Comparative Study of Structural and Optical Properties of Bismuth Ferrite Nanoparticles for Photovoltaic Applications Synthesized via Different Sol-Gel Methods
Abstract: Pure multiferroic bismuth ferrite (BiFeO3) nanoparticles were successfully synthesized using an energy-efficient, low-temperature sol-gel method, comparing two distinct approaches: auto-combustion and non-auto-combustion. To ensure phase stability, the precursor solution's pH was strictly maintained between 1 and 2 using ammonia solution (NH4OH), while ethylene glycol (C2H6O2) was employed as a chelating agent for the Fe3+ and Bi3+ cations. All samples underwent a final annealing process at 500 °C to promote crystallization. …

Modeling Dispersed Count Data: Evaluating the Conway–Maxwell–Poisson Regression with COVID-19 Mortality Data
Abstract: Count data are prevalent in diverse fields such as biology, healthcare, psychology, and marketing, characterized by non-negativity and inherent heteroskedasticity, often exhibiting overdispersion or underdispersion. Traditional Poisson regression, which assumes equal mean and variance, is inadequate for such dispersed data. To address this, various generalized linear models (GLMs) and their extensions, including negative binomial (NB) and Conway–Maxwell–Poisson (CMP) regressions, are utilized. This study evaluates the performance of CMP regression compared …

Designing Self-Optimizing Operating Systems: Information-Theoretic Approaches to Thread Scheduler Implementation
Abstract: Thread Level Scheduling (TLS) in multi-core and many-core processor environments represents a critical frontier in next-generation operating system design. As computing systems grow increasingly heterogeneous and concurrent, traditional scheduling strategies often rely on heuristics or localized resource metrics, frequently overlooking the deeper, quantifiable relationships and uncertainties inherent in complex concurrent workloads. This study explores the application of information-theoretic approaches, specifically entropy-based task allocation, mutual information-driven dependency analysis, and channel capacity-inspired …
