A development of humanoid robot HRP-2 is presented in this paper. a robotics platform, which we developed phase two HRP. HRP was project, had run by the Ministry Economy, Trade and Industry (METI) Japan from 1998FY to 2002FY for five years. The ability biped locomotion improved so that can cope with uneven surface, walk at third level human speed, on narrow path. whole body motion also get up robot's own self if tips over safely. In paper, appearance design, mechanisms, electrical systems,...
Abstract The Coulomb interaction among massless Dirac fermions in graphene is unscreened around the isotropic points, causing a logarithmic velocity renormalization and cone reshaping. In less symmetric materials possessing anisotropic cones with tilted axes, can provide still more exotic phenomena, which have not been experimentally unveiled yet. Here, using site-selective nuclear magnetic resonance, we find non-uniform reshaping accompanied by bandwidth reduction an emergent ferrimagnetism...
A development of humanoid robot HRP-3P, which is a HRP-3 prototype, presented in this paper. under as the succession to HRP-2, we developed phase two HRP (humanoid robotics project). One futures HRP-3P that its main mechanical and structural components are designed for protection against dust water. Another node controllers realization distributed control system. Real-time communication on Ethernet also newly between controller controllers. In paper, features electrical with specifications
Endoscopic mucosal resection (EMR) is a widely accepted treatment for early gastric cancer; however, incomplete with residual local disease and recurrences continues to be difficult problem. The aim of this study was evaluate the efficacy safety endoscopic submucosal dissection (ESD) residual/local recurrent cancer lesions after EMR.The en bloc rate, histologically complete complications, recurrence were assessed in 15 patients who underwent ESD nonlifting sign injection glycerin solution...
A series of inositol 1,4,5-trisphosphate (IPS) analogs and positional isomers was examined to explore the structure-activity relationships among Ips B-phosphatase, 3-kinase, release Ca2+.All with additional groups on 2nd position IPS inhibited hydrolysis [5-32P]IPs catalyzed by erythrocyte ghosts, a lower Ki value than seen Ips.Ips dehydroxylated at also had Ki, while 2,4,5-IP3 or cyclic(l:2),4,5-IP3 higher values.Among these compounds 2-deoxy-IPs as potent in inhibiting phosphorylation 13H]...
The deterministic near-wall turbulence model developed by Kasagi et al. (1984b) is used in a numerical analysis of turbulent heat transfer, which the unsteady conduction inside wall associated with flow unsteadiness taken into account. Unlike typical methodology based on Reynolds decomposition, algebraic expressions for three fluctuating velocities given are directly introduced governing energy equation. From results conjugate statistical quantities, such as temperature variance, flux, and...
In order to identify the mechanism responsible for formation of charge-density waves (CDW) in cuprate superconductors, it is important understand which aspects CDW's microscopic structure are generic and material-dependent. Here, we show that, at local scale probed by NMR, long-range CDW YBa2Cu3Oy unidirectional with a commensurate period three unit cells (lambda = 3b), implying that incommensurability found X-ray scattering ensured phase slips (discommensurations). Furthermore, NMR spectra...
This paper presents an advanced leg module developed for HRP-2. HRP-2 is a new humanoid robotics platform,. which we have been developing in phase two of HRP. HRP project, has launched by Ministry Economy, Trade and Industry (METI) Japan from 1998FY to 2002FY five years. The ability the biped locomotion improved so that can cope with rough terrain open air prevent possible damages robot's own self event tipping over. In this mechanisms specifications module, electrical system, simulation...
Finding correlations in a Dirac-cone material Researchers have long been on the lookout for signatures of electron-electron interactions materials whose electrons linear energy dispersions represented by Dirac cones, such as graphene. However, these effects remained frustratingly small. Hirata et al. used nuclear magnetic resonance to study layered organic α-(BEDT-TTF) 2 I 3 , which phase featuring cones is known be adjacent one with enhanced electronic correlations. The unusual temperature...
The value of the upper critical field Hc2, a fundamental characteristic superconducting state, has been subject to strong controversy in high-Tc copper-oxides. Since issue tackled almost exclusively by macroscopic techniques so far, there is clear need for local-probe measurements. Here, we use 17O NMR measure spin susceptibility $\chi_{spin}$ CuO2 planes at low temperature charge ordered YBa2Cu3Oy. We find that increases (most likely linearly) with magnetic H and saturates above values...
We present nuclear magnetic (NMR) and quadrupole (NQR) resonance magnetization data in the normal state of topological crystalline superconductor ${\mathrm{LaNiGa}}_{2}$. find no evidence significant fluctuations or enhanced paramagnetism. These results suggest that time-reversal symmetry breaking previously reported superconducting this material is not driven by strong electron correlations.
In this paper, the cooling airflow in a unidirectional ventilated open-type motor for electric vehicles (EV) was studied. Numerical fluid analysis performed on through ventilation path outside stator iron core inside frame. It is confirmed that there flow separation where air did not along surfaces. This observed visualization experiment using water instead of air. We propose new structure to prevent and confirm its effectiveness by experiment. also shown another with paths both frame...
We conducted $^{77}$Se-nuclear magnetic resonance studies of the iron-based superconductor FeSe in fields 0.6 to 19 T investigate superconducting and normal-state properties. The nuclear spin-lattice relaxation rate divided by temperature $(T_1T)^{-1}$ increases below structural transition $T_\mathrm{s}$ but starts be suppressed $T^*$, well above $T_\mathrm{c}(H)$, resulting a broad maximum at $T_\mathrm{p}(H)$. This is similar pseudogap behavior optimally doped cuprate superconductors....
