• The Effect of Acute Exercise and Latent Cytomegalovirus Infection on Nk-Cell Redeployment and Anti-Tumor Cytotoxicity in Healthy Adults ﻿

Allogeneic adoptive transfer of NK-cells from healthy donors to cancer patients has shown promise as a means of controlling or reversing the spread of multiple human malignancies including multiple myeloma and acute myeloid ...
• The Geometry of Structured Parseval Frames and Frame Potentials ﻿

(2015-05-06)
In this dissertation, we study the geometric character of structured Parseval frames, which are families of vectors that provide perfect Hilbert space reconstruction. Equiangular Parseval frames (EPFs) satisfy that the ...
• Exploration of Possible Enhancement of Superconductivity by Interface, Doping, and Pressure Effects ﻿

(2015-12-09)
The superconductivity in CaFe2As2, both at ambient and elevated pressures, remains an open question. Both interface-associated superconductivity and spontaneous phase separation (producing a new phase at low temperature) ...

(2015-12-03)
In this dissertation I developed or perfected unobtrusive methods to quantify sympathetic arousals. Furthermore, I used these methods to study the sympathetic system's role on critical activities, arriving at intriguing ...
• Evaluation of the Best Equation of State for Enhanced Oil Recovery Use in Ultra-high Pressure Hydraulic Calculation ﻿

(2015-05-19)
Enhanced oil recovery (EOR), is an essential part of oil and gas production nowadays. Gases used include carbon dioxide (CO2), natural gas, or nitrogen (N2). The discharge pressure of the platform injection compressor ...
• The Effects of Treadmill Exercise in the P301S Mouse Model of Tau Pathology ﻿

(2015-09-11)
Tauopathies are a group of neurodegenerative disorders characterized by severe cognitive and motor deficits that are associated with the development of neurofibrillary tangles (NFTs), intracellular protein aggregates ...
• Disruption of Gravin’s Scaffolding Protects against Isoproterenol Induced Heart Failure in Mice ﻿

(2015-09-11)
Impairment in the β adrenergic pathway is one of the hallmark pathologies of heart failure. This vicious cycle starts with chronic stimulation of the βARs during heart failure causing their severe desensitization and down ...
• A New Gap Theorem Result for Proper Holomorphic Mappings Between Complex Balls ﻿

(2014-05-02)
In this dissertation, we study how rigidity properties of proper holomorphic mappings from complex balls of dimension $n$ to complex balls of dimension $N$ allow us to classify all such maps for particular values of $n$ ...
• Mechanistic Study and Ligand Optimization of the Copper(I)-Catalyzed Azide-Alkyne Cycloaddition (CuAAC) Reaction ﻿

(2016-12-05)
The copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction is a prime example of “click reaction” that has been widely applied in diverse fields. The mechanism of this reaction has been proposed involving di-copper ...
• Analytical and Numerical Modeling of Mechanical Cleaning Device (MCD) for High Angle Wells ﻿

(2016-12-13)
Drilling subs, having helical grooves or blades on their surface, assist in cuttings bed removal by creating turbulence and bringing the cuttings into suspension for removal by the drilling mud. Several of these subs, ...
• The Importance of Transition-A Descriptive Study of Eligibility Assessment Requirements at the Postsecondary Level for Tier One and Community Colleges in Texas: A Bridge Over Troubled Waters ﻿

(2016-12-08)
Transition from high school to a postsecondary endeavor is an important and often trying time for students who want to pursue their postsecondary education (Cleary, Walter, & Jackson, 2011; Venezia & Jaeger, 2013). A ...
