The mean hydration of carbohydrates as studied by normalized 2-D radial pair distributions, Claus A. Andersson and Sø ren B. Engelsen, Journal of Molecular Graphics and Modeling.The routine takes as input the location of the centerpoint of the two spheres and the two said spheres radii and calculates the rotational common volume used for normalizing the density maps of the atoms under investigation.

we address the design of economical recursive generalized comb filters (GCFs) by proposing an ef- ficient technique to quantize the multipliers in the z-transfer function employing power-of-2 (PO2) terms. GCFs are efficient anti-aliasing decimation filters with improved selectivity and quantization noise rejection performance around the so-called folding bands with respect to classical comb filters. The proposed quantization technique guarantees perfect pole–zero cancelation in the rational z-transfer function of the GCFs, thus totally avoiding instability problems. Moreover, we propose the use of a simple droop compensator for the sake of recovering the passband droop distorting the useful digital signal in the baseband. A design example is proposed with the aim of showing the application of the proposed technique, and a practical architecture of a sample third-order GCF is discussed.
