Izumi, T.,Ibi, A.,Nakaoka, K.,Taneda, T.,Yoshida, T.,Takagi, Y.,Nakamura, T.,Machi, T.,Katayama, K.,Sakai, N.,Yoshizumi, M.,Koizumi, T.,Kimura, K.,Kato, T.,Kiss, T.,Shiohara, Y. The Korea Institute of Applied Superconductivity a 2014 한국초전도저온공학회논문지 Vol.16 No.2
The five-year national project in Japan for R&D of coated conductors and applications, named as the Materials and Power Applications of Coated Conductors (M-PACC) project, was finished at the end of FY2013. The project consists of four sub-themes as cable, transformer, SMES and coated conductors. In the theme of coated conductors, the fabrication process had been developed to satisfy the requirements from the applications such as in-field $I_c$ performance, low AC loss in the long tapes etc. Through the project, the remarkable progress was achieved as follows; a high in-field minimum $I_c$ value over 54A/cm-width under 3T at 77K was realized in a 200m long EuBCO tape with artificial pinning centers of $BaHfO_3$ by the pulsed laser deposition (PLD) technique on the IBAD template. On the other hand, the AC loss reduction was confirmed in the tapes fabricated by both PLD and the metal organic deposition (MOD) techniques by scribing 100m tapes into 10-filamments. Additionally, the mechanism of the delamination phenomenon was systematically investigated and the strength was improved by eliminating the origins of the weak points in the films. Through the development, all targeted goals were accomplished and the several results were appreciated as a world champion data.

The recent updates of the North Ecliptic Pole deep (0.5~deg$^2$, NEP-Deep)multi-wavelength survey covering from X-ray to radio-wave is presented. The NEP-Deep provides us with several thousands of 15~$\mu$m or 18~$\mu$mselected galaxies, which is the largest sample ever made at thesewavelengths. A continuous filter coverage in the mid-infrared wavelength(7, 9, 11, 15, 18, and 24~$\mu$m) is unique and vital to diagnose thecontributions from starbursts and AGNs in the galaxies out to $z$=2. The new goal of the project is to resolve the nature of the cosmic star formationhistory at the violent epoch (e.g. $z$=1--2), and to find a clue to understandits decline from $z$=1 to presentuniverse by utilizing the unique power of the multiwavelength survey. The progressin this context is briefly mentioned.

An overview of the North Ecliptic Pole (NEP) deep multi-wavelength survey covering from X-ray to radio wavelengths is presented. The main science objective of this multi-wavelength project is to unveil the star-formation and AGN activities obscured by dust in the violent epoch of the Universe (z=0.5-2), when the star formation and black-hole evolution activities were much stronger than the present. The NEP deep survey with AKARI/IRC consists of two survey projects: shallow wide (8.2 sq. deg, NEP-Wide) and the deep one (0.6 sq. deg, NEP-Deep). The NEP-Deep provides us with a $15{\mu}m$ or $18{\mu}m$ selected sample of several thousands of galaxies, the largest sample ever made at these wavelengths. A continuous filter coverage at mid-IR wavelengths (7, 9, 11, 15, 18, and $24{\mu}m$) is unique and vital to diagnose the contribution from starbursts and AGNs in the galaxies at the violent epoch. The recent updates of the ancillary data are also provided: optical/near-IR magnitudes (Subaru, CFHT), X-ray (Chandra), FUV/NUV (GALEX), radio (WSRT, GMRT), optical spectra (Keck/DEIMOS etc.), Subaru/FMOS, Herschel/SPIRE, and JCMT/SCUBA-2.

