Entangled photons serve as an important tool in the field of quantum information processing. Traditionally, spontaneous parametric down-conversion (SPDC) in second-order nonlinear crystals has been the workhorse source for generating entangled photons. However, those SPDC-generated photons are notoriously difficult to couple into single-mode optical fibers due to mode mismatch, thus...
This dissertation presents a Nuclear Magnetic Resonance (NMR) study of anisotropic superconductors, MgB$_2$ and Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ (Bi2212), and diffusion in glass-forming aqueous solutions of glycerol. In glycerol and deuterated water mixtures, the diffusion of glycerol is measured selectively by the $^1$H NMR stimulated echo technique in the gradient field of a...
Magnetic resonance imaging (MRI) allows for the selective visualization of blood vessels via the intravascular injection of a paramagnetic contrast agent and the suppression of background signal. Called magnetic resonance angiography (MRA), this technique can produce three-dimensional images and is useful clinically for the noninvasive diagnosis of vascular disorders. In...
This final report contains information on years 6-7-8 (2004-2007) of TEA-21 funded projects designated A487, W420, and A212. The report was submitted by Morris E. Fine and Semyon Vaynman in 2007.
In Sub-Saharan Africa, epidemiological studies have reported an increasing burden of non-communicable diseases (NCD) among people living with HIV. NCD management can be feasibly integrated into HIV care; however, clinic readiness to provide NCD services in these settings should first be assessed and gaps in care identified. A cross-sectional survey...
The textbook proceeds with an introduction to theory and concept building, moves to an explanation of causal inference (how do we 'know' whether something is causal?), and then provides a quick introduction to data and hypothesis testing. Following that, each chapter is devoted to a particular research method used within...
Autism was originally described as involving an apparent lack of motivation for social interaction. Social motivation has not figured prominently in subsequent theorizing regarding this disorder. Instead, theory of mind deficits have taken center stage as a theory of autism. This is surprising because evidence of social motivation deficits appear...
This dissertation explores a seventy-year period of community growth and activism among African Americans in nineteenth-century Iowa, showing how citizenship was defined, contested, expanded and confined. Antebellum black migrants lived on the margins of a hostile society and struggled for equal citizenship using their labor, their community institutions, the legal...
A study of the optical properties and superconductivity in semiconductors is presented using the highly precise all-electron full-potential linearized augmented plane wave (FLAPW) density functional calculations.
Optical properties [$\varepsilon(\omega)$,$n(\omega)$,$k(\omega)$,$R(\omega)$ and $\alpha(\omega)$] of some III-V semiconductors [InAs, InSb, GaSb, and AlSb] and their critical point (CP) energies, are calculated from the...
