Epidemiological data of atypical myopathy cases reported in France in autumn 2006 to spring 2010 were compared with those of European cases. During the observation period, 38.9% of European cases were French. The demographics of the French case were identical to the European cases but the survival rate was higher (32% vs. 26%).

Rangeland or natural arid pastures of Morocco are ecosystems where there is a natural or seminatural vegetation composed of steppes, shrubs and grassland. They cover about 82% of the Moroccan arid lands. These areas represent livelihoods for thousands of people and protect the country from desertification. Despite the importance of the rangelands and the threat of desertification, it is surprising that up to date there is no comprehensive assessment of their condition and their evolution, hindering any plan for desertification alleviation. However, the available information on selected pilot areas shows that these rangelands are threatened by desertification. It’s associated with biodiversity loss and contributes to climate change. The leading causes of land degradation are the human actions combined with climate. The establishment of a comprehensive surveillance system based on remote sensing, biophysics and socio-economic data must be envisaged to provide policymakers with an operational tool adapted to the spatio-temporal monitoring of desertification.

Dimebon, a compound recently proposed for a treatment of Alzheimer’s disorder, was suggested to have memory enhancing properties in pre-clinical and clinical studies. We investigated whether dimebon at doses acutely (0.1 mg/kg and 0.5 mg/kg) or repeatedly (0.1 mg/kg) administered to mice via i.p. injections, increases memory scores respectively in an appetitive and an inhibitory learning task. Acute treatment with dimebon at the dose 0.1 mg/kg did not affect learning scores in 3-month-old C57BL/6N. Acute treatment with higher dose of dimebon (0.5mg/kg) was found to enhance inhibitory learning in 3-month-old mice as shown in the step-down avoidance paradigm in C57BL/6N mice. In a model of appetitive learning, a spatial version of the Y-maze, repeated treatment with dimebon increased the rate of correct choices and decreased the latency of accessing a water reward after water deprivation. Repeated administration of dimebon also increased the duration of drinking behaviour during training/testing procedures although water consumption behaviour was not altered. Additional behavioural tests were carried out to investigate possible non-specific effects of dimebon on parameters of drinking, anxiety and exploration/locomotion. Our data suggest that dimebon enhances hippocampus-dependent learning in both appetitive and inhibitory tasks in mice. [less ▲]

A multi-criteria optimisation of a passenger ship is conducted in this paper. Minimum production cost and minimum steel weight are the both objective studied. Moreover the study answers to the following question: "From when will the higher costs of high tensile steel should be offset by a gain of steel weight?". For a passenger ship, a significant reduction of the steel weight, for a controlled raise of the gravity centre, should lead either to a reduction of fuel consumption either to an additional deck, which for a ship owner means a faster return on investment. Pareto frontiers are obtained and results are validated by classification rules. [less ▲]

Assessing soil structure is primordial when comparing tillage systems. Whilst most conventional techniques characterize global parameters, X-ray microtomography allows a characterization of the poral space at a µm-scale. These results, combined with data from pF curves, can form a solid basis in order to quantify soil physical fertility. Soil samples were taken from the organic topsoil on two Belgian experimental sites implementing both conventional tillage (CT, ploughing) and simplified tillage (ST, superficial works), without straw restitution: Gentinnes, Brabant Wallon (March 2010), and Gembloux, Namur (November 2010). On the Gentinnes site (Aba(b)1), CT and ST have been implemented since October 2005, with a beet/winter wheat rotation. On the Gembloux site (Aba(b)), CT and ST have been implemented since September 2008, with a winter wheat cultivation since end 2009. Tomography (10 samples for Gentinnes, 8 for Gembloux) and pF curves (10 samples for Gentinnes, 14 for Gembloux) were used for analysis. Pressure pans were used in order to obtain the pF curves on 100 cm³ undisturbed samples. Soil cores (3 cm diameter, 5 cm height) were scanned using a Skyscan-1172 µ-CT device. The conical beam, operating at 100 kV, produced images having a 17µm pixel size, using a 16-bit 1048×2000 pixels camera equipped with an aluminium filter. The raw images were then treated under Matlab® for binarization, using a thresholding loop to fit the measured and the calculated porosity of each sample (Beckers et al, 2011). The 2D binary images were then analyzed under Matlab® and Skyscan™ CT-analyzer. On the site of Gentinnes, pF analysis showed a greater available water content (between pF 4.2 and 2.5) for ST, and a greater efficient porosity (between saturation and pF 2.5) for CT. The differences in available water content, although not significant, were confirmed by site observation. Tomography analysis yielded the following: under ST, the pores are smaller and the anisotropy less developed. As for the poral connectivity, it was found greater in CT. On the site of Gembloux, however, no significant differences were found between the tillage systems concerning the pF curves. Tomography analysis showed smaller pores for simplified tillage, but the differences deduced by the tomographic analysis of the Gentinnes samples concerning connectivity and anisotropy were not found in this case. To conclude, from the results, the soil structure is found to differ between CT and ST. The pores tend to be smaller and less oriented in ST, whilst in CT pores are more connected. Soils undergoing a CT show a greater efficient porosity, whilst soils under ST display a greater available water content. However, these differences were mostly spotted on the Gentinnes site: in Gembloux, the differences between the samples were less marked. This could be due to the fact that the soil did not have time to differentiate yet (less than 3 years of tillage differentiation). More sampling is needed in any case before inferring general conclusions from these observations. A further analysis of the soil images, especially concerning pore orientation, will be done in order to fully exploit the tomography results. [less ▲]

