Fabrication, Characterization, And Simulation Of Graphene-Copper Electrical Conductors, Raju Prasad Ghimire

Nanoscience and Microsystems ETDs

The addition of nanocarbons to copper (Cu), specifically in the form of graphene (GN), has been shown to enhance copper's properties. GN-Cu nanocomposites can potentially achieve higher electrical, mechanical, and thermal properties compared with copper. These characteristics make GN-Cu materials interesting for several applications including but not limited to interconnects, high voltage lines, and rotating machines. Copper’s microstructure and nanoscale interfacial phenomena between the GN and Cu control charge conduction in GN-Cu materials. In this work, we investigated the possibilities of conductivity enhancement in multi-layered GN-Cu composites both theoretically (classical, quantum, and atomistic models) and experimentally.

Additionally, our work elucidates …

Investigating Applications Of Deep Learning For Diagnosis Of Post Traumatic Elbow Disease, Hugh James

McKelvey School of Engineering Graduate Student Theses & Dissertations

Traumatic events such as dislocation, breaks, and arthritis of musculoskeletal joints can cause the development of post-traumatic joint contracture (PTJC). Clinically, noninvasive techniques such as Magnetic Resonance Imaging (MRI) scans are used to analyze the disease. Such procedures require a patient to sit sedentary for long periods of time and can be expensive as well. Additionally, years of practice and experience are required for clinicians to accurately recognize the diseased anterior capsule region and make an accurate diagnosis. Manual tracing of the anterior capsule is done to help with diagnosis but is subjective and timely. As a result, there is …

Habitat Use And Diel Movements Of Silver Carp Hypophthalmichthys Molitrix In Two Southeastern Reservoirs, Levi Umland

Honors College Theses

Bigheaded carp have spread rampantly throughout the Mississippi watershed and continue to spread by navigating through rivers, locks, and dams. The long-term effects these species will have on our ecosystems and natural resources is unknown. Their movements, behavior, and general seasonal patterns are well studied within rivers. However, their movements and behavior within reservoirs is poorly understood due to their initial numbers within reservoirs being lower than in rivers. To address this gap, I investigated the distribution and movement rates of Silver Carp within two reservoirs, Kentucky Reservoir and Barkley Reservoir, and possible correlative variables, including wind, temperature, residency, sex, …

Applying Hls To Fpga Data Preprocessing In The Advanced Particle-Astrophysics Telescope, Meagan Konst

McKelvey School of Engineering Graduate Student Theses & Dissertations

The Advanced Particle-astrophysics Telescope (APT) and its preliminary iteration the Antarctic Demonstrator for APT (ADAPT) are highly collaborative projects that seek to capture gamma-ray emissions. Along with dark matter and ultra-heavy cosmic ray nuclei measurements, APT will provide sub-degree localization and polarization measurements for gamma-ray transients. This will allow for devices on Earth to point to the direction from which the gamma-ray transients originated in order to collect additional data. The data collection process is as follows. A scintillation occurs and is detected by the wavelength-shifting fibers. This signal is then read by an ASIC and stored in an ADC …

Effect Of Temperature Cycling Pretreatment On The Thermal Stability Of Sm2(Co, Fe, Zr, Cu)17 Magnets In The Mild Temperature Range, Hulin Wu, Zhimei Long, Zhongsheng Li, Kaiqiang Song, Chaoqun Li, Dalong Cong, Bin Shao, Xiaowei Liu, Jianchun Sun, Yilong Ma

Faculty, Staff and Student Publications

The irredeemable magnetic losses of Sm(Co, Fe, Zr, Cu)7.8 permanent magnets caused by oxidation are very important for their practical application. In this work, the simulated results with R2 ≥ 98% based on the data of the temperature cycling test and the long-term isothermal test for the original samples confirmed that the magnetic flux losses reached 9.38% after the 5000th cycle in range R.T.–300 °C, and 7.15% after oxidated at 180 °C for 10 years, respectively. Demagnetization curves showed that the low-temperature oxidation mainly led to the remanence attenuation, while the coercivity remained relatively stable. SEM observation and EDS …

Defective Proteostasis In Induced Pluripotent Stem Cell Models Of Frontotemporal Lobar Degeneration, Sidhartha Mahali, Rita Martinez, Melvin King, Anthony Verbeck, Oscar Harari, Bruno A Benitez, Kanta Horie, Chihiro Sato, Sally Temple, Celeste M Karch

2020-Current year OA Pubs

Impaired proteostasis is associated with normal aging and is accelerated in neurodegeneration. This impairment may lead to the accumulation of protein, which can be toxic to cells and tissue. In a subset of frontotemporal lobar degeneration with tau pathology (FTLD-tau) cases, pathogenic mutations in the microtubule-associated protein tau (MAPT) gene are sufficient to cause tau accumulation and neurodegeneration. However, the pathogenic events triggered by the expression of the mutant tau protein remain poorly understood. Here, we show that molecular networks associated with lysosomal biogenesis and autophagic function are disrupted in brains from FTLD-tau patients carrying a MAPT p.R406W mutation. We …

Color Dependence Of The Topological Susceptibility In Yang-Mills Theories, Ed Bennett, Deog Ki Hong, Jong Wan Lee, C. J.David Lin, Biagio Lucini, Maurizio Piai, Davide Vadacchino

School of Engineering, Computing and Mathematics

For Yang-Mills theories in four dimensions, we propose to rescale the ratio between topologicalsusceptibility and string tension squared in a universal way, dependent only on group factors. We applythis suggestion to SU(Nc ) and Sp(Nc ) groups, and compare lattice measurements performed by severalindependent collaborations. We show that the two sequences of (rescaled) numerical results in these twofamilies of groups are compatible with each other. We hence perform a combined fit, and extrapolate tothe common large-Nc limit.

