摘要： In recent years, powered airships have been considered promising alternatives for high-altitude, long-endurance missions. To address the issues of high computational costs, insufficient consideration of engineering constraints, and disconnect from manufacturing validation in existing global optimisation methods, a local optimal multidisciplinary design optimisation (MDO) framework based on genetic algorithms (GAs) is proposed in this study. In this framework, an industry-friendly lightweight parametric model (seven-segment Bézier) is innovatively used for parametric modelling of the airship fuselage, which enables precise control over critical geometric features. By establishing a multiobjective fitness function with adjustable weights and incorporating nonlinear constraints, the multi-objective genetic algorithm (MOGA) is used to efficiently search for locally Pareto optimal solutions within the feasible engineering domain. The optimised results are reconstructed into a three-dimensional model in SolidWorks and validated rigorously through a high-fidelity virtual flight test platform. Compared with the baseline design, the optimised scheme achieves a significant increase in volume of 29.8 % and 9.5 %, a reduction in the drag coefficient of 7.2 % and 4.3 %, and an improvement in energy efficiency of 26.4 % and 4.8 % while maintaining the structural stress threshold. Sensitivity analysis and Monte Carlo simulations further confirm the robustness of the solution to manufacturing tolerances. The integrated framework established in this study, which combines parametric modelling with GA local optimisation and CAD/CFD validation, provides a computationally efficient, reliable, and manufacturable solution for the engineering design of stratospheric airships, thereby significantly advancing the transition from theoretical optimisation to practical application.

摘要： Severe aortic stenosis (AS) often coexists with coronary artery disease (CAD), present in about 50 % of patients undergoing valve intervention. Surgical aortic valve replacement (SAVR) with coronary artery bypass graft (CABG) has been the traditional standard, providing revascularization and durability, whereas transcatheter aortic valve replacement (TAVR) with percutaneous coronary intervention (PCI) offers a less invasive option. PCI + TAVR may lower perioperative risk, but SAVR + CABG may confer superior survival, with conflicting evidence.

摘要： Hypertension affects over 116 million adults in the United States and >1 billion globally, substantially contributing to cardiovascular morbidity. Herbal therapies have emerged as potential complementary treatments for blood pressure management. To the best of our knowledge, this study is the first systematic review with network meta-analysis (NMA) aimed at ranking the most effective herbal therapies for lowering blood pressure.

摘要： 为量化评估家庭洗涤过程中纤维微塑料的排放情况及其空间分布特征,研究基于全球纺织品消费数据,结合洗涤过程微塑料释放因子,通过构建释放及迁移通量模型,评估了不同国家和地区的洗涤行为与污水处理水平差异对纤维微塑料释放特征的影响.模型结果显示,2022年全球范围内纤维微塑料排放总量约为229.88万t,其中印度、中国和美国为排放量最高的三个国家,排放量分别为62.45万t、47.14万t和33.28万t.经污水处理厂处理后,不同地区的微塑料去除效率差异明显,北美洲污水系统对微塑料的去除率最高,达78%,相比之下,亚洲和非洲地区去除水平低于全球平均水平.最终,未被截留的纤维微塑料通过河流进入海洋,其中恒河(1.65万t)、长江(1.24万t)和印度河(0.51万t)为排入海洋纤维微塑料量最多的三条河流.
