We analysed the structural properties of protein regions containing arrays of perfect and nearly perfect tandem repeats. Naturally occurring proteins with perfect repeats are practically absent among the proteins with known 3D structures. The great majority of such regions in the Protein Data Bank are found in the proteins designed de novo. The abundance of natural structured proteins with tand...

Recent discourse in archaeological theory has highlighted that the discipline’s approach to existence and materiality is firmly entrenched in traditions of modern thought (Thomas 1996, 2004; Tilley 2004). It has also been shown that archaeological methodology has a tendency to be used as an interpretative metaphor by other modern disciplines in the description of their own methodologies (Miller...

An app developed by a private firm and customised by a hospital trust has been helping senior nurses carry out ward inspections.

In this paper we study the family of oriented transitive 3–hypergraphs that arrive from cyclic permutations and intervals in the circle to search for the notion of perfection on hypergraphs.

In this study, we report a new visual shape illusion, the eggs illusion, in which circular disks located at the midpoints between adjacent grid intersections are perceived as being deformed to ellipses. In Experiment 1, we examined the eggs illusion by using a matching method and found that grid luminance and patch size play a critical role in producing the illusory deformation. In Experiment 2...

In the recently discovered sound-induced illusory flash phenomenon, a single flash accompanied with two auditory beeps is perceived as two flashes in a majority of trials. Here we asked what the neural substrates distinguishing illusion and no-illusion (i.e. perception of single flash) percepts are under identical stimulus configuration. Wavelet based method was used to analyze gamma band (> 30...
