Museums sometimes ask multimedia producers for the ultimate exhibit: it actively involves groups of people in educational interactions, it enhances the visitors' understanding of the museum as a whole, it gives each visitor the impression that the exhibit is learning about and responding specifically to him or her, it requires no staff to run, and it is unlike anything ever seen before on this ...

the box of seed was four times the cost of conventional seed. When several rainless days had passed after planting, she went into the field with a hired worker to hand-water each seed to ensure germination-an extraordinary level of attention to a cotton field. Such fields were later used to calculate the " yield advantage " of Bt seed.

There is, however, an alternative view on relations, the antipositionalist view, according to which the constituents of the complexes of a relati...

in terms of the crystal bases theory [K] and its application to the periodic box-ball systems following [S2] and [KS3]. The bijection φ was originally introduced in order to show the so-called X = M formula (see [O, S4] for reviews) by using its statistic preserving property. Recently, another application of the bijection φ to the box-ball systems [TS, T] was found [KOSTY]. In this context, the...

We present a comprehensive theory of boundedness properties for Polish groups developed with a main focus on Roelcke precompactness (precompactness of the lower uniformity) and Property (OB) (boundedness of all isometric actions on separable metric spaces). In particular, these properties are characterised by the orbit structure of isometric or continuous affine representations on separable Ban...
