Satoshi Kubo,Akinori Sakaguch,Takashi Takimoto 제어로봇시스템학회 2014 제어로봇시스템학회 국제학술대회 논문집 Vol.2014 No.10
This paper deals with a flying observation which are consist of a helium gas balloon and a tilt rotor helicopter. The helium gas balloon can make flight for a long time. The tilt rotor helicopter is stable in the wind and increase buoyant force. The observation system with the helium gas balloon and the tilt rotor gets the best of both worlds. In general, helium gas is released from a balloon in every aerial photographing work. Moreover most aerial photographers with the balloon give up a flight in the wind of 5 m/s or greater. However proposed device does not need to release helium gas. Additionally, the flying observation device in the proposed can make a flight in the winds of 5 m/s or greater.

Lung cancer is the most common cause of death from cancer worldwide, and its incidence is increasing in East Asian and Western countries. To identify genetic factors that modify the risk of lung adenocarcinoma, we conducted a genome-wide association study in a Japanese cohort, with replication in two independent studies in Japanese and Korean individuals, in a total of 2,098 lung adenocarcinoma cases and 11,048 controls. The combined analyses identified two susceptibility loci for lung adenocarcinoma: TERT (rs2736100, combined P = 2.91 ? 10<SUP>??11</SUP>, odds ratio (OR) = 1.27) and TP63 (rs10937405, combined P = 7.26 ? 10<SUP>??12</SUP>, OR = 1.31). Fine mapping of the region containing TP63 showed that a SNP (rs4488809) in intron 1 of TP63 showed the most significant association. Our results suggest that genetic variation in TP63 may influence susceptibility to lung adenocarcinoma in East Asian populations.

The characteristic muonic X-ray measuring system for low pressure gas sample was constructed to investigate the initial process of muonic atom formation. Low background characteristic muonic X-ray spectra were obtained for neon (1.0 bar) and nitrogen mono-oxide samples (0.99 bar) by muon irradiation with 19 MeV/c. The deviation of characteristic muonic X-ray intensity patterns both for muonic nitrogen and oxygen atoms in nitrogen mono-oxide sample between our low pressure experiment and the previous high pressure experiment was found. Muon capture probability was also determined and compared with the previous work and empirical estimations.

Ambient aerosol particles at forest and suburban sites in western Japan were analyzed for imidazole compounds, such as 4 (5)-Methylimidazole (4-MI), 1-ethylimidazole (1-EI), 2-ethylimidazole (2-EI), and imidazole-2-carboxaldehyde (IC). The aerosols were collected on quartz fiber filters and extracted by the solid phase extraction method. The extract was analyzed by HPLC/Q-TOF-MS using an ion-pairing agent. The concentration of 4-MI in winter was higher than those in summer at the forest site; its concentration was highest among the analyzed imidazoles. The concentration of 4-MI in the suburban site was several times higher than the forest site. Anthropogenic activities, such as vehicle emissions, are considered to be the major source of 4-MI in this region.

This paper explores a fundamental study of acquiring the users`` KANSEI information regarding the recognition of shape models. Since there are many differences such as background differences and knowledge differences among users, they will produce different evaluations based on their KANSEI even when an identical shape model is presented. Cluster analysis is proved to be available for catching a group tendency and for constructing a mapping relation between a description of the shape model and the HANSEl database. In order to investigate an analogical relation and a mutual influence in our consciousness, first, we made a questionnaire that asked subjects to represent images having different colors and shape cones by using 4 pairs of adjectives (KANSEI words). Next, based on the cluster analysis of the questionnaire using a fuzzy set theory, we proposed a hypothesis showing how the analogical relation and the mutual influence work in our mind while viewing the shape models. Furthermore, how the properties of KANSEI depend on their descriptions was also investigated by virtue of the cluster analysis. This work will be valuable to construct a personal KANSEI database regarding the Shape Model Processing System.

