1Changes in Extreme Maximum Temperature Events and Population Exposure in China under Global Warming Scenarios of 1.5 and 2.0°C: Analysis Using the Regional Climate Model COSMO-CLM显示文摘We used daily maximum temperature data(1986–2100) from the COSMO-CLM(COnsortium for Small-scale MOdeling in CLimate Mode) regional climate model and the population statistics for China in 2010 to determine the frequency, intensity, coverage, and population exposure of extreme maximum temperature events(EMTEs) with the intensity–area–duration method. Between 1986 and 2005(reference period), the frequency, intensity, and coverage of EMTEs are 1330–1680 times yr^(–1), 31.4–33.3°C, and 1.76–3.88 million km^2, respectively. The center of the most severe EMTEs is located in central China and 179.5–392.8 million people are exposed to EMTEs annually. Relative to 1986–2005, the frequency, intensity, and coverage of EMTEs increase by 1.13–6.84, 0.32–1.50, and15.98%–30.68%, respectively, under 1.5°C warming; under 2.0°C warming, the increases are 1.73–12.48, 0.64–2.76,and 31.96%–50.00%, respectively. It is possible that both the intensity and coverage of future EMTEs could exceed the most severe EMTEs currently observed. Two new centers of EMTEs are projected to develop under 1.5°C warming, one in North China and the other in Southwest China. Under 2.0°C warming, a fourth EMTE center is projected to develop in Northwest China. Under 1.5 and 2.0°C warming, population exposure is projected to increase by23.2%–39.2% and 26.6%–48%, respectively. From a regional perspective, population exposure is expected to increase most rapidly in Southwest China. A greater proportion of the population in North, Northeast, and Northwest China will be exposed to EMTEs under 2.0°C warming. The results show that a warming world will lead to increases in the intensity, frequency, and coverage of EMTEs. Warming of 2.0°C will lead to both more severe EMTEs and the exposure of more people to EMTEs. Given the probability of the increased occurrence of more severe EMTEs than in the past, it is vitally important to China that the global temperature increase is limited within 1.5°C.Mingjin ZHAN Xiucang LI Hemin SUN Jianqing ZHAI Tong JIANG Yanjun WANG 2018Journal of Meteorological Research2018,32,1:11
2Meta-analysis of Traditional Chinese Medicine in treating functional dyspepsia of liver-stomach disharmony syndrome显示文摘OBJECTIVE:To systematically assess the clinical effectiveness of traditional Chinese medicine(TCM) in the treatment of functional dyspepsia(FD) of liver-stomachdisharmonysyndromebymeta-analysis.METHODS:Random controlled trials(RCTs) were retrieved from databases,including Pubmed,China national knowledge infrastructure,Wanfang Data,VIP Information,and the Cochrane Library.Trials were selected according to inclusion criteria.The effects of traditional Chinese medicine(TCM) versus prokinetic agents in the treatment of functional dyspepsia(FD) of liver-stomach disharmony syndrome were compared by meta-analysis.RevMan 5.0.24 was used for data analysis.The effective rate was assessed by odds ratios(ORs),and 95% confidence intervals(CIs) were calculated.The cure rate was analyzed by the Peto OR.Simple statistical analysis was chosen to assess the frequency of prescribed Chinese herbs in treating this syndrome.RESULTS:Thirteen trials were included,involving 1153 patients,and these were of poor methodological quality.Twelve studies mentioned the effective rate and cure rate.TCM therapy showed a better clinical effect rate compared with that with prokinetic agents [OR:3.2,95% CI(2.27,4.51)].The TCM group also had a better cure rate than that in the group of prokinetic agents [Peto OR:2.26,95% CI(1.61,3.18)].With regard to the frequency of Chinese herbs used in these 13 trials,Baishao(Radix Paeoniae),Chaihu(Radix Bupleuri),and Gancao(Radix Glycyrrhizae) were mostly prescribed,followed by Xiangfu(Rhizoma Cyperi),Zhishi(Fructus Aurantii Immaturus),Zhiqiao(Fructus Aurantii),Foshou(Citrus medica var.sarcodactylis),and Chenpi(Pericarpium Citri Reticulatae).No serious adverse effects were reported.CONCLUSION:TCM therapy shows a superior effective rate and cure rate compared with those in prokinetic agents in the treatment of FD of liver-stomach disharmony syndrome.However,further strictly designed RCTs are required because of the poor quality of included trials.Chuijie Wang Mingjin Zhu Wei Xia Wei Jiang Yan Li 2012Journal of Traditional Chinese Medicine2012,32,4:9

