Precisely-Engineered Brush Active-Layer And Biomimetic Membranes For Aqueous Separations, Cassandra Porter Apr 2022

Precisely-Engineered Brush Active-Layer And Biomimetic Membranes For Aqueous Separations, Cassandra Porter

Yale Graduate School of Arts and Sciences Dissertations

Currently, a third of the world lives in areas with inadequate or unsafe water supply, with a projected shortage for at least half the population by 2025. With 97% of the Earth’s water contained in the ocean, improving desalination technology and other aqueous separations could be a solution. At present, the best polyamide thin film composite reverse osmosis (TFC-RO) membranes require 2 times the theoretical minimum energy to desalinate. Furthermore, these membranes cannot sufficiently reject in one pass certain solutes, like boron and chloride, to stringent regulatory levels. Additionally, other aqueous separations are important for the pursuit of environmentally sustainable …

Every Day About The World: Feminist Internationalism In The Second Wave, Samuel Huber Apr 2022

Every Day About The World: Feminist Internationalism In The Second Wave, Samuel Huber

Yale Graduate School of Arts and Sciences Dissertations

“Every Day About the World” offers a new narrative of US second-wave feminism from its emergence in the 1960s through its institutionalization in the 1980s, recuperating a foundationally international horizon through which feminist literature and analysis were formulated, tested, and revised. By attending to a series of pivotal but under-considered scenes of engagement for US feminism, I describe the political and conceptual challenges confronted by US feminist writers as they looked beyond national borders, as well as the literary approaches through which those challenges were registered and occasionally surmounted. Solidarity with anti-imperialist movements abroad provided consistent occasions for US feminists …

Discovery Of Novel Cancer Immunotherapy Targets With Next Generation Genome Engineering Methods, Jonathan Joon-Young Park Apr 2022

Discovery Of Novel Cancer Immunotherapy Targets With Next Generation Genome Engineering Methods, Jonathan Joon-Young Park

Yale Graduate School of Arts and Sciences Dissertations

Recent advances in immuno-oncology have led to remarkable clinical benefits in a variety of different cancers; however, a large fraction of patients encounter resistance. Identifying novel targets that can improve T cell functionality can therefore broaden the potential of cancer immunotherapy. We developed methods for discovering such targets using CRISPR gene editing technology. First, we created a hybrid genetic screening system where Sleeping Beauty (SB) transposons and single guide RNA cassettes are nested in an adeno-associated virus (AAV) to enable in vivo AAV-SB-CRISPR screens for membrane protein targets in CD8+ T cells in mouse models of glioblastoma. Second, we developed …

The City Of Gods And Fortune: An Architectural And Urban History Of Daulatabad, Ca. 13th–15th Centuries, Mohit Manohar Apr 2022

The City Of Gods And Fortune: An Architectural And Urban History Of Daulatabad, Ca. 13th–15th Centuries, Mohit Manohar

Yale Graduate School of Arts and Sciences Dissertations

The fortified city of Daulatabad in Deccan India was of comparable size and prestige to Delhi between the thirteenth and fifteenth centuries. Daulatabad was situated on important pilgrimage and mercantile routes and attracted immigrants from various parts of the world. Due to its significance and strategic location, political powers from northern and southern India—practicing both Hinduism and Islam—fought fierce battles over the city. Several of them made it their capital. Despite its importance, Daulatabad is often treated as a footnote to Delhi, and its rich architecture and urban layout have not been art historically examined. The City of Gods and …

Exploring The Regulation Of Transcriptional Noise In Nf-Κb-Inducible Genes Across Chromatin Environments, Margaret Elise Bullock Apr 2022

Exploring The Regulation Of Transcriptional Noise In Nf-Κb-Inducible Genes Across Chromatin Environments, Margaret Elise Bullock

Yale Graduate School of Arts and Sciences Dissertations

There is a significant amount of cell-to-cell heterogeneity inherent in gene expression. One source of this heterogeneity in eukaryotes is transcriptional bursting, in which a gene promoter infrequently transitions from an inactive state to an active state, producing bursts of transcripts. Cell to cell variations lead to phenotypic differences downstream, which are implicated in immunological function. One model often used to study transcriptional bursting and its phenotypic consequences is human immunodeficiency virus (HIV). The HIV provirus integrates into the host genome, and in a subset of genomic locations, remains silent, or latent, until a perturbation stochastically reactivates viral transcription. Work …

