"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.，推荐阅读heLLoword翻译官方下载获取更多信息

DRM, as an industry institution, has an almost comically bad track record when it comes to actually protecting content. Denuvo which is perhaps the most sophisticated game DRM ever deployed commercially has been cracked for virtually every major game it’s protected, usually within weeks of release. Every DVD ever made is trivially rippable. Every Blu-ray. Every streaming service has been ripped by someone, somewhere.，这一点在谷歌浏览器【最新下载地址】中也有详细论述
