Using Single-Particle Fluorescence Microscopy To Elucidate The Role Of Structural Distortions And Defects In The Chemical Reactivity And Photophysics Of Cesium Lead Halide Perovskite Nanocrystals, Dong Wang

Arts & Sciences Graduate Student Theses and Dissertations

Colloidal cesium lead halide perovskite nanocrystals (CsPbX3, X = Cl, Br or I) are attractive for optoelectronic applications due to their unique chemical and physical properties including high photoluminescence quantum yield, tunable bandgaps, high defect tolerance, and low-cost processibility. A facile method to tune the emission wavelength of perovskite nanocrystals is through anion exchange. For light emission applications, it is desirable to prepare CsPbX3 nanocrystals of uniform size and composition. However, the complex reaction kinetics of this chemical transformation may limit the compositional uniformity and color purity of the CsPbX3 nanocrystals produced by anion exchange when the transformation is scaled …

Racial/Ethnic Differences In The Relationship Between Wealth And Health, Sicong Sun

Brown School Graduate Student Theses and Dissertations

Racial wealth inequity is one of the most pressing social and economic issues in the United States, historically and contemporarily. Primarily due to unequal distribution of opportunity for economic advancement and mobility in addition to the accumulation of historic disadvantage endured by Black and Latinx Americans, U.S. racial wealth inequity leads to substantial racial health disparities. It is widely acknowledged that socioeconomic position (SEP) is a fundamental cause of disease and health disparities. Centering around three key constructs—race/ethnicity, wealth, and health—this dissertation had two overarching aims: (a) to investigate the relationship between wealth and health, delineating the effects of wealth …

Acoustic Radiation Force And Its Application For Cell Manipulation And Ion Channels Activation, Xiangjun Peng

McKelvey School of Engineering Graduate Student Theses & Dissertations

Sound is a stress wave that carries energy and momentum flux. Scattered sound waves can generate acoustic radiation force that can be used to manipulate particles or cells. This dissertation demonstrates the physics behind cell manipulation by ultrasound. The work begins with a detailed analysis of the mechanics of using standing surface acoustic waves to fabricate acoustic tweezers for contactless particle manipulation using acoustic radiation force. Models to design and analyze acoustic radiation force have traditionally relied on plane wave theories that cannot predict how standing surface acoustic waves can levitate cells in the direction perpendicular to the substrate. We …

Defining The Role Of Elastic Fibers In Tendon Mechanics, Jeremy D. Eekhoff

McKelvey School of Engineering Graduate Student Theses & Dissertations

Tendons serve as a linking component of the musculoskeletal system by transferring forces between muscle and bone. As such, the structural proteins of the tendon extracellular matrix are of vital importance for the tissue to function properly and maintain its mechanical integrity.

Addressing Pragmatic Challenges In Utilizing Ai For Security Of Industrial Iot, Maede Zolanvari

McKelvey School of Engineering Graduate Student Theses & Dissertations

Industrial control systems (ICSs) are an essential part of every nation's critical infrastructure and have been utilized for a long time to supervise industrial machines and processes. Today’s ICSs are substantially different from the information technology (IT) devices a decade ago. The integration of internet of things (IoT) technology has made them more efficient and optimized, improved automation, and increased quality and compliance. Now, they are a sub (and arguably the most critical) part of IoT's domain, called industrial IoT (IIoT).

In the past, to secure ICSs from malicious outside attack, these systems were isolated from the outside world. However, …

A Case Study On Hls Portability From Intel To Xilinx Fpgas, Zhili Xiao

McKelvey School of Engineering Graduate Student Theses & Dissertations

Field-programmable gate arrays (FPGAs) are a hardware accelerator option that is growing in popularity. However, FPGAs are notoriously hard to program. To this end, high-level synthesis (HLS) tools have been developed to allow programmers to design hardware accelerators with FPGAs using familiar software languages. The two largest FPGA vendors, Intel and Xilinx, support both C/C++ and OpenCL C to construct kernels. However, little is known about the portability of designs between these two platforms. In this work, we evaluate the portability and performance of Intel and Xilinx kernels. We conduct a case study, porting the Needleman-Wunsch application from the Rodinia …

Advancements In Pressurized Oxy-Combustion Process: Pollutant Control And Process Development, Piyush Kumar Verma

McKelvey School of Engineering Graduate Student Theses & Dissertations

The emission of carbon dioxide from the power industry is one of the major causes of climate change. However, it is well established that the development of human societies across the globe depends on reliable and dispatchable power, which are generally the source of these emissions. There has been a recent growth in the integration of intermittent sources such as wind and solar which are carbon free. But these intermittent sources have significant temporal changes in power production and thus lack reliability and dispatchablity. This is a complicated problem to solve. However, flexible power plants with carbon capture and storage, …

“Africa Of The Heart”: The African Experience In Derek Walcott's Omeros, Hussein Kadhum Challab

