| 7 | Atmospheric correction for China's coastal water colorremote sensing显示文摘The space satellite programs, such as CZCS/Nimbus - 7, VHRSR/FY - 1, OCFS/ ADEOS and SeaWiFS/SeaStar, have demonstrated and proven that remote sensing is a powerful tool for understanding the spatial and temporal ocean color distribution. In general, there are two main techni-cal keys in the processing ocean color satellite data. They are the atmospheric correction and the inver-sion of water-leaving radiance into water constituents (such as chlorophyll, suspended material and yel low substance) quantitatively. The SeaWiFS (sea-viewing wide field-of-view sensor) atmospheric correc-tion algorithm for China’s coastal waters is discussed. First, the major advantages of SeaWiFS are introduced. Second, in view of the problems of the SeaDAS algorithm applying in China’ s coastal waters, the local atmospheric correction algorithms are discussed and developed. Finally, the advantages of the local algorithms are presented by the compari-son of the results from two different algorithms. | PanDelu, Mao Zhihua 1.

| 8 | Microglia in depression:current perspectives显示文摘Major depressive disorder(MDD)is a prevalent psychiatric disease that involves malfunctions of different cell types in the brain.Accumulating studies started to reveal that microglia,the primary resident immune cells,play an important role in the development and progression of depression.Microglia respond to stress-triggered neuroinflammation,and through the release of proinflammatory cytokines and their metabolic products,microglia may modulate the function of neurons and astrocytes to regulate depression.In this review,we focused on the role of microglia in the etiology of depression.We discussed the dynamic states of microglia;the correlative and causal evidence of microglial abnormalities in depression;possible mechanisms of how microglia sense depression-related stress and modulate depression state;and how antidepressive therapies affect microglia.Understanding the role of microglia in depression may shed light on developing new treatment strategies to fight against this devastating mental illness. | Xiaoning Jia Zhihua Gao Hailan Hu | 2021 | Science China(Life Sciences)2021，64，6： | 25 |

| 10 | In vitro culture and differentiation of rat embryonic midbrain-derived neural stem cells显示文摘BACKGROUND:Midbrain-derived neural stem cells (mNSCs) can differentiate into functional mature dopaminergic neurons. The mNSCs are considered the ideal choice for cell therapy of Parkinson’s disease. OBJECTIVE: To isolate rat embryonic mNSCs and to observe the differentiation characteristics of mNSCs induced by cell growth-promoting factors. DESIGN,TIME AND SETTING: An in vitro cell culture study based on the molecular biology of nerve cells was carried out at the Institute of Clinical Medicine,China-Japan Friendship Hospital (China) from March to November 2007. MATERIALS: Sprague Dawley rats at embryonic day 14 were used in this study. Nestin antibody,β-Ⅲ tubulin antibody,glial fibrillary acidic protein (GFAP) antibody and cyclic nucleotide 3’-phosphohydrolase (CNPase) antibody were provided by Abcam; DMEM/F12 medium and N2 supplement were provided by In-vitrogen; epidermal growth factor (EGF) and fibroblast growth factor-2 (FGF2) were provided by R&D Sys-tems. METHODS: The ventral mesencephalon was dissected from embryonic day 14 rat embryos. By trypsin di-gestion and mechanical separation,the brain tissue was triturated into a fine single-cell suspension. The cells were cultured in 5 mL serum-free medium containing DMEM/F12,1% N2 supplement,20 ng/mL EGF and FGF2. The mNSCs at the third generation were coated with 10 μg/mL polylysine and induced to differenti-ate in the DMEM/F12 supplemented with 1% fetal bovine serum and 1% N2. MAIN OUTCOME MEASURES: The neural spheres of the third passage were identified by nestin im-munofluorescence; at the same time,the cells were induced to differentiate,and the types of differentiated cell were identified by immunofluorescence for βⅢ tubulin,GFAP and CNPase. RESULTS: Seven days after primary culture,a great many neurospheres could be obtained by successive pasage. Immunofluorescence assays showed that the neurospheres were nestin positive,and after differentia-tion,the cells expressed GFAP,CNPase and β-Ⅲ-tubulin. CONCLUSION: Embryonic day 14 rat mNSCs can differentiate into neuron-like cells and glial cells fol-lowing induction by EGF,FGF2 and N2 additive. | Xingli Deng Ruen Liu Zhongtang Feng Jing Guo Wu Wang Deqiang Lei Hongyan Li Zhihua Chen | 2008 | Neural Regeneration Research2008，3，11： | 19 |
| 11 | Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment. | Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show | 2020 | Cell Research2020，30，10： | 19 |
| 12 | Occupant evacuation model based on cellular automata in fire显示文摘By applying the rules set in traffic flow and pedestrian flow models, a basic cellular automata model is presented to simulate occupant evacuation in fire. Some extended models are introduced to study the special phenomena of evacuation from the fire room. The key of the models is the introduction of the danger grade which makes the route choice convenient and reasonable. Fire not only influences the emotional and behavioral characteristics of an individual but also affects his physical constitution, which reduces his maximal possible velocity. The models consider these influence factors by applying a set of simple but effective rules. It is needed to emphasize that all rules are established according to the essential phenomenon in fire evacuation, that is, all the occupants would try to move to the safest place as fast as possible. Some simulation examples are also presented to validate the applicability of the models. | Lizhong Yang Weifeng Fang Rui Huang Zhihua Deng | 2002 | Chinese Science Bulletin2002，47，17： | 16 |

