"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.
«В случае с Китаем или Россией авианосцы столкнутся с реальной опасностью, поэтому критика [авианесущих кораблей] обоснована», — говорится в материале.

After the work the company had done on AppleWorks 3.0, Simonsen felt ready to jump into the Macintosh market with a “Mac AppleWorks” of their own – they called it Beagle Works. Unfortunately, other companies – giants in the Mac market such as Microsoft, Claris, and Symantec – had the same idea. Their resources were far greater than Beagle Bros had imagined, and the race was costly.，推荐阅读Line官方版本下载获取更多信息
