This paper studies the coordinated motion of a group of agents evolving on a Lie group. Left- or right-invariance with respect to the absolute position on the group lead to two different characterizations of relative positions and two associated definitions of coordination (fixed relative positions). Conditions for each type of coordination are derived in the associated Lie algebra. This allows to formulate the coordination problem on Lie groups as consensus in a vector space. Total coordination occurs when both types of coordination hold simultaneously. The discussion in this paper provides a common geometric framework for previously published coordination control laws on SO(3), SE(2) and SE(3). The theory is illustrated on the group of planar rigid motion SE(2). [less ▲]

Infantile pyknocytosis (IP) is a rare hematological entity of newborns. It is a form of hemolytic anemia with unusual red cell morphology: the red blood cells are distorted, irregular, and small with many projections. Spontaneous resolution usually occurs by 4-6months of age. OBSERVATION: We describe the clinical features and biological parameters of 5 cases of IP. The first symptoms were always early jaundice, which required phototherapy. Anemia was severe in all babies and red blood cell transfusion was needed. CONCLUSION: IP is a rare cause of neonatal anemia whose diagnosis is based on a careful peripheral blood smear examination. In our study, anemia was severe and required red blood cell transfusion. Ethnic specificity and familial occurrence are reported in our experience. [less ▲]

We review the properties of the very young (˜ 2 Myr) open cluster NGC 6383. The cluster is dominated by the massive binary HD 159176 (O7 V + O7 V). The distance to NGC 6383 is consistently found to be 1.3 ± 0.1 kpc and the average reddening is determined to be E(bv) = 0.32 ± 0.02. Several pre-main sequence candidates have been identified using different criteria relying on the detection of emission lines, infrared excesses, photometric variability and X-ray emission. [less ▲]

We address the problem of finding indirect overlay paths that reduce the latency between pairs of nodes in an overlay. To this end we propose to rely on an Internet Coordinate System (ICS), namely Vivaldi, to estimate RTTs and help find these interesting detours. We define two initial criteria to illustrate our approach and assess their true/false positive rates. [less ▲]

Nous voudrions communiquer des repères cliniques clairs des troubles de l’attention avec ou sans hyperactivité. L’objectif est de mieux reconnaître ce trouble, avec plus d’objectivité. De même, nous évoquons d'autres difficultés qui peuvent être simultanément présentes mais qui nécessitent d'en être distinguées. Nous espérons ainsi donner aux cliniciens des repères plus précis et nuancés. [less ▲]

We present a mid-term report on a project aimed at partially identifying the main modes of pulsation in the rapidly pulsating subdwarf B star PG 1047+003. Using the unique HIT-MS mode on FORS2 at the VLT we obtained ˜3000 spectra spread over 4 consecutive half-nights with a typical sampling rate of 20 s. These will be used to extract monochromatic pulsation amplitudes and phases that can be fit to model predictions in order to determine the degree ℓ of the mode in question. [less ▲]
