1Development and performance evaluation of an innovative low-cost seismic isolator显示文摘This paper proposes an innovative low-cost isolator with lightweight and cost-effective features for use in low-rise residential buildings.The low-cost laminated isolator is formed by plastic shims with unsaturated polyester fiber reinforcement between rubber layers.Performance tests are systematically carried out to characterize the isolator in terms of mechanic behavior(e.g.,compression,shear,and their relationship),dynamic properties(e.g.,damping),and ultimate states.A design guideline and associated criteria of the low-cost isolator are also provided and discussed in this study.To investigate more detailed behavior,a finite element model of the isolator is developed in ABAQUS and calibrated by the experimental data.The research presented in this paper makes significant contributions to the evaluation of the peak stress and strain demands on isolator’s components and provides technical support for the design and manufacturing of this new type of isolator.TAN Ping XU Kai WANG Bin CHANG ChiaMing LIU Han ZHOU FuLin 2014Science China(Technological Sciences)2014,57,10:5

4Szabo技术在口部病变经皮冠状动脉介入治疗中应用的安全性和可行性(英文)显示文摘背景和目的:冠状动脉口部病变的经皮冠状动脉介入(PCI)治疗手术操作难度大,易有并发症,既要支架准确植入口部病变,又要边支不受压。本研究探讨解决这一难题的Szabo技术的成功率、安全性和可行性。方法:Szabo技术是利用边支导丝(抛锚导丝)穿过支架最靠近边支的支架网眼,防止支架前进时停止在口部病变外,保证主支导丝穿过支架腔。作者回顾性分析利用Szabo技术治疗39例病人冠状动脉口部病变的结果。手术操作成功定义:支架没有脱落,边支导丝没有退出。造影成功定义:支架准确植入到口部,而边支没有受压。血管内超声定义成功:支架准确植入到口部,近段没有突出,支架完全覆盖病变。39例病人中,男性28例,女性11例,年龄43~79,平均(65±12)岁。6F和7F指引导管分别用于35例(89.7%)和4(10.3%)例病人。经桡动脉途径31(79.5%)例和经股动脉途径8(20.5%)例。病变相关血管:前降支(LAD)26(66.7%)例,右冠(RCA)5(12.8%)例,旋支及钝缘支(LCX-OM)3(7.7%)例,后降支(PDA)5(12.8%)例。支架植入后30(76.9%)例病变相关血管和9(23.1%)例边支血管经过了血管内超声(IVUS)检查。结果:手术操作成功:36例(92.3%),这36例造影均成功(100%)。IVUS检测:支架准确植入口部者96.7%(29例/30例),支架近段轻度凸出的只有1例(3.3%)。没有发生严重并发症。结论:结果说明Szabo技术用于冠状动脉口部病变PCI成功率很高,是安全和可行的,值得推广。杨胜利 刘惠亮 Aaron Wong Jack Tan 刘英 张蛟 LIM Soo Teik Paul Chiam Stanley Chia Koh Tian Hai Philip Wong 2011心血管康复医学杂志2011,20,1:3
5A review of computational tools for design and reconstruction of metabolic pathways显示文摘Metabolic pathways reflect an organism's chemical repertoire and hence their elucidation and design have been a primary goal in metabolic engineering.Various computational methods have been developed to design novel metabolic pathways while taking into account several prerequisites such as pathway stoichiometry,thermodynamics,host compatibility,and enzyme availability.The choice of the method is often determined by the nature of the metabolites of interest and preferred host organism,along with computational complexity and availability of software tools.In this paper,we review different computational approaches used to design metabolic pathways based on the reaction network representation of the database(i.e.,graph or stoichiometric matrix)and the search algorithm(i.e.,graph search,flux balance analysis,or retrosynthetic search).We also put forth a systematic workflow that can be implemented in projects requiring pathway design and highlight current limitations and obstacles in computational pathway design.Lin Wang Satyakam Dash Chiam Yu Ng Costas D.Maranas 2017Synthetic and Systems Biotechnology2017,2,4:3
6Prediction of rockhead using a hybrid N-XGBoost machine learning framework显示文摘The spatial information of rockhead is crucial for the design and construction of tunneling or underground excavation.Although the conventional site investigation methods(i.e.borehole drilling) could provide local engineering geological information,the accurate prediction of the rockhead position with limited borehole data is still challenging due to its spatial variation and great uncertainties involved.With the development of computer science,machine learning(ML) has been proved to be a promising way to avoid subjective judgments by human beings and to establish complex relationships with mega data automatically.However,few studies have been reported on the adoption of ML models for the prediction of the rockhead position.In this paper,we proposed a robust probabilistic ML model for predicting the rockhead distribution using the spatial geographic information.The framework of the natural gradient boosting(NGBoost) algorithm combined with the extreme gradient boosting(XGBoost)is used as the basic learner.The XGBoost model was also compared with some other ML models such as the gradient boosting regression tree(GBRT),the light gradient boosting machine(LightGBM),the multivariate linear regression(MLR),the artificial neural network(ANN),and the support vector machine(SVM).The results demonstrate that the XGBoost algorithm,the core algorithm of the probabilistic NXGBoost model,outperformed the other conventional ML models with a coefficient of determination(R2)of 0.89 and a root mean squared error(RMSE) of 5.8 m for the prediction of rockhead position based on limited borehole data.The probabilistic N-XGBoost model not only achieved a higher prediction accuracy,but also provided a predictive estimation of the uncertainty.Thus,the proposed N-XGBoost probabilistic model has the potential to be used as a reliable and effective ML algorithm for the prediction of rockhead position in rock and geotechnical engineering.Xing Zhu Jian Chu Kangda Wang Shifan Wu Wei Yan Kiefer Chiam 2021Journal of Rock Mechanics and Geotechnical Engineering2021,13,6:3
