Male treefrogs produce loud and persistent acoustic signals called advertisement calls to attract mates. Ectothermic animals like frogs face an interesting challenge, in that temperature can significantly impact characteristics ...
Host proteins used in HIV assembly and budding
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Human immunodeficiency virus (HIV), the virus responsible for the AIDS pandemic, uses host cell machinery to assist its replication during the viral life cycle. A recent study randomly screened 21,000 host cell genes using ...
Natural variation in phenotypes associated with phototropins among geographically isolated populations of Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In Arabidopsis thaliana several phenotypes are controlled by blue light including chloroplast relocation movements and bending of the seedling stem in phototropism. These responses are controlled by the phototropins, phot1 ...
Electrohydrodynamic conduction pump - An experimental investigation [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Electrohydrodynamic pumps (EHD) were built and tested to further understand the nature of the technology. Two pumps built used a conductive pumping action to achieve flow within a dielectric fluid. The first pump (pump 11) ...
A hybrid MRI-based hippocampus segmentation algorithm
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We propose a new hippocampus segmentation method from MRI by integrating region-growing methods such as K-means clustering with PDE-based level set methods. Starting from a single point provided by the user, our algorithm ...
The effects of even-aged cutting on density and pairing success of Worm-eating Warblers
