Alternative assessment of machine learning to polynomial regression in response surface methodology for predicting decolorization efficiency in textile wastewater treatment.

This study investigated the potential of machine learning (ML) as a substitute for polynomial regression in conventional response surface methodology (RSM) for decolorizing textile wastewater via a UV/HO process.

Conception rate according to the size and location of corpus luteum and coexistent follicle before embryo transfer in Hanwoo.

The size and location of the corpus luteum and the presence of coexistent follicles are crucial factors in synchronizing recipients and determining the suitability for embryo transfer.
