Energy Scaling And Frequency Ratios Of Particles And Constants, Alison Christina Menzmer, Donald Chakeres, Vola Andrianarijaona

Campus Research Month

We are exploring quantum aspects of various physical quantities (including Bohr radius, Rydberg constant, Planck time, and Hubble constant) and mass energies of elementary particles (including electron, neutron, and quarks). We express all physical units in an energy equivalence in Hertz, normalized to 1 Hz. Furthermore, the logarithms of these normalized energies are scaled by the logarithm of a chosen particle, which allows the generation of an Arrhenius plot exhibiting numerical structures. Our results presented in this poster show that the proton is a good candidate for an Arrhenius plot with partial fractions (1 + 1/n) and (1 - 1/n).

Biosensors For Biomedicine, Drake O'Leary

Miners Solving for Tomorrow Research Conference

This project investigated the use of engineered bacterial reporter systems to detect cellular stress responses associated with antibiotic activity. While constructs were successfully introduced and tested against known antibiotics, the reporter consistently produced a blue signal across conditions, limiting the ability to distinguish specific stress responses. This suggests issues such as leaky expression, insufficient regulatory control, or lack of specificity in the reporter design. Although results were inconclusive, this work highlights key challenges in developing reliable biosensors and provides a foundation for future optimization. Improving signal specificity and reducing background expression will be critical for enabling accurate characterization of antibiotic …

Asphalt Pavement Rejuvenation Investigated By Nuclear Magnetic Resonance Relaxometry, Catherine Skaggs

Miners Solving for Tomorrow Research Conference

Asphalt is a relatively inexpensive material commonly used for road pavements; however, asphalt ages from exposure to oxygen and UV radiation, leading to loss of elasticity, which leads to cracks and potholes. To slow or reverse asphalt aging, pavement preservation treatments are in use. It’s unclear whether these treatments truly rejuvenate the pavement structure or merely offer a short-term benefit. Nuclear Magnetic Resonance (NMR) relaxometry is an analytical technique that uses the recovery of excited nuclear magnetization as a parameter to gain insights into molecular environments. Recovery-time distributions gathered from asphalt materials show differences between regular and rejuvenated asphalt samples, …

Findings indicate that participation in RET boosts teachers’ curricular skills, professional networks, and …

Modeling Of Aggregate Losses Of Metastatic Cancer Using Katz Family (A, B, 0) Distributions, Cynthia M. Mwau, Howard Omukami

Institute for Educational Development, East Africa

The incidence of metastatic cancer over the years has gradually increased. This can be due to delayed quality treatment, attributed to insufficient funds. Models that can more accurately price cancer insurance policies incorporating its metastatic nature would enable insurance firms to develop affordable and profitable cancer insurance policies. Effectively marketed and reasonably priced insurance policies can enhance the uptake of cancer specific insurance, thereby alleviating the financial strain linked to cancer treatment. To capture the impact of metastatic cancer on overall cancerrelated losses, we construct Katz recursive models grounded in the Katz family of distributions, specifically the (a, b, 0) …

What Is Alive? Students’ Conceptions Of The Traits That Unite Living Organisms, Jeremy L. Hsu, Meredith A. Dorner, Kate Hill

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Biology is the study of life, but students often hold misconceptions about what it means to be alive, with children often associating life with movement. These misconceptions can lead to biases in what students think is alive, with younger children often not thinking of plants as living given their lack of discernable movement. Despite this past work, there have been no prior studies that we are aware of that have examined how students in introductory biology conceptualize what it means to be alive. Here, we draw upon a fortuitous dataset collected from an in-class activity done on the first day …
