"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.
We now update badges in the Dock and Applications menu even if you run updates from another app store or via Terminal. We fixed an issue where pressing “Cancel” buttons might not give immediate feedback. And we now send notifications when an app is uninstalled and AppCenter is closed, such as when uninstalling from the applications menu or dock.
