On The Hardness Of The Balanced Connected Subgraph Problem For Families Of Regular Graphs, Harsharaj Pathak Dec 2023

On The Hardness Of The Balanced Connected Subgraph Problem For Families Of Regular Graphs, Harsharaj Pathak

Theory & Applications of Graphs

The Balanced Connected Subgraph problem (BCS) was introduced by Bhore et al. In the BCS problem we are given a vertex-colored graph G = (V, E) where each vertex is colored “red” or “blue”. The goal is to find a maximum cardinality induced connected subgraph H of G such that H contains an equal number of red and blue vertices. This problem is known to be NP-hard for general graphs as well as many special classes of graphs. In this work we explore the time complexity of the BCS problem in case of regular graphs. We prove that the BCS …

The Vulnerabilities To The Rsa Algorithm And Future Alternative Algorithms To Improve Security, James Johnson Dec 2023

The Vulnerabilities To The Rsa Algorithm And Future Alternative Algorithms To Improve Security, James Johnson

Cybersecurity Undergraduate Research Showcase

The RSA encryption algorithm has secured many large systems, including bank systems, data encryption in emails, several online transactions, etc. Benefiting from the use of asymmetric cryptography and properties of number theory, RSA was widely regarded as one of most difficult algorithms to decrypt without a key, especially since by brute force, breaking the algorithm would take thousands of years. However, in recent times, research has shown that RSA is getting closer to being efficiently decrypted classically, using algebraic methods, (fully cracked through limited bits) in which elliptic-curve cryptography has been thought of as the alternative that is stronger than …

Laudato Si' And The Christian Ethic, Brandon Kriplean Dec 2023

Laudato Si' And The Christian Ethic, Brandon Kriplean

Venture: The University of Mississippi Undergraduate Research Journal

Christianity, specifically Catholicism, is an inherently anthropocentric religion, with humans having the most dignity of all mortal creatures due to their divine image. However, what does such a lofty view of humanity mean for the current environmental crises? Are Christianity and environmental stewardship mutually exclusive paradigms? Pope Francis has sought to maintain human dignity while at the same time encouraging the Church to recognize that the environment, as God’s creation, is not to be exploited. In other words, an anthropocentric perspective does not equal a disregard for other aspects of creation. His 2015 landmark encyclical, Laudato Si’, sought to highlight …

Hypothesis And Theory: Do Trees "Release The Tension" In Rainwater? Surface Tension Reduction In Throughfall And Stemflow From Urban Trees, Benjamin J. Noren, Nicholas R. Lewis, Kelly Cristina Tonello, Anna Ilek, John T. Van Stan Ii Dec 2023

Hypothesis And Theory: Do Trees "Release The Tension" In Rainwater? Surface Tension Reduction In Throughfall And Stemflow From Urban Trees, Benjamin J. Noren, Nicholas R. Lewis, Kelly Cristina Tonello, Anna Ilek, John T. Van Stan Ii

Biological, Geological, and Environmental Faculty Publications

Knowledge of the processes and impacts associated with the canopy's partitioning of rainfall into stemflow (water that drains to the base of tree stems) and throughfall (water that drips through gaps and from canopy surfaces) has expanded in recent years. However, the effect of canopy interactions on the fundamental physical properties of rainwater as it travels through the canopy to the soil, particularly surface tension, remains understudied. To discuss specific hypotheses within this context and their relevance to ecohydrological theory, the surface tension of rainwater samples was examined directly. Over a period of 9 months, open rainwater, throughfall and stemflow …

Analyzing The Efficacy Of Covid-19 Travel Bans: A Regression Analysis Approach, Mallory Kochanek

Honors Projects

Some might associate the term ‘public health’ with the pandemic that occurred in 2020. COVID-19 spread like most have never seen in their lifetime. It is useful to look at the effectiveness of the travel re- strictions in mitigating the spread of the global pandemic. Using linear regression and network regression, we obtain parameter estimates to determine the relation of predictors, such as network effect, percentage of urban population and GDP, on the COVID-19 incidence rate for the months January to April of 2020. Linear regression does not ac- count for the correlation structure of the data. Network regression, on …

Renormalized Stress-Energy Tensor For Scalar Fields In Hartle-Hawking, Boulware, And Unruh States In The Reissner-Nordström Spacetime, Julio Arrechea, Cormac Breen, Adrian Ottewill, Peter Taylor Dec 2023

Renormalized Stress-Energy Tensor For Scalar Fields In Hartle-Hawking, Boulware, And Unruh States In The Reissner-Nordström Spacetime, Julio Arrechea, Cormac Breen, Adrian Ottewill, Peter Taylor