Alustath Journal for Human and Social Sciences

Derek Walcott's book-length poem Omeros won critical acclaim soon after its publication in 1990. In this poem, the world of the Caribbean is linked with that of Homer by recalling the dramas of Homer’s Iliad and Odyssey in a Caribbean setting. Africa is heavily featured in Omeros as most of the major characters of the poem who in one way or another go through the African experience. 'Return to Africa' is a recurrent theme in Derek Walcott's works. However, this kind of return is not for the sole purpose of finding their old lost homeland, but rather for establishing roots …

Satirizing Empire: Comparing Ancient China And Rome, Di Wang

Arts & Sciences Graduate Student Theses and Dissertations

Comparative scholars of the ancient Mediterranean and East Asian worlds have recently taken a serious interest in the unprecedented and simultaneous emergence of two classical empires: Rome and China. The trend, invigorated by the contemporary geopolitical development of China’s rise as a world empire challenging the post-World War II Western hegemony, has yielded new insights into the many divergences and convergences of the world’s two most enduring political and cultural systems. However, preoccupied with describing the political, cultural institutions and grand narratives of empire, scholarship has largely ignored the detractors of empire, whose ingenious expressions are as enduring as these …

Probing New Physics Beyond The Standard Model Via New Neutrino Interactions, Garv Chauhan

Arts & Sciences Graduate Student Theses and Dissertations

The Standard Model (SM) of Particle Physics provides a self-consistent quantum field theoretic framework to explain three of the four known fundamental forces (electromagnetic, weak, strong) along with classifying all known elementary particles. Since its conception in the 1960s, the SM has been one of the most tested theories of physics and has withstood all experimental batterings. In spite of these successes, there are compelling indications, both experimental and theoretical, that require us to expand our understanding of the nature beyond the SM (BSM). Arguably the most glaring indication of BSM physics is the observation of neutrino oscillations, which implies …

Quantifying Components Of Protein Translation And Metabolite Heterogeneity In Isogenic Microbial Populations, Alexander Schmitz

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cell-to-cell variation in gene expression and metabolite levels have a significant impact on ensemble productivity of microbial bioproduction. New metabolic engineering tools and approaches are needed that consider cell cultures as an amalgam of uniquely behaving individuals to improve the slow commercialization of metabolically engineered systems. Stochastic cellular process including gene expression, metabolism, and growth lead to phenotypic variation between genetically identical cells. Understanding and the ability to control microbial phenotypic variation is key to improving microbial bioproduction metrics. During protein translation, codon usage strongly influences ensemble gene expression but the effect on the variation of gene expression was not …

A Study On The Hormonal Regulation And Novel Role Of Na+ Leak Channel, Non-Selective (Nalcn) In Human Myometrial Smooth Muscle Cells, Chinwendu Amazu

Arts & Sciences Graduate Student Theses and Dissertations

During pregnancy, the uterus transitions from a quiescent state to an excitable, highly contractile state to deliver the fetus. Two important contributors essential for this transition are progesterone (P4) and estrogen (E2), which promote quiescence or contraction, respectively, by acting on the myometrial smooth muscle cells (MSMCs). While these hormones regulate uterine contractions, it is unclear how they affect electrical activity of MSMCs, which underlies uterine contractile activity. Our lab recently identified Na+ leak channel, non-selective (NALCN) as a component of the leak current in human MSMCs and showed that mice lacking NALCN in the uterus have dysfunctional labor. In …

Plasmonically-Enhanced Dna-Rna Hybrid-Based Bioassay For Amplification-Free Quantification Of Sars-Cov-2, Yuxiong Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Corona Virus Disease 2019 (COIVD-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly infectious respiratory illness. Within just a few months, it spread around the whole world and became a global pandemic. Real-time reverse-transcription polymerase chain reaction (RT-PCR) works as a gold standard method diagnosing COVID-19 with high sensitivity and specificity. But due to the programs of RT-PCR, it usually takes more than 24 hours to get the results while specialized devices are also required. False-negative results can happen as well using RT-PCR which increase the risk of spreading coronavirus. To promote quicker detection of COVID-19, …

Depression As A Moderator Of The Relationship Between Perceived Injustice And Neuropsychological Performance Validity Among Individuals Previously Diagnosed With A Concussion, Jeremiah Lum

Clinical Psychology Dissertations

Concussion is one of the most common conditions seen within rehabilitation and neuropsychology. Given that many concussions are diagnosed following litigation-associated injuries, it is unsurprising that malingered neurocognitive deficit (i.e., deliberate underperformance on cognitive instruments in the interest of secondary gain) has dominated the concussion literature. Although the identification of malingering is essential to ethical assessment, its presence or absence is not the sole determinant of performance validity as a whole. Rather, performance validity is a broad construct involving effort, which refers to examinees’ investment in performing at capacity levels; emerging research suggests this can be affected by psychological factors …
