Investigation Of Photopolymer-Based Holographic Optical Elements For Solar Applications, Hoda Akbari

Doctoral

The aim of this research was to explore the potential of photopolymer Holographic Optical Elements (HOE) for use in the collection of light from a moving source, such as the sun, and its direction into a fixed detector/convertor for application in solar concentrators. In order to increase the acceptance angle and the wavelength range of operation of the holographic device, low spatial frequency holographic recording was explored. The challenge was to record high diffraction efficiency HOEs at this spatial frequency, since it requires a material with relatively fast monomer diffusion. The acrylamide-based photopolymer developed at the Centre for Industrial and …

Modeling Viscoelastic Behavior In Compact Bone Through A Distribution Of Collagen D-Spacing: A Finite Element Analysis, Christopher Ha

Master's Theses

Osteoporosis affects nearly 54 million people in the United States. The cost associated with treatment is estimated to be $19 billion per year and is expected to grow yearly. D-spacing is the staggering of collagen molecules found at the nanoscopic level. Previously thought to have a constant value, recent studies have found that D-spacing has a distribution of values throughout the tissue. As part of an ongoing effort in understanding the mechanisms that are affected by osteoporosis, a finite element model was developed to explore the effects of D-spacing distribution on the viscoelastic material properties of bone tissue. The goal …

King Penguins Can Detect Two Odours Associated With Conspecifics, Gregory B. Cunningham, Francesco Bonadonna

Biology Faculty/Staff Publications

Recent studies on olfaction in penguins have focused on their use of odours while foraging. It has been proposed for some seabirds that an olfactory landscape shaped by odours coming from feeding areas exists. Islands and colonies, however, may also contribute to the olfactory landscape and may act as an orienting map. To test sensitivities to a colony scent we studied whether King penguins (Aptenodytes patagonicus) could detect the smell of sand, feathers or feces by holding presentations beneath their beaks while they naturally slept on the beach. Penguins had a significantly greater response to the feathers and feces presentations …

The Organization And Structure Of The Governmental Relations Function In Community Colleges: A Case Study At Five Texas Community Colleges, Steven E. Johnson

Department of Educational Administration: Dissertations, Theses, and Student Research

Governmental relations, how institutions of higher education interact with appointed and elected governmental officials, has not been well defined or widely researched. This is especially the case at community colleges. Today, community colleges enroll half of all students in the United States in higher education and have become the largest sector of higher education in Texas. The need for community colleges to understand and to influence policy and funding decisions through governmental relations has intensified as Texas has faced pressure on state revenue as a result of two economic recessions over the past decade.

To understand how Texas community colleges …

Body Size Affects Individual Winter Foraging Strategies Of Thick-Billed Murres In The Bering Sea, Rachael Orben, Rosana Paredes, Daniel Roby, David Irons, Scott A. Shaffer

Faculty Publications, Biological Sciences

Foraging and migration often require different energetic and movement strategies. Though not readily apparent, constraints during one phase might influence the foraging strategies observed in another. For marine birds that fly and dive, body size constraints likely present a trade-off between foraging ability and migration as smaller bodies reduce flight costs, whereas larger bodies are advantageous for diving deeper. This study examines individual wintering strategies of deep diving thick-billed murres (Uria lomvia) breeding at three colonies in the south-eastern Bering Sea: St Paul, St George and Bogoslof. These colonies, arranged north to south, are located such that breeding birds forage …

Enos Transfection Of Adipose-Derived Stem Cells Yields Bioactive Nitric Oxide Production And Improved Results In Vascular Tissue Engineering., Stephen Mcilhenny, Ping Zhang, Thomas Tulenko, Jason Comeau, Sarah Fernandez, Aleksandra Policha, Matthew Ferroni, Elizabeth J Faul, Gabor Bagameri, Irving Shapiro, Paul J. Dimuzio

Department of Surgery Faculty Papers

This study evaluates the durability of a novel tissue engineered blood vessel (TEBV) created by seeding a natural vascular tissue scaffold (decellularized human saphenous vein allograft) with autologous adipose-derived stem cells (ASC) differentiated into endothelial-like cells. Previous work with this model revealed the graft to be thrombogenic, likely due to inadequate endothelial differentiation as evidenced by minimal production of nitric oxide (NO). To evaluate the importance of NO expression by the seeded cells, we created TEBV using autologous ASC transfected with the endothelial nitric oxide synthase (eNOS) gene to produce NO. We found that transfected ASC produced NO at levels …

