In many instances candidate solution generators use the squared, power'ed or logarithmic random variable to obtain solution's index: this has an effect of giving more weight to better solutions. With some probability, an independent, algorithmically different, parallel optimizer is engaged whose soluti...
Partial eta squared was used to report effect sizes (η2 = 0.01 indicates a small effect; η2 = 0.06 indicates a medium effect; η2 = 0.14 indicates a large effect); the formula used is reported in statistics table. All statistical analyses are also reported in the ...
(seeMethods). The maximum star plus planet signal-to-noise ratio for a single-pixel spectrophotometric light curve is 617 at 1.14 μm, with the signal-to-noise ratio curve closely following the shape of the throughput-weighted stellar spectrum and reaching a minimum of 62 at 2.83 μ...

The SM Higgs boson couples to vector bosons, with an amplitude proportional to the gauge boson mass squared \({m}_{{\rm{V}}}^{2}\), and to fermions with an amplitude proportional to the fermion mass mf. Hence, for example, the coupling is stronger for the third generation of quarks...
