Machine learning-based parameter adaptation approach for modeling hysteretic axial-shear-flexure interaction in RC columnsNARA Subscribed
Reinforced concrete (RC) members subjected to seismic loading experience variable axial forces and shear spans, which induce axial–shear–flexural interaction that governs their hysteretic behavior. Existing interaction models rely on complex constitutive assumptions such as smeared crack formulations, resulting in high computational demand and convergence difficulties, limiting their applicability for system-level assessments....
Purpose Head and neck cancer (HNC) is a heterogenous disease with substantial mortality. This study assesses the long-term epidemiologic landscape, demographic disparities, and survival outcomes of HNC. Methods Adult patients with primary HNC were identified in the Surveillance, Epidemiology, and End Results (SEER) database by International Classification of Diseases for Oncology (ICD-O) codes. The primary outcomes of this stu...

Earthworms Enhance Global Soil Carbon Storage Through Microbial–Mineral StabilizationNARA Subscribed
Earthworms play a dual role in the global carbon cycle: they accelerate organic matter decomposition yet are often associated with greater soil organic carbon (SOC) storage. However, uncertainty regarding the mechanisms and magnitudes through which earthworms concurrently influence SOC mineralization and stabilization has limited the integration of soil fauna into carbon models. Here, we synthesize 696 paired observations from...
