We review recent developments in the study of volcanism and tectonics on Venus. Venus’s crust is basaltic, dry, and probably about 30 km thick. The mantle convects, giving rise to plumes, and has a similar composition and mean temperature (∼1300◦C), but a higher viscosity (∼1020 Pa s), than that of the Earth. Inferred melt generation rates constrain the lithospheric thickness to between 80 and ...

A frotheria is one of the most remarkable hypotheses in mammal evolution. It suggests that one-third of the orders of placental mammals form an ancient group that evolved on Africa when that continent was isolated from others through plate tectonics (1). Although this hypothesis has been predicted by molecular clock studies (2), evidence for it has emerged only in the last 3 years from phylogen...

The visualization of spatial information for wayfinding assistance requires a substantial amount of display area. Depending on the particular route, even large screens can be insufficient to visualize all information at once and in a scale such that users can understand the specific course of the route and its spatial context. Personalized wayfinding maps, such as μMaps are a possible solution ...

OBJECTIVES The study sought to identify the varied types of change arising from internal and external influences in assisted living (AL) settings, expanding upon the literature's limited focus on resident decline and staff turnover and clarifying the importance of changes to life and work there. METHOD This analysis employed qualitative interviews and observations from 4 studies involving 17 ...

These days 3d models are used in a huge variety of applications and the demands in quality and quantity are steadily growing. At the same time, the extraction of man-made objects from measurement data is quite traditional. Often, the processes are still point based, with the exception of a few systems which allow to automatically fit simple primitives to measurement data. The need to be able to...
