Quadratic estimators of the frequency-wavenumber spectrum

[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991
A general representation is presented for quadratic estimators of the far-field frequency-wavenumber spectrum. The quadratic estimators are constructed from linear transformations of the array data. These linear transformations contain the windows normally associated with multiple window spectral estimators and act as multidimensional baseband ...

Frequency and spectrum of hemochromatosis mutations in Tunisia

The Hematology Journal, 2003
The occurrence of the C282Y and H63D mutations of the HFE gene, responsible for toxic iron overload in the liver (hereditary hemochromatosis), was still unknown in Tunisia. We report the screening of 194 chromosomes from 97 randomly collected cord blood samples. The mutations were analyzed by PCR followed by DNA sequencing. The mild H63D and the severe

Low-frequency Spectrum of the Crab Nebula

Nature, 1970
THE compact low-frequency radio source1 in the Crab nebula is exceptional in most of its properties. Its spectral index2 of ∼ 1.75 between 26.5 and 1,407 MHz is the highest known for a galactic continuum source, and its brightness temperature of ∼ 1014 K at 38 MHz implies an unusual emission mechanism with a high volume emissivity.
