Advancements in technology are regularly identified, assessed, and classed into emerging and/or potentially disruptive technologies, according to their ability cause disruptions defence systems, defence. Perhaps this is because capabilities centre on grand systems deployed at the level of nations. Hypersonic missiles one example. The testing a new hypersonic missile or research program types dr...

We examine the evolution and maintenance of defence and conspicuousness in prey species using a game theoretic model. In contrast to previous works, predators can raise as well as lower their attack probabilities as a consequence of encountering moderately defended prey. Our model predicts four distinct possibilities for evolutionarily stable strategies (ESSs) featuring maximum crypsis. Namely ...
