The European transport policy has focused on sustainable transport solutions, among which intermodal transport is a key player. However, its efficiency is strongly dependent on the location of the container terminals. In this paper, a set of estimated potential locations is used as input for an iterative procedure based on the p-hub median problem that takes the variation in trans-shipment costs according to the number of trans-shipped containers into account. The final results are the optimal locations for European transfer terminals embedded in a hub-and-spoke network. [less ▲]

In this paper, we adopt a differential-geometry viewpoint to tackle the problem of learning a distance online. As this prob- lem can be cast into the estimation of a fixed-rank positive semidefinite (PSD) matrix, we develop algorithms that ex- ploits the rich geometry structure of the set of fixed-rank PSD matrices. We propose a method which separately updates the subspace of the matrix and its projection onto that subspace. A proper weighting of the two iterations enables to continu- ously interpolate between the problem of learning a subspace and learning a distance when the subspace is fixed. [less ▲]

Cet ouvrage est la première publication de synthèse de l’accord tripartite signé en novembre 2006 entre l’Université de Liège, la Universidad Central del Ecuador de Quito et la Universidade Federal do Amazonas de Manaus. Puisque cet accord concerne quatre domaines de recherche -le transport fluvial, la biotechnologie, l’anthropologie et la littérature-, ce livre offre des perspectives variées quant à la région amazonienne. Les articles inclus explorent les énormes richesses de cette région, soulignent les défis auxquels elle devra faire face et questionnent les imaginaires qu’elle suscite depuis l’Europe ou l’Amérique latine elle-même. L’ouvrage offre également des visions complémentaires dans la mesure où il noue un dialogue entre des chercheurs travaillant dans des contextes épistémologiques et géographiques très éloignés les uns des autres, une perspective interculturelle que nous désirons cultiver tout au long de cet accord tripartite et qui ne manquera pas d’interpeller le lecteur.

Around 30 to 50 % of obese subjects are « metabolically normal » (MHO) whereas numerous non obese subjects are « metabolically abnormal ». The distribution and the function of adipose depots seem to play a crucial role to explain this apparent discrepancy. In a first paper, we described the clinical and biological characteristics of these MHO individuals, analyzed the underlying pathophysiological mechanisms, and reported the prevalence of this syndrome in the adult population. This second paper aims at assessing the prognosis, especially regarding the risk of diabetes and cardiovascular disease, and at discussing the advantages and disadvantages of a classical therapeutic strategy of obesity among MHO individuals.

OBJECTIVE: To study the effectiveness and safety of budesonide/formoterol (Symbicort) Maintenance And Reliever Therapy (Symbicort SMART, AstraZeneca, Sodertalje, Sweden), a simplified management approach with one inhaler compared with conventional best practice (CBP) with multiple inhalers in patients with persistent asthma. DESIGN: Open-label randomised controlled parallel group trial, 6-month treatment. PARTICIPANTS: A total of 908 patients > or = 12 years of age, with persistent asthma receiving treatment with inhaled corticosteroids (ICS), either alone or in conjunction with long-acting beta(2)-agonist. MAIN OUTCOME MEASURES: Time to first severe asthma exacerbation and number of severe asthma exacerbations. RESULTS: No difference between groups was seen in time to first severe exacerbation (p = 0.75). Exacerbation rates were low in both groups. A total of 12 patients in the Symbicort SMART group experienced a total of 14 severe asthma exacerbations, and 19 patients in the CBP group experienced a total of 25 severe asthma exacerbations (annual rate 0.07 vs. 0.13 p = 0.09). The mean daily dose of ICS expressed in BDP equivalent was significantly lower in the Symbicort SMART group (including as-needed use) vs. in the CBP group (749 microg vs. 1059 microg; p < 0.0001). Mean scores in Asthma Control Questionnaire, 5 question version improved significantly in the SMART group compared with the CBP group (p = 0.0026). Symbicort SMART and CBP were equally well tolerated. The mean drug cost/patient/month was significantly lower for the patients in the Symbicort SMART group compared with patients receiving CBP (51.3 euros vs. 66.5 euros; p < 0.0001). CONCLUSIONS: In Belgian patients, a simplified regimen using budesonide/formoterol maintenance and reliever therapy was at least as effective at improving clinical control compared with CBP with a significantly lower ICS dose and significantly lower drug costs.

We propose WASP (lightweight and World-friendly Active packets for ephemeral State Processing), a new active platform based on Ephemeral State designed to allow bytecode interpretation on programmable datapath elements. We designed WASP to be a good compromise between flexibility (e.g. offering solutions in quality-adaptive multimedia flows, service discovery or mobility support) and safety (i.e. protection of router and network resource).

This testing design aims to assess, in a simulated way) a senior high school teacher competence that consists in being confronted with a problematic situation (a case) of school life that resort from educational psychology. In a first phase, data being insufficient, the teacher can merely elaborate a few explaining hypothesis. In a second phase, having obtained more information, he (she) can choose among a series of hypothesis the most likely one. In a third phase, if the hypothesis is confirmed, the teacher can imagine imagine his / her most appropriate reactions. In order to test simultaneously hundreds of students in the same amphitheatre, a series of sheets (formulas) are distributed, answered and then collected, additional information having ben provided in between two series of sheets. This explains the expression “fractionated”. [less ▲]

One of the most abundant and widely distributed groups of Helix-turn-helix (HTH) transcription factors is the metabolite-responsive GntR family of regulators (>8500 members in the Pfam database; Jan 2009). These proteins contain a DNA-binding HTH domain at the N terminus of the protein and an effector-binding and/or oligomerisation domain at the C terminus, where upon on binding an effector molecule, a conformational change occurs in the protein which influences the DNA-binding properties of the regulator resulting in repression or activation of transcription. This review summarises what we know about the distribution, structure, function and classification of these regulators and suggests that they may have a future role in biotechnology. [less ▲]

Human 16K PRL (16K hPRL) is a potent inhibitor of angiogenesis both in vitro and in vivo. It has been shown to prevent tumor growth in three xenograft mouse models. Here we have used a gene transfer method based on cationic liposomes to produce 16K hPRL and demonstrate that 16K hPRL inhibits tumor growth in a subcutaneous B16F10 mouse melanoma model. Computer-assisted image analysis shows that 16K hPRL treatment results in the reduction of tumor vessel length and width, leading to a 57% reduction in average vessel size. We thus show, for the first time, that administration of the 16K hPRL gene complexed to cationic liposomes is effective to maintain antiangiogenic activities of 16K hPRL level. [less ▲]

Objective Animal models of asthma mimic major features of human disease. Since the genetic background of experimental animals might affect hyperresponsiveness and inflammation, we studied its potential influence and the mechanisms leading to differences in strains. Methods We applied a mouse model of allergic asthma to BALB/c and C57BL/6 mice. Results BALB/c mice displayed greater levels of airway reactivity to methacholine than C57BL/6 mice. Moreover, BALB/c mice exhibited higher numbers of mast cells in lung tissue when compared to C57BL/6. On the contrary, eosinophil and neutrophil counts in bronchoalveolar lavage fluid (BALF) as well as peribronchial eosinophilia were greater in C57BL/6. IL (Interleukin)-4, IL-5, IL-13, and CCL11 levels measured in whole-lung extracts were higher in BALB/c, while, in sharp contrast, CCL11 and CCL5 levels were higher in BALF of C57BL/6 mice. Conclusions We observed phenotypic differences between C57BL/6 and BALB/c mice in an asthma model with different distributions of pro-inflammatory cytokines and inflammatory cells. [less ▲]
