Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation ...

Abstract: This study proposes a cleaning machine using a multistage planetary gear mechanism to remove accumulated grease from kitchen ducts with various geometries, including circular and square ...

Abstract: In rotary vector (RV) reducers, both the planet gears and cycloidal gears are mounted on the crankshafts and rotated at the same speed. As a result, the rotational order/frequency of the ...

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on the gas giant—so thick that no spacecraft has been able to measure exactly ...

According to @ai_darpa, a new AI-powered simulation demonstrates a gear system with extreme ratios, where the final gear rotates slower than the age of the cosmos. This showcases the power of advanced ...
