The statistical analysis showed interaction between the factors; therefore, the treatments selection was performed using the interaction plots (see Additional file 1: Annex S1).
To the internal validity, we define different designs to evaluate separately the factors, therefore, it is not possible analyze the interaction between the number of joins and branches, for example.
Also due to the smaller beam size, interference is not the dominant factor therefore the linear R-ZF precoding performs almost as well as DPC precoding.
HRV was mostly correlated with the stress factor; therefore, SVI (SVI, ratio of LF to HF), NN-50, and mean RR interval were considered to identify the most significant effect of SKY on stress (Figs. 4, 5, 6).
A large part of developmental genes consists of the transcription factor; therefore, it is also reasonable that a category related to transcription factor such as "mRNA transcription regulation" is overrepresented in hypermethylated genes.
Note that we focus on the inner problem, where the traffic is the most restrictive factor, therefore, in this case.
The cancer slope factor, therefore, aims to limit the number of expected cancers in the exposed population to no more than 1 in 1 million people.
Only a few studies included physical environment and practice related factors and the effect of these factors therefore remains unclear.
It is unclear why CDR, IDR, and EDR did not load on a single factor; therefore, the extracted three-factor model had unexpected factor loadings.
