Q-Learning Enhanced Memetic Algorithm For Robust Scheduling Of Space Launch Missions, Rui Lin, Xiaolu Liu, Yonghao Du, Mingyang Geng, Zhenshun Shi

Journal of System Simulation

Abstract: A robust optimization mathematical model and an enhanced memetic algorithm (MA) for space launch mission scheduling are proposed to address the practical challenges in space launch mission scheduling under the influence of multiple uncertainties such as equipment failure, process rework due to quality issues, and technological changes. A robust optimization scheduling model for space launch missions is built by integrating the makespan under the worst-case scenario, the average maximum makespan, and the average deviation of process start times. A Q-learning enhanced memetic algorithm (QMA) is proposed, which can dynamically select parent solutions based on the population state. Simulation experiments …

Investigating The Prevalence Of Human Papilloma Virus In A College-Aged Sample Group And Its Link To Sexual Behaviors And Attitudes, Gabriela Lewczyk, Eva Pollak, Phoebe Stryker, Samantha Hickey, Emily Moyer, Katelyn Ambrose, Alexander Knight, Rahjai Thomas, Adriana Burk, Paul E. Richardson

Journal of the South Carolina Academy of Science

Human Papilloma Virus (HPV) is the most common sexually transmitted infection (STI) in the United States, infecting up to 75% of sexually active individuals, with a prevalence rising significantly around age nineteen for oral and genital infections. Because the virus infects epithelial cells and is transmitted primarily through skin-to-skin contact, it is found mainly in the cervix, oral cavity, and on/within ones’ skin. While most of the 200+ HPV subtypes are benign and tend to self-clear within six months to two years, twelve of these strains are classified as high-risk oncogenic strains that drive malignant progression. Furthermore, HPV is linked …

The Structure And Regulatory Mechanism Of The Emrb Rna Motif In Lactobacillus Acidophilus, Isabella J. Mezzenga, Brian M. Lee

Journal of the South Carolina Academy of Science

Major facilitator superfamily (MFS) transporters aid bacteria in expelling toxic compounds such as antibiotics, bile acids, and other substances. Previous bioinformatic studies identified the emrB motif as a potential regulatory RNA element. In Lactobacillus, this RNA motif is generally found in the intergenic region upstream of an MFS transporter gene with homology to the emrB gene from Escherichia coli. Secondary structure predictions of the intergenic region were used to define the structural features of this RNA motif. The emrB motif comprises two hairpins, though inclusion of neighboring regions is predicted to stabilize alternative secondary structures. A potential rho independent terminator …

Exploring The Dynamics Of Tilted, Truncated Accretion Disks, José L. Montés, Chris Fragile, Deepika Bollimpalli, Matthew Liska

Journal of the South Carolina Academy of Science

Tilted accretion disks are theoretically not uncommon in stellar mass black hole systems. The dynamics of tilted disks display interesting physical behaviors that could explain certain observational phenomena such as quasi-periodic oscillations. We present results of recent numerical simulations of tilted, truncated accretion disks around rotating black holes. Our simulations model systems composed of a thick inner torus surrounded by a thin outer disk and were run with the goal of investigating the behaviors of the torus because of the exchange of angular momentum between it and the outer disk. Multiple simulations produced surprising results, such as the potential tearing …

From Classification To Segmentation: Evaluating Machine Learning Defect Localization And Inspector Performance In Manufacturing, Gavin Smithson, Dakota Fulp, William M. Jones, Sharmistha Chakrabarti

Journal of the South Carolina Academy of Science

High-volume manufacturing at Los Alamos National Laboratory requires rigorous quality assurance; however, sustained manual inspection can be inconsistent, costly, and fatiguing. This paper presents the model-evaluation component of a larger human-in-the-loop artificial intelligence project for manufacturing anomaly detection. MicroSentryAI uses pretrained models to identify potential anomaly regions, while AnnoMate provides accessible tools for annotating, validating, and comparing those regions. The study emphasizes the distinction between classification, which determines whether a sample is anomalous, and segmentation, which identifies the location of an anomaly. Using Intersection over Union (IoU), precision, recall, and Euclidean distance between centroids, experiments with simulated mask errors demonstrated …

A Philosophical Introduction To Elements And Relations: Aspects Of A Scientific Metaphysics, Martin Zwick

Complex Systems Faculty Publications and Presentations

My book, Elements and Relations*, amplifies Bunge’s characterization of the systems project as the construction an “exact and scientific metaphysics” (ESM) different from and broader than the reductionist and physicalist ontology of conventional science. This paper discusses the scientific theories constituting this project and the central notion of “system” as a structure-function dyad, where “structure” is the system’s internal order and “function” is its participation in the external order of its environment. The paper also discusses the book’s proposal of ontology and ethics as a structure-function dyad for the systems field, an ontology of problems that exemplifies the ESM idea.

Promoting Safety In Alcohol Withdrawal Syndrome: A Proactive Nursing Process Framework, Julie Anne C. Comia, Elizabeth Card

HCA Healthcare Journal of Medicine

Background

Alcohol withdrawal syndrome (AWS) is a potentially life-threatening response to the abrupt cessation or reduction of heavy, prolonged alcohol use. Untreated, it can progress to delirium tremens (DT), a medical emergency historically associated with mortality as high as 40%. Agitation and hallucinations during withdrawal also pose safety risks to the health care team in addition to the patient. Because deterioration follows a predictable course, timely nursing recognition and intervention are central to protecting both the patient and the care team from avoidable harm. The evidence-based framework is intended as an educational tool to help nurses anticipate and avoid harm; …
