Equal Protection- The Social Dimension of European Community Law
There are two reasons for drawing attention to the social dimension of European Community law. First, the EEC treaty comprises different provisions on social policy whose importance is consistently underestimated: the treaty is often considered as merely establishing a common market and as only concerning economic problems. This approach is prominent in the United States, where the business world is primarily interested in trade with, and within, the common market, and where much literature is devoted to this subject. Second, the social provisions of the EEC treaty have given rise to an interesting evolution in the case law of the Court of Justice of the European Communities, on equal protection in particular. As a result, the Court\u27s case law has gradually begun to show some interesting parallels with previous developments in American law

Inference of the Cold Dark Matter substructure mass function at z=0.2 using strong gravitational lenses
We present the results of a search for galaxy substructures in a sample of 11
gravitational lens galaxies from the Sloan Lens ACS Survey. We find no
significant detection of mass clumps, except for a luminous satellite in the
system SDSS J0956+5110. We use these non-detections, in combination with a
previous detection in the system SDSS J0946+1006, to derive constraints on the
substructure mass function in massive early-type host galaxies with an average
redshift z ~ 0.2 and an average velocity dispersion of 270 km/s. We perform a
Bayesian inference on the substructure mass function, within a median region of
about 32 kpc squared around the Einstein radius (~4.2 kpc). We infer a mean
projected substructure mass fraction at the 68
percent confidence level and a substructure mass function slope < 2.93
at the 95 percent confidence level for a uniform prior probability density on
alpha. For a Gaussian prior based on Cold Dark Matter (CDM) simulations, we
infer and a slope of =
1.90 at the 68 percent confidence level. Since only one
substructure was detected in the full sample, we have little information on the
mass function slope, which is therefore poorly constrained (i.e. the Bayes
factor shows no positive preference for any of the two models).The inferred
fraction is consistent with the expectations from CDM simulations and with
inference from flux ratio anomalies at the 68 percent confidence level.Comment: Accepted for publication on MNRAS, some typos corrected and some

The Quest for the Heaviest Uranium Isotope
We study Uranium isotopes and surrounding elements at very large neutron
number excess. Relativistic mean field and Skyrme-type approaches with
different parametrizations are used in the study. Most models show clear
indications for isotopes that are stable with respect to neutron emission far
beyond N=184 up to the range of around N=258.Comment: 4 pages, 5. figure
The Lenses Structure & Dynamics Survey: The internal structure and evolution of E/S0 galaxies and the determination of H_0 from time-delay systems
The Lenses Structure & Dynamics (LSD) Survey aims at studying the internal
structure of luminous and dark matter - as well as their evolution - of field
early-type (E/SO) galaxies to z~1. In particular, E/S0 lens galaxies are
studied by combining gravitational lensing, photometric and kinematic data
obtained with ground-based (VLA/Keck/VLT) and space-based telescopes (HST).
Here, we report on preliminary results from the LSD Survey, in particular on
(i) the constraints set on the luminous and dark-matter distributions in the
inner several R_eff of E/S0 galaxies, (ii) the evolution of their stellar
component and (iii) the constraints set on the value of H_0 from time-delay
systems by combining lensing and kinematic data to break degeneracies in
gravitational-lens models.Comment: 4 pages; Proceeding for the "Multi-Wavelength Cosmology" conference,
