Title: ELUCIDATING FUNCTIONAL MECHANISMS IN PROTEINS USING THE DISTANCE CONSTRAINT MODEL
Author: Singer, Christopher
Date Created: 2019
Subjects--Topical: Bioinformatics, Biophysics, Physics
Description: Protein thermodynamics has been shown to be insightful and illuminating to the functional mechanisms behind biological function. By characterizing proteins and protein families according to their enthalpy and entropy we can make inferences to the ...

Title: Elucidating Dynamic Mechanisms for Extended Spectrum Antibiotic Resistance in Class A Beta-Lactamase through Machine Learning on Molecular Dynamics Simulations
Author: Avery, Christopher
Date Created: 2019
Subjects--Topical: Biophysics, Physics
Description: Beta-lactamase is a protein which is produced in bacteria and is a primary cause of antibiotic resistance to Beta Lactam antibiotics. Beta Lactams are among the most common types of antibiotics (including penicillin) and thus understanding the res...

Title: High throughput non-parametric probability density estimation via novel multithreaded stitching method
Author: Merino, Zach
Date Created: 2019
Subjects--Topical: Mathematics, Statistics, Physics
Description: A method of univariant probability density function (pdf) estimation is developed for big data applications. The method employs the use of a non-parametric maximum entropy estimator (NMEM) for a data driven multithreaded probability density estima...

Title: Implementation of Focusing Light through Highly Scattering Media via Sequential Algorithm Based Wavefront Shaping
Author: Williams, Desmond
Date Created: 2019
Subjects--Topical: Physics
Description: Propagation of light in communications, medicine, and science is hindered by the phenomenon of optical scattering. Methods to overcome this physical limitation have and continue to be researched. This work attempts to implement the method of wavef...

Title: PREPARATION AND VISUALIZATION OF INDIVIDUAL ACTIN FILAMENTS USING ATOMIC FORCE MICROSCOPY FOR THE STUDY OF ACTIN/DNA HYDROGEL COMPLEXES
Author: Kennedy, Joshua
Date Created: 2019
Subjects--Topical: Physics, Biophysics, Biomedical engineering
Description: A protocol of sample preparation for the visualization of single actin filaments at the nanoscale using atomic force microscopy for use in studies of engineered actin/DNA conjugated hydrogel complexes was developed. Hydrogels are cross-linked netw...

Title: RED FLUORESCENCE IN BOVINE SERUM ALBUMIN – GOLD COMPLEXES
Author: Dixon, Jacob
Date Created: 2019
Subjects--Topical: Optics, Physics
Description: Bovine serum albumin (BSA)-gold (Au) complexes have been studied in great detail due to their unique red fluorescent (λem = 640 nm) properties, since being initially described by Xie et al. (J. Am. Chem. Soc. 2009, 131, 888-889) as a Au25 nanoclus...

Title: SOLUTION OF A 1-D INVERSE PROBLEM BY THE CONVEXIFICATION METHOD
Author: Abney, Ray
Date Created: 2019
Subjects--Topical: Mathematics, Physics
Description: In this thesis, we demonstrate a method outlined by Dr. Mikhail Klibanov for solving a 1-D coefficient inverse problem by the convexification method. Our inverse problem in question concerns finding buried bombs, where the dielectric constants of ...

Title: Scintillation properties of a partially coherent vector beam with vortex phase in turbulent atmosphere
Author: Gbur, Greg, Yu, Jiayi, Cai, Yangjian, Huang, Yan
Date Created: 2019
Subjects--Topical: Physics, Optics
Description: We undertake a computational and experimental study of an advanced class of structured beams, partially coherent radially polarized vortex (PCRPV) beams, on propagation through atmospheric turbulence. A computational propagation model is establish...

Title: Spiral spectrum of a Laguerre-Gaussian beam propagating in anisotropic non-Kolmogorov turbulent atmosphere along horizontal path
Author: Gbur, Greg, Zeng, Jun, Liu, Xianlong, Cai, Yangjian
Date Created: 2019
Subjects--Topical: Physics, Optics
Description: Close to the ground, it is generally known that atmospheric turbulence exhibits strong anisotropy, which affects the performance of applications such as free-space optical (FSO) communication. In this paper, we establish a theoretical model for ca...
