Ternary coding

This ternary coding has some limitations in particular, it may affect the ability of the system to derive general rules. The coding described in this chapter, which relates to work by John Holland, has been successfully used in a variety of applications and has the advantage of simplicity. Readers who wish to explore alternative ways of representing classifiers will find them described in recent papers on classifier systems.

Fig. 11.17 Chronoamperometric screening results from the ternary catalyst library described in Figs. 11.15 and 11.16. Surface-area-normalized activity values of each individual composition are plotted as a function of composition. Color-coding indicates activity red = high, blue = low. The pt-Ru binary compositions are connected by a solid line to underscore the activity trends observed in this binary system. Conditions 1 M methanol, 0.5 M H2S04, 550 mV/RHE, 5 min.

Figure 16 Structure of the ternary electron-transfer complex of MADH, amicyanin, and cytochrome c-551 (pdb code 2MTA). The copper atom of amicyanin is 9.4 A from the edge of Trp 108 in the electron donor MADH and 24.7 A from the electron acceptor iron atom in cytochrome c-551...

Mixtures of HCTA, PEPA were prepared in TFA-CH2CI2 (0 4 v/v). Visual observations of these ternary mixtures are recorded in Table XIV. The solution coded H-4 phase separated after 2 weeks into isotropic and anisotropic phases. 

Na-Mg) interactions for mixtures (NaCl -h MgCl2) are related to and the ternary interactions (Na-Mg-Cl) are related to The Pitzer s equations thus incorporate Young s rule in all of its formulations. This general approach, although somewhat complicated, can account for all the possible interactions in a stepwise manner. Computer codes have been written that can be used to estimate the physical-chemical properties of natural waters over a wide range of temperatures (0-100 °C) and ionic strengths (0-6 m) (Millero, 2001). 

The n diagonal elements ij(a,b) of the matrix s(a,b) are encoded by concatenating them into a single number. For example, a diagonal of elements (2, 2, 1, 2, 0, 2 ) is encoded as the decimal number 221202. (Since the only numerical values that occur along the diagonal are 0, 1, and 2, a ternary number system can also be used). The number so obtained is the second component C2(s(a,b)) of the shape code vector c(s(a,b)). 

We predicted their behavior earlier using infinite-dilution /f-values, with the results at 1 atm shown in Table VIII. Only the acetone and chloroform appear to display azeotropic behavior. With this information and that for pure species boiling points at the pressure of interest, we can sketch the ternary diagram for this mixture. We can also use a computer code to generate it, which was done for Fig. 25. We see that there is one maximum-boiling azeotrope between acetone and chloroform. 

Simple arithmetic indicates that the genetic code cannot be binary since there are only four bases in RNA (A, G, C, and U), yet 20 different amino acids (19 amino acids and 1 imino acid) are known to exist in cells. Therefore, the number of possible combinations using just two bases in the codon is not enough. For example, four bases in the first position and four bases in the second position would only be sufficient to encode 16 possible amino acids (4 4 = 16). However, a ternary- (or triplet-) based code would be more than enough by specifying 64 possible amino... 

Two tests to determine whether the ternary complex, protein-synthesizing ribosome, mRNA, and peptidyl-tRNA, is destabilized or stabilized were conducted in the presence of erythromycin. The stabilization of the ternary complex was confirmed by the profile of the footprint of the ribosome occupying the ermC message covering the leader peptide coding region [183]. 

Another application, to return to the solubility example, might be the introduction of a low level of a salt, or of a surface active substance to the ternary system. This will have very little effect on the other components and so can be treated as a (coded) independent variable, Z in one of the above "mixed" models.
