We discuss Gosselin and Schyns’ (2003) reply to our criticisms and constructive suggestions concerning the bubbles method Murray and Gold (2003). We find that their reply does not mollify our concerns, and we still believe that reverse correlation will generally be preferable to the bubbles method until further developments (a) demonstrate more clearly what the bubbles method actually measures ...

Bubbling up: Dissolution of CO(2) bubbles in a suspension of colloidal particles chemically induces the assembly of particles on the surface of shrunken bubbles, and thus yields rapid continuous formation of a colloidal armor. This approach maintains the high colloidal stability of particles in bulk, has increased productivity, and allows the formation of bubbles with precisely controlled dimen...

We construct a model of rational bubbles under credit frictions and show that bubbles held by banks can generate large credit expansions followed by financial crisis. The size of boom-bust is somewhat larger than the case in which savers directly hold bubbles. Thus massive credit exansion during booms can be interpreted as an early warning indicator of possible subsequent crisis.

The interaction of gas bubbles with a vortex is investigated experimentally to clarify the role of the initial bubble position on its trajectory around the tip vortex shed from a large hydrofoil. The experiments performed with 4-6mm bubbles show that the bubbles can undergo no capture, quick capture into the tip vortex or slow capture with a spiral trajectory around the vortex.

The standard treatment of altitude decompression sickness (aDCS) caused by nitrogen bubble formation is oxygen breathing and recompression. However, micro air bubbles (containing 79% nitrogen), injected into adipose tissue, grow and stabilize at 25 kPa regardless of continued oxygen breathing and the tissue nitrogen pressure. To quantify the contribution of oxygen to bubble growth at altitude, ...

We extend our earlier work on cluster cores with distinct radio bubbles, adding more active bubbles, i.e. those with GHz radio emission, to our sample, and also investigating “ghost bubbles,” i.e. those without GHz radio emission. We have determined k, which is the ratio of the total particle energy to that of the electrons radiating between 10 MHz and 10 GHz. Constraints on the ages of the act...
