Repressor Of The Sos Response Mechanism In Acinetobacter Baumannii Requires Helix-Formation And Dimerization For Its Dna-Binding Ability, Belinda Candra, Deborah Cook, Jenelle Hare Apr 2023

Repressor Of The Sos Response Mechanism In Acinetobacter Baumannii Requires Helix-Formation And Dimerization For Its Dna-Binding Ability, Belinda Candra, Deborah Cook, Jenelle Hare

2023 Celebration of Student Scholarship - Poster Presentations

After DNA damage, the multi-drug resistant pathogen Acinetobacter baumannii activates its SOS response, possibly allowing mutagenesis to occur by inducing multiple errorprone polymerases. A. baumannii uses the non-canonical repressor protein UmuDAb to repress operons of these polymerases. It has an N-terminal domain (NTD) with 2 helices (HTH1 & HTH2) whose sequences are needed for repression1. Like other bacterial SOS repressors such as LexA, UmuDAb dimerizes. BACTH analyses2 showed that UmuDAb forms dimers via its LexA-like G124 residue and UmuD-like N100 residue (UmuD is a component of an error-prone polymerase). However, N100 is not needed if the C termini are free. …

A Brief History Of Environmental Policy Through Literature, Nathan Walden, Brady Lawson, Adam Abdel-Rahman, Mathew Delancey, Douglas Mock

2023 Celebration of Student Scholarship - Poster Presentations

Environmental policy is a relative newcomer on the scene of federal regulation, with cries for a unified federal environmental response ignited by the publication of Silent Spring, by Rachel Carson in 1962 which exposed the new field of environmental science and its effects to the American public. However, the tradition of literature driving public awareness and federal policymaking does not stop at its genesis with many seminal works such as Collapse, by Jared Diamond, The Diversity of Life, by Edward O. Wilson, and Love Canal, by Richard Newman, continuing to do the same. These books have continued to …

Fundamental Or Negligible?: Kentucky P-12 Teacher Websites, Maddie Stamper, Lesia Lennix Apr 2023

Fundamental Or Negligible?: Kentucky P-12 Teacher Websites, Maddie Stamper, Lesia Lennix

2023 Celebration of Student Scholarship - Poster Presentations

How does a P-12 classroom teacher communicate at large with their students or their parents? There are countless ways for teachers to communicate with others. We determined that the more effective route in teacher communication would be an access-key-based Google Classroom, or an open-access teacher website linked directly to their respective school's website. An available, published teacher website allows anyone with internet access to view teacher-proffered information. This information could include their name, email, phone number, short biography, picture, or Google Classroom link. We found that the most effective information to include on a teacher's website would be their name, …

Causality: Hypergraphs, Matter Of Degree, Foundations Of Cosmology, Cliff Joslyn, Andres Ortiz-Muñoz, Edgar Daniel Rodriguez Velasquez, Olga Kosheleva, Vladik Kreinovich Apr 2023

Causality: Hypergraphs, Matter Of Degree, Foundations Of Cosmology, Cliff Joslyn, Andres Ortiz-Muñoz, Edgar Daniel Rodriguez Velasquez, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

The notion of causality is very important in many applications areas. Because of this importance, there are several formalizations of this notion in physics and in AI. Most of these definitions describe causality as a crisp ("yes"-"no") relation between two events or two processes -- cause and effect. However, such descriptions do not fully capture the intuitive idea of causality: first, often, several conditions are needed to be present for an effect to occur, and, second, the effect is often a matter of degree. In this paper, we show how to modify the current description of causality so as to …

Foundations Of Neural Networks Explain The Empirical Success Of The "Surrogate" Approach To Ordinal Regression -- And Recommend What Next, Salvador Robles, Martine Ceberio, Vladik Kreinovich Apr 2023

Foundations Of Neural Networks Explain The Empirical Success Of The "Surrogate" Approach To Ordinal Regression -- And Recommend What Next, Salvador Robles, Martine Ceberio, Vladik Kreinovich

Departmental Technical Reports (CS)

Recently, a new efficient semi-heuristic statistical method -- called Surrogate Approach -- has been proposed for dealing with regression problems. How can we explain this empirical success? And since this method is only an approximation to reality, what can we recommend if there is a need for a more accurate approximation? In this paper, we show that this empirical success can be explained by the same arguments that explain the empirical success of neural networks -- and these arguments can also provide us with possible more general techniques (that will hopefully lead to more accurate approximation to real-life phenomena).

