3d Vessel-Wall Virtual Histology Of Whole-Body Perfused Mice Using A Novel Heavy Element Stain, P. Joy Dunmore-Buyze, Charmainne Cruje, Zengxuan Nong, Jason J. Lee, John A. Kiernan, J. Geoffrey Pickering, Maria Drangova

Medical Biophysics Publications

Virtual histology – utilizing high-resolution three-dimensional imaging – is becoming readily available. Micro-computed tomography (micro-CT) is widely available and is often coupled with x-ray attenuating histological stains that mark specific tissue components for 3D virtual histology. In this study we describe a new tri-element x-ray attenuating stain and perfusion protocol that provides micro-CT contrast of the entire vasculature of an intact mouse. The stain – derived from an established histology stain (Verhoeff’s) – is modified to enable perfusion through the vasculature; the attenuating elements of the stain are iodine, aluminum, and iron. After a 30-minute perfusion through the vasculature (10-minute …

A Macaque Connectome For Large-Scale Network Simulations In Thevirtualbrain, Kelly Shen, Gleb Bezgin, Michael Schirner, Petra Ritter, Stefan Everling, Anthony R. Mcintosh

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Models of large-scale brain networks that are informed by the underlying anatomical connectivity contribute to our understanding of the mapping between the structure of the brain and its dynamical function. Connectome-based modelling is a promising approach to a more comprehensive understanding of brain function across spatial and temporal scales, but it must be constrained by multi-scale empirical data from animal models. Here we describe the construction of a macaque (Macaca mulatta and Macaca fascicularis) connectome for whole-cortex simulations in TheVirtualBrain, an open-source simulation platform. We take advantage of available axonal tract-tracing datasets and enhance the existing …

Predator-Induced Fear Causes Ptsd-Like Changes In The Brains And Behaviour Of Wild Animals, Liana Y. Zanette, Emma C. Hobbs, Lauren E. Witterick, Scott A. Macdougall-Shackleton, Michael Clinchy

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s). Predator-induced fear is both, one of the most common stressors employed in animal model studies of post-traumatic stress disorder (PTSD), and a major focus of research in ecology. There has been a growing discourse between these disciplines but no direct empirical linkage. We endeavoured to provide this empirical linkage by conducting experiments drawing upon the strengths of both disciplines. Exposure to a natural cue of predator danger (predator vocalizations), had enduring effects of at least 7 days duration involving both, a heightened sensitivity to predator danger (indicative of an enduring memory of fear), and elevated neuronal …

Parsing The Effects Of Demography, Climate And Management On Recurrent Brucellosis Outbreaks In Elk, Gavin C. Cotterill, Paul C. Cross, Jerod A. Merkle, Jared D. Rogerson, Brandon M. Scurlock, Johan T. Du Toit

Wildland Resources Faculty Publications

1. Zoonotic pathogens can harm human health and well‐being directly or by impacting livestock. Pathogens that spillover from wildlife can also impair conservation efforts if humans perceive wildlife as pests. Brucellosis, caused by the bacterium Brucella abortus, circulates in elk and bison herds of the Greater Yellowstone Ecosystem and poses a risk to cattle and humans. Our goal was to understand the relative effects of climatic drivers, host demography and management control programmes on disease dynamics.
2. Using >20 years of serologic, demographic and environmental data on brucellosis in elk, we built stochastic compartmental models to assess the influences of climate forcing, …

Scaffolding Choice, Increasing Access: A Summer Initiative To Promote Middle School Students’ Book Reading, Lauren Capotosto

Reading Horizons: A Journal of Literacy and Language Arts

Middle schools often mandate summer reading as a means of stemming summer learning loss, but research suggests that many students do not read any books during the summer months. Limited book access and difficulties self-selecting books are two barriers that can impact students’ summer reading practices. To address these challenges, students in one Grade 7 classroom participated in an initiative designed to scaffold book choices prior to summer break and to increase students’ access to high-interest books. Compared to students in a randomly selected business-as-usual classroom, students who participated in the book scaffolding initiative were more likely to read at …

Use Of Aerial Imagery And Novel Experimental Design To Determine The Distribution Of Foliar Diseases On Soybean And Improve Efficiency Of Product Testing, Mckayla Patterson

