Quantum Decoherence In Time-Dependent Anharmonic Systems, Ty Beus Jun 2022

Quantum Decoherence In Time-Dependent Anharmonic Systems, Ty Beus

Theses and Dissertations

This dissertation studies quantum decoherence in anharmonic oscillator systems to monitor and understand the way the systems evolve. It also explores methods to control the systems' evolution, and the effects of decoherence when applicable. We primarily do this by finding the time evolution of the systems using their Lie algebraic structures. We solve for a generalized Caldirola-Kanai Hamiltonian, and propose a general way to produce a desired evolution of the system. We apply the analysis to the effects of Dirac delta fluctuations in mass and frequency, both separately and simultaneously. We also numerically demonstrate control of the generalized Caldirola-Kanai system …

Tensions And Pitfalls In The Depiction Of Multiracial Characters In Children's Picture Books: A Critical Content Analysis, Melody Green Jun 2022

Tensions And Pitfalls In The Depiction Of Multiracial Characters In Children's Picture Books: A Critical Content Analysis, Melody Green

Theses and Dissertations

The United States is becoming more and more multiracial, but little research attends to multiracial characters in children’s picture books. This research employed a critical content analysis using the lens of critical race theory to examine eight children’s picture books published after 2000. This study sought to answer two questions. First, using a critical race theory lens, what patterns and tensions emerge in the depictions of multiracial characters in children’s picture books? Secondly, how do the depictions of multiracial characters in children’s picture books perpetuate deconstructed conceptualizations of multiracial identity? Common themes that presented themselves in this study were (a) …

Towards Color-Based Two-Hand 3d Global Pose Estimation, Fanqing Lin Jun 2022

Towards Color-Based Two-Hand 3d Global Pose Estimation, Fanqing Lin

Theses and Dissertations

Pose estimation and tracking is essential for applications involving human controls. Specifically, as the primary operating tool for human activities, hand pose estimation plays a significant role in applications such as hand tracking, gesture recognition, human-computer interaction and VR/AR. As the field develops, there has been a trend to utilize deep learning to estimate the 2D/3D hand poses using color-based information without depth data. Within the depth-based as well as color-based approaches, the research community has primarily focused on single-hand scenarios in a localized/normalized coordinate system. Due to the fact that both hands are utilized in most applications, we propose …

Methods For Characterizing Groundwater Resources With Sparse In-Situ Data, Ren Nishimura Jun 2022

Methods For Characterizing Groundwater Resources With Sparse In-Situ Data, Ren Nishimura

Theses and Dissertations

Groundwater water resources must be accurately characterized in order to be managed sustainably. Due to the cost to install monitoring wells and challenges in collecting and managing in-situ data, groundwater data is sparse in space and time especially in developing countries. In this study we analyzed long-term groundwater storage changes with limited times-series data where each well had only one groundwater measurement in time. We developed methods to synthetically create times-series groundwater table elevation (WTE) by clustering wells with uniform grid and k-means-constrained clustering and creating pseudo wells. Pseudo wells with the WTE values from the cluster-member wells were temporally …

Being "Rightly Known": Otherness And The Ethics Of Reading In Charlotte Brontë'S Villette, Tin Yan Grace Lee Jun 2022

Being "Rightly Known": Otherness And The Ethics Of Reading In Charlotte Brontë'S Villette, Tin Yan Grace Lee

Theses and Dissertations

Villette (1853), Charlotte Brontë's last novel, is famously riddled with ambiguity: its narrator-protagonist, Lucy Snowe, avoids disclosing details about her childhood, fails to reveal to readers the identity of characters she recognizes from her past, and, at the end of the novel, refuses to confirm if her love interest, M. Paul, has died at sea after a storm. Believing Lucy's ambiguous narrative style to be a tool she uses to train readers to better understand her, many critics have focused their efforts on trying to interpret Lucy's silences and evasions "correctly," thereby turning themselves into Lucy's or Brontë's "ideal" authorial …

An Exploratory Study Of Behavioral Engagement In People With And Without Aphasia: Comparisons And Relationships, Vivian Elisabeth Ward Jun 2022

An Exploratory Study Of Behavioral Engagement In People With And Without Aphasia: Comparisons And Relationships, Vivian Elisabeth Ward

