Intelligent Cinematic Camera Control For Real-Time Graphics Applications, Ian Harris Meeder

Master's Theses

E-sports is currently estimated to be a billion dollar industry which is only growing in size from year to year. However the cinematography of spectated games leaves much to be desired. In most cases, the spectator either gets to control their own freely-moving camera or they get to see the view that a specific player sees. This thesis presents a system for the generation of cinematically-pleasing views for spectating real-time graphics applications. A custom real-time engine has been built to demonstrate the effect of this system on several different game modes with varying visual cinematic constraints, such as the rule …

The World Coral Conservatory: A Noah's Ark For Corals To Support Survival Of Reef Ecosystems, Didier Zoccola, Nadia Ounais, Dominique Barthelemy, Robert Calcagno, Françoise Gaill, Stephane Henard, Ove Hoegh-Guldberg, Max Janse, Jean Jaubert, Hollie Putnam, Bernard Salvat, Christian R. Voolstra, Denis Allemand

Global change causes widespread decline of coral reefs. In order to counter the anticipated disappearance of coral reefs by the end of this century, many initiatives are emerging, including creation of marine protected areas (MPAs), reef restoration projects, and assisted evolution initiatives. Such efforts, although critically important, are locally constrained. We propose to build a “Noah's Ark” biological repository for corals that taps into the network of the world’s public aquaria and coral reef scientists. Public aquaria will serve not only as a reservoir for the purpose of conservation, restoration, and research of reef-building corals but also as a laboratory …

Exploring The Relationship Between Diversity Training And Counselor Competence In Working With Cisgender Men Wearing Makeup, Brandi Velasquez Nash

UNF Graduate Theses and Dissertations

The concepts of gender and sexuality within counselor diversity training continue to expand and change over time; therefore, it is essential that mental health professionals are knowledgeable of the challenges faced by gender nonconforming (GNC) individuals, specifically cisgender men who wear makeup. This includes being aware of the biases and stigmas that GNC individuals face and understanding how those barriers affect their mental health.

Elements that are applicable to this population include: (a) the historical significance and implications of cisgender men who wear makeup, (b) social media platforms where cisgender men showcase their makeup skills, (c) cultural experiences of GNC …

Mindful Practices For Law Practices, Susan Greene

Hofstra Law Faculty Scholarship

For lawyers who operate in a near-constant state of stress with high-tech, fast-paced stimuli at each turn, it could be the practice of mindfulness that is the key to settling into the practice of law. Mindfulness reaps near countless benefits. This article explores mindful practices and focuses on the ways in which mindfulness improves communication by developing the practitioner's comfort with silence, itself a powerful tool to encourage others to speak openly, by increasing the practitioner's empathy, by helping the practitioner develop a strong sense of self, and by reducing stress, one of the main roadblocks to effective communication.

When Agencies Make Criminal Law, Brenner M. Fissell

Hofstra Law Faculty Scholarship

The nondelegation doctrine prohibits a legislature from delegating its power to an administrative agency, yet it is famously underenforced — even when the delegation results in the creation of criminal offenses (so-called “administrative crimes”). While this practice appears to scandalize the hornbook presumption that legislatures alone define criminal offenses, it has long been ratified by the Supreme Court, and has received little scholarly attention. The few commentators who have addressed administrative crimes highlight the intuition that criminal sanctions are uniquely severe, and thus deserving of a more rigorous nondelegation analysis, but they stop there. They do not precisely link the …

Novel Mechanisms Of Nitric Oxide Activation In The Kidney, Randee Sedaka

All ETDs from UAB

Globally, adult sodium consumption has far exceeded daily intake recommendations, leading to one in ten cardiovascular deaths. Given the rise in hypertension prevalence, uncontrolled hypertension with antihypertensive medication use, and significant associations between high salt intake and high blood pressure, there is a need to better understand the mechanisms involved in hypertension. Nitric oxide synthase 1 (NOS1) is a well-established regulator of fluid and electrolyte balance in the renal collecting duct (CD) with highest activity in the inner medulla (IM). We previously reported that high salt (HS) intake stimulates CD endothelin B receptor (ETBR)/NOS1-dependent generation of NO, thereby inhibiting the …

Diurnal Dysfunction In Control Of Sodium Excretion In Diet-Induced Obesity, Reham Soliman

