Fast Statistical Methods For The Global Qcd Analysis Of The Proton Structure, Xiaoxian Jing

Physics Theses and Dissertations

Parton distribution functions (PDFs) quantify probabilities to find partons (quarks and gluons) in a hadron as a function of the fraction x of the hadron’s momentum carried by the parton at a given energy scale. PDFs play a critical role in precision tests of the Standard Model in Higgs boson production and other electroweak processes at the Large Hadron Collider (LHC), and in searches for physics beyond the Standard Model. PDFs are obtained by the global QCD analysis, which fits theoretical predictions to experimental measurements. PDF fitting and post-analysis are computationally intensive.

The Attraction Of Fear And The Potential Therapeutic Value Of Horror Films, Mari-Peyton Kouchinsky

Educational Specialist, 2020-current

Cinematic horror has historically had a negative reputation among its peers even though it is a genre that commercially and financially thrives. There are many different perspectives as to what motivates an individual to willingly expose themselves to horror movies, ranging from psychological and metaphorical confrontation with repressed or socially unacceptable behaviors to fulfilling a somatic, thrill-seeking desire. Whatever the motivation, there is potential for harnessing both the psychological and physical reactions for therapeutic intervention. This paper aims to provide counselors with a synthesis of information on the potential therapeutic value of cinematherapy with horror movies, focusing on the relationship …

Developing Iot-Based Geophysical Micro-Observatories Utilizing Cloud Computing, Joshua Sylvester

Computer Science and Engineering Theses and Dissertations

Instrumentation for collecting geophysical data, specifically heat flow, in lake and marine environments has been in existence for over fifty years. Despite this, the costs associated with data collection and the technological limitations of existing instrumentation can be preventative when conducting geophysical studies. Furthermore, the success rate of such studies is limited by the lack of real time data transmission capabilities when instruments are deployed for extended periods of time. As a solution to this problem we have created cost-effective and lightweight IoT-driven instrumentation and combined it with cloud computing technology facilitating real time data transmission to the cloud.

Β-Hydroxy-Β-Methylbutyrate Supplementation Promotes Antitumor Immunity In An Obesity Responsive Mouse Model Of Pancreatic Ductal Adenocarcinoma, Michael F. Coleman, Kristyn A. Liu, Alexander J. Pfeil, Suhas K. Etigunta, Xiaohu Tang, Salvador Fabela, Et. Al.

Michigan Tech Publications, Part 1

Pancreatic cancer (PDAC) is a deadly disease, exacerbated by obesity, which lacks effective therapeutic interventions. Most PDAC has a limited response to immune- and chemotherapy. Treating PDAC is made additionally challenging by the rapid emergence of muscle wasting and cachexia, which predict poor response to several therapies. We have found that dietary supplementation with β-hydroxy-β-methylbutyrate promotes immunosurveillance in PDAC tumors and protects muscle. This dietary supplement has the potential to be an important adjuvant in PDAC therapy, opening the doors to immunotherapy response.

Enhanced Security Utilizing Side Channel Data Analysis, Michael Taylor

Computer Science and Engineering Theses and Dissertations

The physical state of a system is affected by the activities and processes in which it is tasked with carrying out. In the past there have been many instances where such physical changes have been exploited by bad actors in order to gain insight into the operational state and even the data being held on a system. This method of side channel exploitation is very often effective due to the relative difficulty of obfuscating activity on a physical level. However, in order to take advantage of side channel data streams one must have a detailed working knowledge of how a …

Can Activated Titanium Interbody Cages Accelerate Or Enhance Spinal Fusion? A Review Of The Literature And A Design For Clinical Trials, Nathaniel Toop, Connor Gifford, Rouzbeh Motiei-Langroudi, Arghavan Farzadi, Daniel Boulter, Reza Forghani, H. Francis Farhadi

Neurosurgery Faculty Publications

While spinal interbody cage options have proliferated in the past decade, relatively little work has been done to explore the comparative potential of biomaterial technologies in promoting stable fusion. Innovations such as micro-etching and nano-architectural designs have shown purported benefits in in vitro studies, but lack clinical data describing their optimal implementation. Here, we critically assess the pre-clinical data supportive of various commercially available interbody cage biomaterial, topographical, and structural designs. We describe in detail the osteointegrative and osteoconductive benefits conferred by these modifications with a focus on polyetheretherketone (PEEK) and titanium (Ti) interbody implants. Further, we describe the rationale …

Arginine-Rich Polypeptides Are Potent Inhibitors Of Human Papillomavirus Infection And Powerful Tools To Investigate Viral Attachment And Entry, Jesse Mckay Young

Biomedical Sciences ETDs

HPV is the most common sexually transmitted infection. It is estimated that 80% of sexually active adults will contract an HPV infection. Thus, there is a significant need for low-cost and easily distributable HPV antivirals that can be used alongside vaccines to combat infection. Herein I have identified protamine sulfate (PS) as a potent microbicide against HPV infection. PS was agnostic to genotype and efficacious pre and post HPV exposure. PS application topically reduced HPV internalization by altering epidermal growth factor receptor (EGFR) signaling and suppressed EGFR-stimulated HPV entry. Our preliminary data also suggest that heparin binding epidermal growth factor …

Soil Moisture Dependent Runoff In A Dryland Region: An Investigation Of The Role Of Antecedent Conditions, Monitoring, And Modeling Strategies, Gerhard Schoener

Civil Engineering ETDs

Approximately 30% of the Earth’s land surface is characterized as arid or semiarid, including much of the western United States. Accurate runoff predictions are important for informed watershed management, particularly in rapidly urbanizing areas. Infiltration excess overland flow is the dominant mechanism for runoff generation in many dryland basins, and event-based infiltration or loss models are commonly used to estimate runoff. However, predictions are associated with considerable uncertainty due to the role antecedent soil moisture, an initial condition that must be set by the modeler. The objectives of my research were to (1) evaluate the impact of antecedent soil moisture …

The Impact Of Insufficient Sleep And Early Class Start Times On U.S. Air Force Academy Cadet Health And Performance, Stephanie Osborn

Masters Theses, 2020-current

Emerging adults face a set of unique obstacles that combine to make getting the recommended 7-9 hours of sleep per night a challenge. Internally, adolescents and young adults have a biologically based tendency to go to sleep and wake up later. Externally, they may participate in scheduled activities that wake them up early or keep them awake late. One primary obligation that can contribute to short sleep duration in students is early class start times. Emerging adults attending a civilian college may benefit from the ability to set their bedtimes and class schedule. However, their same-aged peers attending a military …

Optimum Area Of Semi-Natural Grassland To Maintain Maximum Butterfly And Avian Species Richness In Japan, A. Shoji, K. Kohyama, H. Sasaki

IGC Proceedings (1977-2023)

To evaluate the optimum area of semi-natural grassland to maintain maximum butterfly and avian species richness in Japan, digitalized grid data of butterfly and avian distribution, as well as vegetation distribution, throughout the country were used. After obtaining logistic regression models explaining the probabilities of occurrence of each species with semi-natural grassland area and latitude as variables, the optimum value was calculated. The expected maximum species richness of butterflies in the country was the highest in the case of about 40 square kilometers of semi-natural grassland per 100 square kilometers, though the value varied somewhat with latitude. The expected maximum …
