Some characterizations of specially multiplicative functions
(2003)
- article
A multiplicative function f is said to be specially multiplicative if there is a completely multiplicative function fA such that f(m)f(n)=∑d|(m,n)f(mn/d2)fA(d) for all m and n. For example, the divisor functions and ...

Removing impulse bursts from images by training-based filtering
(2003)
- article
The characteristics of impulse bursts in remote sensing images are analyzed and a model for this noise is proposed. The model also takes into consideration other noise types, for example, the multiplicative noise present ...

TGF-beta induces the expression of SAP30L, a novel nuclear protein
(2003)
- article
BackgroundWe have previously set up an in vitro mesenchymal-epithelial cell co-culture model which mimics the intestinal crypt villus axis biology in terms of epithelial cell differentiation. In this model the fibroblast-induced ...
Fine structure of the low-frequency spectra of heart rate and blood pressure
(2003)
- article
Background
The aim of this study was to explore the principal frequency components of the heart rate and blood pressure variability in the low frequency (LF) and very low frequency (VLF) band. The spectral composition of ...
Fabrication of DNA monolayers on gold substrates and guiding of DNA with electric field
(2003-12)
- article
We report electrically controlled selective coating of gold electrodes with mixed monolayers of oligonucleotides and alkanethiol passivation molecules. Gold nanoparticles are used as labels for visualization and voltage ...
