In this paper, a method for omnidirectional sound source tracking using a circular microphone array is proposed. The sequential updating histogram estimated every two microphones are integrated for the sound source tracking. The histogram is estimated by weighting those reliability to results obtained every adjacent microphone pair. In addition, the wrapped(More)
Oocytes in the degenerative process are suggested to be rescued and to developed to ovulation by repeated induction of superovulation using gonadotrophin (GTH). In this study, the morphology of abnormally cleaved unfertilized eggs obtained by repeated induction of superovulation in mice using PMSG/hCG was observed by scanning electron microscope. As a(More)

Unfertilized eggs showing abnormal cleavage are ovulated with repeated induction of super-ovulation. In this study, the presence or absence of the nucleus was examined in segmented blastomeres of these unfertilized eggs using Hoechst dye. Unfertilized eggs showing a morula stage-like cleavage obtained by repeated superovulation 4 times using PMSG/hCG were(More)
