Chase-and-escape motion,which is a typical behavior between a predator and prey,is an important dynamics in animate systems.It has been concerned recently in optics aiming for achieving novel light steering and switch...
Various hydrogels have been explored to create minimally invasive microneedles(MNs)to extract interstitial fluid(ISF).However,current methods are time-consuming and typically require 10–15 min to extract 3–5 mg of I...

Weak cementation between natural gas hydrates and mud–sand seriously affects the solid-fluidized mining of natural gas hydrates. In this study, we analyze the debonding of natural gas hydrate sediment (NGHS) particle...
Future missions to the Moon and beyond are likely to involve low-thrust propulsion technologies due to their propellant efficiency.However,these still present a difficult trajectory design problem,owing to the near co...
