| 2 | Immune‑Ageing Evaluation of Peripheral T and NK Lymphocyte Subsets in Chinese Healthy Adults显示文摘Ageing is often accompanied with a decline in immune system function,resulting in immune ageing.Numerous studies have focussed on the changes in different lymphocyte subsets in diseases and immunosenescence.The change in immune phenotype is a key indication of the diseased or healthy status.However,the changes in lymphocyte number and phenotype brought about by ageing have not been comprehensively analysed.Here,we analysed T and natural killer(NK)cell subsets,the phenotype and cell differentiation states in 43,096 healthy individuals,aged 20–88 years,without known diseases.Thirty-six immune parameters were analysed and the reference ranges of these subsets were established in different age groups divided into 5-year intervals.The data were subjected to random forest machine learning for immune-ageing modelling and confirmed using the neural network analysis.Our initial analysis and machine modelling prediction showed that na.ve T cells decreased with ageing,whereas central memory T cells(Tcm)and effector memory T cells(Tem)increased cluster of differentiation(CD)28-associated T cells.This is the largest study to investigate the correlation between age and immune cell function in a Chinese population,and provides insightful differences,suggesting that healthy adults might be considerably influenced by age and sex.The age of a person's immune system might be different from their chronological age.Our immune-ageing modelling study is one of the largest studies to provide insights into‘immune-age’rather than‘biological-age’.Through machine learning,we identified immune factors influencing the most through ageing and built a model for immune-ageing prediction.Our research not only reveals the impact of age on immune parameter differences within the Chinese population,but also provides new insights for monitoring and preventing some diseases in clinical practice. | Zhenghu Jia Zhiyao Ren Dongmei Ye Jiawei Li Yan Xu Hui Liu Ziyu Meng Chengmao Yang Xiaqi Chen Xinru Mao Xueli Luo Zhe Yang Lina Ma Anyi Deng Yafang Li Bingyu Han Junping Wei Chongcheng Huang Zheng Xiang Guobing Chen Peiling Li Juan Ouyang Peisong Chen Oscar Junhong Luo Yifang Gao Zhinan Yin | 2023 | Phenomics2023，3，4： | 1 |
| 3 | MAX phase forming mechanism of M-Al-C(M=Ti,V,Cr)coatings:In-situ X-ray diffraction and first-principle calculations显示文摘The interesting hybrid properties of ceramics and metals induced by unique nano-laminated structures make the M_(n+1)AX n(MAX)phase attractive as a potential protective coating for vital structural compo-nents in harsh systems.However,an extremely narrow phase-forming region makes it difficult to prepare MAX phase coatings with high purity,which is required to obtain coatings with high-temperature anti-oxidation capabilities.This work describes the dependence of the phase evolution in deposited M-Al-C(M=Ti,V,Cr)coatings as a function on temperature using in-situ X-ray diffraction analysis.Compared to V_(2)AlC and Cr_(2)AlC MAX phase coatings,the Ti_(2)AlC coating displayed a higher phase-forming tempera-ture accompanied by a lack of any intermediate phases before the appearance of the Ti_(2)AlC MAX phase.The results of the first-principle calculations correlated with the experience in which Ti_(2)AlC exhibited the largest formation energy and density of states.The effect of the phase compositions of these three MAX phase coatings on mechanical properties were also investigated using ex-situ Vickers and nano-indenter tests,demonstrating the improved mechanical properties with good stability at high temperatures.These findings provide a deeper understanding of the phase-forming mechanism of MAX phase coatings to guide the preparation of high-purity MAX phase coatings and the optimization of MAX phase coatings with expected intermediate phases such as Cr_(2)C,V_(2)C etc.,as well as their application as protective coat-ings in temperature-related harsh environments. | Jianghuai Yuan Zhenyu Wang Guanshui Ma Xiaojing Bai Yong Li Xiaoying Cheng Peiling Ke Aiying Wang | 2023 | Journal of Materials Science & Technology2023，，12： | 0 |
| 4 | Seismic Sequence Characteristics and Precursory Anomalies of the M_S6.3 and M_S6.4 Da Qaidam Earthquakes in 2008~2009显示文摘In this paper,the seismogenic structures of the Da Qaidam strong earthquakes are preliminarily discussed by using the regional seismotectonic data and focal mechanism solutions. Analysis is done on the temporal and spatial distribution characteristics of the two strong earthquake sequences in Da Qaidam in combination with the sequence distribution characteristics of the M6. 6 earthquake of 2003 and the five strong earthquakes of about M5. 0 in 2004 in Delingha. At the same time,the regional characteristics of the historical seismic activity are also investigated. Preliminary analysis is done on the influence of the two M8. 0 earthquakes in the past 10 years on this region. Precursory anomalies and their characteristics are discussed in combination with the analysis of the precursor observation data of Qinghai Province. | Ma Yuhu Liu Wenbang Wang Peiling Yang Xiaoxia Chen Yuhua | 2013 | Earthquake Research in China2013，27，2： | 0 |
