The incident also comes almost 30 years to the day since Cuban defence forces shot down two small civilian planes belonging to Brothers to the Rescue, a US-based group that searched for rafts carrying migrants from Cuba to the US.
"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.。业内人士推荐safew官方下载作为进阶阅读
