The fast boiling dynamics of superheated surface layers of bulk water cavitating under near-spinodal conditions during nanosecond CO2 laser heating pulses was studied using contact broad-band photoacoustic spectroscopy. Characteristic pressure-tension cycles recorded by an acoustic transducer at different incident laser fluences represent (a) weak random oscillations of transient nanometer-size...

The diverse and often complex dynamics of digital flows in microfluidic networks is of much current interest to the microfluidic community due to the wide range of applications facilitated by such flows. In this paper, we highlight a counterintuitive phenomenon in the traffic of bubble trains. We show how all bubbles of a train can be sorted exclusively into one of the arms of a symmetric loop ...

LPPL models have been widely used to describe the behaviour of stock prices during an endogenous bubble and to predict the most probable time of the regime switching. Although their utility has been proved in many papers, there is still a lack of consensus on the statistical robustness, as the estimators are obtained through a nonlinear optimization algorithm and they are sensitive to the initi...

We show that static and oscillating photon bubbles can be excited by diffused light in the laser cooled matter confined in a magneto-optical trap. The bubble instability is due to the coupling between the radiation field and the mean field oscillations of the ultracold gas, and it can provide a source for low frequency turbulence. We consider a diffusion-dominated regime, which can be described...

We study the superconducting vortex states induced by the interplay of long-range Pearl repulsion and short-range intervortex attraction using Langevin dynamics simulations. We show that at low temperatures the vortices form an ordered Abrikosov lattice both in low and high fields. The vortices show distinctive modulated structures at intermediate fields depending on the effective intervortex a...

The theory of false vacuum decay in a thermal system may have cross-over from predominantly transitions to quantum as the temperature is decreased. New numerical methods and results are presented here that can be used model bubble nucleation this regime for cosmology laboratory analogues early universe phase transitions.

In the absence of coalescence, coarsening of emulsions (and foams) is controlled by molecular diffusion of the dispersed phase species from one emulsion droplet (or foam bubble) to another. Previous studies of dilute emulsions have shown how the osmotic pressure of a trapped species within droplets can overcome the Laplace pressure differences that drive coarsening, and " osmotically stabilise ...

purpose: to assess parameters that had a capability of influencing the rate of big bubble formation during deep anterior lamellar keratoplasty (dalk) in keratoconus. methods: a total of 290 consecutive eyes from 257 patients with keratoconus that underwent dalk using the big-bubble technique were enrolled. the influence of patient age and sex, family history of keratoconus, history of contact l...
