Domain single

The present chapter has no ambition to cover all these topics. We focus solely on the information content of the two-pathway coherent control approach, where the energy-domain, single quantum states approach to the control problem simplifies the phase information and allows analysis at the most fundamental level. We regret having to limit the scope of this chapter and thus exclude much of the relevant literature. We hope, however, that this contribution will entice the reader to explore related literature of relevance. 

PTKs are monomeric in the active form, and consist of an extracellular binding domain, single membrane-associated a-helix and cytosolic domain with the kinase activity. Ligand binding induces dimerization and autophosphorylation that enables binding to adaptor molecules. These molecules connect the receptor to the signal transmitting biopolymers.

The hysteresis loop of a single-domain single crystal of BaTiCF is shown in Fig. 2.46(a). The almost vertical portions of the loop are due to the reversal of the spontaneous polarization as reverse 180° domains nucleate and grow. The almost horizontal portions represent saturated states in which the crystal is single domain with a permittivity er of 160 (see Fig. 2.40(d)) measured in the polar direction. The coercive field at room temperature when the loop is developed by a 50Hz supply is 0.1 MVm-1 and the saturation polarization is 0.27 Cm-2. For fields in the approximate range 10 to 100 V mm 1 the hysteresis loop takes the form of a narrow ellipse, a Rayleigh loop, with its major axis parallel to the almost horizontal part of the fully developed loop.

It should be noted that a poling process is often necessary with single-crystal ferroelectric bodies because they contain a multiplicity of randomly oriented domains. There is therefore a sequence of states of increasing orderliness polycrystalline ferroelectric ceramics, poled ferroelectric ceramics, single-crystal ferroelectrics and single-domain single crystals. 

The heparan, chondroitin and hyaluronan synthetases, although one polypeptide chain, have two active sites corresponding to the two glycosyl transfers catalysed. Kinetic studies are technically very difficult, but the point was established in the case of the hyalurononan and chondroitin synthetases by the construction of chimeric proteins. Pasteurella multocida produces both chondroitin and hyaluronan by the action of two-domain single polypeptide synthetases. The chimeric protein from the N-terminal half of the hyaluronan synthetase and the C-terminal half of the chondroitin synthetase produced only...

For the description of the physical structure of the PET yarns, use is made of the two-phase model as depicted in Fig. 1. In that model, well-ordered crystalline regions alternate with less-ordered amorphous domains. Single...
