Humor can improve a performance of creative problem solving; this phenomenon was repeatedly demonstrated in various studies. However, mechanisms underlying this phenomenon are still unclear. We analyze the possible mechanisms of how humor facilitates creative problem solving. The experiment demonstrates that preliminary humor production facilitates insight problem solving. There is no such an e...

Simultaneous vibration welding of 304 stainless steel was carried out with an eccentric circulating vibrator and a magnetic telescopic vibrator at subresonant (362 Hz and 59.3 Hz) and resonant (376 Hz and 60.9 Hz) frequencies. The experimental results indicate that the temperature gradient can be increased, accelerating nucleation and causing grain refinement during this process. During simulta...
