We study the vortex structure in a Pb film deposited on top of a periodic array of ferromagnetic square microrings by combining two high-resolution imaging techniques: Bitter decoration and scanning Hall-probe microscopy (SHPM). The periodicity and strength of the magnetic pinning potential generated by the square microrings are controlled by the magnetic history of the template. When the square rings are in the magnetized dipolar state, known as the onion state, the strong stray field generated at the domain walls prevents the decoration of vortices. SHPM images show that the stray field generated by the dipoles is much stronger than the vortex field, in agreement with the results of simulations. Real-space vortex imaging has revealed that in the onion state, the corners of the square rings act as effective pinning centers for vortices. [less ▲]

An infinite word is S-automatic if, for all n ≥ 0, its (n + 1)st letter is the output of a deterministic automaton fed with the representation of n in the considered numeration system S. In this extended abstract, we consider an analogous definition in a multidimensional setting and present the connection to the shape-symmetric infinite words introduced by Arnaud Maes. More precisely, for d ≥ 2, we state that a multidimensional infinite word x : N^d → \Sigma over a finite alphabet \Sigma is S-automatic for some abstract numeration system S built on a regular language containing the empty word if and only if x is the image by a coding of a shape-symmetric infinite word.

En hydrologie, la manière de prendre en compte les zones urbaines diffère sensiblement selon les dimensions des bassins et la résolution temporelle des événements pluvieux étudiés. A petite échelle, les zones urbaines peuvent être modélisées grâce à une description détaillée des divers écoulements existants. En particulier, le réseau d’égouttage peut être décrit explicitement. A grande échelle cependant, les zones urbaines sont souvent représentées par des approches moins détaillées. Les modèles actuels prennent généralement en compte les surfaces imperméables par une adaptation des coefficients de ruissellement ou d’infiltration. Cette approche permet de générer des volumes de ruissellement corrects, mais ne permet pas de tenir compte de la modification de la dynamique de transfert des apports liée à la présence de réseaux d’égouttage. Une méthode de modélisation particulière a donc été développée pour tenir compte de ces éléments dans un modèle hydrologique global (WOLF), en quantifiant de façon précise les apports des surfaces imperméables grâce à des données d’occupation du sol en format vectoriel et en les propageant sans devoir implémenter l’entièreté du réseau d’égouttage. Ces développements ont alors été appliqués avec succès sur le bassin de la Berwinne, en Belgique. [less ▲]

The construct of emotional intelligence (EI) refers to the individual differences in the perception, processing, regulation, and utilization of emotional information. As these differences have been shown to have a significant impact on important life outcomes (e.g., mental and physical health, work performance and social relationships), this study investigated, using a controlled experimental design, whether it is possible to increase El. Participants of the experimental group received a brief empirically-derived El training (four group training sessions of two hours and a half) while control participants continued to live normally. Results showed a significant increase in emotion identification and emotion management abilities in the training group. Follow-up measures after 6 months revealed that these changes were persistent. No significant change was observed in the control group. These findings suggest that El can be improved and open new treatment avenues. (C) 2009 Elsevier Ltd. All rights reserved. [less ▲]

Several lines of evidence attest robust relationships between personality dimensions and emotions, including cognitive aspect of emotion. More particularly, many studies reported strong relationships between extraversion, the behavioral activation system (BAS), and the cognitive processing of positive information, on the one hand, and between neuroticism, the behavioral inhibition system (BIS), and the processing of negative information, on the other hand. Recently, DePascalis, Awari, Matteucci, and Mazzocco (2005) reported that personality traits modulated the effect of the emotional visual stimuli on the mismatch negativity (MMN). The aim of the present study was to replicate these data and extend them to other personality dimensions. Auditory MMN was recorded in normal subjects simultaneously to the presentation of emotional pictures selected as neutral, positive, or negative from the International Affective Picture System, and presented in randomized order. The results support the recent finding that personality (namely, BIS and harm avoidance) modulates the influence of emotional (negative) context on auditory information processing. The present findings suggest that the modulation by personality of change detection in the unattended environment as a function of context valence is limited to unpleasant context. [less ▲]

