A change of toroidal current by controlling the magnetic configuration has been observed in Heliotron J. The effect of the magnetic configuration on the neoclassical bootstrap current has been theoretically investigated for Heliotron J. It is found that the bumpy field component (B04) plays an important role in changing both the value and the direction of the bootstrap current in Heliotron J. The bootstrap current density is reversed at the small minor radius first, and then the net bootstrap current changes its direction from a positive value to a negative value as B04 decreases.

The measurement of D, CII and CIII line spectral profiles and the CD band spectrum from the vicinity of a test limiter surface is performed in Heliotron J test limiter experiments. With deep insertion of the limiter, there is a localized intense region of the D, CII and CIII line intensity in the limiter surface, and the CD band spectrum is observed at this region. It is considered that the deuterium ion flux and heat load concentrate at this region and enhance carbon impurity generation.r_che
Dust transport from northeastern China inferred from carbon isotopes of atmospheric dust carbonate
Chen, B.,Kitagawa, H.,Jie, D.,Hu, K.,Lim, J. Pergamon Press ; Elsevier [distribution] 2008 Atmospheric environment Vol.42 No.19
We made carbon and oxygen isotope analyses on the carbonates in atmospheric dust samples (hereafter, atmospheric dust carbonates) over the saline land of Songnen Plain (SSL) and at Changchun, 50km eastward from the east margin of SSL, as well as in the surface soil samples in SSL. The atmospheric dust carbonates from SSL and Changchun had similar carbon isotopic composition as the soil carbonates from SSL, while showing a distinct difference with the atmospheric dust carbonates in the northwestern Chinese deserts. The atmospheric dust carbonates for two of the three heavy dust storms at Changchun had a similar carbon isotopic composition as those in SSL. The dust emission from SSL makes a significant contribution to the dust storms in the downwind area. Carbon isotopic composition of the atmospheric dust carbonates should be a useful indicator for inferring the dust source. We have also noted a depleting trend of <SUP>13</SUP>C of atmospheric dust carbonates from west to east over northern China. The incorporating process of dust generated in areas under the pathway of the Asian dust transport might be investigated from the carbon isotopic composition in atmospheric dust carbonates.
Managing Frequent Updates in R-Trees for Update-Intensive Applications
Moon-Bae Song,Kitagawa, H. IEEE 2009 IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERIN Vol.21 No.11
<P>Managing frequent updates is greatly important in many update-intensive applications, such as location-aware services, sensor networks, and stream databases. In this paper, we present an R-tree-based index structure (called R<SUP>sb</SUP>-tree, <I>R</I>-tree with semibulk loading) for efficiently managing frequent updates from massive moving objects. The concept of semibulk loading is exploiting a small in-memory buffer to defer, buffer, and group the incoming updates and bulk-insert these updates simultaneously. With a reasonable memory overhead (typically only 1 percent of the whole data set), the proposed approach far outperforms the previous works in terms of update and query performance as well in a realistic environment. In order to further increase buffer hit ratio for the proposed approach, a new page-replacement policy that exploits the level of buffered node is proposed. Furthermore, we introduce the concept of deferring threshold ratio (dtr) that simply enables deferring CPU- and I/O-intensive operations such as node splits and removals. Extensive experimental evaluation reveals that the proposed approach is far more efficient than previous approaches for managing frequent updates under various settings.</P>
