1Estimation of biomass in wheat using random forest regression algorithm and remote sensing data显示文摘Wheat biomass can be estimated using appropriate spectral vegetation indices.However,the accuracy of estimation should be further improved for on-farm crop management.Previous studies focused on developing vegetation indices,however limited research exists on modeling algorithms.The emerging Random Forest(RF) machine-learning algorithm is regarded as one of the most precise prediction methods for regression modeling.The objectives of this study were to(1) investigate the applicability of the RF regression algorithm for remotely estimating wheat biomass,(2) test the performance of the RF regression model,and(3) compare the performance of the RF algorithm with support vector regression(SVR) and artificial neural network(ANN) machine-learning algorithms for wheat biomass estimation.Single HJ-CCD images of wheat from test sites in Jiangsu province were obtained during the jointing,booting,and anthesis stages of growth.Fifteen vegetation indices were calculated based on these images.In-situ wheat above-ground dry biomass was measured during the HJ-CCD data acquisition.The results showed that the RF model produced more accurate estimates of wheat biomass than the SVR and ANN models at each stage,and its robustness is as good as SVR but better than ANN.The RF algorithm provides a useful exploratory and predictive tool for estimating wheat biomass on a large scale in Southern China.Li'ai Wang Xudong Zhou Xinkai Zhu Zhaodi Dong Wenshan Guo 2016The Crop Journal2016,4,3:30
2Simultaneous Optimization of Renewable Energy and Energy Storage Capacity with the Hierarchical Control显示文摘To fully consider the complementary role of different energy sources and reduce the curtailment of renewable energy(RE)in high RE penetration systems,a hierarchical optimization algorithm is proposed to simultaneously optimize the capacity of RE generation and energy storage systems(ESS).Time sequence simulation(TSS)technology is adopted to fully consider the regional RE resource characteristics and make the model more reliable.An optimization model for evaluating ESS capacity is established at a lower level.To overcome the high dimensional complexity of time sequence data,this paper re-formulates this sub-model as a consensus problem,which can be solved by a distributed approach to minimize the system’s total investment costs.At the upper level,the model for assessing the proportion of wind and solar capacity is developed by maximizing the RE generation.The golden section Fibonacci tree optimization(GSFTO)algorithm is utilized to improve the efficiency and solution accuracy.The results show that the algorithm and model are feasible and applicable for the identified purposes,which can provide a useful guidance for the development of power generation and the energy storage capacity in high RE penetration systems.Zhaodi Shi Weisheng Wang Yuehui Huang Pai Li Ling Dong 2022CSEE Journal of Power and Energy Systems2022,8,1:3
3Melatonin alleviates alcoholic liver disease via EGFR-BRG1-TERT axis regulation显示文摘Chronic alcohol consumption causes liver steatosis,cell death,and inflammation.Melatonin(MLT)is reported to alleviate alcoholic liver disease(ALD)-induced injury.However,its direct regulating targets in hepatocytes are not fully understood.In the current study,a cell-based screening model and a chronic ethanol-fed mice ALD model were used to test the protective mechanisms of MLT.MLT ameliorated ethanol-induced hepatocyte injury in both cell and animal models(optimal doses of 10μmol/L and 5 mg/kg,respectively),including lowered liver steatosis,cell death,and inflammation.RNA-seq analysis and loss-of-function studies in AML-12 cells revealed that telomerase reverse transcriptase(TERT)was a key downstream effector of MLT.Biophysical assay found that epidermal growth factor receptor(EGFR)on the hepatocyte surface was a direct binding and regulating target of MLT.Liver specific knock-down of Tert or Egfr in the ALD mice model impaired MLT-mediated liver protection,partly through the regulation of nuclear brahma-related gene-1(BRG1).Long-term administration(90 days)of MLT in healthy mice did not cause evident adverse effect.In conclusion,MLT is an efficacious and safe agent for ALD alleviation.Its direct regulating target in hepatocytes is EGFR and downstream BRG1-TERT axis.MLT might be used as a complimentary agent for alcoholics.Zhaodi Che Yali Song Chengfang Xu Wei Li Zhiyong Dong Cunchuan Wang Yixing Ren Kwok-Fai So George L.Tipoe Fei Wang Jia Xiao 2023Acta Pharmaceutica Sinica B2023,13,1:2
