Lèvy noise induced steady states
(East Carolina University, 2022-06-08)Systems far from equilibrium organize themselves to accommodate energy throughput. It is also in these nonequilibrium systems where noise has often been found to follow alpha-stable distributions, commonly called Lévy ... -

Localization of soniferous fish using a sparse hydrophone array and conventional steered response power method
(East Carolina University, 2019-12-10)A sparse seven-channel hydrophone array was deployed in intertidal marsh creeks located within the North-Inlet-Winyah-Bay Nature Reserve at Baruch Marine Field Laboratory in Hobcaw Barony, Georgetown, South Carolina, USA. ... -
Magnetic Control of NanoEL via Magneto-Mechanical Actuation: A proof of Concept for a Potential Nanotherapeutic Approach
(East Carolina University, 2023-05-03)Cancer treatment is one of the major health problems that burdens society. According to the latest publication of the American Cancer Society, the cancer mortality rate has reached 32% in 2022 in the US. To address these ... -
Mathematical Modeling of Oxygen Transport, Cell Killing and Cell Decision Making in Photodynamic Therapy of Cancer
(East Carolina University, 2012)In this study we present a model of in vitro cell killing through type II Photodynamic Therapy (PDT) for simulation of the molecular interactions leading to cell death in time domain in the presence of oxygen transport ... -
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, ... -

Methods and systems for optically characterizing a turbid material using a structured incident beam
(2010-04-08)Methods and systems for optically characterizing a turbid sample are provided. A structured light beam is impinged on the sample. The sample includes an embedded region. A reflected light image of the structured light beam ... -
MODIFICATION OF CELL SURVIVAL RATES BY CERIUM OXIDE NANOPARTICLES FOR EXPOSURE TO PROTON RADIATION
(East Carolina University, 2017-05-03)Radiation therapy is a well-established and widely used treatment for a variety of malignancies in the human body. Current radiotherapy methods most frequently use x-rays to deliver a lethal dose to tumors with sufficient ... -
Multi-wavelength beam splitting systems for simultaneous imaging of a distant object in two or more spectral channels using a single camera
(2016-09-29)An optical imaging system and related methods are provided that acquire images of an object at a distance in different spectral regions using only one camera. The systems and methods are adaptable to applications where ... -
Mutation of tandem repeats in fibrin's alpha-C region
(East Carolina University, 2018-01-19)Cardiovascular problems such as myocardial infarctions and emboli are the number one killers in the United States. These health concerns arise from blood clotting unnecessarily in the veins or arteries. Studies have shown ... -
A new assessment model for tumor heterogeneity analysis with [18]F-FDG PET images
(2016-01)It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]F-FDG PET image data. The existing models employ multiple parameters for feature extraction which makes it ... -
Optical and dielectric properties of metallic calcium, modeled generalized oscillator strength function of calcium, interaction cross sections of electrons, protons, and alpha particles with calcium
(East Carolina University, 2013)An analysis of the optical and the dielectric properties of calcium, determined from the literature, was performed. The optical functions of calcium were used for a calculation of the energy loss function of calcium. The ... -
Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
(East Carolina University, 2016-05-03)Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ... -
Optimizing graphene oxide reduction via laser irradiation
(East Carolina University, 2017-01-04)The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. ...
