Developing interactive learning interfaces for teaching AI in health professions education using generative AI tools

Health professions education (HPE) must now equip students to use artificial intelligence (AI) tools safely. We offer an instructional design strategy for HPE educators aiming to teach fundamental AI concepts to non-technical audiences: using generative AI to rapidly create inter...

Impact of a health education intervention on knowledge, attitudes, and use of visibility materials among commercial motorcycle riders: a quasi-experimental study in Cameroon

Abstract Background Commercial motorcycle riders are among the most vulnerable road users in low- and middle-income countries, with poor visibility contributing significantly to road traffic crashes, particularly under low-light conditions. Visibility materials such as reflective...

Framing Displacement, Forcing Perspective: Black Visual Geographies and the Crisis of Homelessness in Oakland

ABSTRACT While Black and visual geographies have examined the image's racial and spatial power, more work is needed to analyze how racial frames of view become spatially embedded. This paper advances such a practice by analyzing news images of homelessness in Oakland. Methodologi...

FullMS2Former:A Transformer Model for Near-CompletePrediction of Peptide Tandem Mass Spectra

Abstract Accurate prediction of peptide tandem mass spectra is essential for confident peptide identification. Existing deep learning models achieve high similarity to experimental spectra but remain constrained by fixed fragment dictionaries of common fragment ions, limiting the...

How the Land Speaks: “Native Culture” as Mediating Politics in Individual–Group Relationality

Abstract Indigenous peoples are often valorized as automatically politicized collective subjects, backgrounding the precise mechanics of individual-to-group political formation. In the case of “Native Hawaiian culture”, a locally invoked category of norms, practices, and knowledg...

Carrying Firearms and Suicide Risk Among Adolescents

Importance Firearms are the most lethal method of suicide across all ages, with case fatality rates exceeding 90%, warranting urgent public health concern. Understanding how carrying of firearms by adolescents and suicide risk vary by race and ethnicity and by stringency of state...

The rise of carnivoran mammals in Europe through the lens of body mass

Carnivoran mammals (cats, dogs, bears, seals, etc.) and their kin radiated during the Palaeogene, among other carnivorous clades (hyaenodonts, mesonychians, and oxyaenodonts). This radiation has often been framed as a competition ultimately won by carnivorans, but the data suppor...

Hydration-dependent exciton-phonon coupling in a metal-organic framework photocatalyst

Abstract Metal-organic frameworks (MOFs) have potential for light-harvesting applications owing to their tunable optoelectronic properties via building block selection. The presence of bound solvent in MOFs is known to impact gas adsorption properties, but little is known about t...

Pike Use in Megafauna Hunting and Antipredator Defense: Historical Techniques and Paleolithic Research

This paper presents a comprehensive assessment of megafauna confrontation using pikes, as recorded in historical accounts and ethnographic studies depicting techniques of hunter-gatherers, pastoralists, colonial hunters and others. In contrast to the two other basic spear types,...

Hidden Cost of Re-Engagement: Workload in Dynamic Multi-Operator Supervision of Autonomous Systems

Autonomous systems are increasingly shifting from single-agent oversight to distributed fleet supervision, where operators alternate between monitoring, waiting, and brief intervention. We examined whether multi-operator, multi-agent supervision preserves objective performance wh...

Slow change blindness from serial dependence: slowly changing objects are perceived as biased toward the past

Abstract Background Slow change blindness, when attentive observers fail to notice large changes that happen gradually, raises questions about how visual information is combined across time. One plausible integration strategy is serial dependence: blending information from the re...

The evolution of genetic drift over 50,000 generations

Abstract Random variation in reproductive success–genetic drift–profoundly shapes genetic diversity and evolutionary trajectories. The strength of drift depends on the variance in descendant number, σ2d, which governs key evolutionary outcomes: for instance, the establishment pro...

Opioid-induced respiratory depression or oversedation risk assessment in hospitalized patients with cancer receiving palliative care

Purpose The Oversedation Risk Criteria (ORC) is a prediction model that estimates prescription opioid-induced respiratory depression (OIRD) or oversedation risk in hospitalized patients. The study objectives were to estimate OIRD/oversedation risk via the ORC and to determine the...
