Against a background of climate change, Macao is very exposed to sea level rise （SLR） because of its low elevation, small size, and ongoing land reclamation. Therefore, we evaluate sea level changes in Macao, both historical and, especially, possible future scenarios, aiming to provide knowledge and a framework to help accommodate and protect against future SLR. Sea level in Macao is now rising at an accelerated rate： 1.35 mm yr-1 over 1925-2010 and jumping to 4.2 mm yr I over 1970-2010, which outpaces the rise in global mean sea level. In addition, vertical land movement in Macao contributes little to local sea level change. In the future, the rate of SLR in Macao will be about 20% higher than the global average, as a consequence of a greater local warming tendency and strengthened northward winds. Specifically, the sea level is projected to rise 8-12, 22-51 and 35-118 cm by 2020, 2060 and 2100, respectively, depending on the emissions scenario and climate sensitivity. Under the --8.5 W m 2 Representative Concentration Pathway （RCP8.5） scenario the increase in sea level by 2100 will reach 65 118 cm--double that under RCP2.6. Moreover, the SLR will accelerate under RCP6.0 and RCP8.5, while remaining at a moderate and steady rate under RCP4.5 and RCP2.6. The key source of uncertainty stems from the emissions scenario and climate sensitivity, among which the discrepancies in SLR are small during the first half of the 21st century but begin to diverge thereafter.

哈尔滨工业大学学报 1990年第3期22卷 52-61页

作者： zhon.Meide Huang Wenhu Hong Jiarong (School of Astronautics) 哈尔滨工业大学黑龙江哈尔滨

A Newton learning method for a neural network of multilayer perceptrons is proposed in this paper. Furthermore, a hybrid learning method id legitimately developed in combination of the backpropagation method proposed by Rumelhart et al with the Newton learning method. Finally, the hybrid learning algorithm is compared with the backpropagation algorithm by some illustrations, and the results show that this hybrid leaming algorithm bas the characteristics of rapid convergence.

Metastasis-associated protein 1 induces VEGF-C and facilitates lymphangiogenesis in colorectal cancer

引用

World Journal of Gastroenterology 2011年第9期17卷 1219-1226页

作者： Bin Du Zhen-Yu Yang Xue-Yun zhon.Mao Fang Yong-Rong Yan Guo-Long Qi Yun-Long Pan Xu-Long Zhou Department of Pathology MedicalSchool of Jinan University Guangzhou 510632 GuangdongProvince China Division of Medical Inforrnatics Medical Schoolof Jinan University Guangzhou 510632 Guangdong ProvinceChina Department of General Surgery First AffiliatedHospital of Jinan l~lniversity Guangzhou 510632 GuangdongProvince China

AIM:To study the correlation between high metastasisassociated protein 1(MTA1)expression and lymphangiogenesis in colorectal cancer(CRC)and its role in production of vascular endothelial growth factor-C(VEGF-C). METHODS:Impact of high MTA1 and VEGF-C expression levels on disease progression and lymphovasculardensity(LVD,D2-40-immunolabeled)in 81 cases of human CRC was evaluated by immunohistochemistry. VEGF-C mRNA and protein expressions in human LoVo and HCT116 cell lines were detected by real-time polymerase chain reaction and Western blotting,respectively,with a stable expression vector or siRNA. RESULTS:The elevated MTA1 and VEGF-C expression levels were correlated with lymph node metastasis and Dukes stages(P<0.05).Additionally,high MTA1 expression level was correlated with a large tumor size(P< 0.05).A significant correlation was found between MTA1 and VEGF-C protein expressions in tumor cells(r=0.371, P<0.05).Similar to the VEGF-C expression level,high MTA1 expression level was correlated with high LVD in CRC(P<0.05).Furthermore,over-expression of MTA1 significantly enhanced the VEGF-C mRNA and protein expression levels,whereas siRNAs-knocked down MTA1 decreased the VEGF-C expression level. CONCLUSION:MTA1,as a regulator of tumor-associated lymphangiogenesis,promotes lymphangiogenesis in CRC by mediating the VEGF-C expression.

在汉语中,一个主谓结构之前,既可以出现主题化主语和状语,也可以出现非主题句首主语和状语。因此,定语、状语前置后,既可以用做主题化主语和状语,也可以用做非主题句首状语。这时,它们与后续成分之间有一定的句法结构关系,其前置的位移性质当属移位的范畴。否则,前置定语、状语同后续成分之间没有结构关系,其位移的性质则只能属于倒装的范畴。

水价改革是实现水需求管理、进而应对日趋紧张的水资源供需状况的重要手段之一。了解水价改革的效果和相关因素的作用,可为在迅速变化的经济条件下制定合适的水价政策提供支持。为此,本文建立了能反映水价改革影响方式的可计算一般平衡模型(CGE模型),并通过对不同年份CGE模型在不同设定条件下运行结果的对比分析,来评价水价改革效果及其相关因素的作用。北京市的实例应用说明,不同时期水价改革效果明显不同,水价改革具有促进经济发展的潜力,水价政策要着重提高用水部门节水技术水平和对水价的敏感性。
