- Description:
- Constrained optimization problems are prevalent in all areas of science and engineering, and many well-known numerical methods have been developed to solve these problems. Yet, when there exists random quantities in the model under consideration, most of the deterministic methods are no longer effective. In this dissertation, we address parameter...

- Description:
- Current prediction instruments for violent recidivism lack accuracy as recidivism rates for violent offenses remain high (Fazel & Wolf, 2015). Part of the issue may be the conceptualization of violent offenders as a homogenous group as opposed to heterogeneous subgroups. Additionally, various studies suggest that cognitive abilities in violent offenders...

- Description:
- The three-dimensional (3D) nanoscale structure of III-As nanowires is correlated with optical and electronic property measurements to deconvolve the contributions of strain, composition, and crystal structure to characteristics of interest for future electronic and optoelectronic devices. Multiple advanced two-dimensional (2D) and 3D characterization techniques are employed such as atom probe...

- Description:
- In nature, materials with complex architectures are formed through hierarchical self-assembly. Therefore, the study and design of hierarchically assembling materials is important in producing materials that mimic biological structures and is a key challenge in biomaterials science and engineering. In articular cartilage, hierarchical assembly of extracellular matrix (ECM) components provides...

- Description:
- Mitochondria-derived reactive oxygen species (mROS) are required for the survival, proliferation, and metastasis of cancer cells. The mechanism by which mitochondrial metabolism regulates mROS levels to support cancer cells is not fully understood. To address this, we conducted a metabolism-focused CRISPR/Cas9 genetic screen and uncovered that loss of genes encoding...

- As demonstrated by efforts in graphene commercialization, scalable synthesis and high-quality material availability are primary limiting factors for the realization of technologies based on two-dimensional (2D) materials. Thus, in considering the fate of emergent 2D materials such as the metal chalcogenides, the challenge of scalable synthesis is a highly relevant...

- Description:
- Many theories of categorization have included an intuitive role for our ability to detect and judge similarity. Yet, this important role of similarity processing has been disputed. This research adopts a model of similarity processing through structure mapping (Gentner, 1983) to explore its role in similarity processing and categorization. Relational...

- Carbonates constitute Earth's largest carbon (C) reservoir, with most shallow marine deposition occurring on the low-latitude carbonate platforms covering ~800,000 km2. The Yucatán Platform situated between the Western Caribbean and Gulf of Mexico basins, is one of the largest present-day carbonate platforms. As with post-Paleozoic carbonates generally, it is readily...
