| 1 | Limit analysis on seismic stability of anisotropic and nonhomogeneous slopes with anti-slide piles显示文摘This study employs the limit analysis method to evaluate the seismic stability of anisotropic and nonhomogeneous slopes stabilized with anti-slide piles. The pseudo-static approach is used to simplify the earthquake load. The yield seismic acceleration factor is obtained from the optimization procedure and the results are verified with the published data. Then, the seismically-unstable slope is reinforced with anti-slide piles, and the seismic stability of the reinforced slope is explored. The results show that the anisotropy and nonhomogeneity of soils have significant effects on the stabilizing force required from the anti-slide piles and the optimal location of the pile is near the toe of the slope. | GONG WeiBing LI JingPei LI Lin | 2018 | Science China(Technological Sciences)2018,61,1: | 7 |
| 2 | Printed stretchable circuit on soft elastic substrate for wearable application显示文摘In this paper, a flexible and stretchable circuit has been fabricated by the printing method based on Ag NWs/PDMS composite. The randomly oriented Ag NWs were buried in PDMS to form a conductive and stretchable electrode. Stable conductivity was achieved with a large range of tensile strain(0-50%) after the initial stretching/releasing cycle. The stable electrical response is due to the buckling of the Ag NWs/PDMS composite layer. Furthermore, printed stretchable circuits integrated with commercial ICs have been demonstrated for wearable applications. | Wei Yuan Xinzhou Wu Weibing Gu Jian Lin Zheng Cui | 2018 | Journal of Semiconductors2018,39,1: | 4 |
| 3 | Porosity Prediction from Well Logs Using Back Propagation Neural Network Optimized by Genetic Algorithm in One Heterogeneous Oil Reservoirs of Ordos Basin, China显示文摘A reliable and effective model for reservoir physical property prediction is a key to reservoir characterization and management.At present,using well logging data to estimate reservoir physical parameters is an important means for reservoir evaluation.Based on the characteristics of large quantity and complexity of estimating process,we have attempted to design a nonlinear back propagation neural network model optimized by genetic algorithm(BPNNGA)for reservoir porosity prediction.This model is with the advantages of self-learning and self-adaption of back propagation neural network(BPNN),structural parameters optimizing and global searching optimal solution of genetic algorithm(GA).The model is applied to the Chang 8 oil group tight sandstone of Yanchang Formation in southwestern Ordos Basin.According to the correlations between well logging data and measured core porosity data,5 well logging curves(gamma ray,deep induction,density,acoustic,and compensated neutron)are selected as the input neurons while the measured core porosity is selected as the output neurons.The number of hidden layer neurons is defined as 20 by the method of multiple calibrating optimizations.Modeling results demonstrate that the average relative error of the model output is 10.77%,indicating the excellent predicting effect of the model.The predicting results of the model are compared with the predicting results of conventional multivariate stepwise regression algorithm,and BPNN model.The average relative errors of the above models are 12.83%,12.9%,and 13.47%,respectively.Results show that the predicting results of the BPNNGA model are more accurate than that of the other two,and BPNNGA is a more applicable method to estimate the reservoir porosity parameters in the study area. | Lin Chen Weibing Lin Ping Chen Shu Jiang Lu Liu Haiyan Hu | 2021 | Journal of Earth Science2021,32,4: | 3 |
| 4 | Preparation and MRI performances of core-shell structural PEG salicylic acid-gadolinium composite nanoparticles显示文摘Gadolinium(Ⅲ)-based T_(1) contrast agents have been widely used in clinical MRI.In this study,salicylic acid-gadolinium chelate was prepared via directly coordination reaction of gadolinium ion and salicylic acid.Then,three polyethylene glycols with different molecular weight were modified on the surface of salicylic acid-gadolinium by simple chemical coupling to construct three core-shell structural Gd based composites.The scanning electron microscopy(SEM)and transmission electron microscopy(TEM)characterization results show that the composite is a spherical particle with a diameter of about 100-200 nm.The longitudinal relaxation rate r_(1) of the Gal-PEG-2000 is 11.097(mmol/L)^(-1)/s,and the ratio of r_(2)/r_(1) is as low as 2.53.The composite shows good liver and intestines MRI performances after being used in in vivo imaging,showing a good prospect of biological application. | Jia Zhang Zhiyan Lin Minzhi Zhao Weibing Xu Fang Nian | 2022 | Journal of Rare Earths2022,40,7: | 1 |
| 5 | Expert Consensus on Nutritional Support for Children with Congenital Heart Disease(2023 Edition)显示文摘The second edition of the expert consensus on pediatric nutrition was formed based on a global update of pedia-tric nutrition guidelines or consensus worldwide,the management of congenital heart disease,and the results of multi-center clinical nutrition research for congenital heart disease following thefirst Chinese consensus edition of 2016.The consensus was also shaped by the results of three discussion sessions and two questionnaires con-ducted by the 13-member collaboration group.This process was informed by both clinical guidelines and expert consensus.The quality of literature,both in English and Chinese,and the level of recommendations were evaluated using the Grading of Recommendations Assessment,Development,and Evaluations(GRADE)system. | Xuming Mo Wei Cai Jirong Qi Zhuoming Xu Ying Wang Weihui Yan Shoujun Li Nianguo Dong Xinxin Chen Jinfen Liu Qiang Shu Jimei Chen Haibo Zhang Hao Zhang Quansheng Xing Qi An Xiaofeng Li Xu Wang Yan He Junwu Su Taibing Fan Teng Ming Weibing Tang Li Hong Jinghao Zheng Ming Ye Guocheng Sun Yiqun Ding Liang Tao Yifeng Yang Zhongshi Wu Hua Cao Qiang Wang Keming Yang Libing Zhang Ping Wen Yanqin Cui Bo Zhai Yong Zou Qingya Tang Rui Chen Chun Wu Zhiyu Feng Caixia Liu Yaping Mi Rufang Zhang Ke Lin Xin Li Mingan Pi Xiangming Fan Shanshan Shi Peng Huang Zhengxia Pan Jiafeng Qi Renwei Chen Shuguang Tao Yaqin Shu Huifeng Zhang Lan Jiang Min Da Nishant Patel Liang Hu Cardiac Surgery Group of Pediatric Surgery Society of Chinese Medical Association and Parenteral Enteral Nutrition Society of Chinese Medical Association | 2023 | Congenital Heart Disease2023,18,6: | 0 |
