Arundinella Stenostachya (Arundinella, Poaceae), A Reevaluated New Species From Se Asia, Liqiong Jiang, Zhenwen Liu, Ende Liu, Atchara Teerawatananon, Yuehua Wang, Hua Peng

Turkish Journal of Botany

Arundinella stenostachya, a new species, is described and illustrated. It is morphologically similar to A. decempedalis and A. bengalensis, but differs from the former species by the length of panicle branches, type of trichome on nodes and pedicels length, and from the latter in height and diameter of culms, the length and width of leaf blades, pedicels length, and the length of panicles and branches. The new species has been mistakenly identified as A. decempedalis and A. bengalensis. Molecular analyses based on ITS sequences also support A. stenostachya as a distinct species.

Velocity Field Measurements Of The California Sea Lion Propulsive Stroke Using Bubble Piv, Gino Perrotta, Frank E. Fish, Danielle S. Adams, Ariel M. Leahy, Abigal M. Downs, Megan C. Leftwich

Biology Faculty Publications

California sea lions are among the most agile of swimming mammals. Most marine mammals swim with their hind appendages-flippers or flukes, depending on the species-whereas sea lions use their foreflippers for propulsion and maneuvering. The sea lion's propulsive stroke generates thrust by forming a jet between the flippers and the body and by dragging a starting vortex along the suction side of the flipper. Prior experiments using robotic flippers have shown these mechanisms to be possible, but no flow measurements around live sea lions previously existed with which to compare. In this study, the flow structures around swimming sea lions …

Limited Court Access V. Poor And Indigent, Chinyere Anunobi

Honors Undergraduate Theses

In criminal cases, poor individuals must qualify as legally indigent to receive legal representation. In civil cases, poor and indigent individuals must find their own resources to support themselves since the government does not guarantee counsel. Without counsel, poor and indigent individuals are forced to find legal representation for these cases on their own, which can be difficult considering the expenses of fees and fines. Cognitive processes, including bias and stereotypes, create a barrier in advocacy because they cloud judgement of decision-makers, which can diminish the voice of this vulnerable community. Barriers like these create an invisible wall where limited …

Methods For Characterization Of Cl-001 Derived Exosomes As A Stimulating Agent For Nk Cells For Immunotherapy, Ilana Gomez Diaz

Honors Undergraduate Theses

The immune system is a complex set of cells in the body that work to prevent disease or infection by recognizing and eliminating foreign material or unhealthy cells. One essential type of immune cell that is part of the innate immune response are Natural Killer (NK) cells. These cytotoxic effector lymphocytes can detect certain unhealthy cells, such as cancer cells, that normal B and T cells would miss. For example, many tumor cells have evolved to bypass immune system surveillance by not expressing major histocompatibility complex class I molecules (MHC class I), on their surface, reducing recognition by cytotoxic T …

The Effect Of Young Blood Anti-Aging Treatment On Protein Markers Of Age And Huntington Disease, Sujena H. Koilpillai

Honors Undergraduate Theses

Huntington disease (HD) is a neurodegenerative disorder caused by expansion of a polyglutamine tract within the huntingtin (HTT) protein, forming mutant HTT (mtHTT). HD patients suffer from psychiatric, behavioral, cognitive, and motor abnormalities, with death typically occurring 15-20 years after symptom onset. Currently, there are no treatments able to slow disease progression or delay onset. HD is a disease of aging. Despite the mtHTT protein being produced throughout life, symptoms do not typically appear until adulthood. Furthermore, many cellular effects of normal aging are also seen in HD, including altered intercellular communication and loss of proteostasis. Recently, our lab found …

Regulation Of The Protease Activity For The Mitochondrial Omi/Htra2, Simon Larson

Honors Undergraduate Theses

Human High Temperature requirement A2 (HtrA2) also known as Omi, is a serine protease located in the mitochondria with an important function in both cell survival and death. My results show the proteolytic activity of Omi/HtrA2 varies under different conditions. I characterized the optimal condition for Omi/HtrA2 protease activity using an in vitro assay system. Additionally, I identified a new allosteric regulation of Omi/HtrA2 through interaction with a specific substrate, the MUL1 protein. MUL1 is a multifunctional E3 ubiquitin ligase anchored in the outer mitochondrial membrane with domains both inside mitochondria and in the cytoplasm. The data shown here strongly …

The Role Of The Prefrontal Cortex And Stress In Huntington Disease-Mediated Aggression, Kadambari Vyas

Honors Undergraduate Theses

Huntington Disease (HD) is a fatal neurodegenerative disorder that is characterized by motor, cognitive, and psychiatric symptoms. Although HD onset is determined by motor symptoms, psychiatric symptoms, like depression and aggression, can develop earlier, have a larger impact on quality of life, and are understudied due to stigma. Our lab has observed hyper aggression in our humanized HD mouse model (Hu97/18) compared to our knock-in HD mouse model (Q175FDN). We characterized these differences and found that the Hu97/18 mice overreact in neutral situations, behaving as if they are in threatening situations. We are now using this novel model of HD-related …

