Essays In The Econometrics Of Choice Analysis With Applications In Health Economics, Maksat Jumamyradov

USF Tampa Graduate Theses and Dissertations

Unobserved heterogeneity is one of the main concerns for applied economists, particularly when modeling preferences for health and healthcare. Applied economists have preferred the mixed logit model due to its flexible latent structure allowing various specifications of unobserved heterogeneity. Since the model does not have a closed-form, its estimation relies on simulation-based methods, specifically the maximum simulated likelihood (MSL) estimator, which has been the dominant estimation strategy. In the first section of this dissertation, which include chapters 1 through 5, I analyze biases of MSL when applied to the bivariate normal, bivariate Poisson-lognormal and mixed logit models.

Repeatability was tested through confirming the correct results are obtained for sample runs performed by the same operator. Reproducibility …

Dynamic Cbct Imaging Using Prior Model-Free Spatiotemporal Implicit Neural Representation (Pmf-Stinr), Hua-Chieh Shao, Tielige Mengke, Tinsu Pan, You Zhang

Faculty, Staff and Student Publications

Objective. Dynamic cone-beam computed tomography (CBCT) can capture high-spatial-resolution, time-varying images for motion monitoring, patient setup, and adaptive planning of radiotherapy. However, dynamic CBCT reconstruction is an extremely ill-posed spatiotemporal inverse problem, as each CBCT volume in the dynamic sequence is only captured by one or a few x-ray projections, due to the slow gantry rotation speed and the fast anatomical motion (e.g. breathing).Approach. We developed a machine learning-based technique, prior-model-free spatiotemporal implicit neural representation (PMF-STINR), to reconstruct dynamic CBCTs from sequentially acquired x-ray projections. PMF-STINR employs a joint image reconstruction and registration approach to address the …

Gte: A Graph Learning Framework For Prediction Of T-Cell Receptors And Epitopes Binding Specificity, Feng Jiang, Yuzhi Guo, Hehuan Ma, Saiyang Na, Wenliang Zhong, Yi Han, Tao Wang, Junzhou Huang

Faculty, Staff and Student Publications

The interaction between T-cell receptors (TCRs) and peptides (epitopes) presented by major histocompatibility complex molecules (MHC) is fundamental to the immune response. Accurate prediction of TCR–epitope interactions is crucial for advancing the understanding of various diseases and their prevention and treatment. Existing methods primarily rely on sequence-based approaches, overlooking the inherent topology structure of TCR–epitope interaction networks. In this study, we present , a novel heterogeneous Graph neural network model based on inductive learning to capture the topological structure between TCRs and Epitopes. Furthermore, we address the challenge of constructing negative samples within the graph by proposing a dynamic edge …

The Unique Role Of The Second Coordination Sphere To Unlock And Control Catalysis In Nonheme Fe(Ii)/2-Oxoglutarate Histone Demethylase Kdm2a, Midhun George Thomas, Simahudeen Bathir Jaber Sathik Rifayee, Saket S. Chaturvedi, Koteswararao Gorantla, Walter White, Jon Wildey, Christopher J. Schofield, Christo Christov

Michigan Tech Publications

Nonheme Fe(II) and 2-oxoglutarate (2OG)-dependent histone lysine demethylases 2A (KDM2A) catalyze the demethylation of the mono- or dimethylated lysine 36 residue in the histone H3 peptide (H3K36me1/me2), which plays a crucial role in epigenetic regulation and can be involved in many cancers. Although the overall catalytic mechanism of KDMs has been studied, how KDM2 catalysis takes place in contrast to other KDMs remains unknown. Understanding such differences is vital for enzyme redesign and can help in enzyme-selective drug design. Herein, we employed molecular dynamics (MD) and combined quantum mechanics/molecular mechanics (QM/MM) to explore the complete catalytic mechanism of KDM2A, including …

Neighboring-Aware Hierarchical Clustering, Ali A. Amer, Muna Al-Razgan, Hassan I. Abdalla, Mahfoudh Al-Asaly, Taha Alfakih, Muneer Al-Hammadi

All Works

In this work, a simple yet robust neighboring-aware hierarchical-based clustering approach (NHC) is developed. NHC employs its dynamic technique to take into account the surroundings of each point when clustering, making it extremely competitive. NHC offers a straightforward design and reliable clustering. It comprises two key techniques, namely, neighboring- aware and filtering and merging. While the proposed neighboring-aware technique helps find the most coherent clusters, filtering and merging help reach the desired number of clusters during the clustering process. The NHC's performance, which includes all evaluation metrics and run time, has been thoroughly tested against nine clustering rivals using four …

