| 1 | Health evaluation method for degrading systems subject to dependent competing risks显示文摘This paper proposes a health evaluation method for degrading systems subject to competing risks of dependent soft and hard failures. To characterize the time-varying degradation rate, the degradation process is determined by a non-stationary Gamma process and the soft failure is encountered when it exceeds a predefined critical level. For the hard failure, a Cox's proportional hazard model is applied to describe the hazard rate of the time to system failure. The dependent relationship is modeled by incorporating the degradation process as a time-varying covariate into the Cox's proportional hazard model. To facilitate the health characteristics evaluation, a discretization technique is applied both to the degradation process and the monitoring time.All health characteristics can be obtained in the explicit form using the transition probability matrix, which is computationally attractive for practical applications. Finally, a numerical analysis is carried out to show the effectiveness and the performance of the proposed health evaluation method. | ZHAO Shuai MAKIS Viliam CHEN Shaowei LI Yong | 2018 | Journal of Systems Engineering and Electronics2018，29，2： | 3 |

| 8 | Nanowrinkled Carbon Aerogels Embedded with FeN_(x) Sites as Effective Oxygen Electrodes for Rechargeable Zinc-Air Battery显示文摘Rational design of single-metal atom sites in carbon substrates by a flexible strategy is highly desired for the preparation of high-performance catalysts for metal-air batteries.In this study,biomass hydrogel reactors are utilized as structural templates to prepare carbon aerogels embedded with single iron atoms by controlled pyrolysis.The tortuous and interlaced hydrogel chains lead to the formation of abundant nanowrinkles in the porous carbon aerogels,and single iron atoms are dispersed and stabilized within the defective carbon skeletons.X-ray absorption spectroscopy measurements indicate that the iron centers are mostly involved in the coordination structure of FeN_(4),with a minor fraction(ca.1/5)in the form of FeN_(3)C.First-principles calculations show that the FeN_(x) sites in the Stone-Wales configurations induced by the nanowrinkles of the hierarchically porous carbon aerogels show a much lower free energy than the normal counterparts.The resulting iron and nitrogen-codoped carbon aerogels exhibit excellent and reversible oxygen electrocatalytic activity,and can be used as bifunctional cathode catalysts in rechargeable Zn-air batteries,with a performance even better than that based on commercial Pt/C and RuO_(2) catalysts.Results from this study highlight the significance of structural distortions of the metal sites in carbon matrices in the design and engineering of highly active single-atom catalysts. | Ting He Bingzhang Lu Yang Chen Yong Wang Yaqiang Zhang John L.Davenport Alan P.Chen Chih-Wen Pao Min Liu Zhifang Sun Alexander Stram Alexander Mordaunt Jairo Velasco Jr Yuan Ping Yi Zhang Shaowei Chen | 2019 | Research2019，，1： | 1 |
| 9 | The NAC transcription factor CINAC68 positively regulates sugar content and seed development in watermelon by repressing CIINV and CIGH3.6显示文摘NAC(NAM,ATAF1/2,and CUC2)transcription factors play important roles in fruit ripening and quality.The watermelon genome encodes 80 NAC genes,and 21 of these NAC genes are highly expressed in both the flesh and vascular tissues.Among these genes,CINAC68 expression was signi fi cantly higher in flesh than in rind.However,the intrinsic regulatory mechanism of CINAC68 in fruit ripening and quality is still unknown.In this study,we found that ClNAC68 is a transcriptional repressor and that the repression domain is located in the C-terminus.Knockout of CINAC68 by the CRISPR-Cas9 system decreased the soluble solid content and sucrose accumulation in mutant flesh.Development was delayed,germination was inhibited,and the IAA content was signi ficantly decreased in mutant seeds.Transcriptome analysis showed that the invertase gene CUNV was the only gene involved in sucrose metabolism that was upregulated in mutant flesh,and expression of the indole-3-acetic acid-amido synthetase gene CIGH3.6 in the IAA signaling pathway was also induced in mutant seeds.EMSA and dual-luciferase assays showed that CINAC68 directly bound to the promoters of CUNV and CIGH3.6 to repress their expression.These results indicated that CINAC68 positively regulated sugar and IAA accumulation by repressing CUNV and CIGH3.6.Our findings provide new insights into the regulatory mechanisms by which NAC transcription factors affect fruit quality and seed development. | Jinfang Wang Yanping Wang Jie Zhang Yi Ren Maoying Li Shaowei Tian Yongtao Yu Yi Zuo Guoyi Gong Haiying Zhang Shaogui Guo Yong Xu | 2021 | Horticulture Research2021，8，1： | 0 |
