We discuss the space-time structure for the process of decay of a bubble of hypothetic phase – disoriented chiral condensate (DCC). The evolution of initial classical field configuration corresponding to the bubble of DCC is studied both numerically and analytically. The process of decay of this initial configuration depends crucially on selfinteraction of the pionic fields. It is shown that in...

A model for the theoretical description of oneand two-dimensional structure formation in bubble-liquid mixtures is developed. It consists of a coupled system of partial differential equations describing the spatiotemporal evolution of the sound field amplitude and the redistribution of bubbles in a liquid. A linear stability analysis of the ~unstable! uniform bubble distribution is presented. N...

We integrate air bubbles into conductive elastic composite-based stretchable conductors to make them mechanically less stiff and electrically more robust against physical deformations. A surfactant facilitates both the formation and maintenance of air bubbles inside the elastic composites, leading to a simple fabrication of bubble-entrapped stretchable conductors. Based on the unique bubble-ent...

This paper deals with the two-state (opening-closing of base pairs) model used to describe the fluctuation dynamics of a single bubble formation. We present an exact solution for the discrete and finite size version of the model that includes end effects and derive analytic expressions of the correlation function, survival probability, and lifetimes for the bubble relaxation dynamics. It is sho...

Cavitation bubbles were generated by the 193 nm argon fluoride excimer laser delivered with a specially designed tip into absorbing NaCl solution. The dynamics of bubble formation and collapse have been studied using fast flash photomicrography. The bubble dimensions were measured at different time delays as a function of the tip exit diameter, the energy fluence of the laser, and the NaCl conc...

Measurements of space and time resolved subcooled pool boiling of FC-72 in low, earth, and high gravity environments were made using a microscale heater array. Data from each heater in the array were synchronized with highspeed digital video. The boiling behavior was dominated by the formation of a large primary bubble on the surface which acted as a ‘‘sink’’ for many smaller bubbles surroundin...

In this work, the evolution of gas-filled cracks under gas implantation and subsequent annealing is studied on the basis of an elastic continuum approach. The observed growth limitation of He-filled nanocracks in SiC is attributed to their stabilization by the formation of circular dislocation dipoles. The formation and Ostwald ripening of bubble-loop complexes at elevated temperatures is model...

purpose: to compare visual outcomes after deep anterior lamellar keratoplasty (dalk) between eyes with and without successful big-bubble formation. methods: in this retrospective comparative study, a total of 290 consecutive eyes from 257 keratoconus-affected patients underwent dalk with the big-bubble technique were enrolled. in cases where the big bubble could not be accomplished, manual stro...

Interleaflet cavitation in lipid bilayer membranes, or, shortly, intramembrane cavitation (IMC), is the formation of gas bubbles between the two leaflets of the membrane. The present paper focuses on the thermodynamics of IMC, namely, on the minimum work required to form an intramembrane cavity. The minimum work can be separated into two parts, one that depends on the volume and number of gas m...

A two-dimensional air-fluidized bed of 600 mm width and 1000 mm height was studied to investigate the formation, rise and cracking process of a bubble. The particles were assumed to be regular round particles of diameter 4 mm. The RNG k-ε model was employed for the turbulence, and the time integration scheme is the first order implicit difference with the time-step 0.0001 s. The equations were ...
