Article Control of Collective Bursting in Small Hodgkinhuxley Neuron Clusters(2018) Borisenok, Sergey; Catmabacak, Onder; Şenel, ZeynepThe speed gradient-based control algorithm for tracking the membranepotential of Hodgkin-Huxley neurons is applied to their small clusters modeling thebasic features of an epileptiform dynamics. One of the neurons plays a role of controlelement detecting the temporal hyper-synchronization among its network companionsand switching their bursting behavior to resting. The ‘toy’ model proposed in thepaper can serve as an algorithmic basement for developing special control elements atthe scale of one or few cells that may work autonomously and are able to detect andsuppress epileptic behavior in the networks of real biological neurons.Article Computational Identification of MicroRNAs From Ssdna Viruses(2018-09-30) Demirci, Müşerref Duygu SaçarMicroRNAs (miRNAs) are post-transcriptional regulators of gene expression and the fact that they are associated with variousdisease phenotypes is one of the main reasons for their importance. The complexity of experimental detection of miRNAs dueto their characteristics led to the development of computational methods. In this work, a machine learning based approach wasapplied to identify and analyze potential miRNAs that might be originated from 60 single strand DNA (ssDNA) viruses’genomes. The results suggest that 53 of these viruses may possibly produce proper miRNA precursors. Moreover, thepossibility of these candidate miRNA precursors’ ability to generate mature miRNAs that could target human genes and viralgenomes has been tested. Overall, the outcomes of this research indicate that there might be another level of host-virusinteraction through miRNAs which requires further experimental confirmation.