Theses and Dissertations

Previous research suggests that attentional deficits could be the underlying cause of language impairments in people with aphasia (PWA) and that behavioral engagement ratings can be an accurate way to measure attention to specific tasks. Previous research also suggests that PWA have lower levels of behavioral engagement than neurologically healthy adults. Participants in the present study included 9 PWA and 18 neurologically healthy adults. This was an exploratory study investigating the relationships and differences between behavioral engagement and physiological measures, perceived arousal, and naming accuracy and response time in PWA and neurologically healthy adults. Participants completed a confrontational naming task …

The Effects Of Stimulus Type On Interpersonal And Intrapersonal Speech Perception In Typical Adults, Melannee Wursten Ipsen Jun 2022

The Effects Of Stimulus Type On Interpersonal And Intrapersonal Speech Perception In Typical Adults, Melannee Wursten Ipsen

Theses and Dissertations

Children with speech sound disorders (SSD) often have difficulties with speech perception. Speech perception is the ability to intake speech sounds and interpret them for meaning. Understanding children’s speech perception abilities is pertinent because children use perceptual skills to hone accurate production during SSD treatment. Different types of stimuli have been used in speech perception research. At present, it is unclear how different types of speech stimuli differentially impact speech perception in typical listeners or children with SSD. In this study, we investigated perceptual skills for different speech types in neurotypical adults to better understand how stimulus type impacts perception …

The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton Jun 2022

The Behavioral And Neurophysiologic Relationships Between Sensory Processing And Autistic Traits In Emerging Adults, Savanah Calton

Theses and Dissertations

The majority of individuals diagnosed with Autism Spectrum Disorder (ASD) experience sensory processing difficulties that are also associated with greater presence of autistic traits, psychiatric difficulty, and intolerance of uncertainty (IU). These relationships are also expressed in the neurotypical (NT) population, termed the Broader Autism Phenotype (BAP), and present with impacts to daily functioning/well-being just as prominently. However, little is known concerning the neurophysiologic nature of these behavioral relationships, especially in young adults. Thus, the purpose of the current study was to examine the behavioral and neurophysiologic nature of the relationships between sensory processing, autistic traits, and related behavioral functions …

Motivation Across Platforms, Mariia Shishmareva Jun 2022

Motivation Across Platforms, Mariia Shishmareva

Theses and Dissertations

Motivation in language learning has been studied for quite a long time. However, the main focus has been on motivation in face-to-face learning environments. Motivation in online learning can be different due to many factors. This study compared how a language instructor used motivational strategies in face to-face vs. Zoom classes; and how students reacted to these motivational strategies. For these purposes the Motivational Orientation of Language Teaching (MOLT) was used for observations. Results showed that while the teacher used many of the same motivational strategies in both sections, some categories like Social Chat, Referential Questions and Volunteering had significantly …

Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate Jun 2022

Auditory Brainstem Response In Autistic Children: Potential Implications For Sensory Processing, Madelyn Cate

Theses and Dissertations

Autistic people frequently experience sensory processing difficulties. For many on the autism spectrum, such difficulties can significantly impact important functions and quality of life. We are only beginning to understand the neural mechanisms of atypical sensory processing. However, one established way to measure certain levels of auditory processing is with auditory brainstem responses (ABR). While ABR has been primarily hypothesized in the current literature as a means of early detection/diagnosis in autism, additional research is needed to determine the ABR’s utility in examining sensory processing in this population. Thus, we evaluated ABR in 19 young children with autism during various …

"A Poem Is A Gesture Toward Home": Formal Plurality And Black/Queer Critical Hope In Jericho Brown's The Tradition, Kaitlin Hoelzer Jun 2022

"A Poem Is A Gesture Toward Home": Formal Plurality And Black/Queer Critical Hope In Jericho Brown's The Tradition, Kaitlin Hoelzer

Theses and Dissertations

Jericho Brown's The Tradition (2019), which won the Pulitzer Prize for poetry, includes four duplexes, a poetic form of Brown's own invention that combines the sonnet and the blues. Made of fourteen lines separated into seven couplets, the duplex is a complex structure comprised of sets of indents and repeated lines. Brown's use of disparate source forms to create a new form altogether challenges the supremacy of a singular, white American literary tradition, putting it into conversation with other traditions in order to critique its historically racist and heterosexist boundaries. As he does so, Brown works not to abolish "the …

Women's Response To Spousal Pornography Use: A Grounded Theory, Misha Duncan Crawford Jun 2022

Women's Response To Spousal Pornography Use: A Grounded Theory, Misha Duncan Crawford

