"At the River Itchen we have more than £70m worth of improvements to improve water quality as part of a wider plan for the River Test and Itchen, we will be announcing these in more detail later this year."
"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
在头部行业中，半导体业下滑较为明显——在披露研发人员的企业数量增长47.58%的情况下，研发人员增速仅为7.71%，导致平均值的跌幅达到27.02%。叠加研发投入五年增长53.87%，说明该行业的资金优先投向了技术与设备，而非人力扩张。
