G folding

To explain the vanishing integral nile we first have to explain how we detennine the synnnetry of a product. G fold degenerate state of energy and synnnetry T, with eigenfunctions - / -fold degen... 

If the gn roots are all different, then in first order the g -fold degenerate unperturbed eigenvalue Ef is split into g different perturbed eigenvalues. In this case, the degeneracy is removed in first order by the perturbation. We...

Fig. 5.20 Calculated lamellar spacings for copolymers with (/,g)-folded PEO and PBO blocks (loo) divided by measured lamellar spacings (d) and plotted against lm (Mai et al. 1997). Crystallization conditions are indicated by ( ) cooled at 10°Cmin T (o) quenched (a) annealed ( ) self-seeded. The symbol (v) denotes results from Yang et al. (1995). The dashed lines indicate the integral values of la)/d expected for the conformations with...

In addition, the functions q, if define what is called a g,-fold subspace of total Hilbert space. Furthermore, the eigenfunctions of two states with different values of q must be orthogonal since X is a Hermitian operator. Once again we normalise these functions to unity so that (7.4) may be generalised to...

A small fraction of histone H2A undergoes phosphorylation and dephosphorylation continuously, but HI and H3 are phosphorylated and dephosphor-ylated at specific stages of the cell cycle. Phosphorylation of HI has been thought essential for "condensation" of chromatin, H5 g folding into the tightly...

In the same general context, one can say that the eigen-value a is g-fold degenerate if there exist exactly g - linear independent eigen-fiinctions, i.e., having the closure property... 

Symmetry information can be obtained if the characters of the state vector with respect to the symmetry operations of the group are found. For F, being the first of a g,-fold set of degenerate states, this can be achieved by evaluating... 

When using a primary 3D interpretation technique, navigation should be performed in both directions to maximise polyp detection unless the image is represented in such a way that the eye can observe behind obstacles (e.g. folds) as is the case with the virtual dissection or unfolded cube techniques that will be discussed in the next Chapters 19 and 20. The 3D method may be more accurate than 2D interpretation, especially for smaller lesions, but it is more time-consuming (Dachman et al. 1998 Macari et al. 2000 Rex et al. 1999). 

Consider now T = K3. Since the attached path is sufficiently long, we see that the complex Horn K3, G) is actually isomorphic to Horn K3, K ). Also taking T = G5, we see that the 5-cycle cannot wrap around the attached path, and that in fact, Horn (G5, G) is isomorphic to Horn (G5, G ), where G is obtained from by attaching two edges one edge to 0 and one to / - - 1. Since the graph G folds to the graph A4, we may conclude by Theorem 18.22 that Horn Cz,G) Horn (G5, Ki). 

To start with, notice that G folds to a triangle simply fold the vertices di, d2, ds, then ci, C2, C3, and finally 61,62,63. This means that Horn (G5, G ) Horn (G5,1 3) in particular, it has two connected components, indexed by the directions in which the 5-cycle wraps around the 3-cycle. One direct way to see this winding direction is as follows map G to a triangle with vertices xi,X2,X3 by taking Oj, 6j, c, and d to a , for i = 1,2,3. This associates a map from G5 to to each map from G5 to G hence the corresponding winding direction is well-defined. 

If a suspicious area is detected when using a primary 2D review method, a 3D snapshot can be used to obtain more information about the nature of the abnormality (e.g. folds and ileocecal valves) (Figs. 9.8 and 9.9).
