Characteristics and performances of an interferometric Doppler imager installed at the 188 cm telescope of Okayama Observatory

F. X. Schmider Julien Dejonghe T. Guillot Masahiro Ikoma P. Boumier

We describe the performances of a novel Doppler imager, aimed to detect acoustic oscillations and atmospheric dynamics at the surface of giant planets of the Solar System in the frame of the JOVIAL (Jovian Oscillations detection by Velocity Imaging At several Longitudes) project. The first JOVIAL instrument was installed on the 188cm telescope at Okayama branch of National Astronomical Observatory of Japan (NAOJ) in April 2019. This instrument is a part of a ground based network of three identical instruments installed on telescopes around the world for continuous observations. First observations of Jupiter with the JOVIAL instrument were achieved in June 2019. We describe the instrument principle, its design and the set-up at Okayama observatory, as well as the performances reached during the first observing run. We finally provide plans for future observations with the network.

Part-time job satisfaction of international students in Japan:

The Japanese journal of psychology (2019)

Lin Yan Takashi Horiuchi

This study was designed to examine factors that improve job satisfaction of international students studying in Japan when doing part-time jobs, based on sub-theories of the Self-Determination Theory (SDT). A hypothetical model based on the organismic integration theory and basic psychological needs theory, which are sub-theories of the SDT, were developed and examined through covariance structure analysis. The main results were as follows: (a) the need for relatedness and the need for competence, which are basic psychological needs, directly improve job satisfaction; (b) autonomous motivation is increased, and higher job satisfaction is obtained by satisfying the three psychological needs; (c) positive effect of the need for relatedness on the need for competence and positive effect of the need for competence on the need for autonomy were observed, suggesting the importance of satisfying the need for relatedness in part-time employment. The psychological processes affecting the job satisfaction of international students studying in Japan when doing part-time jobs is discussed based on the above results.

Kiso Supernova Survey (KISS): Survey strategy

Publications of the Astronomical Society of Japan (2014)

Tomoki Morokuma Nozomu Tominaga Masaomi Tanaka K. Mori Emiko Matsumoto

Abstract The Kiso Supernova Survey (KISS) is a high-cadence optical wide-field supernova (SN) survey. The primary goal of the survey is to catch the very early light of a SN, during the shock breakout phase. Detection of SN shock breakouts combined with multi-band photometry obtained with other facilities would provide detailed physical information on the progenitor stars of SNe. The survey is performed using a 2 $_{.}^{\circ}$2 × 2 $_{.}^{\circ}$2 field-of-view instrument on the 1.05-m Kiso Schmidt telescope, the Kiso Wide Field Camera (KWFC). We take a 3-min exposure in g-band once every hour in our survey, reaching magnitude g ∼ 20–21. About 100 nights of telescope time per year have been spent on the survey since 2012 April. The number of the shock breakout detections is estimated to be of the order of 1 during our three-year project. This paper summarizes the KISS project including the KWFC observing setup, the survey strategy, the data reduction system, and CBET-reported SNe discovered so far by KISS.

Influence of survival processing and delay on recollection and familiarity in recognition

The Japanese journal of psychology (2015)

Tetsuya Munetsugu Takashi Horiuchi

The survival processing effect is a robust memory phenomenon of memory whereby encouraging participants to judge words for relevance to a survival situation produces better recall than other processing tasks such as semantic or self-reference tasks (Nairne, Thompson, & Pandeirada, 2007). The present study separated memory performance into recollection and familiarity, and estimated the contribution of these two factors to the survival processing effect as adaptive memory by using a recognition test based on the dual-process signal detection model. This study also examined the long-term persistence of the effect by delay manipulation (immediate, after a week, after five weeks) of the recognition test. Under delayed conditions (after a week and five weeks), survival processing advantage occurred on recollection, but semantic processing had no effect. In contrast, for familiarity, there was no significant difference between survival and semantic processing. These findings suggest that the survival processing effect mainly relies on recollection.

Genetic analyses of an amber mutation in Escherichia coli K-12, affecting deoxyribonucleic acid ligase and viability

Journal of Bacteriology (1975)

Takashi Sato Takashi Horiuchi Takako Nagata

Genetic analyses of an Escherichia coli K-12 mutant possessing the amber mutation lig-321 were carried out. This mutant is defective in deoxyribonucleic acid (DNA) ligase and conditionally lethal. We constructed strains harboring an F'lig+ or F'lig-321 plasmid. Genetic complementation analyses were done by using these plasmids and by constructing a lig-4/F'lig-321 merodiploid. It was shown that lig-321 does not complement lig-4, unless the former is suppressed by an amber suppressor. The same was found to be the case between lig-321 and lig-ts7. Transductional mapping of lig-321, by a four-factor cross, revealed that lig-321 is very closely linked to lig-4. The frequency of recombinants between the two alleles was not unreasonable for assuming that they arose by intragenic recombination. The lig-4 and lig-ts7 alleles are known to reside in the structural gene for DNA ligase, in which lig-321 may also be located.

RECENT RESULTS FROM THE TOKYO AXION HELIOSCOPE EXPERIMENT

Y. Inoue T. Namba S. Moriyama M. Minowa Yuko Takasu

We have searched for axions which could have been produced in the solar core using an axion helioscope with a 2.3m-long 4T superconducting magnet. Axion mass region up to m_a=0.26eV was newly explored by introducing dispersion-matching gas. Preliminary analysis sets a limit on axion-photon coupling constant to be less than (6.4--9.6)e-10 GeV^{-1} (95%CL) for this mass region from the absence of the axion signal. This is more stringent than the limit inferred from the solar age consideration and also more stringent than the recent helioseismological bound.

Determination of Glycarbylamide Residues in Chicken Tissues by HPLC with Post-Column Reaction

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi) (2006)

Yasuharu Mizuno Takashi Horiuchi Tatsuro Sekiya Noriko Tazima Masako Maeda

A newly developed HPLC method for determination of glycarbylamide (GB) in chicken liver was applied to other tissues (muscle, fat and kidney). The recoveries of GB in muscle, fat and kidney were 87.2% (CV 0.5), 91.3% (CV 4.7), 79.7% (CV 1.0), respectively. The detection limit of GB was 0.01 ppm. GB concentrations were determined by this method in tissues (muscle, fat, liver and kidney) from chickens sacrificed 5 days after oral administration of GB mixed in feed at 60 mg/kg of feed for 7 days. GB was not detected in these chicken tissues.