Cell- And Extracellular Matrix-Based Approaches To Investigate Diabetic Fibroblasts And Improve Wound Healing, Hao Xing Apr 2022

Cell- And Extracellular Matrix-Based Approaches To Investigate Diabetic Fibroblasts And Improve Wound Healing, Hao Xing

Yale Graduate School of Arts and Sciences Dissertations

Chronic wounds are a major complication associated with diabetes. Often presented as foot ulcers, diabetic chronic wounds have a 5-7% prevalence among patients and can lead to serious consequences such as sepsis and amputation. Despite the devastating impact of such complications on patients’ health, current clinical interventions have limited efficacy, in part, due to 1) a limited understanding of the underlying cellular mechanism and 2) the lack of effective engineering solutions that can improve therapy. This thesis addresses these two issues by first investigating dysfunctions and altered molecular mechanisms in diabetic fibroblasts and then creating a novel, decellularized biomaterial enriched …

Transcriptomic And Cellular Reorganization Of The Human Prefrontal Cortex, Shaojie Ma Apr 2022

Transcriptomic And Cellular Reorganization Of The Human Prefrontal Cortex, Shaojie Ma

Yale Graduate School of Arts and Sciences Dissertations

The expansion and evolutionary specializations of the cerebral cortex, and especially the prefrontal cortex (PFC), are thought to underlie the rich and complex nature of primate and human cognition. The PFC is larger and anatomically more complex in anthropoid primates compared to other analyzed mammals, covering the entire dorsolateral two-thirds of the frontal lobe with a well-defined granular layer 4. The granular dorsolateral PFC (dlPFC) exhibits a broad connectivity with other brain regions. In this setting, dysfunction of the dlPFC also has been implicated in the etiology of many neuropsychiatric disorders. Accordingly, nonhuman primates have been used as model species …

Physical Activity And Sedentary Behavior Of Chinese Immigrants In The United States With Prior Gestational Diabetes Mellitus, Shuyuan Huang Apr 2022

Physical Activity And Sedentary Behavior Of Chinese Immigrants In The United States With Prior Gestational Diabetes Mellitus, Shuyuan Huang

Yale Graduate School of Arts and Sciences Dissertations

Gestational Diabetes Mellitus (GDM) is one of the most common complications during pregnancy with short- and long-term consequences for mothers and children. In the long term, women with prior GDM have a ten-fold risk of progressing to type 2 diabetes (T2D) compared to those without prior GDM. Chinese immigrants in the US are disproportionately affected by GDM and T2D. Physical activity (PA) and sedentary behavior (SB) are two modifiable behaviors to prevent T2D. The aims of this dissertation study were: 1) to describe the patterns of objectively measured PA and SB among Chinese immigrants in the US with prior GDM, …

Biogeochemical And Hydrologic Dynamics In Urban Watersheds: Dissolved Organic Matter Quantity And Quality Changes Across An Urbanization Gradient During Baseflow And Stormflow Conditions In Temperate River Networks, Lisa Christina Weber Apr 2022

Biogeochemical And Hydrologic Dynamics In Urban Watersheds: Dissolved Organic Matter Quantity And Quality Changes Across An Urbanization Gradient During Baseflow And Stormflow Conditions In Temperate River Networks, Lisa Christina Weber

Yale Graduate School of Arts and Sciences Dissertations

Dissolved organic matter (DOM) is a pivotal variable in aquatic ecosystems that can influence multiple factors, including pH, light penetration, stream metabolism, contaminant mobility, and water-treatment efficiency. Past studies on headwaters during baseflow have shown that urbanization is leading to DOM compositional changes; however, more research is needed across a range of stream orders with various upstream land influences, including urban point and nonpoint sources, during baseflow and stormflow to better understand urban DOM dynamics. Urban DOM sources can include leaky septic/sewer systems, treated wastewater effluent, and stormwater runoff. This dissertation examined changes in dissolved organic matter quantity and quality …

The Brain Bases Of Adaptive And Effortful Goal Pursuit, Lauren M. Patrick Apr 2022

