high‑intensity focused ultrasound (hifu) is a novel treatment modality used by scientists and clinicians in the recent decades. this modality has had a great and significant success as a noninvasive surgery technique applicable in tissue ablation therapy and cancer treatment. in this study, radio frequency (rf) ultrasound signals were acquired and registered in three stages of before, during, a...

Abstract We compute the power spectrum of curvature perturbations in stochastic inflation. This combines distribution first crossing times through end-of-inflation surface, which has been previously studied, with fields value at time when a given scale crosses out Hubble radius during inflation, we show how to compute. allows stochastic-? N formalism make concrete contact observations. As an ap...
