Description
The purpose of this study is to discover the exposure and network patterns during the 2013-2015 Ebola Virus Disease epidemic. The author accomplished this by taking an opportunistic sample of news and academic articles, some of which may also capture cases untreated and therefore unrecorded by hospitals and treatment units. Most of the 315 cases came from the Washington Post, New York Times, and World Health Organization, and they consistently captured between 1-2% of WHO case numbers. The results show that of cases with known exposures, 53.6% became infected through contact with sick family members. Hospital and funeral transmission accounted for the second and third most frequent exposure scenarios at 24.6% and 12.9% respectively. The exposures over time imply that hospital and funeral transmission prevention efforts have been successful, but family transmission has remained common throughout the outbreak. Prevention initiatives should focus on families earlier in epidemics to help control EVD's spread.

Description
The Tale of the Tigers is a children’s picture book in which a tiger named Guava is transported from his world of Serenia to our world. In an attempt to find someone to help him with this situation, Guava meets another tiger named Papaya. After having his prey scared away by Guava, Papaya begins to explain the different hardships and dangers that tigers face in their natural habitat. Papaya also teaches Guava about the different programs and activities that humans have been doing to help increase and restore tiger populations. At the end of the story, Guava returns to his world and spreads awareness to those that live in Serenia about how tigers are threatened in other places and what’s being done to help them. Papaya uses basic ecological concepts to explain the importance of tigers in their ecosystem. These concepts include habitat loss, trophic levels, landscape fragmentation, and poaching. The story also incorporates different conservation methods, including captive breeding and the use of camera traps.

Description
Food provides nutrients and sustenance that are essential to life. Humans rely on food to fuel our thoughts and actions. However, food isn’t just a source of energy; it’s a fundamental part of culture and connection. Simply sharing a meal with someone can build teamwork and create a bond. Throughout this short memoir, I explored the ways in which food creates a connection across language and cultural barriers through reflection on specific experiences that I had in India, Uganda, and South Africa. While my experiences in each of these three countries were vastly different, there was one defining theme that brought them together: food. This memoir uses mixed media (personal reflection, research, recipes, and photos) to connect the three different international experiences. Reflection on my own family traditions and history bridges the gap between my upbringing and my interactions with people while spending time abroad. Popular recipes from each of the three countries are mixed into the personal reflection, showing how preparing food in a different geographic location can change the experience of preparation and eating. In addition to personal experience, included is a synthesis of research done on the effects of sharing a plate or a meal on negotiations tactics, how eating the same food increases trust, the ways in which food sharing is an act of social intimacy, and how it can build community. Food is an important part of family connection, a tool in many rituals such as Sunday dinners or breaking bread, a critical aspect of many religions, and is tied to the celebration of both birth and death in cultures around the globe. We all need to eat; food is the great commonality among people.

Optical Communications are at a high point of interest by the space engineering community. After successful projects like the Lunar Laser Communications Demonstration (LLCD), NASA has become interested in augmenting their current Deep Space Network (DSN) with optical communication links. One such link is Deep Space Optical Communications (DSOC) which will be launching with the Psyche mission. To gain a full understanding of the advantages of this network, this thesis will go over the history and benefits of optical communications both on Earth and in space. This thesis will then go in depth on NASAs DSOC project through an algorithmic implementation of the communications channel.

Description
Laboratory animals represent an invaluable, yet controversial, resource in the field of biomedical research. Animal research has been behind many influential discoveries in the field of emerging therapeutics. They provide the link between the theory of the lab bench and the functional application of medicine to influence human health. The use of animals in research is a consideration which must be heavily weighed, and the implementation must be carried out at a very high standard in order to retain research integrity and responsibility. We are in the process of conducting an experiment using laboratory mice to demonstrate cancer treatment using vaccinia (VACV) mutants as a possible oncolytic therapy for certain strains of melanoma. VACV is a double-stranded DNA poxvirus with a large and easily altered genome. This virus contains many genes dedicated to immune evasion, but has shown sensitivity to cell death by necroptosis in mouse studies (5). We have identified the absence of the kinase RIP3 which is vital in the necroptosis pathway as a potential target for oncolytic therapy using VACV mutants in specific strains of melanoma. Multiple groups of SCID Beige mice were inoculated with different melanoma cell lines and observed for tumor growth. Upon reaching 1 cm3 in volume, tumors were injected with either VACV- Δ83N, VACV- Δ54N, or PBS, and observed for regression. It was hypothesized that melanoma tumors that are RIP3-/- such as the MDA5 cell line will show regression, but melanoma tumors that are RIP3-positive and capable of necroptosis, such as the 2427 cell line, will resist viral replication and continue to proliferate. Our results so far tentatively support this hypothesis, but the data collection is ongoing. Strict and specific protocols with regard to the ethical and responsible use of mice have been implemented and upheld throughout the experiment. Animals are closely monitored, and if their quality of life becomes too poor to justify their continued use in the experiment, they are humanely euthanized, even at the expense of valuable data. The importance of commitment to a high ethical standard is pervasive throughout our work. Animals represent an invaluable contribution to research, and it is important to maintain high standards and transparency with regard to their use. Education and engagement in critical discussions about the use and care of animals in the laboratory contribute to the overall merit and legitimacy of biomedical research in the public and professional eye as a whole, and give legitimacy to the continued use of animals as models to advance science and health.

