Signatures of the sub-Rayleigh to supershear fracture transition in snow avalanche experiments [PDF]

Nature Communications
Snow slab avalanches occur when a crack propagates within a highly porous weak snow layer buried beneath a cohesive snow slab. Here, we report direct observations of a supershear event in snow fracture experiments following the spontaneous transition ...

Designing supply chains to meet the growing need of vaccines: evidence from four countries

Journal of Pharmaceutical Policy and Practice, 2021
Background Immunization supply chains (iSCs) move vaccines from manufacturer to point of use with the added complexities of requiring cold chain and an increasing need for agility and efficiency to ensure vaccine quality and availability. Underperforming

Association between multi-component initiatives and physical activity-related behaviors: interim findings from the Healthy Schools Healthy Communities initiative

BMC Public Health, 2021
Background Although successful, assessment of multi-component initiatives (MCIs) prove to be very challenging. Further, rigorous evaluations may not be viable, especially when assessing the impact of MCIs on long-term population-level behavior change (e ...