Overlay routing is a promising way to improve the quality of service in the Internet but its main drawback is scalability: measuring the characteristics of the paths, exchanging the measurement results between the nodes and computing the best routes in the full mesh overlay network generally imply a high consumption of resources. In this paper, we design the basis of a lightweight self-organising one-hop overlay routing mechanism improving the latencies: we define criteria that rely on the information provided by an Internet Coordinate System (ICS) in order to provide a small set of potential one-hop shortcuts for any given path in the network with a small measurement cost. Our best criterion does not guarantee to find the best shortcut for any given path in a network but, even in networks with hundreds or thousands of nodes, it will restrict the search for potential shortcuts to about one or two percent of the total number of nodes.

Si pour Werner Herzog le rôle du spectateur semble réduit à celui d’un récepteur passif, pour Alexander Kluge en revanche, le spectateur et sa mémoire des images doivent conduire à l’élaboration d’un sens supérieur que la subjectivité du seul auteur serait incapable de faire émerger. Mais, leurs pratiques documentaires respectives se fondent aussi sur la perception d’une figure complexe, celle du cinéaste, constitutive d’une relation que le film contribuera à instaurer entre le réalisateur et le spectateur. L'identification de cette figure permet de "réconcilier" Alexander Kluge et Werner Herzog, deux représentants du Nouveau Cinéma Allemand, que la plupart des histoires de ce cinéma opposaient jusqu'à présent.

Several rectal biopsy techniques have been reported in horses and sites vary between 15cm or 30cm from the anus, and on the rectal floor or roof. The aim of this study is to evaluate the safety of the technique performed with a uterine biopsy claw and the diagnostic value of rectal biopsies. Eight rectal biopsies, taken at 2H, 4H, 8H, 10H of the rectal wall respectively, each at both 15cm and 30cm from the anus, were taken pre-mortem with a uterine biopsy claw from 12 horses destined to euthanasia. Seven of these horses suffered from weight loss or chronic diarrhoea and 5 were control horses euthanized for non-digestive reasons. At the post-mortem samples of duodenum, ileum, caecum, colon and rectum were taken and the rectum was inspected for macroscopic lesions. Histopathology was performed on haematoxylin-eosin stained slides of all samples. Statistical analysis was performed with Fisher’s test. Sampling was considered easier at 2H for a right-handed person. Necropsies show that 91% of biopsies located 30cm from the anus and 48% of biopsies located 15cm were taken cranial of the retroperitoneal reflection. Hematomas (44%) existed especially on the ventral side. Inflammation at histology was significantly more important in rectal biopsies sampled at 30cm from the anus and in sick horses compared to 15cm and control horses respectively. The results of this study suggest that rectal biopsy could be an interesting ancillary test in horses with chronic diarrhoea or weight loss, but also shows the limits of the technique. [less ▲]

