Q uantum interference effects lie at the heart of technologies that promise radically new capabilities for sensors, secure communications, and computing. Most existing experiments and applications rely on one photon interfering with itself, or two photons interfering with each other. However, the interference of a larger number of particles leads to a richer variety of phenomena, and may enable...

Based on the Randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. The index obtained by multiplying three factors; (nb2 + nr), nc and M; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

Histone acetyltransferases (HATs) play a key role in transcription control, cell proliferation and differentiation by modulating chromatin structure; however, little is known about their own regulation. Here we show that expression of the viral oncoprotein SV40 T antigen increases histone acetylation and global cellular HAT activities. In addition, it enhances CREB-binding protein HAT activity ...

The arguments presented by González-Nuevo et al. (2006) in favour of theMexican Hat Wavelet Family (MHWF) are critically discussed here. These authors allege the optimal properties of this new class of filters in the detection of point sources embedded in a noise background but their claim is not based upon a solid mathematical foundation and proof.
