NSBP/NSHP Conference Proceedings:
Chaos in Geophysical Fluid Dynamics
Synchronization occurs ubiquitously in regular and chaotic oscillators. In geophysical fluid models, synchronization at one length or time scale can affect dynamics at all scales. Synchronicity as an organizing principle in nature, as an alternative to causality, has deep philosophical implications.

Poroelastic nanoindentation responses of hydrated bone 
Poroelastic analysis—a mechanical theory incorporating fluid motion through a porous elastic network—is used to examine spherical indentation creep responses of hydrated bone. Immersion of bone in polar solvents with decreasing polarity results in increased stiffness, decreased Poisson’s ratio, and decreased hydraulic permeability.

Topology and Predictability of El Niño and La Niña Networks
Analysis of the surface temperature fields for El Niño and for La Niña years shows that the El Niño network possesses significantly fewer links, a lower clustering coefficient and characteristic path length than the La Niña network, which indicates that the former network is less communicative and less stable than the latter. Because of this, the predictability of temperature decreases during El Niño years.

Acoustic Cavitation for Medical Applications
Ultrasound imaging is an important tool in medical physics, and cavitation, where the sound energy induces vaporization, often plays an important in the application of ultrasound therapy. Emulsions of superheated liquid perfluorocarbon droplets that are enclosed by albumin shells may prove especially useful in cancer therapy.

Self-Assembled Quantum Dots
Semiconductor structures that confine charge carriers on a length scale comparable to their de Broglie wavelength, or quantum dots, have been used in many applications including medical imaging, photovotaics, and diode lasers. They may one day be used as qubits in quantum computers. These structures often have stunning optical properties.
