The co-occurrence of objects in visual scenes reflects the semantic structure of the world: cups are more likely to appearin scenes with tables than airplanes, for example. Both human and machine vision use these co-occurrences to supportrecognition of individual objects. A reasonable assumption is that these co-occurrences are ubiquitous and present forall perceivers. However, the scenes observed by infants are highly dependent on their body postures and locations, bothof which change dramatically over the first year of post-natal life. To measure these changing co-occurrences in infant-perspective scenes, we collected images from infants wearing head cameras in everyday home environments comparingthree age groups: 1-3, 6-8 and 11-12 months. Using graph theoretical analysis, we conclude that the semantic structure ofscenes in 6-8 months differs from whats in younger and older infants.

The search for materials with flat electronic bands continues due to their potential to drive strong correlation and symmetry breaking orders. Electronic moirés formed in van der Waals heterostructures have proved to be an ideal platform. However, there is no holistic experimental picture for how superlattices modify electronic structure. By combining spatially resolved angle-resolved photoemission spectroscopy with optical spectroscopy, we report the first direct evidence of how strongly correlated phases evolve from a weakly interacting regime in a transition metal dichalcogenide superlattice. By comparing short and long wave vector moirés, we find that the electronic structure evolves into a highly localized regime with increasingly flat bands and renormalized effective mass. The flattening is accompanied by the opening of a large gap in the spectral function and splitting of the exciton peaks. These results advance our understanding of emerging phases in moiré superlattices and point to the importance of interlayer physics.
