Detection of Dense, Overlapping, Geometric Objects

Author(s)
Adele P. Peskin, Boris Wilthan, Michael P. Majurski
Using a unique data collection, we are able to study the detection of dense geometric objects in image data where object density, clarity, and size vary. The

Low-Field Magnetic Resonance Imaging of Roots in Intact Clayey and Silty Soils

Author(s)
George Bagnall, Cristine` Morgan, Matthew Rosen, Mark Conradi, Stephen Altobelli, Dean Kuethe, Haly Neely, Neha Koonjoo, Bo Zhu, Karl Stupic, John Mullet, Brock Weers, Eiichi Fukushima, William Rooney
The development of a robust method to non-invasively visualize root morphology in natural soils has been hampered by the opaque, physical, and structural

Mid-infrared frequency combs at 10 GHz

Author(s)
Abijith S. Kowligy, David Carlson, Daniel D. Hickstein, Henry R. Timmers, Alexander Lind, Scott Papp, Scott Diddams
We demonstrate 10 GHz mid-infrared frequency combs spanning 3-5 μm and 7-11 μm that are generated with few-cycle electro-optic pulses and intrapulse difference
