Imec presents a new ‘hourglass’ model for modeling low-current filamentary switching in amorphous HfO2 RRAM. The model describes the set and reset processes as a dynamic oxygen vacancy flow between ...
The mid-embryonic stages are strikingly similar in animals, plants and algae, revealing the shared crucial stages in the evolution of complex life forms. Recent observations in brown algae from ...
It was first observed two centuries ago that many animal embryos converge on a similar form during development, only to diverge afterwards. This temporal 'waist' in the so-called hourglass model of ...