The Brain Bases Of Adaptive And Effortful Goal Pursuit, Lauren M. Patrick

Yale Graduate School of Arts and Sciences Dissertations

Effortful goal pursuit is a complex process relying on the widespread engagement of a distributed set of large-scale brain systems. To date, investigations of the neural mechanisms underlying effortful goal pursuit have primarily focused on cortico-striatal regions of interest, leaving the role of large-scale networks unclear. To address this gap in our understanding, Chapter 1 provides an overview of the current state of knowledge of the brain bases of goal pursuit, examining the circuits and networks implicated, the role of effort costs, persistence and uncertainty, and the underlying structure that may support observed functional patterns. Chapters 2 through 4 report …

The Dead Receptor Paradox: Insights Into Receptor Tyrosine Kinases With Intracellular Pseudokinase Domains, Joshua B. Sheetz Apr 2022

The Dead Receptor Paradox: Insights Into Receptor Tyrosine Kinases With Intracellular Pseudokinase Domains, Joshua B. Sheetz

Yale Graduate School of Arts and Sciences Dissertations

Receptor tyrosine kinases, or RTKs, are key transducers of cellular signals in metazoans. All RTKs utilize a common architecture—an extracellular ligand binding region, a single-pass transmembrane helix, and an intracellular kinase domain—to control diverse biological processes from cellular metabolism to migration. Our understanding of how most receptors relay signals, however, remains incomplete. A particular puzzle is the collection of ~10% of RTKs that lack catalytic activity in their intracellular kinase homology domains, owing to altered amino acid residues thought necessary for phosphorylation. These so-called pseudokinases are highly evolutionarily conserved and are mutated, overexpressed, or otherwise dysregulated in certain cancers or …

The Mother Of Soviet Documentary: Esfir Shub In Compilation Film And Beyond, 1927-1937, Anastasia Kostina Apr 2022

The Mother Of Soviet Documentary: Esfir Shub In Compilation Film And Beyond, 1927-1937, Anastasia Kostina

Yale Graduate School of Arts and Sciences Dissertations

This dissertation explores the life and filmmaking career of the Soviet Union’s first – and arguably most important – female documentarian, Esfir Shub. The focus is on the first ten years of Shub’s directorial track, 1927-1937, during which she tirelessly pushed the boundaries of the documentary mode. Combining visual analysis and in-depth archival research with feminist historiography, the dissertation offers a critical reassessment of Shub’s directorial career and investigates the relationship between politics, aesthetics, and gender during documentary cinema’s nascent phase. The chapters of this dissertation are organized chronologically and are centered on the production context, form, and structure of …

Riboswitches As Versatile Scaffolds For Ligand Recognition And As Tools For Drug Discovery, Harini Sadeeshkumar Apr 2022

Riboswitches As Versatile Scaffolds For Ligand Recognition And As Tools For Drug Discovery, Harini Sadeeshkumar

Yale Graduate School of Arts and Sciences Dissertations

Riboswitches are highly structured, noncoding RNAs that bind specific ligands to regulate gene expression. To date, over fifty riboswitch classes have been validated to control fundamental biological processes and recognize various coenzymes, nucleotides, signaling molecules, ions, and other important ligands. As described in Chapter 1, careful study of these various riboswitches reveals an incredible diversity in their structural and biochemical characteristics as well as their function. Herein is detailed the efforts to validate long-standing orphan riboswitch classes involved in essential cellular functions such as maintaining nucleotide pools, managing ion toxicity, osmoregulation, and ATP production.The ykkC family of riboswitches are a …

Spirit Disfigured: The Persistence Of Freedom In The Modernist Novel, Jensen Suther Apr 2022

Spirit Disfigured: The Persistence Of Freedom In The Modernist Novel, Jensen Suther

Yale Graduate School of Arts and Sciences Dissertations

The modernist novel has often been read as an apolitical expression of dissatisfaction with bourgeois modernity. From Kafka to Beckett, the modernists are taken to champion a transcendent condition beyond the straitjacket of society, body, and self. Against this interpretive tradition, my dissertation draws on recent work in philosophy on conceptuality and affect as well as animality and social recognition to develop a new account of the politics of form in modernist fiction. First, the project shows that the idea of a free, self-determining subjectivity is not—as has often been argued—defeated in or left behind by the modernist novel. Rather, …

