Pascal s triangle

The intensities correspond to the coefficients of a binomial expansion (Pascal s triangle)... 

Patterns of this third class in fact demonstrate a complex form of scale-invariance by their self-similarity, in the infinite time limit, different magnifications observed at the same resolution are indistinguishable. The pattern generated by rule R90, for example, matches that of the successive lines in Pascal s triangle ai t) is given by the coefficient of in the expansion of (1 - - xY modulo-tv/o (see figure 3.2). 

There are two other important consequences of spin-spin coupling. First, n equivalent protons will split another signal into n + 1 lines (hence three methyl protons split a methylene CH2 into 3 + 1 = 4 lines). Second, the relative sizes of peaks of a coupled multiplet can be calculated from Pascal s triangle (Figure 1.5). 

Continuing in this way, the familiar sequence of numbers in Pascal s triangle emerges ... 

Something of scientific interest (among numerous other applications, Pascal s triangle is used to predict nuclear magnetic resonance [NMR] multiplet splitting patterns) has been created from the repeated application of a simple rule. 

In the example given above, the generation of Pascal s triangle has been brought to a halt once the nonzero values reached the outer limits of the small set of cells that are available. We cannot proceed farther until we decide what to do at these boundaries. (This is dealt with in section 6.5.)... 

For sets of spin- nuclei, the multiplet intensity ratios are simply the binomial coefficients found most easily from Pascal s triangle (Figure 2.11). 

Figure 2.11 Pascal s triangle for the determination of binomial coefficients.

Fig. 10.4. Illustration of Pascal s triangle only showing ratios to n — 6 according to M — (n+1) where M is the multiplicity and n is the number of scalar coupled nuclei. For example, a proton adjacent to three protons (n — 3) would appear as a quartet (M — 4) with relative peak intensities of 1 3 3 1.

Indeed solutions to several practical problems have been demonstrated, e.g., computation of Pascal s triangle modulo 2 [151], exclusive or (XOR) calculation using triple crossover [152] or string tiles [151]. Again, the annual conference Foundations of Nanoscience [143] provides a good review of the status of development of DNA computation by self assembly. Fig. 23 presents several AFM demonstrations of computation driven by DNA programmed self-assembly. 

A mathematical theorem defining the form of the polynomial corresponding to (a + b)", where n is a positive integer. The coefficients for each term of such a polynomial are given by Pascal s triangle. See Pascal s Triangle... 

The triangle can be generated by remembering three properties (a) the first row and first column are filled at every step with Ts (b) the second row and second column are sets of counting numbers (i.e., 1,2,3,.. . ) and (3) each of the remaining numbers is the sum of numbers to its left and above it. Shown here is Pascal s triangle for the first seven steps.

The number of lines expected and their relative intensities can be obtained from Pascal s triangle shown in Figure 8.9. 

We can see that the relative intensities of the outer lines in Pascal s triangle are always 1. and the intensities of the inner lines can be calculated by adding the two numbers diagonally to the left and right in the row above.