Graduate Theses and Dissertations

Soybeans are grown on approximately 1.3 million ha in Arkansas generating an estimated $1.7 billion annually. Foliar diseases on soybean can result in economic losses. Growers spend significant time and money on disease scouting via crop consultants and often (subsequent) fungicide applications. Fungicide trials are often arranged in small plots designs. In these scenarios, spatial variability of foliar disease is minimized. While it is advantageous to minimize variance outside of treatment differences, another limitation with many small plot trials is ample disease pressure or having only lower severity. Within a commercial production field, soil types and disease severities vary. Logically, …

Understanding How The Effectors Hopd1 And Hopg1 From The Bacterial Pathogen Pseudomonas Syringae Pv. Tomato Dc3000 Target The Arabidopsis Thaliana Protein Atnhr2b To Cause Disease In Plants, Catalina Maria Rodriguez Puerto

Graduate Theses and Dissertations

The pathogenicity of Pseudomonas syringae is associated with the type III secretion system (T3SS), a complex of proteins assembled in the inner and outer bacterial membranes that traverses the plant cell wall to deliver bacterial proteins into the cytoplasm of plant cells. The effector proteins translocated into the plant cells are called Hops (Hypersensitive response and pathogenicity outer proteins). Bacterial effectors target plant immune proteins to suppress defense responses and enhance bacterial parasitism. The Arabidopsis thaliana nonhost resistance 2B (AtNHR2B), a recently identified immune protein, is degraded after inoculation with the adapted pathogen of Arabidopsis, P. syringae pv tomato DC3000 …

Growth Differentiation Factor 11 Locally Controls Anterior-Posterior Patterning Of The Axial Skeleton., Joonho Suh, Je-Hyun Eom, Na-Kyung Kim, Kyung Mi Woo, Jeong-Hwa Baek, Hyun-Mo Ryoo, Se-Jin Lee, Yun-Sil Lee

Faculty Research 2019

Growth and differentiation factor 11 (GDF11) is a transforming growth factor β family member that has been identified as the central player of anterior-posterior (A-P) axial skeletal patterning. Mice homozygous for Gdf11 deletion exhibit severe anterior homeotic transformations of the vertebrae and craniofacial defects. During early embryogenesis, Gdf11 is expressed predominantly in the primitive streak and tail bud regions, where new mesodermal cells arise. On the basis of this expression pattern of Gdf11 and the phenotype of Gdf11 mutant mice, it has been suggested that GDF11 acts to specify positional identity along the A-P axis either by local changes in …

Assessment Of Bones Deficient In Fibrillin-1 Microfibrils Reveals Pronounced Sex Differences., Lukas Altinbas, Nicole Bormann, Daniel Lehmann, Sarah Jeuthe, Dag Wulsten, Uwe Kornak, Peter N Robinson, Britt Wildemann, Georgios Kararigas

Faculty Research 2019

Defects in the extracellular matrix protein fibrillin-1 that perturb transforming growth factor beta (TGFβ) bioavailability lead to Marfan syndrome (MFS). MFS is an autosomal-dominant disorder, which is associated with connective tissue and skeletal defects, among others. To date, it is unclear how biological sex impacts the structural and functional properties of bone in MFS. The aim of this study was to investigate the effects of sex on bone microarchitecture and mechanical properties in mice with deficient fibrillin-1, a model of human MFS. Bones of 11-week-old male and female Fbn1^mgR/mgR mice were investigated. Three-dimensional micro-computed tomography of femora and vertebrae …

Laughing Back: A Phenomenological Study Of Disability Humor Using Culturally Responsive Methodologies, Kinda Abujbarah

Education (PhD) Dissertations

Historically, disabled people have not been viewed as innovators of humor because disability is associated with tragedy. My dissertation challenged the association of disability with tragedy by positioning disabled comedians as educators and ambassadors of disability rights. I reviewed the literature on disability and humor as well as disability oppression, which disability humor challenges. I used phenomenology as well as culturally responsive methodologies to examine what disabled comedians are achieving with their humor and what nondisabled audience members learned from attending their performances. Vygotsky’s sociocultural theory of learning was used to examine learning outcomes for audience members. I examined historical …

Of Water Jars And Women: A Re-Evaluation Of Fountain House Imagery On Late Archaic Black-Figure Hydriai, Christopher Askew

