基于等效刚度的思想,通过设定层合板的属性参数模拟了加筋板结构的力学特性,提出了一种适用于不同截面形状以及布局形式的加筋板总体失稳分析的等效层合板建模方法。利用PATRAN/NASTRAN软件比较了反映实际壁板形状的高精度有限元模型与对应的赋有层合板属性的等效刚度简化模型。对于工程中常见形状的加强筋以及不同布局形式的壁板,2种模型的一阶线性失稳因子基本一致,从而验证了将等效层合板模型用于加筋壁板结构的稳定性分析可以满足工程精度要求,并显著提高了计算效率。

Background: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in ***: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in china from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group ***: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [n = 278]vs. 43.7% [n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1%vs. 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk ***: This study indicated that PCI in patients on dialysis with CAD was significantly assoc

O2O模式是近年来电商运营管理领域的热点问题。针对O2O模式中线上零售商的定价及企业社会责任(corporate social responsibility,CSR)投入策略,考虑由制造商与拥有线下体验店的线上零售商构成的系统,构建消费者预期效用函数,建立两阶段动态博弈模型。分析制造商与线上零售商的最优定价与CSR投入策略,考察CSR投入对消费者购买行为、供需双方定价策略与利润的影响。研究发现:CSR投入有利于提升线上零售商和整合系统的利润,即线上零售商会有动机选择CSR投入策略;CSR投入会导致部分消费者发生渠道迁移行为以及产品需求的降低和产品零售价格的提高,即消费者要为线上零售商CSR行为支付额外的溢价;最后,从制造商的角度,线上零售商的CSR投入策略会给制造商带来负外部性,并激励制造商实施低价策略来降低产品批发价格。

晚清铁路的开通,不仅大大便利了经济活动,更使人们的出行发生了革命性的变化。无铁路的时代,所有远行者都会慨叹“行路难”,有了快捷、舒适的铁路以后,徐世昌等官员的出行,几如家常便饭。徐世昌等官员对铁路的利用,一方面极大便利了政务,他可以随时到北京周边检阅军队、查验铁路工程、考察并改变造币厂的地点,甚至到较远的东三省考察;另一方面与袁世凯的频繁会见,巩固了他与袁世凯的盟友关系。可以说铁路的利用直接影响了晚清政局。进一步,为适应铁路的快节奏,人们必须改变时间观念和生活节奏。因此,铁路的利用改变了官员的政务模式,并改变了人们的生活。
