Recent astrophsyical observations indicate that about 23% of the matter in the universe exists as non-luminous, non-baryonic dark matter. General thermodynamic arguments suggest that if …
Bone anchored prosthetic attachments, like other percutaneous devices, suffer from poor soft tissue integration, seen as chronic inflammation, infection, epithelial downgrowth and regression. We looked …
The relationship between alcohol and emotion is extremely complex. Prolonged heavy alcohol consumption and acute alcohol administration both affect emotional processing in the brain. In …
This dissertation, a social and cultural history of media and education in postwar Philadelphia, examines the concurrent struggles against racial discrimination on American Bandstand and …
An experimental study of electric field induced surface diffusion is presented. A FEM analysis and a stability analysis of conducting surfaces subjected to a normal …
This thesis presents the techniques we have developed in analyzing brain signals obtained from the most commonly used brain imaging methods, e.g., EEG/MEG and fMRI …
Generations of archaeologists have identified and examined craft production, specialization, and technological development as defining characteristics of sociopolitical complexity. Yet, the significance of North American …
Studies of two nanoscale systems with important engineering applications, Al-Si nanocomposites and Au nanoasperities, are investigated using molecular dynamics. The first system is studied in …
Traumatic injury to the spinal cord often results in irreversible loss of function as the central nervous system fails to spontaneously regenerate. The application of …
Maximum likelihood estimators have traditionally dominated discrete inference for a long time. In this work we apply statistical decision theory to derive a new contender …
Trypanosomes are the causative agent of human African sleeping sickness and nagana in cattle. The bovine parasite, Trypanosoma brucei brucei (T. b. brucei), is unable …
This dissertation discusses two related clinical applications of visible regime diffuse reflectance spectroscopy as well as two new configurations of liquid crystal microspectrometer suitable in …
Continental climate experiences significant changes and severely affects human's life. Quantitative reconstruction of past continental climate changes is extremely important for understanding their mechanisms in …
I investigated factors that influence microbial diversity and composition and the consequences of this diversity for plant communities. First, I used cloning and sequencing of …
Pulsed gradient spin-echo (PGSE) diffusion NMR spectroscopy was designed to measure diffusion coefficients and deduce the hydrodynamic radii of molecules in solution. By incorporation of …
This dissertation investigates how communities and advocacy groups in Appalachia, Maine, and Alaska use biomonitoring to work toward environmental health and justice. Biological monitoring, or …
The dispossession of the Native American land base during the nineteenth and twentieth centuries is at once a well-recognized historical process and a process seldom …
Based upon archival research at the Bancroft Library, Stanford, Harvard and UCLA and oral histories conducted with several prominent booksellers on the West Coast, my …
This dissertation explores of various modes of musical activism within the Mount Pleasant neighborhood of Washington, D.C. Music is an important aspect of life in …
The problem of detecting changes in images taken by a stationary camera has been well studied and many algorithms now exist which perform robustly in …