The Relationship Between Sarcopenia And Diabetes Among Different Ethnic Groups, Rachel K. Williams

Honors Undergraduate Theses

Sarcopenia and diabetes are two conditions that reflect ongoing changes in global health trends: aging and obesity. Sarcopenia affects approximately 10-40% of the global population and type II diabetes affects around 415 million individuals (6.28% globally), with obesity contributing to a majority of the cases. Currently, approximately 9.3% of the population (727 million individuals) is aged 65 years or older; this number is predicted to reach 16% of the global population (around 1.5 billion individuals) in 2050. Many developed countries are undergoing demographic population pyramid rearrangements whereby an increasingly aging population must be supported by a shrinking youth cohort. Sarcopenia …

Chiang Mai’S Intangible Cultural Heritage : Urban Revitalization And Cultural Identity In A Northern Thai City, Alexandra Denes, Ajirapa Pradit

Journal of Urban Culture Research

Founded in 1296 CE, the walled city of Chiang Mai, Thailand was once the capital of the Lanna kingdom. In the sixteenth century, Chiang Mai’s fortunes waned, and it became a tributary state under the Burmese. This was followed by its incorporation into the Thai nation-state in the twentieth century. One outcome of Chiang Mai’s administrative integration into the Thai nation was the erosion of its distinctive cultural identity. Beginning in the 1980s, key local figures began to collaborate with communities and academic institutions to revitalize Chiang Mai’s intangible cultural heritage, including its craft traditions, rituals, textiles, and dance performances. …

The existence of zoos in cities provokes different reactions in people. Some view it to be an entertaining place to visit on an off day. Now, more often that people are not in favor of zoos anymore, for even though the idea of seeing wildlife in person is attractive, it is also sad to see these animals encaged and even more so under less optimal conditions. The purpose with this article is to investigate the impact of music and other human sounds in animals subject to captivity in the zoo, and if and how it creates changes in their behavior. …

Compact Lens Technologies: Curved Image Sensor And Volumetric Imaging Efficiency, Zhao Ma

Electronic Theses and Dissertations, 2020-2023

Compact image systems bring up people's attention in the field of target recognition, surveillance, situation awareness or even photography. Conventional metrics assess image system based on image quality without considering systems' volume. More comprehensive metrics, such as General Image-Quality Equation and the Targeting Task Performance metric, incorporates all image system components from object, lenses to detector and even imaging processing algorithm. All these key factors prohibit these metrics from being applied to image system in a convenient manner. Here, we propose a simple metric, volumetric imaging efficiency, considering both image quality and volume. Only concentrate on optical lenses enables the …

Generative Adversarial Networks For Extrapolation Of Corrosion In Automobile Images, Andre Von Zuben

Electronic Theses and Dissertations, 2020-2023

Deep learning has shown success in several applications involving pattern recognition, expert systems, and scientific discovery. However, existing methods struggle with industrial applications, which are often challenged by non-ideal datasets. In many cases, the datasets are small, poorly labeled, noisy, or have unbalanced class distribution or any combination of such problems. In this Master's research, we propose a generative adversarial network (GAN) strategy that is able to circumvent limitations imposed by tiny datasets. As a case study, we use the extrapolation of corrosion in automobiles and feed our deep learning framework with only a few dozen images instead of the …

The Fluid Dynamics Of A Spanwise-Morphing Wing: An Experimental And Analytical Study, Kamlesh Joshi

Electronic Theses and Dissertations, 2020-2023

The unsteady forces and fluid flow structure of a morphing wing are investigated for low Reynolds number (Re) flows, i.e., Re < 20,000. The morphing wing is designed to change shape in the spanwise direction in a controlled manner using internal actuation. The two types of wing morphing are studied in this work, i.e., spanwise bending and spanwise twisting. The wing morphing is named based on the overall shape of the wing after it is dynamically morphed.

Investigating Covariate Selection Criteria: To Draw Causal Inferences From Observational Data In The Presence Of Unmeasured Covariates Using Regression And Propensity Score Methods, Uday Nair

Electronic Theses and Dissertations, 2020-2023

The aim of causal effect estimation is to find the true impact of a treatment or exposure. Observational data is employed in social sciences to estimate causal effect but is susceptible to self-selection and unobserved confounding biases. Covariates included in analysis should strive to address these biases. This research focuses on investigating covariate selection approaches––common cause criterion (CC), Disjunctive Cause Criterion (DCC), Modified Disjunctive Cause Criterion (MDCC), and modified cause criterion (MCC)––in linear regression (LR) and propensity score methods (PSM) causal effect estimation in the presence of unmeasured confounding. Realistic social science scenarios such as––inclusion of proxy variables with varying …
