Affine Kac-Moody algebras, CHL strings and the classification of tops
Candelas and Font introduced the notion of a `top' as half of a three dimensional reflexive polytope and noticed that

A first look at galaxies with the DENIS survey
We review the various steps for the extraction of extended sources, principally galaxies, from the DENIS images. The capabilities of

Aging, rejuvenation and memory effects in re-entrant ferromagnets
We have studied the slow dynamics of the ferromagnetic phases of the re-entrant CdCr_{2x}In_{2-2x}S_4 system for 0.85<x<=1 by means of

A HST Spectroscopic study of QSOs with intermediate redshift damped Lyman-alpha systems
We present HST spectra for a sample of six QSOs with intermediate redshift (z_a < 1) damped Ly-alpha systems. These

Comparative review of aging properties in spin glasses and other disordered materials
Aging phenomena have been studied in very different materials like polymers, supercooled liquids or disordered orientational crystals. We recall here
