In the last 15 years or so, soft selective sweep mechanisms have been catapulted from a curiosity of little evolutionary importance to ubiquitous mechanism claimed explain most adaptive evolution and, in some cases, evolution. This transformation was aided by series articles Daniel Schrider and Andrew Kern. Within this series, paper entitled “Soft sweeps are dominant mode adaptation human genom...

Abstract The influence of second-order dispersion (SOD) on stimulated Raman scattering (SRS) in the interaction an ultrashort intense laser with plasma was investigated. More significant backward SRS observed increase absolute value SOD ( $\mid \kern-1pt\!{\psi}_2\!\kern-1pt\mid$ ). integrated intensity scattered light is positively correlated to driver pulse duration. Accompanied by side SRS, ...

In this paper, a model of electron electromagnetic radiation is established using Lorentz formula for the interaction tightly focused elliptically polarized laser with single under condition nonlinear Thomson scattering. Let initial pulse width $${\kern 1pt} \lambda_{0} {\kern 1pt}$$ be 3.3 fs. By changing $$L$$ , energy distribution and space emitted by different conditions are obtained. The r...
