Mackay Antisymmetry Space Groups

By using the antisymmetry characteristic method implemented in computer programs written in Mathematica 4, from 230 space symmetry groups are derived 1191 Mackay groups of the type M1, 5005 groups of the type M2, 19467 groups of the type M3, 72587 groups of the type M4, 191728 groups of the type M5, and 598752 groups of the type M6. Mackay groups are the minimal representation of Zamorzaev’s mu...

smoking, or by a combination of the three, and to pack them into barrels for transport. The cod and its relatives hake and haddock, were a different matter and more easily preserved than herring. The pursuit of cod took fishermen much further away. A huge industry developed, centred on Bergen, where ships exchanged dried fish for grain. Archaeological excavations in the Norwegian Lofoten Island...

DONALD M . MACKAy AND WARREN

The maximum rate at which a synaptic link could theoretically transmit information depends on the type of coding used. In a binary modulation system it depends chiefly on the relaxation time, and the limiting capacity equals the maximum attainable impulse rate. In a system using pulse-interval modulation, temporal precision may be a more important limiting factor. It is shown that in a number o...

The Perceptual Loop Theory Not Disconfirmed: A Reply to MacKay

Since then, the situation has hardly changed. In his paper, MacKay (1992) outlines his connectionist Node Structure theory and cites some data with which it is compatible. But that is barely progress. What one would like to see is a concerted effort to disprove the theory’s predictions in a truly Popperian fashion. However, neither MacKay nor others (including myself) have endeavored on this en...
