Application Of Distributed Fiber-Optic Sensing For Pressure Predictions And Multiphase Flow Characterization, Gerald Kelechi Ekechukwu

LSU Doctoral Dissertations

In the oil and gas industry, distributed fiber optics sensing (DFOS) has the potential to revolutionize well and reservoir surveillance applications. Using fiber optic sensors is becoming increasingly common because of its chemically passive and non-magnetic interference properties, the possibility of flexible installations that could be behind the casing, on the tubing, or run on wireline, as well as the potential for densely distributed measurements along the entire length of the fiber. The main objectives of my research are to develop and demonstrate novel signal processing and machine learning computational techniques and workflows on DFOS data for a variety of …

Taking The Biscuit: Defining Excessive Quantities Of Free Refreshments In A Healthcare Library, Andrew Tabner, Stuart G. Spicer, Kerryn Husk, Holly Blake, Caroline White, Suzanne Toft, Graham Johnson

Peninsula Medical School

Evidence suggests that complementary hot drinks and biscuits benefit an overworked and highly stressed healthcare workforce. But when signage in healthcare libraries asks patrons not to consume “excessive” quantities of free hot drinks and biscuits, how much is too much? Tabner and colleagues explore this resource allocation conundrumAs the festive season approaches, temperatures plummet, days shorten, and healthcare workers see glimmers of time off around the holidays, some might consider the provision of unlimited free hot drinks and biscuits a welcome token of appreciation; this is particularly the case for National Health Service staff, who are often felt to be …

Stabilization Of Mcl-1 By E3 Ligase Traf4 Confers Radioresistance, Ming Li, Feng Gao, Xiaoying Li, Yu Gan, Shuangze Han, Xinfang Yu, Haidan Liu, Wei Li

Faculty, Staff and Students Publications

The E3 ligase TNF receptor-associated factor 4 (TRAF4) is frequently overexpressed and closely related to poor prognosis in human malignancies. However, its effect on carcinogenesis and radiosensitivity in oral squamous cell carcinoma (OSCC) remains unclear. The present study found that TRAF4 was significantly upregulated in primary and relapsed OSCC tumor tissues. Depletion of TRAF4 markedly improved the sensitivity of OSCC cells to irradiation (IR) treatment, showing that tumor cell proliferation, colony formation and xenograft tumor growth were reduced. Mechanistically, IR promoted the interaction between TRAF4 and Akt to induce Akt K63-mediated ubiquitination and activation. TRAF4 knockout inhibited the phosphorylation of …

Counseling Students’ Cognitive Complexity In A Group Dynamics Course: A Thematic Analysis, John Davison, Joel F. Diambra, Marianne Woodside, William Daniel Shirley, Rebecca Gaylor

Journal of Counselor Preparation and Supervision

Counselor education researchers maintain that cognitive complexity is an important ability for counselors-in-training (CIT) and professional counselors providing individual and group counseling (Duys & Hedstom, 2000; Granello, 2010; Welfare & Borders, 2010 Wilkinson, 2011). Cognitive complexity, simply defined as it relates to counseling, represents how CIT or professional counselors assemble multiple facets of a client’s situation for use in counseling (Granello, 2010). Research has linked the ability to construct a more or less complete picture from a client’s present circumstances to counseling effectiveness (Welfare & Borders, 2010). According to Bernard and Goodyear (2019) and Granello and Underfer-Babalis (2004), cognitive complexity …

Gatekeeping And Psychological Safety: Qualitative Analysis Of Early-Career Counselor Educators, John J. S. Harrichand, Patricia L. Kimball, Krista E. Kirk, Lucy C. Phillips, Mike S. Takacs

Journal of Counselor Preparation and Supervision

Using transcendental phenomenology, researchers investigated the gatekeeping experiences of 17 early-career counselor educators working in CACREP programs. Guided by the research question: How do early-career counselor education faculty members perceive their role as a gatekeeper and balance this role, while creating a supportive learning environment for their graduate students? Three primary themes emerged: gatekeeping is challenging, psychological safety is created through intentionality, and gatekeeping and psychological safety interact

Using An Experiential Group To Promote Engagement In A Career Counseling Course, Chad Luke, Zach Budesa, Joel Diambra

Journal of Counselor Preparation and Supervision

Abstract

Career development and graduate counseling courses provide an opportunity to engage counselors-in-training in their own career development in order to evoke a parallel experience in their future clients. One approach to engaging students in these courses is through experiential education. The authors describe a pilot project using an experiential group technique embedded in a graduate-level career development and counseling course. The first author implemented a six-session group experience using peer facilitators to explore students’ own career-related attitudes and behaviors and then transfer that experience to work with future clients. The inclusion of an experiential group in a career development …

