A controlled variable is one which the researcher holds constant (controls) during an experiment. It is also known as aconstant variableor simply as a "control." The control variable is not part of an experiment itself—it is neither theindependentnordependent variable—but it is important becau...
In their final model, meaningful game was used as an exogenous variable associated with higher ratings on the eudaimonic-derived insight-construct, which in turn was the strongest predictor for appreciation. In the present study, respondents were not asked to name programmes they had found fun ...
Adherence was analyzed both as an absolute percentage and as a dichotomized variable (adherent vs nonadherent, with a 70% adherence cut-off). Predictors for adherence were identified using Gradient Boosting Machines and Random Forests (R package caret). Seventy percent of the observations were ...
Chirality plays an important role in science from enantiomeric separation in chemistry to chiral plasmonics in nanotechnology. However, the understanding of chirality amplification from chiral building blocks to ordered helical superstructures remains a challenge. Here, we demonstrate that topological defects,...
Logistic regression was implemented for the binary endpoint of DCR; Cox proportional hazards models were implemented for the time-to-event endpoints, PFS and OS; each model contained only one exposure variable, the group of treatment (experimental vs control treatment), and was weighted with SMRW...
The only demographic variable associated with completion rates was maternal education; higher maternal education correlated with higher completion rates across all groups (p = 0.013, OR = 2.61, 95% CI [1.12 6.58]). Further, completion was not associated with outcome variables at baseline ...
they are more likely to engage in physical activities such as sports, dancing and other physical activity programs outside of the school curriculum [16]. Trost et al. [12] found that in sixth grade children, physical activity self-efficacy was a key variable which distinguished the obese and...

An optimal control strategy of the variable damper to minimize the energy expenditure is proposed based on this walking model. In Section 3, orbital stability of this optimal control strategy is analyzed. Reduction in the energy expenditure and the peak load force exerting on the carrier are ...
However, in variable-sized networks, the number of packet arrival times can be extraordinarily large even within a short interval due to the bursty traffic nature. Although the authors in [3] have studied how to allocate a service curve in SCED under a variable-sized environment, they do not...