4Optimization of working parameters for puddling and flatting machine in paddy field显示文摘In order to improve the soil preparation quality,a wide puddling and flatting machine for paddy field was designed with the functionality of tillage,soil crushing,puddling,burying stubble and flatting in one-time operation,which can be equipped on tractors with high power.This study focused on the design and analysis of key components of the machine including puddling equipment,flat shovel and balance structure.Optimal results with field trials and response surface analysis showed that the machine can operate optimally when the working speed,puddling depth and angle of flat shovel were 1.05 km/h,16 cm and 31.30°,respectively.The surface flatness standard deviation was 3.7 cm,and slurry degree was 1.03 g/cm3.Field validation test results were consistent with the optimal parameters,which was able to meet agronomic requirements of mechanical planting in China.Xu Chunlin Zhang Chengliang Li Lianhao Li Mingjin 2016International Journal of Agricultural and Biological Engineering2016,9,3:5
5A comparative study on different regeneration processes of Pt-Sn/γ-Al2O3 catalysts for propane dehydrogenation显示文摘Three different regeneration processes including hydrogen or nitrogen purging and coke-burning treatment were used to restore the Pt-Sn/γ-Al_2O_3 catalysts, through which propane dehydrogenation reaction was performed in a consecutive reaction-regeneration mode. It was found that the catalyst using hydrogen regeneration showed the best stability compared with those regenerated by nitrogen purging and coke-burning treatment, suggesting that hydrogen regeneration is an effective approach for maintaining the performance of Pt-Sn/γ-Al_2O_3 catalysts in propane dehydrogenation reaction. The effect of different regeneration atmospheres on the metal active center and the coke deposition was investigated by XRD,TEM, N_2-physisorption, TPO, TG and Raman technologies, and the results revealed that hydrogen or nitrogen regeneration resulted in little impact on the size and structure of metal active center, retaining the effective Pt Sn phase over the catalyst. Moreover, hydrogen regeneration not only removed the low dense components of the coke, but also altered the property of the residual coke through hydrogenation, leading to a higher mobility of coke, and thus a higher accessibility of the metal active centers. Whereas nitrogen regeneration only removed the low dense components of the coke. Although coke-burning regeneration caused a thorough coke removal, the catalyst subjected to repeated redox exhibited poor stability due to metal agglomeration, phase segregation and the resulting large Pt_3Sn particle and core-shell structure with a Sn-rich surface.Changyong Sun Junyin Luo Mingjin Cao Ping Zheng Guocheng Li Jiahao Bu Zhou Cao Shihong Chen Xiaowei Xie 2018Journal of Energy Chemistry2018,27,1:5
6A Modified Hadamard Based SLM without Side Information for PAPR Reduction in OFDM Systems显示文摘High peak-to-average power ratio(PAPR) is a concern in orthogonal frequency division multiplexing(OFDM) systems. Hadamard based selected mapping(HSLM) which uses Hadamard code as the phase sequence in selected mapping(SLM) is an attractive technique to reduce PAPR. But it requires sending side information(SI) to the receiver for each data block, and this results in a reduction in bandwidth efficiency. In this paper, we proposed a modified PAPR reduction method called semi-Hadamard based selected mapping(semi-HSLM) to decouple the phase information matrix into a phase rotation matrix for PAPR reduction and a SI matrix for side information hiding. We proposed a semi-hadamard matrix generation method to generate the phase rotation matrix, and designed a cyclic shift matrix as the SI matrix. Compared with the traditional HSLM, the semi-HSLM saves half of the phase storage and achieves good PAPR reduction performance.Ning Li Mingjin Li Zhongliang Deng 2019China Communications2019,16,12:3

15TRIM41 is required to innate antiviral response by polyubiquitinating BCL10 and recruiting NEMO显示文摘Sensing of pathogenic nucleic acids by pattern recognition receptors(PRR)not only initiates anti-microbe defense but causes inflammatory and autoimmune diseases.E3 ubiquitin ligase(s)critical in innate response need to be further identified.Here we report that the tripartite motif-containing E3 ubiquitin ligase TRIM41 is required to innate antiviral response through facilitating pathogenic nucleic acids-triggered signaling pathway.TRIM41 deficiency impairs the production of inflammatory cytokines and type I interferons in macrophages after transfection with nucleic acid-mimics and infection with both DNA and RNA viruses.In vivo,TRIM41 deficiency leads to impaired innate response against viruses.Mechanistically,TRIM41 directly interacts with BCL10(B cell lymphoma 10),a core component of CARD proteins-BCL10—MALT1(CBM)complex,and modifies the Lys63-linked polyubiquitylation of BCL10,which,in turn,hubs NEMO for activation of NF-kB and TANK-binding kinase 1(TBK1)—interferon regulatory factor 3(IRF3)pathways.Our study suggests that TRIM41 is the potential universal E3 ubiquitin ligase responsible for Lys63 linkage of BCL10 during innate antiviral response,adding new insight into the molecular mechanism for the control of innate antiviral response.Zhou Yu Xuelian Li Mingjin Yang Jiaying Huang Qian Fang Jianjun Jia Zheng Li Yan Gu Taoyong Chen Xuetao Cao 2021Signal Transduction and Targeted Therapy2021,6,3:1