Genetic Diversity And Relationships Among Indian Jujube (Ziziphus Mauritiana Lamk.) Cultivars Using Morphometric Characteristics, Matk Barcoding, And Issr Markers, Mahmoud Abdel-Sattar, Rashid S. Al-Obeed, Hail Z. Rihan, Ghada E. El-Badan

School of Biological and Marine Sciences

Indian jujube displays genetic diversity and does not prominently display minute morphometric variations, and this makes correct identification a difficult and long-term task. However, little work has been conducted to bring jujube cultivars into domestication. So, the present study aimed to evaluate eleven cultivars of Indian jujube in terms of the fruit’s morphometric characteristics, as well as molecular marker studies by plastidial megakaryocyte-associated tyrosine kinase (matK) barcoding and inter-simple sequence repeats (ISSR) markers for species differentiation, identification, and relationships among Indian jujube cultivars. The results of the morphometric characteristics showed that the mean geometric diameter, surface area, sphericity, sphericity ratio, …

Design And Test Of Asynchronous Systems Using The Link And Joint Model, Ebelechukwu Esimai

Dissertations and Theses

Asynchronous circuits offer numerous advantages, including low energy consumption and good composability and scalability. However, they remain meagerly adopted in the mainstream semiconductor industry. One reason is the limited number of design tools available to help designers navigate design complexity, particularly the myriad of asynchronous implementation styles.

This dissertation focuses on managing the myriad of asynchronous implementation styles by utilizing a circuit-neutral model, called Links and Joints, and embedding this Link-Joint approach into a design flow. Although years of past work have already laid the groundwork, the work in this dissertation identifies and addresses key missing pieces.

First, the …

Spatiotemporal Alignment Of Event Stream With Images And Active Illumination, Abhijan Wasti

Theses

Unlike conventional frame-based cameras that form images by sampling all pixels within the duration of the global/rolling shutter, a pixel in an event camera can be triggered independently when the log intensity change in scene luminance at the pixel exceeds a threshold. This unique feature provides several advantages over conventional sensors, including high dynamic range (HDR) (≈120dB), high temporal rate (≈10,000Hz), low latency (< 1ms), and low power requirements (≈10mW). These properties make them excellent candidates for applications such as high-speed photography, HDR image reconstruction, object tracking, depth estimation, simultaneous localization and mapping, and surveillance and monitoring. Despite their potential, the asynchronous and spatially sparse nature of events poses challenges to event processing and interpretation. This is because most advanced image processing and computer vision algorithms are designed to work with conventional image formats, and not with temporally dense streams of asynchronous pixel events (i.e., the event stream). Although emerging techniques in supervised machine learning demonstrate promise, continued and rapid progress relies on the availability of labeled event datasets, which are scarce, and difficult to produce. Moreover, generating reliable events for training models is challenging due to the scene-dependent nature of event generation, which is further complicated by varying illumination and relative motion. In this thesis, we attempt to address these limitations with a novel imaging paradigm involving the capture of frames from a conventional frame-based camera that has been spa tially aligned and temporally synchronized with an event sensor. Our active illumination source allows us to generate events more consistently even under challenging illumination and motion in the scene. We demonstrate the feasibility of such a setup for a mobile eye tracking system and acquire subpixel and microsecond accurate spatiotemporal alignment. Our method facilitates the use of pre-trained models that operate on conventional images to detect features that can then be used to train models that can be applied directly to the event stream. This serves as the next step in event-based imaging and unlocks new possibilities in computer vision and imaging technology.

Beyond Bakke: Explaining The Anti-Affirmative Action Movement Of The 1990s, Austin Brayley

The Thetean: A Student Journal for Scholarly Historical Writing

America's long history of racism testifies that despite major reform efforts, American society is not yet egalitarian. Minority racial and ethnic groups emain underrepresented in a number of professional fields such as law, medicine, white-collar business and instructors of higher education. Americans today cannot deny their heritage of discrimination based on race or nationality. In the past, the white majority has denied racial minorities' equal access to these prestigious fields, either through legislation, court rulings or overt resistance.

A War Of Words: Old Testament Slavery Debates In Antebellum Era, Sara Mcconkie

The Thetean: A Student Journal for Scholarly Historical Writing

Rligious leader Joseph Smith put it eloquently when he stated that early nineteenth-century religious leaders "understood the same passages of cripture so differently as to destroy all confidence in settling . .. question[s] by an appeal to the Bible." 1 The debates surrounding slavery during the antebellum era validate Smith's statement. With compelling arguments, religious leaders between 1830 and 1860 condoned and condemned slavery, using the Bible to support their claims.

