Evaluation Of Stretch Film Behavior During Long-Term Storage Under Different Atmospheric Conditions, Kyle Dunno, Maria Symanski

Journal of Applied Packaging Research

This study examined the post-application behavior of two 20.3 micron machine stretch films, one categorized as high-performance and one as general-performance, for thirty days while stored at either 23°C or 38°C. For each film type, the stretch film was applied to a simulated unit load to produce neutral and positive applied total stretch scenarios. The relaxation curves developed from each test indicate the relaxation rate of the films varied based on the storage condition. Observed was an average of 41% containment loss for both high-performance and general-purpose films when the simulated loads were stored at 38°C. For simulated loads stored …

Examining Own-Race Bias: A Cooperation And Memory Study Using Diverse Emojis, Jillian Franks

Theses

Other-race-effect or own-race bias is a well-documented phenomenon in memory. Findings suggest that humans are better at recognizing and remembering faces of their own race than other races. Previous research suggests that these results are due to a lack of interracial contact or exposure to other racial groups. Evidence from previous studies has demonstrated that individuals process own-race faces differently than other-race faces, paying more attention to more salient features that become better encoded. While there is empirical support for both hypotheses, it has yet to be studied if the other-race effect for memory extends to representational human faces, for …

Adapting To Sea Level Rise: Insights From A New Evaluation Framework Of Physical Design Projects, Daniella Hirschfeld, Kristina E. Hill, Ellen Plane

Landscape Architecture and Environmental Planning Faculty Publications

Designers and engineers are developing proposals for physical projects to adapt coastal sites to future sea level rise related threats. This puts pressure on local and regional decision makers to develop strategic frameworks for prioritizing, permitting and funding such projects. However, no systematic evaluation tools exist for the full range of these innovative designs. We build on the literature to develop an evaluation framework that synthesizes two different approaches to categorize these proposals and provide insight for coastal managers and decision makers. We apply this framework to physical projects that address sea level rise in their design around the San …

Reducing The Manual Annotation Effort For Handwriting Recognition Using Active Transfer Learning, Eric Burdett

Theses and Dissertations

Handwriting recognition systems have achieved remarkable performance over the past several years with the advent of deep neural networks. For high-quality recognition, these models require large amounts of labeled training data, which can be difficult to obtain. Various methods to reduce this effort have been proposed in the realms of active and transfer learning, but not in combination. We propose a framework for fitting new handwriting recognition models that joins active and transfer learning into a unified framework. Empirical results show the superiority of our method compared to traditional active learning, transfer learning, or standard supervised training schemes.

Cd7-Deleted Hematopoietic Stem Cells Can Restore Immunity After Car T Cell Therapy, Miriam Y. Kim, Matthew L. Cooper, Miriam T. Jacobs, Julie K. Ritchey, Julia Hollaway, Todd A. Fehniger, John F. Dipersio

Open Access Publications

Targeting T cell malignancies with universal CD7-targeting chimeric antigen receptor T cells (UCART7) can lead to profound immune deficiency due to loss of normal T and NK cells. While a small population of endogenous CD7- T cells exists, these cells are unlikely to be able to repopulate the entire immune repertoire after UCART7 treatment, as they are limited in number and proliferative capacity. To rescue T and NK cells after UCART7, we created hematopoietic stem cells genetically deleted for CD7 (CD7-KO HSCs). CD7-KO HSCs were able to engraft immunodeficient mice and differentiate into T and NK cells lacking CD7 expression. …

Hpv Transcript Expression Affects Cervical Cancer Response To Chemoradiation, Fiona J Ruiz, Matthew Inkman, Ramachandran Rashmi, Naoshad Muhammad, Nishanth Gabriel, Christopher A Miller, Michael D Mclellan, Michael Goldstein, Stephanie Markovina, Perry W Grigsby, Jin Zhang, Julie K Schwarz

Open Access Publications

Persistent HPV infection is causative for the majority of cervical cancer cases; however, current guidelines do not require HPV testing for newly diagnosed cervical cancer. Using an institutional cohort of 88 patients with cervical cancer treated uniformly with standard-of-care chemoradiation treatment (CRT) with prospectively collected clinical outcome data, we observed that patients with cervical tumors containing HPV genotypes other than HPV 16 have worse survival outcomes after CRT compared with patients with HPV 16+ tumors, consistent with previously published studies. Using RNA sequencing analysis, we quantified viral transcription efficiency and found higher levels of E6 and the alternative transcript E6*I …

Open Access Publications

Evidence suggests an association between severe acute respiratory syndrome-cornavirus-2 (SARS-CoV-2) infection and the occurrence of new-onset diabetes. We examined pancreatic expression of angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2), the cell entry factors for SARS-CoV-2, using publicly available single-cell RNA sequencing data sets, and pancreatic tissue from control male and female nonhuman primates (NHPs) and humans. We also examined SARS-CoV-2 immunolocalization in pancreatic cells of SARS-CoV-2-infected NHPs and patients who had died from coronavirus disease 2019 (COVID-19). We report expression of ACE2 in pancreatic islet, ductal, and endothelial cells in NHPs and humans. In pancreata from SARS-CoV-2-infected …

