"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.

Hebrew Paseq (U+05C0), which maps to lowercase l, scores 0.923 mean SSIM. This is Hebrew punctuation, not a letter, yet it renders as a vertical bar nearly identical to l. Think “paypa׀.com” with Paseq replacing the L. It scores 0.997 in Tahoma, 0.988 in Arial Unicode MS, 0.951 in Microsoft Sans Serif. The scoring surfaces it correctly.
