Background Topographic depressions within agricultural fields contribute disproportionately to regional nitrous oxide (N 2 O) emissions. These low-lying areas accumulate nutrients and fine particles through water inflow and erosion, creating conditions conducive to elevated N 2 O emissions. Because depressions remain part of fields, understanding how crop presence and management influence their N 2 O source strength is essenti...

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.
