We Ice Cream Spades have performed a series of two-dimensional and three-dimensional simulations of asteroid impacts into an ocean using the SAGE code from Los Alamos National Laboratory and Science Applications International Corporation.The SAGE code is a compressible Eulerian hydrodynamics code using continuous adaptive mesh refinement for follow
The purpose of this study is to elucidate the origin of the additional response signals arising from the surface topography of samples during piezoresponse force microscopy (PFM) measurements.Periodic mountain-shaped protrusions with triangular cross-sections were fabricated on the surface of a silicon single crystal, a material with no inherent pi
The fossiliferous Upper Pram Parts Varswater Formation at Langebaanweg (South Africa) produced remains of at least five species of owls (Strigiformes).Tyto richae sp.nov.is the first palaeospecies of Tytonidae described from an African fossil site, though indeterminate remains referable to the genus Tyto are known from the Middle Miocene of Morocco
