Are Students Actually Learning What You Think They Are? An Exploration Into The Educational Outcomes Of Course Based Undergraduate Research Labs, Matilda Dumaine, Jacob Saadoun
Biology Presentations
It is important to understand whether students are acquiring intended educational objectives. A course-based undergraduate research experience (CURE) lab seeks to blend the logistical ease and accessibility of college courses with the educational benefits of research experiences. By employing inquiry-based teaching methods, CURE labs enable students to collaborate in a group setting under the guidance of a faculty member, engaging in hands-on research. This project studies how educational outcomes of CURE labs can be measured. CURE labs may improve anything from technical lab skills, to scientific literacy, to persistence in science. These short-, middle-, and long-term goals may be measured …
Sentiment Analysis Before And During The Covid-19 Pandemic, Emily Musgrove
Sentiment Analysis Before And During The Covid-19 Pandemic, Emily Musgrove
Mathematics Summer Fellows
This study examines the change in connotative language use before and during the Covid-19 pandemic. By analyzing news articles from several major US newspapers, we found that there is a statistically significant correlation between the sentiment of the text and the publication period. Specifically, we document a large, systematic, and statistically significant decline in the overall sentiment of articles published in major news outlets. While our results do not directly gauge the sentiment of the population, our findings have important implications regarding the social responsibility of journalists and media outlets especially in times of crisis.

Improving The Efficiency Of Liquid-Hydrogen Simulation Via Event Storage, Jake Kosa
Physics and Astronomy Summer Fellows
We contributed to the analysis of gamma-ray spectroscopy data collected at the Facility for Rare Isotope Beams at Michigan State University by speeding up the UCGretina simulation code, used in the analysis and planning of experiments. Simulating beam-target interactions in a liquid-hydrogen target system is a time intensive task, even when parallelized. In the process of analyzing data, a large number of simulations must be run for different gamma-ray energies, target positions, and lifetimes of excited states. We are addressing the most computationally intensive component of the simulations by adding the ability to simulate a large sample of beam particles …

Carbon Nanotubes Animated, Nicholas Onyemeke
Chemistry Summer Fellows
In this project, I implemented the knowledge about carbon nanotubes into an animated short. The animated short is meant to simplify the research so that anyone can understand regardless of their background in science. The research I did was on how nanotubes can be used in the medical field as a measure to inhibit bacteria growth. A nanotube dye solution was synthesized to inoculate bacteria along with an antibiotic solution with the nanotubes. This was done to observe how well the nanotubes can inhibit bacteria growth without the need for a drug compared to the effectiveness when it has a …

Applying Bioactive Glass Beads For Long-Term Drug Delivery, Marie O. Sykes, Rashi Sharma
Applying Bioactive Glass Beads For Long-Term Drug Delivery, Marie O. Sykes, Rashi Sharma
Physics and Astronomy Presentations
Bioactive glass beads have been used to distribute medicine over extended periods of time in limited uses. They can be engineered to have a porous and hollow structure, and using Mo-Sci's OL-GL 1756b (1756b), the fundamental notion of dosage distribution can be tested in preparation to design the optimal glass for medicine distribution. A few key factors in this is how long does it take the liquid to release from the beads, how do the beads decay, and how well the glass can bond to human tissue. This research demonstrates the capacities of the 1756b type as a promising start …
Nviz: Unraveling Neural Networks Through Visualization, Kevin Hoffman
Nviz: Unraveling Neural Networks Through Visualization, Kevin Hoffman
Mathematics and Computer Science Presentations
The growing utility of artificial intelligence (AI) is attributed to the development of neural networks. These networks are a class of models that make predictions based on previously observed data. While the inferential power of neural networks is great, the ability to explain their results is difficult because the underlying model is automatically generated. The AI community commonly refers to neural networks as black boxes because the patterns they learn from the data are not easily understood. This project aims to improve the visibility of patterns that neural networks identify in data. Through an interactive web application, NVIZ affords the …
R Text Analysis For Adam Smith Cie Selected Works, Charlotte Grahame
R Text Analysis For Adam Smith Cie Selected Works, Charlotte Grahame
Mathematics and Computer Science Presentations
Text mining and text analysis is a way of understanding text documents using r coding that is more frequently used for numbered data. It helps with understanding portions of the text and drawing conclusions from there. This research looks specifically at the Adam Smith required documents that are used in the CIE course designated for freshmen. It looks at sentiments of the documents, including word sentiment, sentence sentiment, page and overall document sentiment as well. It provides visuals of word clouds to portray word frequency, tf-idf (which is explained in the presentation) and bigram analysis.

