| 1 | 服役破损叶片的曲面重构及刀路生成方法显示文摘针对常见的边缘破损叶片和顶端破损叶片,研究了其修复加工过程中的破损区域几何重构与刀路生成的方法。利用测量数据点排序、调整,构造叶片截面曲线,采用能量最小化原理对截面曲线进行光顺处理,并提出一种依据曲率将截面曲线对齐的方法。提出了一种基于放样建模的叶片模型几何重构方法,并针对边缘破损叶片与顶端破损叶片,提取破损区域并分别给出zigzag形加工刀路与螺旋形加工刀路的生成方法。不同方法重建叶片曲面质量的对比表明,所提方法能保证曲面的高斯曲率且更贴近其真实变形,验证了所提刀路生成方法的可行性。 | 赵旭升 杨建中 陈吉红 Alexander FRADKOV Oleg GRANICHIN 胡鹏程 | 2019 | 中国机械工程2019，30，24： | 4 |
| 2 | Bleeding with the artificial heart: Gastrointestinal hemorrhage in CF-LVAD patients显示文摘Continuous-flow left ventricular assist devices(CF-LVADs)have significantly improved outcomes for patients with end-stage heart failure when used as a bridge to cardiac transplantation or,more recently,as destination therapy.However,its implantations carries a risk of complications including infection,device malfunction,arrhythmias,right ventricular failure,thromboembolic disease,postoperative and nonsurgical bleeding.A significant number of left ventricular assist devices(LVAD)recipients may experience recurrent gastrointestinal hemorrhage,mainly due to combination of antiplatelet and vitamin K antagonist therapy,activation of fibrinolytic pathway,acquired von Willebrand factor deficiency,and tendency to develop small intestinal angiodysplasias due to increased rotary speed of the pump.Gastrointestinal bleeding in LVAD patients remains a source of increased morbidity including the need for blood transfusions,extended hospital stays,multiple readmissions,and overall mortality.Management of gastrointestinal bleeding in LVAD patients involves multidisciplinary approach in stabilizing the patients,addressing risk factors and performing structured endoluminal evaluation with focus on upper gastrointestinal tract including jejunum to find and eradicate culprit lesion.Medical and procedural intervention is largely successful and universal bleeding cessation occurs in transplanted patients. | Grigoriy E Gurvits Elena Fradkov | 2017 | World Journal of Gastroenterology2017，23，22： | 4 |
