Computational studies of three chemical systems
(University of Missouri--Columbia, 2011)
is the study of pyrogallol[4]arene with R-groups R=H and R=phenyl. This macrocycle self-assembles into dimeric and hexameric nanocapsules. Several different structures for the macrocycle and its subunits, their relative energies, and their solvent interactions...
Establishing a foundation for large DNA transfer to artificial minichromosomes and B insert platforms in maize
(University of Missouri--Columbia, 2019)
In plants, conventional genetic engineering methods limit the number of available traits that could potentially improve the quality of agriculture. Agrobacterium-mediated transformation and biolistic bombardment are tools ...
Machine learning methods for 3D object classification and segmentation
(University of Missouri--Columbia, 2018)
