| 1 | Cellular automata pedestrian movement model considering human behavior显示文摘The pedestrian movement is more complex than vehicular flow for the reason that people are more flexible and intelligent than car. Without the limit of 搇anes?pedestrian movement is loose and free. Furthermore, they are easily affected by other walkers as well as the environ-ment around. In this paper some special technique is intro-duced considering human behavior to make the rules more reasonable. By simulating the two-dimension pedestrian movement, the phase transition phenomena of pedestrian movement, including the up walkers moving from the bottom to the upper boundary and the right walkers moving from the left to the right boundary, are presented. Studying on the effect of the system size on the critical density shows that the critical density is independent of the system size in the scope studied in this paper. | YANG Lizhong, FANG Weifeng, LI Jian, HUANG Rui & FAN Weicheng State Key Laboratory of Fire Science, University of Science and Tech-nology of China, Hefei 230026, China Correspondence should be addressed to Yang Lizhong (e-mail:zxd@ustc. edu.cn) | 2003 | Chinese Science Bulletin2003，48，16： | 16 |
| 2 | Cold acclimation improves photosynthesis by regulating the ascorbate–glutathione cycle in chloroplasts of Kandelia obovata显示文摘As the most northerly mangrove species in China, Kandelia obovata may undergo extreme cold event stress. Enhancing the cold tolerance of this species is crucial to its successful afforestation. This study aimed to determine the resistance of K. obovata seedlings to low temperature stress by cold acclimation and to explain the mechanisms for alleviating cold injury. To understand these mechanisms, seedlings that were acclimatized and not acclimatized were exposed to 5℃/- 2℃(day/night)for 48 h.Results showed that low temperature stress reduced leaf photosynthesis of non-acclimatized seedlings by inducing oxidative stress and structural damage to chloroplasts. These phenomena were shown by increasing levels of malondialdehyde (MDA), O2-and H2O2, as well as decreasing enzyme activities in the ascorbate–glutathione (AsA-GSH) cycle. However, cold-acclimatized seedlings had improved photosynthetic rates and efficiency of photosystem II (PSII) under low temperature stress. Compared with non-acclimatized seedlings, leaves of coldacclimatized seedlings under low temperature stress for 48 h exhibited higher anti-oxidative enzyme activities, lower levels of O2^- and H2O2, less damage to chloroplast structure, and removed 33.7% of MDA at low temperature stress for 48 h. The data indicate that cold acclimation enhances photosynthetic capacity by effectively regulating activation in the PSII electron transport and the AsA–GSH cycle to scavenge excess ROS in chloroplasts, while the latter is more important. | Weicheng Liu Chunfang Zheng Jinong Chen Jianbiao Qiu Zhixing Huang Qi Wang Yong Ye | 2019 | Journal of Forestry Research2019，30，3： | 11 |
| 3 | A systematic review of metabolomic profiling of gastric cancer and esophageal cancer显示文摘Objective:Upper gastrointestinal(UGI)cancers,predominantly gastric cancer(GC)and esophageal cancer(EC),are malignant tumor types with high morbidity and mortality rates.Accumulating studies have focused on metabolomic profiling of UGI cancers in recent years.In this systematic review,we have provided a collective summary of previous findings on metabolites and metabolomic profiling associated with GC and EC.Methods:A systematic search of three databases(Embase,PubMed,and Web of Science)for molecular epidemiologic studies on the metabolomic profiles of GC and EC was conducted.The Newcastle–Ottawa Scale(NOS)was used to assess the quality of the included articles.Results:A total of 52 original studies were included for review.A number of metabolites were differentially distributed between GC and EC cases and non-cases,including those involved in glycolysis,anaerobic respiration,tricarboxylic acid cycle,and protein and lipid metabolism.Lactic acid,glucose,citrate,and fumaric acid were among the most frequently reported metabolites of cellular respiration while glutamine,glutamate,and valine were among the most commonly reported amino acids.The lipid metabolites identified previously included saturated and unsaturated free fatty acids,aldehydes,and ketones.However,the key findings across studies to date have been inconsistent,potentially due to limited sample sizes and the majority being hospital-based case-control analyses lacking an independent replication group.Conclusions:Studies on metabolomics have thus far provided insights into etiological factors and biomarkers for UGI cancers,supporting the potential of applying metabolomic profiling in cancer prevention and management efforts. | Sha Huang Yang Guo Zhexuan Li Yang Zhang Tong Zhou Weicheng You Kaifeng Pan Wenqing Li | 2020 | Cancer Biology & Medicine2020，17，1： | 11 |
