INTRODUCTION Research on the pathophysiology, complications, and management of young-onset type 2 diabetes has accelerated in the past decade due to increasing prevalence and incidence observed in many parts of the world, and a growing recognition of the more adverse prognosis compared with later-onset type 2 diabetes. The COVID-19 pandemic has highlighted the vulnerability of young individuals with type 2 diabetes, who were less likely to survive than age-matched peers without diabetes.

Abstract The damage and ignition response of a novel propellant is investigated using a modified split Hopkinson pressure bar (SHPB). The mechanical response of the propellant exhibits strong strain rate dependency following a power law. The whole process from mechanical damage to onset of ignition, deflagration and potential deflagration to detonation transition (DDT) under different strain rates (1000–5000 s−1) is captured via high-speed photography and digital image correlation (DIC).