Articles

In this paper, we consider a quantum scalar field propagating on the Reissner-Nordström black hole spacetime. We compute the renormalized stress-energy tensor for the field in the Hartle-Hawking, Boulware and Unruh states. When the field is in the Hartle-Hawking state, we renormalize using the recently developed “extended coordinate” prescription. This method, which relies on Euclidean techniques, is very fast and accurate. Once, we have renormalized in the Hartle-Hawking state, we compute the stress-energy tensor in the Boulware and Unruh states by leveraging the fact that the difference between stress-energy tensors in different quantum states is already finite. We consider a …

Prevalence, Faunal Composition, And Vertical Distribution Of Bioluminescence In The Pelagic Gulf Of Mexico: Fishes, Crustaceans, Cephalopods And Gelatinous Megaplankton, Devynne M. Brown Dec 2023

Prevalence, Faunal Composition, And Vertical Distribution Of Bioluminescence In The Pelagic Gulf Of Mexico: Fishes, Crustaceans, Cephalopods And Gelatinous Megaplankton, Devynne M. Brown

All HCAS Student Capstones, Theses, and Dissertations

Bioluminescence is the phenomenon of light emission by living organisms. It occurs through a chemical reaction within an organism and serves various purposes. The diversity of bioluminescent capabilities and occurrence in unrelated taxa suggest that bioluminescence has evolved independently numerous times amongst taxa thriving in certain environments. One such environment is the deep ocean, where little to no sunlight penetrates the water column, specifically in the mesopelagic (200-1000 m depth) and bathypelagic (> 1000 m) zones. The mesopelagic and bathypelagic zones have been extensively sampled and well documented in the Gulf of Mexico (GoM), one of the few places globally …

Evaluating The Effectiveness Of The Internal Transcribed Sequences (Its) As Dna Barcodes To Estimate Fungal Diversity, Jailisa Linares Dec 2023

Evaluating The Effectiveness Of The Internal Transcribed Sequences (Its) As Dna Barcodes To Estimate Fungal Diversity, Jailisa Linares

All HCAS Student Capstones, Theses, and Dissertations

Universal phylogenetic markers such as the nuclear ribosomal internal transcribed sequences (ITS), specifically ITS1 and ITS2, are routinely used to estimate fungal diversity in environmental samples. However, numerous studies report differences in the performance and efficacy of ITS1 and ITS2 in documenting fungal diversity. To better understand the implications of using ITS1 versus ITS2, a comprehensive representation of the diverse fungal taxa was necessary to conduct a meta-analysis of their use across multiple fungal taxa. In order to address this, a thorough literature review was conducted to compare and contrast the use of ITS1 and ITS2 as effective DNA barcodes. …

A Review On Possible Physical Meaning Of Elastic-Electromagnetic Mathematical Equivalences, Florentin Smarandache, Victor Christianto Dec 2023

A Review On Possible Physical Meaning Of Elastic-Electromagnetic Mathematical Equivalences, Florentin Smarandache, Victor Christianto

Branch Mathematics and Statistics Faculty and Staff Publications

It is known, despite special theory of relativity has been widely accepted, in our recent draft submitted to this journal it is shown that some experiments have been carried out suggesting superluminal wave propagation, which make Minkowski lightcone not valid anymore. Therefore, it seems worth to reconsider the connection between elastic wave and electromagnetic wave equations, as in their early development. In this paper we will start with Maxwell-Dirac isomorphism, then we will find its connection with elastic wave equations.

Academic Outcomes Of The Covid-19 Pandemic: Awareness And Action, Tanner B. Howe Dec 2023

Academic Outcomes Of The Covid-19 Pandemic: Awareness And Action, Tanner B. Howe

Masters Projects

Research has shown that the online learning implemented during the COVID-19-related school closures had impacts on academic outcomes among secondary students. As schools operate in proximity to this event, it is crucial to investigate and understand those academic outcomes. Research suggests that mathematics and reading/language courses displayed negative academic outcomes for the period of online learning. Through this investigation, stress was observed to have played a major role during this period for secondary students and may have also contributed to the academic outcomes observed. This project seeks to raise awareness of possible student educational needs by shining light on the …

Bitcoin And South African Stock Market Returns During Covid-19 Pandemic: A Test Of The Safe-Haven Hypothesis, Akaninyene U. Udom, Sopuru W. Nnamani

CBN Journal of Applied Statistics (JAS)

This paper tests the safe-haven property of Bitcoin for South African stocks using Full and Diagonal BEKK-GARCH models. The study uses the Johannesburg stock exchange Top40 index, and bitcoin returns data before COVID-19 (August 2018 to December 2019) and during COVID-19 (January 2020 to June 2021). The results show that bitcoin cannot be considered as safe-haven for stocks in South Africa since it is weakly correlated with stock and had a high volatility during the Pandemic. Therefore, the safe-haven hypothesis of bitcoin on South African stocks is not true for the period under study. The policy implication is that bitcoin …
