This brief note views to the Welch bound inequality using the idea of the kernel trick from the machine learning research area. From this angle, some novel insights of the inequality are obtained.

This correspondence presents the results of the enumeration of Costas arrays of order 27: all arrays found, except for one, are accounted for by the Golomb and Welch construction methods.

The scattered fields of a number of targets in free space are measured. Their complex natural resonances are extracted from the late time responses, using the generalized pencil-of-function method. The complex natural resonances, as the targets are immersed in a lossy medium, are investigated using Baum’s transform. The results of the complex natural resonances for various targets are expected ...

We review several applications of Lempel–Ziv complexity to the characterization of neural responses. In particular, Lempel–Ziv complexity allows to estimate the entropy of binned spike trains in an alternative way to the usual method based on the relative frequencies of words, with the de7nitive advantage of no requiring very long registers. We also use complexity to discriminate neural respons...

ABSTRACT: In this paper, the complete convergence and the complete moment convergence of weighted sums for an array of negatively superadditive dependent random variables are established. The results generalize the Baum-Katz theorem on negatively superadditive dependent random variables. In particular, the Marcinkiewicz-Zygmund type strong law of large numbers of weights sums for sequences of n...

L. Frank Baum’s The Wonderful Wizard of Oz has become popular as a teaching tool in economics. It has been argued that it was written as an allegory of Populist demands for a bimetallic monetary system in the late 19th century. The author argues that Baum was not sympathetic to Populist views and did not write the story as a monetary allegory.
