Somatic reprogramming induced by defined transcription factors is a low-efficiency process that is enhanced by p53 deficiency. So far, p21 is the only p53 target shown to contribute to p53 repression of iPSC (induced pluripotent stem cell) generation, indicating that additional p53 targets may regulate this process. Here, we demonstrate that miR-34(More)
In this paper, we propose a method for global localization in non-stationary environments, where the environment is partially or completely different from the map. We assume there is no moving object. It is difficult to detect changes when both of the self-position and the map have large uncertainties. To solve the problem, we extended Monte Carlo(More)
Mobile robot teleoperation is a method for a human user to interact with a mobile robot over time and distance. Successful teleoperation depends on how well sensor images taken by the mobile robot are visualized to the user. To enhance the efficiency and the flexibility of the visualization, an image retrieval system on such a robot's image database would(More)
In recent years, lasers are used widely in fields such as measurements, communications, and medical cares. In those fields, a device for scanning a laser beam quickly and exactly is required. In the field of measurements in particular, laser beam scanners which use a motor driven mirror such as galvanometer mirror or a polygon mirror have been employed.(More)
Power-assist robots are expected to assist the motion in daily living of physically weak persons. The concept of perception-assist has been proposed to assist the sensory ability in addition to the assist of motor ability of the user. In the perception-assist for a lower-limb power-assist robot, perception-assist can be applied to avoid the unexpected(More)