Gum Arabic-Capped Silver Nanoparticles For Electrochemical Amplification Sensing Of Methylene Blue In River Water, Ziad Khalifa, Moustafa Zahran, Magdy Zahran, Magdi Abdelazzem

Chemical Engineering

Herein, a novel electrochemical amplification sensor is developed for detecting methylene blue (MB) us- ing gum Arabic-capped silver nanoparticles (AgNPs) for the first time. Gum Arabic-AgNPs were fabricated via a direct chemical reduction technique using silver nitrate as an AgNPs precursor and gum Arabic as a reducing and capping agent. They were characterized using ultraviolet-visible (UV–Vis) spectrophotom- etry, square wave voltammetry (SWV), and transmission electron microscopy (TEM). UV–Vis and SWV results show the characteristic absorption and electrochemical oxidation peaks of the AgNPs at 431 nm and 0.18 V, respectively. Additionally, TEM images of the AgNPs show that they are spherical …

Rewilding Of Protected Areas Enhances Resilience Of Marine Ecosystems To Extreme Climatic Events, E. V. Sheehan, L. A. Holmes, B. F.R. Davies, A. Cartwright, A. Rees, M. J. Attrill

School of Biological and Marine Sciences

Marine protected areas (MPAs) are employed as tools to manage human impacts, especially fishing pressure. By excluding the most destructive activities MPAs can rewild degraded areas of seabed habitat. The potential for MPAs to increase ecosystem resilience from storms is, however, not understood, nor how such events impact seabed habitats. Extreme storm disturbance impact was studied in Lyme Bay MPA, Southwest United Kingdom, where the 2008 exclusion of bottom-towed fishing from the whole site allowed recovery of degraded temperate reef assemblages to a more complex community. Severe storm impacts in 2013–2014 resulted in major damage to the seabed so that …

Cross-Frequency Coupling Explains The Preference For Simple Ratios In Rhythmic Behaviour And The Relative Stability Across Non-Synchronous Patterns, Dobromir Dotov, Laurel Trainor

Journal Articles

Rhythms are important for understanding coordinated behaviours in ecological systems. The repetitive nature of rhythms affords prediction, planning of movements and coordination of processes within and between individuals. A major challenge is to understand complex forms of coordination when they differ from complete synchronization. By expressing phase as ratio of a cycle, we adapted levels of the Farey tree as a metric of complexity mapped to the range between in-phase and anti-phase synchronization. In a bimanual tapping task, this revealed an increase of variability with ratio complexity, a range of hidden and unstable yet measurable modes, and a rank-frequency scaling …

The Effect Of Severe Intraventricular Hemorrhage On The Biorhythms Of Feeding In Premature Infants, Ira H. Gewolb, Babatunde T. Sobowale, Frank L. Vice, Abhijit R. Patwardhan, Nino Solomonia, Eric W. Reynolds

Biomedical Engineering Faculty Publications

Background: Suck-swallow rhythmicity and the integration of breathing into infant feeding are developmentally regulated. Neurological injury and breathing abnormalities can both impact feeding in preterm infants.

Objective: To determine the effects of neurologic injury independent of effects of disordered breathing on feeding biorhythms in premature infants.

Methods: Low-risk preterm infants (LRP), infants with Grade 3–4 Intraventricular Hemorrhage (IVH), those with bronchopulmonary dysplasia (BPD), and those with both BPD and IVH (BPD+IVH) were identified. Forty-seven infants, 32–42 weeks Postmenstrual Age (PMA) were evaluated on one or more occasions (131 studies). Of these, 39 infants (81 studies) were performed at >35 weeks …

Design Of An Inexpensive Pvc Shock Tube For Educational Use, Brandon Edward Bergmann

Theses and Dissertations

Herein is described the design and function of a low-cost, easy-to-assemble, -operate, and -disassemble shock tube platform experiment that can generate shock waves approaching Mach 2 at maximum pressures of ~100 psig with a helium driver gas. The experiment uses several inexpensive (<$5), unamplified piezoelectric sensors attached to a multichannel oscilloscope to monitor the passage of key features of the flow (i.e., incident shock and reflected shock) through the tube, constructed from inexpensive and easy to work with schedule 40 PVC pipe and fittings. From the fixed sensor displacements along the tube and relative differences in respective transit times, the velocities of these flow features can be determined. This permits (1) comparison of experimental results to the theoretical predictions of 1-D transient gas dynamics and (2) a leaping off point for discussion and quantification of non-idealities in the flow, including the shock wave development length, shock attenuation and boundary layer growth, and interactions of the reflected shock and contact surface. Experimental accessories (future work) for study of shock focusing and steady 2-D high speed flows are also briefly discussed. Assuming both pressurized, conditioned air at ~80-100 psig and a modern multi-channel oscilloscope are available at most institutions, the total cost to construct this experiment is around $500.
