Spanish And English Phoneme Recognition By Training On Simulated Classroom Audio Recordings Of Collaborative Learning Environments, Mario J. Esparza Perez

Electrical and Computer Engineering ETDs

Audio recordings of collaborative learning environments contain a constant presence of cross-talk and background noise. Dynamic speech recognition between Spanish and English is required in these environments. To eliminate the standard requirement of large-scale ground truth, the thesis develops a simulated dataset by transforming audio transcriptions into phonemes and using 3D speaker geometry and data augmentation to generate an acoustic simulation of Spanish and English speech. The thesis develops a low-complexity neural network for recognizing Spanish and English phonemes (available at github.com/muelitas/keywordRec). When trained on 41 English phonemes, 0.099 PER is achieved on Speech Commands. When trained on 36 Spanish …

Comparative Genomics Methods And Applications, Emily N. Alden

Biomedical Sciences ETDs

Virtually all fields of biology have benefited from the advancements in comparative genomics technologies, specifically in the study of evolution. In this dissertation I develop and use comparative genomic technologies to investigate the novel SARS-CoV-2 virus, assembly the first genome of the black lace domestic angelfish and identify germline genetic variants associated with altered breast cancer-specific survival. Our genome tiling array for the novel coronavirus presents a rapid and cost-effective method to sequence the entire viral genome and can be used to track the rapid evolution of viral variants in the population. The domestic angelfish is a member of the …

Optimal Transport Driven Bayesian Inversion With Application To Signal Processing, Elijah F. Perez

Mathematics & Statistics ETDs

This paper will outline a Debiased Sinkhorn Divergence driven Bayesian inversion framework. Conventionally, a Gaussian Driven Bayesian framework is used when performing Bayesian inversion. A major issue with this Gaussian framework is that the Gaussian likelihood, driven by the L2 norm, is not affected by phase shift in a given signal. This issue has been addressed in [1] using a Wasserstein framework. However, the Wasserstein framework still has an issue because it assumes statistical independence when multidimensional signals are analyzed. This assumption of statistical independence cannot always be made when analyzing signals where multiple detectors are recording one event, say …

Correlating Diffusional Dynamics And Receptor Tyrosine Kinase Function Using Single Quantum Dot Tracking, Irais Ortiz Caraveo

Biomedical Engineering ETDs

Epidermal growth factor receptor (EGFR) signal transduction is initiated via ligand (EGF) binding, followed by dimerization, autophosphorylation of the C-terminal tails, and recruitment of proteins that form a larger signaling complex to propagate the signal. We explored the relationship between receptor mobility and signaling using single-particle tracking (SPT) by examining the diffusional dynamics of EGFR and two truncation mutants to understand whether mobility changes are correlated with signaling. Results revealed that phosphorylation of the C-terminal tail of EGFR is required for maximal reduction in mobility that occurs with EGF stimulation, indicating that receptor mobility is a read-out for receptor signaling. …

Fundamental Aspects Of The Interaction Between Light And Nanostructures, Stephen Keith Sanders

Physics & Astronomy ETDs

Recent breakthroughs in nanophotonics have brought new opportunities to control and manipulate light at the nanoscale. The optical properties of metallic nanostructures have attracted particular interest because of their plasmon resonances, which couple strongly with visible light, and generate large near-field enhancements in their vicinity. In the first part of this thesis, we investigate the fundamental limits of the local density of photonic states near nanostructures by analyzing a sum rule relating its spectral integral to the field induced by a static dipole. Next, we analyze how the design of metallic nanoantennas can benefit from incorporating active materials that display …

Closing The Loop And Opening The Possibilities: Augmenting Sleep-Dependent Consolidation To Improve Long Term Memory, Aaron Paul Jones

Psychology ETDs

Memory consolidation occurs during slow-wave sleep. This is a complex process that can be studied using electroencephalography (EEG) and modulated with brain stimulation. Previous studies have shown that transcranial alternating current stimulation (tACS) can be used to entrain or disrupt endogenous oscillations in cortical networks and can be used for the manipulation of consolidation processes during sleep. In this series of experiments, sleep-dependent memory consolidation was modulated using closed-loop tACS (CL-tACS to improve memory performance for three tasks: a verbal paired associates task (PAT), an interference paired associates task (iPAT), and a visual category learning task. EEG was collected during …

