High-intensity focused ultrasound (HIFU) has been used to ablate solid tumors and cancers. Because of the hypervascular structure tumor circulating blood inside it, interaction between HIFU burst vessel is a critical issue in clinical environment. Influences on lesion production potential rupture were investigated this study for efficiency safety ablation. An extracted porcine artery was embedd...

It is demonstrated that if cosmic dark energy behaves like a fluid with equation of state p = wρ (p and ρ being pressure and energy density respectively) as well as generalized Chaplygin gas simultaneously, Big Rip or Big Smash problem does not arise even for equation of state parameter w < −1. Unlike other phantom models, here, the scale factor for the future universe is found regular for all ...
