Spiral growth, two-dimensional nucleation, and the Ehrlich-Schwoebel effect
TL;DR: In this paper, a recent study of spiral growth in the presence of step edge barriers is presented, which leads to unconventionally shaped spiral hillocks that display the same characteristic ever-steepening height profiles as wedding cakes formed during growth by two-dimensional nucleation.

Effects of recombination on the evolvability, genetic diversity and mutational robustness of neutrally evolving populations
TL;DR: This study focuses on finite populations evolving on neutral networks, and concludes that conflicting trends induced by recombination can be explained by an emerging trade-off between evolvability and genetic diversity on the one hand, and mutational robustness and fitness on the other.

Non-equilibrium Roughness Evolution of Small Molecule Mixed Films Reflecting Equilibrium Phase Behavior.
Alexander Hinderhofer,Alexander Hinderhofer,Jan Hagenlocher,Alexander Gerlach,Joachim Krug,Martin Oettel,Frank Schreiber +6 more
TL;DR: In this article, the surface roughness of binary mixtures of several prototypical organic compounds was determined using X-ray reflectivity, and it was shown that the growth behavior can be rationalized by a lowered step edge barrier in the mixed films which is induced by reduced in-plane crystallinity.
Journal ArticleDOI
Reaction Kinetics in a Tight Spot
TL;DR: The standard analysis of reaction networks based on deterministic rate equations fails in confined geometries, commonly encountered in fields such as astrochemistry, thin film growth and cell biology as mentioned in this paper.

Geometry of fitness landscapes: Peaks, shapes and universal positive epistasis
TL;DR: In this article, the shape approach uses triangulations (shapes) induced by fitness landscapes for a large protein fitness landscape for an immunoglobulin-binding protein expressed in Streptococcal bacteria.
