为了研究九州—帕劳洋脊(KPR)俯冲部分与同震破裂扩展、地震活动性和浅部甚低频地震的关系,对南海海槽西部俯冲带日向滩地区进行了三维地震层析成像。结合岸上和近海记录的主动源和被动源地震数据,成像了从该海槽轴附近到海岸地区的深部板块。我们的结果表明,俯冲的九州—帕劳洋脊为西北—东南向的低速带,向下扩展到约30km的深度。在这个深度,我们认为俯冲的九州—帕劳洋脊与板块分离,成为上覆大陆板块的底座。由于过去大地震的同震滑动地区没有延伸到俯冲的九州—帕劳洋脊,我们认为九州—帕劳洋脊可能阻碍了破裂的扩展。俯冲的九州—帕劳洋脊的内部在很宽的深度上分布有活跃的板内地震活动。浅部甚低频地震在俯冲的九州—帕劳洋脊上部连续发生,而在俯冲的九州—帕劳洋脊的东北部却是间歇地出现。因此,俯冲的九州—帕劳洋脊看来是这个地区同震破裂扩展和地震现象的一个重要因素。

PURPOSE: If it were possible to identify.the features of primary.colorectal carcinoma that were associated with liver metastasis, these features could be used as predictors of liver metastasis. METHODS: From January.1995 to December 1997, 648 consecutive cases of colorectal carcinoma were recorded at the Department of Surgery. National Cancer Center Hospital, Toky., Japan. We evaluated clinicopathologic and immunohistochemical factors (age, gender, tumor location, gross ty.e, size, histologic ty.e, dedifferentiation of invasive front, depth of invasion, ly.phatic invasion, venous invasion, ly.ph-node metastasis, and expression of CD10, MUC2, and human gastric mucin) in 505 of these patients who had undergone resection of T2/T3/T4 colorectal carcinomas to clarify.the correlation between these factors and liver metastasis. RESULTS: Liver metastases, including unresectable, were detected in 122 patients (24 percent), all of whom had been followed for at least five y.ars. Univariate analy.is revealed that liver metastasis was significantly.associated with tumor size, histologic ty.e, dedifferentiation of invasive front, depth of invasion, ly.phatic invasion, venous invasion, ly.ph-node metastasis, and CD10 expression. Multivariate analy.is revealed that invasion deeper than the subserosa, venous invasion, ly.ph-node metastasis, and CD10 expression were significantly.associated with liver metastases. CONCLUSIONS: CD10 expression in colorectal carcinoma is a good predictor of liver metastasis.

PURPOSE: Risk factors for ly.ph node metastasis in patients with nonpedunculated submucosal invasive colorectal carcinoma remain to be characterized. This study.examines the relationship between ly.ph node metastasis and clinicopathologic factors in nonpedunculated submucosal invasive colorectal carcinoma. METHODS: The study.cohort comprised 155 patients who had undergone surgical treatment for nonpedunculated submucosal invasive colorectal carcinoma. The clinicopathologic factors investigated included gender, age, tumor location, macroscopic ty.e, tumor size, histologic ty.e and grade, intramucosal growth pattern, ly.phatic invasion, venous invasion, degree of focal dedifferentiation at the submucosal invasive front, status of the remaining muscularis mucosa, and the depth and width of submucosal invasion. RESULTS: Ly.ph node metastases were found in 19 patients (12.3 percent). Univariate analy.is showed that ly.phatic invasion, focal dedifferentiation at the submucosal invasive front, status of the remaining muscularis mucosa, and depth of submucosal invasion all had a significant influence on ly.ph node metastasis. Multivariate analy.is showed ly.phatic invasion (P = 0.014) and high-grade focal dedifferentiation at the submucosal invasive front (P = 0.049) to be independent factors predicting ly.ph node metastasis. No ly.ph node metastasis was found in tumors with a depth of submucosal invasion of y.phatic invasion and high-grade focal dedifferentiation at the submucosal invasive front are important predictors of ly.ph node metastasis in patients with nonpedunculated submucosal invasive colorectal carcinoma. Depth of submucosal invasion can be used as an identify.ng marker for patients who do not require subsequent surgery.after endoscopic resection.

