Freudenthal Dual Lagrangians [PDF]

open access: yes, 2012
The global U-dualities of extended supergravity have played a central role in differentiating the distinct classes of extremal black hole solutions. When the U-duality group satisfies certain algebraic conditions, as is the case for a broad class of ...

Discovery of a strong magnetic field on the O star HD 191612: new clues to the future of theta1 Orionis C?

open access: yes, 2005
From observations made with the ESPaDOnS spectropolarimeter, recently installed on the 3.6-m Canada--France--Hawaii Telescope, we report the discovery of a strong magnetic field in the Of?p spectrum variable HD 191612 -- only the second known magnetic O ...

Analysis of surface waves generated on subwavelength-structured silver films [PDF]

open access: yes, 2006
Using transmission electron microscopy (TEM) to analyse the physical-chemical surface properties of subwavlength structured silver films and finite-difference time-domain (FDTD) numerical simulations of the optical response of these structures to plane ...

Line-profile tomography of exoplanet transits I: The Doppler shadow of HD 189733b

open access: yes, 2009
We present a direct method for isolating the component of the starlight blocked by a planet as it transits its host star, and apply it to spectra of the bright transiting planet HD 189733b.

Topological acceleration in relativistic cosmology

open access: yes, 2012
Heuristic approaches in cosmology bypass more difficult calculations that would more strictly agree with the standard Einstein equation. These give us the well-known Friedmann-Lemaitre-Robertson-Walker (FLRW) models, and, more recently, the feedback ...

Molecular line opacity of LiCl in the mid-infrared spectra of brown dwarfs

open access: yes, 2004
We present a complete line list for the X 1Sigma+ electronic ground state of LiCl computed using fully quantum-mechanical techniques. This list includes transition energies and oscillator strengths in the spectral region 0.3-39,640.7 cm-1 for all allowed

Correlated tunneling into a superconductor in a multiprobe hybrid structure

open access: yes, 2001
We consider tunneling in a hybrid system consisting of a superconductor with two or more probe electrodes which can be either normal metals or polarized ferromagnets. In particular we study transport at subgap voltages and temperatures.

Managing the Risk of IT Outsourcing [PDF]

open access: yes
While it can bring several benefits, IT outsourcing entails some risks. As it is the case in other types of investments or business ventures, the risk associated to an IT outsourcing project must be evaluated and managed.

Discovery of a magnetic field in the B pulsating system HD 1976

open access: yes, 2014
The presence of a magnetic field can have a strong impact on the evolution of a binary star. However, only a dozen of magnetic OB binaries are known as of today and available to study this effect, including very few magnetic pulsating spectroscopic OB ...

Figures de la signature scientifique

open access: yes, 2000
Studies of scientific collaboration based on publication have been developing for forty years. However, most of these studies are generally concentrated on productivity and the growth of ‘big science'. Involved with a sample of articles from three different fields, this work tries to reveal the patterns of publication at two levels : interdisciplinary,
