Frequency conversionharmonic generation including higher-order harmonic generationMultiphoton ionization and excitation to highly excited statesWe demonstrate the efficient generation of sum and difference frequencies in the extreme-ultraviolet wavelength region both experimentally and theoretically. The importance ...
daily satellite Chl-awas temporally averaged to an 8-day week frequency and spatially averaged within each cluster. Subsequently, the phytoplankton austral spring-summer bloom was identified as the event, no shorter than 2 weeks, in which Chl-asurpasses a threshold...
Discrimination (2AFC) experiment (Lab): Stimuli were Gabor patch targets tilted −0.5° or +0.5° relative to vertical (50 ms presentation, 50% Michelson contrast30, Gaussian envelope σ = 0.42°, spatial frequency wavelength λ = 0.3°, random phase, 750 ms onset ±up to ...
"Materials are studied that initially do not conduct electricity at all," explains Prof. Joachim Burgdörfer from the Institute for Theoretical Physics at TU Wien. "These are hit by an ultra-short laser pulse with a wavelength in the extreme UV range. This laser pulse shifts the electrons in...
It is noted that there is no difference in the properties of type II burst like start frequency and end frequency between the solar cycle rise phase events and decay phase events. The mean CME speed of solar cycle decay phase events (1373???km???s???1) is slightly higher than the ...