In this study. genetic poly.orphisms, NQO1 C609T, GSTM1 positive/null, and GSTT1 positive/null, were examined with reference to cervical cancer risk in a population- based incident case- control study.in Japanese. The cases comprised 131 cervical cancer patients: 87 cases with squamous cell carcinoma (SCC) and 44 with adenocarcinoma (ADC) or adenosquamous carcinoma (ADSC). Controls were sampled from 320 healthy.women who underwent a health checkup. The cervical cancer risk was substantially.elevated with smoking for all cases, SCC cases, and ADC/ADSC cases (OR = 4.50, 95% CI = 2.48- 8.17, P y.. The frequency.of the NQO1 609TT genoty.e, reported to be associated with null enzy.e activity. was higher in individuals with all cases and SCC than in the healthy.controls (OR = 1.97, 95% CI = 1.06- 3.66, P = 0.032; and OR = 2.42, 95% CI = 1.21- 4.82, P = 0.012; respectively., but not in ADC/ADSC cases. Analy.is of poly.orphisms for GSTM1 and GSTT1 showed no significant differences between cervical cancer patients and controls. In stratification analy.is, significant elevated risk of all cases and SCC was associated with the NQO1 609TT genoty.e among nonsmokers (OR = 2.15, 95% CI = 1.08- 4.30, P = 0.030; and OR = 2.83, 95% CI = 1.21- 6.31, P = 0.011; respectively., but not smokers. No gene- gene interaction was observed in our case subjects. This is the first report that the NQO1 gene might be important in relation to the risk of squamous cell carcinoma of the cervix.

In the Large Helical Device （LHD）, two different divertor configurations, i.e. helical divertor （HD） and local island divertor （LID）, are utilized to control the edge plasma. The HD with two X-points is an intrinsic divertor for heliotron devices, accompanied with a relatively.thick ergodic lay.r outside the confinement region. Edge and divertor plasma behavior from low density.to high density.regimes is presented, referring to the divertor detachment. The effect of the ergodic lay.r on the edge transport is also discussed. On the other hand, the LID is an advanced divertor concept which realizes a high pumping efficiency.by.the combination of an externally.induced magnetic island and a closed pumping sy.tem. Experimental results to confirm the fundamental divertor performance of the LID are presented.

为了降低汽车的CO_2排放,发动机越来越有必要釆用高效燃烧和小型化增压技术。然而,采用这些技术后排气温度和催化器性能也随之降低。因此,有必要开发低温活性催化剂来降低排放。研究了Pd/CeO_2材料,其在低温下可以氧化CO。为了提高催化剂活性,研究了在CeO_2材料中添加一些元素。研究发现,添加Zn可以使CO起燃温度降低60℃,这主要是因为添加Zn促进了CeO_2材料表面的活性氧释放。然而,重复发动机排气试验表明,净化性能有所降低。碳酸盐抑制了CeO_2材料表面活性氧的释放,从而降低了催化剂的净化性能。为了提高催化剂的性能,添加了具有很强CO_2吸附能力的高碱性Ba。即使在进行重复发动机排气试验后,这种改性的Ba/Zn/CeO_2材料净化性能也没有降低。接下来,在传统催化器上使用LA4循环试验对应用Ba/Zn/CeO_2材料的车辆排放效果进行评估。结果表明,相对于没有添加剂的催化剂,排放改善了约10%。新开发的Ba/Zn/CeO_2材料已经应用在2016年型的量产催化器上。

Green-emitting strontium thiogallate doped with Eu(SrGaS:Eu)thin film phosphors were prepared by.the multi- source deposition technique using two electron beam evaporation sources and a thermal annealing at higher than 800℃ or both low temperature annealing and laser annealing using KrF excimer laser in atmosphere of 1% HS diluted with Ar. The film annealed at 850℃ showed a luminance of around 2.7×10cd/m under excitation with 5kV and 60μA/cm. Moreover,In this study.preparation of green-emitting SrGaS:Eu thin film phosphors by.thermal annealing at tempera- tures lower than 600° was also tried with an assist with a laser annealing technique with 248nm due to KrF excimer laser. It was shown that the film annealed at 500℃ consisted of SrGS single phase and showed about 2000cd/m under excita- tion with 4 kV,60μA/cm.These results indicate that the process of the laser annealing is useful for the realization of FEDs with high performance.

The formation and control of a room-temperature magnetic order in two- dimensional （2D） materials is a challenging quest for the advent of innovative magnetic- and spintronic-based technologies. To date, edge magnetism in 2D materials has been experimentally.observed in hy.rogen （H）-terminated graphene nanoribbons （GNRs） and graphene nanomeshes （GNMs）, but the measured magnetization remains far too small to allow envisioning practical applications. Herein, we report experimental evidences of large room-temperature edge ferromagnetism （FM） obtained from oxy.en （O）-terminated zigzag pore edges of few-lay.r black phosphorus （P） nanomeshes （BPNMs）. The magnetization values per unit area are -100 times larger than those reported for H-terminated GNMs, while the magnetism is absent for H-terminated BPNMs. The magnetization measurements and the first-principles simulations suggest that the origin of such a magnetic order could stem from ferromagnetic spin coupling between edge P with O atoms, resulting in a strong spin localization at the edge valence band, and from uniform oxidation of full pore edges over a large area and interlay.r spin interaction. Our findings pave the way.for realizing high-efficiency.2D flexible magnetic and spintronic devices without the use of rare magnetic elements.