Endotoxemia is the first mortality cause in equine intensive care. In humans with septic shock, some echocardiographic indicators are used to predict the efficiency of fluid resuscitation and outcome, allowing an early-goal-directed therapy. Echocardiography has never been investigated for this indication in horses. The aim of this study was to assess the prognosis value of echocardiographic and Doppler parameters of left ventricular (LV) function in horses with severe endotoxic shock. Twenty-one horses admitted to the clinic for colic with clinical signs of severe endotoxic shock underwent Doppler echocardiographic examination. LV echocardiographic and Doppler parameters were compared between the survivors (n=6) and the non-survivors (n=15) horses using a multivariable ANOVA analysis. The pre-ejection period to ejection time ratio (PEP/ET) of the Doppler aortic flow was significantly higher in the non-survivors than in the survivors group. All other measured parameters (including heart rate and end-diastolic-volume) were not significantly different between the groups. Doppler parameters of left ventricular function are subject to high variability and low repeatability in horses. This might explain that most variables were not significantly different between the two groups. Moreover, the number of investigated horses was limited, especially in the survivors group. However, with comparable HR and LV preload, a higher PEP/ET suggested a more compromised systolic dysfunction in the non-survivors. PEP/ET is often considered to be one of the best indicators of systolic function in horses and its measurement might therefore be useful in indicating the need for inotropic support in the management of horses with endotoxic shock.

Cette conférence étudiera les voyages financés par l’État français aux XVIIe et XVIIIe siècles en vue d’une acquisition de nouvelles connaissances sur le monde en dehors de l’Europe. Cette période fut témoin d’un changement radical de l’exploration scientifique outre-mer. Pendant le règne du Roi Soleil, et sous l’impulsion de Colbert, les voyageurs académiques partant de la France ainsi que certains Français résidant dans les territoires d’outre-mer recevaient des instructions pour mieux orienter leurs observations et améliorer la collecte de données, et ceci afin de recueillir des connaissances qui seraient utiles à l’État. Les projets à petite échelle prévalaient. Grâce au soutien d’institutions royales comme l’Académie Royale des Sciences ou le Jardin du Roi, des individus comme Charles Plumier, Joseph Pitton de Tournefort et Louis Éconches Feuillée ramenaient des échantillons et descriptions de « plantes utiles ». D’autres comme Jean Richer faisaient des observations astronomiques dans l’hémisphère Sud, ainsi améliorant non seulement la connaissance géographique, mais aussi les techniques cartographiques et les compétences dans le domaine de la navigation. Sous Louis XV vint une amplification des entreprises. La rivalité avec l’Angleterre conduisait les Français vers le Pacifique. Science, exploration et géopolitique se confondaient. De vastes équipes de chercheurs montaient à bord de navires militaires. Les expéditions enrichirent les collections scientifiques de Versailles et des institutions royales à Paris. Sous Louis XVI ce processus culmina dans l’expédition de La Pérouse. Trois aspects de la politique scientifique française dans le domaine de l’exploration seront analysés ici en détail: les mécanismes de patronage et de protection, les mécanismes d’approbation scientifique, et la mise à profit des connaissances rassemblées par les voyageurs.

Dans le cadre d’une analyse du caractère transversal de la politique de mobilité, nous avons voulu étudier dans quelle mesure les questions environnementales (en l’occurrence la pollution de l’air par les particules fines) étaient intégrées dans les programmes d’action des autorités responsables dans les deux principales régions de Belgique. Notre choix est motivé par le fait que de nombreux projets d’action ont été proposés par diverses instances (administrations, scientifiques, partis politiques et ONG), par exemple pour limiter le soutien public aux moteurs diesel ou pour réformer le cadre de mobilité dans certains quartiers urbains. Mais jusqu’ici, un seul dispositif (Lascoumes & Le Galès, 2005) a franchi la ligne d’arrivée : le règlement « Smog90 » qui limite la vitesse de circulation sur autoroutes à 90 km/h en cas d’épisode de smog reporté par la Cellule Interrégionale de l’Environnement. La politique de mobilité reste fortement marquée par une logique de développement d’infrastructures et ne prend que marginalement en compte l’impact des différents plans sur la qualité de l’air : greening of mobility is still limited. Pourtant, les champions de la cause ne manquent pas, que ce soit du côté des scientifiques ou des administrations régionales et fédérales en charge des politiques de santé et d’environnement (Hood & Rothsein, 2001). Pour comprendre les freins limitant la construction d’une approche transversale sur les questions « environnement – santé – mobilité », nous avons analysé les dispositifs mis en place pour rédiger et gérer les plans d’action sur la qualité de l’air, définis au niveau des régions et au niveau fédéral pour répondre aux obligations européennes (Directive CAFE, Clean Air For Europe, 2008). L’analyse montre comment la définition des objectifs européens en termes d’immission plutôt que d’émission limite la gamme des actions envisageables pour des petits états comme la Belgique et entre en conflit avec les projets politiques des deux Régions de se positionner comme des « logistic hubs » sur le territoire européen (Buisson-Fenet, 2008). Dans le cadre du projet de recherche SCoPE, une enquête en ligne de type Delphi associant des acteurs de l’action publique en charge de la mobilité et de l’environnement (scientifiques ou administratifs) a été menée au sein des deux plus grandes régions. La recherche montre que chacune d’elles a développé des formes de gouvernance différentes, l’une en réseau de coopération souple et l’autre sous forme d’une agence centralisée. Néanmoins, les acteurs des deux régions soulignent les mêmes freins au développement d’approches politiques transversales : un contrôle strict de l’agenda organisé par les cabinets politiques qui sont en Belgique de larges structures peuplées d’experts nommés par les partis politiques. Alors que l’ambition et la nature du cadre européen demanderaient le développement d’une approche transversale et transpolitique, les répondants dénoncent l’absence de coopération entre d’un côté les scientifiques et experts technico-administratifs et de l’autre, les responsables politiques : les incitants à la création de mesures transversales ne peuvent se dessiner qu’à la suite de situations de crise ou sous la pression d’un tiers, par exemple le public, les ONG ou les médias. À travers ses aspects multi-niveaux, interdisciplinaire et transversal, la politique de qualité de l’air, telle que perçue par les répondants au Delphi, témoigne de la difficulté de dessiner des nouveaux instruments d’intervention et de la nécessité de prendre en considération les dimensions administratives, politiques et sociales pour organiser un changement de l’action publique (Simoulin, 2003).