An Analysis Of Decolonization Efforts In Urban Agriculture: A Pathway To Indigenous Food Sovereignty And Cultural Revitalization, Sarah Fisher
Environment and Sustainability Summer Fellows
My research focuses on applications of urban agriculture, relationships between Indigenous peoples and community-based agriculture projects, and decolonizing food systems. I provide insight on colonialist tendencies, or ways in which the marginalization of Indigenous peoples is deeply entrenched within government, educational, and other leadership settings, as a way to evaluate and restructure urban agriculture projects to serve, represent and heal Native communities. Conventional urban agriculture has many known benefits, including its capacity for food production; however, the extent to which Indigenous communities participate in and benefit from urban agriculture has not been widely studied. Ongoing exclusion of Indigenous peoples from …

The Dope Distance Is Sic: A Stable, Informative, And Computable Metric On Ordered Merge Trees, Jose Arbelo, Antonio Delgado, Charley Kirk, Zach Schlamowitz
Mathematics Summer Fellows
When analyzing time series data, it is often of interest to categorize them based on how different they are. We define a new dissimilarity measure between time series: Dynamic Ordered Persistence Editing (DOPE). DOPE satisfies metric properties, is stable to noise, is as informative as alternative approaches, and efficiently computable. Satisfying these properties simultaneously makes DOPE of interest to both theoreticians and data scientists alike.
Resonant Energy Exchange In Ultracold Rydberg Atoms, Samantha Grubb, Alan Okinaka
Resonant Energy Exchange In Ultracold Rydberg Atoms, Samantha Grubb, Alan Okinaka
Physics and Astronomy Summer Fellows
Ultracold Rydberg atoms serve as good systems in which resonant dipole-dipole interactions can be observed. The goal of our work is to design a simulation in which energy exchange among many nearly evenly spaced energy levels is observed. These observations are useful for understanding the time evolution of complicated quantum systems, and have applications in quantum computing and simulating. We are utilizing a supercomputer to run our simulation as well as studying the system experimentally. Once we obtain simulated results, we plan to compare them with the results obtained in a lab.
Automatic Data Aggregation To Assist In The Systematic Classification Of Small Lunar Craters, Liam Powers
Automatic Data Aggregation To Assist In The Systematic Classification Of Small Lunar Craters, Liam Powers
Physics and Astronomy Summer Fellows
Crater counting has been one of the dominant methods of characterizing surfaces of planetary bodies in the absence of material samples. Unfortunately, counts often rely on the subjective expertise of the counter, which limits the volume of reliable data that is accessible to researchers. Our work seeks to develop a quantifiable method of classifying individual craters within a count population to better determine a given crater’s age and origin. Recommendations are then generated in order to increase the accuracy of human counters, and improve the efficiency of the counting process. Preliminary work on the Moon uses LRO LOLA elevation data, …

