"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.

随着AI模型规模不断扩大，数据中心的能源需求也在迅速增加。一座大型AI数据中心的功耗可能达到500MW甚至1GW，这相当于一座中型发电站的规模。与此同时，大型AI训练系统可能需要数万条高速光连接才能维持稳定运行。数据传输能力已经成为AI系统性能的重要因素。
