Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Abstract Top‐down studies of methane (CH 4 ) emissions often use the average ethane‐to‐methane (C 2 /C 1 ) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH 4 sources (ruminants, wetlands, landfills, and other methanogenic sou...

Estimation of Property Value Changes from Nearby Carbon Capture, Utilization, and Storage Projects in the United States

Abstract Carbon capture, utilization, and storage (CCUS) is vital to decarbonization, but its socioeconomic impact on nearby communities remains understudied. Using property-level housing transaction data (1990–2021) matched to nationwide CCUS project records, we apply a hedonic...

Dissociable neural correlates of tonic and phasic irritability during reward processing in young children

Background Irritability is a common and impairing feature of childhood psychopathology and is increasingly conceptualized as comprising tonic (persistent irritable mood) and phasic (reactive temper outbursts) components. Although these dimensions show partially distinct behaviora...

The Paradox of Unhappy Economic Growth: Is the U.S. An Outlier?

Typically, income is positively related to happiness and other well-being measures, even with diminishing returns. The relationship is weaker, but positive, when comparing within-country income changes with wellbeing changes. Yet new evidence suggests that most subjective well-be...

Pre-fire forest type as an integrated indicator of long-term post-fire aboveground biomass recovery in boreal forests

As the largest terrestrial biome, boreal forests play a critical role in the global carbon cycle, support diverse wildlife habitats, and sustain timber production, while wildfires represent a major natural disturbance shaping their function. Understanding post-fire aboveground bi...

Segmentation gene expression and function in Vanessa cardui, an emerging model for Lepidoptera

Although all insects are segmented, the genes that control this process vary across species. Many of the pair-rule (PR) genes that direct segment formation in Drosophila are similarly utilized in other holometabolous insects, but more distantly related species use different genes...

The genomic origins and evolutionary path to a key innovation in the world’s most venomous snakes

Abstract Evolutionary innovation is a key driver of the colonization of new environments and the adaptive radiations of major groups. Novel traits typically evolve through the modification of pre-existing characters but the genetic paths underlying their origin have been challeng...

Toward Pristine Return: Probabilistic Sample Response Modeling of Vibration Sensing for Planetary Samples

Planetary sample return missions can impose extreme mechanical forces on both spacecraft and the returned samples collected from a planetary surface that they contain. The chain of custody phases from entry/descent/landing to curation each present distinct vibration, shock, and d...

Image-aware mixture of experts automates the detection of ovarian follicle rupture in a high-throughput ex vivo ovulation assay

An AI-based dynamic, image-aware Mixture-of-Experts (MoE) framework automates ex vivo ovulation detection and offers a highly accurate, scalable solution for studying the biology of ovulation, drug development, and reproductive toxicity testing.

Modeling justice without deciding it

Integrated assessment models shape climate policy by estimating mitigation costs and tracing pathways with different consequences across countries, income groups, and generations. As equity and justice become more prominent in this work, a basic question follows: what gives a mod...

Care Models for the Genetic Evaluation of Dilated Cardiomyopathy at Sites of the DCM Consortium

Abstract Background Clinical genetic evaluation for patients with dilated cardiomyopathy (DCM) is minimally implemented and models of care are not defined. To understand current genetics care for DCM, a systematic needs assessment was conducted. Methods Principal Investigators (P...

A cross-instrument closure and polarimetric study for improving sub-millimeter polarimeter-radiometer ice cloud microphysics retrievals

Abstract. Ice cloud microphysical properties, such as phase, shape, size and density, introduce significant uncertainties and biases that affect our understanding of how clouds influence weather and climate. The upcoming spaceborne sub-millimeter radiometers are expected to help...

A High-Resolution Stereo-Seq Spatial Transcriptomic Resource for Adult Holstein Cattle Liver

The bovine liver is a highly compartmentalized organ that plays essential roles in continuous gluconeogenesis and nitrogen recycling; however, its spatial molecular architecture has remained largely uncharacterized due to the limitations of traditional bulk and single-cell approa...

Retrieval Augmented Generation for Relative Distance-based Spatial Reasoning

Large Language Models (LLMs) can be applied to various real-world tasks, many of which require spatial reasoning, like pattern-based spatial search, Point of Interest (POI) recommendation, and itinerary or travel planning. However, on their own LLMs have been shown to lack reliab...

A data-driven channel infilling rate forecasting framework with quantified uncertainty for Southwest Pass and Houston Ship Channel

Dredging operations in navigational waterways are essential to maintain channel depth to ensure the safe passage of vessels. Existing shoaling forecasting tools often rely on heuristics or direct modeling of cumulative sedimentation, limiting lead time and predictive reliability....

Starve-Feed Cycles Direct Quiescence to Proliferation Transitions in Drosophila Follicle Stem Cells via Transcriptional Regulation

Stem cell quiescence is a reversible state in which cells temporarily exit the cell cycle but remain poised to re-enter, on cue. Robust protection of the balance between stem cell quiescence and proliferation (Q->P) is critical for long-term tissue health. Proliferation without p...

Evaluation of Pandora HCHO and NO 2 with airborne in situ observations

Abstract. The Pandora Global Network (PGN) is a system of ground-based spectrometers reporting continuous daytime column HCHO and NO2. While the Direct Sun (DS) NO2 product has been well studied, the Multi Axis Differential Optical Absorption Spectroscopy (MAX DOAS) products are...

Cultural Fit, Privacy Concerns, and GCC Women’s Openness to AI-Enabled Menstrual Tracking: A Cross-Sectional Study

Artificial intelligence (AI) is increasingly embedded in menstrual and reproductive health applications, yet little is known about how women in conservative, rapidly digitizing regions evaluate AI-enabled menstrual tracking tools. This study investigates how perceived cultural fi...

Do I Even Need a Multilevel Model? Negligible Effect Significance Testing for Intraclass Correlation Coefficients

In applied research, the decision to utilize multilevel modeling (MLM) is commonly guided by comparing a point estimate of the unconditional intraclass correlation coefficient (ICC) against some recommended threshold (e.g., 0.05). This naïve approach, however, fails to account fo...
