A Preliminary Survey On The Biodiversity Of Wasps In Eastern Kentucky, Lorien Molstad, Zoe Baker, Julia Fitzpatrick, Bethany Lucio, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

Biodiversity is the measure of variability of interactions between living organisms within an area. Biodiversity contributes significantly to the production of different life sustaining resources and supports a diversity of ecological life. A greater biodiverse area can help maintain environmental balance and maintain ecological diversity and health. There are multiple economic, cultural, and scientific reasons as to why biodiversity is important. When assessing biodiversity, mammals and birds are commonly used as surrogates. The problem with mammals and birds is that there are relatively few species and relatively few individuals in an area, so quantitative assessment can be difficult. However, insects …

Survey Of Spiders Within Eastern Kentucky, Mercy Hailu, Bailey Bullock, Joshua Hicks, Eliana Eldridge, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

Biodiversity is known to be the variation of living organisms compromising several levels, beginning from genes, then species, communities, then finally ecosystems. Biodiversity is crucial in maintaining ecological balance, boosting ecosystem productivity, and determining the quality of ecosystem services such as pest management in agriculture. Being aware of biodiversity's importance can also help with the prevention of continuous threats to biodiversity and be best prepared to manage conservation challenges. Typically, mammals, birds, and plants are used to assess biodiversity. However, spiders may be effective in indicating environmental change because they are taxonomically quite diverse, species fill a variety of ecological …


Creating The First Genetically Engineered Eukaryote With Circular Chromosomes, Duncan Mcginnis, Melissa Mefford Apr 2022

Creating The First Genetically Engineered Eukaryote With Circular Chromosomes, Duncan Mcginnis, Melissa Mefford

2022 Celebration of Student Scholarship - Poster Presentations

Prokaryotes and eukaryotes differ in their chromosome structure; prokaryotes have a single circular chromosome, while eukaryotes have multiple circular chromosomes. Linear chromosomes are more complex than circular ones and create problems for eukaryotes. Many of these issues are solved by telomeres—long, repetitive sequences of DNA found on the ends of most eukaryotic chromosomes. They protect the ends from harm and limit how many times a cell can divide. Two of our greatest medical challenges, cancer and aging, are closely related to telomeres; most cancers upregulate telomerase, and aging human cells display shorter telomeres. To investigate the evolution and function of …

2022 Celebration of Student Scholarship - Poster Presentations

Fungi play a key role in the terrestrial carbon cycle, soil formation, and overall plant growth as terrestrial decomposers (1, 2). Thus, the study of fungi, especially in the fossil record, is critical to understanding how fungal assemblages will react to future warming events. Fossil fungi provide a large-scale, long-term dataset unavailable from modern records, allowing for the generation of viable paleoclimate reconstructions and predictions (3, 4). Despite their importance and advantages in forming ecological and climatological interpretations, deep-time fungi have been underutilized (3). The Fungi in a Warmer World (FiaWW) project aims to deliver the first global view of …

2022 Celebration of Student Scholarship - Poster Presentations

Microfungi are a vital part of ecosystems as they help with key processes, such as carbon and nutrient cycling, especially through the actions of mycorrhizal and saprotrophic members (Nuñez Otaño et al., 2015, 2021; Willis et al., 2018). Microfungi can also be good indicators of plant biodiversity in an area because many fungal taxa are host-specific (Rutten et al., 2021; Francioli et al., 2021; Hu et al., 2021; Wijayawardene et al., 2022 ). Despite being crucial components in ecosystems, they are often overlooked. In the fossil record, microfungi have a high preserva􀆟on rate and they are often preserved close to …

Lyapunov-Based Economic Model Predictive Control For Detecting And Handling Actuator And Simultaneous Sensor/Actuator Cyberattacks On Process Control Systems, Henrique Oyama, Dominic Messina, Keshav Kasturi Rangan, Helen Durand

Chemical Engineering and Materials Science Faculty Research Publications

The controllers for a cyber-physical system may be impacted by sensor measurement cyberattacks, actuator signal cyberattacks, or both types of attacks. Prior work in our group has developed a theory for handling cyberattacks on process sensors. However, sensor and actuator cyberattacks have a different character from one another. Specifically, sensor measurement attacks prevent proper inputs from being applied to the process by manipulating the measurements that the controller receives, so that the control law plays a role in the impact of a given sensor measurement cyberattack on a process. In contrast, actuator signal attacks prevent proper inputs from being applied …

Automatic Speech Recognition (ASR) systems can be trained to achieve remarkable performance given large amounts of manually transcribed speech, but large labeled data sets can be difficult or expensive to acquire for all languages of interest. In this paper, we review the research literature to identify models and ideas that could lead to fully unsupervised ASR, including unsupervised sub-word and word modeling, unsupervised segmentation of the speech signal, and unsupervised mapping from speech segments to text. The objective of the study is to identify the limitations of what can be learned from speech data alone and to understand the minimum …


Clostridioides Difficile Spore Production In Response To Antibiotic And Immune Stress, Adenrele Oludiran, Erin B. Purcell Apr 2022

Clostridioides Difficile Spore Production In Response To Antibiotic And Immune Stress, Adenrele Oludiran, Erin B. Purcell

College of Sciences Posters

Clostridioides (Clostridium) difficile, an anaerobic, spore-forming Gram-positive pathogenic bacterium, is a major cause of hospital-acquired infections and can persist as surface-attached biofilms for protection from antibiotic and immune stress. C. difficile can form biofilms as a single species or with other anaerobic intestinal bacteria. The environmental signals that cause individual cells to secrete toxins, form biofilms, or develop into spores that can spread the infection to new patients are unknown. In these studies, we investigate bacterial responses to different stress. Antimicrobial host-defense peptides (HDPs) produced by animal immune systems are promising candidates to develop novel therapies for bacterial infection …

