Intense predation pressure from echolocating bats has led to the evolution of a host anti-bat defences in nocturnal moths. The wings moths are covered scales that exhibit intricate shapes and sculpted nano structures. Here, we reveal this scale layer forms metamaterial ultrasound absorber is 111 times thinner than longest absorbed wavelength. Both experimental numerical analyses individual vibr...

• We propose a new fuzzy Weighted Influence Non-linear Gauge System (WINGS). uncover interdependencies by the direction, intensity and strength of dependencies. Fuzzy judgments are used to cope with uncertainties in untested technologies. introduce ideal nadir alternatives WINGS study solution space. present case evaluate ten advanced technology projects at NASA. Evaluating NASA is difficult du...
