With regard to the stabilizing effect of the a-substituent at the silicon, the following gradation can be inferred from results of x-ray structures O > S > C > Cl. This sequence correlates with known Si-X bond energies. 

This sequence correlates quite well with the reactivity of these ions in the Haber-Weiss cycle of hydroperoxide decomposition. 

See Figure 8. HPLC equipment using reversed phase separation with fluorometric detection was used. Injection for correlation HPLC was accomplished with a newly developed device ( 4 ). The total range of phenol measured was five decades of concentration 0.01 -100 jug/L. The two higher concentrations (10 - 100 /i-g/L) were determined solely by conventional methods. The two lower concentrations (0.01 - 0.1 /xg/L) were determined by correlation HPLC with 16 and 3 sequences correlation time, respectively. Measurements at the 1 /xg/L level were carried out both by conventional and by correlation HPLC (1 sequence). The bars indicated on the calibration graph represent the peak area +3 (arbitrary units), where is the standard deviation...

It is worthwhile to note that in the reaction of the group 6B metal hexacarbonyls with the azide anion to provide isocyanatometallates, a concerted mechanism is proposed based on kinetic parameters which involves a three-centered transition state (7), and that the activation enthalpy is some 22.6 kJ lower for tungsten than for chromium (52). This reactivity sequence correlates with an increase in M-CO bond distances going from chromium to tungsten hexacarbonyl (53-55). 

The question of whether proteins originate from random sequences of amino acids was addressed in many works. It was demonstrated that protein sequences are not completely random sequences [48]. In particular, the statistical distribution of hydrophobic residues along chains of functional proteins is nonrandom [49]. Furthermore, protein sequences derived from corresponding complete genomes display a distinct multifractal behavior characterized by the so-called generalized Renyi dimensions (instead of a single fractal dimension as in the case of self-similar processes) [50]. It should be kept in mind that sequence correlations in real proteins is a delicate issue which requires a careful analysis.

Collectively, results from sequence-correlated solvent accessibility, direct distance measurement, and disulfide cross-linking rates all suggest that the crystal and solution structures are similar in the Cl region. 

The next step in the description of the DNA sequence is the analysis of the pair-wise nearest-neighbor correlations Cy, for example, the normalized probabilities to And successive pairs of the nucleotides i and j. Eor all 16 possible successive dinucleotides in the coding strand of DNA, only the functions Cag and CcT correlate with OGT. The excess probabilities to find ApG and CpT pairs in the coding DNA are increasing significantly with OGT, correlation coefficient R = 0.68 and 0.601 (Fig. 2, upper row). Remarkably, the codon bias explains the observed sequence correlations in the coding parts of DNA. Eirst,... 

Fig. 1. A two-dimensional pulse sequence for separated-local-field spectroscopy. The pulse sequence correlates the chemical shift of a low-sensitive nuclei S (e.g., or with the dipolar coupling between S and the abundant nuclei I (e.g., or F). During the delays before (r—q) and after (t) the 7t-pulse, / spins are decoupled from S spins by continuous rf irradiation on S spins. The details of this pulse sequence are discussed in the text.

The extreme action effects of structures are caused by service and chmate loads and may be modeled as intermittent rectangular renewal pulse processes. Therefore, it is e q)edient to treat the safety margin of particular members as a random sequence. The revised values of instantaneous survival probabihty of particular members may be analyzed by the concepts of truncated probabihty distribution and Bayes theorem. The presented new design methodology based on conventional resistances, rank sequences, correlation factors and transformed conditional probabihties may be successfully used in the prediction of long-term survival probabilities of members and their systems during residual service Ufe. 

Figure 4 shows that the accumulation of counterions near macroions is much more prominent in Systems II and III as compared to the other two systems. The counterion densities at contact pigMi(l M) ire 0.021, 7.0, 9.2, and 0.151 j for Systems I-IV, respectively. Hence, the systems can be ordered with increasing density at contact according to I < IV < II < III, the sequence correlating excellently with the displacement analysis. Hence, this density analysis supports the view that the rejection of the macroion trial displacement originates from the large amoimt of nearby counterions. 

Finally, it is worth mentioning that in the rich behavior of copolymers at selective liquid-liquid interfaces we have not included results pertaining to random copolymers, where the range of sequence correlations plays a role similar to that...
