WebApr 14, 2024 · The acceleration of ultrathin targets driven by intense laser pulses induces Rayleigh–Taylor-like instability. Apart from laser and target configurations, we find that electron heating and surface rippling, effects inherent to the interaction process, have an important role in instability evolution and growth.
WebSep 27, 2024 · The method of moments estimator is easily θ ^ mom = X ¯. But if you want to estimate θ 2, you could either choose θ 2 ^ mom = ( X ¯) 2 or you could do it from the second sample moment; θ 2 ^ mom = 1 2 X 2 ¯. They're clearly not equivalent.