In Pursuit Of Comparability: Evaluating Influence And Interaction Among Components Of The Home Range Estimation Process In Chimpanzee Datasets, Jillian J. Rutherford

Geography ETDs

The home range (HR) is a fundamental manifestation of an animal’s spatial behavior, but its study has been limited by unclear, unreliable, and unstandardized methodological approaches for measurement. The lack of a comprehensive evaluation of the influence of components of the HR estimation process has hampered consensus over best practices for collecting and analysing movement data. This leads to wide variation in practice, thwarting direct comparability between HR estimates and curtailing the cohesive power of cross-study findings necessary for testing hypotheses and developing appropriate conservation and management strategies. In this thesis I explore the influence of and interaction between common …

Client Heart Rate Variability In Motivational Interviewing For Alcohol Use, Brigitte R. Stevens

Psychology ETDs

Heart Rate Variability (HRV) is a useful tool for clinical practice and substance use research, as it may provide insight into liability for relapse or development of addiction, as well as provide indicators of recovery outcomes and response to treatment. Psychotherapy would benefit from an integrated understanding of physiological regulation systems such as what are measured by HRV, as HRV is linked to psychopathology and substance use disorders.

HRV was measured in non-treatment-seeking adult drinkers as they underwent a motivational interviewing (MI) session. Subjects’ HRV from the interview was then regressed on therapist MI-consistent behaviors. The subjects’ drinking at both …

Impact Of Riverside Drains On Surface-Water And Ground Water Interactions In The Middle Rio Grande, New Mexico: Implications To The Sustainability Of Native Cottonwoods (Populus Deltoides Ssp. Wislizenii) And Native Species, Gerardo Rodriguez

Water Resources Professional Project Reports

The Middle Rio Grande riparian zone, named the Bosque, provides cultural, aesthetic, environmental, recreational, and historical value to the residents of the Middle Rio Grande valley. Most of the Bosque has not experienced successful native cottonwood (Populus deltoides ssp. wislizenii) recruitment since the completion of the Cochiti reservoir and most of the Bosque cottonwood forest is senescing. This decline of the native species in the Bosque can be attributed to highly managed hydrology of the riparian zone. The levees and agricultural drains managed by the Middle Rio Grande Conservancy District (MRGCD), that borders both sides of the river, also affect …

Individual Exposure Potential Assessment For Livestock Based On Spatial-Temporal Analysis Of Gps Data And Behavior Patterns Classification In Cove Wash Watershed, Arizona, Zhuoming Liu

Geography ETDs

This thesis examined the geospatial and temporal grazing patterns of domesticated livestock to model individual-level exposure potential to abandoned uranium mine (AUM) waste in a tribal community in the Southwest United States. Lotek Litetrack Global Positioning System (GPS) collars collected data at 20-minute-intervals for 2 flocks of sheep and goats during the Spring and Summer of 2019. Depending on the flock and individual animals, tracking time ranges from 10 days to four months. This research developed a GIS-based exposure potential framework that built on existing methodologies in time geography, GIS, and exposure mapping. This thesis aims to: 1) classify GPS …

Searching For The Global 21 Cm Cosmic Dawn Absorption Signal With The Long Wavelength Array, Christopher Dilullo

Physics & Astronomy ETDs

The redshifted 21 cm signal from neutral hydrogen offers one of the best observational probes of Cosmic Dawn and the Epoch of Reionization. This dissertation presents an effort to detect the redshifted 21 cm signal using the Long Wavelength Array station located on the Sevilleta National Wildlife Refuge in New Mexico, USA (LWA-SV). The major goal is to validate the potential detection reported by the EDGES collaboration. This measurement requires a dynamic range on the order of 10⁵ in order to disentangle the cosmological signal from the Galactic foregrounds. The beamforming capability of LWA-SV is novel to this search. …
