Structural insights and comparative electrocatalytic performance of citric acid-functionalized Luffa aegyptiaca and Pt-Pd/MWCNT-Luffa composites for the degradation of acetaminophen in aqueous media

Emerging contaminants, such as acetaminophen, pose a critical threat to aquatic ecosystems and human health due to their persistence in water and the difficulty of their removal using conventional methods. In this work, Luffa aegyptiaca biomass was valorized via citric acid funct...

Fault Diagnosis, Fault Tolerance, and Reconfiguration of Cascaded H-Bridge Multilevel Converter Applications: A Comprehensive Review

Multilevel converter topologies are used in diverse applications requiring medium-voltage and high-power ratings, such as motor drives, power quality compensators, distributed generation, solid-state transformers, and energy storage systems. This paper presents a comprehensive li...

Sequence entropy and independence in free and minimal actions

For every countable infinite group that admits \mathbb{Z} as a homomorphic image, we show that for each m\in{\mathbb{N}} , there exists a minimal action whose topological sequence entropy is \log(m) . Furthermore, for every countable infinite group G that contains a finite index...

Synthesis and Electrochemical Behavior of Nickel Sulfide-Decorated N-Doped Carbon Nanotubes: Effect of Growth Temperature

Abstract Nitrogen-doped multi-walled carbon nanotube (N-MWCNT) hybrid materials decorated with Ni-based sulfide nanoparticles were synthesized via aerosol-assisted chemical vapor deposition using benzylamine, nickelocene, and thiophene as precursors at 900 °C and 1020 °C. The inf...

Exploring the Impact of Epstein-Barr Virus and Cytomegalovirus Reactivation on COVID-19 Severity and Host Immune Response

Background: Reactivation of latent Epstein-Barr virus and cytomegalovirus is commonly observed among critically ill patients presenting with severe COVID-19. Methods: Retrospective cohort study comprising adult patients admitted to a simple hospital with COVID-19 infection from M...

Automatic Classification of Thermal Phases During Steel Oxidation via PCA and Infrared Thermography Time Series

High-temperature oxidation affects the surface condition and quality of steel products, yet automated identification of the thermal stages governing oxide-scale formation remains limited. This study evaluated whether infrared thermography time series combined with dimensionality...

Soil Yeasts from Sugarcane Agroecosystems: Nutrient Cycling and Biocontrol Potential in Agricultural Systems

Soil yeasts represent a significant component of the agricultural microbiota and possess high ecological and biotechnological potential in production systems such as those for sugarcane. This review analyses the importance of these microorganisms in fundamental processes related...

Sex Differences in Oxidative Stress and Depression-Like Behavior Following Chronic Lead Exposure from Pregnancy to Adulthood

Abstract Lead (Pb) is a neurotoxic heavy metal that crosses the placental barrier and may affect fetal development. However, the effects of chronic developmental Pb exposure on oxidative stress, stress-related endocrine responses, and depression-like behavior, particularly regard...

A hybrid Fourier–PSO model for hourly wind speed forecasting over a 4-year horizon: A tropical coastal case study

Modelling wind speed at hourly resolution over multi-year horizons remains challenging, particularly in tropical regions influenced by strong climatic variability. This study presents a hybrid Fourier–PSO framework for four-year ahead wind speed forecasting using ERA5 reanalysis...
