Article Synopsis
- Road traffic injuries (RTIs) are a significant global health issue, ranking as the eighth leading cause of death, with India particularly affected among younger populations, prompting an analysis of Tamil Nadu's Road Accident Data Management System from 2011-2016.
- The study found a decline in the incidence of road traffic accidents (RTAs) and RTIs over the five-year period, with the majority of injuries occurring in males aged 20-39, and most accidents happening on state highways and Sundays.
- Key findings indicate that age-adjusted incidence rates decreased significantly, with motorcyclists and pedestrians being the most at risk, highlighting the need for targeted interventions to protect vulnerable groups and reduce RTIs.
Millijoule-scale pulses of multicycle terahertz radiation (MC-THz) are increasingly being pursued as drivers for applications requiring high-fields and high spectral brightness. An attractive approach for generating high peak-power MC-THz pulses is nonlinear optical down-conversion of laser pulses in periodically-poled crystals. A principal limitation to the yield, however, is the small (sub-centimeter) apertures of commercially-available crystals which restrict the amount of laser energy that can be used.
