Sphingosylphosphorylcholine (SPC) increased intracellular Ca 2+ concentration ([Ca ]i) and nitric oxide (NO) production in endothelial cells situ on bovine aortic valves, induced endothelium‐dependent relaxation of coronary arteries precontracted with U‐46619. The SPC‐induced vasorelaxation was inhibited by N ω ‐monomethyl‐ L ‐arginine, an inhibitor both constitutive inducible NO synthase (NOS), but not 1‐(2‐trifluoromethylphenyl) imidazole, NOS (iNOS). Immunoblotting revealed that NOS,...

We describe a 1.55 μm hydrogen cyanide (HCN) optical frequency and repetition rate stabilized mode-locked fiber laser, where the was locked to P(10) HCN absorption line 9.95328 GHz by using microwave phase-locked loop. The stability of laser reached 5 x 10-11 with an integration time τ 1 s. With bidirectional pumping scheme, output power 64.6 mW. To obtain short pulse train, average dispersion in cavity managed so that it zero around μm, resulting 0.95 ps train. In addition, stabilization...

Magnetic interactions on single-crystal AFe 2 As (A: Eu and Sr) were studied by 57 Fe Mössbauer spectroscopy. An abrupt appearance of the effective magnetic hyperfine field ( B eff ) is observed at spin density wave transition temperature (∼190 K for ∼200 in both samples. The value EuFe shows a small but significant increase around Néel T N (=19 K) 2+ sublattice, while SrFe almost saturates lower temperatures. Consistent with this, isomer shift indicates an anomalous dependence below...

This study aimed to map and analyze the spatial pattern of surface deformation associated with 2024 Noto Peninsula earthquake (Mw7.5) using structure-from-motion/multi-view-stereo (SfM–MVS), an advanced photogrammetric technique. The analysis was conducted digital aerial photographs a ground pixel dimension 0.2 m (captured day after earthquake). Horizontal locations GCPs were determined pre-earthquake data remove wide-area horizontal crustal component. elevations corrected by incorporating...

Abstract We describe the preparation of [(100 − y)/4](SrO–BaO–2Nb2O5)–yP2O5 (SBNPy) glasses and glass-ceramics with Sr0.5Ba0.5Nb2O6 (SBN50) phase, using a conventional process, analysis chemical stability materials in water. The SBNPy consist orthophosphate (Q0) pyrophosphate (Q1) units strongly delocalized P=O bonds. Because presence these phosphate units, obtained this study show no weight changes, even after exposure to water at 70 °C for 100 h. hypothesize that lack chains within glass...

Multiple layers of aluminum silicate and SiO2 are deposited at room temperature (RT) by repeating a combination aluminum-silicate atomic layer deposition (ALD) plural number ALDs. The RT-ALD is performed using precursors tris(dimethylamino)silane trimethyl (TMA). oxidizing gas plasma excited humidified Ar. A cross-sectional transmission electron microscope angle resolved x-ray photoelectron spectroscopy suggest that from the TMA molecule diffused to form an with Al rich surface RT. film...

Natural fiber twisted yarn has high potential as a reinforcement of green composites, because the is produced continuous form, which necessary for exhibiting reinforcing mechanism in composite. In yarn, spun filaments meander from surface to inner along axis. This phenomenon called 'migration', and structural mechanics been developed by taking an ideal migration into consideration. mechanics, tensile properties are often expressed function twist angle, while structure depends strongly on...

Room temperature (RT) atomic layer deposition (ALD) of ZnO is developed by using a precursor dimethyl zinc (DMZ) and plasma excited humidified argon. Surface reactions RT ALD are investigated an in situ observation multiple internal reflection IR absorption spectroscopy. The saturation condition DMZ argon discussed the absorbance spectra measured from sample surface. In experiment, grown film identified as fully oxidized x-ray photoelectron growth per cycle to be 0.046 nm/cycle. this paper,...

Abstract Lead‐acid batteries have been used as emergency back‐up power supplies for communication systems. These usually are charged and provide to systems when a blackout occurs. If the system is out of order during blackout, problems can be enormous. Therefore, NTT has serious about maintenance lead‐acid batteries. Since it takes longer than 20 hours check capacity battery, some other convenient battery evaluation method must established. In this paper, degradation mechanism was studied...

It is known that fatigue crack path has an influence on the life of structural components. In this study, a method predicting developed based upon superposition stress intensity factor (Green’s function solution) for problem subjecting to pair concentrated loads. This benefit give us complete closed solution, and it easy predict complex in comparison with numerical prediction by finite element (FE) analysis.

Nano crystalline zinc oxide (ZnO) is deposited by room temperature atomic layer deposition (RT-ALD) using dimethylzinc and a plasma excited humidified Ar without thermal treatments.
