Branching Out: How Constitutional Isomerism Influences Volatility in Butyl Acetates

This project investigates how molecular branching affects the evaporation rate (volatility) of butyl acetate isomers used in fragrances. By analysing published chemical data, I compared linear and branched structures. The results proved that increased branching lowers boiling poi...

A comparative “report card” wellbeing assessment of 22 countries in the Global Flourishing Study

When evaluating how countries are faring, there is a widespread tendency to rely on single metrics or indices, whether objective (e.g., GDP) or subjective (e.g., life evaluation). However, flourishing is multidimensional, and societies invariably do better in some ways and less s...

Gender roles and identity at Chiribaya Alta, Peru: A multiple correspondence analysis of mortuary contexts

Gender is an important structuring social identity, but archaeologists continue to struggle with non-binary ways to approach gender in the past. This study uses grave good presence and absence to examine the nature of gender roles and gender identity at Chiribaya Alta, Peru. Mult...

A Wastewater-basedModeling Framework for InferringNorovirus Transmission Dynamics

Abstract Norovirus is a leading cause of gastroenteritis globally, yet its true infection burden in the community remains poorly understood because of widespread asymptomatic transmission and underreporting. Wastewater-based surveillance is a promising approach for tracking infec...

Provider-Identified strategies to address homelessness in Arizona: a summary of strategies, evidence, and impact

Few sources have reviewed the state of the evidence on commonly implemented and emerging strategies to prevent and respond to homelessness in the United States. We conducted focus groups with 58 homeless service providers and administrators across Arizona about strategies used to...

VIA1 is a conserved regulator of thylakoid membrane integrity that acts through VIPP1

Abstract Thylakoid membranes are indispensable for oxygenic photosynthesis, yet the mechanisms that protect these membranes from photooxidative damage remain poorly understood. By screening previously uncharacterized proteins induced during the chloroplast unfolded protein respon...

Dual Burden of Community Violence and Policing in A Large Urban City

Abstract Marginalized urban communities are affected by both high levels of violence and pervasive police presence. This qualitative study examined the dual burden of violence and over-policing, which contributes to hypervigilance and stress among community members. To explore th...

Spanish–Guaraní Code-Switching in Social Media: A Dependency Parsing Study

Aims and Objectives/Purpose/Research Questions: This study examines how Spanish–Guaraní bilinguals structure code-switching (CS) on Twitter/X and investigates what these patterns reveal about competing models of bilingual grammar. Specifically, it explores language dominance, swi...

High symmetry embeddings of rectilinear tangles

Abstract Finite tangles are embeddings of graphs that include knots or links as subcomponents. We describe vertex-transitive tangles with 12 or fewer crossings, as well as tangles with just two crossings that feature the Hopf link. Additionally, we consider tangles formed by addi...

Electron Shot Noise on a Current Biased Antenna

Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative...

Homicide at home: setting the agenda for an international collaboration to improve support for children bereaved due to family violence

Background: Bereavement due to fatal family violence (e.g. intimate partner homicide, filicide, parricide, siblicide) is a profoundly disruptive experience for children, with lifelong psychosocial consequences. Although the need for fatal family violence prevention is increasingl...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Older Adults’ End-of-Life Care: Are Retrospective Assessments Patterned by Proxy Relationship to Decedent?

BACKGROUND AND OBJECTIVES: Understanding the quality of older adults' end-of-life care is essential for informed decision-making and practitioner accountability. However, retrospective appraisals provided by proxies may be shaped by their relationship to the decedent. Failure to...

Computer-Vision-Enabled Worker Video Analysis for Motion Amount Quantification

The performance of physical workers is significantly influenced by the extent and quality of their motions. However, accurately measuring and assessing these motions remains a challenge due to the limitations in conventional instrumentation; wearable sensors require calibration a...

Skuas as sentinels of high pathogenicity avian influenza H5N1 on the Antarctic Peninsula in the 2024/2025 austral summer

Despite Antarctica's geographic isolation, the first incursion of high pathogenicity avian influenza (HPAI) H5N1 was detected in the 2023/2024 austral summer. Surveillance for HPAI H5N1 in Antarctica remains patchy due to logistical, financial and infrastructure challenges, with...

Varietal development and rice yield growth in India: assessing IRRI’s germplasm contribution

This study analyzed the contribution of International Rice Research Institute (IRRI) improved germplasm to rice varietal development and yield growth in India. Out of the total of 1436 released high-yielding varieties (HYVs) of rice, 769 (53%) were developed using IRRI improved g...

ReDON: Recurrent Diffractive Optical Neural Processor with Reconfigurable Self-Modulated Nonlinearity

Diffractive optical neural networks (DONNs) have demonstrated unparalleled energy efficiency and parallelism by processing information directly in the optical domain. However, their computational expressivity is constrained by static, passive diffractive phase masks that lack eff...

The Role of Meso-level Organizations in Climate Adaptation for Small-Scale Producers in Sub-Saharan Africa-insights from four African Countries

<title>Abstract</title> This analysis examines the meso-level organizations (MLOs) that are core climate change adaptation (CCA) actors responsible for interweaving micro-level rural community needs with macro-level policy and finance intentions, using qualitative data from four...

Risk Stratification of Patients Being Considered for Open Abdominal Aortic Aneurysm Repair

Background/Objectives: Endovascular repair (EVAR) is the default for most abdominal aortic aneurysms (AAAs), yet open repair (OR) remains necessary, and the decision hinges on fitness for open surgery. No standardized preoperative tool defines who is “unfit” for OR. We derived an...

Prekindergarten and Kindergarten Predictors of Reading Comprehension in Monolingual English and Spanish-English Bilingual Sixth Graders.

PURPOSE: Poor reading comprehension performance by children in the United States is a continuing concern. Early identification and intervention can reduce the number of children with significant reading problems. We documented prekindergarten and kindergarten predictors of Grade...
