"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.
Web streams was an ambitious project that brought streaming to the web platform when nothing else existed. The people who designed it made reasonable choices given the constraints of 2014 – before async iteration, before years of production experience revealed the edge cases.

And while Clavicular has been hobnobbing with the highest-followed right-wing influencers, he has made it known that looks indeed matter to him more than anything. In an interview with conservative commentator Michael Knowles, Clavicular called Vice President JD Vance "subhuman." When asked to explain, Clavicular said Vance has a "short face width to height ratio," has a "recessed side profile," and is overweight. Gavin Newsom, the Democratic governor of California, is a chad, according to Clavicular.