‘I Will Sing Of Love And Justice’: Jewish Responses To The Theological Roots Of Contemporary Virtue Ethics, Sarah V. Zager Apr 2022

‘I Will Sing Of Love And Justice’: Jewish Responses To The Theological Roots Of Contemporary Virtue Ethics, Sarah V. Zager

Yale Graduate School of Arts and Sciences Dissertations

This dissertation puts Jewish philosophy into conversation with contemporary ethical theory in order to develop a novel account of the relationship between moral rules and character development. I begin by showing that anti-Jewish rhetoric that criticized Judaism as overly concerned with rule-following has contributed significantly to the prevailing assumption that virtue ethics and deontology are two mutually exclusive ways to understand ethics. I then use Maimonides, Moses Mendelssohn, and the nineteenth-century Musar thinkers Israel Salanter and Simḥah Zissel Ziv as case studies to show that Jewish thought combines virtue ethics and deontology in ways that contemporary ethical theories have ignored. …

Three Essays On Racialized Disaster And Grassroots Resistance In U.S. Politics, Gwen Prowse Apr 2022

Three Essays On Racialized Disaster And Grassroots Resistance In U.S. Politics, Gwen Prowse

Yale Graduate School of Arts and Sciences Dissertations

In this three-paper dissertation, I examine the conditions under which social policy failures give rise to local grassroots political projects designed to meet the immediate needs of citizens in the short term and result in the creation of durable regional networks, fundraising strategies, and organizing methodologies in the long term. This project challenges the prevailing view in political science that national, federated organizations are the primary agents in mass politics by establishing subnational grassroots organizations’ pivotal role in political transformation. In the first paper in the dissertation, “Who knows better than the suffers themselves”: Theorizing Racialized Disaster in U.S Politics, …

Manipulating Neural Dynamics To Tune Motion Computation In Drosophila, Aneysis De Las Mercedes Gonzalez Apr 2022

Manipulating Neural Dynamics To Tune Motion Computation In Drosophila, Aneysis De Las Mercedes Gonzalez

Yale Graduate School of Arts and Sciences Dissertations

Virtually every neuron integrates inputs from excitatory and inhibitory presynaptic cells toproduce its output response. Despite this, it remains poorly understood how the dynamics of these inputs influence the neuron’s output. This is in part due to the difficulty of manipulating neural response dynamics with high specificity. Previous studies have used temperature and pharmacology to alter circuit dynamics (Arenz et al., 2017; Long and Fee, 2008; Suver et al., 2012; Tang et al., 2010), but these methods affect entire circuits, making it difficult to investigate how the dynamics of single excitatory and inhibitory input neurons drive computation. In this study, …

Towards Tumor Cell Specific Proteolysis Targeting Chimeras: Identification Of Oncogenic Krasg12c, Dcps, And Mage-A3 Degraders, Michael Joseph Bond

Yale Graduate School of Arts and Sciences Dissertations

Targeted Protein Degradation (TPD) is a nascent, rapidly evolving field in which cellular proteolysis pathways are co-opted to induce degradation of disease-causing proteins. PROteolysis TArgeting Chimeras (PROTACs) are heterobifunctional small molecules that recruit an E3 ubiquitin ligase to induce protein degradation. This pioneering technology has paved the way for other bifunctional modalities, like lysosome targeting chimeras (LYTACs) and autophagy targeting compounds (AUTAC/ATTEC), as well as monovalent “glue” degraders, and has drastically changed the drug discovery landscape. In Chapter 1 I review important PROTAC discovery milestones and provide an outlook on the future of PROTAC design. After a general introduction I …

Imaging Cholinergic And Dopaminergic Systems In Cigarette Smoking And Withdrawal, Katina Constantina Calakos Apr 2022

Imaging Cholinergic And Dopaminergic Systems In Cigarette Smoking And Withdrawal, Katina Constantina Calakos

