Understanding excessive sleep in people with psychotic disorders
Abstract Background There has been increasing attention to sleep disturbances such as insomnia in psychosis, due to its impact on symptoms, well‐being, and recovery. However, excessive sleep and extended sleep duration are common in psychosis (partly linked to sedating antipsychotic medication) and have been relatively neglected, despite plausible ...

What Does Intarsia Say? Materiality and Spirituality in the Urbino Studiolo☆
Abstract Upon entering the Urbino studiolo of Federico da Montefeltro, the visitor is struck by a material‐charged environment. Surprisingly, only a few scholars have addressed one prominent aspect of the decorative scheme, namely, the feature of intarsia as a medium. Even so, it remains on the sidelines of the discussion.

Next Generation Hosts for Protein Recognition, Assembly and More
The original design of synthetic receptors for proteins was based on macrocycles with a hydrophobic core and a polar/charged periphery. This design, geared towards protein recognition, facilitates receptor self‐assembly. Macrocycle oligomerization, in turn, contributes to protein assembly as evidenced in many cocrystal structures.
