Tunable Topological Photonic Crystal Waveguides, Menglin L.N. Chen, Li (Lijun) Jun Jiang, Wei E.I. Sha

Electrical and Computer Engineering Faculty Research & Creative Works

Edge states in topological photonic systems have the robust unidirectional propagation feature which originates from the topological nature of the bulk band dispersion. In this work, we propose a topological photonic crystal (PC) waveguide that is formed by introducing an air gap in an all-dielectric PC with C-{6v} symmetry. The dispersion of the line defect states is tunable by varying the width of the air gap. Based on their field distributions, the states can be classified into even- and odd-symmetric states. The even-symmetric states are found to be the nontrivial topological edge states and exhibit pseudospin-locking unidirectional propagation property. By …

Design Validation Of A Multi-Stage Gradually Deploying Stent, Dillon J. Despain

Theses and Dissertations

Angioplasty, or the use of rapidly deploying stents, is a common treatment for reopening narrowed vasculature often caused by atherosclerotic plaque. However, in-stent restenosis (ISR) induced by intimal hyperplasia is a common challenge to angioplasty. High impact stresses from current stent deployment processes have been linked to intimal hyperplasia; thus a stent that is gradually deployed over a longer period of time holds potential to mitigate these stresses. This work hypothesizes that resorbable polymeric links can be used as a triggering mechanism to enable repeatably controlled deployment of a compliant nitinol stent design with the eventual goal of reducing intimal …

Cultivating Graduate Stem Pathways: How Alliance-Based Stem Enrichment Programs Broker Opportunity For Students Of Color, Ariana L. Garcia, Tonisha B. Lane, Blanca E. Rincón

Educational Psychology, Leadership, and Higher Education Faculty Research

To understand how higher education institutions broker graduate opportunities for Students of Color (SOCs) in STEM, we employ a single case study of a Louis Stokes Alliance for Minority Participation (LSAMP) alliance. Drawing primarily from student interviews and informed by Small’s (2006) organizational brokerage theory, our findings illuminate how 1) alliance-based STEM enrichment programs (SEPs) bridge social capital via interorganizational networks and 2) how SEP instability creates barriers to building the trust that is central to the brokerage process. We conclude with recommendations for future research and practice.

Centre of Excellence in Women and Child Health

Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa. In order to classify IUs that include locations that are environmentally suitable, we used receiver operating characteristic (ROC) analysis to identify an optimal threshold for suitability concordant with locations where …

Otieno, Tullu Bukhari, Thomas O. Onchuru, Evan Teal, Juan Paredes, Joel L. Bargul, David M. Mburu, Everline A. Onyango, Gabriel Magoma, Steven P. Sinkins, Jeremy K. Herren

All Peer-Reviewed Publications

The recently discovered Anopheles symbiont, Microsporidia MB, has a strong malaria transmission-blocking phenotype in Anopheles arabiensis, the predominant Anopheles gambiae species complex member in many active transmission areas in eastern Africa. The ability of Microsporidia MB to block Plasmodium transmission together with vertical transmission and avirulence makes it a candidate for the development of a symbiont-based malaria transmission blocking strategy. We investigate the characteristics and efficiencies of Microsporidia MB transmission between An. arabiensis mosquitoes. We show that Microsporidia MB is not transmitted between larvae but is effectively transmitted horizontally between adult mosquitoes. Notably, Microsporidia MB was only found to be …

Pt-Containing Conjugated Polymers And Small Molecules For Bhj Photovoltaic Devices, Yunjeong Kwon

Chemistry and Chemical Biology ETDs

The current state of organic photovoltaic (OPV) devices involve series of small molecular or polymeric systems that can absorb light from the solar spectrum in concert with another material that acts as an acceptor material. Together these materials serve to generate and split bound excitation species then transport the separate charges to their respected electrode. Several limitations have restricted the widescale use of these materials. Since these devices have their genesis in organic materials the OPV devices inherit short exitonic lifetimes, narrow absorption window and a lack of precise control over the morphology. To overcome these limitations, additional molecular engineering …

Optimizing University Campuses For Learning, Wellbeing And Equity: An Applied Study Of Higher Education Facilities Organizational Systems, Melissa Nergard

Theses and Dissertations

College and university campuses are designed and maintained by experts in facilities management and planning. What is lacking in these processes is expertise in learning environments and creating spaces that are healthy and inclusive. University organizational structures aid in the autonomy of academic freedom and the nimbleness of research endeavors but hinder operational effectiveness of the campus as a learning and research environment. A more integrated approach, which optimizes the knowledge on campus regardless of where it is housed, can mitigate the unintended conflicts that develop through the disparate approach to learning, equity, and wellbeing in the built environment. This …

Mediation Among Depression, Acceptability Of Emotions, Emotional Intensity And Emotional Disclosure, Brandie Vera

Theses and Dissertations

The present study discussed talking about emotions with other people and the important role in emotional recovery (Rimé, 2009). Individuals with depression, however, have been shown to disclose less personal information than individuals without depression (Kahn & Garrison, 2009). Little is known about the roles of acceptance of emotions and emotional intensity in the association between depression symptoms and emotional disclosure. The degree to which one believes their emotions are acceptable and the perceived intensity of emotional events might be mediators of the depression-disclosure relation. The hypotheses of the study include: Depressive symptoms will be negatively associated with emotional disclosure. …

2020-Current year OA Pubs

BACKGROUND: Copy number variants (CNVs) linked to genes involved in nervous system development or function are often associated with neuropsychiatric disease. While CNVs involving deletions generally cause severe and highly penetrant patient phenotypes, CNVs leading to duplications tend instead to exhibit widely variable and less penetrant phenotypic expressivity among affected individuals. CNVs located on chromosome 15q13.3 affecting the alpha-7 nicotinic acetylcholine receptor subunit (CHRNA7) gene contribute to multiple neuropsychiatric disorders with highly variable penetrance. However, the basis of such differential penetrance remains uncharacterized. Here, we generated induced pluripotent stem cell (iPSC) models from first-degree relatives with a 15q13.3 duplication and …

Fisheries Research Articles

Marine fisheries in coastal ecosystems in many areas of the world have historically removed large-bodied individuals, potentially impairing ecosystem functioning and the long-term sustainability of fish populations. Reporting on size-based indicators that link to food-web structure can contribute to ecosystem-based management, but the application of these indicators over large (cross-ecosystem) geographical scales has been limited to either fisheries-dependent catch data or diver-based methods restricted to shallow waters (<20 m) that can misrepresent the abundance of large-bodied fished species. We obtained data on the body-size structure of 82 recreationally or commercially targeted marine demersal teleosts from 2904 deployments of baited remote underwater stereo-video (stereo-BRUV). Sampling was at up to 50 m depth and covered approximately 10,000 km of the continental shelf of Australia. Seascape relief, water depth, and human gravity (i.e., a proxy of human impacts) were the strongest predictors of the probability of occurrence of large fishes and the abundance of fishes above the minimum legal size of capture. No-take marine reserves had a positive effect on the abundance of fishes above legal size, although the effect varied across species groups. In contrast, sublegal fishes were best predicted by gradients in sea surface temperature (mean and variance). In areas of low human impact, large fishes were about three times more likely to be encountered and fishes of legal size were approximately five times more abundant. For conspicuous species groups with contrasting habitat, environmental, and biogeographic affinities, abundance of legal-size fishes typically declined as human impact increased. Our large-scale quantitative analyses highlight the combined importance of seascape complexity, regions with low human footprint, and no-take marine reserves in protecting large-bodied fishes across a broad range of species and ecosystem configurations.
