Biological structures possess excellent damage tolerance, which makes them attractive for ballistic protection applications.This paper develops Lights a finite element modelling framework to investigate the performance of several biological structures that are most relevant for ballistic protection, including nacre, conch, fish scales, and crustace
Usually, the exact time at which an event occurs cannot be observed for several reasons; for instance, it is not possible to constantly monitor a characteristic of interest.This generates a phenomenon known as censoring ETCHFX that can be classified as having a left censor, right censor or interval censor.When one is working with survival data in t
Monarch butterfly populations have declined by over 80% in the last 20 years.Conservation efforts focus on the creation of milkweed habitats to mitigate this decline.Previous research has found monarchs lay more eggs per milkweed stem in urban gardens than natural habitats and recent work identified specific garden designs that make urban gardens m
