Nakatsuji and Yasuda [56, 57] derived the 3- and 4-RDM expansions, in analogy with the Green function perturbation expansion. In their treatment the error played the role of the perturbation term. The algorithm that they obtained for the 3-RDM was analogous to the VCP one, but the matrix was decomposed into two terms one where two A elements are coupled and a higher-order one. Neither of these two terms can be evaluated exactly thus, in a sense, the difference with the VCP is just formal. However, the structure of the linked term suggested a procedure to approximate the A error, as will be seen later on. 

At such low concentrations the lithium and boron are exposed homogenously to the neutron flux. Because of the large thermal-neutron cross sections for Ii and °B, these isotopes are depleted significantly during the typical fuel irradiation time of 4 years. Therefore, to calculate the tritium activity (iVX) - in a fuel element after an irradiation time, we rewrite Eq. (2.100), recognizing that the chain-linking term here is 0o instead of X. For the Li reaction of Eq. (8.47),... 

Coupling results of the Cl-like calculation (limited to linked terms) and the full EOM-CCSD one, Eq. (15), were compared for a large variety of couplings with different basis sets in order to establish the numerical importance of the quadratic term. The largest FC quadratic contribution was... 

T. It is the presence of exp(—7), rather than exp(T ), in Eq. (4.12) that gives rise to the exactly closed quartic equation for T, Moreover, the presence of the commutators in the expression for E and the fact that T contains only particle creation and hole annihilation operators makes the CC-calculated energy contain only linked terms (in the sense discussed in Chapter 3). This then makes contain only size-consistent terms. 

The minimal dressing of (SC) CAS-SDCI yields a size-extensive method deleting all unlinked terms in CAS-SDCI, but does not include any other linked term. One might cany out a full dressing including all pertinent linked terms. In such a case dressed-CAS-ST>Cl becomes equivalent to SS-MRCC. There is no natural way to turn ec-CCSD into SS-MRCC (except a formal correction using obtained from the SS-MRCC we attempt to mimic). 

Cross-linking is initiated by the formation of allysine and/or hydroxyallysine from specific Lys residues in the telopeptides of the interstitial collagens (Fig. 6). This step requires the action of the specific enzyme, lysyl oxidase. These aldehydes may then form initial bifunctional cross-links, termed reducible cross-links as they can be reduced by sodium borohydride. These are either aldol condensation products or aldimine or ketoamine links. The aldimine and ketoamine involve specific Lys or Hyl residues either from the telopeptides or from the helical domain of the collagen. The sites of these specific residues have been determined (Fig. 6) (50).
