Kinship Systems and the Structure of Political Succession: Evidence on the Relative Association of Descent and Residence

Kinship systems are widely recognized as central institutional structures shaping social and political organization, yet it remains unclear which dimensions of kinship are most closely associated with the institutionalized succession to political office, and in particular with th...

Three-dimensional circulation controls on pollutant retention and mucilage accumulation in the sea of Marmara: A Lagrangian perspective

The Sea of Marmara is undergoing a severe marine pollution crisis driven by chronic nutrient enrichment and recurrent mucilage outbreaks. The physical mechanisms controlling transport, accumulation and persistence of pollutants and organic matter remain insufficiently resolved. H...

High-Flow Nasal Cannula Outcomes in COVID-19-Associated Acute Hypoxemic Respiratory Failure: Illness Severity, Awake Prone Positioning, and Risk of Intubation in a Single-Center ICU Cohort

Background and Objectives: High-flow nasal cannula (HFNC) is widely used in acute hypoxemic respiratory failure, yet predictors of successful noninvasive support and the role of awake prone positioning remain incompletely defined, and observational analyses are vulnerable to immo...

Circulating Soluble Urokinase Plasminogen Activator Receptor and C-Reactive Protein Concentrations in Adults with High-Functioning Autism

Background: Immune dysregulation has been implicated in the pathophysiology of autism spectrum disorder (ASD). Soluble urokinase plasminogen activator receptor (suPAR) is a stable biomarker of chronic immune activation that has not previously been investigated in ASD. We compared...
