In our experiments, we set a threshold value for each parameter in order to bound the processing time of each FB.

The dictionary (i.e., plaintext space) is necessarily very small, since processing ℓ-bit words requires lookup tables of size O(2 ℓ )×O(2 ℓ )=O(22ℓ ) bits.2 Thus, to remain feasible, we are bound to processing chunks of up to 8 bits (and hardly more).
The two attentional systems are inseparably bound, while providing prioritized processing of relevant information.
This is optimal, since a lower bound for processing a sequence of size L is trivially Ω(L).
As a lower bound, we used a processing factor of 0.64 for hard and soft wheat, and available finished-food pasta data for durum wheat.
Among the major physiological targets of the Hmt1 methyltransferase are heterogeneous nuclear ribonucleoproteins (hnRNPs) [43], [44], which bind mRNAs during processing and export from the nucleus [7], [8].
In the case of nonseparable processing, the upper bound on the output of the s.p.e.d.d
Using the lower bound processing factor of 0.64 for hard and soft wheat, together with actual pasta occurrence data, gave a mean exposure (P*P) of 3.68 ng OTA kg bw−1 per day for 1-year-olds compared with 4.38 ng OTA kg bw−1 per day (Table 8), when the higher processing factor of 0.82 was used.
