关键词： Complete revascularization   Coronary artery bypass grafting   Inferior Mini-sternotomy   Minimally invasive surgery   Multivessel disease  

摘要： A critical barrier to advancing minimally invasive coronary artery bypass grafting (CABG) lies in achieving complete revascularization (CR) in multivessel disease (MVD) patients. Contrasting with other minimally invasive approaches, inferior mini-sternotomy (IMS) offers distinct advantages in addressing complex multivessel disease and concomitant cardiac pathologies, which is similar to conventional median sternotomy (CMS) approach. The primary aim of this trial is to test the hypothesis that the CR rates of IMS-CABG could approximate that of CMS-CABG in MVD patients.

关键词： Surface parameterization   Conformal mapping   CAD models   PHT-splines  

摘要： In practical engineering applications, the application of coatings designed from Computer-Aided Design (CAD) models (e.g., stealth coatings for aircraft) onto three-dimensional components must take into account the material’s ductility limits. Conventional mesh-based conformal parameterization, which directly maps surface meshes to planar domains, often results in uncontrolled distortion, and the quality of the mapping is heavily influenced by mesh density and quality. In contrast, we propose a novel Polynomial splines over Hierarchical T-meshes (PHT-splines) based conformal parameterization that achieves globally $C^1$-continuous mappings with controlled distortion through adaptive refinement. This adaptive mechanism incorporates dedicated conformal metrics to suppress excessive mapping distortion observed in numerical tests and enables direct texture coordinate localization. Experimental results demonstrate the superior performance of our approach in industrial CAD applications such as texture mapping and remeshing, successfully bridging the gap between theoretical conformal geometry and practical engineering requirements.

关键词： adhesive interfaces   CAD/CAM inlays   deep margin elevation   marginal fit   resin composites   SEM   thermomechanical aging  

摘要： Objective This in vitro study evaluated the effects of composite material type, margin design (deep margin elevation vs. control and thermomechanical aging on the marginal gap of CAD/CAM inlay restorations. Materials and Methods Standardized mesio-occluso-distal (MOD) inlay cavities were prepared in extracted human molars, with mesial margins located at the cemento-enamel junction (control) and distal margins extended 2 mm apical to the CEJ and elevated using three resin composite materials (bulk-fill, packable, and flowable). CAD/CAM inlays were fabricated and luted. Marginal gap values were measured using scanning electron microscopy at baseline and after thermomechanical aging simulating 1 year of clinical service. Data were analyzed using mixed repeated-measures ANOVA to evaluate the effects of material type, margin design, aging condition, and their interactions (alpha = 0.05). Results Thermomechanical aging significantly increased marginal gap values (p < 0.001). Margin design showed a significant effect (p = 0.015 whereas the main effect of material type was not statistically significant (p = 0.205). Significant interactions were observed between material type and margin design (p = 0.008) and among material type, margin design, and aging condition (p < 0.001). Conclusions Within the limitations of this current study, thermomechanical aging significantly increased marginal gap values of CAD/CAM inlays. Material type alone did not show a significant main effect on marginal gap. However, significant interaction effects were observed between material type and deep margin elevation, as well as between material type and aging condition.

摘要： 通过对纺织品标准GB/T 32008—2015《纺织品色牢度试验耐贮存色牢度》进行系统研究，设定测试条件：温度50℃、相对湿度80%、时间48 h,采用不同成分的8种贴衬织物作为浅色面料，分别与深色样品相贴合，形成组合试样，采用汗渍色牢度仪试验装置，放置在恒温恒湿装置中进行试验，并对不同贴衬织物之间在贮存过程中染料迁移能力的差异进行比较分析，得出不同贴衬织物贮存沾色能力的强弱顺序为丝、锦纶>棉>羊毛>苎麻>黏纤>聚酯>腈纶，研究得出织物的结构和表面特性是影响其耐贮存沾色能力的关键因素。

关键词： 纺织品   防蚊性能   白纹伊蚊   驱避测试器   影响因素  

摘要： 为探究驱避测试器法检测纺织品防蚊性能的影响因素，本研究以白纹伊蚊为试验蚊虫、标准棉贴衬织物为对照样，结合50份防蚊整理纺织品试样，依据GB/T 30126—2013开展试验，分析驱避测试器孔位、志愿者特征及纺织品颜色明度对检测结果的作用规律。结果表明，驱避测试器孔位是极显著影响因素，4号孔位蚊虫停留数最高，孔位组合直接决定驱避率结果；志愿者个体生理差异是检测结果重复性差的主要因素，左右手、性别特征为次要干扰因素；纺织品颜色明度对驱避效果影响显著，低明度织物易吸引蚊虫，防蚊级别多在C级以下，高明度织物更易检出高等级防蚊效果。研究明确了各因素的干扰机制与作用程度，提出了标准化检测的管控措施，为完善纺织品防蚊检测标准、指导防蚊纺织品研发生产提供了科学依据。
