"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.

There is no syscall surface to attack because the code never makes syscalls. Memory safety is enforced by the runtime. The linear memory is bounds-checked, the call stack is inaccessible, and control flow is type-checked. Modern runtimes add guard pages and memory zeroing between instances.，更多细节参见雷电模拟器官方版本下载