How Slavery Is Taught In Schools, Aidan Mordas

Honors Program Theses and Projects

The debate about what should be taught to school children about slavery has been around since the days of Reconstruction. During that time, it was clear that different parts of the country wanted to teach different versions of that history. In certain parts of the country, many state legislatures believed it was best for parents to have those conversations with children. While in other parts of the country, it was clear that schools wanted to teach the a complex and accurate historical account. We can see the roots of this debate in the heated, divisive responses to the Black Lives …

Aeronautics Faculty Publications

Commercial pilot numbers have been on a decline since 2009, while in parallel, pilot demands continue to rise. In order to close the gap, airlines and companies need a steady stream of pilots-in-training who have successfully graduated. However, collegiate flight training programs have had issues with low retention and low success rates of pilots-in-training. The need to understand how to retain students within collegiate flight programs and increase success rates is vital to fill the gaps present within the aviation industry. Past studies have investigated predictive factors for pilots-in-training graduation persistence and the time it takes to graduate yielding similar …

Freeze-Frames And Blanket Bans: The Unconstitutionality Of Prisons’ Denial Of Gender Confirmation Surgery To Transgender Inmates, Aranda Stathers

Dickinson Law Review (2017-Present)

It is long established that the Eighth Amendment’s prohibition against imposing cruel and unusual punishments requires prisons to adequately address their inmates’ medical needs. Inmates identifying with the LGBTQ+ community are not exempt from this constitutional mandate. Trans inmates with gender dysphoria require specific treatment, including, but not limited to, gender confirmation surgery. While courts acknowledge that prisons owe a duty to provide some transition-related care, the extent of that duty remains contested. With no guidance from Congress or the Supreme Court, the constitutionality of prisons’ denial of gender confirmation surgery is in the hands of the circuit courts, which …

Meaningless Dna: Moore’S Inadequate Protection Of Genetic Material, Natalie Alexander

Dickinson Law Review (2017-Present)

Moore v. Regents of the University of California represents the seminal case regarding the protection of genetic material. In this case, the California Supreme Court held that patients do not retain property rights in their excised genetic material; instead, informed consent laws serve as genetic material’s only protection. Many states have accepted the Moore court’s decision not to extend property rights to genetic material, and most states choose to protect genetic material through informed consent alone. Moore and informed consent do not adequately protect genetic material, creating unjust results in which “donors” of genetic material have little to no recourse …

Navigating Beyond The Lodestar: Borrowing The Federal Sentencing Guidelines To Provide Fee-Shifting Predictability, Matthew Ahn

Dickinson Law Review (2017-Present)

The lodestar has been the dominant calculation method for fee-shifting awards for nearly 40 years. But the lodestar has numerous persistent issues: it leads to extra litigation and judicial effort, it results in highly variable fee awards, and it incentivizes plaintiffs’ attorneys to bill extravagantly and reject settlement. This Article argues that these issues with the lodestar, along with many others, result from a mismatch between the lodestar and the purpose of the underlying fee-shifting statutes, which is to encourage attorneys to bring suits that would not normally be economically viable. Encouraging attorneys to do so requires the fee awards …

Amplifying Their Voices: Equity And Assistive Technology For Children With Disabilities, Rosemary Queenan

Dickinson Law Review (2017-Present)

Assistive technology devices are crucial to the educational development of children who suffer from hearing loss. For some hearing-impaired children, access to hearing aids is vital to their ability to acquire language, develop speech, and socialize. Yet many hard of hearing children are unable to acquire hearing aids because most insurance policies do not cover them. Access to assistive technology devices for hard of hearing individuals has been the subject of long-standing controversy. The law recognizes the benefits of assistive technology devices and includes them within the scope of services school districts may be required to provide in order to …

Acute myeloid leukemia (AML) is a heterogeneous disease that accounts for ~20% of all childhood leukemias, and more than 40% of children with AML relapse within three years of diagnosis. Although recent efforts have focused on developing a precise medicine-based approach towards treating AML in adults, there remains a critical gap in therapies designed specifically for children. Here, we present ex vivo drug sensitivity profiles for children with de novo AML using an automated flow cytometry platform. Fresh diagnostic blood or bone marrow aspirate samples were screened for sensitivity in response to 78 dose conditions by measuring the reduction in …

A Hybrid Artificial Intelligence Model For Detecting Keratoconus, Zaid Abdi Alkareem Alyasseri, Ali H. Al-Timemy, Ammar Kamal Abasi, Alexandru Lavric, Husam Jasim Mohammed, Hidenori Takahashi, Jose Arthur Milhomens Filho, Mauro Campos, Rossen M. Hazarbassanov, Siamak Yousefi

