美国按揭贷款利率的上升给春季房地产市场的传统销售旺季蒙上了阴影,美国成屋签约销售指数在4月份跌至四年来的最低点,那时正深陷新冠疫情危机。 周四,美国房地产经纪人协会(NAR)公布的数据显示,美国4月成屋签约销售指数环比大跌7.7%,至72.3,创2020年4月份以来新低。4月该指数的月度跌幅超过媒体调查的所有经济学家的...
欧美和日本等亚洲制造业明显降温,重燃市场对鹰派央行政策令经济陷入衰退的恐慌。美国7月ISM制造业指数降至2020年6月以来最低,新订单分项指数连续两个月萎缩,但原材料价格支付指数降幅创2010年以来最大,部分点燃了投资者对通胀接近触顶的期待。 标普全球统计的欧元区7月制造业PMI终值自2020年6月以来首次降至萎缩区间...
Cancer metabolismIncreased glucose uptake and aerobic glycolysis are striking features of many cancers. These features have led to many techniques for screening and diagnosis, but many are expensive, less feasible or have harmful side-effects. Here, we report a sensitiveH/H NMR method to measure ...
