Fundamental domain

The identification of the crystalline thickness may be possible from the result of the fit. As a frequent result of a model fit, the relative standard deviations of the fundamental domain thickness distributions, G /d and differ considerably.

Five fundamental domain structures are possible for block copolymers consisting of two types of blocks. Generally lamellar structures will form at compositions with approximately equal proportions of the two components. As the proportion of one component increases at the expense of the other, cylindrical morphologies will result. The matrix phase will... 

The identification of the crystalline thickness may be possible from the result of the fit. As a frequent result of a model fit, the relative standard deviations of the fundamental domain thickness distributions, Ci/r/i and 02/ 2, differ considerably. In many cases the broader distribution can be attributed to the amorphous (or soft) phase. Even higher significance of the assignment can be achieved if the material is studied in time-resolved SAXS experiments during processing (under thermal load, mechanical load). Thus it is not always necessary to resort to secondary methods" in order to resolve the ambiguity inherent to Babinet s theorem. 

The form factor is, in fact, an envelope, because it Umits the visibility of the reflections Outside the region where it has decayed to virtually 0, no scattering is observed. Sometimes the envelope is visible We see the spherical, the cylindrical or the layer shape of the fundamental domains in the oriented material.

We choose a Voronoi cell V as a fundamental domain of D. When one hits a three-dimensional boundary of a Voronoi cell, by cutting Eg parallel to the observable space, one projects into the observable space E the dual (three-dimensional) boundary. The result appears as a tile in E. The dual boundary is defined as a convex hull of all lattice points of which Voronoi domains contain the hit boundary. Instead of cutting the six-dimensional Voronoi cells, one can define a procedure on a single projected Voronoi cell y(0) with a hierarchy of all its lower-dimensional boundaries into the orthogonal space E, Vx(0) = W, the window [6]. In case of Z)g, the window W has an outer shape of a triacontahedron see Figure 12-2 top).

Carr-Helfrich one in nematics and may be studied quantitatively theoretically [280]. At high frequencies, an instability is observed with a characteristic frequency dependence of the threshold field Elayer thickness (fundamental domains). This has been regarded as an analog of the dielectric regime [282], but it can also be interpreted as the electrolytic mode [283] with some specific features. In some special cases a new domain mode is observed [284], which has been referred to the inertial (anisotropic) mode (discussed in Section 9.4.1.3 of this Chapter).

The fundamental unit of tertiary structure is the domain. A domain is defined as a polypeptide chain or a part of a polypeptide chain that can fold independently into a stable tertiary structure. Domains are also units of function. Often, the different domains of a protein are associated with different functions. For example, in the lambda repressor protein, discussed in Chapter 8, one domain at the N-terminus of the polypeptide chain binds DNA, while a second domain at the C-terminus contains a site necessary for the dimerization of two polypeptide chains to form the dimeric repressor molecule. 

IToteins may comprise a single domain or as many as several dozen domains (Figure 2.19). There is no fundamental structural distinction... 

Polypeptide chains are folded into one or several discrete units, domains, which are the fundamental functional and three-dimensional structural units. The cores of domains are built up from combinations of small motifs of secondary structure, such as a-loop-a, P-loop-p, or p-a-p motifs. Domains are classified into three main structural groups a structures, where the core is built up exclusively from a helices p structures, which comprise antiparallel p sheets and a/p structures, where combinations of p-a-P motifs form a predominantly parallel p sheet surrounded by a helices. 

The enormous increase in the number of groups working in this domain, in concert with the advances in the fundamental techniques of chromatography and laboratory automation (screening technologies) have led to the rapid and unprecedented accumulation of data [1]. 

Quantum Cellular Automata (QCA) in order to address the possibly very fundamental role CA-like dynamics may play in the microphysical domain, some form of quantum dynamical generalization to the basic rule structure must be considered. One way to do this is to replace the usual time evolution of what may now be called classical site values ct, by unitary transitions between fe-component complex probability- amplitude states, ct > - defined in sncli a way as to permit superposition of states. As is standard in quantum mechanics, the absolute square of these amplitudes is then interpreted to give the probability of observing the corresponding classical value. Two indepcuidently defined models - both of which exhibit much of the typically quantum behavior observed in real systems are discussed in chapter 8.2,... 

How is physics, as it is currently practiced, deficient in its description of nature Certainly, as popularizations of physics frequently reniiiid us, theories such as Quantum Electrodynamics are successful to a reinarkiible degree in predicting the results of experiments. However, any reasonable measure of success requires that wc add the caveat, ...in the domain (or domains) for which the theory was developed. For example, classical Newtonian physics is perfectly correct in its description of slow-moving, macroscopic objects, but is fundamentally incorrect in its description of quantum and/or relativistic systems. 

Ribosomes are ancient ribonucleoprotein complexes that are the sites of protein synthesis in living cells. Their core structures and fundamental functional mechanisms have been conserved throughout the three domains of life bacteria, archaea and eukaryotes. All ribosomes are organized into two subunits that are defined by their apparent sedimentation coefficient, measured in Svedberg units (S). There is a general...
