Capturing the Epistemic Uncertainty in Subduction Earthquake Rupture Parameters

ABSTRACT Subduction earthquakes are highly destructive and can trigger devastating tsunamis, highlighting the need for a consistent probabilistic seismic-tsunami hazard assessment. However, current approaches treat both hazards separately: tsunami models use static coseismic slip...

Seasonal biogeochemical cycling of permeable sediments in a temperate shelf sea environment

Abstract In highly productive shelf-seas, permeable sediments cover the majority of the benthic environment. However, most research has focussed on shallow environments where currents, tidal flows, terrestrial inputs and benthic productivity have a greater influence than in sedim...

Near-Term Performance Early Warning in Building Projects Using XGBoost and Earned Value Metrics

Abstract Machine learning can contribute to more proactive, data-driven construction project management. However, most research efforts have focused on predicting final project outcomes, which may miss short-term variations that reveal emerging risks, thereby limiting the utility...

EduCase: A Systematic Framework for Developing Educational Case Studies in Construction and Engineering Education

Abstract Despite the critical role of educational case studies in construction and engineering education (CEE), there is a lack of systematic frameworks for developing effective educational case studies. This study introduces the educational case study development (EduCase) frame...

Researching from the Border: Methodological Decisions, Positioning and Challenges in the Study of Border Impact

Defining border as a phenomenon that articulates social dynamics brings certain challenges in terms of application to the development of research in border studies. In this paper, we review the theoretical and methodological decisions that sought to put this conception of border...

Eleven questions on Hantavirus cardiopulmonary syndrome management in the ICU

Hantavirus cardiopulmonary syndrome (HCPS) due to Andes virus (ANDV) is a fulminant yet potentially reversible cause of respiratory and circulatory failure requiring timely critical care. This article addresses eleven practical questions on ICU management, drawing on clinical exp...

Misunderstanding and Overprotection: The Impact of Research Ethics Committees on Social Disability Studies in Chile

This study explores the experiences of researchers in Chile when submitting disability-related projects to Research Ethics Committees. Through a qualitative approach involving 18 semi-structured interviews with researchers, the study identifies the barriers that arise from applyi...

Functional partitioning among core and peripheral bacteria shapes the giant kelp holobiont

The giant kelp Macrocystis pyrifera hosts diverse microbial communities integral to its ecological function, yet the distribution of microbial functions across different holobionts remains poorly resolved. Here, we used genome-resolved metagenomics to examine how microbial occupa...

Mating-Induced Behavioral Changes in Female Drosophila Are Modulated by Serotonin

Mating influences the physiology of female animals and induces changes in behaviors associated with securing resources for their offspring. Modulatory neurotransmitters are known to adjust behavioral responses of animals according to environmental cues and internal physiological...

The Resilient and the Vulnerable: Root-Associated Fungal Communities in the Regeneration of Nothofagus pumilio Forest Eight Years After Fire

Wildfires are increasing in frequency and severity worldwide, with long-lasting effects on forest vegetation and fungal communities essential for seedling establishment and forest resilience. Nothofagus pumilio, the dominant tree of South American temperate forests, forms key fun...

Tackling Waste of Fruits and Vegetables in Chilean Households with Tailored Informational–Enablement Interventions: A Randomized Controlled Pilot Study

Randomized Controlled Trials (RCTs) and direct measurement of waste are the gold standards for evaluating food waste interventions. This pilot RCT explored the effects of a 3-week tailored informational–enablement intervention to reduce the causes and amount of fruit and vegetabl...

Consumption infrastructure, retail urbanism and the production of space in Santiago

This article examines how shopping malls operate as key agents in the production of urban space in Chile. Drawing on Lefebvre's trialectics of space and Soja’s spatial dialectics, the study conceptualizes malls as infrastructures of urban centrality, governance, and meaning-makin...

FT-IR–based strategy for Streptococcus pneumoniae serotyping using machine-learning classifiers

Rapid serotype identification of circulating Streptococcus pneumoniae is essential for both effective epidemiological surveillance and clinical management. The gold standard serotyping method (Quellung reaction) is time-consuming, labor-intensive and expensive. Fourier transform...
