- A new view of Xe and Ne in the Paleoarchean atmosphere from paired noble gas isotopic and trace element analyses of Barberton chertsHere, we include the main text and supplementary data tables associated with the manuscript "A new view of Xe and Ne in the Paleoarchean atmosphere from paired noble gas isotopic and trace element analyses of Barberton cherts," submitted to GCA. In this paper, we present high precision noble gas abundances and isotopic ratios paired with ion images for select trace elements from four cherts of the 3.26-3.55 Ga Onverwacht Group in Barberton, South Africa. These data demonstrate that cherts are capable of trapping ancient gases with compositions comparable to previous studies of hydrothermal quartz or barites (e.g., Avice et al., 2018, GCA), and provides critical new insight: the trapped ancient compositions of all samples have been variably overprinted by modern atmospheric gas, and estimates of the extent of past mass-fractionation are truly lower limits. Using a multi-component mixing model, we show that the ~3.3 Ga atmosphere was characterized by a Xe composition fractionated by a minimum of 19 ‰/amu relative to the modern atmospheric composition, nearly twice as strongly fractionated as the most recent estimate (Broadley et al., 2022; GCA). Our data indicate very limited contributions of Xe produced after emplacement by Ba, Te, and U. Our study cautions that both hydrothermal quartz and chert are susceptible to post-depositional alteration that must be understood in order to accurately characterize how the terrestrial atmospheric Xe isotope composition changed over Earth history, mostly likely due to atmospheric loss to space. In addition, Onverwacht chert Ne isotopic data suggest a sub-atmospheric Paleoarchean 20Ne/22Ne composition (< 9.7). SIMS data were gathered using the Cameca 7f-geo at Washington University in St. Louis. Noble gas data were collected using the Nu Noblesse HR 5F5M at Washington University in St. Louis.

- Carbon-Market Fragmentation after BrexitAfter Brexit, UK and EU carbon prices diverged, with a UK discount of about €23/tCO₂ emerging in 2023, creating a natural experiment in carbon-market fragmentation. We examine whether this gap redirected CPC Y02 green-technology patenting in CBAM-exposed sectors: steel, cement, aluminium, fertiliser, and hydrogen. Across seven specifications, the estimated effects are consistently Porter-compatible and economically meaningful. However, none remains significant under randomization inference that properly accounts for a single treated country. The most defensible interpretation is a forward-looking response to expected policy developments—such as a future UK CBAM or potential EU–UK ETS relinking—rather than confirmed evidence of a UK-specific causal effect. More broadly, the findings highlight a key lesson for Brexit and other single-jurisdiction studies: firm-level disaggregation can improve precision, but it does not create additional treated clusters; credible inference remains constrained by country-level permutation tests.

- Registered adolescent homicide mortality in Colombia, 2015–2024: data and reproducibility packageThis repository contains the processed analytic data, R scripts, model outputs, diagnostics, tables, and figure source files used for the study “Registered adolescent homicide mortality in Colombia, 2015–2024: Bayesian spatiotemporal mapping of geographic inequality.” The study analyzed registered homicide deaths among adolescents aged 10–19 years in Colombia during 2015–2024 using Bayesian areal disease-mapping models with BYM2 spatial effects, temporal random-walk priors, and space–time interaction structures. The repository includes aggregated department-year data, population denominators, department-level Multidimensional Poverty Index covariates, spatial adjacency files, posterior annual and department-level mortality estimates, exceedance probabilities, hotspot-persistence summaries, residual spatial risk estimates, model diagnostics, sensitivity analyses, and source files for the main and supplementary figures. Raw restricted administrative or medico-legal microdata are not redistributed; the files provided are intended to support transparency and reproducibility of the reported tables, figures, and analytic workflow.
- Fine-Tuned Small LLMsWe report what is, to our knowledge, the largest properly powered expert human evaluation of this task to date — four experienced curriculum specialists, a fully crossed design spanning five open-source model families, three school-age bands, and three weighted educational dimensions — triangulated against two automatic protocols. The dual-rubric result, in particular, is a methodological contribution to how our field evaluates AI-generated educational materials.
- Utilizing Plethodontid Occupancy to Assess Initial Ecosystem Responses to Invasive Plant Control Treatment in Central HardwoodsThis data reflects occupancy sampling of Plethodontid salamanders in West Virginia, USA across lands treated for invasive plant control. We hypothesized negative impacts on odds of salamander occupancy on treated sites due to loss of vegetative structure and increased predation risk. Our data identified decreased occupancy odds on treated sites, decreased occupancy odds on sites with lower canopy cover, and high interspecific variation in occupancy. Our results reflect potential indirect damage to Plethodontids and correlated ecosystem services from invasive plant control efforts. We collected vegetation and salamander data across 60 sites in West Virginia, USA, across 12 sampling occasions. Vegetation sampling was completed once and included vegetation data in 0.02 ha plot. Salamander sampling took place within the same plot, and included the use of visual and coverboard sampling, completed 12 times at each site. We also measured observation level variates, such as soil temperature at the time of sampling. We used a single-season, single-species occupancy model to test hypotheses, using the "unmarked" package in RStudio. To include multiple species, we coded each species as a factor with its own occupancy intercept. Additionally, to address a potential closure assumption violation, we coded Season as a covariate to observe occupancy odd differences between 'Spring' and 'Fall' sampling. The 'Treatment' covariate in our modeling is a binary covariate, meaning sites were simply treated for invasive species (1), or did not receive treatment (0). Therefore, while we see a decrease in occupancy odds between treated and untreated sites, we do not know what is driving this difference. Herbicide impacts, loss of vegetative structure, increased predation risk, or a combination of these could all be driving a larger 'Treatment' effect.

- Dataset for noncentral collisions of two-dimensional logarithmic quantum droplets: momentum-controlled transition from capture to scattering.This dataset contains the diagnostic time series, summary tables, and figures supporting the manuscript “Noncentral collisions of two-dimensional logarithmic quantum droplets: momentum-controlled transition from capture to scattering.” The simulations solve a dimensionless logarithmic Gross--Pitaevskii equation using a split-step Fourier method. Base collision scans were performed for (k_0=0.25), (0.50), and (0.75), with impact parameters (b=0.0), (0.5), (1.0), (1.5), and (2.0). The data support a preliminary regime map showing quasi-elastic scattering, delayed separation, and a long-lived captured oscillatory state. A refined validation of the captured state at (k_0=0.25), (b=2.0) is included up to (t=80), using (L=48), (N_x=N_y=512), and (\Delta t=2.5\times10^{-4}).
