Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller Dec 2020

Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller

Biology ETDs

The loss of large carnivores is fundamentally restructuring modern mammal communities. However, large carnivore removal is not exclusively a modern trend. The Pleistocene Megafaunal Extinction (PME) resulted in a near-eradication of hyper-carnivorous felids such as saber-toothed cats. However, it is unclear if smaller surviving meso-felids began to infill this ecological vacuum post-PME. I apply Ecological Niche Modeling (ENM) to test evaluate whether surviving felids filled in vacant niches post-extinction, and hypothesize that they ought to have shown increased niche-overlap patterns with mega-felids post-extinction. I model species’ fundamental niches using a multi-temporal approach, and develop a novel test to model realized …


Impact Of Cd82 Expression On Acute Myeloid Leukemia Chemosensitivity And Quiescence, Muskan Floren Dec 2020

Impact Of Cd82 Expression On Acute Myeloid Leukemia Chemosensitivity And Quiescence, Muskan Floren

Biomedical Sciences ETDs

Acute Myeloid Leukemia (AML) patients respond favorably to induction chemotherapy, however, long-term outcomes remain poor due to a high rate of chemoresistance and bone marrow minimal residual disease. To improve long-term patient outcomes, it’s critical to identify regulators of chemotherapy resistance in AML and develop therapies that are directed towards bone marrow resident AML cells. In Chapter 2, we uncover the impact of CD82 expression in AML response to chemotherapeutic treatment and the contribution of Protein Kinase C α (PKCα) and β1 integrin signaling in promoting p38 MAPK activation to support CD82-mediated AML cell survival. In Chapter 3, we …


Understanding The Role Of Atom Trapping In The Evolution Of Hydrocarbon Transformation Catalyst Morphology, Griffin Alexander Canning Dec 2020

Understanding The Role Of Atom Trapping In The Evolution Of Hydrocarbon Transformation Catalyst Morphology, Griffin Alexander Canning

Chemistry and Chemical Biology ETDs

Converting alkanes to other, more chemically and economically valuable molecules requires catalysts that can survive elevated temperatures and highly reducing environments. These environments can cause many metal-nanoparticle based catalysts to sinter rapidly, causing a loss of activity. They must also tolerate the coke formation, as well, since coke can restrict access to active sites by gas phase molecules, thus lowering catalytic activity. While there are routes to improve both the sinter and coke resistance of catalysts, an alternative strategy is to develop a protocol for regenerating the activity of the catalyst in question when coke formation or sintering becomes problematic. …

Biology ETDs

Ant-mimicking spiders in the subfamily Castianeirinae have had a number of taxonomic revisions and species descriptions. Despite these advancements, more species exist await formal scientific description and little scientific progress has been made in terms of reconstructing their evolutionary histories. This study 1) describes a new species Castianeira reiskind sp. n. from cloud forests in Nicaragua; and 2) presents a first look of the Australian Castianeirinae taxa in a phylogenetic framework. This analysis is used to explore the origins of Hymenoptera mimicry in this group, test the monophyly of this subfamily compared to the Corinninae and to test the current …


The Effects Of Glycosylation On Immunogenicity And Replication Of Emerging Viral Pathogens, Elizabeth Carvosso Clarke Dec 2020

The Effects Of Glycosylation On Immunogenicity And Replication Of Emerging Viral Pathogens, Elizabeth Carvosso Clarke

Biomedical Sciences ETDs

For filoviruses, a family of hemorrhagic fever viruses, the main antigen for vaccines in development is the glycosylated glycoprotein GP1,2. How the glycosylation of GP1,2 differs when the protein is produced in different cell lines is unclear. We showed significant differences in the types of glycans conferred onto filovirus GP1,2s in produced in mammalian-origin and insect-origin cell lines. Mammalian-derived filovirus GP1,2s have diverse N-linked glycans and extensive O-linked glycans, whereas insect-derived filovirus GP1,2s have N-linked glycans that are primarily paucimannose type and have no observable O-linked glycans. We then showed that differences in glycosylation impacted how immunogenic the proteins were …


Ibram X. Kendi's How To Be An Antiracist, Quatez Scott Dec 2020

Ibram X. Kendi's How To Be An Antiracist, Quatez Scott

Intersections: Critical Issues in Education

This book review of Ibram X. Kendi’s How to Be an Antiracist (2019) addresses the importance of exploring race relations in the U.S. from a framework that focuses on racial policies. Commonly referred to as “systemic racism” and “institutional racism”, racist policies maintain racial inequities. Antiracists aim to eliminate those racial policies. Kendi’s ability to address these issues head on with deeply researched historical narratives brings light to the ways racial policies are reinforced, which reproduce racist ideas. This book drives straight to the heart of racial challenges and takes a new approach at examining how and why humans should …

