Multivariate degradation modeling using generalized cauchy process and application in life prediction of dye-sensitized solar cells
No full textClick on the DOI link to access this article at the publishers website (may not be free).Recently, the Generalized Cauchy (GC) process has been applied to capture a Long Memory (LM) phenomenon in product degradation modeling and life prediction. Compared with the traditional fractional Brownian motion that captures the LM using a single Hurst parameter, the GC process has two free parameters (Hurst and fractal dimension parameters) that flexibly capture both global LM and local irregularity. However, all existing GC-based degradation models are for a single Degradation Characteristic (DC). In this article, motivated by a real degradation problem of dye-sensitized solar cells that jointly exhibits multiple DCs, global LM, local irregularity and DC-wise cross-correlation, we propose a novel GC-based Multivariate Degradation Model (GC-MDM) to simultaneously capture the aforementioned effects. A maximum likelihood estimation approach is developed to estimate parameters of the GC-MDM. Subsequently, product life prediction based on the GC-MDM is developed. The proposed GC-MDM is validated through a simulation study and a physical experiment of dye-sensitized solar cells. Results show that the proposed GC-MDM fundamentally improves the life prediction accuracy in comparison with conventional degradation models which significantly misestimate the uncertainty of product life. © 2024 Elsevier LtdWichita State University, WSU; Michigan Technological University, MTU; National Science Foundation, NSF: OIA-2148878; National Science Foundation, NSF; National Aeronautics and Space Administration, NASA: 80NSSC22M0028, 80NSSC23M0100; National Aeronautics and Space Administration, NASA; U.S. Department of Energy, USDOE: DE-EE0009525; U.S. Department of Energy, USDOEThis work was supported in part by the National Science Foundation under Award OIA-2148878, the Kansas NASA EPSCoR Research Infrastructure Development Program under Grant 80NSSC22M0028, and the NASA EPSCoR Program under Grant 80NSSC23M0100 to Wichita State University.This work was supported in part by the National Science Foundation under Award OIA-2148878, the Kansas NASA EPSCoR Research Infrastructure Development Program under Grant 80NSSC22M0028, and the NASA EPSCoR Program under Grant 80NSSC23M0100 to Wichita State University, and the U.S. Department of Energy under Award DE-EE0009525 to Michigan Technological University
The geometric cobordism hypothesis
No full textClick on the DOI link to access this article at the publishers website (may not be free).This is an invited contribution to the 2nd edition of the Encyclopedia of Mathematical Physics. We review the geometric cobordism hypothesis of Grady and Pavlov, b. We survey the construction of the smooth symmetric monoidal (∞,d)-category of bordisms, the locality property for fully-extended nontopological field theories, and we sketch the proof of the geometric cobordism hypothesis. The example of 1-dimensional Riemannian field theories is also discussed. © 2025 Elsevier Ltd. All rights are reserved

Harm reduction perspectives of the opioid epidemic from Kansans, for Kansas: A thematic analysis
No full textClick on the DOI link to access this article at the publishers website (may not be free).Substantial increases in drug overdose deaths, the prevailing lack of access to care for substance use disorder, and the adverse effects of stigma and criminalization underlie the need for comprehensive evidence-based strategies that improve the health, safety, and well-being of people who use drugs. Harm reduction has emerged as a promising approach in the mitigation of substance-related harms. However, many harm reduction strategies remain illegal especially in Kansas. Eleven stakeholders, including law enforcement/criminal justice officials, state legislators, and health care professionals were interviewed to explore their perspectives on harm reduction and gather their recommendations Using reflexive thematic analysis, we developed three themes for the first research question (stigma, alternatives to criminalization, and authentic conversations and relationships) and six themes for the second research question (roadmap to a more comprehensive harm reduction, barriers to harm reduction, facilitators to harm reduction, connection of harm reduction to behavioral health reform, social determinants of health, and protection of public safety). © 2025 Taylor & Francis Group, LLC

We also proved that the truncated power function (t−⋅)+(d+1)/2 is strictly positive definite on Sd and RPd for d≥2 and t∈(0,π]. © 2024 Elsevier Inc
You got me here… now what?: Examining how university social media influences belonging uncertainty reduction in first-year students
No full textThesis (M.A.)-- Wichita State University, College of Liberal Arts and Sciences, Elliott School of CommunicationThe transition to college is a critical period marked by excitement and uncertainty, as first-year students navigate new social and academic environments. This study investigates the role of university-managed social media platforms in reducing belonging uncertainty - a phenomenon characterized by students’ concerns about fitting into their new college community. Drawing on Hossler and Gallagher’s College Choice Theory and Walton and Cohen’s concept of belonging uncertainty, this research addresses two primary questions:
1.) Does university social media play a role in reducing uncertainty for students attending higher education institutions?
