Next, we need to find the coefficient of xn in (1+x)101 and combine it with the coefficients from the expansion of (1−x+x2)100. 1. The expansion of (1+x)101 gives: 101∑m=0(101m)xm The coefficient of xm is (101m). 2. Now we need to find the coefficient of xn−m ...
Typically, the effects of single-sex schooling are small at best, and tend to be statistically non-significant once pre-existing differences are taken into account. However, researchers often have had to rely on observational studies based on small non-representative samples and have not used more...
Peaks with intensity levels in blanks exceeding 0.1 of the intensity levels in real samples were excluded; peaks with the coefficient of variation in QC samples above 25% were excluded; peaks with the correlation coefficient between the DiQC series below 0.9 were excluded. Out of 341 transitions,...
is known as a coefficient of the noise function and \(f'_{t} = \alpha f_{t}\) for all \(t \in \{0, \dots , \lambda \}\). Similar can be applied to \(Q(\cdot )\) with Gaussian elimination from top to bottom, yielding equation of the form \...
We remeasured samples with a coefficient of variation (CV) > 7% between duplicates. Moreover, we reran any microtiter plate for which the intra-assay CV of the internal high- and low-value quality controls exceeded 10%. For the samples analyzed at both IPB and DPZ, the intra-assay CVs...

“low-temperature” annealing at <350 ∘C is usually used, but this necessitates developing custom outgassing techniques and direct bonding recipes that require extensive resources to improve yield. Mismatches in the coefficient of thermal expansion (CTE) must also be minimized. Surface topography...