Pathology Research and Scholarship

Although B-cell acute lymphoblastic leukemia (B-ALL) is the most common malignancy in children and while highly curable, it remains a leading cause of cancer-related mortality. The outgrowth of tumor subclones carrying mutations in genes responsible for resistance to therapy has led to a Darwinian model of clonal selection. Previous work has indicated that alterations in the epigenome might contribute to clonal selection, yet the extent to which the chromatin state is altered under the selective pressures of therapy is unknown. To address this, we performed chromatin immunoprecipitation, gene expression analysis, and enhanced reduced representation bisulfite sequencing on a cohort of …


Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya Dec 2020

Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya

Biomedical Sciences ETDs

Dectin-1A is a C-type Lectin innate immunoreceptor that recognizes β-(1,3)-glucan, a structural component of Candida species cell walls. Dectin-1 has eight alternative splice isoforms including, A and B. Innate immunocytes can express one or both isoforms, but neither their relative responsiveness to β-glucan nor the potential for inter-isoform signaling cross-talk is well understood. In this study, we determine how the different structures of soluble β-glucans affect both isoforms and unravel how differences in glucan structure impact the earliest events in Dectin-1 signaling. Using quantitative microscopy techniques, we explored the role of glucan structure on Dectin-1A oligomerization, which is thought to …

Introduction To Neutrosophic Genetics, Florentin Smarandache Dec 2020

Introduction To Neutrosophic Genetics, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Neutrosophic Genetics is the study of genetics using neutrosophic logic, set, probability, statistics, measure and other neutrosophic tools and procedures. In this paper, based on the Neutrosophic Theory of Evolution (that includes degrees of Evolution, Neutrality (or Indeterminacy), and Involution) – as extension of Darwin’s Theory of Evolution, we show the applicability of neutrosophy in genetics, and we present within the frame of neutrosophic genetics the following concepts: neutrosophic mutation, neutrosophic speciation, and neutrosophic coevolution.

Atom Trapping And Its Role On The Nucleation & Growth Of Platinum Nanoparticles, Deepak Kunwar Nov 2020

Atom Trapping And Its Role On The Nucleation & Growth Of Platinum Nanoparticles, Deepak Kunwar

Chemistry and Chemical Biology ETDs

Diesel oxidation catalysts deactivate due to Pt sintering, a major problem in automotive industries. To make sure they operate effectively throughout the lifetime of the vehicle, automotive industries are putting an excessive amount of Pt. There is a need to develop a catalyst that serves long term performance with minimal use of Pt. Jones et al.1 demonstrated that ceria traps Pt atoms. His work generated some logical and valid questions such as what is the mechanism for the formation of anomalously large Pt particles? What is the upper limit of Pt metal loading in the form of single atoms …


Radial Basis Densities And The Density Functional-Based Atom-In-Molecule: Designing Charge-Transfer Potentials, Godwin Amo-Kwao Nov 2020

Radial Basis Densities And The Density Functional-Based Atom-In-Molecule: Designing Charge-Transfer Potentials, Godwin Amo-Kwao

Nanoscience and Microsystems ETDs

Classical potentials that are capable of describing charge transfer and charge polarization in complex systems are of central importance for classical atomistic simulation of biomolecules and materials. Current potentials—regardless of the system—do not generalize well, and, with the exception of highly-specialized empirical potentials tuned for specific systems, cannot describe chemical bond formation and breaking. The charge-transfer embedded atom method (CT-EAM), a formal, DFT-based extension to the original EAM for metals, has been developed to address these issues by modeling charge distortion and charge transfer in interacting systems using pseudoatom building blocks instead of the electron densities of isolated atoms. CT-EAM …


Evolution Of Brain-Wide Activity In The Awake Behaving Mouse After Acute Fear By Longitudinal Manganese-Enhanced Mri, Taylor W. Uselman, Daniel R. Barto, Russell E. Jacobs, Elaine L. Bearer Nov 2020

Evolution Of Brain-Wide Activity In The Awake Behaving Mouse After Acute Fear By Longitudinal Manganese-Enhanced Mri, Taylor W. Uselman, Daniel R. Barto, Russell E. Jacobs, Elaine L. Bearer

Pathology Research and Scholarship

Life threatening fear after a single exposure evolves in a subset of vulnerable individuals to anxiety, which may persist for their lifetime. Yet neither the whole brain's response to innate acute fear nor how brain activity evolves over time is known. Sustained neuronal activity may be a factor in the development of a persistent fear response. We couple two experimental protocols to provoke acute fear leading to prolonged fear: Predator stress (PS), a naturalistic approach to induce fear in rodents; and Serotonin transporter knockout mouse (SERT-KO) that responds to PS with sustained defensive behavior. Behavior was monitored before, during and …


