"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.
«Я, к сожалению, ничего не знаю об этом происшествии — не видел сообщений и не располагаю информацией о деталях. Но если то, как вы передаете формулировку, верно, в том плане, что поскольку рядом российское судно, то, значит, дрон российский — это достаточно абсурдное заявление», — сказал представитель Кремля.
