Utilizing Fitts' Law To Examine Motor Imagery Of Self, Other, And Objects, Sean D. Hinkle Jan 2021

Utilizing Fitts' Law To Examine Motor Imagery Of Self, Other, And Objects, Sean D. Hinkle

Honors Undergraduate Theses

Past research has indicated that motor imagery, or imagined movement, follows Fitts' law similarly to physical movement. Additionally, motor imagery has been shown to improve real motor performance in multiple contexts, showcasing a remarkable connection with real motion. The current study examines how the subject of motor imagery, imagining oneself, another person, or an object, impacts this faithfulness to real movement, specifically in following Fitts' law. Participants viewed 2D photos of a virtual environment with an "X", a humanoid, or a disc facing a gate at 6 distances and 4 widths for 24 combinations.

Phototransduction Components In The Visual System Of Hard-Bodied Ticks, Arimar J. López Limas Jan 2021

Phototransduction Components In The Visual System Of Hard-Bodied Ticks, Arimar J. López Limas

Honors Undergraduate Theses

Ticks are terrestrial invertebrate parasites that attach to their hosts to feed on their blood. Ticks are composed of three families: Ixodidae, Argasidae, and Nuttalliellidae. Ixodid ticks include members of the genera Amblyomma, Ixodes, Haemaphysalis, Hyalomma, Dermacentor, and Rhipicephalus. Ticks can transmit diseases to animals and humans, making them an important organism to study. Current tick-bite mitigation strategies include acaricides (harmful if misused), and CO2 traps (effective in decreasing tick abundance, but costly to use). Since the visual system of ticks has not been studied extensively, I expect that by studying their visual system, alternative tick-bite mitigation …

Traditional Healing Beyond The Homeland: Yezidi Shamanic Healing In The Diaspora, Sophia G. Griemert Jan 2021

Traditional Healing Beyond The Homeland: Yezidi Shamanic Healing In The Diaspora, Sophia G. Griemert

Honors Undergraduate Theses

The goal of this qualitative study is to evaluate whether shamanism, practiced by koçeks and faqrya (the Yezidi terms for traditional shamanic practitioners), continues as a practice among diasporic Yezidis, and, if so, in what manner. I accomplish this through a series of oral, remote interviews with Yezidis living in Germany. The interview subjects comprise a cross-sectional sample that includes men and women from the three Yezidi castes (Sheikh, Pir, Murid). Through the multiple testimonies these interviews garnered regarding shamanic praxis in the context of Germany, I determine that, in spite of the disruptions of forced migration and geographical distance, …

Sequence-Independent Assay For Hiv Viral Load Quantitation, Omar El Merhebi Jan 2021

Sequence-Independent Assay For Hiv Viral Load Quantitation, Omar El Merhebi

Honors Undergraduate Theses

Although nucleic acid tests (NATs) for human immunodeficiency virus (HIV) exhibit many advantages, such as early detection and viral load quantification, over immunological assays, their widespread use is limited by their demand for high-level infrastructure, sophisticated equipment, and advanced staff competence. Furthermore, when quantifying viral loads of patients, it has been reported that these assays can underestimate viral quantities by 22- to 100-fold due to primer-template mismatches in more divergent HIV subtypes. Therefore, we have developed a cost-effective and sequence-independent assay for the detection and quantification of HIV utilizing a modified nucleic acid sequence-based amplification (NASBA) protocol coupled to an …

Chinese Paradox : Where Are Chinese Monuments?, Alberto Castelli Jan 2021

Chinese Paradox : Where Are Chinese Monuments?, Alberto Castelli

Journal of Urban Culture Research

The bareness of the Chinese monumental landscape is the result of various factors, the analysis of which deserves an inquiry into Chinese modus vivendi. Daoist imprimatur and its recognition of nature’s superiority is but one. Buddhist sectarianism, Chinese fluid conception of time, Chinese iconoclasm, are phenomena that, largely, have concurred on creating a periodic tabula rasa of cultural heritage. Making sense of this is simply to recognize that artistic representations are not only metaphors for understanding social dynamics, but also a magnifying glass on the relation between people and their past.

