Southern voids : structure and cosmological implications
… of clusters and the void radii is found using a spherical collapse model for structure formation. The ratio of these two quantities is used to put constraints on the cosmic density parameter 0 and observational data indicate that the universe is open.

Functional Cylindrical Polymer Brushes and Their Hybrids with Inorganic Nanoparticles
… amount of mono-valent salt induced the collapse of these brushes. When di- and tri-valent counterions were added, helical transition morphologies were recorded before the brushes collapsed into sphere-like structures. Special trivalent counterions, which can change valency through …

Detailed simulations of bubble-cluster dynamics
The violent collapse of bubble clusters can be an important mechanism of damage to adjacent material surfaces in both engineering and biomedical applications. Because of their complexity, past theoretical studies have generally been restricted to significantly simplified models, such as homogenized …

The structure and evolution of dark matter halos and their implications for cosmology
This is a study of how the properties of dark matter halos can be used to probe fundamental questions in cosmology. Similar to the inner regions of a halo the outer density profiles of the dark matter halo carry a wealth of information regarding its formation epoch, accretion history and …
