DOI: 10.1038/nature22351
Abstract: Two distinct forms of natural selection promote adaptive biological diversity. Divergent selection occurs when different environments favour different phenotypes, leading to increased differences between populations. Negative frequency-dependent selection occurs when rare variants within a population… read more here.

DOI: 10.1103/physrevb.104.125112
Abstract: In the framework of time-dependent density functional theory (TDDFT), the exact exchangecorrelation (xc) kernel fxc(n, q, ω) determines the ground-state energy, excited-state energies, lifetimes, and the time-dependent linear density response of any many-electron system. The… read more here.
