Research ArticleOpen accessIn the abstractDeep Learning-Based Spectrum Sensing in Cognitive Radio Networks using Stacked LSTM: Performance Analysis of SNR and BERKavitha Veerappan, Seetharaman GopalakrishnanRapid evolution of wireless communication technologies and emergence of 5G networks have addressed lack of spectrum resources, highlighting the need for innovative topologies to improve the spectrum utilization. Due to this reason, Cognitive Radio (CR) has evolved as an optimized solution to overcome these difficulties by allowing dynamic spectrum access, thereby reducing the under-usage of available spectrum. Considering this, precise … …Journal of Computer Science, Vol. 21, Issue 11 · 19 Dec 2025 · 2,219 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDistribution and Risk Factors of Carbapenem-Resistant Enterobacterales in General Hospitals in South KoreaMijin Kang, Bokyeung Jung, Jaekyung KimThe emergence of Carbapenem-Resistant Enterobacterales (CRE) presents a significant global health challenge due to its high resistance to broad-spectrum β-lactam antibiotics. CRE infections are increasingly common in hospital settings and are associated with high mortality rates. In South Korea, the increase in CRE infections necessitates a detailed investigation into their distribution and risk factors to inform effective management and prevention … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 27 Mar 2025 · 5,759 accessesView PDF Cite
