Because of the roughly linear correlation between Be/H and Fe/H in low metallicity halo stars, it has been argued that a “primary” component in the nucleosynthesis of Be must be present in addition to the “secondary” component from standard Galactic cosmic ray nucleosynthesis. In this paper we critically re-evaluate the evidence for the primary versus secondary character of Li, Be, and B evolut...

The 14 Bravais-lattice types are at the very heart of crystallography, learned in Chapter 1 of any introductory course on the topic. It is somewhat remarkable that, in the second decade of the 21st century, we may still learn new things about them, but Hans Grimmer's paper Partial order among the 14 Bravais types of lattices: basics and applications (Grimmer, 2015) does this and provides us wit...

In this paper we present an analysis of revival actions in a third person shooter video game. We observe that players who revived their teammates played significantly more sessions. They appear also to be more skilled and successful in the game in terms of kills, wins, and deaths. We then discuss how to extend our analysis methodology to other types of social play as well as other games. Author
