Times Cited Count：3 Percentile：13.75(Physics, Fluids & Plasmas)Projection images of a metal mesh produced by directional MeV electron beam together with directional proton beam, emitted simultaneously from a thin foil target irradiated by an ultrashort intense laser. The mesh patterns are projected to each detector by the electron beam and the proton beam originated from tiny virtual sources of 
20 micron meter and 10 micron meter diameters, respectively. Based on the observed quality and magnification of the projection images, we estimate sizes and locations of the virtual sources for both beams and characterize their directionalities. To carry out physical interpretation of the directional electron beam qualitatively, we perform 2D particle-in-cell simulation which reproduces a directional escaping electron component, together with a non-directional dragged-back electron component, the latter mainly contributes to building a sheath electric field for proton acceleration.

The production rate of reconstructed jets is satisfactorily reproduced with the next-to-leading-order perturbative QCD calculation. We measured = -0.0014

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：8 Percentile：49.7(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

The states close to the Fermi level are found to have a strongly mixed Mo–Fe t
character, indicating that the Fe valence is far from pure 3+. The Fe 2p
x-ray absorption spectroscopy spectra reveal the mixed-valent Fe 
–Fe
configurations, and a larger Fe component for BFMO than for SFMO, suggesting an operative double exchange interaction. The valence-band PES spectra reveal good agreement with the local-spin-density-approximation (LSDA+U) calculation.

By forming an SiC thin film on Si substrates and by thermally converting the film top surface into graphene, a graphene layer can be epitaxially formed on the Si substrates (graphene on silicon;GOS). In this method, epitaxial SiC thin films are first grown on the silicon substrate by using gas source molecular beam epitaxy. Normally, 3C-SiC(111), (110) and (100)-oriented films are grown on Si(111), (110) and (100) substrates, respectively. The surface of SiC thin films is then thermally graphitized by annealing at 1523 K in UHV to sublimate Si atoms. Not only 3C-SiC(111) but also (100) and (110) surfaces, produced epitaxial graphene as well. The Raman spectra show distinct D, G and G' bands for all these orientations. Synchrotron-radiation X-ray photoelectron spectrum of C1s presents sp
carbons atoms. The observation of the equally successful growth of graphene on these low-index SiC surfaces makes the GOS technology aviable in the post-Si device developments.

As a part of East Asia Regional NDC Workshop 2014 Mongolia (EARNW2014), the common exercise took place for the purpose of investigation from both of radionuclide and waveform analysis. Each participating NDC analyzed distributed fictitious RN data and real SHI data including non-IMS to find and investigate candidate event. The Japanese NDC-1 (JWA) tried to locate and discriminate the event utilizing local seismic observation data such as NECESSArray (NorthEast China Extended SeiSmic Array) and Korean local data kindly provided by KIGAM. Signals from this event were detected at many stations in such non-IMS network, and it indicated that these local/regional seismic data could contribute largely to estimate more reliable event location and discrimination.
