradation under high-temperature exposure. However, the compositional variability of natural ash hinders the reproducibility incorrosion testing and the development of standardized evaluation protocols. Here, we systematically evaluated trachyandesite volcanic ash and five synthetic glass analogues with increasing compositional complexity –from quaternary CMAS (CaO-MgO-Al2O3-SiO2) to octonary CMAS-NKTF(additionally containing Na2O, K2O, Fe2O3, and TiO2). Through comprehensive characterization of thermophysical properties up to 1600 °C and TBCs interactions study, we identified that the septenary CMAS-NKT (with Na2O, K2O, and TiO2) analogue achieved 96% overall similarity to vitrified natural ash across multiple metrics including viscosity, thermal expansion, and infiltration depth. This high fidelity stems from its compositional alignment with the Fe-depleted residual melt formed during high-temperature phase separation in natural ash. Our findings establish a phase-informed design strategy for volcanic ash analogues, with CMAS-NKT serving as a standardized material for reproducible TBC degradation assessment.

title: Regulation in vicariously learned fear
title: 观察学习性恐惧调节

description: Given that the adverse effects of observational learning anxiety are more pronounced in the era of self-media, exploring effective emotion regulation methods to intervene in observational learning anxiety is particularly important. Therefore, this study comprehensively employed behavioral and event-related potential (ERP) techniques to induce observational learning anxiety in participants using demonstrator videos. It systematically investigated the intervention effects of interpersonal emotion regulation based on cognitive reappraisal on observational learning anxiety, along with its behavioral and electrophysiological characteristics.Experimental data were collected using E-Prime. Experiment 1 recruited 90 adult participants, all of whom reported no history of psychiatric medication use or mental disorders, were right-handed, and possessed normal vision or corrected vision. Each group comprised 30 participants: the interpersonal regulation group (age 20.47 ± 1.54 years), the self-regulation group (age 20.73 ± 1.24 years), and the no-regulation group (age 20.60 ± 1.20 years). Experiment 2 recruited 48 young participants meeting criteria for physical and mental health without emotional disorders. EEG was recorded using Brain Products equipment. Ultimately, 44 participants yielded valid EEG data: 21 in the self-regulation group (age 20.18 ± 2.01 years) and 23 in the interpersonal regulation group (age 20.13 ± 2.23 years).

Dataset Title



Data inputs for hazards models – Dominica, 2017-2025





Dataset Description



This record presents geospatial datasets (soil, land use, DEM, vegetation parameters, etc.) ready to be used as model input for OpenLISEM and LISEM Hazard or FastFlood. The projection of each file is in UTM20N. 

Some key files are:



dem.map -elevation model, the height of the landscape in meters above sea level.

lai.map - leaf area index, estimated using empirical relationships based on NDVI (Normalized Difference Vegetation Index)). The source data to calculate NDVI is Sentinel-2.

KSat.map - Saturated hydraulic conductivity of the soil, estimated based on a combination of SOILGRIDS soil texture, Saxton et al. (2006) Pedotransfer functions, and a national soil map for Dominica.

clay.map - Clay texture fraction, SoilGrids resampling

silt.map - Silt texture fraction, SoilGrids resampling

sand.map - Sand texture fraction, SoilGrids resampling

cover.map - Vegetation cover as a fraction, estimated using linear correlation with NDVI.

lu_new.map - Spot satellite image classification at 10 meters resolution for predominant land use types.

n.map - Mannings surface roughness coefficient, specific value based on the land use type. 

ndvi.map - Normalized Differential Vegetation Index, based on Sentinel-2 images in summer.

ldd.map - Drainage network map for the island, which can be used for flow accumulation and streamflow detection

catchments.map - Catchment ID's based on the ldd.map drainage network.

Channelldd.map - Channel-only drainage network map, calibrated manually to have all channels on the island represented correctly.

Soildepth - Soil depth in meters, based on a physically-based soil depth model in meters and observational data obtained from landslide-sites during fieldwork in 2018.

Slope.map - Slope map in gradient of the elevation  model (m/m) in the steepest direction






Key Methodologies



Customization of open-source datasets, generation of vegetation parameters and land cover classification.





Temporal Domain



2017-2025





Spatial Domain



Dominica





Key Indicators



Flood, soil, vegetation





Data Format



The raster files are either in Geotiff format or PCraster map format.





Source Data

Multi-source




Accessibility



Zenodo, 10.5281/zenodo.15224885





Stakeholder Relevance



Relevant input for hazard mapping, physically-based modelling, and understanding hazard processes on Dominica





Limitations/Assumptions



Some datasets depend on lower quality/global datasets, and are not specifically calibrated for the island. Others, such as soil depth, infiltration, soil textures, flood extents and vegetation properties, are all in some part verified and tweaked to represent local measurements. See for a methodological description the Msc Thesis work of students at UT-ITC between 2017 and 2025.

title: Higgs Mechanism and Dark Matter from Hexagonal Expander Graph Geometry

description: We demonstrate how both the Higgs mechanism and dark matter emerge naturally from the geometry ofd = 6 Ramanujan graphs in twistor network theory. The model predicts: (1) a Higgs boson mass mH = 125 GeV from determinant fluctuations of the twistor matrix, (2) an axion-like dark matter particle with mass mDM ≈ 10−3 eV as a topological defect, and (3) correct abundance ratios ΩDM/Ωb through graph spectral properties. All parameters derive from the fundamental length scale ℓ = κ 1/2 ≈ 10−18 m

description: The dataset comprises macrocharcoal data (&gt;100 μm) derived from a varved sediment record from Holzmaar, located in the West Eifel Volcanic Field, Germany. The macrocharcoal record was utilized to reconstruct fire occurrence over the past 2,000 years. In addition to this reconstruction, reflectance measurements of charcoal particles were conducted to estimate the temperature of charcoal formation, thereby providing insights into the prevailing fire regimes during specific time periods.
