For this distribution the scale parameter is approximately the coefficient of variation. The shape parameter, \(\nu\), is modelled only with an intercept term. It was found that adding covariates to its linear predictor did not improve the adjustment. The functions \(f_{11}\) and \(f_{...
S2e,f. The coefficient of variation (CV) values for the control and YFY groups were both less than 0.1. The proportion of variation level between 10 and 20% accounted for the major part, demonstrating the high repetition in each group. The PCA results are shown in Supplementary Fig. S2g....
The coefficient of variation was below 5% for all the primer pairs used. Relative expression was calculated from the equation 2A−B/2C−D (where A is the cycle threshold [Ct] number for the gene of interest in the first control sample; B, the Ct number for the gene of interest in...
The extant literature commonly uses the value-added intellectual coefficient (VAIC) as a measure of IC, which includes an aggregate measure of the efficiency of employed capital (CEE), structural capital (SCE), and human capital (HCE). The presence of IC may be verified by the gap in the ...

The concentration of released p-nitrophenol was calculated accordingly to Beer Lambert law (A = εcl, where ε is the molar extinction coefficient of p-nitrophenol at 410 nm, c is the concentration and l is the optical path length in cm) as reported previously (83). A reaction mixture ...
Note that for changing the value of a specific coefficient, you should use matrix[idx1][idx2] = new_val and not a slice assignment. >>> Z = matrix([1,2,3,4],[5,6,7,8],[8,9,0,1],[2,3,4,5],[6,7,8,9]) >>> Z matrix( [1, 2, 3, 4], [5, 6, 7, 8], [...
The mammalian brain contains many specialized cells that develop from a thin sheet of neuroepithelial progenitor cells. Single-cell transcriptomics revealed hundreds of molecularly diverse cell types in the nervous system, but the lineage relationships b
we introduce the Gini coefficient formalism. The central panel of Fig.2shows the summed weights of the closestisatellites from the centre,\(\mathop{\sum }\limits_{j=1}^{i}{r}_{j}^{2}\), normalized by the total weight of all 11 satellites,\(\mathop{\sum }\limits_{j=1}^{11}{...