Theses and Dissertations

Empirical research suggests that married women may more commonly experience spousal pornography use as a relational attachment threat and are more likely to experience negatively associated relational outcomes such as distress and loss of trust. The purpose of this study was to develop a grounded theory of women’s response to concealed spousal pornography use. This study included the experiences of 30 women who reported spousal pornography use as a threat to relational attachment and demonstrated evidence of individual and relational healing thereafter. The research question, “How do women describe the experience of learning of their spouse’s pornography use and the …

Synthesis And Applications Of Α,Β-Dehydroamino Acid-Containing Peptides, Diego A. Moya Jun 2022

Synthesis And Applications Of Α,Β-Dehydroamino Acid-Containing Peptides, Diego A. Moya

Theses and Dissertations

Yaku’amide A (YA) is a linear anticancer peptide that is rich in bulky dehydroamino acids (ΔAAs) and β-hydroxyamino acids (β-OHAAs). In our recent total synthesis of YA, we featured a one-pot anti dehydration–azide reduction–O→N acyl transfer process for the stereospecific construction of Z- and E- ∆Ile residues. Despite previous total syntheses and our efforts, the synthesis of YA remains lengthy. Via computational studies, we identified two analogue peptides that closely resemble the conformation of YA. The use of simpler and symmetrical bulky ΔAAs such as dehydrovaline (ΔVal) and dehydroethylnorvaline (ΔEnv) as surrogates of ∆Ile, along with azlactone chemistry for their …

Amino Acids As Alternatives To Emulsifying Salts In Processed Cheese Analogues, Jeremy Thomas Pack Jun 2022

Amino Acids As Alternatives To Emulsifying Salts In Processed Cheese Analogues, Jeremy Thomas Pack

Theses and Dissertations

Background: Manufacturers have used emulsifying salts universally in the processed cheese industry since James L. Kraft patented the first processed cheese in 1916. My objective was to find alternative ingredients to replace emulsifying salts in processed cheese formulations; the product would follow "clean-labeling" trends and lower the final formulation's sodium content. Materials and Methods: My experiments followed conventional processed cheese formulations to create experimental batches, which were compared to positive and negative controls for significance. Textural, rheological, and melting tests evaluated objective cheese parameters. We observed subjective sensory properties through qualitative descriptive analysis, consumer acceptance panels, and focus groups. Results: …

Progress On Static Structures In Leaky Mode Waveguides, Manusha Korimi

Theses and Dissertations

Virtual reality (VR) head-mounted displays provide a high definition, immersive experi-ence to the viewer. However, most existing technologies have flaws like bulky design and vergence-accommodation conflict that may cause stress in the neck muscles, posture issues, nausea, motion sickness and dizziness. Similarly, augmented reality (AR) displays, which use transparent light modulators, exist, but they possess low field of view and a limited number of discrete depth planes when wide field of view and continuous depth would be ideal. The ultimate goal of my research is use leaky mode waveguide devices to create wide-view angle, transparent near eye holographic displays for …

The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs Jun 2022

The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs

Undergraduate Honors Theses

Aggrephagy, a type of autophagy, is an essential cellular process by which protein aggregates are collected and broken down in the lysosome. Protein aggregates are implicated in several diseases including Alzheimer’s disease, diabetes, and cancer. Here, we investigate the ATG13-ATG101 protein complex, a sub-complex of the canonical ULK1 complex whose regulatory role in aggrephagy is not completely understood. We also develop a protein fragment complementation (PFC) assay using the biotin ligase TurboID to study the functions of the ATG13-ATG101 complex with increased specificity. We demonstrate that ATG13 is required for optimal degradation of p62-ubiquitin condensates. We also show that a …

A Molecular Taxonomy Of Cottus In Western North America, Michael K. Young, Rebecca Smith, Kristine L. Pilgrim, Daniel J. Isaak, Kevin S. Mckelvey, Sharon Parkes, Jacob Egge, Michael K. Schwartz

Western North American Naturalist

The taxonomy of sculpins (Cottus, Cottidae) remains one of the last major unresolved puzzles in the systematics of North American freshwater fishes. We used molecular approaches to identify candidate taxa and their distribution across western North America. We crowd-sourced the collection of specimens (n = 8272) via outreach to biologists in the western United States and Canada. From that collection, we sequenced—at up to 2 mitochondrial and 2 nuclear genes—a subset (n = 4009) of specimens from most basins in the western United States, added sequences from public sequence databases, and applied an array of species …
