Exons, introns and DNA thermodynamics

Enrico Carlon, Mehdi Lejard Malki, Ralf Blossey

The genes of eukaryotes are characterized by protein coding fragments, the exons, interrupted by introns, i.e. stretches of DNA which do not carry any useful information for the protein synthesis. We have analyzed the melting behavior of randomly selected human cDNA sequences obtained from the…

Electrical damage induced by reactive ion-beam etching of lead-zirconate-titanate thin films

Caroline Soyer, Eric Cattan, Denis Remiens

Ion-beam etching of sputtered Pb(Zrx,Ti1-x)O3 (PZT) thin films with x equal to 0.54 grown on Pt/TiOx/SiO2/Si substrates has been performed using pure Ar gas and a varying CHF3/Ar gas mixing ratio. The etch rate dependence on the process parameters (gas composition, current density, and acceleration…

Left-handed propagation media via photonic crystal and metamaterials

T. Decoopman, T. Crepin, M. Perrin, S. Fasquel, A. Marteau, X. Melique, Eric Lheurette, O. Vanbesien, D. Lippens

We review the electromagnetic properties of artificial structures such as photonic band gap materials (Electromagnetic Band Gap at microwaves) and metamaterials with main emphasis on backward (left-handed) propagation media. We consider free space and guiding structures by showing how the…

Photonic devices based on preferential etching

Bob Bellini, Jean-François Larchanché, Jean-Pierre Vilcot, Didier Decoster, Romeo Beccherelli, Antonio D’alessandro

We introduce a design concept of optical waveguides characterized by a practical and reproducible process based on preferential etching of crystalline silicon substrates. Low-loss waveguides, spot-size converters, and power dividers have been obtained with polymers. We have also aligned liquid…

Design of microstrip to waveguide transition in the W band suitable antenna or integrated circuits connections

B.D. Nguyen, Claire Migliaccio, Christian Pichot, N. Rolland

This paper presents a millimeter waveguide-to-microstrip line transition based on E-mode coupling. It uses a standard W-band waveguide and a microstrip line made on alumina substrate. It has been designed for the center frequency of 94 GHz. A back-to-back transition has been done and measured…

A catalog of LEDA galaxies with DENIS measurements

G. Paturel, I. Vauglin, C. Petit, J. Borsenberger, N. Epchtein, P. Fouqué, G. Mamon

We present a catalog of near-infrared properties of LEDA galaxies, using the full resolution images from the DENIS survey. The fluxes are integrated in eight homothetic ellipses defined by their proper axis ratio, position angle and major axis (up to twice the blue diameter at the isophote 25 mag…
