Yet building nanoscale transistors presents a basic problem. They are bound by physical constraints that limit how ...

We’ve seen our share of light-up jewelry over the years, but for some reason — probably power — it’s almost always earrings or necklaces. So when we saw [ROBO HUB]’s LED ring, we had to ...

% The gate has two inputs and one final output. function T=xor_gate(A,B) % First we have to find Not(A) Take the output as "S". S=not_gate(A); % Then we have to find Not(B) Take the output as "K".