Yale Graduate School of Arts and Sciences Dissertations

Tobacco smoking continues to be a leading cause of preventable disease and death. Individuals face challenges in quitting smoking due to negative experiences in early abstinence such as changes in mood and cognition, as well as the onset of cigarette craving, irritability, and other adverse withdrawal symptoms. Elucidation of neural systems involved in tobacco use and withdrawal may help predict cessation outcomes. The cholinergic and dopaminergic systems of the brain are involved in the reinforcing properties of cigarette smoking. Animal studies demonstrate that chronic nicotine exposure induces changes in beta2-subunit containing nicotinic acetylcholine receptor (beta2*-nAChR) expression and dopamine responsivity to …

Measuring The Knot Of Non-Hermitian Degeneracies And Non-Abelian Braids, Parker Alexander Henry Apr 2022

Measuring The Knot Of Non-Hermitian Degeneracies And Non-Abelian Braids, Parker Alexander Henry

Yale Graduate School of Arts and Sciences Dissertations

There has been much interest in physical systems that can be described as linear dynamical systems which incorporate gain, loss, and non-reciprocity. Such systems can serve as noveldevices in sensing and control applications. They can be realized in any physical domain, including optics, acoustics, electronics, and optomechanics. Systems that incorporate gain, loss, and non-reciprocity are known as “non-Hermitian,” and are distinguished from Hermitian systems by their complex eigenvalues, mode nonorthogonality, and a class of degeneracy known as an exceptional point, for which the dynamical matrix H is nondiagonalizable. Spectral flow presents another distinction between non-Hermitian and Hermitian systems. Spectral flow …

Extracellular Elastin Assembly And Vascular Hyperproliferation: Connections For Treatment And Tissue Engineering, Matthew Ellis Apr 2022

Extracellular Elastin Assembly And Vascular Hyperproliferation: Connections For Treatment And Tissue Engineering, Matthew Ellis

Yale Graduate School of Arts and Sciences Dissertations

Elastin is the load-bearing extracellular matrix protein complex that endows the aorta with the recoil necessary to propagate blood to the peripheral circulation following systolic ejection from the heart. The assembly of the elastin complex occurs early in perinatal development and degrades over the course of a human lifetime, leading to arterial stiffening and elevated blood pressure. Although this complex assembly process occurs seamlessly in vivo, it has been a large obstacle in the field to replicate this process in vitro, hampering efforts to engineer elastin-rich grafts for transplantation and to study and develop curative treatments for elastin-associated pathologies. Herein, …

Studying Disease Dynamics With Manifold Learning, Manik Razdan Kuchroo Apr 2022

Studying Disease Dynamics With Manifold Learning, Manik Razdan Kuchroo

Yale Graduate School of Arts and Sciences Dissertations

In an effort to computationally predict causal genetic networks and derive biological pathways empirically, biomedical scientists have begun to design increasingly complicated single cell experiments. A single study can now sequence millions of cells from hundreds of patient samples across different chronological timepoints or stages of disease progression with multiple measurement modalities. None of these additional complexities, however, are adequately addressed by the current state-of-the-art computational tools. Current machine learning techniques ignore these valuable sources of information by either downsampling the number of cells to a computationally tractable number or discarding experimental information, like stage of disease, modality or timepoint, …

Discovery Of Selective Binding Molecules For The Pseudokinase Domain Of Janus Kinase 2, Maria-Elena Liosi Apr 2022

Discovery Of Selective Binding Molecules For The Pseudokinase Domain Of Janus Kinase 2, Maria-Elena Liosi

Yale Graduate School of Arts and Sciences Dissertations

Janus Kinase 2 (JAK2) is a nonreceptor tyrosine kinase that plays an important role in the regulation of hematopoiesis through the JAK-STAT pathway. JAK2 is comprised of seven Janus Homology (JH) domains, including a C-terminal kinase domain (JH1) responsible for the catalytic activity, and an adjacent pseudokinase domain (JH2). The pseudokinase domain adopts a prototypical protein-kinase fold and can bind ATP, but it lacks critical residues for phosphorylation catalysis. Its primary role is to regulate the function of the JH1 domain, and according to recent insights, it also plays critical role in cytokine receptor dimerization. V617F, the most frequently occurring …

Combining High Performance Mass Spectrometry And Cryogenic Ion Spectroscopy For Structure Determinations Of Exotic Molecules And Reaction Intermediates, Evan Hunt Perez

