1Monetary Policy and Corporate Investment:Evidence from Chinese Micro Data显示文摘This paper investigates how a firm’s characteristics restrict the influence of monetary policy changes on its investment behavior.Focusing on China ’s listed companies for a sample period from the first quarter of 2002 to the first quarter of 2011,we find that quantityoriented and price-based monetary policies have heterogeneous impacts on corporate investment behavior,but the influence of monetary policies is constrained by the liquidity, inventory,size and asset-liability ratio of a firm.Firms with higher liquidity,lower inventory level and lower asset-liability ratios are less sensitive to the impact from two kinds of monetary policies.The larger the size of the firm,the less it is subject to influence from quantity-oriented monetary policy;it responds more to price-based monetary policy.The policy implication is that the monetary authorities should pay attention to the importance of policy-making based on the monetary demand of microeconomic entities.Ying Sophie Huang Frank M.Song Yizhong Wang 2012China & World Economy2012,20,5:12
2Integrated transcriptomic and metabolomic analyses of a wax deficient citrus mutant exhibiting jasmonic acid-mediated defense against fungal pathogens显示文摘Naturally,resistant crop germplasms are important resources for managing the issues of agricultural product safety and environment deterioration.We found a spontaneous mutant of‘Newhall’navel orange(Citrus sinensis Osbeck)(MT)with broad-spectrum protections against fungal pathogens in the orchard,postharvest-storage,and artificial inoculation conditions.To understand the defense mechanism of MT fruit,we constructed a genome-scale metabolic network that integrated metabolome and transcriptome datasets.The coordinated transcriptomic and metabolic data were enriched in two sub-networks,showing the decrease in very long chain fatty acid(by 41.53%)and cuticular wax synthesis(by 81.34%),and increase in the synthesis of jasmonic acid(JA)(by 95.23%)and JA-induced metabolites such as 5-dimethylnobietin(by 28.37%)in MT.Furthermore,cytological and biochemical analyses confirmed that the response to fungal infection in MT was independent of wax deficiency and was correlated with the levels of jasmonates,and the expression of plant defensin gene PDF1.2.Results of exogenous application of MeJA and JA inhibitors such as propyl gallate proved that JA-mediated defense contributes to the strong tolerance against pathogens in MT.Our results indicated that jasmonate biosynthesis and signaling are stimulated by the fatty acid redirection of MT,and participate in the tolerance of pathogenic fungi.Yizhong He Jingwen Han Runsheng Liu Yuduan Ding Jinqiu Wang Li Sun Xiaoming Yang Yunliu Zeng Weiwei Wen Juan Xu Hongming Zhang Xiang Yan Zhaoxing Chen Zuliang Gu Hong Chen Huanqing Tang Xiuxin Deng Yunjiang Cheng 2018Horticulture Research2018,5,1:8
3Interest Rate Pass-through in a Dual-track System:Evidence from China显示文摘Using the Phillips-Loretan approach,this paper verifies the degree and speed of passthrough and rigidity of different interest rates in China,as well as the response of private loan interest rates to other interest rates during 2002-2012.The results indicate that the long-term pass-through from the interbank offered rates and deposit and loan interest rates to the treasury bond rate is incomplete,but that the long-term pass-through to private loan interest rates is overshooting.The long-term pass-through from the deposit and loan interest rates to the overnight interbank offered rate is incomplete,while that to the interbank offered rates of other maturities is complete.The short-term passthrough and adjustment speed of interest rates exhibit asymmetry.Therefore,before considering a full liberalization of interest rates,it is important to further enhance the competition of the financial system and the function of different interest rate systems,such as the interbank market and bond market.Xuejun Jin Frank M.Song Yizhong Wang Yi Zhong 2014China & World Economy2014,22,4:7
4Antiferromagnetic element Mn modified PtCo truncated octahedral nanoparticles with enhanced activity and durability for direct methanol fuel cells显示文摘Pt-based magnetic nano catalysts are one of the most suitable cand idates for electrocatalytic materials due to their high electrochemistry activity and retrievability.Unfortunately,the inferior durability prevents them from being scaled-up,limiting their commercial applications.Herein,an antiferromagnetic element Mn was introduced into PtCo nanostructured alloy to synthesize uniform Mn-PtCo truncated octahedral nanoparticles(TONPs)by one-pot method.Our results show that Mn can tune the blocking temperature of Mn-PtCo TONPs due to its an tiferromag netism.At low temperatures,Mn-PtCo TONPs are ferromag netic,and the coercivity in creases gradually with in creasi ng Mn contents.At room temperature,the Mn-PtCo TONPs display superparamag netic behavior,which is greatly helpful for in dustrial recycling.Mn doping can not only modify the electronic structure of PtCo TONPs but also enhanee electrocatalytic performance for methanol oxidation reaction.The maximum specific activity of Mn-PtCo-3 reaches 8.1 A`m^-2,3.6 times of commercial Pt/C(2.2 A·m^-2)and 1.4 times of PtCo TONPs(5.6 A`m^-2),respectively.The mass activity decreases by only 30%after 2,000 cycles,while it is 45%and 99%(nearly inactive)for PtCo TONPs and commercial Pt/C catalysts,respectively.Qiqi Zhang Jialong Liu Tianyu Xia Jie Qi Haochang Lyu Baoyuan Luo Rongming Wang Yizhong Guo Lihua Wang and Shouguo Wang 2019Nano Research2019,12,10:5
