The Core of FSE - CMA Behavior Theory 1 The Core of FSE - CMA Behavior Theory 1

This chapter presents the basics of the current theory regarding the behavior of blind fractionally-spaced and/or spatial-diversity equalizers (FSE) adapted via the constant modulus algorithm (CMA). The constant modulus algorithm, which was developed in the late 1970s and disclosed in the early 1980s, performs a stochastic gradient descent of a cost function that penalizes the dispersion of the...

Presence of AmpC beta-lactamases, CSA-1, CSA-2, CMA-1, and CMA-2 conferring an unusual resistance phenotype in Cronobacter sakazakii and Cronobacter malonaticus.

Here we describe the presence of two very similar but unusual variants of AmpC cephalosporinase in each Cronobacter sakazakii and C. malonaticus isolates conferring resistance exclusively to first generation cephalosporins. During a survey on the antibiotic resistance patterns of C. sakazakii and C. malonaticus strains isolated from a milk powder production facility, originally two different ph...

Moreover, model selection and evaluation of prediction rules proves to be highly difficult in this situation for several reasons. Firstly, the hazard of overfitting, which is common to all prediction problems, is increased by high dimensionality. Secondly, the usual evaluation scheme based on the splitting into learning and test data sets often applies only partially in the case of small sample...

CMA Workshop on Spectral Theory

The physicist R. Feynman advanced an idea of forming an abstract operator calculus for a finite number of noncommuting operators by attaching time indices to the operators. In joint work with G.W. Johnson, time-ordering measures are introduced to serve as weights for various functional calculi, such as the Weyl functional calculus (equal weights), the Kohn-Nirenberg or ordered functional calcul...
