Towards Explaining Neural Networks: Tools For Visualizing Activations And Parameters, Juan Puebla

Open Access Theses & Dissertations

There is a growing number of applications using neural networks for making decisions. However, there is a general lack of understanding of how neural networks work. Neural networks have even been described as black boxes which has led to a lack of trust in artificially intelligent programs. To remedy this, explainable artificial intelligence has risen as a means to validate the decision-making processes and the results of computer programs that use artificial intelligence. The work in this masterâ??s thesis is our contribution to explainable artificial intelligence, focusing on neural networks with the goal of helping users make more sense of …

Understanding The Kinetics Of Laser-Induced Nanowelding Of Nanoparticles And The Motility Of Bacteria When Faced With Obstacles, Ariel Rogers

Graduate Theses and Dissertations

This dissertation has two focus areas: nanoparticle nanowelding and bacteria motility in the presence of micrometer sized structures. There are two main projects for the nanoparticle nanowelding studies: “Real-time imaging of laser-induced nanowelding in solution” and “Two-color laser-induced nanostructure shape modulation.” For the real-time imaging project, I used a fluorescence microscope, a 405 nm laser, and various python packages to quantify the average size of nanowelded nanostructures as a function of time and found that the average nanostructure growth over time fit the parameters of A¯(t) ∝ c0(1−e−t/τ), where c0 represents the initial concentration of nanoparticles in the solution and …

“This Forum Is Not A Democracy”: The Role Of Norms And Moderation In Cultivating (Anti)Democratic Incel Identities, Jennifer Forestal

Political Science: Faculty Publications and Other Works

style="font-family: "Source Sans Pro", sans-serif; font-size: 14px;">Incels (short for “involuntarily celibate”) have recently gained notoriety for their aggressive, often violent, misogyny, yet incels were not always an antidemocratic social group. They thus pose a challenge for thinking about democracy and identity in (anonymous) digital environments: how can we create spaces for marginalized social groups while ensuring the resulting identities remain democratic? While many scholars point to technological affordances or corporate content moderation policies as providing some solutions, in this article I propose a more democratic approach. Drawing from incel wikis and archived forum posts from two early incel communities—IncelSupport …

Microbiota Dynamics, Metabolic And Immune Interactions In The Cervicovaginal Environment And Their Role In Spontaneous Preterm Birth, Stanely Onyango, Jia Dai Mi, Anjela Koech, Patricia Okiro, Marleen Temmerman, Peter Von Dadelszen, Rachel Marie Tribe, Geoffrey Omuse

Pathology, East Africa

Differences in the cervicovaginal microbiota are associated with spontaneous preterm birth (sPTB), a significant cause of infant morbidity and mortality. Although establishing a direct causal link between cervicovaginal microbiota and sPTB remains challenging, recent advancements in sequencing technologies have facilitated the identification of microbial markers potentially linked to sPTB. Despite variations in findings, a recurring observation suggests that sPTB is associated with a more diverse and less stable vaginal microbiota across pregnancy trimesters. It is hypothesized that sPTB risk is likely to be modified via an intricate host-microbe interactions rather than due to the presence of a single microbial taxon …

A Comparison Of The Academic Performance Of Third-Fifth Grade Students In A Title I School Using Virtual Versus Face-To-Face Instruction, Shalyn Valencia Clay

Dissertations (2016-Present)

The Center for Disease Control (CDC) did not allow elementary aged students to receive the vaccination for COVID-19 (which will be referred to as the pandemic) until the Spring of 2021. This created two environments: the face-to-face learning environment and the virtual learning environment. Teachers were thrown into a situation in which they had to consider the risks to their own health before deciding on the best way to teach a particular lesson. Virtual learning was not considered by some to be as effective as face-to-face learning. The purpose of this quantitative comparative study was to analyze the mean scores …

Beyond Corporate Greenwashing: Discourse Of A 'Just' Electric Energy Transition Materialized At The Thacker Pass Lithium Mine, Laekyn Kelley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Thacker Pass in Northern Nevada is a rich desert ecosystem with spiritual significance to local Indigenous peoples, and it is also the site for what will be, for now, the United States’ largest open-pit lithium mine. Lithium is one mineral constituent of electric batteries which are essential to current U.S. electric energy transition policy, a transition which policymakers and other public groups have called on to be done in a way which is just. However, what exactly a just electric energy transition looks like in places like Thacker Pass is under continued negotiation in theoretical and practical senses. Existing research …

Psychological Effects Of Immigration: A Comprehensive Review Exploring Social Identity, Acculturation And The Effects Of Cultural Attitudes And Systemic Factors On The Well-Being Of Immigrants, Huda Abu Nasab

Quantitative Dual-Energy Computed Tomography With Cesium As A Novel Contrast Agent For Localization Of Thermochemical Ablation In Phantoms And Ex Vivo Models, Emily A Thompson, Megan C Jacobsen, David T Fuentes, Rick R Layman, Erik N K Cressman

Faculty, Staff and Student Publications

Background: Thermochemical ablation (TCA) is a minimally invasive therapy under development for hepatocellular carcinoma. TCA simultaneously delivers an acid (acetic acid, AcOH) and base (sodium hydroxide, NaOH) directly into the tumor, where the acid/base chemical reaction produces an exotherm that induces local ablation. However, AcOH and NaOH are not radiopaque, making monitoring TCA delivery difficult.

Purpose: We address the issue of image guidance for TCA by utilizing cesium hydroxide (CsOH) as a novel theranostic component of TCA that is detectable and quantifiable with dual-energy CT (DECT).

Materials and methods: To quantify the minimum concentration of CsOH that can be positively …

Inhibition Of The Proline Metabolism Rate-Limiting Enzyme P5cs Allows Proliferation Of Glutamine-Restricted Cancer Cells, Samantha J Linder, Tiziano Bernasocchi, Bárbara Martínez-Pastor, Kelly D Sullivan, Matthew D Galbraith, Caroline A Lewis, Christina M Ferrer, Ruben Boon, Giorgia G Silveira, Hyo Min Cho, Charles Vidoudez, Stuti Shroff, Joao P Oliveira-Costa, Kenneth N Ross, Rami Massri, Yusuke Matoba, Eugene Kim, Bo R Rueda, Shannon L Stott, Eyal Gottlieb, Joaquin M Espinosa, Raul Mostoslavsky

Faculty, Staff and Student Publications

Glutamine is a critical metabolite for rapidly proliferating cells as it is used for the synthesis of key metabolites necessary for cell growth and proliferation. Glutamine metabolism has been proposed as a therapeutic target in cancer and several chemical inhibitors are in development or in clinical trials. How cells subsist when glutamine is limiting is poorly understood. Here, using an unbiased screen, we identify ALDH18A1, which encodes P5CS, the rate-limiting enzyme in the proline biosynthetic pathway, as a gene that cells can downregulate in response to glutamine starvation. Notably, P5CS downregulation promotes de novo glutamine synthesis, highlighting a previously unrecognized …
