Construction of personal health knowledge graphs for clinical data harmonization in breast cancer

Integrating heterogeneous personal health data and maintaining clinical registries for breast cancer management is labor-intensive. This study presents an AI-powered virtual assistant transforming identifiable breast cancer patient data into interoperable personal health knowledg...

Who Believes Sexuality Myths? Sociodemographic, Motivational, and Sociocultural Predictors of Sexuality Myth Endorsement and Its Connection to Sexual Well-Being

Sexuality myths, that is, incorrect beliefs about sexuality, are argued to have individual and societal consequences. Yet we do not know who is particularly susceptible to these beliefs. Existing frameworks have centred on information deficits (e.g., due to missing sex education)...

Global dimensions of local geodesic ghor algebras

A ghor algebra is a path algebra with relations of a dimer quiver on a compact surface. We show that the global dimension of any cyclic localization of a geodesic ghor algebra on a genus g ≥ 1 surface is bounded above by 2 g + 1 . This number coincides with the Krull dimension of...

A nutrient-sensitive CPT1C-ABHD6 axis regulates BMP homeostasis and endolysosomal function in hypothalamic neurons

The endolysosomal system is central to neuronal homeostasis, yet how nutrient sensing regulates endolysosomal lipids remains poorly understood. Bis(monoacylglycero)phosphate (BMP), a signature phospholipid of late endosomes, is required for intraluminal vesicle formation, cholest...

Arf rings, simple singularities, and reflexive modules

Abstract In a pandemic era preprint, Dao showed two remarkable properties of Arf rings: under some mild conditions, they admit finitely many indecomposable reflexive modules up to isomorphism and every reflexive module is actually isomorphic to its own dual. In fact, the latter p...

Physiological determinants of endurance capacity in individuals with cerebral palsy: a narrative review

OBJECTIVE: To synthesize evidence on the physiological determinants of endurance capacity in individuals with cerebral palsy. DESIGN: Narrative review. SUBJECTS/PATIENTS: Children and adults with cerebral palsy across the spectrum of motor function (Gross Motor Function Classific...

Saponins induce lipid-dependent structural heterogeneity and modulate membrane organization in phospholipid bilayers

Abstract Saponins are amphiphilic natural compounds whose membrane activity is commonly attributed to sterol complexation, whereas their effects on sterol-free membranes remain poorly understood. Here, we investigated how lipid packing governs the interaction of a Saponaria offic...

What makes speech sound non-native?

Abstract This study investigates how monolingual listeners evaluate the perceived nativeness of bilingual speech in the first (L1) and second language (L2), and which pronunciation cues underlie these judgments. English and German listeners rated the L1/L2 speech produced by L1 E...

Populism and impatience

Abstract We develop a model where highly impatient voters are more likely than others to be subject to institutional frictions in the form of binding borrowing constraints. As impatient, borrowing-constrained voters cannot move long-term policy gains to the present, they turn to...

Multimodal imaging reveals no evidence for magnetite-based magnetoreceptors in the mole-rat eye

Magnetoreception is widespread across animals, but its sensory mechanism remains unresolved. One leading hypothesis proposes that single-domain magnetite is coupled to mechanosensitive ion channels. In subterranean Ansell's mole-rats, such receptors have been proposed to reside i...

Pathways to premium: How habits and benefits shape conversion and retention in freemium subscription models

Abstract Numerous digital services rely on freemium models, yet the mechanisms that move users from free usage to premium subscriptions remain poorly understood. This research examines how expected benefits of premium access, experienced benefits during trials, and habit developm...

Heart rate variability and physician performance during airway management simulations: an exploratory pilot study

OBJECTIVE: To examine the association between heart-rate variability (HRV) and physician performance during airway management simulations in two physician cohorts studied under different HRV measurement conditions. METHODS: This exploratory pilot study included otolaryngologists...

Global inequality in vaccine access, mortality and economy: An agent-based exploration

We develop an agent-based model to study the economic and public health impact of global vaccine inequality. Our model contains two world regions (higher-income vs. lower-income) and captures the co-evolution between economic activity, the spread and evolution of a hypothetical n...

Fast post-ploughing recovery of traditionally managed semi-natural mountain grasslands in the Romanian Carpathians

Mountain hay meadows are among the most species-rich grassland habitats in Europe, yet many have been historically ploughed and later re-established under traditional management. We examined the legacy effects of past ploughing on plant diversity, vegetation composition, and soil...

Effects of heat exposure on self-reported heat strain symptoms among pregnant and postpartum women in South Africa

Abstract Heat exposure can harm pregnant and postpartum women, yet heat strain symptoms in this population remain underexplored. This study implemented a novel mobile application and assessed the environmental context of five self-reported heat strain symptoms: skin rashes, sleep...

Exceptional points, lasing, and coherent perfect absorption in Floquet scattering systems

Abstract Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of electromagnetic waves from spatially finite PTCs using the multispectral Floquet scattering mat...

Sorgende Gemeinschaften: Performative Praxis des Miteinander-Sorgens

This article examines how “other caring communities” emerge through collective action and in response to the current crisis of care. It explores how these communities take shape through performative and embodied practices of caring with in everyday life under conditions of social...

Computational Detection of Implicit Philosophical Authority in Eustratius of Nicaea: A Pilot Study

Abstract: Byzantine engagement with ancient philosophical sources is well documented in cases of explicit citations, but implicit borrowing—unmarked by citation—has so far not seen a systematic study. This paper presents a computational pipeline for detecting such implicit author...

Invited perspectives: Towards usable compound event research

Abstract. Supporting stakeholders with science-based decision-making to mitigate and adapt to climate change impacts is a central mandate of the climate research community. In particular, mapping out scenario-dependent climate risk landscapes is one of the most pressing challenge...

Why are most people more creative than others? Exploring the better-than-average effect in creativity

People tend to rate themselves as more creative than average, but how this better-than-average effect (BTAE) generalizes across creativity aspects and which individual differences predict it remains unclear. In two online studies (N = 700), participants evaluated themselves relat...
