Evolutionary drivers of temporal and spatial host use patterns in restio leafhoppers Cephalelini (Cicadellidae)
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Understanding how divergent selection results in the evolution of reproductive isolation (i.e. speciation) is an important goal in evolutionary biology. Populations of herbivorous insects using different ...
Aspects of femtosecond pulse shape transfer via difference frequency mixing
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: We investigate the generation of shaped femtosecond pulses in the infrared spectral regime via a nonlinear
process called di erence frequency mixing. First we develop a detailed model of the process,
...
