| 2 | Examining the effect of adverse geological conditions on jamming of a single shielded TBM in Uluabat tunnel using numerical modeling显示文摘Severe shield jamming events have been reported during excavation of Uluabat tunnel through adverse geological conditions, which resulted in several stoppages at advancing a single shielded tunnel boring machine(TBM). To study the jamming mechanism, three-dimensional(3D) simulation of the machine and surrounding ground was implemented using the finite difference code FLAC3D. Numerical analyses were performed for three sections along the tunnel with a higher risk for entrapment due to the combination of overburden and geological conditions. The computational results including longitudinal displacement contours and ground pressure profiles around the shield allow a better understanding of ground behavior within the excavation. Furthermore, they allow realistically assessing the impact of adverse geological conditions on shield jamming. The calculated thrust forces, which are required to move the machine forward, are in good agreement with field observations and measurements. It also proves that the numerical analysis can effectively be used for evaluating the effect of adverse geological environment on TBM entrapments and can be applied to prediction of loads on the shield and preestimating of the required thrust force during excavation through adverse ground conditions. | Rohola Hasanpour Jürgen Schmitt Yilmaz Ozcelik Jamal Rostami | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，6： | 8 |
| 3 | Development of ecoregion-based merchantable volume systems for Pinus brutia Ten. and Pinus nigra Arnold. in southern Turkey显示文摘Estimating individual tree volume is one of the essential building blocks in forest growth and yield models.Ecologically based taper equations provide accurate volume predictions and allow classification by merchantable sizes, assisting in sustainable forest management.In the present study, ecoregion-based compatible volume systems for brutian pine and black pine in the three ecoregions of southern Turkey were developed. Several well-known taper functions were evaluated. A secondorder continuous-time autoregressive error structure was used to correct the inherent autocorrelation in the hierarchical data, allowing the model to be applied to irregularly spaced and unbalanced data. The compatible segmented model of Fang et al.(For Sci 46:1–12, 2000) best described the experimental data. It is therefore recommended for estimating diameter at a specific height, height to a specific diameter, merchantable volume, and total volume for the three ecoregions and two species analyzed. The nonlinearextra sum of squares method indicated differences in ecoregion and tree-specific taper functions. A different taper function should therefore be used for each pine species and ecoregion in southern Turkey. Using ecoregionspecific taper equations allows making more robust estimations and, therefore, will enhance the accuracy of diameter at different heights and volume predictions. | Ramazan Ozcelik Yasin Karatepe Nevzat Gurlevik Isabel Canellas Felipe Crecente-Campo | 2016 | Journal of Forestry Research2016，27，1： | 4 |

| 5 | Colorectal stenting for palliation and as a bridge to surgery:A 5-year follow-up study显示文摘AIM: To evaluate the long-term effectiveness of colonic stents in colorectal tumors causing large bowel obstruction.METHODS: We retrospectively analyzed data from 49 patients with colorectal cancer who had undergone colorectal stent placement between January 2008 and January 2013. Patients' symptoms,characteristics and clinicopathological data were obtained by reviewing medical records. The obstruction was diagnosed clinically and radiologically. Histopathological diagnosis was achieved endoscopically. Technical success rate(TSR)was defined as the ratio of patients with correctly placed SEMS upon stent deployment across the entire stricture length to total number of patients. Clinical success rate(CSR) was defined as the ratio of patients with technical success and successful maintenance of stent function before elective surgery(regardless of number of SEMS deployed) to total number of patients. The surgical success rate(SSR) of colorectal stent as a bridge to surgery was defined as the ratio of patients with successful surgical procedures. Unsuccessful surgical outcomes were defined as being due to insufficient colonic decompression. The technical,clinical,surgical success rates and complications after stenting were assessed.RESULTS: The median age of patients was 64(36 to 89). 44.9% of patients were male and 55.1% were female. Eighteen patients had the obstruction located in the rectum,15 patients in the rectosigmoid region,10 patients in the sigmoid region,and 6 patients had a tumor causing obstruction in the proximal colon. Each patient was categorized pathologically as stage 2(32.7%,16 patients) or stage 3(42.9%,21 patients) and 12 patients(24.4%) had metastatic disease. None of the patients received chemotherapy before stenting. Stenting was undertaken in 37 patients as a bridge to surgery,and in 12 patients stents were used for palliation. Median time to surgery after stenting was 30 ± 91.9 d. All surgery was completed in one single operation and thus no colostomy with stoma was needed. The median overall survival rate of patients with stage 2-3 colorectal cancer was 53.1 mo and stage 4 was 37.1 mo(P = 0.04). Metastatic colorectal patients who were treated palliatively with stents had backbone chemotherapy with oxaliplatin and/or irinotecan-based regimens plus antiangiogenic therapies,especially bevacizumab. Resolution of the obstruction and clinical improvement was achieved in all patients. The technical,clinical and surgical success rates were 95.9%,100% and 94.6%,respectively.CONCLUSION: The efficacy and safety of colonic stents was demonstrated both as a bridge to surgery and for palliative decompression. In addition,results emphasize the importance of the skills of the endoscopist in colonic stenting. | Baris Bayraktar Ibrahim Ali Ozemir Umut Kefeli Gokhan Demiral Julide Sagiro?lu Onur Bayraktar Gupse Adali Alp Ozcelik Osman Baran Tortum | 2015 | World Journal of Gastroenterology2015，21，31： | 3 |

| 7 | Acoustofluidic separation of cells andparticles显示文摘Acoustofluidics,the integration of acoustics and microfluidics,is a rapidly growing research field that is addressing challenges in biology,medicine,chemistry,engineering,and physics.In particular,acoustofluidic separation of biological targets from complex fluids has proven to be a powerful tool due to the label-free,biocompatible,and contact-free nature of the technology.By carefully designing and tuning the applied acoustic field,cells and other bioparticles can be isolated with high yield,purity,and biocompatibility.Recent advances in acoustofluidics,such as the development of automated,point-of-care devices for isolating sub-micron bioparticles,address many of the limitations of conventional separation tools.More importantly,advances in the research lab are quickly being adopted to solve clinical problems.In this review article,we discuss working principles of acoustofluidic separation,compare different approaches of acoustofluidic separation,and provide a synopsis of how it is being applied in both traditional applications,such as blood component separation,cell washing,and fluorescence activated cell sorting,as well as emerging applications,including circulating tumor cell and exosome isolation. | Mengxi Wu Adem Ozcelik Joseph Rufo Zeyu Wang Rui Fang Tony Jun Huang | 2019 | Microsystems & Nanoengineering2019，5，1： | 2 |
