We also tested with six different types of antibiotics, and as a result, only three of them …

Ancestral Sequence Reconstruction On Antibiotic-Resistance Bacteria, Jeyun Park

SACAD: Scholarly Activities

The spread of antibiotic-resistant bacteria poses a global health threat, and it is predominantly driven by enzymes that neutralize antibiotics or alter their drug targets. This study uses Ancestral Sequence Reconstruction (ASR) to explore the evolutionary history of a key bacterial enzyme that plays a role in antibiotic resistance. Protein sequences were aligned, and a phylogenetic tree constructed utilizing MEGA 11. Ancestral sequences are predicted to identify the conserved regions that are essential for enzyme function. Understanding these conserved locations provides insights into potential drug targets for developing new drugs against resistant strains of bacteria.

Optimizing Transcription Efficiency Through Mutations In The T7 Rna Polymerase, Claire N. Novak

Honors Program: Senior Projects (Public)

The production of RNA is vital for many commercial and research purposes, with one of the more notable reasons being vaccine production. The RNA polymerase, derived from T7 bacteriophage, is commonly used for RNA production due to its ability to produce full-length RNA transcripts. However, researchers have faced limitations in optimizing this polymerase. For example, the polymerase generates heterogeneous RNA products that require additional purification steps during RNA production. Here, we selected three amino acid point substitutions based on a recent publication from Moderna that showed increased RNA purity compared to the wild type T7 RNA polymerase sequence. We created …

The Tate Resolution Over A Complete Intersection Ring, Kolton O'Neal

Honors Program: Senior Projects (Public)

Given a Noetherian commutative ring R and an ideal I ⊆ R, Tate provided a construction in [5] to produce a DG R-algebra that is also a free resolution for R/I. In this work, we review free resolutions and DG algebras, describe Tate’s construction, and present a proof of a result from Tate’s paper about his construction when a regular sequence is involved. Specifically, this result is that it only takes two steps of Tate’s construction to resolve a characteristic 0 field k over k[[x1, . . . , xn]]/(f1, . . . , fc), where f1, . . . …

Integrated Geophysical Modeling Of Newly Identified Pseudofaults Within Southern Cascadia Subduction Zone, Morgan R. Madsen

Honors Program: Senior Projects (Public)

The Cascadia Subduction Zone, located off the western coast of North America, has a long history of seismic activity, causing various geohazards such as megathrust earthquakes and tsunamis for the coastal population (Goldfinger et al., 2000; Tréhu et al., 2022). It is necessary to identify areas of greater risk, as seismic hazards will continue to affect the area due to ongoing subduction of the oceanic Juan de Fuca plate beneath the North American continent. Heavily fractured, weakened zones of oceanic crust, known as propagator wakes and pseudofaults, have been shown to correlate with greater seismicity (Ashraf and Filina, 2023a). Propagator …

School of Public Health Faculty Publications

Global hepatic DNA methylation change has been linked to human patients with metabolic dysfunction-associated steatotic liver disease (MASLD). DNA demethylation is regulated by the TET family proteins, whose enzymatic activities require 2-oxoglutarate (2-OG) and iron that both are elevated in human MASLD patients. We aimed to investigate liver TET1 in MASLD progression. Depleting TET1 using two different strategies substantially alleviated MASLD progression. Knockout (KO) of TET1 slightly improved diet induced obesity and glucose homeostasis. Intriguingly, hepatic cholesterols, triglycerides, and CD36 were significantly decreased upon TET1 depletion. Consistently, liver specific TET1 KO led to improvement of MASLD progression. Mechanistically, TET1 promoted …

Bi-Level Energy Dispatch Optimisation For Peak Load Shaving In Microgrids With Battery Storage, Mohd Fakhizan Romlie, Abid Ali, Gm Shafiullah

Platform: A Journal of Engineering (PAJE)

Peak load periods in electrical networks result in significant power losses, straining generation capacity, and increasing operational costs. Strategically optimising electricity supply from battery storage-based distributed generation (DG) during these peak times can mitigate these losses and enhance grid efficiency through peak load shaving (PLS). However, electrical loads vary throughout the day and night. Thus, identifying peak and off-peak loads would be the most challenging task to complete before scheduling operations for batteries. This study presents a bi-level energy optimisation framework to identify the peak and off-peak loads and plan the energy dispatching operations for battery storage. The bi-level energy …