"We Will Not Be Silent": The White Rose And National Identity In Post-War Germany, Ardis Smith

The Thetean: A Student Journal for Scholarly Historical Writing

In 1942, the White Rose resistance group, composed mainly of German university students, published its first leaflet. As part of a series written by Hans Scholl and Alexander Schmorell entitled the "Leaflets of the White Rose," the tract discussed the need for Germans to acknowledge the inhumane actions of Nazi Germany and encouraged Germans to adopt an attitude of "passive resistance" to the rule of National Socialism. The White Rose hoped to motivate Germans to join the resistance movement by asking "[w)ho among us has any conception of the enormous shame that we and our children will feel when eventually …

Engis Mon Got Two Hed: The Pretense Of Puritan Piety And Underground Racism In Early New Engand, Dallin Henrie

The Thetean: A Student Journal for Scholarly Historical Writing

Many Americans have long credited the Puritans with having laid much of the foundation for what would eventually be generalized as the American character and identity. The nation, they contend, is a product of these hard-working and God-fearing zealots. Others have marveled at this "favoritism" towards the Puritans. After all, other groups arrived earlier than the Puritans and arguably had a larger impact. This controversy has led to many studies of the Puritans. Some have focused on Puritan strengths: their work ethic, moral standards and altruistic character. Like all peoples, however, the Puritans also had their shortcomings. Witchcraft trials, half-way …

The Battle Of King's Mountain: Making History In An Hour, Katelyn Thacker

The Thetean: A Student Journal for Scholarly Historical Writing

Heavy rain in the early morning hours of October 7, 1780, dampened the leaves and allowed the rebel militia to steal through the forest surrounding King's Mountain undetected. The loyalist corps on the top of King's Mountain became aware of the approaching enemy by the rebel's own gunfire scarcely half a mile away. Multiple units of patriot riflemen swarmed the footshaped hill, pushing the loyalist troops to one end of it. In vain, the loyalists attempted to counter showering gunfire with bayonet charges. After only one hour, the loyalist commander British Major Patrick Ferguson lay dead. His subordinate, loyalist Captain …

Probing Charge Recombination In Organic Solar Cells, Ally C. Hurd, Awwad Alotaibi, Acacia Patterson, Obaid Alqahtani, James Doyle, Brian Akira Collins

Macalester Journal of Physics and Astronomy

Printable and flexible organic solar panels are promising sources of inexpensive, large-scale renewable energy, where panels can be manufactured by printing from polymer inks. There are some limitations to these types of solar cells, however. First, toxic halogenated solvents have historically been necessary to dissolve polymers to make the ink. In addition, organic solar cells typically have high rates of recombination, which limits their efficiency. Here, we use a transient photovoltage (TPV) technique to measure charge lifetimes in cells made from two different organic solvents. The first solvent is toxic, halogenated dichlorobenzene (DCB) which is typically used to make organic …

Strain Methods For Changing Local Electric Field Gradient In Bafe2as2, Caleb Williams

Macalester Journal of Physics and Astronomy

In this study, we introduce a novel approach aimed at advancing the investigation of local nematicity in BaFe2As2 via dynamically pulsed strain fields. Our research is motivated by the pursuit of a more sensitive alternative to existing static strain methods. Employing nuclear magnetic resonance techniques, we measure the nuclear quadrupolar energy splittings, utilizing them as a sensitive indicator of the electric field gradient (EFG) that couples strongly to the orbital occupations of the 75As p-orbitals. In the new method, we discern an EFG response through changes in the phase acquired by the nuclear magnetization while time-evolving in the strain field, …

Variability Of High-Degree Modes Over Multiple Solar Cycles Using Local Helioseismic Data From Gong, Nicholas Cebula, Sushanta Tripathy, Kiran Jain, John M. Cannon

Macalester Journal of Physics and Astronomy

In this investigation we use the local helioseismic technique of ring diagrams to study the power, energy, and damping rates of high degree solar acoustic modes. Our data covers the period from the maximum phase of solar cycle 23 to the ascending phase of cycle 25. The goal is to examine the variations in the mode parameters with solar activity as well as the differences between different cycles. For this, we use different proxies of solar activity. We use 10.7 cm radio flux measurements and a measure of magnetic flux known as magnetic activity index from magnetograms.

Ammonia Emission In The Milky Way Galactic Bar Dust Lanes, Charles G. Burton

Macalester Journal of Physics and Astronomy

The Central Molecular Zone (CMZ) of the Milky Way is a region of molecular gas within the inner few hundred parsecs of the Galaxy. This inner region of the Milky Way is hotter and more turbulent when compared with the disk of the Milky Way. Gas is thought to be funneled into the CMZ through dense gaseous dust lanes that are associated with the Galactic Bar. I studied two regions of one of these dust lanes using the NH3 inversion transitions of (J,K) = (1,1), (2,2), (3,3), and (4,4). Data has been obtained from the Green Bank Telescope targeting these …
