Dodge, Duck, Dip, Dive & Dependence: Using Dodgeball to Explore Frequency Dependent Selection
(2016-09)The term frequency dependence describes scenarios in which the likelihood of an event occurring is strongly tied to how common a particular trait is. Understanding frequency dependence is key to understanding ... -
Uptake of and Resistance to the Antibiotic Berberine by Individual Dormant, Germinating and Outgrowing Spores as Monitored by Laser Tweezers Raman Spectroscopy
(2015-12)Article Authors Metrics Comments Related Content Abstract Introduction Materials and Methods Results Discussion Supporting Information Acknowledgments Author Contributions References Reader Comments (0) Media ... -
Label-free classification of cultured cells through diffraction imaging
(2011-05)Automated classification of biological cells according to their 3D morphology is highly desired in a flow cytometer setting. We have investigated this possibility experimentally and numerically using a diffraction imaging ... -
Memory of Germinant Stimuli in Bacterial Spores
(2015-11)Bacterial spores, despite being metabolically dormant, possess the remarkable capacity to detect nutrients and other molecules in their environment through a biochemical sensory apparatus that can trigger spore germination, ... -
In Vivo Blood Glucose Quantification Using Raman Spectroscopy
(2012)We here propose a novel Raman spectroscopy method that permits the noninvasive measurement of blood glucose concentration. To reduce the effects of the strong background signals produced by surrounding tissue and to obtain ... -
Kinetics of Germination of Individual Spores of as Measured by Raman Spectroscopy and Differential Interference Contrast Microscopy
(2013)Geobacillus stearothermophilus is a gram-positive, thermophilic bacterium, spores of which are very heat resistant. Raman spectroscopy and differential interference contrast microscopy were used to monitor the kinetics of ... -
Improving Low-Relief Coastal LiDAR DEMs with Hydro-Conditioning of Fine-Scale and Artificial Drainages
(2015-11-23)Improvements in Light Detection and Ranging (LiDAR) technology and spatial analysis of high-resolution digital elevation models (DEMs) have advanced the accuracy and diversity of applications for coastal hazards and natural ... -
VIABILITY OF CERIUM OXIDE NANOPARTICLES AS A RADIOPROTECTOR AGAINST PROTON RADIATION FOR NON-MALIGNANT CELLS
(East Carolina University, 2015)Radiation therapy is a prevalent cancer treatment therapy. The goal is to kill all tumor cells while minimizing damage to healthy cells and new methods that can accomplish this goal are continually being investigated. ... -
Eigenvalues for Sums of Hermitian Matrices
(East Carolina University, 2015)In this thesis we explore how the eigenvalues of nxn Hermitian matrices A,B relate to the eigenvalues of their sum C=A+B. We mainly focus on inequalities bounding sums of r eigenvalues for C by sums of r eigenvalues for A ... -
Markov Chains, Random Walks, and Card Shuffling
(East Carolina University, 2016)A common question in the study of random processes pertains to card shuffling. Whether or not a deck of cards is random can have huge implications on any game being played with those particular cards. This thesis explores ... -
Elucidating Gene Function with the use of Genome Wide Association Study (GWAS)
(East Carolina University, 2015)DNA replication and cell proliferation are intensely studied subjects. There have been countless experiments and hours put into better understanding how DNA is replicated and compacted, and how cells are able to proliferate ... -
INSIGHTS INTO THE HABITAT AND BREEDING BIOLOGY OF THE FEDERALLY ENDANGERED HERBACEOUS PLANT, THALICTRUM COOLEYI, AHLES
(East Carolina University, 2015)Thalictrum cooleyi Ahles (Cooley's meadowrue, Ranunculaceae) is a dioecious species, endemic to fire-dependent, wet pine savannas of the southeastern US. T. cooleyi was listed as federally endangered in 1989; knowledge ... -
Hydrogeomorphology and Horizontal Movement of Juncus roemerianus
(East Carolina University, 2015)Juncus roemerianus, black needlerush, is common in high marshes and occasionally in low marshes along the Mid-Atlantic and southern USA. Previous work found that J. roemerianus patches remained relatively stable in the ... -
Targeting aberrant signaling in the EGFR1/HER2/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway : Novel therapeutic interventions in breast cancer
(East Carolina University, 2015)Breast cancer is attributed to being the second most deadly cancer in American women. Approximately 1 in 8 women will be diagnosed with breast cancer during her lifetime, and prognosis is dependent upon the genetic make-up ... -
Analysis of scn5Laa and scn5Lab Gene Function in Danio rerio (Zebrafish) Heart Development through TALENs/CRISPR-CAS9-mediated Gene Knockout
(East Carolina University, 2015)Research in our laboratory is focused on understanding the molecular developmental genetic effects of crude oil exposure on vertebrate embryogenesis. Our research has demonstrated that exposure of zebrafish embryos to ... -
Generational Differences and Predictors of Variance in Marital Attitudes among Men
(East Carolina University, 2015)The rise of cohabitation, premarital sex, childbearing outside of marriage, and a higher average age for first marriage allude to changes in the institution of marriage, and perhaps a changing society. According to a 2010 ... -
A Bioethical Consideration of End of Life Care
(2015)This project is a thesis on the bioethical considerations involved in moving a terminally ill patient to End of Life Care, commonly known as comfort care. Literature reviews have been carefully integrated, as well as a ... -
THE TRAINING AND DECISIONS OF KING LEONIDAS: THE INFLUENCES BEHIND THE LEADER
(2015-05)The Battle of Thermopylae produced unique circumstances that required King Leonidas of Sparta to make a series of controversial decisions. Scholars debate what purpose it served for him to cling to his position when it had ... -
