关键词： 功能性纺织品   稀土   基体标准样品   电感耦合等离子体质谱法  

摘要： 基于功能性纺织品中稀土含量基体标准样品(FT-RE-MRM)的应用,结合电感耦合等离子体质谱法(ICP-MS),建立了用于行业标准SN/T 5288—2022的验证方法。该方法的标准曲线线性相关系数在0.999 4以上,检出限在0.002~0.690 mg/kg,精密度均小于3.63%,回收率在80.3%~94.8%。采用Cochran检验法对8家协同验证机构返回的测定数据进行统计分析,统计量值C均小于检验临界值C(0.05,8,6),表明返回的数据无离群值。计算方法的重复性标准差(Sr)和再现性标准差(SR)分别为:0.004 76、0.006 73、0.003 86、0.005 40、0.007 54、0.004 63,表明该方法的准确度和精密度较高、重复性和再现性良好,适用于纺织品中稀土含量测试标准的验证。

关键词： 纺织品质量检测   QT   TCP/IP   智能分析算法   MySQL   AES  

摘要： 文章设计了一套基于QT与智能技术搭建的纺织品质量智能监控系统。该系统通过传输控制协议/网际协议(transmission control protocol/internet protocol,TCP/IP)技术实时采集摄像头图像数据,引入智能算法对图像数据进行缺陷检测,并采集图片中标准检测结果后展示在预览视图中;同时采用MYSQL数据库存储检测记录,便于历史数据查询模块进行数据检索,增强质量追溯能力。系统还具备人员管理能力,支持人员录入,并采用高级加密标准(advanced encryption standard, AES)加密方式保障人员信息安全,防止信息丢失与盗用。该系统有效提高了纺织品的检测效率和准确性,降低了人工误差率和劳动强度,同时注重信息安全,为纺织行业的智能化转型提供有益参考。

摘要： 习近平总书记2023年在黑龙江省考察时提出要“整合科技创新资源,引领发展战略性新兴产业和未来产业,加快形成新质生产力”,强调“要以科技创新推动产业创新发展新质生产力。”功以才成,业由才广。创新驱动本质上是人才驱动,而青年人才是国家战略人才的核心力量,引导青年创新、发挥青年作用则是培育发展新质生产力的关键着力点。近年来,国网长沙供电公司(以下简称长沙公司)充分发挥团组织“三力”(引领力、组织力、服务力)作用,牢牢把握锻造能源领域国家战略科技力量、打造新型电力系统建设主力军的定位,积极推动创新赋能跨越行动落地、落实,加强人才梯队建设。

关键词： Coronary artery disease   High risk percutaneous intervention   Mechanical circulatory support   ACT   activated clotting time   AMI   acute myocardial infarction   CAD   coronary artery disease   HR-PCI   high risk percutaneous coronary intervention   IABP   Intra-aortic balloon pump   MCS   mechanical circulatory support   LV   left ventricle   PAC   pulmonary artery catheter   VAD   ventricular assist device   VA-ECMO   veno-arterial extracorporeal membrane oxygenation  

摘要： As the field of percutaneous coronary intervention grows in volume, expertise, and available tools, interventional cardiologists are increasingly performing more complex and higher-risk coronary artery procedures. Mechanical circulatory support devices, previously used only in urgent situations, are now being utilized as supplementary tools to enhance outcomes in elective complex cases. This shift has sparked significant discussions about patient and device selection, as well as the potential risks involved. In this article, we explore the various devices and their distinct features. Additionally, we also introduce algorithms for device selection, placement and weaning to help guide physicians during their care for their high-risk PCI patients.

关键词： Editable CAD models   Parametric modeling   CAD model reconstruction   Deep neural networks  

摘要： This paper introduces a novel framework capable of reconstructing editable parametric CAD models from dumb B-Rep models. First, each B-Rep model is represented with a network-friendly formalism based on UV-graph, which is then used as input of eCAD-Net, the new deep neural network-based algorithm that predicts feature-based CAD modeling sequences from the graph. Then, the sequences are scaled and fine-tuned using a feature matching algorithm that retrieves the exact parameter values from the input dumb CAD model. The output sequences are then converted in a series of CAD modeling operations to create an editable parametric CAD model in any CAD modeler. A cleaned dataset is used to learn and validate the proposed approach, and is provided with the article. The experimental results show that our approach outperforms existing methods on such reconstruction tasks, and it outputs editable parametric CAD models compatible with existing CAD modelers and ready for use in downstream engineering applications.

摘要： 随着建筑行业的发展,建筑装饰工程技术的教学越发受到重视,学生学习建筑装饰技术,不仅能加深对建筑知识的认识,还能迎合社会发展需求,成为新时代所需求的人才。但在现阶段教学中,建筑装饰CAD制图教学存在着诸多的问题,侧重理论教学忽视实践教学,严重影响了学生的学习进度,亟须对已有的教学模式进行革新。“教学做”一体化教学模式侧重理论与实践相结合,能将抽象的课程内容具体化,调动学生学习积极性,提高学生的学习效率。鉴于此,研究对建筑装饰CAD制图“教学做”一体化教学模式进行探析,旨在革新课程,培养出德才与理实兼备的优质人才。

摘要： As early as 2012, a review of the literature showed that the prevalence of CAM in cardiac patients ranged from 4% to 61% (1). In 2022, the American Heart Association alerted physicians to the need to communicate with patients on this subject (2) In France, few studies have dealt with in this subject.
