ABSTRACT The work includes the synthesis and characterization of new complexes of mixed ligands of Schiff  bases derived from isatin with amino acids (glycine,a-alanine,L-valine,L-leucine,L-histidine and L-tryptophane) ...

Abstract A novel Schiff base (L) was synthesized via the condensation of folic acid with salicylaldehyde, and its copper (II) complex (Cu–L complex) was subsequently prepared, exhibiting notable biological activity. Co...

Purpose — This study investigates the impact of economic complexity on income levels across countries at different stages of economic development, with particular emphasis on how these effects vary across the income di...

The article presents a brief description of the results of a study of various aspects of the economic security of business entities in the petrochemical complex. The study is aimed at solving the current scientific and p...

Abstract Unmanned Aerial Vehicle (UAV) operations confront complex systemic risks that challenge traditional analytical methods. This paper develops a hierarchical Bayesian Network (BN) to quantitatively model these risk...

"In the context of time series analysis considerable effort has been directed towards the implementation of efficient discriminating statistical quantifiers. Very recently, a simple and fast representation space has been...

Abstract The increasing frequency of natural hazards, intensified by climate change, poses substantial challenges to sustainable development worldwide. Northern Pakistan, particularly the Hunza district, is highly suscep...

Background and Aim: Effective disinfection is critical for controlling pathogenic and opportunistic microorganisms in livestock environments. Didecyldimethylammonium chloride (DDAC), a quaternary ammonium compound, is wi...

IntroductionVisual electrophysiology, including electroretinograms (ERG) and visual evoked potentials (VEP), provides a real-time functional assessment of retinal and post-retinal pathways, complementing structural imagi...

The Bahía Blanca Estuary is a complex system of channels and tidal flats where the most important deep water harbour system of Argentina is located. The main goal of the present work was to obtain a hydrodynamic conce...

Abstract Potato crops in Bangladesh are significantly threatened by viral diseases, underscoring the need for comprehensive virome profiling to inform sustainable management strategies. In this study, we employed high-th...

Abstract Background Understanding the genetic evolution of HIV-1 Transmitted/Founder (T/F) virus is crucial for developing effective treatment and prevention strategies due to its rapid mutation and recombination rates. ...

Abstract Background Effective modeling and parametric studies strengthen analyses of the influence of cotton fiber properties on the yarn properties, which are important for developing a higher-quality product. Machine l...

Abstract Background Adequate housing is a basic human right. The many millions of people experiencing homelessness (PEH) have a lower life expectancy and more physical and mental health problems. Practical and effective ...

Abstract Esophageal cancer (EC) is a malignant tumor characterized by high incidence and mortality, and its complex pathogenesis necessitates the development of effective therapeutic strategies. In this study, we investi...

Abstract Background Hepatocellular carcinoma (HCC) is a critical condition characterized by unchecked cellular growth in the liver, often leading to systemic inflammation and organ failure. Although its complex molecular...

Mind is an essential part of human activity and the result of a biological object: brain and its neural environment in front of the external nature. Considering both conscious and unconscious activity of mind facing the ...

Introduction and aims: Oral and maxillofacial surgery (OMFS) produces complex clinical data, while artificial intelligence (AI) applications in this field remain limited despite great potential. This study aimed to map t...

Amid the convergence of technological, macroevolutionary, and demographic singularities, conventional approaches to analyzing and forecasting economic growth are increasingly losing relevance and predictive power. The su...