All ETDs from UAB

The renal endothelin system plays a key role in sodium excretion, particularly under high salt (HS) diet. HS stimulates renal endothelin-1 (ET-1), which binds and activates the endothelin receptor B (ETB) to excrete the excess salt. Loss of ETB receptor is linked to the development of hypertension under HS. Central clock genes are important in maintaining rhythmic patterns of sodium excretion and ET-1 is identified as a target for clock genes, including Period and Bmal1. ET-1 excretion follows a diurnal rhythm along with sodium excretion. Sexual dimorphism is evident in the diurnal regulation of endothelin-mediated natriuresis and its downstream targets. …

Mitochondrial Priming Of Tumor Initiating Cells Involves Repression Of Mitochondrial Fission Activity Towards Redox Regulation Of The Cell Cycle Regulator Cyclin E, Brian Spurlock

All ETDs from UAB

Mitochondrial dynamics primarily refers to the opposing fission or fusion events between individual mitochondria, which maintains steady-state mitochondrial morphology in cells. Fission and fusion activities maintain the energetics of normal and neoplastic stem cells. We developed the novel approach mito-SinCe2 to study the bidirectional relationship between mitochondrial dynamics and energetics. Application of this method led to the hypothesis that mitochondria-dependent ovarian tumor initiating cells interconvert between 3 states with distinct mitochondrial energetics/dynamics relationships. Cells in one state, characterized by high mitochondrial ROS and low fission activity, appear to be primed for self-renewal by mitochondria. We call these cells mitochondria-primed stem …

Role Of Endogenous Tau In Lewy-Like Pathology, Lindsay Stoyka

All ETDs from UAB

Lewy Body Diseases (LBDs) are a group of disorders characterized by intracellular inclusions of misfolded alpha-synuclein (α-synuclein). Of these, Parkinson’s Disease (PD) is the most common neurodegenerative movement disorder, and Dementia with Lewy Bodies (DLB) is the second most common neurodegenerative dementia. PD is characterized clinically by bradykinesia, resting tremor, rigidity, and postural instability. In addition, up to 80% of patients eventually develop dementia, termed Parkinson’s Disease Dementia (PDD). DLB is characterized by onset of dementia before or concurrently with parkinsonism. Currently, no disease-modifying therapies exist for either of these diseases. Lewy pathology is found in regions important for cognition …

Assessing The Potential Of Public Transit Utility In Medium-Sized Cities Using Agent-Based Simulation, Taniya Sultana

All ETDs from UAB

At the beginning of the twentieth century, the United States was leading in the public transit sector, but following World War II, private car trips became more affordable and more popular, specially, in the last few decades. Transportation infrastructure investments that increased road capacity enabled the development of suburbs leading to urban sprawl and increase in automobile use at the expense of reduced public transit ridership. With the increase of dependency in automobiles and the continuing growth of private automobile ownership and use, various problems became major challenges in big cities of USA. These include traffic congestion, air pollution, road …

The first contribution of the dissertation solves the problem of partial observability when non-linear function approximators are used for learning stochastic policies. The second contribution optimizes the problem of maximizing the total expected rewards. The third contribution trains the agent in a photo-realistic environment with a real physics engine. To achieve these goals, a deep Q-network that combines double and dueling architectures is adopted as a value function approximator, and the prioritized experience replays the sample …

Mid-Fusiform Sulcus Anatomy And Its Relationship To Face Processing And Social Functioning In Autism Spectrum Disorder, Carla Ammons

All ETDs from UAB

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and restricted and repetitive behaviors and interests. One of the most consistent findings in ASD is reduced attention to and atypical processing of faces. However, the brain basis of aberrant face processing in ASD remains opaque. A novel neuroanatomical feature, the mid-fusiform sulcus (MFS), is strongly associated with face-selective regions of the fusiform gyrus (FG) as well as other large-scale functional and structural divisions in the ventral temporal cortex (Weiner et al., 2014). However, this feature is unexplored in ASD. The overarching goal of this dissertation …

Prediction Of The Optimal Catheter Placement Selection For Therapy Infusion To Treat Brain Tumors, Lisa Hope Antoine

All ETDs from UAB

ABSTRACT In 2020, the National Brain Tumor Society reported that physicians would diagnose more than 87,000 new cases of brain tumors. These cases will add to the approximately 700,000 individuals in the United States living with brain and central nervous system tumors. Almost 18,000 of these cases will prove fatal [1]. The blood-brain barrier (BBB) hinders the effective treatment of brain tumors. The task of this barrier is to protect the brain from composition instabilities in blood plasma and shield the brain from agents that may adversely impact brain functionality. However, by performing its tasks the barrier prevents potential effective …

