我们对如何监管在运输、短租及其他领域连接平台用户与非正式服务提供者的新型软件平台进行探索。这些平台与以许可、资质、保险为框架的传统监管体系存在紧张关系。一种观点认为,部分监管规则或者已经无法回应市场需求,或者以既得利益者而非平台用户为保护对象。反对者则声称,这些监管规则体现了重要的价值原则,为平台用户及公众权益提供了保障。本文从监管规则何以促进平台经济效率的发挥、实现平台用户及第三人权益保护的视角出发,探讨上述分歧。

脂肪分布也是可遗传的表征并且是独立于总体脂肪含量成为代谢疾病的预测指标。异位脂肪堆积尤其是腹部脂肪沉积会增加代谢性疾病以及心血管疾病的死亡率。评估脂肪分布最简便的指标是腰臀比(WHR)。WHR数值较大意味着更多的腹部脂肪沉积并增加2型糖尿病和心血管疾病的风险。相反,WHR数值较小则意味着较低的2型糖尿病、高血压、脂代谢紊乱风险。之前的GWAS研究已经识别了调整

包装总是承受着一些在运输过程中的损伤,W?hler曲线通常用来确定一个包装系统的机械磨损演变。损伤估算可以用雨流法进行,但应力要求连续记录。然而,进行连续记录是不可能的,所以以全球运输振动的功率谱密度(PSD)为代表进行记录是适合的。本文根据W?hler曲线系统的损伤进行研究。Basquin模型被用来确定系统的机械磨损和机械行为的演化,通过从W?hler曲线中提取Basquinβ系数和常数系统C建立模型。W?hler曲线进一步体现包装系统的数据变化,及其Basquin系数B和系统常数C进行提取。损伤估算所积累的应力循环,利用Palmgren Miner规则进行排列重组,形成规律模型。在本文中,在一个信号中检测到的周期最大峰值,它的最大应力出现概率密度也由一个多元高斯模型体现。协会有相同的统计特性所对应时间的事件,因此这些统计特性可被用来提取谱矩法。此外,损伤方程提出了采用PSD,并由不同的月台幕门损伤方程确定,与振动台的实际持续时间进行比较,得出更精准的结果。