Machine Learning Faculty Publications

Machine learning models have recently provided great promise in diagnosis of several ophthalmic disorders, including keratoconus (KCN). Keratoconus, a noninflammatory ectatic corneal disorder characterized by progressive cornea thinning, is challenging to detect as signs may be subtle. Several machine learning models have been proposed to detect KCN, however most of the models are supervised and thus require large well-annotated data. This paper proposes a new unsupervised model to detect KCN, based on adapted flower pollination algorithm (FPA) and the k-means algorithm. We will evaluate the proposed models using corneal data collected from 5430 eyes at different stages of KCN severity …

Roles Of Individual Protein In De Novo Polycomb Protein Recruitment, Piao Ye

Biological Sciences Theses and Dissertations

Polycomb Group (PcG) proteins are evolutionarily conserved epigenetic transcriptional regulators that maintain the transcriptional repression of silenced genes by maintaining heritable chromatin states. PcG proteins first discovered as repressors of Hox genes in Drosophila, later were shown to regulate a wide range of genes. In mammals, PcG proteins are involved in maintaining pluripotent state of stem cells and controlling cell differentiation. Misexpression of PcG protein leads to cancers like lymphoma and melanoma. PcG proteins maintain rather than initiate transcriptional repression, once PcG – mediated repression is established it can be maintained through an unlimited number of cycles. Most studies of …

Protection And Control Of Electric Power Grid Under High Penetration Of Ders, Binod Prasad Poudel

Electrical and Computer Engineering ETDs

Modernizing power grids with communication-based technologies has introduced new challenges to the operation of the grid, especially when the communication network experiences failure or data is corrupted during the transfer. This issue is studied in this dissertation from the control and protection perspective. First, the cyber attack detection and mitigation of distributed control of microgrids is addressed when the distributed energy resources (DER) are exposed to false data injection attacks. A cyber-threat detection technique is proposed based on Kullback-Liebler divergence-based criterion. This criterion with a threshold can detect the misbehavior of a compromised DER control unit and, consequently, calculates the …

An Efficient Integrated Circuit Simulator And Time Domain Adjoint Sensitivity Analysis, Jiahua Li

Electrical Engineering Theses and Dissertations

In this paper, we revisit time-domain adjoint sensitivity with a circuit theoretic approach and an efficient solution is clearly stated in terms of device level. Key is the linearization of the energy storage elements (e.g., capacitance and inductance) and nonlinear memoryless elements (e.g., MOS, BJT DC characteristics) at each time step. Due to the finite precision of computation, numerical errors that accumulate across timesteps can arise in nonlinear elements.

Silicon Photonics Trench Coupler Design, Foundry Fabrication, And Characterization, Evan Stewart

Mechanical Engineering Research Theses and Dissertations

In this thesis, compact 2-by-2 and 4-by-4 trench couplers in the silicon photonics material system have been designed, fabricated, and tested. The couplers operate on the principle of frustrated total internal reflection, allowing a footprint significantly smaller than industry standard y-couplers. As photonic integration evolves, larger scales of integration will benefit from such reduction in component size. The couplers were manufactured at the AIM silicon photonics foundry using processes available to multi-project wafer runs. The characterization of the trench couplers involves novel use of U-turns to provide efficiency estimates. For this generation of trench coupler, the experimental loss is measured …

Potential Benefits Of The Campus Outdoor Built Environment On Student Stress, Leading To Improved Retention, Kevin Dilliard

Graduate Liberal Studies Theses and Dissertations

University landscape managers often ask themselves, are they making a difference? Since what they do is not a revenue-generating department, how can they validate their true worth beyond making the campus beautiful, which is excellent, but what added value do they bring? As is common practice, when economic times get tough, the landscape department budget is one of the first to be cut, but is that the wisest thing to do? This research was intended to explore the concept that the services landscape managers provide have a return on investment by providing an environment in which students can thrive and …

Regression Modeling Of Complex Survival Data Based On Pseudo-Observations, Rong Rong

Statistical Science Theses and Dissertations

The restricted mean survival time (RMST) is a clinically meaningful summary measure in studies with survival outcomes. Statistical methods have been developed for regression analysis of RMST to investigate impacts of covariates on RMST, which is a useful alternative to the Cox regression analysis. However, existing methods for regression modeling of RMST are not applicable to left-truncated right-censored data that arise frequently in prevalent cohort studies, for which the sampling bias due to left truncation and informative censoring induced by the prevalent sampling scheme must be properly addressed. Meanwhile, statistical methods have been developed for regression modeling of the cumulative …
