For cancer to metastasize, tumor cells must invade the local tissue and grow and proliferate once they arrive. Tumor cell heterogeneity, the presence of multiple types of cancer cells within a tumor, can increase cell proliferation and invasion through interactions, increasing the potential for metastasis....

PIV uncertainty quantification is important for comparison with CFD simulations and engineering design, but is challenging due to the complex non-linear measurement chain which involves a large number of parameters. Multiple assessments show that none of the current methods can reliably predict the actual uncertainty...

Background-Oriented Schlieren (BOS) is used to measure fluid density from the apparent distortion of a target dot pattern. Here, we propose a new displacement estimation methodology based on tracking individual dots on the pattern as opposed to conventional cross-correlation algorithms. As dot patterns used in...

Measurement of pressure in a fluid flow is essential in engineering applications as well as in investigations of flow physics. Pressure measurement devices such as wall pressure ports, static tubes, pressure-sensitive paint, etc., can be invasive, and provide only point measurements or a surface distribution....
