seismic waves travelling through inelastic media are attenuated by the conversion of elastic energy into heat. upon being attenuated, the travelling wave changes: amplitude is reduced, travelling waveform is modified due to high-frequency content absorption, and phase is delayed. attenuation is usually quantified through the quality factor q: the ratio between the energy stored and lost in each...

Abstract We developed the cosmological linear theory of perturbations for f ( Q,T ) gravity, which is an extension symmetric teleparallel with Q non-metricity and T trace stress-energy tensor. By considering ansatz = 1 )+ 2 ), has been broadly studied in literature coincident gauge where connection vanishes, we got equations consistent gravity when 0. In case tensor perturbations, propagation g...
