Abstract We propose an amplitude-modulated pump ultrasound irradiation sequence to generate bubble cavitation for efficient sonoporation. By matching the envelope wavelength of modulated wave four times vessel diameter, we aimed improve efficiency collapse near wall and extend duration during repeated application sequence. Using agarose-based blood phantom, compared effects with those normal si...

This study investigates the effects of wall wettability on cavitation bubble collapse using pseudopotential lattice Boltzmann method with an appropriate external force term and contact angle boundary condition. The accuracy proposed numerical approach is verified by simulating a single-bubble near neutral wall. result shows that condition has significant effect forces exerted bubbles. For hydro...

When the Baltic States declared their independence in 1991, they did not become equal members of the international community in one day. Although the fall of the Berlin wall and the collapse of the Soviet Union declared the end to the Cold War, ideas, beliefs, prejudices and discourses were much harder to trigger. The study addresses the issues of newly independent states, establishing themselv...

Tracheary element differentiation requires strict coordination of secondary cell wall synthesis and programmed cell death (PCD) to produce a functional cell corpse. The execution of cell death involves an influx of Ca2+ into the cell and is manifested by rapid collapse of the large hydrolytic vacuole and cessation of cytoplasmic streaming. This precise means of effecting cell death is a prerequ...

The Rayleigh collapse time is the it would take to shrink an empty spherical bubble in infinite liquid domain zero size, which a function of ambient pressure and initial radius. If solid boundary located vicinity shrinking or collapsing bubble, then flow hindered, such that prolonged. This can be quantified with prolongation factor $k$ . Here, we provide for intermediate smallest wall stand-off...