Understanding The Impact Of Diet And Obesity On Anti-Tumor Immunity And Therapeutic Efficacy In Kidney Cancer, Rachael Miller Orlandella

All ETDs from UAB

Obesity is regarded as a major risk factor for developing renal cell carcinoma (RCC). Advanced-stage RCC exhibits chemotherapeutic resistance, but is responsive to immunotherapies such as the immune checkpoint inhibitor anti-programmed cell death-1 (anti-PD-1). Despite some clinical successes, response rates remain low for anti-PD-1 monotherapy (20-30%). Preclinical evaluations of immunotherapeutic strategies typically use lean mice and do not account for patient comorbidities. This may explain the underwhelming success rates following clinical translation of new cancer treatments. Recent studies found that obesity was associated with favorable outcomes and responses to immunotherapy in melanoma. However, the effects of obesity on anti-tumor immunity …

Role Of Trib3 In Progression And Pathogenesis Of Diabetic Retinopathy, Priyamvada Milind Pitale

All ETDs from UAB

Diabetic retinopathy (DR) is reported to be one of the leading causes of blindness in the United States by Center for Disease Prevention and Control. As the estimated prevalence of the disease will likely triple by 2020, the research in this area should focus on identifying novel targets and therapeutic approaches. One of the therapeutic approaches for DR is the reprograming of retinal metabolism to delay the progression of the disease. The unfolded protein response (UPR) is recognized as a cellular pathway activated in diabetic retina which interacts with key transcription factors to physiologically regulate glucose, lipid homeostasis, and angiogenic …

Investigating Growth-Related Hormones And Their Roles In Metabolism In Fish Skeletal Muscle, Ross Michael Lee Reid

All ETDs from UAB

The endocrine system is essential for the maintenance and regulation of skeletal muscle growth and metabolic processes, as secretions of growth-related hormones directly regulate these systems. The roles of these growth-related hormones are well understood in mammals yet are not well defined in teleosts. Thus, the work outlined in these chapters provides novel insight for the actions of two growth-related hormones, Growth Hormone (GH) and Teneurin C-terminal Associated Peptide (TCAP), in fish skeletal muscle. First, Chapter 2 highlights the work expanding the application of resazurin as a novel method of in vivo metabolic assessment across fish life-stages, which was utilized …

Investigating The Roles Of The Renal Primary Cilium Through The Use Of Intravital Imaging, Dustin Zachary Revell

All ETDs from UAB

Primary cilia are small microtubule based appendages present on nearly every cell type in the mammalian body, and are highly conserved from organisms as simple as algae to humans. Cilia function as complex signaling centers integrating a variety of pathways and play critical roles throughout development and in maintaining homeostasis. Mutations to ciliary proteins in humans result in a wide array of diseases termed ciliopathies, which have a broad range of symptoms affecting nearly every organ in the body. Renal primary cilia are present on the apical side of tubular epithelium, where they project into the lumen and are thought …

Tools To Evaluate Nanodiamond-Mediated Delivery Of Tiopronin For Cataract Prevention, Justin Beltz

Doctoral Dissertations

”There is a growing demand for non-surgical means of cataract treatment. This dissertation presents three bodies of work that reflect the early-stage development of eye drop formulations aimed at delaying cataract progression. These formulations consist of the antioxidant 2-mercaptopropionylglycine (MPG) loaded onto nanodiamond particles.

Cataractogenesis is linked to oxidative damage to lens proteins. To investigate the potential of MPG for protection against oxidative damage, A549 cells were incubated in 0.6 mM tert-butylhydroperoxide (tBHP). Cells exposed to tBHP without MPG exhibited elevated levels of reactive oxygen species, which led to the depletion of the vital antioxidant glutathione and, ultimately, apoptosis. Co-administration …

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

The field of nanotechnology has been gaining great success due to its potential in developing new generations of nanoscale materials with unprecedented properties and enhanced biological responses. This is particularly exciting using nanofibers, as their mechanical and topographic characteristics can approach those found in naturally occurring biological materials. Electrospinning is a key technique to manufacture ultrafine fibers and fiber meshes with multifunctional features, such as piezoelectricity, to be available on a smaller length scale, thus comparable to subcellular scale, which makes their use increasingly appealing for biomedical applications. These include biocompatible fiber-based devices as smart scaffolds, biosensors, energy harvesters, and …

