The design is composed of incomplete mixture blends with different levels of amounts except the centroid point as a complete mixture blend.
In order to obtain a distinct effect, the levels of amounts and delays were chosen in such a way as to ensure equal influence of both on the subjective value (SV) of the delayed reward according to the hyperbolic model: (Mazur, 1987), where A is the size of the amount, D is the length of the delay (in days), and k is an individual discounting parameter.
A mixture-amount experiment is a type of mixture experiment that is performed at two or more levels of total amount.
The resulting component-amount design in three components has the levels of amount A = 0.0375, 0.5125, 0.6708, 0.9875, and 0.7500 with replicates 1, 3, 3, 7, and 1 and is given in Table 10.
Each of these dimensions offers several levels of amount aggregation, along one hierarchy for the date and agency dimensions and along one of two possible hierarchies for the cars (hcars1 and hcars2) dimension.
The t-scores were higher for one type of institution and for high competence levels, but the slope of the curves was the same among stratified groups, for given levels of amount of clinical exposure.
As sex differences may reflect greater cigarette consumption in males, meta-analysis estimates of the sex ratio for ever/current smokers and for all lung cancer were also calculated within levels of amount smoked (as defined in section G).
PDE was maximum at highest level of drug/polymer ratio and mid-level of amount of polymer (Fig. 5a).
Lowest PS of about 175 nm was observed at −0.5 to 0 level of drug/polymer ratio, −0.8 to −1.0 level of amount of polymer at +1 level of volume of organic phase (Fig. 4a).
For sex, additional analyses were conducted for current and for ever smoking, for squamous and adeno, and also within level of amount smoked.
Extrapolating the functional significance of these findings, we examined the levels of Delta, amounts of active Notch and the efficiency of myogenic responses in human satellite cells cultured in the presence of agonists and antagonists of MAPK pathway.
