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.

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
The story of graphene truly began in what was simply a stub in the journal Physical Review not two years after the end of World War II. In 1947, McGill University physicist P.R. Wallace authored “The Band Theory of Graphite” and attempted to develop a foundation on which the structure-property relationship of graphite could be explored; he calculates the number of free electrons and conductivity of what he describes as “a single hexagonal layer” and “suppos[es] that conduction takes place only in layers” in bulk graphite to predict wave functions, energies at specific atomic sites in the hexagonal lattice, and energy contours using a tight binding approximation for a hypothesized version of what we now call ‘armchair-style’ graphene. While Wallace was the first to explore the band structure and Brillouin Zones of single-layer graphite, the concept of two-dimensional materials was not new. In fact, for years, it was dismissed as a thermodynamic impossibility.
Everything seemed poised against any proposed physical and experimental stability of a structure like graphene. “Thermodynamically impossible”– a not uncommon shutdown to proposed novel physical or chemical concepts– was once used to describe the entire field of proposed two-dimensional crystals functioning separately from a three-dimensional base or crystalline structure. Rudolf Peierls and Lev Davoidovich Landau, both very accomplished physicists respectively known for the Manhattan Project and for developing a mathematical theory of helium superfluidity, rejected the possibility of isolated monolayer to few-layered crystal lattices. Their reasoning was that diverging thermodynamic-based crystal lattice fluctuations would render the material unstable regardless of controlled temperature. This logic is flawed, but not necessarily inaccurate– diamond, for instance, is thermodynamically metastable at room temperature and pressure in that there exists a slow (i.e. slow on the scale of millions of years) but continuous transformation to graphite. However, this logic was used to support an explanation of thermodynamic impossibility that was provided for graphene’s lack of isolation as late as 1979 by Cornell solid-state physicist Nathaniel David Mermin. These physicists’ claims had clear and consistent grounding in experimental data: as thin films become thinner, there exists a trend of a decreasing melting temperature and increasing instability that renders the films into islands at somewhere around ten to twenty atomic layers. This is driven by the thermodynamically-favorable minimization of surface energy.

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.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by a wide range of symptoms and severities, affecting communication, behavior, and social interactions. With the prevalence of ASD rising to affect nearly 1 in 36 children in the United States, understanding and addressing the multifaceted needs of those with ASD is increasingly critical. This review explores the interplay between genetic, environmental, and immune factors in the onset of ASD, focusing on metabolic dysfunctions and the role of the gut-brain axis. Emerging research highlights the significance of abnormal metabolites and gut microbiota imbalances in contributing to the pathophysiology of ASD, suggesting that these factors may influence neurological function and behavior through modulating immune responses.
Recent analyses have uncovered metabolic disturbances in ASD, affecting amino acid metabolism, glutathione metabolism, glycolysis and the TCA cycle, homocysteine metabolism, ketone body synthesis, and lipid metabolism. These disturbances offer insights into how metabolic dysfunctions may contribute to the neurological and behavioral features of ASD. Furthermore, the gut microbiota's role in immune responses and the controversial impact of antibiotic use on gut flora composition is important to the complexity of ASD and the need for a nuanced understanding of treatment effects.
This review delves into the current understanding of metabolic dysfunctions in children with ASD, emphasizing the critical role of gut microbiota and the impact of antibiotic use. Specifically, this review discusses SCFAs, para-cresol, amino acid metabolites, and glutathione and their respective specific treatments. It also explores the potential of vitamin/mineral supplementation as a therapeutic strategy, highlighting significant improvements in metabolic markers and behavioral symptoms associated with ASD. The findings from key studies, including those by Adams et al., suggest that targeted nutritional interventions and careful management of gut health could offer promising avenues for improving the quality of life for individuals with ASD. The review also acknowledges the need for further research to confirm the long-term effects of these interventions and to develop personalized treatment approaches that consider the unique needs in individuals with ASD.

Chisholm’s contrary-to-duty paradox raises important questions for formulating instances of conditional obligation. Angelika Kratzer is one linguist whose theories offer some solutions to these questions; more generally, she provides theories for how we should represent modals, conditionals, and other features of language in terms of functions. Though her theories are incredibly useful, they do not adequately represent the Chisholm scenario as a whole. In this paper, I attempt to address this shortcoming in her theory. First, I present and explain some of Kratzer’s main ideas. Then, I explain how her theory offers a solution to Chisholm’s Paradox, and examine a shortcoming of her theory as presented– specifically, the fact that her theory does not account for the importance of different norms in relation to each other. Finally, with the Chisholm situation as a backdrop, I offer my own contribution to her theory. Namely, I propose assigning an importance “score” to each norm, and factoring that “score” into the machinery of Kratzer’s theory.

Immediate early genes (IEGs) are the first set of genes to be transcribed in a cell in response to stimuli; their expression is quick and is not protein synthesis dependent. Neurons are activated in response to external stimuli, causing a rapid increase in IEG expression in the brain. IEG proteins go on to affect fundamental neurobiological processes that are known to be dysfunctional in patients with psychiatric disorders, and therefore IEGs have been connected to the pathogenesis of schizophrenia. Early growth response (Egr) genes are immediate early gene transcription factors (IEG-TFs) that are expressed in response to an altered environment. The IEG-TFs, early growth response 1 (EGR1) and early growth response 3 (EGR3) are necessary for processes such as memory and synaptic plasticity; lack of function in these genes causes dysfunction or disruption of these processes. We wanted to observe if increasing the function of Egrs by overexpressing them will lead to improved memory. To help further understand how behavior is affected by the overexpression (O/E) of Egr1 in response to stimuli, the AAV-ESARE-Egr1 virus was developed to be injected in the hippocampus of mice. In the hippocampus of wild-type (WT) mice, cells that are active endogenously express Egr1. The virus was created using the synaptic activity-response element (SARE), an element discovered on the promoter of the IEG activity-regulated cytoskeleton-associated (Arc) gene by our collaborators in Japan. Using an “enhanced” form of SARE (ESARE), our newly created virus acts to overexpress Egr1 only in response to activity in the hippocampus; we can then observe if the behavioral processes associated with Egr1 will improve. First, this project aims to validate that the AAV-ESARE-Egr1 virus is increasing Egr1 expression in the active hippocampal dentate gyrus (DG) granule cells of WT mice, and only in response to activity. The activity is in the form of a physiological stimulus, environmental enrichment (EE) and a non-physiological stimulus, electroconvulsive seizures (ECS). After confirming these characteristics of AAV-ESARE-Egr1 we can then use it to observe if EGR1 O/E improves the memory of mice.
