A calibration curve was obtained by plotting the response (peak area) versus concentration of drug and represented in Figure 3.
The linearity of the response of the detector for each drug was determined by plotting the response ratio (ratio of the peak area of the drug to that of the internal standard) versus the drug concentration and calculating the corresponding regression equation.
The plots were generated by plotting the response on the z-axis against two independent variables, ethanol concentration (X1) and microwave power (X2), while keeping the other two independent variables [irradiation time (X3) and liquid-to-solid ratio (X4)] at their zero level.
The calibration curve was constructed by plotting the response factors (RF) of calibration standard solutions versus perchlorate concentrations.
First, we extracted frequency tuning curves for each voxel by plotting the response size (compared with baseline) to the different frequency conditions.
The 3D response surface was obtained by plotting the response values (mg glucose/g dry substrate) on the Z axis against (1) the variables temperature and time, keeping the pH constant at its level 0), (2) the variables pH and time, keeping the temperature constant at its level 0), and (3) the variables temperature and pH, keeping the time constant at its level 0).
In order to determine the optimal levels of each variable for maximum protease production, three-dimensional response surface plots were constructed by plotting the response (protease production) on the z-axis against any two independent variables, while maintaining other variables at their central levels.
By plotting the response probability and 6-month survival according to IL8T1 (and by adjusting for the fixed – median – value of IL8T0 at 67 pg ml−1), it turned out that a threshold of 80 pg ml−1 might be a reasonable cut-off value for prognostic discrimination; in particular, patients below the threshold show a relatively favourable prognosis for both outcomes.
Concentrations of samples, including the QCB, are calculated from a calibration curve constructed by plotting the instrument response of analytical standards versus their known concentrations after automatically subtracting the y-intercept the instrument response at a zero concentration—from the response of the samples (Tay-intercept the
We illustrate this process leading to amplification by plotting the resonator response for input fields α in with slightly varying amplitude and phase.