How Kinetic Property Shapes Novelty Perceptions, Junghan Kim, Arun Lakshmanan

Research Collection Lee Kong Chian School Of Business

This article demonstrates a new substantive finding: that kinetic property in advertising, defined as direction changes in the paths of moving on-screen ad elements, enhances consumer judgments of product novelty. Across six studies, the authors first outline an inference-based theory as to why the novelty-enhancing effect of kinetic property manifests: kinetic property generates impressions of how visually lively an ad is, which leads to inferences of product atypicality and, consequently, higher novelty judgments. Second, they demonstrate boundary conditions by showing that (1) the positive effect for kinetic property is evident with incremental (and not radical) innovations, (2) the effect dissipates …

A Positive-Negative Mode Of Population Covariation Links Brain Connectivity, Demographics And Behavior, Stephen M. Smith, Thomas E. Nichols, Diego Vidaurre, Anderson M. Winkler, Timothy E J Behrens, Matthew F. Glasser, Kamil Ugurbil, Deanna M. Barch, David C. Van Essen, Karla L. Miller

School of Medicine Publications

We investigated the relationship between individual subjects' functional connectomes and 280 behavioral and demographic measures in a single holistic multivariate analysis relating imaging to non-imaging data from 461 subjects in the Human Connectome Project. We identified one strong mode of population co-variation: subjects were predominantly spread along a single 'positive-negative' axis linking lifestyle, demographic and psychometric measures to each other and to a specific pattern of brain connectivity.

Dreissenid Mussel Research Priorities Workshop, Mark D. Sytsma, Stephen Phillips, Timothy D. Counihan

Center for Lakes and Reservoirs Publications and Presentations

Currently, dreissenid mussels have yet to be detected in the northwestern part of the United States and western Canada. Infestation of one of the jurisdictions within the mussel-free Pacific Northwest would likely have significant economic, soci­etal and environmental implications for the entire region. Understanding the biology and environmental tolerances of dreissenid mussels, and effectiveness of various man­agement strategies, is key to prevention.

On November 4-5, 2015, the Aquatic Bioinvasion Research and Policy Institute and the Center for Lakes and Reservoirs at Portland State University, the US Geological Survey, and the Pacific States Marine Fisheries Commission, convened a Dreissenid Mussel Research …

Handedness For Unimanual Grasping In 564 Great Apes: The Effect On Grip Morphology And A Comparison With Hand Use For A Bimanual Coordinated Task, A. Meguerditchian, Kimberley A. Phillips, A. Chapelain, L. M. Mahovetz, S. Milne, T. Stoinski, A. Bania, E. V. Lonsdorf, J. Schaeffer, J. Russell, William D. Hopkins

Psychology Faculty Research

A number of factors have been proposed to influence within and between species variation in handedness in non-human primates. In the initial study, we assessed the influence of grip morphology on hand use for simple reaching in a sample of 564 great apes including 49 orangutans Pongo pygmaeus, 66 gorillas Gorilla gorilla, 354 chimpanzees Pan troglodytes and 95 bonobos Pan paniscus. Overall, we found a significant right hand bias for reaching. We also found a significant effect of the grip morphology of hand use. Grasping with the thumb and index finger was more prevalent in the right …

Time To Say Local Cheese And Smile At Geographical Indications Of Origin? International Trade And Local Development In The United States, Irene Calboli

Research Collection Yong Pung How School Of Law

In this Article, I offer some considerations on a possible compromising solution for the controversy between the European Union (EU) and the United States (U.S.) on the regulation of geographical indications of origin (GIs) as part of the negotiations in the Transatlantic Trade and Investment Partnership (TTIP). Notably, I advocate that the EU and the U.S. consider adopting a solution similar to that adopted in the Canada and European Union Comprehensive Economic and Trade Agreement (CETA). In particular, I note that, even though CETA accepted several of the EU’s requests to claw-back names that were not previously protected in Canada, …