Towards Decision Making Under Interval Uncertainty, Juan A. Lopez, Vladik Kreinovich Apr 2023

Towards Decision Making Under Interval Uncertainty, Juan A. Lopez, Vladik Kreinovich

Departmental Technical Reports (CS)

In many real-life situations, we need to make a decision. In many cases, we know the optimal decision in situations when we know the exact value of the corresponding quantity x. However, often, we do not know the exact value of this quantity, we only know the bounds on the value x -- i.e., we know the interval containing $x$. In this case, we need to select a decision corresponding to some value from this interval. The selected value will, in general, be different from the actual (unknown) value of this quantity. As a result, the quality of our decision …

Low-Probability High-Impact Events Are Even More Important Than It Is Usually Assumed, Aaron Velasco, Olga Kosheleva, Vladik Kreinovich Apr 2023

Low-Probability High-Impact Events Are Even More Important Than It Is Usually Assumed, Aaron Velasco, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

A large proportion of undesirable events like earthquakes, floods, tornados occur in zones where these events are frequent. However, a significant number of such events occur in other zones, where such events are rare. For example, while most major earthquakes occur in a vicinity of major faults, i.e., on the border between two tectonic plates, some strong earthquakes also occur inside plates. We want to mitigate all undesirable events, but our resources are limited. So, to allocate these resources, we need to decide which ones are more important. For this decision, a natural idea is to use the product of …

What Do Goedel's Theorem And Arrow's Theorem Have In Common: A Possible Answer To Arrow's Question, Miroslav Svitek, Olga Kosheleva, Vladik Kreinovich Apr 2023

What Do Goedel's Theorem And Arrow's Theorem Have In Common: A Possible Answer To Arrow's Question, Miroslav Svitek, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Kenneth Arrow, the renowned author of the Impossibility Theorem that explains the difficulty of group decision making, noticed that there is some commonsense similarity between his result and Goedel's theorem about incompleteness of axiomatic systems. Arrow asked if it is possible to describe this similarity in more precise terms. In this paper, we make the first step towards this description. We show that in both cases, the impossibility result disappears if we take into account probabilities. Namely, we take into account that we can consider probabilistic situations, that we can make probabilistic conclusions, and that we can make probabilistic decisions …

Using Transition State Theory To Understand The Kinetics For The Gas-Phase Synthesis Of Ammonia, Chloe Boyd, Stephen Case, Abigail Seputro Apr 2023

Using Transition State Theory To Understand The Kinetics For The Gas-Phase Synthesis Of Ammonia, Chloe Boyd, Stephen Case, Abigail Seputro

Research and Creativity Symposium

To identify the rate-determining step and the most stable transition state for the Haber-Bosch synthesis of gas-phase ammonia, electronic structure calculations for the reactants (N2, H2, NNH2, H2NNH2, HNNH3), intermediates, and transition states were found using the program GAMESS and the basis sets 6-31G*, 6-311G**, and STO-3G (1). The basis set 6-31G* revealed N2(g) + 3H2(g) ⇌ TS1 ⇌ NNH2(g)+ 2H2(g) as the rate-determining step because it had the smallest equilibrium constant (Keq) of 4.2085*10-36. The reaction coordinate diagram showed the most stable transition state was TS4 from the step HNNH3(g) + H2(g) ⇌ TS4 ⇌ 2NH3(g), which had the …

Extending The Radius Of Convergence Of The Drinfeld Module Logarithm, Ethan Clapp Apr 2023

Extending The Radius Of Convergence Of The Drinfeld Module Logarithm, Ethan Clapp

Mathematics Senior Capstone Papers

Drinfeld modules are, in essence, a way to create a function field analogue to complex multiplication. With these modules, we can define a logarithm function analogous to the natural logarithm by virtue of a power series. Similarly to how we extend the radius of convergence of the natural logarithm with complex numbers, we can also extend the radius of convergence for these Drinfeld module logarithms. While there are proofs for extending the radius of convergence of the Carlitz module, the simplest form of Drinfeld module, there is no proof for a generalized Drinfeld. In this paper, a method of extending …
