Non-invasive Derivation of 3D Systolic Nonlinear Wall Stress in a Biventricular Model from Tagged MRI
We present a nonlinear finite element method to calculate the local myocardial wall stress in a reconstructed biventricular MRI model. Nonlinear formulations are utilized in order to describe the ventricular l...

Fabrication of a Nanoneedle Array
We have developed a new fabrication method for building large arrays of needles with nanometer-size apertures. Because the process is entirely based on standard photolithographic techniques and conventional si...
