Transit access disparities in a car-dependent metropolitan context: a socio-spatial analysis of transit deserts in Oklahoma city

Transportation equity emphasizes the fair distribution of transportation resources and access to mobility opportunities, yet disparities in access to public transit remain pronounced in highly automobile-oriented metropolitan areas. This study examines transit access disparities...

Lessons from Three Decades of Maintaining Sand Scorpions in the Laboratory: Husbandry and Survivorship of Paruroctonus utahensis

For over three decades, I have collected and maintained sand scorpions in my research laboratory. I have learned that these animals are not only easy to collect but also accepting of laboratory conditions. In this note, I followed a population of 34 sand scorpions collected from...

Examining Mid-Level Stable Layers Over the Tropical Atlantic during ORCESTRA

Here we investigate elevated stable layers that frequently appeared at an altitude near 6 km in soundings obtained during the ORCESTRA field campaign. This observation deviates from the existing literature, which emphasizes that tropical mid-level stable layers are collocated wit...

Structure-Transport Relationships in Aqueous Fructose Solutions: A Combined Molecular Dynamics and NMR Diffusion Study

Abstract Fructose is widely used in the food industry and is proposed as a sustainable biomass feedstock for chemical manufacturing. Upon dissolution in water, it undergoes mutarotation into different tautomers, primarily β-d-fructopyranose (68%) and β-d-fructofuranose (22%), as...

Co-Adsorption of Novobiocin and Three Common Surfactants on Polystyrene: Molecular Insights from Experiments and Simulations

Abstract In several environments, including wastewater treatment plants (WWTPs), plastics encounter surface-active molecules such as antibiotics and surfactants, essential components of consumer products, detergents, and drugs. In these conditions, synergistic and antagonistic ef...

Development and testing of ensemble-variational data assimilation capabilities for radar data within JEDI coupled with FV3-LAM model

Abstract. This study presents the first implementation and evaluation of radar reflectivity data assimilation capabilities within the ensemble three-dimensional variational (En3DVar) data assimilation (DA) system of the Joint Effort for Data assimilation Integration (JEDI) framew...

The Oil Well as the Mine of the Future: Toward In-Situ Coproduction of Critical Minerals and Hydrocarbons

Abstract The global demand for critical minerals and materials (CMM) is rapidly outpacing conventional supply chains. This Perspective presents a paradigm shift by demonstrating that mature U.S. sedimentary basins are not merely depleting fuel reservoirs but are vast, accessible...

“You’re never going to belong here”: Stigma and acculturation among foreign workers

Foreign (i.e., non-citizen) workers face significant challenges concerning socialization and belonging in the workplace. This research investigates (1) the identity-related challenges of self-initiated expatriate workers and (2) how self-initiated expatriate workers navigate iden...

Seeing the System, Positioning the Self: Engineering Students’ Conceptualizations of Wicked Problems

This qualitative study focuses on how engineering technology students scope and make sense of complex problems. Systems thinking can help engineers address increasing complexity and uncertainty. Social factors including the culture of disengagement and socio/technical dualism hin...

Assessing Emergency Clinicians' Needs From Trauma Clinical Guidance: A Mixed-Methods Study.

BACKGROUND: In the United States, emergency clinicians are often the first to care for injured patients in the hospital setting. Current trauma clinical guidance does not consistently meet the needs of emergency clinicians caring for this population. OBJECTIVES: To better underst...

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe

ABSTRACT Magnetic skyrmions are promising candidates for next‐generation spintronic memory and logic due to their nanoscale size and topological stability. However, skyrmion‐based devices remain limited by narrow operating temperature windows that typically exclude cryogenic regi...

A new method for estimating forest aboveground biomass by integrating sUAV and satellite remote sensing

Aboveground biomass (AGB) is a fundamental indicator for assessing forest ecosystem productivity, biodiversity, and carbon sequestration levels. In AGB remote sensing estimation, traditional methods face challenges such as the limited number of plots and issues with matching plot...

The impact of climate and habitat on body shape and size evolution in charontid whip spiders

Abstract Environmental shifts often dictate Arthropod morphological evolution, yet certain lineages maintain remarkably conserved body plans across diverse habitats. Whip spiders (Amblypygi) emerged over 300 Ma and exhibit striking morphological conservatism; nonetheless, what dr...

Clustering of Right‐Moving Tornadic Supercell Proximity Sounding Profiles Using an Explainable Framework

Abstract This study demonstrates an explainable machine learning framework for explicitly selecting important environmental features that determine clusters of right‐moving tornadic supercells. Although previous studies have clustered and analyzed proximity sounding profiles asso...

Side-to-Side versus Traditional End-to-Side Approach to STA-MCA Bypass in Moyamoya Disease: A Comparative Meta-Analysis

Background Superficial temporal artery to middle cerebral artery (STA-MCA) bypass is a standard-of-care treatment for adult patients with moyamoya disease (MMD). Although the classical technique is end-to-side (E-S) bypass, the side-to-side (S-S) construct has emerged as an alter...

‘Give me a point and I will place the map’: automated georeferencing historical maps using spatially explicit AI

Georeferencing provides a foundation for transforming historical maps into usable data for geographic analysis. Existing methods remain limited in their ability to integrate spatial semantics with geometric feature extraction, accommodate complex street geometries and stay robust...

Ambivalent Multiculturalism in Organizations: The Case of SafeHarbor International

Multiculturalism remains a desirable, yet challenging, dream to realize in the modern workplace. Field research was conducted to investigate multicultural dynamics at a multinational, multilingual organization, headquartered in Japan. This ethnographic case study documents sensem...

Simple supercuspidal representations of $$\textrm{GSp}_4$$ and test vectors

Abstract We consider simple supercuspidal representations of $$\textrm{GSp}_4$$ GSp 4 over a p -adic field and show that they have conductor exponent 5. We study (paramodular) newvectors and minimal vectors in these representations, obtain formulas for their matrix coefficients,...

Effect of AlkaliMetal Ions and Salt Composition onStructural and Dynamical Properties of Ternary Electrolytes

Abstract Molecular dynamics simulations were employed to investigate the influence of alkali-metal ions (Li+, Na+, K+, and Cs+) and salt loading on the solvation structure, coordination environment, and transport properties of ternary electrolytes composed of a short-chain polyet...

Fire-Smoke InducedProtein Alterations in Firefighters'Body Fluids Identify Prognostic Pan-cancer Biomarkers

Abstract Firefighters are routinely exposed to complex mixtures of toxicants during fire suppression, and growing evidence links these exposures to elevated cancer risk. Proteomic profiling provides a sensitive means to detect early molecular alterations associated with such occu...
