Studying human spermotozoa motility is a subject of growingimportance due to human male subfertility and the fact that thein-vitro fertilisation interventions that bypass normal spermmotility are invasive and entail significant risk for thehealthy female partner, as well as being economicallyprohibitive for many. We present examples of how fluid...

Coherent light scattering by a disordered medium produces a speckle pattern whose statistical properties have been extensively studied. On the fundamental side, intensity fluctuations and correlations are basic ingredients in mesoscopic phenomena. On the applied side, they offer the possibility to design sensitive sensing and imaging techniques ...

This talk will present the methods and procedures used to produce the first image of a black hole from the computational Event Horizon Telescope. It has been theorized for decades that a black hole will leave a "shadow" on a background of hot gas. Taking a picture of this black hole shadow could help to address a number of important scientific q...

Optical coherence tomography (OCT) provides an alternative to physical sectioning that allows for imaging of living samples and even in vivo examination of cell structure and dynamics. There is, in the OCT community, a widely held belief that there exists a trade-off between transverse resolution and the thickness of the volume that may be image...

Over the last two decades, multiphoton microscopy has created a renaissance in the brain imaging community. It has changed how we visualize neurons by providing high-resolution, non-invasive imaging capability deep within intact brain tissue. Multiphoton imaging will likely play an essential role in understanding how the brain works at the level...

The subsurface is where most of the available freshwater is stored; in the United States, groundwater is the primary source of water for over 50 percent of Americans, and roughly 95 percent for those in rural areas. Cleaning up the surface from industrial and nuclear wastes is quite challenging. A major impediment in studying processes in the su...

The butterfly algorithm is a robust alternative to the FFT forcomputing certain oscillatory integrals in a fast and accurate manner. Inthis approach low-rank interactions are updated in a hierarchical fashionup and down quadtrees. We review the method, its expected accuracy, andpresent an application to synthetic aperture radar imaging. Joint wo...