| 14 | Effects of continuously regenerating diesel particulate filters on regulated emissions and number-size distribution of particles emitted from a diesel engine显示文摘The effects of continuously regenerating diesel particulate filter (CRDPF) systems on regulated gaseous emissions, and number-size distribution and mass of particles emanated from a diesel engine have been investigated in this study. Two CRDPF units (CRDPF-1 and CRDPF-2) with different specifications were separately retrofitted to the engine running with European steady-state cycle (ESC). An electrical low pressure impactor (ELPI) was used for particle number-size distribution measurement and mass estimation. The conversion/reduction rate (R CR ) of hydrocarbons (HC) and carbon monoxide (CO) across CRDPF-1 was 83% and 96.3%, respectively. Similarly, the R CR of HC and CO and across CRDPF-2 was 91.8% and 99.1%, respectively. The number concentration of particles and their concentration peaks; nuclei mode, accumulation mode and total particles; and particle mass were highly reduced with the CRDPF units. The nuclei mode particles at downstream of CRDPF-1 and CRDPF-2 decreased by 99.9% to 100% and 97.8% to 99.8% respectively; and the particle mass reduced by 73% to 92.2% and 35.3% to 72.4%, respectively, depending on the engine conditions. In addition, nuclei mode particles increased with the increasing of engine speed due to the heterogeneous nucleation initiated by the higher exhaust temperature, while accumulation mode particles were higher at higher loads due to the decrease in the air-to-fuel ratio (A/F) at higher loads. | Zhihua Liu Asad Naeem Shah Yunshan Ge Yan Ding, Jianwei Tan Lei Jiang Linxiao Yu Wei Zhao Chu Wang Tao Zeng | 2011 | Journal of Environmental Sciences2011，23，5： | 15 |

| 16 | Family control,institutional environment and cash dividend policy:Evidence from China显示文摘Using a sample of 1486 Chinese A-share listed companies for the period 2004-2008,this study empirically tests the impact of family control,institutional environment and their interaction on the cash dividend policy of listed companies.Our results indicate that(1)family firms have a lower cash dividend payout ratio and propensity to pay dividends than non-family firms;(2) a favorable regional institutional environment has a significant positive impact on the cash dividend payout ratio and propensity to pay dividends of listed companies;and(3) the impact of the regional institutional environment on cash dividends is stronger in family firms than in non-family firms.Somewhat surprisingly,we find that controlling family shareholders in China may intensify Agency Problem Ⅰ(the owner-manager conflict) rather than Agency Problem Ⅱ(the controlling shareholder-minority shareholder conflict),and thus have a significant negative impact on cash dividend policy.In contrast,a favorable regional institutional environment plays a positive corporate governance role in mitigating Agency Problem 1 and encouraging family firms to pay cash dividends. | Zhihua Wei Shinong Wu Changqing Li Wei Chen | 2011 | China Journal of Accounting Research2011，，Z1： | 15 |

| 18 | Performance deterioration modeling and optimal preventive maintenance strategy under scheduled servicing subject to mission time显示文摘Servicing is applied periodically in practice with the aim of restoring the system state and prolonging the lifetime. It is generally seen as an imperfect maintenance action which has a chief influence on the maintenance strategy. In order to model the maintenance effect of servicing, this study analyzes the deterioration characteristics of system under scheduled servicing. And then the deterioration model is established from the failure mechanism by compound Poisson process. On the basis of the system damage value and failure mechanism, the failure rate refresh factor is proposed to describe the maintenance effect of servicing. A maintenance strategy is developed which combines the benefits of scheduled servicing and preventive maintenance. Then the optimization model is given to determine the optimal servicing period and preventive maintenance time, with an objective to minimize the system expected life-cycle cost per unit time and a constraint on system survival probability for the duration of mission time. Subject to mission time, it can control the ability of accomplishing the mission at any time so as to ensure the high dependability. An example of water pump rotor relating to scheduled servicing is introduced to illustrate the failure rate refresh factor and the proposed maintenance strategy. Compared with traditional methods, the numerical results show that the failure rate refresh factor can describe the maintenance effect of servicing more intuitively and objectively. It also demonstrates that this maintenance strategy can prolong the lifetime, reduce the total lifetime maintenance cost and guarantee the dependability of system. | Li Dawei Zhang Zhihua Zhong Qianghui Zhai Yali | 2014 | Chinese Journal of Aeronautics2014，27，4： | 14 |

| 20 | Preparation and anisotropic properties of textured structural ceramics: A review显示文摘Ceramics are usually composed of randomly oriented grains and intergranular phases, so their properties are the statistical average along each direction and show isotropy corresponding to the uniform microstructures. Some methods have been developed to achieve directional grain arrangement and preferred orientation growth during ceramic preparation, and then textured ceramics with anisotropic properties are obtained. Texture microstructures give particular properties to ceramics along specific directions, which can effectively expand their application fields. In this review, typical texturing techniques suitable for ceramic materials, such as hot working, magnetic alignment, and templated grain growth(TGG), are discussed. Several typical textured structural ceramics including α-Al2O3 and related nacre bioinspired ceramics, Si3N4 and SiAlON, h-BN, MB2 matrix ultra-high temperature ceramics, MAX phases and their anisotropic properties are presented. | Zhuo ZHANG Xiaoming DUAN Baofu QIU Zhihua YANG Delong CAI Peigang HE Dechang JIA Yu ZHOU | 2019 | Journal of Advanced Ceramics2019，8，3： | 14 |
