Machine Learning Models On Prognostic Outcome Prediction For Cancer Images With Multiple Modalities, Gengbo Liu

Theses and Dissertations

Machine learning algorithms have been applied to predict different prognostic outcomes for many different diseases by directly using medical images. However, the higher resolution in various types of medical imaging modalities and new imaging feature extraction framework brings new challenges for predicting prognostic outcomes. Compared to traditional radiology practice, which is only based on visual interpretation and simple quantitative measurements, medical imaging features can dig deeper within medical images and potentially provide further objective support for clinical decisions. In this dissertation, we cover three projects with applying or designing machine learning models on predicting prognostic outcomes using various types of …

The Fundamental Right To Technology, Haochen Sun

Hofstra Law Review

Waves of technological progress in recent decades have tremendously improved quality of life. Meanwhile, concerns about technology-driven injustices, such as unfair distribution of wealth and racial discrimination, have deepened. Experts have cautioned that new technologies could have potentially devastating effects, claiming for instance that artificial intelligence may lead to World War III. We are at a crossroads, and how we harness technology now will determine the future of humanity.

This Article presents a thought experiment, proposing that a new fundamental right to technology be recognized under the U.S. Constitution. Given that technology is of fundamental importance to human dignity and …

Pilosopiyang Pinoy: Uso Pa Ba? (The Relevance Of Filipino Philosophy In Social Renewal), Romualdo E. Abulad

Philosophy Department Faculty Publications

This paper evaluates the titular question and features a summative evaluation and critique of the works and contributions of Leonardo Mercado, Dionisio Miranda, Albert Alejo, Rolando Gripaldo (1947-2017), and Florentino Timbreza to the anthropological and cultural approaches that form a significant part of the discourses on Filipino philosophy. In this piece, Abulad maintains, as in his other writings, that any strict emphasis with regard to methodology restricts the true potential of Filipino philosophy. He buttresses this assertion by invoking postmodernism's 'incredulity towards metanarratives' We should be skeptical about the metanarrative of Filipino identity for it is precisely our rootlessness that …

Emergent Regulatory Systems And Their Challenges: The Case Of Combination Medical Products, George Horvath

Washington Law Review

Where regulatory systems overlap, courts and scholars often focus on the undesirable aspects of the overlap—the ways in which systems conflict. One such context involves the regulation of prescription drugs and medical devices by the FDA’s premarket evaluation processes and by state common-law tort and products liability actions. FDA regulation and state common law are often described as separate, conflicting regulatory systems. This Article challenges that description by proposing a model in which FDA premarket evaluation and state common law function as a single regulatory system. This model brings order to the Supreme Court’s seemingly inconsistent medical products preemption cases, …

Living Links Connecting The United Nations Sustainable Development Goals: Small-Scale Farmers And Agricultural Biodiversity, Susan H. Bragdon

San Diego International Law Journal

The 17 Sustainable Development Goals (SDGs) and Agenda 2030 adopted by the global community in September 2015 are applicable to all countries with the commitment “that no one is left behind.” As an agenda for “people, planet, prosperity, peace and partnership”, Agenda 2030 provides a vision for people and planet-centered, human rights-based, and gender-sensitive sustainable development. It promises “more peaceful and inclusive societies” which are free from fear and violence.

Small scale farmers and agricultural biodiversity are critical to the achievement of aspects of most of the SDGs. In addition to being essential for the resilience and stability of agricultural …

Alternative Conceptions, Initial Knowledge, And Self-Efficacy Of The Novice And Expert Geologist Regarding Mineral Identification, Amanda Manzanares

Master's Theses

Research shows the novice geologist begins an introductory geology course with alternative conceptions about minerals and other geoscience concepts. Students use their prior understanding of these concepts as the basis for future learning. If students’ frameworks include alternative conceptions about foundational geoscience concepts, these could hinder their ability to learn more factual and complicated ideas and facts in the future. It takes time to change these alternative conceptions. For this reason, instructors need to understand their students’ prior understandings of geoscience concepts at the beginning of the courses to move students to a better understanding of the material. Moreover, the …

This study examinedthe connection between the use of self-compassionate focused journal writing prompts and an increase in the levels of self-compassion that a student feltfor him or herself. The purpose of this study was to provide students with the self-compassion tools, strategies, and skills necessary to deal with perceived setbacks in their choreographic process and performance. This quantitative and qualitative study was designed to answer …

Sagebrush Seeds Of Success: A Genetic Analysis Of Bureau Of Land Management Seeds Of Success Seeds And Of Eriogonum Umbellatum, Emily Katherine Schumacher

Master's Theses

Due to the increasing frequency of anthropogenic disturbances, greater effort needs to be put into identifying appropriate seed material for large scale restoration projects. The Bureau of Land Management created the Seeds of Success (SOS) project to increase stocks of native seeds for restoration projects following worsening disturbances. However, there is little known about the genetic composition of these seeds, so it is unclear if these seed accessions will be able to establish healthy and persistent native plant communities. This thesis identified that in 20 accessions of SOS seeds, inbreeding was low to moderate in 17 accessions, allelic richness was …

