EditorialOpen accessIn the abstractBig Data and Parkinson’s Disease - from Understanding of Disease to Personalised MedicineYen F. Tai, Nicola PaveseThe advancement of information technology in recent years has generated a huge amount of datasets in all areas of scientific research. This has led to new opportunities to harness the 'Big Data' to improve our understanding of diseases - from investigating disease mechanisms to monitoring treatment responses. The Big Data approach is a data-driven and often hypothesis-free, way of studying … …Neuroscience International, Vol. 7, Issue 1 · 27 Jul 2016 · 7,755 accessesView PDFCite
Case ReportOpen accessIn the abstractThe Conceptual Principals of Bitcoin Crypto CurrencySeitim AiganymIn recent years, ideas about crypto currencies with interesting and new for today monetary principles becoming more and more popular. The crypto currencies' met different attitude to it new for the world finances principals. There are different talks. Ones think that it may improve monetary system, others think that it is a toy money that may cause instability and crash … …Journal of Computer Science, Vol. 11, Issue 10 · 2 Jan 2016 · 7,130 accessesView PDFCite
Review ArticleOpen accessIn the abstractHypermethylation and Hypomethylation of DNA: Implication for Diagnosis and Prognosis of Prostate CancerLubos Danisovic, Stanislav ZiaranProstate cancer belongs to the most common cancers and it is the second leading cause of cancer death in men. A genetic predisposition with epigenetic changes in DNA contributes to the development of the disease. DNA hypermethylation and hypomethylation belong to the most studied epigenetic changes in prostate cancer development. Both forms may lead to chromosomal instability and transcriptional gene … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 13 Jun 2015 · 6,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractHealthcare Experiences of Zabbaleen Women in Cairo, EgyptAndrea Fortson KnoppThe current political instability in the regions of North Africa and the Middle East threaten the safety of disenfranchised, vulnerable populations and the knowledge of health determinants in these people groups. Gender roles and cultural norms of the region place women in a marginalized position resulting in isolation and disconnection from society and the information or resources regarding healthcare. The … …International Journal of Research in Nursing, Vol. 6, Issue 1 · 2 Jun 2015 · 7,543 accessesView PDFCite
Research ArticleOpen accessIn the abstractSLOPE STABILITY ANALYSIS OF KALLAR-COONOOR HILL ROAD STRETCH OF THE NILGIRISP. Nalina, T. Meenambal, R. Sathyanarayan SridharThe stability of slopes is always under severe threats in many parts of Western Ghats, especially in Kallar-Coonoor hill road stretch, causing disruption, loss of human life and economy. To minimize the instability of soil slope in between Kallar-Coonoor, a critical evaluation of roads is required. The stability of slopes depends on the soil shear strength parameters such as Cohesion, … …Journal of Computer Science, Vol. 10, Issue 7 · 4 Feb 2014 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability Analysis of Southern Slope of Chenmenshan Open Pit Copper MineMohammed Mnzool, Ling Wan, Zuoan WeiChengmenshan Copper SulphurMine, one of the of the large-scale open pit mine in China, the engineering geology and hydrogeology in the Southern slope of the mine is very complicated and the contact plane between two kinds of sandstone’s form soft-weak layer. Field investigations and reports by operators demonstrated that some instability problems might occur in the southern slope which is … …Current Research in Geoscience, Vol. 3, Issue 1 · 4 Sep 2013 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Some General Ecological PrinciplesArild WikanDiscrete deterministic age-structured, stage-structured and difference delay equation population models are analysed and compared with respect to stability and nonstationary behaviour. All three models show that species with iteroparous life histories tend to be more stable than species with semelparous life histories which allow us to conclude that this must be a fairly general ecological principle. Considering iteroparity, the precocious … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 3 Jan 2013 · 6,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractReactive Power Optimization Using Quantum Particle Swarm OptimizationK. S. Chandragupta Mauryan, K. Thanushkodi, A. SakthisuganyaProblem statement: The problem of controlling a power system is not an easy task; it is subjected to various constraints. There are at risks of voltage instability problems due to highly stressed operating conditions caused by increased load demand and other constraints in the power system network. Approach: This study presents the implementation of Quantum Particle Swarm Optimization (QPSO) in … …Journal of Computer Science, Vol. 8, Issue 10 · 24 Aug 2012 · 6,837 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability of Rock Pillars with Singular and Persistent DiscontinuitiesPierpaolo OresteProblem statement: The strength of rock pillars in the presence of single, persistent, natural discontinuities can seriously be compromised and lead the pillar to collapse because of instability along the discontinuity itself. Approach: A specific analysis method for this kind of problem has been set up in this study to evaluate the stability of pillars and to determine the dimension … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 6,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Voltage Stability by Optimal Location of Static Var Compensator Using Genetic Algorithm and Particle Swarm OptimizationR. Kalaivani, V. KamarajProblem statement: Voltage instability and voltage collapse have been considered as a major threat to present power system networks due to their stressed operation. It is very important to do the power system analysis with respect to voltage stability. Approach: Flexible AC Transmission System (FACTS) is an alternating current transmission system incorporating power electronic-based and other static controllers to enhance … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 11 May 2012 · 9,443 accessesView PDFCite
