秘鲁今天的现实同样提醒我们，制度信任不是通过口号能够建立的，它需要稳定、清晰的权力边界和长期一致的规则。秘鲁的困境正在于此，它不是没有产权，而在没有稳定保护产权的制度。1990年代向前一步，2016年后却步步后退。市场还在，但法治不稳；产权有形，但安全无感。企业家既看不清明天的政府，也看不清明年的政府，更无法判断政策与资产是否安全。在这样的环境下，再完美的产权制度，也可能沦为一纸空文。

"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.
