| 1 | Prognostic significance of expression of cyclooxygenase-2 and vascular endothelial growth factor in human gastric carcinoma显示文摘AIM: To investigate the role of cyclooxygenase-2(COX-2)and vascular endothelial growth factor (VEGF) in the development of gastric carcinoma and correlation between expression of COX-2 and VEGF and clinicopathologic features in tissues from patients with gastric carcinoma.METHODS: 281 patients with gastric carcinoma who underwent surgical resection between 1990 and 1999 at the First Affiliated Hospital, Anhui Medical University, PRC, were followed up. Expression of COX-2 and VEGF was investigated retrospectively in 232 gastric carcinoma tissues and 60noncancerous specimens by using immunohistochemistry.RESULTS: The 5-year survival rates of early gastric carcinoma (EGC) and advanced gastric carcinoma (AGC) were 93.4 %and 59.0 %, respectively. Survival time was highly correlated with lymph node metastasis, vascular invasion, depth of invasion and treatment with chemotherapy. Compared with paired noncancerous tissues, expression of COX-2 and VEGF and microvessel density (MVD) value in carcinoma tissue were significantly higher. The MVD value was much higher in COX-2-positive group and VEGF-positive group than that in COX-2-negative group and VEGF-negative group.Expression of COX-2 and VEGF, as well as MVD value were highly correlated with lymph node metastasis and vascular invasion. The 5-year survival rate of patients with expression of COX-2 or VEGF was significantly lower than that of patients without COX-2 or VEGF expression. Multivariate analysis revealed that VEGF overexpression, lymph node metastasis,COX-2 overexpression, depth of invasion and vascular invasion were all independent prognostic factors of gastric carcinoma.CONCLUSION: Overexpression of COX-2 and VEGF in patients with gastric carcinoma can enhance the possibility of invasion and metastasis, implicating a poor prognosis.They may serve as the fairly good prognostic factors to indicate biologic behaviors of gastric carcinoma. | Hai Shi Jian-Ming Xu Nai-Zhong Hu Hui-Jun Xie Department of Gastroenterology,the First Affiliated Hospital,Anhui Medical University,Hefei 23022,Anhui Province,China | 2003 | World Journal of Gastroenterology2003，9，7： | 64 |
| 2 | Sorption of Eu(Ⅲ) on GMZ bentonite in the absence/presence of humic acid studied by batch and XAFS techniques显示文摘Bentonite has been extensively studied because of its strong sorption ability and low permeability.In this work,the Na-bentonite from Gaomiaozi County (China) has been characterized by XRD,FTIR and acid-base titration.The sorption of Eu(III) on Na-bentonite in the absence/presence of humic acid (HA) was studied at T = 25 ± 2 °C and in 0.01 mol/L NaClO4 solution.The effects of pH,HA,contact time and initial Eu(III) concentrations were also investigated.The results indicate that the sorption of Eu(III) on Na-bentonite was dependent on pH values.The presence of HA had little effect on Eu(III) sorption at low pH values,but decreased Eu(III) sorption at high pH values.X-ray absorption fine structure spectroscopy (XAFS) was applied to characterize the local structural environment of the adsorbed Eu(III) on bare Na-bentonite and HA-bentonite hybrids.The re- sults indicate that Eu(III) was bound to O atoms at a distance of about 2.39 at pH 4.15.The results are crucial for the evalua- tion of the sorption and migration of other trivalent lanthanides and actinides in bentonite as backfill materials. | HU Jun1,2,XIE Zhi3,HE Bo3,SHENG GuoDong1,CHEN ChangLun1,LI JiaXing1,CHEN YiXue2 & WANG XiangKe1 1Key Laboratory of Novel Thin Film Solar Cells Institute of Plasma Physics,Chinese Academy of Sciences,Hefei 230031,China 2School of Nuclear Science and Engineering,North China Electric Power University,Beijing 102206,China 3National Synchrotron Radiation Laboratory,University of Science & Technology of China,Hefei 230029,China | 2010 | Science China Chemistry2010，53，6： | 12 |
