We analytically derive the propagating wavefront form of Swallowtail-Gauss beams (SGBs). and we demonstrate the propagation characteristics of SGBs experimentally and numerically. During propagation. one type of SGBs gradually evolves into a deformed SGBs. https://pvoantha62i9.timeblog.net/70682830/occurrence-of-anti-toxoplasma-gondii-antibody-and-evaluation-of-risk-infection-factors-in-goats-raised-in-sergipe-state-brazil
