"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.

第一百二十六条 被处罚人不服行政拘留处罚决定，申请行政复议、提起行政诉讼的，遇有参加升学考试、子女出生或者近亲属病危、死亡等情形的，可以向公安机关提出暂缓执行行政拘留的申请。公安机关认为暂缓执行行政拘留不致发生社会危险的，由被处罚人或者其近亲属提出符合本法第一百二十七条规定条件的担保人，或者按每日行政拘留二百元的标准交纳保证金，行政拘留的处罚决定暂缓执行。
