| 1 | Closed-loop drip irrigation control using a hybrid wireless sensor and actuator network显示文摘In this research, a closed-loop drip irrigation control hybrid wireless sensor and actuator network (HWSAN) prototype were developed and deployed in a crop field for soil property precise measurement and precision irrigation in accordance with the measured soil property. The HWSAN was composed of a wireless sensor and actuator network (WSAN) used for in-field soil property monitoring and irrigation control and a laboratory supervising system. The WSAN included ten sensor nodes, five irrigation control nodes, a central node, a gateway and a cellular modem. The laboratory supervising system was formed by a web-server. The system could automatically sample soil properties including soil moisture, electrical conductivity, and nearsurface temperature at four different depths underground and transmit field data through cellular network to the web-server. Closed-loop control was achieved through the control nodes listening uploading packets from its paired sensor nodes to control drip irrigation. Results from the quality of service (QoS) evaluation included: the data packet transmission rate was 84.76%, data accuracy rate was greater than 97% and no in-field data transmission errors. | LI Zhen WANG Ning HONG TianSheng FRANZEN Aaron LI JiaNian | 2011 | Science China(Information Sciences)2011,54,3: | 7 |
| 2 | Microstructural evolution and tensile properties of low-carbon steel with martensitic microstructure during warm deforming and annealing显示文摘For preparing large-scale nano-grained and ultrafine-grained steel sheets by warm rolling and annealing,the effects of de- forming temperature on both the flow stress and the microstructure evolution of 09MnNiD steel with lath martensitic microstructure were studied by warm-compression test and transmission electron microscopy(TEM)observation.Thereafter,the steel with the lath martensitic structure was multi-pass warm-rolled and then annealed.TEM results indicate that nano-grained and ultrafine-grained steel sheets are formed by warm rolling at 400℃and annealing at 400-600℃.In comparison with the as-warm-rolled specimen,the tensile strength at room temperature changes a little when the rolled samples are annealed below 450℃,and the tensile strength is greatly lowered as the annealing temperature increases to above 550℃. | Yuwei Gao Tianfu Jing Guiying Qiao Jinku Yu Tiansheng Wang Qun Li Xinyu Song Shuqiang Wang Hong Gao | 2008 | Journal of University of Science and Technology Beijing2008,15,3: | 4 |

| 4 | Detection of citrus Huanglongbing based on image feature extraction and two-stage BPNN modeling显示文摘Citrus Huanglongbing(HLB),which is spread by the citrus psyllid,is the most destructive disease of citrus industry.While no effective cure for the disease has been reported,detection and removal of infected trees can prevent spreading.Symptoms indicative of HLB can be present in both HLB-positive trees and HLB-negative trees,making identification of infected trees difficult.A detection method for citrus HLB based on image feature extraction and two-stage back propagation neural network(BPNN)modeling was investigated in this research.The identification method for eight different classes including healthy,HLB and non-HLB symptoms was studied.Thirty-four statistical features including color and texture were extracted for each leaf sample,following the two-stage BPNN to model and identify HLB-positive leaves from HLB-negative leaves.The discrimination accuracy can reach approximately 92%which shows that this method based on visual image processing can perform well in detecting citrus HLB. | Deng Xiaoling Yubin Lan Xing Xiaqiong Mei Huilan Liu Jiakai Hong Tiansheng | 2016 | International Journal of Agricultural and Biological Engineering2016,9,6: | 2 |

| 7 | Room temperature H_2S micro-sensors with anti-humidity properties fabricated from NiO-In_2O_3 composite nanofibers显示文摘NiO-In2O3 composite nanofibers are synthesized via electrospinning and calcining techniques.Micro-sensors are fabricated by sputtering Pt electrodes on Si chips to form sensor substrates,and then spinning the NiO-In2O3 composite nanofibers onto the sensor substrate surface.The as-fabricated micro-sensors exhibit excellent H2S sensing properties at room temperature.The sensitivity of the micro-sensors is up to 6 when the sensors are exposed to 3μL/LH2S,and the corresponding response and recovery times are 14 and 22 s,respectively.The micro-sensors also exhibit high selectivity and good stability.Especially,the micro-sensors can operate at various humidity conditions.The sensitivity of the micro-sensors is 3.8 to 3μL/LH2S at 75% relative humidity.These characteristics make the micro-sensors good candidates for practical H2S sensors with high performance. | YUE XueJun HONG TianSheng YANG Zhou HUANG ShuangPing | 2013 | Science China(Technological Sciences)2013,56,3: | 1 |
| 8 | Promotion of liquid-to-solid phase transition of cGAS by Baicalein suppresses lung tumorigenesis显示文摘Dear Editor,Kras and p53 mutation are among the most common gene mutations in lung cancer,which has both the highest incidence and mortality rate among cancers.1 Kras/p53 mutation also causes mitochondrial dysfunction,which has been implicated to promote the inflammation-to-cancer transition.2 We established a lung adenocarcinoma model by using conditional alleles of KrasLSLG12D/p53flox/flox in mice3 to evaluate the effect of Baicalein(5,6,7-trihydroxyflavone),a principal component of Scutellaria baicalensis in traditional Chinese medicine,4 on the initiation and progression of lung cancer.Cre-mediated expression of KrasG12D and deletion of p53 caused obvious tumor lesions in the lung,which were strongly inhibited by the administration of Baicalein(Fig.1a,b and Supplementary Fig.1a,b),indicating that Baicalein is highly potent in inhibiting the progression of primary lung cancer. | Tiansheng Zheng Haipeng Liu Yifan Hong Yajuan Cao Qing Xia Chengge Qin Ming Li Russel J.Reiter Yidong Bai Lihong Fan | 2023 | Signal Transduction and Targeted Therapy2023,8,4: | 0 |
