| 1 | Grey matter volume abnormalities in patients with bipolar I depressive disorder and unipolar depressive disorder:a voxelbased morphometry study显示文摘Bipolar disorder and unipolar depressive disorder(UD) may be different in brain structure. In the present study,we performed voxel-based morphometry(VBM) to quantify the grey matter volumes in 23 patients with bipolar I depressive disorder(BP1) and 23 patients with UD,and 23 age-,gender-,and educationmatched healthy controls(HCs) using magnetic resonance imaging. We found that compared with the HC and UD groups,the BP1 group showed reduced grey matter volumes in the right inferior frontal gyrus and middle cingulate gyrus,while the UD group showed reduced volume in the right inferior frontal gyrus compared to HCs. In addition,correlation analyses revealed that the grey matter volumes of these regions were negatively correlated with the Hamilton depression rating scores. Taken together,the results of our study suggest that decreased grey matter volume of the right inferior frontal gyrus is a common abnormality in BP1 and UD,and decreasedgrey matter volume in the right middle cingulate gyrus may be specifi c to BP1. | Yi Cai Jun Liu Li Zhang Mei Liao Yan Zhang Lifeng Wang Hongjun Peng Zhong He Zexuan Li Weihui Li Shaojia Lu Yuqiang Ding Lingjiang Li | 2015 | Neuroscience Bulletin2015，31，1： | 11 |
| 2 | A Memetic Algorithm Based Feature Weighting for Metabolomics Data Classification显示文摘A metaheuristic chain based memetic algorithm namely MCMA is proposed for the classification of metabolomics data. MCMA regards both global evolution and local search as equivalent elemental metaheuristics,and searches with a chain of metaheuristics performed alternatively on the target problem. A hidden Markov model based scheduling mechanism is employed in MCMA for the selection of metaheuristics. By using MCMA for optimizing the linkage weight vector, a feature weighting algorithm for metabolomics data is formed to identify relevant metabolite features and reveal their exact relationships with the given physiological states. An extreme learning machine based classifier is utilized in predicting the physiological states according to the weighted metabolite features. Experimental results on real metabolomics data of clinical liver transplantation demonstrate that the proposed feature weighting and classification method obtains better performance than the other compared algorithms. | ZHOU Jiarui ZHU Zexuan JI Zhen | 2014 | Chinese Journal of Electronics2014，23，4： | 5 |
| 3 | Green hydrogen:A promising way to the carbon-free society显示文摘With increasing importance attached by the international community to global climate change and the pressing energy revolution,hydrogen energy,as a clean,efficient energy carrier,can serve as an important support for the establishment of a sustainable society.The United States and countries in Europe have already formulated relevant policies and plans for the use and development of hydrogen energy.While in China,aided by the“30·60”goal,the development of the hydrogen energy,production,transmission,and storage industries is steadily advancing.This article comprehensively considers the new energy revolution and the relevant plans of various countries,focuses on the principles,development status and research hot spots,and summarizes the different green hydrogen production technologies and paths.In addition,based on its assessment of current difficulties and bottlenecks in the production of green hydrogen and the overall global hydrogen energy development status,this article discusses the development of green hydrogen technologies. | Ying Zhou Ruiying Li Zexuan Lv Jian Liu Hongjun Zhou Chunming Xu | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 5 |

| 5 | Impact of immunization programs on 11 childhood vaccine-preventable diseases in China: 1950–2018显示文摘To evaluate the achievements of China’s immunization program between 1950 and 2018,we chose 11 vaccine-preventable diseases(VPDs)as representative notifiable diseases and used annual surveillance data obtained between 1950 and 2018 to derive disease incidence and mortality trends.Quasi-Poisson and polynomial regression models were used to estimate the impacts of specific vaccine programs,and life-table methods were used to calculate the loss of life expectancy,years of life lost,and loss of working years.The total notification number for the 11 VPDs was 211,866,000 from 1950 to 2018.The greatest number occurred in 1959,with a total incidence of 1,723 per million persons.From 1978 to 2018,a substantial decline was observed in the incidence of major infectious diseases.The incidence of pertussis fell 98%from 126.35 to 1.58 per million,and the incidences of measles,meningococcal meningitis,and Japanese encephalitis fell 99%,99%,and 98%,respectively.The regression models showed that most of the 11 diseases exhibited dramatic declines in morbidity after their integration into the Expanded Program on Immunization(EPI),while varicella and paratyphoid fever,which were not integrated into the EPI,showed increased morbidity.From 1978 to 2018,the total life expectancy for the 11 VPDs increased by 0.79 years,and similar results were obtained for different age groups.China has had great success in controlling VPDs in recent decades,and improving vaccination coverage is a key aspect of controlling VPDs in China. | Jinhua Pan Yesheng Wang Lingsheng Cao Ying Wang Qi Zhao Shenglan Tang Wenfeng Gong Lei Guo Zhixi Liu Zexuan Wen Bo Zheng Weibing Wang | 2021 | The Innovation2021，2，2： | 2 |

| 16 | Roles of hydroxyl and oxygen vacancy of CeO_(2)·xH_(2)O in Pd-catalyzed ethanol electro-oxidation显示文摘In the field of noble metal-catalyzed alcohol electro-oxidation reaction(AOR),huge attention is paid on the composition,size,facet,and structure of the metals,while the support engineering should also be emphasized.CeO_(2)has been widely used as a unique support in AOR,primarily due to its abundant oxygen vacancies(O_(v)).Herein,we report CeO_(2)·xH_(2)O nanoparticles with both massive hydroxyl groups(OH)and O_(v)remarkably enhance the catalytic activity and stability of Pd toward ethanol oxidation reaction(EOR).The CO striping experiments and density functional theory(DFT)calculations suggest that OH and O_(v)on CeO_(2)·xH_(2)O surface bring about a large downshift of Pd d-band center and a significant weakening of CO absorption on Pd.Moreover,OH and O_(v)also play synergic roles in the removal of toxic intermediates.Consequently,the important roles of OH and O_(v)of CeO_(2)·xH_(2)O are confirmed in Pd-catalyzed EOR.The facile CeO_(2)·xH_(2)O-enhanced strategy can contribute to the catalyst design for other energy conversion reactions. | Zhenyu Li Jiefei Li Zexuan Zheng Kunhong Jiang Tianrun Zheng Dongmin Wang Hang Wei Zhiming Shi Xiaotian Li Haibin Chu | 2022 | Science China Chemistry2022，65，5： | 1 |

| 20 | Fractional-order Sparse Representation for Image Denoising显示文摘Sparse representation models have been shown promising results for image denoising. However, conventional sparse representation-based models cannot obtain satisfactory estimations for sparse coefficients and the dictionary. To address this weakness, in this paper, we propose a novel fractional-order sparse representation(FSR) model. Specifically, we cluster the image patches into K groups, and calculate the singular values for each clean/noisy patch pair in the wavelet domain. Then the uniform fractional-order parameters are learned for each cluster.Then a novel fractional-order sample space is constructed using adaptive fractional-order parameters in the wavelet domain to obtain more accurate sparse coefficients and dictionary for image denoising. Extensive experimental results show that the proposed model outperforms state-of-the-art sparse representation-based models and the block-matching and 3D filtering algorithm in terms of denoising performance and the computational efficiency. | Leilei Geng Zexuan Ji Yunhao Yuan Yilong Yin | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，2： | 1 |
