Of the donors in whom ovulation was triggered with hCG, 3.2% developed symptoms of moderate (2.2%) or severe (1%) ovarian hyperstimulation syndrome, while none of the IVF donor cycles that were triggered with the GnRH agonist presented ovarian hyperstimulation syndrome, needed coasting, or were cancelled.

Features are extracted from windows of the EEG by using short time Fourier transform. The total power spectrum is computed in five frequency bands and used as input to the MNG network. The results show that MNG outperforms simple neural gas in correctly detecting sleep spindles. In addition the temporal quantization results as well as sleep trajectories are visualized on two-dimensional maps by using the OVING projection method.

Among other results, we determine the holomorphic univalent maps hhh for which there exists c>0c>0c>0 such that every harmonic mapping of the form f=h+bargf=h+\bar{g}f=h+barg with ∣g′∣<c∣h′∣|g'|< c|h'|∣g′∣<c∣h′∣ is univalent. The notion of a linearly connected domain appears in our study in a relevant way.