Yale Graduate School of Arts and Sciences Dissertations

High-performance mass spectrometry is a staple for analytical chemistry in a vast number of industries and academic settings. In recent years, gas-phase analysis of highly reactive species has become prevalent, as isolation of these intermediates provides fundamental chemical insight. Collision-induced dissociation (CID) is a technique that is leveraged to generate these reactive species. Paired with mass spectrometry, cryogenic ion spectroscopy provides sharp vibrational spectra that allows for accurate structural comparison to electronic structure calculations. The combination of these two techniques enables the structure determination of a new class of ions and complexes. In this dissertation, the details of the integration …

Co-Option Of Alveolar Macrophage Homeostatic Metabolic Networks In Lung Adenocarcinoma, Alexandra Kuhlmann Apr 2022

Co-Option Of Alveolar Macrophage Homeostatic Metabolic Networks In Lung Adenocarcinoma, Alexandra Kuhlmann

Yale Graduate School of Arts and Sciences Dissertations

Cancer, fundamentally a disease of deregulated tissue homeostasis, substantially alters the composition of the surrounding tumor microenvironment (TME). The metabolic demands for rapid cellular growth and proliferation result in abnormally high rates of glucose and amino acid consumption in cancer cells. We propose a model in which nutrient competition creates a metabolic checkpoint engendering a suppressive TME. Failure to acquire adequate nutrients is compounded by the accumulation of nutritionally—and therefore immunologically—permissive immune cells. In Chapter 2, using a genetically induced mouse model of lung adenocarcinoma, we observed a striking expansion in resident alveolar macrophages (AM). AM accumulation was dependent upon …

Keep It Barbershop: Stylistic Preservation And Whiteness In The Barbershop Harmony Society, Clifton Boyd Apr 2022

Keep It Barbershop: Stylistic Preservation And Whiteness In The Barbershop Harmony Society, Clifton Boyd

Yale Graduate School of Arts and Sciences Dissertations

This dissertation examines the entanglement of music-theoretical practices and sociopolitical values in the Barbershop Harmony Society (BHS), a fraternal singing organization with over 15,000 members and 600 chapters in the U.S. and Canada, as well as several affiliate barbershop societies across Europe. Since its founding in 1938, the BHS has had the explicit aim of preserving the barbershop style, a four-part, a cappella singing tradition popularized in the late nineteenth century and known for its ringing harmonies and camaraderie. Yet this bonhomie had its limits: by the early 1960s, at the height of the civil rights movement, the correlation between …

Comprehensive Identification And Characterization Of Cajal Body Components, Dahyana Arias Escayola Apr 2022

Comprehensive Identification And Characterization Of Cajal Body Components, Dahyana Arias Escayola

Yale Graduate School of Arts and Sciences Dissertations

Each cell’s nucleus is a safe harbor for the genome (DNA), ensuring the integrity of all of the genes that contribute to development and health of an organism. What’s more, the 3-dimensional (3D) organization of the cell nucleus regulates how genes are expressed to give each cell its unique characteristics. In addition to chromosomes, the nucleus contains nuclear bodies, which are functionally distinct yet membraneless compartments that likely form through liquid-liquid phase separation (LLPS). Nuclear bodies concentrate specific proteins and RNAs on distinct chromosomal DNA regions to regulate gene expression. One of these nuclear bodies, the Cajal Body (CB), is …

Now I Walk On Foreign Soil: Settler Colonialism In Argentina’S Southern Borderlands, 1867-1899, Hannah Greenwald Apr 2022

Now I Walk On Foreign Soil: Settler Colonialism In Argentina’S Southern Borderlands, 1867-1899, Hannah Greenwald

Yale Graduate School of Arts and Sciences Dissertations

“Now I Walk On Foreign Soil: Settler Colonialism in Argentina’s Southern Borderlands, 1867-1899” examines the relationship between military violence, Indigenous resistance, and settler colonial state formation in Argentina. This dissertation charts how during the so-called “Conquest of the Desert” (1879-1885), formerly autonomous Indigenous peoples in the pampas and Patagonia were subjugated to Argentine state rule through military violence, and discursively erased from Argentina’s national community. Employing the methodologies of microhistory and ethnohistory, alongside the frameworks of settler colonial theory and genocide studies, it examines the intertwined forms of military and nonmilitary violence intended to physically and ideologically eradicate Indigenous people …