Le projet Walphy a pour objectif d'améliorer la qualité écologique de deux masses d'eau, le Bocq et l'Eau Blanche, dans le but de répondre aux exigences de la Directive européenne sur l'Eau (2000/60/CE). Suite à une évaluation de la qualité physique du milieu, des travaux d'aménagement sont entrepris suivant 2 axes de réhabilitation : - la continuité longitudinale qui concerne la libre circulation des poissons et des sédiments, - la continuité transversale responsable des échanges du cours d'eau avec ses zones annexes. Ces chantiers - pilotes font l'objet d'un suivi scientifique afin d'analyser les impacts sur l'hydromorphologie (transport des sédiments, diversité des habitats …) et sur l'écologie (végétations, macroinvertébrés et populations piscicoles). Le projet a démarré en janvier 2009, il est co-financé par l'Union Européenne pendant 5 ans. La coordination est assurée par la Direction des Cours d'Eau non Navigables (DCENN - DGARNE) en collaboration avec les Universités de Liège (Laboratoire d'Hydrographie et de Géomorphologie Fluviatile LHGF) et de Namur (Unité de Recherche en Biologie des Organismes URBO).

In the field of Preference Learning, the Ranking by Pairwise Comparison algorithm (RPC) consists of using the learning sample to derive pairwise comparators for each possible pair of class labels, and then aggregating the predictions of the whole set of pairwise comparators for a given object in order to produce a global ranking of the class labels. In its standard form, RPC uses hard binary classifiers assigning an integer (0/1) score to each class concerned by a pairwise comparison. In the present work, we compare this setting with a modified version of RPC, where soft binary class-probability models replace the binary classifiers. To this end, we compare ensembles of extremely randomized classprobability estimation trees with ensembles of extremely randomized classification trees. We empirically show that both approaches lead to equivalent results in terms of Spearman’s rho value when using the optimal settings of their metaparameters. However, we also show that in the context of small and noisy datasets (e.g. with partial ranking information) the use of class-probability models is more robust with respect to variations of its meta-parameter values than the hard classifier ensembles. This suggests that using (soft) class-probability comparators is a sensible option in the context of RPC approaches. [less ▲]

This paper presents a comparative study showing the environmental profile of structural members used in the construction domain. The functional unit is a column that is realistic in terms of dimensions and load bearing capacity, made of steel or high strength steel sections, steel and concrete (composite), reinforced concrete, solid wood and glue-laminated wood. The design of the columns is made following the Eurocodes. Several environmental impacts are assessed, such as the global warming potential and energy consumption while also focusing on the acidification potential. The results are presented in the forms of bar charts for each considered column. For steel and concrete, depending on the source of information, the inven-tory can vary substantially e.g. the CO and CH4 emissions. Several sources of information are provided and used to perform a brief sensitivity analysis. The influence of the recycling of steel taking into account the IISI methodology will also be discussed.

