After hundreds of years of technological revolution and rapid development, humanity has reached a moment of crisis in its relationship with nature [1]. To find better solutions to address global challenges, holistic thinking is required to integrate environmental goals with human activities. Some of these approaches include sustainable development (SD), the planetary boundaries (PB) and, in China,ecological civilization (EC) based on the unity of nature and man (UNM)[2].

In order to develop a novel method of visualizing possible Ca2＋ signaling during the early differentiation of hESCs into cardi- omyocytes and avoid some of the inherent problems associated with using fluorescent reporters, we expressed the biolumines- cent Ca2＋ reporter, apo-aequorin, in HES2 cells and then reconstituted active holo-aequorin by incubation withf-coelenterazine. The temporal nature of the Ca2＋ signals generated by the holo-f-aequorin-expressing HES2 cells during the earliest stages of differentiation into cardiomyocytes was then investigated. Our data show that no endogenous Ca2＋ transients （generated by re- lease from intracellular stores） were detected in 1-12-day-old cardiospheres but transients were generated in cardiospheres following stimulation with KC1 or CaC12, indicating that holo-f-aequorin was functional in these cells. Furthermore, following the addition of exogenous ATP, an inositol trisphosphate receptor （IP3R） agonist, small Ca2＋transients were generated from day 1 onward. That ATP was inducing Ca2＋ release from functional IP3Rs was demonstrated by treatment with 2-APB, a known IP3R antagonist. In contrast, following treatment with caffeine, a ryanodine receptor （RyR） agonist, a minima/Ca2＋ response was observed at day 8 of differentiation only. Thus, our data indicate that unlike RyRs, IP3Rs are present and continually functional at these early stages of cardiomyocyte differentiation.

基于连续介质损伤力学理论,以环氧沥青混凝土的疲劳开裂过程为研究对象,建立了梯度增强的非局部损伤模型用于表征材料的疲劳损伤,并进行有限单元数值格式化;利用FEAP有限元软件仿真分析了环氧沥青混凝土在不同温度(10℃、20℃、30℃)、加载应变与饱水状态下小梁试件的四点弯曲疲劳试验。室内疲劳试验结果与仿真结果具有很好的一致性,表明所构建的梯度增强非局部损伤模型具有很好的可靠性。通过疲劳试验数据,回归拟合出不同温度与饱水状态下的环氧沥青混凝土的疲劳损伤参数,为环氧沥青混凝土材料在路面结构中的疲劳特性研究提供了基础材料参数。研究成果为沥青混凝土类材料的疲劳特性研究与性能设计提供了依据与借鉴。
