A reinforcement learning-driven adaptive hybrid PLC-RF communication architecture for IoT-based smart metering systems

Abstract With the rapid expansion of smart grid infrastructure, robust and scalable communication is essential to support Advanced Metering Infrastructure (AMI). This paper presents a hybrid communication architecture that combines Power Line Communication (PLC) and Radio Frequen...

Cold and hot tumors: immunological determinants, cancer-immunity cycle dysregulation, and nanotechnology-driven therapeutic approaches

Abstract Cancer remains a major global health burden and the second leading cause of mortality worldwide. Recent advances in cancer immunotherapy have emphasized the critical role of the tumor microenvironment (TME) in determining therapeutic outcomes, leading to the classificati...

Synthesis and molecular docking of novel pyrazole, pyrimidine, and pyridine derivatives as potent antimicrobial, antibiofilm, and anticancer agents

Abstract The development of novel antimicrobial and anticancer agents remains a priority due to rising drug resistance and high systemic toxicity of current treatments. A series of novel pyrazole ( 2–6 ), pyrimidine ( 7–10 ), and pyridine/oxazinone ( 11–14 ) derivatives were synt...

Lanolin in implantation of luminous polymer dots for environmental application as metal probes

Polymer dots (PDs) have become one of the potential fluorescent nanomaterials in environmental sensing because they are low-toxicity, tunable optical nanomaterials, and are cost-effective. Herein, a green and facile hydrothermal strategy was formed to nucleate luminous PDs with l...
