Why are asset prices so much more volatile and so often detached from their fundamental values? Why does the bursting of …nancial bubbles depress the real economy? This paper addresses these questions by constructing an in…nite-horizon heterogeneous agent general equilibrium model with speculative bubbles. We characterize conditions under which storable goods, regardless of their intrinsic valu...

A deterministic trading strategy by a representative investor on a single market asset, which generates complex and realistic returns with its first four moments similar to the empirical values of European stock indices, is used to simulate the effects of financial regulation that either pricks bubbles, props up crashes, or both. The results suggest that regulation makes the market process appe...

The presented software application allows GUI-based access to the bubble dissolution model presented by McGinnis et al. [McGinnis, D.F., Greinert, J., Artemov, Y., Beaubien, S.E., Wüest, A., 2006. The fate of rising methane bubbles in stratified waters: what fraction reaches the atmosphere? Journal of Geophysical Research 111, C09007. doi:10.1029/2005JC003183]. It quantifies the dissolution of ...

Path instability of a rising bubble is complex phenomenon. In many industrial applications, bubbles encounter walls, and the interactions between wall have significant impact on flow physics. A single near vertical was experimentally observed to follow bouncing trajectory. To investigate near-wall dynamics bubbles, 3D numerical simulations were performed based volume fluid (VOF) method using op...

Ultrashort lasers are typically utilized for tissue dissection by sequential application of tightly focused beam along a scanning pattern. Each pulse creates a small (on the order of 1μm) zone of multiphoton ionization (optical breakdown). At energies exceeding vaporization threshold cavitation bubble is formed around the focal volume. A continuous cut is formed if the rupture zones produced by...

A micro-competition system is designed for simultaneous quantification of multiple glycans on intact cell surfaces, by integrating two-surface–one-molecule competition with surface enhanced Raman scattering (SERS). The micro-competition is achieved among multiple-polysaccharide-coated gold nanostars functionalized silica bubbles, target cells and gold nanoprobes at a micron scale. The gold nano...

[1] Methane is a strong greenhouse gas, and marine and wetland sediments constitute significant sources to the atmosphere. This flux is dominated by the release of bubbles, and quantitative prediction of this bubble flux has been elusive because of the lack of a mechanistic model. Our previous work has shown that sediments behave as elastic fracturing solids during bubble growth and rise. We no...
