A portable bill recognition product for blind users in the market “Note Teller 2” [].

Six Teller acuity cards showing varying grating widths from fine (on left) to coarse (on right). Note “peephole” in center of each card for observation of eye movement.

Wavelet power (A) and cross-wavelet coherence (B) for an exemplary trial. The length of the trial was 60 s (x-axis); consequently, the joke time, half-joke, two-person exchange and utterance time scales were 6, 3, 1.5, and 0.75 s (y-axis periods). In the top plot, note power has concentrations at these joke event time scales. In the bottom plot, coherence magnitude and relative phase at a given time scale and a point in time are denoted by color and the orientation of the arrow (pointing right: teller–listener inphase; left: teller–listener antiphase; down: teller leading by 90^∘), respectively. The average of these values at a given time scale were extracted from these plots to perform the time scale coherence and relative phase analyses.

Statistical evaluation of peptide probabilities. (A) Correlation between sumZscore and P_m for the complete set of 8,438 peptides identified using Peptide Teller to annotate features. (B) Vertical scatter plots illustrating the log intensity distributions of peptides from different regions of the plot in panel A. Blue datapoints are from EP samples and brown datapoints are from IUP samples. Horizontal lines indicate average values for these groups. Note that the multiple peptides shown for each group are not necessarily from the same protein and therefore may exhibit opposing trends. There is no or minimal overlap of peptide levels for the two outcomes in group I and II, and extensive overlap in groups III and IV.
