| 1 | Linearity analysis of closed-loop capacitive accelerometer due to distance mismatch between plates and the influence of compensation capacitor array显示文摘This paper presents mathematical formulae showing that the distance mismatch for an uncentered proof mass in an accelerator sensor does not influence the linearity of the closed-loop accelerometer as a whole.This asymmetry in sensors only introduces an output voltage offset in the readout integrated circuit.Numerical simulation using Matlab/Simulink confirms the mathematical conclusion.The linear response after compensation with a conventional capacitor array is also simulated and analyzed.Results show that there is a loss in linearity.Similar results hold not only for the continuous-time architecture,but also for a time-divided architecture.A readout integrated circuit with a time-divided architecture is designed and fabricated using a 0.35μm HV CMOS process.An accelerometer composed of a microelectromechanical system sensor with severe built-in distance mismatch and the designed readout integrated circuit is tested.Test results show that the nonlinearity of such accelerometer is within 0.3%. | HUANG JingQing ZHAO Meng ZHANG TingTing CHEN ZhongJian HONG LiChen WU Feng ZHANG YaCong LU WenGao GAO ChengChen HAO YiLong | 2014 | Science China(Information Sciences)2014，57，6： | 2 |

| 4 | Effects of Paclobutrazol on Physiological Parameters of Dahlia under Heat Stress显示文摘[Objectives] This study was conducted to investigate the effect of paclobutrazol( PBZ) on heat tolerance of dahlia. [Methods]A dahlia variety Danbanhuang was selected as the experimental material in this study. After 100,200,300 or 400 mg/L paclobutrazol was sprayed evenly to the leaves of dahlia seedlings,they were cultured in an incubator at high temperature( 35 ℃/30 ℃,day/night) for two days,and then transferred to an incubator at normal temperature( 25 ℃/20 ℃,day/night). The physiological and biochemical parameters of the dahlia seedlings were measured before exposure to high temperature( D0),after exposure to high temperature for two days( D2) and exposure to normal temperature for one day( R1). [Results]Compared to the negative control,foliar application of paclobutrazol decreased the content of MDA,increased the contents of chlorophyll,proline,soluble protein,and the activity of SOD,POD and CAT in dahlia plants under heat stress. The contents of MDA,soluble protein and proline in PBZ treated dahlia plants increased when they were subject to high temperature stress( 35 ℃/30 ℃,day/night),and then decreased when the temperature returned to normal( 25 ℃/20 ℃,day/night),and CAT activity decreased at high temperature,and then increased at normal temperature,while the activity of SOD and POD kept rising during the entire experimental period. [Conclusions]Foliar application of paclobutrazol can alleviate the adverse effect caused by high temperature to dahlia plants,and the experimental data provide a theoretical basis for the application of paclobutrazol in dahlia cultivation in South China. | Chuanle ZHAO Hua GUAN Xianfeng YUAN Xiuxiu LI Le GAO Chengchen SHEN Jianzhong TAN | 2018 | Agricultural Biotechnology2018，7，5： | 1 |
| 5 | 1-DE/MS Analysis of the Proteins Related to Spathe Color Variation in Anthurium andraeanum 'Madural'显示文摘In order to understand the mechanism of spathe color variation in Anthurium andraeanum at the protein level, the leaves, inflorescences and spathes of the wild type and two mutants of A. andraeanum 'Madural' were used as research objects in which the differential expression of proteins related to flower color mutants was analyzed by one-dimensional electrophoresis and mass spectrometry(1-DE/MS). The 1-DE patterns showed that the protein components expressed highly in spathes were mainly concentrated in the molecular weight range of 20-42 kD, and differential bands were detected between the wild type and the mutant, while no significant differences were detected in the leaf and inflorescence proteins. According to the results of mass spectrometry analysis of the differential bands, 21 known functional proteins involved in life processes such as glucose metabolism, resistance, cytoskeleton, gene regulation and signal transduction were identified. It showed that in addition to the influences from anthocyanidins, the spathe color variation of A. andraeanum 'Madural' is also regulated by a variety of metabolic pathway-related proteins. | Le GAO Lan LUO Chengchen SHEN Yichun HU Xia XIAO Jianzhong TAN | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
| 6 | An interactive web-based solar energy prediction system using machine learning techniques显示文摘Solar energy being one of the most inexpensive renewable energy sources,has shown to be a viable alternative to traditional fossil-fuel and wood-based electricity generation.For the purpose of creating a more trustworthy and successful energy planning strategy,accurate projections of sun irradiation,solar energy generation,and revenues are crucial.Hence,in this work we have proposed webbased optimal prediction system that estimates solar radiation based on location and meteorological data using Machine Learning techniques.Furthermore,an interactive dashboard solar digital map has been developed that enables real-time investigation of solar energy consumption,production,solar radiation,and investment potential for a specific county in California.The model’s performance has been measured using Root Mean Square Error(RMSE),Mean Square Error(MSE),Mean Average Error(MAE),and Mean Absolute Percentage Error(MAPE)scores.Experimental results demonstrate that stacking model outperformed all the models with the lowest RMSE,MSE,and MAE. | Priyanka Chawla Jerry Zeyu Gao Teng Gao Chengchen Luo Huimin Li Yiqin We | 2023 | Journal of Management Analytics2023，10，2： | 0 |