<P>The O<SUB>2</SUB> and NO reactivity of a Cr(II) complex bearing a 12-membered tetraazamacrocyclic <I>N</I>-tetramethylated cyclam (TMC) ligand, [Cr<SUP>II</SUP>(12-TMC)(Cl)]<SUP>+</SUP> (<B>1</B>), and the NO reactivity of its peroxo derivative, [Cr<SUP>IV</SUP>(12-TMC)(O<SUB>2</SUB>)(Cl)]<SUP>+</SUP> (<B>2</B>), are described. By contrast to the previously reported Cr(III)–superoxo complex, [Cr<SUP>III</SUP>(14-TMC)(O<SUB>2</SUB>)(Cl)]<SUP>+</SUP>, the Cr(IV)–peroxo complex <B>2</B> is formed in the reaction of <B>1</B> and O<SUB>2</SUB>. Full spectroscopic and X-ray analysis revealed that <B>2</B> possesses side-on η<SUP>2</SUP>-peroxo ligation. The quantitative reaction of <B>2</B> with NO affords a reduction in Cr oxidation state, producing a Cr(III)–nitrato complex, [Cr<SUP>III</SUP>(12-TMC)(NO<SUB>3</SUB>)(Cl)]<SUP>+</SUP> (<B>3</B>). The latter is suggested to form via a Cr(III)–peroxynitrite intermediate. [Cr<SUP>II</SUP>(12-TMC)(NO)(Cl)]<SUP>+</SUP> (<B>4</B>), a Cr(II)–nitrosyl complex derived from <B>1</B> and NO, could also be synthesized; however, it does not react with O<SUB>2</SUB>.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2012/jacsat.2012.134.issue-37/ja307384e/production/images/medium/ja-2012-07384e_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja307384e'>ACS Electronic Supporting Info</A></P>

Kim, Sun Hee,Park, Hyejin,Seo, Mi Sook,Kubo, Minoru,Ogura, Takashi,Klajn, Jan,Gryko, Daniel T.,Valentine, Joan Selverstone,Nam, Wonwoo American Chemical Society 2010 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.132 No.40
<P>Mn(IV)-peroxo and Mn(V)-oxo corroles were synthesized and characterized with various spectroscopic techniques. The intermediates were directly used in O−O bond cleavage and formation reactions. Upon addition of proton to the Mn(IV)-peroxo corrole, the formation of the Mn(V)-oxo corrole was observed. Interestingly, addition of base to the Mn(V)-oxo corrole afforded the formation of the Mn(IV)-peroxo corrole. Thus, we were able to report the first example of reversible O−O bond cleavage and formation reactions using in situ generated Mn(IV)-peroxo and Mn(V)-oxo corroles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2010/jacsat.2010.132.issue-40/ja1066465/production/images/medium/ja-2010-066465_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja1066465'>ACS Electronic Supporting Info</A></P>

<P>Metal−dioxygen adducts are key intermediates detected in the catalytic cycles of dioxygen activation by metalloenzymes and biomimetic compounds. In this study, mononuclear cobalt(III)−peroxo complexes bearing tetraazamacrocyclic ligands, [Co(12-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> and [Co(13-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP>, were synthesized by reacting [Co(12-TMC)(CH<SUB>3</SUB>CN)]<SUP>2+</SUP> and [Co(13-TMC)(CH<SUB>3</SUB>CN)]<SUP>2+</SUP>, respectively, with H<SUB>2</SUB>O<SUB>2</SUB> in the presence of triethylamine. The mononuclear cobalt(III)−peroxo intermediates were isolated and characterized by various spectroscopic techniques and X-ray crystallography, and the structural and spectroscopic characterization demonstrated unambiguously that the peroxo ligand is bound in a side-on η<SUP>2</SUP> fashion. The O−O bond stretching frequency of [Co(12-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> and [Co(13-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> was determined to be 902 cm<SUP>−1</SUP> by resonance Raman spectroscopy. The structural properties of the CoO<SUB>2</SUB> core in both complexes are nearly identical; the O−O bond distances of [Co(12-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> and [Co(13-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> were 1.4389(17) Å and 1.438(6) Å, respectively. The cobalt(III)−peroxo complexes showed reactivities in the oxidation of aldehydes and O<SUB>2</SUB>-transfer reactions. In the aldehyde oxidation reactions, the nucleophilic reactivity of the cobalt−peroxo complexes was significantly dependent on the ring size of the macrocyclic ligands, with the reactivity of [Co(13-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP> > [Co(12-TMC)(O<SUB>2</SUB>)]<SUP>+</SUP>. In the O<SUB>2</SUB>-transfer reactions, the cobalt(III)−peroxo complexes transferred the bound peroxo group to a manganese(II) complex, affording the corresponding cobalt(II) and manganese(III)−peroxo complexes. The reactivity of the cobalt−peroxo complexes in O<SUB>2</SUB>-transfer was also significantly dependent on the ring size of tetraazamacrocycles, and the reactivity order in the O<SUB>2</SUB>-transfer reactions was the same as that observed in the aldehyde oxidation reactions.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2010/jacsat.2010.132.issue-47/ja107177m/production/images/medium/ja-2010-07177m_0009.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja107177m'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja107177m'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja107177m'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja107177m'>ACS Electronic Supporting Info</A></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja107177m'>ACS Electronic Supporting Info</A></P>