An Exploration Of A Year At The Ursinus Food Forest, Victoria Bearden
Environment and Sustainability Presentations
The Ursinus Food Forest began a commitment to a new form of sustainable land management at Whittaker Environmental Research Station. This management integrates lessons from urban agriculture, urban forestry, and agroforestry (see Clark & Nichols 2013) with principles of permaculture (Jacke et al 2005). Begun in 2017, and this past fall marked 2 years since the planting of phase one in 2019. In the fall of 2021 students, faculty, facilities, and volunteers planted the second phase of the food forest site, which added 7 new food producing species. Including this, many projects were created to enhance the site throughout the …
Amplification Of Hidden Periodic Motions In 3d Videos, Thomas Boccuto, Seraiah Kutai, Kristen Mosley, Samuel Kirk
Amplification Of Hidden Periodic Motions In 3d Videos, Thomas Boccuto, Seraiah Kutai, Kristen Mosley, Samuel Kirk
Mathematics Summer Fellows
Ordinary videos capture a surprising amount of hidden, visually imperceptible information. For instance, videos of peoples' faces may capture color changes in the skin and artery motion from heartbeats, while videos of mechanical systems can capture subtle vibrations indicating imminent failure. Algorithms can extract and exaggerate these signals for visualization on top of the original videos. In particular, Eulerian magnification algorithms sidestep the need to track hidden motions directly and instead devise multiscale bandpass filters to amplify signals in local spatial regions. In this work, we extend these techniques beyond color videos to geometric video data captured by 3D depth …
Advancement In Infrared Optics Through The Exploration Of Solution Derived Arsenic Selenide (As2se3) Thin Films, Annabella Orsini
Advancement In Infrared Optics Through The Exploration Of Solution Derived Arsenic Selenide (As2se3) Thin Films, Annabella Orsini
Physics and Astronomy Summer Fellows
There are great opportunities for advancement in the realm of infrared (IR) optics through the use of chalcogenide glasses (ChGs). The development of IR optics using ChGs is important for applications in search and rescue operations, firefighting efforts, medical imaging, and satellites. Instead of creating bulky, expensive, single crystal IR glasses, ChGs can be deposited as thin films by solution derived (SD) spin or dip coating. Our research takes a multidisciplinary approach to investigate ChGs thin films using physics, chemistry, optics, and materials science.
Urban Forests And Their Potential To Combat Food Insecurity: Analyzing Street Trees In Baltimore, Md For Their Edibility, Victoria Bearden
Urban Forests And Their Potential To Combat Food Insecurity: Analyzing Street Trees In Baltimore, Md For Their Edibility, Victoria Bearden
Environment and Sustainability Summer Fellows
Food insecure environments, in which residents lack consistent access to nutritious food materials, can occur in urban settings. Literature on urban forests suggests that trees can provide a range of provisioning ecosystem services, including edible uses. We consider this to determine if street trees in Baltimore, Maryland have the potential to provide nutritious food materials to address food insecurity in Healthy Food Priority Areas (HFPA), designated by Johns Hopkins Center for a Livable Future.

Urban Forests And Their Potential To Combat Food Insecurity: Analyzing Foods From Street Trees In New York City, Ny, Kristen Cooney
Environment and Sustainability Summer Fellows
There is growing recognition that urban forests have the potential to combat food insecurity via their edible parts, namely fruits, berries, and nuts. Many tree species commonly planted in urban spaces have edible parts that may fulfill the nutritional needs of city residents that are food insecure, but no one has analyzed the value of city street trees to understand this potential. I analyzed New York City’s street trees by each species and their edible parts to measure this potential.

54fe(D,P)55fe Single Neutron Transfer Presentation, Matthew Quirin, Raymond Saunders
Physics and Astronomy Presentations
During our summer research at the John D Fox Laboratory, we used the 9 MV Tandem van de Graaff accelerator and the Super Enge Split-Pole Spectrograph to make measurements of the neutron transfer reaction 54Fe(d,p) 55Fe to observe and explore excited states of 55Fe and shell structure beyond the magic number N=28. We have created momentum spectra and angular distribution plots of the protons from the reaction which will be analyzed to determine the angular momentum values of states and single-neutron energies in 55Fe in an effort to better understand nuclear structure.

Towards The Homotopy Type Of The Morse Complex, Connor Donovan
Towards The Homotopy Type Of The Morse Complex, Connor Donovan
Mathematics Summer Fellows
Mathematicians have long been interested in studying the properties of simplicial complexes. In 1998, Robin Forman developed gradient vector fields as a tool to study these complexes. Having gradient vector fields to study these simplicial complexes, in 2005, Chari and Joswig discovered the Morse complex, a complex consisting of all gradient vector fields on a fixed complex. Although the Morse complex has been studied since 2005, there is little information regarding its homotopy type for different simplicial complexes. Pursuing our curiosity of the topic, we extend a result by Ayala et. al., stating that the pure Morse complex of a …