Development And Testing Of Artificial Membranes For Rearing Of Rhipicephalus Microplus, The Southern Cattle Fever Tick, Ann T. Vacek, John A. Goolsby, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The southern cattle fever tick, Rhipicephalus microplus, is a livestock pest worldwide in tropical and subtropical climates, including South Texas, and can vector Babesia spp., the causal agents of bovine babesiosis. Artificial rearing methods for R. microplus are needed, especially for rearing specialist tick parasitoids that are under evaluation for classical biological control. In this study, we tested the efficiency of artificial feeding of R. microplus larvae, nymphs, and adults on a siliconized substrate (goldbeater’s membrane, lens paper, or Hemotek), or on nonsiliconized goldbeater’s membrane or Hemotek. Other variables tested were a warm water bath, incubator, positioning blood above or …

Adapting New Technologies For Evaluating The Ecology And Distribution Of The Diamondback Terrapin (Malaclemys Terrapin) In Alabama, Nicole Mckim Conner

All ETDs from UAB

The diamondback terrapin (Malaclemys terrapin), an emydid turtle that plays an important ecological role in salt marsh ecosystems, has declined over the last century and is listed as a Priority One Species (highest conservation concern) in Alabama. Traditional surveying techniques have been employed to monitor diamondback terrapins on the coast of Alabama throughout the last decade; yet, these techniques can be time-consuming, labor-intensive, and disruptive to terrapins and their habitats. This study evaluated the potential for UAS technology and eDNA methodologies to effectively monitor diamondback terrapin presence, abundance, and/or distribution in salt marsh habitats. UAS-based surveys were conducted in 2017 …

An Evaluation Of Ontogenetic Allometry Of Defensive And Nutrient Acquisition Properties Of Select Skeletal Components Of The Regular Sea Urchin Lytechinus Variegatus, Raven Amber Edwards

All ETDs from UAB

Ontogenetic allometric analyses can provide novel insights into aspects of evolution, ecology, and conservation. For example, a recent study found marine fish exhibit hyperallometric scaling of reproductive output in relation to body size. Accordingly, to sustain fish populations the largest size class of fish should be protected. The present study exploits a model sea urchin to explore allometry to evaluate the ontogeny of skeletal defense and feeding efficiency (Aristotle's lantern). Lytechinus variegatus were sampled from St. Joseph Bay, Florida. A range of different sized late juvenile to adult individuals were measured and then dissected into skeletal components. Skeletal defense was …

Genome-Wide Mirna Regulation Of Stress Susceptibility Across The Brain In A Rodent Model Of Early Life Stress, Lauren Alexis Allen Mckibben

All ETDs from UAB

Early life stress (ELS) affects a significant portion of the US population in the form of various types of abuse and neglect, as well as household dysfunction and loss of a loved one, among others. Although these experiences happen early in life, they increase risk for mental health disorders, especially major depression (MDD), across the lifespan. MDD is a debilitating psychiatric disorder marked by periods of depressed mood and loss of pleasure in once enjoyable activities. Patients with MDD also report trouble sleeping, unintentional weight loss or gain, feelings of worthlessness, and suicidal ideation. MDD is associated with annual $100 …

T Cells In Synucleinopathies, Gregory Paul Williams

All ETDs from UAB

Synucleinopathies, which include Parkinson disease (PD), dementia with Lewy Bodies (DLB), and multiple system atrophy (MSA), are a collection of neurodegenerative diseases that are in major part defined by the presence of alpha-synuclein (α-syn) rich protein aggregates in the brain. Increasing evidence has highlighted a neuroinflammatory phenotype also associated with these synucleinopathies. This neuroinflammatory phenotype includes the activation of central nervous system (CNS) microglia, increased pro-inflammatory cytokines, and the infiltration of peripheral T cells into the CNS. We sought to further explore the T cell responses associated with PD and MSA. Using two preclinical mouse models of PD and MSA, …

Co-Factors In Fgf Signaling, Christopher Yanucil

All ETDs from UAB

The fibroblast growth factor (FGF) family consists of a group of proteins whose diverse biological functions are mediated by receptor tyrosine kinases, termed FGF receptors (FGFR) 1-4. While paracrine FGFs require heparin sulfate as a co-factor for FGFR bind-ing and signaling, it has been assumed that endocrine FGFs, such as FGF23, do not bind heparin but instead require klotho, a family of transmembrane proteins, as a co-receptor on specific target cells. FGF23 acts as bone-derived hormone that targets tubular epitheli-al cells in the kidney via FGFR1 and α-klotho to reduce renal phosphate uptake. In chron-ic kidney disease (CKD), the kidney …