This study presents the natural as well as human factors which are responsible for the environmental degradation and the increasing vulnerability of the population of Bukavu to natural hazards. The city of Bukavu is located within the Albertine rift, a region which is prone to seismic activity. Moreover, the accentuated topography, the lithology and climate regime contribute considerably to the occurrence of both geomorphologic and hydroclimatic hazards. Over the last few decades the city has evolved at an exponential pace, without appropriate urban planning. Between 1970 and 2008 the population increased more than four times within a constant area of about 60 km2. The related change in land use has drastically amplified both the frequency and impact of natural hazards in the city. The zones at high risk of mass movements and flooding have been identified and mapped using remote sensing and Geographical Information System (GIS). The changes in land use and population density were also studied, and we propose several approaches to raise the resilience of the population in order to reduce the impact of natural hazards on the city.

Most of the IPCC-AR4 Atmospheric Global Circulation Models (AGCM) predict an increase of the Antarctic Surface Mass Balance (SMB) during the 21st century, driven by an increase of snow falls, which would mitigate the sea level rise. Much of the SMB change is expected to happen in the Antarctic coastal area, which concentrates the major part of the snow falls. This area is also were we find complex processes of precipitation, sublimation, melt and redistribution by the wind. High-resolution modeling (5 to 10 km) is necessary to accurately capture the effects of the fine topography on the atmospheric variables but limitations in computing resources prevent such resolution at the scale of Antarctica in full climate models. We present here a downscaling method yielding to a 10-km resolution of the SMB for the 21st century, from ~60-km resolution LMDZ4 AGCM outputs. We compute orographic precipitation induced by the finer topography, as well as the boundary layer processes leading to melt and sublimation. It shows a clear improvement of the SMB distribution in coastal regions with consequences on the grounded ice sheet SMB estimation. [less ▲]

Transient creep strain has to be included within the constitutive relationships for concrete at high temperatures. However, the necessity of taking into account this term explicitly is not clearly defined. In the Eurocode 2 uniaxial concrete material model, transient creep is included implicitly. This paper aims to highlight the capabilities and limitations of concrete uniaxial models at elevated temperatures for thermo-mechanical behaviour modelling, depending on the implicit or explicit consideration of transient creep strain in the model. The characteristics inherent to the two types of models are described and compared. It appears that one of the major limitations of implicit models concerns the unloading stiffness because implicit models treat transient creep as reversible. Based on numerical analysis performed on loaded concrete columns subjected to natural fire, it is shown that the stress-temperature paths experienced by structural concrete are varied and complicated and that concrete material models cannot handle properly these complex situations of unsteady temperatures and stresses without explicit consideration of transient creep. The paper proposes a new formulation of the Eurocode 2 concrete material model that contains an explicit term for transient creep. The new model is implemented in the software SAFIR and validated against experimental data of the mechanical strain developed by concrete cylinders under different unsteady temperatures and loads. It is shown that the actual material behaviour is better matched with the new explicit model than with the current implicit Eurocode 2 model. Finally, a comparison is given between experimental and calculated results on an axially restrained concrete column subjected to heating and cooling. [less ▲]

Angiotensin converting enzyme inhibitors are recommended therapy in human and canine patients with congestive heart failure (CHF), but little is known concerning their efficiency to treat horses with CHF. Enalapril has been shown to be poorly absorbed in horses and quinapril has been shown to decrease the severity of the insufficiency and to increase the stroke volume (SV) and the cardiac output (CO) in horses with mitral regurgitation (MR) without signs of CHF. The objective of this cases report was to evaluate the effect of quinapril associated with routine treatment in horses with CHF. Three horses with clinical, echocardiographic and electrocardiographic signs of severe MR, CHF and secondary atrial fibrillation were studied (Fig 1 to 3). None of them had been previously treated for those problems. According to the ACVIM classification system for management of canine CHF, they were therefore classified in class C. They were treated with quinapril 0.2mg/kg SID PO, digoxin 0.011mg/kg BID PO, and furosemide 1mg/kg BID IM. Standard echocardiographic and Doppler measurements were performed before treatment (T0), and 1 and 4 weeks after starting treatment (W1 and W4, respectively). All horses showed a transient clinical improvement (decrease of edemas and disappearance of the dyspnea) after 1 week of treatment, but clinical signs deteriorated within the following weeks in 2 horses that were euthanized for ethical reasons. The third horse kept a steady clinical status and was discharged with the treatment pursued at home. Evolution (in %) of main echocardiographic parameters at W1 and W4 compared to T0 values are showed in Table1. Large individual variations in response to the treatment were seen. Nevertheless, in all horses, a decrease of the Heart Rate (HR) was observed after 1 week of treatment, but the HR increased again after 1 month of treatment (Fig 4). On the contrary, no increase in SV or CO, and no decrease in LVIDd were seen in response to treatment (Fig 5). In the 2 horses that were euthanized, the fractional shortening (FS) and the pre-ejection to ejection time ratio (PEP/ET) decreased and the mitral E peak velocity increased with treatment, whereas they followed the opposite evolution in the surviving horse. No conclusion can be drawn from this study because of the limited number of studied cases. However, it would be interesting to extend it to additional cases and to less severely affected cases (i.e. horses classified in class C after initial treatment or class B horses). Negative chronotropic effect of digoxin was suggested after 1 week of treatment since a decrease of the HR was observed in all horses. However, this effect seemed to decrease after 1 month of treatment. Those preliminary results of echocardiography suggest that quinapril in association with digoxin and furosemide at the used dosage could be inefficient to reduce the left ventricular filling pressure and to improve the myocardial contractility in horses with severe CHF. This could however be due to the fact that the 3 studied horses were cases refractory to classic treatment (thus to be classified in class D). [less ▲]