CO2 released from combustion of fossil fuels equilibrates among the various carbon reservoirs of the atmosphere, the ocean, and the terrestrial biosphere on timescales of a few centuries. However, a sizeable fraction of the CO2 remains in the atmosphere, awaiting a return to the solid earth by much slower weathering processes and deposition of CaCO3. Common measures of the atmospheric lifetime of CO2, including the e-folding time scale, disregard the long tail. Its neglect in the calculation of global warming potentials leads many to underestimate the longevity of anthropogenic global warming. Here, we review the past literature on the atmospheric lifetime of fossil fuel CO2 and its impact on climate, and we present initial results from a model intercomparison project on this topic. The models agree that 20–35% of the CO2 remains in the atmosphere after equilibration with the ocean (2–20 centuries). Neutralization by CaCO3 draws the airborne fraction down further on timescales of 3 to 7 kyr. [less ▲]

The distribution of transparent exopolymer particles (TEP) was investigated during a coccolithophorid bloom in the northern Bay of Biscay (North Atlantic Ocean) in early June 2006. MODIS chlorophyll-a (Chl-a) and reflectance images before and during the cruise were used to localize areas of important biological activity and high reflectance (HR). TEP profiles along the continental margin, determined using microscopic (TEPmicro) and colorimetric (TEPcolor) methods, showed abundant (6.1 x 10(6)-4.4 x 10(7) L-1) and relatively small (0.5-20 mu m) particles, leading to a low total volume fraction (0.05-2.2 ppm) of TEPmicro and similar vertical profiles of TEPcolor Estimates of carbon content in TEP (TEP-C) derived from the microscopic approach yielded surface concentration of 1.50 mu mol CL-1. The contribution of TEP-C to particulate organic carbon (POC) was estimated to be 12% (molar C ratio) during this survey. Our results suggest that TEP formation is a probable first step to rapid and efficient export of C during declining coccolithophorid blooms. (C) 2009 Elsevier Ltd. All rights reserved. [less ▲]

When to stop anti-TNF therapy in Crohn's disease (CD)? This is a very important question both for patients and physicians. There is no published evidence to clearly and definitely answer this question. However data on natural history of CD, long term safety of biologics, outcome after immunosuppressors (IS) cessation and some preliminary studies on biologics cessation may help us to discuss this topic. One could argue that there is currently no good reason to stop anti-TNF therapy in a patient who is in stable remission and tolerate this drug very well. The decision to stop an anti-TNF treatment is thus currently based on a compromise between the benefits/risks and cost of such long term treatment. While it appears now clearly that prolonged anti-TNF therapy is associated with favourable outcome with sustained remission, reduced surgeries and hospitalisation as well as absence of significant increase in mortality or cancers, the cost-effectiveness which is probably favourable for short and mid-term treatment (up to one year), may be less optimal for very long term treatment. In this perspective however, prospective studies should be performed to adequately assess long term evolution, disease outcome, safety and global cost of strategies based on treatment reduction with IS maintenance alone or even full treatment cessation.

The emergence of specialized cell types and their organisation into organs and tissues involve the temporal modulation of many genes that are essential for coordinating the correct timing of instructive signals. These transcriptional changes are orchestrated with a precision that reminds that of a classical symphony. Extracellular signals are transmitted to key integrators, which then orchestrate activation or repression of specific genes. In the last decade, class IIa HDACs have emerged as crucial regulators in various developmental and differentiation processes. This review focuses on the latest studies that have provided new insights into the biological functions of class IIa HDACs and discusses important aspects of their regulation. Elucidating cellular and molecular mechanisms by which functions of class IIa HDACs are modulated could potentially lead to new therapeutic opportunities for various diseases. [less ▲]
