The main purpose of this study is to show the sufficient control performance of semiactive tuned mass damper and to identify a suitable control method for semiactive tuned mass damper in structural vibration control. In this study, four control algorithms are considered: displacement based groundhook (DBG), velocity based groundhook (VBG), clipped optimal,(More)
Oocyte maturation and embryonic development are sensitive to DNA damage. Compared with somatic cells or oocytes, little is known about the response to DNA damage in early preimplantation embryos. In this study, we examined DNA damage checkpoints and DNA repair mechanisms in parthenogenetic preimplantation porcine embryos. We found that most of the(More)
The SUN (Sad-1/UNC-84) and KASH (Klarsicht/ANC-1/Syne/homology) proteins constitute the linker of nucleoskeleton and cytoskeleton (LINC) complex on the nuclear envelope. To date, the SUN1/KASH5 complex is known to function as meiotic-specific factors. In this study, gene-silencing methods were used to explore the roles of SUN1 and KASH5 in mouse oocytes(More)
The continuous worldwide spread of highly pathogenic avian influenza (HPAI) H5N8 viruses among wild birds and poultry is a potential threat to public health. In the present study, we investigated the genetic characteristics of recent H5N8 viruses continuously isolated from migratory birds over two winters (2013-2014 and 2014-2015) in South Korea. Genetic(More)
Applicability of the cerebellar model articulation controller ͑CMAC͒ to structural control is explored, and a training algorithm for the suppression of structural vibration is proposed. The training epochs and controlled responses by both the CMAC and the well-known multilayer neural network are compared in the numerical example. The dynamics of the(More)