Description
For this project, I use qualitative textual analysis to compare the differences and/or similarities between (1) how the former residents of Tempe’s historic San Pablo barrio (1872-1955) conveyed their sense of place, meaning, and displacement in oral and written histories and (2) how Tempe’s Anglo residents at the time of San Pablo’s occupation and dissolution conveyed their sense of the place, meaning, and displacement of San Pablo in newspaper articles. I have located my investigation of any perceived or lacking disparities between how these two groups perceived San Pablo’s place and meaning within the context of San Pablo’s dissolution and the displacement of its residents in the mid 1950s. As I follow the process through which some communities are able to suppress, take over, and erase others from dominant narratives and political decisions without any perceived consequences, I will bring to the foreground the emotional impact of place and displacement in order to highlight how the former residents of ‘erased’ communities make sense of and respond to their displacement.

This project, Building the Backdrop, Expanding Perspectives on Sustainability, is a sculpture of a desert sunset that seeks to explore important sustainability issues and highlight the beauty in sustainable practices. Constructed for an honors thesis project at Arizona State University, the primary medium used was cardboard repurposed from package deliveries to bring attention to modern overconsumption of packaging materials and showcase our ability to give new life to traditionally single use materials. I invite you to interact with the piece by sharing photos of yourself in front of it to help spread its message and exploring the resources shared along with the sculpture.

Description
We discuss the intricate and puzzling concept of quantum entanglement, and not only
define it but also consider the implications of the behaviors of entangled particles. The ability of
these particles to provide instantaneous information about their entangled counterparts sparked a debate among physicists as to whether or not these particles had definite quantities before
measurement, and whether or not their behaviors could be explained by a local hidden-variables
theorem. Mermin’s gedanken demonstration for a two-particle entangled system is introduced, as well as Bell’s inequality, and an explanation of how a pair of two entangled particles violate this inequality. Additionally, we also discuss various experimental verifications that were able to use Bell’s inequality to verify the expected quantum mechanical results for their entangled systems.

Description
Terrestrial hermit crabs serve an incredibly important ecological role in seed dispersal and as decomposers along coastal shorelines. They have also become quite popular in the commercial pet trade, with one species, Coenobita clypeatus, being particularly favored. Typically, these hermit crabs are easily captured and removed from the wild with little protection in their native ranges. In Hermitage Bay, Tobago, there is little information about the population numbers, composition, shell preference, and substrate preference of C. clypeatus in their native habitat. In this study, we estimated population size, gastropod shell preferences, and substrate preference conditions when clustering. We conducted mark re-capture surveys in March, July, and December 2023 and collected morphological data from captured hermit crabs. Our results indicate that the estimated population was highest in July, with the variation being significant when using the Schnabel mark re-capture estimation formula. The most common overall shell type, Columbella mercatoria (West Indian Dove Shell), was prevalent among the smaller sized, younger hermit crabs; while the larger hermit crabs preferred Cittarium pica (West Indian Top Shell). The most preferred substrate for these terrestrial hermit crabs were areas with a mixture of sand and dirt, with high amounts of vegetation and leaf waste and low amounts of human litter. These results suggest a predominantly young population and that beach cleanups should focus on removing human litter entirely, while leaving leaf waste and other fallen logs and branches and not using the collected decomposing plant matter for bonfires. This can help maintain a healthy hermit crab population that continues to benefit the coastlines in Tobago as well as other ecosystems.
