Intensity Inhomogeneity Correction Of Sd-Oct Data Using Macular Flatspace, Andrew Lang, Aaron Carass, Bruno M. Jedynak, Sharon D. Solomon, Peter A. Calabresi, Jerry L. Prince

Mathematics and Statistics Faculty Publications and Presentations

Images of the retina acquired using optical coherence tomography (OCT) often suffer from intensity inhomogeneity problems that degrade both the quality of the images and the performance of automated algorithms utilized to measure structural changes. This intensity variation has many causes, including off-axis acquisition, signal attenuation, multi-frame averaging, and vignetting, making it difficult to correct the data in a fundamental way. This paper presents a method for inhomogeneity correction by acting to reduce the variability of intensities within each layer. In particular, the N3 algorithm, which is popular in neuroimage analysis, is adapted to work for OCT data. N3 works …

On The Girth And Diameter Of Generalized Johnson Graphs, Louis Anthony Agong, Carmen Amarra, John Caughman, Ari J. Herman, Taiyo S. Terada

Mathematics and Statistics Faculty Publications and Presentations

Let v > k > i be non-negative integers. The generalized Johnson graph, J(v,k,i), is the graph whose vertices are the k-subsets of a v-set, where vertices A and B are adjacent whenever |A∩B|= i. In this article, we derive general formulas for the girth and diameter of J(v,k,i). Additionally, we provide a formula for the distance between any two vertices A and B in terms of the cardinality of their intersection.

Bootcmatch: A Software Package For Bootstrap Amg Based On Graphweighted Matching, Pasqua D'Ambra, Salvatore Filipone, Panayot S. Vassilevski

Mathematics and Statistics Faculty Publications and Presentations

This article has two main objectives: one is to describe some extensions of an adaptive Algebraic Multigrid (AMG) method of the form previously proposed by the first and third authors, and a second one is to present a new software framework, named BootCMatch, which implements all the components needed to build and apply the described adaptive AMG both as a stand-alone solver and as a preconditioner in a Krylov method. The adaptive AMG presented is meant to handle general symmetric and positive definite (SPD) sparse linear systems, without assuming any a priori information of the problem and its origin; the …

Clustering And Multifacility Location With Constraints Via Distance Function Penalty Methods And Dc Programming, Mau Nam Nguyen, Thai An Nguyen, Sam Reynolds, Tuyen Tran

Mathematics and Statistics Faculty Publications and Presentations

This paper is a continuation of our effort in using mathematical optimization involving DC programming in clustering and multifacility location. We study a penalty method based on distance functions and apply it particularly to a number of problems in clustering and multifacility location in which the centers to be found must lie in some given set constraints. We also provide different numerical examples to test our method.

Political Norms, Constitutional Conventions, And President Donald Trump, Neil S. Siegel

Faculty Scholarship

This symposium Essay argues that what is most troubling about the conduct of President Trump during and since the 2016 U.S. presidential campaign is not any potential violations of the U.S. Constitution or federal law. There likely have been some such violations, and there may be more. But what is most troubling about President Trump is his disregard of political norms that had previously constrained presidential candidates and Presidents, and his flouting of nonlegal but obligatory “constitutional conventions” that had previously guided and disciplined occupants of the White House. These norms and conventions, although not “in” the Constitution, play a …

Beyond The Tipping Point: Modifying The Five C'S To Empower Transgender And Gender Expansive Youth, Jonah De Chants, Heather Kennedy, Yolanda Anyon

Faculty Research, Scholarly, and Creative Activity

Transgender people have entered an unprecedented moment of visibility in American society and across the globe. However, transgender and gender expansive youth remain vulnerable to family rejection, harassment at school, and discrimination in healthcare and employment. Positive Youth Development (PYD) is an established framework for strengths-based practice with young people that is focused on helping youth develop the skills they need to become healthy, productive adults. In this manuscript, we reconceptualize the 5 C's of PYD to address the unique needs and experiences of transgender and gender expansive youth. We also provide specific guidance for empowering service providers to help …

