Cancer Cell Detection with Mask R-CNN

Creator:: Wong, Ryan
Abstract:: Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

Isolating Non-Blackbody Radiation Spectra from Low-Bandgap LEDs near Zero Bias

Creator:: Teo, YiPeng
Abstract:: The study of carrier transport in light-emitting diode (LED) has been researched extensively in the past. However, most studies were implementing voltages above the turn-on voltage of the LED. Research on LEDs well below the turn-on voltage threshold is comparatively scarce for good reasons. When the supply voltage is below...

Modeling the Fusion Reaction in an Inertial Electrostatic Confinement Reactor with the Particle-in-Cell Method

Creator:: van de Lindt, Jacob
Abstract:: Nuclear fusion has the potential to meet the energy needs of our civilization for centuries to come and does not produce harmful greenhouse gasses or produce long-lasting radioactive waste. A fusion reaction can be readily demonstrated in a confinement scheme known as inertial electrostatic confinement (IEC) fusion. In this work,...

Consistent Histories Formulation of the Double-Slit Experiment

Creator:: Bauml, Benjamin N.
Abstract:: The standard interpretation of quantum mechanics (known as the Copenhagen interpretation) divides the world into quantum phenomena and classical observers that perform measurements upon the phenomena. This provides a quite functional framework for calculating probabilities of measurement outcomes, but it lacks the generality necessary for such things as retrodiction, and...

Broad Histogram Algorithm Comparison for the Square Well Fluid

Creator:: Simpson, Tanner T.
Abstract:: Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...

Computing Wavefunctions of Silicon Donor Qubits with Density Functional Theory

Creator:: Almulla, Yousif Waleed
Abstract:: Silicon based quantum computing is an attractive approach to large-scale quantum computation due to the significant success of the modern semiconductor fabrication industry. Despite many advances in silicon quantum computing since its inception in 1998, there remains no software for efficiently designing candidate silicon quantum computing devices. Such a development...

Spectral Analysis of Upper Ocean Surface Wave Structure using χSOLO Floats in the Bay of Bengal

Creator:: Ball, Matthew S.
Abstract:: Surface waves play a vital role in air-sea interactions, and being able to easily measure them in-situ validates and improves predictive models. Here, we diagnose surface wave properties in the Bay of Bengal using modified vertical SOLO II profiling floats, which are regularly used as part of the Argo ocean...

Off-Axis Gamma Ray Burst Contribution to the Diffuse Gamma Ray Background in the 100-600 keV Range

Creator:: Hodges, Isaac
Abstract:: Gamma ray bursts (GRBs) are short, intense pulses of gamma rays that emit radiation in a narrow beam. Unless the beam is oriented towards the observer, it is often difficult to resolve the bursts against the diffuse gamma ray background (DGRB). The DGRB is a measured source of gamma rays...

Organic Semiconductors : Incorporating Xylindein into (Opto)Electronic Devices

Creator:: Rath, Jeremy J.
Abstract:: This research investigates the electronic properties of a fungi-derived pigment, xylindein as a novel sustainable material for organic electronics. Xylindein molecules were characterized in solution and in film. Absorption spectra and (photo)luminescence spectra were taken at various excitation wavelengths. Xylindein’s molecular properties were computed with the Gaussian 09 software suite....

High Field Terahertz Spectroscopy of Optically Excited Gallium Arsenide

Creator:: Compeau, James
Abstract:: High field time-domain terahertz spectroscopy (TDS) is used to determine the time dependent transmission and the time-delay and optical-power dependent conductivity of a wafer of gallium arsenide (GaAs). Gallium arsenide is a direct band-gap semiconductor and has potential as a computer processor component. Analysis of the transmission of terahertz (THz)...

Quantifying the Effects of Acoustic Coupling on Advanced LIGO

Creator:: Banowetz, Katherine
Abstract:: The Laser Gravitational Wave Observatory, or LIGO, is built to observe gravitational waves as they propagate through space. Advanced LIGO is extremely sensitive to movements of the test mass as small as 10⁻²¹ m/√Hz , which allows many signals other than gravitational waves to be detected by the system. Pressure...

Design of an Optical Medium for the Simulation of Neutron Transport in Reactor Component Materials

Creator:: Konyndyk, David M.
Abstract:: The scattering of optical rays by small spherical particles bears a strong resemblance to the diffusion of fission neutrons in solid materials. This work explores the feasibility of exploiting similarities between these two systems for the purposes of reactor component analysis, education, and outreach. After a brief overview of reactor-environment...

The contact value approximation to the pair distribution function for an inhomogeneous hard sphere fluid

Creator:: Lurie-Gregg, Paho
Abstract:: We construct the contact value approximation (CVA) for the pair distribution function, g(²)(r₁, r₂), for an inhomogeneous hard sphere fluid. The CVA is an average of two radial distribution functions, which each take as input the distance between the particles, |r₂ −r₁|, and the average value of the radial distribution...
