Pearson residuals

ANACONDA then calculates the value of the Pearson s chi-squared statistic and the adjusted Pearson residual values. Pearson s statistic represents a global measure of the difference between observed and expected codon frequencies (20).

The members of the protein kinase C family are central signal proteins and as such, are involved in the regulation of a multitude of cellular processes. A problem in the identification of substrates of protein kinase C is its low substrate specificity which often cannot be differentiated from that of protein kinase A, particularly in in vitro experiments. The consensus sequence of the phosphorylation sites in substrate proteins are similar to those of protein kinase A, in that basic amino acids are required in the neighborhood of the Ser/Thr residue to be phosphorylated. The following consensus sequences may be formulated for phosphorylation by protein kinase C ( = phosphorylation site) S /T XK/R K/RXXS /T K/RXXS /T XK/R K/RXS /T K/RXS /T XK/R (Pearson and Kemp, 1991).

Improved analytical capabilities have led to the analysis of several hundred xenoliths for osmium isotopic composition. The compatible nature of osmium during mantle melting means that, unlike incompatible-element-based isotope systems, peridotite residues have much higher osmium contents than mantle melts and thus the system is less readily disturbed by later metasomatism (see Section 2.05.2.5.3). This is clearly shown by rhenium and osmium abundances (Figure 21). The vast majority of rhenium contents of both cratonic and noncratonic peridotite xenoliths are below the PUM value proposed by Morgan et al (1981) and many are P-PGE depleted. This contrasts with almost universal TREE enrichment of whole-rock peridotites. That the Re-Os system is not immune from the effects of metasomatism is illustrated by the consideration of extended PGE patterns (Figure 20 Section 2.05.2.5.3 Pearson et al., 2002, 2004). Dismption of both rhenium and osmium in some mantle environments may have occurred (Chesley et al, 1999), especially where sulhde metasomatism is involved (Alard et al, 2000). However, Pearson et al. (2002, 2004) and Irvine et al (2003) have shown that coupled PGE and Re-Os isotope analyses can effectively assess the level of osmium isotope disturbance in peridotite suites. 

Figure 6.39. The results of Le Bail s full pattern decomposition of the powder diffraction pattern of Gd5Si4- The discrepancies between the observed and calculated profiles are small and all residuals are low, indicating that the unit cell dimensions are accurately determined and that the chosen peak shape function (Pearson-VII) is a good choice for this experiment. The observed data are available in the data files Ch6Exll MoKa.xy and Ch6Exll MoKa.dat on the CD.

Hence, we will continue the refinement and employ a different peak shape function. The use of the Pearson-VII function to represent peak shapes results in lower residuals (see rows 7 and 8 in Table 7.30). Nonetheless, individual isotropic parameters of Sil atoms remain unphysical and we may conclude that this is due to the low scattering power of Si and other errors present in the measured powder diffraction pattern. The errors were likely introduced during sample preparation, as it is easy to overlook...
