在新型OTN（光传送网）中,传统的p圈算法在保护效率和资源利用率上有明显的不足,文章针对这一缺点,提出了一种新的改进算法。该算法针对链路双向工作量的差别,通过优先选择跨接链路来提高资源利用率,还能在资源有限的情况下提高保护效率。在泛欧COST239网络上进行了仿真,仿真结果表明:该算法在资源利用率上有明显的提高,在保护效率上也优于传统的p圈算法。

In order to solve the issues of obtaining the basic topographic data in the comprehensive management planning and design of small watershed, we established the Qilongwan small watershed digital twin baseplate model, including SAR satellite remote sensing, tilt photography and LiDAR. We extracted the longitudinal section of the main channel, the boundary of the two terrace plots, and the depression degree of the 10 woodland sample areas in the model, and then compared the accuracy test with the manual interpretation or measured results. The results show that the extraction accuracy of lidar as the data source, tilt photography as the second of the data source, and SAR satellite re- mote sensing as the data source. In view of the advantages and disadvantages of the three data source models, the multi-source data fusion can be carried out according to the actual work needs to improve the application effect of digital twin technology in the planning and design of small watershed comprehensive management. In the small watershed of Qilongwan, the shikan terrace plot is selected for SAR satellite remote sensing and tilt photography data fusion, and the popular science exhibition hall is selected for tilt photography and lidar data fusion, which has achieved good results.

Objective To evaluate the relationship between platelet activity as measured by thrombelastography（TEG） and interventional procedure and periprocedural myocardial injury（PMI） in patients undergoing selective percutaneous coronary intervention （PCI）. Methods The data was collected from 378 patients of coronary heart disease（CHD）who received coronary arteriography（CAG） and stent implantation in Department of Cardiology，Zhongshan Hospital from Jan to Oct，2017. After 12 hours of dual anti-platelet drug load，platelet reaction of the patients was measured by TEG. The number and length of stents in PCI were counted. Thrombin-induced maximum amplitude of clot strength （MAThrombin）reflected the intrinsic platelet activity，AA% and ADP% reflected the platelet inhibition rate of aspirin and clopidogrel，respectively. Results A total of 98 patients（25.9%）occurred PMI. Compared with the non-PMI group，the ADP% in PMI group was poor（48.5%±24.0% vs. 54.7%±25.9%，P= 0.038）. However，there was no significant difference between the two groups in the inhibitory rate of MAThrombin and AA%.Multi-factor Logistic regression revealed that age（OR=1.041，95%CI：1.013-1.071， P=0.004），number of stents ≥3（OR=3.009，95%CI：1.590-5.694，P=0.001），length of stents≥40 mm （OR=2.687，95%CI：1.436-5.030，P=0.002） and ADP% （OR=0.990，95%CI：0.980-0.999，P=0.040） are independent predictors of PMI occurrence. Conclusion PMI is a result mediated by multiple factors in patients undergoing selective coronary stenting. In addition to age，the number and length of stents implanted，the clopidogrel resistance were also independent risk factors for the occurrence of PMI. [ABSTRACT FROM AUTHOR]

Platelets regulate angiogenesis involving to a wide range of processes including tissue repair, wound healing, collateral circulation establishment, and blood/lymphatic vessel separation during embryonic development period under physical condition. Pathological angiogenesis related closely to tumor metastasis, atherosclerosis and diabetic retinopathy. The role of platelets in angiogenesis indicates that platelets regulate the procedure through a complex and accurate signaling network, exerting effects by secreting platelet pro-/anti-angiogenesis proteins and phospholipids, interacting with endothelial progenitor cells (EPCs), releasing platele microparticles (PMPs), etc. In this review we summarize the roles and possible mechanisms of the angiogenesis regulation by blood platelets, discuss some of the hypotheses that may explain how platelets regulate angiogenesis, as well as the current clinical application about platelet-derived products. As a result, investigating into the role blood platelets playing in the regulation of angiogenesis may provide promising pharmaceutical targets and new clinical treatment strategies for diseases on the pathological basis of ischemia and abnormal vessels remolding.
