Influence Of Edge Effects On Laser-Induced Surface Displacement Of Opaque Materials By Photothermal Interferometry, G. A. S. Flizikowski, B. Anghinoni, J. H. Rohling, M. P. Belançon, R. S. Mendes, M. L. Baesso, L. C. Malacarne, T. Požar, Stephen E. Bialkowski, N. G. C. Astrath

Chemistry and Biochemistry Faculty Publications

We demonstrate the influence of edge effects on the photothermal-induced phase shift measured by a homodyne quadrature laser interferometer and compare the experiments with rigorous theoretical descriptions of thermoelastic surface displacement of metals. The finite geometry of the samples is crucial in determining how the temperature is distributed across the material and how this affects the interferometer phase shift measurements. The optical path change due to the surface thermoelastic deformation and thermal lens in the surrounding air is decoded from the interferometric signal using analytical and numerical tools. The boundary/edge effects are found to be relevant to properly describe the …

What Is The Storage Effect, Why Should It Occur In Cancers, And How Can It Inform Cancer Therapy?, Anna K. Miller, Joel S. Brown, David Basanta, Nancy Huntly

Ecology Center Publications

Intratumor heterogeneity is a feature of cancer that is associated with progression, treatment resistance, and recurrence. However, the mechanisms that allow diverse cancer cell lineages to coexist remain poorly understood. The storage effect is a coexistence mechanism that has been proposed to explain the diversity of a variety of ecological communities, including coral reef fish, plankton, and desert annual plants. Three ingredients are required for there to be a storage effect: (1) temporal variability in the environment, (2) buffered population growth, and (3) species-specific environmental responses. In this article, we argue that these conditions are observed in cancers and that …

His And Hers: Gender-Specific Design In Mid-Twentieth Century North America Through Film And Television, Morgan O'Shaughnessy

Architecture Masters of Science Program: Theses

The built environment exists as a variety of ‘spaces’ which are constructed by, and for, the people who occupy them. What is the relationship between social constructs of gender and our built environment in the 20^th century? How does film and television representing the mid-20^th century exemplify this relationship? The overall theme of this topic will include a positive relationship between social gender constructs and our built environment. Through the exploration of select film and television, this study attempts to answer the question of how gender-focused design reinforces traditional gender roles in North American society in mid-20^{th …}

Predation Environment Does Not Predict Life History In Morphologically-Constrained Fish Alfaro Cultratus (Cyprinodontiformes: Poeciliidae), Kaitlyn Beard Golden

Theses and Dissertations

Predation is known to have a significant effect on life history, eliciting predictable responses. Physical constraints of body shape and size may also limit life history divergence. There may be a trade-off between adapting to predation, and limits placed by constraints that decrease life history divergence. We test this idea in the Costa Rican livebearing fish Alfaro cultratus. This species has a keeled ventral surface and does not develop a distended abdomen when pregnant like other livebearers. We describe the life history of A. cultratus in 20 different populations across predator and non-predator environments. We found significantly lower reproductive allotment …

Spatial And Temporal Patterns Of Bat Activity In A Southeast Nebraska Agricultural Landscape, Christopher Fill

School of Natural Resources: Dissertations, Theses, and Student Research

Intensive agriculture is associated with biodiversity loss and species decline. Yet wild species, such as bats, may provide critical ecosystem services to agriculture, even in transformed landscapes. In the United States, bats have been estimated to save the agricultural industry billions of dollars per year. However, white-nose syndrome and habitat loss have led to the decline of many bat species in North America, including the federally threatened northern long-eared bat, Myotis septentrionalis.

To better evaluate the effectiveness of these pest-controlling services, and to increase understanding of bat foraging behavior in these extreme landscapes, I deployed 11 grids of 24 detectors, …

Joint Lattice Of Reconstructability Analysis And Bayesian Network General Graphs, Marcus Harris, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper integrates the structures considered in Reconstructability Analysis (RA) and those considered in Bayesian Networks (BN) into a joint lattice of probabilistic graphical models. This integration and associated lattice visualizations are done in this paper for four variables, but the approach can easily be expanded to more variables. The work builds on the RA work of Klir (1985), Krippendorff (1986), and Zwick (2001), and the BN work of Pearl (1985, 1987, 1988, 2000), Verma (1990), Heckerman (1994), Chickering (1995), Andersson (1997), and others. The RA four variable lattice and the BN four variable lattice partially overlap: there are ten …

Synthesizing Expressive Behaviors For Humanoid Robots, Mathias Irwan Sunardi

Dissertations and Theses

Humanoid robots are expected to be able to communicate with expressive gestures at the same level of proficiency as humans. However, creating expressive gestures for humanoid robots is difficult and time consuming due to the high number of degrees of freedom (DOF) and the iterations needed to get the desired expressiveness.

Current robot motion editing software has varying levels of sophistication of motion editing tools ranging from basic ones that are text-only, to ones that provide graphical user interfaces (GUIs) which incorporate advanced features, such as curve editors and inverse kinematics. These tools enable users to create simple motions; but …

Gardner-Webb NewsCenter Archive

For the last 18 years, Dr. Tom Jones, Gardner-Webb University professor of biology, has given Honors Students the opportunity to join the annual cleanup event at New River in West Jefferson, N.C. The weekend event is aptly name “Mud, Sweat and Volunteers.” Participants sleep in tents and spend a day paddling down the river in canoes picking up trash as they go. Last year, 27 GWU students and eight guests made the trip and were among a group of over 100 volunteers who covered approximately 23 river miles.

