Investigation Of Ferroelectric Switching Mechanisms In Boron-Substituted Aluminum Nitride, Mackenzie Porterfield

Electronic Theses and Dissertations Archive

In the pursuit of next-generation memory devices, ferroelectric materials provide a pathway for high-speed operation and non-volatility. The path to marketization for ferroelectric materials favors materials with elements common to the complementary metal-oxide-semiconductor (CMOS) production, which leads to desirability in tuning boron substituted aluminum nitride – a newly demonstrated ferroelectric with CMOS compatible composition. However, for AlBN to realize its potential, understanding and optimizing the polarization reversal process becomes necessary for further device engineering. This study investigates the role of boron in domain formation and propagation. Through first-principles calculations, we determine that introducing boron atoms along the domain boundary initiates …

Investigation Of Hyperspectral Data Unmixing And Its Impact On The Task Of Anomaly Detection, Mohammed Younis

Electronic Theses and Dissertations Archive

Hyperspectral unmixing is the process of decomposing mixed pixels into distinct spectra or endmembers. In the hyperspectral unmixing process, a linear mixture model and the Fully Constrained Least Square approach are used to estimate an abundance map, which highlights the amount of each endmember that is present in the scene. This unmixing process is essential to tasks, such as target detection, where a reference endmember is provided, and the goal is to highlight areas in the scene that correspond to that reference endmember. As the number of endmembers is important to the unmixing process, we conducted an investigation in which …

The prognosis of childhood medulloblastoma (MB) is often poor, and it usually requires aggressive therapy that adversely affects quality of life. microRNA-211 (miR-211) was previously identified as an important regulator of cells that descend from neural cells. Since medulloblastomas primarily affect cells with similar ontogeny, we investigated the role and mechanism of miR-211 in MB. Here we showed that miR-211 expression was highly downregulated in cell lines, PDXs, and clinical samples of different MB subgroups (SHH, Group 3, and Group 4) compared to normal cerebellum. miR-211 gene was ectopically expressed in transgenic cells from MB subgroups, and they were subjected …

Faculty, Staff and Student Publications

Photolabeling of intracellular molecules is an invaluable approach to studying various dynamic processes in living cells with high spatiotemporal precision. Among fluorescent proteins, photoconvertible mechanisms and their products are in the visible spectrum (400-650 nm), limiting their in vivo and multiplexed applications. Here we report the phenomenon of near-infrared to far-red photoconversion in the miRFP family of near infrared fluorescent proteins engineered from bacterial phytochromes. This photoconversion is induced by near-infrared light through a non-linear process, further allowing optical sectioning. Photoconverted miRFP species emit fluorescence at 650 nm enabling photolabeling entirely performed in the near-infrared range. We use miRFPs as …

Monte Carlo Generation Of Localized Particle Trajectories, Ivan Ahumada, James P. Edwards

School of Engineering, Computing and Mathematics

We introduce modifications to Monte Carlo simulations of the Feynman path integral that improve sampling of localized interactions. The algorithms generate trajectories in simple background potentials designed to concentrate them around the interaction region, reminiscent of importance sampling. This improves statistical sampling of the system and overcomes a long-time undersampling problem caused by the spatial diffusion inherent in Brownian motion. We prove the validity of our approach using previous analytic work on the distribution of values of the Wilson line over path integral trajectories and illustrate the improvements on some simple quantum mechanical systems.

Evaluation Of Koopman Operator Neural Decoding Scheme, Kyle Edwards

Electronic Theses and Dissertations Archive

Neural activity correlates with a wide variety of phenomena relating to the animal originating the activity. It is possible to exploit those correlations by measuring the activity and mathematically transforming it via a so-called decoding process to determine what, physically, the activity represented. The signals measured are typically nonlinear, and though classical statistical techniques exist for handling these signals, increasingly influential methods including neural networks and the Koopman operator formalism provide new avenues to explore for handling such nonlinear problems. We propose a method of decoding utilizing a neural network representation of the Koopman operator and test it on the …

Traffic Congestion Analysis Using Sir Epidemic Model, Zani Anjani Rafsanjani, Ratna Herdiana, R Heru Tjahjana, Yogi Ahmad Erlangga

All Works

In this work, we propose a mathematical model to represent traffic congestion in the street under some consideration. A congestion problem in a city highway becomes a critical issue since congestion at one point affected congestion propagation on the other points. We focus on the propagation of traffic propagation by adopting the concept of disease spread using the SIR model. We consider that the disease in traffic problems is congestion. Meanwhile, vehicles that enter the highway are susceptible to congestion. In contrast, vehicles free from traffic jams represent individuals free from disease. The SIR model can explain the spread of …

Landau-Khalatnikov-Fradkin Gauge Transformations For The Propagator And Vertex In Qed And Qed2, James Edwards

School of Engineering, Computing and Mathematics

The non-perturbative Landau-Khalatnikov-Fradkin (LKF) transformations describe how Green functions in quantum field theory transform under a change in the photon field's linear covariant gauge parameter (denoted ξ). The transformations are framed most simply in coordinate space where they are multiplicative. They imply that information on gauge-dependent contributions from higher order diagrams in the perturbative series is contained in lower order contributions, which is useful in multi-loop calculations. We study the LKF transformations for the propagator and the vertex in both scalar and spinor QED, in some particular dimensions. A novelty of our work is to derive momentum-space integral representations of …
