The P wave velocity structure beneath the Western Pacific is found from International Seismological Center first arrival data. Special attention was paid to deep Wadati‐Benioff zone. We discretized whole mantle into blocks with finer in region of interest obtain velocities all blocks. This way discretization minimizes a problem tomographic studies regional scale: difficulty making corrections for effects outside interest. Our solution iterative alternate step relocation earthquakes, using...
Over a period of roughly 40 days, starting on 8 July 2000, caldera structure 1.7 kilometers in diameter developed by means gradual depression and expansion the summit crater at Miyake Island, Japan. At same time, very-long-period (VLP) seismic signals were observed once or twice day. Source mechanism analyses VLP show that moment tensor solutions are smooth step functions over time scale 50 seconds, with dominant volumetric change components. We model to explain signals, which vertical...
Abstract A high resolution (5 lines/mm) large area(l4inch) FLCD has been developed for use in various personal and office equipment like computer, workstation, wordprocessor desktop-publishing systems etc. The 1280 × 1120 pixel screen is simply multiplexed, thus working at a 1/1120 duty rate.
Subcrustal earthquakes occur in a slab-like zone beneath SW Japan association with the subduction of Philippine Sea plate. They generate distinct pair P and S later phases anomalously low apparent velocities about 7 4 km s1, which cannot be explained by laterally homogeneous velocity structure. These are observed for particular source–receiver geometries: sources at depths shallower than 50–60 receivers subcrustal seismic comes contact bottom continental crust. We examined nature these using...
Set intersection is one of the most important operations for many applications such as Web search engines or database management systems. This paper describes our new algorithm to efficiently find set intersections with sorted arrays on modern processors SIMD instructions and high branch misprediction penalties. Our exploits can drastically reduce mispredictions. extends a merge-based by reading multiple elements, instead just element, from each two input compares all pairs elements same...
We propose a method of waveform inversion to rapidly and routinely estimate both the moment function centroid tensor (CMT) an earthquake. In this method, is carried out in frequency domain obtain more than when solved time domain. assume pure double-couple source mechanism order stabilize solution using data from small number seismic stations. The fault slip orientations are estimated by grid search with respect strike, dip rake angles. obtained inverse Fourier transform components...
Pair-breaking effects induced by 3-MeV proton irradiations are examined in underdoped, optimally doped, and overdoped Ba${}_{1\ensuremath{-}x}$K${}_{x}$Fe${}_{2}$As${}_{2}$ single crystals terms of suppression the superconducting critical temperature ${T}_{c}$. The small residual resistivity (RR) as-grown shows presence negligible intrinsic scatterings, which makes this material a model system for studying effect artificially introduced scatterings. RR ${T}_{c}$ change linearly with dose. As...
We have fabricated (Sr,K)Fe2As2 superconducting wire through a powder-in-tube method that is combined with hot isostatic pressing technique. The transport Jc in the at 4.2 K has reached 1.0 × 105 A cm−2 under self-field, and 9.4 103 100 kOe. This first report reaches 1 round wire. Magneto-optical imaging of confirmed large intergranular critical current density core. microstructure compositional analyses imply there room for improvement value optimization fabrication process.
On 2007 March 6, an earthquake doublet occurred along the Sumatran fault, Indonesia. The epicentres were located near Padang Panjang, central Sumatra, first earthquake, with a moment magnitude (Mw) of 6.4, at 03:49 UTC and was followed two hours later (05:49 UTC) by similar size (Mw= 6.3). We studied waveform inversion analysis using data from broadband seismograph network in Indonesia (JISNET). focal mechanisms earthquakes indicate almost identical right-lateral strike-slip faults,...
We demonstrate a large enhancement of critical current density (Jc) up to 1.0x10^7 A/cm2 at 5 K under self-field in (Ba,K)Fe2As2 single crystals by irradiating 320 MeV Au ions. With the very promising potential this material mind, we have fabricated superconducting wire through powder-in-tube method combined with hot isostatic pressing technique, whose effectiveness has been proven industrial Bi2223 tapes. The Jc 4.2 reached 37 kA/cm2 and 3.0 90 kOe. Magneto-optical imaging confirmed...
Abstract Two important features in high-duty FLC matrix driving, bistability and switchablity, are studied. Bistability is destroyed certain kinds of alignment because the ionic impurity accumulation at liquid crystal surfaces. Control surface molecular configuration crucial to avoid this monostablization. Unswitchable appears if has a large spontaneous polarization. Relation between anomaly electrical properties subutrates also discussed. The possibility multiplex driving been confirmed...
A network of 10 satellite-telemetered broadband stations was established under a cooperative project between Japan and the Philippines, source analysis system based on waveform inversion regional seismograms adapted to operationalize moment tensor Philippine earthquakes. This study presents information generated by for recent damaging earthquakes: M w 6.7 Negros 7.6 offshore Samar in 2012, 7.2 Bohol 2013. Results show that event shallow NE–SW thrust faulting with small strike-slip component,...

Mobile devices (cellular phone, PDA, etc.) used by many people in their daily lives have so far been personal tools. Due to multi-functionality, however, the begun be multiple co-located situations. This paper discusses near future technologies: a mobile device with projector and intuitive manipulation techniques using video camera mounted on device. It is difficult realize small light that still retains feature of mobility, we developed system project displays tracking three-dimensional...

Abstract The terpolymerizations of maleic anhydride (MAn), vinyl sulfide (VS) and ether (VE) initiated by α.α′‐azobisisobutyronitrile were investigated in order to evaluate the reactivities VS VE toward poly(MAn) radical. Since both undergo alternative copolymerization with MAn, these approximately treated on basis free propagation complex mechanisms. From treatment mechanism which only three monomers can participate, reactivity attack radical was found be 4.24 6.63 times higher than that...
Abstract An ultra‐high‐quality MVA‐LCD has been developed using a newly designed CF. The Cr black‐matrix was replaced by multi‐layer CF resin, which also used to eliminate the conventional bead spacer. protrusions that are essential building rubbing‐less MVA panels stacked on resin coated ITO prevent electrical shorting between and TFT substrates maintain appropriate cell gap. This beadless panel improves transmittance gap uniformity. Moreover, this new design removes BM from structure...
