Fragility of steel transmission monopoles under hurricane wind loading: Part II - Dynamic framework and comparative assessment

This preprint extends the parametric fragility framework of Part I to the dynamic response of steel transmission monopoles to turbulent hurricane wind. Wind loads are described by Kaimal spectra, the response is obtained by modal superposition, and failure is the first exceedance...

Photomapping electrically coupled networks of the mature thalamus and cortex

Electrical synapses are expressed ubiquitously across the brain and are crucial components of active neural circuitry and connectomes. Identification of coupled networks in living tissue is limited by technical demands of multiplexed recordings, and no dyes, fluorescent reporters...

Corrosion-induced cracking behaviour of RC beams: experimental investigation, empirical modelling, and finite element analysis

This study investigates corrosion-induced cracking in reinforced concrete (RC) beams through experiments, empirical modelling, and finite element (FE) analysis. Specimens corroded using the galvanostatic (GS) and artificial chloride environment (ACE) methods were examined using X...

Can small modular reactors clear the cost screen for Greek noninterconnected islands: A benchmark screening assessment against oil based supply with illustrative renewable storage evidence

Greek noninterconnected islands remain economically distinctive because several still depend on autonomous oil based generation while facing pressure to decarbonize through renewables, storage, and interconnections. This article addresses a limited screening question. Do small mo...

Determinants of the continuum of maternal healthcare service utilization in Nigeria: Evidence from the 2024 Nigeria Demographic and Health Survey

Background Maternal mortality remains a major public health challenge, particularly in low- and middle-income countries, with Sub-Saharan Africa bearing a disproportionate burden. Nigeria accounts for over one-quarter of all maternal deaths worldwide. This reflects gaps in access...

Temporal proximity to counseling is associated with longitudinal bedaquiline and antiretroviral therapy adherence in multidrug-resistant tuberculosis and HIV treatment

Background Medication adherence is a persistent challenge in the treatment of multidrug-resistant tuberculosis (MDR-TB) and HIV. Routine counseling notes are an underutilized source of information on patient adherence context. Methods We applied natural language processing (NLP)...

Crystals in rhyolitic melts can nucleate multiple bubbles: an experimentally constrained model

Abstract Heterogeneous nucleation of bubbles on crystals in magma is thought to be an important driver of volcanic eruptions. Decompression experiments were carried out to elucidate the kinetics of H 2 O bubble nucleation on crystals of different sizes. Samples used were mixtures...

Struvite as a Multiphase Catalyst in Radical-Driven Aqueous Transformations: Evidence from Guaiacyl Acetone Photochemistry

Abstract Struvite (NH4MgPO4·6H2O), a wastewater-derived mineral proposed as a slow-release fertilizer, may also influence aqueous photochemical transformations of organic matter. This study investigates the role of struvite in radical-driven reactions using a model system contain...

Different Last Millennium El Niño Southern Oscillation Sea Surface Temperature Patterns Drive Disparate North Atlantic Tropical Cyclone Characteristics

Abstract Understanding the relationship between the El Niño‐Southern Oscillation (ENSO) phenomenon and North Atlantic tropical cyclone (TC) activity is critical for both seasonal predictions and future projections of TCs. Unfortunately, the satellite observational era (1970‐pres...

Profiles of White Nationalist Beliefs and Parenting in Conservative Parents: Implications for Adolescent Beliefs and Well‐Being

ABSTRACT Introduction Despite the growing threat of far‐right extremist and White nationalist beliefs in the United States, little is known about parenting factors associated with the development of these beliefs during adolescence. Using a person‐centered approach, this study ex...

A multi-site benchmarking framework for scalable extraction of geriatric care constructs from electronic health records

Current Natural Language Processing (NLP) algorithms for detecting geriatric conditions are largely limited to domain-specific models that fail to capture the interdependent, multidimensional nature of comprehensive geriatric assessment. This study aimed to develop and evaluate a...

Hyperpolarization-activated cation channels confer tonotopic specialization for temporal encoding of sound frequency in the cochlear nucleus

Sensory neurons are equipped with physiological properties vital for accurate signal processing. The functional importance of such properties is exemplified in auditory circuits where intrinsic excitability is optimized to detect frequency-specific features. In birds, the neurons...

From Structural Inequalities to Labor Precarity: Adoption of Digital and AI Tools in Latin American Journalism

While inequalities in technological access and use have been widely documented, few studies have examined their link to labor precarity and social inequality in journalism in the Global South. This article analyzes this relationship through a multilevel study of Worlds of Journal...

Hype vs. reality: the true impact of traditional and generative AI on users’ intention to use soft skills coaching chatbots in higher education

This study compares three soft-skills coaching chatbot configurations in higher education: traditional AI, hybrid AI, and generative AI-only systems. In collaboration with Rocky.ai, a prominent European AI coaching chatbot company, we investigate a sample of 120 higher education...

Autophagy induction mitigates FUS aggregate formation and early synaptic dysfunction at the NMJ in a FUS-ALS model

Mutations in Fused in Sarcoma (FUS), a RNA binding protein, cause Amyotrophic Lateral Sclerosis (ALS). ALS is an aggressive neurodegenerative disease resulting in motor neuron degeneration. Defects in synaptic integrity precede neuronal loss in ALS, but the mechanisms responsible...

Sovereigntism and the emerging politics of eternity in Mali

This paper examines the political imaginaries underpinning Mali’s dramatic rejection of liberalism in the wake of Mali’s most recent military coups in August 2020 and May 2021. Mali’s post-democratic leaders have skilfully employed these imaginaries to gain public support and sho...

Multi-objective optimum life-cycle management and decision-making for deteriorating structures: review and future directions

Civil structures deteriorate under continuous exposure to external loads, mechanical and environmental stressors, and extreme events throughout their service life. The high uncertainty associated with these factors complicates the accurate prediction of structural performance and...