All Works

© 2015 The Authors. Physiological Reports published by Wiley Periodicals, Inc. on behalf of the American Physiological Society and The Physiological Society. Cardiovascular complications are common in patients with Diabetes mellitus (DM). In addition to changes in cardiac muscle inotropy, electrical abnormalities are also commonly observed in these patients. We have previously shown that spontaneous cellular electrical activity is altered in atrioventricular nodal (AVN) myocytes, isolated from the streptozotocin (STZ) rat model of type-1 DM. In this study, utilizing the same model, we have characterized the changes in L-type calcium channel activity in single AVN myocytes. Ionic currents were recorded …

Repression Of Esophageal Neoplasia And Inflammatory Signaling By Anti-Mir-31 Delivery In Vivo., Cristian Taccioli, Michela Garofalo, Hongping Chen, Yubao Jiang, Guidantonio Malagoli Tagliazucchi, Gianpiero Di Leva, Hansjuerg Alder, Paolo Fadda, Justin Middleton, Karl J. Smalley, Tommaso Selmi, Srivatsava Naidu, John L. Farber, Carlo M. Croce, Louise Fong

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Overexpression of microRNA-31 (miR-31) is implicated in the pathogenesis of esophageal squamous cell carcinoma (ESCC), a deadly disease associated with dietary zinc deficiency. Using a rat model that recapitulates features of human ESCC, the mechanism whereby Zn regulates miR-31 expression to promote ESCC is examined.

METHODS: To inhibit in vivo esophageal miR-31 overexpression in Zn-deficient rats (n = 12-20 per group), locked nucleic acid-modified anti-miR-31 oligonucleotides were administered over five weeks. miR-31 expression was determined by northern blotting, quantitative polymerase chain reaction, and in situ hybridization. Physiological miR-31 targets were identified by microarray analysis and verified by luciferase reporter …

Capital As Artificial Intelligence, Gerry Canavan

English Faculty Research and Publications

This article examines science-fictional allegorizations of Soviet-style planned economies, financial markets, autonomous trading algorithms, and global capitalism writ large as nonhuman artificial intelligences, focussing primarily on American science fiction of the Cold War period. Key fictional texts discussed include Star Trek, Isaac Asimov's Machine stories, Terminator, Kurt Vonnegut's Player Piano (1952), Charles Stross's Accelerando (2005), and the short stories of Philip K. Dick. The final section of the article discusses Kim Stanley Robinson's novel 2312 (2012) within the contemporary political context of accelerationist anticapitalism, whose advocates propose working with “the machines” rather than against them.

Factors Associated With High Risk Infant Follow-Up Attendance, Martha Grant Fuller

Dissertations

Prematurity is a significant public health problem and preterm infants face well described risks of adverse neurodevelopmental outcomes. Bronfenbrenner’s bioecological theory of development describes interactions between biological and environmental factors and explains how these interactions can impact development. Systematic follow-up of preterm, high-risk infants is recommended for early identification of problems and provision of interventions and support services. Most research on follow-up attendance has involved small, single sites. A retrospective analysis of population based data available in the California Children’s Services High Risk Infant Follow-up Quality of Care Initiative (HRIF-QCI) data system was performed to examine factors associated with attendance …

Partial Covariance Based Functional Connectivity Computation Using Ledoit-Wolf Covariance Regularization, Matthew R. Brier, Anish Mitra, John E. Mccarthy, Beau M. Ances, Abraham Z. Snyder

Mathematics Faculty Research

Highlights •We use the well characterized matrix regularization technique described by Ledoit and Wolf to calculate high dimensional partial correlations in fMRI data. •Using this approach we demonstrate that partial correlations reveal RSN structure suggesting that RSNs are defined by widely and uniquely shared variance. •Partial correlation functional connectivity is sensitive to changes in brain state indicating that they contain functional information. Functional connectivity refers to shared signals among brain regions and is typically assessed in a task free state. Functional connectivity commonly is quantified between signal pairs using Pearson correlation. However, resting-state fMRI is a multivariate process exhibiting a …

Challenges In The Pharmacokinetics Of Therapeutic Proteins, Wararat Limothai

Theses and Dissertations (ETD)

Due to the complex structure and complicated disposition pattern of therapeutic macromolecules, their pharmacokinetic interpretation has many challenges. Two of these challenges were investigated in this dissertation: 1) the error of classical bioavailability assessment observed during subcutaneous (SC) administration of therapeutic macromolecules that undergo target-mediated drug disposition (TMDD) and 2) the ontogeny of the neonatal Fc receptor (FcRn) expression along with its effect on the pharmacokinetics of monoclonal antibodies (mAbs) during development.

