Computational_Electromagnetic Modeling (Cem) Of Foliage Penetration (Fopen), Monica R. Jaramillo

Electrical and Computer Engineering ETDs

Foliage penetration (FOPEN) radar at lower frequencies (UHF, VHF) is a well-studied area with a wide set of contributions. However, there is growing interest in using higher Ku-band frequencies (12-18 GHz frequency range) for FOPEN. In particular, the reduced wavelength sizes (centimeters range) provide some key saliencies for developing more optimized foliage detection solutions. The disadvantage is that exploiting Ku-band for FOPEN is complicated because higher frequencies have much more pronounced scattering effects due to their smaller wavelengths. Despite these challenges, certain foliage characteristics and signal parameters can help improve electromagnetic (EM) wave penetration in the Ku-band such as foliage …

Automatic Generation And Novel Validation Of Patient-Specific, Anatomically Inclusive Scoliosis Models For Biomechanics-Informed Surgical Planning, Austin Tapp, Michel Audette, James Bennett

College of Engineering & Technology (Batten) Posters

Scoliosis is an abnormal spinal curvature of greater than 10 degrees. Severe scoliotic deformities are addressed with highly invasive procedures: anterior or posterior spinal fusion approaches. This invasiveness is due, in part, to the constraints of current surgical planning, which utilizes computed tomography (CT) scans unable to discern spinal ligaments that are dissected to make the spine sufficiently compliant for correction. If localization of ligaments and soft tissues were achieved pre-operatively, corrective procedures could become safer and more efficient by using finite element (FE) biomechanical simulations to determine decreased incidences of ligament releases. This research aims to achieve ligament localization …

Genetically Screening For Gain Of Function Mutations In Telomerase Rna, Jose Childers

2021 Celebration of Student Scholarship - Oral Presentations

Telomeres are DNA structures located at the ends of linear chromosomes. They function, in part, to allow DNA ends to be copied before cells divide. Since the standard DNA replication machinery can’t fully copy telomeres, most eukaryotic cells require the vital ribonucleoprotein enzyme telomerase. Telomerase is composed of a TERT (telomerase reverse transcriptase protein) and telomerase RNA. As we age, telomeres shorten since most human cells do not express telomerase. If telomeres grow too short, it triggers a cell-cycle arrest known as senescence, which can ultimately result in cell death. On the other hand, >85% of human cancers show over-expression …

Comparing Growth Of Mutant Strains Of Acinetobacter Baumannii To Wild Type After Treatment With Mitomycin C, Kaylee Compton, Deborah Cook

2021 Celebration of Student Scholarship - Oral Presentations

In Acinetocbacter baumannii bacteria, an error-prone DNA damage repair response is induced by the self-cleavage of the UmuDAb protein. Previous experiments indicating that a ddrR mutant becomes growth sensitive after DNA damage suggested that ddrR is also involved in this process. To explore this relationship, eight mutant strains of A. baumannii were made with different combinations of mutations in either ddrR and/or the adjacent gene, A1S_3662. Our experiment compared the growth of wild type cells to strains containing various mutations: DC4 (no gene mutations, just an antibiotic resistance marker, Kanr), DC5 (stop codon mutation in ddrR), and DC6 (both the …

“The Never Ending Story:” Circularizing Ch. Viii In Saccharomyces Cerevisiae, Chisom Iloegbunam

2021 Celebration of Student Scholarship - Oral Presentations

Chromosomes are molecules of DNA that hold large quantities of genetic material in an organism. Generally in nature, eukaryotic chromosomes are linear while prokaryotic chromosomes are circular. Since they are linear, eukaryotic chromosomes possess telomeres, or repetitive nucleotide sequences, on their ends. This significant difference in structure requires different additions to the basic replication process. In prokaryotes, replication starts at a single point on the chromosome and continues until the whole chromosome has been copied. In eukaryotes, replication happens in fragments with multiple starting points. Because of this more complicated replication, the free 3’ ends cannot be fully copied. Unchecked, …
