(2010-03-23)Department: PhysicsWe report the observation of coherent acoustic phonon oscillations in GaSb(20 nm)/GaAs near the band gap of GaAs at room temperature. A photogenerated longitudinal acoustic phonon wave travels from the top surface of GaSb ...
-
(2011-04-05)Department: Electrical EngineeringThermionic energy conversion is a relatively unexplored technology for the efficient conversion of thermal energy directly to electrical energy. In a thermionic converter, thermally excited electrons are emitted from the ...
-
(2011-08-03)Department: Electrical EngineeringTwo-photon absorption (TPA) has become an important tool for understanding the mechanisms of single-event effects (SEE) in microelectronics. Very little experimental work has been reported that describes the physical ...
-
(2023-03-24)Department: Electrical EngineeringTechnology scaling has increased the density of logic gates impacted by particle strikes, which affects the reliability of digital designs. Also, the impact of process, voltage, and temperature (PVT) variation enhances ...
-
(2018-04-06)Department: MathematicsThis dissertation contributes new results about minor-restricted families of graphs to the field of structural graph theory. A graph G contains a graph H as a minor if H can be formed from G through a sequence of vertex ...
-
(2014-03-27)Department: PhysicsCharacterization and modeling magnetic flux transport within the surface layers of the Sun are vital to explaining the 11 year sunspot cycle. I have characterized the differential rotation (DR) and meridional flow (MF) ...
-
(2023-03-27)Department: NeuroscienceEpilepsy is one of the most common neurological disorders, and current treatments fail to provide seizure control for ~30% of patients. Most pharmacological treatments target ion channels and neurotransmission, yet the ...
-
(2023-11-07)Department: Computer ScienceMedical imaging techniques, such as multi-modality Magnetic Resonance Imaging (MR) and Computed Tomography (CT), have been invaluable for the early detection, diagnosis, and treatment of diseases. The process of annotating ...
-
(2021-04-02)Department: Cell & Developmental BiologyCancer is a heterogeneous disease displaying a variety of cell populations inter- and intra-tumorally. This heterogeneity poses a challenge to cancer treatment, as more heterogeneous cellular populations are more prone to ...
-
(2022-11-22)Department: NeuroscienceAutism has long been considered an empathy related condition, yet empirical evidence supporting this claim has been inconclusive. While most cognitive empathy assessments suggest a decreased capacity for emotion recognition, ...
-
(2009-12-16)Department: Chemical EngineeringBimodal analysis, a cellular-scale approach to studying eukaryotic single cell migration by performing a model-based analysis of single cell video-microscopy data, is described. The bimodal framework that is a generalization ...
-
Characterizing memory space: The neural representational structure of episodic and semantic memory (2022-09-16)Department: PsychologyMemories are not preserved in the past, they help us navigate the present and predict the future. Our representation of the world is constantly evolving as we experience time unfolding continuously, yet our past is made ...
-
(2019-08-08)Department: Hearing and Speech SciencesCognitive rehabilitation following brain injury rests on the ability of clinicians to support their patients’ (re)learning of knowledge, skills, and strategies. Learning and memory are therefore central to the success of ...
-
CHARACTERIZING OPEN CLUSTERS AND SPECTROSCOPIC ECLIPSING BINARIES WITH MACHINE LEARNING FRAMEWORKS (2023-07-18)Department: AstrophysicsIn recent years there has been an explosion of data from space-based and ground-based astronomical surveys. This has led to the necessity of moving away from single-use, boutique analyses to flexible automated data analysis ...
-
(2017-03-22)Department: Hearing and Speech SciencesThe ability to adequately perceive and utilize the prosody of spoken language is important for successful communication. Children with hearing loss who use cochlear implants have demonstrated deficits in perception of ...
-
Characterizing Rare Disease-Causing Mutations in Genes Affecting Cation-Coupled Chloride Cotransport (2020-03-27)Department: NeuroscienceSeveral human diseases have been associated with mutations in genes affecting cation-chloride cotransporters. My dissertation characterizes two single clinical cases with mutations in genes encoding protein kinase D1 (PKD1) ...
-
Characterizing temporal and spatial trends in soil geochemistry on Polder 32, southwest Bangladesh (2015-07-21)Department: Earth and Environmental SciencesSoil samples were collected during three field campaigns to determine seasonal and spatial trends of soil salinity, soil acidity and arsenic concentrations on Polder 32 in coastal Bangladesh. Many farmers on Polder 32 use ...
-
(2021-08-13)Department: Molecular Physiology & BiophysicsFunctional seizures (FS), paroxysmal episodes that present like epileptic seizures but display no aberrant brain electrical patterns, are understudied. Patients have few treatment modalities and a high rate of comorbidities. Our ...
-
(2021-03-25)Department: Biomedical EngineeringFunctional differences are exhibited by the dominant and non-dominant lower limbs during overtly asymmetric bilateral tasks (e.g., kicking a soccer ball). However, current biomechanical analyses of human locomotion typically ...
-
(2013-07-18)Department: Biological SciencesCells that are migrating in a chemical gradient display a polarized distribution of signaling and cytoskeletal components. We have investigated the mechanism of polarity establishment by using the model system Dictyostelium ...
