"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.,更多细节参见旺商聊官方下载

The threat was issued on Tuesday at a Pentagon meeting that Hegseth had demanded with Anthropic boss Dario Amodei, a source familiar with discussions told the BBC.
