- Description:
- The basal ganglia operate largely in closed parallel loops, including an associative circuit for goal-directed behavior originating from the dorsomedial striatum (DMS) and a somatosensory circuit important for habit formation originating from the dorsolateral striatum (DLS). An exception to this parallel circuit organization was proposed to explain how information is...

- Description:
- This dissertation project explores the relationship between the architectures of black masculinity in America and a specific performance of discreet sexual identity. Through critical ethnographic and discursive exploration, I look closely at a group of black men who describe themselves as being on the "down low" (DL). These men, who...

- Description:
- Complex oxides show great potential for future devices as they offer functionalities beyond what can be delivered by conventional semiconductors. Among the complex oxides, the ABO$_{3}$ perovskite oxides are the most studied and engineered in the form of thin films and heterostructures. This thesis applies powerful synchrotron-based X-ray characterization tools,...

- Description:
- In this dissertation, we start with the dictionary learning (DL) based single-frame super-resolution (SR) problem, where low resolution (LR) input frames are super-resolved to high resolution (HR) output frames. We propose to extend the previous single-frame SR methods to multiple-frames, i.e., estimating single HR output frame by multiple LR input...

Synthesis of Fluorescent DNA-Modified Polymer Nanoparticles for Use in a Highly Sensitive DNA Assay,
- Description:
- Polymer nanoparticles (PNPs) were formed from amphiphilic diblock copolymers consisting of a hydrophilic block with pendant polyethylene glycol tosylate (PEG-OTs) groups and a hydrophobic block with pendant terthiophene (TTT) groups. The resulting PNPs were characterized using dynamic light scattering (DLS) and transmission electron microscopy (TEM) to determine size, shape, and...

- Description:
- Recent discoveries of black hole (BH) candidates in galactic and extragalactic globular clusters (GCs) have ignited interest in understanding how BHs dynamically evolve in a GC and the number of BHs (NBH) that may still be retained by today's GCs. Numerical models show that even if stellar-mass BHs are retained...

- Description:
- Regulatory T (Treg) cells are required to control immune responses and maintain homeostasis, but are a significant barrier to antitumor immunity. Conversely, Treg instability, characterized by loss of the master transcription factor Foxp3 and acquisition of proinflammatory properties, can promote autoimmunity and/or facilitate more effective tumor immunity. A comprehensive understanding...

- In 2015, the United States Preventive Services Task Force (USPSTF) recommended targeted screening for prediabetes and diabetes (dysglycemia) in adults who are aged 40 to 70 y old and overweight or obese. Given increasing prevalence of dysglycemia at younger ages and lower body weight, particularly among racial/ethnic minorities, we sought...

- Transposable elements (TEs) have been recognized as potentially powerful drivers of genomic evolutionary change, but factors affecting their mobility and regulation remain poorly understood. Chaperones such as Hsp90 buffer environmental perturbations by regulating protein conformation, but are also part of the PIWI-interacting RNA pathway, which regulates genomic instability arising from...

- Description:
- Affective science has long been interested in the coherence between different emotion response systems (e.g., subjective emotional experience, behavior, physiology). Although evolutionary functionalist accounts of emotion hold that emotional coherence should be related to greater adaptation, few studies have analyzed links between emotional coherence and wellbeing. Thus, in this laboratory-based...
