%A = [Latex]\frac{Area of Peak A X 100}{Total Areas of Peaks (A + B + C + D)}[/latex] Real Chromatogram Let us now look at the actual chromatogram printout of HPLC separation of a mixture of vitamins A and E in a food matrix and see what the chromatogram represents ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
To answer the first two research questions, the Wilcoxon signed-rank test was used as the data meets the three assumptions for this test. The third research question used a Spearman correlation matrix to investigate the relationship between all outcome variables for rest and gameplay. Significance ...
the eigenvalues represent the variance of the data in the direction of the eigenvectors. In the case of axis aligned error ellipses, i.e. when the covariance equals zero, the eigenvalues equal the variances of the covariance matrix and the eigenvectors are equal to the...
We can represent this prediction step with a matrix, FkFk:It takes every point in our original estimate and moves it to a new predicted location, which is where the system would move if that original estimate was the right one.Let’s apply this. How would we use a matrix to predict ...
which is created by lining the inside of the mold with precise layers of clay to represent the skin thickness. When the clay lay-up is completed, the surface of the clay is fiberglassed to create the foam-running core. After the clay is cleaned out, the foam-running core is bolted into...

by using a special GO2All mapping in the annotation packages. You won’t have one of those, so instead you will have to make one. AnnotationDbi provides some simple tools to represent your GO term to gene mappings so that this process will be easy. First you need to put your ...
This is the final equation in the article: f(x) = 0.25x^2 + x + 2. It is an equation for the parabola shown higher up. Which "x" are you trying to calculate? If you are trying to find the zeros for the function (that is find x when f(x) = 0), then that is simp...
tested three real–time PCR assays for the detection of Candida spp in non-neutropenic critically ill patients with candidaemia, showing excellent sensitivity (90.9%) and specificity (100%) [48]. Finally several recently introduced diagnostic tools include: (a) matrix- assisted laser desorption ioni...