Saving Indian Consumers From Unfair Contract Terms – The Impact Of Section 2(46), Consumer Protection Act, 2019 On The Home Buyers Industry, Shivkrit Rai

International Journal on Consumer Law and Practice

On July 24, 2020, the Central Government notified the Consumer Protection Act, 2019, thereby replacing the Consumer Protection Act, 1986. One of the most significant changes brought about in the new Act is the introduction of a provision dealing with the unfair contract. This article traces how judicial and quasi-judicial forums dealt with unfair clauses in contracts prior to the implementation of the Consumer Protection Act, 2019. This is done by discussing different nuances from Competition Commission, and Consumer Commission along with narratives from United Kingdom’s Consumer Rights Act, 2015. The author argues that an explicit provision empowering the Consumer …

Polarmix: A General Data Augmentation Technique For Lidar Point Clouds, Aoran Xiao, Jiaxing Huang, Dayan Guan, Kaiwen Cui, Shijian Lu, Ling Shao

Computer Vision Faculty Publications

LiDAR point clouds, which are usually scanned by rotating LiDAR sensors continuously, capture precise geometry of the surrounding environment and are crucial to many autonomous detection and navigation tasks. Though many 3D deep architectures have been developed, efficient collection and annotation of large amounts of point clouds remain one major challenge in the analytics and understanding of point cloud data. This paper presents PolarMix, a point cloud augmentation technique that is simple and generic but can mitigate the data constraint effectively across different perception tasks and scenarios. PolarMix enriches point cloud distributions and preserves point cloud fidelity via two cross-scan …

Towards Improving Calibration In Object Detection Under Domain Shift, Muhammad Akhtar Munir, Muhammad Haris Khan, M. Saquib Sarfraz, Mohsen Ali

Computer Vision Faculty Publications

With deep neural network based solution more readily being incorporated in real-world applications, it has been pressing requirement that predictions by such models, especially in safety-critical environments, be highly accurate and well-calibrated. Although some techniques addressing DNN calibration have been proposed, they are only limited to visual classification applications and in-domain predictions. Unfortunately, very little to no attention is paid towards addressing calibration of DNN-based visual object detectors, that occupy similar space and importance in many decision making systems as their visual classification counterparts. In this work, we study the calibration of DNN-based object detection models, particularly under domain shift. …

Loss Of Pex1 In Inner Ear Hair Cells Contributes To Cochlear Synaptopathy And Hearing Loss., Stephanie A Mauriac, Thibault Peineau, Aamir Zuberi, Cathleen Lutz, Gwénaëlle S G Géléoc

Faculty Research 2022

Peroxisome Biogenesis Disorders (PBD) and Zellweger syndrome spectrum disorders (ZSD) are rare genetic multisystem disorders that include hearing impairment and are associated with defects in peroxisome assembly, function, or both. Mutations in 13 peroxin (PEX) genes have been found to cause PBD-ZSD with ~70% of patients harboring mutations in PEX1. Limited research has focused on the impact of peroxisomal disorders on auditory function. As sensory hair cells are particularly vulnerable to metabolic changes, we hypothesize that mutations in PEX1 lead to oxidative stress affecting hair cells of the inner ear, subsequently resulting in hair cell degeneration and hearing loss. Global …

Thanh, Eli Whalen, Alison E. Patteson, Paul A. Janmey

Physics - All Scholarship

Vimentin intermediate !laments form part of the cytoskeleton

of mesenchymal cells, but under pathological conditions often

associatedwith in"ammation, vimentin !laments depolymerize as

the result of phosphorylation or citrullination, and vimentin

oligomers are secreted or released into the extracellular environment.

In the extracellular space, vimentin can bind surfaces of cells

and the extracellular matrix, and the interaction between extracellular

vimentin and cells can trigger changes in cellular functions,

such as activation of !broblasts to a !brotic phenotype. The

mechanism by which extracellular vimentin binds external cell

membranes and whether vimentin alone can act as an adhesive

anchor for cells is largely …

Performance Criteria For Knee-Brace Timber Frames With Mortise And Tenon Joints, Zachary J. Halisky

Theses and Dissertations

Traditional mortise and tenon timber frames have been used in modern construction for a substantial period of time with acceptable performance against weather phenomena and other hazards. However, performance criteria for this style of timber framing are not well defined in current codes and standards. To determine performance criteria for free-standing timber frames with knee-braces, three tasks were undertaken: (1) Two timber frame specimens were tested under cyclic loads to determine hysteretic behavior, damage states, and to explore rehabilitation of a damaged member using self-tapping screws. Three damage states for were identified: peg shear, tenon tearout, and post or beam …

Explainable Ai Helps Bridge The Ai Skills Gap: Evidence From A Large Bank, Selina Carter, Jonathan Hersh

Economics Faculty Articles and Research

Advances in machine learning have created an “AI skills gap” both across and within firms. As AI becomes embedded in firm processes, it is unknown how this will impact the digital divide between workers with and without AI skills. In this paper we ask whether managers trust AI to predict consequential events, what manager characteristics are associated with increasing trust in AI predictions, and whether explainable AI (XAI) affects users’ trust in AI predictions. Partnering with a large bank, we generated AI predictions for whether a loan will be late in its final disbursement. We embedded these predictions into a …
