Full-wave Nonlinear Inverse Scattering for Acoustic and Electromagnetic Breast Imaging.
(2012)
Acoustic and electromagnetic full-wave nonlinear inverse scattering techniques are explored in both theory and experiment with the ultimate aim of noninvasively mapping the material properties of the breast. There is ...
Exploring the Mechanics of Transcriptional Control through DNA Looping with Optical Tweezers.
(2010)
The interior of a cell is a crowded and constantly fluctuating environment, where DNA and other biomolecules are highly constrained and subject to various kinds of me-chanical forces. To unravel the role of mechanics in ...
Regulating Gene Expression Through DNA Mechanics: Tightly Looped DNA Represses Transcription.
(2010)
It is now widely accepted that the mechanical state of DNA can play a major role in regulating the activity of RNA polymerase (RNAP). Not only have the global levels of supercoiling been shown to regulate transcription, ...
Nonlinear Optical Enhancement from Aggregate and Ensemble Effects in Organic Systems.
(2011)
Organic optoelectronics provide several advantages over traditional Si based systems. These advantages are typically cost, ease of manufacturing, and environmental impact. One area of particular interest in the field of ...
Plume-Surface Interactions due to Spacecraft Landings and The Discovery of Water on Mars.
(2010)
Pulsed supersonic jets or rocket plumes have different surface flow physics than steady jets, in particular in tenuous atmospheres such as that of Mars where jets are collimated over large distances compared to their ...
