Context. The spectral energy distribution (SED) in the millimetre to centimetre range is an extremely useful tool for characterising dust protostellar envelopes as well free-free emission from protostar and outflow. Actually, evolutionary status of solar-type protostars often based on their SED near-infrared range. In addition, presence or absence can be considered indicator source stage (Class...

We perceive objects in the world as stable despite their constantly changing image properties due to factors like occlusion, visual noise, and eye movements. Recent results demonstrate that perception of low-level stimulus features and even more complex perception of human identity are biased towards recent percepts (Fisher & Whitney, 2014; Liberman, Fisher & Whitney, 2014). This effect is ofte...