Historicizing Whiteness And White Supremacy, Anthony Albey Soliman

The Forum: Journal of History

From the end of the eighteenth century to the mid twentieth century, demographic changes reformulated the ideal American citizen to be a white landowning American man. My historiographical paper covers the works of four authors, discussing the centrality of race in their works. In my paper, I cover several themes that are present throughout these disparate works, such as the role of space, citizenship, and race on the peripheries of settlement, and the highly mutable nature of whiteness regarding labor and nationality. By critiquing some of the anachronistic tendencies and omissions of contingency by some historians, I display the ways …

Seventeenth-Century Foundations Of The Moral Economy Of The English Crowd, Ryan Hund

The Forum: Journal of History

The historian E.P Thompson famously described English peasant bread riots in the 18th century as based off of a shared ideal of an economy that obeyed moral rules. But where did this idea originate? I argue that conflicts over land enclosure in the seventeenth century led to peasants viewing the old nobility as defending them according to even older moral principles, a view which carried over into the later economic conflicts about which Thompson writes.

Pious And Critical Scholarly Paradigms Of The Pentateuch — During The 19th & Early 20th Centuries, Spencer Morgan

The Forum: Journal of History

This paper examines the antithesis between Christian scholarship and modern higher criticism of the Pentateuch during the 19th and early 20th centuries. During the 19th century, the popularization and eventual hegemony of the Documentary Hypothesis revolutionized the field of Biblical studies. Modern critical scholars claimed that Moses did not write the Pentateuch (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) during the 15th century BC, but rather it was the product of a later redaction of at least four separate documents: J, E, P, and D. Writing hundreds of years apart and long after Moses, their authors reflect not the ancient covenantal …

The Selected Destruction Of Concentration Camps: Why The Nazi Regime Left Some Intact, Cali Vance

The Forum: Journal of History

The Holocaust is a well-known phenomenon throughout the world. Something that is less known and less researched is the destruction of the concentration camps within the German empire. There were three main players in the aftermath of the concentration camps; the Nazi officials, the Allied forces, and the Soviets. The Nazi officials followed two paths, either destroying the camps or remaining in the camps until the liberating forces arrived. The liberators, such as the Allied forces and the Soviets, came across camps with prisoners still behind the barbed wire fences or camps that had been partially or fully abandoned and …

"Captain America Must Die": How A Super Soldier Became A Patriot, Mackenna Johnson

The Forum: Journal of History

This paper analyzes the character of Captain America in the midst of the Cold War, and particularly asks how and to what extent the character reflects his contemporary sociopolitical atmosphere. To achieve this end, I first establish the vital role of popular culture, especially comic books, in modern historical research. I then discuss the history of Captain America, the sociopolitical situation of the 1970s, and, finally, introduce the Secret Empire and Nomad storylines of the 1970s, which form the basis of my argument. The most valuable primary source in this paper is not the comic books themselves, but an interview …

Rick, Morty, And Absurdism: The Millennial Allure Of Dark Humor, Kim Koltun

The Forum: Journal of History

The purpose of this paper is to investigate the millennial generation’s appeal to dark and absurdist forms of humor, using the show Rick and Morty as a primary example. I first establish my definition of Absurdism—based on Nagel and Camus—and how Rick and Morty qualifies as an Absurdist work. I then go on to outline the popularity of the show among millennial audiences and explore its allure. There are three important sociological contexts to this explanation: the contrast between upbringing and reality, expedited modernity, and rapidly changing information structures. These set the stage for a distinctive style of humor that …

Interpreting Long Chain N-Alkyl Lipids In Lake Sediments: A Critical Evaluation Of Their Sources And Isotope Signals, Hong Yang, Qin Leng, Katelynn Howard, Kai-Lou Yue

Science and Technology Department Faculty Conference Proceedings

Stable carbon and hydrogen isotopic values of n-alkyl lipids extracted from lake sediments have been widely used for the reconstruction of ancient vegetation, climate, altitude, hydrology, etc. Compound-specific isotope analysis has taken the advantage of source-specific environmental signals from both autochthonous and allochthonous lipids, assuming that long chain n-alkyl lipids are primary derived from terrestrial plants. In recent years, substantial progresses have been made toward lipids produced by lacustrine macrophytes (aquatic plants and macro-algae) regarding their abundance, metabolism, chain length distribution, and isotope values.

