Dark Energy and Projective Symmetry
Nurowski [arXiv:1003.1503] has recently suggested a link between the
observation of Dark Energy in cosmology and the projective equivalence of
certain Friedman-Lemaitre-Robertson-Walker (FLRW) metrics. Specifically, he
points out that two FLRW metrics with the same unparameterized geodesics have
their energy densities differing by a constant. From this he queries whether
the existence of dark energy is meaningful. We point out that physical
observables in cosmology are not projectively invariant and we relate the
projective symmetry uncovered by Nurowski to some previous work on projective
equivalence in cosmology
Les bibliothèques et la deuxième naissance Loin de porter du cinéma
Loin de porter concurrence aux exploitants de cinéma en salle, l’offre développée par les médiathèques a souvent pallié les déficiences du réseau commercial. La preuve en Nord – Pas-de-Calais où, dans l’urgence, des formations ont même émergé de façon informelle
Crystallization in a model glass: influence of the boundary conditions
Using molecular dynamics calculations and the Voronoi tessellation, we study
the evolution of the local structure of a soft-sphere glass versus temperature
starting from the liquid phase at different quenching rates. This study is done
for different sizes and for two different boundary conditions namely the usual
cubic periodic boundary conditions and the isotropic hyperspherical boundary
conditions for which the particles evolve on the surface of a hypersphere in
four dimensions. Our results show that for small system sizes, crystallization
can indeed be induced by the cubic boundary conditions. On the other hand we
show that finite size effects are more pronounced on the hypersphere and that
crystallization is artificially inhibited even for large system sizes.Comment: 11 pages, 2 figure
Practical recommendations for radium-223 treatment of metastatic castration-resistant prostate cancer
is the first targeted alpha therapy for patients with castration resistant prostate cancer and symptomatic bone metastases.
Radium-223 provides a new treatment option for this setting, but also necessitates a new treatment management approach.
We provide straightforward and practical recommendations for European nuclear medicine centres to optimize radium-223 service provision.
Methods An independent research consultancy agency observed radium-223 procedures and conducted interviews with all key staff members involved in radium-223 treatment delivery in 11 nuclear medicine centres across six countries (Germany, Italy, the Netherlands, Spain, Switzerland and the UK) experienced in administering radium-223. The findings
were collated and discussed at a meeting of experts from these centres, during which key consensus recommendations were defined. Results The recommendations cover centre organization and preparation; patient referral; radium-223 ordering, preparation and disposal; radium-223 treatment delivery/administration; and patient experience. Guidance includes structured coordination and communication within centres and multidisciplinary teams, focusing on sharing best practice to provide high quality, patient-centred care throughout the treatment
pathway.
Conclusions These expert recommendations are intended to complement existing management guidelines. Sharing best practice and experience will help nuclear medicine centres to optimize radium-223 service provision and improve patient care

Comment distribuer des livres comme des petits pains à ce public qui se refuse à fréquenter la médiathèque ? En s’adressant au boulanger, bien sûr ! C’était simple et, comme pour l’oeuf de Colomb, il suffisait d’y penser. Médecins, fleuristes, cafetiers de Lomme se sont pris au jeu de ce bookcrossing qui redessine les limites de l’interprofession
Coopération transfrontalière
Dans une région frontalière, la coopération internationale semble à la fois logique et séduisante. Les volontés existent, les structures et les programmes d’aide
aussi, mais cela ne suffit pas toujours. Visites aux points de contact
