Research ArticleOpen accessIn the author namesNeurobehavioral Potential of Cod Liver Oil in Experimental Depressed Rats: Insights into Ingestive, Cognitive, and Motor FunctionsMegha Gokul, Dimple Shet, Nayanatara Arun Kumar et al.Depression-induced variations in the metabolic and neurological components have been given more attention in research. The chronic unpredictable stress rodent model mimics daily human life stressors. This study aimed to elucidate the defensive role of cod liver oil on memory, behavioral variations, and sensorimotor coordination in the Wistar rat model of comorbid depression. Wistar albino rats were categorized into the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 6 May 2026 · 1,301 accessesView PDFCite
Research ArticleOpen accessIn the author namesAluminium-Induced Hepatotoxicity and the Protective Role of Withania somnifera (Ashwagandha) in Wistar RatsAnchana Babu, Rekha D Kini, Nayanatara Arun Kumar, Megha GokulAluminium is a widely distributed environmental contaminant whose chronic exposure leads to accumulation in multiple organs, including the liver, resulting in oxidative stress and tissue damage. When reactive oxygen species production exceeds the body's antioxidant defense capacity, cellular injury ensues — a mechanism central to aluminium-induced hepatotoxicity. Withania somnifera (Ashwagandha), an evergreen herb of the Solanaceae family widely cultivated in … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 6 Apr 2026 · 1,449 accessesView PDFCite
Review ArticleOpen accessIn the author namesA Review on Cognitive Radio for Next Generation Cellular Network and its ChallengesNandhakumar Pandi, Arun KumarCognitive Radio (CR) is considered an intelligent technology. It improves the utilization of the radio spectrum. The increasing number of new devices has resulted in growing congestion of the ISM bands. FCC issued an order only permitting unlicensed users (secondary users) to operate in white space without interfering with licensed users (primary users). Cognitive Radio Networks (CRNs) provides a solution … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 4 Apr 2017 · 8,986 accessesView PDFCite
Research ArticleOpen accessIn the author namesReduction of PAPR by Using Clipping and Filtering for Different Modulation SchemesArun Kumar, Manisha GuptaOrthogonal Frequency Division Multiplexing (OFDM) is one of the most advanced technologies for high speed data access in mobile communication. It’s significantly increases the capacity, data-rate etc. but one of its disadvantage is high Peak Average Power Ratio (PAPR) which reduce the performance of transmitter amplifier. In this study, PAPR is reduced by using a clipping and filtering technique for … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 13 Feb 2016 · 8,360 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Modulation Technique for 5G Mobile Communication SystemArun Kumar, Manisha GuptaBy the year 2020, the data traffic can be approximately increase by 30%, which cannot support by existing mobile technologies. Hence, there is a requirement of next generation wireless communication (5G) which aim to provide a high capacity, data-rate at the speed of 1Tbps. By selecting a better modulation technology, the required capacity and data-rate can be achieved. In this … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 28 Sep 2015 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Review on OFDM and PAPR Reduction TechniquesArun Kumar, Manisha GuptaOFDM is a multi carrier transmission technique where a single set of data is transmitted over a number of sub-carrier. OFDM takes the advantage of multi-path propagation and reduces the fading effect. The idea of OFDM is to split the total transmission bandwidth into a number of orthogonal subcarriers which reduces the inter-symbol-interference, power consumption and increases the capacity and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 4 Jun 2015 · 8,394 accessesView PDFCite
