Building a good supply network has a competitive advantage in every part of business. However, people rarely know the principles from which supply chain with complex organizational structure and function arise and develop. In this paper, we develop an evolving supply network model by using complex network theory. We mainly consider three kinds of firms＇ behaviors： entering of new firms, adding new relationships and rewiring of relationships among firms. By analyzing the statistical characteristics of the evolutionary dynamics of supply network, we find that the degree distribution follows a power-law distribution. Therefore, a supply network is a scale-free network where few but significant firms have lots of connections （called ＂hub＂ or core firm）, while most firms have few connections. These results are consistent with the results in empirical researches, which will be very useful for designing a robust and effective supply network.

废旧产品分类回收作为资源分类依据和回收处理的前置环节,是提高资源利用效率的重要途径。为分析政府奖惩机制对废旧产品分类回收效果及协调机制影响,本文基于废旧产品分类回收分别构建政府两种奖惩措施下回收商与处理商博弈模型,研究主要得到:(1)政府基于废旧产品回收量采取奖惩措施并不总是对回收商和处理商分类回收行为有利;(2)政府基于分类回收努力程度对回收商采取奖惩措施可以有效提高单位委托回收价格和分类回收努力程度,增加废旧产品回收量和处理商收益,但是政府对处理商采取奖惩措施不能有效影响处理商和回收商运营决策;(3)当分类回收努力程度奖惩力度大于某一阈值时,政府基于分类回收努力程度对回收商采取奖惩措施可以实现回收商和处理商双赢;(4)通过委托回收价格契约和成本分摊-收益共享协调契约可以使回收数量、分类回收努力程度以及回收渠道整体收益达到集中决策时的效果。

Economic feasibility is crucial for achieving the carbon neutrality target. However, current integrated assessments often underestimate the economic impacts of mitigation policies due to the lack of consideration of their economic benefits. This study integrates a warming-labour productivity model with a typical integrated assessment model using shared socioeconomic pathways. It simulates China's economic development and carbon emission levels under both baseline and carbon-neutral policy scenarios, evaluating the economic costs and benefits of emission reduction policies aimed at achieving carbon neutrality. These findings reveal the following:(1) The economic costs of emission reduction policies are projected to peak between 2050 and 2060, ranging from 0.41% to 9.37% of total GDP in the baseline scenario, primarily due to increased energy prices and R&D investments. These costs are expected to decline rapidly after 2070.(2) China's carbon-neutral policies will mitigate global warming, with the economic benefits of mitigation projected to reach 5.65% to 17.24% of China's total GDP by 2100.(3) Lowcarbon scenarios SSP1 and SSP4 could significantly reduce initial economic costs and advance the onset of net economic gains to 2060. This integrated assessment confirms that China's carbon neutrality target offers substantial net economic benefits in the long term. To minimize initial economic costs, efforts should focus on enhancing consumption-side transitions, upgrading lowcarbon technologies, and adopting new energy sources.

Five tectonic modes of mantle convection are obtained and analyzed with three-dimensional numerical models in a spherical shell domain. The five tectonic convective modes are non-plate mobile-lid, plate-like mobile-lid, episodic plate-like mobile-lid, episodic stagnant-lid, and stagnant-lid convective modes, respectively. The typical characteristics of these five tectonic modes and their numerical classification criteria based on plateness, mobility, and their standard deviations are presented and discussed. The results show that the yield stress of the lithosphere has profound effects on the tectonic convective *** the gradual increase of yield stress, the tectonic mode of mantle convection changes from one to another sequentially through the aforementioned five modes. Additionally, as the Rayleigh number increases, the range of yield stress for the platelike mobile-lid convective mode decreases, and the dimensionless transition stress between different tectonic modes ***, the dimensional transition stress between the non-plate mobile-lid convective mode and plate-like mobile-lid convective mode increases with the increase of Rayleigh number, but decreases between other tectonic modes. Furthermore, we find that the transition stress between different tectonic modes is inversely proportional to the internal heating rate, with the transition stress decreasing as the internal heating rate increases. The fitting analysis of the transition stress between tectonic modes shows that Earth's current plate tectonics correspond to a lithospheric yield stress of 150–250 MPa, which aligns with the strength of serpentinized mantle rock determined by experimental petrography. If the Archean mantle was 300°C warmer than it is today, then the Earth was in an episodic stagnant-lid convective mode. The tectonic evolution of the Earth's surface is closely related to the lithospheric strength and the process of thermal evolution. If the lithospheric strength w

目的评估临床常用的五种中成药分别联合二甲双胍治疗2型糖尿病(T2DM)的有效性。方法检索PubMed、Web of Science、Cochrane Library、中国知网、万方数据知识服务平台、中国生物医学文献服务系统数据库中,关于六味地黄丸、消渴丸、津力达、参芪降糖颗粒/胶囊/片(简称参芪降糖)、天芪降糖胶囊/颗粒/片(简称天芪降糖)分别联用二甲双胍治疗T2DM的随机对照试验(RCT),文献时间范围为建库至2020年4月10日。进行文献筛选、资料提取并评价纳入研究的偏倚风险后,分别对不同结局指标包括糖化血红蛋白、空腹血糖、总胆固醇、甘油三酯,采用网状Meta分析方法及曲线下累积排序概率面积进行有效性比较及排序。结果最终纳入42项RCT,共包括4356例患者。网状Meta分析结果显示,与二甲双胍比较,六味地黄丸[MD=-0.85,95%CI(-1.08,-0.62)]、消渴丸[MD=-0.76,95%CI(-1.28,-0.25)]、津力达[MD=-1.16,95%CI(-1.59,-0.73)]、参芪降糖[MD=-1.14,95%CI(-1.43,-0.85)]分别联用二甲双胍能有效降低糖化血红蛋白水平(P0.05)。结论五种中成药分别联用二甲双胍对T2DM患者血糖、血脂指标均有不同程度的改善作用,但由于纳入研究质量存在较多方法学问题,建议结合临床具体情况选择用药。
