The RADAR protocol and its underlying neighbourhood discovery framework extend the ANTS toolkit by giving active nodes the ability to discover dynamically other active nodes close to them without relying on any configuration file. Such an automatic discovery is the key to administration of large or sparse active networks and the first step towards an efficient active routing. Active nodes will use their local IP routing table to run an extended ring search in their domain. An Additive Increase Multiplicative Decrease control allows RADAR to discover several neighbours per physical interface without searching too far away or fixing a maximum distance a priori. The protocol is complemented by a traffic-driven discovery that can grab capsules coming from unknown nodes (mainly outside the local domain) and trigger targetted probing of those addresses.

We prove the existence and uniqueness of a projectively equivariant symbol map (in the sense of Lecomte and Ovsienko) for the spaces D_p of differential operators transforming p-forms into functions, over R^n. As an application, we classify the Vect(M)-equivariant maps from D_p to D_q over a smooth manifold M, recovering and improving earlier results of N. Poncin. This provides the complete answer to a question raised by P. Lecomte about the extension of a certain intrinsic homotopy operator. [less ▲]

The cellular prion protein (PrPc) is a glycolipid-anchored cell surface protein that usually exhibits three glycosylation states. Its post-translationally modified isoform, PrPsc, is involved in the pathogenesis of various transmissible spongiform encephalopathies (TSEs). In bovine species, BSE infectivity appears to be restricted to the central nervous system; few or no detectable infectivity is found in lymphoid tissues in contrast to scrapie or variant CJD. Since expression of PrPc is a prerequisite for prion replication, we have investigated PrPc expression by bovine immune cells. Lymphocytes from blood and five different lymph organs were isolated from the same animal to assess intra- and interindividual variability of PrPc expression, considering six individuals. As shown by flow cytometry, this expression is absent or weak on granulocytes but is measurable on monocytes, B and T cells from blood and lymph organs. The activation of the bovine cells produces an upregulation of PrPc. The results of our in vitro study of PrPc biosynthesis are consistent with previous studies in other species. Interestingly, western blotting experiments showed only one form of the protein, the diglycosylated band. We propose that the glycosylation state could explain the lack of infectivity of the bovine immune cells. [less ▲]

As part of their plans to diversify and globalize their foreign relations, the EU and MERCOSUR have been working to establish closer links. They have a project to create an interregional Association based on political dialogue, cooperation and trade issues. To understand the evolution of this interregional relationship, it is also important to take into account the USAs’ project, which seeks to create a hemispheric market for 2005 and in which MERCOSUR is participating. There is competition between Europe and the USA in the Southern Cone. While the EU has often provided support for institution building in MERCOSUR, the latter has frequently been destabilized by US regionalist strategy. The USA has often taken advantage of its special relationship with Argentina. However, the open crises that Argentina has faced since December 2001, and the US attitude towards the crises, appear to have affected the Buenos Aires foreign policy alignment with Washington. What geopolitical consequences could this have for the area? And what is the US position on this development? Has the EU taken advantage of the situation to reinforce its interregional partnership with MERCOSUR and to counteract US influence in the region? [less ▲]

We report the case of a 54 year old man presenting atypical chest pain. The echocardiogram showed a dilatation of the coronary sinus. Subsequently the angiographic evaluation with cardiac catheterization demonstrated a coronary artery fistula between the circumflex artery and the coronary sinus and between a megaanevrysmal right coronary artery and the coronary sinus. No significant left to right shunt was discovered, however. [less ▲]

The bacterial acyltransferases of the SxxK superfamily vary enormously in sequence and function, with conservation of particular amino acid groups and all-alpha and alpha/beta folds. They occur as independent entities (free-standing polypeptides) and as modules linked to other polypeptides (protein fusions). They can be classified into three groups. The group I SxxK D,D-acyltransferases are ubiquitous in the bacterial world. They invariably bear the motifs SxxK, SxN(D), and KT(S)G. Anchored in the plasma membrane with the bulk of the polypeptide chain exposed on the outer face of it, they are implicated in the synthesis of wall peptidoglycans of the most frequently encountered (4-->3) type. They are inactivated by penicillin and other beta-lactam antibiotics acting as suicide carbonyl donors in the form of penicillin-binding proteins (PBPs). They are components of a morphogenetic apparatus which, as a whole, controls multiple parameters such as shape and size and allows the bacterial cells to enlarge and duplicate their particular pattern. Class A PBP fusions comprise a glycosyltransferase module fused to an SxxK acyltransferase of class A. Class B PBP fusions comprise a linker, i.e., protein recognition, module fused to an SxxK acyltransferase of class B. They ensure the remodeling of the (4-->3) peptidoglycans in a cell cycle-dependent manner. The free-standing PBPs hydrolyze D,D peptide bonds. The group II SxxK acyltransferases frequently have a partially modified bar code, but the SxxK motif is invariant. They react with penicillin in various ways and illustrate the great plasticity of the catalytic centers. The secreted free-standing PBPs, the serine beta-lactamases, and the penicillin sensors of several penicillin sensory transducers help the D,D-acyltransferases of group I escape penicillin action. The group III SxxK acyltransferases are indistinguishable from the PBP fusion proteins of group I in motifs and membrane topology, but they resist penicillin. They are referred to as Pen(r) protein fusions. Plausible hypotheses are put forward on the roles that the Pen(r) protein fusions, acting as L,D-acyltransferases, may play in the (3-->3) peptidoglycan-synthesizing molecular machines. Shifting the wall peptidoglycan from the (4-->3) type to the (3-->3) type could help Mycobacterium tuberculosis and Mycobacterium leprae survive by making them penicillin resistant. [less ▲]