Introduction: The tendon is a tissue which does not heal easily. Recently, several studies have demonstrated the positive effects of platelets on the healing process of tendons. A local injection of platelet–rich plasma (PRP), which releases in situ many growth factors, has the potentiality to enhance the tendon healing process. The aim of our experiment was to ascertain by an original mechanical measure whether the use of PRP was of interest for accelerating the healing process of rats’ Achilles tendons after surgical induced lesion. Methods: A 5mm defect was surgically induced in 90 rats’ Achilles tendon. Rats were divided into 2 groups of 45: (A) control (no treatment) and (B) PRP treatment. Rats of group B received a PRP injection in situ after the surgery. Afterwards, rats of both groups were placed in their cages without immobilization. After 5, 15 and 30 days, 10 traumatized Achilles tendons of each group were dissected and removed. Immediately after sampling, tendons were submitted to a biomechanical tensile test up to rupture, using a “Cryo-jaw”. After that, transcriptomic analyses were made on the tendon samples, to study the expression of type III collagen, matrix metalloproteases and tenomodulin. A hydroxyproline dosage was done to quantify the collagen in the tendon during its healing process. Tendons of the 15 remaining rats of each group were subjected to a histological study, respectively at day 5, 15 and 30 (5 rats for each time). Results: We demonstrated that the force necessary to induce tendon rupture during biomechanical tensile test study was greater for tendons which had been submitted to an injection of PRP compared to the control group: +19% (day 5), +30% (day 15) and +43% (day 30). Histological study showed that PRP could enhance cells proliferation, angiogenesis and collagen organisation. Our biochemical analyses did not explain beneficial effects of PRP. Indeed, there was no significant difference neither between the expression of different studied genes, nor in the quantity of hydroxyproline between both groups. Conclusion: This experimentation has shown that a PRP injection could accelerate the tendons healing process and improve its quality. [less ▲]

Since the days the investigating officers used ”pin maps” to locate and to think about crime events, crime mapping has become widespread thanks to spatial analysis mainly supplied by GIS-like software. In particular these methods suit well to geographic profiling devoted to crime series characterised by a single offender and hence limited space and time variability. Although spatial techniques are now regularly performed to delineate an offender’s area of residence, the temporal dimension is underemployed due to the wider uncertainty of time records. This paper proposes a methodology based on a least-squares adjustment in order to cope with this temporal issue for determining the most probable offender’s residence. Moreover, a chi-square test is described to check the significance of the solutions suggested by the method. The process is carried out on the real road network which has been discretised (rasterised) for computing convenience. Three simulations show the validity of the reasoning. Finally the main time and speed assumptions introduced in the model are discussed paving the way for further research. [less ▲]

Asteroseismology is a recent branch of astrophysics that studies the interiors of stars by the interpretation of their pulsation spectra. A wide variety of stars exhibit pulsations, including gravity-modes (driven by buoyancy) that usually penetrate deep inside the stars. By probing these deep layers unreachable from classical observations, the g-mode oscillations bring invaluable information for stellar evolution and astrophysics in general. I will illustrate in my talk the power of g-mode asteroseismology by the example of Extreme Horizontal Branch stars, that are on an intermediate stage of evolution, and show how g-modes allow us to determine the properties of the cores in these stars, including their convective characteristics, size and composition.