| 3 | Algorithms for k-fault tolerant power assignments in wireless sensor networks显示文摘This paper addresses fault-tolerant many-to-many routing power assignments in heterogeneous wire-less sensor networks.We introduce the k-fault tolerant power assignments problem with the objective of assigning each sensor node transmission power such that(1) any pairwise sensor node is k-vertex connected and(2) the to-tal power consumption is minimized.We propose three solutions for this problem:two centralized algorithms,a greedy algorithm and an O(√n/ε)-approximation algorithm,and an h-hop distributed and localized algorithm.Related theorems and proofs are presented to prove the correctness of our approaches.Furthermore,simulation and experiment results are presented to verify the efficiency of our approaches. | LIU Li 1,2,LI Lian 1,3 & HU Bin 1,4 1 School of Information Science and Engineering,Lanzhou University,Lanzhou 730000,China 2 LRI,Univ Paris-sud and CNRS,Orsay F-91405,France 3 School of Computer and Information,Hefei University of Technology,Hefei 230009,China 4 Department of Computing,Birmingham City University,Galton Building,Perry Barr,Birmingham B42 2SU,UK | 2010 | Science China(Information Sciences)2010，53，12： | 5 |
| 4 | Packet Cache-Forward Method Based on Improved Bayesian Outlier Detection for Mobile Handover in Satellite Networks显示文摘In this paper, we propose a Packet Cache-Forward(PCF) method based on improved Bayesian outlier detection to eliminate out-of-order packets caused by transmission path drastically degradation during handover events in the moving satellite networks, for improving the performance of TCP. The proposed method uses an access node satellite to cache all received packets in a short time when handover occurs and forward them out in order. To calculate the cache time accurately, this paper establishes the Bayesian based mixture model for detecting delay outliers of the entire handover scheme. In view of the outliers' misjudgment, an updated classification threshold and the sliding window has been suggested to correct category collections and model parameters for the purpose of quickly identifying exact compensation delay in the varied network load statuses. Simulation shows that, comparing to average processing delay detection method, the average accuracy rate was scaled up by about 4.0%, and there is about 5.5% cut in error rate in the meantime. It also behaves well even though testing with big dataset. Benefiting from the advantage of the proposed scheme in terms of performance, comparing to conventional independent handover and network controlled synchronizedhandover in simulated LEO satellite networks, the proposed independent handover with PCF eliminates packet out-of-order issue to get better improvement on congestion window. Eventually the average delay decreases more than 70% and TCP performance has improved more than 300%. | Hefei Hu Dongming Yuan Mingxia Liao Yuan'an Liu | 2016 | China Communications2016，13，6： | 4 |

| 6 | Encounter probability analysis of typhoon and plum rain in the Taihu Lake Basin显示文摘It is of great significance to study the encounter possibility of typhoon and plum rain in the Taihu Lake Basin in order to adjust the schemes of design storm and utilize flood resource and make the decision of real-time scheduling for flood control in the Basin. Based upon the existing research findings of description of encounter phenomena of typhoon and plum rain, the initial time of typhoon affecting the Taihu Lake Basin, the start time of plum rain season and the end time of plum rain season were selected as the characteristic indices of typhoon and plum rain, respectively. According to their synchronous data from 1954 to 2009, the distribution functions of the above-mentioned three random variables were identified and a formula expressing the encounter possibility of typhoon and plum rain was derived. In view of the complexity and solution of this formula, joint distribution functions of typhoon and plum rain were constructed by the use of Gumbel Copula function on the basis of the adaptability comparison among three functions (Gumbel Copula, Clayton Copula and Frank Copula) in Archimedean functions. For the characteristics of the formula with the joint distribution functions based on Gumbel Copula function, two methods, i.e., numerical integration and Monte Carlo simulation, were selected to solve the encounter probability, and the validity of the computed results was analyzed finally. | HU SiYi1,2, WANG ZongZhi1, WANG YinTang1, WU HaoYun3, JIN JuLiang4, FENG XiaoChong1 & CHENG Liang1 1 State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Nanjing Hydraulic Research Institute, Nanjing 210029, China 2 Ministry of Water Resources, Beijing 100053, China 3 Taihu Basin Authority, Ministry of Water Resources, Shanghai 200434, China 4 School of Civil Engineering, Hefei University of Technology, Hefei 230009, China | 2010 | Science China(Technological Sciences)2010，53，12： | 3 |
