Abstract Background Nearly half of bronchiectasis patients receiving bronchial artery embolization (BAE) still have recurrent hemoptysis, which may be life-threatening. Worse still, the underlying risk factors recurrence remain unknown. Methods A retrospective cohort was conducted with idiopathic who received BAE from 2015 to 2019 at eight centers. Patients were followed up for least 24 months post BAE. Based on outcomes hemoptysis and severe a Cox regression model used identify recurrence....
Background: This study aimed to explore the efficacy and safety of drug-eluting beads bronchial arterial chemoembolization (DEB-BACE) compared with conventional (cBACE) in lung cancer patients hemoptysis. Materials & methods: Thirty-six hemoptysis treated by DEB-BACE or cBACE were retrospectively analyzed. Results: Technical success BACE clinical treatment no different between (both p > 0.050), whereas achieved increased total response (p = 0.021), objective rate 0.035) prolonged...
A chamfering method is proposed in order to improve processing accuracy and efficiency of tooth crest spiral bevel gear. Coordinates discrete points upper lower edges surface are calculated based on the mathematical model face cone. Distances between center ball end milling cutter set equal radius cutter, tool path generated by particle swarm algorithm solving, both sides can be chamfered simultaneously ensure efficiency. Direction angle axis relationship direction contact positions surface....
Abstract Fly cutting is widely used in manufacturing of large-scale, high-precision optical components. However, the discontinuity fly machining leads to significant relative vibrations between tool and workpiece. The process generates periodic waves along direction, which will deteriorate wavefront characteristics Based on dynamics, this paper proposes a direct integration method predict waviness error machined surface. force model established. multi-mode spindle-tool system are measured by...
The advent of programmable vector graphics on the web has major implication for GIS. Macromedia Flash as a plug in possesses many characteristics. However, is more suitable designer not programmer. Especially temporal Furthermore, takes much time to generate SWF files. Therefore, Flex an alternative. It better messaging infrastructure and data synchronization. paper provides method display urban change using 4.6. Another attraction project use Web Service which link database. result shows...
Climate change and global environment has become one of the most popular topics. Our understanding Earth is expanding for geoinformation technological developments. Scientists, developers many others have used technology to better understand change. Remotely-sensed radiative transfer models, quantitative retrieval theory, data acquisition assimilation methods are in research. The paper introduce advance these four aspects. Geographic information system offers a means assess, analyze, plan...
A method of solving contact trajectory boundary is developed for spiral bevel gear. Tooth surfaces pinion and gear are projected to axial cross section based on rotation transformation, vector operation used distinguish whether point belongs tooth surface or not. Distances between every calculated, if the minimum distance less than preset value, this considered be boundary. Starting from initial TCA, approaches by adaptive step size, when currently size greater value last as new point,...
An improved algorithm of tooth contact analysis (TCA) is proposed to overcome the deficiency current TCA for hypoid gear. The key improvement introduce proportional coefficients length and height in TCA. solution domain nonlinear equations limited range surface by variable substitution. By analyzing positions which boundary points possibly appear on axial section, values corresponding are obtained. Boundary trace computed with particle swarm conjugate gradient method, distributed solved...