The AKARI NEP Deep Field Survey is an international multiwavelength survey over 0.4 deg$^2$ of the sky. This is the deepest survey made by the InfraRed Camera (IRC) of the infrared astronomical satellite AKARI with 9 filters continuously covering the 2-25 μm range, including three filters in the Spitzer gap between the IRAC and MIPS coverages. This enabled us to make sensitive MIR detection of AGN candidates at z ~ 1, based on hot dust emission in the AGN torus. It is also efficient in detecting highly obscured Compton-thick AGN population. In this article, we report the first results of X-ray observations on this field. The field was covered by 15 overlapping Chandra ACIS-I observations with a total exposure of ~ 300 ks, detecting $\approx 450$ X-ray sources. We utilize rest-frame stacking analysis of the MIR AGN candidates that are not detected individually. Our preliminary analysis shows a marginal detection of the rest-frame stacked Fe K$\alpha$ line from our strong Compton-thick candidates.
The AKARI NEP-Deep survey: a mid-infrared source catalogue
Takagi, T.,Matsuhara, H.,Goto, T.,Hanami, H.,Im, M.,Imai, K.,Ishigaki, T.,Lee, H. M.,Lee, M. G.,Malkan, M.,Ohyama, Y.,Oyabu, S.,Pearson, C. P.,Serjeant, S.,Wada, T.,White, G. J. Springer-Verlag 2012 Astronomy and astrophysics Vol.537 No.-
<P>We present a new catalogue of mid-IR sources using the AKARI NEP-Deep survey. The InfraRed Camera (IRC) onboard AKARI has a comprehensive mid-IR wavelength coverage with 9 photometric bands at 2–24?µm. We utilized all of these bands to cover a nearly circular area adjacent to the north ecliptic pole (NEP). We designed the catalogue to include most of sources detected in 7, 9, 11, 15 and 18?µm bands, and found 7284 sources in a 0.67?deg<SUP>2</SUP> area. From our simulations, we estimate that the catalogue is~80 per cent complete to 200µJy at 15–18µm, and ~10 per cent of sources are missed, owing to source blending. Star-galaxy separation is conducted using only AKARI photometry, as a result of which 10 per cent of catalogued sources are found to be stars. The number counts at 11, 15, 18, and 24µm are presented for both stars and galaxies. A drastic increase in the source density is found in between 11 and 15µm at the flux level of~300micro;Jy. This is likely due to the redshifted PAH emission at 8µm, given our rough estimate of redshifts from an AKARI colour–colour plot. Along with the mid-IR source catalogue, we present optical-NIR photometry for sources falling inside a Subaru/Sprime-cam image covering part of the AKARI NEP-Deep field, which is deep enough to detect most of AKARI mid-IR sources, and useful to study optical characteristics of a complete mid-IR source sample.</P>
A MULTI-WAVELENGTH STUDY OF PAH-SELECTED STARBURST GALAXIES
Takagi, T.,Matsuhara, H.,Wada, T.,Ohyama, Y.,Oyabu, S. The Korean Astronomical Society 2012 天文學論叢 Vol.27 No.4
Using extensive mid-IR datasets from AKARI, i.e. 9-band photometry covering the wavelength range from $2{\mu}m$ to $24{\mu}m$ and the unbiased spectroscopic survey for sources with $S_{\nu}$($9{\mu}m$)>0.3 mJy, we study starburst galaxies specifically at the redshift of z ~ 0.5, whose mid-IR spectra are clearly dominated by the PAH emission features. PAH-selected galaxies, selected with extremely red mid-IR colour due to PAHs, have high rest-frame PAH-to-stellar luminosity ratios, comparable to those in the most active regions in nearby starburst galaxies. Thus, they seem to have active starburst regions spreading over the whole body. Furthermore, some of PAH-selected galaxies are found to have peculiar rest-frame 11-to-$8{\mu}m$ flux ratios, which is systematically smaller than nearby starburst/AGN spectral templates. This may indicate a systematic difference in the physical condition of ISM between nearby and distant starburst galaxies.
Generation of monoclonal antibodies specific for ORF68 of koi herpesvirus
Aoki, T.,Takano, T.,Unajak, S.,Takagi, M.,Kim, Y.R.,Park, S.B.,Kondo, H.,Hirono, I.,Saito-Taki, T.,Hikima, J.i.,Jung, T.S. Pergamon Press 2011 Comparative immunology, microbiology and infectiou Vol.34 No.3
Outbreaks of koi herpesvirus (KHV) infection in carp are still a serious problem worldwide. KHV is closely related to other two cyprinid herpesviruses, pox herpesvirus (CHV) and haematopoietic necrosis herpesvirus (CyHV-2) in goldfish. In this study, two major KHV antigenic proteins (ORF62 and ORF68) were identified by immunoscreening using a KHV-specific polyclonal antibody, and then monoclonal antibodies were generated for immunodiagnostic studies. After screening hybridoma cells, one mAb against ORF68 (mAb-7C6) was obtained but no mAbs against ORF62. mAb-7C6 specifically reacted with a lysate of KHV-infected koi fin cells (KF-1 cells) but not with lysates of CHV- or CyHV-2-infected KF-1 cells in an immuno-blotting analysis. Similar results were shown in the following tests: (1) a indirect fluorescent antibody test using infected KF-1 cells and (2) an immunohistochemical investigation by fast red stain (infected liver) or FITC detection (infected spleen). These results suggested that mAb-7C6 specifically reacts with KHV ORF68 protein.
