The 10th congress of the USERN organization was held on November 8-10 in Campinas, Brazil. Some time has gone by, so it is due time for me to report on the event. I could not attend in person for a cause of force majeure, but I was connected via zoom, and I also delivered two recorded speeches plus one talk in one>

A team of researchers has created an alternative to conventional logic gates, demonstrated them in silicon, and dubbed them "chaogates." They used 'chaotic' patterns to encode and manipulate inputs to produce a desired output, in that they selected desired patterns from the infinite variety offered by a chaotic system>
This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere>
Light propagation usually goes both ways; it is reciprocal in that the trajectory of light traveling one direction is identical in the opposite direction. Isolators and circulators, which make light propagate only in one direction, are vital building blocks in many modern laser and communication systems, but are almost>