Assessing Textbook Costs At A Small College, Stephen G. Krueger, Lewis Ward

Dartmouth Library Staff Publications

In recent years, the cost of textbooks has risen drastically, making it an important issue for everyone involved in higher education. Accurate and specific information on the cost of textbooks is needed to effectively address the situation. Over the summer of 2018, a librarian and an undergraduate student at a small liberal arts college assessed the textbook costs at their institution, using methodology developed by community colleges doing similar research. Based on course catalogs, bookstore records, and other resources, they calculated the costs for students in different disciplines over four years of study. These costs were impacted by major, courses …

© Copyright © 2020 Ahmed, Khan, Kury and Shah. Background: Carveol is a natural drug product present in the essential oils of orange peel, dill, and caraway seeds. The seed oil of Carum Carvi has been reported to be antioxidant, anti-inflammatory, anti-hyperlipidemic, antidiabetic, and hepatoprotective. Methods: The antidiabetic potential of carveol was investigated by employing in-vitro, in-vivo, and in-silico approaches. Moreover, alpha-amylase inhibitory assay and an alloxan-induced diabetes model were used for in-vitro and in-vivo analysis, respectively. Results: Carveol showed its maximum energy values (≥ -7 Kcal/mol) against sodium-glucose co-transporter, aldose reductase, and sucrose-isomaltase intestinal, whereas it exhibited intermediate energy …

Whole Exome Sequencing In Patients With Williams-Beuren Syndrome Followed By Disease Modeling In Mice Points To Four Novel Pathways That May Modify Stenosis Risk, Phoebe C R Parrish, Delong Liu, Russell H Knutsen, Charles J Billington, Robert P Mecham, Yi-Ping Fu, Beth A Kozel

2020-Current year OA Pubs

Supravalvular aortic stenosis (SVAS) is a narrowing of the aorta caused by elastin (ELN) haploinsufficiency. SVAS severity varies among patients with Williams-Beuren syndrome (WBS), a rare disorder that removes one copy of ELN and 25-27 other genes. Twenty percent of children with WBS require one or more invasive and often risky procedures to correct the defect while 30% have no appreciable stenosis, despite sharing the same basic genetic lesion. There is no known medical therapy. Consequently, identifying genes that modify SVAS offers the potential for novel modifier-based therapeutics. To improve statistical power in our rare-disease cohort (N = 104 exomes), …

Machine Learning Approaches For Fracture Risk Assessment: A Comparative Analysis Of Genomic And Phenotypic Data In 5130 Older Men, Qing Wu, Fatma Nasoz, Jongyun Jung, Bibek Bhattarai, Mira V. Han

Virus Infection Is Controlled By Hematopoietic And Stromal Cell Sensing Of Murine Cytomegalovirus Through Sting, Sytse J. Piersma, Jennifer Poursine-Laurent, Liping Yang, Glen N. Barber, Bijal A. Parikh, Wayne M. Yokoyama

Open Access Publications

Recognition of DNA viruses, such as cytomegaloviruses (CMVs), through pattern-recognition receptor (PRR) pathways involving MyD88 or STING constitute a first-line defense against infections mainly through production of type I interferon (IFN-I). However, the role of these pathways in different tissues is incompletely understood, an issue particularly relevant to the CMVs which have broad tissue tropisms. Herein, we contrasted anti-viral effects of MyD88 versus STING in distinct cell types that are infected with murine CMV (MCMV). Bone marrow chimeras revealed STING-mediated MCMV control in hematological cells, similar to MyD88. However, unlike MyD88, STING also contributed to viral control in non-hematological, stromal …

Environmental Surveillance As A Tool For Identifying High-Risk Settings For Typhoid Transmission, Jason R. Andrews, Alexander T. Yu, Senjuti Saha, Jivan Shakya, Kristen Aiemjoy, Lily Horng, Farah Qamar, Denise Garret, Stephen Baker, Samir Saha, Stephen P. Luby

Department of Paediatrics and Child Health

Enteric fever remains a major cause of morbidity in developing countries with poor sanitation conditions that enable fecal contamination of water distribution systems. Historical evidence has shown that contamination of water systems used for household consumption or agriculture are key transmission routes for Salmonella Typhi and Salmonella Paratyphi A. The World Health Organization now recommends that typhoid conjugate vaccines (TCV) be used in settings with high typhoid incidence; consequently, governments face a challenge regarding how to prioritize typhoid against other emerging diseases. A key issue is the lack of typhoid burden data in many low- and middle-income countries where TCV …

Energy Stores And Life-History Transitions In Red-Sided Garter Snakes (Thamnophis Sirtalis Parietalis), Rachel Catharine Wilson

Dissertations and Theses

All organisms must prioritize investment in either reproductive or self-maintenance activities. Despite this established paradigm, our understanding of how organisms choose to prioritize certain behaviors and physiologies over others remains limited. It is likely that an organism's energy status not only influences variation in reproductive effort, but also transitions to and from reproductive activities. My dissertation aims to investigate how energy metrics (body condition index, adipocyte follicle size, and liver glycogen) relate to reproduction and associated life-history stages in red-sided garter snakes (Thamnophis sirtalis parietalis). Chapter two examines if energy metrics differ with migratory status and sex in …