Sleep Stage Prediction With Raw Acceleration And Photoplethysmography Heart Rate Data Derived From A Consumer Wearable Device, Olivia Walch, Yitong Huang, Daniel Forger, Cathy Goldstein

Mathematics Sciences: Faculty Publications

Wearable, multisensor, consumer devices that estimate sleep are now commonplace, but the algorithms used by these devices to score sleep are not open source, and the raw sensor data is rarely accessible for external use. As a result, these devices are limited in their usefulness for clinical and research applications, despite holding much promise. We used a mobile application of our own creation to collect raw acceleration data and heart rate from the Apple Watch worn by participants undergoing polysomnography, as well as during the ambulatory period preceding in lab testing. Using this data, we compared the contributions of multiple …

Genetic Relationships Using Mitochondrial Versus Nuclear Markers: Is The Catfish Rag1 Gene Suitable For Species Differentiation In The Family Pangasiidae?, Huong Thanh Hoang

Graduate Theses and Dissertations

The Mekong River located in Southeast Asia is a global “hotspot” for aquatic biodiversity. It includes an extensive variety of fish species second only to the Amazon River in South America. Recent studies have revealed the impacts of anthropogenic and climate factors on this river system. Such impacts can result in the formation of barriers, which divide a species population and impede gene flow between separated sub-populations. Barriers influence evolutionary trajectories resulting in the generation of geographic variants or subspecies from an ancestral population. Catfish (Teleostei: Siluriformes) are a key species of the Mekong River ecosystem and are an essential …

Play Now, Pay Later?: Youth And Adolescent Collision Sports, Vivian E. Hamilton

UC Law Journal

The routine and repeated head impacts experienced by athletes in a range of sports can inflict microscopic brain injuries that accumulate over time, even in the absence of concussion. Indeed, cumulative exposure to head impacts—not number of concussions—is the strongest predictor of sports-related degenerative brain disease in later life. The observable symptoms of disease appear years or decades after initial injury and resemble those of other mental-health conditions such as depression and dementia. The years-long interval between earlier, seemingly minor, head impacts and later brain disease has long obscured the connection between the two.

Risk of injury differs across demographics, …

Qualitative Assay To Detect Dopamine Release By Ligand Action On Nicotinic Acetylcholine Receptors, Leanna A. Marquart, Matthew W. Turner, Owen M. Mcdougal

Chemistry and Biochemistry Faculty Publications and Presentations

A pheochromocytoma of the rat adrenal medulla derived (a.k.a. PC12) cell-based assay for dopamine measurement by luminescence detection was customized for the qualitative evaluation of agonists and antagonists of nicotinic acetylcholine receptors (nAChRs). The assay mechanism begins with ligand binding to transmembrane nAChRs, altering ion flow into the cell and inducing dopamine release from the cell. Following release, dopamine is oxidized by monoamine oxidase generating hydrogen peroxide that catalyzes a chemiluminescence reaction involving luminol and horseradish peroxidase, thus producing a detectable response. Results are presented for the action of nAChR agonists (acetylcholine, nicotine, and cytisine), and antagonists (α-conotoxins (α-CTxs) MII, …

Phenotypic And Genotypic Characterization Of Linezolid-Resistant Enterococcus Faecium From The Usa And Pakistan, Kate E Wardenburg, Robert F Potter, Alaric W D'Souza, Tahir Hussain, Meghan A Wallace, Saadia Andleeb, Carey-Ann D Burnham, Gautam Dantas

2010-2019 OA Pubs

OBJECTIVES: Linezolid is an important therapeutic option for the treatment of infections caused by VRE. Linezolid is a synthetic antimicrobial and resistance to this antimicrobial agent remains relatively rare. As a result, data on the comparative genomics of linezolid resistance determinants in Enterococcus faecium are relatively sparse.

METHODS: To address this knowledge gap in E. faecium, we deployed phenotypic antibiotic susceptibility testing and Illumina WGS on hospital surface (environmental) and clinical isolates from the USA and Pakistan.

RESULTS: We found complete concordance between isolate source country and mechanism of linezolid resistance, with all the US isolates possessing a 23S rRNA …

United States Geological Survey: Staff Publications

Pallid Sturgeon Scaphirhynchus albus are endemic to the Missouri and Mississippi river basins and are rare throughout their range. The species was listed as federally endangered with little to no evidence of natural recruitment. Since population augmentation was initiated as a recovery objective in the early 1990s, thousands of hatchery-origin Pallid Sturgeon have been stocked in the lower Missouri River (Gavins Point Dam [river kilometer 1,305.1] to the confluence of the Mississippi River [river kilometer 0.0]). Efforts to discriminate natural reproduction and recruitment of wild-origin Pallid Sturgeon from hatchery-origin fish has been hampered by tag loss in hatchery-origin sturgeon, inconsistent …

Human-Carnivore Relations: Conflicts, Tolerance And Coexistence In The American West, Juan M. Requena-Mullor

