| 1 | Ergodic degrees for continuous-time Markov chains显示文摘This paper studies the existence of the higher orders deviation matrices for continuous time Markov chains by the moments for the hitting times. An estimate of the polynomial convergence rates for the transition matrix to the stationary measure is obtained. Finally, the explicit formulas for birth-death processes are presented. | MAO Yonghua | 2004 | Science China Mathematics2004，47，2： | 18 |
| 2 | Reappearance of Risk of Schistosomiasis Transmission and the Response After 27 Years of Interrupted Transmission—Guangdong Province,China,2019显示文摘Summary What is already known about this topic?No live specimens of the snail Oncomelania hupensis(O.hupensis)and indigenous infected cases of schistosomiasis japonicum have been found in Guangdong Province since 1993,but live O.hupensis was found again in 2019.This study conducted O.hupensis identification and elimination.What is added by this report?In 2019,live O.hupensis specimens were detected by routine surveillance in areas in Qujiang of Shaoguan City and Yingde of Qingyuan City,and an emergency response was launched immediately. | Shaoyu Huang Qiang Mao Qili Zhong Xiuhong Fan Weiquan Li Yonghua Rao Fuquan Pei Shizhu Li Zhuohui Deng | 2021 | China CDC weekly2021，3，51： | 4 |
| 3 | Assessment of estrogen disrupting potency in animal foodstuffs of China by combined biological and chemical analyses显示文摘Food has been documented as one of major routes for human exposure to environmental estrogens(EEs), but information on the occurrence of EEs in animal foodstuffs is still scarce.This study analyzed estrogenic activity in 16 types of animal foodstuffs(n = 142) collected from four cities(Wuhan, Guangzhou, Wenzhou and Yantai) of China by combined yeast estrogen screen(YES) bioassay and chemical analysis. By bioassay, all samples' extracts were found to induce estrogenic activities and the bioassay-derived 17β-estradiol equivalent(EEQbio) ranged from 8.29 to 118.32 ng/g. In addition, the samples were analyzed by liquid chromatography coupled to tandem mass spectrometry for further chemical analysis. 17β-Estradiol was found in all samples in this survey at levels of 0.44 to 15.04 ng/g.All samples had 33.1% detection rate of 17α-ethinylestradiol(EE2), and the maximum concentration was 2.80 ng/g. Bisphenol A and 4-nonylphenols were detected in 83.8% and83.1% of samples, with concentrations up to 12.56 ng/g and 35.76 ng/g, respectively.However, the concentrations of estrone, diethylstilbestrol and 4-t-octylphenol were found to be below the limit of detection. A comparison of EEQbiomeasured from the YES assay and EEQchemcalculated from chemical analysis showed good correlation(R2= 0.84). Based on the results, the YES assay can be used as a rapid pre-screening method for monitoring the levels of estrogenic activity in large numbers of animal foodstuffs, and chemical analysis used in combination can be used for the identification of specific EEs. | Jun Wang Wei Xia Yonghua Xiao Chenjiang Ying Jia Long Hui Zhang Xi Chen Congda Mao Xiumin Li Lin Wang Shunqing Xu | 2014 | Journal of Environmental Sciences2014，26，10： | 4 |

| 15 | Leaky Gut Plays a Critical Role in the Pathophysiology of Autism in Mice by Activating the Lipopolysaccharide‑Mediated Toll‑Like Receptor 4-Myeloid Differentiation Factor 88-Nuclear Factor Kappa B Signaling Pathway显示文摘Increased intestinal barrier permeability,leaky gut,has been reported in patients with autism.However,its contribution to the development of autism has not been determined.We selected dextran sulfate sodium(DSS)to disrupt and metformin to repair the intestinal barrier in BTBR T+tf/J autistic mice to test this hypothesis.DSS treatment resulted in a decreased affinity for social proximity;however,autistic behaviors in mice were improved after the administration of metformin.We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors.The concentration of lipopolysaccharides in blood decreased after the administration of metformin.The expression levels of the key molecules in the toll-like receptor 4(TLR4)–myeloid differentiation factor 88(MyD88)–nuclear factor kappa B(NF-κB)pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed.Thus,“leaky gut”could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4–MyD88–NF-κB pathway. | Fang Li Haoran Ke Siqi Wang Wei Mao Cexiong Fu Xi Chen Qingqing Fu Xiaori Qin Yonghua Huang Bidan Li Shibing Li Jingying Xing Minhui Wang Wenlin Deng | 2023 | Neuroscience Bulletin2023，39，6： | 0 |
| 16 | The proposed role of MSL-lncRNAs in causing sex lability of female poplars显示文摘Labile sex expression is frequently observed in dioecious plants,but the underlying genetic mechanism remains largely unknown.Sex plasticity is also observed in many Populus species.Here we carried out a systematic study on a maleness-promoting gene,MSL,detected in the Populus deltoides genome.Our results showed that both strands of MSL contained multiple cis-activating elements,which generated long non-coding RNAs(lncRNAs)promoting maleness.Although female P.deltoides did not have the male-specific MSL gene,a large number of partial sequences with high sequence similarity to this gene were detected in the female poplar genome.Based on sequence alignment,the MSL sequence could be divided into three partial sequences,and heterologous expression of these partial sequences in Arabidopsis confirmed that they could promote maleness.Since activation of the MSL sequences can only result in female sex lability,we propose that MSL-lncRNAs might play a role in causing sex lability of female poplars. | Jinyan Mao Suyun Wei Yingnan Chen Yonghua Yang Tongming Yin | 2023 | Horticulture Research2023，10，5： | 0 |

| 18 | Image Segmentation via Fischer-Burmeister Total Variation and Thresholding显示文摘Image segmentation is a significant problem in image processing.In this paper,we propose a new two-stage scheme for segmentation based on the Fischer-Burmeister total variation(FBTV).The first stage of our method is to calculate a smooth solution from the FBTV Mumford-Shah model.Furthermore,we design a new difference of convex algorithm(DCA)with the semi-proximal alternating direction method of multipliers(sPADMM)iteration.In the second stage,we make use of the smooth solution and the K-means method to obtain the segmentation result.To simulate images more accurately,a useful operator is introduced,which enables the proposed model to segment not only the noisy or blurry images but the images with missing pixels well.Experiments demonstrate the proposed method produces more preferable results comparing with some state-of-the-art methods,especially on the images with missing pixels. | TingtingWu Yichen Zhao Zhihui Mao Li Shi Zhi Li Yonghua Zeng | 2022 | Advances in Applied Mathematics and Mechanics2022，14，4： | 0 |
