Borealin, one of the chromosomal passenger proteins, is reported to play important roles in the mitotic process. To analyze precise functions of Borealin in the mitotic phase, we applied the method of multiphoton excitation-evoked chromophore-assisted laser inactivation. Although further studies are needed, our results suggest that Borealin is required for mitosis, as previously reported. These results...
This paper develops a 3-DOF active rotational ball joint with a simple and compact mechanism, which can realize a rotation around an any-direction rotational axis with a well manipulability and can change its direction of rotational axis smoothly and arbitrarily when it is on rotating. The mechanism principle of this joint is proposed and analyzed. Then the ball joint is developed with good dynamics...
The Japanese lunar mission, SELENE (Kaguya) consists of a main satellite and two small satellites, Rstar and Vstar. In same-beam VLBI observations of Rstar and Vstar, phase fluctuations caused by atmosphere, ionosphere and instruments were reduced to a low level of 1-2 deg, and the differential phase delay between Rstar and Vstar was obtained with a very low error of 2 pico-seconds. We corrected the...
This paper presents results on nMOSFETs with the La-doped high-k/metal gate stack to see its suitability for sub-32 nm LSTP and HP applications. The 32 nm gate length transistors exhibit an excellent Ion-Ioff characteristic, and the PBTI results meet the 32 nm technology node requirement. Furthermore, for the first time, Vt variation in the La-doped high-k/metal gate stack devices is investigated...
This paper considers an optimal path generation problem that generates a path of an automobile without any collision with obstacles. The problem is formulated as a mixed integer programming problem. In the problem the obstacles and environments around the automobile can be represent as inequality conditions. A feasible set called collision avoidable set (CAS) is considered to construct a driver assist...