Brain Interhemispheric Alterations In Attention-Deficit Hyperactivity Disorder Using Structural Neuroimaging Features, Cintya Dutta

Electronic Theses and Dissertations, 2020-2023

This dissertation examines brain lateralization and interhemispheric asymmetry patterns found in youths with Attention-Deficit / Hyperactivity Disorder (ADHD). Prior research groups have found mixed findings with respect to left and right hemisphere alterations from ADHD subjects using structural magnetic resonance imaging. In these investigations, we propose the use of Asymmetry Index (AI), a subject-specific metric that quantifies the extent of brain asymmetry and allows each subject to serve as their own control, thus reducing variability when pooling across different sites. We compare AI metric with laterality across volumetric, surface area, thickness, morphology, and white matter measures in order to characterize …

Periodicity Estimation Using Representations In Nested Periodic Dictionaries With Applications In Neural Engineering, Pouria Saidi Jan 2021

Periodicity Estimation Using Representations In Nested Periodic Dictionaries With Applications In Neural Engineering, Pouria Saidi

Electronic Theses and Dissertations, 2020-2023

In this dissertation, we investigate periodicity estimation with nested periodic dictionaries (NPDs), a newly introduced family of matrices that can capture periodicity in the data. We address two main problems. First, we study the detection of periodic signals using their representations in NPDs. To this end, the detection problem is posed as a composite hypothesis testing problem, where the signals are assumed to admit sparse representations in a Ramanujan Periodicity Transform (RPT) dictionary as an instance of NPDs. For the binary case, we develop a generalized likelihood ratio detector and obtain exact distributions of the test statistics in terms of …

Classification Of Ground-Truth Fire Debris Samples Using Neural Networks, Nicholas Thurn Jan 2021

Classification Of Ground-Truth Fire Debris Samples Using Neural Networks, Nicholas Thurn

Electronic Theses and Dissertations, 2020-2023

Fire debris samples are currently analyzed according to ASTM E1618-19, which is the "Standard Test Method for Ignitable Liquid Residues in Extracts from Fire Debris Samples by Gas Chromatography-Mass Spectrometry." This method requires that an analyst make a visual comparison to an appropriate reference sample using the total ion and the extracted ion chromatograms. The analyst then provides an opinion about whether an ignitable liquid residue is present in the sample. The method is inherently subjective due to the visual interpretation that is needed. In order to automate this process, this work uses neural networks and a subset of the …

From An Insect To The Classroom: Evolutionary Insights Into The Ecological And Behavioral Impacts Of Experience, Brooke Kathleen Woelber-Kastner

Doctoral Dissertations

Organisms exhibit suites of life history traits which enable them to respond to environmental stimuli and increase fitness. However, the relationship between organism traits and the environment is not unidirectional, rather they are in a state of constant interaction. To further our understanding of the interactions between the environment and organism phenotypes, this dissertation focuses on a group of insect scavengers, the burying beetles (Coleoptera: Silphidae: Nicrophorus) which utilize carrion to initiate reproduction and feed developing young. Here I apply ecological and molecular methodologies to demonstrate that behaviors provide an important ecological service by sequestering carrion in forest ecosystems. I …

Carbon Emissions From Streams And Rivers: Integrating Methane Emission Pathways And Storm Carbon Dioxide Emissions Into Stream And River Carbon Balances, Andrew Robison Jan 2021

Carbon Emissions From Streams And Rivers: Integrating Methane Emission Pathways And Storm Carbon Dioxide Emissions Into Stream And River Carbon Balances, Andrew Robison

Doctoral Dissertations

River networks play an important role in elemental cycling at watershed, regional, and global scales. They not only serve as pipes that transport elements from land to sea, but also as complex processers that can significantly modify the timing, form, and magnitude of these elemental fluxes. For example, recent studies have shown that river networks contribute significantly to the global carbon cycle by emitting greenhouse gases like carbon dioxide (CO¬2) and methane (CH4) to the atmosphere. However, we currently do not fully understand the controls on GHG emissions from river networks, particularly what drives the variability of emissions across space …
