Generalising the definition to commuting $d$-tuples of operators, a number authors have considered structural properties $m$-isometric, $n$-symmetric and $(m,n)$-isosymmetric in recent past. This note is an attempt take mystique out this extension show how large these follow from more familiar arguments used prove single operator version properties.

Zasp52 is a member of the PDZ-LIM domain protein family in Drosophila, which comprises Enigma, ENH, ZASP, Alp, CLP36, RIL, and Mystique in vertebrates. Drosophila Zasp52 colocalizes with integrins at myotendinous junctions and with α-actinin at Z-disks, and is required for muscle attachment as well as Z-disk assembly and maintenance. Here we document 13 Zasp52 splice variants giving rise to six...

Introduction: The Idea and the Method Elsewhere, we have discussed perceptually-seductive technology interactive media designed to engage relatively direct perception rather than thoughtful reflection (Waterworth, 2001). Our Focus, Locus and Sensus (FLS) model of experience suggests that digital media that have this effect also generate a strong sense of presence (Waterworth and Waterworth, 200...
