Donald M. Baer Remembered.

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...

Vernon Remembered

Editor's Note: The world of neuroscience lost one of its pioneers when Vernon B. Mountcastle, M.D., died January 11 in Baltimore at age 96. Often referred to as " the father of neuroscience, " Mountcastle defied early skeptics by showing how cylinders of neurons, dedicated to specific tasks, work together. This month's Cerebrum features remembrances from two colleagues influenced by Mountcastle...

Locally Compact Baer Rings

Locally direct sums [W, Definition 3.15] appeared naturally in classification results for topological rings (see, e.g.,[K2], [S1], [S2], [S3], [U1]). We give here a result (Theorem 3) for locally compact Baer rings by using of locally direct sums. 1. Conventions and definitions All topological rings are assumed associative and Hausdorff. The subring generated by a subset A of a ring R is denote...