TMDD often well describes the pharmacokinetics of therapeutic proteins that have high specificity and affinity of binding to their target receptors. The target receptors can be saturated by …

Computational Replication Of The Patient-Specific Stenting Procedure For Coronary Artery Bifurcations: From Oct And Ct Imaging To Structural And Hemodynamics Analyses, Claudio Chiastra, Wei Wu, Benjamin Dickerhoff, Ali Aleiou, Gabriele Dubini, Hiromasa Otake, Francesco Migliavacca, John F. Ladisa Jr.

Biomedical Engineering Faculty Research and Publications

The optimal stenting technique for coronary artery bifurcations is still debated. With additional advances computational simulations can soon be used to compare stent designs or strategies based on verified structural and hemodynamics results in order to identify the optimal solution for each individual’s anatomy. In this study, patient-specific simulations of stent deployment were performed for 2 cases to replicate the complete procedure conducted by interventional cardiologists. Subsequent computational fluid dynamics (CFD) analyses were conducted to quantify hemodynamic quantities linked to restenosis.

Patient-specific pre-operative models of coronary bifurcations were reconstructed from CT angiography and optical coherence tomography (OCT). Plaque location and …

Improved Cardiorespiratory Fitness Is Associated With Increased Cortical Thickness In Mild Cognitive Impairment, Katherine Reiter, Kristy A. Nielson, Theresa J. Smith, Lauren R. Weiss, Alfonso J. Alfini, J. C. Smith

Psychology Faculty Research and Publications

Cortical atrophy is a biomarker of Alzheimer’s disease (AD) that correlates with clinical symptoms. This study examined changes in cortical thickness from before to after an exercise intervention in mild cognitive impairment (MCI) and healthy elders. Thirty physically inactive older adults (14 MCI, 16 healthy controls) underwent MRI before and after participating in a 12-week moderate intensity walking intervention. Participants were between the ages of 61 and 88. Change in cardiorespiratory fitness was assessed using residualized scores of the peak rate of oxygen consumption (V̇O_2peak) from pre- to post-intervention. Structural magnetic resonance images were processed using FreeSurfer v5.1.0. …

The Evolution Of Digit Form In Gonatodes (Gekkota: Sphaerodactylidae) And Its Bearing On The Transition From Frictional To Adhesive Contact In Gekkotans, Anthony P. Russell, Joelle Baskerville, Tony Gamble, Timothy E. Higham

Biological Sciences Faculty Research and Publications

Although the phenomenon of adhesion in geckos has been intensively studied for over 200 years, our understanding of how the morphological apparatus associated with this arose is less clear. Indeed, whether or not all of the intricate morphological hierarchy that is implicated in the attachment and removal of the adhesive setae originated at the same time is unknown. To explore whether setae may have arisen prior to the other parts of this structural hierarchy, we undertook morphological observations of Gonatodes, an ancestrally padless, sphaerodatyline genus known to exhibit the expression of incipient subdigital pads in some species. Focusing on …

Occupational Exposure To Chemical And Physical Contaminants: Sex-Differentiated Analysis, France Labrèche, Aude Lacourt, Jérôme Lavoué

Rapports de recherche scientifique

La survenue des lésions professionnelles varie selon le sexe. Une des principales explications évoquées est l’existence de nettes différences d’exposition en milieu de travail, découlant notamment des professions occupées par les hommes et par les femmes et de la nature des tâches effectuées. Cependant, il n’existe pas de données solides pour appuyer cette assertion et les analyses traditionnelles en milieu de travail se sont le plus souvent limitées à rapporter le risque en fonction du sexe, sans identifier les raisons pouvant expliquer les différences de risque observées.