5Feed intake prediction model for group fish using the MEA-BP neural network in intensive aquaculture显示文摘In aquaculture,the accurate prediction of feed intake for group fish is considered to be crucial to any feeding system.Previous studies mainly used mathematical statistics to establish the mapping relationship between feed intake and influencing factors.The result was easily influenced by subjective experience.To solve the above issues,this paper proposed a feed intake prediction model for group fish using the back-propagation neural network(BPNN)and mind evolutionary algorithm(MEA).Firstly,four factors,including water temperature,dissolved oxygen,the average fish weight and the number of fish were selected as the input of the BPNN model.Secondly,the initial weight and threshold of the BPNN were optimized by the MEA to improve the matching precision.Finally,the prediction model was achieved after training.Experimental results showed that the correlation coefficient between the predicted and measured values reached 0.96.And the root mean squared error,mean square error,mean absolute error,mean absolute percent error of the model was 6.89,47.53,6.17 and 0.04,respectively.In addition,the proposed method also had the better nonlinear fitting ability than BPNN and GA-BP.By using an intelligent optimization algorithm,the mapping relationship between fish intake and environmental factors was automatically established,thus avoiding the subjectivity of traditional methods.Therefore,it can lay a theoretical foundation for the development of intelligent feeding equipment and meet the needs of the smart fishery.Lan Chen Xinting Yang Chuanheng Sun Yizhong Wang Daming Xu Chao Zhou 2020Information Processing in Agriculture2020,7,2:5
6Robust adaptive control for interval time-delay systems显示文摘This paper focuses on the robust adaptive control problems for a class of interval time-delay systems and a class of large-scale interconnected systems. The nonlinear uncertainties of the systems under study are bounded by high- order polynomial functions with unknown gains. Firstly, the adaptive feedback controller which can guarantee the stability of the closed-loop system in the sense of uniform ultimate boundedness is proposed. Then the proposed adaptive idea is extended to robust stabilizing designing method for a class of large-scale interconnected systems. Here, another problem we address is to design a decentralized feedback adaptive controller such that the closed-loop system is stable in the sense of uniform ultimate boundedness for all admissible uncertainties and time-delay. Finally, an illustrative example is given to show the validity of the proposed approach.Yizhong WANG Huaguang ZHANG Jun YANG 2006控制理论与应用(英文版)2006,4,4:4
7In situ atomic-scale observation of dislocation behaviors in twin-structured Pt nanocrystals显示文摘The deformation mechanisms of twin-structured metallic materials have attracted great interest.Though previous theoretical predictions have suggested that the repulsive force of the twin boundary(TB)can significantly affect the deformation of twinstructured metals,it remains unclear whether this prediction applies to experimental conditions.In this paper,the atomic-scaled deformation process of twin-structured Pt nanocrystals was in situ observed using our home-made device in a high-resolution transmission electron microscope.We have shown that the plastic deformation of the twin-structured Pt nanocrystals was governed by full dislocation generation as well as Lomer dislocation(LD)lock formation and destruction.After LD locks were destructed,these full dislocations tended to move towards the surface of the nanocrystals.The findings revealed that due to the ultra-high repulsive force of TB on dislocation,there was no dislocation-TB reaction during the deformation.These findings can enrich our understanding of the dislocation behaviors of twin-structured nanocrystals.GUO YiZhong SUN Tao FU LiBo HAO LongHu HUANG Ming WEI RuJian LUO JunFeng HE Xin WANG XingQuan XIONG XiaoDong WANG LiHua HAN XiaoDong 2021Science China(Technological Sciences)2021,64,3:2
8Food Safety Risks and Contributing Factors of Cronobacter spp.显示文摘Cronobacter species are a group of Gram-negative opportunistic pathogens,which cause meningitis,sep-ticemia,and necrotizing enterocolitis in neonates and infants,with neurological sequelae in severe cases.Interest in Cronobacter has increased significantly in recent years due to its high virulence in children.In this review,we summarize the current understanding of the prevalence of Cronobacter species in several important food types.We discuss the response mechanisms enabling persistence in adverse growth con-ditions,as well as its pathogenicity.We emphasize the food safety concerns caused by Cronobacter and subsequent control methods and clinical treatments.Na Ling Xiuting Jiang Stephen Forsythe Danfeng Zhang Yizhong Shen Yu Ding Juan Wang Jumei Zhang Qingping Wu Yingwang Ye 2022Engineering2022,8,5:2
