This paper is a brief explanation of the 1:50,000 Quadrangle Geological Map of "Ikeda". The geology of the Ikeda district which is located in the northern part of Shikoku, is divided into basement Late Cretaceous plutonic, metamorphic, and sedimentary rocks, and covering Post-Miocene volcanic and sedimentary rocks. This area is known for the distribution of the Median Tectonic Line, which is the major geological fault in Japan. This map is not only geologically important, but also important from a disaster prevention perspective.

Times Cited Count：32 Percentile：74.76(Astronomy & Astrophysics)We report on the event structure and double helicity asymmetry (
) of jet production in longitudinally polarized collisions at = 200 GeV. Photons and charged particles were measured by the PHENIX experiment. Event structure was compared with the results from PYTHIA event generator. The production rate of reconstructed jets is satisfactorily reproduced with the next-to-leading-order perturbative QCD calculation. We measured = -0.0014 
0.0037 at the lowest 
bin and -0.0181 0.0282 at the highest bin. The measured is compared with the predictions that assume various 
distributions.

We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different collisions. We also present the scaling properties such as

Times Cited Count：5 Percentile：34.72(Nuclear Science & Technology)A phase transition edge sensor (TES) microcalorimeter was developed for the energy dispersive measurement of LX-ray photons emitted from transuranium elements. The phase transition temperature of the TES was designed to be 200 mK by using bilayer structure of Au of 120 nm thick and Ti of 50 nm thick. The Au layer of 5.0 
m thick was deposited on the Au/Ti bilayer for absorption efficiency of 50% and counting rate of 100 counts per second in the detection of LX-ray photons with the energy from 10 to 20 keV. The TES microcalorimeter was operated for the detection of LX-ray photons emitted from 
Am, 
Pu and 
Pu sources. The decay time constant of 180 s of detection signal pulses allowed the TES microcalorimeter operating with the counting rate higher than 100 counts per second. The energy resolution was obtained to be 50 eV of FWHM value for a peak corresponding to 
Np L
X-ray of 17.75 keV.

The structure of the palladium species in Pd-MCM-41 bulk before and after heat-treatment process was investigated by X-ray diffraction (XRD), X-ray absorption near edge structure (XANES) and transmission electron microscopy (TEM). On the basis of these results, the microstructures and mesoporous properties of Pd-MCM-41 were discussed. As a result, it was revealed that the obtained Pd-MCM-41 bulks possessed a high area of over 1000 m
/g and the electronic state of palladium in Pd-MCM-41 bulk is almost equal to palladium (0) metal.

Times Cited Count：29 Percentile：68.67(Physics, Applied)X-ray photoelectron spectroscopy (XPS) has been applied for size estimation of Au clusters formed by ion implantation into glassy carbon. The 4f and 5d XPS spectra reveal the presence of the cluster 0.7-2.5nm in diameter, depending on the Au concentration. The elationship between XPS 4f-binding energy shift and 5d splitting is determined for the Au clusters embedded in the carbon and found to be significantly different from the previous data for the ones supported on a carbon substrate. We suppose that this difference results from the effect of the environment around a cluster on Coulomb charging during photoemission at the final state.

Times Cited Count：2 Percentile：8.47(Physics, Applied)It is found that the surface charging during Rutherford backscattering spectrometry (RBS) of insulating sapphire samples enables us to measure the charge-state distribution of probing ions backscattered at the sapphire surface. For Cu/Au-deposited AlO samples, two components, higher and lower-energy ones, were resolved on both Cu and Au peaks in the RBS random spectrum. For single-crystalline AlO samples, a double-peak structure was clearly observed on both Al and O surface peaks in the RBS aligned spectrum. The charge-state distribution can be obtained from the intensity of each component. The results obtained here are compared with previous data for the equilibrium charge-state distribution.
