Article Synopsis
  • Spintronic terahertz emitters (STEs) are powerful terahertz sources that can operate across a wide range of pumping frequencies, yet their performance is ultimately limited by their optical damage threshold.
  • Recent advancements in technology require STEs to pump at higher megahertz rates rather than the traditional kilohertz rates, highlighting a gap in research on this topic.
  • The study introduces a new classification of the optical damage threshold based on repetition rates and identifies temperature-driven inter-layer diffusion as the main failure cause, offering insights for improving STE performance in future applications.

Background: The increasing focus of population surveillance and research on maternal-and not only fetal and infant-health outcomes is long overdue. The United States maternal mortality rate is higher than any other high-income country, and Georgia is among the highest rates in the country. Severe maternal morbidity (SMM) is conceived of as a "near miss" for maternal mortality, is 50 times more common than maternal death, and efforts to systematically monitor SMM rates in populations have increased in recent years.

Heat-related illnesses (HRI) are the most frequent cause of environmental exposure-related injury treated in US emergency departments (ED). While most individuals with HRI evaluated in EDs are discharged to home, understanding predictors of individuals hospitalized with HRI may help public health practitioners and medical providers identify high risk groups who would benefit from educational outreach. We analyzed data collected by the Georgia Department of Public Health, Office of Health Indicators for Planning, regarding ED and hospital discharges for HRI, as identified by ICD-9 codes, between 2002 and 2008 to determine characteristics of individuals receiving care in EDs.
