The Editors have retracted this Article.
After publication, serious concerns were identified regarding the scientific validity of the theoretical models presented in the Article. Several equations presented in the manuscript are mathematically incorrect, incomplete, or contain placeholder terms, rendering the described model ill‑defined and non‑reproducible. As a result, the theoretical basis of the study cannot be validated. The Editors therefore no longer have confidence in the research presented in this work.
Shimeles Getahun has not explicitly stated whether they agree or disagree with this retraction.
