De la communication, souligner non les vertus, mais les vices ; examiner, au titre de ses pathologies - et plus spécialement de ses pathologies sociales -, non les biais dont elle peut faire l'objet, mais ceux à la source desquels il arrive qu'elle se trouve ; l'envisager, non comme facteur de prévention ou de résorption de ces pathologies, mais plutôt comme leur éventuel vecteur d'aggravation circulaire, voilà comment pourrait être résumé à grands traits le propos du dossier ouvert dans la présente livraison de Questions de communication. Programme exorbitant : quelques articles réunis pour la cause ne sauraient épuiser ni même baliser avec précision une problématique pouvant aller, de façon très reçue, des phénomènes d'addiction électronique et des syndromes de déréalisation ou d'isolement induits par les technologies du virtuel aux dispositifs de propagande et autres techniques de lissage des différends politiques ou sociaux. Programme qui n'en paraîtra pas moins incongru au regard des conceptions enchantées de la communication et de la doxa qui l'institue non seulement en principe actif de la vie sociale en général, mais encore en ressource de première nécessité et en valeur indiscutable.

Our capacity to perceive and memorize information is limited to approximately seven (plus or minus two) elements. An element can be defined either as a single bit or as a coherent sequence of organized bits. This article hypothesizes that, even without explicit theorization, such a rule was working on the earliest writers who first handled accentual prosody, i.e. the 12th and 13th century European poets. In their poetry, one can note a general trend to move towards a “seven-unit disposition” of syllables, verses and strophes. Another evidence of my hypothesis is shown by the greater prevalence rate of this disposition in orally-spread poems than in written ones. [less ▲]

The inflammatory bowel diseases (IBD) Crohn's disease and ulcerative colitis are common causes of morbidity in children and young adults in the western world. Here we report the results of a genome-wide association study in early-onset IBD involving 3,426 affected individuals and 11,963 genetically matched controls recruited through international collaborations in Europe and North America, thereby extending the results from a previous study of 1,011 individuals with early-onset IBD. We have identified five new regions associated with early-onset IBD susceptibility, including 16p11 near the cytokine gene IL27 (rs8049439, P = 2.41 x 10(-9)), 22q12 (rs2412973, P = 1.55 x 10(-9)), 10q22 (rs1250550, P = 5.63 x 10(-9)), 2q37 (rs4676410, P = 3.64 x 10(-8)) and 19q13.11 (rs10500264, P = 4.26 x 10(-10)). Our scan also detected associations at 23 of 32 loci previously implicated in adult-onset Crohn's disease and at 8 of 17 loci implicated in adult-onset ulcerative colitis, highlighting the close pathogenetic relationship between early- and adult-onset IBD.

We examine the complex dynamics arising when a water droplet bounces on a horizontal soap film suspended on a vertically oscillating circular frame. A variety of simple and complex periodic bouncing states are observed, in addition to multiperiodicity and period-doubling transitions to chaos. The system is simply and accurately modeled by a single ordinary differential equation, the numerical solution of which captures all the essential features of the observed behavior. Iterative maps and bifurcation diagrams indicate that the system exhibits all the features of a classic low-dimensional chaotic oscillator. [less ▲]

We present the results of a combined experimental and theoretical investigation of droplets falling onto a horizontal soap film. Both static and vertically vibrated soap films are considered. In the static case, a variety of behaviours were observed, including bouncing, crossing and partial coalescence. A quasi-static description of the soap film shape yields a force–displacement relation that provides excellent agreement with experiment, and allows us to model the film as a nonlinear spring. This approach yields an accurate criterion for the transition between droplet bouncing and crossing. Moreover, it allows us to rationalize the observed constancy of the contact time and scaling for the coefficient of restitution in the bouncing states. On the vibrating film, a variety of bouncing behaviours were observed, including simple and complex periodic states, multi-periodicity and chaos. A simple theoretical model is developed that captures the essential physics of the bouncing process, reproducing all observed bouncing states. The model enables us to rationalize the observed coexistence of multiple periodic bouncing states by considering the dependence of the energy transferred to the droplet on the phase of impact. Quantitative agreement between model and experiment is deduced for simple periodic modes, and qualitative agreement for more complex periodic and chaotic bouncing states. Analytical solutions are deduced in the limit of weak forcing and dissipation, yielding insight into the contact time and periodicity of the bouncing states. [less ▲]

Background: Results of nonmyeloablative HCT in pts with HLA-mismatched donors have been disappointing due to high incidence of graft rejection and severe acute GVHD. Recent studies have suggested that infusion of mesenchymal stem cells (MSC) the day of HCT might promote engraftment and prevent acute GVHD after myeloablative allogeneic HCT. However, some studies suggested that MSC co-infusion might abrogate graft-versus-host alloreactivity and graft-versus-tumor effects. This prompted us to investigate whether MSC infusion a few hours before HCT could allow nonmyeloablative HCT from HLA-mismatched donors to be performed safely (i.e. with a 100-day incidence of nonrelapse mortality < 35%). Methods: 20 patients with hematological malignancies were given MSC (1-2 x 10E6 cells/kg) from third party donors a few hours before PBSC from HLA-mismatched unrelated donors, after conditioning with 2 Gy TBI and fl udarabine 90 mg/m. Postgrafting immunosuppression included tacrolimus (day -3 to +180; tapered by day +365) and mycophenolate mofetil (tid days 0 to +42). HLA-compatibility was assessed at the HLA-A, -B, -C, -DRBI and DQBI loci: 13 pairs were mismatched for at least one HLA class I antigen (including 4 pairs who were also mismatched for 1 HLA-class II antigens (n=3) or 1 HLA-class I allele (n=1)), 1 pair was mismatched for 2 HLA class II alleles, while 6 pairs were mismatched for a single HLA class I (n=3) or HLA class II (n=3) alleles. Results: Median follow-up for surviving patients was 288 (range, 76-571) days. One patient with secondary AML had primary graft rejection, while the remaining 19 patients had sustained engraftment. Median donor T-cell chimerism levels on days 28, 100, 180 and 365 after HCT were 90%, 98%, 96%, and 98%, respectively. Grade II, III and IV acute GVHD were seen in 5, 2 and 1 patients, respectively, while 7 experienced NIH moderate/severe chronic GVHD. Three of 7 patients with measurable disease at transplantation achieved complete remission on days 41, 104 and 353 after HCT. Two patients died of nonrelapse causes on days 74 and 114 after HCT, while 3 died of disease progression. Projected 1-yr overall and progressionfree survivals were 77% and 61%, respectively. Conclusions: HLA-mismatched nonmyeloablative HCT with MSC co-infusion appeared to be safe, with MSC co-infusion possibly mitigating graft-versus-host alloreactivity without abrogating graft-versus-tumor effects. Survival is encouraging. [less ▲]
