Heterogametic sex chromosomes have evolved independently in various lineages of vertebrates. Such sex chromosome pairs often contain nonrecombining regions, with one of the chromosomes harboring a master sex-determining (SD) gene. It is hypothesized that these sex chromosomes evolved from a pair of autosomes that diverged after acquiring the SD gene. By(More)
It is well known that mechanical loading influences the endochondral bone formation essential for the growth and development of longitudinal bones. The question was, however, asked whether the effect of mechanical loading on the chondrocyte metabolism is dependent on the loading frequency. This study was aimed at evaluating the effect of tensile loadings(More)
TSUBAME is the fourth satellite developed in the Laboratory for Space Systems (LSS) at Tokyo Institute of Technology and Institute of Space and Astronautical Science (ISAS) in Japan Aero Exploration Agency. The 50kg TSUBAME is a demonstration microsatellite for Earth and astronomical observation technology. It is planned that TSUBAME will be launched into a(More)
Recently, the number of total knee arthroplasty (TKA) has been more than 65,000 with the aging of population in Japan. Although it is well known that the soft tissue balance is important for the TKA there is a problem that it depends much on past experiences of an examiner in clinical situation. Thus, a nonexpert doctor makes deviation of the balance due to(More)
Automatic contouring system using electrostatic capacitance sensor can sense electrostatic capacitance between a detector and patients' side space. So the system can be set it at an arbitrary distance. On the other hand, this system is so complicated that it is difficult to forecast the detector motion. We studied the difference of the distance according to(More)
