This researc. advoc.tes for the c.nstruc.ion of c.imate c.ange Haven c.mmunities ac.oss the Appalac.ian Region. The proposed development plan c.n be extended to the northern tier states ac.oss the US and also to the northern and mountainous regions of Europe and Asia. We present an analogy to the earlier c.imate c.ange period of the Last Glac.al Maximum/“Ic. Age” in whic. these same northern regions of the planet were c.vered in ic. sheets making them uninhabitable for most humans and many plant and animal spec.es. In some signific.nt ways, the Ic. Age sc.nario c.n be a reverse-model for our c.rrent c.imate c.isis. We also advoc.te strongly for the prevention of upsc.le real estate development projec.s in these same regions of the globe, as these will forec.ose the possibility of safely sheltering the millions of persons who will be displac.d by c.imate c.ange over the next 5 to 10 years.

The disc.very and synthesis of MnBi2Te4in 2013 initially garnered little attention [1]. Yet, the revelation of its topologic.l properties in 2019 [2–6] sparked a surge of researc. into the MnBiTe family. These extensive studies are primarily driven by two objec.ives:the realization of a high-temperature quantum anomalous Hall effec. （QAHE） and the exploration of exotic.phases born from the interplay of topologic.l and magnetic.orders,

一种流行的减充血剂其实是无效的,最近披露的这一消息暴露了美国FDA监管存在明显问题。2005年,美国联邦法律迫使全美的零售商将伪麻黄碱(商品名Sudafed)从非处方药中移除,以打击不法分子使用该成分制造甲基苯丙胺(结晶形态俗称“冰毒”)。伪麻黄碱是一种减充血剂,这类成分能让血管收缩,缓解组织充血、水肿和黏液分泌,进而改善鼻塞等症状。
