A Radar Countermeasure Modeling Method Incorporating Cognitive Bias, Rui Wang, Xiangyang Li, Dong Wang, Hongguang Ma, Zhili Zhang

Journal of System Simulation

Abstract: Cognitive bias, stemming from electronic measurement error and variability in human perception, exists in cognitive electronic warfare and affects the outcomes of conflicts. In this paper, the dynamic game approach is employed to develop a model for cognitive bias induced by incomplete information and measurement errors in cognitive radar countermeasures. The payoffs for both parties are calculated using the radar's anti-jamming strategy matrix A and the jammer's jamming strategy matrix B. With perfect Bayesian equilibrium, a dynamic radar countermeasure model is established, and the impact of cognitive bias is analyzed. Drawing inspiration from the cognitive bias analysis method used …

The Roles Of Cup1, Ssu1, And Mitochondrial Dna In Copper Tolerance In Wild Yeasts, Madeleine Panek

Undergraduate Honors Theses

Understanding the genetic basis of complex traits remains a central challenge in biology. In Saccharomyces cerevisiae, copper resistance is a multifactorial trait shaped by both genetic and environmental influences, yet its underlying mechanisms are not fully understood. The genes CUP1 and SSU1 are known to influence copper resistance, though how these genes interact with each other and with mitochondrial DNA (mtDNA) variation in wild yeast populations is unknown. I hypothesized that the genes CUP1 and SSU1 and variation in mtDNAs contribute to copper resistance in wild yeasts independently and through genetic interactions. To test this, I measured copper resistance …

Scoping Review Of Algorithms For Electronic Fetal Monitoring, Katherine Sabatier, Kate Fouquier Cnm, Phd, Facnm

Doctor of Nursing Practice Projects

Purpose/Background

The purpose of this scoping review is to review the use of an algorithm in evaluating continuous external fetal heart rate (FHR) monitoring in labor as opposed to clinician judgment for improved fetal outcomes, including earlier recognition of abnormal tracings (Clark et al., 2017). FHR monitoring was created to evaluate for fetal hypoxia in labor and has become standard practice (Gyllencreutz et al., 2018). One of the goals of the use of cardiotocography is to decrease hypoxia-induced fetal metabolic acidemia and neurologic injury. There are multiple options for individual or computer-based algorithms in evaluating FHR to reduce fetal acidemia …

Lipid Dysregulation In Sebaceous Gland Disorders And The Impact Of Sphingolipid Metabolism On Acne Pathogenesis, Kaitlyn Miner, Ryan Murphy, Samantha Steiss, Mckenzie Burian, Hannah Welp, Alexandra Loperfito, Ashley O'Malley, Radhika Misra, Kelly Frasier

Student Publications

Lipid dysregulation within sebaceous glands is a critical factor underlying the pathogenesis of sebaceous gland disorders, particularly acne vulgaris. Sebaceous glands synthesize and secrete a complex mixture of lipids, including triglycerides, wax esters, free fatty acids, and sphingolipids, which contribute to skin barrier function and microbial homeostasis. Dysregulated lipid production, characterized by increased sebum secretion and altered lipid composition, has been implicated in promoting Cutibacterium acnes proliferation, hyperkeratinization, and inflammation, key processes in acne pathogenesis. Recent research highlights the pivotal role of sphingolipid metabolism, particularly ceramides, in modulating sebaceous gland activity and skin inflammation. Ceramide deficiencies in acne-prone skin contribute …

Primary Care Telehealth In A Dynamic Healthcare Environment From Digital Divide To Healthcare Outcomes

Faculty, Staff and Student Publications

With expanded telehealth availability in primary care, its impact on quality of care and associated costs remains debated. Analyzing 199,829 Medicare beneficiaries in Mississippi (2019-2021), we found telehealth utilization associated with significant sociodemographic disparities, reduced inpatient admissions, and lower 30-day readmissions. By accounting for primary care utilization, our findings suggest that the higher absolute costs observed among telehealth users may reflect underlying healthcare needs rather than telehealth utilization.

‘Somebody Did Something’: Pell-Eligible Community College Student Perceptions Of Financial Aid, Sarah V. Diehl, Mia Ocean

Journal of Student Financial Aid

With tuition increasing at a faster rate than inflation, many college students depend on financial aid to access education. The largest form of federal aid is the Pell Grant, which subsidizes over 30 billion a year worth of tuition for eligible students. While the ED is not required by Congress to measure success outcomes for Pell recipients, quantitative research has produced mixed results. Researchers have explored what causes Pell-eligible students to fail or persist, but the reasons can be varied and intersectional. However, little research exists on the student perspectives of financial aid, apart from their financial literacy or their …
