Abstract Evolutionary relationships within the Melastomateae, a diverse tribe within the Melastomataceae, are not yet completely resolved, and some putatively paleoendemic taxa that might alter relationships are still unsampled. This study employs a phylogenomic approach, utilizing target capture data, to revisit generic relationships and shed light on

Immersed superhydrophobic surfaces: Gas exchange, slip and drag reduction properties [PDF]
Superhydrophobic surfaces combine high aspect ratio micro- or nano-topography and hydrophobic surface chemistry to create super water-repellent surfaces. Most studies consider their effect on droplets, which ball-up and roll-off.

The stratigraphic biography of an archaeological site. Timing depositional events
Abstract The stratigraphic sequence of an archaeological site constitutes its biography, which details what was deposited, when it was deposited, and how the deposition occurred. However, many current methods of recording archaeological stratigraphy do not allow for a full reconstruction of a site's biography.
