Unveiling Degradation Patterns In Dye-Sensitized Solar Cells: A Machine Learning Perspective, Ahmed Alali, Mahmoud Ashraf, Ahmad Muhammad, Sameh O. Abdellatif

Electrical Engineering

This study examines the time-dependent degradation of dye-sensitized solar cells (DSSCs) by systematically investigating several critical parameters, including TiO2 thickness, porosity, dye concentration, and iodine-based electrolyte concentration. We developed a novel figure of merit (FOM) to quantify the degradation rates, utilizing a finite element model (FEM) in COMSOL to simulate performance over time. 400 DSSC samples were fabricated, resulting in a comprehensive dataset comprising over 228,000 data points derived from experimental results and simulations. The findings reveal that PCE declines significantly over time, with an average initial efficiency of 4.0% for the DSSCs, dropping to approximately 0.5% after 360 h. …

Introduction To Sociology: Sex And Gender, Dr. Marcia Morrison Ph.D.

Open Educational Resources

Abstract

This paper explores the complex interplay between sex and gender, focusing on how societal structures, historical contexts, and cultural norms shape gender roles and expectations. Drawing on the works of influential theorists such as Margaret Mead and researchers like Maccoby and Jacklin, the discussion distinguishes between biological sex differences and socially constructed gender distinctions. The analysis highlights the pervasive influence of gender socialization through agents such as family, peers, educational institutions, and media, which collectively reinforce stereotypes and stratify opportunities for individuals. The evolution of gender stratification is traced from the post-World War II era to the present, documenting …

Synthesis And Evaluation Of Novobiocin Analogues As Potential Inhibitors Of Polymerase Theta Polθ In Dna Damage And Repair, Mohammed Essam Albuhluli

Theses and Dissertations

Killing tumors while leaving normal cells unharmed is the goal of precision cancer therapy, a challenging feat that is enabled by targeting tumor-specific vulnerabilities [1]. Targeting Polθ potentiates PARP inhibitors (PARPi) in specifically killing homology-directed repair (HDR)-deficient tumor cells and re-sensitize PARPi resistant tumor cells [1]. The induced essentiality between Polθ and HDR-deficiency underscores the value of Polθ as a therapeutic target in the context of tumors with HDR genetic mutations [1]. The helicase-like domain (HLD) is a super family 2 (SF2)-type domain with DNA-dependent ATPase activity [1]. We previously discovered that the antibiotic NVB acts as an inhibitor of …

Functional Equivariance And Backward Error Analysis, Sanah Suri

Arts & Sciences Graduate Student Theses and Dissertations

Geometric, or structure-preserving, numerical integration has long been used as a framework for studying integrators that preserve a systems invariants. In backward error analysis, the approximate numerical flow of a system is viewed as the exact flow of a modified problem, allowing us to gain qualitative insights into the behavior of the numerical solution. The preservation of conservation laws by a numerical integrator can be generalized to $F$-functionally equivariant integrators, where $F$ represents an observable of the system in consideration. This thesis describes the behavior of geometric integrators through the lens of backward error analysis. First, we extend the idea …

Modeling, Analysis, And Prediction Of Covid-19 Dynamics With Interacting Subpopulations And Implicit Behavior Using Physics-Informed Neural Networks, Naima Aubry-Romero, Alonso Ogueda-Oliva, Padmanabhan Seshaiyer

Spora: A Journal of Biomathematics

In this paper, we consider an extended SEIR compartmental model that incorporates young and old interacting subpopulations, allowing for cross-group transmission dynamics. Implicit behavioral changes are included to determine the influence of social behavior on coronavirus transmission dynamics. The basic reproduction number, the average number of secondary cases of infection produced by a single primary case, is derived for both the explicit and implicit model using the next-generation matrix method. We solve the associated differential equation systems and estimate useful parameters in the explicit model using physics-informed neural networks (PINNs). Our results point to how the PINNs approach offers an …

"It Makes It More Real.”: Teacher Candidate Perceptions Of A Clinically-Rich Middle Grades Teacher Preparation Program, Shawn A. Faulkner, Michael Dicicco

