Abstract We study a scale-invariant extension of the standard model which can simultaneously explain dark matter and the hierarchy problem.In our set-up, we introduce a scalar and a spinor as two-component dark matter in addition to a scalon field as a mediator.An interesting point about our model is that due to scale-invariant conditions, compared
Abstract Background Marine fishes have been shown to display low levels of genetic structuring and associated high levels of gene flow, suggesting shallow evolutionary trajectories and, possibly, limited or lacking adaptive divergence among local populations.We investigated variation in 98 gene-associated single nucleotide polymorphisms (SNPs) for
In the R22 (chlorodifuoromethane) steam-cracking process, which is used to produce a TFE (tetrafluoroethylene) monomer, distillation is employed to separate the high-purity TFE monomer from the cracked gas generated during this procedure.Traditionally, this distillation process is carried out using five towers.In this study, the traditional five-to