Adaptive Control System Of Nonlinear Dynamic Object On The Basis Of Neuro-Fuzzy Networks, Isomiddin Xakimovich Siddikov, Dilnoza Maxamadjanovna Umurzakova

Technical science and innovation

The presented paper is devoted to the development of an adaptive control system for a nonlinear dynamic object using neuro-fuzzy networks. The authors note that in real conditions dynamic objects function under conditions of uncertainty, which are characterised by complex and poorly understood relationships between technological variables, the presence of perturbing and random disturbances, as well as nonlinear elements. This makes it difficult to apply traditional linear adaptive control algorithms. The use of self-organising adaptive control is proposed, in which the mathematical model of the controlled system is formed by operational identification during system operation. It is shown that linear …

Designing modern rehabilitation exoskeleton systems requires a comprehensive study of human-machine interactions. In this process, creating kinematic and dynamic mathematical models of the system is extremely important. In this paper, we develop mathematical models that describe rehabilitation exoskeleton systems' kinematic and dynamic properties. Based on the Denavit-Hartenberg method we construct kinematic model of the exoskeleton system. The method gave us to determine the coordinate system for each joint. Furthermore, we also study the motion range of joints of the exoskeleton. Modeling the dynamic properties of the system performed with the second-order Lagrange equation. The exoskeleton construction consisting of knee, thigh, …

Unavoidable Immersions And Topological Minors Of K-Edge-Connected Graphs, Brittian Qualls

LSU Doctoral Dissertations

In this work, we present results concerning the unavoidable structures in large and infinite k-edge-connected graphs. These results are inspired by the classical result of Ramsey, who proved that for every positive integer r, every sufficiently large graph contains as an induced subgraph either K_r or $\overline{K_r}$. We consider different graph containment relations, focusing primarily on the immersion relation. In the case of finite graphs, we provide the unavoidable immersions of 4-edge-connected graphs and prove that linear edge-connectivity suffices to immerse the graph C_t,r.

This dissertation also considers infinite graphs. We present the …

Optical Spring Tracking For Enhancing Quantum-Limited Interferometers, Scott M. Aronson

LSU Doctoral Dissertations

Gravitational waves were first predicted by Albert Einstein in 1916. Calculations in the 1970s by Rainer Weiss showed an interferometer of sufficient size could realistically detect gravitational waves, which led to a grant by the National Science Foundation (NSF). With steady progress and over decades of funding by the NSF, the construction of two full scale 4km interferometers was approved and began construction in 1994. This project, coined LIGO the Laser Interferometer Gravitational-wave Observatory, came to be a worldwide collaboration of scientists dedicated to the discovery and study of gravitational waves. In 2015, both LIGO detectors detected a coincident inspiral …

Explaining "U-Shaped" Distributions Of Population Substance Use With A Simple Computational Approach, Jacob T. Borodovsky

Dartmouth Scholarship

Background: “U-shaped” distributions of past 30-day substance use frequencies are pervasive, yet no established model explains this phenomenon. Using probability functions to describe these distributions yields unintuitive, atheoretical results. This study introduces a simple computational model of individual-level, longitudinal substance use patterns to understand how cross-sectional U-shaped distributions emerge in populations. Model: Each independent computational object transitions between two states: not using a substance (“N”), or using a substance (“U”). The model has two key components: (1) each object has a unique risk factor probability governing the transition from N to U, and a unique protective factor probability governing the …

Poetic Philosophy And The Moralization Of Social Networks, Finn Janning

Emancipations: A Journal of Critical Social Analysis

In this paper, I aim to explore the question, “What distinguishes philosophy in its original sense? ” My intent is not to provide a historical overview of philosophy, but to concentrate on what makes philosophy a liberating practice. I argue that this practice is rooted in its poetic and affirmative way of organizing life. To emphasize this idea, I contrast it with the presumed organization found in social media and networks. While social media and networks encourages commitment by simplifying complexity, they also restrict users' freedom, responsibility, and ability to make meaningful decisions. To support these claims, I examine the …