Current Issues in Middle Level Education

The persistent divide between theory and practice in teacher education has long been a subject of concern among researchers and scholars (Darling-Hammond, 2006; Zeichner, 2010). This paper explores teacher candidate perceptions of a clinically-rich (NASUP, 2021) middle grades teacher preparation program that has worked to create a “third space” (Zeichner, 2010) through a school-university partnership with a local middle school. Semi-structured interviews were conducted with teacher candidates (n=23) at the time of program completion. Findings suggest teacher candidates felt prepared and valued clinically-based activities and experiences. Teacher candidates suggest future improvements to the program should include more experiences tied to …

Tafazzin-Deficient Zebrafish Display Mitochondrial Dysfunction, Neutropenia, And Metabolic Defects Without Myopathy, Usua Oyarbide, Rebecca A. Anderson, Igor Radzikh, Jillian V. Kodger, Akshay S. Patil, Morgan Staton, Anny Mulya, Genevieve M. Crane, Silvio Litovsky, Yana I. Sandlers, Seth J. Corey

Chemistry Faculty Publications

Barth syndrome is an X-linked syndrome characterized by cardiomyopathy, skeletal myopathy, and neutropenia. This life-threatening disorder results from loss-of-function mutations in TAFAZZIN, which encodes a phospholipid-lysophospholipid transacylase located in the mitochondria inner membrane. Decreased cardiolipin levels and increased monolysocardiolipin levels perturb mitochondrial function. However, the mechanism(s) leading to myopathies and neutropenia are unknown, and no currently effective therapy exists. To address these knowledge gaps, we generated tafazzin-deficient zebrafish. Neutropenia developed 5 days post-fertilization, but surprisingly no cardiac or skeletal myopathies were detected into adulthood. tafazzin mutants displayed multiple metabolic disturbances like those observed in humans with Barth syndrome. These include …

Analysis For Idempotent States On Quantum Permutation Groups, J.P. Mccarthy

Department of Mathematics Publications

Woronowicz proved the existence of the Haar state for compact quantum groups under a separability assumption later removed by Van Daele in a new existence proof. A minor adaptation of Van Daele’s proof yields an idempotent state in any non-empty weak-* compact convolution-closed convex subset of the state space. Such subsets, and their associated idempotent states, are studied in the case of quantum permutation groups.

Exploring The Promise And Limitations Of Point-Charge-Free Potentials For Hydrocarbon Modeling, Raymond Weldon, Feng Wang

Chemistry & Biochemistry Faculty Publications and Presentations

Models for hydrated and neat hydrocarbons are developed with the adaptive force matching method using either B3LYP-D3(BJ) or MP2 as reference. Hydrocarbons, being non-polar, present an opportunity to explore the possibility of creating force fields without modeling electrostatics. For liquid methane, ethane, cyclopentane, and cyclohexene, models without partial charges achieved excellent agreement with experiments when fitted against MP2 reference with SAPT dispersion. In aqueous solutions, models without solute partial charges maintain high quality for saturated hydrocarbons but exhibit reduced accuracy for cyclohexene. Notably, liquid methane's weak intermolecular interactions make it particularly sensitive to the choice of reference method. Our findings …

School of Integrative Biological & Chemical Sciences Faculty Publications

The lifestyle of Vibrio cholerae is primarily environmental, yet a chance encounter with a human host can lead to cholera, a potentially lethal form of diarrhea. Strains belonging to O1 and O139 serogroups have pandemic potential, but the contribution of non-O1/non-O139 serovars towards the genesis of cholera remains unclear. Endemic V. cholerae lineages were investigated given several historical accounts describing cholera epidemics and sporadic, contemporary cholera-like outbreaks along the lower Rio Grande Delta (LRGD). Seven isolates were recovered from an urban segment of the Rio Grande and six from a rural segment where the river empties into the Gulf of …

Do film and television portrayals of violence cause aggressive behaviour in children, juvenile delinquency, increased crime? For more than fifty years this has been one of the most heavily studied - and heavily funded! - topics of communication research. In the United States and, to some extent, in Britain, no other question of media content has been such an important political issue. The public debate about media violence has offered to media researchers one of their most important opportunities to be directly involved in media policy discussions.

Yet, the continuing analysis of programme content by communication researchers such as George …
