Using movement data from satellite telemetry to infer nesting status and breeding propensity of a colonial breeder, the American common eider (Somateria mollissima dresseri)

Abstract Background American common eiders ( Somateria mollissima dresseri ) are ecologically and culturally important sea ducks in northeastern North America. Female eiders may not breed every year, making breeding propensity (the proportion of sexually mature females breeding i...

Local Trade‐Offs Shape Flower Size Evolution Across Arabidopsis thaliana Distribution

The remarkable variation in floral form and size is thought to have driven the evolutionary radiation of angiosperms and has traditionally been attributed to pollinator-mediated selection on floral displays, yet emerging evidence indicates that abiotic environmental factors can a...

Using Tower‐Based Observational Networks to Assess the Impact of COVID‐19 Lockdowns on Greenhouse Gas Emissions in Six North American Cities

Abstract The onset of the COVID‐19 pandemic in North America and the lockdowns that followed in March 2020 brought forth a rapid change to societal functions disrupting many aspects of normal life, including the greenhouse gas emissions associated with them. In this work, we exam...

Temporal Data Structure Is Not Causal Identification: A Practical Framework for Appraising Causal Claims in Prevention and Population Health Research

Abstract Temporal data structure is not an identification strategy. In manuscript review and reporting, cross-sectional and longitudinal labels are sometimes used as shorthand for judging whether causal claims are appropriate. Whether a causal claim is credible depends on the eff...

Does crowdfunding democratise funding access for female entrepreneurs in the video game industry?

Focusing on reward-based crowdfunding, this study examines whether gaming entrepreneurs’ gender influences their crowdfunding success and illuminates the gatekeeping role of a crowdfunding platform in relation to gender equality in crowdfunding for video games. By analysing the d...

Understanding consumer reactions and corporate reputation in corporate sustainability crises: The role of blame, harm, and CSR relevance

This study investigates how consumers' behavioral responses vary across different types of corporate sustainability crises characterized by differences in potential harm, attribution of blame, and relevance to Corporate Social Responsibility (CSR). We also examine the moderating...

Flame Transfer Function Measurements In A Multi-Element Combustor With Blends of Natural Gas And Hydrogen

Abstract Hydrogen is a key pathway for gas turbine decarbonization and optionality in sectors where energy demand is rising rapidly. Several demonstrations have shown that hydrogen blending is successful in currently operating gas turbines. However, due to significant differences...

Towards A Universal Analytical Model of Population III Star Formation: A Bridge Between Cosmological Scales and Protostars

Abstract We construct an analytical model of Population III star formation that connects the cosmological radiation background to sub-AU protostellar disk fragmentation, a dynamic range inaccessible to any single simulation. Our approach is based on combining separate models of t...

Unveiling non-Hermitian band structures with non-Bloch supercells

Abstract Real-valued band structures underpin the analysis of periodic Hermitian systems and are well established experimentally. By contrast, non-Hermitian systems feature complex band structures, in which energy and momentum acquire imaginary parts, enabling phenomena that defy...

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

Abstract Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping their spatial structures are therefore crucial for understanding how large-scale environme...

Touching Grass in the Age of AI: Hyperreality and What is at Stake for Leisure?

Building on Baudrillard’s theory of hyperreality, we introduce the concept of “AI-mediated Hyperreal Leisure” (AI-HL), a form of leisure that is not only generated but also continuously reshaped by AI systems, until simulations predominantly define the very notion of leisure. AI-...

The influence of El Niño-Southern Oscillation on cool-season precipitation variability in the arid Middle East

Abstract. Interannual variability in precipitation across the Middle East is of high societal and environmental relevance given the region's arid climate and limited water resources. While previous studies have linked the El Niño-Southern Oscillation (ENSO) to interannual precipi...

“Education in my Hands”: Community Embedded Computing Education in a Youth Boxing Gym

Broadening the participation of Black youth in computer science (CS) is often focused on traditional classroom settings. However, formal school settings can be antagonistic to racially marginalized youth, which may diminish their enthusiasm for CS. We propose community embedded c...

Methods for analyzing acetylcholine-induced vasodilation in human skin

Intradermal microdialysis, combined with laser‑Doppler flowmetry and local heating, is commonly used to investigate mechanisms of endothelial function and dysfunction in the cutaneous microcirculation. Local perfusion of acetylcholine (ACh), with and without N G ‑nitro‑L‑arginine...

Economic insecurity, technology, and violence: how socioeconomic status moderates support for political violence

This study examines how fear of economic insecurity and technology-related fear shape support for political violence in the U.S., with particular attention to the moderating role of socioeconomic status (SES). Drawing on nationally representative data from the 2024 Chapman Univer...

Standardizing assessment of novel methods for ecological data collection

Abstract Methodological advances in ecology enable more efficient data collection, yet researchers need to clearly and consistently report the ways in which these methods benefit their own research within the context of their specific needs. Here, we advocate for greater standard...

ResidualPlanner+: a scalable matrix mechanism for marginals and beyond.

Abstract Noisy marginals are a common form of confidentiality protecting data release and are useful for many downstream tasks such as contingency table analysis, construction of Bayesian networks, and even synthetic data generation. Matrix mechanisms, an important class of priva...

Are client ties pre‐entry resources? Performance implications of client tie diversification

Abstract Research Summary This study investigates client tie diversification, where firms enter markets with existing clients. Recognizing the theoretical basis for both positive and negative performance implications, the paper adopts a question‐driven approach and discovers a st...

Seismic Performance and Design of Concrete-Filled Double-Steel-Plate Composite Coupled Shear Wall with U-Shaped Steel–Concrete Composite Beams

Abstract Concrete-filled double-steel-plate composite shear walls and cold-formed U-shaped steel–concrete composite beams have been recently developed for high-efficiency steel plate–concrete composite structures. In this study, a novel composite coupled shear wall (U-DSP-CW) spe...

Neanderthal’s heel: How the Neanderthal’s external calcaneal shape uniquely differs from that of modern humans

Neanderthals exhibit unique morphological adaptations in their calcaneus compared to Homo sapiens , shedding light on distinct evolutionary pressures and functional requirements shaping their respective foot anatomy. This study assesses which calcaneal traits represent plesiomorp...
