"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.
有时，订餐的情况会没那么顺利，Gemini 也会尝试自己先去解决突发状况，并给用户提供解决方案。有一次，披萨店在繁忙时段限制了大号披萨的下单量，Gemini 就会询问能不能点两个中号代替。