Hyperbolic Quotients Of Projection Complexes, Matt Clay, Johanna Mangahas Apr 2022

Hyperbolic Quotients Of Projection Complexes, Matt Clay, Johanna Mangahas

Mathematical Sciences Faculty Publications and Presentations

This paper is a continuation of our previous work with Margalit where we studied group actions on projection complexes. In that paper, we demonstrated sufficient conditions so that the normal closure of a family of subgroups of vertex stabilizers is a free product of certain conjugates of these subgroups. In this paper, we study both the quotient of the projection complex by this normal subgroup and the action of the quotient group on the quotient of the projection complex. We show that under certain conditions the quotient complex is δ-hyperbolic. Additionally, under certain circumstances, we show that if the original …

Lattice Optics Optimization For Recirculatory Energy Recovery Linacs With Multi-Objective Optimization, Isurumali Neththikumara, Todd Satogata, Alex Bogacz, Ryan Bodenstein, Arthur Vandenhoeke

College of Sciences Posters

Beamline optics design for recirculatory linear accelerators requires special attention to suppress beam instabilities arising due to collective effects. The impact of these collective effects becomes more pronounced with the addition of energy recovery (ER) capability. Jefferson Lab’s multi-pass, multi-GeV ER proposal for the CEBAF accelerator, ER@CEBAF, is a 10- pass ER demonstration with low beam current. Tighter control of the beam parameters at lower energies is necessary to avoid beam break-up (BBU) instabilities, even with a small beam current. Optics optimizations require balancing both beta excursions at high-energy passes and overfocusing at low-energy passes. Here, we discuss an optics …

A Spatially And Temporally Second Order Method For Solving Parabolic Interface Problems, Kumudu Gamage, Yan Peng

College of Sciences Posters

Parabolic interface problems have many applications in physics and biology, such as hyperthermia treatment of cancer, underground water flow, and food engineering. Here we present an algorithm for solving two-dimensional parabolic interface problems where the coefficient and the forcing term have a discontinuity across the interface. The Crank-Nicolson scheme is used for time discretization, and the direct immersed interface method is used for spatial discretization. The proposed method is second order in both space and time for both solution and gradients in maximum norm.

Recent advancements in high-throughput technologies have enabled simultaneous inference of thousands of genes. With the abundance of public databases, it is now possible to rapidly access the results of several genomic studies, each of which includes the significance testing results of a large number of genes. Researchers frequently aggregate genomic data from multiple studies in the form of a meta-analysis. Most traditional meta-analysis methods aim at combining summary results to find signals in at least one of the studies. However, often the goal is to identify genes that are differentially expressed in a consistent pattern across multiple studies. Recently, a …

Physics-Informed Neural Networks (Pinns) For Dvcs Cross Sections, Manal Almaeen, Jake Grigsby, Joshua Hoskins, Brandon Kriesten, Yaohang Li, Huey-Wen Lin, Simonetta Liuti, Sorawich Maichum

College of Sciences Posters

We present a physics informed deep learning technique for Deeply Virtual Compton Scattering (DVCS) cross sections from an unpolarized proton target using both an unpolarized and polarized electron beam. Training a deep learning model typically requires a large size of data that might not always be available or possible to obtain. Alternatively, a deep learning model can be trained using additional knowledge gained by enforcing some physics constraints such as angular symmetries for better accuracy and generalization. By incorporating physics knowledge to our deep learning model, our framework shows precise predictions on the DVCS cross sections and better extrapolation on …


Telomerase Activity Enhancement In Saccharomyces Cerevisiae, Mackenzie Neal, Hailey Rietz, Melissa Mefford Apr 2022

Telomerase Activity Enhancement In Saccharomyces Cerevisiae, Mackenzie Neal, Hailey Rietz, Melissa Mefford

2022 Celebration of Student Scholarship - Poster Presentations

Telomeres are located at the ends of eukaryotic linear chromosomes and are composed of repeated nucleotide sequences. One of their main functions is to protect chromosomal ends from being damaged. Telomeres cannot be completely copied during DNA replication so they gradually shorten during each replication cycle in what is known as the “end replication problem”. To counteract this problem, the RNA dependent enzyme complex telomerase works to extend telomeres and help protect the ends of chromosomes. Telomeres and the telomerase enzyme are heavily involved in the aging process and cancer progression. Telomeres gradually shorten with age and eventually become so …

Development Of Anti-Cancer Small Molecules To Inhibit The Base Excision Repair (Ber) Pathway By Binding Apyrimidinic/Apurinic (Ap) Sites In Dna, Ellen S. Ledford, Robert M. Tackett, Elizabeth M. Thomas

2022 Celebration of Student Scholarship - Poster Presentations

Two of the main treatments available to patients with cancer are radiation and chemotherapy which both rely on the ability to induce DNA damage. One reason cancer deaths perpetrate is due to cancer resistance towards current cancer therapies. The Base Excision Repair (BER) pathway is involved in therapeutic resistance by utilizing DNA glycosylases that recognize and remove the damaged DNA base to leave the aldehyde. Apyrimidinic/Apurinic (AP) enzyme 1, APE1, then recognizes the aldehyde to trigger DNA repair. Alkoxyamines function to competitively covalently bind the aldehyde generated from the AP site. Once the aldehyde is covalently bonded with the alkoxyamine, …