Accumulating evidence indicates that long chain (C26– C31) n-alkyl lipids in lacustrine sediments are derived from …

Detection Of Trace Tetrahydrocannabinol (Thc) Through Surface Enhanced Raman Spectroscopy (Sers) On Microfabricated Platforms, Jack T Lockard

Electronic Theses and Dissertations

As an increasing number of states legalize marijuana, it will become necessary to create a method for portable detection and quantification of tetrahydrocannabinol (THC), the principal psychoactive component of cannabis. The ability to identify impaired individuals without the need for traditional drug testing could prove invaluable to law enforcement and employers. Toward this end goal, surface enhanced Raman spectroscopy (SERS) with a silver treated, silicon nanowire substrate was investigated as a method for detection. Acid wet etching of silicon with a hydrofluoric acid (HF) / silver nitrate (AgNO3) was the primary investigation method for this work. Various etching parameters were …

Behavior Of Eb Frp Masonry Bond Under Service Temperature, Zuhair Al-Aljaberi, John J. Myers, K. Chandrashekhara

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The interest in advanced composites in repairing and strengthening infrastructure systems has considerably increased, especially as the application externally bonded (EB) fiber reinforced polymer (FRP) has become more well established. Previous research on bond behavior has focused on impact of durability by considering exposure to harsh environmental conditions and testing the specimens after exposure, rather than testing bond performance during exposure. The influence of directly applying temperature on bond behavior represents an open topic that needs to be investigated in more detail. This study is one of the first studies to investigate the bond behavior when the composite is subjected …

Enhancing The Crumb Rubber Modified Asphalt's Storage Stability Through The Control Of Its Internal Network Structure, Mohyeldin Ragab, Magdy Abdelrahman

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The current research investigated the effect of the internal network structure developed in the crumb rubber modified asphalt (CRMA) on its storage stability. The authors investigated the influence of asphalt-crumb rubber modifier (CRM) interaction parameters (interaction time, interaction speed, and interaction temperature) on the development of the internal network structure in CRMA. The authors found that the existence of three dimensional (3D) network structures in the CRMA enhanced its storage stability. Fourier Transform Infrared (FTIR) Spectroscopy was utilized to determine the nature of CRM components responsible for the development of 3D network structure in the liquid phase of CRMA. This …

Assessment Of Spatiotemporal Fusion Algorithms For Planet And Worldview Images, Chiman Kwan, Xiaolin Zhu, Feng Gao, Bryan Chou, Daniel Perez, Jinag Li, Yuzhong Shen, Krzysztof Koperski, Giovanni Marchisio

Electrical & Computer Engineering Faculty Publications

Although Worldview-2 (WV) images (non-pansharpened) have 2-m resolution, the re-visit times for the same areas may be seven days or more. In contrast, Planet images are collected using small satellites that can cover the whole Earth almost daily. However, the resolution of Planet images is 3.125 m. It would be ideal to fuse these two satellites images to generate high spatial resolution (2 m) and high temporal resolution (1 or 2 days) images for applications such as damage assessment, border monitoring, etc. that require quick decisions. In this paper, we evaluate three approaches to fusing Worldview (WV) and Planet images. …

Transient Lattice Deformations Of Crystals Studied By Means Of Ultrafast Time-Resolved X-Ray And Electron Diffraction, Runze Li, Kyle Sundqvist, Jie Chen, H. E. Elsayed-Ali, Jie Zhang, Peter M. Rentzepis

Electrical & Computer Engineering Faculty Publications

Ultrafast lattice deformation of tens to hundreds of nanometer thick metallic crystals, after femtosecond laser excitation, was measured directly using 8.04 keV subpicosecond x-ray and 59 keV femtosecond electron pulses. Coherent phonons were generated in both single crystal and polycrystalline films. Lattice compression was observed within the first few picoseconds after laser irradiation in single crystal aluminum, which was attributed to the generation of a blast force and the propagation of elastic waves. The different time scales of lattice heating for tens and hundreds nanometer thick films are clearly distinguished by electron and x-ray pulse diffraction. The electron and lattice …