Chad: Human Fertility, Crop Production And Changing Weather Patterns, Jake Organ Nov 2020

Chad: Human Fertility, Crop Production And Changing Weather Patterns, Jake Organ

Economics ETDs

The subject of this dissertation is the effect of changing weather patterns on human fertility in Chad, Sahelian Africa. There is a body of literature on the effect of extreme weather events-usually associated with large-scale mortality-and human fertility. However, there is less of a body of literature on the effects of less extreme changing weather patterns and human fertility. Chad has known substantial warming since the late 1960s, hence I use rising heat as a proxy for changing weather patterns. Using GIS-coded fertility and weather data, I look for correlations between the birth rate and the number of days in …

From Wave Propagation To Spin Dynamics: Mathematical And Computational Aspects, Oleksii Beznosov Nov 2020

From Wave Propagation To Spin Dynamics: Mathematical And Computational Aspects, Oleksii Beznosov

Mathematics & Statistics ETDs

In this work we concentrate on two separate topics which pose certain numerical challenges. The first topic is the spin dynamics of electrons in high-energy circular accelerators. We introduce a stochastic differential equation framework to study spin depolarization and spin equilibrium. This framework allows the mathematical study of known equations and new equations modelling the spin distribution of an electron bunch. A spin distribution is governed by a so-called Bloch equation, which is a linear Fokker-Planck type PDE, in general posed in six dimensions. We propose three approaches to approximate solutions, using analytical and modern numerical techniques. We also present …


Inoculum Potential Of Pinus Edulis-Associated Ectomycorrhizal Fungi Across A Forest Extirpation Chronosequence, Annie M. Montes Nov 2020

Inoculum Potential Of Pinus Edulis-Associated Ectomycorrhizal Fungi Across A Forest Extirpation Chronosequence, Annie M. Montes

Biology ETDs

Few studies have examined inoculum potential of ectomycorrhizal fungi (EMF) in the absence of plant hosts, yet persistence of these fungi may be paramount to resilience of Pinus edulis and other mycorrhizal plant species. We conducted a study in which seven sites were selected in northwestern New Mexico with known dates of P. edulis extirpation and a lack of regeneration. Age classes included: two sites extirpated 10-20 years ago, two extirpated 55-65 years ago, two extirpated 500+ years ago, and one extirpated 11,000+ years ago. At each site, two plots were paired: an extirpated plot and the nearest live adult …


Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook Nov 2020

Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook

Biology ETDs

Fungi perform several critical functions in the environment. Spatiotemporal distributions of fungal communities will mediate when and where these functions happen and how they vary across the landscape. I first explored tropical tree canopy fungal community variation at small spatial scales and documented near total turnover of fungi across sub-meter distances and among adjacent substrates. The second chapter analyzed fungal turnover over the course of three years, where community stability was driven primarily by abundant fungi. In the third chapter, I tested effects of the environment, including host plant and habitat, on canopy fungal communities and found only small effects, …


Gan Nanowire Laser For A Universal Atomic Force Microscope Probe: A Computational And Feasibility Study, Neal Wostbrock Nov 2020

Gan Nanowire Laser For A Universal Atomic Force Microscope Probe: A Computational And Feasibility Study, Neal Wostbrock

Nanoscience and Microsystems ETDs

This thesis attempts to establish the groundwork for integrating a GaN nanowire into an AFM probe resulting in a universal atomic force microscope probe. Previous studies have shown GaN nanowires have stable mechanical properties, can be fabricated at scale with high aspect ratios and very smooth side walls, and have intrinsic lasing capabilities; however, mechanical and lasing capabilities have not yet been integrated into a single AFM probe. Here, we develop and analyze a suspended waveguide optical pumping concept that can be fabricated and applied to an AFM probe cantilever, unlocking full potential of GaN’s optical and mechanical properties as …

Mucosal Immune System Of African Lungfish, Ryan D. Heimroth Nov 2020

Mucosal Immune System Of African Lungfish, Ryan D. Heimroth

Biology ETDs

Conquering land was an apex moment in the evolution of vertebrates. Physiologically, the first vertebrates to transition to life on land had to adapt in order to survive in an oxygen-rich environment where gravitational forces and limited water prevailed. Several extant vertebrates including anurans and lungfish, survive droughts by undergoing aestivation. Unfavorable environmental conditions trigger lungfish to aestivate. Aestivation is a process of metabolic torpor wherein the fish will encase itself in a mucus cocoon and not move until favorable environmental conditions (food and water) are reintroduced. Aestivation can be reproduced in laboratory settings and, thus, lungfish can be used …
