Reproductive success is associated with age in many taxa, increasing in early life followed by reproductive senescence. In socially monogamous but genetically polygamous species, this generates the interesting possibility of differential trajectories of within‐pair and extra‐pair siring success with age in males. We investigate these relationships simultaneously using within‐individual analyses with...
This article reviews amicroscopic theory to compute gain and absorption spectra of semiconductor quantum-well structures. The single-particle energies (band structure) are calculated by using LuttingerKohn theory in the envelope function approximation. The Coulomb-interacting electronhole plasma in the laser gain region is treated at the level of quantum-kinetic equations in the Markov limit. Examples...