Biology Faculty Publications and Presentations

Carnivore and humans live in proximity due to carnivore recovery efforts and ongoing human encroachment into carnivore habitats globally. The American West is a region that uniquely exemplifies these human-carnivore dynamics, however, it is unclear how the research community here integrates social and ecological factors to examine human-carnivore relations. Therefore, strategies promoting human-carnivore coexistence are urgently needed. We conducted a systematic review on human-carnivore relations in the American West covering studies between 2000 and 2018. We first characterized human-carnivore relations across states of the American West. Second, we analyzed similarities and dissimilarities across states in terms of coexistence, tolerance, number …

Pediatric Acute Lymphoblastic Leukemia: A Review, Luke Geierman

Honors Projects

Acute Lymphoblastic Leukemia (ALL) is the most commonly diagnosed pediatric cancer and the most frequent cancer-induced cause of death among young people. Despite this fact, tremendous progress in treating the disease has been made in the last 50 years. This systematic literature review examines the incidence of the disease as well as the importance of risk stratification in treatment planning. The role of genetics in ALL risk stratification, specifically hypodiploidy and hyperdiploidy, is also considered. Finally, current treatment protocols, treatment failure, and the future of research and treatments are all each examined.

Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez

Honors Theses

The success of certain ant species in urban areas is largely unknown. Available food in the environment could affect the composition of ants in urban areas due to a possible relationship between ant physiology and diet. I tested the oil preference of ants as a function of available arthropod prey in urban environments. I hypothesized that as arthropod diversity decreased, ant abundance at oil baits would decrease. Oil is an important nutrient that can affect ant body functions and activities. Ant foraging activities have been found to be affected by lipid depletion. A food source where ants can obtain oil …

Relations Between Self-Regulation, Divergent Thinking, And Perceived Stress In Emerging Adults, Haven Wright

Honors Theses

This study investigated the relationships between self-regulation and stress, self-regulation and creativity, and perceived stress as a mediator for the relationship between self-regulation and creativity. Questionnaires were administered to undergraduate students to individually access each construct. Creativity was measured through divergent thinking and self-regulation was measured through the SRS and effortful control. Regression analyses were run to determine the relationships between the constructs. A negative association was found between effortful control and stress. Individual positive relationships were found between effortful control and all of the creative thinking styles except convergent-unpleasant. Lastly, the indirect effect of effortful control on the convergent-unpleasant …

Climate Change Impacts On Phosphorus Loads In The Upper And Middle Charles River Watershed With Hspf Modeling, Meagan Riley

Graduate Masters Theses

Water quality in the Upper and Middle Charles River Watershed has improved over the past several decades primarily due to improvements statewide in wastewater management. However, climate change threatens this progress, with future projections promising increased precipitation and temperatures for the New England region. This study investigated the impact of climate change projections on total phosphorus loads in the Upper and Middle Charles River Watershed using the HSPF model. Model input data were extended through 2018 to update present day conditions represented by the previously calibrated and validated HSPF model. The updated model was then used to simulate the following …

In Vivo Metabolic And Vascular Response To Hypoxia In Twist Knockdown Murine Breast Cancer, Brandon Sturgill

Graduate Theses and Dissertations

Twist transcription factor is often overexpressed in aggressive tumors. Although needed in early embryonic development for organogenesis, Twist is known to induce an epithelial to mesenchymal transition in cells. In cancer, epithelial to mesenchymal transitions can lead to increased motility and invasiveness. It has also been linked to metabolic reprogramming and increased metastatic risk. Furthermore, metabolic preferences can increase proliferation, enhance metastatic potential, and influence the site of metastasis. We hypothesize that Twist directly affects the metabolism of cancer cells. We expect to see in vivo what we have seen in vitro; Twist overexpression should promote a shift away from …

Investigating Growth Performance And Intestinal Barrier Integrity In Heat-Stressed Modern Broilers And Their Ancestor Jungle Fowl, Travis Tabler

Graduate Theses and Dissertations

Heat stress (HS) has a negative effect on poultry production sustainability due to its adverse consequence on bird welfare, health, growth, and mortality. Although modern broilers have greater gut mass and higher energy use efficiency than unselected birds, they are more vulnerable to HS that induces “leaky gut syndrome,” or increased intestinal permeability. The aim of the current study was to determine the effect of HS on growth performance and gut barrier integrity in three modern broiler lines and their ancestor the Jungle Fowl. Four chicken populations including Giant Jungle Fowl (JF), Athens Canadian Random Bred (ACRB), 1995 Arkansas Random …

American And Iraqi Prose Fiction Of The Iraq War: Traumas Of The Self, Traumas Of The Nation, Ghyath Manhel Alkinani

Graduate Theses and Dissertations

War is so omnipresent in our contemporary world that the story of war is too important to be left to fiction writers to frame and give meaning for. This dissertation provides an analysis of two dominant patterns in contemporary Iraqi and American prose fictional representations of the Iraq War: the individualistic trauma hero narrative and the nationalistic, collective narrative. I argue that the trauma hero myth that dominates American representations of the Iraq War psychologizes and de-politicizes war experience alienating the victim of trauma by decontextualizing their experience and negating the Other. On the other hand, the sweeping nationalistic narrative …
