We use the qualitative insight of a planar neuronal phase portrait to detect an excitability switch in arbitrary conductance-based models from a simple mathematical condition. The condition expresses a balance between ion channels that provide a negative feedback at resting potential (restorative channels) and those that provide a positive feedback at resting potential (regenerative channels). Geometrically, the condition imposes a transcritical bifurcation that rules the switch of excitability through the variation of a single physiological parameter. Our analysis of six di erent published conductance based models always nds the transcritical bifurcation and the associated switch in excitability, which suggests that the mathematical predictions have a physiological rel- evance and that a same regulatory mechanism is potentially involved in the excitability and signaling of many neurons.

This communication presents the main results coming from the survey led in Belgian hospitals as a part of the international study "Balanced ScoreCard in HealthCare". It shows that, even if the BSC is largely known in Belgian hospitals, its use is still relatively rare and limited essentially to a purely controlling perspective. [less ▲]

We herein describe the positional identification of a 2-bp deletion in the open reading frame of the MRC2 receptor causing the recessive Crooked Tail Syndrome in cattle. The resulting frame-shift reveals a premature stop codon that causes nonsense-mediated decay of the mutant messenger RNA, and the virtual absence of functional Endo180 protein in affected animals. Cases exhibit skeletal anomalies thought to result from impaired extracellular matrix remodeling during ossification, and as of yet unexplained muscular symptoms. We demonstrate that carrier status is very significantly associated with desired characteristics in the general population, including enhanced muscular development, and that the resulting heterozygote advantage caused a selective sweep which explains the unexpectedly high frequency (25%) of carriers in the Belgian Blue Cattle Breed.

A simple model of the carbon, alkalinity and strontium cycles is built up and used to interpret the carbon and strontium isotopic evolution of seawater over the Cenozoic as recorded in marine limestones. The idea that weathering fluxes have increased globally over the Cenozoic in response to the Himalayan uplift is critically examined. It is shown that such an increase of global weathering, postulated to explain the sharp increase in the Sr-87/Sr-86 ratio, is not compatible with the carbon isotopic record, if the budgets of carbon, alkalinity and strontium are considered simultaneously. Another scenario of the Cenozoic evolution of global weathering consistent with the carbon isotopic record is proposed in which the global weathering flux varies only slightly over the Cenozoic with a small increase between 15 Ma and the present. This second scenario appears more consistent with the reconstructed carbonate sedimentation rate and the evolution of the carbon isotopic fractionation in continental and oceanic environments.

The vibratory mill is used to decrease the single-wall carbon nanotubes (SWNTs) length and to increase their specific surface area. Electron microscopy, Raman spectroscopy, X-ray diffraction and BET measurements indicated that the optimum time of treatment seems to be 2 h. After that, the SWNTs quality decreases, with a complete disruption of the tubular structure leading to multi-layered polyaromatic carbon materials observed after 50 h. (C) 2004 Elsevier Ltd.

Heat conduction in nanosize systems has to be studied in settings involving microscopic details that are not seen in the classical Fourier theory. G. Chen has suggested [Phys. Rev. Lett. 86 (2001) 2297] a combination of the Cattaneo setting in which the velocity of the heat propagation is finite and the kinetic theory setting in which phonons are seen as heat carriers. In this Letter we show that if the Cattaneo and the kinetic theories are combined in a way that preserves the structure expressing their compatibility with thermodynamics (GENERIC structure) then both the Cattaneo and the kinetic equations become modified. The modified Cattaneo equations involve the term introduced by Chen and, in addition, new terms that are nonlinear in quantities that disappear at equilibrium. The kinetic equation is modified by new terms involving gradients of the heat flux and the local temperature. [less ▲]

Les invasions biologiques sont actuellement considérées comme l’une des atteintes majeures à la biodiversité. Néanmoins, elles sont encore souvent mal perçues du grand public. Ce court-métrage s’inscrit dans ce contexte et présente le cas de la Balsamine géante (Impatiens glandulifera ROYLE), espèce très esthétique, mais aussi particulièrement dommageable pour la flore des berges de cours d’eau, dans son aire d’invasion. La Balsamine fut introduite en Europe il y a plus d’un siècle, depuis les hauts-plateaux indiens et l’Himalaya, pour ses qualités décoratives. Après une phase de latence, elle a commencé à se répandre dans les milieux naturels, favorisée par les perturbations anthropiques et par un engouement des jardiniers pour l’espèce. Actuellement, elle est devenue problématique dans plusieurs vallées belges comme celle de l’Ourthe, l’Amblève ou la semois. Dans ce court-métrage, sous forme de fable, la Balsamine nous conte l’histoire de son invasion, tantôt aidée, tantôt enrayée par l’Homme. Le texte, entièrement original, est basé sur les connaissances les plus actuelles de l’espèce et des mécanismes sous-jacents à l’invasion. L’objectifs des réalisateurs est d’interpeller le spectateur sur la problématique tout en lui suggérant des actions préventives. [less ▲]