2.) Which types of social media content are most effective in maintaining low levels of uncertainty?
Employing qualitative focus groups with first-year students at Wichita State University, the study explores how digital engagement via institutional social media affects students’ perceptions of belonging. Participants discussed their experiences interacting with university social media posts, identifying themes such as identity representation, authenticity, relatability, and visual clarity. Findings indicate that authentic, inclusive and relatable content, particularly student-generated posts showcasing realistic experiences- significantly reduced feelings of uncertainty and enhanced students’ sense of belonging. Conversely, overly curated or institutionally driven content intensified students’ perceptions of exclusion and uncertainty.
This study fills a gap in current literature by highlighting the potential of using social media content to function as an effective digital intervention supporting first-year student retention and engagement, especially for marginalized student population
Melodic intonation therapy via Zoom for a person with severe Broca's aphasia
No full textSecond place winner of poster presentations for Applied Sciences at the 24th Annual Undergraduate Research and Creative Activity Forum (URCAF) held in the Woolsey Hall, Wichita State University, April 25, 2025.Aphasia is a language disorder that affects a person's ability to speak and understand language due to stroke or traumatic brain injury. Melodic Intonation Therapy (MIT) is an effective evidence-based aphasia therapy approach that uses intonation and rhythmic patterns to improve verbal phrase production and overall language performance. Many research studies have shown that MIT helps people with aphasia learn useful verbal phrases and improves their standardized language test scores. However, little is known about whether MIT is effective when delivered teletherapy. Also, little is known about what people with aphasia think about their experience participating in MIT. The current research focused on the following research questions: 1) Is MIT effective when conducted via teletherapy? 2) What does the participant with aphasia think about their experience doing MIT? These questions were investigated using a mixed methods design including quantitative ratings of speech accuracy for the phrases and qualitative analysis of a post therapy interview. One participant with aphasia from stroke was included in the study. Her speech accuracy for the phrases was measured seven times before, during, and after MIT teletherapy allowing effect sizes to be calculated using a single subject multiple baseline design. The results showed that the participant increased her accuracy for intermediate and complex phrases but made no significant increase for the short, simple phrases. Thematic analysis of her post-therapy interview revealed that she preferred teletherapy on her tablet because of the independence it allowed her. Additionally, she said that she would like to do more MIT in the future and would miss the clinician. Future research should include more participants with aphasia to find out whether these results generalize to the larger population of people with aphasia
Hermeneutical injustice and epistemic basing failure; [Injusticia hermeneútica y fallo epistémico de fundamentación]
No full textThis paper introduces a problem relating to hermeneutical injustice that is grounded in epistemic basing failure. Mona Simion has recently argued for an extension of Miranda Fricker’s concept of hermeneutical injustice, to cover cases where subjects have good reasons for important beliefs available to them, but they fail to form the relevant beliefs. This paper further argues that hermeneutical injustices can arise in cases where subjects have good reasons available, and they do hold the relevant beliefs that are supported by those reasons, but they fail to hold their beliefs on the basis of the good reasons that are available to them. © PATRICK BONDY
