A planar point set S is an (i, t) set of ghost chimneys if there exist lines H_0, H_1,…,H_<t-1> such that the orthogonal projection of S onto H_j consists of exactly i + j distinct points. We give upper and lower bounds on the maximum value of t in an (i, t) set of ghost chimneys, showing that it is linear in i.

This study examined the relationship between the El Niño Southern Oscillation (ENSO) and atmospheric water isotopes during the wet season over the Maritime Continent. The model data used were obtained by incorporating stable isotopes into atmospheric general circulation and analytical moisture transport models. These models were used to analyze the climatological variables and rainout processes from various water sources that control isotopic variation. The correlation between the simulated stable isotope ratios and ENSO varied between –0.31 and 0.75 with stronger correlation over most of the Maritime Continent (|r|› 0.36, corresponding to the 95 % significance level) except Java. Generally, during La Niña years, the isotopic ratio in water vapor and precipitation is lighter than during El Niño years by about 2 ‰. It was suggested that anomalous water vapor flux, precipitable water, and precipitation, but not evaporation, are responsible for isotopic variation. Furthermore, it was revealed that water vapor flux is convergent (divergent) during La Niña (El Niño) years, which suggests that the strengthened (weakened) Walker Circulation increases (reduces) precipitation and results in lighter (heavier) atmospheric water isotopes. The relationship between isotopes and precipitation, or the so-called "amount effect," is evident over the most of the Maritime Continent. Analysis of moisture transport suggested that rainout processes control isotopic variation. The increase in the quantity water source, expressed in precipitable water, transported from the north and south Maritime Continent during El Niño years does not result in isotopic depletion attributable to the lack of condensation processes. Moreover, the decrease in the quantity of both water source during La Niña years does not result in isotopic enrichment attributable to intensive rainout. An asymmetric ENSO feature was found in this study, evidenced by the similar contributions of water source from the northern Maritime Continent and the Pacific Ocean during both ENSO phases.

国内でも国際的にも交渉の必要性は増大しているが、一般市民にはその教育と学習の機会は少ない。本研究の課題は、交渉の非専門家や一般市民に交渉教育・学習へのアクセスを広げることである。本研究は、交渉の要素を説明する理論とこれらを解説する実例を組み合わせた要素理論表と「要素・理論・ケースサイクル」法によって、以上の課題の解決を図った。本研究によるよりよい交渉実践の普及が、秩序形成と価値創造を促進することが期待される。

Tumor necrosis factor-alpha (TNF-α) is a cytokine that plays an important role in inflammatory process and tumor development. Recent studies demonstrate that triterpene saponins from Vietnamese ginseng are efficient inhibitors of TNF-α. But the interactions between TNF-α and the saponins are still unclear. In this study, molecular docking and molecular dynamics simulations of TNF-α with three different triterpene saponins (majonoside R2, vina-ginsenoside R1 and vina-ginsenoside R2) were performed to evaluate their binding ability. Our results showed that the triterpene saponins have a good binding affinity with protein TNF-α. The saponins were docked to the pore at the top of the “bell” or “cone” shaped TNF-α trimer and the complexes were structurally stable during 100 ns molecular dynamics simulation. The predicted binding sites would help to subsequently investigate the inhibitory mechanism of triterpene saponins.

Functional sites on proteins play an important role in various molecular interactions and reactions between proteins and other molecules. Thus, mutations in functional sites can severely affect the overall phenotype. Progress of genome sequencing projects has yielded a wealth of information on single nucleotide variants (SNVs), especially those with less than 1% minor allele frequency (rare variants). To understand the functional influence of genetic variants at a protein level, we investigated the relationship between SNVs and protein functional sites in terms of minor allele frequency and the structural position of variants. As a result, we observed that SNVs were less abundant at ligand binding sites, which is consistent with a previous study on SNVs and protein interaction sites. Additionally, we found that non-rare variants tended to be located slightly apart from enzyme active sites. Examination of non-rare variants revealed that most of the mutations resulted in moderate changes of the physico-chemical properties of amino acids, suggesting the existence of functional constraints. In conclusion, this study shows that the mapping of genetic variants on protein structures could be a powerful approach to evaluate the functional impact of rare genetic variations.
