Understanding canopy radiation regimes is critical to successfully modeling vegetation growth and function.
For instance, the vertical distribution of photosynthetically active radiation (PAR) affects vegetation growth,
informative upon carbon and energy cycling. Availing upon advances in information capture and computing
power, geometrically explicit modeling of forest structure becomes increasingly possible....
Several levels of eukaryotic chromatin structure have
been observed: the nucleosome, the 10 nm and 30 nm fibers
and loop domains, apparently attached to the nuclear
matrix. In this research, the structure and function of
chromatin at two of these levels was investigated, with
studies on both nucleosome positioning and...
Intensity beam profiles of a 633 nm laser off a super-polished glass surface were captured using surface polarization reflection. Profile capture can be difficult due to the relative intensities of molecular reflection versus macro reflection. Surface polarization reflection uses parallel polarized light incident at Brewster’s angle to extinguish macro reflection....
We investigated the potential use of airborne light detection and ranging (LiDAR) data to predict key wood fiber properties from extrinsic indicators in lodgepole pine leading forest stands located in the foothills of central Alberta, Canada. Six wood fiber attributes (wood density, cell perimeter, cell coarseness, mature fiber length, microfibril...
The Carnegie Ridge is a linear, aseismic, submarine ridge
lying between the Galapagos Islands and the coast of South America.
A 2300 meter deep saddle near 86°W. longitude divides the ridge into
western and eastern segments. Surface ship, near bottom, and grain
size studies from the saddle have been used...
Author Nella Larsen and photographer James VanDerZee are two of the most canonical figures of Harlem Renaissance studies, whose respective novels and portraits have been explored extensively, if separately, by scholars. Both Larsen's 1929 novel Passing and VanDerZee's studio portraiture of the 1920s and 1930s have been read in terms...
