2Optimization of construction scheme and supporting technology for HJS soft rock tunnel显示文摘For a soft rock tunnel under high stress in jointed and swell soft rock(HJS), two construction schemes pilot-tunneling enlarging excavation and step-by-step excavation were optimized using FLAC2 D, and the deformation effects of the two construction schemes were verified by field tests. Based on engineering geological investigation and mechanical analysis of large deformations, the complex deformation mechanisms of stress expansion and structural deformation of the soft rock tunnel were confirmed,and support countermeasures from the complex deformation mechanism converted to a single type were proposed, and the support parameters were optimized by field tests. These technologies were proved by engineering practice, which produced significant technical and economic benefits.Wang Shuren Li Chunliu Liu Zhaowei Fang Junbo 2014International Journal of Mining Science and Technology2014,24,6:7

4UMBRELLA: user demand privacy preserving framework based on association rules and differential privacy in social networks显示文摘Dear editor,The past several years have witnessed that people deeply rely on online services,such as shopping,transportation,and medical services.At the same time,privacy leakage has been a hot topic in social networks[1,2].Morever,the increasing applications of location based services(LBSs)indeed make our lives more convenient.However,LBSs also lead to significant privacy leakage.On the one hand,location information of a single point is sensitive.On the other hand,location trajec.tories can excavate more sensitive information despite location.In this regard,location privacy-preserving mechanisms have been extensively studied,such as Dunmiy,spatial confusion[3,4],encryption technology[5,6],differential privacy(DP)[7,8]and references therein.Chunliu YAN Ziyi NI Bin CAO Rongxing LU Shaohua WU Qinyu ZHANG 2019Science China(Information Sciences)2019,62,3:2

6Automatic Calcified Plaques Detection in the OCT Pullbacks Using Convolutional Neural Networks显示文摘Background Coronary artery calcification is a well-known marker of atherosclerotic plaque burden.High-resolution intravascular optical coherence tomography(OCT)imaging has shown the potential to characterize the details of coronary calcification in vivo.In routine clinical practice,it is a time-consuming and laborious task for clinicians to review the over 250 images in a single pullback.Besides,the imbalance label distribution within the entire pullbacks is another problem,which could lead to the failure of the classifier model.Given the success of deep learning methods with other imaging modalities,a thorough understanding of calcified plaque detection using Convolutional Neural Networks(CNNs)within pullbacks for future clinical decision was required.Methods All 33 IVOCT clinical pullbacks of 33 patients were taken from Affiliated Drum Tower Hospital,Nanjing University between December 2017 and December 2018.For ground-truth annotation,three trained experts determined the type of plaque that was present in a B-Scan.The experts assigned the labels'no calcified plaque','calcified plaque'for each OCT image.All experts were provided the all images for labeling.The final label was determined based on consensus between the experts,different opinions on the plaque type were resolved by asking the experts for a repetition of their evaluation.Before the implement of algorithm,all OCT images was resized to a resolution of 300×300,which matched the range used with standard architectures in the natural image domain.In the study,we randomly selected 26 pullbacks for training,the remaining data were testing.While,imbalance label distribution within entire pullbacks was great challenge for various CNNs architecture.In order to resolve the problem,we designed the following experiment.First,we fine-tuned twenty different CNNs architecture,including customize CNN architectures and pretrained CNN architectures.Considering the nature of OCT images,customize CNN architectures were designed that the layers were fewer than 25 layers.Then,three with good performance were selected and further deep fine-tuned to train three different models.The difference of CNNs was mainly in the model architecture,such as depth-based residual networks,width-based inception networks.Finally,the three CNN models were used to majority voting,the predicted labels were from the most voting.Areas under the receiver operating characteristic curve(ROC AUC)were used as the evaluation metric for the imbalance label distribution.Results The imbalance label distribution within pullbacks affected both convergence during the training phase and generalization of a CNN model.Different labels of OCT images could be classified with excellent performance by fine tuning parameters of CNN architectures.Overall,we find that our final result performed best with an accuracy of 90%of'calcified plaque'class,which the numbers were less than'no calcified plaque'class in one pullback.Conclusions The obtained results showed that the method is fast and effective to classify calcific plaques with imbalance label distribution in each pullback.The results suggest that the proposed method could be facilitating our understanding of coronary artery calcification in the process of atherosclerosis andhelping guide complex interventional strategies in coronary arteries with superficial calcification.Chunliu He Yifan Yin Jiaqiu Wang Biao Xu Zhiyong Li 2019医用生物力学2019,34,A01:2
7Supersaturated polymeric micelles for oral silybin delivery: the role of the Soluplus–PVPVA complex显示文摘Increasing the degree of supersaturation of drugs and maintaining their proper stability are very important in improving the oral bioavailability of poorly soluble drugs by a supersaturated drug delivery system(SDDS). In this study, we reported a complex system of Soluplus–Copovidone(Soluplus–PVPVA)loaded with the model drug silybin(SLB) that could not only maintain the stability of a supersaturated solution but also effectively promote oral absorption. The antiprecipitation effect of the polymers on SLB was observed using the solvent-shift method. In addition, the effects of the polymers on absorption were detected by cellular uptake and transport experiments. The mechanisms by which the Soluplus–PVPVA complex promotes oral absorption were explored by dynamic light scattering, transmission electron microscopy, fluorescence spectra and isothermal titration calorimetry analyses. Furthermore, a pharmacokinetic study in rats was used to demonstrate the advantages of the Soluplus–PVPVA complex. The results showed that Soluplus and PVPVA spontaneously formed complexes in aqueous solution via the adsorption of PVPVA on the hydrophilichydrophobic interface of the Soluplus micelle, and the Soluplus–PVPVA complex significantly increased the absorption of SLB. In conclusion, the Soluplus–PVPVA complex is a potential SDDS for improving the bioavailability of hydrophobic drugs.Chunliu Zhu Shuang Gong Jinsong Ding Miaorong Yu Ejaj Ahmad Yi Feng Yong Gan 2019Acta Pharmaceutica Sinica B2019,9,1:2
