Incremental Cluster Validity Index-Guided Online Learning For Performance And Robustness To Presentation Order, Leonardo Enzo Brito Da Silva, Nagasharath Rayapati, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

In streaming data applications, the incoming samples are processed and discarded, and therefore, intelligent decision-making is crucial for the performance of lifelong learning systems. In addition, the order in which the samples arrive may heavily affect the performance of incremental learners. The recently introduced incremental cluster validity indices (iCVIs) provide valuable aid in addressing such class of problems. Their primary use case has been cluster quality monitoring; nonetheless, they have been recently integrated in a streaming clustering method. In this context, the work presented, here, introduces the first adaptive resonance theory (ART)-based model that uses iCVIs for unsupervised and semi-supervised …

Faculty Research, Scholarly, and Creative Activity

The Longitudinal Employer-Household Dynamics Origin-Destination Employment Statistics (LODES) are an important city planning resource in the USA. However, curating these statistics is resource-intensive, and their accuracy deteriorates when changes in population and urban structures lead to shifts in commuter patterns. Our study area is the San Francisco Bay area, and it has seen rapid population growth over the past years, which makes frequent updates to LODES or the availability of an appropriate substitute desirable. In this paper, we derive mobility flows from a set of over 40 million georeferenced tweets of the study area and compare them with LODES data. …

Antisocial Personality Disorder: A Theoretical Approach Utilizing Three Dimensions Of Power Analysis, Timothy J. Nguyen, Tara Zolnikov

Faculty Research, Scholarly, and Creative Activity

Antisocial Personality Disorder (ASPD) is often associated with high costs and burden to the rest of society; however, it remains a disorder with no evidence of effective traditional psychological interventions. This theoretical study aimed to analyze the phenomenon of power and how it may influence the conceptualization of ASPD. Data was collected through a comprehensive and systematic review of the current ASPD literature. Findings suggested ASPD as severely conceptually flawed, highly imbalanced in terms of power dynamics between professionals and people diagnosed with ASPD, absent of participants’ voices, absent of any effective traditional psychotherapy interventions, disproportionately focused on deficit-oriented strategies …

Benchmarking Compositionality With Formal Languages, Josef Valvoda, Naomi Saphra, Jonathan Rawski, Adina Williams, Ryan Cotterell Jan 2022

Benchmarking Compositionality With Formal Languages, Josef Valvoda, Naomi Saphra, Jonathan Rawski, Adina Williams, Ryan Cotterell

Faculty Research, Scholarly, and Creative Activity

Recombining known primitive concepts into larger novel combinations is a quintessentially human cognitive capability. Whether large neural models in NLP can acquire this ability while learning from data is an open question. In this paper, we investigate this problem from the perspective of formal languages. We use deterministic finite-state transducers to make an unbounded number of datasets with controllable properties governing compositionality. By randomly sampling over many transducers, we explore which of their properties contribute to learnability of a compositional relation by a neural network. We find that the models either learn the relations completely or not at all. The …

Assessment Of Combined Modality Therapy For Non-Small-Cell Lung Carcinoma: A Simulation Study Concerning Concurrent Chemo-Brachytherapy, Hadi Rezaei, Hesameddin Mostaghimi, Ali Reza Mehdizadeh

Electrical & Computer Engineering Faculty Publications

Although surgery is the treatment of choice for early-stage non-small-cell lung carcinoma, almost two-thirds of patients do not have acceptable pulmonary function for extensive surgeries. The alternative approach for this large group of patients is sublobar resection along with low-dose-rate (LDR) brachytherapy (BT). However, patients with resected lungs have a high risk of recurrence and are often treated with platinum-based (Pt-based) chemotherapy (CT). In this study, we aimed to evaluate the absorbed doses of lung and other thoracic organs, considering concurrent chemo-BT with LDR sources in two modalities: conventional vs. unconventional Pt-based CT. We used the MCNPX code for simulations …

The Key Actions Of School Leaders That Contribute To Effective Implementation Of Restorative Practice, Amy L. Starzecki Jan 2022

The Key Actions Of School Leaders That Contribute To Effective Implementation Of Restorative Practice, Amy L. Starzecki

Theses and Dissertations

A growing number of students are faced with significant social, emotional, and behavioral needs that translate into a variety of problem behaviors in schools. These behaviors often result in suspension or expulsion. Exclusionary discipline practices such as suspension and expulsion negatively impact student outcomes and achievement. Additionally, these practices are often disproportionately applied to specific student populations (i.e., students of color, students with disabilities, and boys). Schools across the United States are looking for alternatives to exclusionary discipline practices that remove students from classroom instruction. Restorative practice can be an alternative to traditional punitive discipline approaches by promoting strong interpersonal …

Faculty, Staff and Students Publications

REV-ERB agonists have shown antifibrotic effects in the heart and other organs. The function of REV-ERB in the cardiac fibroblasts remains unstudied. Here, we characterize the functional difference of REV-ERB in mouse embryonic fibroblasts and cardiac fibroblasts using genetic deletion of REV-ERBα and ß in vitro. We show that REV-ERB α/β double deleted cardiac fibroblasts have reduced viability and proliferation, but increased migration and myofibroblasts activation. Thus, REV-ERB α/β has essential cell-autonomous role in cardiac fibroblasts in maintaining them in a healthy, quiescent state. We also show that existing REV-ERB agonist SR9009 strongly suppresses cardiac fibroblasts activation but in …

Faculty Research, Scholarly, and Creative Activity

This study examines the ethics and politics of knowledge across 15 distinctive community-engaged research projects. We focus our analysis on interviews with community partners and consider their perceptions of research, academic research partners, motivations for partnering, and the benefits and challenges of community-engaged research. We highlight three themes: Community partners’ (1) motivations to know better and more systematically what they already know, (2) interests in legitimating community-based knowledge (i.e., knowledge produced beyond the academy), and (3) efforts to navigate often inflexible university timelines and budgetary processes. Our findings highlight concerns at various ethical, political, and epistemic intersections and connect to …

Bone Morphogenetic Proteins Shape TReg Cells, Piotr Kraj Jan 2022

Bone Morphogenetic Proteins Shape TReg Cells, Piotr Kraj

Biological Sciences Faculty Publications

The transforming growth factor-β (TGF-β) family includes cytokines controlling cell behavior, differentiation and homeostasis of various tissues including components of the immune system. Despite well recognized importance of TGF-β in controlling T cell functions, the immunomodulatory roles of many other members of the TGF-β cytokine family, especially bone morphogenetic proteins (BMPs), start to emerge. Bone Morphogenic Protein Receptor 1α (BMPR1α) is upregulated by activated effector and Foxp3+ regulatory CD4+ T cells (Treg cells) and modulates functions of both of these cell types. BMPR1α inhibits generation of proinflammatory Th17 cells and sustains peripheral Treg cells. This finding underscores the importance of …

A Study On Anti-Maskers, Cole Kessler, Lauren Toy

Student Publications and Presentations

In-depth interviews were conducted in September of 2021 with 15 Florida residents between the ages of 18-30 (8 males, 7 females). Our primary goal was to identify why these individuals choose not to wear face masks when required or highly recommended despite the potential legal, social, and health consequences. The researchers discovered that these individuals frame not wearing masks as physically harmless, and socially and legally acceptable. Specifically, these individuals justify their anti-masking actions using seven patterns arising from both their internal views and external influences. These patterns are: 1) Changing CDC mask wearing recommendations, 2) Mask wearing health consequences, …
