Linking molecular composition of organic aerosols to reactive oxygen species formation using an MCR-VK framework

Abstract. Reactive oxygen species (ROS) formation by atmospheric fine particulate matter (PM) is widely implicated in adverse health effects, yet the molecular determinants of particle-level ROS formation remain poorly constrained, largely due to the chemical complexity of organi...

What AI Cannot Give Gifted Learners

Generative artificial intelligence (AI) has entered gifted education faster than the field has decided what it changes. This conceptual article argues that the pedagogical question is not whether AI helps. It is which cognitive work stays with the learner. Two claims follow. Firs...

Assessing Behavioral and Environmental Facets of Obesity Unobtrusively Utilizing Digital Tools: Introducing the BETTER4U Indicators

ABSTRACT Understanding obesity involves evaluating numerous contributing factors. Collecting the necessary data for this can impose a significant burden on both research participants during clinical studies and real‐life deployments of digital tools aiding obesity management. The...

Long-term incidence and predictors of in-stent restenosis after chronic total occlusion percutaneous coronary intervention: a cohort study

Background In-stent restenosis (ISR) remains a major limitation after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs). However, long-term patency data after chronic total occlusion (CTO) PCI are limited despite high ISR risk. We evaluated long-term ISR in...

Condensation Sink Efficiency of Atmospheric Particles Regulated by Their Chemical Compositions and Hygroscopicity

Abstract Condensation sink (CS) from atmospheric pre-existing particles is a crucial limiting factor for the occurrence of new particle formation (NPF). However, intense NPF events occur frequently in polluted urban areas despite high CS levels. Here, to address this discrepancy,...

Discovery and Design of YTHDF2-Selective and Pan-YTHDF Inhibitors for m6A Binding by the YTH Aromatic Cage

Abstract Recognition of N6-methyl-adenosine (m6A) in the RNA sequences by the YT521-B homology domain-containing protein family paralogs 1–3 (YTHDF1–3) is a dominant layer of myriad cellular regulation. Dysregulated YTHDF paralog expression and activities have been reported in ca...

First year student teachers’ perceptions of technology education: The relationship between general teaching, functional learning goals and technical learning

Abstract The aim of this article is to examine first year student teachers’ perceptions of technology education. Being aware of the perceptions needed for teacher education to support their growth in comprehensive technology education teaching and developing the teacher education...

The afterlives of the ‘migration crisis’ and its hidden labours: Ukrainian displacement post-2022

Migration has become increasingly synonymous with ‘crisis’. Drawing on longitudinal ethnographic fieldwork with Ukrainian nationals in Warsaw (2020–2025), this article asks what ‘crisis times’ mean for migration research methodologically and what remains obscured when forced disp...

Cholangioscopy in the diagnostic and therapeutic work-up of intraductal papillary neoplasms of the bile duct: a systematic review and meta-analysis

Background: Intraductal Papillary Neoplasms of the Bile Duct (IPNB) are rare and diagnostically challenging, particularly in assessing invasiveness and intraductal spread. Cholangioscopy offers promise through direct visualization and targeted biopsies. The aim of this study was...

Overlapping knowledge regimes of the EU and China: grassroots pragmatism in Kazakhstan

Geopolitical competition is reshaping the knowledge order, which is composed of overlapping knowledge regimes. This article examines how such competition manifests in the everyday practices of academic communities in the Global South. Focusing on Kazakhstan, which participates in...

Perils of the Paleocene: vertebrate and invertebrate induced bioerosion in freshwater turtles from Tiupampa, Bolivia (early Paleocene)

Abstract Turtles provide an important link between terrestrial and aquatic ecosystems, acting as both predators and prey, while also being an important host for a range of parasites. The dermal armor that characterizes the group ensures their abundance in the vertebrate fossil re...

Computational Study of Gas-Phase Reactions to Produce Sulfite Esters: A New Class of Sulfur Containing Molecules in the Atmosphere?

Abstract We use computational quantum chemistry to study gas-phase reactions of aldehydes with water and sulfur dioxide. We find that a new reaction leading to the formation of previously nearly unstudied sulfite esters is possible with a comparatively low barrier. The reaction c...

Wearable Health-Tracking Devices and Adherence to Physical Activity Guidelines Among US Adults, Including Those with Elevated Anxiety Symptoms: A Nationally Representative Cross-Sectional Analysis of HINTS 7 (2024)

Physical activity is a pillar of lifestyle medicine, yet most US adults do not meet aerobic guidelines, and inactivity is especially common among people with anxiety. Wearables enable self-monitoring, but population-level evidence linking them to guideline adherence among distres...

Drought responses of a Norway spruce forest on drained peat soil: combining sap-flow sensors, eddy-covariance, meteorological, soil and UAV data

Abstract. The summer of 2021 brought a severe drought to southern Finland. We explored how a drained boreal peatland forest responds to drought by combining a wide range of in situ monitoring and Unmanned Aerial Vehicle (UAV) remote sensing. A dataset combining eddy-covariance (E...

Alternative development in a post-aid world

In 2020, Liberian scholar-activist and author Robtel Neajai Pailey re-invigorated a debate about the colonial underpinnings of mainstream development and their racist logics with an influential journal article entitled ‘De-centering the “White Gaze” of Development’. She has since...

Gambling consumption and socio-demographic characteristics among help-seekers with gambling-related debt

Aims: Indebtedness is prevalent among people with gambling problems. However, little research has focused on socio-demographic characteristics and gambling consumption patterns of individuals who finance their gambling with loans. This study aims to identify how debt-financed gam...

Technical note: T c 1D – a 1D thermal and thermochronometer age prediction model

Abstract. Thermochronological data are commonly used to study the activity of geological processes over timescales of millions of years. Ages produced by thermochronological measurements, however, are non-unique and do not directly record rates of processes, which has led to the...

Gut microbial metabolism of peanuts generates immunoregulatory metabolites

Background. Complementary feeding practices and timing are thought to significantly influence early life immune development, with the early introduction of allergenic foods being especially important for prevention of food allergy. We hypothesized that allergen-containing foods s...

‘Pushing the crisis button’? Temporal space and institutional synchronization in Finland's COVID-19 governance

The article examines how the temporal space of a crisis is constructed, synchronized and contested within crisis governance. Drawing on conceptual history and recent scholarship on crisis temporalities, we introduce the concept of ‘institutional synchronization’ to capture the ac...

Outcome of Secondary Glaucoma in Eyes With Uveal Melanoma A Population-Based Analysis

Précis: Over 50% of eyes with uveal melanoma and secondary glaucoma with ≥20/400 vision retain that level through 5 years, and over 90% with <20/400 vision are pain-free. Over 90% avoid secondary enucleation for intractable glaucoma. Purpose: To report outcome of secondary glauco...