School of Art, Art History, and Design: Theses and Student Creative Work

From approximately 530 to 500 BCE, images of fountain houses became popular subjects on black-figure hydriai produced in or around ancient Athens. These scenes often involve groups of unidentified women gathering around a fountain spout, typically attached to an ornate architectural structure, in order to fill their water jars. Although isolated pottery sherds depicting these scenes have been discovered in Greece, approximately seventy-five of these scenes have been identified on Attic hydriai depicting such scenes were discovered in Etruscan tombs. Past scholarship has categorized these images either as genre scenes, which represent a domestic activity characteristic of everyday life, or …

Development And Testing Of A Control Strategy For Dynamic Cooling At Rack Level In Data Centers, Amrutha Valli Rachakonda

Mechanical and Aerospace Engineering Theses - Archive

Cooling is a critical part of data center’s infrastructure, and with ongoing demands in data processing and storage, thermal management issues are of great concern. Some imperative methods of removing heat are either using air or liquid (preferably water or refrigerant). When high power density modules are involved, liquid cooling addresses some of the problems faced by air cooling as liquid coolants have higher thermal capacitance. Also, in the case of multi-chip modules, a non-uniform heating due to multi-core generates hot-spots and increases temperature gradients across the module. A dynamic cold plate along with a self-regulated flow control device was …

Planning Practices For The Public Mental Health, Kaitlin A. Mcbride

Planning Theses - Archive

The rapid urbanization taking place in the 21st century poses its own unique set of public health concerns. In addition to changing lifestyles around the world, mental illness rates are higher in our cities. While the conversations surrounding public health usually focus on the physical, mental health has an equal impact on the overall wellbeing of individuals and populations. Just as the planning profession finds it crucial to be involved in efforts to improve the physical public health in cities, we must do the same for the public mental health. Like most professions, planning is guided by our theories. These …

Effect Of Substrate To Inoculum Ratio On Bioenergy Recovery From Food Waste, Yard Waste, And Biosolids By High Solids Anaerobic Digestion, Phillip J. Dixon, Sarina J. Ergas, James R. Mihelcic, Shakira R. Hobbs

Civil Engineering Faculty Publications

Residual biosolids from wastewater treatment facilities and the organic fraction of municipal solid waste (OFMSW), such as food and yard wastes (FW and YW), are difficult to manage due to increased waste generation and recent stringent regulations. This study investigated the effect of substrate to inoculum ratio (S/I) on biochemical transformation mechanisms and biomethane production during high solids anaerobic digestion of FW, YW, and biosolids. Biochemical methane potential (BMP) assays were set up under mesophilic conditions at S/I of 1.0, 2.0, and 3.0 g OFMSW total solids (TS)/g inoculum TS. BMP with the lowest S/I (1.0) produced the highest cumulative …

Individual Differences In Executive Function And Reappraisal: A Latent-Variable Analysis, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Cognitive reappraisal is an adaptive emotion regulation strategy that positively impacts various facets of adaptive functioning (e.g., interpersonal relations, subjective well-being). Although reappraisal implicates cognitive processing, a clear consensus concerning the cognitive underpinnings of reappraisal has not yet been reached. Therefore, we examined how executive function (EF)—i.e., three general-purpose control abilities comprising working memory, inhibition, and shifting—are associated with performance-based reappraisal ability and self-reported reappraisal frequency. Using a latent-variable approach, we found that the shared variance among EF tasks (i.e., common EF)—a general goal-management ability that facilitates the active maintenance of task goals—significantly predicted reappraisal ability, but not reappraisal frequency. …

Learning Robot Manipulation Tasks Via Observation, Michail Theofanidis

Computer Science and Engineering Dissertations - Archive

The coexistence of humans and robots has been the aspiration of many scientific endeavors in the past century. Most anthropomorphic or industrial robots are highly articulated and complex machines, which are designed to carry out tasks that often involve the manipulation of physical objects. Traditionally, robots learn how to perform such tasks with the aid of a human programmer or operator. In this regard, the human acts as a teacher who provides a demonstration of a task. From the data of the demonstration, the robot must learn a state-action mapping that accomplishes the task. This state-action mapping is often addressed …