| 7 | Stable isotopic analysis on sus bones from the Wanfabozi site, Tonghua, Jilin显示文摘In order to study the sus diets and explore the possibility to distinguish domestic pig from wild boar through dietary analysis, stable carbon and nitrogen isotopes of 28 pig bones from archaeological site of Wanfabozi in Tonghua City, Jilin Province were analyzed. The δ 13C and δ 15N values of uncontaminated bones show that the overall pigs in the site were generally herbivores and ate mainly C3 plants. Significant difference of δ15N values was observed between wild boar and domestic pigs, which may result from the higher consumption of animal protein in domestic pigs other than from that in wild boar, possibly from human leftover or waste,. The dietary difference between wild boar and domestic pigs has great potential to differentiate wild boar and domestic pigs in the early stage of pig domestication. | GUAN Li1, HU YaoWu2, TANG zhuoWei3, YANG YiMin2, DONG Yu1, CUI YaPing4 & WANG ChangSui2 1 Department of History of Science & Technology and Archaeometry University of Science and Technology of China, Hefei 230026, China 2 Department of Scientific History and Archaeometry School of the Humanities, Graduate University of Chinese Academy of Sci- ences, Beijing 100049, China 3 Laboratory of Environment Archaeology, Research Center for Chinese Frontier Archaeology Jilin University Changchun 130012, China 4 Museum of the West Han Dynasty Mausoleum of the Nanyue King, Guangzhou 510040, China | 2007 | Chinese Science Bulletin2007，52，24： | 3 |

| 16 | ON THE OPTIMIZATION OF VLSI ALLOCATION IN HIGH-LEVEL SYNTHESIS显示文摘Allocation is one of main tasks in the high-level synthesis. It includes module , functional unit allocation, storage allocation and interconnection allocation. This paper models the allocation problem as cluster analysis and applies a new algorithm, neighbor state transition (NST) algorithm, for cluster optimization. It is proved that the algorithm produces an asymptotically global optimal solution with the upper bound on the cost function (1 + O(1/n)2-ε)F*, When F' is the cost of the optimum solution, n is the problem size and e is a positive parameter arbitrarily close to zero. The numerical examples show that the NST algorithm produces better results compared to the other known methods. | He Zhongli Zhou Dian Hu Qingsheng Zhuang Zhenquan(Department of Electronic Engineering, University of Science and Technology of China, Hefei 230026) (The University of North Carolina at Charlotte) | 2000 | Journal of Electronics(China)2000，17，3： | 1 |

| 20 | A NUMERICAL STUDY ON VORTEX RINGS WITH SWIRL显示文摘A finite difference scheme in cylindrical coordinates was used to study the three dimensional (3D) motion of a vortex ring with swirl and the passage interaction between two vortex rings. For the 3D evolution of a single thin ring, the azimuthal perturbation modes grow linearly in the early stage. According to their growth rates, two bands of growing waves, which correspond to the first and the second radial mode respectively, can be observed. The result is similar to the prediction of short wave instability theory for swirl free vortex rings. For the passage process between two rings, results show that the azimuthal velocity is in inverse proportion to radius while the azimuthal vorticity is in proportion to radius during the interaction. | Hu Guo hui, Sun De jun, Yin Xie yuan Department of Modern Mechanics, University of Science and Technology of China, Hefei 230026 , China | 2001 | Journal of Hydrodynamics2001，13，2： | 0 |
