This indica es ha he same disc e e-scaling symme y ound in cosmological pe u ba-

The analyses abo e, hough de i ed om e y di e en physical sys ems, bo h e eal he ap-

To make his connec ion explici , we de ine a mapping be ween he phenomenological

This cons uc ion is analogous o he ea men o disc e e scale in a iance in c i ical

The p esence o log-pe iodic co ec ions in bo h GR and SR can be ein e p e ed in e ms

como ing wa enumbe kin he scala sec o , he g a i a ional-wa e equency in he enso

The g adien o his po en ial yields an e ec i e accele a ion, wi h an addi ional ac o

This exp ession shows ha he log-pe iodic modula ions ac as a d i ing e m, oscilla o y in

Finally, he co esponding e ec i e o ce on a es pa icle o mass mis

The esul s p esen ed he e highligh h ee cen al poin s. Fi s , he e ec i e o ce iden i ied

Second, he amewo k p o ides a es able and alsi iable cons an , χ, de ined h ough

Finally, he log-pe iodic inge p in s canno be consis en ly emo ed o igno ed. To
