Research ArticleOpen accessEvery word in the titleDynamic Weighting Technique Based Arctic Puffin Optimization for Energy Efficient Data Transmission in Wireless Sensor NetworksM. Bharathraj Kumar, S. Avinash, Prakash G. Gani, Prathapchandra ShettyWireless Sensor Networks (WSNs) are designed using various sensor nodes, which are employed for communication in diverse applications that include healthcare, industrial areas, and smart cities. Specifically, WSNs demand energy-efficient clustering and routing mechanisms that assist in extending network lifetime due to the limited battery capacity of sensor nodes. However, many existing meta-heuristic-based approaches incorporate fixed objective weights that struggle … …Journal of Computer Science, Vol. 22, Issue 9 · 10 Sep 2026 · 767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Problem of Stratigraphic Assignment of the Key Seismic Horizons on the East-Arctic Shelf and in the Area of Central Arctic UpliftsLidia Daragan-Sushchova, Lyudmila Grinko, Natalia Petrovskaya, Yuri Daragan-SushchovModern geological and geophysical studies of Central Arctic uplifts area and East-Arctic Shelf has revealed the basic problems in stratigraphic subdivision of sedimentary cover. Basic approach for subdivision of Arctic Ocean sedimentary cover is based on the wave field's characteristics and tracing of regional seismic horizons. Their age identification still depends on general geological ideas. Different correlative models of seismic-stratigraphic … …Current Research in Geoscience, Vol. 5, Issue 1 · 16 Jul 2015 · 7,993 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleETHIC IDENTIFICATION OF INDIGENOUS PEOPLE OF THE SIBERIAN ARCTICNatalia Koptseva, Vladimir KirkoThis article discusses some of the problems (population dynamics, knowledge of the native language) among indigenous peoples of the North, who live in the Krasnoyarsk region (Siberian Arctic, Russia). In their own territories began a new industrialization. Reduced opportunity for these peoples to preserve their unique culture. The necessity to take urgent regulations (laws), which should protect the rights of … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 21 Aug 2014 · 6,957 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCoreless Winter Characteristics Observed with Global Positioning System Receivers over Antarctic and Arctic RegionsWayan Suparta, Faizatul Noor Abu Bakar, Mardina AbdullahProblem statement: The most recent warming trends occurred during the winter in Polar Regions had been attracted many researchers to study its impacts, which might affect the sensitivity of climate prediction in both regions, as well as on a global basis. Approach: The aims of this study were to observe the characteristics of coreless winter events using the GPS meteorology … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 22 Jun 2012 · 7,569 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFluctuation of Brain Tissue Oxygen Partial Pressure: A Biochemical Landmark in the Arctic Ground Squirrel's Spontaneous ArousalYi Long Ma, Shu Fen Wu, Lawrence K. DuffyHibernation in the Arctic ground Squirrel (AGS) is a regulated, adaptive response to arctic environmental conditions. Problem statement: Regional brain Blood Flow (rCBF) has been observed to increase dramatically during arousal in hibernators. However, the real time dynamic change in PtO2 during arousal has not been studied, we hypothesized that PtO2 is Interdependent of Tbrain and a key component in … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 1 Feb 2012 · 7,601 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Hyperoxia on Brain Tissue Oxygen Tension in Non-Sedated, Non- Anesthetized Arctic Ground Squirrels: An Animal Model of Hyperoxic StressYilong Ma, Shufen Wu, Lawrence DuffyArctic Ground Squirrels (AGS) are classic hibernators known for their tolerance to hypoxia. AGS have been studied as a model of hypoxia with potential as a medical research model. Problem statement: Their unique resistance to the stressors of low oxygen led us to hypothesize that AGS might also be adaptable to hyperoxia. Approach: This study examined the physiological pattern associated … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF ZINC OXIDE NANOPARTICLES ON NEUROBLASTOMA SH-SY5Y CELLSJinghui Zheng, Theresia Schnurr, Kriya Dunlap et al.The Arctic and sub-arctic regions are impacted by the growth of the global nanotechnology industry and the transport of chemicals to the North. New nanotechnology industries, such as neural prothesis, are bringing nanomaterials in direct contact with neurons and glial cells. Nanomaterials have unique chemical and physical properties that may lead to toxicological effects by interfering with normal cellular metabolism. … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 4 Jul 2014 · 8,488 accessesView PDFCite
